Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment tower technology, specifically to an ozone catalytic oxidation tower for industrial wastewater treatment. Background Technology

[0002] Ozone catalytic oxidation towers utilize the strong oxidizing properties of ozone to remove harmful substances from water through a catalytic reaction. Ozone can effectively degrade organic matter in water, especially pollutants that are difficult to biodegrade, such as pesticides and solvents. Through oxidation, these complex organic molecules are converted into simpler molecules, ultimately becoming carbon dioxide and water, thus achieving the purpose of removing organic matter. In addition, ozone also has excellent disinfection properties, effectively inactivating bacteria, viruses, and other microorganisms in water. Compared with traditional chlorine disinfection methods, ozone does not produce harmful byproducts. Structurally, an ozone catalytic reaction tower generally consists of a tower body, an ozone generator, a gas distribution system, a catalyst system, and an effluent system. The tower body is usually made of corrosion-resistant materials and has multiple reaction chambers inside to increase the contact time between ozone and wastewater, improving reaction efficiency. The ozone generator converts air or oxygen into ozone, and the generated ozone is evenly introduced into the water through the gas distribution system to ensure its full dissolution. Under the action of a catalyst, ozone reacts with pollutants in water to form smaller molecules, or even mineralizes into harmless carbon dioxide and water. For example, an ozone catalytic oxidation tower for wastewater treatment disclosed in authorization announcement number CN207792798U has a wastewater inlet on the upper side wall and a treated wastewater outlet on the lower side wall. The ozone catalytic oxidation tower has several catalyst layers inside, located between the inlet and the outlet. An ozone aeration device is installed between the lowest catalyst layer and the outlet, which fully mixes the wastewater with ozone gas and returns some of the remaining ozone in the exhaust gas to the oxidation tower, allowing more ozone to dissolve in the wastewater. However, the ozone catalytic oxidation tower in the above technical solution is still quite tall. Therefore, a ladder needs to be installed on the outside of the tower for workers to climb. During manual climbing, workers are prone to falls, especially in humid, windy, or inclement weather conditions. Workers may lack sufficient grip and foot strength, and carrying or moving tools and equipment on the ladder also poses safety hazards. If tools are not properly carried or secured, they may fall during the climb, injuring workers below or damaging the tower. Utility Model Content

[0003] The purpose of this utility model is to provide an ozone catalytic oxidation tower for industrial wastewater treatment. A primary square-mouth platform for initial ascent is set on the outside of the ozone catalytic oxidation tower, and a long U-shaped upright frame with an internal sprocket lifting structure is installed at the top of the primary square-mouth platform. The worker stands in the carrier box, and the worker on the primary square-mouth platform starts the worm gear reducer motor and sprocket lifting structure through the motor controller, so that the carrier box and the worker can be raised to different height positions of the tower body, thereby solving the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: an ozone catalytic oxidation tower for industrial wastewater treatment, comprising an ozone catalytic oxidation tower body and a primary square-mouth machine platform fixed to its outer periphery. A steel mesh platform is installed at the corner of the top of the primary square-mouth machine platform. A long U-shaped upright is fixed to one side of the top of the primary square-mouth machine platform. A carrier box is slidably installed on the outer wall of the long U-shaped upright near the ozone catalytic oxidation tower body. Both sides inside the long U-shaped upright are equipped with sprocket lifting structures for vertically lifting the carrier box. A worm gear reducer motor for driving the sprocket lifting structure is installed on one outer wall of the long U-shaped upright. A motor controller is installed on one side of the top of the steel mesh platform, and the output end of the motor controller is electrically connected to the input end of the worm gear reducer motor.

[0005] Preferably, an upward-extending ladder is fixed to one side of the surface of the primary square-mouth machine platform, and a guardrail is installed on the outside of the ladder.

[0006] Preferably, a number of longitudinal arms are installed at equal intervals on the back of the long U-shaped support frame, and one end of each longitudinal arm is fixedly connected to the outer wall of the ozone catalytic oxidation tower body.

[0007] Preferably, the outer wall of the carrier box near the ozone catalytic oxidation tower body is provided with an arc-shaped groove, the curvature of which is equal to the curvature of the outer wall surface of the ozone catalytic oxidation tower body.

[0008] Preferably, the sprocket lifting structure includes a drive shaft rotatably mounted on both sides inside the long U-shaped upright, sprockets fixed at both ends of the drive shaft surface, and a chain installed between the two sprockets in the same Z-axis direction. The output shaft of the worm gear reducer motor is fixedly connected to one end of one of the drive shafts via a coupling.

[0009] Preferably, a back plate is fixed to both sides of the back of the carrier, and a protruding foot is installed on one outer wall of the back plate, with the back of the protruding foot fixedly connected to one end of the chain.

[0010] Compared with existing technologies, the beneficial effects of this utility model are as follows: This ozone catalytic oxidation tower for industrial wastewater treatment has an electric lifting structure composed of a worm gear reducer motor, a sprocket lifting structure, and other components working together. Workers can be safely raised and lowered within the carrier, greatly reducing the safety hazards of working at heights. The design of the carrier effectively prevents workers from falling during the lifting process, thus avoiding accidents. Workers can also be raised and lowered quickly and smoothly to the required height, reducing physical burden and allowing them to focus more on actual inspection and maintenance work, significantly improving work efficiency. Furthermore, it can withstand the influence of the external environment to a certain extent under conditions of high wind speed or severe weather, ensuring the safety of workers.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the 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 scope of protection of the present utility model.

[0018] Please see Figure 1-5This utility model provides an embodiment of an ozone catalytic oxidation tower for industrial wastewater treatment, comprising an ozone catalytic oxidation tower body 1 and a primary square-mouth machine platform 2 fixed on its outer periphery. A steel mesh platform 5 is installed at the corner of the top of the primary square-mouth machine platform 2. A long U-shaped support frame 6 is fixed on one side of the top of the primary square-mouth machine platform 2. A carrier box 10 is slidably installed on the outer wall of the long U-shaped support frame 6 near the ozone catalytic oxidation tower body 1. The carrier box 10 carries the workers and their tools, providing a safe working space. Safety railings and protective nets can be equipped at the edge of the carrier box 10 to prevent workers from falling accidentally. Both sides inside the long U-shaped support frame 6 are equipped with sprocket lifting structures 8 for pulling the carrier box 10 vertically. The long U-shaped support frame 6 is installed on the top of the primary square-mouth machine platform 2, providing a support structure for lifting. Its shape design allows the carrier box 10 to maintain good stability during lifting.

[0019] A worm gear reducer motor 9 for driving the sprocket lifting structure 8 is installed on one outer wall of the long U-shaped upright frame 6. A motor controller 12 is installed on one side of the top of the steel grid platform 5. The output end of the motor controller 12 is electrically connected to the input end of the worm gear reducer motor 9.

[0020] In the initial stage of constructing the ozone catalytic oxidation tower body 1, working platforms can be installed at different heights of the tower body to facilitate workers to enter the working platforms at different heights via components such as the worm gear reducer motor 9, sprocket lifting structure 8, and carrier box 10.

[0021] The motor controller 12 is responsible for controlling the start and stop of the worm gear reducer motor 9, allowing the staff to precisely adjust the lifting height as needed;

[0022] A ladder 3 extending upwards is fixed on one side of the surface of the first-stage square-mouth machine platform 2, and a guardrail 4 is installed on the outside of the ladder 3. The ladder 3 and the guardrail 4 are located on the outside of the ozone catalytic oxidation tower body 1 and are connected to the first-stage square-mouth machine platform 2. It serves as the starting platform for the staff and can withstand the gravity and dynamic load during the lifting process.

[0023] An arc-shaped groove is provided on the outer wall of the container 10 near the ozone catalytic oxidation tower body 1. The curvature of the arc-shaped groove is equal to the curvature of the outer wall of the ozone catalytic oxidation tower body 1. Several longitudinal arms 601 are installed at equal intervals on the back of the long U-shaped support 6. One end of the longitudinal arm 601 is fixedly connected to the outer wall of the ozone catalytic oxidation tower body 1. The back of the long U-shaped support 6 is fixedly connected to the outer wall of the ozone catalytic oxidation tower body 1 through the longitudinal arms 601, so that the long U-shaped support 6 can withstand a greater load.

[0024] The sprocket lifting structure 8 includes a drive shaft 7 rotatably mounted on both sides inside the long U-shaped upright 6, sprockets fixed at both ends of the drive shaft 7, and a chain installed between the two sprockets in the same Z-axis direction. The output shaft of the worm gear reducer motor 9 is fixedly connected to one end of one of the drive shafts 7 via a coupling. Back plates 11 are fixed on both sides of the back of the carrier box 10. A protrusion 1101 is installed on one outer wall of the back plate 11. The back of the protrusion 1101 is fixedly connected to one end of the chain. When the worm gear reducer motor 9 drives the sprocket lifting structure 8, the rotational power of the worm gear reducer motor 9 is transmitted to the sprocket lifting structure 8 on both sides inside the long U-shaped upright 6, so that the sprockets and chain can rotate. The chain drives the carrier box 10 to rise and fall in the vertical direction of the long U-shaped upright 6, so that the workers can quickly reach the required height.

[0025] In this embodiment, before workers begin high-altitude operations, all components on the tower are inspected to ensure the motor controller 12, sprocket lifting structure 8, carrier 10, and other related components are in good working order. Necessary safety equipment, including safety belts and helmets, is worn to ensure safety during lifting. Two workers first ascend the first-stage square-mouth platform 2. One worker is positioned at the motor controller 12, while the other enters the carrier 10 via the platform. The motor controller 12 features simple buttons or switches, making it intuitive and easy to use. The motor controller 12 then starts the worm gear reducer motor 9, which drives the sprocket in the sprocket lifting structure 8 to rotate, causing the chain to move. At this point, the carrier 10 begins to move upwards or downwards along the long U-shaped support frame 6. The sprocket design ensures the smoothness and safety of the lifting process. The safety design of the carrier box 10 ensures that the work is safe and avoids violent vibrations. During the lifting process, the operator can observe the lifting height through the motor controller 12 and adjust it as needed. When the target height is reached, the operator can stop the worm gear reducer motor 9 through the controller to ensure that the carrier box 10 is stably stopped in the designated position. The operator in the carrier box 10 can carry various tools, which can be used conveniently by the operator during the operation, reducing unnecessary up and down movement. Through the safety design of the carrier box 10, the operator can safely carry out maintenance, inspection or monitoring work at high altitude without worrying about accidents. After the work is completed, the operator at the first-stage square-mouth machine 2 can use the motor controller 12 to start the worm gear reducer motor 9 and the sprocket lifting structure 8 again to safely lower the carrier box 10 back to the first-stage square-mouth machine 2. The descent process is also smooth, ensuring the safety of the operator and tools.
