Description

Technical Field

[0001] The utility model relates to the field of vacuum pumps, in particular to a vacuum furnace with a vacuum pump unit. Background Art

[0002] The vacuum pump unit is a key equipment used to create and maintain the necessary vacuum level in a vacuum furnace. The vacuum pump unit must be able to quickly pump out a large amount of gas in a short period of time to quickly reduce the pressure of the vacuum furnace. Different vacuum furnaces and applications may require vacuum pump units of different types and specifications to meet specific vacuum requirements and operating conditions. A vacuum furnace with a vacuum pump unit is a key equipment for achieving a high vacuum environment and plays an important role in a variety of industrial and scientific research applications.

[0003] However, most of the vacuum furnaces with vacuum pump units now have the following problems:

[0004] First, the existing vacuum furnace with a vacuum pump unit, when using the vacuum pump, is mostly connected by a flange on the pipeline with multiple bolts, but the installation and removal of multiple bolts during connection is troublesome and time-consuming. When the vacuum pump needs to be inspected and maintained, the disassembly is time-consuming and laborious, and it is inconvenient to connect and use conveniently.

[0005] 2. In the existing vacuum furnaces with vacuum pump units, when using the vacuum pump, the vacuum pump is mostly bolted or directly placed next to the vacuum furnace for use. Most vacuum pumps do not have a limit function. If a worker collides with the vacuum pump when passing by, it is easy to cause the vacuum pump to deviate and collide, causing damage, making it inconvenient to provide convenient limit protection for the vacuum pump in use.

[0006] Therefore, we make improvements to this and propose a vacuum furnace with a vacuum pump unit. Utility Model Content

[0037] Embodiment 2:

[0038] The solution in Example 1 is further introduced below in combination with a specific working method, as described below:

[0039] like Figure 4 As shown, as a preferred embodiment, on the basis of the above method, further, through holes are opened at equal angles on the card plate 3, and the length and width of the through holes are greater than the length and width of the baffle 10, which can ensure that the baffle 10 can pass through the through holes on the card plate 3.

[0040] like Figure 3As shown, as a preferred embodiment, on the basis of the above method, further, the side end face of the clamping plate 3 is in contact with the inner side face of the mounting frame 7, and the side end face of the moving block 9 is in contact with the inner side face of the mounting frame 7, which can ensure that when the threaded rod 8 pushes the moving block 9 to move, the moving block 9 can move smoothly through the support of the inner side face of the mounting frame 7.

[0041] like Figure 5 As shown, as a preferred embodiment, on the basis of the above method, further, the threaded rods 8 are distributed at equal angles in the mounting frame 7, and the threaded rods 8 correspond one-to-one with the baffles 10 through the moving blocks 9, which can ensure that multiple baffles 10 can push and squeeze the card plate 3.

[0042] like Figure 6 As shown, as a preferred embodiment, on the basis of the above method, further, the first springs 14 are distributed at equal angles in the rotating frame 13, and the first springs 14 correspond one-to-one with the clamping rods 16 through the fixing plates 15, which can ensure that the clamping of the clamping rods 16 can limit the rotating frame 13.

[0043] like Figure 8 As shown, as a preferred embodiment, on the basis of the above-mentioned method, further, the upper limit sliding connection of the mounting plate 22 is provided with a guide rod 26, and the guide rod 26 is fixedly connected with a clamping plate 27, and the cross-section of the pressing block 25 is an isosceles triangle, which can ensure that the pressing block 25 in the form of an isosceles triangle is inclined on one side, and when the clamping plate 27 moves, the through hole of the clamping plate 27 can push the pressing block 25 to move downward, thereby pressing and limiting the device.

[0044] Specifically, when the vacuum furnace with the vacuum pump unit is used: Figure 1-8When the delivery pipe 6 with the vacuum pump body 19 is spliced ​​and used, the card plate 3 on the connecting pipe 2 can be inserted into the mounting frame 7, and the baffle 10 can pass through the through hole on the card plate 3, and then the protrusion 18 on the mounting frame 7 can be engaged in the groove 4 of the connecting pipe 2, and then the card plate 3 is rotated to move the through hole away from the baffle 10, and then the pull plate 17 can be pulled to drive the fixed plate 15 to move through the card rod 16, and the fixed plate 15 is separated from the mounting frame 7 during movement, and the fixed plate 15 squeezes the first spring 14, and when the rotating frame 13 is not hindered, the rotating frame 13 can be rotated, and the rotating frame 13 drives the gear block 12 When the wheel 11 rotates, the gear 11 drives the threaded rod 8 to rotate. When the threaded rod 8 is running, it can drive the moving block 9 and the baffle 10 to move. The baffle 10 pushes the card plate 3 to firmly clamp the card plate 3 and squeeze it on the mounting frame 7, and cooperate with the sealing gasket 5 in the groove 4 to improve the sealing protection effect. After the splicing is completed, the pull plate 17 is released, and the fixed plate 15 and the card rod 16 are reset under the push of the first spring 14, and the rotating frame 13 is clamped and limited. The rotating frame 13 is rotated only by pulling the pull plate 17, which improves the splicing and disassembly efficiency, and can smoothly splice the delivery pipe 6 on the vacuum pump body 19 to the connecting pipe 2 of the vacuum furnace body 1.

[0045] When the vacuum pump body 19 is placed in a limited position, the hydraulic cylinder 21 in the support plate 20 can be opened. When the hydraulic cylinder 21 pushes the mounting plate 22 to move, the clamping plates 27 on the mounting plates 22 on both sides clamp the vacuum pump body 19. When the mounting plate 22 continues to move, the clamping plates 27 are supported by the guide rods 26 to move smoothly. The inclined through holes of the clamping plates 27 can push the inclined surface of the pressing block 25, driving the pressing block 25 to move downward. When the pressing block 25 moves downward, it is supported by the guide block 24 to move smoothly, and the guide block 24 can squeeze the second spring 23, and the pressing block 25 moves downward. The shift can limit the downward pressure on the vacuum pump body 19 to prevent the vacuum pump body 19 from being bumped and offset, which affects the use effect. The vacuum pump body 19 can be used to evacuate the vacuum furnace body 1 to improve the use effect. When the clamped vacuum pump body 19 needs to be loosened later, the hydraulic cylinder 21 can be used to drive the mounting plate 22 to reset. The pressure block 25 is not hindered by the clamping plate 27. Under the push of the second spring 23, the guide block 24 and the pressure block 25 are driven to reset, which is convenient for loosening the clamped vacuum pump body 19. The vacuum pump model used is "STP-60 vacuum pump".

[0046] The above embodiments are only used to illustrate the utility model but not to limit the technical solutions described in the utility model. Although the present invention has been described in detail with reference to the above embodiments, the utility model is not limited to the above specific implementation methods. Therefore, any modification or equivalent replacement of the utility model; and all technical solutions and improvements that do not deviate from the spirit and scope of the utility model are included in the scope of the claims of the utility model.
