Description

Technical Field

[0001] The utility model relates to the technical field of muffle furnaces, in particular to a muffle furnace. Background Art

[0002] A muffle furnace is a commonly used high-temperature heating device, which is widely used in industrial production and laboratories. It is often used for heat treatment of products, detection of samples and scientific experiments. In daily life, whether in production or life, a large amount of sludge will be generated, and the sludge needs to be purified by using relevant equipment. There are many types of elements in the sludge, and different elements need to be classified and treated. The muffle furnace can extract precious metal elements from the sludge to improve the recycling rate of the sludge.

[0003] At present, the muffle furnace is composed of a single furnace body with a smoke exhaust port at the top. During the processing of many organic matter samples, a large amount of smoke will be generated. Generating a large amount of smoke indoors will cause the indoor smoke alarm to go off, and generating a large amount of smoke outdoors will cause environmental pollution. However, the muffle furnaces on the market lack relevant structures for treating smoke, which makes the smoke have an impact during actual experiments or production processes, resulting in a slowdown in the experimental or production progress or deviation in results.

An absorption mechanism is provided on the outer side wall of the base 2. The absorption mechanism includes a guide rail 3, a rotating rod 4, a mounting seat 8, and a motor 11. The motor 11 is fixed to the inner side wall of the base 2 by bolts. The rotating rod 4 is rotatably connected to the outer side wall of the base 2 through a rotating shaft. The output end of the motor 11 is connected to the rotating shaft. An inner plate 6 is slidably connected to the inner wall of the rotating rod 4. A fitting head 5 is welded to the outer side wall of the inner plate 6. The guide rail 3 is fixed to the outer side wall of the furnace body 1 by bolts. The fitting head 5 is matched with the guide rail 3. The mounting seat 8 is fixed to the outer side wall of the furnace body 1 by bolts. A folding plastic pipe 7 is bonded to the inner wall of the mounting seat 8. The outer side wall of the folding plastic pipe 7 is connected to the inner plate 6. An inhalation component is provided inside the base 2. The inhalation component is connected to the mounting seat 8;

[0027] During use, when electrolytically extracting precious metals from sludge through the furnace body 1, the motor 11 can be turned on to make the rotating rod 4 rotate. When the rotating rod 4 rotates, the fitting head 5 outside the inner plate 6 cooperates with the guide rail 3 to drive the folding plastic pipe 7 to gradually cover the top of the furnace body 1. When the furnace body 1 discharges smoke, the suction assembly is turned on, so that the smoke is absorbed and processed through the folding plastic pipe 7 and the mounting seat 8, reducing the impact of the smoke.

[0028] The suction assembly includes an air pump 10 and an outer box 12. The air pump 10 is located on the inner side wall of the base 2. The input end and the output end of the air pump 10 are respectively connected with a first connecting pipe 9 and a second connecting pipe 13 through flanges. The outer box 12 is slidably connected to the inner side wall of the base 2. The other end of the second connecting pipe 13 is connected to the outer box 12 through a flange. An inner box 14 is movably inserted into the inner side wall of the outer box 12;

[0029] During use, adsorption filler can be added into the inner box 14. The air pump 10 is turned on to suck the smoke into the first connecting pipe 9, discharge it into the outer box 12 through the second connecting pipe 13, and absorb it through the adsorption filler in the inner box 14, reducing the diffusion of the smoke and facilitating treatment.

[0030] Working principle: When electrolytically extracting precious metals from sludge through the furnace body 1, the motor 11 can be turned on to make the rotating rod 4 rotate. When the rotating rod 4 rotates, the fitting head 5 outside the inner plate 6 cooperates with the guide rail 3 to drive the folding plastic pipe 7 to gradually cover the top of the furnace body 1. The air pump 10 is turned on to suck the smoke into the first connecting pipe 9, discharge it into the outer box 12 through the second connecting pipe 13, and absorb it through the adsorption filler in the inner box 14, reducing the diffusion of the smoke. Embodiment 2

[0031] For a muffle furnace, in order to facilitate the fixation of the inner box 14, as Figures 2 - 5 shown, a connecting column 15 is welded to the outer side wall of the inner box 14. The connecting column 15 is movably inserted into the inner wall of the outer box 12. An installation box 20 is welded to the outer side wall of the base 2. A partition plate 21 is welded to the inner side wall of the installation box 20. A pull plate 16 is slidably connected to the inner wall of the partition plate 21. A clamping plate 17 is slidably connected to the bottom inner wall of the installation box 20. The clamping plate 17 cooperates with the connecting column 15. A spring 19 is welded between the clamping plate 17 and the inner wall of the installation box 20. A connecting rod 18 is rotatably connected to the outer side wall of the clamping plate 17. The connecting rod 18 is rotatably connected to the top outer wall of the pull plate 16;

[0032] Working principle: After adding adsorption packing into the inner box 14, insert the inner box 14 into the outer box 12. The connecting column 15 gradually passes through the inner wall of the outer box 12, squeezing the clamping plate 17 to compress the spring 19. After the insertion process of the inner box 14 is completed, the clamping plate 17 is clamped inside the connecting column 15 to fix the connecting column 15, thereby realizing the quick fixation of the inner box 14. When it is necessary to remove the inner box 14, the pull plate 16 can be pulled to make the connecting rod 18 push the clamping plate 17 to move to both sides, canceling the clamping of the connecting column 15. At this time, the inner box 14 and the connecting column 15 can be directly pulled out.

[0033] The above are only the preferred specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered within the protection scope of the present invention.
