Description

Technical Field

[0001] This invention relates to the field of wastewater treatment technology, specifically to an environmentally friendly wastewater treatment device for textile printing and dyeing workshops. Background Technology

[0002] Wastewater treatment equipment in textile printing and dyeing workshops needs to be highly efficient, reliable, and environmentally friendly to effectively treat the generated wastewater and ensure that the discharged water quality meets the requirements of environmental regulations. Patent publication number CN216106447U relates to an environmentally friendly wastewater treatment device for textile printing and dyeing workshops. The device includes a wastewater treatment tank with a first and second partition fixedly connected to its inner wall. A sedimentation zone is formed by one side of the first partition and one side of the inner wall of the wastewater treatment tank, and a settling mechanism is installed inside the sedimentation zone. This environmentally friendly wastewater treatment device for textile printing and dyeing workshops, through the settling mechanism, includes a motor, support base, roller, capillary pores, a fixing block, a rotating shaft, and polyaluminum chloride (PAC). Wastewater sprayed from a first nozzle drives the roller to rotate. Simultaneously, wastewater enters the roller through the capillary pores and combines with the PAC. The motor drives the rotating shaft to rotate, and the rotating shaft further facilitates the thorough mixing of the wastewater entering the roller through the capillary pores with the PAC. The rotation of the roller allows the dissolved PAC solution to permeate into the wastewater through the capillary pores, ensuring full contact between the solution and the wastewater, thus achieving a sedimentation effect.

[0003] In the aforementioned patent, the wastewater entering the drum through capillary pores is fully mixed with polyaluminum chloride by a rotating shaft. The rotation of the drum allows the dissolved polyaluminum chloride solution to permeate into the wastewater through the capillary pores. The rotation of the drum allows the solution to fully contact the wastewater, achieving a sedimentation effect. However, during the initial treatment of the wastewater, large impurities in the wastewater can affect subsequent processing. If the impurities are not effectively filtered, the effect of subsequent processing will be affected, impacting work efficiency and pass rate. Summary of the Invention

The fixed end of the elastic telescopic rod is fixedly installed at the bottom of the L-shaped rod, and the scraper is fixedly installed at the bottom of the output end of the elastic telescopic rod.

[0006] According to the above technical solution, the scraper contacts the filter screen, the surface of the filter tank is provided with a sliding groove, and the L-shaped plate slides in the sliding groove.

[0007] According to the above technical solution, the arc-shaped plate is fixedly installed on the inner wall of the filter tank, the sliding rod is fixedly installed on the inner wall of the filter tank, the rotating rod is rotatably installed on the surface of the sliding rod, and the limiting rod is fixedly installed at the bottom of the sliding rod. Due to the limiting rod's limitation on the rotating plate, the limiting plate cannot rotate to the bottom.

[0008] According to the above technical solution, the side of the limiting rod that contacts the rotating rod is set as an inclined surface, and the arc-shaped plate contacts the scraper.

[0009] According to the above technical solution, the material mixing device includes: a storage tank, a support column, a large gear, a support rod, a small gear, a connecting rod, a mixing device, and a feed pipe. The storage tank is fixedly installed at the bottom of the top cover, the support column is fixedly installed at the bottom of the top cover, the large gear is fixedly installed at the bottom of the support column, the support rod is fixedly installed on the circumferential surface of the mixing rod, a rotating hole is opened on the surface of the support rod, the connecting rod is sleeved on the inner wall of the rotating hole, the small gear is fixedly installed at one end of the connecting rod, and the rotation of the small gear will drive the connecting rod to rotate. The small gear meshes with the large gear. The mixing device is fixedly installed at the other end of the connecting rod, and the rotation of the connecting rod will drive the mixing device to rotate. The feed pipe passes through and is fixedly installed on the surface of the top cover, and the feed pipe passes through the circumferential surface of the storage tank.

[0010] According to the above technical solution, the tamping device is in contact with the storage tank, and the bottom of the storage tank is provided with a discharge hole.

[0011] According to the above technical solution, the material spreading device includes: a spreading trough, a rotating rod, a ring, a rotating plate, and a clearing rod. The spreading trough is installed through and fixedly on the circumferential surface of the mixing rod. The rotation of the mixing rod will drive the spreading trough to rotate. One end of the rotating rod is rotatably installed on the circumferential surface of the mixing rod. The rotation of the mixing rod will drive the rotating rod to rotate. The ring is rotatably installed on the other end of the rotating rod. The rotating plate is fixedly installed on the top of the rotating rod. The clearing rod is rotatably installed on the surface of the rotating plate.

[0012] According to the above technical solution, the circumferential surface of the spreading groove is provided with spreading holes, and the ring is in contact with the inner wall of the spreading groove.

[0013] This invention provides an environmentally friendly wastewater treatment device for textile printing and dyeing workshops. It has the following beneficial effects: (1) In this invention, sewage flows into the filter tank through the inlet pipe, and impurities will be stuck on the surface of the filter screen. This can effectively filter the impurities in the sewage, prevent large impurities from affecting subsequent processing, and ensure the qualification rate of subsequent processing. The linear motor moves, which drives the L-shaped rod to move. The L-shaped rod moves, which drives the scraper to move. The scraper moves, which pushes the impurities on the surface of the filter screen to the sewage outlet. This can effectively clean the filtered impurities, prevent excessive accumulation of impurities from causing poor sewage discharge effect, and improve work efficiency. When the scraper moves, it will contact the arc plate. The arc plate lifts the scraper by its own arc surface and separates it from the filter screen. Then the scraper continues to move along the rotating plate. The rotating plate cannot rotate to the bottom due to the limit rod. This prevents the scraper from scraping the impurities away from the sewage outlet when it moves away from the sewage outlet, which would make it impossible to effectively clean the impurities and improve the practicality of the device.

[0014] (2) In this invention, when the rotary motor is started, the output end of the rotary motor will rotate and drive the stirring rod to rotate. The rotation of the stirring rod will stir the sewage in the shell, which improves the fusion effect of sewage and regulator. When the regulator is poured into the feed pipe, the rotation of the stirring rod will drive the connecting rod to rotate. The rotation of the connecting rod will drive the tamping device to rotate along the bottom of the storage tank and crush the regulator, preventing the regulator from clumping and failing to fully blend with the sewage, thus failing to meet the expected requirements and improving stability.

[0015] (3) In this invention, the conditioner is crushed and poured into the spreading trough. The rotation of the stirring rod will drive the spreading trough to rotate. The rotation of the spreading trough will cause the conditioner to be spread out through the spreading hole through the centrifugal force generated by the rotation, so that the spreading range of the conditioner is wider and the fusion rate of the conditioner and the sewage is improved. The rotation of the stirring rod will drive the rotating rod to rotate. The rotation of the rotating rod will drive the ring to move. After the ring moves, it will no longer block the spreading hole. This allows the stirring rod to open the spreading hole when the rotation speed is the fastest and the conditioner to be added when the stirring rod has the most thorough stirring effect, which effectively improves the fusion efficiency. The movement of the rotating rod will drive the unblocking rod to move. The movement of the unblocking rod will unblock the discharge hole and prevent the conditioner from accumulating too much in the discharge hole and causing blockage, thus improving the practicality of the device.

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0019] Please see Figures 1-5 One embodiment of the present invention is: an environmentally friendly wastewater treatment device for textile printing and dyeing workshops, including a shell 1, a top cover 2 fixedly installed on the top of the shell 1, a water inlet pipe 3 through and fixedly installed on the top of the shell 1, a sewage outlet 4 fixedly installed on the right side of the shell 1, a rotary motor 5 provided on the top of the top cover 2, a stirring rod 6 fixedly installed at the output end of the rotary motor 5, the stirring rod 6 through and rotatably installed on the inner and outer walls of the top cover 2, and a filter device provided inside the shell 1; The filtration device includes: a filter tank 71, a filter screen 72, a linear motor 73, an L-shaped rod 74, an elastic telescopic rod 75, a scraper 76, an arc-shaped plate 77, a sliding rod 78, a rotating rod 79, and a limiting rod 710. The filter tank 71 is fixedly installed on the inner wall of the outer casing 1, the filter screen 72 is fixedly installed on the inner wall of the filter tank 71, the linear motor 73 is disposed on the surface of the outer casing 1, the L-shaped rod 74 is fixedly installed on the surface of the linear motor 73, the fixed end of the elastic telescopic rod 75 is fixedly installed at the bottom of the L-shaped rod 74, and the scraper 76 is fixedly installed at the bottom of the output end of the elastic telescopic rod 75. This device can effectively clean the filtered impurities, prevent excessive accumulation of impurities from causing poor sewage discharge, and improve work efficiency.

[0020] The scraper 76 contacts the filter screen 72, and a sliding groove is provided on the surface of the filter tank 71.

[0021] The arc-shaped plate 77 is fixedly installed on the inner wall of the filter tank 71, the sliding rod 78 is fixedly installed on the inner wall of the filter tank 71, the rotating rod 79 is rotatably installed on the surface of the sliding rod 78, and the limiting rod 710 is fixedly installed on the bottom of the sliding rod 78. This ensures that the scraper 76 no longer contacts the filter screen 72 when it moves away from the drain port 4, preventing the scraper 76 from scraping impurities away from the drain port 4 when it moves away from the drain port 4, thus preventing ineffective cleaning of impurities and improving the practicality of the device.

[0022] The side of the limiting rod 710 that contacts the rotating rod 79 is set as an inclined surface, and the arc plate 77 contacts the scraper 76.

[0023] In this embodiment, during operation: wastewater flows into the filter tank 71 through the inlet pipe 3. Large impurities in the wastewater will be stuck in the slots of the filter screen 72, effectively filtering the impurities and ensuring the pass rate of subsequent processing. The linear motor 73 moves towards the drain port 4, which drives the L-shaped rod 74 to move towards the drain port 4. The movement of the L-shaped rod 74 drives the elastic telescopic rod 75 to move, which in turn drives the scraper 76 to move. The movement of the scraper 76 scrapes the impurities filtered on the surface of the filter screen 72 to the drain port 4 for discharge, effectively cleaning the filtered impurities and preventing excessive accumulation of impurities that would lead to poor sewage discharge, thus improving work efficiency. When the scraper 76 moves to the drain port 4, it will contact the arc plate 77. The scraper 76 will be lifted by its own arc surface, and the scraper 76 will continue to move along the arc surface of the arc plate 77. As the scraper 76 continues to move and detach from the filter screen 72, after it reaches the outermost edge, the linear motor 73 moves away from the drain outlet 4. The linear motor 73 moves the L-shaped rod 74, which in turn moves the elastic telescopic rod 75. The elastic telescopic rod 75 then moves the scraper 76. The scraper 76 moves along the rotating plate 79. Due to the limiting rod 710's restriction on the rotating plate 79, the limiting plate 79 cannot rotate to the bottom. The scraper 76 then contacts the sliding rod 78 and continues to move along it. This prevents the scraper 76 from contacting the filter screen 72 as it moves away from the drain outlet 4, thus preventing it from scraping impurities away from the drain outlet 4 and thus improving the device's practicality.

[0024] Please see Figures 1-8 Based on the above embodiments, in another embodiment of the present invention, the inner shell 1 is provided with a tamping device and a spreading device. The tamping device includes: a storage tank 81, a support column 82, a large gear 83, a support rod 84, a small gear 85, a connecting rod 86, a tamping device 87, and a feed pipe 88. The storage tank 81 is fixedly installed at the bottom of the top cover 2, the support column 82 is fixedly installed at the bottom of the top cover 2, the large gear 83 is fixedly installed at the bottom of the support column 82, the support rod 84 is fixedly installed on the circumferential surface of the stirring rod 6, a rotating hole is opened on the surface of the support rod 84, the connecting rod 86 is sleeved on the inner wall of the rotating hole, the small gear 85 is fixedly installed at one end of the connecting rod 86, the small gear 85 meshes with the large gear 83, the tamping device 87 is fixedly installed at the other end of the connecting rod 86, and the feed pipe 88 penetrates and is fixedly installed on the surface of the top cover 2. The feed pipe 88 penetrates the circumferential surface of the storage tank 81 to prevent the regulator from clumping and failing to fully mix with the sewage, thus failing to meet the expected requirements and improving stability.

[0025] The tamping device 87 is in contact with the storage tank 81, and the bottom of the storage tank 81 is provided with a discharge hole.

[0026] The spreading device includes: a spreading trough 91, a rotating rod 92, a ring 93, a rotating plate 94, and a clearing rod 95. The spreading trough 91 is installed through and fixedly on the circumferential surface of the mixing rod 6, which makes the spread range of the regulator wider and improves the fusion rate of the regulator and the sewage. One end of the rotating rod 92 is rotatably installed on the circumferential surface of the mixing rod 6, and the ring 93 is rotatably installed on the other end of the rotating rod 92. This allows the mixing rod 6 to open the spreading hole when the rotation speed is the fastest and to spread the regulator when the mixing effect of the mixing rod 6 is the most complete, which effectively improves the fusion efficiency. The rotating plate 94 is fixedly installed on the top of the rotating rod 92, and the clearing rod 95 is rotatably installed on the surface of the rotating plate 94 to prevent excessive accumulation of regulator in the discharge hole and blockage, thus improving the practicality of the device.

[0027] The circumferential surface of the material spreading groove 91 is provided with a material spreading hole, and the ring 93 is in contact with the inner wall of the material spreading groove 91.

[0028] In this embodiment, during operation: The rotary motor 5 is started, and the output of the rotary motor 5 rotates, driving the stirring rod 6 to rotate. The rotation of the stirring rod 6 stirs the wastewater inside the outer shell 1, improving the mixing effect between the wastewater and the regulator. The regulator is poured into the feed pipe 88, and the regulator enters the storage tank 81 through the feed pipe 88. The rotation of the stirring rod 6 drives the support rod 84 to rotate, which in turn drives the connecting rod 86 to rotate. The rotation of the connecting rod 86 drives the pinion 85 to rotate, which in turn drives the connecting rod 86 to rotate. The rotation of the connecting rod 86 drives the compactor 87 to rotate, which crushes the regulator in the storage tank 81, preventing the regulator from clumping and failing to fully mix with the wastewater, thus improving stability.

[0029] After being crushed, the regulator is discharged through the discharge hole into the spreading trough 91. The rotation of the stirring rod 6 drives the spreading trough 91 to rotate. The centrifugal force generated by the rotation of the spreading trough 91 spreads the regulator through the spreading hole, making the spread area of ​​the regulator wider and improving the mixing rate of the regulator with the sewage. The rotation of the stirring rod 6 drives the rotating rod 92 to rotate. After the stirring rod 6 rotates to a sufficient speed, the centrifugal force generated will drive the rotating rod 92 to rotate upward. The movement of the rotating rod 92 will drive the ring 93 to move upward. After the ring 93 moves, it will no longer block the spreading hole, so that the stirring rod 6 can open the spreading hole when the rotation speed is the fastest. The regulator is then added when the stirring rod 6 has the most thorough mixing effect, which effectively improves the mixing efficiency. When the rotating rod 92 moves upward, it will drive the unblocking rod 95 to move. The movement of the unblocking rod 95 will unblock the discharge hole, preventing excessive accumulation of regulator in the discharge hole and causing blockage, thus improving the practicality of the device.

[0030] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
