Vibrating sieve sv 1400 2. Vibrating sieves type sv
Coarse cleaning agents are mainly represented by mechanical vibrating units (vibrating screens) capable of removing large sludge larger than 100 microns. without much disturbance in the rate of pumping of the drilling fluid.
In vibrating screens, cuttings are separated from the drilling fluid using a screening device. Single-tier twin vibrating screens SV-2, SV-2B, LVS-1 and single-tier double-screen vibrating screens VS-1 are used. According to the principle of operation, all vibrating screens are similar.
The figure shows a schematic representation of a vibrating sieve. Its main elements are as follows: a tray for collecting a purified solution 7, a receiver with a flow distributor 2, a vibrating frame 5 with a grid 4, a vibrator 3, shock absorbers 6.
Vibrating screen SV-2
There are no cardinal differences among vibrosieves. So, the vibrating screen SV-2 consists of a welded frame 1 with a receiving tank, on which a distribution chute 2, two electric motors 3 are installed to drive the vibrating frame 5 and shock absorbers 6. Each of the two vibrating frames rests on four rubber shock absorbers, has a vibrator with an eccentric shaft , which is driven by an electric motor by a V-belt transmission, closed by a fence 4. A working mesh is stretched between the drums 7. Grids are inclined horizontally at an angle of 12-18 degrees.
In VS-1, a replaceable cassette with nets is fixed on a vibrating frame. The vibrating frame rests on four shock absorbers made of coiled coil springs attached to the sieve frame.
The frame consists of a base, two sidewalls, bolted together. The sidewalls are additionally fastened with a spacer, a drive frame, and a vibrator housing. A shaft with imbalances is installed in the vibrator housing, providing the necessary oscillation amplitude. An electric motor is located on the drive frame, connected to the vibrator by a V-belt drive. On the opposite side of the drive frame, weights are installed to balance the drive.
During installation, vibrating screens are installed on the circulation system cleaning unit above the tank and fastened with bolts. Deviations of a bed from horizontal position - no more than 5 mm. Around the vibrating screen, a platform with a fence with a width of at least 0.75 m is mounted. The inlet pipe (chute) of the vibrating screen is connected by a pipe to the wellhead. To bring the vibrating screen into working position, unscrew the four transport bolts securing the vibrating frame. Install the electric motor and put on two V-belts. When installing cassettes with nets, check the presence of rubber protrusions on the base of the net and the correctness of their location. The cassettes are installed in such a way that equal gaps remain on each side, after which the bolts are tightened with clamps until the spring coils touch.
Vibrating sieve LVS 1 with linear vibrations is designed by analogy with the best foreign samples of similar products. Linear single-tier vibrating sieve LVS-1 is designed to clean the drilling fluid from drilled rock particles when drilling oil and gas wells. Equipped with two flexible three-layer cassettes. Depending on the version of the equipment, the magnitude of the disturbing force of the vibrator can be adjusted.

The principle of operation of the vibrating sieve
Loose mass is evenly fed through the upper central pipe with the help of a feeding device (sluice or screw feeder, chain conveyor, dispenser, etc.) into a sieve (or into a battery of sieves - depends on the design).
Passing successively through several sieves with different mesh sizes, the initial product is separated into fractions due to vibrations of the vibrating frame. Particles smaller than the sieve cell pass through it, while larger particles are retained on the mesh and, under the influence of vibrations, are discharged through the side pipe. In one vibrating separator, from 1 to 4 decks (sieves) can be installed, which ensures the separation of material from 2 to 5 fractions.
The three-dimensional movement of the screening surface combines the movement of a flat screen classifier and a screen.

The platform vibrators are mounted on opposite sides of the frame at an angle of 180° relative to each other and create a three-dimensional vibration of the vibrating screen. Changing the angle of inclination of the vibrators allows you to change the direction of vibration, and the regulation of the location of unbalances and the regulation of the frequency of rotation of the vibrators allows you to change the speed and performance of the vibrating screen. Thus, it is possible to change the nature of the movement of the product and its residence time on the sieve, which makes it possible to use a vibrating sieve for sifting a wide range of powders with different particle sizes and shapes, bulk density, compactability and stickiness.
Loose mass is evenly fed through the upper central pipe with the help of a feeding device (sluice or screw feeder, chain conveyor, batcher, etc.) into the sieve. Passing successively through several sieves with different mesh sizes, the initial product is separated into fractions due to vibrations of the vibrating frame. Particles smaller than the sieve cell pass through it, while larger particles are retained on the mesh and, under the influence of vibrations, are discharged through the side pipe. In one vibrating separator, from 1 to 3 decks (sieves) can be installed, which ensures the separation of material from 2 to 4 fractions.

The vibrating screen is available in stainless steel or carbon steel.
Advantages of the vibrating sieve:
- high sieving efficiency
- the ability to select the optimal modes for various materials
- high degree of maintainability. (replacement of the frame with a mesh, if necessary, is carried out in 10 ...
- high reliability
- dust tightness of the device
- continuous operation
- low energy intensity
- low dynamic loads on the base
Feature of vibrating sieves type CB:
A feature of the operation of vibrating sieves of the SV type is the nature of the oscillations of the screening surfaces. Unlike other designs of vibrating sieves, CB-type vibrating sieves use spatial (three-component) vibration of screening surfaces. This nature of the oscillations provides a continuous change in the magnitude and direction of inertial loads, which makes it possible to obtain optimal sieving conditions, especially for materials with particle sizes close to those of the mesh cell. The three-dimensional movement of the screening surface combines the movement of a flat screen classifier and a screen.
Application:
In the food industry - factories for the production of powdered milk, confectionery factories, oil and fat plants, meat processing plants, manufacturers of flavorings and spices and many other enterprises; in the chemical industry - enterprises manufacturing welding electrodes, synthetic detergents, chemical fertilizers, PVC; in the construction industry - dry building mixes; in pharmaceutics - for control screening of drugs and in many other technological processes screening of loose materials.

Technical description:
1 - cover, 2 - shell, 3 - mesh on the frame, 4 - discharge pipe, 5 - vibration isolator, 6 - vibration exciter, 7 - frame, 8 - electric motor
Vibrating sieve (vibrating sieve) SV is a single-mass oscillatory system of a resonant type, the oscillating parts of which include a housing with sieves, an unbalanced vibration exciter connected to the housing, which sets the vibrations to the system. The rotation of the vibration exciter is transmitted from the engine pos.8 through the clutch. The oscillating parts of the sieve rest on the frame pos.7 through vibration isolators pos.5.
The driving force of the vibration exciter is created by two unbalances rotating on a vertical shaft: the upper one, located approximately in the center of mass of the oscillating parts of the sieve, and the lower one.
The sieve vibrates with a frequency equal to the motor shaft rotation frequency, and each point of the oscillating parts moves along a closed elliptical trajectory located at an angle to the horizontal plane. The dimensions of the oscillation trajectory (horizontal and vertical amplitudes) depend on the magnitude of the static moments of the upper and lower unbalances.
The starting material is fed into the loading pipe (see Fig.).
The fractions obtained after sifting leave the sieve through the discharge nozzles.
The intensity of screening is regulated by the amplitudes and the angle of rotation between the upper and lower unbalances.
The horizontal and vertical oscillation amplitudes are controlled by changing the static moment, respectively, the upper and lower unbalances.
"Vibrotechnika" develops, manufactures and introduces vibrating sieves (CB-0.4, CB-0.6, CB-0.9, CB-1.2).
Vibrating sieves are designed for dust-tight sifting into several fractions of loose materials, not prone to sticking, no larger than 30 mm, with temperatures up to 323K (+50°C).
They are a single-mass freely oscillating resonant system. They consist of a working body, a vibration exciter, elastic links, a frame and an engine. The working body includes a set of cylindrical shells and screening surfaces in the form of grids, mounted on frames, assembled with quick-release clamps, the rotation of the vibration exciter shaft is transmitted from the engine through an elastic petal clutch. The loading and unloading pipes are equipped with rubber seals.
They are high-performance, efficient and reliable devices for sieving powdery, granular and lumpy materials and can be used for dewatering materials. Long-term operating experience shows that vibrating screens are not inferior to foreign analogues in terms of their technical level and are significantly cheaper.
The performance of the vibrating screens is subject to experimental determination in each specific case, depending on the properties of the processed material and the size of the grid cells. Vibrating screens are made with a working body of carbon or stainless steel.
When delivered, the sieves are usually equipped with meshes with a mesh size of 2 and 0.63 mm. Together with the screens, for an additional fee, devices for tensioning the screens on the frames and a spare frame are supplied, which can significantly reduce the time to replace the screen.
