A kind of feed arrangement and the powder material tank using the feed arrangement
Technical field
The utility model is related to a kind of feed arrangement and the powder material tank using the feed arrangement.
Background technology
At present, most powder material tank top is equipped with roof scrubber, and its main purpose is to collect dust, prevents powder
Dirt discharges atmosphere pollution.The material transferring of cement and flyash powder cabin is conveyed by power source of pressure-air, normal to grasp
Then work order starts roof scrubber, most for first sending delivery hose to be connected fastening with the feed pipe of powder material tank vehicle-mounted wind
After start wind and send operation, in course of conveying, the pressure in powder material tank is more than atmospheric pressure, compressed air by roof scrubber to
Outer release.Due to automaticity it is not high, it is cumbersome, and the quality of operating personnel is very different, causes roof scrubber
Forget to open or open not in time, cause the pressure inside powder material tank constantly to raise, it is easy to cause roof fall accident, remove silo roof
Dirt device is damaged.Cement or flyash in powder material tank is blown upper high-altitude by compressed air, forms big pollution sources, severe contamination
Around environment, What is more, and roof scrubber top cover is rushed to compressed air tens meters of high-altitude, cause serious safety
Accident.

Specific embodiment
Below in conjunction with the accompanying drawings embodiment of the present utility model is described further.A kind of powder material tank of the present utility model
Specific embodiment, as shown in Figure 1 to Figure 2, powder material tank includes powder tank, the feed arrangement being arranged on powder tank
And deduster, deduster is roof scrubber, and feed arrangement includes feed pipe 1 and the block piece being movably set on feed pipe 1
2, when material is not conveyed toward powder material tank at ordinary times, block piece 2 is used for stopping that wind send pipe 10 in feed pipe 1, when needs are to powder
When tank apoplexy send material, need operating personnel to lift block piece 2, can just make wind send the feed end 1 that pipe 10 is plugged in feed pipe
On.Block piece support is connected with feed pipe 1, and block piece support includes the U-tube folder 3 being installed on feed pipe 1 and jointed shaft
7, the axis of jointed shaft 7 is vertical with the axis of feed pipe 1, jointed shaft 7 be provided with for for U-tube folder 3 two ends correspondence through
Perforation, U-tube folder 3 end thread be connected with for 7 block of jointed shaft coordinate so that jointed shaft 7 is anchored on feed pipe
Clamp nut 5 on 1.Block piece 2 is U-board structure of the deck on feed pipe 1, two side plates of U-board structure be located at into
The corresponding both sides of expects pipe 1, the end of two side plates of U-board structure be provided with for being hinged that jointed shaft 7 is articulated and connected
Hole, jointed shaft 7 and hinge hole form articulated structure, and block piece 2 is with spacing with the feed end of feed pipe 1 for stopping that wind send pipe
10 are plugged in the stop position I on feed pipe(Fig. 1)With remove after send pipe 10 to be plugged on the feed end of feed pipe 1 for air feed
Remove position II(Fig. 2), block piece 2 is located at when stopping position, the base plate of U-board structure with for the charging aperture of feed pipe 1
The limiting section with partial occlusion charging aperture of 9 spacing cooperation of opening's edge.
One side plate of block piece 2 is provided with travel switch 4 of the contact 6 towards jointed shaft 7, and travel switch forms control unit
To judge the position of block piece 2 to control the unlatching of deduster, contact 6 forms trigger unit to part, circumferentially arranged on jointed shaft 7
There is relief region, on jointed shaft 7, the 6 corresponding groove 8 of contact with travel switch 4 being circumferentially provided with along which, groove 8 is for one section
It is not the groove of the whole annular along 7 circumference of jointed shaft, groove 8 and the shaft portion that is hinged between 8 two ends of groove are formed
Relief region, groove 8 form recess, and the shaft portion that is hinged between 8 two ends of groove forms convex portion.Travel switch 4 is located in block piece 2
When being located at off working state when stopping position, the contact 6 of travel switch 4 is in normally closed shape in the presence of the convex portion of jointed shaft 7
State, now the spring after contact 6 compressed, travel switch 4 disconnects, when block piece 2 by stop position go to remove when, contact 6
Upspring in groove 8 under the action of the spring, the now control of travel switch 4 deduster work.
The course of work of the present utility model is:When not entering sector-style in powder material tank and sending operation, i.e., block piece 2 is located at and stops
Position, deduster does not work, and when needing wind to send operation, block piece 2 is first lifted by needs, send pipe 10 and 1 grafting of feed pipe by wind
Connection, while block piece is lifted, block piece 2 is rotated counterclockwise around jointed shaft 7, and block piece 7 is gone to by stop position and removes position,
The contact 6 of travel switch 4 stretches into groove 8 under the action of the spring, and now travel switch control roof scrubber is opened, when wind send
When operation is finished, extract wind and send pipe 10, block piece 2 to fall under gravity, block piece 2 is rotated clockwise, block piece 2 is by moving
Open position goes to stop position, and spring is compressed, and contact 6 is depressed into compression position again.
In other embodiment of the present utility model, jointed shaft can also be welded on feed pipe, and jointed shaft can be
One and the lower section of feed pipe is welded in, jointed shaft can also be two and be welded in the opposite sides of feed pipe;On block piece
Travel switch can also be not provided with, can be arranged on block piece or be had and work as block piece in stop position and remove switching between position
When for travel switch contact top pressure coordinate auxiliary section, now travel switch be not provided with block piece;On jointed shaft
Groove can also be not provided with and projection is set, now convex to form convex portion, in the circumferential direction of jointed shaft between raised two ends
The shaft portion that is hinged form recess, raised and recess forms relief region;Control unit can also include infra-red ray detection device
And controller, infra-red ray detection device be used for detect block piece position, signal is reached into controller, controller and deduster then
Control connects the unlatching to control deduster;Control unit can also include the pressure being arranged on the limiting section of U-board structure
Sensor and the controller being connected with pressure sensor signal, controller are used for controlling the unlatching of deduster.
A kind of embodiment phase of the feed arrangement in the embodiment of feed arrangement and a kind of each embodiment of above-mentioned powder material tank
Together, here is omitted.
