[0033] like Figure 1-Figure 2 As shown, the present application provides a vacuum heating furnace, including a shell 1, and a heating furnace body 2 for heating and processing materials, the shell 1 is used to support and fix the heating furnace body 2 and other auxiliary accessories (not shown in the figure) equipped with the heating furnace body 2. Specifically, a fixing frame 11 is fixedly installed inside the shell 1, and the heating furnace body 2 is fixedly installed on the fixing frame 11, and a furnace cover 12 is hinged at one end of the heating furnace body 2, and the heating furnace body 2 can be sealed by the furnace cover 12 to ensure the vacuum effect.

[0034] A connecting pipe 13 is also provided in the shell 1, and one end of the connecting pipe 13 is fixedly installed on the heating furnace body 2. In the present application, the connecting pipe 13 is provided with a plurality of groups of connecting ports (not shown in the figure), and the plurality of connecting ports are used to connect other auxiliary accessories (not shown in the figure) equipped with the heating furnace body 2, for example: an exhaust system, which is used to extract the gas in the heating furnace body 2 to form a vacuum environment inside the heating furnace body 2, as well as a cooling system and a gas control system, etc. The various systems mentioned above are conventional technologies in the field and will not be described in detail here.

[0035] Meanwhile, a support frame 21 is fixedly installed in the heating furnace body 2 , and the support frame 21 supports the materials entering the heating furnace body 2 , keeps the materials stable, and prevents the materials from contacting the heating elements on the inner wall of the heating furnace body 2 .

[0036] In order to conveniently transport the materials into the heating furnace body 2 for heating, a placement rack 3 is also provided in the support frame 21. The width of the placement rack 3 is smaller than the furnace mouth diameter of the heating furnace body 2. The materials can be placed on the placement rack 3 first and then placed on the support frame 21 as a whole.

[0037] To sum up, before heating the material, first open the furnace cover 12 of the heating furnace body 2, then take out the placement rack 3, and place the material to be heated on the placement rack 3 stably, then return the placement rack 3 to the support rack 21 in the heating furnace body 2, and finally close the furnace cover 12 to ensure the sealing of the furnace cover 12.

[0038] Most of the existing fixing frames 11 have fixed sizes and shapes. This design limits the shape of the heated material. Therefore, when processing different types of material heating operations, the fixing frame 11 needs to be replaced as a whole, which increases the complexity of the operation. In order to solve the above problems, specifically:

[0039] like Figure 3-Figure 4 As shown, both side ends of the placement rack 3 are provided with fixing grooves 31, and the fixing grooves 31 run through both sides of the placement rack 3. In the present application, there are multiple groups of fixing grooves 31, and the fixing grooves 31 of each group are opposite and have the same height.

[0040] A shelf plate 34 is slidably connected in the placement rack 3, and placement grooves 35 are provided on both side ends of the shelf plate 34. The number and height of the placement grooves 35 are consistent with the fixed grooves 31, so that installation connecting plates (not shown) can be added in the placement grooves 35 and the fixed grooves 31 to change the space for placing materials on the placement rack 3.

[0041] At the same time, a slide groove 32 is opened on the inner wall of the upper and lower ends of the placement rack 3, and a sliding member 33 is slidably connected in the slide groove 32. In the present application, the end of the sliding member 33 protrudes from the slide groove 32 and is fixed to the upper and lower ends of the shelf plate 34, so that the shelf plate 34 can be pushed to slide in the slide groove 32, which is convenient for adjusting the position of the shelf plate 34.

[0042] In order to prevent the shelf 34 from shaking after adjustment, an empty slot 36 is opened at the top of the placement rack 3. In the present application, the empty slot 36 passes through the top of the placement rack 3 to the empty slot 36, and a screw hole 38 is opened at the end of the sliding member 33 at the upper end. The screw hole 38 is threadedly connected with a bolt 37. It should be noted that the diameter of the mounting head of the bolt 37 is larger than the width of the empty slot 36, and the mounting head of the bolt 37 is located on the surface of the placement rack 3.

[0043] In the present application, all components such as the placement rack 3 and the rack plate 34 are made of high temperature resistant and corrosion resistant materials and have heat conducting functions, such as high temperature alloys, graphite, etc.

[0044] To summarize, after the position of the shelf plate 34 is adjusted, the bolt 37 is screwed into the inside of the empty slot 36 until the mounting head of the bolt 37 is on the surface of the placement rack 3. At this time, the shelf plate 34 is fixed to the placement rack 3 through the clamping force of the bolt 37 and the screw hole 38 on the top of the placement rack 3, thereby fixing the shelf plate 34. If the position of the shelf plate 34 needs to be adjusted, the bolt 37 is loosened first, and the shelf plate 34 is pushed at this time, and the bolt 37 slides in the empty slot 36 with the shelf plate 34. After the adjustment is completed, the bolt 37 can be tightened in the same way as the above steps, so that the placement rack 3 can adapt to different types of materials. The operation is simple and the number of materials placed on the placement rack 3 is increased.

[0045] It should be noted that in the present application, a plurality of connecting plates of different sizes (not shown) are provided in the placement groove 35 and the fixing groove 31. After the shelf plate 34 is adjusted to the desired position, a suitable connecting plate is selected through the placement groove 35 and the fixing groove 31 to change the placement space of the placement rack 3.

[0046] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations.
