Abstract
The utility model discloses a biomass boiler grate. The biomass boiler grate comprises a transmission shaft, a movable frame, a fixed frame, pushing pieces and several groups of burning pieces. The movable frame, the pushing pieces and the burning pieces are all arranged in the fixed frame. Across the movable frame, the transmission shaft is connected with the front end of the movable frame. Each pushing piece consists of a movable pushing piece and a fixed pushing piece. The movable pushing pieces are fixed on the movable frame, and the fixed pushing pieces are fixed on the fixed frame. The movable pushing pieces are located in front of the fixed pushing pieces, and the burning pieces are placed behind the fixed pushing pieces in order. Each burning piece comprises a movable burning piece and a fixed burning piece. The movable burning pieces are fixed on the movable frame, and the fixed burning pieces are fixed on the fixed frame. The movable burning pieces are located in front of the fixed burning pieces. Through reciprocating motion of the transmission structure in work, automatic feeding and deslagging of the biomass boiler grate can be realized.
Description
Technical field
The utility model relates to a kind of biomass boiler fire grate.
Background technology
Biomass boiler is as a kind of novel material equipment, and its design differs greatly with coal-burning boiler: biomass material is larger with the coal burning property difference on the one hand, and living beings are a kind of low heat value, high-volatile fuel, and its calorific value is only for marking coal about half; And fugitive constituent can up to more than 70%, be 2～3 times of at present general bituminous coal.Living beings are easy to burning on the other hand, and thermal release is rapid, and fugitive constituent burning release heat occupies about 90% of its total release heat.The burning of raw material in boiler is that chamber design is relevant on the one hand, and be relevant with the fire grate design on the other hand, and for this special material, general coal boiler grate design parameter can't satisfy its combustion characteristics.
Biomass boiler is a kind of novel power equipment of environmental protection and energy saving, and market prospects are huge, therefore, in conjunction with present actual conditions, biomass boiler fire grate form and structural design is proposed new argument and structure, and the application of biomass boiler is significant.
Summary of the invention
For above-mentioned prior art, the utility model provides a kind of biomass boiler fire grate.
The utility model is achieved through the following technical solutions:
A kind of biomass boiler fire grate, comprise power transmission shaft, moving framework, quiet framework, pushing sheet and some groups of fire plates, wherein, moving framework, pushing sheet and fire plate all are positioned at quiet framework, power transmission shaft passes quiet framework and be connected (during work, power transmission shaft moves back and forth) with moving frame front end under driving motor drives; Pushing sheet is comprised of pusher moving plate and pusher still, and the pusher moving plate is fixed on the moving framework, and the pusher still is fixed on the quiet framework, and the pusher moving plate is positioned at pusher still front side; Some groups of fire plates are sequentially arranged in pusher still rear side, and fire plate is comprised of burning moving plate and burning still, and the burning moving plate is fixed on the moving framework, and the burning still is fixed on the quiet framework, and the burning moving plate is positioned at burning still front side.
Described pushing sheet is blind plate, and fire plate air draught rate is 30%.
Preferably, described fire plate has 5 groups.
Biomass boiler fire grate of the present utility model is for a kind of thermic load that is adapted to is not more than 6 * 10
5The small-sized biomass normal-pressure hot-water boiler fire grate of Kcal/h, this fire grate structure adopt high ventilation rate design; Operation principle is: in service, power transmission shaft is done straight reciprocating motion at horizontal plane under driving motor drives, the moving framework of drive and pusher moving plate, burning moving plate move reciprocatingly, the pusher moving plate promotes fuel to the pusher still, and then on fire plate, fire plate bottom air distribution is with ignited fuel, along with the reciprocating motion of burning moving plate on the burning still, fuel is pushed forward while burning, when fuel is pulled to the fire grate afterbody, the fuel after-flame, and be pulled in the ash slag box, realized automatic removing lime-ash.
Biomass boiler fire grate of the present utility model, its fire grate segment can be divided into fire plate and pushing sheet according to the function difference, can be divided into moving plate and still according to the state of fire grate segment.Fire plate ventilation rate 30%, enough air capacities when guaranteeing the biological particles burning.Pushing sheet is not opened the air port, is blind, has guaranteed that air leaks out, so that the wind that enters in the burner hearth all participates in burning.All fire plate physical dimensions are unified, and are simple in structure, are convenient to change.In fire grate structure, with raw material contact furnace screening in the feed bin be pushing sheet, pushing sheet is designed to 1 moving plate and 1 still, then is to be right after fire plate, the sound sheet is staggered.Moving plate is fixed on moving framework, moves back and forth under driving motor drives; Still is fixed on quiet framework.By the reciprocating motion of drive mechanism, automatic feed and self-skimming have been realized.

The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described.
A kind of biomass boiler fire grate, comprise power transmission shaft 1, moving framework 7, quiet framework 6, pushing sheet 8 and some groups of fire plates 9, as shown in Figure 1 and Figure 2, wherein, moving framework 7, pushing sheet 8 and fire plate 9 all are positioned at quiet framework 6, power transmission shaft 1 passes quiet framework 6 and be connected (during work, power transmission shaft 1 moves back and forth) with moving framework 7 front ends under driving motor drives; Pushing sheet 8 is comprised of pusher moving plate 2 and pusher still 3, and pusher moving plate 2 is fixed on the moving framework 7, and pusher still 3 is fixed on the quiet framework 6, and pusher moving plate 2 is positioned at pusher still 3 front sides; Some groups of fire plates 9 are sequentially arranged in pusher still 3 rear sides, and fire plate 9 is comprised of burning moving plate 4 and burning still 5, and burning moving plate 4 is fixed on the moving framework 7, and burning still 5 is fixed on the quiet framework 6, and burning moving plate 4 is positioned at burning still 5 front sides.
Described pushing sheet 8 is blind plate, and fire plate 9 air draught rates are 30%.
During use, biomass boiler fire grate of the present utility model is placed the biomass boiler burner hearth, operation principle is: in service, power transmission shaft 1 is done straight reciprocating motion at horizontal plane under driving motor drives, drive moving framework 7 and pusher moving plate 2, burning moving plate 4 moves reciprocatingly, pusher moving plate 2 promotes fuel to pusher still 3, and then on fire plate 9, fire plate 9 bottom air distributions are with ignited fuel, and along with the reciprocating motion of burning moving plate 4 on burning still 5, fuel is pushed forward while burning, when fuel is pulled to the fire grate afterbody, the fuel after-flame, and be pulled in the ash slag box, realized automatic removing lime-ash.
Although above-mentionedly by reference to the accompanying drawings the specific embodiment of the present utility model is described; but be not the restriction to the utility model protection domain; one of ordinary skill in the art should be understood that; on the basis of the technical solution of the utility model, those skilled in the art do not need to pay various modifications that creative work can make or distortion still in protection domain of the present utility model.
