With increasingly stringent environmental regulations, higher demands are being placed on the accuracy and efficiency of water quality testing. Currently, water quality testing often requires pretreatment of water samples to remove large solid particles, preventing these impurities from interfering with test results or damaging testing equipment.

[0003] In existing technologies, water quality testing and filtration techniques mainly include the use of filters or sedimentation. These methods can meet filtration needs to a certain extent, but they suffer from problems such as complex operation, high cost, or low efficiency. When using filters, solid substances are generally filtered by setting up a fixed filter structure in a closed container. However, after long-term use, solid impurities tend to accumulate on the filter, affecting filtration efficiency. Utility Model Content

[0027] like Figure 1-7 As shown, a water quality testing and filtration device includes a housing 1. The housing 1 is provided with an inlet pipe 101 and an outlet pipe 102 that are integrally connected to and distributed vertically thereon. The lower end of the outlet pipe 102 is fixedly connected to a water collection hopper 103 that is connected thereto for collecting filtered water. The device also includes a filtration mechanism 2 and a cleaning mechanism 3 connected to the housing 1. The filtration mechanism 2 is located between the inlet pipe 101 and the outlet pipe 102.

[0028] like Figure 2 , 4 As shown, the filter mechanism 2 includes a mounting frame 201 and a snap-fit ​​assembly 4. Mounting blocks 104 are symmetrically fixed to both sides of the housing 1. Two snap-fit ​​assemblies 4 are symmetrically distributed and connected to the mounting blocks 104. A filter frame 203 is fixed to the lower end of the mounting frame 201. The filter frame 203 is vertically inserted into the housing 1. The snap-fit ​​assembly 4 is used to limit and fix the filter frame 203. A filter screen 204 is provided in the filter frame 203. The filter screen 204 is circular. A rubber sealing strip 205 is fixed to the outside of the filter frame 203. The rubber sealing strip 205 abuts against the inner wall of the housing 1. After the filter frame 203 is inserted into the housing 1, the snap-fit ​​assembly 4 is used to limit and fix the filter frame 203. Then, the filter screen 204 can be used to filter solid impurities in the water.

[0029] like Figure 2 , 3 As shown in Figure 5, the cleaning mechanism 3 includes a motor 301 and a scraper 304. The motor 301 is horizontally fixed to one end of the housing 1. The motor 301 drives the scraper 304 to rotate and cover the circular filter screen 204. A connecting shaft 302 is fixed to the output end of the motor 301. The scraper 304 is vertically fixed to the end of the connecting shaft 302. A limiting disc 303 is fixed to the connecting shaft 302. The limiting disc 303 is rotatably connected to the inner wall of the housing 1, thereby improving the stability of the rotation of the connecting shaft 302. Reinforcing rods 305 are symmetrically fixed to both sides of the connecting shaft 302. The ends of the reinforcing rods 305 are fixed to the scraper 304. The reinforcing rod 305, the connecting shaft 302, and the scraper 304 form a triangular structure, thereby improving the stability of the connection between the scraper 304 and the connecting shaft 302. The lower end of the housing 1 is fixedly connected to a slag discharge shell 105 that communicates with it. The upper opening of the slag discharge shell 105 extends vertically to one side of the filter screen 204. The lower opening of the slag discharge shell 105 is threadedly connected to a sealing cover 106. Solid impurities swept off by the rotating scraper 304 inside the housing 1 are discharged through the slag discharge shell 105. The scraper 304 is driven by the motor 301 to cover the front side of the filter screen 204 and rotate, thereby scraping it and causing the solid impurities to fall into the slag discharge shell 105 and be discharged, thus cleaning the filter screen 204.

[0030] like Figure 4 , 6 As shown in Figure 7, the buckle assembly 4 includes a buckle block 401 and a slide rod 403. The mounting block 104 has a sliding groove 107 extending through its outer side. The mounting bracket 201 has through holes 202 on both sides. The buckle block 401 is inserted into the through holes 202. The buckle block 401 has a triangular cross-section. The buckle block 401 is horizontally slidable within the sliding groove 107 and extends horizontally outward from the mounting block 104. The sliding groove 107 has limiting grooves 108 on its upper and lower sides. The buckle block 401... A limiting plate 402 is fixedly connected to both ends of the limiting plate 402, which is horizontally slidably fitted in the limiting groove 108. The sliding rod 403 is horizontally fixedly connected in the limiting groove 108. The limiting plate 402 is slidably connected to the sliding rod 403. A spring 404 is sleeved on the sliding rod 403. The two ends of the spring 404 are fixedly connected to the rear end of the limiting plate 402 and the inner wall of the limiting groove 108. By pressing the locking block 401 into the through hole 202 to retract it into the sliding groove 107, the filter frame 203 can be removed and disassembled from the box 1.

[0031] In use, the filter frame 203 is vertically inserted into the housing 1. The two ends of the mounting bracket 201 are pressed downwards against the inclined surfaces of the locking blocks 401 extending from the outside of the mounting block 104, causing the locking blocks 401 to retract into the sliding groove 107 and compress the spring 404. After the filter frame 203 is fully inserted into the housing 1, the locking blocks 401 extend outwards from the outside of the mounting block 104 under the action of the spring 404 and into the through hole 202, thus limiting and fixing the mounting bracket 201, thereby completing the installation of the filter screen 204. The inlet pipe 101 and the outlet... The valve on the water pipe 102 opens both, and the water to be tested is introduced through the inlet pipe 101. After the solid impurities are filtered out by the filter screen 204, the water is collected by the water collection hopper 103 through the outlet pipe 102. When the solid impurities are filtered by the filter screen 204, the output end of the motor 301 drives the connecting shaft 302 to rotate, which in turn drives the scraper 304 to cover and scrape the front side of the filter screen 204, so that the solid impurities fall into the slag discharge shell 105. The solid impurities can be discharged from the box 1 by opening the lower end of the slag discharge shell 105 through the sealing cover 106.

[0032] When the filter screen 204 needs to be disassembled for cleaning after long-term use, press the locking block 401 into the through hole 202, so that the locking block 401 retracts into the slide groove 107, and then the mounting bracket 201 can be pulled upwards away from the box 1, and then the filter frame 203 can be pulled out of the box 1 to clean the filter screen 204.

[0033] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
