[0018] Example 1

[0019] like Figures 1 to 4 As shown, the present invention proposes a filtration device for the production of spunlace nonwoven fabric, including a filter box 1 and a filtration mechanism; a box cover 101 is detachably installed on the top of the filter box 1 by bolts, and a liquid inlet mechanism is provided on the box cover 101; an annular seat 104 is provided on the inner wall of the filter box 1, and an anti-slip pad is provided on the top of the annular seat 104 to increase the friction between the filter screen 301 and the annular seat 104, and to prevent the filter screen 301 from rotating when the rotating rod 3 rotates; the filtration mechanism is detachably installed inside the filter box 1.

[0020] The filtration mechanism includes a rotating rod 3, a toggle brush 302, and a dispensing pipe 4. A filter screen 301 is rotatably connected to the outer circumference of the rotating rod 3. An anti-slip ring 303 is installed on the outer wall of the filter screen 301. The filter screen 301 abuts against the annular seat 104, and the anti-slip ring 303 abuts against the inner wall of the filter box 1. The toggle brush 302 is installed on the outer circumference of the rotating rod 3. The bristles on the toggle brush 302 are in contact with the filter screen 301. A drain pipe 102 corresponding to the filter screen 301 is installed on the side wall of the filter box 1. An electric valve 103 is provided at the connection between the drain pipe 102 and the filter box 1. The dispensing pipe 4 is installed at the top of the rotating rod 3. Multiple sets of liquid outlets 401 are evenly opened at the bottom of the dispensing pipe 4. The input end of the dispensing pipe 4 is detachably connected to the liquid inlet mechanism, and the dispensing pipe 4 is driven to rotate along the axial direction of the filter box 1 by the liquid inlet mechanism.

[0021] Furthermore, the filter screen 301 on the rotating rod 3 is provided with multiple sets, and the diameter of the filter holes on the multiple sets of filter screens 301 decreases from top to bottom. The annular seat 104 abuts against the lowest set of filter screens 301. The arrangement of multiple sets of filter screens 301 facilitates the step-by-step filtration of sewage and improves the filtration effect. The cross-sectional diameter of the filter screen 301 gradually increases from the top to the bottom, which facilitates the movement of the filtered impurities towards the bottom of the filter screen 301 under the push of the rotating brush 302 and discharge along the sewage pipe 102, reducing the frequency of disassembly and cleaning.

[0022] The liquid inlet mechanism includes a rotating tube 201 and a water inlet tube 204. The rotating tube 201 is driven to rotate and connect to the cover 101 by a driving component 2 installed at the top of the cover 101. The water inlet tube 204 is connected to the cover 101 by a bracket 205. The output end of the water inlet tube 204 is inserted into the rotating tube 201 and the rotating tube 201 is rotatably connected to the water inlet tube 204. The input end of the liquid dispensing tube 4 is detachably connected to the output end of the rotating tube 201.

[0023] In this embodiment, the controller activates the drive unit 2 to drive the rotating tube 201 to rotate at a constant speed. Due to the limiting effect of the bracket 205 on the inlet pipe 204, the rotating tube 201 will not interfere with the inlet pipe 204 when it rotates along the cover 101. Wastewater generated during the production of spunlace fabric is introduced through the inlet pipe 204. The wastewater enters the distribution pipe 4 along the inlet pipe 204 and the rotating tube 201. The rotation of the rotating tube 201 can simultaneously drive the distribution pipe 4 to rotate. The filter screen 301 abuts against the inner wall of the filter box 1 under the action of the anti-slip ring 303. Therefore, when the distribution pipe 4 rotates, it can drive the rotating rod 3 to rotate along multiple sets of filter screens 301. The wastewater falls onto the filter screen 301 along multiple sets of outlets 401 in the distribution pipe 4. With the rotation of the distribution pipe 4, the wastewater can be evenly contacted with the filter screen 301. To improve the utilization rate of filter holes at different positions on filter screen 301, wastewater is filtered step by step through multiple sets of filter screens 301 and falls into the bottom of filter box 1 and is discharged along the drain valve for later use. When the rotating rod 3 rotates along the filter screen 301, it can drive the agitator brush 302 to rotate along the filter screen 301 and push the impurities intercepted on the filter screen 301. Due to the special shape of the filter screen 301, the impurities filtered out on the filter screen 301 move towards the bottom of the filter screen 301 under the push of the agitator brush 302. The agitator brush 302 is designed to prevent the filter holes of the filter screen 301 from clogging and reduce the frequency of disassembly and cleaning of the filter mechanism. After a period of use, the valve port of electric valve 103 can be opened, and the accumulated impurities can be discharged along the drain pipe 102 by the continued rotation of the agitator brush 302, further reducing the frequency of disassembly and cleaning.

[0024] Example 2

[0025] like Figure 4 As shown, the present invention proposes a filtration device for the production of spunlace nonwoven fabric. Compared with Embodiment 1, the bottom end of the rotating tube 201 is connected to a first connecting tube 202, the inner wall of the first connecting tube 202 is provided with a first sealing seat 203, the input end of the liquid distribution tube 4 is connected to a second connecting tube 402, and the outer wall of the second connecting tube 402 is installed with a second sealing seat 403.

[0026] Furthermore, the second connecting pipe 402 is slidably inserted into the inner wall of the first connecting pipe 202 and abuts against the first sealing seat 203. The first connecting pipe 202 abuts against the second sealing seat 403. Both the first sealing seat 203 and the second sealing seat 403 are provided with anti-leakage rings at their abutting ends to improve the sealing performance at the abutting point and prevent leakage.

[0027] Furthermore, both the first connecting pipe 202 and the second connecting pipe 402 are square pipes. When the rotating pipe 201 rotates, the first connecting pipe 202 can drive the second connecting pipe 402 to rotate, thereby driving the separating pipe 4 and the rotating rod 3 to rotate.

[0028] In this embodiment, when the filter mechanism needs to be disassembled and cleaned, the bolts between the cover 101 and the filter box 1 are removed, and the cover 101 is moved upward along the filter box 1 so that the second connecting pipe 402 is no longer connected to the first connecting pipe 202, thus separating the liquid inlet mechanism from the filter mechanism. Then, the liquid separator 4 is held and the filter screen 301 is pulled upward, and the anti-slip ring 303 slides upward along the inner wall of the filter box 1 until it is separated from the filter box 1, thus enabling the filter mechanism to be disassembled, cleaned and maintained regularly.

[0029] 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 thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
