Description

Technical Field

[0001] This utility model relates to the technical field of bar screen cleaning machines, specifically a bar screen cleaning machine with adjustable width. Background Technology

[0002] Bar screens are advanced water treatment equipment whose main functions are as follows: 1. Intercepting solid debris: Bar screens effectively intercept solid debris in wastewater, such as branches, leaves, and plastic bags, preventing them from entering subsequent treatment stages and avoiding blockages and damage to pipes, pumps, valves, and other equipment; 2. Protecting downstream equipment: By intercepting solid debris, bar screens protect the normal operation of downstream treatment equipment, such as pumps, valves, and pipes, extending their service life; 3. Improving treatment efficiency: After removing solid debris from wastewater, bar screens reduce the load on subsequent treatment processes, improving wastewater treatment efficiency and creating favorable conditions for biological treatment and advanced treatment. Their applications are wide-ranging, including urban wastewater treatment, the water supply industry, power plant inlets, and wastewater treatment processes in industries such as textiles, food processing, papermaking, and leather.

[0003] As disclosed in patent announcement number CN218573007U, a bar screen with adjustable width is included. The bar screen includes a body with bar screens inside. Bar screens are fixedly installed on both sides of the bar screen. A chain assembly is also installed inside the body, and drive wheels are rotatably installed on both sides of the body. This patent states that by installing the bar screen between the chains on both sides, the drive wheels can cause the bar screen to rotate cyclically inside the body. The bar screens, which discharge material through intersections, treat impurities in the wastewater. The distance between two adjacent bar screens can be adjusted by moving the bar screen via a mounting shaft. After the pin is released, the tension spring loses its tension and resets, and the bar screen is positioned by the tension spring support. This allows for easy adjustment of the bar screen distance to meet the needs of different fields, making the bar screen more versatile and eliminating the need for rework when changing applications.

[0004] However, the bar screen mentioned in the patent has a structure for catching floating debris that is inconvenient to disassemble and assemble. When it is damaged, it needs to be returned to the factory for repair. Moreover, after long-term operation, a large amount of floating debris will remain on the structure for catching floating debris, causing the floating debris to fall back to the water surface.

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 1-4 As shown, this utility model provides a technical solution:

[0023] An adjustable-width bar screen cleaning machine includes a drive motor 101. A fixing plate 102 is fixedly installed at the front end of the drive motor 101. Fixing screws 103 are fixedly installed on the fixing plate 102. A cleaning mechanism 104 is provided at the front end of the fixing plate 102. The cleaning mechanism 104 includes a transmission box 105. The drive motor 101 is fixedly installed at the right end of the transmission box 105. A sliding groove 201 is opened inside the transmission box 105. A support plate 202 is fixedly installed between the transmission boxes 105. A slot 203 is opened on the lower side of the support plate 202. A guide sprocket 204 is movably installed at the corner inside the transmission box 105.

[0024] The above solution allows the drive motor to be fixed by screws through the fixing plate, which in turn provides power for the cleaning process. The transmission box allows the transmission components to be installed, the sliding groove allows the sliding rod to pass through and move, the support plate can support the caught floating objects, and the trough opening allows water to flow and blocks floating objects.

[0025] In this embodiment, preferably, the decontamination mechanism 104 further includes a drive chain 205, which is movably installed inside the transmission box 105, and a guide sprocket 204 is movably installed on the outside of the drive chain 205.

[0026] The above scheme allows the rotation direction of the drive chain to be changed by the guide sprocket, and the reciprocating rotation of the drive chain can move the cleaning rod.

[0027] In this embodiment, preferably, a drive sprocket 206 is movably installed on the inner side of the drive chain 205, and a drive shaft 301 is fixedly installed between the drive sprockets 206. The drive shaft 301 passes through the transmission box 105 and is fixedly installed on the drive end of the drive motor 101.

[0028] The above scheme allows the drive motor to rotate the drive shaft, which in turn causes the drive sprocket to rotate the drive chain.

[0029] In this embodiment, preferably, a transmission chain 302 is movably mounted on the outer side of the drive sprocket 206, a transmission sprocket 303 is movably mounted on one end of the inner side of the transmission chain 302, a transmission shaft 304 is fixedly mounted between the transmission sprockets 303, and a brush 305 is fixedly mounted on the outer side of the transmission shaft 304.

[0030] The above solution involves driving the sprocket to rotate, which in turn drives the transmission chain to rotate. This rotation of the sprocket, in turn, drives the transmission shaft to rotate. When the transmission shaft rotates, the brush rotates and interacts with the cleaning rod, which can clean the residual floating matter on the cleaning rod.

[0031] In this embodiment, preferably, a sliding rod 306 is fixedly installed on the inner side of the drive chain 205, and a connecting rod 401 is fixedly installed between the sliding rods 306. A sliding groove 402 is opened on the front side of the connecting rod 401, and a sliding block 403 is fixedly installed in the sliding groove 201.

[0032] With the above scheme, the sliding rod can pass through the sliding groove and connect to the drive chain, the connecting rod can support the cleaning rod, and the sliding groove can allow the sliding block to be slidably installed and adjusted.

[0033] In this embodiment, preferably, the sliding block 403 has a connecting screw groove 404 at its front end, a connecting screw 405 is fixedly installed in the connecting screw groove 404, and a cleaning rod 406 is fixedly installed at the front end of the connecting screw 405.

[0034] The above solution involves installing the cleaning rod by connecting the screw and the connecting screw groove, which allows the cleaning rod to be fixed and locked. Furthermore, the sliding block can be controlled to slide by turning the connecting screw.

[0035] In this embodiment, an adjustable-width bar screen cleaner operates by using a drive motor 101 to rotate a drive shaft 301, which in turn causes a drive sprocket 206 to rotate a drive chain 205. As the drive chain 205 rotates, it is guided by the drive sprocket 206 and guide sprocket 204 within the transmission box 105, resulting in reciprocating rotation and a change in its rotation direction. This causes the sliding rod 306 to slide within the sliding groove 201, which in turn causes the connecting rod 401 to reciprocate between the transmission boxes 105. When the connecting rod 401 moves, its front end, the cleaning rod 406, rises from the bottom of the water to collect pollutants floating on the surface. Further displacement causes the floating debris to be moved by the cleaning rod 406 onto the tray 202, resulting in its discharge. Simultaneously, as the drive motor 101 rotates, the transmission... The chain 302 is driven to rotate, causing the transmission sprocket 303 to drive the transmission shaft 304 to rotate, which in turn causes the brush 305 to start rotating. The brush 305 is located below the drive shaft 301, so the rotation direction of the brush 305 is opposite to the movement direction of the cleaning rod 406. This allows the brush 305 to clean the residual floating objects on the cleaning rod 406 by rotating when it engages with the cleaning rod 406, preventing the floating objects from falling back onto the water surface. When the spacing of the cleaning rod 406 needs to be adjusted, the user can loosen the cleaning rod 406 by turning it through the connecting screw 405 in the connecting screw groove 404. This allows the sliding block 403 to slide in the sliding groove 402 to adjust the spacing. The connection between the connecting screw 405 and the connecting screw groove 404 makes it easier to replace the cleaning rod 406.
