Abstract
The invention discloses an anti-abrasion reciprocating grate bar supporting structure. A movable grate bar and a fixed grate bar are connected with a movable stand and a fixed stand in a clamped mode respectively. The movable stand and the fixed stand are respectively connected with a positioning plate set corresponding to the grate bars. The distance between two positioning plates of the positioning plate set is a little larger than the thickness of a rib plate of each grate bar; the rib plates of the grate bars can be inserted between the two positioning plates and can prevent the movable grate bar or the fixed grate bar from moving left and right, the gap between the grate bars keeps uniform, the phenomenon of unsmooth ventilation caused by coal leakage and blocking of ventilation holes can not occur, fuel is combusted more uniformly and more completely, and accordingly combustion efficiency is improved. The movable grate bar and the fixed grate bar are respectively supported through an independent supporting rod, abrasion and friction between the movable grate bar and the fixed grate bar are prevented, the service life of the reciprocating grate bars is prolonged, the number of blowing-out times of a boiler is reduced, maintenance cost of the boiler is reduced, and use efficiency of the boiler is improved.
Description
Technical field
The present invention relates to a kind of boiler grate, particularly relate to a kind of boiler reciprocating grate device.
Background technology
Fire grate banks up solid fuel be effective the parts of burning in boiler or industrial furnace, and its fixed grate film and movable furnace grate plate interval laminate into stair-stepping grate surface, and fuel moves on grate surface.Its effect is progressively transported to slag-drip opening by the fuel slug fallen in feed bin, and make it in the process of transporting, carry out Thorough combustion.Traditional reciprocal grate structure there is many disadvantages, first be, working under hard conditions of reciprocal grate, relative motion is there is between fire grate, due to the impact of high-temperature fuel layer, blocking easily appears in fire grate segment, the phenomenon of distortion, mutual wearing and tearing between fixed grate film and movable furnace grate plate, make the service life of fire grate segment short, need often change, add maintenance cost and the time of boiler, decrease the running time of boiler, user have to increase the service life fire grate segment do very thick extend wearing and tearing time, the furnace outage time that reduces boiler; The second, fire grate segment installation accuracy is low, and the gap between fire grate segment is uneven, and produce leakage coal, air vent blocking causes ventilation freely, cause the burning of fuel uneven, some places burning is abundant not, efficiency of combustion decline.Owing to there is above-mentioned shortcoming; along with the development of boiler combustion technology; coal-fired boiler seldom uses reciprocal grate structure; but along with the change of boiler oil structure; such as use the fuel of the high-moisture such as living beings, house refuse; because reciprocating-grate boiler is applicable to domestic waste, trade waste, biomass fuel, face today of exhausted crisis gradually at the energy, again for people pay close attention to again.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, a kind of long service life is provided, do not need frequent antiwear reciprocating furance row supporting construction of keeping in repair.
The technical scheme that the present invention is adopted for achieving the above object is:
A kind of antiwear reciprocating furance row supporting construction, comprise movable furnace grate plate, fixed grate film, movable shelf rest and fixing shelf rest, movable furnace grate plate and fixed grate film are connected on movable shelf rest and fixing shelf rest respectively, it is characterized in that: described movable shelf rest is connected with the location-plate group corresponding with movable furnace grate plate, location-plate group is made up of two location-plates, and the distance between two location-plates is slightly larger than the thickness of movable furnace grate plate gusset, described fixing shelf rest is connected with the location-plate group corresponding with fixed grate film, location-plate group is made up of two location-plates, distance between two location-plates is slightly larger than the thickness of fixed grate film gusset, the gusset of movable furnace grate plate or fixed grate film can insert between two location-plates of location-plate group, control gap between two location-plates in less scope, can prevent movable furnace grate plate or fixed grate film from moving left and right, thus the gap uniformity between maintenance fire grate segment, be unlikely to produce and leak material, air vent blocks the phenomenon causing ventilation not smooth, make the burning of fuel evenly, more abundant, and then raising efficiency of combustion.Described location-plate has through hole, and support bar can penetrate in this through hole; The middle part of movable furnace grate plate and fixed grate film is equipped with support limit hole, and described support limit hole can be connected on support bar.
The good effect that the present invention compared with prior art has is:
Movable furnace grate plate and fixed grate film are respectively by independent they sup-port, prevent from producing wearing and tearing and frictional force between movable furnace grate plate and fixed grate film, improve the service life of reciprocating furance row, decrease the blowing out number of times of boiler, reduce the maintenance cost of boiler, improve the service efficiency of boiler.Eliminate the frictional force between movable furnace grate plate and fixed grate film simultaneously, decrease resistance when fire grate promotes, decrease the power of reciprocal grate pushing motor.Movable furnace grate plate, fixed grate film are limited by location-plate, make the gap uniformity between fire grate segment, are unlikely to produce to leak coal, air vent and block the phenomenon causing ventilation not smooth, make the burning of fuel evenly, more abundant, and then raising efficiency of combustion.
