Description

Technical Field

[0001] This utility model relates to the field of environmental protection technology, specifically to an ozone collection and emission device for a corona treatment machine. Background Technology

[0002] Corona treatment machines are mainly used for surface treatment of plastic film or plastic sheet products, giving the product surface stronger adhesion and preventing problems such as printing color bleeding, weak bonding, and uneven coating during the production process. During operation, the corona treatment machine will generate ozone, which is a byproduct of high-voltage discharge. Ozone has strong oxidizing properties and is harmful to the human body and may corrode equipment at high concentrations. Therefore, an effective ozone removal device is required.

[0003] Chinese patent CN 209476892 U discloses a corona treatment machine, including a corona treatment machine body, a frame, a corona treatment roller inside the frame, a discharge electrode frame fixedly connected to the upper end of the frame, and an ozone removal box on the corona treatment machine body.

[0004] The above-mentioned technical solution involves absorbing ozone and then discharging it outdoors. Directly discharging ozone without treatment may cause environmental pollution. Furthermore, the high-efficiency corona treatment machine generates heat during operation, and the hot fumes at the outlet may burn people passing by the equipment when discharged directly, posing a certain safety hazard. Summary of the Invention

[0005] The purpose of this invention is to provide an ozone collection and emission device for a corona treatment machine to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an ozone collection and emission device for a corona treatment machine, comprising a body, a cooling box at the top of the body, a connecting pipe at the top of the cooling box, an ultraviolet treatment chamber at one end of the connecting pipe, an exhaust plate inside the connecting pipe, an exhaust fan at the bottom of the exhaust plate, a flow guide inside the connecting pipe below the exhaust fan, a filter cartridge inside the flow guide, a plurality of ultraviolet lamps inside the ultraviolet treatment chamber, and a mirror coating on the inner wall of the ultraviolet treatment chamber.

[0007] Preferably, the cooling box has a heat dissipation plate inside, and a circulation pipe is installed inside the cooling box above the heat dissipation plate. One end of the circulation pipe extends out of the cooling box, and a circulating water tank is installed at the extended end of the circulation pipe. A water pump is installed in the circulating water tank. The top of the heat dissipation plate is made of aluminum heat sink, which can guide the gas and reduce the probability of turbulence. The circulation pipe is made of copper pipe. When the machine is running, the gas rises and comes into contact with the circulation pipe. When the low-temperature liquid absorbs heat, it is drawn into the circulating water tank by the water pump and transported to the inside of the circulation pipe. The circulation pipe stores the low-temperature liquid and circulates through the circulating water tank to cool the gas.

[0008] Preferably, an exhaust pipe is provided at the bottom center of the ultraviolet treatment box, and support legs are provided at the four corners of the bottom of the ultraviolet treatment box. The exhaust pipe discharges the treated gas, and the support legs support the ultraviolet treatment box so that the ultraviolet treatment box can be placed stably on a flat surface.

[0009] Preferably, the front end of the machine body is hinged with an opening and closing door. The opening and closing door can seal the machine body, keeping it in a relatively sealed state during operation and reducing the risk of ozone leakage. When feeding materials or performing equipment maintenance, the opening and closing door can be opened to allow the front end of the machine body to be opened for easy operation.

[0010] Preferably, a connecting pipe extends from one end of the filter cartridge, and a cap is threaded to the extended end of the filter cartridge. An activated carbon filter element is inserted inside the filter cartridge. The activated carbon filter element has a columnar structure. After the filter element is installed, the cap is installed on the extended end of the filter cartridge to keep the filter cartridge in a sealed state and prevent leakage of ozone-carrying gas.

[0011] Preferably, the top and bottom of the flow guide are provided with openings, and the top and bottom of the filter cartridge are provided with ventilated sections near the openings of the flow guide. When the exhaust fan is running, the connecting pipe will draw in air, and the gas carrying ozone will come into contact with the filter cartridge through the flow guide and ventilated sections, and be adsorbed by the filter cartridge.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] The ozone removal device of this high-efficiency corona treatment machine uses a filter cartridge inside the connecting pipe and an ultraviolet treatment box at the bottom of the connecting pipe. When the machine generates ozone during operation, the connecting pipe absorbs the flue gas. The flue gas first comes into contact with the activated carbon filter cartridge inside the filter cartridge. The porous structure of the activated carbon adsorbs the ozone and catalytically decomposes it into oxygen. Ozone may still remain in the flue gas after adsorption. The flue gas is then conveyed by the connecting pipe to the ultraviolet treatment box, where ultraviolet lamps release ultraviolet light. The ozone absorbs the ultraviolet energy and decomposes into oxygen. Then, the free oxygen atoms combine with the undecomposed ozone to further generate oxygen, thus fully treating the flue gas and preventing residual ozone in the flue gas from causing harm to personnel.

[0014] The ozone removal device of this high-efficiency corona treatment machine uses a cooling box. The heat generated during the machine's operation rises into the cooling box and is cooled down. This allows the ozone removal device to cool the machine and the flue gas, preventing burns to workers from the high-temperature flue gas. Attached Figure Description

They are used only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0022] like Figures 1 to 4 As shown, the ozone removal device of the high-efficiency corona treatment machine in this embodiment includes a body 1. A cooling box 5 is installed at the top of the body 1. When the body 1 is running, it generates heat, which rises and enters the cooling box 5, preventing the components inside the body 1 from overheating and causing a short circuit. A connecting pipe 4 is installed at the top of the cooling box 5. The connecting pipe 4 is used to transport the flue gas generated during the operation of the body 1. An ultraviolet treatment box 3 is installed at one end of the connecting pipe 4. An exhaust plate 13 is installed inside the connecting pipe 4. An exhaust fan 14 is installed at the bottom of the exhaust plate 13. The exhaust fan 14 contains a motor. When the exhaust fan 14 is running, it draws air from the cooling box 5 through the bottom of the connecting pipe 14, creating a negative pressure at the top of the body 1 and absorbing the flue gas generated during the operation of the body 1 into the interior of the connecting pipe 4. Inside the connecting pipe 4 below the exhaust fan 14, there is a flow guide 16. Inside the flow guide 16, there is a filter cartridge 17. Inside the filter cartridge 17, there is an activated carbon filter. When the connecting pipe 4 absorbs the flue gas, the flue gas will pass through the filter cartridge 17 and come into full contact with the activated carbon filter for adsorption treatment. Inside the ultraviolet treatment box 3, there are several ultraviolet lamps 11. When the connecting pipe 4 delivers the flue gas into the ultraviolet treatment box 3, the ultraviolet lamps 11 release ultraviolet light. Ozone absorbs the ultraviolet energy and decomposes into oxygen. Then, the free oxygen atoms combine with the undecomposed ozone to further generate oxygen, thus removing ozone from the flue gas. The inner wall of the ultraviolet treatment box 3 is provided with a mirror coating 12, which can enhance the light reflection efficiency.

[0023] Specifically, the cooling box 5 has a heat dissipation plate 7 inside, and a circulation pipe 6 is installed inside the cooling box 5 above the heat dissipation plate 7. One end of the circulation pipe 6 extends out of the cooling box 5, and a circulation water tank 8 is installed at the extended end of the circulation pipe 6. A water pump is installed inside the circulation water tank 8, and the output end of the water pump is connected to one end of the circulation pipe 6. The top of the heat dissipation plate 7 is made of aluminum heat sink, which can guide the gas and reduce the probability of turbulence. The circulation pipe 6 is made of copper pipe. When the machine body 1 is running, the gas rises and comes into contact with the circulation pipe 6. The circulation pipe 6 stores a low-temperature liquid. When the low-temperature liquid absorbs heat, it is drawn into the circulation water tank 9 by the pump and transported to the inside of the circulation pipe 6. The gas is circulated through the circulation water tank 8 to cool it down.

[0024] Furthermore, an exhaust pipe 10 is provided at the bottom center of the ultraviolet treatment chamber 3, and support legs 9 are provided at the four corners of the bottom of the ultraviolet treatment chamber 3. The exhaust pipe 10 discharges the treated gas, and the support legs 9 support the ultraviolet treatment chamber 3 so that the ultraviolet treatment chamber 3 can be placed stably on a flat surface.

[0025] Furthermore, the front end of the machine body 1 is hinged with an opening and closing door 2. The opening and closing door 2 can seal the machine body, keeping it in a relatively sealed state during operation and reducing the risk of ozone leakage. When feeding or maintaining the equipment, the opening and closing door 2 can be opened to open the front end of the machine body 1 for easy operation.

[0026] Furthermore, a connecting pipe 4 extends from one end of the filter cartridge 17, and a cap 18 is threadedly connected to the extended end of the filter cartridge 17. An activated carbon filter element is inserted inside the filter cartridge 17. The activated carbon filter element has a columnar structure. After the filter element is installed, the cap 18 is installed on the extended end of the filter cartridge 17 to keep the filter cartridge 17 in a sealed state and prevent the leakage of ozone-carrying gas.

[0027] Furthermore, the top and bottom of the flow guide 16 are provided with openings, and the top and bottom of the filter cartridge 17 are provided with air permeable sections 15 near the openings of the flow guide 16. When the exhaust fan 14 is running, the connecting pipe 4 will draw air, and the gas carrying ozone will come into contact with the filter cartridge through the flow guide 16 and the air permeable section 15, and be adsorbed by the filter cartridge.

[0028] The usage method of this embodiment is as follows: Corona treatment machines are typically used for surface treatment of materials, such as plastic films. They generate corona through high-voltage discharge, increasing surface tension. During operation, the machine body 1 also generates heat, which rises into the cooling box 5. The hot air first contacts the heat sink 7, which has a circulation pipe 6 at its top. The circulation pipe 6 circulates a low-temperature liquid through a circulating water tank 8, cooling the hot air and preventing overheating of internal components and short circuits. During operation, the machine body 1 generates ozone. At this time, the exhaust fan 14, through the bottom of the connecting pipe 4, generates ozone. The cooling box 5 is evacuated to create negative pressure at the top of the unit 1, drawing the flue gas generated during operation into the connecting pipe 4. The flue gas passes through the filter core 17 and comes into full contact with the activated carbon filter. The porous structure of the activated carbon adsorbs ozone and catalytically decomposes it into oxygen. The treated flue gas is then transported through the exhaust plate 13 into the ultraviolet treatment box 3. The ultraviolet lamp 11 releases ultraviolet light, which absorbs the energy and decomposes into oxygen. The free oxygen atoms then combine with the undecomposed ozone to further generate oxygen, thus removing ozone from the flue gas.

[0029] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model 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.
