Description

Technical Field

[0001] This utility model belongs to the field of wastewater treatment technology, and in particular to a stirring device for a coagulation reaction tank. Background Technology

[0002] Wastewater treatment is the process of removing pollutants from urban wastewater, mainly including domestic sewage and some industrial wastewater. It uses physical, chemical, and biological processes to remove pollutants. Therefore, it is necessary to use a coagulation reactor to add chemicals to the wastewater and mix it to achieve a coagulation reaction. However, most of the mixing devices in current coagulation reactors mix the chemicals after they are introduced into the coagulation reactor. Because the chemicals are injected into the reactor at a single point, this mixing method requires a long time of mixing to fully mix the chemicals with the wastewater, which greatly reduces the mixing effect of the chemicals.

[0003] A search revealed a Chinese patent document (authorization announcement number CN220098700U) concerning a coagulation reaction tank with a stable and efficient agitator structure, belonging to the field of wastewater treatment technology. The device includes an installation plate, with a wastewater tank fixedly connected to its upper surface. A fixed frame is fixedly connected to the upper surface of the wastewater tank, and a first motor is fixedly connected inside the fixed frame. The output shaft of the first motor is fixedly connected to a first rotating shaft. While the above device achieves thorough mixing of different wastewater layers by adjusting the position of the agitator blades, in practice, the agitator still needs to be introduced into the reaction tank through a single point. Therefore, prolonged agitation is required to ensure complete mixing of the agitator and wastewater. Thus, a coagulation reaction tank agitator device is urgently needed to solve this problem. Utility Model Content

[0004] The purpose of this invention is to provide a stirring device for a coagulation reaction tank to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a coagulation reaction tank stirring device, comprising a base plate for installing the coagulation reaction tank and multiple stirring pipes for stirring the coagulation reaction tank, wherein a reaction cylinder is fixedly installed on the top surface of the base plate, and arc-shaped plates are symmetrically fixedly installed on the upper side wall of the reaction cylinder, and mounting plates are mounted on the top surfaces of the two arc-shaped plates.

[0006] A motor is fixedly mounted on the top surface of the mounting plate. A rotating tube is fixedly mounted at the end of the output shaft of the motor and extends into the interior of the reaction cylinder. Multiple stirring tubes are connected and installed on the side wall of the rotating tube, and multiple nozzles are connected and installed on the side wall of the stirring tube.

[0007] A sleeve is rotatably installed on the side wall of the rotating tube, and an infusion tube is connected to the side wall of the sleeve. The side wall of the rotating tube has multiple inlet holes, and the inlet holes are located at the sleeve joint.

[0008] The inner wall of the sleeve is sealed between the upper and lower ends and the outer wall of the rotating tube, with a rotating shaft and sealing ring installed.

[0009] Preferably, the top surface of the base plate has a circular groove, and a turntable is slidably and rotatably installed in the circular groove.

[0010] Preferably, two turbine fans are symmetrically and fixedly installed on the top surface of the turntable.

[0011] Preferably, limit blocks are symmetrically fixedly installed on the side wall of the turntable, and an annular groove is formed on the inner wall of the circular groove.

[0012] Preferably, the two limiting blocks fixedly installed on the side wall of the turntable are slidably connected to the inside of the two annular grooves opened on the inner wall of the circular groove.

[0013] Preferably, a sealing ring is fixedly bonded to the outer wall of the turntable, and the outer wall of the sealing ring is slidably fitted against the inner wall of the circular groove.

[0014] Compared with the prior art, the technical effects and advantages of this utility model are as follows:

[0015] The mixing device for this coagulation reaction tank, thanks to the arrangement of the casing, rotating pipe, mixing pipe and nozzle, allows the agent to be introduced into the inside of the casing through the inlet pipe and into the inside of the rotating pipe through the inlet hole on the side wall. At the same time, the agent can be introduced into the inside of multiple mixing pipes. Then, the agent can be sprayed into the wastewater in the reaction tank in a multi-point manner through multiple nozzles, thereby accelerating the mixing effect of the agent and wastewater.

[0016] Thanks to the sealing ring, the stirring device of this coagulation reaction tank can achieve a seal between the sleeve and the rotating pipe while also rotating to the outside of the rotating pipe, thereby improving the input effect of the reagent without affecting the rotation of the rotating pipe.

[0017] The mixing device of this coagulation reaction tank, thanks to the setting of a turntable and a turbine fan, can effectively turn the sewage inside the reaction tank upward by rotating the turntable and the turbine fan, thereby further improving the mixing effect of sewage and reagents.

[0018] Compared with existing technologies, this mixing device for the coagulation reaction tank can effectively improve the mixing efficiency of wastewater and reagents in the coagulation reaction tank. Attached Figure Description

[0030] like Figures 1 to 5The main structure of the coagulation reaction tank stirring device shown is a base plate 1 for installing the coagulation reaction tank and multiple stirring pipes 8 for stirring the coagulation reaction tank. A reaction cylinder 2 is fixedly installed on the top surface of the base plate 1, and arc-shaped plates 3 are symmetrically fixedly installed on the upper side wall of the reaction cylinder 2. An installation plate 4 is mounted on the top surface of the two arc-shaped plates 3.

[0031] A motor 5 is fixedly installed on the top surface of the mounting plate 4. A rotating tube 6 is fixedly installed at the end of the output shaft of the motor 5 and extends into the interior of the reaction cylinder 2. Multiple stirring tubes 8 are connected and installed on the side wall of the rotating tube 6. Multiple nozzles 9 are connected and installed on the side wall of the stirring tube 8.

[0032] A sleeve 10 is rotatably installed on the side wall of the rotating pipe 6. An infusion pipe is connected to the side wall of the sleeve 10. Multiple inlet holes are opened on the side wall of the rotating pipe 6, and the inlet holes are located at the sleeve 10. The upper and lower ends of the inner wall of the sleeve 10 are rotatably sealed between the outer wall of the rotating pipe 6 and the upper and lower ends. Thanks to the arrangement of the sleeve 10, the rotating pipe 6, the stirring pipe 8 and the nozzle 9, the agent is introduced into the inside of the sleeve 10 through the infusion pipe and into the inside of the rotating pipe 6 through the inlet holes on the side wall of the rotating pipe 6. At the same time, the agent can be introduced into the inside of multiple stirring pipes 8. Then, the agent can be sprayed into the sewage in the reaction cylinder 2 in a multi-point manner through multiple nozzles 9, thereby accelerating the mixing effect of the agent and the sewage.

[0033] A circular groove 11 is provided on the top surface of the base plate 1, and a turntable 12 is slidably and rotatably installed in the circular groove 11. Two turbine fans 13 are symmetrically and fixedly installed on the top surface of the turntable 12. Thanks to the setting of the turntable 12 and the turbine fans 13, the sewage inside the lower part of the reaction cylinder 2 can be effectively turned upward by rotating the turntable 12 and the turbine fans 13, thereby further improving the mixing effect of sewage and reagent.

[0034] Limiting blocks 15 are symmetrically fixedly installed on the side wall of the turntable 12. The inner wall of the circular groove 11 is provided with an annular groove. The two limiting blocks 15 fixedly installed on the side wall of the turntable 12 are slidably connected to the two annular grooves provided in the inner wall of the circular groove (11). The two limiting blocks 15 can effectively limit the rotation direction of the turntable 12, and further improve the rotation stability of the turntable 12.

[0035] A sealing ring 16 is fixedly bonded to the outer wall of the turntable 12. The outer wall of the sealing ring 16 is slidably fitted to the inner wall of the circular groove 11. The circular groove 11 can improve the sealing effect between the outer wall of the turntable 12 and the inner wall of the circular groove 11, thereby preventing sewage from entering the interior of the circular groove 11 through the gaps on the outer side of the turntable 12.

[0036] Working principle

[0037] In operation, the mixing device for the coagulation reaction tank first introduces wastewater into the reaction cylinder 2, then introduces the reagent through the infusion pipe into the sleeve 10. Subsequently, the reagent is introduced into the rotating pipe 6 and multiple stirring pipes 8 through multiple inlet holes on the side wall of the rotating pipe 6. The reagent is then evenly introduced into the reaction cylinder 2 through multiple nozzles 9 connected to the side wall of the stirring pipe 8. At the same time, the rotating pipe 6 and multiple stirring pipes 8 fixedly installed at its output end are rotated by the motor 5, which also evenly introduces the reagent into the reaction cylinder 2. This effectively accelerates the mixing efficiency of the reagent and wastewater. Simultaneously, the turntable 12 is activated, which drives the turbine fan 13 on its top surface to rotate. The turbine fan 13 then churns the wastewater at the lower end of the reaction cylinder 2 upwards, further improving the mixing effect of the wastewater and reagent.
