[0029] like Figures 1 to 7As shown, the present invention provides a wastewater treatment equipment for polyvinyl pyrrolidone production, comprising a sewage treatment tank 1, a sedimentation tank 2, a transmission belt 4, a pulley 5 and a servo motor 7. A mixing tank 10 is detachably connected on the input direction of the sedimentation tank 2, a water storage tank 8 is detachably connected on the input direction of the mixing tank 10, a reagent tank 9 is detachably connected between the water storage tank 8 and the mixing tank 10, a plug 18 is slidably connected to the output end of the reagent tank 9, a plug 23 is overlapped on the output port of the plug 18, a paddle plate 26 is overlapped on the input end of the paddle plate 23, an input end of the paddle plate 26 is detachably connected to the servo motor 7, an output end of the paddle plate 26 is connected to a linkage rod 12, a worm 13 is welded on the linkage rod 12, a stirring frame 25 is provided in the output direction of the worm 13, the stirring frame 25 is rotatably connected to the inclined plate 11, and the inclined plate 11 is detachably connected in the mixing tank 10. By installing a mixing tank 10 on the input direction of the sedimentation tank 2, the wastewater in the mixing tank 10 can enter the sedimentation tank 2 through the opening 3. A water storage tank 8 is installed on the mixing tank 10. The wastewater in the water storage tank 8 will enter the mixing tank 10 through the flow port 6, and the flow rate of the wastewater can be controlled. A reagent tank 9 is installed on the output direction of the flow port 6, and a top plate 21 is arranged below the reagent tank 9. When the servo motor 7 drives the paddle plate 26 to rotate, the paddle plate 26 will first intercept the wastewater and then push the top plate 21, and the flow rate of the wastewater will be reduced. When the top plate 21 is pushed, the reagent is discharged onto the paddle plate 26, and as the paddle plate 26 rotates, it finally moves to the stirring frame 25, so that it is stirred by the stirring frame 25 and quickly mixed with the wastewater. The equipment is simple to set, low in cost, and easy to operate. The staff only needs to place the reagent in the reagent tank 9, thereby reducing the labor intensity of the staff.

[0030] A through-port 3 is provided at the connection between the mixing tank 10 and the sedimentation tank 2. The through-port 3 is respectively located at the two ends of the sedimentation tank 2. The through-port 3 is arranged in a rectangular shape as a whole. The through-port 3 is located in the output direction of the inclined plate 11. One end of the inclined plate 11 is detachably connected to the side wall of the mixing tank 10, and the other end of the inclined plate 11 is detachably connected to the bottom of the mixing tank 10. The mixing tank 10 and the sedimentation tank 2 can be connected through the through-port 3, and the wastewater of the mixed reagent will eventually enter the sedimentation tank 2 through the through-port 3, thereby realizing the sedimentation treatment of the wastewater.

[0031] The linkage rod 12 is arranged along the length of the inclined plate 11. The linkage rod 12 is located in the space surrounded by the inclined plate 11 and the mixing tank 10. One end of the linkage rod 12 is located outside the mixing tank 10. The end of the linkage rod 12 outside the mixing tank 10 is detachably connected with a pulley 5, on which a transmission belt 4 is sleeved, and the other end of the transmission belt 4 is sleeved on the pulley 5 of the paddle plate 26.

The transmission belt 4 is sleeved between the two pulleys 5, and the servo motor 7 can drive the linkage rod 12 while driving the paddle plate 26, and the linkage rod 12 can drive the worm wheel 14 to rotate.

[0032] In practice, by installing a mixing tank 10 on the sedimentation tank 2, a water storage tank 8 is installed on the mixing tank 10, and wastewater can first flow into the water storage tank 8. When the water surface of the wastewater reaches the flow port 6, it will enter the mixing tank 10 through the flow port 6. When passing through the flow port 6, the amount of wastewater can be limited, and the wastewater can pass through the inclined plate 11 slowly. When the servo motor 7 is started, the servo motor 7 can drive the paddle 26 to rotate. The edge of the paddle 26 overlaps the side wall of the mixing tank 10. The paddle 26 is located in the output direction of the flow port 6. When the paddle 26 contacts the side wall of the mixing tank 10, it can cut off the water flow, thereby reducing the flow speed of the water body. The paddle 26 will push the top during the rotation process. The top plate 21 is moved. After being pushed by the paddle plate 26, the top plate 21 will drive the blocking plate 23 away from the cannula 18, and the cannula 18 will not be blocked. The medicine in the cannula 18 can fall onto the paddle plate 26, and then be driven onto the inclined plate 11, so as to be mixed with the wastewater. The inclined plate 11 is equipped with a stirring frame 25, and the stirring frame 25 will be driven by the servo motor 7 to rotate. When the medicine falls on the inclined plate 11, it will be stirred by the stirring frame 25 and mixed with the wastewater. The amount of water flowing on each side is small, so as to achieve full mixing of the medicine and the wastewater. In the whole process, the staff only needs to store the medicine in the medicine tank 9. The equipment has a simple dosing method, sensitive response and low cost, so as to meet the production needs.

[0033] A flow port 6 is provided at the connection between the mixing tank 10 and the water storage tank 8. The flow port 6 is located above the inclined plate 11. A stirring rack 25 is connected to the inclined plate 11 in the output direction of the flow port 6. The stirring rack 25 is arranged along the length of the inclined plate 11. Each stirring rack 25 is provided with a corresponding rotating rod 15. The flow port 6 can realize the flow of wastewater, and the wastewater can enter the mixing tank 10 through the water storage tank 8, thereby avoiding a large amount of wastewater flowing in at one time, reducing the flow volume of wastewater to facilitate mixing with the medicine, so that the medicine can be mixed with the components.

[0034] The rotating rod 15 is connected through the inclined plate 11, and the rotating rod 15 on the other side of the inclined plate 11 is detachably connected with a worm wheel 14, which is meshedly connected with the corresponding worm 13. The reagent tank 9 above the stirring frame 25 is detachably connected with a bottom tank 16, and the bottom tank 16 connected with the reagent tank 9 is arranged in a V shape as a whole. The stirring frame 25 can be carried by the inclined plate 11, and the stirring frame 25 can stir the wastewater flowing down, thereby facilitating the full stirring of the wastewater.

[0035] A corresponding long tube 17 is welded on the output end of the bottom groove 16, and the long tube 17 faces the bottom of the medicine groove 9. A corresponding insertion tube 18 is inserted into the long tube 17. By installing the long tube 17 on the bottom groove 16, the long tube 17 can enter the medicine. When the insertion tube 18 is inserted into the long tube 17, the insertion tube 18 will communicate with the long tube 17, thereby realizing the flow of the medicine.

[0036] The diameter of the insert tube 18 is the same as the inner diameter of the long tube 17. The insert tube 18 is connected to the medicine tank 9 through the insert tube 18. A corresponding partition 19 is welded on the insert tube 18. The partition 19 is located on the outer wall of the insert tube 18 and overlaps the bottom of the medicine tank 9. By installing the partition 19 on the insert tube 18, the partition 19 can overlap the bottom of the medicine tank 9, thereby preventing the insert tube 18 from being separated from the long tube 17. The insert tube 18 is movably connected to the medicine tank 9, and the insert tube 18 can move in the long tube 17. When the insert tube 18 moves in the long tube 17, it can stir the medicine to prevent the medicine from agglomerating, thereby facilitating the flow of the medicine.

[0037] A bracket 20 is welded to the outer bottom of the medicine tank 9, and the bracket 20 is arranged vertically on the medicine tank 9. A corresponding connecting frame 22 is rotatably connected to the bracket 20. By installing the bracket 20 on the medicine tank 9, the connecting frame 22 can be installed on the bracket 20, and the connecting frame 22 can be rotated on the bracket 20.

[0038] The connecting frame 22 is welded to the corresponding top plate 21, and the top plate 21 and the connecting frame 22 are in a V shape as a whole. A blocking plate 23 is welded at the connection between the top plate 21 and the connecting frame 22, and the blocking plate 23 corresponds to the output port of the cannula 18. When the top plate 21 and the connecting frame 22 are connected, the top plate 21 can rotate, thereby driving the blocking plate 23 away from the cannula 18 and closer to the cannula 18.

[0039] The blocking plate 23 is overlapped on the corresponding port of the cannula 18, and the edge of the top plate 21 is detachably connected with a return spring 24, and the other end of the return spring 24 is detachably connected to the medicine tank 9. The return spring 24 can be used to pull the top plate 21, and the top plate 21 can be reset by the return spring 24 after it is not pushed.

[0040] In practice, by installing the bracket 20 on the medicine tank 9, the connecting frame 22 can be installed on the bracket 20, and the top plate 21 can be rotated on the bracket 20 through the connecting frame 22. A blocking plate 23 is installed between the connecting frame 22 and the top plate 21. When the top plate 21 is pushed by the paddle plate 26, the blocking plate 23 will be driven away from the cannula 18. When the cannula 18 is not blocked, the medicine will be injected. When the paddle plate 26 is away from the top plate 21, the top plate 21 will be pulled by the reset spring 24 and reset, and the blocking plate 23 can be inserted again. If the tube 18 is blocked, the medicine cannot be delivered, thereby achieving control over the amount of medicine delivered and avoiding waste of the medicine. The insert tube 18 is plugged into the long tube 17 of the bottom groove 16, and the insert tube 18 is movably installed in the long tube 17. When the plug plate 23 blocks the insert tube 18, it will drive the insert tube 18 to move slightly, and the insert tube 18 will move a certain distance into the long tube 17. When the insert tube 18 moves in the long tube 17, it can stir the medicine, thereby loosening the medicine and preventing it from agglomerating in the long tube 17 and being unable to be discharged.

[0041] The working principle of the present invention is as follows: by installing a mixing tank 10 on the sedimentation tank 2, a water storage tank 8 is installed on the mixing tank 10, and wastewater can first flow into the water storage tank 8. When the water surface of the wastewater reaches the flow port 6, it will enter the mixing tank 10 through the flow port 6. When passing through the flow port 6, the amount of wastewater can be limited, and the wastewater can pass through the inclined plate 11 at a slow speed. When the servo motor 7 is started, the servo motor 7 can drive the paddle 26 to rotate. The edge position of the paddle 26 overlaps the side wall of the mixing tank 10. The paddle 26 is located in the output direction of the flow port 6. The paddle 26 contacts the side wall of the mixing tank 10. When the paddle plate 26 rotates, the top plate 21 is pushed by the paddle plate 26. After the top plate 21 is pushed by the paddle plate 26, the blocking plate 23 is driven away from the insertion tube 18, and the insertion tube 18 is not blocked. The medicine in the insertion tube 18 can fall on the paddle plate 26, and then be driven to the inclined plate 11, so as to be mixed with the wastewater. The inclined plate 11 is equipped with a stirring frame 25, and the stirring frame 25 is driven by the servo motor 7 to rotate. When the medicine falls on the inclined plate 11, it is stirred by the stirring frame 25 and mixed with the wastewater. The amount of water flowing on each side is small, so as to achieve The medicine and the wastewater are fully mixed. During the whole process, the staff only needs to store the medicine in the medicine tank 9. The equipment has a simple dosing method, is sensitive to reaction, and has low cost, so as to meet the production needs. By installing the bracket 20 on the medicine tank 9, the connecting frame 22 can be installed on the bracket 20, and the top plate 21 can be rotated on the bracket 20 through the connecting frame 22. A blocking plate 23 is installed between the connecting frame 22 and the top plate 21. When the top plate 21 is pushed by the paddle plate 26, the blocking plate 23 will be driven away from the cannula 18. When the cannula 18 is not blocked, the medicine will be dosed. When the paddle plate 26 is away from the top plate 21, the top plate 21 will be pulled by the reset spring 24 and reset, and the blocking plate 23 can block the cannula 18 again, and the medicine cannot be delivered, thereby realizing the control of the amount of medicine delivered and avoiding the waste of medicine. The cannula 18 is inserted into the long tube 17 of the bottom groove 16, and the cannula 18 is movably installed in the long tube 17. When the blocking plate 23 blocks the cannula 18, it will drive the cannula 18 to move slightly, and the cannula 18 will move a certain distance into the long tube 17. When the cannula 18 moves in the long tube 17, it can stir the medicine, thereby loosening the medicine and preventing it from agglomerating in the long tube 17 and being unable to be discharged.
