[0022] The inner wall of the filter barrel 117 is provided with a pebble support net 120, pebbles 119 and filter fine sand 118 from bottom to top, wherein the pebble support net 120 is fixed to the inner wall of the filter barrel 117, the pebbles 119 are laid on the pebble support net 120, and the filter fine sand 118 is laid on the pebbles 119, wherein the diameter of the pebbles 119 is larger than the diameter of the through holes of the pebble support net 120, and the pebbles 119 are used to prevent the filter fine sand 118 from passing through the through holes of the pebble support net 120. A cleaning drain pipe 113 is fixedly connected to the side wall of the separation connecting pipe 112, and a cleaning outlet 115 is fixedly connected to the side wall of the cleaning drain pipe 113. The cleaning outlet 115, the cleaning drain pipe 113 and the separation connecting pipe 112 are internally connected, wherein the inner wall of the cleaning drain pipe 113 is slidingly sealed with a switching tube 116, and the switching tube 116 is provided with a switching port 1161 and a switching blocking piece 1162, wherein the switching port 1161 corresponds to the position of the cleaning outlet 115 and is used to cut off or connect the cleaning outlet 115, and the switching blocking piece 1162 corresponds to the position of the separation connecting pipe 112 and is used to cut off or connect the separation connecting pipe 112; a cleaning control electric cylinder 114 is also fixedly installed on the cleaning drain pipe 113, and the cleaning control electric cylinder 114 is used to drive the switching tube 116 to slide on the inner wall of the cleaning drain pipe 113.

[0023] The separation part includes a separation barrel 109, a separation inlet 110 and a separation tube 111, wherein the separation barrel 109 is fixed on the collecting tank 101 through a connecting ring 108, and the separation inlet 110 is provided on the cross-section of the inner wall of the separation barrel 109, the separation tube 111 is coaxially arranged with the separation barrel 109, and the separation tube 111 is connected with the separation connecting tube 112, and the separation tube 111 is located in the inner part of the separation barrel 109 and is also provided with a through hole.

[0024] The waste conveying screw 104 and the collecting screw 103 are driven by a driving motor 107 and a collecting motor 102, respectively, wherein the driving motor 107 is fixed on the frame, and the collecting motor 102 is fixed on the collecting tank 101, wherein the waste collecting tank 106 is coaxially arranged with the waste conveying pipe 105. The cleaning outlet 115 and the separation inlet 110 are connected with a first hose 133 and a second hose 134, respectively.

[0025] One end of the first hose 133 and the second hose 134 is extended into the pool to be filtered. Depending on the substances remaining in the filtered water, one end of the first hose 133 can also be extended into a recovery bucket and can be set separately from the second hose 134.

[0026] When in use, start the water pump 124, the water pump 124 will pump the inside of the filter barrel 117 into a negative pressure, and the inside of the second hose 134 will be pumped into a negative pressure through the separation connecting pipe 112, the separation pipe 111, the separation barrel 109, and the separation inlet 110 (the filter barrel 117, the separation connecting pipe 112, the separation pipe 111, the separation barrel 109, the separation inlet 110 and the second hose 134 are connected), and then the water will enter the second hose 134, and enter the separation barrel 109 through the separation inlet 110 along the tangent direction of the inner wall of the separation barrel 109 (the separation inlet 110 is slightly inclined to the connecting ring 108 by 1-3 degrees), at this time the water will rotate, so that the solid particles with larger mass in the water are separated from the liquid, and then the separated water will enter the separation The solid particles will fall into the separation tube 111 and into the separation barrel 109, and then into the collection tank 101 (the separation barrel 109, the connecting ring 108 and the collection tank 101 are connected). As time goes by, a large amount of solid particles are deposited in the collection tank 101 (initially, there is sludge for plugging in the waste conveying pipe 105, and the solid particles separated later replace the sludge). The collection motor 102 is started, and the solid particles are conveyed to the bottom of the waste conveying pipe 105 by the rotating collection screw 103. Then the drive motor 107 is started, so that the rotating waste conveying screw 104 conveys the solid particles to the top of the waste conveying pipe 105, and then they fall into the waste collection pool 106 for collection. It is necessary to clean the materials inside the waste collection pool 106 regularly.

[0027] The water entering the separation tube 111 will enter the separation connecting tube 112. At this time, the separation connecting tube 112 is not blocked by the switching blocking piece 1162, and the switching port 1161 has blocked the cleaning outlet 115. Therefore, the water will enter the filter barrel 117, and then penetrate to the top of the filter barrel 117 through the pebbles 119 and the filter sand 118. This process requires the selection of the corresponding filter sand 118 according to the nature of the water. In the process of the water passing through the pebbles 119 and the filter sand 118, some small solid particles will remain. These solid particles will be deposited in the gaps of the pebbles 119, and more and more will occur over time. The water enters the top of the filter barrel 117 and enters the water storage tank 129 through the negative pressure drive tube 121. Under the pressure of the water pump 124, the cleaning piston plate 127 moves downward. At this time, the spring 128 is compressed (the inner diameter of the clean water discharge pipe 125 is smaller than the inner diameter of the negative pressure drive tube 121). At the same time, some liquid will flow out through the clean water discharge pipe 125. At this time, the water has been filtered. Because the flow rate of the negative pressure drive tube 121 entering the water storage tank 129 is greater than the clean water discharge pipe 125, the pressure inside the water storage tank 129 will continue to increase until the cleaning piston plate 127 contacts the normally closed button 131. After the normally closed button 131 is pressed by the cleaning piston plate 127, the alarm circuit will be disconnected, and no alarm will occur.

[0028] As time goes by, more and more particles are deposited inside the pebbles 119, and its permeability becomes worse, that is, the flow rate of water through the filtered fine sand 118 is reduced, and the liquid entering the water tank 129 is reduced. At this time, the pressure inside the water tank 129 will be reduced, and the cleaning piston plate 127 will be separated from the normally closed button 131 under the action of the spring 128. At this time, the normally closed button 131 will turn on the alarm circuit and an alarm will be sounded. At the same time, the clean water discharge pipe 125 will be cut off through the second solenoid valve 126, and the water pump 124 will be stopped. Then the first solenoid valve 123 is controlled to open the cleaning return pipe 122. At this time, the liquid inside the water tank 129 will be pushed under the action of the cleaning piston plate 127 and the spring 128, and sent to the top of the filter barrel 117 through the cleaning return pipe 122, and then flow to the pebbles 119 through the filtered fine sand 118, and the particles accumulated in the pebbles 119 will be washed. At the same time, it is necessary to control the cleaning The cleaning control electric cylinder 114 is used to align the switching sealing piece 1162 with the separation connecting pipe 112, and the switching port 1161 with the cleaning outlet 115. At this time, the flushed water will be guided to the cleaning outlet 115 through the switching pipe 116, and then discharged to the designated position through the first hose 133. Since the deposited particles have been deposited for a long time, most of them will stick together to form larger particles, which will cause their mass to increase. Therefore, if the first hose 133 and the second hose 134 are placed together, they can flow back to the separation barrel 109 through the second hose 134. At this time, they can be separated from the water under the action of centrifugal force, and thus collected in the waste collection tank 106. When all the water in the water storage tank 129 is squeezed out by the cleaning piston plate 127, the cleaning control electric cylinder 114 and the water pump 124 are controlled here, and the above steps are repeated to filter the untreated water.
