The water purification circulation filter can greatly improve the sewage filtration and purification effect through layer-by-layer filtration by setting the filter box, the slide groove, the slider, the fine sand box, the acrylic cotton layer, the activated carbon layer, the PE filter core layer and the placement box, and pulling the pull block can make the fine sand box and the placement box slide in the slide groove and be pulled out of the filter box, so that it is more convenient to replace the filter material and clean up impurities.

A support plate 203 is fixed to the inner peripheral wall of the filter frame 202, and a coarse filter screen 204 is placed on the upper surface of the support plate 203. When the sewage is introduced into the body 1 through the water supply pipe for circulation purification, the sewage is first filtered through the coarse filter screen 204 to intercept and filter the major impurities in the sewage. Two slide rails 205 are fixed between the inner walls on the left and right sides of the body 1.

The upper surface of the flushing pipe 210 is connected to no less than two nozzles 211.

[0024] In this embodiment, a closed door is hinged on the front of the body 1 through a hinged frame, and a controller is fixed on the front of the closed door. The length and width of the filter frame 202 are respectively equal to the length and width of the upper surface of the body 1. A deflector is fixed on the upper surface of the filter frame 202, and the upper surface of the deflector is connected to a water supply pipe.

[0025] See also Figure 3 In order to improve the water purification effect of the filter, the purification mechanism 3 in this embodiment includes a sedimentation tank 301 fixed on the inner bottom wall of the body 1. The filtered sewage is introduced into the sedimentation tank 301 through a drainage cover 302, so that the solid particles are settled to the bottom through the sedimentation tank 301, thereby reducing the suspended matter in the water. The drainage cover 302 is fixed on the upper surface of the sedimentation tank 301, and the right inner wall of the sedimentation tank 301 is connected with a dosing pipe 303. According to the pH value, chemical substances such as flocculants, deodorants or regulators are added to the sedimentation tank 301 through the dosing pipe 303 to improve the quality and taste of water.

[0027] The working principle of the above embodiment is:

[0028] (1) When the filter is used to improve the filtering efficiency, when the sewage is introduced into the body 1 through the water supply pipe for circulation purification, the sewage is first filtered through the coarse filter 204 to intercept and filter the major impurities in the sewage. When cleaning, it is only necessary to disassemble the filter frame 202 for cleaning. At the same time, the sewage after coarse filtration passes through the first filter 207 and the second filter 208 in turn. When the sewage passes through these media, particulate matter, microorganisms and organic matter will be captured or adsorbed to improve the efficiency of removing pollutants and microorganisms. The installation frame 206 can be pulled and moved along the slide rail 205 for disassembly and maintenance. After filtering for a period of time, the right end of the diverter pipe 209 can be connected to the external pump body, and then the water flow is pumped along the diverter pipe 209 to multiple flushing pipes 210, and further sprayed from the multiple nozzles 211 onto the filter screen to use pressure or water flow to reversely flush the filter medium, flush out the trapped pollutants to achieve backwashing, so as to maintain the filtering effect of the filter screen and improve the filtering efficiency.

[0029] (2) When the filter is used to improve the water purification effect, the filtered sewage is introduced into the sedimentation tank 301 through the drainage cover 302, and is allowed to stand in the sedimentation tank 301 so that the solid particles are settled to the bottom, thereby reducing the suspended matter in the water. At the same time, the pH meter 307 can be used to detect the pH of the water in the sedimentation tank 301. According to the pH, chemical substances such as flocculants, deodorants or regulators are added to the sedimentation tank 301 through the dosing pipe 303 to improve the quality and taste of the water. After the water reaches the use standard, the water pump 304 can be started to extract the filtered water through the pumping pipe 305 in conjunction with the filter cotton and discharge it to the outside, so as to improve the purification and circulation filtering effect of the water.
