Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of wastewater purification treatment, and particularly relates to a textile wastewater purification device. BACKGROUND

[0002] Textile wastewater refers to wastewater discharged in the process of cleaning, processing, equipment cleaning and the like in each link of the whole textile industry chain from fiber raw material pretreatment, spinning, weaving, dyeing, printing to finishing, which covers all liquid waste generated in the processing of natural fibers (cotton, hemp, silk and wool) and chemical fibers (polyester and nylon).

[0003] At present, in the prior art, when the wastewater generated in textile processing is pretreated and filtered, a fence is usually used to filter and intercept solid waste (for example, textile fibers and cotton silk) in the wastewater. When a straight-flow fence filtering device is used, a chain is used to drive a rake to rotate, and when the rake contacts the fence, the solid waste intercepted by the fence can be collected and transported, so that the fence can continuously intercept the solid waste in the textile wastewater.

[0004] However, since the rake directly contacts the fence continuously, when the solid waste intercepted by the fence is collected, the textile fibers and the like will stick to the surface of the rake after long-time use. When a large amount of waste accumulates on the surface of the rake, the rake cannot be inserted into the fence, and the solid waste intercepted by the fence cannot be effectively collected and transported, so that a large amount of waste accumulates in the gap of the fence, which affects the continuous filtering effect of the fence on the wastewater and reduces the purification effect of the textile wastewater.

DETAILED DESCRIPTION

[0033] In order to make the technical means, creative features, purposes and effects realized by the application easy to understand, the application is further described below in combination with specific embodiments.

[0034] As shown in Figures 1 to 6 , the textile wastewater purification device provided by the embodiment of the application comprises two mounting columns 1, the upper portions of the two mounting columns 1 are fixedly connected with a mounting plate 8, the opposite side of the mounting column 1 is provided with a fence 5, one side of the fence 5 is provided with a plurality of harrow teeth 304, and the lower portion of the mounting plate 8 is configured with a cleaning mechanism 7 for cleaning the solid waste collected in the harrow teeth 304.

[0035] The cleaning mechanism 7 comprises a swingable swing frame 701, the inside of the swing frame 701 is slidably connected with a telescopic scraper 704, one side of the telescopic scraper 704 is slidably connected with a fixed rod 702, and one end of the fixed rod 702 is fixedly connected with the mounting plate 8.

[0036] The present application considers that when the straight-flow fence is used for pretreatment of solid waste in textile wastewater, the straight-flow fence needs to be installed at the wastewater outlet first, so that the fence 5 is in direct contact with the wastewater. When the fence 5 starts to pretreat and filter the wastewater, the reciprocating movement of the plurality of rake teeth 304 adapted to the fence 5 can lift and collect the solid waste intercepted by the fence 5. Although the collected waste inside the rake teeth 304 is discharged after rising to the top of the mounting column 1, some waste that cannot rely on the gravity of the waste to fall off will still remain on the surface of the rake teeth 304. During the long-term use of the rake teeth 304, the solid waste will continuously accumulate and adhere to the surface of the rake teeth 304, eventually causing the rake teeth 304 to be unable to collect and transport the solid waste intercepted by the fence 5, which will also cause a large amount of waste to accumulate on the surface of the fence 5, eventually causing the textile wastewater to be unable to be pretreated and purified.

[0037] Therefore, the solid waste intercepted on the surface of the fence 5 is first lifted and transported by the reciprocating lifting of the plurality of rake teeth 304, so that the solid waste can be continuously cleaned from the surface of the fence 5 by the plurality of rake teeth 304, which can effectively improve the effect of the fence 5 on the treatment of textile wastewater. 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 a pressing force on the bottom of the swing frame 701, causing the swing frame 701 to swing and the bottom to continuously contact the inside of the rake teeth 304. It should be noted that since the inside bottom surface of the rake teeth 304 is arc-shaped and inclined, the bottom of the swing frame 701 can fully contact the inside of the rake teeth 304, thereby hanging out the solid waste collected by the rake teeth 304 and discharging the waste.

[0038] Specifically, when the swing frame 701 is swung by the upward movement of the tines 304, the trajectory of the swing frame 701 is fixed, and the swing frame 701 will move towards 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 extruding the telescopic scraper 704. When the telescopic scraper 704 is continuously extruded by the fixed rod 702, the telescopic scraper 704 will extend from the interior of the swing frame 701, thereby being inserted into the gap of the tines 304, thereby scraping the waste adhered to the gap position of the tines 304, so that the position of the tines 304 adapted to the fence 5 is in a clean state, facilitating the continuous rotation of the tines 304 and the cooperation with the fence 5, thereby being able to collect and transport the solid waste intercepted by the fence 5. It should be noted that since the tines 304 are not entirely cooperated with the fence 5, only the position inserted into the interior of the fence 5 will be scraped by the telescopic scraper 704, which can avoid the telescopic scraper 704 being inserted into the drainage hole formed in the interior of the tines 304, thereby improving the smoothness of the movement of the tines 304.

[0039] Further, when the tines 304 are no longer in contact with the bottom of the swing frame 701, i.e., after the telescopic scraper 704 is removed from the gap of the tines 304, the tines 304 no longer apply a pushing force to the swing frame 701 until the tines 304 lose contact with the swing frame 701. At this time, the swing frame 701 will be reset, and the telescopic scraper 704 will be reset inside the swing frame 701 under the tension of the reset spring, until the next time the waste in the gap of the tines 304 is scraped and cleaned. It should be noted that since the gap width of the fence 5 is greater than the width of the tines 304 inserted into the interior of the fence 5, in order to avoid the tines 304 being unable to effectively insert into the gap position of the fence 5, the gap width of the telescopic scraper 704 is also set to be the same as the width of the gap of the fence 5, so that the gap of the tines 304 can be cleaned in advance, so that it can be adapted to the gap of the fence 5, thereby avoiding the tines 304 being unable to effectively insert into the interior of the fence 5, and collecting and transporting the waste intercepted by the fence 5.

[0040] Further, 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 tines 304, the telescopic scraper 704 will move along an arc trajectory and slowly remove from the gap of the tines 304, which is quite different from the vertical removal of the tines 304 from the gap in the interior of the fence 5, so that the telescopic scraper 704 can fully scrape and clean the waste in the gap position of the tines 304, thereby improving the cleaning effect of the waste intercepted by the fence 5 by the tines 304, and improving the quality of the textile wastewater pretreatment and purification.

[0041] As Figures 1 to 3 shown, the lower part of the mounting plate 8 is also configured with a movement mechanism 3 for driving the movement of the rake teeth 304, the movement mechanism 3 includes an electric motor 301 fixedly arranged on one side of the mounting column 1, the output end of the electric motor 301 is fixedly connected with a transmission shaft 302, the surface of the transmission shaft 302 is fixedly connected with two chain wheels, the transmission shaft 302 is driven by the chain wheels to engage the chain 303, and the rake teeth 304 are detachably installed on one side of the chain 303.

[0042] When working, when the plurality of rake teeth 304 operates to lift and transport the solid waste intercepted by the fence 5, first start the electric motor 301 to drive the transmission shaft 302 to rotate, the transmission shaft 302 rotates to drive the chain 303 to rotate through the plurality of chain wheels, and the chain 303 rotates to drive the plurality of rake teeth 304 to lift and transport the solid waste intercepted by the fence 5. It should be noted that by opening a drainage hole at the position where the rake teeth 304 are not inserted into the gap of the fence 5, the solid waste can be lifted from the wastewater, the wastewater contained in the solid waste can be filtered, the cleaning effect of the fixed rod 702 and the telescopic scraper 704 on the rake teeth 304 can be improved, and after the fixed rod 702 and the telescopic scraper 704 come into contact with the rake teeth 304, the solid waste can be prevented from being broken due to the rubbing of the wastewater and the textile fibers, and the effect of collecting the solid waste can be effectively improved.

[0043] Specifically, by installing the rake teeth 304 on the opposite sides of the two chains 303, when the rake teeth 304 are driven by the chain 303 to lift and clean the solid waste, the engagement of the chain 303 with the plurality of chain wheels can effectively improve the stability of the rake teeth 304 during operation. It should be noted that when the chain 303 drives the rake teeth 304 to move away from the fence 5, the inside 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 naturally fall off by gravity, and the wastewater can flow out of 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 the waste in the wastewater.

[0044] As Figures 7 to 10 shown, the two 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 cylinder 601, one side of the connecting cylinder 601 is fixedly connected with a mounting cylinder 602, the inside of the connecting cylinder 601 is fixedly connected with a sliding base 606, one side of the sliding base 606 is fixedly connected with one end of a torsional spring 607, the other end of the torsional spring 607 is fixedly connected with a fixed plate 608, and the fixed plate 608 is slidingly connected on the surface of the rake teeth 304.

[0045] When the tines 304 rise and contact the bottom of the swing frame 701, the chain 303 drives the tines 304 to continue to move, a pushing force is applied to the swing frame 701, so that the swing frame 701 can swing along a certain trajectory, at this time the swing frame 701 also applies a reverse pushing force to the tines 304, so that the tines 304 also rotate and tilt, so that the waste collected by the tines 304 can be better discharged, avoiding the accumulation of waste in the tines 304, affecting the normal operation of the tines 304. It should be noted that when the swing frame 701 applies a reverse pushing force to the tines 304, the tines 304 rotate by a certain angle to drive the fixed plate 608 to rotate, and the rotation of the fixed plate 608 drives the torsional spring 607 to rotate, at this time the torsional spring 607 stores energy, when the tines 304 no longer receive the reverse thrust of the swing frame 701, the torsional spring 607 releases the elastic force to reset the tines 304, which can facilitate the subsequent tines 304 to continue to collect and clean the waste intercepted by the fence 5.

[0046] It should be noted that when the torsional spring 607 no longer receives the torsional force of the tines 304, the torsional spring 607 drives the tines 304 to reset, and because the tines 304 lose contact with the bottom of the swing frame 701 instantaneously, the torsional spring 607 quickly drives the tines 304 to reset while making the tines 304 vibrate, and at this time the tines 304 follow the rotation of the chain 303 and are in an inclined state. At this time, the vibration force can not only vibrate the waste to make it fall naturally under the action of gravity, but also improve the falling effect of the waste.

[0047] As shown in Figures 7 to 10 The installation cylinder 602 has a sliding cylinder 603 on one side, the inside of the installation cylinder 602 is fixedly connected with a plurality of wedge plates 610, the inner wall of the wedge plate 610 is in sliding contact with a plurality of slide columns 609, the slide column 609 is fixedly connected with the tines 304, and the fixed plate 608 is slidingly connected with the installation cylinder 602.

[0048] When the rake tooth 304 is flipped and swings to drive the torsion spring 607 on one side of the fixed plate 608 to store energy, the rake tooth 304 also drives the plurality of slide columns 609 to rotate at this time. When the slide column 609 rotates, one end thereof is in sliding contact with the inner wall of the wedge plate 610. Since the inner surface of the wedge plate 610 is wedge-shaped, after the slide column 609 rotates with the rake tooth 304, one end thereof is constantly in frictional contact with the wedge plate 610, so that the slide column 609 is in a stable state after being frictionally extruded, thereby improving the stability of the rake tooth 304 after the rotation of one end thereof, avoiding damage caused by the overlong storage of the torsion spring 607, avoiding damage to the torsion spring 607 caused by the rapid resetting of the rake tooth 304 after the rake tooth 304 is out of contact with the swing frame 701, improving stability, effectively improving the stability of the rake tooth 304 during discharging, and improving the cleanliness of the rake tooth 304.

[0049] As shown in Figures 1 to 2 and Figure 11 The inside of the mounting column 1 is provided with two partitions, and a plurality of matching plates 9 are fixedly connected between the two partitions. The two sides of the rake tooth 304 are fixedly connected with two push rods 10, and the matching plates 9 are staggered with the push rods 10 in spatial position.

[0050] When the rake tooth 304 is flipped with the chain 303, the inside of the rake tooth 304 is in a downward state at this time. When the chain 303 drives the rake tooth 304 to move downward, the push rods 10 on both sides of the rake tooth 304 will be in contact with the matching plates 9 at this time. Since the gain mechanism 6 is arranged on both sides of the rake tooth 304, the rake tooth 304 can also be flipped. Since the inclination angles of the uppermost matching plate 9 and the plurality of lower matching plates 9 are different, when the push rods 10 on both sides of the rake tooth 304 are in contact with the uppermost matching plate 9, the rake tooth 304 will rotate. When the rake tooth 304 continues to move downward, the push rods 10 on both sides of the rake tooth 304 will constantly contact the plurality of lower matching plates 9, so that the rake tooth 304 moves downward in a reciprocating swinging state. In other words, the rake tooth 304 constantly knocks the matching plates 9 through the push rods 10 on both sides, so that the rake tooth 304 vibrates in a downward moving and reciprocating swinging state, so that the waste adhered to the inside of the rake tooth 304 falls better, so that the rake tooth 304 can maintain a certain cleanliness before entering the water, and the self-cleaning effect of the rake tooth 304 is effectively improved.

[0051] It needs to be explained that, since the uppermost one of the cooperating plates 9 is arranged at a spatial position of 60° angle with the lower ones, when the tine 304 is in contact with the uppermost cooperating plate 9 through the push rods 10 on both sides, the tine 304 will swing to the maximum angle, and when the push rods 10 on both sides of the tine 304 are out of contact with the cooperating plate 9, the tine 304 will be in contact with the second cooperating plate 9 when it continues to move downward, thus generating the maximum vibration force, which can first vibrate and disperse the waste adhered inside the tine 304, and then vibrate and drop the dispersed waste after being in contact with the cooperating plates 9, so that the waste adhered inside the tine 304 can be fully dropped, thus further improving the self-cleaning effect of the tine 304;

[0052] Further, when the tine 304 is in contact with the cooperating plate 9 through the push rod 10, the tine 304 will be turned counterclockwise through the contact of the push rods 10 on both sides, and when the tine 304 is repeatedly swinging, it will throw the small-sized waste that has been dropped to the position of the fence 5, which will flow out from the gap of the fence 5, thus facilitating subsequent processing, and the waste adhered inside the tine 304 will not fall to the position directly below the tine 304. When the tine 304 enters the water, it will be in contact with the inside of the tine 304 again, and the small-sized waste that has been dropped will be intercepted, lifted and transported by the tine 304, thus avoiding the small-sized waste from being in contact with the tine 304 again, and improving the overall cleanliness of the tine 304 before it enters the water.

[0053] As shown in Figures 7 to 10 one side of the sliding cylinder 603 is fixedly connected with a plurality of insertion rods 604, one end of the insertion rod 604 is slidingly inserted with a fixed sleeve 605, the fixed sleeve 605 is fixedly connected with the side surface of the tine 304, and the sliding cylinder 603 is slidingly connected with one end of the tine 304.

[0054] When working, in order to avoid the tine 304 from being out of position when it is reset after being in contact with the cooperating plates 9 through the push rods 10 on both sides, the tine 304 will not be able to be accurately inserted into the gap of the fence 5, and when the tine 304 is in contact with the cooperating plates 9 through the push rods 10, the tine 304 will also drive the torsional spring 607 to store energy multiple times, thus enabling the tine 304 to swing and turn counterclockwise multiple times. Therefore, while the tine 304 drives the torsional spring 607 to rotate and store energy, the fixed plate 608 will also slide and displace, so that the fixed plate 608 pushes the sliding cylinder 603 to slide in the installation cylinder 602 towards the side close to the tine 304, and the sliding cylinder 603 will drive the insertion rods 604 to be inserted into the fixed sleeve 605 when it slides, so that the sliding cylinder 603 and the tine 304 form an integral whole, and the torsional spring 607 can stably drive the tine 304 to repeatedly spring, thus improving the stability of the tine 304 when it is self-cleaning.

[0055] It should be noted that, since the plug rod 604 is inserted inside the fixed sleeve 605, and the fixed sleeve 605 is fixedly connected with the tines 304, the stability of the sliding cylinder 603 after being inserted into the inside of the fixed sleeve 605 can be improved, and since the plurality of sliding columns 609 on the surface of the tines 304 also slide and frictionally contact the wedge plate 610, the stability of the tines 304 when reciprocating and swinging can be further improved, and since the distance between the plurality of matching plates 9 is close, when the plug rod 604 is inserted into the inside of the fixed sleeve 605, even if the tines 304 are continuously reciprocating and swinging, the plug rod 604 will not fall out of the inside of the fixed sleeve 605, and the stability of the tines 304 when swinging can be effectively improved.

[0056] As shown in Figure 11 The front of the mounting column 1 is provided with a water spraying mechanism 2 for spraying high-pressure wastewater, the water spraying mechanism 2 includes a water spraying pump 201 fixedly connected to one side of the mounting column 1, a water inlet pipe 202 is arranged below the water spraying pump 201, the water inlet pipe 202 is located in the wastewater, and a filter ball is arranged at the lowermost part of the water inlet pipe 202, a water spraying pipe 203 is arranged in the middle of the water spraying pump 201, and the water spraying pipe 203 is arranged in an inclined direction.

[0057] When the tines 304 move downward and continuously contact the matching plates 9 through the push rods 10, the water spraying pump 201 is started to draw wastewater through the filter ball into the inside of the water spraying pump 201 and then transmit it to the position of the water spraying pipe 203, at this time, the wastewater is sprayed into the inside of the reciprocating tines 304 in a high-pressure state, which can wash the dispersed waste, further improve the cleaning effect inside the tines 304, and it should be noted that since the tines 304 are continuously reciprocating at this time, when the high-pressure wastewater is sprayed from the inside of the water spraying pipe 203 to the inside of the tines 304, the tines 304 will swing and hit the dispersed waste and wastewater to the position of the fence 5, and then flow out from the gap of the fence 5, which facilitates subsequent secondary filtration of small-sized waste, and the small-sized waste will not adhere to the gap position of the fence 5, which can improve the pretreatment effect of the fence 5 on the textile wastewater.

[0058] As shown in Figures 4 to 6 A plurality of baffles 706 are rotatably arranged at the sliding position of the telescopic scraper 704 at the bottom of the swinging frame 701 by a pin shaft, the baffles 706 are in a separated state from the inside of the tines 304, and the bottom of the swinging frame 701 is arc-shaped.

[0059] When the telescopic scraper 704 slides out in the interior of the swing frame 701 under the pushing force of the two fixed rods 702 during work, the waste in the gap position of the tines 304 can be scraped, and the cleanliness of the tines 304 is improved. However, when the telescopic scraper 704 slides in the interior of the swing frame 701, the telescopic scraper 704 also moves along a certain circular arc track, and the surface of the telescopic scraper 704 is inevitably adhered with some small waste. When the telescopic scraper 704 slides back in the interior of the swing frame 701, the surface of the telescopic scraper 704 is in contact with the baffle 706, the baffle 706 scrapes the waste adhered to the surface of the telescopic scraper 704, so that the surface of the telescopic scraper 704 is also in a clean state, the effect of the subsequent telescopic scraper 704 on scraping and cleaning the gaps of the plurality of tines 304 is improved, the cleaning effect of the tines 304 is further improved, and the effect of subsequent cleaning of the waste intercepted by the fence 5 is facilitated. It should be noted that the baffle 706 does not contact the arc surface in the interior of the tines 304, and the bottom of the swing frame 701 is arc-shaped. When the swing frame 701 is in contact with the tines 304, the baffle 706 does not interfere with the sliding out of the telescopic scraper 704, and the bottom of the swing frame 701 can effectively discharge the waste lifted and transported on the surface of the tines 304. At this time, the state of the bottom of the swing frame 701 changes from a circular arc to a state of extending out of the telescopic scraper 704, that is, the waste on the arc surface of the tines 304 is changed to the state of scraping the waste in the gap of the tines 304. Before the telescopic scraper 704 slides out of the interior of the swing frame 701, the arc-shaped bottom surface of the swing frame 701 is in contact with the arc surface in the interior of the tines 304. When the telescopic scraper 704 slides out, the arc-shaped bottom surface of the swing frame 701 is in contact with the position of the tines 304 inserted into the fence 5, and the telescopic scraper 704 is located at the gap of the tines 304 at this time.

[0060] As shown in Figures 4 to 5 The upper portion of the swing frame 701 is fixedly connected with a rotating rod 703, the rotating rod 703 is rotationally connected with the mounting plate 8, and a plurality of tension springs 705 are arranged at the included angle position between the swing frame 701 and the mounting plate 8. The tension springs 705 are arc-shaped.

[0061] When the swing frame 701 is swung by the pushing force of the rake tooth 304, the swing frame 701 swings around the axis of the rotating rod 703, and the swing frame 701 swings to stretch the plurality of tension springs 705, so that the tension springs 705 are stretched to store energy. When the swing frame 701 is no longer in contact with the rake tooth 304, the swing frame 701 is reset under the action of the plurality of tension springs 705, and the rotating rod 703 rotates. The plurality of tension springs 705 can reset the swing frame 701, avoid the swing frame 701 from swinging too much to interfere with the fixed rod 702, effectively improve the smoothness of the swing frame 701, and quickly reset the next rake tooth 304 for cleaning.

[0062] As shown in Figures 1 to 3 The installation column 1 is fixedly connected with a collection box 4 for collecting the solid waste discharged by the rake tooth 304. The surface of the transmission shaft 302 is fixedly connected with a protective shell, and the protective shell is provided with a waterproof gasket between the motor 301. The rake tooth 304 is made of high-strength and high-mobility material.

[0063] When the swing frame 701 is swung by the movement of the rake tooth 304, and the rake tooth 304 is swung by the reverse pushing force of the swing frame 701, the solid waste in the rake tooth 304 falls from the inside of the rake tooth 304 to the inside of the collection box 4 for collection. The waste with small volume adhered to the inside of the rake tooth 304 is treated subsequently, flows out from the gap of the fence 5, and is subjected to secondary purification treatment, so that the effect of pretreating the textile wastewater is improved, and the effect of preventing the wastewater from being purified is improved.
