[0001] The present invention relates to the technical field of sewage treatment, in particular to a fabric printing and dyeing sewage treatment device. Background Art

[0002] The sewage treatment device of fabric printing and dyeing equipment is a device for treating sewage generated by fabric printing and dyeing. It is designed to perform secondary processing on sewage to avoid the impact of sewage leakage on the environment.

[0003] The patent with patent announcement number CN208413954U involves a dosing device, which is arranged inside a box. The dosing device includes a dosing device and a mixer. The dosing device and the mixer are both tubular, and their inlet ends are both arranged outside the box. The outlet end of the mixer is connected to the dosing device, and the outlet end of the dosing device is connected to the flocculation device. The mixer is arranged in a curved shape, and its curved structure extends the mixing path of sewage and chemicals. The sewage treatment device saves floor space while ensuring sufficient mixing of sewage and chemicals, and has a simple structure.

[0004] In the above patent, the sewage treatment device saves floor space while ensuring sufficient mixing of sewage and chemicals. The structure is simple, but there are still problems. When the chemicals are in contact with sewage, the volumes of the chemicals and liquid cannot be effectively proportional. At the same time, it is also impossible to ensure that the amount of chemicals is the same each time. This difficulty will affect subsequent operations. Summary of the Invention

[0005] In view of the deficiencies in the prior art, the present invention provides a fabric printing and dyeing wastewater treatment device, which solves the problems raised in the above-mentioned background technology.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solutions: A fabric printing and dyeing wastewater treatment device, comprising a body, a motor is provided at the bottom of the body, a main shaft is fixedly mounted on the output end of the motor, a reciprocating spiral groove is provided on the circumferential surface of the top of the main shaft, a stirring rod is fixedly mounted on the circumferential surface of the main shaft, and a medicine mechanism is provided on the left side of the body; The medicine mechanism includes a moving rod, a right-angle rod, a flat ring rod, a round steel rod, a ring plate, a feed tube and a medicine box. One end of the moving rod is slidably mounted in the spiral groove of the main shaft, the right-angle rod is fixedly mounted on the top of the other end of the moving rod, the flat ring rod is fixedly mounted on the top of the right-angle rod, the round steel rod is slidably mounted inside the flat ring rod, the medicine box is fixedly mounted on the left side of the machine body, the ring plate is fixedly mounted on the bottom of the medicine box, the feed tube is rotatably mounted inside the ring plate, and a slide groove is provided at the bottom of the medicine box. Among them, the front of the body is provided with a quick installation mechanism and the interior of the body is provided with a primary filtering mechanism. When the right-angle rod moves up and down, it will drive the flat ring rod to move up and down. When the flat ring rod moves up and down, it will drive the round steel rod to move left and right. When the round steel rod moves left and right, it will drive the fixed material tube inside the ring plate to rotate.

[0007] According to the above technical solution, the medicine mechanism also includes an L-rod, a rotating plate, a telescopic plate and a spacer rod. The fixed end of the telescopic plate is arranged inside the slide groove, the rotating plate is rotatably installed on the free end of the telescopic plate, and the L-rod is fixedly installed on the side of the flat ring rod close to the ring plate. The L-rod is fixedly connected to the rotating plate. When the rotating plate moves up and down, the telescopic plate will be separated. When the telescopic plate is separated and combined, the spacer rod will move repeatedly, thereby breaking up the medicine inside the medicine box.

[0008] According to the above technical solution, the round steel rod is rotatably connected to the dosing tube, and the spacer rod is fixedly installed on the free end of the telescopic plate. When the round steel rod moves left and right, it will drive the dosing tube inside the ring plate to rotate. When the dosing tube rotates one circle, a part of the medicine inside the upper medicine box will be poured out into the body, thereby realizing quantitative dosing.

[0009] According to the above technical solution, the installation mechanism includes a push rod, a pressure rod, a sponge frame, a U rod and a ladder block. The push rod is slidably installed on the left side of the body, the sponge frame is fixedly installed on the front of the body, the pressure rod is slidably installed inside the sponge frame, the U rod is slidably installed on the front of the body, and the ladder block is slidably installed inside the U rod. When the U rod moves, it will drive the primary screening plate to move. When the primary screening plate moves, it will drive the double rotating rod to move. When the double rotating rod moves, the primary screening plate will be limited for a second time.

[0010] According to the above technical solution, the installation mechanism also includes a three-rotating rod, a double-rotating rod and a primary screening plate. The three-rotating rod is rotatably installed on the top of the U rod, the double-rotating rod is rotatably installed on the bottom of the three-rotating rod, and the primary screening plate is slidably installed inside the machine body. When the primary screening plate needs to be taken out, it is only necessary to pull the three-rotating rod downward, which will cause the U rod to move outward and the double-rotating rod to move upward, thereby releasing the limit on the primary screening plate.

[0011] According to the above technical solution, the flat ring rod is in contact with the push rod, the push rod is in contact with the pressure rod, the ladder block is in contact with the primary screening plate, tooth grooves are provided on both sides of the primary screening plate, and a No. 1 spring is provided between the U rod and the ladder block. When the staff inserts the primary screening plate into the machine body, the gap of the machine body is too small. In order to avoid the staff from being unable to accurately insert the primary screening plate, the ladder block can effectively provide guidance for the staff to insert the primary screening plate.

[0012] According to the above technical solution, the primary filtering mechanism includes a gear, a semicircular rod, a roller, a moving block, a reciprocating screw, a scraper, a thin rod, a moving ring, a wire box, a connecting rod, a ring and a rubber ring. The gear is rotatably mounted on the inner wall of the body, the semicircular rod is slidably mounted on the inner wall of the body, the roller is rotatably mounted on the inner wall of the body, two semicircular pieces are provided on the outside of the roller, a tooth block is provided on the semicircular piece, the reciprocating screw is fixedly mounted on the side of the gear close to the roller, the moving block is slidably mounted in the spiral groove of the reciprocating screw, and one end of the connecting rod is fixed It is installed on the top of the moving block, the circular ring is fixedly installed on the other end of the connecting rod, the wire box is fixedly installed on the right side of the machine body, the rubber ring is fixedly installed at the junction of the wire box and the machine body, the scraper is slidably installed on the right side of the machine body, one end of the thin rod is rotatably installed on the end of the scraper away from the roller, and the moving ring is rotatably installed on the other end of the thin rod. When the circular ring moves, it will push the line above the roller. At the same time, the width of the circular ring is greater than the distance between each two tooth blocks, so when the circular ring moves to the position of the rubber ring, it will press the last block to prevent the tooth block from protruding.

[0013] According to the above technical solution, the gear is engaged with the semicircular rod, the width of the circular ring is greater than the spacing between the tooth blocks, the circular ring is in contact with the rubber ring, and the circular ring is in contact with the movable ring. When the scraper moves, it will move closer to the middle. When the next primary screening plate is inserted, the circular ring will exit the wire box. When the circular ring exits the wire box, the scraper will scrape out the lines above the circular ring.

[0014] The present invention provides a fabric printing and dyeing wastewater treatment device. It has the following beneficial effects: (1) In this invention, when the metering tube rotates one circle, a part of the medicine in the upper medicine box will be poured out into the body, thereby achieving quantitative feeding of medicine. When the telescopic plate opens and closes, the spacer rod will move repeatedly, thereby breaking up the medicine inside the medicine box, which can effectively break up the agglomeration or stratification of the medicine, allowing the chemical agent to fully contact with the sewage, ensuring the uniformity of the subsequent treatment reaction, avoiding its accumulation at the bottom of the medicine box, and maintaining the stability of the medicine concentration.

[0015] (2) This invention squeezes the sponge inside the sponge frame to squeeze out the liquid in the sponge, preventing the sponge from being unable to wipe the primary screening plate and preventing the staff from being unable to accurately insert the primary screening plate. Therefore, the ladder block can effectively provide guidance for personnel to insert the primary screening plate, reducing the difficulty of manual alignment, especially in narrow or limited-viewing spaces, reducing operation time and physical exertion, preventing wear and deformation of the primary screening plate and the body due to forced insertion or misplaced installation, and extending the service life of the equipment.

[0016] (3) In this invention, when the primary screen plate is pulled out, it drives the gear to rotate. When the gear rotates, it collects the lines in the liquid. When the next primary screen plate is inserted, the ring will exit the wire box. When the ring exits the wire box, the scraper will scrape out the lines above the ring, reducing the need for manual cleaning of the wire box. This is especially true for processing scenarios such as those involving sticky chemicals or easily agglomerated substances. It extends the continuous operation time of the equipment and prevents residual lines from accumulating at the sealing interface, which may cause chemical leakage or internal corrosion of the equipment.

[0024] See also Figures 1-9 On the basis of the above embodiment, in another embodiment of the present invention, a quick-install installation mechanism is provided on the front of the body 1 and a primary filtering mechanism is provided inside the body 1. The installation mechanism includes a push rod 601, a pressure rod 602, a sponge frame 603, a U rod 604 and a ladder block 605. The push rod 601 is slidably installed on the left side of the body 1, the sponge frame 603 is fixedly installed on the front of the body 1, the pressure rod 602 is slidably installed inside the sponge frame 603, the U rod 604 is slidably installed on the front of the body 1, and the ladder block 605 is slidably installed inside the U rod 604, which reduces the difficulty of manual alignment, especially in a narrow space or one with limited vision, reduces operation time and physical exertion, prevents wear and deformation of the primary screening plate 608 and the body 1 due to forced insertion or misplaced installation, and extends the service life of the equipment.

[0025] The installation mechanism also includes a three-rotating rod 606, a double-rotating rod 607 and a primary screening plate 608. The three-rotating rod 606 is rotatably installed on the top of the U rod 604, the double-rotating rod 607 is rotatably installed on the bottom of the three-rotating rod 606, and the primary screening plate 608 is slidably installed inside the body 1. When the primary screening plate 608 needs to be taken out, it is only necessary to pull the three-rotating rod 606 downward, which will cause the U rod 604 to move outward and the double-rotating rod 607 to move upward, thereby releasing the limit on the primary screening plate 608.

[0026] The flat ring rod 503 contacts the push rod 601, the push rod 601 contacts the pressure rod 602, the ladder block 605 contacts the primary screening plate 608, and there are tooth grooves on both sides of the primary screening plate 608. A No. 1 spring is arranged between the U rod 604 and the ladder block 605. When the staff inserts the primary screening plate 608 into the body 1, the gap of the body 1 is too small. In order to avoid the staff from being unable to accurately insert the primary screening plate 608, the ladder block 605 can effectively provide guidance for the staff to insert the primary screening plate 608.

[0027] The primary filtering mechanism includes a gear 701, a semicircular rod 702, a roller 703, a moving block 704, a reciprocating screw rod 705, a scraper 706, a thin rod 707, a moving ring 708, a wire box 709, a connecting rod 710, a ring 711 and a rubber ring 712. The gear 701 is rotatably mounted on the inner wall of the body 1, the semicircular rod 702 is slidably mounted on the inner wall of the body 1, the roller 703 is rotatably mounted on the inner wall of the body 1, two semicircular pieces are provided on the outside of the roller 703, and a tooth block is provided on the semicircular piece. The reciprocating screw rod 705 is fixedly mounted on the side of the gear 701 close to the roller 703, the moving block 704 is slidably mounted in the spiral groove of the reciprocating screw rod 705, and one end of the connecting rod 710 is fixed. It is installed on the top of the moving block 704, the circular ring 711 is fixedly installed on the other end of the connecting rod 710, the wire box 709 is fixedly installed on the right side of the body 1, the rubber ring 712 is fixedly installed at the junction of the wire box 709 and the body 1, the scraper 706 is slidably installed on the right side of the body 1, one end of the thin rod 707 is rotatably installed on the end of the scraper 706 away from the roller 703, and the moving ring 708 is rotatably installed on the other end of the thin rod 707, which reduces the need for manual cleaning of the wire box 709, especially in processing scenarios such as this containing viscous chemicals or easily agglomerated substances, extending the continuous operation time of the equipment, and avoiding the accumulation of residual lines at the sealing interface, which may cause chemical leakage or internal corrosion of the equipment.

[0028] The gear 701 is meshed with the semicircular rod 702, the width of the ring 711 is greater than the spacing between the tooth blocks, the ring 711 is in contact with the rubber ring 712, and the ring 711 is in contact with the movable ring 708. When the scraper 706 moves, it will move toward the middle. When the next primary screening plate 608 is inserted, the ring 711 will be pulled out of the wire box 709. When the ring 711 is pulled out of the wire box 709, the scraper 706 will scrape out the lines above the ring 711.

[0029] When this embodiment works: when the flat ring rod 503 moves up and down, it will contact the push rod 601. When the flat ring rod 503 contacts the push rod 601, the push rod 601 will move. When the push rod 601 moves, it will drive the pressure rod 602 to move. When the pressure rod 602 moves, the sponge inside the sponge frame 603 will be squeezed, so that the liquid in the sponge will be squeezed out. When the primary screening plate 608 is inserted into the body 1, the ladder block 605 will be squeezed. When the ladder block 605 is squeezed, pressure is generated on the U rod 604, so that the U rod 604 and the ladder block 605 move outward at the same time until the primary screening plate 608 is fully inserted into the body 1. When the primary screening plate 608 is fully inserted into the body 1, the U rod 604 will bring the ladder block 605 closer to the middle. Thereby, the primary screening plate 608 is limited, and when the U rod 604 moves, the primary screening plate 608 will be driven to move. When the primary screening plate 608 moves, the double rotating rod 607 will be driven to move. When the double rotating rod 607 moves, the primary screening plate 608 will be limited for a second time. When the primary screening plate 608 needs to be taken out, only the three rotating rods 606 need to be pulled downward, which will cause the U rod 604 to move outward and the double rotating rod 607 to move upward, thereby releasing the limit on the primary screening plate 608. When the staff inserts the primary screening plate 608 into the body 1, the gap of the body 1 is too small. In order to avoid the staff from being able to accurately insert the primary screening plate 608, the ladder block 605 can effectively provide guidance for the staff to insert the primary screening plate 608.

[0030] When the sieve plate 608 is initially pulled out, it drives the gear 701 to rotate. When the gear 701 rotates, it collects the lines in the liquid. When the gear 701 rotates, it drives the semicircular rod 702 to move. When the semicircular rod 702 moves, the semicircular block inside the roller 703 is compressed. When the semicircular block is compressed, the tooth block above the roller 703 retracts. At the same time, when the gear 701 rotates, it drives the reciprocating screw 705 to rotate. When the reciprocating screw 705 rotates, it drives the moving block 704 to move. When the moving block 704 moves, it drives the connecting rod 710 to move. When the connecting rod 710 moves, it drives the ring 711 to move. When the ring 711 moves, it pushes the lines above the roller 703. At the same time, the width of the circular ring 711 is greater than the distance between each two tooth blocks, so when the circular ring 711 moves to the position of the rubber ring 712, it will press the last block to prevent the tooth block from protruding. When the circular ring 711 moves, it will push the rubber ring 712. When the circular ring 711 pushes the rubber ring 712 into the wire box 709, the circular ring 711 will first squeeze the moving ring 708. When the moving ring 708 is squeezed, it will drive the thin rod 707 to move. When the thin rod 707 moves, it will drive the scraper 706 to move. When the scraper 706 moves, it will move closer to the middle. When the next primary screening plate 608 is inserted, the circular ring 711 will exit the wire box 709. When the circular ring 711 exits the wire box 709, the scraper 706 will scrape out the lines above the circular ring 711.
