Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically to a wastewater aeration and sterilization device. Background Technology

[0002] In the wastewater treatment process, certain methods and equipment are used to force air into the wastewater, so that the wastewater in the pool comes into contact with the air and is oxygenated. This agitates the liquid, accelerates the transfer of oxygen from the air into the liquid, prevents suspended objects in the pool from settling, and enhances the contact between organic matter, microorganisms, and dissolved oxygen in the pool, thereby oxidizing and decomposing the organic matter in the wastewater. This process of forcibly increasing oxygen in wastewater is called aeration.

[0003] Publication number CN208948981U discloses a wastewater aeration and sterilization device. This patent uses a water pump to extract disinfectant from the storage tank and impact a turbine, which in turn drives the casing and spray pipe to rotate, improving the uniformity of disinfectant spraying and ensuring the sterilization effect of the water. This solves the problem of poor sterilization effect of existing aeration and sterilization devices on water bodies. However, this patent still has the following problems in actual use:

[0004] The water pump can extract the disinfectant from the storage tank and impact the turbine, which in turn drives the casing and spray pipe to rotate, improving the uniformity of disinfectant spraying and ensuring the sterilization effect of the water. However, in actual use, if the disinfectant impacts the worm gear to drive the spray pipe to rotate, the pressure requirement after the disinfectant is extracted is too high, and the rotation speed of the spray pipe will not be too fast. In addition, the position of the exhaust frame is always fixed, and the aeration range is relatively fixed, which cannot guarantee the efficiency and uniformity of aeration.

[0005] A wastewater aeration and sterilization device is proposed to address the problems mentioned above. Utility Model Content

[0006] The purpose of this invention is to provide a wastewater aeration and sterilization device to solve the problems mentioned in the background art. Currently, a water pump can extract disinfectant from the storage tank and impact a turbine, which drives the casing and spray pipe to rotate, improving the uniformity of disinfectant spraying and ensuring the sterilization effect of the water. However, in actual use, if the disinfectant impacts the worm gear to drive the spray pipe to rotate, the pressure requirement after the disinfectant is extracted is too high, the rotation speed of the spray pipe will not be too fast, and the position of the exhaust frame is always fixed, resulting in a relatively fixed aeration range, which cannot guarantee the efficiency and uniformity of aeration.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a wastewater aeration and sterilization device, comprising a float plate;

[0008] A storage tank is fixedly installed on one side of the top of the float, and an oxygenation pump is fixedly installed on the other side of the top of the float, with an air inlet pipe connected through the outlet of the oxygenation pump.

[0009] Also includes:

[0010] The bottom of the float is fixedly installed with a fixed frame, and the bottom and one side of the fixed frame are fixedly installed with connecting frames. The air inlet pipe is fixedly connected to the connecting frame. The inner center of the float is rotatably connected with a hollow tube, and the bottom end of the hollow tube is connected to a liquid outlet pipe. The bottom of the liquid outlet pipe is connected to several liquid outlets.

[0011] The bottom center of the liquid outlet pipe is fixedly installed with a rotating rod, and a support frame is fixedly installed on the inner side of the fixed frame. The rotating rod is rotatably connected to the support frame. The bottom end of the rotating rod is fixedly installed with an air outlet pipe, and the top of the air outlet pipe is provided with several liquid outlets. The top of the float plate is provided with a rotating assembly.

[0012] The bottom of the air outlet pipe is connected to a connecting pipe, which is rotatably connected to the fixed frame. One end of the air inlet pipe is rotatably connected to the connecting pipe via a rotary joint.

[0013] Preferably, the rotating assembly includes a support platform fixedly installed on the top of the float on one side of the hollow tube, and a drive motor is fixedly installed on the top of the support platform. The output end of the drive motor is rotatably connected to the float. A first pulley is fixedly installed outside the output end of the drive motor, and a second pulley is fixedly installed outside the hollow tube above the float. The first pulley is rotatably connected to the second pulley via a belt.

[0014] Preferably, the top of the hollow tube is rotatably connected to an installation pipe via a rotating joint, and the top of the float plate is fixedly installed on the other side of the hollow tube with a cylinder body, and the installation pipe is connected through the cylinder body. Furthermore, a liquid extraction pipe is connected through one side of the cylinder body, and the end of the liquid extraction pipe away from the cylinder body is connected through the storage tank.

[0015] Preferably, a piston is slidably connected inside the cylinder, and a movable rod is fixedly installed on one side of the piston, and the movable rod is slidably connected to the cylinder.

[0016] Preferably, a limiting frame is slidably connected to the outer side of the movable rod, and the limiting frame is fixedly connected to the float.

[0017] Preferably, a turntable is fixedly installed on the outside of the hollow tube above the second pulley, and a T-shaped annular groove is opened on the outer side of the turntable. An arc-shaped block is fixedly installed on the end of the movable rod away from the cylinder, and the arc-shaped block is fixedly connected to the T-shaped annular groove.

[0018] Preferably, a one-way valve is provided on one side of both the installation tube and the liquid extraction tube.

[0019] Compared with the prior art, the beneficial effects of this utility model are: this sewage aeration and sterilization device allows the liquid outlet pipe and the air outlet pipe to rotate together during the aeration and sterilization process, ensuring uniform aeration while evenly distributing the disinfectant, thus improving practicality. The specific details are as follows:

[0020] 1. During the aeration and sterilization process of wastewater, the oxygenation pump is started, allowing oxygen to enter the connecting pipe through the air inlet pipe and then into the air outlet pipe. The oxygen leaks out through the air outlet pipe to aerate the wastewater. The drive motor is started, and the connection between the first and second pulleys drives the hollow tube to rotate. The disinfectant enters the liquid outlet pipe through the hollow tube and is sprayed through the liquid outlet on the liquid outlet pipe. The rotation of the hollow tube drives the rotation of the liquid outlet pipe, and the rotation of the liquid outlet pipe can drive the rotation of the air outlet pipe together through the rotating rod. This allows for the simultaneous and uniform spraying of disinfectant and aeration. In addition, a baffle plate is installed at the bottom of the float plate to prevent the float plate from rotating. This allows the liquid outlet pipe and the air outlet pipe to rotate together during the aeration and sterilization process, ensuring uniform aeration while uniformly spraying disinfectant, thus improving practicality.

[0021] 2. As the hollow tube rotates continuously, it drives the turntable to rotate in an offset manner. After the turntable rotates in an offset manner, it drives the movable rod to move back and forth through the connection between the T-shaped annular groove and the arc-shaped block. The movable rod slides on the limit frame to limit its movement, which in turn allows the piston to move back and forth in the cylinder. When the piston moves to the right, the one-way valve inside the installation tube closes, and the one-way valve inside the extraction tube opens. The movement of the piston in the cylinder can draw the disinfectant from the storage tank into the cylinder. When the piston moves to the left, the one-way valve inside the installation tube opens, and the one-way valve inside the extraction tube closes, allowing the disinfectant inside the cylinder to be pushed into the installation tube, so that the disinfectant can enter the hollow tube. This makes it convenient to extract the disinfectant while driving the hollow tube to rotate, eliminating the need for an external pump and improving practicality. Attached Figure Description

This allows the liquid outlet pipe 106 and the air outlet pipe 109 to rotate together during the aeration and sterilization process, ensuring uniform aeration while evenly distributing the disinfectant, thus improving practicality.

[0030] The rotating assembly 2 includes a support platform 201 fixedly installed on the top of the float 1, located on one side of the hollow tube 105. A drive motor 202 is fixedly installed on the top of the support platform 201, and the output end of the drive motor 202 is rotatably connected to the float 1. A first pulley 203 is fixedly installed outside the output end of the drive motor 202, and a second pulley 204 is fixedly installed on the outside of the hollow tube 105, located above the float 1. The first pulley 203 is rotatably connected to the second pulley 204 via a belt, which can drive the hollow tube 105 to rotate. An installation pipe 205 is rotatably connected to the top of the hollow tube 105 via a rotating joint. A cylinder 206 is fixedly installed on the top of the float 1, located on the other side of the hollow tube 105, and the installation pipe 205 is connected through the cylinder 206. A liquid extraction pipe 207 is connected through one side of the cylinder 206, and the end of the liquid extraction pipe 207 away from the cylinder 206 is connected through the storage tank 101, which can be used to extract liquid from the storage tank 101. 01. To extract the detoxifying liquid, a piston 209 is slidably connected inside the cylinder 206, and a movable rod 210 is fixedly installed on one side of the piston 209. The movable rod 210 is slidably connected to the cylinder 206, so that the movement of the movable rod 210 can drive the piston 209 to move within the cylinder 206.

An arc-shaped block 213 is fixedly installed at the end of the movable rod 210 away from the cylinder 206, and the arc-shaped block 213 is fixedly connected to the T-shaped annular groove 212, so that the rotation of the hollow tube 105 can drive the movable rod 210 to move back and forth. One-way valves are provided on one side of the installation tube 205 and the liquid extraction tube 207 to facilitate the extraction of detoxification liquid.

[0031] Working principle: Before using this type of wastewater aeration and sterilization device, it is necessary to check the overall condition of the device to ensure that it can operate normally. Figure 1 - Figure 5As shown, during the aeration and sterilization process of wastewater, the oxygenation pump 102 is started, allowing oxygen to enter the connecting pipe 110 through the air inlet pipe 103 and then into the air outlet pipe 109. The oxygen leaks out through the air outlet pipe 109 to aerate the wastewater. The drive motor 202, connected to the first pulley 203 and the second pulley 204, drives the hollow tube 105 to rotate. Disinfectant solution enters the outlet pipe 106 through the hollow tube 105 and is sprayed through the outlet on the outlet pipe 106. During the rotation of the hollow tube 105, the liquid outlet tube 106 can be driven to rotate. During the rotation of the liquid outlet tube 106, the air outlet tube 109 can be driven to rotate together through the rotating rod 107. Disinfectant can be evenly sprayed and aerated at the same time. In use, a baffle plate is set at the bottom of the float plate 1 to prevent the float plate 1 from rotating. This allows the liquid outlet tube 106 and the air outlet tube 109 to rotate together during the aeration and sterilization process. This ensures the uniformity of aeration while evenly spraying disinfectant, thus improving practicality.

[0032] As the hollow tube 105 rotates continuously, it drives the turntable 208 to rotate in an offset manner. After the turntable 208 rotates in an offset manner, it drives the movable rod 210 to move back and forth through the connection between the T-shaped annular groove 212 and the arc-shaped block 213. The movable rod 210 slides on the limit frame 211 for limitation, thereby allowing the piston 209 to move back and forth in the cylinder 206. When the piston 209 moves to the right, the one-way valve inside the mounting tube 205 closes, and the one-way valve inside the suction tube 207 opens, allowing the piston to move back and forth. The movement of piston 209 within cylinder 206 draws the disinfectant from storage tank 101 into cylinder 206. When piston 209 moves to the left, the one-way valve inside installation tube 205 opens, and the one-way valve inside extraction tube 207 closes, allowing the disinfectant from cylinder 206 to be pushed into installation tube 205. This allows the disinfectant to enter hollow tube 105, facilitating the extraction of disinfectant while rotating hollow tube 105, eliminating the need for an external pump and improving practicality.

[0033] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
