Description

Technical Field

[0001] This invention relates to the field of clean production technology, and in particular to a wastewater and waste gas treatment device for dyeing and printing. Background Technology

[0002] During production activities in the printing and dyeing industry, a large amount of wastewater and waste gas are generated. If this wastewater and waste gas are discharged without treatment, it will cause great pollution to the environment. Therefore, in order to protect the environment and achieve clean production, wastewater and waste gas treatment equipment is often used to purify the wastewater and waste gas.

[0003] Chinese patent CN108585248B discloses a wastewater and waste gas environmental protection treatment device, including a water collection tank. A first sleeve is fixedly connected to the top of the water collection tank. Support columns are fixedly connected to both sides of the top of the first sleeve. A second sleeve is fixedly connected to the top of the support columns. Threaded sleeves are fixedly connected to both sides of the top of the second sleeve. A scraper is movably connected to the top of the threaded sleeve. An inlet pipe is fixedly connected to one side of the scraper. A threaded rod is threadedly connected to the top of the scraper. This wastewater and waste gas environmental protection treatment device allows for easy insertion of a screen cylinder at the bottom of the inlet pipe into the water collection tank. The scrapers on both sides of the water collection pipe facilitate movable connection with the second sleeve. By feeding wastewater through the inlet pipe, large solid waste is screened and left behind. The threaded rod allows workers to manually install and remove the scraper and clean the screen cylinder, thus achieving convenient cleaning.

[0004] The aforementioned wastewater and waste gas environmental protection treatment equipment also has the following technical problems: During the sedimentation process of wastewater in the sedimentation tank, a certain amount of solid pollutants will adhere to the inner wall of the sedimentation tank. After a long time, these solid pollutants are prone to hardening and tightly adhering to the inner wall of the sedimentation tank, making it difficult for these solid pollutants to be discharged from the sedimentation tank, thus affecting the subsequent sedimentation treatment of wastewater in the sedimentation tank. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies where solid pollutants easily harden and adhere tightly to the inner wall of sedimentation tanks, making it difficult to remove these solid pollutants from the sedimentation tanks. Therefore, this invention proposes a wastewater and waste gas treatment device for dyeing and printing.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a wastewater and waste gas treatment device for dyeing and printing, comprising a water collection tank, an inlet pipe installed at the upper end of the water collection tank, an outlet pipe connected to the upper end of the side wall of the water collection tank, a sedimentation tank installed at the bottom of the inner wall of the water collection tank, a drain pipe connected to the side wall of the sedimentation tank, the drain pipe being fixedly connected to the water collection tank, and a cleaning structure provided on the inner wall of the water collection tank, the cleaning structure comprising a support, spikes for scraping hardened pollutants, and bristles for brushing off the scraped pollutants.

[0007] The effect achieved by the above components is that, by setting up a cleaning structure, hardened solid pollutants in the sedimentation tank can be cleaned, allowing the solid pollutants to be discharged from the sedimentation tank, thus ensuring that the sedimentation tank can properly treat wastewater.

[0008] Preferably, the bracket is fixedly connected to the inner wall of the water collection tank. A servo motor is mounted on the surface of the bracket. A rotating cylinder is fixedly connected to the output end of the servo motor. A circular plate is slidably connected to the inner wall of the rotating cylinder. A sliding rod is fixedly connected to the lower surface of the circular plate. The sliding rod slides through the rotating cylinder. The sliding rod has a regular hexagonal prism structure. A first spring is fixedly connected to the upper surface of the circular plate. The end of the first spring away from the circular plate is fixedly connected to the rotating cylinder. A transmission plate is fixedly connected to the lower end of the sliding rod. Two locking blocks are fixedly connected to the upper surface of the transmission plate. A locking plate is engaged with the upper surface of each locking block. The vertical cross-section of the plate is "L" shaped. A mounting plate is fixedly connected to the surface of the long arm of the plate. Several spikes are fixedly connected to the side of the mounting plate away from the plate. Several bristles are fixedly connected to the side of the mounting plate near the spikes. The bristles are slidably connected to the inner wall of the sedimentation tank. The spikes are divided into two groups, and the bristles are located between the two groups of spikes. Two sliding tubes are slidably sleeved on the surface of the transmission plate. A baffle is fixedly connected to the upper surface of the sliding tube. The vertical cross-section of the baffle is "L" shaped. The long arm of the baffle is slidably connected to the long arm of the plate. The first spring is always in a contracted state.

[0009] The aforementioned components achieve the following effect: the locking plate engages with the locking block, which in turn restricts the position of the locking plate and thus the mounting plate. The movement of the mounting plate causes the brush bristles to move and contact the inner wall of the sedimentation tank. Then, the servo motor is activated, and its output rotates, driving the rotating drum to rotate. Since the sliding rod has a regular hexagonal prism structure, the rotation of the rotating drum drives the sliding rod to rotate, which in turn drives the transmission plate to rotate. The locking block, with the help of the transmission plate, drives the locking plate to rotate, and the mounting plate, with the help of the locking plate, drives the spikes and brush bristles to move, thereby achieving the purpose of cleaning the inner wall of the sedimentation tank.

[0010] Preferably, the transmission plate is fixedly connected to a fixing plate at the position of each of the two slide tubes. The vertical cross-section of the fixing plate is U-shaped, and the vertical cross-section at the upper end of the fixing plate is arc-shaped. A second spring is fixedly connected to the side of the fixing plate near the slide tube, and the end of the second spring away from the fixing plate is fixedly connected to a baffle.

[0011] The effect achieved by the above components is as follows: when the second spring extends, the baffle will slide away from the fixed plate with the help of the tension of the second spring. At this time, the long arm of the baffle will contact the long arm of the clamping plate, and the second spring will prevent the long arm of the baffle from disengaging from the long arm of the clamping plate as much as possible.

[0012] Preferably, a traction rope is fixedly connected to the upper surface of the baffle, and a ball is fixedly connected to the end of the traction rope away from the baffle, the size of the ball being adapted to the size of the fixed plate.

[0013] The effect achieved by the above components is as follows: pulling the ball causes the ball to move, which in turn causes the traction rope to move, and the movement of the traction rope causes the baffle to move closer to the fixed plate.

[0014] Preferably, the spikes are made of high-carbon steel and the bristles are made of polypropylene.

[0015] The effect achieved by the above-mentioned components is that, since the spikes are made of high-carbon steel, which has advantages such as high hardness, high strength and resistance to deformation, the spikes made of high-carbon steel can scrape off the hardened solid pollutants attached to the inner wall of the sedimentation tank.

[0016] Preferably, the inner wall of the water collection tank is provided with an auxiliary structure, the auxiliary structure including a mounting frame, the mounting frame being fixedly connected to the inner wall of the water collection tank, two connecting plates being fixedly connected to the lower surface of the mounting frame, the vertical cross-section of the connecting plates being "T"-shaped, a ring being rotatably connected to the surfaces of the two connecting plates, a plurality of protrusions being fixedly connected to the lower surface of the ring, the vertical cross-section of the lower end of the protrusions being isosceles triangles, two round rods being fixedly connected to the upper surface of the transmission plate, a stepper motor being fixedly connected to the lower surface of the mounting frame, a lever being fixedly connected to the output end of the stepper motor, a T-shaped plate being fixedly connected to the arc surface of the ring, two driven rods being fixedly connected to the lower surface of the T-shaped plate, and the lever being located between the two driven rods.

[0017] The effect achieved by the above-mentioned components is that by setting up an auxiliary structure, the spikes and bristles can vibrate continuously during rotation, thereby cleaning the solid pollutants attached to the inner wall of the water collection tank and thus improving the cleaning efficiency.

[0018] Preferably, the driven rod is rotatably connected to a roller, which is made of stainless steel.

[0019] The effect achieved by the above components is as follows: the rotation of the paddle will squeeze the roller, the roller will rotate along the arc surface of the driven rod and drive the driven rod to move. The roller reduces the friction between the arc surface of the driven rod and the paddle, and the stainless steel roller is also corrosion resistant and has a long service life.

[0020] Preferably, a bent plate is fixedly connected to the side wall of the lever, and the cross-sections at both ends of the bent plate are arc-shaped.

[0021] The effect achieved by the above components is that the bending plate helps to prevent the roller and the lever from losing contact as much as possible.

[0022] Preferably, the mounting bracket is provided with a limiting structure relative to the ring. The limiting structure includes a support plate, which is fixedly connected to the mounting bracket. A support tube is fixedly connected to the lower surface of the support plate. An electric telescopic rod is fixedly connected to the inner wall of the support tube. A push plate is fixedly connected to the output end of the electric telescopic rod. Two inserts are engaged inside the push plate. Rubber pads are fixedly connected to the side of the two inserts near the ring.

[0023] The effect achieved by the above components is as follows: by setting a limiting structure, the position of the ring is restricted, and the ring is prevented from rotating along the surface of the fixed plate as much as possible, thereby restricting the position of the protrusion.

[0024] Preferably, a guide plate is fixedly connected to the upper surface of the push plate, the vertical cross-section of the guide plate is "L" shaped, and the long arm of the guide plate passes through the support plate.

[0025] The effect achieved by the above components is that when the push plate slides, it will drive the guide plate to slide along the inside of the support plate. The guide plate restricts the sliding path of the push plate and prevents the push plate from rotating as much as possible.

[0026] Compared with the prior art, the advantages and positive effects of the present invention are as follows:

[0027] 1. In this invention, by setting a cleaning structure, before cleaning the sedimentation tank, the ball is first pulled. The movement of the ball will drive the traction rope to move, which in turn will drive the baffle to move closer to the fixed plate. The movement of the baffle will cause the slide tube to slide along the surface of the transmission plate. At this time, the transmission plate will restrict the sliding path of the slide tube. When the baffle slides, it will squeeze the second spring. At this time, the second spring is in a compressed state. After the long arm of the baffle moves away from the top of the locking block, the ball continues to move so that the traction rope slides into the inner wall of the fixed plate. At this time, the fixed plate will restrict the position of the ball and thus restrict the position of the baffle. Setting the upper end of the fixed plate into an arc shape can prevent the ball from losing contact with the fixed plate as much as possible. Then, the locking plate locks the locking block. At this time, the locking block will restrict the position of the locking plate and thus restrict the position of the mounting plate. The movement of the mounting plate will drive the brush to move so that the brush contacts the inner wall of the sedimentation tank. Then, the ball is pulled so that the traction rope slides out from the inner wall of the fixed plate. At this time, the second spring begins to extend, and the baffle will slide away from the fixed plate with the help of the tension of the second spring. When the baffle arm contacts the clamping plate arm, the baffle restricts the clamping plate's position, preventing it from disengaging from the clamping block. Then, the servo motor starts rotating, driving the drum. Since the slide rod is a regular hexagonal prism, the drum's rotation drives the slide rod, which in turn drives the transmission plate. The clamping block, via the transmission plate, drives the clamping plate, and the mounting plate, via the clamping plate, moves the spikes and brushes. The spikes, made of high-carbon steel (which has high hardness, high strength, and resistance to deformation), scrape away hardened solid pollutants adhering to the sedimentation tank's inner wall. The polypropylene brushes then brush off the scraped solid pollutants, effectively removing them from the sedimentation tank. This cleaning structure effectively removes hardened solid pollutants from the sedimentation tank, ensuring its proper function in treating wastewater.

[0028] 2. In this invention, by setting an auxiliary structure, when the transmission plate rotates, it drives the round rod to rotate. The rotating round rod contacts the inclined surface at the lower end of the protrusion. At this time, the protrusion squeezes the round rod, causing it to slide downwards. The transmission plate, with the help of the sliding round rod, drives the sliding rod to slide. The sliding rod drives the round plate to slide along the inner wall of the rotating cylinder. At this time, the round plate stretches the first spring. The first spring is in a stretched state. As the servo motor continues to rotate, it causes the round rod to disengage from the protrusion. At this time, the first spring begins to contract, and the round plate slides upwards with the help of the tension of the first spring. The sliding of the round plate drives the sliding rod to slide, ultimately causing the spikes and bristles to slide vertically while rotating. Therefore, the continuous rotation of the servo motor enables the spikes and bristles to vibrate while rotating, thereby better cleaning solid contaminants. During the cleaning process, the stepper motor is started, and the output end of the stepper motor will... The rotating paddle contacts the arc surface of the roller, causing it to press against the roller. The roller then rotates along the arc surface of the driven rod, moving the driven rod. This reduces friction between the roller and the paddle. The stainless steel roller is also corrosion-resistant and has a long service life. The T-shaped plate, moving with the driven rod, rotates the ring along the surface of the connecting plate. This rotation of the ring causes the protrusions to rotate, adjusting their position and thus the starting position of the spikes and bristles. This allows the spikes and bristles to clean different areas within the sedimentation tank. During this process, the bending plate prevents the roller from disengaging from the paddle. By incorporating auxiliary structures, the spikes and bristles continue to vibrate during rotation, effectively cleaning solid contaminants adhering to the inner wall of the collection tank, thereby improving cleaning efficiency.

[0029] 3. In this invention, by setting a limiting structure, when the limiting structure is needed, the insert block is first engaged with the push plate. At this time, the insert block restricts the position of the rubber pad. After adjusting the ring to a suitable position with the help of the lever, the electric telescopic rod is activated. At this time, the output end of the electric telescopic rod will drive the push plate to move closer to the ring. The movement of the insert block with the help of the push plate will drive the rubber pad to move, so that the rubber pad abuts against the arc surface of the ring. At this time, the rubber pad increases the friction between the push plate and the ring. The push plate restricts the position of the ring, preventing the ring from rotating along the surface of the fixed plate as much as possible, thereby restricting the position of the protrusion. When the push plate slides, it will drive the guide plate to slide along the inside of the support plate. The guide plate restricts the sliding path of the push plate and prevents the push plate from rotating as much as possible. By setting a limiting structure, the position of the ring is restricted, preventing the ring from rotating along the surface of the fixed plate as much as possible, thereby restricting the position of the protrusion.

[0041] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described below in conjunction with the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0042] Numerous specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways than those described herein, and therefore the invention is not limited to the specific embodiments disclosed in the following specification.

[0043] Example 1, such as Figure 1 and Figure 2 as well as Figure 3 As shown, this invention provides a wastewater and waste gas treatment device for dyeing and printing, including a water collection tank 1. An inlet pipe 2 is installed at the upper end of the water collection tank 1, and an outlet pipe 3 is connected to the upper end of the side wall of the water collection tank 1. A sedimentation tank 5 is installed at the bottom of the inner wall of the water collection tank 1, and a drain pipe 4 is connected to the side wall of the sedimentation tank 5. The drain pipe 4 is fixedly connected to the water collection tank 1. A cleaning structure 6 is provided on the inner wall of the water collection tank 1. By setting the cleaning structure 6, hardened solid pollutants in the sedimentation tank 5 can be cleaned, allowing the solid pollutants to be discharged from the sedimentation tank 5, ensuring that the sedimentation tank 5 can properly treat the wastewater. An auxiliary structure 7 is provided on the inner wall of the water collection tank 1. By setting the auxiliary structure 7, the spikes 611 and bristles 612 can continuously vibrate during rotation, thereby cleaning the solid pollutants adhering to the inner wall of the water collection tank 1 and improving the cleaning efficiency. The mounting bracket 701 is provided with a limiting structure 8 relative to the ring 703. By setting the limiting structure 8, the position of the ring 703 is restricted, and the ring 703 is prevented from rotating along the surface of the fixing plate 615 as much as possible, thereby limiting the position of the protrusion 704.

[0044] The following section will explain the specific settings and functions of its cleaning structure 6, auxiliary structure 7, and limiting structure 8.

[0045] like Figure 4-7As shown, the cleaning structure 6 includes a bracket 601, spikes 611 for scraping hardened contaminants, and bristles 612 for brushing away the scraped contaminants. The bracket 601 is fixedly connected to the inner wall of the water collection tank 1. A servo motor 602 is mounted on the surface of the bracket 601. A rotating drum 603 is fixedly connected to the output end of the servo motor 602. A circular plate 604 is slidably connected to the inner wall of the rotating drum 603. A sliding rod 605 is fixedly connected to the lower surface of the circular plate 604, sliding through the rotating drum 603. The sliding rod 605 has a regular hexagonal prism structure. A first spring 606 is fixedly connected to the upper surface of the circular plate 604. The end of the first spring 606 away from the circular plate 604 is fixedly connected to the rotating drum 603. The lower end of the sliding rod 605... A transmission plate 607 is fixedly connected to the end of the sedimentation tank 5. Two locking blocks 608 are fixedly connected to the upper surface of the transmission plate 607. A locking plate 609 is engaged with the upper surface of the locking blocks 608. The vertical cross-section of the locking plate 609 is "L"-shaped. A mounting plate 610 is fixedly connected to the surface of the long arm of the locking plate 609. Several spikes 611 are fixedly connected to the side of the mounting plate 610 away from the locking plate 609. Several bristles 612 are fixedly connected to the side of the mounting plate 610 near the spikes 611. The bristles 612 are slidably connected to the inner wall of the sedimentation tank 5. The spikes 611 are divided into two groups. Several bristles 612 are located between two sets of spikes 611. Two sliding tubes 613 are slidably fitted onto the surface of the transmission plate 607. A baffle 614 is fixedly connected to the upper surface of each sliding tube 613. The vertical cross-section of the baffle 614 is L-shaped. The long arm of the baffle 614 is slidably connected to the long arm of the clamping plate 609. The first spring 606 is always in a contracted state, engaging the clamping plate 609 with the clamping block 608. At this time, the clamping block 608 restricts the position of the clamping plate 609, thereby restricting the position of the mounting plate 610. Movement of the mounting plate 610 will cause the bristles 612 to move. When the bristles 612 come into contact with the inner wall of the sedimentation tank 5, the servo motor 602 is activated. The output end of the servo motor 602 starts to rotate and drives the rotating drum 603 to rotate. Since the slide rod 605 has a regular hexagonal prism structure, the rotation of the rotating drum 603 will drive the slide rod 605 to rotate. The rotation of the slide rod 605 will drive the transmission plate 607 to rotate. The locking block 608, with the help of the transmission plate 607, will drive the locking plate 609 to rotate. The mounting plate 610, with the help of the locking plate 609, will drive the spikes 611 and the bristles 612 to move, thereby achieving the purpose of cleaning the inner wall of the sedimentation tank 5.

[0046] like Figure 4 and Figure 5 as well as Figure 6As shown, the transmission plate 607 is fixedly connected to a fixing plate 615 at the position of each of the two slide tubes 613. The vertical cross-section of the fixing plate 615 is U-shaped, and the vertical cross-section of the upper end of the fixing plate 615 is arc-shaped. A second spring 616 is fixedly connected to the side of the fixing plate 615 near the slide tube 613. The end of the second spring 616 away from the fixing plate 615 is fixedly connected to the baffle 614. When the second spring 616 extends, the baffle 614 will slide away from the fixing plate 615 with the help of the tension of the second spring 616. At this time, the long arm of the baffle 614 will contact the long arm of the clamping plate 609. The second spring 616 achieves the function of preventing the long arm of the baffle 614 from disengaging from the long arm of the clamping plate 609 as much as possible. A traction rope 617 is fixedly connected to the upper surface of the baffle 614. A ball 618 is fixedly connected to the end of the traction rope 617 away from the baffle 614. The size of the ball 618 matches the size of the fixed plate 615. Pulling the ball 618 moves the traction rope 617, which in turn moves the baffle 614 closer to the fixed plate 615. The spikes 611 are made of high-carbon steel, and the bristles 612 are made of polypropylene. Because the spikes 611 are made of high-carbon steel, which has advantages such as high hardness, high strength, and resistance to deformation, the high-carbon steel spikes 611 can scrape off hardened solid pollutants adhering to the inner wall of the sedimentation tank 5.

[0047] like Figure 8 and Figure 9 As shown, the auxiliary structure 7 includes a mounting bracket 701, which is fixedly connected to the inner wall of the water collection tank 1. Two connecting plates 702 are fixedly connected to the lower surface of the mounting bracket 701. The vertical cross-section of the connecting plates 702 is "T" shaped. A ring 703 is rotatably connected to the surface of the two connecting plates 702. Several protrusions 704 are fixedly connected to the lower surface of the ring 703. The vertical cross-section of the lower end of the protrusions 704 is an isosceles triangle. Two round rods 705 are fixedly connected to the upper surface of the transmission plate 607. A stepper motor 706 is fixedly connected to the lower surface of the mounting bracket 701. A lever 707 is fixedly connected to the output end of the stepper motor 706. A T-shaped plate 708 is fixedly connected to the arc surface of the ring 703. Two driven rods 709 are fixedly connected to the lower surface of the T-shaped plate 708. The lever 707 is located between the two driven rods 709. A roller 710, made of stainless steel, is rotatably connected to the arc surface of the driven rod 709. When the lever 707 rotates, it presses against the roller 710, causing the roller 710 to rotate along the arc surface of the driven rod 709 and move the driven rod 709. The roller 710 reduces the friction between the arc surface of the driven rod 709 and the lever 707. Furthermore, the stainless steel roller 710 is corrosion-resistant and has a long service life. A bent plate 711 is fixedly connected to the side wall of the lever 707. Both ends of the bent plate 711 have arc-shaped cross-sections, which helps to prevent the roller 710 from disengaging from the lever 707.

[0048] like Figure 8 and Figure 10 As shown, the limiting structure 8 includes a support plate 81, which is fixedly connected to the mounting bracket 701. A support tube 82 is fixedly connected to the lower surface of the support plate 81, and an electric telescopic rod 83 is fixedly connected to the inner wall of the support tube 82. A push plate 84 is fixedly connected to the output end of the electric telescopic rod 83. Two inserts 85 are engaged inside the push plate 84, and rubber pads 86 are fixedly connected to the side of the two inserts 85 near the ring 703. A guide plate 87 is fixedly connected to the upper surface of the push plate 84. The vertical cross-section of the guide plate 87 is "L"-shaped, and the long arm of the guide plate 87 passes through the support plate 81. When the push plate 84 slides, it will drive the guide plate 87 to slide along the inside of the support plate 81. The guide plate 87 restricts the sliding path of the push plate 84 and prevents the push plate 84 from rotating as much as possible.

[0049] The overall working principle is as follows: Before cleaning the sedimentation tank 5, the ball 618 is pulled. The movement of the ball 618 will drive the traction rope 617 to move. The movement of the traction rope 617 will drive the baffle 614 to move closer to the fixed plate 615. The movement of the baffle 614 will drive the slide tube 613 to slide along the surface of the transmission plate 607. At this time, the transmission plate 607 will restrict the sliding path of the slide tube 613. When the baffle 614 slides, it will squeeze the second spring 616. At this time, the second spring 616 is in a compressed state. After the long arm of the baffle 614 moves away from the top of the locking block 608, the ball 618 continues to move. 18. The traction rope 617 slides into the inner wall of the fixed plate 615. At this time, the fixed plate 615 restricts the position of the ball 618 and thus restricts the position of the baffle 614. The upper end of the fixed plate 615 is set into an arc shape to prevent the ball 618 from losing contact with the fixed plate 615 as much as possible. Then, the locking plate 609 locks the locking block 608. At this time, the locking block 608 restricts the position of the locking plate 609 and thus restricts the position of the mounting plate 610. The movement of the mounting plate 610 will drive the brush bristles 612 to move and make the brush bristles 612 contact the inner wall of the sedimentation tank 5. Then, the ball 618 is pulled, so that the traction rope 617 moves from the fixed plate 615. The inner wall of the fixed plate 615 slides out, at which point the second spring 616 begins to extend. The baffle 614, aided by the tension of the second spring 616, slides away from the fixed plate 615. At this point, the long arm of the baffle 614 contacts the long arm of the clamping plate 609, thus limiting the position of the clamping plate 609 and preventing it from disengaging from the clamping block 608. Then, the servo motor 602 is activated, and its output begins to rotate, driving the rotating drum 603 to rotate. Since the slide rod 605 has a regular hexagonal prism structure, the rotation of the rotating drum 603 will drive the slide rod 605 to rotate. The movement of the drive plate 607 causes the clamping block 608 to rotate, which in turn causes the clamping plate 609 to rotate. The mounting plate 610, in turn, causes the spikes 611 and brushes 612 to move. Since the spikes 611 are made of high-carbon steel, which has advantages such as high hardness, high strength and resistance to deformation, the high-carbon steel spikes 611 can scrape off the hardened solid pollutants attached to the inner wall of the sedimentation tank 5. Then, the polypropylene brushes 612 can brush off the scraped solid pollutants, thereby achieving the function of discharging solid pollutants from the sedimentation tank 5.

[0050] When the transmission plate 607 rotates, it drives the round rod 705 to rotate. The rotating round rod 705 contacts the inclined surface at the lower end of the protrusion 704. At this time, the protrusion 704 presses against the round rod 705, causing it to slide downwards. The transmission plate 607, aided by the sliding of the round rod 705, drives the sliding rod 605 to slide. The sliding rod 605 then drives the round plate 604 to slide along the inner wall of the rotating cylinder 603. At this time, the round plate 604 stretches the first spring 606, which is in a stretched state. As the servo motor 602 continues to rotate, the round rod 705 disengages from the protrusion 704. At this point, the first spring 606 begins to contract, and the round plate 604 slides upwards with the help of the tension of the first spring 606. The sliding of the round plate 604 causes the sliding rod 605 to slide, ultimately causing the spike 611 and bristles 612 to slide vertically while rotating. Therefore, the continuous rotation of the servo motor 602 enables the spike 611 and bristles 612 to vibrate while rotating, thereby better removing solid contaminants. During cleaning, stepper motor 706 is started. The output of stepper motor 706 drives the paddle 707 to rotate. The rotating paddle 707 contacts the arc surface of roller 710, at which point the paddle 707 presses against roller 710. Roller 710 rotates along the arc surface of driven rod 709, driving driven rod 709 to move. Roller 710 reduces the friction between the arc surface of driven rod 709 and paddle 707. Furthermore, the stainless steel roller 710 is corrosion-resistant and has other properties. With a long service life, the T-shaped plate 708 moves with the help of the driven rod 709, which drives the ring 703 to rotate along the surface of the connecting plate 702. The rotation of the ring 703 drives the protrusion 704 to rotate, thereby adjusting the position of the protrusion 704, and then adjusting the position where the spike 611 and the bristles 612 start to vibrate, so that the spike 611 and the bristles 612 can clean different positions in the sedimentation tank 5. During this process, the bending plate 711 achieves the function of preventing the roller 710 from losing contact with the paddle 707 as much as possible.

[0051] When the limiting structure 8 is required, first engage the insert block 85 with the push plate 84. At this time, the insert block 85 restricts the position of the rubber pad 86. After adjusting the ring 703 to a suitable position with the help of the lever 707, start the electric telescopic rod 83. At this time, the output end of the electric telescopic rod 83 will drive the push plate 84 to move closer to the ring 703. The movement of the insert block 85 with the help of the push plate 84 will drive the rubber pad 86 to move, so that the rubber pad 86 abuts against the arc surface of the ring 703. At this time, the rubber pad 86 increases the friction between the push plate 84 and the ring 703. The push plate 84 restricts the position of the ring 703 and prevents the ring 703 from rotating along the surface of the fixed plate 615 as much as possible, thereby restricting the position of the protrusion 704. When the push plate 84 slides, it will drive the guide plate 87 to slide along the inside of the support plate 81. The guide plate 87 restricts the sliding path of the push plate 84 and prevents the push plate 84 from rotating as much as possible.
