The diameter of the left end of the dewatering barrel 400 is smaller than that of the right end, the lowest point of the opening of the left end and the lowest point of the opening of the right end are at the same horizontal height, specifically, the dewatering barrel 400 is divided into two parts along the diameter of the dewatering barrel, one part is in a columnar structure, the other part is in a frustum structure, one half of the columnar structure of the dewatering barrel 400 in an initial state is positioned below, and the lower surface of the dewatering barrel 400 is always a horizontal plane. The dewatering barrel 400 is rotatably arranged in the charging barrel 120, a discharging pipe 130 is arranged at the lower end of the charging barrel 120, a feeding component 200 is arranged at the left end of the dewatering barrel 400, and the feeding component 200 comprises a conveying pipe and a feeding hopper; the material conveying pipe is communicated with the left end of the dewatering barrel 400; the feeder hopper is funnel-shaped, and the lower extreme is connected with the conveying pipeline. The feeding assembly 200 is used for guiding the solution containing the filter residue into the dewatering barrel 400, and meanwhile, the solution flows from left to right to initially flatten the filter residue, so that the surface area of the filter residue is increased.

The blocking rings 411 are coaxially arranged with the dewatering barrel 400 and fixedly installed in the dewatering barrel 400, the plurality of blocking rings 411 are uniformly distributed along the axis of the dewatering barrel 400, the height of the blocking rings 411 along the radial direction of the dewatering barrel 400 from the left end to the right end of the dewatering barrel 400 is gradually reduced, and the blocking rings 411 are used for enabling filter residues higher than the blocking rings 411 to move leftwards under the impact of the solution only so that the filter residues cannot be accumulated under the impact of the flow of the solution. The blocking plate 412 is disposed in the dehydration tub 400 and extends toward both ends of the dehydration tub 400 at the inner wall of the dehydration tub 400, and the height of the blocking plate 412 in the radial direction of the dehydration tub 400 gradually becomes smaller from the left end to the right end of the dehydration tub 400.

The air cylinder 150 is in a telescopic barrel shape and is vertically arranged, and the upper end of the air cylinder 150 is communicated with the air pressure pipe 422, so that when the air cylinder 150 contracts, the air cylinder 150 transmits air to the air pressure pipe 422, and the pressure of the air pressure cavity 414 is increased, so that the blocking plate 412 extends out. The support rod 140 is horizontally arranged, one end of the support rod is connected with the support 100, the other end of the support rod is fixedly connected with the lower end of the cylinder 150, and specifically, one end of the support rod 140 is fixedly connected with the charging barrel 120 to play a supporting role. Further, a driving wheel 421 is sleeved on the air pressure pipe 422, and the driving wheel 421 is located outside the dewatering barrel 400, the driving wheel 421 can drive the air pressure pipe 422 to rotate synchronously, the driving wheel 421 is connected with a motor, and the motor drives the driving wheel 421 to rotate.
In this embodiment, as shown in fig. 2 to 5, two lifting frames 300 are disposed on the support 100, the two lifting frames 300 are respectively disposed at two ends of the dewatering barrel 400, and the dewatering barrel 400 is disposed on the two lifting frames 300, so that the dewatering barrel 400 can slide in a vertical direction on the support 100, specifically, lifting grooves 110 are disposed on end surfaces of left and right ends of the charging barrel 120, and the lifting frames 300 are mounted in the lifting grooves 110. The lifting frame 300 is connected with the bracket 100 through a unidirectional component, so that the dewatering barrel 400 only slides downwards, the unidirectional component comprises a first ratchet bar 310 and a second ratchet bar, and the first ratchet bar 310 is fixed on the upper plate body 320; the second ratchet bar is fixed on the bracket 100, in particular, the second ratchet bar is arranged in the lifting groove 110 and meshed with the first ratchet bar 310; the first ratchet bar 310 can slide down along the second ratchet bar, in particular, the first ratchet bar 310 is not engaged with the second ratchet bar in the initial state, and after the solution in the dewatering tub 400 is filtered, the first ratchet bar 310 is opened to engage with the second ratchet bar, so as to prevent the descending distance of the dewatering tub 400 from being influenced by the gravity of the solution. The lifting frame 300 comprises a pressure spring 330, an upper plate 320 and a lower plate 340; the lower plate 340 is fixedly arranged on the bracket 100; the upper plate 320 is connected with the dehydration tub 400; the compression spring 330 is vertically arranged between the upper plate 320 and the lower plate 340, the upper end of the compression spring is fixedly connected with the upper plate 320, and the lower end of the compression spring is fixedly connected with the lower plate 340.
In operation, one side of the dewatering tub 400 parallel to the horizontal direction is rotated to the lower side, and the solution containing the residue is introduced into the dewatering tub 400 through the feed hopper. The solution flows into the cartridge 120 through the filter screen on the dewatering tub 400, and is finally discharged and collected through the discharge tub 120 on the cartridge 120.
When the solution flows in the dewatering barrel 400, the solution flows from left to right and drives the filter residue to flow along with the solution, the filter residue is pushed to the right by the solution, the filter residue with small particle size is pushed by the solution to a far distance, the filter residue with large particle size is pushed by the solution to a near distance, the filter residue is spread on the horizontal plane in the dewatering barrel 400, the particle size of the filter residue gradually becomes smaller from left to right, and the solution flows outwards from the dewatering barrel 400 and simultaneously causes the lower part and the upper part of the particle size of the filter residue in the same radial direction.
After the filter residue containing the solution is filtered, the one-way assembly is opened at the same time, the dewatering drum 400 slides downwards under the action of the gravity of the filter residue, the lifting frame 300 contracts, and the dewatering drum 400 does not move upwards due to the cooperation of the first ratchet teeth and the second ratchet teeth on the one-way assembly. When the dewatering tub 400 moves downward, the cylinder 150 is contracted by pressure, and the cylinder 150 supplies air into the air inlet pipe and increases the pressure in the air pressure chamber 414 through the air pipe 413. The plurality of blocking plates 412 protrude in a radial direction of the dehydration tub 400 under the pushing of pressure.
Rotating the dehydration barrel 400 by 180 degrees makes the conical surface of the dehydration barrel 400 rotate to the lower end, and filter residues are spread out along the circumferential direction under the action of the blocking plate 412 in the rotating process. Because the conical surface of the dewatering barrel 400 is higher on the left and right bottoms, when the filter residues are stacked to a height higher than that of the blocking ring 411, the part of the filter residues higher than the blocking ring 411 slides to the right end of the dewatering barrel 400, so that the filter residues at the position where the filter residues are stacked are further flattened.
Starting the motor, the motor drives the dewatering barrel 400 to rotate, the centrifugal force of the dewatering barrel 400 which is stressed by the filter residue at the right end of the dewatering barrel 400 is larger, so that the centrifugal force of the filter residue with smaller particle size is larger when the dewatering barrel 400 rotates, the filter residues with different particle sizes correspond to different centrifugal forces, and the dewatering efficiency of the filter residue is improved.
The foregoing description of the preferred embodiments of the invention is not intended to be limiting, but rather is intended to cover all modifications, equivalents, alternatives, and improvements that fall within the spirit and scope of the invention.
