Description
Technical field
It the utility model is related to field of garbage disposal equipment, more particularly to a kind of sludge front-furnace feeding machine.
Background technology
Sludge incineration power generating stove is when in use, it is necessary to which batcher is constantly fed, however, currently used batcher
During for sludge incineration power generating stove, poor-performing, following defect is primarily present：1st, the fire door temperature of sludge incineration power generating stove
Very high, the fire door of high temperature can pass to heat on batcher, batcher can be caused to deform, and then influence the normal fortune of batcher
OK, some potential safety hazards are brought or even；2nd, the bearing on batcher is because long-time is at higher temperature, common axle
Hold that type of cooling effect is poor, the service life of bearing can be greatly shortened；3rd, the pipe axial length time of batcher screw rod be in compared with
At high temperature, the air in pipe axle, which can expand, in turn results in pipe shaft distortion；4th, the poor fluidity of sludge, not enough enrich, burn
When flue gas can run helter-skelter；5th, sludge has certain corrosivity, and the screw rod of batcher, can be rotten after long-time use
Erosion.
Utility model content
In view of the above-mentioned problems, the utility model provides a kind of sludge front-furnace feeding machine, sludge incineration hair is effectively reduced

The corrosion resistance of screw rod, so as to solve the problems, such as to be pointed out in background technology.
The technical solution adopted in the utility model is：
A kind of sludge front-furnace feeding machine, including casing, and the screw rod being arranged in casing, described screw rod pass through
Bearing is arranged on casing with bearing block, and described screw rod is driven by reducing motor, and charging is offered on described casing
Mouth and discharging opening, described casing are coated with one layer of thermal insulation layer on the outside of discharging opening.
Preferably, described thermal insulation layer is made up of ceramic fiber blanket.
Preferably, bearing pipeline lubricating arrangement is provided with described casing.
Preferably, passage is offered on the pipe axle of the screw rod, one end of the passage and the inside of pipe axle
Hollow area connects, and the other end connects with outside air.
Preferably, the cylindrical upper heap of the blade of the screw rod is welded with a wearing layer.
Preferably, described wearing layer is wearing layer thick 3mm made of Si Taili wear resistant alloy materials.
Preferably, the pipe axle and blade of the screw rod are made of heat-resistance stainless steel material.
Preferably, sealed between the pipe axle and casing of the screw rod by stuffing seal.
The beneficial effects of the utility model are as follows：
1st, effective isolation has been obtained by the heat-insulated of ceramic fiber blanket, the heat of sludge incineration power generating stove fire door, significantly
Reduce the heat that batcher is passed to from sludge incineration power generating stove, effectively prevent the deformation of batcher；
2nd, the bearing in bearing block is timed quantitative auto-supply by bearing block pipeline lubricating arrangement, so as to significantly
Cooling effect is improved, prevents the temperature too high life-span for influenceing bearing；
3rd, after the air heats expansion of passage hollow area in pipe axle, can be discharged by passage, so as to prevent
Air expansion causes pipe shaft distortion in pipe axle；
4th, the screw rod of batcher is made of heat-resisting, corrosion resistant stainless steel material, substantially increases the resistance to of screw rod
Corrosive nature, extend service life.
