Description
Technical field
The utility model relates to fire grate technical field, especially a kind of reciprocal grate base.
Background technology
Fire grate banks up solid fuel be effective the parts of burning in boiler or industrial furnace.Its effect is also progressively transported to slag-drip opening by the coal cinder added under coal bunker decline, and make it in the process of transporting, carry out Thorough combustion.Traditional reciprocal grate in the course of the work, 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, makes fire grate beam unbalance stress, produces additional moment of torsion, cause the connection between fire-grating frame and fire grate beam to be destroyed, affect the normal operation of boiler.Trace it to its cause, mainly existing reciprocating furnace is toward multiple bank complex structure, and the driving force of motion is inadequate, easily makes fire grate segment block, finally causes the connection between fire-grating frame and fire grate beam to be destroyed.
Utility model content
The technical problems to be solved in the utility model is: in order to solve existing reciprocating furnace toward multiple bank complex structure, the driving force of motion is inadequate, fire grate segment is easily made to block, finally cause the problem that the connection between fire-grating frame and fire grate beam is destroyed, the utility model provides a kind of reciprocal grate base, and by designing a kind of simple fire grate thrust unit, many group fire grate thrust units drive the motion of fire grate simultaneously, effectively by coal crusher, higher combustion rate can be ensured.
The utility model solves the technical scheme that its technical problem adopts: a kind of reciprocal grate base, comprise two fire grate side seats, between two fire grate side seats, step has been staggered multiple movable furnace grate plate and fixed grate film, described fixed grate film is fixed between two fire grate side seats by stationary furnace bracket, described movable furnace grate plate is fixed between two fire grate side seats by some groups of fire grate thrust units, and described fire grate thrust unit comprises
Oil cylinder, is fixed between two fire grate side seats, below movable furnace grate plate and fixed grate film,
Slurcam, the plate face of slurcam is parallel with the row face that fixed grate film is formed with movable furnace grate plate, slurcam upper surface be provided with several vertical directions, for the stationary furnace bracket fixing with movable furnace grate plate, lower surface is provided with two for supporting the platform of slurcam
Some rollers are provided with between two fire grate side seats, the platform of described slurcam lower surface is placed on roller, be provided with a drive plate in the middle part of described slurcam, the piston rod of described drive plate and oil cylinder is hinged, and the stationary furnace bracket of slurcam upper surface is fixedly connected with movable furnace grate plate.
Particularly, the cylinder barrel of described oil cylinder is hinged between two fire grate side seats.
In order to make the coal cinder sufficient combustion of stoker surface, described fixed grate film comprises horizontal part and sidepiece, and described horizontal part and/or side surfaces all offer the through hole being convenient to fixed grate film heat radiation.
Particularly, described through hole is circular port or kidney ellipsoid hole.
The beneficial effects of the utility model are: a kind of reciprocal grate base that the utility model provides, by designing a kind of simple fire grate thrust unit, many groups fire grate thrust unit drives the motion of fire grate simultaneously, effectively by coal crusher, can ensure higher combustion rate; Meanwhile, the horizontal part of fixed grate film and/or side surfaces all offer the through hole being convenient to fixed grate film heat radiation, can make the further Thorough combustion of coal cinder, can also extend the service life of fixed grate film simultaneously.
