A continuous integrated sintering furnace

Abstract

The invention relates to the field of sintering furnace equipment, in particular to a continuous integrated sintering furnace. At least four burning-resistant walls which are distributed at intervalsalong a straight line are arranged in a furnace body, all the burning-resistant walls are used for separating the inner space of the furnace body into a low-temperature degreasing chamber, a sinteringchamber and a cooling chamber, wherein transverse grooves are formed in the middle section area of all the burning-resistant walls, a sealer is arranged on one side, far away from the front end of the furnace body, of each burning-resistant wall, all the sealers correspond to the transverse grooves at the correspond positions respectively, a stepping type conveying device is further arranged in the furnace body, the stepping type conveying device comprises a conveying rolling belt, the upper layer area of the conveying rolling belt penetrates through all the transverse grooves in a horizontalposture in sequence, a plurality of openings which are arranged at intervals along the conveying direction of the conveying rolling belt are formed in the outer surface of the conveying rolling belt,a plurality of anti-burning bricks with hollow structures are arranged on the inner surface of the conveying belt, and all the baking-resistant bricks correspond to all the openings in a one-to-one mode. According to the continuous integrated sintering furnace, the sintering operation can be carried out on a large-size workpiece, and the sealing performance is guaranteed in the working process.

Description

technical field [0001] The invention relates to the field of sintering furnace equipment, in particular to a continuous integrated sintering furnace. Background technique [0002] Sintering is the main process for most ceramic materials and powder metallurgy materials to change from powder to products. The essence of sintering is that the powder green block is heated in an appropriate environment or atmosphere, and through a series of physical and chemical changes, the powder particles are fused together, the strength and density of the green block increase rapidly, and various physical properties and mechanical properties of the product are obtained. improve.

Problems solved by technology

[0003] Continuous sintering furnace is a kind of sintering furnace. This kind of furnace has the characteristics of large production capacity, uniform product quality, high thermal efficiency, and convenient operation. The general structure of the existing continuous sintering furnace is that there are several Composed of degreasing chamber, preheating section, high-temperature sintering section and cooling discharge section, there are two problems in the existing continuous sintering furnace, one of which is poor sealing effect at the furnace mouth, which will cause heat energy to flow out The other is that the sealing effect between the aforementioned two adjacent chambers is also poor, which will cause large fluctuations in the degree of vacuum, the amount of protective gas, and the temperature in a single chamber, so that the quality and accuracy of product sintering cannot be improved.

[0004] According to the above problems, after retrieval: Chinese Patent No. CN201510607178.7 discloses a belt-type atmosphere sintering furnace for continuous production of lithium iron phosphate cathode materials. The sintering furnace has good sealing performance, but it is only suitable for the processing of micro-sized materials , for the sintering of some large pieces, this structure cannot play a good sealing role, and at the same time, the large furnace body will also cause excessive equipment investment costs
