According to the air purging device, the surface of the conveying belt, which have special cleaning requirements, is cleaned by compressed air; the air purging device has a good cleaning effects for various sideway conveying belts and blast-furnace main feeding conveyors in the metallurgical industry; and the device is particularly suitable for cleaning conveying belts which convey powdery materials with small granularities. The air purging device is low in cost and facilitates environmental protection.
Description
Technical field
The present invention relates to a kind of belt conveyer parts, particularly a kind of air purge set.
Background technology
At present, the cleaning of two-stage polyphosphazene polymer ammoniacum swabbing pig is generally adopted in the cleaning of belt in belt conveyor face, but because the impact of the factors such as characteristic (such as the shirt rim load-transfer device) of the material characteristic of some occasion and antarafacial load-transfer device, cause conventional two-stage polyphosphazene polymer ammoniacum swabbing pig cleaning thoroughly maybe can not clean load-transfer device etc., and pollution working environment, for solving the difficult problem in these course of conveying, research and develop a kind of air purge set aobvious still for important.
Summary of the invention
Technical matters to be solved by this invention is in order to overcome above-mentioned weak point, to provide a kind of air purge set to solve the cleaning difficult problem in the said process.
A kind of air purge set is installed in the below of load-transfer device, comprising:
One blowpipe that is connected with pressurized air, described blowpipe are installed in by pipe bracket on the frame of belt conveyer,
Be serially connected in first, second shutoff valve and two electric change valves on the blowpipe, wherein two electric change valves are between first, second shutoff valve;
Be connected in the first gas ejector pipe on the described blowpipe and be connected in the second gas ejector pipe on the described blowpipe by elbow by threeway, wherein the first gas ejector pipe and the second gas ejector pipe are installed in by lance holder on the frame of belt conveyer, are provided with pipe cap at the end of the first gas ejector pipe and the second gas ejector pipe;
The interval is installed in some the first nozzles on described the first gas ejector pipe and interval and is installed in some second nozzles on described the second gas ejector pipe, the wherein axis of the first nozzle and second nozzle and Belt Conveying direction angle at 45 °.
In a preferred embodiment of the invention, the injection segment angle of described the first nozzle and second nozzle is 45 °.
In a preferred embodiment of the invention, also cross-over connection has a compressed air delivery arm at the two ends of described first, second shutoff valve, is serially connected with one the 3rd shutoff valve on the described compressed air delivery arm.
Owing to adopted technique scheme, compression of the present invention is empty by being sprayed on one air knife of formation on the load-transfer device driving surface through nozzle after shutoff valve and the two electric change valves adjusting blast, can clean with sticking to the tiny viscous material of carrying on the zone face, because the characteristic of air can also be cleaned antarafacial load-transfer device (such as the shirt rim load-transfer device).
The present invention is owing to adopt above structural development; can carry out the multi-staged air cleaning; avoided the scrape along of directly scraping of load-transfer device to tear; improved the service life of adhesive tape; be particularly suitable for that the high spud angle shirt rim is carried, the conveying of powdery viscous material, and the cleaning work of iron industry blast furnace main belt machine; be beneficial to the cleaning of Protection environment, have wide range of applications.
