Abstract
The invention discloses a kind of antiwear reciprocating furance row supporting construction.Its movable furnace grate plate and fixed grate film are connected on movable shelf rest and fixing shelf rest respectively, being respectively connected with the location-plate group corresponding with fire grate segment on movable shelf rest, fixing shelf rest, the distance between two location-plates of location-plate group is slightly larger than the thickness of fire grate segment gusset;The gusset of fire grate segment can be inserted between two location-plates, it is possible to prevent movable furnace grate plate or fixed grate film to move left and right, thus the gap uniformity between holding furnace screening, be unlikely to produce leakage coal, air vent blocking causes the most smooth phenomenon of ventilating, make the burning of fuel evenly, more fully, and then improve efficiency of combustion.Movable furnace grate plate and fixed grate film are respectively by single they sup-port, prevent from producing between movable furnace grate plate and fixed grate film abrasion and frictional force, 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.
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 is to bank 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 stepped grate surface, and fuel moves on grate surface.Its effect is progressively to be transported to slag-drip opening by the fuel slug fallen in feed bin, and makes it fully burn during transporting.Many disadvantages is had in traditional reciprocal grate structure, first it is, working under hard conditions of reciprocal grate, relative motion is there is between fire grate, impact due to high-temperature fuel layer, blocking easily occurs in fire grate segment, the phenomenon of deformation, mutual abrasion between fixed grate film and movable furnace grate plate, the service life making fire grate segment is short, need to often change, and adds maintenance cost and the time of boiler, decrease the operation time of boiler, user have to increase the service life fire grate segment be made the thickest extend abrasion time, the furnace outage time that reduces boiler;Second, fire grate segment installation accuracy is low, and the gap between fire grate segment is uneven, and generation leakage coal, air vent blocking cause ventilation smooth, and the burning causing fuel is uneven, and some places burn abundant not, and efficiency of combustion declines.Owing to there is disadvantages mentioned above; development along with boiler combustion technology; coal-fired boiler has been rarely employed reciprocal grate structure; but it is as the change of boiler oil structure; such as use the fuel of the high-moisture such as biomass, house refuse; because reciprocating-grate boiler is applicable to domestic waste, trade waste, biomass fuel, gradually face today of exhausted crisis at the energy, again pay close attention to for people again.
Summary of the invention
It is an object of the invention to overcome the deficiencies in the prior art, it is provided that a kind of service life length, need not antiwear reciprocating furance row supporting construction of often keeping in repair.
The present invention be the technical scheme is that for achieving the above object
A kind of antiwear reciprocating furance row supporting construction, including 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: connecting on described movable shelf rest has 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;Connect on described fixing shelf rest and have 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 be inserted between two location-plates of location-plate group, control the gap between two location-plates in less scope, it is possible to prevent movable furnace grate plate or fixed grate film to move left and right, thus the gap uniformity between holding furnace screening, it is unlikely to produce material leakage, air vent blocking causes the most smooth phenomenon of ventilating, make the burning of fuel evenly, more abundant, and then raising efficiency of combustion.Having through hole on described location-plate, 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 single they sup-port, prevent from producing between movable furnace grate plate and fixed grate film abrasion and frictional force, 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 leakage coal, air vent blocking causes the most smooth phenomenon of ventilating, make the burning of fuel evenly, more abundant, and then improve efficiency of combustion.
