Abstract
An electric flap valve for pneumatic ash conveying comprises a machine transmission mechanism, a round shell, a front end cover, a rear end cover, a main shaft, impellers, a feeding inlet and a discharging outlet. The electric flap valve for pneumatic ash conveying is characterized in that radial through holes are formed in the wall of the round shell located on the oblique upper portion of annular spaces of axial gaps between the front end cover and rotating faces on the two sides of the impeller buckets and between the rear end cover and the rotating faces on the two sides of the impeller buckets respectively, an inclined air inlet pipe is fixed on each radial through hole, an electromagnetic valve is fixed on the other port of each inclined air inlet pipe, and air inlets of the electromagnetic valves are communicated with a compressed air source pipe through pipelines. The electric flap valve has the advantages that the electromagnetic valves are used for blowing air to the axial gaps between the front end cover and the rotating faces of the impellers and between the rear end cover and the rotating faces of the impellers, and blocking and abrasion can not happen in the spaces.
Description
Technical field:
The utility model relates to ash conveying device, particularly a kind of Pneumatic ash conveying electric lock pneumatic device.
Background technology:
As the coal chemical industry enterprises of utilizing carbonated coal balls synthetic ammonia, Pneumatic ash conveying is the clean principal mode of carrying of ash, and electric lock pneumatic device is also desirable auxiliary equipment conventional in conveying, discharging, feed proportioning system
Electric lock pneumatic device (rigidity revolving plow reclaimer, star-like discharging device) is comprised of motor transmission mechanism, round casing, front and rear cover, main shaft, impeller, inlet point, discharge port.Impeller is bucket-shaped impeller, eight impeller unifications towards and be fixed on main shaft, the powder grain material that top disconnector (or hopper) falls just enters impeller lattice chamber by inlet point, and along with the rotation of bucket-shaped impeller, be reversed and deliver to discharge port and discharge, in whole working process, can continuous and quantitative feed and discharging.Being applicable to the industries such as power plant, cement mill, chemical plant carries in feed proportioning system, during as conveying dry powdery material, lock gas or dosing use, also the ash bucket lower ash output that can be used for dust exhaustor and Air preheater, it is simple in structure, stable performance, operating maintenance is convenient, is auxiliary equipment desirable in conveying, discharging, feed proportioning system.
Electric lock pneumatic device is installed has directivity, and common structure is: round casing and vane rotary periphery upper gap are less, to reduce ash, falls into outside impeller bucket; Round casing and vane rotary cylindrical underclearance are larger, make discharging smooth and easy; The endplay of front and rear cover and both sides, impeller bucket limit plane of revolution is equally also up-small and down-big, be also for top backgauge, below discharging smooth and easy.
As carrying the powder ash that carbonated coal balls is raw material, in order to reduce handling process, produce airborne dust, conventionally on the twin shaft humidifier after the discharging of electric lock pneumatic device, can water distribution stir, the aqueous vapor on humidifier, water smoke can rise, and make the axial both sides of electric lock pneumatic device front and rear cover very easily tie full lump.If not regular, open and inspect removing, gently acceleration equipment wearing and tearing, heavy cause the damage of impeller device.
Summary of the invention:
The purpose of this utility model is to overcome above-mentioned defect, and a kind of Pneumatic ash conveying electric lock pneumatic device is provided.
Scheme of the present utility model is: comprise machine transmission device, round casing, front end cover, rear side housing, main shaft, impeller, inlet point, discharge port, it is characterized in that: on the shell wall of the oblique upper round casing of the endplay annular space of front end cover, rear side housing and both sides, impeller bucket limit plane of revolution, offer respectively a radial direction through hole, on radial direction through hole, fix an oblique air inlet pipe, an electromagnetic valve is fixed in oblique air inlet pipe another port, and electromagnetic valve admission port is communicated with compressed air gas source pipe by pipeline.
The utility model has the advantage of: electromagnetic valve batch (-type) is blown to two side clearances to front and rear cover and vane rotary over glaze, make this space can not produce caking and wearing and tearing.
Accompanying drawing explanation:
Fig. 1 is electric lock pneumatic device working environment schematic diagram.
Fig. 2 is the utility model structural representation.
Fig. 3 is the A-A cutaway view of Fig. 2.
The specific embodiment:
The utility model comprises machine transmission device, round casing 5, front end cover 8, rear side housing 9, main shaft 3, impeller 4, inlet point 1, discharge port 6, it is characterized in that: on the shell wall of front end cover 8, rear side housing 9 and the oblique upper round casing 5 of the endplay annular space of impeller 4 bucket both sides, limit plane of revolutions, offer respectively a radial direction through hole, on radial direction through hole, fix an oblique air inlet pipe 2, an electromagnetic valve 7 is fixed in oblique air inlet pipe 2 another port, and electromagnetic valve 7 admission ports are communicated with compressed air gas source pipe by pipeline.
In normal course of operation, by electromagnetic valve batch (-type), automatically control pressure gas and carry out batch (-type) purging.The shell wall of front and rear cover, round casing can not produce caking and wearing and tearing.
