[0002] Magnetic coagulation water treatment equipment is a new type of complete water treatment process. Its principle is to add special magnetic media during the coagulation process to increase the specific gravity of flocs, which can greatly increase the sedimentation rate of pollutants and effectively reduce the hydraulic retention time, and finally achieve the effect of enhanced flocculation. At the same time, combined with high-efficiency sedimentation and magnetic separation recovery technology, the magnetic medium can be recycled. This technology has the characteristics of fast sedimentation speed, low cost, small footprint, stable and reliable effluent water quality, low energy consumption, high efficiency, etc. It is widely used in black and odorous water bodies, river and lake basin water bodies, municipal sewage and industrial wastewater.

[0003] In the prior art, after the magnetic coagulation water is coagulated, the impurities will gradually sink to the bottom, and recyclable water can be obtained by filtering the upper clear liquid. Since it cannot be guaranteed that the upper clear liquid will not be mixed with impurities and magnetic media, a filter is required to be set for filtering. When the magnetic coagulation water treatment equipment is working for a long time, the filter cannot pass a large amount of water due to the blockage of impurities and magnetic media, and some impurities cannot be removed by cleaning, resulting in a decrease in the water recovery efficiency of the magnetic coagulation water treatment equipment. Since the filter in traditional technology is mostly a fixed structure, it is difficult to replace and clean the filter, which makes it difficult for users to improve the water recovery efficiency of the magnetic coagulation water treatment equipment by replacing the filter.

A magnetic block 47 is fixedly connected to the bottom of the slide rod 44, and a magnetic rotating bar 48 is slidably connected to the outer wall of the magnetic block 47. Before installing the filter screen 42, the sliding bar 5 on the filter pool 3 needs to be removed. When installing the filter screen 42, the fixed frame 41 is inserted into the gap between the filter pool 3. At this time, the sliding bar 5 is pushed into the top of the limit device 4 and the filter pool 3, and the slide rod 44 is pressed down by its own gravity. When the slide rod 44 is pressed down, the positioning ring 46 will be driven to move. At this time, the positioning ring 46 and the fixed mouth 43 will stretch the tension spring 45. At the same time, the magnetic block 47 under the slide rod 44 will push the magnetic rotating bar 48 into the inner wall of the fixed frame 41 due to its arc shape, further restricting the movement of the fixed frame 41, thereby restricting the movement of the filter screen 42.

[0018] The bottom of the filter pool 3 is fixedly connected to the bottom of the servo motor 6, and the output end of the servo motor 6 is fixedly connected with a rotating rod 8, the outer wall of the rotating rod 8 is rotatably connected to the inner wall of the reaction box 1 through a water retaining bearing, and the outer wall of the rotating rod 8 is rotatably connected to the inner wall of the filter pool 3 through a water retaining bearing, the bottom of the sliding bar 5 is slidably connected to the top of the filter pool 3, the top of the tension spring 45 is fixedly connected to the bottom of the fixed nozzle 43, the outer wall of the fixed nozzle 43 is fixedly connected to the top of the inner wall of the filter pool 3, the inner wall of the positioning ring 46 is fixedly connected to the middle part of the outer wall of the sliding rod 44, and the outer wall of the positioning ring 46 is slidably connected to the inner wall of the filter pool 3 through a through hole, and the through hole It is opened in the wall of the filter pool 3, and the bottom of the inner wall of the filter pool 3 is rotatably connected to the outer wall of the magnetic rotating bar 48, and the outer wall of the fixed frame 41 is slidably connected to the outer wall of the filter pool 3.

[0019] Embodiment 2:

[0020] See also Figure 1 - Figure 4The utility model provides a technical solution: on the basis of embodiment 1, the pushing device 7 includes a fixing ring 71, the outer wall of the fixing ring 71 is fixedly connected to the first telescopic rod 72, the outer wall of the first telescopic rod 72 is fixedly connected to the inclined scraper 73, the end of the inclined scraper 73 away from the first telescopic rod 72 is fixedly connected to the second telescopic rod 74, the outer wall of the second telescopic rod 74 is fixedly connected to the sliding ring 75, the inner wall of the sliding ring 75 is rotatably connected to the linkage rod 78, and the outer wall of the linkage rod 78 is provided with a movable rod 77, the outer wall of the movable rod 77 and the outer wall of the linkage rod 78 are both rotatably connected to the connecting frame 76, the outer wall of the connecting frame 76 is fixedly connected to the outer wall of the inclined scraper 73, the end of the movable rod 77 away from the inclined scraper 73 is rotatably connected to the inner wall of the fixing ring 71, and the inner wall of the fixing ring 71 is connected to the rotating rod 8 The outer wall is fixedly connected, and the inner wall of the sliding ring 75 is slidably connected to the outer wall of the rotating rod 8. The servo motor 6 is started to drive the rotating rod 8 to rotate. As the rotating rod 8 rotates, the fixed ring 71 and the sliding ring 75 will be driven to rotate at the same time, so that the pushing device 7 rotates as a whole. Since the inclined scraper 73 has mass, during the rotation of the pushing device 7, the inclined scraper 73 will drive the connecting frame 76 to gradually move away from the axial center of the rotating rod 8. The inclined scraper 73 completes the scraping of impurities accumulated on the filter screen 42 during the rotation of the pushing device 7, so that the filter screen 42 is difficult to be blocked. At the same time, the extended inclined scraper 73 will accelerate the movement of the filtered water on the filter pool 3 through its own inclined surface setting and the rotation of the pushing device 7, and prevent the filtered water from staying in the water flow channel of the filter pool 3 for too long.

[0021] Working principle:

[0022] When in use, the position of the fixing frame 41 and the filter screen 42 is limited by setting the limiting device 4. Before installing the filter screen 42, the sliding bar 5 on the filter pool 3 needs to be removed. When installing the filter screen 42, the fixing frame 41 is inserted into the gap between the filter pool 3. At this time, the sliding bar 5 is pushed into the top of the limiting device 4 and the filter pool 3, and the sliding rod 44 is pressed down by its own gravity. When the sliding rod 44 is pressed down, the positioning ring 46 will be driven to move. At this time, the positioning ring 46 and the fixing nozzle 43 will stretch the tension spring 45. At the same time, the magnetic block 47 under the sliding rod 44 will push the magnetic rotating bar 48 into the inner wall of the fixing frame 41 due to its arc shape, further limiting the The movement of the fixed frame 41 is restricted, thereby limiting the movement of the filter 42. When the filter 42 needs to be replaced and cleaned, the blocking of the sliding bar 5 is removed. At this time, the tension spring 45 will drive the positioning ring 46 to move, so that the positioning ring 46 drives the slide bar 44 to move upward. As the slide bar 44 moves upward, the magnetic block 47 moves upward. Due to the magnetic attraction between the magnetic rotating bar 48 and the magnetic block 47, the upward moving magnetic block 47 sucks the magnetic rotating bar 48 out of the fixed frame 41, so that the fixed frame 41 can be pulled out and then replaced. Due to the separate setting of the fixed frame 41, it is only necessary to replace the blocked filter 42 during replacement, and there is no need to replace all of them at once.

[0023] A pushing device 7 is provided, which is used to scrape and clean the filter screen 42 while pushing the water flow to move. The storage box 2 sends the magnetic medium into the reaction box 1. When the reaction box 1 performs magnetic condensation water treatment, the servo motor 6 is started to drive the rotating rod 8 to rotate. As the rotating rod 8 rotates, the fixed ring 71 and the sliding ring 75 are driven to rotate at the same time, so that the pushing device 7 rotates as a whole. Since the inclined scraper 73 has mass, during the rotation of the pushing device 7, the inclined scraper 73 will drive the connecting frame 76 to gradually move away from the axial center of the rotating rod 8, and drive the first telescopic rod 72 and the second telescopic rod 74 to extend. Since the movable rod 77 and the linkage rod 78 are Each has one end rotatably connected to the connecting frame 76, so during the movement of the connecting frame 76, the movable rod 77 and the linkage rod 78 will be driven to rotate, so that the sliding ring 75 is close to the fixed ring 71. The sliding ring 75 scrapes off the impurities on the rotating rod 8 during the sliding process. At the same time, the inclined scraper 73 is close to the filter screen 42, and completes the scraping of the accumulated impurities on the filter screen 42 during the rotation of the pushing device 7, so that the filter screen 42 is difficult to be blocked. At the same time, the extended inclined scraper 73 will accelerate the movement of the filtered water on the filter tank 3 through its own inclined surface setting and the rotation of the pushing device 7, and prevent the filtered water from staying in the water flow channel of the filter tank 3 for too long.
