Description

Technical Field

[0001] The invention relates to the technical field of printing and dyeing wastewater treatment, in particular to a device for treating wastewater after printing and dyeing of bedding knitwear. Background Art

[0002] Knitted fabrics are made by bending yarns into loops and interlacing them with knitting needles. They are divided into warp knitted fabrics and weft knitted fabrics. They are soft, breathable, sweat-wicking and warm, and most of them have excellent elasticity and extensibility. Textile printing and dyeing wastewater consists of dyeing, printing, finishing and other links. The wastewater contains a large amount of dyes, auxiliaries, pulp organic matter and heavy metal harmful substances. If these wastewaters are discharged directly without treatment, they will cause serious pollution to the environment and affect the ecological balance.

The detergent and wastewater will form scum when combined. The scum is usually treated by manual salvage. The staff needs to use a sieve to filter out the scum, and then use the sieve to fish out the remaining scum. However, this treatment method is cumbersome and inefficient, and is difficult to apply to large-scale wastewater treatment after the printing and dyeing of bedding knitwear.

[0036] The tank body 2 is composed of a top frame 21, a bottom bucket 22 and a drain pipe 23, wherein the tripod 42 is welded to the outer wall of the top frame 21, and the sewage in the tank body 2 is treated in the top frame 21 and the bottom bucket 22 and then discharged from the drain pipe 23. The sewage and the cleaning agent are introduced into the tank body 2, wherein the top frame 21 and the bottom bucket 22 are mainly used to mix the sewage and the cleaning agent, so that the mixed sewage and the cleaning agent can fully react in the top frame 21 and the bottom bucket 22 to generate scum, and the scum will float on the surface of the water body, and the purified sewage is located at the bottom of the tank body 2 and is discharged through the drain pipe 23.

[0037] The coaxial linkage mechanism 3 is utilized to synchronously drive the inner rod 37 and the outer pipe 39 to rotate at different speeds, and can be directly connected with the sewage discharge mechanism 4 and the cleaning return flow mechanism 5 while stirring the wastewater. Based on the coaxial linkage mechanism 3, the sewage discharge mechanism 4 and the cleaning return flow mechanism 5 are assisted to realize the automatic treatment of the scum in the wastewater and the related structures for washing and treating the scum, which has the characteristics of high degree of automation, fast scum treatment efficiency and extended service life of the treatment structure.

[0038] See also Figure 4-5In the embodiment of the present invention, the coaxial linkage mechanism 3 is composed of a gear frame 31, a servo motor 32, a gear column 33, a top gear 34, a bottom gear 35, an inner rod traction gear 36, an inner rod member 37, an outer tube traction gear 38, and an outer tube member 39, wherein the gear frame 31 is arranged at the top of the pool body 2, and the servo motor 32 is fixedly connected to the top outer wall of the gear frame 31. The gear frame 31 is used to locate the specific positions of the top gear 34, the bottom gear 35, the inner rod traction gear 36, and the outer tube traction gear 38, so as to facilitate the interaction between the gears. The gear column 33 is fixedly connected to the output shaft of the servo motor 32 through a coupling. The servo motor 32 is the main driving device, and the coupling is used as a docking structure, so that the servo motor 32 can drive the gear column 33 to rotate together. The top gear 34 and the bottom gear 35 are both installed on the outer wall of the gear column 33, wherein the top gear 34 is located at the top of the bottom gear 35. The top gear 34 and the bottom gear 35 rotate together with the gear column 33. The inner rod traction gear 36 and the outer tube traction gear 38 are meshed with the outer walls of the top gear 34 and the bottom gear 35, respectively. The inner rod 37 is fixedly connected to the inner wall of the inner rod traction gear 36, and the outer tube 39 is fixedly connected to the outer wall of the bottom of the outer tube traction gear 38. The inner rod 37 is arranged inside the outer tube 39, and both the inner rod 37 and the outer tube 39 are rotatably connected to the inner wall of the gear frame 31. The size of the inner rod traction gear 36 is smaller than that of the outer tube traction gear 38. The top gear 34 drives the inner rod traction gear 36 to rotate together, and the bottom gear 35 drives the outer tube traction gear 38 to rotate. In this process, since the inner rod 37 and the outer tube 39 are fixed to the inner rod traction gear 36 and the outer tube traction gear 38, respectively, when the output shaft of the servo motor 32 rotates, the inner rod 37 and the outer tube 39 will also rotate together, wherein the inner rod 37 is responsible for stirring the sewage, and the outer tube 39 is used to install the corresponding slag discharge structure.

[0039] See also Figure 6-7In the embodiment of the present invention, the sewage discharge mechanism 4 includes a baffle plate 41 fixedly connected to the outer wall of one side of the outer pipe 39 by screws. The baffle plate 41 is fixed to the outer pipe 39 and rotates with the outer pipe 39. Under the action of the screen holes inside the baffle plate 41, it can not only intercept the scum floating on the water surface, but also will not hinder the sewage from passing through the holes. A tripod 42 is welded to one side of the outer periphery of the pool body 2, and a limit frame 43 is welded to the outer wall of one side of the tripod 42. The tripod 42 is used as an assembly structure, mainly for fixing the limit frame 43 to the pool body 2. A scraper 44 is slidably connected to the inner wall of the limit frame 43. When the baffle plate 41 approaches and squeezes the scraper 44, the scraper 44 can slide on the inner wall of the limit frame 43. The scraper 44 is fixedly connected to the spring coil spring 45 on the outer wall at the bottom of the limit frame 43, and the outer wall of one end of the spring coil spring 45 is fixedly connected to the bottom of the end of the scraper 44. The spring coil 45 is used to reset the scraper 44. When the scraper 44 is squeezed to the end by the baffle plate 41, the baffle plate 41 will pass through the scraper 44. At this time, the scraper 44 can be reset to the initial position by utilizing the rebound effect of the spring coil 45.

[0040] With the coordinated cooperation of the four gears inside the gear frame 31, the outer tube 39 can rotate at a relatively low speed along the center of the inner wall of the top frame 21, thereby controlling the baffle plate 41 to cyclically intercept the scum floating on the water surface. As the baffle plate 41 continues to rotate, under the blocking action of the scraper 44, the scraper 44 can scrape off the scum on the surface of the baffle plate 41 while reducing the wastewater treatment area formed between the scraper 44, the baffle plate 41 and the top frame 21, so that a large amount of scum can be treated at one time, and the scraper 44 can be repeatedly reset by the rebound effect of the clockwork coil spring 45, thereby realizing an automatic cyclic scum removal treatment method, which can be applicable to large-scale wastewater treatment modes after printing and dyeing of bedding knitwear.

[0041] See also Figure 8-11In the embodiment of the present invention, the cleaning reflux mechanism 5 is composed of a Z-block 51, a connector 52, a first bevel gear 53, a second bevel gear 54, an impeller 55, a pump housing 56, a water intake pipe 57, a water delivery pipe 58, a water storage tank 59, a semi-cylinder 510, a drive block 511, and a torsion spring 512, wherein the Z-block 51 is welded to the top of the outer wall of one side of the baffle plate 41. The Z-block 51 can cooperate with the drive block 511, and the Z-block 51 is responsible for adjusting the inclination angle of the drive block 511. The connector 52 is fixedly connected to the outer wall of the bottom of the inner rod 37, the first bevel gear 53 is fixedly connected to the outer wall of the connector 52, and the second bevel gear 54 is meshed with the outer wall of the first bevel gear 53, and the impeller 55 is welded to the outer wall of one side of the second bevel gear 54. During the rotation of the inner rod 37, the connector 52, the first bevel gear 53 and the second bevel gear 54 will rotate together in sequence, thereby controlling the rotation of the impeller 55. The pump housing 56 is arranged outside the impeller 55, and the impeller 55 is rotatably connected to the inner wall of the pump housing 56. The two ends of the water intake pipe 57 are respectively fixedly mounted on the pump housing 56 and the inner wall of the tank body 2, and the water delivery pipe 58 is fixedly mounted on one side of the outer wall of the pump housing 56. As the impeller 55 rotates, the air pressure inside the pump housing 56 will change. Under the influence of the air pressure, the water intake pipe 57 can absorb a part of the purified sewage in the drain pipe 23 and deliver it to the water storage tank 59 through the water delivery pipe 58. The water storage tank 59 is fixedly connected to the outer wall of one end of the water delivery pipe 58, and the semi-cylinder 510 is rotatably connected to the inner wall of the water storage tank 59. In a sealed state, the semi-cylinder 510 will prevent the purified water from being discharged through the water storage tank 59. The driving block 511 is welded to the outer wall of one end of the semi-cylinder 510, and the torsion spring 512 is fixedly connected between the outer wall of the other end of the semi-cylinder 510 and the water storage tank 59. When the Z-shaped block 51 contacts the driving block 511 and adjusts the inclination angle of the driving block 511, water can be discharged from the water storage tank 59 from top to bottom. After the Z-shaped block 51 passes through the driving block 511, under the action of the torsion spring 512, the semi-cylinder 510 will reset and seal the water storage tank 59.

[0042] With the coordinated cooperation of the four gears inside the gear frame 31, the inner rod 37 can rotate along the center of the inner wall of the top frame 21 at a faster speed. Since the connecting piece 52 is fixed at the bottom of the stirring rod 371, during the rotation of the inner rod 37, the first bevel gear 53 can drive the second bevel gear 54 to rotate, thereby controlling the rotation of the impeller 55. Under the influence of the change in air pressure inside the pump casing 56, the water intake pipe 57 can absorb a part of the purified sewage in the drainage pipe 23 and send it to the water storage tank 59 through the water supply pipe 58. As the baffle plate 41 rotates, the Z-shaped block 51 can circulate and approach and contact the driving block 511 to control the inclination of the semi-cylinder 510, so that the permeable outer groove 6 and the permeable inner groove 7 can be on the same vertical plane, and then in the process of the baffle plate 41 moving to the bottom of the water storage tank 59, the water flow can flow out along the slot to clean the baffle plate 41, reducing the risk of the baffle plate 41 agglomerating and blocking the mesh holes, thereby increasing the service life of the baffle plate 41.

[0043] See also Figure 4 In the embodiment of the present invention, the inner rod 37 is composed of a stirring rod 371, a stirring blade 372 and an auger rod 373, wherein the stirring blade 372 is arranged inside the top frame 21 and the bottom bucket 22, and the auger rod 373 is arranged inside the drain pipe 23. The stirring blade 372 and the auger rod 373 rotate with the rotation of the stirring rod 371, and the stirring blade 372 is used to speed up the mixing speed between the sewage and the cleaning agent, and with the rotation of the auger rod 373, the purified sewage is forced to be discharged from the drain pipe 23.

[0044] See also Figure 6 In the embodiment of the present invention, the scraper 44 is composed of a long straight plate and a tail end plate, and the tail end plate is obliquely distributed at one end of the long straight plate. When the baffle plate 41 approaches the scraper 44, it will first contact the tail end plate and then control the sliding of the scraper 44. When the baffle plate 41 rotates to the side close to the scraper 44, it will first contact the tail end plate of the scraper 44. The tail end plate is squeezed and pushes the long straight plate of the scraper 44 to slide in the direction of the limit frame 43. The scraper 44 can further scrape off the scum attached to the surface of the baffle plate 41, thereby accelerating the scum processing speed.

[0045] See also Figure 10-11In the embodiment of the present invention, a water-permeable outer groove 6 is provided on the outer wall of the bottom of the water storage tank 59, and a water-permeable inner groove 7 is provided on the outer wall of one side of the semi-cylinder 510, wherein the water-permeable outer groove 6 and the water-permeable inner groove 7 are both used to discharge the purified sewage downward. When the belt is in operation, the water-permeable inner groove 7 and the water-permeable outer groove 6 are not in the same vertical plane. At this time, the semi-cylinder 510 will block the purified sewage from being discharged from the water-permeable outer groove 6 and is in a sealed state. When the Z-shaped block 51 contacts the driving block 511, the semi-cylinder 510 will rotate and adjust the position of the water-permeable inner groove 7, so that the water-permeable inner groove 7 and the water-permeable outer groove 6 are in the same vertical plane and are in a development state. The purified sewage can be discharged downward along the water-permeable inner groove 7 and the water-permeable outer groove 6 to clean the baffle plate 41.

[0046] See also Figure 1 In the embodiment of the present invention, a sewage pipe 8 and a cleaning agent pipe 9 are fixedly connected to the outer wall of one side of the frame 1, and the outer walls of one end of the sewage pipe 8 and the cleaning agent pipe 9 are both arranged on the top of the tank body 2, wherein the sewage pipe 8 is used to transport the wastewater after the printing and dyeing of the bed knitwear to the tank body 2, and the cleaning agent pipe 9 is used to put the cleaning agent to treat the sewage. The wastewater after the printing and dyeing of the bed knitwear can be transported to the tank body 2 through the sewage pipe 8 before treatment, and at the same time, the cleaning agent used to neutralize the sewage can be put into the tank body 2 through the cleaning agent pipe 9.

[0047] See also Figure 1 In the embodiment of the present invention, a drainage gap is provided on one side of the top frame 21 close to the limit frame 43, and a drainage trough plate 10 is welded on the inner wall of the drainage gap, wherein the drainage trough plate 10 is used to drain the scum after sewage purification. Since the lowest point of the drainage gap is lower than the height of the top frame 21, the scum will be discharged along the drainage gap with the push of the baffle plate 41, and then discharged along the inner wall of the drainage trough plate 10.

[0048] See also Figure 2 In the embodiment of the present invention, the top outer wall of the frame 1 is welded with symmetrically distributed support rods 11, and the gear frame 31 is fixedly connected between the two support rods 11. The support rods 11 are used to fix the gear frame 31 so that the gear frame 31 can be arranged at the top of the pool body 2.

[0049] See also Figure 2 In the embodiment of the present invention, a symmetrically distributed docking plate 12 is welded between the end of the water storage tank 59 and the gear frame 31. The docking plate 12 is used to fix the water storage tank 59 and the gear frame 31 together.

[0050] See also Figure 8In the embodiment of the present invention, the bottom of the outer wall of the drain pipe 23 is fixedly connected with a clamp 13, and the outer wall of one side of the pump housing 56 is fixedly connected to the outer wall of the clamp 13. The clamp 13 needs to be fixed to the bottom of the drain pipe 23 in advance, and then the pump housing 56 is fixed to the clamp 13 by welding or screwing, so as to prevent the pump housing 56 from falling off from one side of the drain pipe 23.

[0051] The working principle of the present invention is: first, the waste water after the printing and dyeing of the bedding knitwear is transported to the pool body 2 through the sewage pipe 8, and at the same time, the cleaning agent used to neutralize the sewage is put into the pool body 2 through the cleaning agent pipe 9, and then the servo motor 32 is started, and the gear column 33 is driven to rotate together by the servo motor 32, thereby driving the top gear 34 and the bottom gear 35 to rotate, thereby driving the inner rod traction gear 36 and the outer tube traction gear 38 to rotate, thereby driving the inner rod 37 and the outer tube 39 to rotate, wherein the inner rod 37 is responsible for stirring the sewage, and the outer tube 39 is used to install the corresponding slag discharge structure, and the stirring blade 372 and the auger rod 373 in the inner rod 37 will rotate with the rotation of the stirring rod 371, and the stirring blade 372 is used to accelerate the mixing speed between the sewage and the cleaning agent, and with the rotation of the auger rod 373, the purified sewage is forced to be discharged from the drain pipe 23;

[0052] When the outer pipe 39 rotates along the center of the inner wall of the top frame 21, the baffle plate 41 can rotate and intercept the scum floating on the water surface. As the baffle plate 41 continues to rotate, under the blocking effect of the scraper 44, the scraper 44 can scrape off the scum on the surface of the baffle plate 41 while continuously contacting the scraper 44. Under the joint action of the baffle plate 41 and the scraper 44, the scum will be discharged along the sewage discharge gap and then discharged along the inner wall of the sewage discharge trough plate 10. Afterwards, by utilizing the rebound effect of the spring coil spring 45, when the baffle plate 41 passes through the scraper 44, the scraper 44 can be reset to the initial position again;

[0053] At the same time, during the rotation of the inner rod 37, the first bevel gear 53 can drive the second bevel gear 54 to rotate, thereby controlling the rotation of the impeller 55. Under the influence of the change in air pressure inside the pump casing 56, the water intake pipe 57 can absorb a part of the purified sewage in the drainage pipe 23 and send it to the water storage tank 59 through the water delivery pipe 58. At this time, the water storage tank 59 is in a sealed state. As the baffle plate 41 rotates, the Z-shaped block 51 can circulate close to and contact the driving block 511 to control the inclination of the semi-cylinder 510, so that the permeable outer groove 6 and the permeable inner groove 7 can be on the same vertical plane. In the process of the baffle plate 41 moving to the bottom of the water storage tank 59, the water flow can flow out from top to bottom along the slot to clean the baffle plate 41. When the baffle plate 41 passes through the water storage tank 59, the water storage tank 59 will be sealed again, and the cycle will repeat.

[0054] The above are only preferred specific implementation modes of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solutions and inventive concepts of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
