The automatic intelligent unloading controller of bottom of the reservior powder
Technical field
The present invention relates to the discharging controller, be specifically related to the automatic intelligent unloading controller of a kind of bottom of the reservior powder.
Background technology
Centrifuge is adopted in traditional powder discharging, and material enters the centrifuge tripper by top, material is assigned to the inwall of vertically arranged rotary drum (cone-element) with the tripper of rotary drum high speed rotating; Material is done parabolic motion along the rotary drum (cone-element) inwall with dispersion shape from top to bottom under the effect of centrifugal force and gravity; In this motion process, material enters Rong Cang by filter screen, enters discharging opening then.There is more defective in this conveyer centrifugal: the one, and mechanism's complexity, maintenance difficult; The 2nd, the frequent adhered materials of filter screen, the cleaning difficulty is big; The 3rd, because centrifugation effect is held the inwall in storehouse and easily tied material, the volume in appearance storehouse causes packed material metering inaccurate from large to small; The 4th, hold the storehouse cleaning and need tear machine open and carry out, influence work efficiency and increase the frequency of maintaining.
Summary of the invention
The objective of the invention is to: provide a kind of bottom of the reservior powder automatic intelligent unloading controller, simple to operate, discharging is complete, accurate measurement, and maintenance is easily.
Technical solution of the present invention is: intelligent unloading controller is installed in the bottom at feed bin, this intelligent unloading controller comprises spiral gate, fluidisation goes out feed bin, discharging mouth and control valve, through spiral gate fluidisation is installed in the bottom of feed bin and feed bin, fluidisation goes out on the bulkhead of feed bin to establish air admission hole and discharging opening, the discharging mouth of three way type is installed in fluidisation and goes out on the feed bin, first end of discharging mouth is communicated with the discharging opening that fluidisation goes out feed bin, second end of discharging mouth is a blanking port, the 3rd end of discharging mouth connects control valve, described control valve is by cylinder body, piston and piston rod are formed, the two ends of cylinder body are established an air inlet and No. two air inlets respectively, cylinder body is connected on the 3rd end of discharging mouth, piston is airtight to be installed in the cylinder body, piston rod on the piston is positioned at the cylinder body center, and an end of piston rod stretches out cylinder body and penetrates the discharging mouth, and the spool sealing fluidisation of its end goes out the discharging opening of feed bin, the other end of piston rod stretches out cylinder body, and handwheel is installed in its end.
During discharging, open spiral gate, powder is pressed from being advanced into fluidisation by the feed bin material and is gone out feed bin, and fluidisation goes out feed bin and form pressure chamber under the pressure of air admission hole; A then air inlet air inlet, piston are taken piston rod and are moved right and open the discharging opening that fluidisation goes out feed bin under gas pressure, powder self gravity and the pressure effect of air admission hole under from the blanking port discharge of discharging mouth; After blowing finishes, close air inlet No. one, open air inlet No. two, piston is taken piston rod and is moved to the left and closes the discharging opening that fluidisation goes out feed bin under the effect of No. two air inlet pressure, finish discharging.
The present invention is simple in structure, and is easy to operate, and discharging is complete, accurate measurement, and maintenance is easily.

The specific embodiment
As shown in Figure 1, intelligent unloading controller is installed in bottom at feed bin 2, this intelligent unloading controller comprises spiral gate 1, fluidisation goes out feed bin 9, discharging mouth 12 and control valve, through spiral gate 1 fluidisation is installed in the bottom of feed bin 2 and feed bin 9, fluidisation goes out on the bulkhead of feed bin 9 to establish air admission hole 10 and discharging opening 11, the discharging mouth 12 of three way type is installed in fluidisation and goes out on the feed bin 9, first end of discharging mouth 12 is communicated with the discharging opening 11 that fluidisation goes out feed bin 9, second end of discharging mouth 12 is a blanking port 7, the 3rd end of discharging mouth 12 connects control valve, described control valve is by cylinder body 5, piston 6 and piston rod 13 are formed, the two ends of cylinder body 5 are established an air inlet 3 and No. two air inlets 4 respectively, cylinder body 5 is connected on the 3rd end of discharging mouth 12, piston 6 airtight being installed in the cylinder body 5, and the piston rod 13 on the piston 5 is positioned at cylinder body 5 centers, one end of piston rod 13 stretches out cylinder body 5 and penetrates discharging mouth 12, the spool 8 sealing fluidisations of its end go out the discharging opening 11 of feed bin 9, and the other end of piston rod 13 stretches out cylinder body 5, and handwheel 14 is installed in its end.
During discharging, open spiral gate 1, powder is pressed from being advanced into fluidisation by feed bin 2 material and is gone out feed bin 9, and fluidisation goes out feed bin 9 and form pressure chamber under the pressure of air admission hole 10; Then air inlet 3 air inlets, piston 6 are taken piston rod 13 and are moved right and open the discharging opening 11 that fluidisation goes out feed bin 9 under gas pressure, powder self gravity and the pressure effect of air admission hole under from blanking port 7 discharges of discharging mouth 12; After blowing finishes, close air inlet 3 No. one, open air inlet 4 No. two, piston 6 is taken piston rod 13 and is moved to the left and closes the discharging opening 11 that fluidisation goes out feed bin 9 under the effect of No. two air inlet pressure, finish discharging.
