Abstract
The present invention discloses a mechanical boiler bed material adding system, including a bed material storage residue bin, a vibration sieve and scraper conveyors, the vibration sieve and the scraper conveyors are sequentially arranged below the residue bin, a hoisting machine is arranged on one side of the scraper conveyers, and a bed material sequentially passes through the residue bin, the vibration sieve and a ground scraper conveyor to reach into the lower end part of the hoisting machine, and is conveyed a boiler-front scraper conveyor by a feeding machine. The mechanical boiler bed material adding system avoids the backflow, precipitation or floating of the bed material in the conveying process, the human operation phenomenon can be avoided by the mechanical conveying method, and the mechanical boiler bed material adding system saves the manpower, reduces the energy consumption, and improves the efficiency.
Description
Technical field
The present invention relates to a kind of boiler bed material add-on system, be specifically related to a kind of mechanical type boiler bed material add-on system.
Background technology
Bed material is also bed material, is fluidized-bed combustion boiler necessary medium when starting.The slag of discharge after general more commonly fluidized-bed combustion boiler burns down or river sand, bed material is placed in inside burner hearth, necessary process before being coal supply, in the loss of throwing coal and lime stone external crucible material when providing the initial bed material of boiler after initial start-up and overhaul and boiler startup, keep certain bed pressure, it is the necessary process of circulating combustion, bed material will be transported to burner hearth by conveying mechanism in slag storehouse, because conveying mechanism is generally placed on ground, and the burner hearth of boiler is liftoff has certain altitude, the particle diameter and the proportion that add material of going to bed are larger, therefore, bed material can sink because of the effect of gravity in course of conveying from the bottom to top, precipitation or floating, can not effectively be delivered in burner hearth, efficiency is lower.
Summary of the invention
For solving the problems of the technologies described above, the invention provides a kind of mechanical type boiler bed material add-on system, can high efficiencyly be that burner hearth adds bed material, simplifying operating process, reduce cost of labor, also reduce energy consumption simultaneously.
For achieving the above object, technical scheme of the present invention is as follows:
A kind of mechanical type boiler bed material add-on system, comprise the slag storehouse of storage bed material and the vibratory sieve be located at successively below slag storehouse and ground scratch board conveyor, scratch board conveyor side, described ground is provided with an elevator, bed material in the bottom arriving described elevator successively after slag storehouse, vibratory sieve and ground scratch board conveyor after be delivered to stokehold scratch board conveyor through a batcher.
Preferably, be provided with service valve below described slag storehouse successively, inlet valve and is communicated with being flexible coupling of described vibratory sieve.
Preferably, described scratch board conveyor is placed on ground and stokehold respectively.
Preferably, described elevator upper end is communicated with a conveying pipeline, and bed material is delivered to described batcher through this conveying pipeline.
Pass through technique scheme, mechanical type boiler bed material add-on system provided by the present invention avoids bed material in the refluence of course of conveying, precipitation or floating, mechanical mode of movement it also avoid the phenomenon in the past needing manual operation, not only save artificial, reduce energy consumption and improve efficiency.
