Description

Technical Field

[0001] This utility model relates to the technical field of intelligent sintering equipment for spark plugs, specifically to an intelligent sintering equipment for spark plug ceramic insulators based on waste heat recovery. Background Technology

[0002] Sintering equipment is a large system mainly used in industries such as metallurgy, mining, ceramics, and powder metallurgy. Its core purpose is to heat powder or fine particulate materials at high temperatures but below their melting points, and transform them into dense, strong polycrystalline materials or products with certain properties through solid-phase diffusion and bonding between particles.

[0003] Chinese utility model patent CN221724909U discloses a sintering device, including a first furnace body, a second furnace body, and a sintering apparatus. The first furnace body includes a first cavity for placing the second furnace body, and the second furnace body includes a second cavity for placing the sintering apparatus. First vent holes are provided at both ends of the second furnace body along its length, and the second cavity communicates with the first cavity through the first vent holes. The sintering apparatus includes multiple sintering chambers spaced apart along the height of the sintering apparatus. Multiple second vent holes are provided at both ends of the sintering apparatus to connect the sintering chambers with the second cavity. This utility model, through multiple second vent holes, allows multiple sintering chambers to communicate with the second cavity, reducing the differences in protective atmosphere and / or heat within the multiple sintering chambers, minimizing the differences in size and properties of the sintered bodies after sintering in different sintering chambers, and thus improving the sintering precision.

[0004] This invention improves the precision of sintering. However, existing sintering equipment does not have waste heat recovery capabilities. Sintering is one of the most energy-intensive processes in the steel industry, and its exhaust gas has a high temperature. This high-temperature exhaust gas carries a large amount of heat energy. If it is not recovered, it is equivalent to directly releasing the heat generated by fuel combustion into the atmosphere, resulting in extremely low energy utilization efficiency. Therefore, an intelligent sintering equipment for spark plug ceramic insulators based on waste heat recovery is proposed to solve the problems mentioned above. Utility Model Content

[0005] To address the shortcomings of existing technologies, this invention provides an intelligent sintering device for spark plug ceramic insulators based on waste heat recovery, which has advantages such as high-temperature waste gas temperature recovery and waste gas dust filtration, thus solving the problems mentioned in the background technology.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A smart sintering device for spark plug ceramic insulators based on waste heat recovery includes a sintering device body and a recovery box. The recovery box is equipped with a high-temperature waste gas temperature recovery and waste gas dust filtration component. The recycling and filtration assembly includes an exhaust gas pipe on the left side of the recycling box, a heat-conducting plate fixedly connected to the inside of the recycling box, a water tank fixedly connected to the top of the heat-conducting plate, a filter box fixedly connected to the bottom of the recycling box, a gas delivery pipe fixedly connected to the right side of the recycling box, a guide rail fixedly connected to the inside of the filter box, a filter frame fixedly connected to the inside of the guide rail, and a filter screen fixedly connected to the inside of the filter frame.

[0007] Furthermore, the exhaust gas pipeline is connected to the sintering equipment body, and an electromagnetic valve is fixedly connected to the outside of the exhaust gas pipeline.

[0014] Compared with the prior art, this utility model provides an intelligent sintering device for spark plug ceramic insulators based on waste heat recovery, which has the following beneficial effects: 1. This intelligent sintering equipment for spark plug ceramic insulators based on waste heat recovery incorporates a recovery filtration component. High-temperature exhaust gas generated by the sintering equipment is transported to the inside of the recovery tank via an exhaust gas pipeline.

Furthermore, the exhaust gas, after heat transfer, is input into a filter box via a gas delivery pipe. It is then filtered through a filter screen inside the filter frame before being discharged through an exhaust pipe on the side of the filter box, preventing exhaust gas from polluting the working environment.

[0015] 2. This intelligent sintering equipment for spark plug ceramic insulators based on waste heat recovery can control the opening and closing of the exhaust gas pipeline and the conveying gas pipeline by setting solenoid valves and safety valves, thereby controlling and maintaining the gas pressure inside the recovery box and avoiding excessively high or low gas pressure.

The high-temperature waste gas generated by the sintering device body 1 is transported to the interior of the recovery tank 2 via the waste gas pipe 3. Under the action of the heat-conducting plate 5, the heat is transferred to the water tank 6 to heat the water inside the water tank 6, generating hot water and steam, which are then converted into usable energy, thereby reducing the energy consumption of the entire sintering process.

[0020] In addition, the exhaust gas after heat transfer will be input into the filter box 7 through the air delivery pipe 8, and then filtered through the filter screen 12 inside the filter frame 11 before being discharged through the exhaust pipe on the side of the filter box 7, so as to avoid exhaust gas from polluting the working environment.

[0021] In this embodiment, the exhaust gas pipeline 3 is connected to the sintering equipment body 1, and a solenoid valve 4 is fixedly connected to the outside of the exhaust gas pipeline 3. The conveying gas pipe 8 is connected to the filter box 7, and a safety valve 9 is fixedly connected to the outside of the conveying gas pipe 8. By setting the solenoid valve 4 and the safety valve 9, the opening and closing of the exhaust gas pipeline 3 and the conveying gas pipe 8 can be controlled, thereby controlling and maintaining the gas pressure inside the recovery box 2 and avoiding the situation of excessively high or low gas pressure.

[0022] It should be noted that a water supply pipe 13 is fixedly connected to the top of the water tank 6, and a sealing cap is threaded to the top of the water supply pipe 13. The water supply pipe 13 allows staff to easily replenish water to the inside of the water tank 6.

[0026] It should be noted that the sealed door 16 is fixedly connected to the outside with a door handle, and both the sealed door 16 and the sealed baffle 17 are covered with sealing strips 18.

[0027] The working principle of the above embodiments is as follows: During use, the high-temperature exhaust gas generated by the sintering equipment body 1 is transported to the inside of the recovery box 2 through the exhaust gas pipe 3. Under the action of the heat conduction plate 5, the heat is transferred to the water tank 6 to heat the water inside the water tank 6, producing hot water and steam, which are converted into useful energy, thereby reducing the energy consumption of the entire sintering process. After the heat is transferred, the exhaust gas is input into the filter box 7 through the conveying gas pipe 8. Then, the exhaust gas is filtered through the filter screen 12 inside the filter frame 11 and discharged through the exhaust pipe on the side of the filter box 7 to avoid exhaust gas pollution of the working environment. The solenoid valve 4 and the safety valve 9 can control the opening and closing of the exhaust gas pipe 3 and the conveying gas pipe 8, thereby controlling and maintaining the gas pressure inside the recovery box 2 and avoiding excessively high or low gas pressure.
