A side sealing device for a heat treatment furnace

Abstract

The invention discloses a side sealing device of a thermal treatment furnace. The side sealing device of the thermal treatment furnace comprises a power device, a pull rod, a sealing groove, a sealing block, a tugging wheel assembly, a tugging wheel support, a rolling wheel carrier, a rolling wheel and guiding tracks. The side sealing device of the thermal treatment furnace drives the pull rod through an air cylinder, the strip-shaped sealing groove is formed in the pull rod, the sealing block for sealing a gap between a heating furnace and a furnace car is installed in the sealing groove to enable the sealing block to seal the gap, operation is convenient and quick, and the sealing effect is good. The guiding tracks are further fixed at the bottom of the sealing groove, and the rolling wheel fixed on the support and the tugging wheel assembly are further arranged in the guiding tracks on two sides, so that the effect that the side sealing device is movably connected with a furnace body is played. In addition, the service life is long, and the pneumatic sealing cost is low.

Description

technical field [0001] The invention relates to a sealing device, in particular to a side sealing device of a heat treatment furnace. Background technique [0002] The side sealing device of the heat treatment furnace is the side edge sealing device between the heat treatment furnace (also called the heating furnace) and the furnace car. In the name "Multi-station Heat Treatment Furnace", there is a gap between the bottom sides of the furnace when the furnace car is transported to the furnace body, and it needs to be sealed. However, the existing seal is generally sealed by a sand sealing groove, which is filled in the sealing groove. There is sand for sealing, but in this sealing structure, the sand is easy to fall, which affects the sealing effect, and the operation is inconvenient. Moreover, it needs to be manually filled with sand frequently. The operation is cumbersome and labor-intensive. The falling of sand also affects the working environment. The cost of secondary ...

Problems solved by technology

[0002] The side sealing device of the heat treatment furnace is the side edge sealing device between the heat treatment furnace (also known as the heating furnace) and the furnace car, such as the Chinese patent No. 2009202417540 applied by the applicant on December 11, 2009, the patent In the name "Multi-station Heat Treatment Furnace", there is a gap between the furnace car transported to the bottom of both sides of the furnace body, which needs to be sealed. However, the existing seals generally use sand sealing grooves for sealing, which are filled in the sealing grooves. There is sand for sealing, but with this sealing structure, the sand is easy to fall, affecting the sealing effect, and the operation is inconvenient, and it is often necessary to manually fill the sand, which is cumbersome and labor-intensive, and the sand falling also affects the working environment. The cost of sand transportation for secondary filling is high, and the sealing performance is relatively poor
