Fig. 2 is the partial enlarged drawing at I place in Fig. 1.
Fig. 3 is the partial enlarged drawing at II place in Fig. 1.
Embodiment
Below in conjunction with drawings and Examples, the invention will be further described:
As shown in Figure 1, Figure 2 and Figure 3, a kind of back and forth 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 and sends out dirt bar 9 in axle sleeve 10.The endoporus 10a of axle sleeve 10 is shoulder hole, and the aperture of this shoulder hole lower end is greater than the aperture of upper end.The diameter of sending out dirt bar 9 is less than the minimum-value aperture of axle sleeve 10 endoporus 10a.Can select to send out according to detected fly-ash separator air force the size of dirt bar, what Wind Volume was just selected minor diameter sends out dirt bar, and air quantity is little just selects large diameter dirt bar.
Wind guiding tube 11 is just to being provided with original dirt dip hatch 15 under axle sleeve 10, the original dirt dip hatch 15 places end cap 19 that has been threaded.
The top of axle sleeve 10 is provided with dust stratification tank 7, and the top of dust stratification tank 7 is provided with orienting sleeve 18.Sending out the upper end of dirt bar 9 is threaded and the reciprocating movement rod 5 of orienting sleeve 18 clearance fit.The upper end of reciprocating movement rod 5 passes dust stratification tank 7, and lower end is positioned at dust stratification tank 7.Dust stratification tank 7 is communicated with by axle sleeve 10 with launching tube 11.The top of dust stratification tank 7 is provided with stock plate 6; The feed opening of stock plate 6 is corresponding with the charging aperture of dust stratification tank 7.
The upper end of reciprocating movement rod 5 is fixed with bearing mounting base 17, is provided with rolling bearing 4 in bearing mounting base 17, and rolling bearing 4 rolls and contacts with eccentric wheel 3.On the excircle of eccentric wheel 3, be provided with derailing groove 3a, rolling bearing 4 contacts with eccentric wheel 3 in derailing groove 3a.
Eccentric wheel 3 is connected with speed change gear 2, and speed change gear 2 is connected with buncher 1; Between reciprocating movement rod 5 and axle sleeve 10, be provided with spring 8.Wind guiding tube 13 is provided with wind deflector 12 near the top of axle sleeve 10.
When 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 dust-containing disc (not shown), in dust stratification tank 7, put into dust to be measured, start buncher 1 and fan blower 14.
Reciprocating movement rod 5 drives a dirt bar 9 to move reciprocatingly under the effect of eccentric wheel 3 and spring 8, therefore the dust in dust stratification tank 7 is injected into launching tube 11 from the gap of sending out between dirt bar 9 and 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 to periodic compression, release, to realize the at the uniform velocity to-and-fro movement of reciprocating movement rod 5 and a dirt bar 9.When eccentric throw is during downwards in maximal value, spring 8 is compressed, on the contrary when eccentric throw during downwards in minimum value spring 8 be released; When the moment of reciprocating movement rod 5 from low side to high-end rapid movement, to form an instantaneous vacuum chamber in dirt bar 9 upper end, vacuum chamber internal pressure is much smaller than atmospheric pressure, therefore the dust in dust stratification tank 7 will move to vacuum chamber under atmospheric pressure effect, make to send out dirt bar 9 dust around and reach capacity; To produce a kind of suction upwards to stop dust dust in the time that reciprocating movement rod 5 moves upward to fall into launching tube at the gap location of sending out dirt bar 9 and axle sleeve 10 simultaneously, so ceaselessly cyclical movement by regular dust, send into launching tube uniformly, send out a dirt precision to improve.
Dust enters after launching tube 11, under the effect of fan blower 14, enter fly-ash separator from launching tube, simultaneously, when the rotating speed rotational speed regulation of buncher 1 is to appropriate frequency, stable operation half a minute to part dust to be measured evenly falls into 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 falling 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 just can design according to the present invention make many modifications and variations without creative work.Therefore, all technician in the art, all should be in by the determined protection domain of claims under this invention's idea on the basis of existing technology by the available technical scheme of logical analysis, reasoning, or a limited experiment.
