Description

Technical Field

[0001] This utility model relates to the field of bar screen cleaning, and more specifically, to a reverse-fishing type bar screen cleaning device. Background Technology

[0002] A bar screen cleaner is a specialized water treatment device that can continuously and automatically intercept and remove debris of various shapes from fluids. It can be widely used in urban sewage treatment, tap water industry, power plant inlets, and can also be used as a pre-screening device in wastewater treatment processes in industries such as textiles, food processing, papermaking, and leather.

[0003] A search revealed that Chinese Patent Publication No. CN220677026U discloses "a reverse-scoop bar screen cleaner. This utility model relates to the field of bar screen cleaning technology. This reverse-scoop bar screen cleaner, by setting up a spray tank, a water storage tank, and nozzles, allows water in the storage tank to flow through an outlet pipe into the spray tank, and then be sprayed out from the spray tank. This allows for backwashing of the conveyor belt's surface and the outer rake plates from the inside, preventing residue on the conveyor belt and rake plates, resulting in better cleaning. By setting up a drive mechanism, rotating rollers, and sponge cleaning strips, the surface of the rake plates can be swept away when the rake plates turn, removing surface dirt. Combined with the spray tank to complete a secondary cleaning, this effectively prevents garbage residue at the bottom of the cleaner, thus avoiding blockage." However, the following defects still exist:

[0004] When cleaning the dirt attached to the surface of the descaling machine, the position of the rotating roller is fixed and the distance between the rotating roller and the surface of the descaling machine cannot be adjusted. If the distance is too close, it may damage the surface of the descaling machine, and some long strips of garbage may get tangled on the rotating roller. If the distance is too far, smaller garbage on the surface of the descaling machine cannot be effectively removed. Therefore, a reverse-scoop type bar screen descaling device is proposed.

[0023] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model.

[0024] Therefore, the following detailed description of the embodiments of this utility model is not intended to limit the scope of the claimed utility model, but merely to illustrate some embodiments of the utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0025] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0026] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0027] like Figure 1-5As shown, this embodiment proposes a reverse-fishing type bar screen cleaning device, including a screen cleaning machine body 1, frame guard plates 2 are provided on both sides of the screen cleaning machine body 1, an adjustment mechanism 3 is provided between the tops of the frame guard plates 2, and a drive assembly 4 is provided on the outer side of the frame guard plates 2.

[0028] like Figure 2 and Figure 3 As shown, the adjustment mechanism 3 includes a cleaning roller 301, an adjustment groove 302, a rotating seat 303, a support seat 304, and an electric pusher cylinder 305. The cleaning roller 301 is disposed between the two side frame guard plates 2. The adjustment groove 302 is opened at the top of the frame guard plate 2, and both ends of the cleaning roller 301 are located in the adjustment groove 302. The rotating seat 303 is rotatably connected to both ends of the cleaning roller 301. The support seat 304 is rotatably connected to the outside of the frame guard plate 2. The bottom of the electric pusher cylinder 305 is fixedly installed on the support seat 304, and the output end of the electric pusher cylinder 305 is fixedly connected to the protruding part on the outside of the rotating seat 303. When in use, the electric push cylinder 305 operates. If it is necessary to move the cleaning roller 301 away from the surface of the decontamination machine body 1, the electric push cylinder 305 extends outward by a certain distance, driving the rotating seat 303 to move. Since the two ends of the cleaning roller 301 are mounted on the rotating seat 303, the cleaning roller 301 can be pushed to move upward by a certain distance in the adjusting groove 302. If it is necessary to move the cleaning roller 301 closer to the surface of the decontamination machine body 1, the electric push cylinder 305 only needs to retract, and the rotating seat 303 will pull the cleaning roller 301 to the bottom. The appropriate method can be selected according to the usage environment and the degree of garbage adhesion.

[0029] like Figure 3 and Figure 4 As shown, the drive assembly 4 includes a drive motor 401, a rotating shaft 402, a first pulley 403, a second pulley 404, and a connecting belt 405. The drive motor 401 is fixedly mounted on the outside of the frame guard plate 2. The rotating shaft 402 is fitted onto the output end of the drive motor 401. The first pulley 403 is fixedly mounted on the rotating shaft 402 via a connecting key. The second pulley 404 is fixedly mounted on the outer end of the cleaning roller 301 via a connecting key. The connecting belt 405 is mounted on the first pulley 403 and the second pulley 404. When the drive motor 401 operates, it drives the first pulley 403 to rotate via the rotating shaft 402, and then drives the second pulley 404 to rotate via the connecting belt 405, thereby driving the cleaning roller 301 to rotate.

[0030] like Figure 1 As shown, a protective box 5 is fixedly installed on the outer side of the frame guard plate 2. The outer side of the protective box 5 can be opened and is made of stainless steel. The protective box 5 protects the transmission mechanism on the outer side of the frame guard plate 2.

[0031] like Figure 2As shown, the path of the adjusting groove 302 is partially arc-shaped, and this partial arc is centered on the axis of the rotating shaft 402. This ensures that the length of the connecting belt 405 does not change during the movement of the cleaning roller 301.

[0032] like Figure 3 As shown, a support plate 6 is fixedly installed between the drive motor 401 and the frame guard plate 2, and a reinforcing plate 7 is fixedly installed between the support plate 6 and the frame guard plate 2. This reinforces the support at the bottom of the drive motor 401 and maintains the stability of the drive motor 401.

[0033] like Figure 4 As shown, the diameter of the first pulley 403 is larger than the diameter of the second pulley 404, and the distance between the first pulley 403 and the second pulley 404 is always constant. This allows the cleaning roller 301 to rotate at a faster speed, resulting in a higher frequency of cleaning the surface of the cleaning machine body 1.

[0034] like Figure 1 As shown, a lighting system 8 is fixedly installed on the inner side of the frame guard plate 2. The lighting system 8 is powered by an external power source. The lighting system 8 uses LED lights to provide brightness for the working environment.

[0035] Specifically, when this reverse-dredging bar screen cleaning equipment is working: the drive motor 401 operates, driving the first pulley 403 to rotate via the rotating shaft 402, and then driving the second pulley 404 to rotate via the connecting belt 405, thereby driving the cleaning roller 301 to rotate and clean the surface of the screen body 1. The position of the cleaning roller 301 is adjusted according to the usage environment and the amount of garbage attached. If it is necessary to move the cleaning roller 301 away from the surface of the screen body 1, the electric push cylinder 305 extends outward by one end, driving the rotating seat 303 to move. Since the two ends of the cleaning roller 301 are mounted on the rotating seat 303, the cleaning roller 301 can be pushed to move upward by one end in the adjusting groove 302. If it is necessary to move the cleaning roller 301 closer to the surface of the screen body 1, the electric push cylinder 305 only needs to retract, and the rotating seat 303 pulls the cleaning roller 301 to the bottom.

[0036] All technical features in this embodiment can be freely combined according to actual needs.

[0037] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
