Description

Technical Field

[0001] This utility model relates to the field of cleaning screen technology, specifically a cleaning screen with a pressure dispersion structure. Background Technology

[0002] A cleaning screen is a device used for sorting, cleaning, and screening materials. The main function of a cleaning screen is to separate impurities or non-compliant particles from materials through a screen, thereby obtaining the required qualified materials. Materials enter the rolling cleaning screen from the top, usually by conveying equipment. The screen of the cleaning screen is usually inclined. During the rolling process of the material on the screen surface, larger particles are screened out, while smaller particles or impurities are filtered out by the screen.

[0003] The cleaning screen rotates to make the material roll on the screen surface. The rolling of the material promotes the screening of particles, blocking larger particles on the screen while smaller particles pass through. However, the cleaning screen is prone to encountering large particles or hard objects during operation. These objects can cause a large impact force when the screen rotates, making the screen prone to fatigue damage due to repeated impacts, vibrations, or collisions with large materials. Therefore, we propose a cleaning screen with a pressure dispersion structure. Utility Model Content

[0004] The purpose of this invention is to provide a cleaning screen with a pressure dispersion structure to solve the problem that the cleaning screen mentioned in the background art is prone to encountering large particles or hard objects during operation, which can easily cause a large impact force when the screen rotates, making the screen prone to fatigue damage due to impact.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a cleaning screen with a pressure dispersion structure, comprising a cleaning screen body and a feed inlet.

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-5This utility model provides a technical solution: a cleaning screen with a pressure dispersion structure, including a cleaning screen body 1 and a feed inlet 101. The feed inlet 101 is installed on one side of the cleaning screen body 1, and a screen cylinder 102 is provided on the inner side of the cleaning screen body 1. The two ends of the screen cylinder 102 are respectively fixed to one side of a connecting cover 2, and the other side of the connecting cover 2 is fixed to a connecting plate 201. The connecting plate 201 is movably connected to the cleaning screen body 1 through a bearing, and the outer side of the connecting plate 201 is connected to the inner side of the toothed ring 202. The gear ring 202 is fixed and movably connected to the cleaning screen body 1 via a bearing. The gear ring 202 is opposite to the gear disc 203, and the gear disc 203 is movably connected to the cleaning screen body 1 via a bearing. The gear disc 203 is fixed to the output end of the drive motor 204 via a shaft, and the drive motor 204 is connected to the cleaning screen body 1. The output end of the drive motor 204 is fixed to the small synchronous pulley 205 on the side near the gear disc 203, and the small synchronous pulley 205 is movably connected to the cleaning screen body 1 via a bearing. 05 is connected to one end of the synchronous belt 206, and the other end of the synchronous belt 206 is connected to the large synchronous pulley 207. The large synchronous pulley 207 is movably connected to the cleaning screen body 1 through bearings, and one side of the large synchronous pulley 207 is fixed to the screw rod 208. The screw rod 208 is movably connected to the cleaning screen body 1 through bearings. The inner side of the connecting cover 2 is connected to both ends of the spring 209. The outer side of the screen cylinder 102 is fixed to one end of the bracket 210. The end of the bracket 210 away from the screen cylinder 102 has a passage. The groove 211 has a sliding rod 212 inserted into its inner side. The two ends of the sliding rod 212 are respectively fitted with springs 213, and the springs 213 are respectively connected to the connecting plate 201, the bracket 210 and the sliding rod 212. The connecting cover 2 has a hollow structure and is made of deformable rubber. The toothed ring 202 is meshed with the toothed disc 203. The small synchronous pulley 205 and the large synchronous pulley 207 are meshed with the synchronous belt 206. The inner spacing of the groove 211 is greater than the diameter of the sliding rod 212.

[0023] In specific implementation, according to Figures 1-5When cleaning the screen body 1, the material is fed into the screen cylinder 102 through the feed inlet 101. The drive motor 204 is started, causing the output end of the drive motor 204 to drive the gear disc 203 and the small synchronous pulley 205 to rotate. When the small synchronous pulley 205 rotates, it meshes with the synchronous belt 206 through the small synchronous pulley 205 and the large synchronous pulley 207, so that the small synchronous pulley 205 can drive the large synchronous pulley 207 to rotate through the synchronous belt 206, thereby causing the large synchronous pulley 207 to drive the screw rod. The rotation of screw 208 allows it to assist in the diversion of material, making it easier for the material to be evenly distributed inside the screen cylinder 102. When the toothed disc 203 rotates, the toothed ring 202 meshes with it, allowing it to rotate with the disc. This, in turn, causes the connecting plate 201 to rotate, which in turn, through the connecting cover 2, bracket 210, and slide rod 212, drives the screen cylinder 102 to rotate. The material falls inside the screen cylinder 102, causing it to be impacted. The connecting cover 2, with its hollow structure and deformable rubber material, can deform under pressure. Furthermore, the inner spacing of the through grooves 211 is greater than the diameter of the sliding rod 212, allowing the screen cylinder 102 to shift slightly to cushion the impact. At this time, the spring 209 can be stretched, enhancing the elasticity of the screen cylinder 102 and improving the screening effect. 2. When moving, the through groove 211 of the support 210 slides along the slide rod 212, causing the springs 213 at both ends of the slide rod 212 to extend or contract respectively, further enhancing the vibration effect of the screen cylinder 102. The support 210 and the slide rod 212 slide and connect, which facilitates the connecting plate 201 to drive the screen cylinder 102 to rotate. When the screen cylinder 102 of the cleaning screen is subjected to repeated impacts, it can make a certain displacement to buffer and disperse the pressure, and the screening efficiency of the screen cylinder 102 can also be enhanced.

[0024] In summary, when the drive motor 204 is started and the small synchronous wheel 205 rotates, the screw rod 208 rotates to assist in the diversion of materials, making it easier for the materials to be evenly distributed inside the screen cylinder 102. When the toothed disc 203 rotates, the connecting plate 201 can drive the screen cylinder 102 to rotate through the connecting cover 2, the bracket 210 and the slide rod 212. At this time, the materials fall on the inner side of the screen cylinder 102, and the connecting cover 2 can deform under force, so that the screen cylinder 102 can make a certain displacement to buffer the impact force of the materials. At this time, the spring 209 can enhance the elasticity of the screen cylinder 102, improve the screening effect of the materials, so that when the screen cylinder 102 of the cleaning screen is subjected to repeated impacts, it can make a certain displacement to buffer and disperse the pressure, and the screening efficiency of the screen cylinder 102 can also be enhanced.
