Existing thermal power plant tradition chute blockage detection device is mounted in threeway coal conduit pipeline, to a certain extent may be used
To play the role of chute blockage protection.But hanging coal due to chute blockage switch probe or coal conduit side wall causes to switch frequent movement, malfunction
Rate is very high, and because chute blockage switch is smashed in the sundries such as coarse coal or stone whereabouts, switching damage rate is also very high.
Utility model content
Technical problem to be solved in the utility model is just to provide a kind of thermal power plant coal conduit chute blockage detection dress
It sets, both can effectively solve defeated coal coal conduit chute blockage card coal and viscous coal phenomenon, and detect the chute blockage that malfunction rate is low, switching damage rate is low
Detection device.
Above-mentioned technical problem is solved, using following technical scheme:
A kind of thermal power plant coal conduit chute blockage detection device, characterized by comprising:
One is set to the chute blockage sensing chamber on the outside of coal conduit barrel, is a container, is provided with opening on one side, open face is by falling
The corresponding aperture being provided on coal cylinder barrel is connect with coal conduit;The center of top of chute blockage sensing chamber is provided with through-hole;
Chute blockage detection switch is set at the top of the chute blockage sensing chamber above through-hole, and sensing chamber is fixedly connected with chute blockage,
Including shell and triggering sensing device, the triggering sensing device is located in shell, and contact portion passes through at the top of chute blockage sensing chamber
It is indoor that through-hole enters chute blockage detection.
The chute blockage sensing chamber is hexahedron box, and the open face that bottom surface is contacted with coal conduit barrel, which is tilted down, to be set
Meter.It can prevent chute blockage from detecting indoor accumulation coal cinder in this way, the coal cinder being splashed into once in a while is because bottom is related to falling off quickly in inclined-plane
It goes out, false protection will not be generated.
Further, the bottom surface of the chute blockage sensing chamber and open face are at 45 degree of angles.
The through-hole is circular through hole.
The opposite face of chute blockage sensing chamber open face is dismountable cover board.When chute blockage occurs, coal stream pours in chute blockage
Sensing chamber removes cover board, can be convenient cleaning coal cinder.
The chute blockage detection switch is bolted with chute blockage sensing chamber, and nut has elastic component and conventional pads, prevents
Bolt looseness caused by vibrating.
Further, the elastic component is spring shim, and conventional pads are flange.
The triggering sensing device includes motor, and it is another to be fixed on the shaft for the shaft that one end is connect with the motor
The blade at end, the motor are rotated by shaft band movable vane piece.When product coal, which enters sensing chamber's inner barrier blade, to be rotated, block up
Coal switch issues chute blockage signal.
The utility model has the following beneficial effects:
(1) the chute blockage detection device of the utility model is placed outside on the outside of coal conduit barrel, there is independent chute blockage sensing chamber, with
Coal breakage room connection, it can play the role of chute blockage protection, malfunction rate can also be reduced, coal cinder is avoided to make detection switch shock
At damage, reduce switching damage rate;
(2) the utility model chute blockage detection device bottom angled designs, and when normal operation, not will cause coal cinder in sensing chamber
Interior accumulation generates false protection;When chute blockage occurs, coal stream pours in chute blockage sensing chamber, and chute blockage switch detects material and timely
Alarm;It is equipped with dismountable cover board simultaneously, facilitates the cleaning after chute blockage to coal cinder in detection device.
(3) the utility model chute blockage structure of the detecting device is simple, easily implements, small investment.
