A full cotton spunlace nonwoven fabric wastewater treatment device and method

Abstract

This invention discloses a wastewater treatment device and method for all-cotton spunlace nonwoven fabric, relating to the field of wastewater treatment technology. The device includes a wastewater treatment tank, a collection tank, a drive structure, two sets of trajectory running structures, and a pusher block. This invention utilizes the coordinated action of the pulling and restraining units in the trajectory running structure to move the pusher block along a rectangular closed trajectory of backward, downward, forward, and upward movement, sequentially completing the functions of drainage, scraping and conveying impurities, and resetting after impurity removal. When the pusher block moves forward, it contacts the opening and closing structure, automatically opening the sealing door through the mechanical linkage of the contact plate, slide rod, connecting plate, guide plate, and connecting rod, and closing it as the pusher block resets. This eliminates the need for a separate power source or sensor for the sealing door, simplifying the device structure and reducing manufacturing costs and control complexity.

Description

Technical Field

[0001] This invention relates to the field of wastewater treatment technology, specifically to a wastewater treatment device and method for all-cotton spunlace nonwoven fabric. Background Technology

[0002] The production process of all-cotton spunlace nonwoven fabric generates a large amount of wastewater containing short fibers, flocs and suspended solids, which is usually treated by flocculation combined with filtration.

[0003] Existing wastewater treatment equipment is generally equipped with fixed filter plates. After the wastewater undergoes flocculation reaction above the filter plates, the treated water is discharged through the filter holes. The intercepted impurities need to be cleaned regularly.

[0004] However, existing equipment relies heavily on manual labor or additional independent power mechanisms (such as cylinders or electric push rods) to control the opening and closing of the waste discharge gate in the impurity cleaning and waste discharge operations, resulting in complex equipment structure, high manufacturing costs, and cumbersome control logic. Secondly, during the flocculation reaction stage, the filter pores are usually in a normally open state, which can easily cause leakage of water samples that have not been fully reacted. During the drainage stage, the filter pores may become clogged, resulting in poor drainage. There is a lack of an automatic switching mechanism for the open and closed states of the filter pores.

[0005] Based on this, we now provide a wastewater treatment device and method for all-cotton spunlace nonwoven fabrics, which can eliminate the drawbacks of existing equipment. Summary of the Invention

[0006] The purpose of this invention is to provide a wastewater treatment device and method for all-cotton spunlace nonwoven fabrics to solve the problems in the background art.

A fixing plate is fixed inside the wastewater treatment tank. A discharge port is opened through the connection between the side wall of the wastewater treatment tank and one side of the fixing plate. The lowest end of the discharge port is flush with the upper end of the fixing plate. A sealing door is slidably installed inside the discharge port. Several filter holes are opened through the fixing plate. The pusher block is installed inside the wastewater treatment tank and is located at the upper end of the fixed plate; The collection box is fixed to the front end of the wastewater treatment tank. A collection tray is slidably installed inside the collection box. A guide opening is provided at the upper end of the collection box. An opening and closing structure for controlling the opening and closing of the sealing door is installed at the guide opening. The drive structure is installed on the outer wall of the wastewater treatment tank. The drive structure is connected to the trajectory running structure and is used to drive the trajectory running structure to move the push block. Two sets of trajectory running structures are symmetrically installed on the two inner side walls of the wastewater treatment tank. Each trajectory running structure includes a pulling unit and a constraint unit, both of which are connected to a push block. The pulling unit is connected to a drive structure. The pulling unit is located inside the wastewater treatment tank and is used to pull the push block to move. The constraint unit is located at the top of the wastewater treatment tank and is used to constrain the movement trajectory of the push block. When the pusher moves to the discharge port, the pusher drives the opening and closing structure to open the sealing door at the discharge port, so as to discharge impurities into the collection drawer inside the collection box.

[0008] Preferably, the pulling unit includes a rotating block, a sliding tube, a limiting block, a limiting ring, a return spring, a pull rod, and a rotating ring; The rotating block is rotatably installed on the inner side wall of the wastewater treatment tank and is connected to the drive structure.

[0009] Preferably, the constraint unit includes two fixing blocks, a constraint plate, a sleeve frame, and a constraint rod; Two fixing blocks are symmetrically fixed on both sides of the upper end of the wastewater treatment tank. A constraint plate is fixed between the two fixing blocks. A frame is slidably fitted on the constraint plate. A constraint rod is fixed at the lower end of the frame. The outer wall of the constraint rod is slidably connected to the inner wall of the constraint opening. The constraint opening is opened through the upper end of the push block.

[0010] Preferably, the drive structure includes a motor, two sets of transmission units and a rotating rod. The two sets of transmission units are symmetrically installed on the outer walls at both ends of the wastewater treatment tank, and the two sets of transmission units are connected by the rotating rod. The transmission unit includes a first transmission wheel, a transmission belt, and a second transmission wheel. The first transmission wheel is rotatably mounted on the outer side wall of one end of the wastewater treatment tank, and the first transmission wheel is fixedly connected to a rotating block on the inner side wall of the same end of the wastewater treatment tank. Two fixing ears are symmetrically fixed on both sides of the rear end of the wastewater treatment tank, and the second transmission wheel is rotatably mounted on the fixing ears. The first transmission wheel and the second transmission wheel are connected by a transmission belt. The second transmission wheel of this group of transmission units is fixedly connected to the second transmission wheel of another group of transmission units through a rotating rod. The motor is installed on the outer wall of the wastewater treatment tank, and the output end of the motor is fixedly connected to a transmission wheel located on the outer wall of the same wastewater treatment tank.

[0011] Preferably, a slot is provided at the corner of the side end and the lower end of the push block, and a scraper is provided inside the slot. The corner of the slot and the side end of the push block is rotatably connected to the corner of the scraper, and a stop block is fixed at the corner inside the slot.

[0012] Preferably, the opening and closing structure includes a contact plate, a slide rod, a return spring, a connecting plate, a guide plate, and a connecting rod; The contact plate is installed inside the wastewater treatment tank and is located above the fixed plate. The rear side wall of the wastewater treatment tank has several sliding openings, and a sliding rod slides in each opening. One end of the sliding rod extends into the wastewater treatment tank and is fixedly connected to the contact plate. The other end of the sliding rod extends into the outside of the wastewater treatment tank and is fixedly connected to the connecting plate. A second return spring is fixed between the connecting plate and the outer wall of the wastewater treatment tank. The second return spring is sleeved on the outer wall of the sliding rod. Several guide plates are fixed at the lower end of the connecting plate. Each guide plate slides with a guide opening. The lower end of the guide plate extends through the guide opening into the collection box. The guide plate is fixedly connected to the sealing door inside the collection box by a connecting rod.

[0013] Preferably, a fixing frame is fixed to the inner wall of the wastewater treatment tank. The fixing frame is located directly below the fixing plate. A baffle plate is provided between the fixing frame and the fixing plate. The outer wall of the baffle plate is slidably connected to the inner wall of the wastewater treatment tank. Several baffle blocks are fixed to the upper end of the baffle plate. Each baffle block is slidably fitted with a filter hole on the fixing plate. Several water outlet holes are opened through the baffle plate.

[0014] Preferably, the upper end of the fixed frame is fixedly connected to the lower end of the shielding plate by a number of reset springs. Two vertical plates are symmetrically fixed on both sides of the upper end of the shielding plate, and two vertical openings are symmetrically opened through both sides of the upper end of the vertical plates. Each vertical plate slides into one vertical opening.

[0015] A method for treating wastewater from spunlace nonwoven fabric manufacturing includes the following steps: Step 1: Flocculation reaction. Wastewater enters the wastewater treatment tank through the inlet pipe. At this time, the filter holes are blocked by the baffle block, and the wastewater stays above the fixed plate. Flocculant is added to react and generate flocs. Step 2: Drainage is opened. The drive structure drives the push block to move horizontally backward and then vertically downward through the trajectory running structure. The downward push block pushes the vertical plate to make the baffle plate move downward. The baffle block disengages from the filter hole, and the treated water is discharged from the outlet pipe through the filter hole and the outlet hole. Step 3: Impurity pushing. After the pusher moves down to contact the fixed plate, it changes to moving forward horizontally, pushing the flocculated material trapped on the fixed plate toward the impurity discharge port. Step 4: Impurity discharge. As the pusher moves forward, it touches and drives the opening and closing structure, opening the sealing door and pushing the flocs through the impurity discharge port into the impurity collection tray of the collection box. Step 5: Reset. Driven by the track running structure, the push block first moves vertically upward and then horizontally backward, returning to its initial position. At the same time, the baffle and sealing door automatically reset.

[0016] A manufacturing process for a wastewater treatment device for all-cotton spunlace nonwoven fabric includes the following steps: Step 1: Process the wastewater treatment tank, fix the inlet pipe to the top of one side of the wastewater treatment tank, fix the outlet pipe to the bottom of one side of the wastewater treatment tank, fix the fixing plate inside the wastewater treatment tank, open several filter holes on the fixing plate, open the discharge port on the side wall of the wastewater treatment tank, and slide and install the sealing door inside the discharge port. Step 2: Assemble the baffle assembly. Make several water outlet holes through the baffle. Fix the baffle block to the upper part of the baffle. Fix the vertical plate to both sides of the upper part of the baffle. Fix one end of the reset spring to the lower end of the baffle and the other end to the upper end of the fixing frame. Fix the fixing frame to the inner wall of the wastewater treatment tank and to the bottom of the fixing plate. Make the baffle block slide and fit with the filter holes. Make the vertical plate pass through the vertical opening on the fixing plate. Step 3: Install the opening and closing structure. Fix the contact plate to one end of the slide rod. Slide the slide rod into the sliding opening on the side wall of the wastewater treatment tank. Set the two return springs on the outside of the slide rod and abut against the connecting plate and the outer wall of the wastewater treatment tank. Fix the connecting plate to the other end of the slide rod. Fix the upper end of the guide plate to the lower end of the connecting plate. Fix the lower end of the guide plate to the sealing door through the connecting rod. Step 4: Install the trajectory running structure. Symmetrically rotate and install the rotating blocks of the two sets of pulling units on the two inner side walls of the wastewater treatment tank. Create side sliding openings through the rotating blocks. Slide the sliding tube inside the side sliding openings. Fix a limiting block at one end of the sliding tube and a limiting ring at the other end. Place three return springs on the outside of the sliding tube, abutting against the rotating block and the limiting ring. Fix a slider at one end of the pull rod and slide the slider inside the sliding tube, allowing the pull rod to pass through the hole in the limiting ring. Fix the rotating ring at the other end of the pull rod. Symmetrically fix the fixing blocks of the two sets of constraint units on both sides of the upper end of the wastewater treatment tank. Fix the constraint plate between the two fixing blocks. Slide the frame onto the constraint plate. Fix the upper end of the constraint rod to the lower end of the frame. Step 5: Install the push block. Make a slot at the corner of the side and bottom of the push block. Fix the abutment block at the corner inside the slot. Rotate and install the scraper block inside the slot so that one corner of the scraper block is rotatably connected to the corner of the slot. Fix the rotating shaft to the side wall of the push block. Set the push block on the upper part of the fixed plate. Rotate the rotating ring and fit it on the outer side wall of the rotating shaft. Slide the lower end of the constraint rod into the constraint opening at the upper end of the push block. Step Six: Install the drive structure, fix the motor to the outer wall of the wastewater treatment tank, rotate and install the first transmission wheel on the outer wall of the wastewater treatment tank and fix it to the rotating block, fix the fixing ears symmetrically on both sides of the rear end of the wastewater treatment tank, rotate and install the second transmission wheel on the fixing ears, put the transmission belt on the first and second transmission wheels, fix both ends of the rotating rod to the second transmission wheels of the two sets of transmission units respectively, and fix the motor output end to the first transmission wheel of one of the sets of transmission units. Step 7: Install the waste collection box. Fix the waste collection box to the front end of the wastewater treatment tank. Make a guide opening at the top of the waste collection box so that the guide plate passes through the guide opening and the waste collection tray is slidably installed inside the waste collection box.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. This invention utilizes the coordinated action of the pulling and constraint units in the trajectory running structure to enable the push block to move along a rectangular closed trajectory of backward, downward, forward, and upward movement, sequentially completing the functions of drainage, scraping and conveying impurities, and resetting after impurity removal. When the push block moves forward, it touches the opening and closing structure, and through the mechanical linkage of the contact plate, slide rod, connecting plate, guide plate, and connecting rod, the sealing door automatically opens and closes as the push block resets. This eliminates the need for a separate power source or sensor for the sealing door, simplifying the equipment structure and reducing manufacturing costs and control complexity.

[0018] 2. The present invention uses a baffle plate and a baffle block at its upper end in conjunction with a reset spring. When the push block presses down on the vertical plate, the baffle block disengages from the filter hole to achieve drainage. After the push block resets, it automatically seals the filter hole to ensure that the wastewater does not leak during the flocculation reaction stage and that the water flows smoothly during the drainage stage.

[0019] 3. The present invention uses a scraper on the side of the pusher to rotate and connect within the slot, and with the stop block for limiting, it automatically adheres to the surface scraper when it moves down to contact the fixed plate, and automatically lifts up to avoid interference when it moves up to reset, thereby improving the thoroughness of impurity cleaning and operational stability.

[0028] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0029] In one embodiment, such as Figures 1-7 As shown, a wastewater treatment device for all-cotton spunlace nonwoven fabric includes a wastewater treatment tank 1, a collection tank 2, a drive structure 3, two sets of trajectory running structures 4, and a pusher block 5. A water inlet pipe 11 is fixed to the top of one side of the wastewater treatment tank 1, and a water outlet pipe 12 is fixed to the bottom of one side of the wastewater treatment tank 1. A fixing plate 16 is fixed inside the wastewater treatment tank 1. A discharge port 17 is provided through the connection between the side wall of the wastewater treatment tank 1 and one side of the fixing plate 16. The lowest end of the discharge port 17 is flush with the upper end of the fixing plate 16. A sealing door 24 is slidably installed inside the discharge port 17. Several filter holes 161 are provided through the fixing plate 16. The pusher 5 is installed inside the wastewater treatment tank 1 and is located on the upper end of the fixing plate 16. The collection box 2 is fixed to the front end of the wastewater treatment box 1. A collection tray 23 is slidably installed inside the collection box 2. A guide opening 21 is provided at the upper end of the collection box 2. An opening and closing structure 22 for controlling the opening and closing of the sealing door 24 is installed at the guide opening 21. The drive structure 3 is installed on the outer wall of the wastewater treatment tank 1. The drive structure 3 is connected to the trajectory running structure 4 and is used to drive the trajectory running structure 4 to move the push block 5. Two sets of trajectory running structures 4 are symmetrically installed on the two inner side walls of the wastewater treatment tank 1. Each trajectory running structure 4 includes a pulling unit 41 and a constraint unit 42. Both the pulling unit 41 and the constraint unit 42 are connected to the push block 5. The pulling unit 41 is connected to the driving structure 3. The pulling unit 41 is located inside the wastewater treatment tank 1 and is used to pull the push block 5 to move. The constraint unit 42 is located at the upper end of the wastewater treatment tank 1 and is used to constrain the movement trajectory of the push block 5. When the pusher 5 moves to the discharge port 17, the pusher 5 drives the opening and closing structure 22 to open the sealing door 24 at the discharge port 17, so as to discharge impurities into the collection drawer 23 inside the collection box 2.

[0030] In this embodiment, wastewater enters the wastewater treatment tank 1 through the inlet pipe 11 and undergoes a flocculation reaction above the fixed plate 16. The generated flocculent impurities are trapped on the upper surface of the fixed plate 16, and the treated water flows downward through the filter holes 161 and is finally discharged through the outlet pipe 12. The drive structure 3 drives two sets of trajectory running structures 4 to run synchronously. The pulling unit 41 pulls the push block 5 to move, while the constraint unit 42 limits the movement trajectory of the push block 5. The push block 5 first moves horizontally towards the discharge port 17, pushing the flocculent impurities on the fixed plate 16 forward. When the push block 5 moves to the discharge port 17, it touches the opening and closing structure 22, driving the opening and closing structure 22 to open the sealing door 24. The push block 5 continues to move forward, pushing the flocculent impurities through the discharge port 17 into the collection drawer 23 inside the collection box 2. Then the push block 5 moves in the opposite direction to reset, and the opening and closing structure 22 drives the sealing door 24 to close the discharge port 17 again, completing one working cycle.

[0031] In an optional embodiment, the pulling unit 41 includes a rotating block 411, a slide tube 412, a limiting block 413, a limiting ring 414, a return spring 415, a pull rod 416, and a rotating ring 417. The rotating block 411 is rotatably mounted on the inner side wall of the wastewater treatment tank 1, and the rotating block 411 is connected to the drive structure 3. A side sliding opening 4111 is provided through the side wall of the rotating block 411. The inner wall of the side sliding opening 4111 is slidably connected to the outer wall of the sliding tube 412. A limit block 413 is fixed to one end of the sliding tube 412, and a limit ring 414 is fixed to the other end of the sliding tube 412. A return spring 415 is fixed between the limit ring 414 and the rotating block 411. 5 is sleeved on the outside of the slide tube 412. The inner side wall of the hole of the limiting ring 414 is slidably connected to the outer side wall of the pull rod 416. One end of the pull rod 416 extends through the hole of the limiting ring 414 and extends into the inside of the slide tube 412 to be fixedly connected to the slider 4161. The outer side wall of the slider 4161 is slidably connected to the inner side wall of the slide tube 412. The other end of the pull rod 416 is fixedly connected to the rotating ring 417. The rotating ring 417 is rotatably sleeved on the outer side wall of the rotating shaft 54. The rotating shaft 54 ​​is fixedly installed on the side wall of the push block 5.

[0032] It should be noted that the drive structure 3 drives the rotating block 411 to rotate around its axis. The side sliding opening 4111 on the rotating block 411 is an oblique or radial long slot in which the slide tube 412 can slide. When the rotating block 411 rotates, the side sliding opening 4111 drives the slide tube 412 to make a circular motion. However, since the slide tube 412 is connected to the push block 5 through the pull rod 416, and the movement trajectory of the push block 5 is restricted by the constraint unit 42, the slide tube 412 must extend and retract radially along the side sliding opening 4111 while rotating with the rotating block 411. Specifically, when the push block 5 moves away from the rotating block 411 (for example, when the push block 5 is in the forward movement stage), the slide tube 412 is pulled out of the side sliding opening 4111, and the return spring 3 415 is compressed and stores energy; when the push block 5 moves closer to the rotating block 411 (for example, when the push block 5 is in the backward movement stage), the return spring 3 415 releases its elastic force and pushes the slide tube 412 back. Meanwhile, the pull rod 416 slides within the slide tube 412 via the slider 4161, further compensating for position changes. The rotational engagement between the rotating ring 417 and the rotating shaft 54 ​​ensures a flexible connection between the pull rod 416 and the push block 5 at all times.

[0033] The continuous rotational motion of the rotating block 411 is converted into the reciprocating motion of the push block 5 along a rectangular trajectory. Through the extension and retraction of the slide tube 412 and the elastic force of the return spring 415, the power is flexibly transmitted and the direction of motion is automatically switched when the push block 5 moves to the inflection point of the trajectory, thus avoiding jamming or impact caused by rigid transmission.

[0034] In an optional embodiment, the constraint unit 42 includes two fixing blocks 421, a constraint plate 422, a sleeve 423, and a constraint rod 424; Two fixing blocks 421 are symmetrically fixed on both sides of the upper end of the wastewater treatment tank 1. A constraint plate 422 is fixed between the two fixing blocks 421. A frame 423 is slidably fitted on the constraint plate 422. A constraint rod 424 is fixed at the lower end of the frame 423. The outer wall of the constraint rod 424 is slidably connected to the inner wall of the constraint opening 55. The constraint opening 55 is opened through the upper end of the push block 5.

[0035] It should be noted that the constraint plate 422 is horizontally fixed to the upper end of the wastewater treatment tank 1, and the sleeve 423 can slide back and forth along the constraint plate 422. The constraint rod 424 fixed at the lower end of the sleeve 423 is vertically inserted into the constraint opening 55 at the upper end of the push block 5, and the constraint rod 424 and the constraint opening 55 are in sliding fit. When the push block 5 moves, the constraint rod 424 restricts the freedom of the push block 5 along the direction of the constraint opening 55 (i.e., the lateral displacement of the push block 5 itself), and allows the push block 5 to move back and forth as a whole through the sliding of the sleeve 423 on the constraint plate 422. When the push block 5 needs to move up and down, the constraint opening 55 slides relative to the fixed constraint rod 424, thereby achieving vertical guidance.

[0036] In coordination with the pulling unit 41, the movement trajectory of the push block 5 is precisely defined as a rectangular closed path of "horizontal backward movement → vertical downward movement → horizontal forward movement → vertical upward movement". Among them, the constraint plate 422 and the sleeve 423 control the horizontal movement of the push block 5, and the constraint rod 424 and the constraint port 55 control the vertical movement of the push block 5. The combination of the two ensures that the push block 5 can accurately perform drainage, scraping, impurity removal and resetting actions in a predetermined sequence during operation.

[0037] In an optional embodiment, the drive structure 3 includes a motor 31, two sets of transmission units 32 and a rotating rod 33. The two sets of transmission units 32 are symmetrically installed on the outer side walls at both ends of the wastewater treatment tank 1, and the two sets of transmission units 32 are connected by the rotating rod 33. The transmission unit 32 includes a first transmission wheel 321, a transmission belt 322, and a second transmission wheel 323. The first transmission wheel 321 is rotatably mounted on the outer side wall of one end of the wastewater treatment tank 1, and the first transmission wheel 321 is fixedly connected to a rotating block 411 on the inner side wall of one end of the wastewater treatment tank 1. Two fixing ears 18 are symmetrically fixed on both sides of the rear end of the wastewater treatment tank 1. The second transmission wheel 323 is rotatably mounted on the fixing ears 18. The first transmission wheel 321 and the second transmission wheel 323 are connected by a transmission belt 322. The second transmission wheel 323 of this group of transmission units 32 is fixedly connected to the second transmission wheel 323 of another group of transmission units 32 by a rotating rod 33. The motor 31 is installed on the outer wall of the wastewater treatment tank 1, and the output end of the motor 31 is fixedly connected to the transmission wheel 321 located on the outer wall of the same wastewater treatment tank 1.

[0038] It should be noted that after the motor 31 starts, its output shaft drives the transmission wheel 321 on the same side to rotate. This transmission wheel 321 drives the transmission wheel 323 on the same side to rotate via the transmission belt 322. Since the two transmission wheels 323 are fixedly connected by a rotating rod 33, when one transmission wheel 323 rotates, the other transmission wheel 323 also rotates synchronously. The other transmission wheel 323 then drives the transmission wheel 321 on the other side to rotate via its corresponding transmission belt 322. Finally, the transmission wheels 321 on both sides drive the rotating blocks 411 on the inner walls of both sides of the wastewater treatment tank 1 to rotate synchronously.

[0039] Using a single motor 31, power is synchronously transmitted to the pulling units 41 on both sides of the wastewater treatment tank 1 through two symmetrically arranged transmission units 32 and rotating rods 33, ensuring that the rotating blocks 411 on the left and right sides rotate with the same angular velocity and phase. This ensures that the push block 5 is subjected to uniform force at both ends and moves synchronously, avoiding the push block 5 from tilting or jamming due to inconsistent movement on both sides, and enabling the push block 5 to run smoothly and accurately along the predetermined trajectory.

[0040] In an optional embodiment, a slot 51 is provided at the corner of the side and lower end of the push block 5, and a scraper 53 is provided inside the slot 51. The corner of the slot 51 and the side end of the push block 5 is rotatably connected to the corner of the scraper 53, and a stop block 52 is fixed at the corner inside the slot 51.

[0041] It should be noted that one corner of the scraper block 53 is rotatably connected to the corner of the slot 51, allowing the scraper block 53 to swing around this connection point within the slot 51. The abutment block 52 is fixed at the inner corner of the slot 51 to limit the angle of rotation of the scraper block 53 into the slot 51, preventing the scraper block 53 from completely retracting into the slot 51. When the pusher block 5 moves vertically downward from above and its lower end first contacts the upper surface of the fixing plate 16, the inclined surface of the scraper block 53 faces upward; the lower end of the scraper block 53 is in close contact with the upper surface of the fixing plate 16, scraping the trapped flocculent impurities forward. When the pusher block 5 completes the impurity removal and begins to move vertically upward to reset (i.e., gradually moving away from the upper surface of the fixing plate 16), the scraper block 53 loses the contact pressure with the fixing plate 16 and continues to rotate in the opposite direction around the axis under the action of gravity. Its inclined surface gradually turns vertical and maintains this posture under the obstruction of the abutment block 52, preventing the scraper block 53 from completely entering the slot 51. This cycle repeats to ensure that each time the push block 5 moves down and contacts the upper surface of the fixed plate 16, the inclined surface of the scraper block 53 always faces upward, preparing for the next scraping operation.

[0042] By utilizing the swing characteristics of the scraper block 53 and the limiting position of the stop block 52, the scraper block 53 automatically presses down and adheres to the surface of the fixed plate 16 during the working stroke to effectively scrape the material. During the reset stroke, it automatically lifts up and keeps the inclined surface vertical, avoiding interference or jamming between the scraper block 53 and the fixed plate 16. At the same time, it ensures that the scraper block 53 is in the correct initial posture at the beginning of each working cycle.

[0043] In an optional embodiment, the opening and closing structure 22 includes a contact plate 221, a slide bar 222, a return spring 223, a connecting plate 224, a guide plate 225, and a connecting rod 226. The contact plate 221 is disposed inside the wastewater treatment tank 1 and is located above the fixed plate 16. The rear side wall of the wastewater treatment tank 1 has several sliding openings 19, and a sliding rod 222 slides in each of the sliding openings 19. One end of the sliding rod 222 extends into the wastewater treatment tank 1 and is fixedly connected to the contact plate 221. The other end of the sliding rod 222 extends into the outside of the wastewater treatment tank 1 and is fixedly connected to the connecting plate 224. A second return spring 223 is fixed between the connecting plate 224 and the outer wall of the wastewater treatment tank 1. The second return spring 223 is sleeved on the outer side wall of the sliding rod 222. Several guide plates 225 are fixed at the lower end of the connecting plate 224. Each guide plate 225 slides with a guide opening 21. The lower end of the guide plate 225 extends through the guide opening 21 into the collection box 2. The guide plate 225 is fixedly connected to the sealing door 24 inside the collection box 2 by a connecting rod 226.

[0044] It should be noted that in the initial state, the second reset spring 223 is in its natural state, and the sealing door 24 closes the discharge port 17. When the push block 5 moves forward along the upper surface of the fixed plate 16 to the discharge port 17, the front end of the push block 5 first touches the contact plate 221 and pushes the contact plate 221 forward (towards the discharge port 17). The contact plate 221 drives the slide rod 222 to slide forward in the slide opening 19, and the slide rod 222 drives the connecting plate 224 to move forward synchronously, stretching the second reset spring 223. The guide plate 225 at the lower end of the connecting plate 224 moves forward accordingly, and the guide plate 225 drives the sealing door 24 to slide forward through the connecting rod 226, thereby opening the discharge port 17. At this time, the push block 5 continues to move forward, pushing the impurities into the collection box 2. After the pusher block 5 completes the discharge of impurities and moves upward and away from the contact plate 221, the contact plate 221 loses its pushing force, and the stretched reset spring 223 retracts and resets, pulling the connecting plate 224, slide rod 222, guide plate 225 and connecting rod 226 to move backward, causing the sealing door 24 to slide backward and re-close the discharge port 17.

[0045] By utilizing the movement of the pusher block 5 itself, the opening and closing of the sealing door 24 is automatically controlled through mechanical linkage. There is no need to set up an independent power source or sensor for the sealing door, which simplifies the equipment structure, reduces manufacturing costs and control complexity, and ensures that the timing of the pusher block 5 pushing impurities and the opening of the sealing door 24 are completely synchronized.

[0046] In an optional embodiment, a fixing frame 13 is fixed to the inner wall of the wastewater treatment tank 1. The fixing frame 13 is located directly below the fixing plate 16. A baffle plate 15 is provided between the fixing frame 13 and the fixing plate 16. The outer wall of the baffle plate 15 is slidably connected to the inner wall of the wastewater treatment tank 1. A plurality of baffle blocks 151 are fixed to the upper end of the baffle plate 15. Each baffle block 151 is slidably fitted with a filter hole 161 on the fixing plate 16. A plurality of water outlet holes 153 are provided through the baffle plate 15.

[0047] The upper end of the fixed frame 13 is fixedly connected to the lower end of the baffle plate 15 by a number of reset springs 14. Two vertical plates 152 are symmetrically fixed on both sides of the upper end of the baffle plate 15. Two vertical openings 162 are symmetrically opened through both sides of the upper end of the vertical plate 152. Each vertical plate 152 is slidably engaged with one vertical opening 162.

[0048] It should be noted that the fixing frame 13 is fixed to the inner wall of the wastewater treatment tank 1 and located directly below the fixing plate 16, and the baffle plate 15 is slidably disposed between the fixing frame 13 and the fixing plate 16. The lower ends of several return springs 14 are fixed to the upper end of the fixing frame 13, and the upper ends are fixedly connected to the lower end of the baffle plate 15, pushing the baffle plate 15 upward. In the initial state, the baffle plate 15 is lifted so that each of the baffle blocks 151 at its upper end is inserted into the corresponding filter holes 161 on the fixing plate 16, blocking the filter holes 161; at the same time, the vertical plates 152 on both sides of the baffle plate 15 pass upward through the vertical openings 162 on the fixing plate 16 and protrude from the upper surface of the fixing plate 16. When push block 5 moves downward and contacts vertical plate 152, push block 5 pushes vertical plate 152 downward, causing baffle plate 15 to move downward against the elastic force of return spring 14. Baffle block 151 is pulled out of filter hole 161, and filter hole 161 is opened. The treated water can flow downward through filter hole 161, the space below baffle plate 15, and the outlet hole 153 through baffle plate 15, and finally be discharged through outlet pipe 12. When push block 5 moves upward to reset and disengages from vertical plate 152, return spring 14 releases its elastic force, pushes baffle plate 15 upward to reset, baffle block 151 is reinserted into filter hole 161, and outlet hole 153 is offset from filter hole 161 as baffle plate 15 moves upward, stopping drainage.

[0049] The downward thrust of push block 5 controls the opening and closing of filter holes 161 via vertical plate 152, achieving sequential control of closing the filter holes during reaction and opening them during drainage, ensuring sufficient flocculation reaction and smooth drainage. Simultaneously, return spring 14 provides an automatic reset function, requiring no additional power source, resulting in a compact structure and reliable operation. The sliding fit between vertical plate 152 and vertical opening 162 guides the up-and-down movement of baffle plate 15, ensuring that baffle block 151 accurately inserts or withdraws from filter hole 161 each time.

[0050] A method for treating wastewater from spunlace nonwoven fabric manufacturing includes the following steps: Step 1: Flocculation reaction. Wastewater enters the wastewater treatment tank 1 through the inlet pipe 11. At this time, the filter holes 161 are blocked by the blocking block 151. The wastewater stays above the fixed plate 16. Flocculant is added to react and generate flocs. Step 2: Drainage is opened. The drive structure 3 drives the push block 5 to move horizontally backward and then vertically downward through the track running structure 4. The downward push block 5 pushes the vertical plate 152 to make the baffle plate 15 move downward. The baffle block 151 disengages from the filter hole 161. The treated water is discharged from the outlet pipe 12 through the filter hole 161 and the outlet hole 153. Step 3: Impurity pushing. After the pusher block 5 moves down to contact the fixed plate 16, it moves forward horizontally to push the flocculated material trapped on the fixed plate 16 toward the impurity discharge port 17. Step 4: Impurity discharge. As the pusher block 5 moves forward, it touches and drives the opening and closing structure 22, opening the sealing door 24 and pushing the lint into the impurity collection tray 23 of the collection box 2 through the impurity discharge port 17. Step 5: Reset. Driven by the trajectory running structure 4, the push block 5 first moves vertically upward and then horizontally backward, returning to its initial position. At the same time, the baffle plate 15 and the sealing door 24 automatically reset.

Make the vertical plate 152 pass through the vertical opening 162 on the fixing plate 16. Step 3: Install the opening and closing structure 22, fix the contact plate 221 to one end of the slide rod 222, slide the slide rod 222 into the sliding opening 19 on the side wall of the wastewater treatment tank 1, put the reset spring 223 on the outside of the slide rod 222 and abut against the connecting plate 224 and the outer wall of the wastewater treatment tank 1, fix the connecting plate 224 to the other end of the slide rod 222, fix the upper end of the guide plate 225 to the lower end of the connecting plate 224, and fix the lower end of the guide plate 225 to the sealing door 24 through the connecting rod 226; Step 4: Install the trajectory running structure 4.
