[0002] Water sample filtration devices are used to remove suspended solids, impurities, or particulate matter from water samples to enable more accurate analysis and detection of water quality. These filtration devices are designed to provide an efficient and precise water sample treatment process for environmental monitoring, ensuring the reliability of experimental results.

[0004] Therefore, a water sample filtration device for environmental monitoring and analysis is proposed. By starting the second motor, the filter barrel is rotated so that the opening faces downward, and under the cleaning of the first cleaning plate, the filter barrel can restore a good filtration effect.

The other end of the second rotating rod 109 is fixedly connected to the outer wall of the filter barrel 101. After a long period of filtration, the filter screen of the filter barrel 101 will become clogged, which will slow down the filtration efficiency. At this time, the second motor 108 is turned on so that the opening of the filter barrel 101 faces downward. Then the first motor 103 is turned on so that the first rotating rod 104 drives the first cleaning plate 105 and the second cleaning plate 107 to clean the filter screen of the filter barrel 101 and wash away the impurities with water flow. This solves the problem that the filter device needs to be disassembled to clean the filter screen, which leads to complicated operation.

[0021] Please see Figure 2In this embodiment, the bristles of the first cleaning plate 105 are in contact with the bottom of the filter tank 101, and the bristles of the second cleaning plate 107 are in contact with the inner wall of the filter tank 101. A third rotating rod 110 is fixedly connected to the left end of the filter tank 101, and the other end of the third rotating rod 110 is rotatably disposed on the inner wall of the filter tank 1. A protective block 111 is fixedly connected to the lower end of the filter tank 101. Multiple heat dissipation holes 112 are opened through the outer wall of the protective block 111. A baffle plate 113 is fixedly connected to the lower end of the protective block 111. By setting the second rotating rod 109 and the third rotating rod 110, the filter tank 101 can be rotated so that impurities can flow out. By setting the baffle plate 113 and the heat dissipation holes 112, the first motor 103 can be prevented from being damaged.

[0022] Please see Figure 3 In this embodiment, the filter assembly includes a fixed ring 201, a sliding plate 202, a first tank 203, a first handle 204, a water collection hopper 205, and a filter plate 206. The filter tank 1 is provided with a fixed ring 201 inside, and a sliding plate 202 is fixedly connected to the outer wall of the fixed ring 201. The filter tank 1 has a first tank 203 at the upper end, and the sliding plate 202 is adapted to the first tank 203. The fixed ring 201 is fixedly connected to the upper end of the fixed ring 201, and a water collection hopper 205 is fixedly connected to the lower end of the fixed ring 201. The water collection hopper 206 is fixedly connected to the lower end of the water collection hopper 205. The liquid will pass through the water collection hopper 205, and under the filtration of the filter plate 206, large impurities will be left inside the water collection hopper 205. After filtration, the water collection hopper 205 can be removed through the first handle 204, and the impurities inside can be cleaned.

[0023] Please see Figure 1 and Figure 4 In this embodiment, the circulation assembly includes a first mounting plate 301, a collection tank 302, a water pump 303, a first outlet pipe 304, a connecting pipe 305, a first solenoid valve 306, and a sampling port 307. The first mounting plate 301 is fixed to the outer wall of the filter tank 1. The collection tank 302 is fixed to the upper end of the first mounting plate 301. The water pump 303 is fixed to the upper end of the collection tank 302. The inlet end of the water pump 303 is located inside the collection tank 302. The outlet end of the water pump 303 is fixed to the first outlet pipe 304. The other end of the first outlet pipe 304 passes through the outer wall of the filter tank 1. The collection tank 302 extends to the top of the filter bucket 101. A connecting pipe 305 is fixed to the left end of the collection tank 302. The other end of the connecting pipe 305 is fixed to the outer wall of the filter tank 1. A first solenoid valve 306 is fixed to the end of the connecting pipe 305 near the filter tank 1. A sampling port 307 is fixed to the front end of the collection tank 302. The liquid will enter the collection tank 302 through the connecting pipe 305. Under the action of the water pump 303, the liquid will enter the filter bucket 101 again through the first water outlet pipe 304, thereby performing circulation filtration, reducing impurities in the liquid and improving the accuracy of water sample analysis.

[0024] Please see Figure 1 In this embodiment, a top cover 2 is threadedly installed on the upper end of the filter tank 1, and multiple support columns 3 are fixedly connected to the lower end of the filter tank 1. A second water outlet pipe 4 is fixedly connected to the filter tank 1, and a second solenoid valve 5 is fixedly connected to the second water outlet pipe 4. By setting the second water outlet pipe 4, sewage can be discharged when cleaning the filter tank 101.

[0025] When using it, first open the top cover 2 and pour the water sample into the filter tank 1. The liquid will pass through the water collection hopper 205 and be filtered by the filter plate 206, leaving large impurities inside the water collection hopper 205. Then the liquid will flow into the filter bucket 101, where it will undergo secondary filtration to further reduce the impurities in the liquid.

[0026] The liquid then enters the collection tank 302 through the connecting pipe 305, and under the action of the water pump 303, the liquid enters the filter bucket 101 again through the first water outlet pipe 304, thereby circulating and filtering, reducing impurities in the liquid and improving the accuracy of water sample analysis.

[0027] After prolonged filtration, the filter screen of the filter canister 101 will become clogged, slowing down the filtration efficiency. At this time, the second motor 108 is turned on so that the opening of the filter canister 101 faces downward. Then the first motor 103 is turned on, causing the first rotating rod 104 to drive the first cleaning plate 105 and the second cleaning plate 107 to clean the filter screen of the filter canister 101. The impurities are washed away by the water flow, which solves the problem of having to disassemble the filter device to clean the filter screen, thus making the operation complicated.

[0028] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
