[0002] Vertical vacuum cleaning furnace is a specially designed heat treatment equipment, which adopts a vertical structure and cleans the workpiece in a vacuum environment. The equipment can effectively remove impurities such as grease, oxides, pollutants, etc. on the surface of the workpiece through heating and vacuum treatment, while preventing the workpiece from being oxidized or otherwise contaminated during the heating process. Vertical vacuum cleaning furnaces are widely used in electronics, metallurgy, chemical industry, aerospace and other fields to clean workpieces that require high cleanliness surfaces.

[0003] When the waste in the waste collection tank in the vertical vacuum cleaning furnace accumulates to a certain extent, the operator can stop the equipment, wait for the equipment to cool down, open the sealing device of the waste collection tank, and remove the waste collection tank from the equipment to discharge the waste.

[0004] At present, the disassembly steps of the waste collection tank in the traditional vertical vacuum cleaning furnace are relatively complicated, and the waste may leak during the disassembly process, causing environmental pollution and safety hazards, which is not conducive to the user to disassemble and discharge the waste collection tank. Summary of the invention

[0005] The purpose of the present invention is to solve the shortcomings of the prior art and to propose a vertical vacuum cleaning furnace.

[0006] In order to achieve the above object, the present invention adopts the following technical solutions: A vertical vacuum cleaning furnace comprises a vertical vacuum cleaning furnace body and a base, wherein a sewage outlet is arranged at the bottom of the vertical vacuum cleaning furnace body, an upper flange is fixedly arranged on the sewage outlet, the base is located at the bottom of the upper flange, and a detachable waste tank is installed in the base; a feed port is fixedly arranged at the top of the waste tank, a lower flange is fixedly arranged at the top of the feed port, a fixing plate is fixedly arranged on one side of the upper flange, and a cover plate is installed at the bottom of the fixing plate.

[0007] In addition, a preferred structure is that support plates are fixedly and vertically arranged on both sides of the fixed plate, and both ends of the support plates are fixedly connected to the support legs of the vertical vacuum cleaning furnace body.

[0008] In addition, a preferred structure is that movable cavities are opened on both sides of the support plate, movable blocks are arranged in the movable cavities for transverse movement, guide columns are fixedly arranged in the movable cavities, and the movable blocks are guided to move by the guide columns.

[0010] In addition, a preferred structure is that a plurality of magnetic columns are fixedly and vertically arranged downwardly at the bottom of the cover plate, and corresponding card pieces on the cover plate are adapted to be provided with card cavities.

[0011] In addition, a preferred structure is that an assembly groove is opened on the feed port below the lower flange, an electromagnet ring is fixedly installed in the assembly groove, and magnetic holes are adapted to be opened on the top of the electromagnet ring corresponding to the magnetic column, and the magnetic holes and the magnetic column are adapted to attract each other.

DETAILED DESCRIPTION

[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0019] Reference Figure 1-7 A vertical vacuum cleaning furnace comprises a vertical vacuum cleaning furnace body 1 and a base 2. A sewage outlet is arranged at the bottom of the vertical vacuum cleaning furnace body 1, an upper flange 11 is fixedly arranged on the sewage outlet, the base 2 is located at the bottom of the upper flange 11, and a detachable waste tank 3 is installed in the base 2. A feed port 31 is fixedly arranged at the top of the waste tank 3, a lower flange 32 is fixedly arranged at the top of the feed port 31, a fixing plate 4 is fixedly arranged on one side of the upper flange 11, and a cover plate 5 is installed at the bottom of the fixing plate 4.

[0020] Among them, the principle of the vertical vacuum cleaning furnace body 1 is mainly based on the cracking characteristics of high molecular polymers in a vacuum state isolated from air and under high temperature conditions. The equipment first heats the object to be cleaned to a certain temperature, so that the high molecular polymer on the surface of the workpiece melts and flows into the waste collection tank, and then heats it to 400-500°C, and at the same time turns on the vacuum pump and introduces a small amount of air to fully oxidize the remaining high molecular polymers to generate harmless substances such as carbon dioxide and water, which are then pumped out of the waste tank 3 outside the furnace through the vacuum pump and water spray scrubber, thereby achieving the purpose of cleaning. It is worth noting that the specific cleaning structure and working mode of the vertical vacuum cleaning furnace body 1 are both prior art, and do not belong to the main technical problems to be solved in the present invention, so they will not be elaborated.

[0021] Among them, support plates 41 are fixedly and vertically arranged on both sides of the fixing plate 5, and both ends of the support plate 41 are fixedly connected to the support legs of the vertical vacuum cleaning furnace body 1. Through the arrangement of the support plates 41, the fixing plate 4 can be fixedly installed on the vertical vacuum cleaning furnace body 1, so that the cover plate 5 can be stably installed on the fixing plate 4.

[0022] Therein, both sides of the support plate 4 are provided with movable cavities 42, movable blocks 43 are disposed in the movable cavities 42 for transverse movement, guide posts 421 are fixedly disposed in the movable cavities 42, and the movable blocks 43 are guided to move by the guide posts 421. The provision of the guide posts 421 can improve the stability of the movable blocks 43 when they are located in the movable cavities 42 and move.

[0023] The bottom of the movable block 43 is fixed with a second magnetic block 431, and the second magnetic block 431 is fixed with a clamp 432 vertically disposed toward the cover plate 5, and a spring 44 is installed between the movable blocks 43 on both sides. By setting the elastic force of the spring 44, the movable blocks 43 on both sides can be tightened toward the middle.

[0024] Among them, the bottom of the cover plate 5 is fixed downwardly and vertically provided with a plurality of magnetic pillars 51, and the corresponding clamping members 432 on the cover plate 5 are adapted to open a clamping cavity 52. ​​Through the adaptation and clamping between the clamping member 432 and the clamping cavity 52, the cover plate 5 can be clamped on the bottom of the fixed plate 4.

[0025] Among them, an assembly groove 311 is provided on the feed port 31 below the lower flange 32, and an electromagnet ring 35 is fixedly installed in the assembly groove 311, and a magnetic hole 351 is adapted to be provided on the top of the electromagnet ring 35 corresponding to the magnetic column 51, and the magnetic hole 351 and the magnetic column 51 are adapted to attract each other. A battery is provided inside the electromagnet ring 35. When the electromagnet ring 35 is turned on, a magnetic force is generated in the magnetic hole 351 on the electromagnet ring 35, and the magnetic column 51 can be fixedly adsorbed in the magnetic hole 351 by magnetic attraction. It is worth noting that the specific structure and working mode of the electromagnet ring 35 are both existing technologies, so no further elaboration is required.

[0026] A plurality of through holes 321 are vertically formed on the lower flange 32 , the through holes 321 are aligned with the magnetic holes 351 , and the magnetic columns 51 are inserted into the magnetic holes 351 through the through holes 321 .

[0027] Among them, fixed seats 33 are fixedly arranged on both sides of the feed port 31, and first magnetic blocks 34 are fixedly arranged on the tops of the fixed seats 33, and the first magnetic blocks 34 and the second magnetic blocks 431 are adapted to attract each other. Through the mutual adsorption between the first magnetic block 34 and the second magnetic block 431, when the first magnetic block 34 moves to the outside of the second magnetic block 431, the movable blocks 43 move outward, the springs 44 are stretched, and the clamps 432 are detached from the clamping cavity 52.

[0028] In this embodiment, when the user needs to disassemble the waste tank 3, he only needs to stop the vertical vacuum cleaning furnace body 1 first, then remove the bolts on the upper flange 11, and then pull the waste tank 3 outwards through the handle.

[0029] When the lower flange 32 on the waste tank 3 moves to the bottom of the cover plate 5, the first magnetic blocks 34 on both sides of the feed port 31 can adsorb the second magnetic block 431 through magnetic force. This allows the movable blocks 43 on both sides to move outward synchronously through the movement of the second magnetic block 431. At this time, the spring 44 is stretched, and the clamps 432 are detached from the clamping cavity 52. ​​At this time, the cover plate 5 is no longer clamped by the clamps 432, so that the cover plate 5 can move downward to the top of the lower flange 32 by its own gravity, and the magnetic column 51 at the bottom of the cover plate 5 also drops synchronously. The magnetic columns 51 all pass through the through hole 321 and enter the magnetic hole 351, so that the cover plate 5 can be fixedly installed on the lower flange 32 by the magnetic force of attraction between the magnetic hole 351 and the magnetic column 51, so that the waste tank 3 can be sealed again. In this way, the waste tank 3 can be pulled out again, so that the waste tank 3 can be disassembled to discharge the waste.

[0030] Furthermore, an anti-slip cover is provided at the bottom of the fixed plate 4, so that when the user moves the favorite flange 32 to the bottom of the cover plate 5, the first magnetic block 34 is located at the bottom of the fixed plate 4, so that the friction between the first magnetic block 34 and the fixed plate 4 can be increased by the anti-slip cover to increase the resistance when the user pulls outward, so as to facilitate the user to position. And when the through hole 321 on the lower flange 32 is aligned with the magnetic column 51 on the cover plate 5, the first magnetic block 34 is completely located on the outside of the second magnetic block 431. At this time, the magnetic attraction force exerted by the first magnetic block 34 on the second magnetic block 431 is the strongest. Therefore, only at this time can the second magnetic block 431 be completely adsorbed by the first magnetic block 34, so that the spring 44 is fully stretched, so that the card 432 is completely detached from the card cavity 52.

[0031] Furthermore, threads are provided in the through holes in the upper flange 11 and the lower flange 23 , so that when the upper flange 11 and the lower flange 23 are connected, the upper flange 11 and the lower flange 23 can be fixed by bolts.

[0032] In the present invention, when the user removes the waste tank 3, he only needs to pull the waste tank 3 outward, so that the clamping device 432 and the clamping cavity 52 can be released by the magnetic attraction between the first magnetic block 34 and the second magnetic block 431, so that the cover plate 5 can automatically fall on the lower flange 32 when the waste tank 3 is removed, and the cover plate 5 can be fixed by the adsorption between the magnetic column 51 and the magnetic hole 351. This method of removing the waste tank 3 is not only convenient, but also the feed port 31 can be automatically blocked by the cover plate 5 during removal to prevent waste leakage.

[0033] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
