Description

Technical Field

[0001] This utility model relates to the field of magnetic coagulation defluorination, specifically a magnetic coagulation deep defluorination device for semiconductor wastewater. Background Technology

[0002] Magnetic mixing for deep fluoride removal from wastewater is a highly efficient and deep fluoride removal technology. The role of magnetic powder: the density of magnetic powder is generally 4.5-5.0 g / cm³. 3 Adding magnetic powder to the conventional coagulation and sedimentation process allows it to bind with the coagulated flocs, significantly increasing floc density and accelerating sedimentation. Simultaneously, the surface-treated magnetic powder exhibits both physical and electrostatic adsorption properties, further removing pollutants such as fluoride ions from the water.

[0003] In existing technologies, coagulants and flocculants containing magnetic powder are generally directly thrown into the coagulation reaction tank from one point by manual or mechanical means. Then, they are stirred manually or mechanically to achieve uniform distribution of the coagulants and flocculants containing magnetic powder in the coagulation reaction tank. This method has room for further improvement in efficiency. Utility Model Content

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figures 1-4 In this embodiment of the present invention, a semiconductor wastewater magnetic coagulation deep defluorination device includes a coagulation reaction tank 1. A drive mechanism is installed on both sides of the end plate of the coagulation reaction tank 1. A moving block 5 is threadedly connected to the drive mechanism. A connecting frame 6 is fixedly installed on the top of the moving block 5. A material hopper 13 is fixedly installed between the two connecting frames 6. The material hopper 13 has a hollow structure, and both the top and bottom of the material hopper 13 have an open structure. A uniform feeding mechanism is installed at the discharge nozzle position of the material hopper 13 and at the top of the coagulation reaction tank 1.

[0019] In this embodiment: First, after the wastewater is transported to the coagulation reaction tank 1, flocculant and coagulant containing magnetic powder are loaded into the reaction chamber 13. Then, by starting the drive mechanism, the drive mechanism drives two moving blocks 5 to slide axially along the length direction of the coagulation reaction tank 1. The two sliding moving blocks 5 drive the connecting frame 6 connected to them to move synchronously. The two moving connecting frames 6 can drive the material chamber 13 to move simultaneously. The moving material chamber drives the uniform feeding mechanism to rotate. At this time, the coagulant and flocculant containing magnetic powder in the material chamber 13 are evenly sprinkled into the interior of the coagulation reaction tank 1 to carry out the defluorination operation.

[0020] This design scheme has the effect of evenly distributing flocculants and coagulants containing magnetic powder, avoiding the problem of poor local defluorination effect caused by uneven distribution of magnetic powder in the coagulation reaction tank 1.

[0021] Please refer to this carefully. Figure 1 and Figure 3 The driving mechanism includes a screw 4 rotatably mounted between two support ears 2. The screw 4 is threadedly connected to the moving block 5. The coagulation reaction tank 1 is equipped with a forward and reverse motor 9 via a bracket. The output end of the forward and reverse motor 9 is coaxially and fixedly connected to one end of a screw 4. The driving mechanism includes a pulley 7 fixedly mounted on one end of the two screws 4. The two pulleys 7 are connected by a transmission belt 8. A guide rod 3 is fixedly mounted between the two support ears 2. The moving block 5 has a round hole that is slidably connected to the guide rod 3.

[0022] In this embodiment: by starting the forward and reverse motor 9, the forward and reverse motor 9 drives the screw 4 connected to it to rotate through the coupling. The screw 4 drives the pulley 7 at its other end to rotate. The pulley 7 then drives another pulley 7 to rotate synchronously and in the same direction through the transmission belt 8. The other pulley 7 drives the other screw 4 connected to it to rotate. At this time, the two screws 4 rotate simultaneously, in the same direction and at the same speed. The two rotating screws 4 can drive the moving block 5 to move axially.

[0023] Please refer to this carefully. Figure 3 and Figure 4The uniform feeding mechanism includes a rack 10 fixedly installed at the top of the coagulation reaction tank 1. The rack 10 is distributed along the length of the screw 4. Gears 11 mesh with the rack 10. A rotating shaft 12 that penetrates into the material bin 13 is welded to one end of the two gears 11 that are close to each other. The rotating shaft 12 and the material bin 13 are rotatably connected by bearings. The uniform feeding mechanism also includes a rotating roller 14 rotatably installed at the feeding nozzle of the material bin 13. The rotating roller 14 is fixedly installed on the outer periphery of the rotating shaft 12. A metering groove 15 is equidistantly formed on the outer periphery of the rotating roller 14. The vertical cross section of the metering groove 15 is semi-circular.

[0024] In this embodiment: During the operation of the drive mechanism, the moving block 5 drives the material bin 13 to move synchronously through the connecting frame 6. When the material bin 13 moves, it drives the gear 11 to move synchronously through the rotating shaft 12. Since the gear 11 and the rack 10 mesh and the rack 10 cannot rotate, the moving gear 11 will rotate under the limitation of the rack 10. Therefore, the gear 11 rotates while moving axially. The rotating gear 11 drives the rotating roller 14 to rotate through the rotating shaft 12. The rotating roller 14 drives the multiple metering grooves 15 on its outer periphery to rotate synchronously. When the metering groove 15 is at the top, the coagulant and flocculant containing magnetic powder in the material bin 13 will enter the metering groove 15. During the process of the metering groove 15 rotating from the top to the bottom, the flocculant and coagulant in the metering groove 15 fall downward into the coagulation reaction tank 1, so as to achieve the uniform distribution of the flocculant and coagulant containing magnetic powder into the coagulation reaction tank 1, avoiding the problem of incomplete defluorination caused by uneven distribution.

[0025] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
