Description

Technical Field

[0001] This utility model relates to the field of polyacrylamide production technology, specifically to a high-efficiency moisture-proof screening device for polyacrylamide. Background Technology

[0002] Polyacrylamide (PAM) is a linear polymer with the chemical formula (C3H5NO)n. It is a hard, glassy solid at room temperature, and products include liquids, latexes, white powders, translucent beads, and flakes. It has good thermal stability. It is soluble in water in any proportion, and the aqueous solution is a homogeneous and transparent liquid. Sieving is required during the production of polyacrylamide granules.

[0003] While polypropylene granule screening devices can collect polypropylene granules through sieves, they are not suitable for collecting granules that do not meet requirements. Furthermore, during the screening process, the dried polypropylene granules are prone to re-absorbing moisture, affecting subsequent processing and reducing the efficiency of polypropylene granule production. Therefore, we propose a new high-efficiency moisture-proof screening device for polyacrylamide. Utility Model Content

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0016] Please see Figure 1-3 This utility model provides a technical solution: a high-efficiency moisture-proof sieving device for polyacrylamide, comprising: a box body 1 and a mounting box 2. The mounting box 2 is fixedly connected to the bottom of the box body 1 via a partition plate 4. A through groove 9 is opened on the partition plate 4, and a through groove 10 is opened on one side of the box body 1. A sealing door 13 is provided on one side of the box body 1. Support legs 14 are fixedly connected to the four corners of the bottom of the mounting box 2; a sieving component 3, which is rotatably disposed in the inner cavity of the box body 1; a moisture-proof component 8 and an inclined groove 6. The inclined groove 6 is disposed at the bottom of the partition plate 4, and several through air inlets 15 are evenly opened on both sides of the inclined groove 6. The moisture-proof component 8 is disposed on one side of the bottom of the mounting box 2 and is connected to the inclined groove 6.

[0017] Specifically, such as Figure 3 As shown, the screening assembly 3 includes a motor 3.1, a screening cylinder 3.2, a rotating cylinder 3.3, a fixed cover 3.4, and a handle 3.5. The motor 3.1 is fixedly connected to the side wall of the housing 1. The output end of the motor 3.1 passes through the side wall of the housing 1 and is fixedly connected to the screening cylinder 3.2. The side wall of the screening cylinder 3.2 is evenly provided with several sieve holes to facilitate the screening of polyacrylamide particles. The rotating cylinder 3.3 is fixedly connected to one side of the screening cylinder 3.2. The rotating cylinder 3.3 passes through the second through groove 10 to the outside of the housing 1, and the rotating cylinder 3.3 is rotatably connected to the second through groove 10. The end of the rotating cylinder 3.3 extending out of the outside of the housing 1 is provided with a fixed cover 3.4, and a handle 3.5 is fixedly connected to one side of the fixed cover 3.4. When starting the screening process, open the fixed cover 3.4, put the polyacrylamide particles to be screened into the screening cylinder 3.2 through the rotating drum 3.3, close the fixed cover 3.4, start the motor 3.1, and drive the screening cylinder 3.2 to rotate in the inner cavity of the box 1. This causes the polyacrylamide particles in the screening cylinder 3.2 to tumble and stir continuously, so that polyacrylamide particles of suitable size can fall through the screen holes for screening.

[0018] Specifically, such as Figure 1 , Figure 2 As shown, a filter screen 7 is fixedly attached to the bottom of the inner cavity of the inclined chute 6. After the screening is completed and the screened polyacrylamide particles are dried to prevent moisture, the small polyacrylamide particles in the collection drawer 12 and the excessively large polyacrylamide particles in the screening cylinder 3.2 can be recovered. Then, the filter screen 7 can be removed to collect the polyacrylamide particles in the filter screen 7, thus facilitating the next process. The bottom of the inner cavity of the mounting box 2 is slidably connected to the collection drawer 12, and the collection drawer 12 penetrates through the side wall of the mounting box 2 to the outside. The top of the inclined chute 6 is connected to the through groove 9, and the bottom is connected to the inner cavity of the collection drawer 12. An observation window is opened on the sealing door 13. A ventilation opening 5 is opened on one side of the box body 1, and a ventilation opening 11 is opened on one side of the mounting box 2. Dustproof nets are fixedly connected to the inner cavities of ventilation openings 5 ​​and 11, which can effectively prevent external dust from entering the inner cavity of the box body 1.

[0019] Specifically, such as Figure 3As shown, the moisture-proof component 8 includes a fan 8.1, a heating cylinder 8.2, an air collecting hood 8.3, an air supply hood 8.4, and an exhaust hood 8.5. The fan 8.1 and the heating cylinder 8.2 are respectively fixedly connected to one side of the bottom of the inner cavity of the mounting box 2, and the output end of the fan 8.1 is connected to the heating cylinder 8.2. The air collecting hood 8.3 is fixedly connected to one side of the inclined groove 6. The two air supply hoods 8.4 are respectively fixedly connected to the two sides of the inclined groove 6 with air inlet holes 15. The heating cylinder 8.2, the air collecting hood 8.3, and the air supply hood 8.4 are connected in sequence through pipes. The input end of the fan 8.1 is fixedly connected to the exhaust hood 8.5, and the exhaust hood 8.5 penetrates through the side wall of the mounting box 2 to the outside. During the screening process, the screened polyacrylamide particles fall onto the filter screen 7. The blower 8.1 and the heating cylinder 8.2 are started to draw out the outside air, which is then heated by the heating cylinder 8.2 and introduced into the air collection hood 8.3 through pipes. Finally, the air is introduced into the inner cavity of the air supply hoods 8.4 on both sides and blown onto the polyacrylamide particles in the inclined chute 6 through the air inlet 15. This process can prevent the polyacrylamide particles from getting damp and affecting the next process.

[0020] It should be noted that this utility model is a high-efficiency moisture-proof sieving device for polyacrylamide. When starting the sieving operation, the fixed cover 3.4 is opened, and the polyacrylamide particles to be sieved are placed into the sieving cylinder 3.2 through the rotating drum 3.3. The fixed cover 3.4 is closed, and the motor 3.1 is started, which drives the sieving cylinder 3.2 to rotate in the inner cavity of the box 1, so that the polyacrylamide particles in the sieving cylinder 3.2 are continuously tumbling and stirring, thereby facilitating the falling of polyacrylamide particles of suitable size from the sieve holes for sieving.

[0021] During the screening process, the screened polyacrylamide particles fall onto the filter screen 7. The blower 8.1 and the heating cylinder 8.2 are started to draw out the outside air, which is then heated by the heating cylinder 8.2 and introduced into the air collection hood 8.3 through pipes. Finally, the air is introduced into the inner cavity of the air supply hoods 8.4 on both sides and blown onto the polyacrylamide particles in the inclined chute 6 through the air inlet 15. This process can prevent the polyacrylamide particles from getting damp and affecting the next process.

[0022] After the screening process is completed and the screened polyacrylamide particles are dried to prevent moisture, the small polyacrylamide particles in the collection drawer 12 and the excessively large polyacrylamide particles in the screening cylinder 3.2 can be recovered. Then, the filter screen 7 can be removed to collect the polyacrylamide particles in the filter screen 7, which facilitates the next process.
