It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0020] The utility model provides a coal washing wastewater treatment device, such as Figure 1-4As shown, it includes a treatment tank 1, a water inlet pipe 2, a water outlet pipe 3 and a sewage pipe 4. The water inlet pipe 2 is located on the left side of the treatment tank 1, the water outlet pipe 3 is located at the top of the treatment tank 1, the water outlet pipe 3 is a three-way pipe, the main pipeline of the water outlet pipe 3 is connected to the water storage tank, the secondary pipeline of the water outlet pipe 3 is connected to the driving pump 16, and the output port of the driving pump 16 is communicated with the water storage tank through a connecting pipe, the sewage pipe 4 is located at the bottom of the treatment tank 1, and a filter cartridge 5 is fixedly installed on the top of the inner part of the treatment tank 1. The filter cartridge 5 is located directly below the water outlet pipe 3 and is communicated with it. The filter cartridge 5 The outer rotating sleeve is provided with a collar 6, two collars 6 are provided and are respectively located on the upper and lower sides of the filter cartridge 5, a baffle 7 is fixedly installed on the outside of the collar 6, a scraper 8 is fixedly installed on the inner side of the baffle 7, and the scraper 8 conflicts with the filter screen on the surface of the filter cartridge 5. A limit ring 17 is installed on the lower side of the filter cartridge 5, and a ball 18 is installed on the upper side of the edge of the limit ring 17 in a circumferential array. The limit ring 17 is installed below the filter cartridge 5 through a fixing pin 19. A treatment tank 1 is provided, and sewage enters the treatment tank 1 through the water inlet pipe 2. The filter cartridge 5 in the treatment tank 1 The impurities in the sewage are filtered. This filtering method is an osmotic filtration, which effectively solves the problem that sediments are easily accumulated on the surface of the filtering mechanism. The filtered sewage flows out from the outlet pipe 3 at the top of the treatment tank 1, and the filtered impurities accumulate inside the treatment tank 1. When the sewage enters the treatment tank 1, it will impact the baffle 7 on the outside of the filter cartridge 5. The baffle 7 rotates around the filter cartridge 5 under the impact of the sewage water pressure, so that the scraper 8 on the inside of the baffle 7 scrapes the surface of the filter cartridge 5, and the filter cartridge 5 is continuously cleaned while the sewage is being treated. For cleaning, by arranging left and right driving pumps 16, when it is necessary to clean the inside of the processing tank 1, the driving pump 16 can be started to return the clean water in the water storage tank to the processing tank 1, and the clean water is pressurized by the driving pump 16 to rinse the inside of the processing tank 1, and by arranging a limit ring 17, the limit ring 17 can play a role of limiting the installation of the sleeve ring 6, and the limit ring 17 is installed at the bottom of the filter cartridge 5 through the fixing pin 19. Through this arrangement, the sleeve ring 6 and the scraper 8 can be removed as a whole, thereby facilitating the disassembly and replacement of the filter cartridge 5.

[0021] Five baffles 7 are provided and distributed in a circular array with the filter cartridge 5 as the center. The water outlet of the water inlet pipe 2 is located at the oblique side of the filter cartridge 5 .

[0022] A storage tank 9 is provided on the right side of the treatment tank 1, and a discharge tank 10 is provided at the bottom of the storage tank 9. The flocculant in the storage tank 9 is continuously added with a constant pressure. While the sewage is filtered and discharged, the flocculant in the storage tank 9 falls from the discharge tank 10 into the interior of the treatment tank 1, thereby reacting and purifying harmful substances in the sewage.

[0023] A blocking block 11 is slidably installed inside the feeding chute 10, and a spring 12 is fixedly installed on the inner wall of the feeding chute 10. The other end of the spring 12 is fixedly connected to the blocking block 11, and the end of the blocking block 11 away from the spring 12 is fixedly connected to a connecting rod 13, and the end of the connecting rod 13 away from the blocking block 11 is fixedly connected to a pushing head 14, and the pushing head 14 is in conflict with the baffle 7. By arranging the blocking block 11, the spring 12, the connecting rod 13 and the pushing head 14, the baffle 7 will compress the blocking block 11 inward after contacting the pushing head 14 when it rotates. At this time, the flocculant in the storage trough 9 falls out, and the blocking block 11 is reset under the elastic force of the spring 12 after the baffle 7 is detached. This can be repeated to achieve the purpose of quantitative feeding.

[0024] A water pressure gauge 15 is installed on the left side of the treatment tank 1. The water inlet pipe 2, the water outlet pipe 3 and the sewage pipe 4 are all opened and closed by the electromagnetic valve. The water pressure gauge 15 is electrically connected to the electronic control system and the electromagnetic valve. By setting the water pressure gauge 15, the water pressure in the treatment tank 1 can be detected. When the impurities in the treatment tank 1 accumulate too much, they will adhere to the surface of the filter cartridge 5, and the permeability of the filter cartridge 5 will be reduced. At this time, the water pressure in the treatment tank 1 increases. At this time, the water pressure gauge 15 controls the valves of the water inlet pipe 2 and the water outlet pipe 3 to be closed, and the valve of the sewage pipe 4 to be opened through the electronic control system. At this time, the impurities accumulated in the treatment tank 1 flow out with the sewage in the treatment tank 1. After the sewage is discharged within the set time, the valves of the water inlet pipe 2 and the water outlet pipe 3 are opened, and the valve of the sewage pipe 4 is closed, and the system can work normally.

[0025] The bottom end of the inner wall of the processing tank 1 is set as an arc surface, and the sewage pipe 4 is located at the bottom end of the inner wall of the processing tank 1. The design of the arc surface at the bottom of the processing tank 1 can make it drain more smoothly and avoid impurities remaining inside the processing tank 1.
