DETAILED DESCRIPTION OF THE EMBODIMENTS

[0018] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model. Embodiment

[0019] Please refer to Figures 1-3, the present utility model provides a technical solution: a high-pressure flushing device for filter cloth of a vacuum filter, including a flushing support 3. A filter cloth 1 is arranged on the rear end face of the flushing support 3. A filter cloth winding mechanism is installed on the rear end face of the flushing support 3 for winding the filter cloth 1 after flushing. Flushing roller supports 4 are arranged on both the left and right sides of the flushing support 3, and flushing roller assemblies 5 are installed at the flushing roller supports 4. A flushing pipe assembly 6 is horizontally arranged in the middle of the flushing support 3. A matching flushing cover 7 is covered outside the flushing pipe assembly 6. The flushing cover 7 can prevent the phenomenon of water splashing. A high-pressure water pipe 9 is connected to the left side of the flushing pipe assembly 6. One end of the high-pressure water pipe 9 away from the flushing pipe assembly 6 is provided with a high-pressure pipeline pump 8. One end of the high-pressure pipeline pump 8 away from the high-pressure water pipe 9 is provided with a water tank 10. The high-pressure pipeline pump 8 pumps out the water in the water tank 10 and then transmits it into the high-pressure water pipe 9. The water in the high-pressure water pipe 9 will flow into the flushing pipe assembly 6. The water outlet surface of the flushing pipe assembly 6 faces the filter cloth 1, so as to achieve the effect of high-pressure flushing the filter cloth 1. An adding port 2 is arranged at the top of the water tank 10. A matching driving motor 11 is arranged on the right side of the flushing support 3, and the right side of the flushing pipe assembly 6 is in transmission connection with the driving motor 11. When the driving motor 11 works, it will drive the flushing pipe assembly 6 to swing left and right, so as to achieve the effect of comprehensively flushing the filter cloth 1.

[0020] Among them, preferably, the flushing pipe assembly 6 includes a spray pipe 61. A connector 62 matching with the high-pressure water pipe 9 is arranged on the left side of the spray pipe 61. Water outlet holes 63 and nozzles 64 are arranged in a crossed manner from left to right on the rear end face of the spray pipe 61. The water in the high-pressure water pipe 9 will flow into the spray pipe 61 through the connector 62, and the water in the spray pipe 61 will be sprayed out in two forms from the water outlet holes 63 and the nozzles 64, so as to more comprehensively flush the filter cloth 1.

[0021] Preferably, bolts are arranged between the front, rear, left and right end faces of the flushing cover 7 and the flushing support 3. A fixing ring 71 matching with the spray pipe 61 is arranged on the right side of the inner cavity of the flushing cover 7, and the right side of the fixing ring 71 is connected to the power output end of the driving motor 11. The stability of the connection between the spray pipe 61 and the power output end of the driving motor 11 can be increased by arranging the fixing ring 71.

[0022] Preferably, a motor support plate is installed at the bottom of the driving motor 11. The left side of the motor support plate is fixedly welded to the right side of the flushing support 3. The stability of the connection between the motor support plate and the flushing support 3 can be effectively increased by welding, and the arranged motor support plate can stably install the driving motor 11 on the right side of the flushing support 3. Embodiment

[0023] Refer to Figure 1, what is different from the first embodiment in this embodiment is that: a pump body fixing frame is provided at the bottom of the high-pressure pipeline pump 8, and the high-pressure pipeline pump 8 can be stably installed through the pump body fixing frame. A water pipe is provided between the high-pressure pipeline pump 8 and the water tank 10, and the high-pressure pipeline pump 8 can pump out the water in the water tank 10 through the water pipe; cushion blocks are provided around the bottom of the water tank 10, and the water tank 10 is set as a plastic transparent water tank. The set plastic transparent water tank is light in weight and can more intuitively observe the water consumption and the remaining amount of water in the water tank 10; the length of the spray washing cover 7 from left to right is greater than the length of the spray pipe 61 from left to right. Such a setting can increase the coverage range, reduce the amount of water splashing outside during spraying, and a transparent observation window is provided on the front end face of the spray washing cover 7. The set transparent observation window can facilitate directly observing the process of pipeline water spraying and viewing the flushing process of the filter cloth 1.

[0024] The electrical appliances mentioned in this article are all connected to an external power supply through wires.
