[0001] This utility model relates to the field of aeration equipment technology, and in particular to a mobile sewage treatment aeration equipment. Background Technology

[0002] In water treatment processes, aeration equipment is a key component of biological pretreatment of water supply and biological treatment of wastewater. Aeration devices transfer oxygen from the air into the liquid in the aeration tank to supply the oxygen required for the metabolism of aerobic organisms, while simultaneously ensuring thorough and uniform mixing of the water in the tank to achieve the purpose of biological treatment.

[0003] A search revealed that CN215592743U is a wastewater treatment aeration device. However, this device is moved and supported by four casters distributed on the body, without any other support points. When moved to a designated position, the device cannot stay stably at the placement point, causing it to move and making it difficult to maintain a stable working state. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a mobile sewage treatment aeration device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A mobile sewage treatment aeration device includes a U-shaped frame. An aeration assembly for aerating sewage is located at the top of the frame. Two downward-opening cavities are located on both sides of the frame. Two sliders are slidably connected within each cavity. A bidirectional lead screw is rotatably connected within each cavity, passing through and threadedly connecting to the two sliders. Multiple guide grooves communicating with the cavities are located on the inner walls of both sides of the frame. A support frame is slidably connected below the bidirectional lead screw within each of the two cavities, passing through the guide grooves. Two casters are fixedly connected to the bottom of the support frame within the cavity. Two fixed seats are fixedly connected to the top of the support frame within the cavity. Connecting rods are rotatably connected within each fixed seat, and the two connecting rods are rotatably connected to the two sliders respectively. A guide component is provided within the cavity to allow the support frame to move vertically.

[0007] As a further embodiment of this utility model, the aeration assembly includes an aeration box, which is fixedly connected to the top of the frame. Aeration pipes are fixedly connected to both inner walls of the aeration box, and air pumps for conveying gas into the aeration pipes are fixedly connected to both outer walls of the aeration box.

[0008] As a further embodiment of this utility model, a sewage inlet pipe is fixedly connected to the top of the aeration box, and an outlet pipe is fixedly connected to one side of the aeration box near the bottom, with a valve provided on the outside of the outlet pipe.

[0009] As a further embodiment of this utility model, the bottom of the aeration box and the top of the frame are provided with impurity discharge ports, and a baffle is snapped into the impurity discharge port.

[0010] As a further embodiment of this utility model, a drive motor is fixedly connected to the top outer wall of the aeration box, one end of the output shaft of the drive motor passes through the aeration box and is fixedly connected to a rotating shaft, and multiple slurry dispersing devices are fixedly connected to the outside of the rotating shaft.

[0011] As a further embodiment of this invention, a pressure gauge for detecting the internal air pressure of the aeration box is fixedly connected to the top of the aeration box.

[0012] As a further embodiment of this utility model, the guiding component consists of two guide rods, both of which are fixedly connected within the cavity and pass through the support frame.

[0013] As a further improvement of this utility model, one end of the bidirectional lead screw passes through the frame and is fixedly connected to a handwheel.

[0014] The beneficial effects of this utility model are as follows:

[0015] 1. By using the frame and casters together, the aeration equipment can be moved when supported by the casters. When the aeration equipment is moved to the designated position, the frame supports it, thus preventing the aeration equipment from moving after it has been moved to the designated position. This ensures that the aeration equipment is placed stably and improves the stability of the aeration equipment during use.

[0016] 2. Through the combined use of the rotating shaft and the dispersing slurry, the motor drives the rotating shaft to rotate, and the rotating shaft drives the dispersing slurry to rotate. The dispersing slurry can fully disperse the sewage and make full contact with the air. Furthermore, the sewage entering the aeration box is repeatedly dispersed by the dispersing slurry, thus fully playing the role of aeration for the sewage and having a good aeration effect.

[0017] 3. By setting a pressure gauge, the pressure inside the aeration box can be detected, thereby preventing the aeration box from becoming too pressurized and causing danger, thus improving the safety of the aeration equipment. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. The described embodiments are only some embodiments of the present utility model, not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0023] Reference Figures 1-3A mobile sewage treatment aeration device includes a U-shaped frame 1. The top of the frame 1 is equipped with an aeration assembly for aerating sewage. Two downward-opening cavities are located on both sides of the frame 1. Two sliders 17 are slidably connected within each cavity. A bidirectional lead screw 16 is rotatably connected within each cavity, passing through and threadedly connecting to the two sliders 17. Multiple guide grooves communicating with the cavities are provided on the inner walls of both sides of the frame 1. Support frames 12 are slidably connected below the bidirectional lead screw 16 within the two cavities, passing through the guide grooves. Two casters 14 are bolted to the bottom of the support frames 12 within the cavities. Two fixed seats 18 are bolted to the top of the support frames 12 within the cavities. Connecting rods 15 are rotatably connected within the fixed seats 18, and each connecting rod 15 is rotatably connected to one of the two sliders 17. The cavities are equipped with... The support frame 12 is a guide component for vertical movement. When movement is required, the two bidirectional lead screws 16 rotate synchronously. The two bidirectional lead screws 16 drive the sliders 17 connected to them to move through the threaded engagement between the two bidirectional lead screws 16 and the sliders 17, thereby causing the two sliders 17 on the bidirectional lead screws 16 to move in opposite directions. During the movement, the sliders 17 push the support frame 12 downward through the connecting rod 15, causing the casters 14 to move out of the cavity and support the frame 1. At this time, the frame 1 can be moved by the casters 14, thereby moving the aeration equipment. When the aeration equipment is moved to the designated position, the bidirectional lead screws 16 rotate in the opposite direction, thereby retracting the casters 14 into the cavity. At this time, the frame 1 will contact the ground for support, thus preventing the aeration equipment from moving after it has been moved to the designated position, ensuring stable placement of the aeration equipment and improving the stability of the aeration equipment in use.

[0024] In this utility model, the aeration assembly includes an aeration box 3, which is fixed to the top of the frame 1 by bolts. Aeration pipes 8 are fixed to the inner walls of both sides of the aeration box 3 by bolts. Air pumps 2 for conveying gas into the aeration pipes 8 are fixed to the outer walls of both sides of the aeration box 3 by bolts. A sewage inlet pipe 4 is welded to the top of the aeration box 3. An outlet pipe 6 is welded to one side of the aeration box 3 near the bottom. A valve is provided on the outside of the outlet pipe 6. After sewage is added into the aeration box 3 through the sewage inlet pipe 4, air is compressed and delivered to the aeration pipes 8 by the air pump 2 to aerate the sewage. After aeration, the sewage will be discharged from the aeration box 3 through the outlet pipe 6. Impurity discharge outlets 11 are opened at the bottom of the aeration box 3 and the top of the frame 1. A baffle is snapped into the impurity discharge outlet 11. After aeration, the impurities remaining in the aeration box 3 can be discharged from the aeration box 3 through the impurity discharge outlet 11.

[0025] In particular, a drive motor is bolted to the top outer wall of the aeration box 3. One end of the drive motor's output shaft passes through the aeration box 3 and is bolted to a rotating shaft 10. Multiple dispersing slurries 9 are bolted to the outside of the rotating shaft 10. During the wastewater aeration process, the drive motor drives the rotating shaft 10 to rotate, which in turn drives the dispersing slurries 9 to rotate. The dispersing slurries 9 can effectively disperse the wastewater and ensure it has sufficient contact with air. Furthermore, the wastewater entering the aeration box 3 is repeatedly dispersed by the dispersing slurries 9, thus effectively aerating the wastewater and achieving a good aeration effect. The top of the aeration box 3 is bolted to a set of aeration devices. Pressure gauge 5 is used to detect the internal air pressure of the aeration box 3. Pressure gauge 5 can detect the pressure inside the aeration box 3, thereby avoiding the danger caused by excessive gas pressure in the aeration box 3 and improving the safety of the aeration equipment. The guiding components are two guide rods 13, both of which are fixed in the cavity by bolts. The guide rods 13 pass through the support frame 12 and guide the movement of the support frame 12, thereby ensuring that the support frame 12 can move vertically up and down. One end of the bidirectional screw 16 passes through the frame 1 and is fixed to a handwheel 7 by bolts. The bidirectional screw 16 can be rotated by the handwheel 7.

[0026] Working principle: When movement is required, the two bidirectional lead screws 16 are rotated synchronously. The two bidirectional lead screws 16 drive the sliders 17 connected to them to move through the threaded engagement between the two bidirectional lead screws 16 and the sliders 17, thereby causing the two sliders 17 on the bidirectional lead screws 16 to move in opposite directions. During the movement, the sliders 17 push the support frame 12 downward through the connecting rod 15. At the same time, the connecting rod 15 rotates between the sliders 17 and the fixed seat 18. The support frame 12 drives the casters 14 to move, causing the casters 14 to move out of the cavity and support the frame 1. At this point, the frame 1 can be moved using the casters 14, thereby moving the aeration equipment. Once the aeration equipment has moved to the designated position, the double-acting screw 16 rotates in the opposite direction, causing the two sliders 17 on the double-acting screw 16 to move towards each other. This causes the support frame 12 to move upward, retracting the casters 14 into the cavity. This allows the frame 1 to contact the ground for support, preventing the aeration equipment from moving after it has been moved to the designated position. This ensures the aeration equipment is placed stably and improves the stability of its use.

[0027] Furthermore, although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
