Description

Technical Field

[0001] This utility model relates to the field of flocculation and sedimentation technology, specifically to a flocculation and sedimentation device for high-concentration turbid circulating water recovery. Background Technology

[0002] In industrial production and wastewater treatment, the treatment of high-concentration turbid circulating water is a critical and challenging task. High-concentration turbid circulating water typically contains large amounts of suspended particles, impurities, and pollutants. Direct discharge or reuse not only causes serious environmental pollution but also affects the normal operation of subsequent production equipment and product quality. Therefore, effectively treating high-concentration turbid circulating water to achieve solid-liquid separation, obtain relatively clear supernatant water, and properly treat sediment is of significant practical importance. Currently, one common method for treating turbid circulating water is to introduce it into a sedimentation chamber and add flocculants to coagulate suspended particles into larger flocs, followed by natural sedimentation to achieve solid-liquid separation. After sedimentation, an external pumping device removes the relatively clear supernatant water for subsequent reuse or discharge; while the sediment accumulated at the bottom of the sedimentation chamber is discharged through a drain pipe.

[0003] Existing devices have some drawbacks during use, such as: the bottom wall of the sedimentation box is too flat and lacks an effective tilt angle or flow guiding structure. Under the action of gravity, the sediment is difficult to concentrate in a specific area and tends to accumulate in a large area at the bottom. The wide distribution of sediment increases the difficulty of cleaning. Utility Model Content

[0004] The purpose of this invention is to provide a flocculation and sedimentation device for high-concentration turbid circulating water recovery, which solves the problem of widely distributed sediments, increasing the difficulty of removal.

[0005] This utility model provides the following technical solution: a flocculation sedimentation device for high-concentration turbid circulating water recovery, including a sedimentation frame, an inclined block fixedly installed on the bottom wall of the sedimentation frame, a mixing treatment component provided on one side of the upper end face of the sedimentation frame, a moving component provided on the other side of the upper end face of the sedimentation frame, a cleaning component provided on the moving component, the moving component and the cleaning component working together, and a discharge pipe fixedly connected to one side of the lower end face of the sedimentation frame.

[0014] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Example

[0015] like Figures 1-4 As shown, this utility model provides a technical solution: a flocculation and sedimentation device for high-concentration turbid circulating water recovery, including a sedimentation frame 1, an inclined block 11 fixedly installed on the bottom wall of the sedimentation frame 1, a mixing treatment component 2 provided on one side of the upper end face of the sedimentation frame 1, a moving component 3 provided on the other side of the upper end face of the sedimentation frame 1, a cleaning component 4 provided on the moving component 3, the moving component 3 and the cleaning component 4 working together, and a discharge pipe 12 fixedly connected to one side of the lower end face of the sedimentation frame 1. In specific use, high-concentration turbid circulating water is introduced into the mixing treatment component 2, so that the high-concentration turbid circulating water and flocculant are fully mixed. During the stirring process, the flocculant and the suspended particles in the turbid circulating water undergo adsorption, bridging and other effects to form larger flocs. Then the mixed liquid is introduced into the sedimentation frame 1 for sedimentation. After sedimentation, the upper water is pumped out by an external water pumping device, and the sediment accumulated on the inclined block 11 is discharged through the discharge pipe 12. The moving component 3 and the cleaning component 4 work together to quickly clean the inside of the sedimentation frame.

[0016] In one embodiment of this invention, the mixing and treatment component 2 includes a bracket 21 fixedly installed on the upper surface of the sedimentation frame 1. A treatment tank 22 is fixedly installed inside the bracket 21. An installation plate 23 is fixedly installed on the upper surface of the treatment tank 22. A drive motor 24 is fixedly installed on the installation plate 23. A drive rod 25 is fixedly installed at the output end of the drive motor 24. Multiple stirring rods 26 are fixedly sleeved on the outer wall of the drive rod 25. A discharge pipe 27 is fixedly connected to the bottom end of the treatment tank 22. The bottom end of the discharge pipe 27 vertically passes through the top wall of the sedimentation frame 1 and extends to the inner side of the sedimentation frame 1. A feed pipe 28 is fixedly connected to the top end of the treatment tank 22. In actual use, high-concentration turbid circulating water and flocculant are introduced into the treatment tank 22 in a certain proportion through the feed pipe 28. The drive motor 24 is started, and the drive rod 25 drives the stirring rods 26 to rotate, stirring the high-concentration turbid circulating water and flocculant in the treatment tank 22. After stirring, the valve of the discharge pipe 27 is opened, and the mixed liquid is introduced into the sedimentation frame 1 for sedimentation.

[0017] As one embodiment of this invention, the moving component 3 includes fixed plates 31 symmetrically fixed to the upper surface of the sedimentation frame 1. A threaded rod 32 is rotatably connected between the two fixed plates 31. A servo motor 33 is fixedly installed at one end of the threaded rod 32. A placement plate 34 is fixedly installed at the lower end of the servo motor 33. One end of the placement plate 34 is fixed to the side wall of one of the fixed plates 31. A movable sleeve 35 is fixedly sleeved on the outer wall of the threaded rod 32. A limiting slide rod 36 is inserted into the movable sleeve 35. Both ends of the limiting slide rod 36 are fixed to the side wall of the corresponding fixed plate 31. The movable sleeve 35 slides on the outer wall of the limiting slide rod 36. In actual use, when it is necessary to clean the inside of the sedimentation frame 1, the servo motor 33 is started. The servo motor 33 starts to rotate, driving the threaded rod 32 to rotate. Since the movable sleeve 35 is fixedly sleeved on the outer wall of the threaded rod 32 and is limited and guided by the limiting slide rod 36, the movable sleeve 35 will move linearly along the axis of the threaded rod 32 as the threaded rod 32 rotates. The direction of movement of the movable sleeve 35 depends on the rotation direction of the servo motor 33. By controlling the forward and reverse rotation of the servo motor 33, the movable sleeve 35 can reciprocate between the two fixed plates 31. During the movement, the movable sleeve 35 will drive the cleaning component 4 connected to it to move together. During the movement, the cleaning component 4 will perform a cleaning operation on the inside of the sedimentation frame 1 to achieve a comprehensive cleaning of the inside of the sedimentation frame 1.

[0018] In one embodiment of this invention, the cleaning component 4 includes vertical plates 41 symmetrically fixed to the side walls of the movable sleeve 35. A fixing post 42 is fixedly connected between the two vertical plates 41. A collar 43 is sleeved on the outer wall of the fixing post 42, and a spray head 44 is fixedly connected to the outer wall of the collar 43. A water inlet end of the spray head 44 is connected to a water guide pipe 45, which is connected to an external water supply unit. In actual use, when it is necessary to clean the inside of the sedimentation frame 1, the water guide pipe 45 is... Once connected to an external water supply unit, which can be a water pump or a tap water pipe, capable of providing sufficient pressure and flow of water, the external water supply unit begins supplying water. The water is delivered to the spray head 44 through the water guide pipe 45. The spray head 44 sprays water at a certain pressure and angle onto the inner wall and bottom of the sedimentation frame 1 to rinse away residual sediment. During movement, the spray direction of the spray head 44 can be changed by adjusting the position or angle of the collar 43 on the fixed column 42, thereby achieving a thorough cleaning of the interior of the sedimentation frame 1. It should be noted that the collar 43 is made of plastic and is an open-type ring. The collar 43 can be removed from the fixed column 42 by hand.

[0019] As one embodiment of this invention, pads 101 are fixedly connected to the four corners of the lower end face of the sedimentation frame 1, and the pads 101 provide installation and accommodating space for the discharge pipe 12.

[0020] As one embodiment of this example, a sealing cap 121 is threaded onto the bottom end of the discharge pipe 12. The sealing cap 121 is tightly fitted onto the bottom end of the discharge pipe 12 to prevent the liquid or sediment in the sedimentation frame 1 from leaking out, maintain the sealed environment inside the sedimentation frame 1, and ensure the smooth progress of sedimentation and other processes.

[0021] Working principle: In use, high-concentration turbid circulating water and flocculant are introduced into treatment tank 22. Then, drive motor 24 is started, and drive rod 25 drives stirring rod 26 to rotate, stirring the high-concentration turbid circulating water and flocculant in treatment tank 22. During the stirring process, the high-concentration turbid circulating water and flocculant are fully mixed. The flocculant and suspended particles in the turbid circulating water undergo adsorption and bridging to form larger flocs. After stirring, the valve of discharge pipe 27 is opened, and the mixed liquid is introduced into sedimentation frame 1. These flocs gradually sink and settle under gravity. After sedimentation, the upper layer of water is pumped out by an external pumping device, while the sediment accumulated on the inclined block 11 is discharged through discharge pipe 12. When it is necessary to clean the inside of sedimentation frame 1, the sedimentation process is completed. During cleaning, the servo motor 33 is started and begins to rotate, driving the threaded rod 32 to rotate. Since the movable sleeve 35 is fixedly sleeved on the outer wall of the threaded rod 32 and is limited and guided by the limiting slide rod 36, the movable sleeve 35 will move linearly along the axis of the threaded rod 32 as the threaded rod 32 rotates. The direction of movement of the movable sleeve 35 depends on the rotation direction of the servo motor 33. By controlling the forward and reverse rotation of the servo motor 33, the movable sleeve 35 can reciprocate between the two fixed plates 31. During the movement, the movable sleeve 35 will drive the spray head 44 to spray water at a certain pressure and angle onto the inner wall and bottom of the sedimentation frame 1 to rinse the residual sediment, and the wastewater is discharged through the discharge pipe 12.
