Description

A kind of two hopper of boiler
Technical field:
The present invention relates to boiler plant field, more particularly to a kind of two hopper of boiler.
Background technology:
Because the proterties difference of biomass fuel and fire coal is very big, therefore can not be placed in same fuel hopper, in order to avoid Situations such as there is spontaneous combustion, so be typically all that different fuel hopper assembles different fuel in boiler plant, so as to carry out conveying Burning, however such setting not only floor space is big, it is also desirable to two sets of conveying equipments are conveyed, and improve being produced into for boiler This.
The content of the invention:
The purpose of the present invention and provides a kind of boiler two hopper aiming at the deficiency of prior art, solves life Biomass fuel and fire coal can not be placed in same fuel hopper, and floor space is big, it is also desirable to which two sets of conveying equipments are conveyed, and are carried The problem of the production cost of boiler high.
Technology solution of the invention is as follows:
A kind of two hopper of boiler, including boiler body, the side of boiler body are provided with fuel hopper, boiler body By channel connection and the bottom of fuel hopper between, conveyer is additionally provided with passage, fuel hopper is near conveyer Lock material device is provided with position, lock material device includes outer barrel and interior conveying roller, multiple through holes are offered on the barrel of outer barrel, interior Multiple grooves are formed on conveying roller, baffle plate is also formed on outer barrel, baffle plate extends along outer barrel tangential direction, the outward flange of baffle plate Madial wall with fuel hopper is contacted.Fuel hopper can thus be separated by baffle plate, so that realize will be coal-fired and raw Material grainses fuel is positioned in a fuel hopper simultaneously, has greatly saved space, also only needs a set of conveying equipment Conveying is realized, potential safety hazard is not only eliminated, operation has been more convenient, production efficiency is improve, and realize to a certain extent The effect of energy-conservation.
Preferably, the end of one end of outer barrel is extended to outside fuel hopper, and forms cover plate, also formed on cover plate Handle.Outer barrel can thus be rotated by swing handle so that outer barrel drive flapper, realize baffle plate from Fuel hopper side inwall is abutted in, the opposite side inwall reclined to fuel hopper is transferred to, so as to realize fuel hopper storing The change in space, to store different types of fuel.
Preferably, side inwall of the lock material device near fuel hopper, opposite side of the lock material device away from fuel hopper Inwall.So allow for when baffle plate abuts in the lock material close fuel hopper side inwall of device, coal-fired fuel just can be with It is stored in fuel hopper, is transported directly on conveyer not by lock material device;Expect away from lock when baffle plate is abutted in When on the inwall of that side of the fuel hopper of device, biomass fuel can be just stored between fuel hopper and baffle plate, and is led to Cross lock material device and convey biomass fuel to conveyer portionwise, further ensuring will not be mutual between fire coal and biomass fuel Mix and pollute, further eliminate potential safety hazard.
Preferably, the diameter for being smaller than outer barrel between the inwall of the opposite side of lock material device and fuel hopper.This Sample ensures that fritter fire coal can be passed through, and bulk can not it is clean-burning it is coal-fired can be by lock material device card in fuel material In bucket, it is ensured that coal-fired abundant burning.
Preferably, groove has 3~5, the length of groove is identical with the length of interior conveying roller.So allow for groove A certain amount of biomass fuel can be stored, when rotating interior conveying roller, the biomass fuel deposited in groove can be passed through The through hole of outer barrel, on blanking to conveyer, is so achieved that the conveying step by step of biomass fuel, because biomass fuel has Certain strile-bacing property, therefore conveying also ensure that the possibility that biomass fuel is not strile-backd step by step, ensure safety in production Under the premise of ensure that biomass fuel can be fully burned, the energy is effectively make use of, than conventional carrying method energy Conversion ratio improves 15%~20%.
Preferably, through hole has 3~5, the length and width of through hole is consistent with the length of groove and width.So Allowing for being stored in biomass fuel in groove can smoothly blanking.
Preferably, through hole is in Long Circle, and it is distributed on the surface of outer barrel.
Preferably, the roll shaft of interior conveying roller stretches out fuel hopper, roll shaft is also connected with a reducing motor.So allow for In firing biomass fuel, blanking speed and the blanking interval of biomass fuel by the rotating speed of reducing motor, can be adjusted, Reach the optimum utilization of energy.
Preferably, the length of through hole is 5cm~15cm, the width of through hole is 1cm~5cm.So allow for certain big Small biomass fuel could pass through through hole, it is ensured that excessive biomass fuel can be blocked by through hole, be further ensured that biology The abundant burning of matter fuel, it is ensured that energy transformation ratio.
The beneficial effects of the present invention are:
The present invention is separated fuel hopper by baffle plate, so as to realize simultaneously placing coal-fired and biomass granule fuel In in a fuel hopper, space is greatly saved, also only needed a set of conveying equipment to be capable of achieving conveying, not only eliminated peace Full hidden danger, has been more convenient operation, improves production efficiency, and realize the effect of energy-conservation to a certain extent.
