Description

Technical Field

[0001] This utility model relates to an ozone collection and decomposition device for a single-unit blown film corona machine, belonging to the technical field of ozone collection and decomposition devices. Background Technology

[0002] Corona treatment machines, also known as corona machines, are mainly used for surface treatment of plastic film or plastic sheet products to facilitate operations such as ink printing, lamination, blown film, coating, bonding, material modification, grafting, polymerization, film deposition, casting, and pasting.

[0003] The working principle of a corona discharge machine is to use high voltage to generate low-temperature plasma through corona discharge on the surface of the plastic being treated, causing a free radical reaction on the plastic surface and leading to polymer cross-linking. When a high voltage is applied between the electrodes of the corona discharge machine, a corona discharge phenomenon occurs. Corona discharge is a type of partial discharge, mainly occurring in the gas near the electrodes. During corona discharge, high-energy electrons collide with oxygen molecules in the air, ionizing the oxygen molecules. During ionization, oxygen molecules (O2) are decomposed into oxygen atoms (O). The ionized oxygen atoms (O) react with surrounding oxygen molecules (O2) to generate ozone (O3). Since the air exchange in production workshops is far from meeting the needs of ozone diffusion, when ozone that cannot be decomposed and diffused reaches a certain concentration, it may cause harm to the environment and human health. Therefore, appropriate measures need to be taken to recover and treat the ozone released by the corona discharge machine. Utility Model Content

[0004] The purpose of this utility model is to provide a new technical solution to improve or solve the technical problems existing in the prior art as described above.

[0005] The technical solution provided by this utility model is as follows: an ozone collection and decomposition device for a single blown film corona machine, including a corona treatment machine, a fan and an ozone decomposition box, and a power supply unit, wherein the power supply unit supplies power to both the corona treatment machine and the fan.

[0006] The fan is connected to the corona treatment machine through an air inlet pipe, and the ozone decomposition box is connected to the fan through an air outlet pipe.

[0007] The ozone decomposition chamber includes a lid and a body. A first support plate and a second support plate are respectively arranged parallel to the bottom surface of the body inside the chamber. An isolation plate is arranged on the side of the first and second support plates near the lid. The isolation plate, the first support plate, and the second support plate form a closed space inside the chamber. The closed space contains a catalyst for catalyzing the decomposition of ozone.

[0008] The first support plate is covered with a cotton pad;

[0009] The upper surface of the box is provided with an exhaust hole.

[0010] The technical solution provided by this utility model has the following advantages compared with the prior art:

[0011] During operation, the ozone generated by the corona treatment machine is drawn into the ozone decomposition chamber through the inlet and outlet pipes under the pressure of the fan. Inside the chamber, the ozone first enters the enclosed space via the second support plate, which contains a catalyst. The ozone is decomposed under the action of the catalyst, and the resulting oxygen is filtered by a cotton pad above the second support plate and discharged through the exhaust port, directly entering the production workshop. The cotton pad is used to filter dust generated within the enclosed space, preventing dust from entering the production workshop.

[0012] The isolation plate keeps the space inside the ozone decomposition chamber closed, controlling the reaction environment of the catalyst and ozone and preventing direct contact with the outside world. The isolation plate is also detachably installed on the side of the first and second support plates, making it easy to check the catalyst status and replace the catalyst regularly.

[0013] The power supply unit controls the opening and closing of both the corona treatment unit and the fan. When the corona treatment unit starts working, the fan starts simultaneously. The impeller inside the fan rotates to generate a pressure difference, which compresses ozone into the pipeline and delivers it to the ozone decomposition chamber. When the corona treatment unit stops working, the fan stops simultaneously. There is no need to operate the fan separately, which saves electricity and simplifies the operation process.

[0014] Based on the above technical solution, the present invention can be further improved as follows.

[0015] Preferably, an air inlet is provided between the air intake pipe and the corona treatment machine, and the air inlet is shaped like a trumpet with its opening facing the corona treatment machine.

[0016] The beneficial effect of adopting the above-mentioned further solution is that the horn-shaped air inlet increases the contact area with the electrodes of the corona treatment machine, which can absorb ozone generated around the electrodes more widely, effectively guide the airflow into the slender pipe, reduce airflow eddies and resistance, and help improve the flow efficiency of the gas.

[0017] Preferably, the ozone decomposition chamber has holes, and a pipe connection port is provided on the outside of the holes. The gas outlet pipe is sleeved on the pipe connection port to form a gas channel.

[0018] The advantage of adopting the above-mentioned further solution is that the gas outlet pipe and the ozone decomposition box are designed separately, which makes it easy to disassemble if any parts need to be replaced.

[0019] Preferably, the pipe connection is fixed to the outer surface of the box cover by screws.

[0020] Preferably, a sieve plate is fixed on the inner wall of the box cover to cover the holes.

[0021] The beneficial effect of adopting the above-mentioned further solution is to prevent large particulate dust from entering the ozone decomposition chamber.

[0022] Preferably, the first support plate is provided with grid holes.

[0023] The beneficial effect of adopting the above-mentioned further solution is that it supports the cotton pad while allowing gas to pass through the support plate, be filtered by the cotton pad, and then be discharged through the exhaust hole.

[0024] Preferably, the lid is provided with a buckle, and the lid and the box body are connected by the buckle.

[0025] The beneficial effects of adopting the above-mentioned further solution are that the ozone decomposition chamber is closed by a snap-lock mechanism, which improves the aesthetics of the ozone decomposition chamber. When it is necessary to check or replace the catalyst, the chamber cover and the isolation plate are opened to replace the catalyst. The double protection isolates the external gas and can better ensure the reaction environment of ozone. Attached Figure Description

[0033] The principles and features of this utility model are described below with reference to examples. The examples are only used to explain this utility model and are not intended to limit the scope of this utility model.

[0034] like Figures 1-6 As shown, an ozone collection and decomposition device for a single-unit blown film corona machine includes a corona treatment machine 1, a fan 2, an ozone decomposition chamber 3, and a power supply unit (not shown). The power supply unit supplies power to both the corona treatment machine 1 and the fan 2. When the corona treatment machine 1 starts working, the fan 2 starts simultaneously, pressurizing ozone into the pipeline and delivering it to the ozone decomposition chamber 3. When the corona treatment machine 1 stops working, the fan 2 stops simultaneously. The fan 2 is connected to the corona treatment machine 1 through an air inlet pipe 5. A funnel-shaped air inlet 6 is provided between the air inlet pipe 5 and the corona treatment machine 1, which can more effectively absorb ozone. The ozone at the electrode of the ozone treatment machine 1 is guided into the air intake pipe 5; the ozone decomposition box 3 is connected to the fan 2 through the air outlet pipe 4; the ozone decomposition box 3 has holes, and the outside of the holes is provided with pipe connection ports 15. The pipe connection ports 15 are fixed to the outer surface of the box cover 7 with screws. The air outlet pipe 4 is sleeved on the pipe connection ports 15 to form a closed gas channel. The ozone is then compressed by the fan 2 and enters the ozone distribution box 3 through the air outlet pipe 4. The inner wall of the box cover 7 is fixed with a sieve plate 12 that can cover the holes to prevent large dust particles from entering the ozone decomposition box 3.

[0035] The ozone decomposition chamber 3 includes a cover 7 and a body 8. A first support plate 10 and a second support plate 14 are respectively arranged parallel to the bottom surface of the body 8. An isolation plate 11 is arranged on the side of the first support plate 10 and the second support plate 14 near the cover 7. The isolation plate 11, the first support plate 10 and the second support plate 14 form a closed space in the body 8. The closed space is filled with a catalyst for catalyzing ozone decomposition. The first support plate 10 is provided with grid holes and is covered with a cotton pad. An exhaust hole 13 is opened on the upper surface of the body 8.

[0036] Ozone first enters the closed space through the second support plate 14. Under the action of the catalyst, the ozone is decomposed, and the generated oxygen passes through the second support plate 14 with grid holes. After being filtered by the cotton pad above the second support plate 14, it is discharged into the production workshop through the exhaust port 13.

[0037] The lid 7 is equipped with a buckle 9, and the lid 7 and the body 8 are connected by the buckle 9. When in use, the lid 7 is closed. If it is necessary to check or replace the catalyst, the ozone decomposition chamber 3 is opened through the buckle 9, and the isolation plate 11 is opened to replace the catalyst. The double protection of the lid 7 and the isolation plate 11 helps to isolate external gases and ensure a stable ozone reaction environment.

[0038] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
