Description

Technical Field

[0001] This utility model relates to the field of screening equipment technology, and more specifically, it relates to a screening device for waterproof polymer raw materials. Background Technology

[0002] Waterproofing materials are used in building envelopes to prevent the penetration of rainwater, snowmelt, and groundwater; to prevent the erosion of moisture, vapor, and other harmful gases and liquids in the air; and to prevent the penetration of water supply and drainage systems. These materials, which prevent seepage, leakage, and erosion, are collectively referred to as waterproofing materials. During the production of waterproofing materials, the raw materials used need to be treated to avoid the presence of dust and debris, which could affect the composition of the waterproofing material and prevent it from achieving its desired waterproofing effect.

[0003] Existing screening devices generally involve feeding granular raw materials into a screening machine and using vibration screening to remove impurities carried in the raw materials.

[0004] The existing technical solutions mentioned above have the following drawbacks: they cannot treat the dust carried in the raw materials, resulting in the dust remaining in the raw materials after screening. This affects the waterproofing effect of the waterproofing materials during production. Furthermore, the amount of material put into the screening machine cannot be controlled, causing the raw materials to accumulate on the screening plate and resulting in the incomplete screening of the raw materials being discharged directly from the screening machine.

[0030] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the technical solutions in the specific embodiments of this utility model are clearly and completely described below to further illustrate this utility model. Obviously, the specific embodiments described are only a part of the embodiments of this utility model, and not all of them.

[0031] Example 1:

[0032] This utility model provides a technical solution: a polymer waterproof raw material screening device, including a housing 1 and a processing tank 15, such as... Figure 1 A limiting groove 2 is provided on one side of the box body 1, and a discharge chute 3 is provided on the other side of the box body 1. A swaying screening plate 4 is installed inside the box body 1. A processing box 15 is connected to the top of the box body 1 and communicates with the box body 1. Multiple blowers 17 that can blow air to the other side of the processing box 15 are provided on one side of the inner wall of the processing box 15. A collection box 20 is connected to the other side of the processing box 15. A rotatable first rotating shaft 8 is provided on one side of the box body 1, and the first rotating shaft 8 is located on one side of the screening plate 4. Figure 2 The top of the processing box 15 is connected to a feed hopper 22, and a second rotating shaft 23 that can rotate is provided inside the feed hopper 22. Multiple material distribution plates 24 are connected to the surface of the second rotating shaft 23.

[0033] Specifically, the bottom of the limiting groove 2 is higher than the top of the discharge chute 3. One side of the screening plate 4 is located inside the limiting groove 2, and the other side of the screening plate 4 is located inside the discharge chute 3. The screening plate 4 is inclined from the side closer to the limiting groove 2 to the side closer to the discharge chute 3. A first movable frame 5 is connected to one side of the housing 1, and the first movable frame 5 is located below the limiting groove 2. A second movable frame 6 is connected to the other side of the housing 1, and the second movable frame 6 is located below the discharge chute 3. The first movable frame 5 and the second movable frame 6 are rotatably connected to the bottom sides of the screening plate 4, respectively. A bearing seat 7 is connected to one side of the housing 1, and the bearing seat 7 is located on one side of the first movable frame 5. The first rotating shaft 8 is rotatably connected to... On the bearing housing 7, one end of the first rotating shaft 8 is connected to a first push rod 9, and the other end of the first push rod 9 is rotatably connected to a second push rod 10. The side of the screening plate 4 near the first rotating shaft 8 is connected to a fixed seat 11, and the other end of the second push rod 10 is rotatably connected to the fixed seat 11. The top of the box 1 is connected to an air pump 18, which is located on one side of the processing box 15. The output end of the air pump 18 is connected to a ventilation pipe 19. The inner wall of the processing box 15 is connected to an air volume regulating valve 16. Multiple blowers 17 are all connected to the output end of the air volume regulating valve 16. The other end of the ventilation pipe 19 passes through the processing box 15 and is connected to the input end of the air volume regulating valve 16. By adopting the above technical solution, the screening plate 4 is set in the limiting groove 2 and the discharge groove 3, with the limiting groove 2 being higher than the discharge groove 3, so that the screening plate 4 is tilted from the limiting groove 2 to the discharge groove 3, thereby discharging the unsuitable raw materials and debris in the discharge groove 3. When driven by the belt 30, the first rotating shaft 8 and the second rotating shaft 23 are driven to rotate synchronously. When the first rotating shaft 8 rotates, it drives the second push rod 10 to push, thereby causing the screening plate 4 to shake and perform screening operation on the raw materials. The air pump 18 and the blower head 17 blow air onto the evenly falling raw materials, thereby blowing out the dust carried in the raw materials. The air volume regulating valve 16 is used to adjust the blowing size of the blower head 17 for processing raw materials of different sizes.

[0034] Example 2:

[0035] Based on Example 1.

[0036] Specifically, such as Figure 3 The bottom of the box 1 is connected to a discharge hopper 12, which is semi-circular. The top of the discharge hopper 12 is connected to the bottom of the box 1. An auger 13 is rotatably connected to one side of the inner wall of the discharge hopper 12. The auger 13 is driven by an external motor, which is not shown in the figure. One side of the discharge hopper 12 is open. A storage box 21 is placed on the bottom of the inner wall of the collection box 20. A mounting bracket 14 is connected to the bottom of the box 1. Figure 4The other end of the first rotating shaft 8 is connected to the first drive wheel 25, and the other end of the second rotating shaft 23 passes through the feed hopper 22 and is connected to the second drive wheel 26. The first drive wheel 25 and the second drive wheel 26 are both located on one side of the housing 1. The side of the housing 1 closest to the second drive wheel 26 is connected to the support frame 27. The support frame 27 is connected to the motor 28. The output shaft of the motor 28 is connected to the third drive wheel 29. The third drive wheel 29 is located below the second drive wheel 26. The first drive wheel 25, the second drive wheel 26 and the third drive wheel 29 are on the same plane. The first drive wheel 25, the second drive wheel 26 and the third drive wheel 29 are fitted with the same belt 30. By adopting the above technical solution, the auger 13 rotates in the discharge hopper 12, thereby transmitting and removing the raw materials that have fallen into the discharge hopper 12. The first drive wheel 25, the second drive wheel 26 and the third drive wheel 29 facilitate the synchronous rotation of the first rotating shaft 8 and the second rotating shaft 23, thereby causing the upper material distribution plate 24 to rotate and discharge the material, and the lower screening plate 4 to shake and screen synchronously, resulting in better processing effect.

[0037] The working principle of this utility model is as follows: During use, the operator places the raw material into the feeding hopper 22. The raw material slides downwards within the feeding hopper 22 until it contacts the distribution plate 24. The motor 28 then operates, driving the third drive wheel 29 on the output shaft to rotate. Through the belt 30, the third drive wheel 29 rotates, driving the second drive wheel 26 to rotate. The second drive wheel 26 then drives the second rotating shaft 23 to rotate within the feeding hopper 22, thereby causing the distribution plate 24 to rotate within the feeding hopper 22. The distribution plate 24, connected to the top of the second rotating shaft 23, causes the raw material to rotate within the feeding hopper 22. When the distribution plate 24 rotates below the second rotating shaft 23, the raw material falls off the distribution plate 24 and into the processing box 15. The air pump 18 then operates, causing the raw material to fall into the processing box 15. Air is extracted and channeled through ventilation pipe 19 into airflow regulating valve 16, then sprayed out from blower head 17. Operators can adjust the airflow from blower head 17 via airflow regulating valve 16. Airflow is directed from blower head 17 to the other side of processing box 15, causing dust and debris carried by the raw material to fall as it descends within processing box 15. The blown-out dust and debris enter collection box 20 and, through the limiting mechanism of collection box 20, fall into storage box 21 for easy collection and cleaning by staff. After being treated by the airflow from processing box 15, the raw material falls into box 1 and finally onto screening plate 4. As screening plate 24 rotates continuously, it continuously drives the raw material downwards, thus coordinating with the airflow from blower head 17 and screening plate 4. Plate 4 is used to ensure the material falls evenly, guaranteeing the processing effect of the blower head 17 and the screening effect of the screening plate 4. When the motor 28 is working, it drives the first drive wheel 25 to rotate synchronously through the belt 30. At this time, the first drive wheel 25, the second drive wheel 26, and the third drive wheel 29 rotate synchronously, thereby ensuring the synchronization of the material distribution plate 24 and the screening plate 4 and ensuring screening efficiency. When the first drive wheel 25 rotates, it drives the first rotating shaft 8 to rotate on the bearing seat 7, thereby driving the first push rod 9 to rotate around the first rotating shaft 8 and driving one end of the second push rod 10 to rotate. When the first push rod 9 moves to the side close to the screening plate 4, it will push the screening plate 4. When the 9th shaft moves to the side away from the screening plate 4, it will pull the screening plate 4. Therefore, during the continuous rotation of the first rotating shaft 8, the screening plate 4 will be driven to swing back and forth on the first movable frame 5 and the second movable frame 6, thereby screening the raw materials falling on the screening plate 4. The screening of the raw materials that meet the requirements will fall into the discharge hopper 12. Due to the inclined setting of the screening plate 4, the raw materials that do not meet the requirements and some debris will slide on the screening plate 4 to one side of the discharge chute 3 and slide out through the discharge chute 3, which is convenient for the staff to collect and process again. The raw materials that meet the requirements will fall into the discharge hopper 12. The external motor drives the auger 13 to rotate in the discharge hopper 12, thereby rotating and moving the raw materials out, which is convenient for the staff to carry out subsequent operations.

[0038] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
