Description

Technical Field

[0001] The utility model provides a top exhaust pipeline device of a vacuum system of high-temperature purification equipment, belonging to the technical field of carbon-based material production equipment. Background Art

[0002] The top exhaust pipe of the vacuum system is mainly used to extract the gas inside the insulation system of the high-temperature purification equipment into the vacuum pipe with a water-cooling jacket. When installing the insulation system inside the high-temperature purification equipment, some errors are inevitable. In order to smoothly install the top exhaust pipe of the vacuum system, the top exhaust pipe of the vacuum system is usually set into a telescopic sleeve form (divided into two parts, upper and lower). The lower part of the top exhaust pipe of the vacuum system is placed on the top of the insulation system, and the boss of the upper part of the vacuum system exhaust pipe is hung on the furnace body of the high-temperature purification equipment. The upper and lower parts are connected by sleeves to reduce the pressure thrust and compensate for the pipeline installation error. Figure 1 and Figure 2 However, the arrangement of the boss on the upper exhaust pipe increases the force-bearing area, causing the upper exhaust pipe to move up and down during vacuum extraction, which may be severely damaged. Utility Model Content

The purpose is to avoid damage to the exhaust pipeline during the exhaust process by improving the hardware structure of the exhaust pipeline and adjust the installation error at the same time.

[0004] In order to solve the above technical problems, the technical solution adopted by the utility model is as follows: a high-temperature purification equipment vacuum system top exhaust pipeline device, including an exhaust pipeline, one end of the exhaust pipeline is provided with a heat preservation system, and the other end of the exhaust pipeline is provided with a water-cooling jacket vacuum pipeline;

[0005] The air extraction pipeline includes a first air extraction pipe and a second air extraction pipe, and the first air extraction pipe and the second air extraction pipe are coaxially arranged;

[0006] The first air extraction pipe and the second air extraction pipe are fixedly connected via an adjusting device;

[0008] The first adjustment hole is provided at one end of the first air extraction pipe, and the second adjustment hole is provided at one end of the second air extraction pipe, and the first adjustment hole and the second adjustment hole cooperate with each other;

[0009] The fixing device is in clearance fit with the first adjustment hole, and the fixing device is in clearance fit with the second adjustment hole.

[0010] Furthermore, the fixing device is a carbon-carbon bolt.

[0011] Furthermore, the first air extraction pipe and the second air extraction pipe are both straight pipe structures.

Compared with the traditional telescopic exhaust pipe of the utility model, when the gas inside the insulation system of the high-temperature purification equipment is extracted into the vacuum pipe with the water cooling jacket, the first exhaust pipe and the second exhaust pipe will not be displaced relative to each other, which can effectively avoid damage to the exhaust pipe;

When installing the exhaust pipe of the utility model, the appropriate hole position is selected according to the position of the insulation system and fixed with carbon-carbon screws, which can effectively eliminate the installation error caused by the installation of the insulation system and compensate for the installation error of the pipe;

[0018] 3. Compared with the traditional exhaust pipeline, the exhaust pipeline of the present invention eliminates the boss setting used to hang the exhaust pipeline on the furnace body of the high-temperature purification equipment, making the structure simpler and easier to manufacture.

DETAILED DESCRIPTION

[0027] like Figures 1 to 5 As shown, the present invention provides an exhaust pipeline device for the top of a vacuum system of high-temperature purification equipment, including an exhaust pipeline 2. The exhaust pipeline 2 is placed in a furnace body 4. One end of the exhaust pipeline 2 is fixed to the air outlet at the top of the insulation system 1, and the other end of the exhaust pipeline 2 is fixed to the air inlet of the water-cooling jacket vacuum pipeline 3. Specifically, the exhaust pipeline 2 includes a first exhaust pipe 8 and a second exhaust pipe 9. The first exhaust pipe 8 and the second exhaust pipe 9 are coaxially arranged. The upper end of the first exhaust pipe 8 is placed at the air inlet of the water-cooling jacket vacuum pipeline 3, and the first exhaust pipe 8 and the pipe at the air inlet of the water-cooling jacket vacuum pipeline 3 are coaxially arranged. The lower end of the second exhaust pipe 9 is placed at the air outlet at the top of the insulation system 1, and the second exhaust pipe 9 and the pipe at the air outlet at the top of the insulation system 1 are coaxially arranged.

[0028] The lower end of the first exhaust pipe 8 and the upper end of the second exhaust pipe 9 are fixedly connected via an adjustment device, which includes a plurality of fixing devices 7, a plurality of first adjustment holes 5, and a plurality of second adjustment holes 6. Specifically, a plurality of first adjustment holes 5 are provided through the side wall of the lower end of the first exhaust pipe 8. The plurality of first adjustment holes 5 are provided in different positions and can be arranged in an array; a plurality of second adjustment holes 6 are provided through the side wall of the upper end of the second exhaust pipe 9. The plurality of second adjustment holes 6 are provided in different positions and can be arranged in an array. The first adjustment holes 5 and the second adjustment holes 6 cooperate with each other, and the fixing device 7 fixes the first exhaust pipe 8 and the second exhaust pipe 9 together through the first adjustment holes 5 and the second adjustment holes 6. When assembling the exhaust pipe 2 of the present invention, the first exhaust pipe 8 and the second exhaust pipe 9 are fixedly connected by selecting appropriate first adjustment holes 5 and second adjustment holes 6 according to the position of the insulation system 1, which can effectively compensate for pipeline installation errors.

The upper exhaust pipe 2 and the lower exhaust pipe 2 are connected into a whole with a carbon-carbon screw to increase their own gravity. When exhausting, they will not be pumped, the exhaust pipe 2 will not be damaged, and the purpose of adjusting the error is achieved.

[0030] In this embodiment, the diameter of the first air extraction pipe 8 is larger than the diameter of the second air extraction pipe 9 , that is, the inner wall of the first air extraction pipe 8 fits the outer wall of the second air extraction pipe 9 .
