Abstract
The utility model relates to a suspension combustion layered coal supply machine for belt type coal stirring boilers, which mainly solves the problems that coal is leaked among coal stirring rollers, the runtime is longer, and coal powders on a coal supporting board are increased and form blocks to tightly contact the lower arc of coal feeding rollers, even generate journal sticking, and influence the regular run of production, etc. The utility model comprises a machine body of a coal conveying machine, a coal stirring driving chain wheel, a coal stirring driven chain wheel, a sifter, a transmission mechanism, etc. The utility model is characterized in that the coal stirring driving chain wheel and the coal stirring driven chain wheel are respectively engaged on both ends of a chain on the chain a flexible coal conveying belt is clamped and connected through a connecting plate and a coal stirring plate, wherein, the coal stirring plate is uniformly distributed and assembled on the upper part of the flexible coal conveying belt. The utility model has the advantages that the coal supply machine thoroughly eliminates the phenomenon of coal leakage among coal stirring rollers, leaves out a coal carrying board, throws combustion coal into boilers smoothly, has small running resistance, has a large coal stirring area, reduces production cost, and can be conveniently maintained.
Description
Technical field
The utility model belongs to a kind of coal conveyor tool, and particularly a kind of belt is dialled coal burning boiler suspension combustion decked coal-feeding machine.
Background technology
Some industrial furnaces of China are in order to improve coal-fired efficiency of combustion at present; adopted " even laminating combustion technology "; and by double-roll type layering coal supply apparatus coal supply; but the main deficiency that exists is to broadcast the coal of leakage phenomenon is arranged between the coal roller; leak the coal problem between roller in order to solve; improved afterwards equipment is provided with holder coal plate broadcasting coal roller bottom; but running time is long slightly; coal dust increases on the holder coal plate; if coal is humidity relatively, or the hard fixing bulk of coal dust formation that all can make on the holder coal plate with the humid air, contact tighter with the round bottom of coal sowing roller arc; produce frictional force; increase motor load, all can produce to a certain degree damage, severe patient even the seize phenomenon takes place electric machine main shaft and reductor; the shutdown maintenance of having to influences the ordinary production operation.
The utility model content
The purpose of this utility model provides a kind of belt and dials coal burning boiler suspension combustion decked coal-feeding machine, and thoroughly elimination is broadcast and leaked the coal phenomenon between the coal roller, and cancellation holder coal plate makes coal-fired input smooth and easy, and running resistance is little, and it is big to broadcast the coal area, reduces production costs, easy to maintenance.
The purpose of this utility model is achieved in that it comprises the coal conveyor body, dials the driving and driven sprocket wheel of coal, sifter, transmission device etc., it is characterized in that: dial the two ends of the driving and driven sprocket engagement of coal at chain, clamp the flexible coal transportation belt of connection by gusset piece and coal moving plate on chain, coal moving plate is in the uniform assembling in the top of flexible coal transportation belt.Operation principle: when the coal that drops into is fallen on the coal moving plate of flexible coal transportation belt, by the operation of flexible coal transportation belt, coal is broadcast on the sifter, sifter makes the coal on the fire grate present bulk below, the superincumbent distribution of coal dust in addition layering of coal.
Advantage of the present utility model: owing to adopt flexible coal transportation belt, thoroughly elimination is broadcast and is leaked the coal phenomenon between the coal roller, and cancellation holder coal plate makes coal-fired input smooth and easy, and running resistance is little, and it is big to broadcast the coal area, reduces production costs, easy to maintenance.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the A-A cutaway view of Fig. 1.
Fig. 3 is the flexible coal transportation belt structural representation of assembling on chain.
Fig. 4 is the local enlarged diagram of chain and flexible coal transportation belt draw bail.
The specific embodiment
See Fig. 1-4, concrete structure is as follows: the top of coal conveyor body 2 is coal feeding hole 1, and drive sprocket 3-1 drives by driving shaft 5, and the driving wheel on the driving shaft 5 connects regulating wheel 6 by driving-belt.Pulling out coal drive sprocket 3-1 is connected by driving chain 9 with group coal driven sprocket 3-2, uniform affixed installing plate 10 on driving chain 9, flexible coal transportation belt 8 is fixed on the installing plate 10 by uniform metal coal moving plate 7 and connector, and flexible coal transportation belt 8 can adopt sandwich rubber strip, nylon tapes such as folder cloth, folder steel wire.Flexible coal transportation belt 8 is below assembling sifter 9 tiltedly, and the below of sifter 9 is fire grates of operation.
