Description

Technical Field

[0001] The utility model relates to the technical field of polyacrylamide grinding, in particular to a grinding device for polyacrylamide processing which is convenient for collection. Background Art

[0002] Currently, polyacrylamide is a linear polymer that is a hard, glassy solid at room temperature. Its products include glue, latex, white powder, translucent beads, and flakes. It has excellent thermal stability and is soluble in water at any ratio. Its aqueous solution is a uniform, transparent liquid. After long-term storage, the polymer slowly degrades, causing the solution viscosity to decrease, especially under poor storage and transportation conditions. Polyacrylamide is widely used as a lubricant, suspending agent, clay stabilizer, oil displacement agent, fluid loss additive, and thickener in drilling, acidizing, fracturing, water plugging, cementing, and secondary and tertiary oil recovery. It is an extremely important oilfield chemical.

[0003] Among them, the processing steps of polyacrylamide mainly include batching, polymerization, granulation, drying, post-processing, crushing and packaging. Crushing and packaging: the qualified polyacrylamide particles that have passed the screening are crushed to the required fineness, and are packed into bags or barrels according to specifications and sealed for storage, ready for factory sale or use.

[0004] In the market, when grinding polyacrylamide, most of the methods are to grind it for a long time through a grinder. However, the grinder can only grind polyacrylamide through a single grinding disc, with limited grinding efficiency and difficulty in automatic feeding and discharging. Therefore, a new technical solution needs to be designed to solve the problem, which can grind polyacrylamide efficiently and collect the ground polyacrylamide at the same time. Utility Model Content

[0005] The purpose of the utility model is to provide a grinding device for polyacrylamide processing which is convenient for collection, and solves the problems raised in the background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a grinding device for processing polyacrylamide that is easy to collect, comprising a base, a mounting frame fixedly mounted on the top of the base, slideways fixedly mounted on both sides of the top of the mounting frame, sliders slidably mounted in two groups of the slideways, limiting rods fixedly mounted on the side walls of the two groups of sliders, multiple groups of equally spaced connecting frames fixedly mounted on the bottom of the limiting rods, a grinding box fixedly mounted on the other end of each group of connecting frames, a tooth plate fixedly mounted in the middle of the top of the limiting rods, a driving arm rotatably mounted on the top of the mounting frame via a rotating shaft, and a driving mechanism mounted on the driving arm;

[0007] The driving mechanism includes a limiting groove opened in the middle of the driving arm, a limiting block slidably installed in the limiting groove, arc-shaped teeth fixedly installed at the bottom of the driving arm, and an eccentric disk rotatably installed on one side of the mounting frame.

[0008] As an optional solution of the technical solution of the present application, the outer side of the eccentric disk is fixedly mounted on the side wall of the limit block, the arc-shaped teeth are engaged with the tooth plate, and the central axis of the eccentric disk is fixedly mounted on the motor shaft.

[0009] As an optional solution of the technical solution of the present application, a filter cartridge is fixedly installed inside each group of the grinding boxes through a bracket, and grinding balls are movably installed inside the filter cartridge to grind the polyacrylamide inside the grinding box.

[0010] As an optional solution of the technical solution of the present application, a cover is threadedly installed at one end of each group of grinding boxes, and a one-way valve is fixedly installed in the middle of one side of the cover to facilitate the introduction of air into the interior of the grinding box.

[0011] As an optional solution of the technical solution of the present application, the side walls of each group of filter cartridges are connected and installed with a feeding pipe, and the bottom end of each group of grinding boxes is connected and installed with a discharge pipe to facilitate the transportation of polyacrylamide materials.

[0012] As an optional solution to the technical solution of the present application, a raw material box is fixedly installed on the top of the side wall of the mounting frame, and a recovery box is fixedly installed on one side of the top of the base. Pump bodies are installed inside the raw material box and the recovery box, and the two groups of pump body ports are respectively connected to the corresponding feeding pipes and discharge pipes, so that the ground polyacrylamide can be recovered.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0014] 1. The technical solution of the present application drives the eccentric disk in the driving mechanism to rotate through a driving motor, and the limit block located on the outside will follow the eccentric disk to make circular motion. Since the limit block is slidably connected to the upper limit groove of the driving arm, it can drive the driving arm to swing back and forth along the rotating shaft, and cooperate with the arc-shaped teeth at the bottom of the driving arm to engage with the tooth plate, and efficiently and synchronously drive the limit rod at the bottom of the tooth plate to move horizontally along the two sets of slides, so that multiple groups of grinding boxes can move back and forth horizontally following the limit rod, ensuring that the grinding balls inside each group of grinding boxes can grind polyacrylamide reciprocatingly, thereby greatly improving the grinding efficiency.

[0015] 2. The technical solution of the present application is that each group of grinding boxes is fixedly installed with a filter cartridge through a bracket, and grinding balls are movably installed inside the filter cartridge. When the polyacrylamide inside the raw material box is continuously introduced into the filter cartridge through the feeding tube, the reciprocating swinging grinding box will drive the grinding balls to roll left and right to grind the polyacrylamide inside the filter cartridge. The ground polyacrylamide will fall through the filter holes on the filter cartridge. When the pump body inside the recovery box is driven, the ground polyacrylamide inside the grinding box can be recovered, and the ground polyacrylamide can be efficiently recovered.

DETAILED DESCRIPTION

[0020] See also Figure 1-2 The utility model provides a technical solution: a grinding device for polyacrylamide processing that is easy to collect, comprising a base 1, a mounting frame 11 is fixedly mounted on the top of the base 1, slideways 2 are fixedly mounted on both sides of the top of the mounting frame 11, sliders are slidably mounted in the two sets of slideways 2, limiting rods 21 are fixedly mounted on the side walls of the two sets of sliders, a plurality of groups of equally spaced connecting frames 22 are fixedly mounted on the bottom of the limiting rods 21, a grinding box 23 is fixedly mounted on the other end of each group of connecting frames 22, a tooth plate 24 is fixedly mounted in the middle of the top of the limiting rod 21, a driving arm 25 is rotatably mounted on the top of the mounting frame 11 through a rotating shaft, and a driving mechanism is mounted on the driving arm 25;

[0021] The driving mechanism includes a limit groove 26 opened in the middle of the driving arm 25, a limit block 27 slidably installed in the limit groove 26, an arc-shaped tooth 28 fixedly installed at the bottom of the driving arm 25, and an eccentric disk 29 rotatably installed on one side of the mounting frame 11. The outer side of the eccentric disk 29 is fixedly installed on the side wall of the limit block 27, the arc-shaped tooth 28 is engaged with the tooth plate 24, and the central axis of the eccentric disk 29 is fixedly installed on the motor shaft.

[0022] In this technical solution, by driving the motor and driving the eccentric disk 29 in the driving mechanism to rotate, the limit block 27 located on the outside will follow the eccentric disk 29 to make circular motion. Since the limit block 27 is slidably connected to the upper limit groove 26 on the driving arm 25, it can drive the driving arm 25 to swing back and forth along the rotating shaft, and cooperate with the arc-shaped teeth 28 at the bottom of the driving arm 25 to engage with the tooth plate 24, and efficiently and synchronously drive the limit rod 21 at the bottom of the tooth plate 24 to move horizontally along the two groups of slides 2, so that multiple groups of grinding boxes 23 can follow the limit rod 21 to move back and forth in the horizontal direction, ensuring that the grinding balls 31 inside each group of grinding boxes 23 can reciprocate to grind polyacrylamide, thereby greatly improving the grinding efficiency.

[0023] In some technical solutions, a filter cartridge 3 is fixedly installed inside each group of grinding boxes 23 through a bracket, and a grinding ball 31 is movably installed inside the filter cartridge 3 to grind the polyacrylamide inside the grinding box 23.

[0024] In this technical solution, when the polyacrylamide inside the raw material box 12 is continuously introduced into the filter cartridge 3 through the feeding tube 34, the reciprocating grinding box 23 will drive the grinding balls 31 to roll left and right to grind the polyacrylamide inside the filter cartridge 3. The ground polyacrylamide will fall through the filter holes on the filter cartridge 3. When the pump body inside the recovery box 13 is driven, the ground polyacrylamide inside the grinding box 23 can be recovered, and the ground polyacrylamide can be efficiently recovered.

[0025] In some technical solutions, the side walls of each group of filter cartridges 3 are connected and installed with a feeding pipe 34, and the bottom end of each group of grinding boxes 23 is connected and installed with a discharge pipe 35, which is convenient for conveying polyacrylamide materials. The top of the side wall of the mounting frame 11 is fixedly installed with a raw material box 12, and the top side of the base 1 is fixedly installed with a recovery box 13. Pump bodies are installed inside the raw material box 12 and the recovery box 13. The two groups of pump body ports are connected and installed with the corresponding feeding pipe 34 and discharge pipe 35 respectively, so that the ground polyacrylamide can be recovered.

[0026] In this technical solution, the pump body inside the raw material box 12 is driven to introduce a certain amount of polyacrylamide raw material into multiple groups of grinding boxes 23, waiting for the multiple groups of grinding boxes 23 to efficiently grind the polyacrylamide. Conversely, the pump body inside the recovery box 13 is driven to recycle the ground polyacrylamide inside the grinding box 23, and the ground polyacrylamide can be efficiently recycled.

[0027] In some technical solutions, a cover 32 is threadedly installed at one end of each group of grinding boxes 23, and a one-way valve 33 is fixedly installed in the middle of one side of the cover 32 to facilitate the introduction of air into the grinding box 23.

[0028] In this technical solution, when the pump body inside the recovery box 13 is driven to recover the ground polyacrylamide inside the grinding box 23, negative pressure will be delivered to the inside of the grinding box 23, and the one-way valve 33 installed on the cover 32 will facilitate the introduction of air into the grinding box 23 and the recovery of the ground polyacrylamide.

[0029] When using a grinding device for processing polyacrylamide that is easy to collect, it should be noted that the utility model is a grinding device for processing polyacrylamide that is easy to collect, and each component is a universal standard part or a component known to those skilled in the art, and its structure and principle can be known to those skilled in the art through technical manuals or through conventional experimental methods.

[0030] During use, a fixed amount of polyacrylamide raw material is first introduced into the multiple groups of grinding boxes 23 by driving the pump body inside the raw material box 12, and the multiple groups of grinding boxes 23 are left to grind the polyacrylamide efficiently. At the same time, the motor is driven to drive the eccentric disk 29 in the driving mechanism to rotate, and the limit block 27 located on the outside will follow the eccentric disk 29 to make a circular motion. Since the limit block 27 is slidably connected with the upper limit groove 26 on the driving arm 25, the driving arm 25 can be driven to swing back and forth along the rotating shaft, and the arc-shaped teeth 28 at the bottom of the driving arm 25 are engaged with the tooth plate 24, and the limit rod 21 at the bottom of the tooth plate 24 is efficiently and synchronously driven to move horizontally along the two groups of slideways 2, so that the multiple groups of grinding boxes 23 can follow the limit rod 21 to move back and forth horizontally. It ensures that the grinding balls 31 inside each group of grinding boxes 23 can reciprocate to grind the polyacrylamide, which greatly improves the grinding efficiency. At the same time, the filter cartridge 3 is fixedly installed inside each group of grinding boxes 23 through a bracket, and the grinding balls 31 are movably installed inside the filter cartridge 3. When the polyacrylamide inside the raw material box 12 is continuously introduced into the filter cartridge 3 through the feeding pipe 34, the reciprocating grinding box 23 will drive the grinding balls 31 to roll left and right to grind the polyacrylamide inside the filter cartridge 3. The ground polyacrylamide will fall through the filter holes on the filter cartridge 3, and the pump body inside the recovery box 13 will be driven to recover the ground polyacrylamide inside the grinding box 23, so the ground polyacrylamide can be recovered efficiently.
