A filter assembly 110 is relatively arranged in the filter chamber 101, and the filter assembly 110 includes a first filter plate 300 and a second filter plate 320 arranged relatively, and a plurality of filter plates 300 and 320 are evenly arranged on the first filter plate 300. The first filter hole 301 is provided with a second filter hole 321 on the second filter plate 320 corresponding to the first filter hole 301, a dredging cavity 314 is provided between the first filter plate 300 and the second filter plate 320, a dredging component is provided in the dredging cavity 314, the dredging component includes a dredging rod 311 which can be located and moved in the dredging cavity 314, the dredging rod 311 can be extended into the corresponding first filter hole 301 and the second filter hole 321, and a scraping component is provided on the plate surface of the first filter plate 300 and the second filter plate 320 which are far away from each other.

[0030] In this embodiment, sewage enters the filter chamber 101 through the water inlet pipe 102, and flows out through the first filter hole 301 and the second filter hole 321. Impurities in the sewage are intercepted by the first filter plate 300 and the second filter plate 320. The filtered sewage is discharged from the outlet pipe 103 and enters the next process for further purification.

[0031] Among them, through the setting of the dredging component, when the filtering effect of the filter component 110 becomes poor, the filter component 110 can be taken out of the filter chamber 101, and the dredging rod 311 is reciprocated in the dredging chamber 314, so that the dredging rod 311 reciprocates into the corresponding first filter hole 301 and the second filter hole 321 to dredge the first filter hole 301 and the second filter hole 321 to prevent impurities from clogging the first filter hole 301 and the second filter hole 321, thereby affecting the filtering effect; in actual use, in order to improve the dredging effect, the filter component 110 can be flushed while the dredging component is working, thereby improving the dredging effect of the dredging component;

[0032] The scraping assembly is provided so that the plate surfaces of the first filter plate 300 and the second filter plate 320 can be scraped and swept to separate impurities gathered on the plate surfaces, thereby improving the filtering effect of the filter assembly 110 .

[0033] like Figure 3As shown, in this embodiment, the dredging component also includes a dredging plate 310 arranged in the dredging chamber 314, both ends of the dredging rod 311 extend through the dredging plate 310, a connecting block 313 is provided at the top of the dredging plate 310, a connecting hole 402 is provided in the connecting block 313, a motor 340 is provided at the top of the first filter plate 300, the output shaft of the motor 340 is threaded through the connecting hole 402, a bearing seat 322 is provided at the top of the second filter plate 320, the corresponding end of the output shaft of the motor 340 is installed on the bearing seat 322, and the motor 340 rotates to drive the dredging plate 310 to move in the dredging chamber 314.

[0034] In this embodiment, the connecting block 313 is threadedly connected to the output shaft of the motor 340, and the two side surfaces of the dredging plate 310 are limited and fixed by the side walls of the dredging chamber 314. When the motor 340 is started, the output shaft of the motor 340 rotates to drive the connecting block 313 to move along it, thereby driving the dredging plate 310 to reciprocate in the dredging chamber 314. When the dredging plate 310 is close to the first filter plate 300, the dredging rod 311 extends into the first filter hole 301 to separate the impurities gathered in the first filter hole 301. When the dredging plate 310 is close to the second filter plate 320, the dredging rod 311 extends into the second filter hole 321 to separate the impurities gathered in the second filter hole 321.

[0035] Among them, through the setting of the bearing seat 322, one end of the output shaft of the motor 340 is fixed so that it will not be skewed when rotating, which will affect its normal use;

[0036] A mounting bracket for fixing the motor 340 is also provided at the top of the first filter plate 300 . By providing the mounting bracket, the motor 340 can be better installed and fixed on the first filter plate 300 .

[0037] like Figure 3 and Figure 4 As shown, in this embodiment, a plurality of guide rods 401 are provided between the first filter plate 300 and the second filter plate 320 , and the guide rods 401 are provided through corresponding dredging plates 310 .

[0038] In this embodiment, by setting the guide rod 401, when the dredging plate 310 moves, since the guide rod 401 passes through the corresponding dredging plate 310, the dredging plate 310 can only move along the guide rod 401, which can play a guiding role, thereby better facilitating the dredging rod 311 to extend into the corresponding first filter hole 301 and the second filter hole 321.

[0039] like Figure 3 As shown, in this embodiment, a plurality of flow grooves 312 are evenly arranged on the dredging plate 310 .

[0040] In this embodiment, the sewage entering the dredging cavity 314 through the first filter hole 301 can flow through the flow groove 312, and will not cause the sewage to be unable to flow in the dredging cavity 314, thereby affecting the purification of the sewage.

[0041] like Figure 3 As shown, in this embodiment, the scraping assembly includes a bracket 302 disposed at a plate surface of the first filter plate 300 , a movable groove 303 is disposed between the bracket 302 and the first filter plate 300 , and a movable scraper 304 is disposed in the movable groove 303 .

[0042] In this embodiment, the scraper 304 moves in the moving groove 303 , so that the impurities gathered on a surface of the first filter plate 300 can be cleaned by the scraper 304 and then separated from the first filter plate 300 .

[0043] like Figure 3 As shown, in this embodiment, a fixing rod 305 is provided on one side of the bracket 302 away from the first filter plate 300, and a side wall of the fixing rod 305 is slidably abutted against an outer side wall of the bracket 302, and a side wall of the fixing rod 305 is fixedly connected to the two ends of the scraper 304 at both ends.

[0044] In this embodiment, one side wall of the fixing rod 305 is slidably pressed against the outer side wall of the bracket 302, and both ends of the fixing rod 305 are connected to the two ends of the scraper 304. Through this structure, the scraper 304 is limited by the fixing rod 305 when moving and will not be skewed. That is, in actual use, the scraper 304 can be driven to move by moving the fixing rod 305, which is simple and convenient to operate.

[0045] like Figure 1 and Figure 2 As shown, in this embodiment, a plurality of snap-in grooves 200 are provided on the side wall of the filter cavity 101 along its height direction.

[0046] In this embodiment, the first filter plate 300 and the second filter plate 320 are respectively inserted into the corresponding snap-in grooves 200. This structure facilitates the installation of the first filter plate 300 and the second filter plate 320 in the filter chamber 101. After the first filter plate 300 and the second filter plate 320 are inserted into the corresponding snap-in grooves 200, screws can be used to perform secondary reinforcement on the first filter plate 300 and the second filter plate 320 to prevent them from being moved by the flowing sewage during use, causing displacement, resulting in a gap between the first filter plate 300 and the second filter plate 320 and the filter chamber 101, thereby affecting the filtering effect.

[0047] When it is actually used, a sealing gasket is provided in the snap-in groove 200. Through this structure, the first filter plate 300 and the second filter plate 320 can be sealed when snapped into the snap-in groove 200, thereby ensuring the filtering effect.

[0048] like Figure 3 As shown, in this embodiment, a plurality of handles 323 are provided between the corresponding first filter plates 300 and the second filter plates 320 .

[0049] In this embodiment, the first filter plate 300 and the second filter plate 320 are connected by the provision of the handle 323. When the filter assembly 110 needs to be taken out, the first filter plate 300, the second filter plate 320 and the dredging plate 310 can be driven to move synchronously by holding the handle 323. At the same time, there are multiple handles 323. When taking out and placing the filter assembly 110, it can be taken out from any side of the filter box 100, which is more convenient to use.

[0050] In actual use, two filter assemblies 110 are provided. When one of the filter assemblies 110 needs to be cleaned, the other filter assembly 110 can be used normally without stopping and will not affect its normal filtering.

[0051] Working principle: When sewage needs to be purified, the sewage is discharged into the filter chamber 101 through the water inlet pipe 102, and the sewage enters the dredging chamber 314 through the first filter hole 301 and is discharged through the second filter hole 321. Impurities in the sewage are intercepted by the first filter hole 301 and the second filter hole 321, and are gathered on the first filter plate 300 and the second filter plate 320. The filtered sewage is discharged from the water outlet pipe 103 and enters the next process for further purification. When it is necessary to clean the first filter plate 300 and the second filter plate 320, the sewage can be cleaned by holding the handle 323. The first filter plate 300, the second filter plate 320 and the clearing plate 310 are taken out of the filter chamber 101, and the motor 340 is started to move the clearing rod 311 to clear the impurities in the first filter hole 301 and the second filter hole 321, and the bracket 302 is manually moved to drive the scraper 304 to move, so that the plate surfaces of the first filter plate 300 and the second filter plate 320 that are far away from each other are scraped to separate the impurities gathered on the outer plate surface, and the plate surfaces of the first filter plate 300 and the second filter plate 320 that are close to each other are rinsed with an external water pipe to separate the impurities on the inner plate surface.
