Embodiment
As shown in Figure 1, present embodiment comprises part of detecting and control output, the present invention's material when work enters part of detecting, by the sensor acquisition information in the part of detecting, and information sent to the control output, single-chip microcomputer by the control output is handled the data that record, and controls the duty of part of detecting in real time, the data presentation output after will handling at last.
As shown in Figure 2, part of detecting comprises stepper motor 1, and stepper motor 1 is connected with volume adjusting apparatus 2, being provided with barretter 4 below the volume adjusting apparatus 2, is provided with blower fan 3 in the last barretter 4, and blower fan 3 directly is connected with power supply.Be provided with filter screen 5 in the bottom of last barretter 4, filter screen 5 is connected with last barretter 4 by the fixing seal device.The lower end of last barretter 4 links to each other with the upper end of conically shaped 7, is provided with several sensors 8 around the inwall in the conically shaped 7, and the lower end of conically shaped 7 is connected with afflux cover 11 by following barretter 9.The quantity of the sensor 8 can be selected according to the real work needs, promptly can select three, five, eight, ten even more.
As shown in Figure 3, Figure 4, the volume adjusting apparatus 2 that is adopted in the present embodiment is whole for circular, and its radius is slightly larger than the radius of barretter 4, and it comprises two-layer up and down, the two-layer up and down strip baffle plate that all has, the strip baffle plate evenly distributes, and guarantees that with this air outlet is can air-out even.The folding of two-layer up and down strip baffle plate is by stepper motor 1 control.As shown in Figure 3, when volume adjusting apparatus 2 was operated in complete closure state, two-layer up and down strip baffle plate was interspersed.Along with the rotation of stepper motor 1, two-layer up and down strip baffle plate intersects, overlaps.When two-layer strip baffle plate was in coincidence status up and down, volume adjusting apparatus 2 was operated in the complete opening state, as shown in Figure 4.
Because little at afflux cover 11 place's bores, wind speed is big, for the buoyancy that makes material equates with gravity, is equilibrated at certain altitude, and then can accurately measure its floating velocity, so the radius on its top should be greater than the radius at afflux cover 11 places.For above-mentioned reasons, adopt conically shaped 7 among the present invention, the wind speed of arbitrary height is by the wind speed of bell and highly decision in the conically shaped 7.Blower fan 3 is with rated power work, and the aperture area size of volume adjusting apparatus 2 air outlets has determined the wind speed of conically shaped 7 lower surface bells.The aperture area size of air outlet is accurately controlled and feed back to stepper motor 1.Simultaneously, in order to regulate material inlet velocity and velocity of discharge, thus all need to be provided with barretter at the two ends up and down of conically shaped, and the shape of barretter should be selected for use cylindrical.
As Fig. 5, shown in Figure 6, enter blower fan 3 for preventing dust and the little material of part proportion in the material, be provided with filter screen 5 in the bottom of last barretter 4.Above-mentioned fixing seal device comprises filter screen hoop 12, handle 6, rubber weather strip 13, buckle ring 14 and filter screen button 15.Filter screen 5 is fixed in the filter screen hoop 12, between filter screen hoop 12 and the handle 6 rubber weather strip 13 is housed, an end of rubber weather strip 13 is buckle rings 14, and the other end is a filter screen button 15, such design is easy to disassembly, cleaning, prevents because filter screen 5 uses and the ventilating air permeability variation for a long time.Be provided with a square groove in the inside of last barretter 4, the consistency of thickness of the height of square groove and filter screen hoop 12.When packing filter screen 5 into, this square groove plays guide groove.This square groove prevents filter screen 5 under the effect of air-flow, vertical tremor to the fixation of 5 vertical directions of filter screen after packing into.After filter screen 5 is loaded onto, earlier buckle ring 14 is buckled on the protruding a16 of barretter 4, the filter screen button 15 with the other end is buckled on the protruding b17 of barretter 4 opposite sides then, compresses to fasten rubber weather strip 13 and tighten, and finishes the installation of filter screen 5.Above-mentioned filter screen 5 and fixing seal device thereof can play fixation to filter screen 5 on the one hand in surface level, rubber weather strip 13 can be sealed the slit between square groove and the filter screen hoop 12 on the other hand, prevent gas leakage.
Control output in the present embodiment comprises single-chip microcomputer and computing machine, and single-chip microcomputer links to each other with stepper motor 1, blower fan 3 and the sensor 8 of part of detecting respectively, and single-chip microcomputer is connected with computing machine.Send instruction by computing machine, after single-chip microcomputer received this instruction, the running of monitoring and control step motor 1 with this folding size of controlling volume adjusting apparatus 2, was finally controlled the air quantity size.Blower fan 3 is with rated power work, and its startup and shutdown are by Single-chip Controlling.Whether sensor 8 real-time detections have material to pass through conically shaped, and measure the hoverheight of material, and the various data that while sensor 8 will collect are passed to single-chip microcomputer and handled, and single-chip microcomputer is handled back demonstration in computing machine and exported.
The principle of work and the course of work of present embodiment are:
Behind the opening device, at first material to be measured is placed on the opening part of afflux cover 11, Single-chip Controlling stepper motor 1 is opened volume adjusting apparatus 2 gradually by closed state, wind speed also changes from small to big gradually, when the air door aperture area of volume adjusting apparatus 2 reaches certain state, be the upwards attractive force that is subjected to of material during greater than own weight, material begins to move upward, and enters conically shaped 7.Meanwhile, after slave unit was opened, whether the sensor 8 around conically shaped 7 inwalls scans always had material to pass through in the conically shaped 7.If there is not material to pass through, then strengthen the air door aperture area of volume adjusting apparatus 2 gradually by stepper motor 1; If there is material to pass through, then determine the concrete levitation position of material.In the time of thus the rotation situation of stepper motor 1 as can be known this moment volume adjusting apparatus 2 aperture area, and then can determine the wind speed at conically shaped 7 bell places, automatically calculate the floating velocity of material at this moment by the hoverheight of material by single-chip microcomputer again, and show by the display of computing machine.
Present embodiment as different from Example 1, in the present embodiment, the bottom of last barretter 4 is provided with filter screen 5, filter screen 5 is connected with last barretter 4 by the fixing seal device.Above-mentioned fixing seal device is the viscose agent, utilizes the viscose agent directly filter screen 5 to be sticked on the inwall of barretter 4.Project organization is simple relatively like this.
The other technologies feature is identical with embodiment 1.
Present embodiment in the control output of present embodiment, has also comprised printer apparatus as different from Example 1, and printer is connected with computing machine, is used for the data in real time that computing machine draws is printed.Above-mentioned printer and driving circuit thereof are technology well known to those of ordinary skill in the art.
The other technologies feature is identical with embodiment 1.
Present embodiment as different from Example 1, at the part of detecting of present embodiment, last barretter 4 is fixedlyed connected with support 10, above-mentioned support 10 is an A-frame.Because when work, the part of detecting vibrations are bigger, the design of A-frame can be played stabilization to the device of this part of detecting.
