Description

Technical Field

[0001] The utility model relates to the technical field of copper-clad ceramic substrate production, in particular to an environmentally friendly copper-clad ceramic substrate oxidation furnace. Background Art

[0002] The oxidation of copper-clad ceramic substrates plays a vital role in the field of electronics. Simply put, copper-clad ceramics are a thin layer of copper covered on the surface of ceramics, and this layer of copper is oxidized by some method. Doing so can bring some very useful effects. The oxidation of copper-clad ceramic substrates can improve conductivity and heat resistance, and can also enhance the corrosion resistance and mechanical strength of the material. The oxidized copper layer can effectively resist the erosion of some chemical substances. At the same time, it can also enhance the hardness and wear resistance of the material, making the copper-clad ceramic substrate more durable during use.

[0003] During the oxidation process of copper-clad ceramic substrates, some harmful gases and waste gases may be generated. These waste gases mainly come from chemical reactions and material decomposition during the oxidation process, and may specifically include: oxidation waste gases, such as carbon dioxide, oxygen, etc. These gases are usually products of normal oxidation processes and have little impact on the environment. Some volatile organic compounds are also included. During the oxidation process, some volatile organic substances may evaporate from the substrate or coating, such as organic solvents, resin components, etc. These compounds may have a negative impact on the environment and human health. The main waste gases are nitrogen oxides such as nitrogen monoxide and nitrogen dioxide. These nitrogen oxides are common atmospheric pollutants that are harmful to the environment and health. The main waste gases also include carbon monoxide.

[0004] In order to reduce the impact of these harmful gases on the environment and health, it is necessary to invent an environmentally friendly oxidation equipment equipped with an exhaust gas treatment device to reduce the emission of harmful gases. At the same time, by controlling the temperature, gas flow rate and time of the oxidation process, the generation of harmful gases can be minimized, and the emission of harmful gases generated during the oxidation process of copper-clad ceramics can be reduced to protect the environment and human health.

[0043] Principle and operation process

[0044] The utility model controls the flow rate of the airflow entering the furnace body 1, controls the temperature and the oxidation time to achieve the effect of reducing the generation of harmful gases, and at the same time cooperates with activated carbon adsorption to process the small amount of harmful gases generated to achieve the purpose of environmental protection.

[0045] The gas flow rate is controlled by an air volume valve 4 arranged between the air inlet pipe 5 and the furnace body 1. The air volume valve 4 includes a casing 45, an active rod 42, a driven rod 421 and a connecting rod 43. The active rod 42 and the driven rod 421 are rotatably connected to the casing 45 through a rotating bearing. The active rod 42 and the driven rod 421 are both connected with fan blades 44. The active rod 42 and the driven rod 421 are connected by a connecting rod 43. A limiting groove 422 is arranged on the active rod 42, and a limiting column 423 is arranged at a position corresponding to the limiting groove 422 on the casing 45. The active rod 42 is rotatably connected to the output end of the electric cylinder 41. The setting of the limiting groove 422 and the limiting column 423 can prevent the fan blades 44 from being fully opened when the electric cylinder 41 fails, the air intake volume increases, and the amount of harmful gas generated inside also increases. The rotation of the fan blades 44 can be achieved by pushing and pulling the electric cylinder 41 to achieve the effect of controlling the flow rate.

[0046] The temperature is controlled by using a temperature sensor 6 to monitor the temperature in the furnace body 1 in real time, and the controller controls the power of the power connected to the heating wire 101 to achieve the purpose of temperature control. By controlling the temperature and the air intake and reasonably controlling the reaction time, a moderate oxidation reaction can be achieved and the generation of harmful gases can be reduced.

[0047] When in use, first open the furnace cover 3, put the copper-clad ceramic substrate in, and in order to make the surface of the copper-clad ceramic substrate fully contact with the air, a special grid can be added inside the furnace body 1. After putting it in, close the furnace cover 3, screw the clamping bolt 32, and screw it into the threaded hole on the furnace cover 3 until the fixing ring 321 is pressed on the bolt seat 31, start the heating wire 101, start heating, and control the power through the internal temperature of the furnace body 1 detected by the temperature sensor 6, so that the temperature inside the furnace body 1 is at the optimal reaction temperature, and start the electric cylinder 41 to control the air intake. After the airflow flows out from the outlet pipe 7, due to the action of the one-way valve 71, it will not cause backflow.

[0048] The gas enters the filter box 8 through the outlet pipe 7. The filter box 8 is provided with multiple rows of activated carbon boxes 9. The activated carbon boxes 9 are slidably connected to the sliding grooves 91 inside the filter box 8. The filter box 8 is also provided with a box door 81, which makes it easy to take out and replace. An exhaust pipe 12 is provided at the end of the filter box 8 away from the furnace body 1. The exhaust pipe 12 can be connected to the factory exhaust system. The filter box 8 is installed with nitrogen oxide sensors 10 and carbon monoxide sensors 11 on both sides of the opening of the exhaust pipe 12, which can monitor in real time whether the gas after the last stage of filtration of the activated carbon box 9 still contains harmful gases. If harmful gases are detected, it means that the activated carbon in the activated carbon box 9 is inactivated, and the box door 81 needs to be opened for replacement.

[0049] Although the specific implementation methods of the utility model are described above in conjunction with the accompanying drawings, it is not intended to limit the scope of protection of the utility model. On the basis of the technical solution of the utility model, various modifications or deformations that can be made by technical personnel in this field without creative work are still within the scope of protection of the utility model.
