DETAILED DESCRIPTION

[0032] The technical solutions of the present application will be further described in detail below in combination with specific embodiments.

[0033] The embodiments of the present application are described in detail below, and examples of the embodiments are shown in the drawings, wherein the same or similar reference signs represent the same or similar elements or elements with the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary and are only used to explain the present application, and cannot be understood as a limitation of the present application.

[0034] Please refer to Figure 1 The present embodiment provides a kind of chromone-3-formic acid equipment wastewater treatment device, including box 10, drive assembly 30, cleaning assembly 40, flexible filter layer 50 and winding assembly 60, the water inlet 103 is opened in the top of the box 10, two groups of winding assembly 60 are arranged in the box 10, two groups of winding assembly 60 are symmetrically distributed about the water inlet 103, the flexible filter layer 50 is respectively wound in the outside of two groups of winding assembly 60, for the wastewater that the water inlet 103 enters the inside of the box 10 is filtered, the drive assembly 30 is installed in the inside of the box 10, for driving two groups of winding assembly 60 reciprocating rotation along the same direction, in turn, the flexible filter layer 50 is reciprocally moved, to remove the sundries that remain in the upper portion of the flexible filter layer 50 from below the water inlet 103, the cleaning assembly 40 is arranged in the inside of winding assembly 60, when the sundries in the upper portion of the flexible filter layer 50 are removed from below the water inlet 103, the cleaning assembly 40 is used to clean the sundries.

[0035] When the working wastewater of the chromone-3-carboxylic acid device needs to be filtered, the wastewater can be introduced into the inside of the box 10 from the water inlet 103, and the wastewater can pass through the flexible filter layer 50 after entering the inside of the box 10. The impurities in the wastewater cannot pass through the flexible filter layer 50 due to their large diameter and are thus retained on the upper part of the flexible filter layer 50, achieving filtration treatment of the wastewater. In the above process, the two groups of winding assemblies 60 are driven by the driving assembly 30 to reciprocatingly rotate in the same direction, thereby pulling the flexible filter layer 50 to reciprocatingly move, so as to remove the impurities retained on the upper part of the flexible filter layer 50 from the position below the water inlet 103, thereby preventing the flexible filter layer 50 from being blocked due to too many impurities on the upper part of the flexible filter layer 50, ensuring that the subsequent wastewater can smoothly continue to pass through the flexible filter layer 50, and improving the filtration efficiency of the wastewater. After the impurities on the upper part of the flexible filter layer 50 are removed from the position below the water inlet 103, the cleaning assembly 40 is used to clean the impurities, avoiding the impurities being retained on the upper part of the flexible filter layer 50 all the time, thereby further improving the filtration efficiency of the subsequent wastewater.

[0036] Please refer to Figure 1 、 Figure 2 and Figure 3 In one embodiment, the two groups of winding assemblies 60 are structurally identical and each include a mesh cylinder 603, an end cylinder 605 fixedly arranged at one end of the mesh cylinder 603, and an end plate 601 fixedly arranged at the other end of the mesh cylinder 603. The side of the end plate 601 away from the mesh cylinder 603 is rotatably connected to the inner wall of the box 10 through a rotating shaft 602. The two ends of the flexible filter layer 50 are respectively wound outside the corresponding mesh cylinders 603 of the two groups of winding assemblies 60. The driving assembly 30 includes an elastic rubber strip 301, a transmission gear 302, an incomplete gear 303, and a motor (not shown in the figure). The motor is fixedly installed on the inner wall of the box 10. One side of the incomplete gear 303 is connected to the output end of the motor through a rotating shaft 304. The transmission gear 302 is fixedly arranged outside the rotating shaft 602 and can engage with the incomplete gear 303. One end of the elastic rubber strip 301 is connected to the inner wall of the box 10, and the other end is connected to the end cylinder 605.

[0037] For the convenience of understanding and expression, a group of winding assemblies 60 corresponding net tube 603 is defined as the first net tube, and another group of winding assemblies 60 corresponding net tube 603 is defined as the second net tube. By driving the rotating shaft 304 to rotate, the incomplete gear 303 is driven to rotate. When the incomplete gear 303 is engaged with the transmission gear 302, the corresponding end plate 601 can be driven to rotate by the rotating shaft 602. When the end plate 601 rotates, it can drive the corresponding first net tube and end tube 605 to rotate synchronously. When the first net tube rotates, it can pull one end of the flexible filter layer 50 to move the flexible filter layer 50 in one direction. The second net tube is pulled by the flexible filter layer 50 and rotates in the same direction to unwind the flexible filter layer 50. At the same time, the elastic rubber strip 301 is stretched and wound outside the second net tube 603 when the second net tube rotates. When the incomplete gear 303 is disengaged from the transmission gear 302, the elastic rubber strip 301 pulls the second net tube to rotate in the opposite direction, thereby winding the flexible filter layer 50 to pull the flexible filter assembly 50 to move in the opposite direction. When the incomplete gear 303 is engaged with the transmission gear 302 again, the direction of movement of the flexible filter layer 50 is changed again, realizing the reciprocating movement of the flexible filter layer 50 to remove the impurities on the upper part of the flexible filter layer 50 from below the water inlet 103.

[0038] Please refer to Figure 2 and Figure 3 In one embodiment, the cleaning assembly 40 includes a piston plate 406, a threaded sleeve 404, and a screw rod 405 arranged inside the end tube 605. One end of the screw rod 405 is fixedly connected to the inner wall of the box 10, and the other end extends into the threaded sleeve 404 and is threadedly connected with the threaded sleeve 404. The piston plate 406 is fixedly arranged at the end of the threaded sleeve 404 away from the screw rod 405. The inner wall of the end tube 605 is fixedly provided with a guide strip 604 along the length direction. The side wall of the piston plate 406 is provided with a clamping groove (not shown in the figure) matched with the guide strip 604.

[0039] When the net cylinder 603 drives the end cylinder 605 to rotate in one direction, the piston plate 406 and the threaded sleeve 404 can be driven to rotate synchronously by the cooperation of the guide strip 604 and the piston plate 406, the threaded sleeve 404 can move along the length direction of the screw rod 405 by the cooperation of the threaded sleeve 404 and the screw rod 405, and then the piston plate 406 is driven to move in one direction inside the end cylinder 605. Similarly, when the net cylinder 603 drives the end cylinder 605 to rotate in the other direction, the piston plate 406 and the threaded sleeve 404 can be driven to rotate reversely synchronously by the cooperation of the guide strip 604 and the piston plate 406, the threaded sleeve 404 can move reversely along the length direction of the screw rod 405 by the cooperation of the threaded sleeve 404 and the screw rod 405, and then the piston plate 406 is driven to move in the other direction inside the end cylinder 605. In this way, the reciprocating rotation of the end cylinder 605 can drive the piston plate 406 to move reciprocatingly inside the end cylinder 605, and the piston plate 406 can continuously press and send air into the net cylinder 603 when moving reciprocatingly, and the air is output from the net cylinder 603 and then passes through the flexible filter layer 50 arranged outside the net cylinder 603 to blow away the sundries accumulated on the upper part of the flexible filter layer 50, so as to realize the automatic cleaning of the flexible filter layer 50.

[0040] Please refer to Figure 2 、 Figure 3 and Figure 4 In one embodiment, the cleaning assembly 40 comprises a piston plate 406, a threaded sleeve 404 and a screw rod 405 arranged inside the end cylinder 605. One end of the screw rod 405 is fixedly connected to the inner wall of the box 10, and the other end extends into the threaded sleeve 404 and is threadedly connected with the threaded sleeve 404. The piston plate 406 is fixedly arranged at the end of the threaded sleeve 404 away from the screw rod 405. The inner wall of the end cylinder 605 is fixedly provided with a guide strip 604 along the length direction. The side wall of the piston plate 406 is provided with a clamping groove (not shown in the figure) matched with the guide strip 604. The inner wall of the end cylinder 605 is fixedly provided with a baffle 401. One side of the baffle 401 is provided with a water delivery pipe 402, and the end of the water delivery pipe 402 away from the baffle 401 extends into the net cylinder 603 and is distributed along the axial direction of the net cylinder 603. A plurality of spray holes 403 are formed in the side wall of the water delivery pipe 402 along the length direction. One side of the end cylinder 605 is provided with a water inlet pipe 606, and the end of the water inlet pipe 606 away from the end cylinder 605 is connected with a hose 607. The water inlet pipe 606 and the water delivery pipe 402 are both provided with a one-way valve. The box 20 is provided with two groups of partition plates 20, and a wastewater storage area is formed between the two groups of partition plates 20. The hose 607 extends into the wastewater storage area.

[0041] When the wastewater passes through the flexible filter layer 50, it can fall into the wastewater storage area for temporary storage. When the net cylinder 603 drives the end cylinder 605 to rotate in one direction, the piston plate 406 and the threaded sleeve 404 can be driven to rotate synchronously through the cooperation of the guide strip 604 and the piston plate 406. The threaded sleeve 404 can move along the length direction of the screw rod 405 through the threaded cooperation of the threaded sleeve 404 and the screw rod 405, thereby driving the piston plate 406 to move in one direction inside the end cylinder 605. Similarly, when the net cylinder 603 drives the end cylinder 605 to rotate in the other direction, the piston plate 406 and the threaded sleeve 404 can be driven to rotate reversely synchronously through the cooperation of the guide strip 604 and the piston plate 406. The threaded sleeve 404 can move reversely along the length direction of the screw rod 405 through the threaded cooperation of the threaded sleeve 404 and the screw rod 405, thereby driving the piston plate 406 to move in the other direction inside the end cylinder 605. In this way, the reciprocating rotation of the end cylinder 605 can drive the piston plate 406 to move reciprocatingly in the piston mode inside the end cylinder 605, thereby continuously extracting the filtered wastewater inside the wastewater storage area to the inside of the end cylinder 605 through the hose 607 and the water inlet pipe 606, and then pressurizing the wastewater inside the end cylinder 605 to be sent to the inside of the water conveying pipe 402. When the wastewater enters the inside of the water conveying pipe 402, it can be sprayed out through the plurality of spray holes 403 and then pass out to the outside of the net cylinder 603. In this process, the wastewater passes through the flexible filter layer 50 arranged outside the net cylinder 603 to wash away the debris retained on the upper part of the flexible filter layer 50, thereby realizing the automatic cleaning of the flexible filter layer 50. When the debris is cleaned down from the upper part of the flexible filter layer 50, it can automatically fall to the area outside the two groups of partition plates 20, and the wastewater passing through the flexible filter layer 50 falls to the wastewater temporary storage area between the two groups of partition plates 20, so that the partitioned storage of the debris and the wastewater can be realized.

[0042] In one embodiment, the flexible filter layer 50 can be a steel mesh layer or a nylon mesh layer, which is not limited here.

[0043] Please refer to Figure 1 In one embodiment, the side wall of the box 10 is provided with a cleaning port 101 and a drainage port 102. The cleaning port 101 is communicated with the area outside the two groups of partition plates 20, so as to facilitate the cleaning of the debris falling to the area outside the two groups of partition plates 20. The drainage port 102 is communicated with the wastewater temporary storage area 102, so as to facilitate the drainage of the filtered wastewater from the inside of the box 10.

[0044] When it is necessary to filter the working wastewater of the chromone-3-carboxylic acid device in the embodiment of the present application, the wastewater can be introduced into the inside of the box 10 from the water inlet 103, and the wastewater can pass through the flexible filter layer 50 after entering the inside of the box 10, and the impurities in the wastewater cannot pass through the flexible filter layer 50 due to the large diameter and are retained on the upper part of the flexible filter layer 50, so as to realize the filtration treatment of the wastewater. In the above process, the two groups of winding assemblies 60 are driven to reciprocatingly rotate in the same direction by the driving assembly 30, and then the flexible filter layer 50 is reciprocatingly moved to remove the impurities retained on the upper part of the flexible filter layer 50 from the position below the water inlet 103, so as to prevent the flexible filter layer 50 from being blocked due to too many impurities on the upper part of the flexible filter layer 50, to ensure that the subsequent wastewater can smoothly continue to pass through the flexible filter layer 50, and to improve the filtration efficiency of the wastewater. After the impurities on the upper part of the flexible filter layer 50 are removed from the position below the water inlet 103, the cleaning assembly 40 is used to clean the impurities, so as to avoid the impurities being always retained on the upper part of the flexible filter layer 50, thereby further improving the filtration efficiency of the subsequent wastewater. Compared with the prior art, the chromone-3-carboxylic acid device can realize automatic filtration of the working wastewater, and the filtered impurities can also be automatically cleaned, so as to improve the filtration effect of the wastewater.
