Fig. 2 is the partial enlarged drawing at I place among Fig. 1.
Fig. 3 is the partial enlarged drawing at II place among Fig. 1.
Embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is described further:
Like Fig. 1, Fig. 2 and shown in Figure 3, a kind of reciprocal feeding type high concentration powder producer comprises launching tube 11 and wind guiding tube 13, and the air inlet 13a of wind guiding tube 13 is connected with fan blower 14, and launching tube 11, wind guiding tube 13 and fan blower are fixedly connected with frame 16.
The top of launching tube 11 has been disposed radially axle sleeve 10, is provided with in the axle sleeve 10 to send out dirt bar 9.The endoporus 10a of axle sleeve 10 is a shoulder hole, and the aperture of this shoulder hole lower end is greater than the aperture of upper end.Send out the minimum-value aperture of the diameter of dirt bar 9 less than axle sleeve 10 endoporus 10a.Can select to send out the size of dirt bar according to institute detection fly-ash separator air quantity size, what big air quantity was just selected minor diameter for use sends out the dirt bar, and air quantity is little just selects large diameter dirt bar for use.
The top of axle sleeve 10 is provided with dust stratification jar 7, and the top of dust stratification jar 7 is provided with orienting sleeve 18.The upper end screw thread of sending out dirt bar 9 is connected with the reciprocating movement rod 5 with orienting sleeve 18 clearance fit.The upper end of reciprocating movement rod 5 passes dust stratification jar 7, and the lower end is positioned at dust stratification jar 7.Dust stratification jar 7 is communicated with through axle sleeve 10 with launching tube 11.The top of dust stratification jar 7 is provided with material stock dish 6; The feed opening of material stock dish 6 is corresponding with the charging aperture of dust stratification jar 7.
The upper end of reciprocating movement rod 5 is fixed with Bearing Installation seat 17, is provided with rolling bearing 4 in the Bearing Installation seat 17, and rolling bearing 4 rolls with eccentric wheel 3 and contacts.The excircle of eccentric wheel 3 is provided with anti-derailing groove 3a, and rolling bearing 4 contacts with eccentric wheel 3 in anti-derailing groove 3a.
During powder producer work, launching tube 11 is connected with the inlet scoop of fly-ash separator, removes bottom 19; Open original dip hatch 15; And below original dip hatch 15, establish and place the dust-containing disc (not shown), in dust stratification jar 7, put into dust to be measured, start buncher 1 and fan blower 14.
Reciprocating movement rod 5 drives a dirt bar 9 and moves reciprocatingly under the effect of eccentric wheel 3 and spring 8, therefore the dust in the dust stratification jar 7 is injected into launching tube 11 from the gap of sending out between dirt bar 9 and the axle sleeve 10.Wherein, eccentric wheel 3 utilizes different eccentric throws back and forth ceaselessly the spring 8 of reciprocating movement rod 5 lower ends to be carried out periodic compression, release, to realize reciprocating movement rod 5 and the at the uniform velocity to-and-fro movement of sending out dirt bar 9.When eccentric throw was in maximal value downwards, spring 8 was compressed, otherwise spring 8 is released when eccentric throw is in minimum value downwards; When reciprocating movement rod 5 from the moment of low side to high-end rapid movement; To form an instantaneous vacuum chamber in dirt bar 9 upper end; The vacuum chamber internal pressure is much smaller than atmospheric pressure; Therefore the dust in the dust stratification jar 7 will move to vacuum chamber under the atmospheric pressure effect, and a dirt bar 9 dust is on every side reached capacity; To produce a kind of suction that makes progress at the gap location of sending out dirt bar 9 and axle sleeve 10 simultaneously and fall into launching tube to stop dust dust when reciprocating movement rod 5 moves upward; The cyclical movement that does not so stop is sent dust into launching tube clocklike, uniformly, sends out the dirt precision to improve.
After dust gets into launching tube 11; Under the effect of fan blower 14, get into fly-ash separator from launching tube; Simultaneously; When the rotating speed rotational speed regulation of buncher 1 to appropriate frequency, after stable operation half a minute to part dust to be measured evenly falls into the dust-containing disc (not shown) from original dip hatch 15, can carry out the former dust concentration that starts and measure.Can repeatedly measure the dust quality that falls in the dust-containing disc of dip hatch below when waiting, get its mean value as the former dust concentration that starts.
More than describe preferred embodiment of the present invention in detail.Should be appreciated that those of ordinary skill in the art need not creative work and just can design according to the present invention make many modifications and variation.Therefore, all technician in the art all should be in the determined protection domain by claims under this invention's idea on the basis of existing technology through the available technical scheme of logical analysis, reasoning, or a limited experiment.
