Description

Technical Field

[0001] This utility model belongs to the field of polyacrylamide processing technology, and in particular relates to a low-temperature cooling device for polyacrylamide. Background Technology

[0002] Drilling fluid is the lifeblood of drilling, and polyacrylamide, as a polymer coating agent, is an important component of polymer drilling fluid. The coating agent can effectively inhibit the hydration and dispersion of drill cuttings and the well wall, thereby maintaining the stability of the well wall. During the drilling process, viscous polyacrylamide molecules can quickly adhere to the surface of drill cuttings and clay, playing a coating and flocculation role, thus preventing clay dispersion, and can also form mud cake on the well wall, which can reduce the transmission pressure difference and filtrate permeation.

[0003] However, polyacrylamide particles used in conventional oilfield drilling fluid systems are prone to clumping during long-term storage. This leads to problems such as slower dissolution rates during use, requiring workers to manually select and break up large pieces in advance, which takes a lot of time, before using the fluid to accelerate dissolution. Therefore, a low-temperature cooling device for polyacrylamide is needed. This device, equipped with components such as a liquid nitrogen tank and movable plates, can automatically break up clumped polyacrylamide during use and reduce its overall temperature to ensure the overall quality of the broken polyacrylamide. Utility Model Content

[0004] The purpose of this invention is to provide a low-temperature cooling device for polyacrylamide, which has the advantages of automatically cooling lumps of polyacrylamide during use, and ensuring the overall quality of the crushed polyacrylamide by reducing its overall temperature, thereby solving the aforementioned technical problems.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A low-temperature cooling device for polyacrylamide includes a support frame, a crushing box is fixedly installed at one end of the support frame, a motor is fixedly installed at one end of the crushing box, a crushing rod is fixedly installed at the output end of the motor, a first helical gear is fixedly installed at one end of the crushing rod, a fixed plate is fixedly installed at one end of the support frame, a reciprocating screw is movably installed inside the fixed plate, a second helical gear meshing with the first helical gear is fixedly installed at one end of the reciprocating screw, a movable block is movably installed at one end of the reciprocating screw, a movable plate is movably installed at one end of the movable block, a sieve plate is fixedly installed inside the crushing box, a conveying hose is detachably installed at one end of the crushing box, and a cooling device for low-temperature treatment of raw materials is fixedly installed at one end of the crushing box.

[0006] Preferably, the cooling device includes a rack, a liquid nitrogen tank, a control valve, a gear, and a pressure gauge. A liquid nitrogen tank is fixedly installed at one end of the pulverizing box, and a control valve is movably installed at one end of the liquid nitrogen tank. A gear is fixedly installed at one end of the control valve, and a rack matching the gear is fixedly installed at one end of the movable block.

[0007] Preferably, a pressure gauge is detachably installed at one end of the liquid nitrogen chamber, and a limiting groove is provided inside the support frame to restrict the movable block.

[0008] Preferably, a rotating shaft is movably mounted at one end of the crushing box, and a cleaning plate is fixedly mounted at one end of the rotating shaft, while a top block is fixedly mounted at one end of the rack.

[0011] The beneficial effects of this utility model are:

[0012] 1. This utility model, by incorporating components such as a crushing rod, a movable plate, a sieve plate, a second helical gear, and a reciprocating screw, allows workers to crush lumps of polyacrylamide simply by starting the motor to control the crushing rod to rotate, breaking down the lumps falling from the conveying hose. This achieves the purpose of crushing polyacrylamide. Simultaneously, the sieve plate effectively separates large pieces of polyacrylamide, preventing substandard polyacrylamide lumps from entering the construction site and affecting the overall work progress. Furthermore, as the crushing rod rotates, the first and second helical gears drive the reciprocating screw to rotate, causing the movable plate to continuously reciprocate. The movable plate then crushes large pieces of polyacrylamide blocked by the sieve plate, ensuring effective crushing.

[0013] 2. This utility model, by incorporating components such as a liquid nitrogen chamber, rotating shaft, top block, gears, and control valves, enables workers to crush polyacrylamide raw materials using this equipment. During its movement, the movable block drives the gears to rotate via a rack and pinion mechanism, thereby controlling the opening and closing of the control valve. This intermittently releases liquid nitrogen into the crushing chamber during the crushing process, lowering the overall internal temperature and making the polyacrylamide raw material more brittle and easier to crush and separate by the crushing rod, ensuring the crushing effect. Simultaneously, the top block intermittently squeezes the cleaning plate, causing its other end to strike the conveying hose, preventing the conveying hose from becoming clogged with raw material.

[0021] In the following description, embodiments of the polyacrylamide cryogenic cooling device of the present invention will be described with reference to the accompanying drawings.

[0022] Figure 1-4This invention illustrates a cryogenic cooling device for polyacrylamide according to an embodiment of the present invention. It includes a support frame 1, with a crushing chamber 2 fixedly mounted at one end of the support frame 1. The cooling device includes a rack 16, a liquid nitrogen tank 18, a control valve 19, a gear 20, and a pressure gauge 21. The liquid nitrogen tank 18 is fixedly mounted at one end of the crushing chamber 2, and the control valve 19 is movably mounted at one end of the liquid nitrogen tank 18. The gear 20 is fixedly mounted at one end of the control valve 19, and a rack 16 matching the gear 20 is fixedly mounted at one end of a movable block 9. The crushing chamber 2 provides support and fixation for the liquid nitrogen tank 18, ensuring that its position does not shift during operation. The movably mounted control valve 19 allows it to rotate inside the liquid nitrogen tank 18, thereby controlling the addition of liquid nitrogen to the crushing chamber 2. The gear 20 and rack 16 at one end of the control valve 19 are matched, so that when the rack 16 contacts the gear 20, it drives the gear 20 to rotate as a whole, thereby ensuring that nitrogen can be intermittently added to the inside of the crushing chamber 2. A motor 3 is fixedly installed at one end of the crushing chamber 2, and a rotating shaft 22 is movably installed at one end of the crushing chamber 2. A cleaning plate 23 is fixedly installed at one end of the rotating shaft 22, and a top block 17 is fixedly installed at one end of the rack 16. The movably installed rotating shaft 22 allows it to rotate inside the crushing chamber 2. The cleaning plate 23 fixedly installed at one end of the shaft 23 will rotate around the rotating shaft 22 when it is squeezed. The top block 17 fixedly installed at one end of the rack 16 will push the cleaning plate 23 through the top block 17 during the movement of the rack 16. The cleaning plate 23 rotates around the rotating shaft 22, thereby controlling the other end of the cleaning plate 23 to strike the conveying hose 26, helping it to discharge materials better. A crushing rod 4 is fixedly installed at the output end of the motor 3, and a first helical gear 5 is fixedly installed at one end of the crushing rod 4. A pressure gauge 21 is detachably installed at one end of the liquid nitrogen tank 18. A limiting groove 10 is opened inside the support frame 1 to restrict the movable block 9. The detachable pressure gauge 21 facilitates subsequent maintenance by workers and allows real-time observation of its internal liquid nitrogen capacity. The limiting groove 10 can effectively restrict the movable block 9, ensuring its direction and distance of movement. A fixing plate 6 is fixedly installed at one end of the support frame 1, and a reciprocating screw 7 is movably installed inside the fixing plate 6. One end of the reciprocating screw 7 is fixedly installed... A second helical gear 8, meshing with the first helical gear 5, is fixedly installed. A movable block 9 is movably installed at one end of the reciprocating screw 7, and a movable plate 12 is movably installed at one end of the movable block 9. A screen plate 13 is fixedly installed inside the crushing box 2. An extension plate 24 is fixedly installed at one end of the crushing box 2, and a spring 25 is fixedly installed at one end of the extension plate 24. The extension plate 24 and the cleaning plate 23 are connected by the spring 25. The crushing box 2 provides support and fixation for the extension plate 24. The connection between the extension plate 24 and the cleaning plate 23 via the spring 25 ensures that after the cleaning plate 23 is no longer squeezed by the top block 17, the spring 25 will control its overall reset, ensuring that it continuously and intermittently taps the conveying hose 26 to prevent the raw material inside from clogging.A conveying hose 26 is detachably installed at one end of the crushing box 2. A cooling device for low-temperature treatment of raw materials is fixedly installed at the other end of the crushing box 2. Multiple sets of baffles 11 are fixedly installed inside the crushing box 2, and a through hole 15 for the movable plate 12 to move is provided inside the crushing box 2. A discharge port 14 is fixedly installed at one end of the crushing box 2, and a placement groove 27 is provided at one end of the support frame 1. The baffles 11 are triangular in shape, which can effectively prevent the movable plate 12 from carrying the raw materials out of the crushing box 2 during movement. The through hole 15 provides space for the movable plate 12 to move inside the crushing box 2. The discharge port 14 can guide the crushed raw materials to better discharge them from the inside of the crushing box 2. The placement groove 27 allows workers to easily fix and restrict the collection bucket, ensuring its stability during the material receiving process.

[0023] Working Principle: When using this invention, the worker places the storage bucket inside the placement slot 27, starts the motor 3, and drives the crushing rod 4 inside the crushing box 2 to rotate. The feeding switch is opened, allowing the polyacrylamide raw material inside the feeding hose 26 to enter the crushing box 2. The crushing rod 4 crushes the lumps of raw material. Simultaneously, during rotation, the crushing rod 4 drives the reciprocating screw 7 to rotate via the second helical gear 8 and the first helical gear 5, causing the movable block 9 to continuously reciprocate within the crushing box 2. The stop block 11 ensures that the movable plate 12 does not carry the raw material out of the crushing box 2 during its movement. Furthermore, during the continuous reciprocating movement of the movable plate 12, any remaining raw material is removed. Large pieces of polyacrylamide blocked at the end face of the sieve plate 13 are broken up, allowing them to pass through the sieve plate 13 and be discharged into the crushing box 2. During the movement of the movable block 9, the rack 16 drives the gear 20 to rotate, causing liquid nitrogen from the liquid nitrogen chamber 18 to intermittently enter the crushing box 2, thereby reducing the overall stability of the raw material and ensuring that the lumps of polyacrylamide raw material can be better broken up and separated. During the movement of the movable block 9, the top block 17 at one end will squeeze the cleaning plate 23, causing the cleaning plate 23 to intermittently knock on the conveying hose 26, effectively preventing the polyacrylamide raw material inside from clogging. Qualified raw material will enter the storage box through the discharge port 14, completing the processing and crushing of the polyacrylamide raw material.

[0024] In summary, this polyacrylamide cryogenic cooling device, equipped with components such as a crushing rod 4, a movable plate 12, a sieve plate 13, a second helical gear 8, and a reciprocating screw 7, allows workers to crush lumps of polyacrylamide simply by starting the motor 3 to control the crushing rod 4 to rotate, breaking down the lumps falling from the conveying hose 26. This achieves the purpose of crushing polyacrylamide. Simultaneously, the sieve plate 13 effectively separates large pieces of polyacrylamide, preventing substandard polyacrylamide lumps from entering the construction site and affecting the overall work progress. Furthermore, when the crushing rod 4 rotates, the first helical gear 5 and the second helical gear 8 drive the reciprocating screw 7 to rotate, causing the movable block 9 to continuously reciprocate the movable plate 12. The movable plate 12 then crushes large pieces of polyacrylamide blocked by the sieve plate 13, ensuring effective crushing.
