[0003] The patent with application number 202010677119.8 relates to the field of wastewater treatment technology for textile printing and dyeing equipment. Specifically, it is a wastewater treatment device for textile printing and dyeing equipment based on Internet of Things big data technology, including a box, a conveying mechanism, a collecting mechanism, a stirring mechanism, a resistance mechanism, a cleaning mechanism and a filtering mechanism; through the action of the conveying mechanism, the sewage inside the printing and dyeing equipment is transported to the inside of the box for filtration and purification, and at the same time, under the action of the resistance mechanism, it is beneficial to reduce pressure and prevent sewage backflow; under the action of the filtering mechanism, it is beneficial to filter the incoming sewage and block the fluff and debris inside the sewage; at the same time, under the action of the cleaning mechanism, the incoming sewage is stirred, which is beneficial to the dissolution and filtration of debris; under the action of the resistance mechanism, the cleaning mechanism slides on the top of the filtering mechanism, which is beneficial to scrape off the fluff and debris adhering to the top of the filtering mechanism, and enter the collecting mechanism for collection and storage, thereby facilitating subsequent cleaning.

[0004] During the use of the above-mentioned device, if it is necessary to add chemicals for purification, it is easy to add all the chemicals at once, which will cause the chemicals to clump into the sewage, thereby affecting the contact area between the chemicals and the sewage and affecting the purification effect. Therefore, a textile printing and dyeing sewage treatment and reuse device is proposed to solve the above-mentioned problems. Summary of the invention

[0005] The technical problem to be solved by the present invention is to provide a wastewater treatment and reuse device for textile printing and dyeing in view of the deficiencies in the above-mentioned prior art.

The spring telescopic column is fixedly connected to the right side of the pressing plate. The oil barrel is fixedly installed on the circumferential surface of the reaction kettle. The bottom of the pressing plate is in contact with the inner wall of the oil barrel. When the device is started, the pressing plate moves to the right, and the spring telescopic column reciprocates left and right, causing the spring telescopic column to be squeezed and stretched, so as to facilitate the reset of the device. By moving the pressing plate left and right, the medicament inside the oil barrel is indirectly opened and dropped into the sewage, preventing all the medicament from being added at one time, resulting in a reduction in the mixing and purification effect with the sewage. The circumferential surface of the cam is in contact with the contact rod. The right side of the spring telescopic column is fixedly connected to the inner wall of the oil barrel. A notch is opened at the bottom of the inner wall of the oil barrel, and the notch is located below the pressing plate. The rotation of the first connecting plate drives the dosing box to rotate, making the dosing box more evenly put the medicament dropped from the oil barrel into the sewage, accelerating the subsequent fusion speed of the medicament and the sewage, and improving the working efficiency of the machine.

[0007] Preferably, the stirring device includes a second connecting plate, an L-shaped plate, a first fixing plate, a second rotating rod, and a first roller. The second connecting plate is fixedly connected to the circumferential surface of the first rotating rod. The L-shaped plate is fixedly connected to the circumferential surface of the second connecting plate. The impurities in the inner wall of the reaction kettle are scraped off by the rotation of the L-shaped plate to prevent the impurities from adhering to the inner wall of the reaction kettle and affecting the subsequent purification effect. The first fixing plate is fixedly connected to the bottom of the L-shaped plate. The second rotating rod is rotatably connected to the inner wall of the first fixing plate. The first roller is fixedly connected to the circumferential surface of the second rotating rod. The stirring device further includes a stirring plate, a guiding block, a sieve plate, a second fixing plate, and a first hinged plate. The stirring plate is fixedly connected to the circumferential surface of the second rotating rod. The first roller rotates by friction. The sieve plate screens the impurities in the sewage to prevent the impurities in the sewage from affecting the filtering effect. The stirring plate rotates to fully stir and mix the dropped medicament and the sewage, accelerating the reaction time between the medicament and the sewage. The guiding block is fixedly connected to the outer wall of the stirring plate. The sieve plate is fixedly installed on the inner wall of the reaction kettle. The second fixing plate is fixedly connected to the front part of the L-shaped plate. The first hinged plate is fixedly connected to the outer wall of the second fixing plate through a torsion spring. The front part of the guiding block contacts the rear part of the first hinged plate. The circumferential surface of the first roller contacts the top of the sieve plate. The swinging of the first hinged plate further enhances the reaction efficiency between the medicament and the sewage.

[0008] Preferably, the cleaning device includes a third fixing plate, a second roller, a third rotating rod, a top rod, a sieve plate, a second hinge plate, a collection box, a third hinge plate, a limiting plate, and a fourth hinge plate. The third fixing plate is fixedly connected to the surface of the L-shaped plate. The second roller is in contact with the inner wall of the reaction kettle. The third rotating rod is fixedly connected to the inner wall of the second roller. The fourth hinge plate is movably connected to the circumferential surface of the third rotating rod. The top rod is fixedly connected to the bottom of the fourth hinge plate. The bottom of the sieve plate is in contact with the sieve plate.

The third hinge plate is rotatably connected to the inner wall of the sieve plate through a torsion spring. The limiting plate is fixedly connected to the top of the third hinge plate. The outer wall of the fourth hinge plate is in contact with the inner wall of the sieve plate. The circumferential surface of the third rotating rod is rotatably connected to the inner wall of the sieve plate. The surface of the third rotating rod is provided with a cross-shaped spiral groove. The inner wall of the fourth hinge plate is provided with a block, and the block is located in the cross-shaped spiral groove. The surface of the fourth hinge plate is provided with a cross-shaped spiral groove. The inner wall of the fourth hinge plate is provided with a block, and the block is located in the cross-shaped spiral groove. The fourth hinge plate is composed of a left plate and a right plate, and a torsion spring is arranged between the left plate and the right plate. The left plate is movably connected to the third rotating rod. The right plate is in contact with the second sieve plate. The left plate is fixedly connected to the top rod. When the fourth hinge plate moves downward, it drives the top rod to move downward. During this process, the right plate of the fourth hinge plate will contact and push the third hinge plate to rotate downward, so that the fourth hinge plate can cross the third hinge plate. When the top rod moves downward, it will contact the second hinge plate and push the second hinge plate to open, so that the down cotton scraped by the right plate of the fourth hinge plate falls into the collection box. When the fourth hinge plate moves upward and resets, the right plate of the fourth hinge plate will be blocked by the third hinge plate limited by the limiting plate, so that the right plate rotates. After the right plate rotates and moves upward to reset, it can reduce the contact between the right plate and the second sieve plate, preventing the right plate from pushing the newly filtered down cotton to the upper part.

[0009] Adopting the above technical solution, the present invention can bring the following beneficial effects: 1. For the textile printing and dyeing wastewater treatment and reuse device, through the coordinated operation of the motor, the first rotating rod, the cam, the round block, the first connecting plate, the material spreading box, the contact rod, the extrusion plate, the spring telescopic column, and the oil barrel, when the device starts, the extrusion plate moves to the right. The spring telescopic column moves left and right reciprocally, so that the spring telescopic column is squeezed and stretched, facilitating the reset of the device. When the extrusion plate moves left and right, the medicament inside the oil barrel is intermittently opened and dropped into the sewage, preventing all the medicament from being added at one time, which may reduce the mixing and purification effect with the sewage. The first connecting plate rotates to drive the material spreading box to rotate, making the medicament dropped from the oil barrel by the material spreading box more evenly distributed into the sewage, thus accelerating the fusion speed of the medicament and the sewage subsequently and improving the working efficiency of the machine.

[0010] 2. For the sewage treatment and reuse device for textile printing and dyeing, through the coordinated operation among the second connecting plate, L-shaped plate, first fixing plate, second rotating rod, first roller, stirring plate, guiding block, sieve plate, second fixing plate, and first hinged plate, when the device is started, the impurities on the inner wall of the reaction kettle are scraped off by the rotation of the L-shaped plate, preventing the impurities from adhering to the inner wall of the reaction kettle and affecting the subsequent purification effect. The first roller rotates due to friction, and the sieve plate screens the impurities in the sewage to prevent the impurities in the sewage from affecting the filtering effect. The stirring plate rotates to fully stir and blend the dropped medicament with the sewage, accelerating the reaction time between the medicament and the sewage. The swinging of the first hinged plate further enhances the reaction efficiency between the medicament and the sewage.

[0011] 3. For the sewage treatment and reuse device for textile printing and dyeing, through the coordinated operation among the third fixing plate, second roller, third rotating rod, ejector rod, sieve plate, second hinged plate, collection box, third hinged plate, and limiting plate, when the sieve plate rotates, the floating down cotton on the water surface is removed by the sieve plate. The fourth hinged plate moves downward to scrape the down cotton on the second sieve plate. When the fourth hinged plate moves downward, it drives the ejector rod to move downward. During this process, the right plate of the fourth hinged plate will contact and push the third hinged plate to rotate downward, enabling the fourth hinged plate to cross over the third hinged plate. When the ejector rod moves downward, it will contact the second hinged plate, causing the second hinged plate to be pushed open, allowing the down cotton scraped by the right plate of the fourth hinged plate to fall into the collection box. When the fourth hinged plate moves upward and resets, the right plate of the fourth hinged plate will be blocked by the third hinged plate limited by the limiting plate, causing the right plate to rotate. After the right plate rotates and moves upward to reset, it can reduce the contact with the second sieve plate, preventing the right plate from pushing the newly filtered down cotton to the upper part.

When the device is started, the first rotating rod 202 is driven to rotate by the motor 201, the rotation of the first rotating rod 202 drives the cam 203 to rotate. When the cam 203 rotates, it will contact the contact rod 207, causing the contact rod 207 to move to the right. The rightward movement of the contact rod 207 drives the pressing plate 208 to move to the right. The rightward movement of the pressing plate 208 causes the spring telescopic column 209 to move back and forth left and right through the spring telescopic column 209, so that the spring telescopic column 209 is squeezed and stretched to facilitate the reset of the device. The intermittent opening and dropping of the medicament inside the oil barrel 210 into the sewage by the left and right movement of the pressing plate 208 prevents all the medicament from being added at one time, resulting in a reduction in the mixing and purification effect with the sewage. The circumferential surface of the cam 203 is in contact with the contact rod 207, the right side of the spring telescopic column 209 is fixedly connected to the inner wall of the oil barrel 210, and a notch is opened at the bottom of the inner wall of the oil barrel 210, and the notch is located below the pressing plate 208. The rotation of the round block 204 drives the first connecting plate 205 to rotate, and the rotation of the first connecting plate 205 drives the dosing box 206 to rotate, making the dosing box 206 more evenly put the medicament dropped from the oil barrel 210 into the sewage, which speeds up the fusion speed of the medicament and the sewage subsequently and improves the working efficiency of the machine.

[0016] Working principle: When the device is started, the rotating rod one 202 is driven to rotate by the motor 201. The rotation of the rotating rod one 202 drives the cam 203 to rotate. When the cam 203 rotates, it will contact the contact rod 207, causing the contact rod 207 to move to the right. The rightward movement of the contact rod 207 drives the pressing plate 208 to move to the right. The rightward movement of the pressing plate 208 causes the spring telescopic column 209 to move back and forth left and right through the spring telescopic column 209, so that the spring telescopic column 209 is squeezed and stretched to facilitate the reset of the device. The left and right movement of the pressing plate 208 causes the agent inside the oil barrel 210 to be intermittently opened and dropped into the sewage, preventing the phenomenon of adding all the agents at one time, which may lead to the agglomeration of the agents into the sewage, thereby affecting the contact area between the agent and the sewage, reducing the purification effect, and resulting in a decrease in the mixed purification effect with the sewage. The rotation of the rotating rod one 202 drives the round block 204 to rotate, the rotation of the round block 204 drives the connecting plate one 205 to rotate, and the rotation of the connecting plate one 205 drives the material spreading box 206 to rotate, making the material spreading box 206 more evenly put the agent dropped from the oil barrel 210 into the sewage, accelerating the subsequent fusion speed of the agent and the sewage, and improving the working efficiency of the machine.

The first sieve plate 308 is fixedly installed on the inner wall of the reaction kettle 1. When the device is started, the rotation of the first rotating rod 202 drives the rotation of the second connecting plate 301. The rotation of the second connecting plate 301 drives the rotation of the L-shaped plate 302. The rotation of the L-shaped plate 302 scrapes the impurities on the inner wall of the reaction kettle 1 to prevent the impurities from adhering to the inner wall of the reaction kettle 1 and affecting the subsequent purification effect. The rotation of the L-shaped plate 302 drives the rotation of the first fixing plate 303. When the first fixing plate 303 rotates, it drives the rotation of the first roller 305. When the first roller 305 rotates and moves, it will contact the bottom first sieve plate 308, causing the first roller 305 to rotate by friction.

The rotation of the stirring plate 306 fully stirs and mixes the dropped medicament and the sewage, accelerating the reaction time between the medicament and the sewage. The rotation of the stirring plate 306 drives the rotation of the guiding block 307. When the guiding block 307 rotates, it will contact the first hinged plate 310, causing the first hinged plate 310 to swing. At the same time, after the first hinged plate 310 swings, it is reset by the torsion spring. The swinging of the first hinged plate 310 further enhances the reaction efficiency between the medicament and the sewage.

[0018] The cleaning device 4 includes a third fixed plate 401, a second roller 402, a third rotating rod 403, a ejector rod 404, a second sieve plate 405, a second hinge plate 406, a collection box 407, a third hinge plate 408, a limiting plate 409, and a fourth hinge plate 410. The third fixed plate 401 is fixedly connected to the surface of the L-shaped plate 302. The second roller 402 is in contact with the inner wall of the reaction kettle 1.

The fourth hinge plate 410 is movably connected to the circumferential surface of the third rotating rod 403. The ejector rod 404 is fixedly connected to the bottom of the fourth hinge plate 410. The bottom of the second sieve plate 405 is in contact with the first sieve plate 308. By rotating the L-shaped plate 302 to drive the third fixed plate 401 to rotate, when the third fixed plate 401 rotates, it drives the second sieve plate 405 to rotate. When the second sieve plate 405 rotates, it drives the second roller 402 to rotate. When the second roller 402 rotates, it drives the third rotating rod 403 to rotate accordingly. When the second sieve plate 405 rotates, the second sieve plate 405 removes the down cotton floating on the water surface. Through the third rotating rod 403, the cross-shaped spiral groove drives the fourth hinge plate 410 to move downward. When the fourth hinge plate 410 moves downward, it scrapes the down cotton on the second sieve plate 405. The collection box 407 is fixedly connected to the inner wall of the second sieve plate 405. The second hinge plate 406 is hinged to the inner wall of the collection box 407 through a torsion spring. The third hinge plate 408 is rotatably connected to the inner wall of the second sieve plate 405 through a torsion spring. The limiting plate 409 is fixedly connected to the top of the third hinge plate 408. The outer wall of the fourth hinge plate 410 is in contact with the inner wall of the second sieve plate 405. The circumferential surface of the third rotating rod 403 is rotatably connected to the inner wall of the second sieve plate 405. The surface of the third rotating rod 403 is provided with a cross-shaped spiral groove. The inner wall of the fourth hinge plate 410 is provided with a clamping block, and the clamping block is located in the cross-shaped spiral groove. The fourth hinge plate 410 is composed of a left plate and a right plate, and a torsion spring is provided between the left plate and the right plate. The left plate is movably connected to the third rotating rod 403. The right plate is in contact with the second sieve plate 405. The left plate is fixedly connected to the ejector rod 404. When the fourth hinge plate 410 moves downward, it drives the ejector rod 404 to move downward. When the ejector rod 404 moves downward, it will contact the second hinge plate 406, causing the second hinge plate 406 to move downward and reset through the torsion spring at the same time. By scraping the down cotton into the collection box 407, when the third hinge plate 408 moves downward and contacts and compresses, when the third hinge plate 408 returns upward, it is limited by the limiting plate 409, causing the hinge joint of the fourth hinge plate 410 to rotate and drop the upper layer of down cotton.

[0019] Working principle: When the device starts, the rotation of the first rotating rod 202 drives the rotation of the second connecting plate 301, and the rotation of the second connecting plate 301 drives the rotation of the L-shaped plate 302. Through the rotation of the L-shaped plate 302, the impurities in the inner wall of the reactor 1 are scraped off to prevent the impurities from adhering to the inner wall of the reactor 1 and affecting the subsequent purification effect. The rotation of the L-shaped plate 302 drives the rotation of the first fixing plate 303, and when the first fixing plate 303 rotates, it drives the rotation of the first roller 305. When the first roller 305 rotates and moves, it will contact the bottom first sieve plate 308, causing the first roller 305 to rotate by friction. The first sieve plate 308 screens the impurities in the sewage to prevent the impurities in the sewage from affecting the filtration effect. The rotation of the first roller 305 drives the rotation of the second rotating rod 304, and through the rotation of the second rotating rod 304, it drives the rotation of the stirring plate 306. The rotation of the stirring plate 306 fully stirs and mixes the dropped medicament with the sewage, accelerating the reaction time between the medicament and the sewage. The rotation of the stirring plate 306 drives the rotation of the guiding block 307, and when the guiding block 307 rotates, it will contact the first hinged plate 310, causing the first hinged plate 310 to swing. At the same time, after the first hinged plate 310 swings, it is reset by the torsion spring. The swinging of the first hinged plate 310 further enhances the reaction efficiency between the medicament and the sewage.

[0020] Through the rotation of the L-shaped plate 302, it drives the rotation of the third fixing plate 401, so that when the third fixing plate 401 rotates, it drives the rotation of the second sieve plate 405. The rotation of the second sieve plate 405 drives the rotation of the second roller 402, and when the second roller 402 rotates, it drives the third rotating rod 403 to rotate accordingly. When the second sieve plate 405 rotates, the second sieve plate 405 removes the floating down cotton on the water surface. Through the third rotating rod 403, the cross-type spiral groove drives the fourth hinged plate 410 to move downward. The downward movement of the fourth hinged plate 410 scrapes the down cotton on the second sieve plate 405. The downward movement of the fourth hinged plate 410 drives the downward movement of the ejector rod 404. During this process, the right plate of the fourth hinged plate 410 will contact the third hinged plate 408 and push it to rotate downward, so that the fourth hinged plate 410 can cross over the third hinged plate 408. The downward movement of the ejector rod 404 will contact the second hinged plate 406, causing the second hinged plate 406 to be pushed open by it, allowing the down cotton scraped by the right plate of the fourth hinged plate 410 to fall into the collection box 407. When the fourth hinged plate 410 moves upward and resets, the right plate in the fourth hinged plate 410 will be blocked by the third hinged plate 408 limited by the limiting plate 409, causing the right plate to rotate. After the right plate rotates, it moves upward and resets, which can reduce the contact between the right plate and the second sieve plate 405 and prevent the right plate from pushing the newly filtered down cotton to the upper part.

[0021] The present invention provides a sewage treatment and reuse device for textile printing and dyeing. There are many methods and ways to specifically implement this technical solution. The above is only the preferred embodiment of the present invention. It should be noted that for those of ordinary skill in the art of this technology, without departing from the principle of the present invention, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present invention. Each component not clearly defined in this embodiment can be implemented by existing technologies.
