Abstract
The utility model relates to an air-cannon material backflow prevention device comprising an air cannon body, an air-intake pipeline arranged at one end of an air cannon, a quick exhaust pipeline, a spraying outlet arranged on the opposite direction of the exhaust pipeline and a spraying pipe connected with the spraying outlet through a flange. A non-return cover plate is arranged inside the spraying pipe. By the air-cannon material backflow prevention device, material backflow is effectively prevented, number of times of cleaning the air cannon is reduced, service life of the air cannon is prolonged, and cost is low; therefore, the air-cannon material backflow prevention device has good economic and social benefits.
Description
Technical field
The utility model relates to air bubble technical field, is specifically related to the anti-material recycling device of a kind of air bubble.
Background technology
Air bubble (Air cannon) (another name: air flow-aid device, Arch-Breaking Device, Cleaning device for pipeline) be the special purpose device of the phenomenons such as the material arch camber that prevents and eliminate all kinds feed bin, hopper, tube furcation place, feed bin blocking, sticky wall, delay, be applicable to cartridge type feed bin, hopper, pipeline and flat windrow that various steels, cement concrete and other material are made.Having wide range of applications of air bubble, all has and relates in many industries.
Air bubble principle of work for storing the high pressure gas of certain volume in tank body, during use, open fast drain tap, utilize the impulsive force of the high velocity air generation of moment ejection, overcome static friction and the plugging fault of material, make the granule materials in container or pipeline recover to flow unimpeded.But because injection pipe is arranged in equipment pipe or instrument, easily in air pressure shakiness or when predicting, granule materials is back in air bubble, has a strong impact on service life and the work efficiency of air bubble.
Given this, need to invent the anti-material recycling device of a kind of air bubble, to ensure air bubble normal operation, extend the service life of air bubble.
Summary of the invention
Problem to be solved in the utility model is to provide a kind of air bubble anti-material recycling device, and it can prevent feed back, ensures air bubble normal operation, extends the service life of air bubble, reduces the cleaning time of air bubble.
For addressing the above problem, technical solution adopted in the utility model is as follows:
The anti-material recycling device of a kind of air bubble, it comprises air bubble body, be arranged at induction tract, the Quick air-discharge pipeline of air bubble one end and be arranged at the rightabout jet exit of described gas exhaust duct, and the jet pipe being connected with described jet exit by flange, described jet pipe inside is provided with check cover plate.
As the utility model, further improve, described check cover plate, by automatically controlling, is synchronizeed and is opened or closed with described Quick air-discharge pipeline.
Compared with prior art, the beneficial effects of the utility model are as follows:
Owing to being provided with check cover plate in the jet pipe of the utility model place, therefore at air bubble readiness for action, check cover plate can block jet pipe, avoids feed back.When air bubble is worked, check cover plate is washed open by the intrinsic high pressure gas of air bubble, spouting, finishes the work.The utility model actv. has prevented the backflow of material, has reduced the clearing times of air bubble, has extended the service life of air bubble, and with low cost, possesses good economic benefit and social benefit.
Preferably, the check cover plate in the utility model can be by controlling automatically, and the execution of synchronizeing with Quick air-discharge pipe opens or closes order, has effectively improved the intellectuality of check cover plate.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is A partial enlarged drawing of the present utility model.
In the accompanying drawings: 1 air bubble body, 2 induction tracts, 3 Quick air-discharge pipelines, 4 jet exits, 5 jet pipes, 6 check cover plates.
The specific embodiment
Below in conjunction with attached Fig. 1 and 2, by specific embodiment, the utility model is described in further detail.
As shown in attached Fig. 1 and 2, the anti-material recycling device of a kind of air bubble, it comprises air bubble body 1, be arranged at induction tract 2, the Quick air-discharge pipeline 3 of air bubble one end and be arranged at the rightabout jet exit 4 of described gas exhaust duct 3, and the jet pipe 5 being connected with described jet exit 4 by flange, described jet pipe 5 inside are provided with check cover plate 6.
Certainly, as optimizing check cover plate 6 of the present utility model, can, by automatically controlling, synchronize and open or close with described Quick air-discharge pipeline 3.
Above embodiment is only unrestricted in order to the technical solution of the utility model to be described, although the utility model is had been described in detail with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can modify or be equal to replacement the technical solution of the utility model, and not departing from the spirit and scope of technical solutions of the utility model, it all should be encompassed in the middle of claim scope of the present utility model.
