[0026] Reference Figures 1 to 3 The present invention provides a water purification device for a grit chamber, specifically comprising a filter assembly and a drive structure 300 disposed in the grit chamber 100. The drive structure 300 is used to drive the filter assembly to flip into the grit chamber 100 or to flip the filter assembly away from the grit chamber 100. The filter assembly includes a mounting member, and a non-woven fabric 400 laid on the mounting member is locked by a fastening assembly.

[0027] like Figure 1 As shown, the grit chamber 100 of the present application is a rectangular structure, the top surface of the grit chamber 100 is open, the driving structure 300 is fixed to the top of the grit chamber 100, the filter assembly is connected to the driving structure 200, and the two sides of the grit chamber 100 are respectively provided with a water inlet 120 and a water outlet 110.

[0028] Compared with the prior art, the water purification device of the present application can replace the non-woven fabric 400 without draining the water in the grit tank 100. Specifically, when in use, the driving structure 200 drives the mounting part covered with the non-woven fabric 400 to rotate into the grit tank 100 to filter the impurities in the grit tank 100. When it is found that there are more impurities attached to the non-woven fabric 400, the driving structure 200 drives the mounting part to flip to the water surface of the grit tank 100, and then releases the restriction of the fastening component, and then replaces the non-woven fabric 400. The replaced non-woven fabric 400 is then locked by the fastening component, and the replacement is convenient and fast.

[0029] Furthermore, the mounting member includes a first connecting portion 310 and a second connecting portion 320. The first connecting portion 310 is perpendicular to the rotation center of the mounting member. A rotating shaft 331 for placing the non-woven fabric roll 330 is provided at one end of the first connecting portion 310. The second connecting portion 320 is provided at the other end of the first connecting portion 310. The non-woven fabric 400 pulled out of the non-woven fabric roll 330 is locked to the second connecting portion 320 by a fastening component. Figure 2 and Figure 3As shown, the second connecting portion 320 is perpendicular to the first connecting portion 310, and the rotating shaft 331 is also perpendicular to the first connecting portion 310, forming a U-shaped frame to facilitate the fixation of the non-woven fabric 400. When replacing the non-woven fabric 400, the non-woven fabric 400 laid between the rotating shaft 331 and the second connecting portion 320 is cut, and after the restriction of the fastening assembly is released, the cut non-woven fabric 400 is removed. Then, a new non-woven fabric 400 is pulled out from the non-woven fabric roll 330 and laid between the rotating shaft 331 and the second connecting portion 320, and then secured with the fastening assembly. When the non-woven fabric in the entire non-woven fabric roll 330 is used up, the entire non-woven fabric roll 330 is removed and replaced with a new one. The entire replacement process is simple. The U-shaped frame facilitates the fixation and installation of the non-woven fabric 400, and can also prevent the non-woven fabric 400 from being deformed too much. Further, it reduces the impact of flowing water on the non-woven fabric 400, so that the non-woven fabric 400 will not float with the water flow, thereby making the non-woven fabric 400 more effective in settling sand and gravel in the water.

[0030] Further, such as Figure 3 and Figure 4 As shown, the second connecting portion 320 is provided with a slot 321, and the fastening assembly includes a plurality of first locking portions 350. The first locking portions 350, which are spaced apart at the second connecting portion 320, provide pre-pressure to press the non-woven fabric 400 entering the slot 321 against the slot 321. After the non-woven fabric 400 of the non-woven fabric roll 330 is pulled into the slot 321, the first locking portions 350 secure the end of the non-woven fabric 400 in the slot, thereby reducing the impact of flowing water on the non-woven fabric 400 and making replacement of the non-woven fabric 400 more convenient.

[0031] Further, such as Figure 5 As shown, the first locking portion 350 includes a pre-tightening member 352 and a pre-tightening spring 355. The pre-tightening member 352 is inserted into the second connecting portion 320. One end of the pre-tightening member 352 extends through one side wall of the slot 321. Under the action of the pre-tightening spring 355, the pre-tightening member 352 presses the non-woven fabric 400 in the slot 321 against the other side wall of the slot 321. By pulling the pre-tightening member 352, the pressure on the non-woven fabric 400 can be quickly released, making replacement of the non-woven fabric 400 easy.

[0032] Further, such as Figure 5As shown, the first locking portion 350 also includes a sleeve 353 embedded in the second connecting portion 320. The sleeve 353 and the second connecting portion 320 are transitionally matched. Of course, to prevent the sleeve from falling off, bolts can be added for tightening to prevent the sleeve 353 from falling off. One end of the sleeve 353 is fixed and closed, and the other end is detachably closed. The pre-tightening member 352 is inserted into the sleeve 353, that is, the pre-tightening member 352 passes through the sealed ends of the sleeve 353, and the sleeve 353 has a guiding function. The portion of the pre-tightening member 352 located in the sleeve 353 is provided with a limit block 356. One end of the pre-tightening spring 355 provided in the sleeve 353 is fixedly connected to the end of the sleeve 353 facing the slot 321, and the other end of the pre-tightening spring 355 is fixedly connected to the limit block 356. The force of the pre-tightening spring 355 acts on the pre-tightening member 352 through the limit block 356 so that in the absence of external force, the pre-tightening member 352 tends to move toward the wall of the slot 321, thereby pre-tightening and fixing the non-woven fabric 400 in the slot 321.

[0033] In some examples, a pressure plate 354 is provided at one end of the pre-tightening member 352 located in the slot 321, and a pull plate 351 is provided at the other end of the pre-tightening member 352. The pressure plate 354 can better press the non-woven fabric 400, and the setting of the pull plate 351 facilitates the pulling of the pre-tightening member 352, making the operation convenient.

[0034] In a preferred embodiment, the pre-tightening spring 355 is a tension spring, which is sleeved on the pre-tightening member 352 .

[0035] In some other embodiments, the fastening assembly further includes a plurality of second locking portions 340 arranged in an array on the first connecting portion 310. The second locking portions 340 have clamps capable of clamping the non-woven fabric 400. The clamps further pre-tighten the side surfaces of the non-woven fabric 400, thereby reducing the impact of water flow on the non-woven fabric 400.

[0036] In some other embodiments, such as Figure 2 and Figure 3 As shown, the end of the rotating shaft 331 rotatably mounted on the first connecting portion 310 is provided with a handle 332 for rotating the rotating shaft 331, and the other end is provided with a chuck 333 for pre-tightening the non-woven fabric roll 330. The handle 332 allows for rapid rotation of the rotating shaft 331, wherein the rotating shaft 331 is rotatably mounted on the first connecting portion 310 via a bearing, and the chuck 333 is used to secure the non-woven fabric roll 330 to the rotating shaft 331.

[0037] In some other embodiments, the drive structure 300 includes a motor 210 and a drive shaft 220. The drive shaft 220 is rotatably mounted on the top of the grit chamber 100. The motor 210 is rotatably connected to the drive shaft 220 via a coupling, and the mounting member is fixed to the drive shaft 220. Specifically, mounting seats 130 are provided on both sides of the top of the grit chamber 100. Both ends of the drive shaft 220 are rotatably mounted on the mounting seats 130 via bearings. The motor 210 is fixed to the top of the grit chamber 100 and is connected to the drive shaft 220 via a coupling. The end of the first connecting portion 310 of the mounting member is provided with a sleeve end 311 that is conveniently sleeved on the drive shaft 220. The sleeve end 311 is sleeved on the drive shaft 220 and locked with bolts.

[0038] In general, the water purification device of the present application can replace the non-woven fabric 400 without draining the water in the grit chamber 100. Specifically, when in use, the driving structure 200 drives the mounting piece with the non-woven fabric 400 to rotate into the grit chamber 100 to filter the impurities in the grit chamber 100. When more impurities are found on the non-woven fabric 400, the driving structure 200 drives the mounting piece to flip to the water surface of the grit chamber 100 to replace the non-woven fabric 400. When replacing the non-woven fabric 400, cut the non-woven fabric 400 laid between the rotating shaft 331 and the second connecting portion 320. After releasing the restriction of the fastening assembly, remove the cut non-woven fabric 400. Then, pull a new non-woven fabric 400 from the non-woven fabric roll 330 and lay it between the rotating shaft 331 and the second connecting portion 320. Then, secure it with the fastening assembly. When the non-woven fabric in the entire non-woven fabric roll 330 is used up, remove the entire non-woven fabric roll 330 and replace it with a new one. The whole process is simple.

[0039] The embodiments of the present application are described in detail above in conjunction with the accompanying drawings, but the present application is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by ordinary technicians in the technical field without departing from the purpose of the present application.
