Description

Technical Field

[0001] The utility model relates to a device for separating clear water from sewage, specifically a device for separating clear water from sewage in dyeing wastewater, and belongs to the technical field of dyeing wastewater treatment. Background Technique

[0002] Dyeing wastewater is also known as printing and dyeing wastewater. With the development of the textile printing and dyeing industry, the amount of printing and dyeing wastewater generated is increasing year by year, and the impact on the environment is also growing. With the continuous development of technology, the research and development achievements in treating printing and dyeing industrial wastewater are constantly being transformed and applied. Textile printing and dyeing wastewater has the characteristics of large water volume, high content of organic pollutants, high alkalinity, and large water quality changes, and belongs to one of the industrial wastewaters that are relatively difficult to treat.

[0003] A high-efficiency dyeing wastewater treatment device disclosed in the Chinese Patent Application Publication Specification CN113354153A includes a base, a sedimentation chamber, a control panel, an exhaust pipe, and an acid-base neutralization chamber. An acid-base neutralization chamber is arranged on one side of the top of the base, a water pump is arranged at the center of the top of the base, and a sedimentation chamber is arranged on the other side of the top of the base. This device not only realizes the mixing and stirring of wastewater and acid-base solution, discharges the waste gas after filtration and purification, but also performs sedimentation treatment on some residual dyes and impurities in the wastewater.

[0004] The above patent realizes the mixing and stirring of wastewater and acid-base solution during use, discharges the waste gas after filtration and purification, and performs sedimentation treatment on some residual dyes and impurities in the wastewater. However, this device still has some problems: the acid-base neutralization chamber and the sedimentation chamber are placed separately, increasing the floor area. There is no stirring device in the sedimentation chamber. If the precipitant is not stirred after being put into the sedimentation chamber, it will lead to a decrease in sedimentation efficiency, increase the time required for sedimentation, and thus reduce the overall wastewater treatment efficiency. At the same time, its cleaning effect on the sediment after sedimentation treatment of the wastewater is poor, affecting the overall treatment efficiency of the wastewater. Content of the Utility Model

[0028] Please refer particularly to Figure 1 、 Figure 2 and Figure 3 。 The stirring device 4 includes two groups of stirring rods 401 fixed to the outer surface of the rotating rod 3. The two groups of stirring rods 401 are arranged staggeredly, and each group of stirring rods 401 is arranged in a circular pattern around the rotating rod 3. The rotation of the rotating rod 3 can drive the stirring rods 401 to rotate. By stirring with the stirring rods 401, the mixing of the medicine and the sewage is accelerated.

The other end of each support rod 402 is rotatably connected to a turntable 403. Each turntable 403 is in contact with the inner wall of the conical diversion pool 2. A sleeve 404 is fixed to the bottom surface of each turntable 403. The sleeve 404 is sleeved on the support rod 402. An auger 405 is fixed to the outer surface of the sleeve 404. During the process of driving the turntable 403 to rotate by the rotation of the rotating rod 3, the turntable 403 rotates on its own axis. By the rotation of the turntable 403, the sleeve 404 is driven to rotate, and then the auger 405 is driven to rotate.

[0029] Please refer particularly to Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 and Figure 6 。 The conversion device 6 includes a baffle 601 fixed to the top end of the diversion pipe 5. An opening is provided on the upper surface of the baffle 601. A rotating cylinder 602 is rotatably connected to the inner wall of the diversion pipe 5. Two inlets 603 are provided on the upper surface of the rotating cylinder 602, and an outlet 604 is provided on the bottom surface of the rotating cylinder 602. The rotating rod 3 passes through the rotating cylinder 602. A plurality of partition plates 605 arranged in a circular pattern are fixed to the outer surface of the rotating rod 3. By the rotation of the rotating rod 3, the partition plates 605 inside the rotating cylinder 602 are driven to rotate. A first motor 9 is arranged on the bottom surface of the diversion pipe 5. The output end of the first motor 9 passes through the diversion pipe 5 and is fixed to the rotating cylinder 602. By the first motor 9, the rotating cylinder 602 can be driven to rotate.

[0030] Please refer particularly to Figure 1 、 Figure 2 and Figure 4 。 A top plate 10 is fixed to the upper surface of the sedimentation tank 1. A feed inlet 11 is provided on the upper surface of the top plate 10. A second motor 12 is installed on the upper surface of the top plate 10. The output end of the second motor 12 is fixed to the rotating rod 3. Through the feed inlet 11, sewage and treatment medicine can be discharged into the sedimentation tank 1. A push plate 13 is arranged above the baffle 601. The push plate 13 is fixed to the rotating rod 3. By the rotation of the rotating rod 3, the push plate 13 can be driven to rotate. The sediment is pushed into the opening of the baffle 601 by the push plate 13.

[0031] Working principle: To maintain the overall stability, support seats made of cast-in-place concrete are fixed to the sedimentation tank 1 and the conical diversion tank 2. First, sewage and medicine are added into the sedimentation tank 1 through the feed inlet 11. The second motor 12 is started through the control device. The output end of the second motor 12 drives the rotating rod 3 to rotate. The rotation of the rotating rod 3 drives the stirring rod 401 to rotate. The stirring rod 401 stirs the sewage in the sedimentation tank 1 and the conical diversion tank 2. At the same time, the rotation of the rotating rod 3 drives the support rod 402 to rotate. The rotation of the support rod 402 drives the turntable 403 to rotate. Due to the contact between the turntable 403 and the conical diversion tank 2, the turntable 403 rotates around the rotating rod 3 while rotating on its own axis. The self-rotation of the turntable 403 drives the sleeve 404 to rotate. The rotation of the sleeve 404 drives the auger 405 to rotate. The rotation of the auger 405 drives the sewage to move rapidly upward along the axis of the auger 405. The water flow falls after touching the inner wall of the sedimentation tank 1, thereby forming a vortex. Combined with the rotation and stirring of the support rod 402, the mixing of sewage and medicine is made more sufficient, solving the problem that the sedimentation time of the common dyeing wastewater treatment device in the prior art is relatively long, which affects the operation efficiency.

[0032] When the medicine and sewage react sufficiently to form precipitates, the second motor 12 is controlled by the control device to reverse and rotate slowly. The output end of the second motor 12 drives the rotating rod 3 to reverse. At this time, the auger 405 drives the precipitates to move downward along the axis. At the same time, the first motor 9 is started through the control device. The output end of the first motor 9 drives the rotating cylinder 602 to rotate. The rotation of the rotating cylinder 602 makes the inlet 603 coincide with the opening, and at the same time the outlet 604 is communicated with the sewage discharge pipe 7. At this time, the precipitates enter the rotating cylinder 602 through the inlet 603 and are transferred from the outlet 604 to the sewage discharge pipe 7 and discharged under the drive of the push plate 13. When it is detected by an external detection device that the sewage discharge pipe 7 no longer discharges precipitates, the output end of the first motor 9 drives the rotating cylinder 602 to rotate. The rotation of the rotating cylinder 602 makes the inlet 603 coincide with the opening, and at the same time the outlet 604 is communicated with the drain pipe 8. At this time, the clear water can be transferred to the drain pipe 8 through the rotating cylinder 602 and discharged, completing the separation of cleaning and sewage, and solving the problem that the common treatment device has a poor cleaning effect on precipitates.
