Description

Technical Field

[0001] The utility model relates to the technical field of high-temperature gas-pressure sintering furnaces, and specifically relates to a high-temperature gas-pressure sintering furnace with a water-cooled radiator. Background Art

[0002] A high-temperature gas-pressure sintering furnace is a device specifically used for high-temperature sintering. It can perform sintering under relatively high pressure and is suitable for ceramic or metal materials that are difficult to obtain high density by conventional sintering methods or are prone to decomposition when the temperature rises. This sintering technology can significantly improve the mechanical properties of materials, such as hardness, strength, and toughness, and is commonly used for the high-temperature sintering of silicon carbide and silicon nitride.

[0003] As is well known, a high-temperature gas-pressure sintering furnace is usually connected to a baffle valve. When the sintering furnace is inflated, the baffle valve is closed. After sintering is completed, the baffle valve is opened to release the internal high-temperature and high-pressure gas. During this process, the high-temperature and high-pressure gas will cause overheating damage to the baffle valve. The excessive impact force further reduces the service life of the baffle valve, resulting in a decrease in the sealing performance of the baffle valve and even leakage. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a high-temperature gas-pressure sintering furnace with a water-cooled radiator. A water-cooling component is arranged between the high-temperature gas-pressure sintering furnace body and the baffle valve. When sintering is completed and before the baffle valve is opened, the high-temperature and high-pressure gas in the sintering furnace can be water-cooled to accelerate the reduction of the internal temperature of the furnace body. When the baffle valve is opened, the wind plate in the water-cooling component can buffer the released gas, thereby reducing the direct impact on the baffle valve, improving the safety of the baffle valve, and extending the service life of the baffle valve.

[0005] To achieve the above purpose, a high-temperature gas-pressure sintering furnace with a water-cooled radiator is provided, including: a high-temperature gas-pressure sintering furnace body and a baffle valve.

When the main motor is started, the front rotating plate can be rotated, thereby driving the wind plate, the connecting pipe, and the rear rotating plate to rotate together.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0021] Please refer to Figures 1-4, the present utility model provides a technical solution: a high-temperature gas-pressure sintering furnace with a water-cooled radiator, including: a high-temperature gas-pressure sintering furnace body 1 and a baffle valve 3. A water-cooling component 2 is arranged between the high-temperature gas-pressure sintering furnace body 1 and the baffle valve 3. The water-cooling component 2 includes a water-cooling box 201, a main motor 202, a water inlet pipe 203, a cooling component, and a water outlet pipe 211. A main motor 202 and a water inlet pipe 203 are fixedly connected to the front side wall of the water-cooling box 201. The water inlet pipe 203 is located on the left side of the main motor 202. A water outlet pipe 211 is fixedly connected to the rear side wall of the water-cooling box 201. Both the water inlet pipe 203 and the water outlet pipe 211 are connected to an external water supply system (this is prior art and will not be elaborated here) for water-cooling the inside of the high-temperature gas-pressure sintering furnace body 1. A cooling component is arranged inside the water-cooling box 201. The cooling component includes a front water box 204, a front rotating plate 205, a connecting shaft 206, a rear water box 207, a rear rotating plate 208, a wind plate 209, and a connecting pipe 210. A front water box 204 is fixedly connected to the inner front side wall of the water-cooling box 201. A front rotating plate 205 is rotatably connected to the rear side wall of the front water box 204. A connecting shaft 206 is fixedly connected to the front side wall of the front rotating plate 205. A rear water box 207 is fixedly connected to the inner rear side wall of the water-cooling box 201. A rear rotating plate 208 is rotatably connected to the front side wall of the rear water box 207. A wind plate 209 is arranged between the front rotating plate 205 and the rear rotating plate 208. The wind plate 209 is spindle-shaped to increase the windward area. A connecting pipe 210 is rotatably connected to the inside of the wind plate 209. The front and rear ends of the connecting pipe 210 respectively penetrate and connect with the front rotating plate 205 and the rear rotating plate 208. The connecting pipe 210 is made of metal copper. The number of the wind plates 209 and the connecting pipes 210 is multiple and they are evenly distributed between the front rotating plate 205 and the rear rotating plate 208. The front water box 204, the front rotating plate 205, the rear water box 207, the rear rotating plate 208, and the wind plate 209 are all made of heat-conducting ceramic material, which can transfer the high temperature inside the high-temperature gas-pressure sintering furnace body 1 from the high-temperature structure to the low-temperature structure, thereby reducing the temperature.

[0022] Both the main motor 202, the water inlet pipe 203, the cooling component, and the water outlet pipe 211 are provided with two and are distributed left and right on the water-cooling box 201. The output end of the main motor 202 is fixedly connected to the connecting shaft 206. The connecting shaft 206 is rotatably connected to both the front water box 204 and the water-cooling box 201. When the main motor 202 is started, the front rotating plate 205 can be rotated, thereby driving the wind plate 209, the connecting pipe 210, and the rear rotating plate 208 to rotate together. During the rotation process, cooling water enters through the water inlet pipe 203, passes through the front water box 204, the connecting pipe 210, and the rear water box 207, and then is discharged from the water outlet pipe 211, thereby taking out the high temperature inside the high-temperature gas-pressure sintering furnace body 1 to form heat dissipation. At the same time, the wind plate 209 disturbs the gas inside the high-temperature gas-pressure sintering furnace body 1 to accelerate heat dissipation. When the baffle valve 3 is opened, the gas inside the high-temperature gas-pressure sintering furnace body 1 is discharged. When passing through the wind plate 209, it impacts the wind plate 209 to make it rotate, thereby forming a buffer to reduce the impact force and avoid directly impacting the baffle valve 3.

[0023] The water-cooling assembly 2 further includes an air inlet pipe 212 and an air outlet pipe 213. The air inlet pipe 212 is fixedly connected to the left side wall of the water-cooling box 201, and the air outlet pipe 213 is fixedly connected to the right side wall of the water-cooling box 201. The water-cooling box 201 is fixedly connected to the high-temperature gas-pressure sintering furnace body 1 through the air inlet pipe 212, and the water-cooling box 201 is fixedly connected to the baffle valve 3 through the air outlet pipe 213.

[0024] Working principle: After sintering is completed, the main motor 202 is started to rotate the front rotating plate 205, thereby driving the wind plate 209, the connecting pipe 210 and the rear rotating plate 208 to rotate together. During the rotation, the cooling water enters through the water inlet pipe 203, passes through the front water box 204, the connecting pipe 210 and the rear water box 207, and then is discharged from the water outlet pipe 211, thereby taking out the high temperature inside the high-temperature gas-pressure sintering furnace body 1 to form heat dissipation. At the same time, the wind plate 209 disturbs the gas inside the high-temperature gas-pressure sintering furnace body 1 to accelerate heat dissipation. When the baffle valve 3 is opened, the main motor 202 is turned off, and the gas inside the high-temperature gas-pressure sintering furnace body 1 is discharged. When passing through the wind plate 209, it impacts the wind plate 209 to make it rotate, thereby forming a buffer to reduce the impact force and avoid directly impacting the baffle valve 3.

[0025] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments, and various changes can be made without departing from the gist of the present invention within the knowledge scope of those of ordinary skill in the art.
