Description

Technical Field

[0001] The utility model relates to the technical field of heating furnaces, in particular to an external structure of a furnace shell of a high-temperature furnace. Background Art

[0002] High-temperature furnaces, widely used in industrial production and scientific research, play a vital role in numerous industries, including materials processing, metallurgy, chemicals, and electronics. They provide a high-temperature environment for the processing and chemical reactions of various materials, enabling key processes such as sintering, melting, heat treatment, and chemical synthesis. The performance and quality of high-temperature furnaces directly impact product quality, production efficiency, and the accuracy and reliability of scientific research experiments.

[0003] The connection method between the furnace door and the furnace body of traditional high-temperature furnaces is often relatively simple, lacking an effective sealing structure design. The existing furnace door is only connected to the furnace body by a simple hinge. When closed, the gap between the furnace door and the furnace body is large, making it difficult to achieve a tight seal. In a high-temperature environment, due to the thermal expansion and deformation of the material, this gap will further increase, causing gas leakage in the furnace, affecting the temperature, pressure and atmosphere stability in the furnace, and thus adversely affecting product quality. Although some high-temperature furnaces have adopted some sealing measures, such as installing rubber sealing strips around the furnace door, these sealing strips are prone to aging, hardening, and losing elasticity at high temperatures, thereby reducing the sealing effect. Moreover, with the extension of the use time, the sealing strips are prone to wear and damage, and need to be replaced frequently, which increases maintenance costs and downtime. Therefore, a high-temperature furnace shell shape structure is proposed.

[0004] In view of this, the present invention is proposed to solve the above technical problems. Utility Model Content

[0005] In order to achieve the above object, the present invention is implemented through the following technical solutions:

[0006] A high-temperature furnace shell structure includes a furnace body, a door frame and a furnace door. A feed port is provided at one end of the furnace body, and the door frame and furnace door are arranged on the side close to the feed port. A drive motor is installed on the top of the door frame, and limit blocks are symmetrically provided on both sides of the door frame. The furnace door is clamped inside the two limit blocks, and an electromagnetic device is provided at the bottom of the door frame.

[0007] More preferably, the width of the furnace door is equal to the distance between the two limiting blocks, and an elastic sealing strip is provided inside the limiting block.

[0008] Further preferably, the power output end of the drive motor and the top of the furnace door are connected by a chain.

[0009] Further preferably, a heating chamber is provided inside the furnace body, a furnace lining is provided inside the heating chamber, and a high-temperature curing agent is sprayed on the surface of the furnace lining to form a heat-insulating wall.

[0010] More preferably, a plurality of exhaust valves and pressure sensors are evenly arranged on the top of the furnace body, and the exhaust valves and pressure sensors are signal-connected.

[0011] More preferably, a one-way pressure valve is provided inside the furnace body, and the direction of the one-way pressure valve is from the inside of the furnace body to the outside of the furnace body.

[0012] Compared with the prior art, the present invention has the following advantages: by symmetrically arranging the limit blocks and the furnace door on both sides of the door frame, the furnace door is clamped inside the two limit blocks when closed, and the limit blocks and the furnace door are made of high-temperature resistant metal materials, which are difficult to deform and damage in a high-temperature environment, thereby improving and maintaining good sealing performance. Through the electromagnetic device, when the furnace door is closed into place, the electromagnetic device is energized to generate a strong attraction, so that the furnace door and the furnace body fit tightly, and the adsorption force of the electromagnetic device can be adjusted according to the pressure and temperature of the furnace body, ensuring that good sealing performance can be maintained under different working conditions.

[0018] The following is combined with Figures 1 to 4 The utility model is further introduced in detail.

[0019] A high temperature furnace shell structure, such as Figure 1As shown, it comprises a furnace body 1, a door frame 2 and a furnace door 4. A feed port is provided at one end of the furnace body 1, and the door frame 2 and the furnace door 4 are arranged on the side close to the feed port. A driving motor 3 is installed on the top of the door frame 2, and limit blocks 6 are symmetrically provided on both sides of the door frame 2. The furnace door 4 is clamped inside the two limit blocks 6. Furthermore, the edge positions of the furnace door 4 and the limit blocks 6 are made of high-temperature resistant metal materials. For example, the material is stainless steel or heat-resistant alloy steel. An electromagnetic device 7 is provided at the bottom of the door frame 2.

[0020] By symmetrically arranging the limit blocks 6 and the furnace door 4 on both sides of the door frame 2, the furnace door 4 is clamped in the inside of the two limit blocks 6 when closed, and the limit blocks 6 and the furnace door 4 are made of high-temperature resistant metal materials, which are difficult to deform and damage in a high-temperature environment, thereby improving and maintaining good sealing performance. Through the electromagnetic device 7, when the furnace door 4 is closed in place, the electromagnetic device 7 is energized to generate a strong attraction, so that the furnace door 4 is tightly fitted with the furnace body 1, and the adsorption force of the electromagnetic device 7 can be adjusted according to the pressure and temperature of the furnace body 1, ensuring that good sealing performance can be maintained under different working conditions.

[0021] Furthermore, good sealing performance helps to maintain a stable temperature, pressure and atmosphere environment in the furnace body 1, provides reliable protection for the calcination process of the high-temperature furnace, improves product quality and consistency, reduces scrap rate, and thus improves production efficiency and economic benefits.

[0022] Specifically, the width of the furnace door 4 is equal to the distance between the two limit blocks 6, and an elastic sealing strip is provided inside the limit block 6. Exemplarily, the elastic sealing strip is made of a graphite fiber sealing strip or a ceramic fiber sealing strip. Furthermore, when two limit blocks 6 are inserted into the edge position of the furnace door 4, the elastic sealing strip is compressed, further filling the tiny gap between the furnace door 4 and the limit blocks 6, thereby enhancing the sealing effect and preventing gas leakage.

[0023] Specifically, the power output end of the drive motor 3 and the top of the furnace door 4 are connected by a chain 5. Furthermore, the drive motor 3 is connected to an external power supply and a control panel. When the furnace door 4 is opened, the drive motor 3 drives the furnace door 4 to rise through the chain 5, thereby opening the feed port. When closed, the drive motor 3 drives the furnace door 4 to descend through the chain 5. The furnace door 4 descends and is clamped between the limit blocks 6 by its own weight.

[0024] Specifically, a heating chamber 8 is provided inside the furnace body 1, and a furnace lining is provided inside the heating chamber 8. Furthermore, a high-temperature curing agent is sprayed on the surface of the furnace lining to form an insulating wall, thereby increasing the surface strength and thermal radiation performance of the furnace lining, and further reducing the heat storage loss of the furnace lining, achieving the effect of rapid heating, and maximizing the thermal efficiency of the furnace body 1.

[0025] Specifically, a plurality of exhaust valves 9 and pressure sensors 10 are evenly arranged on the top of the furnace body 1, and the exhaust valves 9 and the pressure sensors 10 are signal-connected. Furthermore, when the calcination is completed, the temperature and pressure of the furnace body 1 rise, and when the threshold of the set exhaust threshold 9 is reached, the pressure sensor 10 sends a signal to the external control system, and the control system automatically opens the exhaust valve 9 to discharge the high-temperature gas in the furnace body 1. Specifically, the exhaust valve 9 is made of high-temperature resistant and corrosion-resistant materials, exemplarily titanium alloy or ceramic material, to ensure long-term stable operation under high temperature and harsh environment.

[0026] Furthermore, multiple exhaust valves 9 and pressure sensors 10 cooperate with each other, reducing the steps and time of manual operation, improving the degree of automation and work efficiency of the production process, reducing labor intensity, and avoiding damage to the sealing structure caused by excessive or insufficient pressure in the furnace body 1, thereby reducing potential safety hazards and ensuring the personal safety of staff and the normal operation of equipment.

[0027] Specifically, a one-way pressure valve 11 is provided inside the furnace body 1, and the direction of the one-way pressure valve 11 is from the inside of the furnace body 1 to the outside of the furnace body 1. Furthermore, during the heating and cooling process of the furnace body 1, the one-way pressure valve 11 adjusts the pressure inside the furnace body 1 to keep the pressure inside the furnace body 1 balanced with the outside pressure, and prevents damage to the limit block 6 or gas leakage due to excessive pressure difference. The one-way pressure valve 11 only allows gas to be discharged from the furnace body 1 to the outside. When the pressure inside the furnace body 1 is lower than the external pressure, the valve automatically closes to prevent external air from entering the furnace. Furthermore, a filtering device is installed on the one-way pressure valve 11 to prevent dust and impurities from entering the furnace body 1, while ensuring the circulation of air and maintaining the pressure balance inside the furnace body 1.

[0028] How it works

[0029] When closing the furnace door 4, the driving motor 3 drives the furnace door 4 to descend through the chain 5. The edge of the furnace door 4 is inserted into the limit block 6 of the door frame 2, squeezing the elastic sealing strip in the limit block 6 to achieve preliminary sealing. At the same time, the electromagnetic device 7 is energized to generate a strong attraction, so that the door frame 2 and the furnace body 1 fit tightly, further enhancing the sealing effect. The pressure sensor 10 in the furnace body 1 monitors the pressure changes in real time. When the pressure exceeds the set threshold, the exhaust valve opens to discharge the high-temperature gas out of the furnace. The exhaust valve 9 is used to keep the pressure in the furnace balanced with the outside world to protect the sealing structure from damage.

[0030] This specific embodiment is merely an explanation of the utility model and is not a limitation of the utility model. After reading this specification, those skilled in the art may make non-creative modifications to this embodiment as needed, but as long as they are within the scope of protection of the utility model, they are protected by patent law.
