Description

Technical Field

[0001] The present application relates to the technical field of furnace cleaning, and in particular to a furnace cleaning device for a sintering furnace. Background Art

[0002] A vacuum sintering furnace is a furnace that performs protective sintering on heated objects in a vacuum environment. It is a complete set of equipment that uses the principle of medium-frequency induction heating to sinter carbide tool heads and various metal powder compacts under vacuum conditions. It is designed for the industrial production of carbide, metal, and ceramic materials. After a period of use, a certain amount of metal powder, oxides, or other chemicals will remain on the inner wall of the sintering furnace. Then, the staff needs to regularly clean the impurities on the inner wall of the furnace. On the one hand, it is convenient to collect the internal impurities through the inner wall of the furnace, and on the other hand, it is convenient to detect the impurity components after cleaning, so as to make full use of these data to guide production and continuously improve the level of sintering technology.

[0003] Traditional cleaning methods usually use brushes, air blowing and other methods to clean impurities on the inner wall of the furnace. For example, a Chinese patent document with a publication number of CN220061793U discloses a furnace inner wall cleaning device, including a box, a first cleaning mechanism, a second cleaning mechanism and an even number of motion mechanism components, each group of motion mechanism components includes four motion mechanisms, the box includes a mounting plate arranged along its side wall, and the first cleaning mechanism also includes a fixed seat, a lifting mechanism, a fixed plate and a brush roller. When the motor of the first cleaning mechanism is working, the first cleaning mechanism can adjust the position of the brush roller by the forward and reverse rotation of the motor, which is convenient for adjustment according to different square carbonization furnaces, so that the brush roller is fully in contact with the inner wall of the square carbonization furnace to achieve efficient cleaning operation.

[0004] In the above-mentioned related technologies, when cleaning impurities on the inner wall of the furnace, it is directly cleaned by a brush. Although the impurities on the inner wall of the furnace can be cleaned, a large amount of dust is likely to appear during the cleaning process. The dust will be adsorbed on the inner wall of the furnace later, thereby affecting the cleaning effect of the inner wall of the furnace; in addition, the impurities in different areas of the inner wall of the furnace are mixed together by cleaning with a brush, and it is not easy for the staff to determine which area of ​​the furnace has a problem when analyzing the impurities later. Summary of the invention

[0005] The present application provides a sintering furnace hearth cleaning device, which aims to solve the problem of impurities in different areas of the inner wall of the hearth being mixed together in the related art.

[0008] By adopting the above technical scheme, when cleaning the inner wall of the furnace, first remove the track in the sintering furnace, and then move the cleaning ring towards the direction close to the sintering furnace. In the initial state, the second abutment ring does not abut on the inner wall of the furnace.

Then, the inner wall of the furnace can be cleaned in sections by the adsorption component. At the same time, the occurrence of dust can be reduced during cleaning. In addition, due to the segmented treatment, it is convenient to collect impurities in different areas of the inner wall of the furnace separately, and then it is convenient for subsequent detection and analysis, so as to better detect the condition of the sintering furnace when in use. In addition, after the impurities in the suction channel are cleaned, it is first necessary to adjust the component to no longer close the suction channel, and then the cleaning ring is not easy to scrape the impurities on the inner wall when moving.

The arc-shaped pushing block pushes the connecting sheet to slide on the connecting ring, thereby facilitating the movement of the elastic abutment sheet. When the elastic abutment sheet moves, the arc-shaped rubber sheet will be deformed, and then the elastic abutment sheet will be driven to deform as well, and finally the purpose of abutting against the inner wall of the furnace is achieved.

When the suction pump 22 sucks impurities into the pressing channel 74, the mobile plate 72 is driven to move by the extrusion cylinder 73, and the impurities in the pressing channel 74 are compacted under the action of the extrusion plate 71. At the same time, a feed port 64 is provided on the fixed plate 6, and a buffer assembly 8 is provided in the collection box 61. The buffer assembly 8 blocks the feed port 64 on the one hand, and slows down the speed at which the agglomerated impurities enter the collection box 61 on the other hand, thereby reducing the occurrence of crushing of the compacted impurities.

One end of the buffer spring 82 is fixed on the collection box 61. The buffer plate 81 is pushed to move into the discharge port 64 by the buffer spring 82, and the discharge port 64 is blocked. When the impurities are compacted, the agglomerated impurities will push the buffer plate 81 to move under the action of gravity, and then the buffer plate 81 is moved into the collection box 61. In this embodiment, the buffer plate 81 is set as a hollow plastic structure, so that the buffer spring 82 can push the buffer plate 81 to move into the discharge port 64. When the agglomerated impurities fall into the collection box 61, the mounting plate 62 is driven to move by the moving cylinder 63, and then the adjacent collection box 61 and the discharge port 64 are made to correspond. At this time, the buffer plate 81 is pushed into the discharge port 64 under the action of the buffer spring 82, so as to facilitate the collection of impurities in another area.

Then, when the agglomerated impurities push the buffer plate 81 to move into the collecting box 61, the bottom of the collecting bag 10 also enters the collecting box 61. Finally, the agglomerated impurities in the collecting box 61 can be easily removed during detection.

[0045] Reference Figure 1-Figure 6A pressing plate 65 is slidably connected to the collecting box 61, and the pressing plate 65 is used to press the agglomerated impurities that fall into the collecting box 61, thereby making the agglomerated impurities more stable in the collecting box 61; a moving component 9 is provided on the mounting plate 62 for driving the pressing plate 65 to move, and the moving component 9 includes a moving screw 91 rotatably connected to the bottom of the collecting box 12 and a moving rod 92 passed through the moving screw 91, and the moving rod 92 is fixed on the pressing plate 65, and the moving screw 91 can be rotated to drive the moving rod 92 to slide, and then the pressing plate 65 is driven to move by the moving rod 92, so that the collected agglomerated impurities can be pressed. In addition, when the pressing plate 65 does not move, the opening of the collecting box 61 is larger, which is convenient for the agglomerated impurities to fall into the collecting box 61.

[0046] Reference Figure 1-Figure 6 In other embodiments, in order to facilitate the cleaning of impurities on the inner wall of the furnace, a scraper is arranged in the suction channel 05, and the scraper rotates along the circumference of the connecting ring 111. At the same time, a driving component is arranged on the first abutting ring 112, and the scraper is driven to rotate by the driving component, and then the scraper can scrape off the impurities attached to the inner wall of the furnace. The driving component can be configured to be a driving magnet rotatably connected to the connecting ring 111, a gear rotatably connected to the connecting ring 111, and a large gear ring rotatably connected to the connecting ring 111. The large gear ring and the connecting ring 111 are coaxially arranged, the driving magnet is fixed on the large gear ring, and the gear and the large gear ring are meshed. The scraper is configured to be made of iron material, and then the driving magnet is adsorbed on the scraper. At this time, the rotation of the large gear ring can drive the scraper to rotate, thereby cleaning the impurities on the inner wall of the furnace.

[0047] The implementation principle of a sintering furnace furnace cleaning device in an embodiment of the present application is: when the furnace needs to be cleaned, the vacuum box in the furnace is removed, and then the mounting frame 01 is pushed to move to the opening of the sintering furnace, and the cleaning ring 11 is driven to move by the driving component 02. At this time, the elastic abutment sheet 31 and the arc-shaped rubber sheet 32 ​​are not abutted against the inner wall of the furnace. As the cleaning ring 11 moves, the impurities are in the suction channel 05, and then the suction channel 05 is closed by adjusting the component 3, and the impurities in the suction channel 05 are cleaned by the adsorption component 2, and finally the powdered impurities are squeezed by the extrusion component 7, and the agglomerated impurities enter the collection box 61 under the action of the discharge port 64, which is convenient for subsequent detection.
