Description

Technical Field

[0001] The utility model relates to the technical field of PTC heaters, in particular to an oven for PTC heater production. Background Technique

[0002] As a core component in modern electronic industry, the baking process in the production of PTC heaters is a key step to ensure product quality and performance. Special ovens for PTC heater production integrate advanced temperature control technology and thermal circulation systems. These ovens not only improve production efficiency, but also realize real-time monitoring and adjustment of the baking process through an intelligent management system, further ensuring product stability and consistency.

[0003] However, during the baking process, due to high-temperature reactions of materials and possible decomposition of additives, a series of harmful gases or odors will be generated. The components of these waste gases are complex and challenging to handle. Some ovens lack a dedicated waste gas treatment system. Although some ovens have installed simple waste gas treatment devices, these devices often adopt basic treatment technologies such as simple filtration or adsorption. The treatment effects of these methods are limited and it is difficult to effectively remove harmful substances in the waste gas, resulting in the direct discharge of harmful gases and odors generated during the baking process into the production environment, which not only pollutes the air, but may also damage the respiratory systems of workers, having certain deficiencies. Summary of the Utility Model

[0004] The problem to be solved by the utility model is to provide an oven for PTC heater production that can effectively treat harmful gases and odors generated during the baking process.

[0005] To solve the above technical problems, the technical solution adopted by the utility model is: an oven for PTC heater production, including an oven body. An observation window is arranged on the front side of the oven body. A sealing plate is arranged on each of the left and right sides of the oven body.

A treatment mechanism is arranged above the oven body. The gas collection mechanism includes an air extraction pump, and the air extraction pump is fixedly installed on the top of the oven body. An air delivery pipe is fixedly communicated inside the air extraction pump.

[0006] The processing mechanism includes a processing box fixedly connected to the top of the baking furnace body, and the inside of the processing box is fixedly communicated with the end of the air supply pipe away from the air extraction pump. The top of the processing box is fixedly communicated with an exhaust pipe. The inner wall of the processing box is slidably connected with a mounting plate. The outer surface of the mounting plate is fixedly connected with a metal mesh, and the outer surface of the metal mesh is in contact with the inner wall of the baking furnace body. The inner wall of the processing box is slidably connected with a limiting frame, and an activated carbon plate is placed inside the limiting frame. The outer surface of the processing box is fixedly installed with a catalytic combustor, and the output end of the catalytic combustor penetrates into the inside of the processing box.

[0007] Preferably, in a baking furnace for PTC heater production, a gas collecting pipe is fixedly communicated inside the air extraction pump, and the gas collecting pipe penetrates through the outer surface of the baking furnace body and extends into the inside of the baking furnace body. The end of the gas collecting pipe away from the air extraction pump is fixedly communicated with a gas collecting hopper, and the outer surface of the gas collecting hopper is fixedly connected to the inner wall of the baking furnace body.

[0008] The advantages and beneficial effects of the present utility model are as follows: By setting up a gas collecting mechanism, the waste gas generated during the baking process of the PTC heater inside the baking furnace body can be centrally collected.

[0018] A conveyor belt 5 is fixedly installed inside the baking oven body 1.

[0019] An air collection mechanism 6 is arranged above the baking oven body 1.

[0020] The air collection mechanism 6 includes an air extraction pump 601, and the air extraction pump 601 is fixedly installed on the top of the baking oven body 1. A delivery pipe 604 is fixedly communicated inside the air extraction pump 601.

[0021] A collection pipe 602 is fixedly communicated inside the air extraction pump 601. The collection pipe 602 penetrates through the outer surface of the baking oven body 1 and extends into the baking oven body 1. One end of the collection pipe 602 away from the air extraction pump 601 is fixedly communicated with a collection hopper 603, and the outer surface of the collection hopper 603 is fixedly connected to the inner wall of the baking oven body 1.

[0022] The collection hopper 603 is designed in a funnel shape, narrow at the top and wide at the bottom, capable of centrally collecting the waste gas generated during the baking process, improving the waste gas collection efficiency.

[0023] A treatment mechanism 7 is arranged above the baking oven body 1.

[0024] The treatment mechanism 7 includes a treatment box 701 fixedly connected to the top of the baking oven body 1. The inside of the treatment box 701 is fixedly communicated with one end of the delivery pipe 604 away from the air extraction pump 601. An exhaust pipe 707 is fixedly communicated with the top of the treatment box 701.

[0025] An installation plate 702 is slidably connected to the inner wall of the treatment box 701.

[0026] A gasket is provided on the outer surface of the mounting plate 702, which can effectively prevent the leakage of gas inside the treatment box 701. At the same time, a handle is provided on the outer surface of the mounting plate 702. By pulling the handle, the mounting plate 702 and the metal mesh 703 can be withdrawn from the treatment box 701, and then the metal mesh 703 can be cleaned.

[0027] The outer surface of the mounting plate 702 is fixedly connected to a metal mesh 703, and the outer surface of the metal mesh 703 is in contact with the inner wall of the baking furnace body 1.

[0028] The metal mesh 703 can perform primary filtration on the waste gas, remove large particles and soot in the waste gas, and protect the subsequent treatment equipment from wear.

[0029] A limiting frame 704 is slidably connected to the inner wall of the treatment box 701.

[0030] A gasket is provided on the outer surface of the limiting frame 704, which can effectively prevent the leakage of gas inside the treatment box 701. At the same time, a handle is provided on the outer surface of the limiting frame 704. By pulling the handle, the limiting frame 704 and the activated carbon plate 705 can be withdrawn from the treatment box 701, and then the activated carbon plate 705 can be replaced.

[0031] An activated carbon plate 705 is placed inside the limiting frame 704.

[0032] The waste gas will come into full contact with the activated carbon plate 705. The activated carbon plate 705 can adsorb organic substances and other harmful gases in the waste gas by virtue of its developed pore structure.

[0035] Working principle: When the utility model is in use, the PTC heater to be baked can be sent into the interior of the baking furnace body 1 through the conveyor belt 5, and then the interior of the baking furnace body 1 is sealed through the sealing plate 3. At this time, the heating element inside the baking furnace body 1 is controlled by the controller 4 to work, and the heat generated by the heating element can bake the PTC heater. During the baking process, the air extraction pump 601 and the catalytic combustor 706 need to be turned on. The waste gas generated during the baking process will be centrally collected through the air collecting hopper 603, and then the waste gas collected by the air collecting hopper 603 is extracted through the air collecting pipe 602, and finally sent into the interior of the treatment box 701 through the air supply pipe 604. At this time, the metal mesh 703 can perform primary filtration on the waste gas, removing large particles and soot in the waste gas and protecting the subsequent treatment equipment from wear. Then the waste gas will come into full contact with the activated carbon plate 705. The activated carbon plate 705 can adsorb organic substances and other harmful gases in the waste gas by virtue of its developed pore structure. Then, the catalytic combustor 706 can fully burn the combustible components in the waste gas, converting them into harmless carbon dioxide and water vapor. Finally, the treated waste gas will be discharged through the exhaust pipe 707. Through the mutual cooperation of the air collecting mechanism 6 and the treatment mechanism 7, the harmful substances in the waste gas can be effectively removed, not only avoiding air pollution, but also effectively protecting the physical health of workers.
