Detailed Implementation

[0031] To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.

[0032] like Figures 1 to 8 As shown, a groundwater treatment filtration device in one embodiment of the present invention includes: a filter box 1 and a filter plate device 2.

[0033] like Figures 1 to 4 As shown, an inlet 101 is fixed on the filter box 1, and a secondary filter box 102 is provided on one side of the filter box 1. The inlet 101 is used for sewage to enter the device, and the secondary filter box 102 is used for secondary filtration of the sewage. An outlet 103 is fixed on the secondary filter box 102, through which the filtered sewage in the secondary filter box 102 is discharged and enters the next treatment process. A partition 104 is fixed inside the filter box 1, which is used to divide the internal space of the filter box 1. A cavity 112 is provided on the side of the partition 104 near the secondary filter box 102. A sedimentation tank 105 is fixed at the bottom of the cavity 112. The sewage flowing into the filter box 1 falls into the cavity 112 after preliminary filtration by the main filter plate 203, and then flows into the secondary filter box 102 through the transmission pipe 113. The sedimentation tank 105 is used to settle heavier particles.

[0034] like Figures 1 to 4 As shown, a garbage box 111 is installed on the other side of the partition 104, and a top cover 108 is installed on the filter box 1. The garbage box 111 is used to store garbage. During later maintenance, the top cover 108 is opened to inspect the inner wall of the filter box 1. The secondary filter box 102 is equipped with multiple filter media 110, which perform multiple stages of filtration on the sewage, such as coarse filtration, fine filtration, and deep filtration. A transmission pipe 113 connects the filter box 1 and the secondary filter box 102. The sewage that has been filtered in the filter box 1 flows into the secondary filter box 102 through the transmission pipe 113.

[0035] like Figures 1 to 4 As shown, a pair of guide plates 109 are fixed at the upper and lower ends of the inlet of the transmission pipe 113 inside the cavity 112. The pair of guide plates 109 guide the sewage that has been initially filtered on the main filter plate 203, causing the heavier particles in the sewage to fall into the sedimentation tank 105, thereby filtering out the heavier particles in the sewage. A retaining rail 106 is fixed at the bottom of the sedimentation tank 105, and a baffle 107 is slidably installed inside the retaining rail 106. Pulling the baffle 107 out of the retaining rail 106 allows the particles deposited in the sedimentation tank 105 to be discharged.

[0036] like Figures 5 to 8 As shown, the filter plate device 2 is installed inside the filter box 1. The filter plate device 2 includes a first bushing 201, which is fixed to the top of the partition 104. A first rotating shaft 202 is rotatably arranged inside the first bushing 201, which drives the second cross arm 207 to rotate. Multiple second cross arms 207 are fixed on the first rotating shaft 202. A main filter plate 203 is fixed at the upper end of the cavity 112 inside the filter box 1. Multiple first cross arms 204 are fixed on the main filter plate 203. The first cross arms 204 and the second cross arms 207 are staggered to form a filter screen, which performs preliminary filtration of sewage. At the same time, when the first rotating shaft 202 is rotated to drive the second cross arms 207, the second cross arms 207 rotate the filtered and deposited garbage into the garbage box 111.

[0037] like Figures 5 to 8 As shown, a second bushing 210 is fixed on the side wall of the filter box 1 near the garbage box 111. A second rotating shaft 211 is rotatably arranged inside the second bushing 210. Multiple cleaning rods 212 are fixed on the second rotating shaft 211. The cleaning rods 212 and the second cross arm 207 are arranged alternately. The second cross arm 207 rotates to one side of the garbage box 111. After the garbage is put into the garbage box 111, the second rotating shaft 211 is rotated. The second rotating shaft 211 drives the cleaning rods 212 to rotate. The cleaning rods 212 remove the debris adhering to the second cross arm 207.

[0038] like Figures 5 to 8As shown, the main filter plate 203 has the same number of first support grooves 206 as the second cross arms 207. One end of the second cross arm 207 away from the first rotating shaft 202 is located within the first support groove 206. This arrangement allows the main filter plate 203 to support the second cross arms 207, enabling the second cross arms 207 and the first cross arms 204 to filter impurities in the wastewater together. Multiple first partitions 205 are fixed to the first cross arm 204, and multiple second partitions 208 are fixed to the second cross arm 207. Each pair of adjacent first partitions 205 and second partitions 208 are staggered, allowing them to work in conjunction with the first cross arms 204 and 207 for filtration.

[0039] like Figures 5 to 8 As shown, the second bushing 210 has a number of second support grooves 213, the same as the number of second cross arms 207. One end of the second cross arm 207 away from the first rotating shaft 202 is located within the second support groove 213. Because the second end of the second cross arm 207 away from the first rotating shaft 202 is located within the second support groove 213, the second bushing 210 supports the second cross arm 207. A first rotating handle 209 is installed at the end of the first rotating shaft 202 located outside the filter box 1. The first rotating handle 209 is used to drive the first rotating shaft 202 to rotate. A second rotating handle 214 is installed at the end of the second rotating shaft 211 located outside the filter box 1. The second rotating handle 214 is used to drive the second rotating shaft 211 to rotate.

[0040] Working principle: When this device is in use, sewage flows into the filter box 1 from the inlet 101. After the sewage is initially filtered by the filter screen composed of the second horizontal arm 207 and the first horizontal arm 204, it flows into the cavity 112. Then, through the guidance of a pair of guide plates 109, the heavier particles in the sewage are deposited into the sedimentation tank 105. Then, it flows into the secondary filter box 102 through the transmission pipe 113 for multiple stages such as coarse filtration, fine filtration and deep filtration. Finally, it flows out through the outlet 103 to enter the next treatment process.

[0041] When there is a large amount of debris deposited on the second horizontal arm 207 and the first horizontal arm 204, it can be handled by means of... Figure 5 As shown, rotating the first rotary handle 209 counterclockwise causes the first rotary shaft 202 to rotate, which in turn causes the second horizontal arm 207 to rotate. The second horizontal arm 207 then rotates the deposited garbage around the first rotary shaft 202 to one side of the garbage container 111, thus disposing of the garbage into the container. After rotating 180 times, the state of the second horizontal arm 207 changes from as shown... Figure 5 The conversion shown is as follows Figure 7In the state shown, the second rotating handle 214 is then rotated, which drives the second rotating shaft 211 to move as shown. Figure 5 As shown, rotating clockwise, the second shaft 211 drives the cleaning rod 212 to rotate, so that the cleaning rod 212 scrapes off the garbage adhering to the second cross arm 207. Then, the cleaning rod 212 rotates back, and at the same time, the second cross arm 207 rotates back, so that the second cross arm 207 and the first cross arm 204 form a filter screen again.

[0042] When removing particulate matter deposited in sedimentation tank 105, baffle 107 can be pulled out from rail 106, and then the particulate matter deposited in sedimentation tank 105 can be discharged.
