Description
Technical Field
The invention belongs to the technical field of waste incineration, and particularly relates to a hydraulic quantitative feeder of an urban domestic waste incinerator.
Background
The garbage is a product of human life, and the urban household garbage is gradually increased year by year along with the continuous improvement of the material consumption level of people, and becomes a main component of the waste. Garbage power generation is a technology for generating power by converting chemical energy of garbage into heat energy after the garbage is collected and classified. Namely, the garbage with higher combustion value is incinerated at high temperature, pathogenic organisms and corrosive organic matters can be thoroughly eliminated in the high-temperature incineration process, and simultaneously, heat energy is generated and converted into high-temperature steam, and then work is performed to generate electricity.
The whole combustion system of the garbage incinerator comprises processes of garbage input, combustion (drying, combustion and burnout), slag discharge, complete combustion of combustion gas and the like. Firstly, the garbage is transported to an incineration plant by a transport vehicle, weighed by a weighbridge and finally transported to a garbage pit for standby application, leachate in the pit is firstly considered to be sprayed into the incinerator for incineration, if the amount of the leachate is too much and can not be sprayed into the incinerator completely, the leachate is considered to be sent into a sewage treatment plant for treatment, after the garbage is stored in the pit for 5 days, the garbage is grabbed by a garbage crane and sent into a charging hopper, the size of an inlet of a feeding material is controlled by a movable baffle, and the garbage is stably and continuously sent into the incinerator by a feeding machine.
The existing feeder mostly adopts a conveyor belt to convey garbage into a combustion furnace, and the conveyor belt type feeding device has enough rigidity to support materials so as to ensure that the deformation generated on carrier rollers with effective intervals is as small as possible, which is very necessary for ensuring the smooth movement of the conveyor belt and the materials on the carrier rollers, and certain rigidity can also ensure that the conveyor belt and the materials generate small bending deformation in the transverse direction; the load-bearing capacity decreases with increasing conveyor belt width and material weight, and for wider conveyors stronger load-bearing materials are required, as the load increases and the belt width increases with equal effect, and for heavier materials stronger belt cores are required, as the load increases. The conveying belt still has the off tracking problem to and wearing and tearing, fish tail, damage, overlap joint position fracture scheduling problem, the damage of conveying belt has not only been accelerated to the appearance of these equipment problems, causes revealing of rubbish easily moreover.
Disclosure of Invention
The invention provides a hydraulic quantitative feeder of an urban domestic garbage incinerator, aiming at effectively solving the problems in the background technology, and the specific technical scheme is as follows:
