A scraper 106 is slidably connected to the top of the filter plate 104, and specifically, the scraper and the filter plate are kept relatively movable and not relatively rotatable through a keyway structure. In the preferred structure, a slider can be set on the scraper, a slide groove is opened on the filter plate, and the slider is matched with the slide groove. The slider can adopt a T-shaped structure, so that a good connection between the scraper and the filter plate can be achieved, and the cleaning and output effect of impurities can be enhanced.

The stirring motor 231 is fixedly installed on the upper ring plate 211 through a bracket, and the central shaft 232 is vertically distributed between the upper ring plate 211 and the lower ring plate 212, and is adapted to be installed at the mounting hole 215, and is connected to the stirring motor, and the stirring motor drives the central shaft to rotate synchronously. The central shaft 232 is connected to the mounting hole 215 through a bearing; the first stirring rod 233 is a T-shaped structure, and one end is fixedly installed on the central shaft 232; the cleaning sponge 234 is fixedly installed on the first stirring rod 233. In a preferred embodiment, the cleaning sponge can also be replaced by a cleaning brush.

Then, under the condition of differential rotation, the cleaning brush will strengthen the 360-degree cleaning of the rubber ball, thereby completely separating the impurities and providing favorable conditions for the subsequent centralized collection and cleaning of impurities.

[0034] The working principle of the present invention is as follows: water flow and rubber balls enter the joint pipe 401 through the external return pipe. At this time, the electromagnetic switch valve at the bottom of the joint pipe is closed, and the joint pipe forms a temporary, sealed pretreatment space. Turn on the stirring motor, and the stirring motor will synchronously drive the central axis to rotate clockwise at a synchronous high speed. At this time, the multiple stirring rods and cleaning brushes distributed on the central axis will rotate and stir the mixed flow of rubber balls in the pretreatment space. At the same time, since the central axis and the driving wheel are an integrated structure, the driving wheel will drive the meshing driven wheel to rotate, thereby forming a sun-planet structure, and then drive multiple stirring shafts to start rotating at a counterclockwise speed. Since the diameter of the driven wheel is smaller than the diameter of the driving wheel, the meshing transmission of the two forms a reduction transmission, and the stirring shaft will rotate at a low speed. At this time, the cleaning brush on the central axis rotates clockwise at a high speed, and the cleaning brush on the stirring shaft rotates counterclockwise at a low speed, which will perform a full-range, no-dead-angle cleaning operation on the rubber balls in the pretreatment space.

[0035] Then, after a preset period of rotation and cleaning, the electromagnetic switch valve is opened, and the cleaned rubber balls and water flow enter the filter tube 101 through the connection between the No. 3 flange 402 and the No. 2 flange 103. Through the transparent observation window 110, the operator can observe the filtering process in real time to ensure the filtering effect. The No. 1 electric push rod 105 controls the rotation of the filter plate 104 through telescopic action, and regularly shakes off the impurities on the filter plate 104. The No. 2 electric push rod 107 controls the sliding of the scraper 106 through telescopic action, scrapes off the impurities on the filter plate 104 and pushes them to the right side of the filter plate 104. The impurities are discharged through the waste pipe 108 and finally fall into the waste collection box 109. The clean water flow and rubber balls enter the ball collecting frame 1 and are further filtered and separated through the inclined grid plate 2. The inclination angle of the grid plate 2 is conducive to the separation of the rubber balls and the water flow. The rubber balls are intercepted on the grid plate 2, and the water flow continues to flow out. The recovered rubber balls and the water flow are transported to the rubber ball pump 8 through the inclined lead-out pipe 7. The rubber ball pump 8 transports the rubber balls and the water flow back to the ball loading room to prepare for the next cleaning cycle. The water pump 116 draws water from the waste collecting box 109 and returns the water to the filter tube 101 through the water supply pipe 117, forming a closed-loop water circulation system to reduce the waste of water resources.

[0036] The device forms a closed-loop water circulation system by adding a filter element 100. The intelligent condenser cleaning device can not only filter impurities in the reflux liquid more effectively and prevent impurities from re-entering the cleaning device, but also improve the automation level and resource utilization rate of the system. These improvement measures not only extend the service life of the equipment, but also improve the cleaning effect, ensure the heat exchange efficiency of the condenser, and reduce the waste of water resources, thereby improving the environmental protection and economy of the system.

[0037] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
