A chain grate machine with adjustable axial clearance

Abstract

The invention discloses a chain grate machine with adjustable axial gap, which comprises a small shaft, the top and bottom of the small shaft are welded with spacer tubes, and the ends of the spacer tubes away from the small shaft are sleeved with The inner sleeve of the chain link, the end of the inner sleeve of the chain link away from the small shaft is integrally formed with a chain link, the body of the chain link is provided with a first screw hole in the transverse direction, and the ends of the chain links on the left and right sides are connected by screws There is a side plate, and the front end of the side plate is sleeved on the outer wall of the small shaft. The end of the side plate away from the chain link is in contact with a backing plate mechanism. The backing plate mechanism includes a connecting housing, and the connecting housing is close to the side There is an opening on one side of the plate, and a gasket is arranged on the opening, and a connecting column is bonded between the gasket and the middle part of the connecting housing, and the gasket and the connecting housing are evenly connected by screws. Spring, the axial gap of the device remains constant after long-term use, there will be no leakage of a large number of raw balls, the output of finished balls is stable, and the production cost is reduced.

Description

technical field [0001] The invention relates to the technical field of grate machines, in particular to a grate machine with adjustable axial clearance. Background technique [0002] The grate machine is the key equipment for pellet production, responsible for preheating, drying and roasting of raw pellets, and then the unqualified pellets will be screened out from the gap between the grate plates. It is a set of mature thermal engineering The long-term operation of the equipment and the grate machine at high temperature has caused the tensile deformation of the small shaft, the wear of the section of the distance tube and the inner sleeve of the chain link, which shows that the overall axial clearance of the device is large and the material leakage is serious. [0003] However, the existing device has the problem that the axial gap of the device will become larger after a long time of use, causing a large amount of raw balls to leak out, resulting in a reduction in the outp...

Problems solved by technology

[0004] In view of this, aiming at the deficiencies of the prior art, the purpose of the present invention is to provide a chain grate with adjustable axial clearance, so as to solve the problem that the axial clearance of the device proposed in the background technology will become larger after a long time of use and cause a large number of Leakage of raw balls, resulting in a reduction in the output of finished balls and an increase in production costs
