Abstract
The invention discloses a combined fixed fire grate segment to solve the problems that according to an existing fixed fire grate segment, due to the fact that an integrated structure is adopted, a fire grate needs to be integrally replaced during maintaining, and the repairing and maintaining cost of fire grate equipment is high. The combined fixed fire grate segment mainly comprises a plate sheet, a fixing shaft and a scraper blade arranged on the lower side of the plate sheet. A fixing rod is arranged on the lower side of the plate sheet. The fixing rod is located on the lower side of the scraper blade and plays a role in supporting the scraper blade. The combined fixed fire grate segment is characterized in that the plate sheet is composed of a fixing piece and an adjusting piece, the adjusting piece is stacked on the upper side of the fixing piece, and an adjusting gap is arranged at the end of the adjusting piece; the adjusting gap is provided with an adjusting bolt, the adjusting piece can move through the adjusting bolt, and therefore the bad effect on equipment running of an abrasion gap is offset; the service life of the equipment is further prolonged, and the running cost of a fire grate incinerator is reduced.
Description
Technical field
The present invention relates to the fixed grate of incinerator, especially relate to a kind of combined type fixed grate film.
Background technology
Fire grate segment (also known as fire grate watt, fire grate) is a large amount of parts used in grate incinerator, plays a part to support, stir and transmit the solid combustible material in incinerator.Fire grate segment work in an environment of high temperature, can reach 350 DEG C ~ 450 DEG C usually.In order to improve high temperature resistant, wear-resistant, the corrosion resistant performance of fire grate segment, usually make with the heat-resisting alloy cast steel that price is higher.In actual use, fire grate segment is except inevitable high-temperature oxydation and heat erosion, and wearing and tearing become the principal mode that fire grate segment lost efficacy.Particularly need the fire grate segment overturn, due to upset, the wearing and tearing of fire grate segment are particularly outstanding.
Existing fixed grate film is integral type structure, and after being arranged on the fixed axis of transmit bed, its position is just fixed.Once after the boss wearing and tearing at tilting bar arc surface or fixed grate film rear portion, the gap width between tilting bar and fixed grate film is caused to increase, increase causing the quantity of slag that falls at this position and affect the normal work of fire grate further, need integral replacing during maintenance, cause the defects such as replacing fire grate bar cost is high, equipment operating cost is high.
