Abstract
The utility model relates to an indirect ash-discharging device for pyrite, zinc ores, gold sand-based sulfuric acid plants, which includes a spiral conveying device. The device consists of a shell, a rotating shaft and a helical vane, and a plurality of feed inlets are opened in the upper part of the shell, an upper feed inlet is opened upward in the rear end of the shell corresponding to the tail end of the helical vane, an feed funnel is sealedly connected with the shell in the position corresponding to the feed inlet, with a funnel feed downpipe at the bottom of the feed funnel, and two baffles are connected upward with the shell along the length direction of the shell corresponding to the upper feed inlet. Owe to the structural features, the calx naturally forms a media which seals the inlet and the outlet, so the model has good air locking property. The utility model has a big cavum and good anti-blocking property, so the volume of maintenance is greatly reduced. Because a principal spindle adopts a hollow structure with the cooling water passing through, and a main bearing adopts the wear resistant cast iron alloy bearing shell, so the application life in high temperature, the wear resistance and the decay resistance of the utility model are greatly improved.
Description
Technical field
The utility model relates to the ash discharge equipment of the ash exhauster, particularly a kind of non-straight-line of a kind of troilite, zinc ore, gold sand acid making system.
Background technology
Contained calx (the little slag of particulate) in the high-temperature furnace gas (about 900 ℃) that the fluidizing reactor of troilite, zinc ore, the relieving haperacidity of gold sand comes out, 99% is removed behind waste heat boiler, cyclone dust collectors, electric cleaner.And the calx of removing generally adopts star ash-valve, conveying worm to deliver in the slag ash handling plant.
Existing these equipment generally exist air locking poor (because equipment such as waste heat boiler, deduster in the system are in-move under the negative pressure of 200mm, the air locking of ash discharge equipment can will directly influence the normal operation of system), easily obstructions, heat-resisting quantity poor (calx of discharge is all about 450 ℃), corrosion-resistant (because residual sulphur in the calx and water, steam formation acid medium etching apparatus).
Summary of the invention
The purpose of this utility model is exactly in order to address the above problem, and provides a kind of air locking good, is difficult for stopping up, and can significantly reduce the helical feed high temperature air locking machine of maintenance capacity.
Technical solution of the present utility model:
A kind of helical feed high temperature air locking machine, it includes screw conveyor, this equipment is made of housing, rotating shaft, helical blade, housing top has a plurality of charging apertures, the tail end position that it is characterized in that the corresponding helical blade at the housing rear portion upwards has the top discharge mouth, be connected with out funnel to should the discharging opening position sealing close wearing on housing, the discharging funnel bottom is provided with the funnel feed opening, upwards is connected with two baffle plates in the position of the corresponding top discharge mouth of housing along shell length direction both sides.
The utility model is to be used for the occasion that ash inlet and dust inlet have certain distance (maximum can reach about 6m), and its shell structure is a circular cylinder body (seamless steel pipe), in the rotating shaft of stainless steel helical blade is arranged, hollow structure is taked in rotating shaft, interior logical cooling water.Bearings at both ends adopts alloy wear-resisting cast iron bearing shell.Because the structure of ash hole, the calx ash discharge overflows to the bottom ash hole from housing top, like this, when calx is transferred, thereby makes import and export obtain sealing because the overflow of calx is discharged.In order to check the ash discharge situation at any time, a sand seal inspection socket is arranged above ash hole.In addition, stop up the bearing of ash discharge side, on the main shaft of ash discharge side, a reverse acting spiral blade (about pitch is long) is arranged in order to prevent calx.The utility model is because structural characteristics make calx form the medium of airtight import and export naturally, thereby air locking are good.The utility model cavity is big, is difficult for stopping up, thereby has significantly reduced maintenance capacity.The utility model is because hollow structure is adopted in rotating shaft, interior logical cooling water, and bearing adopts alloy wear-resisting cast iron bearing shell, thereby long service life at high temperature.And because of the material of rotating part has adopted the 18-8 stainless steel, its rotproofness and wearability all are improved greatly.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is that the A-A direction of Fig. 1 is partly cutd open structural representation.
The specific embodiment
As Fig. 1,2, the utility model includes screw conveyor, this equipment is made of housing 1, rotating shaft 2, helical blade 3, housing 1 top has a plurality of charging apertures 4, characteristics of the present utility model are, the tail end position of corresponding helical blade 3 upwards has top discharge mouth 5 at housing 1 rear portion, be connected with out funnel 6 to should discharging opening 5 positions on housing 1, sealing close wearing, go out funnel 6 bottoms and be provided with funnel feed opening 7, upwards be connected with two baffle plates 8 along housing 1 length direction both sides in the position of the corresponding top discharge mouth 5 of housing 1.
In the utility model, the height of described baffle plate 8 is slightly larger than the diameter of housing 1, make in the housing 1 the calx that is transferred thereon discharging opening 5 overflow from two side shields 8 and enter out funnel 6, send from the funnel feed opening 7 that goes out funnel 6 again, play the effect of good lock gas.Be provided with movable sealing lid 9 in the upper end that goes out funnel 6, when seal cover 9 is opened, can check the discharging situation of the top discharge mouth 5 of screw conveyor,, also can clear up easily if any obstruction.The rotating shaft 2 of the utility model screw conveyor can be hollow shaft, with logical cooling water.
