Abstract

The invention relates to equipment for the continuous purification of suspensions and can be used in the food, chemical, petroleum and other sectors of the industry. The purpose of the invention is to increase the efficiency of purification of suspensions and increase the throughput. For this, a suspension is fed into the internal cavity of the cleaning surface through the receiving ports of the disk and is evenly distributed by the rotating fender cone. The use of woven mesh increases the throughput of the upper truncated cone, and fixing the retaining rings on the woven mesh prevents its deflection. Under the influence of vibration, the cleaning surface of the suspension passes through the cells of the woven wire mesh, separates from the sludge and is discharged through the drain pipe. The heavy particles are deposited on the rotating precipitation cone and lowered onto the vibrating lower truncated cone, pass through the windows of the slurry pipe, through which they are directed into the screw conveyor, pressed and removed from the device. 3 il.

Description

The invention relates to equipment for the continuous purification of suspensions and is used in the food, chemical, petroleum and other sectors of the industry.

The purpose of the invention is to increase the efficiency of purification of suspensions and increase the throughput.

FIG. 1 shows a vibrating settler, a general view, a section; FIG. 2 shows the assembly I (tensioning and sealing the woven mesh of the cleaning surface) in FIG. one; in fig. 3 - the node P (woven mesh cleaning surface) in FIG. one.

The vibratory sump consists of a base 1 on which vibrators 2 are installed, a receiving box 3 with a drain pipe 4 for the cleaned suspension and a screw conveyor 5 with a moving cone 6 for pressing and removing the scrap. In the center of the base there is a bearing housing 7, on the bearings of which there is a slurry pipe 8 with receiving windows 9. The sludge pipe is rigidly connected to the lower truncated cone 10 of the cleaning surface, on the periphery equipped with a skirt 11 with a flange 12 fixed on it and a movable flange 13, interacting with the upper cone 14 of the cleaning surface, made of woven mesh. Vibrators 2, interacting with the skirt 11 of the lower truncated cone 10, give it a reciprocating movement around the axis with a given frequency and amplitude of vibration.

In the upper part of the rotating slurry nozzle 8 above the receiving windows 9, an axis 15 is pressed in, from the other end on

which is fixed disk 16 with receiving Windows 17 and the groove 18 on the periphery of the disk, serving to install, center and stop the woven mesh upper truncated cone 14 using the upper retaining ring 19.

The woven fabric is tensioned by placing the movable flange 13 into the lower retaining ring 20 with the help of pin 21s. Installed in the movable flange 13 and passing through the fixed flange 12, springs 22 and nuts 23 with tongues 24. the mesh deflects the forming cone of the cone, which affects the depth of purification of the suspension in the direction of deterioration. To prevent sagging when the woven mesh is tensioned, the cleaning surface is provided with intermediate retaining rings 25 The connection between the upper and lower cones is sealed by the transition of the woven mesh from conical to cylindrical shape on the upper edge of the skirt 11 when it is tensioned.

In the internal cavity of the cleaning surface D IIO7 1 IO nosti on bearings 26 and /; / with the possibility of free rotation are mounted on the axis 15 in the form of a closed volume of the fender 28 and the settling 29 horses, which serve to evenly distribute the unpurified suspension coming from the receiving pipe 30, sludge sedimentation and reducing the volume of the internal cavity of the cleaning surface.

To prevent oxidation of the suspension being cleaned and damage to the woven mesh in operation, the cleaning surface is closed by an outer shell 31 coaxially mounted on the receiving box 4 of the base 1. The vibro-settling tank works as follows: The cleaned suspension is fed through the receiving pipe 30 and the receiving windows 17 of the rotating disk 16 into the internal cavity of the cleaning surface, where they are evenly distributed using the baffle cone 28 The vibrators 2 interacting with the cleaning surface and the drive of the screw conveyor 5 are activated. The vibrations of the cleaning surface of the suspension pass through the cells of the woven wire mesh and are separated from the sludge and collected in the receiving box 3, from where the discharge nozzle 4 is removed from the device. Suspended particles separated from the suspension in a vibrational field are deposited on the settling cone 29 and, under the influence of gravity and descending flows of the suspension being cleaned, are moved along the surface of the precipitation cone to the lower truncated cone 10. At the lower truncated cone 10, the slime concentrates as it moves from the periphery to center to rotating sludge nozzle 8

Through windows 9, the concentrated sludge enters the sludge pipe 8, through which it is guided into the shnekovyy panspopter 5 Screw conveyor 5 sludge is squeezed and removed from the device. SBB The degree of squeezing of the slurry is controlled by pressing the gland horse. due to the use of the effect of the destruction of the suspension in the vibration field of the effect of the vibrating cell of the cleaning surface and the effect of sedimentation of suspended particles in the vibration field. The combined use of these effects makes it possible to separate suspended particles from the size considerably smaller sizes of the perforation cells of the cleaning surface. The depth and degree of cleaning of the suspension by the vibrating separator are adjusted and set by the magnitude of the vibration frequency with an amplitude of at least half the size of the cells. perforation cleaning surface. An increase in the frequency of vibration of the cleaning surface simultaneously with an increase in the depth and degree of purification of the suspension is accompanied by an increase in the throughput capacity of the sump.

The increase in throughput .. of the pit tank is facilitated by an increase.: -. - ° of the cross section of the cleaning surface - due to the use of woven mesh instead of. In turn, this provides. There is a decrease in metal consumption and equipment dimensions.
