Abstract
The utility model discloses a row's sediment device in biomass gasification stove, including installing the grate in the biomass gasification stove, the pivot of a perpendicular to grate is installed in the central part rotation of grate, and the upper portion of pivot evenly is provided with the grey sword of scraping a plurality of and grate table surface parallel along circumference, and the pivot is passed through transmission and is connected driving motor. The beneficial effects of the utility model are that: passing through transmission by driving motor, to drive the pivot rotatory, and the pivot then drives scrapes grey sword rotation and scrape the ash action, realizes effectively having avoided deposit, the jam of tar with the ash to the cleaning of grate upper portion, has realized the oil recovery of focusing.
Description
Technical field
The utility model relates to solid fuel ignition equipment technical field, the slag discharging device particularly in a kind of biomass gasifying furnace.
Background technology
Gasifying biomass utilizes gasification installation biomass to be burnt under the state of anoxic, makes most of combustiblesubstance be converted into inflammable gas, for generating or cooking after cooling and purifying.According to the difference of combustion system, gasification installation has various ways, the most commonly fixed bed down-draft type gasifying furnace in prior art, it has the features such as structure is simple, cheap, easy operation, be well suited for China's national situation, especially China rural area is applicable in order to process agricultural waste material, such as stalk, rice husk, branch, weeds etc.Bottom it, be all provided with a fire grate in existing vapourizing furnace, fire grate is provided with ash-hole.After vapourizing furnace work, the ash that principle is formed after burning and tar fall through ash-hole, and are collected by dust stratification chamber, but often tar can occur and ash gathers on fire grate, the phenomenon that can not fall.Cause line clogging, can not continuous seepage.
Utility model content
The purpose of this utility model is the shortcoming overcoming prior art, provides the slag discharging device in a kind of biomass gasifying furnace effectively avoiding fire grate top dust stratification.
The purpose of this utility model is achieved through the following technical solutions: the slag discharging device in biomass gasifying furnace, comprise the fire grate be installed in biomass gasifying furnace, fire grate is fixedly installed in the interior furnace chamber of vapourizing furnace, fire grate is provided with ash-hole, the central part of fire grate is rotatably installed with a rotating shaft perpendicular to fire grate, the top of rotating shaft is circumferentially evenly provided with multiple lime scraping knife paralleled with stoker surface, and rotating shaft connects drive-motor by transmission mechanism.
Drive-motor drives rotating shaft to rotate by transmission mechanism, rotating shaft then drives lime scraping knife rotation to carry out scraping grey action, realize the cleaning to fire grate top, tar and the ash-hole of ash through fire grate under the stirring of lime scraping knife fall, and effectively prevent the deposition of tar and ash, blocking.
Preferably, described lime scraping knife a little more than the upper surface of fire grate, thus more effectively can avoid the accumulation of tar and ash on fire grate, and cleaning effect is better.
Preferably, described lime scraping knife is fixedly installed on mount pad, and mount pad is fixedly installed in the upper end of rotating shaft.
Further, described transmission mechanism is the worm screw that the worm gear be fixedly installed in rotating shaft is installed on biomass gasifying furnace with rotation, and worm and wheel is connected with a joggle, and worm screw is connected with the motor shaft of drive-motor.Drive-motor drives worm screw to rotate, and then drives rotating shaft to rotate by worm screw by worm gear.
Preferably, described lime scraping knife is the curved stripe board in cross section.
Further, the rotating speed of rotating shaft is 20r/min ~ 40r/min, and preferably, the rotating speed of rotating shaft is 30r/min.
The utility model has the following advantages:
The utility model drives rotating shaft to rotate by drive-motor by transmission mechanism, and rotating shaft then drives lime scraping knife rotation to carry out scraping grey action, realizes the cleaning to fire grate top, effectively prevent the deposition of tar and ash, blocking, achieve focusing oil recovery.
