Abstract
The invention relates to the technical field of dry acetylene generation, provides a sealing structure of a stirring shaft of an acetylene generator, and aims at solving the problems that an existing stirring shaft is seriously abraded, troublesome to replace and high in replacement cost. The sealing structure comprises a stirring shaft rotationally connected with a stirring machine base, an insert bush which is arranged outside the stirring shaft in a sealing and sleeving mode and can synchronously rotate along with the stirring shaft, and a filler base which is located on the periphery of the insert bush and connected with the lower end of the stirring machine base, wherein a sealing filler is arranged between the insert bush and the filler base and is pressed through a filler gland connected with the filler base; the filler base is provided with a jacket; and the jacket is filled with circulating cooling water and used for cooling the sealing filler. According to the sealing structure of the stirring shaft of the acetylene generator provided by the invention, contact friction between the stirring shaft and the sealing filler is replaced with the insert bush, the friction part is cooled in a water cooling mode, the insert bush is small in abrasion, the service life of the sealing filler is long, convenience is brought to later overhaul, only the insert bush needs to be replaced, the cost is low, the maintenance period is short, and the acetylene gas output efficiency can be improved.
Description
technical field [0001] The invention relates to the technical field of dry acetylene generation, in particular to a sealing structure for a stirring shaft of an acetylene generator. Background technique [0002] The production process of dry acetylene is to react calcium carbide and water in the acetylene generator to generate acetylene gas, and then the acetylene gas enters the washing and cooling tower through the outlet of the gas phase for washing and cooling. Among them, the acetylene generator is its core equipment, and stirring is an important means in operation. The sealing of the stirring shaft is related to the safe operation, cost control and environmental sanitation of the whole device, so the sealing of the stirring shaft is very important in operation. [0003] At present, after long-term use of the stirring shaft of the acetylene generator, the sealing packing used to seal the stirring shaft and the mixer base directly rubs against the stirring shaft, resultin...
