Problems solved by technology

[0003] The technical problem to be solved by the present invention is that the commonly used roller shuttle kiln burns the combustion gas incompletely, the temperature deviation is large, the roller is easy to bend, the finished product rate of the roller is low, and the production efficiency is low. It provides a method to reduce the bending of the roller, Fume exhaust method of shuttle kiln with high roller straightness and high yield

Embodiment Construction

[0013] Such as figure 2 and image 3 As shown, in the present invention, at least one partition 4 is laid above the kiln car platform 1 and the flue opening 2, and at least one adjusting air groove 3 is arranged between the partitions.

[0014] There are 9 partitions 4, and at least 2 adjustment air grooves 3 are formed between the partitions 4 and the partitions, and between the partitions and the furnace wall 5 horizontally and vertically.

[0015] The partition 4 is arranged above the kiln car platform 1 and the flue opening 2 above 100mm.

[0016] The separator 4 is a silicon carbide bonded silicon nitride separator.

[0017] The thickness of the separator 4 is 30mm.

[0018] figure 2 Among them, the C direction is the air flow direction when the air flow of the present invention is discharged from the lower part of the kiln, and the air flow on the upper part of the partition vertically enters the gap between the partition 4 and the partition, and between the partit...

Abstract

The invention discloses a smoke discharge method of a shuttle kiln, in particular relates to a smoke discharge method for a shuttle kiln. The technical problems to be solved are insufficient combustion of combustion gas, large temperature deviation, easy bending of rollers, low yield of the rollers and low production efficiency in a traditional roller shuttle kiln. At least one spacing plate is laid above a kiln car table board and a smoke flue outlet; and at least one adjusting wind groove is formed between the spacing plates. The smoke discharge method of the shuttle kiln improves the direction of airflows in the kiln, reduces the influence on the rollers, and improves the straightness of the rollers; and meanwhile, the spacing plates enable the kiln pressure and temperature above combustion chamber spacing plates to become more uniform, so that the sintering and size uniformity of the rollers are improved.

Description

technical field [0001] The invention relates to a smoke exhaust method, in particular to a smoke exhaust method for a shuttle kiln. Background technique [0002] The design requirements of the shuttle kiln are to achieve complete combustion within the effective volume, and the temperature deviation does not exceed ±2°C. Commonly used roller shuttle kilns are often large in size, reaching 100 cubic meters, with an inner width of 3500mm and a height of 5250mm. To achieve complete combustion in such a large shuttle kiln, the temperature deviation should not exceed ±2°C. The most critical thing is to It is a very difficult technology to ensure that the airflow formed by the combustion gas is minimized when it is discharged from the lower part of the kiln, and it is very difficult to prevent the rolls from being bent by the airflow in a high-temperature soft state, resulting in a low yield of the rolls and affecting production efficiency. . At present, when the airflow formed b...
