Description

Technical Field

[0001] This utility model relates to the field of grinding equipment technology, specifically to a polyacrylamide particle grinding equipment. Background Technology

[0002] Polyacrylamide is a general term for polymers obtained by copolymerizing acrylamide or other monomers. It is one of the most widely used water-soluble polymers. Polyacrylamide is a white powder or small granules. When using polyacrylamide, a grinding device is generally required to grind the polyacrylamide particles into powder. Currently, in existing polyacrylamide granule grinding devices, the filtered polyacrylamide particles usually need to be manually added to the grinding drum for grinding, which is time-consuming and labor-intensive. Moreover, during feeding, the particles are usually directly fed through a feed pipe, causing them to accumulate inside the grinding drum, resulting in a significant reduction in grinding efficiency.

[0003] In the process of realizing this utility model, the inventors found that the following problems in the prior art have not been solved: the existing polyacrylamide particle grinding device does not have the corresponding secondary grinding function for recycled materials. During the grinding process, unqualified large particles need to be manually screened by the staff before being fed into the device. This method is time-consuming and labor-intensive and urgently needs to be improved. Therefore, we propose a polyacrylamide particle grinding device. Utility Model Content

[0004] The purpose of this invention is to provide a polyacrylamide particle grinding device, which solves the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a polyacrylamide particle grinding device, comprising a grinding mill body, a slag pump fixedly installed on one side of the grinding mill body, and two sets of side plates placed at the bottom of the grinding mill body.

[0006] A guide plate is placed at the bottom of the side plate, and support rods are fixedly installed at the four corners of the bottom of the grinding machine body. The support rods are fixedly inserted through the side plate, and the bottom ends of the support rods are fixedly connected to the guide plate.

[0007] A frame is installed between the two sets of side plates, a filter screen is fixedly installed inside the frame, and a storage hopper is fixedly installed at one end of the side plate, with the side of the storage hopper facing the side plate being open.

[0008] The top of the slag pump is integrally formed with a return pipe that extends to the top of the grinding mill body. The bottom of the slag pump is integrally formed with a suction pipe that extends to the storage hopper.

[0009] The grinding mill body has an integrally formed top with a feeding hopper. The bottom of the grinding mill body has a discharge port located directly above the center of the filter screen. Support rods are fixedly installed on both sides of the bottom of the front and rear walls of the grinding mill body. These components, including a slag pump, suction pipe, and filter screen, work together to allow material to slide down into the storage hopper via the inclined filter screen during grinding. During this sliding process, large particles are filtered out by the filter screen, allowing qualified material to fall. Whenever a large amount of material accumulates in the storage hopper, the slag pump is activated, and in conjunction with the suction pipe and return pipe, unqualified material can be re-added into the device. This structural design effectively improves processing efficiency.

[0010] As an optional solution to the technical solution of this application, a bolt is movably inserted through the inner side of the side plate near the support rod. The inner end of the bolt is screwed into the pre-set threaded groove on the frame through the external thread. The bolt and threaded groove and other components can be used together. According to the material powder processing requirements, the bolt can be rotated to separate the bolt from the threaded groove, and the frame can be disassembled and replaced with a frame that is compatible with the filter screen. This detachable assembly meets different processing requirements and is convenient for later cleaning, with a more ideal performance.

[0011] As an optional solution to the technical solution of this application, the side plate has a groove on the outer side near the bolt, and the end of the bolt is completely located in the groove. The bolt end can be accommodated by the groove to prevent it from protruding and scratching foreign objects or personnel.

[0012] As an optional solution to the technical solution of this application, an indicator sign is fixedly installed on the side of the front wall of the grinding machine body near the support rod, and the indicator sign is fixed by welding. The guide text on the indicator sign can inform the operator of the corresponding procedures, making it easy to understand and use.

[0013] As an optional solution to the technical solution of this application, a viewing window is integrally formed on one side of the front wall of the storage hopper, and scale lines are adhered on the viewing window. The amount of material in the hopper can be known through the viewing window and the scale lines, which facilitates timely processing.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] 1. This utility model discloses a polyacrylamide particle grinding device, which is equipped with a slag pump, a suction pipe, and a filter screen. During the operation of the grinding device, the material falling into the storage hopper can be conveyed through the inclined filter screen. During the material conveying, the material that is too large is filtered by the filter screen, allowing qualified material to fall. Whenever there is a large amount of material stored in the storage hopper, the slag pump is started, and in conjunction with the suction pipe and the return pipe, the unqualified material can be added back into the device. This structural design effectively improves the processing efficiency.

[0016] 2. The present invention relates to a polyacrylamide particle grinding device, which is equipped with bolts and threaded grooves. According to the material powder processing requirements, the bolts can be rotated to separate the bolts from the threaded grooves, and the frame can be disassembled and replaced with a frame that is compatible with the filter screen. This detachable assembly meets different processing requirements and is also convenient for later cleaning, resulting in a more ideal performance. Attached Figure Description

[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] Please see Figure 1-3This utility model provides a technical solution: a polyacrylamide particle grinding device, including a grinding mill body 1, a slag pump 2 fixedly installed on one side of the grinding mill body 1, two sets of side plates 3 placed at an angle at the bottom of the grinding mill body 1, a guide plate 4 placed at the bottom of the side plate 3, and support rods 41 fixedly installed at the four corners of the bottom of the grinding mill body 1, the support rods 41 respectively fixedly passing through the side plates 3, and the bottom ends of the support rods 41 fixedly connected to the guide plates 4; a frame 5 is installed between the two sets of side plates 3, a filter screen 51 is fixedly installed inside the frame 5, a storage hopper 31 is fixedly installed at one end of the side plate 3, and the side of the storage hopper 31 facing the side plate 3 is open; a return pipe 21 is integrally formed on the top of the slag pump 2, and the return pipe 21 extends to the top of the grinding mill body 1. The bottom of the slag pump 2 is integrally formed with a suction pipe 22, the bottom end of which extends into the storage hopper 31. A viewing window is integrally formed on one side of the front wall of the storage hopper 31, and scale lines are adhered to the viewing window. The amount of material in the hopper can be known through the viewing window and the scale lines, which is convenient for timely processing. The top of the grinding machine body 1 is integrally formed with a feeding hopper 12. The bottom of the grinding machine body 1 is installed with a discharge port 13 on the upper side of the middle of the filter screen 51. Support rods 14 are fixedly installed on both sides of the bottom of the front and rear walls of the grinding machine body 1. An indicator sign 11 is fixedly installed on the side of the front wall of the grinding machine body 1 near the support rod 14. The indicator sign 11 is fixed by welding. The guide text on the indicator sign 11 can inform the operator of the corresponding procedures, which is convenient for understanding and use.

[0024] In this technical solution, components such as the slag pump 2, suction pipe 22, and filter screen 51 can be used together. During the operation of the grinding device, the material falling into the storage hopper 31 can be conveyed through the inclined filter screen 51. During the material conveying, large particles of material are filtered through the filter screen 51, allowing qualified material to fall. Whenever a large amount of material is stored in the storage hopper 31, the slag pump 2 is started, and in conjunction with the suction pipe 22 and return pipe 21, unqualified material can be added back into the device. This structural design effectively improves processing efficiency.

[0025] In some technical solutions, a bolt 33 is movably inserted through the inner side of the side plate 3 near the support rod 14, and a groove 32 is provided on the outer side of the side plate 3 near the bolt 33, and the end of the bolt 33 is completely located in the groove 32. The end of the bolt 33 can be stored in the groove 32 to prevent it from protruding outward and scratching foreign objects or personnel. The inner end of the bolt 33 is screwed into the pre-set threaded groove 52 on the frame 5 through the external thread.

[0026] In this technical solution, components such as bolts 33 and threaded grooves 52 can be used together. According to the material powder processing requirements, bolts 33 can be rotated to separate them from threaded grooves 52, and frame 5 can be disassembled and replaced with a frame 5 that is compatible with filter screen 51. This detachable assembly meets different processing requirements and is easy to clean later, with a relatively ideal effect.

[0027] Working principle: It should be noted that this utility model is a polyacrylamide particle grinding device. All components are general standard parts or parts known to those skilled in the art. Its structure and principle can be learned by those skilled in the art through technical manuals or conventional test methods.

[0028] When a polyacrylamide granule grinding device is used, the grinding device is transported to a designated area, then the device is powered by an external power source and fixed by a support rod 14. During this process, polyacrylamide granules are added into the feeding hopper 12, and after being ground by the grinding mechanism, they are discharged from the discharge port 13 for polyacrylamide granule grinding processing.

[0029] By incorporating a slag pump 2, a suction pipe 22, and a filter screen 51, the grinding device allows materials to slide down towards the storage hopper 31 via the inclined filter screen 51. During this sliding process, large particles are filtered out by the filter screen 51, allowing qualified materials to fall. Whenever a large amount of material accumulates in the storage hopper 31, the slag pump 2 is activated, working in conjunction with the suction pipe 22 and the return pipe 21 to allow unqualified materials to be reintroduced into the device. This structural design effectively improves processing efficiency. Furthermore, by incorporating bolts 33 and threaded grooves 52, the bolts 33 can be rotated to separate from the threaded grooves 52, allowing the frame 5 to be disassembled and replaced with a frame 5 adapted to the filter screen 51, according to the material processing requirements. This detachable assembly meets different processing requirements and facilitates subsequent cleaning, resulting in a satisfactory performance.
