Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of sewage treatment, in particular to an aeration device for sewage treatment. Background Art
[0002] Aerators are essential equipment for aeration and oxygenation of water supply and drainage. According to the method of use, they can be divided into surface aerators and underwater aerators. Underwater aerators mainly include microporous aerators and jet aerators. The oxygenation efficiency and power efficiency of the equipment are improved compared with ordinary microporous aeration equipment, and they are easy to maintain. Damaged aerators can be inspected and replaced without affecting normal operation (without stopping water supply or air supply). The oxygen supply is uniform, the oxygen utilization rate is high, and the energy consumption is low.
[0003] The aeration devices currently on the market generally have fixed exhaust nozzles for exhausting air for utilization by microorganisms and are arranged facing upward. When exhausting air, the upward movement of bubbles will be accelerated, so that the bubbles will stay in the water for a short time, which is not conducive to utilization by microorganisms. In addition, the fixed exhaust nozzle has an effective area for bubble dissipation. A single exhaust nozzle can only aerate a fixed area, resulting in dead corners and poor aeration quality. Therefore, an aeration device for sewage treatment is proposed to address the above problems. Utility Model Content
[0004] The purpose of the present utility model is to provide an aeration device for sewage treatment to solve the problems raised in the above background technology.
[0005] To achieve the above objectives, the present invention provides the following technical solutions:
[0006] As an optional solution of the aeration device for sewage treatment described in the utility model, wherein: an aeration device for sewage treatment includes an aeration tank, an air pump and an air pipe;
[0007] An air pump is provided on one side of the aeration tank, and an air pipe is fixedly connected to the exhaust end of the air pump, and a reciprocating mechanism is slidably connected to the other side of the air pipe;
[0008] A stirring mechanism is also installed inside the aeration tank;
[0009] The reciprocating mechanism includes a motor, a threaded shaft and a threaded sleeve. The end of the main shaft of the motor is fixedly connected to the threaded shaft, and the outer side of the threaded shaft is spirally connected to the threaded sleeve. The other end of the threaded sleeve is fixedly connected to the moving tube, and the other end of the moving tube is slidably connected to the air pipe.
[0010] The outer side of the movable tube is slidably connected to a sealing sleeve, and the outer side of the sealing sleeve is fixedly connected to the aeration tank;
[0011] The bottom of the movable pipe is connected with evenly distributed aeration nozzles, and the top of the movable pipe is connected with an air guide pipe.
[0012] As an optional solution of the aeration device for sewage treatment described in the utility model, one side of the bottom of the movable pipe is fixedly connected to a guide plate, and the bottom of the guide plate is slidably connected to the aeration tank.
[0013] As an optional solution of the aeration device for sewage treatment described in the utility model, the air guide pipe is arranged at an angle.
[0014] As an optional solution of the aeration device for sewage treatment described in the utility model, the opening of the aeration nozzle is arranged downward.
[0015] The aeration devices currently on the market generally have fixed exhaust nozzles for exhausting air for use by microorganisms and are set facing upward. When exhausting air, the bubbles will move upward faster, so that the bubbles will stay in the water for a shorter time, which is not conducive to the use of microorganisms. In addition, the fixed exhaust nozzle has an effective area for bubble dissipation. A single exhaust nozzle can only aerate a fixed area, which has dead corners and poor aeration quality. When in use, an external power supply is connected, and the motor drives the threaded shaft to rotate, and the threaded shaft drives the outer threaded sleeve to move, so that the movable tube moves back and forth, and finally the aeration nozzle moves back and forth left and right, expanding the bubble dissipation range of the aeration nozzle and ensuring the aeration quality.
[0016] As an optional solution of the aeration device for sewage treatment described in the utility model, the stirring mechanism includes a stirring shaft, a stirring plate and a power plate, the two ends of the stirring shaft are rotatably connected to the aeration tank, the outer side of the stirring shaft is fixedly connected with evenly distributed stirring plates, and one side of the stirring shaft is also fixedly connected with evenly distributed power plates.
[0017] The provided air guide pipe can blow the power plate, which helps the stirring shaft to rotate, thereby causing the stirring plate to rotate to stir the water body, further ensuring the aeration quality of the aeration device.
[0018] Compared with the prior art, the beneficial effects of the present invention are:
[0019] When the utility model is in use, the motor drives the threaded shaft to rotate, and the threaded shaft drives the outer threaded sleeve to move, so that the movable tube moves back and forth, and finally the aeration nozzle moves back and forth left and right, thereby expanding the bubble dissipation range of the aeration nozzle and ensuring the aeration quality;
[0020] The aeration nozzle is set facing downwards, which can slow down the rising speed of bubbles and prolong the time bubbles stay in the water, which is conducive to the absorption and use of microorganisms. At the same time, it can lift up the impurities deposited below to ensure the aeration quality.
[0021] The air guide pipe provided at the same time can blow the power plate, which helps the stirring shaft to rotate, thereby causing the stirring plate to rotate and stir the water body, further ensuring the aeration quality of the aeration device. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0027] Example 1: Please refer to Figure 1 and Figure 2 , the utility model provides a technical solution:
[0028] An aeration device for sewage treatment, comprising an aeration tank 1, an air pump 2 and an air pipe 3;
[0029] An air pump 2 is provided on one side of the aeration tank 1, and an air pipe 3 is fixedly connected to the exhaust end of the air pump 2, and a reciprocating mechanism 4 is slidably connected to the other side of the air pipe 3;
[0030] A stirring mechanism 5 is also installed inside the aeration tank 1;
[0031] The reciprocating mechanism 4 includes a motor 401, a threaded shaft 402, and a threaded sleeve 403. The end of the main shaft of the motor 401 is fixedly connected to the threaded shaft 402, and the outer side of the threaded shaft 402 is spirally connected to the threaded sleeve 403. The other end of the threaded sleeve 403 is fixedly connected to a moving tube 404, and the other end of the moving tube 404 is slidably connected to the air pipe 3.
[0032] The outer side of the movable tube 404 is slidably connected to a sealing sleeve 405, and the outer side of the sealing sleeve 405 is fixedly connected to the aeration tank 1;
[0033] The bottom of the moving pipe 404 is connected to evenly distributed aeration nozzles 407 , and the top of the moving pipe 404 is connected to an air guide pipe 406 .
[0034] A guide plate 408 is fixedly connected to one side of the bottom of the movable pipe 404 , and the bottom of the guide plate 408 is slidably connected to the aeration tank 1 .
[0035] The air guide tube 406 is arranged at an angle.
[0036] The opening of the aeration nozzle 407 is arranged downward.
[0037] The aeration devices currently on the market generally have an exhaust nozzle for exhausting air for utilization by microorganisms that is fixed and faces upward. When exhausting air, it accelerates the upward movement of bubbles, resulting in a shorter residence time of bubbles in the water body, which is not conducive to utilization by microorganisms. In addition, the fixed exhaust nozzle has an effective area for bubble dissipation. A single exhaust nozzle can only aerate a fixed area, resulting in dead corners and poor aeration quality. When in use, an external power supply is connected, and the motor 401 drives the threaded shaft 402 to rotate. The threaded shaft 402 drives the outer threaded sleeve 403 to move, thereby causing the movable tube 404 to reciprocate, and finally causing the aeration nozzle 407 to reciprocate left and right, thereby expanding the bubble dissipation range of the aeration nozzle 407 and ensuring the aeration quality.
[0038] In this embodiment, the aeration nozzle 407 is arranged facing downward, which can slow down the rising speed of bubbles and prolong the time the bubbles stay in the water, which is conducive to absorption and use by microorganisms. At the same time, it can lift up impurities deposited below to ensure the quality of aeration. A one-way valve is also installed on the outside of the air pipe 3 to ensure that the gas can only flow in one direction to prevent water backflow and damage to the equipment. The air guide pipe 406 is arranged at an angle to ensure that the stirring mechanism 5 above is blown to ensure its rotation, thereby achieving the purpose of stirring. No additional stirring equipment is required, reducing the investment cost.
[0039] The setting of the guide plate 408 can ensure that the movable tube 404 can only move left and right, preventing it from rotating itself, thereby ensuring the normal use of the equipment. The setting of the sealing sleeve 405 can prevent the water inside the aeration tank 1 from leaking out. Even if leakage occurs, it has little impact on the overall situation. At the same time, it can be collected by placing an external water collection frame below and then re-pumped into the aeration tank 1 through a circulation pump.
[0040] Example 2: This example is an improvement on Example 1. Figure 3Specifically, the stirring mechanism 5 includes a stirring shaft 501, a stirring plate 502 and a power plate 503. Both ends of the stirring shaft 501 are rotatably connected to the aeration tank 1. The outer side of the stirring shaft 501 is fixedly connected with evenly distributed stirring plates 502, and one side of the stirring shaft 501 is also fixedly connected with evenly distributed power plates 503.
[0041] The air guide pipe 406 can blow the power plate 503, which helps the stirring shaft 501 to rotate, thereby rotating the stirring plate 502 to stir the water, further ensuring the aeration quality of the aeration device;
[0042] In this embodiment, the power plate 503 can drive the stirring shaft 501 to rotate under the action of the air guide tube 406, so that the outer stirring plate 502 stirs the water body to ensure the aeration quality.
