Problems solved by technology

The biggest problem with this structure is the sealing of the moving shaft, because the pyrolysis furnace and other equipment have high requirements on the sealing performance of the pyrolysis furnace. If the existing moving grate installation structure is used, the sealing performance is not good enough, and air is easy to enter the furnace body. , affecting the quality of the pyrolysis reaction

Abstract

The invention discloses a seal structure of a motive shaft of a high temperature furnace. The seal structure comprises a furnace body, and a notch used for accommodating the motive shaft is formed inthe furnace body; a mounting block matched with the notch is arranged on the furnace body; the mounting block and the edge of the notch are hermetically connected; a through hole groove used for allowing the motive shaft to slide is formed in the mounting block; the motive shaft is inserted in the through hole groove; the end, arranged in the furnace body, of the motive shaft is connected with a seal plate; the seal plate and the mounting block are hermetically connected through a first sealing element; and the motive shaft and the seal plate are hermetically connected through a second sealingelement. According to the seal structure, the motive shaft is always sealed with the furnace body during the moving process, a relatively good sealed environment is provided for the high temperaturefurnace, and utilization requirements are well met.

Description

technical field [0001] The invention relates to the field of sealing structures, in particular to a moving shaft sealing structure of a high-temperature furnace. Background technique [0002] High temperature furnace is a kind of equipment used for high temperature reaction, such as pyrolysis furnace, reforming furnace, etc. For equipment such as pyrolysis furnaces, in order to achieve sufficient pyrolysis and turnover of waste materials, a movable grate is generally provided, and the support of the grate is completed by a moving shaft, which is interspersed in the furnace body, and can Slide back and forth. The biggest problem with this structure is the sealing of the moving shaft, because the pyrolysis furnace and other equipment have high requirements on the sealing performance of the pyrolysis furnace. If the existing moving grate installation structure is used, the sealing performance is not good enough, and air is easy to enter the furnace body. , affecting the quali...
