[0027] It is understandable that, referring to Figures 1 to 4 The membrane residue filtering device of the present invention includes a frame 100, a first filtering mechanism 200 and a second filtering mechanism 300. The first filtering mechanism 200 includes a connecting cylinder 210, a rotating cylinder 220 and a driving member 230. The connecting cylinder 210 is rotatably connected to the frame 100. The bottom end of the connecting cylinder 210 is provided with a first through hole 211. The rotating cylinder 220 is rotatably connected to the connecting cylinder 210. The driving member 230 is used to drive the rotating cylinder 220 to rotate. The side wall of the rotating cylinder 220 is provided with a plurality of second through holes 221. The rotating cylinder 220 is provided with a plurality of second through holes 221. There is a first filter screen 222, which abuts against the second through hole 221, and is used to filter waste liquid; the second filtering mechanism 300 includes a liquid storage tank 310 and a second filter screen 320, the liquid storage tank 310 is fixedly connected to the frame 100 and is located below the connecting tube 210, the upper end of the liquid storage tank 310 is set as an opening 311, the second filter screen 320 is detachably connected to the opening 311, the second filter screen 320 can be docked with the first through hole 211, and the second filter screen 320 is used to receive and filter waste liquid.

[0028] The connecting cylinder 210 is rotatably connected to the frame 100, and the rotating cylinder 220 is arranged in the connecting cylinder 210, and the rotating cylinder 220 is rotatably connected to the connecting cylinder 210. The first filter screen 222 is set in the rotating cylinder 220, and the waste liquid is passed into the rotating cylinder 220. The rotating cylinder 220 is driven to rotate by the driving member 230 so that the waste liquid can be dispersed onto the first filter screen 222. The waste liquid can be filtered for the first time through the first filter screen 222, so that the filtered waste liquid can enter the connecting cylinder 210 through the second through hole 221 and flow out from the first through hole 211. The liquid storage tank 310 is fixedly connected to the frame 100 and is located below the connecting cylinder 210. The second filter screen 320 is detachably connected to the opening 311, so that the waste liquid flowing out of the second through hole 221 can pass through the second filter screen 320 to filter the waste liquid for the second time and store it in the liquid storage tank 310, thereby improving the filtering effect of the waste liquid and reducing the mixing of membrane residue in the waste liquid. The driving member 230 can drive the rotating drum 220 to rotate, so that the waste liquid can be evenly distributed on the first filter screen 222, promoting the flow of the waste liquid, reducing the long-term use of a single filter surface, reducing the risk of blockage, and improving the filtration efficiency of the waste liquid.

[0029] In addition, the connecting tube 210 is rotatably connected to the frame 100. By rotating the connecting tube 210, the position of the connecting tube 210 can be easily adjusted, so that the first filter 222 can be easily maintained without the need for workers to climb to a high place, which facilitates the cleaning or replacement of the first filter 222 and improves the convenience of maintenance.

[0030] The driving member 230 may be an electric motor, a pneumatic motor, a hydraulic motor, etc., which is not limited here.

[0031] It should be noted that the upper end of the connecting cylinder 210 is connected to an end cap, which is provided with a liquid inlet. The liquid inlet is located below the rotating cylinder 220, allowing waste liquid to fall into the rotating cylinder 220 when input through the liquid inlet, thereby facilitating filtration of the waste liquid and improving filtration efficiency. The output shaft of the driving member 230 passes through the end cap, and the output shaft of the driving member 230 and the rotating cylinder 220 can be connected by a spline, which facilitates separation of the end cap from the connecting cylinder 210 and improves maintenance convenience.

[0032] It is understandable that, referring to Figure 2The rotating cylinder 220 is provided with a first cylinder wall 223 and a second cylinder wall 224. The first cylinder wall 223 and the second cylinder wall 224 are arranged radially. The second through hole 221 is arranged on the first cylinder wall 223. A gap 225 is provided between the first cylinder wall 223 and the second cylinder wall 224. The first filter screen 222 is arranged in the gap 225. The first cylinder wall 223 and the second cylinder wall 224 are arranged radially. The second cylinder wall 224 is located inside the first cylinder wall 223. A gap 225 is provided between the first cylinder wall 223 and the second cylinder wall 224. By arranging the first filter screen 222 in the gap 225, the first filter screen 222 can be stabilized between the first cylinder wall 223 and the second cylinder wall 224, thereby preventing the first filter screen 222 from shaking and preventing waste liquid from bypassing the first filter screen 222 and being output from the second through hole 221, thereby improving the filtering effect of the waste liquid.

[0033] It should be noted that the second cylinder wall 224 can have multiple water holes so that waste liquid can pass through the first filter screen 222. In addition, the first filter screen 222 is annular in shape, so that the first filter screen 222 can fit the first cylinder wall 223 and the second cylinder wall 224, thereby improving the filtering effect.

[0034] Specifically, refer to Figure 2 A plurality of support plates 226 are provided at the upper end of the second cylinder wall 224. The plurality of support plates 226 are arranged at intervals along the circumference of the second cylinder wall 224, and the first filter screen 222 can abut against the support plates 226. The support plates 226 are fixedly connected to the upper end of the second cylinder wall 224, and the plurality of support plates 226 are arranged at intervals along the circumference of the second cylinder wall 224. The plurality of support plates 226 abut against the first filter screen 222. The plurality of support plates 226 can support the first filter screen 222, thereby preventing the first filter screen 222 from deforming and colliding with the first cylinder wall 223, thereby extending the service life of the first filter screen 222 and improving the reliability of the first filter mechanism 200.

[0035] In addition, the plurality of support plates 226 are arranged at intervals so that waste liquid can pass through the gap 225 between two adjacent support plates 226 , thereby facilitating the waste liquid to pass through the first filter screen 222 .

[0036] Specifically, refer to Figure 2The inner wall of the second cylinder wall 224 is connected to a slag retaining ring 227, which is arranged obliquely toward the bottom wall of the second cylinder wall 224. The slag retaining ring 227 is connected to the inner wall of the second cylinder wall 224 and is arranged obliquely toward the bottom wall of the second cylinder wall 224. This allows waste liquid to flow into the rotating cylinder 220, allowing film residue in the waste liquid to settle at the bottom of the rotating cylinder 220. The film residue can slide along the oblique direction of the slag retaining ring 227, thereby guiding the film residue to accumulate at the bottom of the rotating cylinder 220. When the driving member 230 drives the rotating cylinder 220 to rotate, the film residue at the bottom can be blocked by the slag retaining ring 227 from axial movement along the second cylinder wall 224, thereby reducing the amount of film residue remaining on the first filter screen 222, reducing the possibility of clogging the first filter screen 222, and improving reliability.

[0037] It is understandable that, referring to Figure 1 and Figure 2 The connecting tube 210 is fixedly connected to an adjustment plate 212. The adjustment plate 212 is provided with a plurality of adjustment holes 213 at intervals along the circumference. The frame 100 is threadedly connected to a bolt 110, and the bolt 110 is passed through the adjustment hole 213. The adjustment plate 212 is fixedly connected to the connecting tube 210. The plurality of adjustment holes 213 are arranged at intervals along the circumference of the adjustment plate 212. The bolt 110 is threadedly connected to the frame 100 and passed through the adjustment hole 213. By screwing the bolt 110 in or out of the adjustment hole 213, the position of the connecting tube 210 can be locked or unlocked, making it easier for workers to maintain the first filter 222. In addition, the plurality of adjustment holes 213 are arranged at intervals along the circumference of the adjustment plate 212. By setting the bolt 110 to pass through different adjustment holes 213, the inclination angle of the connecting tube 210 can be adjusted, thereby improving the convenience of maintenance.

[0038] It is understandable that, referring to Figure 3 and Figure 4 Guide bars 312 are connected to both sides of the opening 311, and guide grooves 321 are connected to the second filter 320. The guide bars 312 can be slidably connected to the guide grooves 321. The two guide bars 312 are arranged on both sides of the opening 311, and the guide grooves 321 are connected to both sides of the second filter 320. By arranging the guide bars 312 in the guide grooves 321, the second filter 320 can be easily arranged in the opening 311, improving the maintenance convenience of the second filter 320.

[0039] It should be noted that, by aligning the guide bar 312 with the guide groove 321 and then pushing the guide groove 321 into the guide bar 312 , the second filter screen 320 can be easily installed in the liquid storage tank 310 .

[0040] Specifically, refer to Figure 3 and Figure 4A baffle 313 is rotatably connected to one side of the opening 311, and the baffle 313 is snap-fitted to the liquid storage tank 310, so that the second filter 320 can abut against the baffle 313. One end of the baffle 313 is rotatably connected to one side of the opening 311, and the other end of the baffle 313 is snap-fitted to the liquid storage tank 310. By providing the second filter 320 with abutment against the baffle 313, the baffle 313 can define the position of the second filter 320, thereby stabilizing the position of the second filter 320 and preventing waste liquid from passing through the gap 225 between the second filter 320 and the liquid storage tank 310, thereby improving the filtering effect.

[0041] It should be noted that the baffle 313 is flipped open from the liquid storage tank 310 so that the second filter 320 can be loaded or removed from the guide bar 312, and then the baffle 313 is snapped onto the liquid storage tank 310. The second filter 320 can be cleaned or replaced without additional tools, thereby improving the convenience of maintenance.

[0042] It is understandable that, referring to Figure 1 and Figure 4 The liquid storage tank 310 is provided with a liquid outlet 314, and the liquid outlet 314 is detachably connected to a cover 315, which can block the liquid outlet 314. The liquid storage tank 310 is provided with a liquid outlet 314, and the cover 315 is detachably connected to the liquid outlet 314. By providing the cover 315, the liquid outlet 314 can be easily opened or closed, and the waste liquid in the liquid storage tank 310 can be easily discharged, thereby improving the convenience of use of the membrane residue filtration device.
