Description
Technical field
The present invention relates to the safety control field in cement flour storehouse, particularly a kind of anti-powder storehouse roof fall system.
Technical background
The material transmission in pulvis material powder storehouses (pulvis feed bin) such as cement and fly ash, ground slag powder is that propulsion source is carried with the high pressure air.Fig. 1 is the structural representation of prior art powder storehouse delivery system.As shown in Figure 1, the butt joint bayonet socket is connected extraneous pulvis mass transport passage with powder storekeeper road, and wherein, the other end of transfer passage links to each other with the pulvis material transport vehicle usually.In the middle of Air compressor was driven into gas, material flowed out through pipeline under the effect of gas, can the pulvis material be pressed into the powder storehouse through powder storekeeper road through high pressure air like this.In course of conveying, the silo internal pressure is greater than barometric pressure, and pressurized air outwards discharges through the filter layer of roof scrubber.In case after floating dust blocked the filter core of dust exhaustor, the continuous rising along with the storehouse inner air pressure was easy to cause roof fall accident.
In case emit top event to take place, a large amount of cement or powdered coal ash will leak through top, powder storehouse, not only cause the waste of raw material, also can seriously pollute the environment of mixing plant periphery.The dust exhaustor top cover weighs down down from about 20 meters high-altitude simultaneously, has also brought serious safety misadventure hidden danger; In addition, the dust exhaustor roof fall accident also causes manufacturer to need frequency to change dust exhaustor, also all is that unnecessary cost raises.
For this reason, be badly in need of providing a kind of anti-powder storehouse roof fall system.
Summary of the invention
In view of this, the embodiment of the invention provides a kind of anti-powder storehouse roof fall system, prevents the generation of powder storehouse roof fall accident.
In order to achieve the above object, a kind of anti-powder storehouse roof fall system that the embodiment of the invention provides comprises:
Level detector, control housing and valve constitute; Wherein, it is inner that level detector is installed in the powder storehouse, rises to predetermined material level when detecting material, and detection signal is sent to control housing; Control housing is according to the switch of the detection signal by-pass valve control of level detector transmission; Valve is installed in the middle of butt joint bayonet socket and the pipeline, through controlling said valve switch, controls the beginning of mass transport and stops.
The embodiment of the invention also provides a kind of anti-powder storehouse roof fall system, comprising: level detector, control housing; Wherein, it is inner that level detector is installed in the powder storehouse, rises to predetermined material level when detecting material, and detection signal is sent to control housing; The detection signal that control housing sends according to level detector is controlled the switching of external pneumatic transport equipment power supply.
The anti-powder storehouse roof fall system that utilizes the embodiment of the invention to provide, the pulvis material can get into feed bin as much as possible, and does not exceed capacity; The more important thing is,, need not manual intervention and can force to stop automatically the material operation of putting in storage in case level detector is reported to the police.
Description of drawings
Fig. 1 is the structural representation of prior art powder storehouse delivery system.
Fig. 2 is the structural representation of a kind of anti-powder storehouse roof fall system in the embodiment of the invention.
Fig. 3 is the structural representation of a kind of anti-powder storehouse roof fall system in another embodiment of the present invention.
The specific embodiment
For making the object of the invention, technical scheme and advantage clearer, the present invention is made further detailed description below in conjunction with accompanying drawing.
Shown in Figure 2 is the structural representation of a kind of anti-powder storehouse roof fall system in the embodiment of the invention.As shown in Figure 2, this system comprises a level detector, control housing, and annunciator and valve constitute.It is inner that level detector is installed to the powder storehouse, is used to detect material and whether rises to predetermined material level.This level detector sends to control housing through wired or wireless mode with detection signal.Detection signal control annunciator and valve that control housing sends according to level detector.Valve is according in the middle of butt joint bayonet socket and pipeline, through controlling this valve switch, can control the beginning of mass transport and stops.
Before the beginning convey materials, operating personal at first is fixed to the butt joint bayonet socket with the delivery duct in material source, opens valve, and material gets in the feed bin through pipeline under the effect of suppressing of Air compressor.After level detector is sensed material and risen to predetermined material level, transmit signal through circuit and give control housing.Control housing receives after the signal, sends alarm message through circuit and gives annunciator, and annunciator is implemented to report to the police; And after predetermined time-delay, the instruction that control housing sends Locking valve through circuit is stopped unnecessary material outside valve, realizes controlling the purpose of the inventory of putting in storage.
The system that utilizes the embodiment of the invention to provide, the pulvis material can get into feed bin as much as possible, and does not exceed capacity; In case level detector is reported to the police, need not manual intervention and can force to stop the material operation of putting in storage.
Fig. 3 is the structural representation of a kind of anti-powder storehouse roof fall system in another embodiment of the present invention.As shown in Figure 3, its system substantially constitutes same Fig. 2, and difference only is that the output information of control housing is not the switching of by-pass valve control, but is used to control the power supply of external pneumatic transport equipment (such as, Air compressor); After annunciator was implemented to report to the police, after predetermined time-delay, control housing broke off the power supply of external pneumatic transport equipment through circuit control like this; Pressure stops operation; Do not having the effect of high pressure air, material also promptly stops to get into the powder storehouse, thereby realizes controlling the purpose of the inventory of putting in storage.
It will be understood by those skilled in the art that the disclosed anti-powder of embodiment of the invention storehouse roof fall system both can use on like chemical powder materials such as cement, fly ash, also can be used on the food pulvis materials such as flour, or on other any pulvis materials.
The above is merely preferred embodiment of the present invention, and is in order to restriction the present invention, not all within spirit of the present invention and principle, any modification of being done, is equal to replacement etc., all should be included within protection scope of the present invention.
