Description

Technical Field

[0001] This utility model relates to an ozone collection and decomposition device for an integrated 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).

[0004] The oxygen atoms (O) produced by ionization react with surrounding oxygen molecules (O2) to generate ozone (O3). Since the air exchange in production workshops is far from meeting the needs for ozone diffusion, ozone that cannot be decomposed and diffused in time, when reaching a certain concentration, may harm the environment and human health. Therefore, appropriate measures need to be taken to recover and treat the ozone released by the corona discharge machine.

[0005] Existing ozone collection and treatment devices are generally suitable for collecting ozone from a single corona discharge machine. However, in production workshops, the locations of corona discharge machines are often predetermined before production begins, and these machines are arranged quite densely. Since ozone collection and treatment devices are considered post-production environmental improvement equipment, and no space was initially reserved for such devices, modifying the surrounding area of ​​each machine to accommodate them would be a waste of significant manpower and resources. Therefore, ozone generated by multiple corona discharge machines requires centralized collection and treatment. Utility Model Content

[0006] 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.

[0007] The technical solution provided by this utility model is as follows: An integrated ozone collection and decomposition device for blown film corona machine, including a corona treatment machine, an ozone decomposition box, a fan and a conveying pipeline, wherein the conveying pipeline connects the corona treatment machine, the fan and the ozone decomposition box in sequence.

[0008] The delivery pipeline includes a collection pipeline and an air intake pipeline. There are multiple corona treatment machines, and each corona treatment machine is connected to the collection pipeline through an air intake pipeline. A valve is installed on the air intake pipeline.

[0009] Compared with the prior art, the technical solution provided by this utility model has the following beneficial effects: the ozone generated by the corona treatment machine during operation is introduced into the ozone decomposition chamber through the air inlet pipe and the collection pipe under the pressure of the fan; there are multiple corona treatment machines, which are connected through the air inlet pipe and the collection pipe respectively. The distance between each corona treatment machine and the fan is different, so the suction at the air inlet pipe of different corona treatment machines is different. A valve is set on the air inlet pipe, and the air speed is adjusted by controlling the valve to change the size of the air outlet of the air inlet pipe, thereby balancing the air supply of different corona treatment machines, so that the ozone generated by the equipment far away from the fan can also be sent into the ozone reaction equipment.

[0010] Based on the above technical solution, the present invention can be further improved as follows.

[0011] Preferably, the fan is connected to the control box.

[0012] The beneficial effect of adopting the above-mentioned further solution is that the control box is used to adjust the power of the fan. When the corona treatment units in different positions are working, the power of the fan is adjusted according to the distance from the fan so that there is enough suction to draw ozone into the air inlet duct.

[0013] Preferably, the diameter of the collection pipe is larger than that of the air intake pipe.

[0014] The beneficial effect of adopting the above-mentioned further solution is that the ozone in multiple air intake pipes is collected in the collection pipe and then compressed into the ozone decomposition chamber.

[0015] Preferably, the corona treatment machine is equipped with a housing, the housing cover is hinged to the housing, and the support block is located on the side of the housing.

[0016] Preferably, when the corona treatment machine is working, the support block supports the box cover, leaving a gap between the box cover and the box body.

[0017] The beneficial effect of adopting the above-mentioned further solution is that when the corona treatment machine is working, the support block supports the cover and the body of the box with a gap, allowing the plastic film that needs to be corona treated to pass through, and the plastic film does not come into contact with the body and the cover, minimizing the ozone from escaping from the box and volatilizing into the air, while also serving as a dustproof function; when the corona treatment machine is not working, the cover can be closed for dust prevention.

[0018] Preferably, the air intake pipe extends through the housing to the top of the corona treatment machine, and the end of the air intake pipe is provided with an air inlet.

[0019] An air inlet is installed above the corona treatment machine. The generated ozone enters through the air inlet and is compressed into the ozone decomposition chamber for decomposition.

[0020] Preferably, a gas flow rate sensor is installed on the air inlet.

[0021] The valve can regulate the gas flow rate, and the gas flow rate can be monitored by the gas flow rate sensor to ensure that the ozone generated by the corona treatment machine can be completely drawn into the air inlet. When multiple corona treatment machines are working at the same time, it is convenient to monitor the ozone absorption of each device.

[0022] Preferably, the ozone decomposition chamber contains an ozone decomposition catalyst to decompose the ozone gas in the chamber into oxygen.

[0023] Preferably, a temperature alarm device and a pressure alarm device are installed between the fan and the ozone decomposition box to ensure the normal operation of the equipment and to promptly alarm in case of abnormality. Attached Figure Description

[0027] 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.

[0028] like Figures 1-2As shown, an integrated ozone collection and decomposition device for blown film corona machines includes a corona treatment machine 4, an ozone decomposition chamber 1, a fan 2, and a conveying pipeline. The conveying pipeline connects the corona treatment machine 4, the fan 2, and the ozone decomposition chamber 1 in sequence. The conveying pipeline includes a collection pipeline 6 and an air inlet pipeline 7. There are multiple corona treatment machines 4, and each corona treatment machine 4 is connected to the collection pipeline 6 through the air inlet pipeline 7. The diameter of the collection pipeline 6 is larger than that of the air inlet pipeline 7. A valve 5 is installed on the air inlet pipeline 7, and the fan 2 is connected to a control box 3. During operation, the corona treatment machine generates ozone. Under the pressure of the fan 2, the ozone is forced into the intake pipe 7. Ozone generated by multiple corona treatment machines 4 enters the collection pipe 6 through the intake pipe 7. Specifically, because the collection pipe 6 needs to handle the total flow of multiple corona treatment machines 4, its diameter is larger than that of the intake pipe 7 to ensure that the flow requirements of the entire system are met. Under the action of the fan 2, the ozone enters the ozone decomposition chamber 1 through the collection pipe 6. Since the distance between each corona treatment machine 4 and the fan 2 varies, the suction force at the intake pipe 7 of each corona treatment machine 4 is different. The power of the fan 2 is adjusted by the control box 3, and the air speed is adjusted by the valve 5, ensuring that the working corona treatment machine 4, regardless of its distance from the fan, has sufficient suction force to force the ozone into the ozone decomposition chamber 1. The ozone decomposition chamber 1 contains an ozone decomposition catalyst, which decomposes the ozone gas in the chamber into oxygen, which is then released into the workshop to participate in air circulation and increase the oxygen content.

[0029] Specifically, the corona treatment machine 4 is equipped with a housing 8, with a cover 9 hinged to the housing 8, and a support block 10 located on the side of the housing 8. When the corona treatment machine 4 is working, the support block 10 supports the cover 9, leaving a gap between the cover 9 and the housing 8. The air intake pipe 7 extends through the housing 8 to the top of the corona treatment machine 4, and an air intake port is provided at the end of the air intake pipe 7.

[0030] When the corona treatment machine is working, the support block 10 supports the cover 9 without closing, which allows the cover 9 to be fixed relative to the body 8 with a certain gap. This gap allows the plastic film to be corona treated to pass through, and the upper and lower surfaces of the plastic film do not contact the body and the cover. Closing the body as much as possible can minimize the escape of ozone from the body and volatilize into the air, while also preventing dust. When the corona treatment machine is not working, since the support block is movable, the cover can be closed for dust prevention by removing the support block or adjusting its position.

[0031] More specifically, a gas flow rate sensor is installed on the air inlet. The valve can regulate the gas flow rate, and the gas flow rate sensor monitors the gas flow rate to ensure that the ozone generated by the corona treatment machine can be completely drawn into the air inlet. When multiple corona treatment machines are working simultaneously, it is convenient to monitor the ozone absorption of each device.

[0032] Temperature alarm devices and pressure alarm devices are installed between fan 2 and ozone decomposition box 1 to ensure normal operation of the equipment and to promptly alarm in case of abnormality.

[0033] 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.
