Sintering-atmosphere loss-free obstacle-removing device for ferrite-sintering furnace

Abstract

The invention relates to a sintering-atmosphere loss-free obstacle-removing device for a ferrite-sintering furnace, which belongs to the technical field of electronic-product sintering furnaces. The sintering-atmosphere loss-free obstacle-removing device comprises a sealing joint, a sealing cover, a protecting cover and an obstacle-removing sleeve, wherein one end of the sealing joint extends to form a narrow shrinkage-pipe segment; the sealing cover is matched with the sealing joint; the protecting cover is connected with the sealing joint at a position corresponding to the sealing cover; and the obstacle-removing sleeve is provided with a first sleeve opening, a second sleeve opening and a material bag which is positioned between the first sleeve opening and the second sleeve opening, the first sleeve opening is tied and fixed with the arm of an obstacle-removing person when obstacles are removed, the second sleeve opening is hermetically fixed with the narrow shrinkage-pipe segmentwhen the obstacles are removed, a protective-gas filling opening is connected onto the material bag and the lateral part of the material bag in an extending mode, and the bag opening of the material bag is bound and sealed when the obstacles are removed. The sintering-atmosphere loss-free obstacle-removing device has the advantages that: protective gas can be prevented from escaping to the outside, the balance of a protective atmosphere in a hearth is ensured, and the sintering-atmosphere loss-free obstacle-removing device is favorable to guaranteeing the normal working of the sintering furnace.

Description

technical field [0001] The invention belongs to the technical field of sintering kilns for electronic products, and in particular relates to a non-loss troubleshooting device for sintering atmosphere of ferrite sintering kilns . Background technique [0002] As known in the industry, ferrite needs to be sintered in a kiln, and the sintering is carried out in a protective atmosphere. During the sintering process, it is necessary to ensure that the protective gas in the furnace is in a balanced state, otherwise it will affect the quality of the sintering, and even lead to scrapping in severe cases. Undoubtedly, whenever the furnace door of the inlet and outlet is opened once, it is inevitable that the protective gas in the furnace will escape, so that the atmosphere of the protective gas in the furnace will be out of balance, resulting in the aforementioned impact on quality and even results in scrapping. In this regard, it is solved by the "protective gas compensation de...

AI Technical Summary

Problems solved by technology

The current disposal method can only wait for the sintering furnace to stop working to clear the obstacles, which will affect the continuous production of the sintering furnace and waste energy

Therefore, it is necessary to equip ferrite sintering kilns with a reasonable troubleshooting device that can fully avoid the loss of the sintering atmosphere due to troubleshooting, but there is no corresponding technical inspiration in the published patents and non-patent literature. There is also no report of success in the industry, and the applicant has made a useful attempt for this reason, and the technical scheme to be introduced below is produced under this background
