Description

The invention relates to the design of devices for sifting and dewatering fine-grained material and can be used in the oil industry for cleaning mud, mining construction and other industries.

A device for sifting and dehydration of fine-grained material, including a base on which mounted on the shock absorbers vibration frame with a sieve and a horizontal vibrator [1].

The disadvantage of this device is the difficulty of regulating the separation process.

Closest to the invention in technical essence and the achieved effect is a device for sifting and dewatering fine-grained material, comprising a housing with a sieve located inside it, mounted on shock absorbers and connected to a vibro frame, a loading chute and devices for unloading material [2]. However, the known design is inherent in the impossibility of adjusting the amplitude of the oscillations of the sieve during operation of the device.

The purpose of the invention is the ability to control the amplitude of the oscillations of the sieve during operation of the device by changing the load on the shock absorbers.

This goal is achieved in that the device for sifting and dehydration of fine-grained material, including a housing with a sieve located inside it, mounted on shock absorbers and connected to a vibro-frame, forehead and devices, materials, is equipped with a unit made in and flexible connection, one; mounted on a dinen drum with a vibrating frame, mounted on a loading chute.

The drawing shows a device for screening and dewatering of fine-grained material.

The device comprises a base 1, on which, by means of shock absorbers 2, a casing 3 is installed with a sieve 4 located inside it. The casing 3 is connected to a vibro-frame 5, inside of which there is a vibrator 6 with a vertical shaft, at the ends of which there are plates with unbalanced weights. Material loading is carried out by means of a loading chute 7, unloading of separation products is carried out through unloading chutes 8 and 9. On the chute, an аз ед ед грузки ед ед ед ед ля грузки грузки вы с грузки грузки вы грузки грузки грузки грузки грузки конец конец конец конец конец конец конец конец конец конец конец конец конец работает 10 10 10 10 10 10 10 10 10 10 10 уст уст уст уст уст уст уст through flexible communication 11.

The device at once.

The material to be treated, the thief with the sludge contained therein, is fed through the loading chute 7 to the center of the sieve 4. Under the action of the vibrator 6, the vibratory frame 5 and the casing 3 with the sieve 4 perform spatial circular vibrations relative to the vertical axis passing through the center of the vibrating frame, performing sequentially alternating tilts in different directions. In this case, the particles of sludge moving along the surface of the sieve are removed through the trough 9, and the solution passing through the sieve is transported along the trough 8. The inclination angle and magnitude of the amplitude of the oscillating system depend on the position of the debris "of the weights of the vibrator and the axial resistance of the spring shock absorbers in the vertical plane .

Depending on the magnitude of the amplitude of the oscillation, the trajectory of the particles on the surface of the sieve and the residence time of the material on ¹ it changes.

Rough regulation of the particle path along the sieve surface is carried out by radially moving unbalanced weights after the device is stopped. Depending on the fractional composition of the drilling fluid leaving the well, the oscillation amplitude and particle path are controlled during operation by changing the load on shock absorbers. This is achieved by reloading or partial unloading of the spring shock absorbers 6 from the mass of the vibrating frame 5 by lowering it or lifting it with the help of a drum 10 mounted on the loading chute, one end of the rabana 10, with a vibro-frame

7, and flexible connection 11, which is fixed on the baa of the other - connected to 6 in the center.

This embodiment of the device allows you to quickly and accurately depending on the properties of the drilling fluid coming from the well, to regulate the amplitude of vertical vibrations and the configuration of the trajectory of the movement of sludge along the grid, achieving their optimal values on the go during operation of the device. This increases the throughput of the device and allows you to work when cleaning the drilling fluid at optimal conditions.
