DETAILED DESCRIPTION

[0022] In order to make the purpose, technical solution and advantages of the embodiments of the utility model clearer, the technical solution in the embodiments of the utility model is described clearly and completely. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] The embodiment of the present application provides an electric vacuum furnace for glass powder molding, which solves the problem that the operation of maintaining the filter of the traditional electric vacuum furnace is inconvenient, and the outer shell of the electric vacuum furnace needs to be opened separately, and then the filter mounting seat arranged on the pipeline inside the shell of the electric vacuum furnace is opened, so as to take out the filter and replace or maintain it. This maintenance method is relatively cumbersome and inconvenient.

[0024] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0025] The utility model embodiment discloses a glass powder forming electric vacuum furnace. Figure 1-4 As shown, it comprises a vacuum furnace body 1, a mounting seat 2 is fixedly connected to the vacuum furnace body 1, and a filter body 3 is movably clamped in the inner cavity of the mounting seat 2;

[0026] A gas circulation pipe 201 is fixedly connected to the mounting base 2;

[0027] A sealing cover 4 is movably connected to the outer shell of the vacuum furnace body 1, and the sealing cover 4 is used to seal the filter body 3;

[0028] The outer shell of the vacuum furnace body 1 is provided with a clamping assembly for quickly limiting the cover 4, and the clamping assembly includes a sleeve seat 5 arranged on the outer shell of the vacuum furnace body 1, and a wedge block 6 is movably clamped inside the sleeve seat 5. A clamping groove 402 is opened on the cover 4, and the wedge block 6 is movably clamped in the clamping groove 402.

[0029] Furthermore, a screw rod 501 is threadedly connected to the sleeve seat 5. After rotation, the screw rod 501 moves spirally along the threaded hole on the sleeve seat 5 and pushes the wedge block 6 to slide along the inner cavity of the sleeve seat 5, thereby conveniently locking or unlocking the position of the cover 4 by shifting the wedge block 6.

[0030] Furthermore, a rotating handle 502 is fixedly connected to the screw rod 501 , and the rotating handle 502 makes it easier and more convenient to rotate the screw rod 501 .

[0031] Furthermore, a lateral support rod 8 is fixedly connected to the vacuum furnace body 1, and a clamping hole 401 is opened on the cover 4. The lateral support rod 8 is movably clamped in the clamping hole 401. The cooperation between the lateral support rod 8 and the clamping hole 401 can provide lateral support to the cover 4, thereby ensuring that the force on the cover 4 is stable.

[0032] Furthermore, a sealing gasket 701 is movably clamped between the vacuum furnace body 1 and the cover 4, and a sealing groove 7 corresponding to the sealing gasket 701 is opened on the vacuum furnace body 1. The design of the sealing gasket 701 ensures good sealing between the cover 4 and the vacuum furnace body 1 after installation and clamping, and the sealing gasket 701 is deformed and seals the interface position after being compressed.

[0033] The glass powder molding electric vacuum furnace facilitates rapid loading of the filter body 3 outside the vacuum furnace body 1, and adopts the design of the sealing cover 4 and the clamping assembly, so that the filter body 3 can be conveniently clamped inside the mounting seat 2 and quickly closed, thereby facilitating installation of the sealing cover 4 and subsequent disassembly, maintenance or replacement, thereby ensuring good impurity filtering effect in the gas circulation, stable gas circulation process, and good glass powder molding effect.

[0034] When installing the filter body 3, firstly, the filter body 3 is clamped in the inner cavity of the mounting seat 2, and then the cover 4 is docked with the lateral support rod 8, and the cover 4 is pushed to fit with the vacuum furnace body 1 and squeeze the sealing gasket 701. At this time, the screw rod 501 is rotated so that the screw rod 501 drives the wedge block 6 to move, and the wedge block 6 is inserted into the slot 402, so as to clamp and limit the cover 4, thereby facilitating the installation of the filter body 3. When disassembling the filter body 3, the above installation process can be reversed.
