Existing proppant dewatering devices have unsatisfactory dewatering effects and lack convenience, with slow dewatering speed of inner layer mud, making it difficult to maintain consistent dewatering.
The filter cartridge is rotated by a dewatering plate for independent dewatering. Combined with the downward pressure of the pressure plate and the discharge of mud by the spiral blades, the dewatering process is accelerated by centrifugal force and gas injection, avoiding mud accumulation and blockage.
It improves the dewatering rate and consistency of the proppant, ensuring that the slurry is discharged from the unit quickly and effectively.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of proppant processing technology, specifically a mud dewatering device for proppant processing. Background Technology
[0002] Proppant is made from natural sand or artificial high-strength ceramic particles with a certain particle size and gradation, using bauxite as raw material, through powder granulation and sintering. Proppant is a key material in fracturing operations. During the processing of proppant, a dewatering device is required to filter and dewater the proppant mud.
[0003] The announcement number is CN220237925U, which discloses "a proppant slurry dewatering device, belonging to the field of proppant dewatering technology, which addresses the problems of unsatisfactory dewatering effect and insufficient ease of use of the dewatering device. It includes a dewatering frame, a dewatering groove inside the dewatering frame, a fixed frame fixed at the middle of the lower end of the dewatering frame, a stepper motor fixed at the middle of the fixed frame, a fixed plate fixed at the drive end of the stepper motor, fixed rods fixed on both sides of the fixed plate, a loading barrel provided on the outer surface of the two fixed rods, two limiting holes opened at the lower end of the loading barrel, and a groove opened at the upper end of the dewatering frame, with several limiting frames slidably connected to the inner wall of the groove".
[0004] There are still some drawbacks in its use. By rotating the loading bucket, the water in the proppant is thrown out under the action of centrifugal force. The water in the inner layer of proppant needs to penetrate through the outer layer of proppant to be discharged. The dewatering speed of the inner layer of mud is relatively slow, and it is not easy to maintain the consistency of dewatering, resulting in a slow dewatering rate of proppant. Utility Model Content
[0005] The purpose of this invention is to provide a mud dewatering device for proppant processing to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution:
[0007] A mud dewatering device for proppant processing, comprising:
[0008] The container body has multiple support legs fixedly installed at equal angles on its outer surface, and a base plate is fixedly connected between the multiple support legs.
[0009] A dehydration assembly is movably installed inside the chamber. The dehydration assembly includes a dehydration plate. Multiple filter cartridges are fixedly installed on the upper surface of the dehydration plate. A water-blocking ring is fixedly installed on the upper surface of the dehydration plate outside the filter cartridges. Multiple pressure plates are movably installed on the inner side of the filter cartridges. A pusher frame is fixedly connected to the upper end of the multiple pressure plates.
[0010] The feeding assembly is fixedly installed on the lower surface of the dewatering plate;
[0011] The feeding assembly is fixedly installed on the upper surface of the silo body.
[0012] Furthermore, a drain pipe is fixedly embedded in the lower surface of the base plate, a discharge pipe is fixedly embedded in the outer surface of the base plate, and a No. 1 motor capable of driving the dewatering plate to rotate is fixedly installed in the lower surface of the base plate.
[0013] Furthermore, a rack is fixedly installed on the upper surface of the chamber body, the rack slides through the push frame, a second motor is fixedly installed on the upper surface of the push frame, and a gear that meshes and drives with the rack is fixedly installed at the output end of the second motor.
[0014] Furthermore, the feeding assembly includes:
[0015] The feed pipe is fixedly connected to the lower surface of the dewatering plate;
[0016] The spiral blades are rotatably connected inside the feed pipe.
[0017] Preferably, a No. 3 motor capable of driving the spiral blades to rotate is fixedly installed at one end of the feeding pipe.
[0018] Furthermore, the feeding assembly includes:
[0019] A multi-port feeding pipe is fixedly installed on the upper surface of the silo body;
[0020] Multiple telescopic tubes are fixedly connected inside the multi-port feeding pipe, and one end of each tube is fixedly connected to the pressure plate.
[0021] Multiple piston plates are slidably connected inside the multi-channel feeding pipe;
[0022] The air pump is fixedly installed on the outer surface of the chamber.
[0023] Preferably, one end of the air pump is fixedly connected to a multi-port hose, the multi-port hose is fixedly connected to a multi-piston plate, a connecting frame is fixedly connected to the upper surface of the multi-piston plate, an electric push rod is fixedly installed on the outer surface of the multi-port feeding pipe, and the output end of the electric push rod is fixedly connected to the connecting frame.
[0024] Compared with the prior art, the beneficial effects of this utility model are:
[0025] 1. The operation of motor one drives the dewatering plate to rotate, dewatering the slurry inside the filter cartridge. Multiple filter cartridges separate the slurry into multiple independent spaces for individual dewatering, reducing the thickness of the slurry accumulated on the surface of the filter cartridge. This reduces the thickness of a single layer of slurry, thus accelerating the dewatering speed. The operation of motor two causes the pusher frame to move downward, driving multiple pressure plates to move downward, squeezing the slurry inside the filter cartridge and disrupting it. After the pressure plates move upward, the slurry re-adheres to the surface of the filter cartridge under centrifugal force. This causes the slurry to move downward and mix, while adjusting the position of the slurry, accelerating the dewatering speed, maintaining the consistency of dewatering, and improving the dewatering rate of the proppant.
[0026] 2. After the mud dewatering is completed, water flows from the drain hole of the dewatering plate into the bottom plate and then is discharged from the drain pipe. The pressure plate continues to move down, squeezing the mud. At this time, the discharge end of the feed pipe is located above the discharge pipe. Motor No. 3 runs, driving the spiral blades to rotate and quickly discharge the mud.
[0027] 3. After feeding is completed, the electric push rod retracts, driving multiple piston plates to move down and block the multi-port feeding pipe. The air pump runs, pumping air into the telescopic pipe and the inside of the filter cylinder. The continuous injection of air accelerates the inflow of water in the mud. At the same time, when the pressure plate squeezes the mud after dewatering, air is injected into the telescopic pipe to prevent mud from entering the telescopic pipe and to allow the mud to be discharged smoothly.

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0035] Please see Figures 1-5 In this embodiment of the present invention, a mud dewatering device for proppant processing includes a bin body 1, with multiple support legs 102 fixedly installed at equal angles on the outer surface of the bin body 1, and a base plate 101 fixedly connected between the multiple support legs 102. A dewatering component 2 is movably disposed inside the bin body 1. The dewatering component 2 includes a dewatering plate 201, with multiple filter cartridges 202 fixedly installed on the upper surface of the dewatering plate 201. A water-blocking ring 203 is fixedly installed on the upper surface of the dewatering plate 201 outside the filter cartridges 202. Multiple pressure plates 204 are movably disposed on the inner side of the filter cartridges 202. A pusher frame 205 is fixedly connected to the upper end of the multiple pressure plates 204. A feeding component 3 is fixedly installed on the lower surface of the dewatering plate 201, and a feeding component 4 is fixedly installed on the upper surface of the bin body 1.
[0036] Specifically, the feeding component 4 discharges the slurry into the dewatering component 2, the dewatering component 2 divides the slurry into multiple independent spaces for dewatering, and the discharging component 3 discharges the dewatered slurry.
[0037] Example 1
[0038] like Figures 1-3As shown, in this embodiment, a drain pipe 103 is fixedly embedded in the lower surface of the base plate 101, a discharge pipe 104 is fixedly embedded in the outer surface of the base plate 101, and a first motor 105 capable of driving the dewatering plate 201 to rotate is fixedly installed in the lower surface of the base plate 101; a rack 206 is fixedly installed in the upper surface of the silo body 1, the rack 206 slides through the push frame 205, a second motor 207 is fixedly installed in the upper surface of the push frame 205, and a gear 208 that meshes and drives the rack 206 is fixedly installed in the output end of the second motor 207.
[0039] In this embodiment, motor 105 operates, driving dewatering plate 201 to rotate, thus dewatering the slurry inside filter cartridge 202. Multiple filter cartridges 202 separate the slurry into multiple independent spaces for individual dewatering, reducing the thickness of the slurry accumulated on the surface of filter cartridge 202. This reduces the thickness of a single layer of slurry, thereby accelerating the dewatering speed. Motor 207 operates, driving gear 208 to rotate on the surface of rack 206, causing pusher frame 205 to move downward, which in turn causes multiple pressure plates 204 to move downward, squeezing the slurry inside filter cartridge 202. The baffle below the pressure plate 204, combined with the rotation of the slurry, disrupts the slurry. After the pressure plate 204 moves upward, the slurry re-adheres to the surface of filter cartridge 202 under centrifugal force. This causes the slurry to move downward and mix, while simultaneously adjusting the position of the slurry, accelerating the dewatering speed, maintaining the consistency of dewatering, and improving the dewatering rate of the proppant.
[0040] like Figure 4 As shown, in this embodiment, the feeding assembly 3 includes: a feeding pipe 301 fixedly connected to the lower surface of the dewatering plate 201, and a spiral blade 302 rotatably connected to the inside of the feeding pipe 301; a No. 3 motor 303 capable of driving the spiral blade 302 to rotate is fixedly installed at one end of the feeding pipe 301.
[0041] In practice, after the mud dewatering is completed, water flows from the drain hole of the dewatering plate 201 into the interior of the bottom plate 101, and then is discharged from the drain pipe 103. The pressure plate 204 continues to move down, squeezing the mud. At this time, the discharge end of the feed pipe 301 is located above the discharge pipe 104. The No. 3 motor 303 runs, driving the spiral blade 302 to rotate and quickly discharge the mud.
[0042] Example 2
[0043] Based on Example 1, in order to compensate for the problem that mud easily enters the interior of the telescopic pipe 402 during material discharge.
[0044] like Figure 1 and 5As shown, in this embodiment, the feeding assembly 4 includes: a multi-port feeding pipe 401 fixedly installed on the upper surface of the hopper 1; multiple telescopic pipes 402 fixedly connected to the inside of the multi-port feeding pipe 401, with one end of each pipe fixedly connected to the pressure plate 204; multiple piston plates 403 slidably connected to the inside of the multi-port feeding pipe 401; and an air pump 406 fixedly installed on the outer surface of the hopper 1. One end of the air pump 406 is fixedly connected to a multi-port hose 407, which is fixedly connected to multiple piston plates 403. A connecting frame 404 is fixedly connected to the upper surface of the multiple piston plates 403. An electric push rod 405 is fixedly installed on the outer surface of the multi-port feeding pipe 401, and the output end of the electric push rod 405 is fixedly connected to the connecting frame 404.
[0045] In practice, the slurry is discharged into the inner side of multiple filter cylinders 202 through the multi-port feeding pipe 401 and the telescopic pipe 402 respectively. The telescopic pipe 402 adapts to the up and down movement of the pressure plate 204. After feeding is completed, the electric push rod 405 retracts, driving multiple piston plates 403 to move down and block the multi-port feeding pipe 401. The air pump 406 operates, pumping air into the telescopic pipe 402 and the inner side of the filter cylinder 202. The continuous injection of air accelerates the inflow of water in the slurry. At the same time, when the pressure plate 204 squeezes the slurry after dewatering, air is injected into the telescopic pipe 402 to prevent the slurry from entering the telescopic pipe 402, so that the slurry can be discharged smoothly.
