Horizontal rotary furnace decoking mechanism

Abstract

The invention discloses a horizontal rotary kiln decoking mechanism which comprises a rotating shaft, a center support and a scraping and touching piece. The rotating shaft horizontally penetrates through the center of the rotary furnace inner cylinder, and two ends extend out of the rotary furnace inner cylinder; the plurality of central brackets are arranged on a rotating shaft of an inner cylinder of the rotary furnace, one end of each central bracket is fixedly connected with the rotating shaft, and the other end of each central bracket is fixedly connected with the inner wall of the inner cylinder of the rotary furnace and rotates along with the rotation of the inner cylinder of the rotary furnace; one end of the scraping and colliding piece is movably arranged on the rotating shaft between the two center supports in a sleeving mode and rotates around the rotating shaft, the other end of the scraping and colliding piece extends outwards to form a scraping and colliding edge, and the scraping and colliding edge is matched with the inner wall of the inner cylinder of the rotary furnace. The horizontal rotary kiln decoking mechanism is applied to decoking of an inner barrel of a pyrolysis rotary furnace, decoking of the inner barrel of the rotary furnace is achieved without external power, meanwhile, the reaction temperature of materials in the inner barrel of the rotary furnace is directly detected, the structure is simple, and cost is saved.

Description

technical field [0001] The invention relates to the technical field of pyrolysis rotary kiln equipment, in particular to a coke cleaning mechanism of a horizontal rotary kiln. Background technique [0002] At present, the drying kilns and pyrolysis carbonization kilns of external heat horizontal rotary kilns in industrial applications often encounter the problems of coking on the inner wall of the rotary cylinder and the inability to directly monitor the temperature of the materials in the cylinder. [0003] First of all, when using an externally heated rotary kiln for continuous pyrolysis of organic matter, the anaerobic pyrolysis environment inside the kiln should be strictly separated from the external aerobic environment. On the inner cylinder wall, the subsequent heat transfer and material reaction are seriously affected; when coking is formed in the rotating inner cylinder wall, add some inert substances such as sand and steel balls to the cylinder to clean up, or inst...

Problems solved by technology

At the same time, by setting the temperature sensor on the end of the central support close to the inner wall of the rotary furnace, the central support and the rotating shaft are hollow structures, the temperature sensor connection line is connected to the external equipment through the hollow structure, and the temperature signal is transmitted through the temperature sensor connection line. It can directly detect the reaction temperature of the material in the inner cylinder of the rotary furnace, which solves the problem that the temperature of the material in the inner cylinder of the rotary furnace cannot be directly monitored
