Description

Technical Field

[0001] This utility model relates to the field of tubular furnace technology, specifically to a flange cooling device for tubular furnaces. Background Technology

[0002] With the development and progress of science and technology, various new materials and technologies are developing rapidly. High-temperature tube furnaces are commonly used equipment for experiments such as high-temperature annealing, crystal sintering, atmosphere sintering, and oxidation testing of various materials.

[0003] Existing tube furnaces have the following problems in use: 1. During repeated high-temperature experiments with alternating vacuum and atmosphere conditions, the sealing requirements of the tube furnace are extremely stringent. Since the flange seals at both ends of the quartz furnace tubes are made of silicone, the high temperature inside the furnace significantly affects these seals, easily leading to minor leaks. Furthermore, processes requiring extended furnace tubes for cooling may alter the volume, flow rate, and ratio of the atmosphere inside the furnace, introducing uncertainties into the experiment. 2. Different experiments require different durations, especially the artificial crystal cultivation process, which requires simulating environments lasting millions of years using concentrated atmospheres and temperatures. During very long experiments, the impact of high-temperature airflow can significantly affect the flange seals, easily leading to minor leaks. Again, processes requiring extended furnace tubes for cooling may alter the volume, flow rate, and ratio of the atmosphere inside the furnace, introducing uncertainties into the experiment.

[0004] There is an urgent need for a cooling device for tubular furnace flanges to address the technical deficiencies mentioned above. Utility Model Content

[0005] The purpose of this invention is to provide a cooling device for tubular furnace flanges to solve the problem of high-temperature airflow affecting the sealing effect mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a cooling device for a tubular furnace flange, comprising a tubular furnace body, a furnace body tube installed on the side of the tubular furnace body, a sealing flange installed at the end of the furnace body tube, a pipe rack installed on the outside of the furnace body tube, a cooling box provided on the right side of the tubular furnace body, a cooling assembly installed inside the cooling box, a first sealing ring installed at the connection between the sealing flange and the furnace body tube, a cooling water trough opened on the inner side of the sealing flange near the first sealing ring, second sealing rings installed on both sides of the cooling water trough, a water inlet pipe installed at the top of the sealing flange, a water outlet pipe installed at the bottom of the sealing flange, a water supply pipe installed on the left side of the top of the cooling box, a pump body installed on the water supply pipe, a liquid flow meter installed on the water supply pipe to the right of the pump body, a drain pipe installed on the right side of the top of the cooling box, and a sealing connection pipe installed at the connection between the drain pipe and the water supply pipe.

[0007] As a further technical solution of this utility model, the top of the cooling water tank is connected to the inlet pipe, and the bottom of the cooling water tank is connected to the outlet pipe.

[0008] As a further technical solution of this utility model, the cooling water tank is a 6*5MM annular precision-machined tank, and the cooling water tank precisely and efficiently surrounds the quartz furnace tube from top to bottom in 360 degrees.

[0009] As a further technical solution of this utility model, both the first sealing ring and the second sealing ring are O-rings.

[0010] As a further technical solution of this utility model, the sealing connection pipe is connected to the inlet pipe and the outlet pipe by threaded sealing.

[0011] As a further technical solution of this utility model, a water inlet is installed at the top of the cooling box, and the drain pipe passes through the pipe frame and is connected to the interior of the cooling box.

[0012] Compared with the prior art, the beneficial effects of this utility model are: the cooling device for tubular furnace flanges not only realizes the function of convenient continuous cooling and temperature reduction, and the function of stable control of water cooling flow, but also realizes the function of convenient circulating cooling.

[0013] (1) By setting up a cooling box, a first sealing ring, a sealing flange, a liquid flow meter, an inlet pipe, a cooling water tank, a second sealing ring, and an outlet pipe, in order to avoid the high temperature affecting the sealing components such as the first sealing ring on the sealing flange, the pump body can continuously deliver cold water to the inside of the sealing flange during the operation of the tubular furnace body. The cold water enters the cooling water tank from the inlet pipe and is discharged from the outlet pipe. The cold water can flow from top to bottom through the sealing flange. The liquid flow meter can control the flow rate of the cold water to ensure the stable pressure of the cooling water. The second sealing ring plus stable water pressure can effectively ensure the smooth flow of cooling water and the cooling effect. Continuous cooling can avoid the problem of the sealing components on the sealing flange being affected by heat. This structure achieves the function of cooling and sealing protection without affecting the internal volume, flow rate, and ratio of the tubular furnace.

[0014] (2) By setting up a water supply pipe, a pump body, a liquid flow meter and a sealing connection pipe, the tubular furnace body first seals the sealing connection pipe to the water inlet pipe and the water outlet pipe respectively during the operation. The sealing flange and the cooling box form a sealed flow channel through the pipe. When the pump body delivers cold water to the inside of the sealing flange, the liquid flow meter can control the flow rate of the cold water to ensure the stable pressure of the cooling water. The second sealing ring plus stable water pressure can effectively ensure the smooth flow of cooling water and the cooling effect. This structure realizes the function of easy and stable control of cooling.

[0015] (3) By setting up a cooling box, cooling components, water supply pipe, pump body and drain pipe, the pump body delivers cold water inside the cooling box to the inside of the sealing flange. After passing through the cooling water tank, the cold water is discharged from the outlet pipe into the drain pipe. The water in the drain pipe flows back into the cooling box. The cooling components inside the cooling box can cool the returned water again to achieve the function of circulating cooling. This structure realizes the function of easy circulating cooling.

Continuous cooling can prevent the sealing components on the sealing flange 8 from being affected by heat and causing sealing problems.
