Description

Technical Field

[0001] The invention belongs to the technical field of wastewater purification and treatment, in particular to a textile wastewater purification device. Background Art

[0002] Textile wastewater refers to wastewater discharged from cleaning, processing, equipment cleaning and other processes in all links of the textile industry chain, from fiber raw material pretreatment, spinning, weaving, dyeing, printing to finishing. It covers all liquid waste generated during the processing of natural fibers (cotton, linen, silk, wool) and chemical fibers (polyester, nylon, etc.).

[0003] In the current existing technology, when pre-treating and filtering wastewater generated in textile processing, a fence is usually used to filter and intercept solid waste (such as textile fibers, cotton threads, etc.) in the wastewater. When the direct current fence filter device is in use, the rake teeth are driven by a chain to rotate. When the rake teeth come into contact with the fence, the solid waste intercepted by the fence is collected and transported, so that the fence can continuously intercept the solid waste in the textile wastewater. However, since the rake teeth will continuously come into direct contact with the fence, when collecting the solid waste intercepted by the fence, after the rake teeth are used for a long time, waste such as textile fibers will stick to the surface of the rake teeth. When a large amount of waste accumulates on the surface of the rake teeth, it will directly affect the insertion of the rake teeth into the fence, making it impossible to effectively collect and transport the solid waste intercepted by the fence, causing a large amount of waste to accumulate in the gaps of the fence, affecting the effect of the fence in preventing continuous filtration of wastewater, and reducing the effect of textile wastewater purification.

[0019] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0020] like Figures 1 to 6 As shown, a textile wastewater purification device according to an embodiment of the present invention includes two mounting posts 1, a mounting plate 8 is fixedly connected above the two mounting posts 1, a fence 5 is provided on opposite sides of the mounting posts 1, a plurality of rake teeth 304 are provided on one side of the fence 5, and a cleaning mechanism 7 for cleaning solid waste collected inside the rake teeth 304 is provided below the mounting plate 8; The cleaning mechanism 7 includes a swingable swing frame 701, and a telescopic scraper 704 is slidably connected inside the swing frame 701. One side of the telescopic scraper 704 is slidably contacted with a fixed rod 702, and one end of the fixed rod 702 is fixedly connected to the mounting plate 8.

[0021] The present invention takes into account that when a DC type fence is used to pre-treat solid waste in textile wastewater, it is first necessary to install the DC type fence to the drain outlet of the wastewater so that the fence 5 is in direct contact with the wastewater. When the fence 5 starts to pre-treat and filter the wastewater, the solid waste intercepted by the fence 5 can be lifted and collected by the reciprocating motion of the plurality of rake teeth 304 adapted to the fence 5. Although the waste collected inside the rake teeth 304 will be discharged after rising to the top of the installation column 1, some waste that cannot fall off by relying on the gravity of the waste will still remain on the surface of the rake teeth 304. When the rake teeth 304 are used for a long time, the solid waste will continue to accumulate and adhere to the surface of the rake teeth 304, eventually making it impossible for the rake teeth 304 to collect and transport the solid waste intercepted by the fence 5, thereby causing a large amount of waste to accumulate on the surface of the fence 5, and ultimately making it impossible to pre-treat and purify the textile wastewater. Therefore, first, the solid waste intercepted on the surface of the fence 5 is lifted and transported by reciprocating lifting of multiple groups of rake teeth 304, so that the solid waste can be continuously cleaned from the surface of the fence 5 by multiple groups of rake teeth 304, which can effectively improve the effect of the fence 5 on textile wastewater treatment, and when the rake teeth 304 move upward to the bottom position of the swing frame 701, the rake teeth 304 will continue to move, thereby generating an extrusion force on the bottom of the swing frame 701, causing the swing frame 701 to swing, and the bottom will continue to contact the inside of the rake teeth 304. It should be noted that since the bottom surface of the inner part of the rake teeth 304 is arranged in an arc shape and tilted, the bottom of the swing frame 701 can fully contact the inside of the rake teeth 304 at this time, thereby hanging out the solid waste collected by the rake teeth 304, thereby realizing the discharge of waste; Specifically, when the swing frame 701 is swung by the upward movement of the rake teeth 304, the swing trajectory of the swing frame 701 is fixed. At this time, the swing frame 701 will move toward one end of the fixed rod 702, so that the fixed rod 702 is inserted into the interior of the swing frame 701. Since the bottom surface of the fixed rod 702 is inclined, the fixed rod 702 will contact the top surface of the telescopic scraper 704 inside the swing frame 701, thereby squeezing the telescopic scraper 704. When the telescopic scraper 704 is continuously squeezed by the fixed rod 702, the telescopic scraper 704 will extend from the interior of the swing frame 701. The scraper 704 is inserted into the gap of the rake teeth 304, thereby scraping the waste adhered to the gap position of the rake teeth 304, so that the position where the rake teeth 304 and the fence 5 are adapted is in a clean state, which facilitates the rake teeth 304 to continue to rotate and cooperate with the fence 5, so that the solid waste intercepted by the fence 5 can be collected and transported. It should be noted that since the rake teeth 304 are not matched with the fence 5 as a whole, only the position inserted into the interior of the fence 5 will be scraped by the telescopic scraper 704, which can prevent the telescopic scraper 704 from being inserted into the drainage hole opened inside the rake teeth 304, and can improve the smoothness of the movement of the rake teeth 304; Furthermore, when the rake teeth 304 are no longer in contact with the bottom of the swing frame 701, that is, the telescopic scraper 704 is removed from the gap of the rake teeth 304, the rake teeth 304 no longer apply thrust to the swing frame 701 until the rake teeth 304 lose contact with the swing frame 701. At this time, the swing frame 701 will reset, and the telescopic scraper 704 will be reset inside the telescopic scraper 704 under the tension of the reset spring at the same time as the swing frame 701 resets, until the next time the waste in the gap position of the rake teeth 304 is scraped and cleaned. It should be noted that, since the width of the gaps between the fences 5 is greater than the width of the rake teeth 304 inserted into the interior of the fence 5, that is, in order to prevent the rake teeth 304 from being unable to effectively insert into the gaps of the fence 5, the gap width of the telescopic scraper 704 is also set to be the same as the width of the gaps of the fence 5, so that the gaps of the rake teeth 304 can be cleaned in advance and adapted to the gaps of the fence 5, thereby preventing the rake teeth 304 from being unable to effectively insert into the interior of the fence 5, and collecting and transporting the fence 5 and the waste intercepted therein; Furthermore, since the telescopic scraper 704 is driven by the swing of the swing frame 701, when the telescopic scraper 704 is inserted into the gap position of the rake teeth 304, the telescopic scraper 704 will be slowly removed from the gap of the rake teeth 304 in an arc-shaped motion trajectory, which is very different from the vertical removal of the rake teeth 304 from the gap inside the fence 5. The telescopic scraper 704 can fully scrape and clean the waste in the gap position of the rake teeth 304, thereby improving the subsequent cleaning effect of the rake teeth 304 on the waste intercepted by the fence 5, and improving the quality of textile wastewater pretreatment and purification.

[0022] like Figures 1 to 3 As shown, a motion mechanism 3 for driving the rake teeth 304 to move is also configured under the mounting plate 8. The motion mechanism 3 includes a motor 301 fixedly arranged on one side of the mounting column 1. The output end of the motor 301 is fixedly connected to a transmission shaft 302. Two sprockets are fixedly connected to the surface of the transmission shaft 302. The transmission shaft 302 is engaged with a chain 303 through the sprockets, and the rake teeth 304 are detachably mounted on one side of the chain 303.

[0023] During operation, when the plurality of rake teeth 304 are running to lift and transport the solid waste intercepted by the fence 5, the motor 301 is first started to drive the transmission shaft 302 to rotate. The rotation of the transmission shaft 302 drives the chain 303 to rotate through the plurality of sprockets. The rotation of the chain 303 drives the plurality of rake teeth 304 to lift and transport the solid waste intercepted by the fence 5. It should be noted that by providing drainage holes at the position where the rake teeth 304 are not inserted into the gap of the fence 5, the wastewater contained in the solid waste can be filtered after being lifted from the wastewater, which can improve the cleaning effect of the subsequent fixed rod 702 and the telescopic scraper 704 on the rake teeth 304, and can prevent the waste from being broken due to the entanglement of wastewater and textile fibers after the contact and friction between the fixed rod 702 and the telescopic scraper 704 and the rake teeth 304, thereby effectively improving the effect of solid waste collection; Specifically, by installing the rake teeth 304 on the opposite side of the two chains 303, when the rake teeth 304 are driven by the chains 303 to lift and clean solid waste, the engagement of the chains 303 with the multiple sprockets can effectively improve the stability of the rake teeth 304 during operation. It should be noted that when the chains 303 drive the rake teeth 304 to move to a position away from the side of the fence 5, the interior of the rake teeth 304 will become downward, so that the small waste scraped off by the fixed rod 702 and the telescopic scraper 704 can fall naturally by gravity, and the wastewater can flow out from the inside of the rake teeth 304, which can further improve the cleanliness of the rake teeth 304, facilitate the subsequent cleaning of the waste intercepted by the fence 5, and improve the effect of the fence 5 on the pretreatment of waste in the wastewater.

[0024] like Figures 7 to 10 As shown, both ends of the rake teeth 304 are configured with a gain mechanism 6 for improving the stability of the rake teeth 304 during operation. The gain mechanism 6 includes a connecting tube 601, one side of the connecting tube 601 is fixedly connected to the mounting tube 602, the interior of the connecting tube 601 is fixedly connected to a sliding base 606, one side of the sliding base 606 is fixedly connected to one end of a torsion spring 607, the other end of the torsion spring 607 is fixedly connected to a fixing plate 608, and the fixing plate 608 is slidably engaged on the surface of the rake teeth 304.

[0025] During operation, when the rake teeth 304 rise and contact the bottom of the swing frame 701, the chain 303 will drive the rake teeth 304 to continue to move, applying a thrust to the swing frame 701, so that the swing frame 701 can swing along a certain trajectory. At this time, the swing frame 701 will also apply a thrust to the rake teeth 304 in the opposite direction, so that the rake teeth 304 also rotate and tilt to a certain extent, so that the waste collected by the rake teeth 304 can be better discharged, avoiding the waste from accumulating inside the rake teeth 304 and affecting the rake teeth 304. Normal operation, it should be noted that, when the swing frame 701 applies a reverse thrust to the rake teeth 304, the rake teeth 304 rotate a certain angle to drive the fixed plate 608 to rotate, and the rotation of the fixed plate 608 can drive the torsion spring 607 to rotate. At this time, the torsion spring 607 will store force. When the rake teeth 304 are no longer subjected to the reverse thrust of the swing frame 701, the torsion spring 607 will release the elastic force to reset the rake teeth 304, which can facilitate the subsequent rake teeth 304 to continue to collect and clean the waste intercepted by the fence 5; It should be noted that when the torsion spring 607 is no longer subjected to the torsional force of the rake teeth 304, the torsion spring 607 will drive the rake teeth 304 to reset, and since the rake teeth 304 instantly lose contact with the bottom of the swing frame 701, the torsion spring 607 will quickly drive the rake teeth 304 to reset, while causing the rake teeth 304 to generate a certain vibration, and at this time the rake teeth 304 are in a tilted state following the rotation and flipping of the chain 303. At this time, the vibration force can not only shake off the waste, causing the waste to fall naturally under the action of gravity, but also improve the effect of wastewater falling.

[0026] like Figures 7 to 10 As shown, a sliding cylinder 603 is slidably extended on one side of the mounting cylinder 602, a plurality of wedge plates 610 are fixedly connected to the interior of the mounting cylinder 602, a plurality of sliding posts 609 are in sliding contact with the inner wall of the wedge plates 610, the sliding posts 609 are fixedly connected to the rake teeth 304, and the fixed plate 608 is slidably connected to the mounting cylinder 602.

[0027] When the teeth 304 are in operation, the torsion spring 607 on one side of the fixed plate 608 is driven to store force, and the teeth 304 are also driven to rotate by the plurality of slide posts 609. When the slide posts 609 rotate, one end of the slide posts 609 will slide in contact with the inner wall of the wedge plate 610. Since the inner surface of the wedge plate 610 is wedge-shaped, the slide posts 609 will rotate with the teeth 304, and one end of the slide posts 609 will continuously rub against the wedge plate 610, so that the slide posts 609 are in a stable state after friction and extrusion, thereby improving the stability of the teeth 304 at one end of the slide posts 609 after rotation, and preventing the torsion spring 607 from storing force for too long and causing damage. It can also prevent the torsion spring 607 from causing damage to the torsion spring 607 when the teeth 304 are quickly reset after being out of contact with the swing frame 701, thereby improving the stability, effectively improving the stability of the teeth 304 during the discharging process, and improving the cleanliness of the teeth 304.

[0028] like Figures 1 to 2 as well as Figure 11 As shown, two partitions are provided inside the mounting column 1, and a plurality of matching plates 9 are fixedly connected between the two partitions. Two push rods 10 are fixedly connected to both sides of the rake teeth 304, and the matching plates 9 are staggered with the push rods 10 in spatial position.

[0029] During operation, after the rake teeth 304 follow the chain 303 to flip, the interior of the rake teeth 304 is in a downward state. When the chain 303 drives the rake teeth 304 to move downward, the push rods 10 on both sides of the rake teeth 304 will contact the matching plate 9. At this time, due to the gain mechanism 6 set on both sides of the rake teeth 304, the rake teeth 304 can also be flipped, and due to the different inclination angles of the top matching plate 9 and the multiple matching plates 9 below, when the push rods 10 on both sides of the rake teeth 304 contact the top matching plate 9, the rake teeth 304 will rotate. After the rake teeth 304 continue to move downward, the push rods 10 on both sides of the rake teeth 304 will continuously contact the multiple matching plates 9 below, so that the rake teeth 304 move downward in a state of continuous reciprocating swinging, which is equivalent to the rake teeth 304 continuously knocking on the matching plates 9 through the push rods 10 on both sides, so that the rake teeth 304 vibrate while moving downward and reciprocatingly swinging, so that the waste adhered to the inside of the rake teeth 304 can be better dropped, so that the rake teeth 304 can maintain a certain degree of cleanliness before entering the water, which can effectively improve the self-cleaning effect of the rake teeth 304; It should be noted that, since the topmost mating plate 9 and the multiple mating plates 9 below are arranged at a 60° angle in space, when the rake teeth 304 contact the topmost mating plate 9 through the push rods 10 on both sides, the rake teeth 304 will swing to the maximum angle. When the push rods 10 on both sides of the rake teeth 304 are out of contact with the mating plate 9, continuing to move downward will cause the push rods 10 on both sides of the rake teeth 304 to contact the second mating plate 9 with the maximum swing amplitude, thereby generating the maximum vibration force, which can first vibrate and disperse the waste adhered to the inside of the rake teeth 304, and then after contacting the multiple mating plates 9, the dispersed waste can be shaken off, so that the waste adhered to the inside of the rake teeth 304 can be fully fallen off, thereby further improving the self-cleaning effect of the rake teeth 304. Furthermore, when the rake teeth 304 are in continuous contact with the matching plate 9 through the push rods 10, the rake teeth 304 will flip counterclockwise through the contact with the push rods 10 on both sides. At the same time, when the rake teeth 304 are constantly swinging back and forth, the detached small waste will be thrown to the position of the fence 5 and flow out from the gap of the fence 5, which is convenient for subsequent processing and will not cause the waste adhered to the inside of the rake teeth 304 to fall directly below it. After the rake teeth 304 enter the water, they will contact the inside of the rake teeth 304 again, be intercepted and lifted by the rake teeth 304 for transportation, which can prevent the detached small waste from contacting the rake teeth 304 again and can improve the overall cleanliness of the rake teeth 304 before entering the water.

[0030] like Figures 7 to 10 As shown, one side of the sliding cylinder 603 is fixedly connected to multiple insertion rods 604, one end of the insertion rod 604 is slidably inserted with a fixing sleeve 605, the fixing sleeve 605 is fixedly connected to the side of the rake tooth 304, and the sliding cylinder 603 is slidably connected to one end of the rake tooth 304.

[0031] During operation, in order to prevent the rake teeth 304 from being positionally deviated when resetting after continuous contact with the multiple matching plates 9 through the push rods 10 on both sides, the subsequent rake teeth 304 cannot be accurately inserted into the gaps of the fence 5. At this time, when the rake teeth 304 contact the multiple matching plates 9 through the push rods 10, the rake teeth 304 will also drive the torsion spring 607 to store force multiple times, so that the rake teeth 304 can swing counterclockwise for multiple times. Therefore, the rake teeth 304 are driven by the fixing plate 608 to rotate counterclockwise. When the dynamic torsion spring 607 rotates and accumulates force, the fixed plate 608 also slides and displaces, so that the fixed plate 608 pushes the sliding cylinder 603 to slide inside the mounting cylinder 602 toward the side close to the rake teeth 304. When the sliding cylinder 603 slides, it drives multiple insertion rods 604 to insert into the interior of the fixed sleeve 605, so that the sliding cylinder 603 and the rake teeth 304 form a whole, so that the torsion spring 607 can stably drive the rake teeth 304 to reciprocate and improve the stability of the rake teeth 304 when self-cleaning; It should be noted that, since the insertion rod 604 is inserted into the interior of the fixed sleeve 605, and the fixed sleeve 605 is fixedly connected to the rake teeth 304, the stability of the sliding cylinder 603 after being inserted into the interior of the fixed sleeve 605 can be improved, and since the multiple sliding columns 609 on the surface of the rake teeth 304 will also be in sliding friction contact with the wedge plate 610, the stability of the rake teeth 304 during reciprocating swinging and bouncing can be further improved, and since the distance between the multiple matching plates 9 is relatively close, when the insertion rod 604 is inserted into the interior of the fixed sleeve 605, even if the rake teeth 304 are constantly swinging back and forth, the insertion rod 604 will not fall off from the interior of the fixed sleeve 605, which can effectively improve the stability of the rake teeth 304 during swinging.

[0032] like Figure 11 As shown, a water spray mechanism 2 for spraying high-pressure wastewater is provided in front of the mounting column 1. The water spray mechanism 2 includes a water spray pump 201 fixedly connected to one side of the mounting column 1. A water inlet pipe 202 is provided below the water spray pump 201. The water inlet pipe 202 is located in the wastewater, and a filter ball is provided at the bottom of the water inlet pipe 202. A water spray pipe 203 is provided in the middle of the water spray pump 201, and the water spray pipe 203 is provided in an inclined direction.

[0033] During operation, when the rake teeth 304 move downward and continuously contact the matching plate 9 through the push rod 10, the water spray pump 201 is started to pump the wastewater into the interior of the water spray pump 201 through the filter ball and then transmit it to the position of the water spray pipe 203. At this time, the wastewater will be sprayed into the interior of the rake teeth 304 that are swinging back and forth at high pressure, which can flush the vibrated discrete waste and further improve the cleaning effect of the interior of the rake teeth 304. It should be noted that since the rake teeth 304 are constantly swinging back and forth at this time, when the high-pressure wastewater is sprayed from the inside of the water spray pipe 203 to the inside of the rake teeth 304, the rake teeth 304 will swing the discrete waste and wastewater together to the position of the fence 5, and then flow out from the gap of the fence 5, which is convenient for the subsequent secondary filtration of small-volume waste, and will not cause small-volume waste to adhere to the gap position of the fence 5, which can improve the effect of the fence 5 in pre-treating textile wastewater.

[0034] like Figures 4 to 6 As shown, the bottom of the swing frame 701 is located at the sliding position of the telescopic scraper 704 and a plurality of baffles 706 are provided by rotating the pin shaft. The baffles 706 are separated from the inside of the rake teeth 304, and the bottom of the swing frame 701 is arc-shaped.

[0035] When the scraper 704 is in operation, it is pushed by the two fixed rods 702 and slides out from the inside of the swing frame 701, so that the waste in the gap position of the rake teeth 304 can be scraped, thereby improving the cleanliness of the rake teeth 304. However, since the scraper 704 will also move in a certain circular motion trajectory when sliding inside the swing frame 701, some small waste will inevitably adhere to the surface of the scraper 704. When the scraper 704 slides back to its original position inside the swing frame 701, the surface of the scraper 704 will contact the baffle 706, and the baffle 706 will scrape the waste adhered to the surface of the scraper 704, so that the surface of the scraper 704 is also in a clean state, which can improve the effect of the subsequent scraper 704 continuing to scrape and clean the gaps of multiple rake teeth 304, and can further improve the cleaning effect of the rake teeth 304, making it convenient to clean the waste intercepted by the fence 5 in the future. When the scraper 704 slides out, the curved bottom surface of the swing frame 701 contacts the position where the rake teeth 304 are inserted into the fence 5, and the scraper 704 is located at the gap of the rake teeth 304 at this time.

[0036] like Figures 4 and 5 As shown, a rotating rod 703 is fixedly connected to the top of the swing frame 701, and the rotating rod 703 is rotatably connected to the mounting plate 8. In addition, multiple groups of tension springs 705 are provided at the angle position between the swing frame 701 and the mounting plate 8, and the tension springs 705 are arranged in an arc shape.

[0037] When the cam 701 is in contact with the tooth 304, the cam 701 is in contact with the tooth 304, and the cam 701 is in contact with the tooth 304. When the cam 701 is in contact with the tooth 304, the cam 701 is in contact with the tooth 304, and ...

[0038] like Figures 1 to 3 As shown, a collection box 4 for collecting solid waste discharged by the rake teeth 304 is fixedly connected to one side of the mounting column 1, a protective shell is fixedly connected to the surface of the transmission shaft 302, and a waterproof gasket is provided between the protective shell and the motor 301, and the rake teeth 304 are made of high-strength and wear-resistant material.

[0039] During operation, when the swing frame 701 is pushed to swing by the movement of the rake teeth 304, and the rake teeth 304 are also swung under the reverse thrust of the swing frame 701, the solid waste inside the rake teeth 304 will fall from the inside of the rake teeth 304 to the inside of the collection box 4 for collection, and the smaller waste adhering to the inside of the rake teeth 304 will be subsequently processed and flow out from the gaps in the fence 5 for secondary purification treatment, which can effectively improve the effect of pretreatment of textile wastewater, thereby improving the effect of preventing wastewater purification.
