Description
Technical field
The utility model relates to the powder feedway, is specially the powder feedway with autonomous cruise speed system that uses in a kind of mixing plant field.
Background technology
In the engineering construction process, most of cement concretes are centralized mixing in cement concrete mixes mixing plant all, this helps improving concrete production level, but powder leakage meeting caused bigger influence to environment when the powder transport trolley was filler bin conveying powder in the mixing plant field, and this and the current trend of advocating green construction deviate from.The leakage of powder is simultaneously polluted, and also is fatal source of pollution to the worker at the production line who is in the camp site for a long time.The major cause that causes powder to reveal is that the powder conveying is excessive, causes filler bin internal pressure height to cause dust exhaustor to lose efficacy.The powder of present employed mixing plant is carried, and all is that the high output diesel engine that relies on the powder car to provide for oneself drives Air compressor work.We observe the delivery system that the powder car provides for oneself following problem: 1, to provide delivery system operation labour intensity for oneself big for the powder car, need personnel on duty in the powder conveying when putting in storage, manual control is prone to error when filler bin is bought securities with all one's capital, be easy to cause the dust of filler bin to reveal, the gross pollution surrounding environment, when serious, because the too high dust exhaustor that makes of filler bin internal pressure breaks away from filler bin, the production safety accident takes place; 2, to carry the diesel motor noise big for the powder car, especially carries powder night, has a strong impact on surrounding resident living environment; 3, under fuel price constantly rose background at present, the delivery system powder that the powder car is provided for oneself was carried the cost height.
Summary of the invention
The utility model exists in order to solve existing powder feedway that dust easily leaks, labour intensity height and the high problem of cost, and a kind of powder feedway with autonomous cruise speed system is provided.
The utility model is to adopt following technical scheme to realize: the powder feedway with autonomous cruise speed system, comprise the powder car that has fluid bed interface and discharging opening, be provided with the filler bin of feeding tube in it, be provided with the discharge nozzle that is communicated with both between the lower end of feeding tube and the discharging opening, also comprise control housing, Air compressor, the filler bin upper portion side wall is fixed with level-sensing device, between level-sensing device and the control housing, be connected between control housing and the Air compressor, the outlet of Air compressor is provided with the airline that communicates with it, one end of airline is provided with electric T-shaped valve, electric T-shaped valve in addition two mouthfuls be respectively equipped with an airduct that is communicated with the fluid bed interface and the secondary air channel that is communicated with the feeding tube lower end.In whole powder transportation work process, start Air compressor, when pressure reaches setting value, transfer to control housing according to the level-sensing device signal, and then automatically Air compressor is realized different operating mode Electromechanical Control, the powder in the powder car in discharge nozzle is sent filler bin to, has been reduced personnel operation intensity; When the level-sensing device signal aspect and indication was bought securities with all one's capital, the level-sensing device signal transferred to control housing, and control electric three passes ball valve switches to secondary air channel, and pressurized air drains the surplus ash in the delivery pipe, and auto-stop is eliminated feeding tube plugging phenomenon.
Also be provided with electro connecting pressure gauge, safety valve and electric-powered air release valve on the airline, when filler bin dust exhaustor clogging of filter element causes the filler bin hypertonia, the electro connecting pressure gauge signal transfers to through control housing control air compressor motor and shuts down and electric-powered air release valve is opened, prevent because the too high dust exhaustor that makes of filler bin internal pressure breaks away from filler bin, the production safety accident takes place, when a little higher than setting value of airline internal pressure, can carry out exhaust simultaneously by safety valve.
Be equipped with check valve and ball valve on airduct and the secondary air channel, check valve is used to prevent the backflow of air on airduct and the secondary air channel, and ball valve can be used for the pipeline of airduct and secondary air channel is cut off when maintenance detects, and structure design is more rationally reliable.
The utlity model has following beneficial effect: 1, dust pollution obviously reduces, and when adopting powder to carry autonomous cruise speed system to carry powder, can prevent from effectively to continue to carry powder and dust exhaustor to break away from filler bin when the filler bin dust exhaustor lost efficacy; 2, noise obviously reduces, and prior art carries the work of diesel-engined drive air pump by the powder car, and noise reaches 114 decibels, and up-to-date technology itself is by the direct motor drive air pump, and self noise reduces by 70 decibels, adds sound arrester simultaneously outside air pump, and noise is just lower; 3, effect improves more than 30%, and when adopting the powder transport trolley to be filler bin conveying powder, hundred side's powder time of deliveries are 140 minutes, and when employing carried autonomous cruise speed system to carry powder with powder, hundred side's powder time of deliveries were 100 minutes; 4, powder carries 136.55 yuan of delivery system hundred side's fuel oil consumptions, and this uses novel hundred sides to consume 52.77 yuan of the electricity charge, and economic benefit is saved more than 60% than prior art; 5, safety is controlled more in course of conveying for the utility model; 6, reduce personnel's labour intensity.
