Material caused by closing action crushes, so as to reduce the breakage rate of material.
Step 6, discharging：
When PLC control modules detect that the opening time of the air-breathing automatic switch valve 24 of first cyclone separator 2 reaches
To after the purge time set in PLC control modules in advance, PLC control modules first cyclone separator 2 of closing goes out
Wind automatic switch valve 25, and open the discharging automatic switch valve 22 of first cyclone separator 2.First cyclone separator 21
Interior material is discharged to follow-up equipment under the effect of gravity.
Step 7, discharging automatic shape valve is purged：
When the material of the deposition in the cyclone separator 21 that material-level detecting device 4 detects first cyclone separator 2
When being highly down to pre-set low material position in PLC control modules, the low material position information detected is transferred to PLC control moulds
Block, PLC control modules close the air inlet automatic switch valve 23 and air-breathing automatic switch valve 24 of first cyclone separator 2, and
Open the outlet air automatic switch valve 25 of first cyclone separator 2 in part.Air is under the air inducing effect of wind turbine 3 by first
The bottom of cyclone separator 21 enters first cyclone separator 21, when air passes through discharging automatic switch valve 22, to discharging certainly
Dynamic switch valve 22 generates purging effect, and the material caused by avoiding the switching motion of follow-up discharging automatic switch valve 22 crushes, from
And it further reduced the breakage rate of material.
The air inlet automatic switch valve 23 and air-breathing automatic switch valve 24 of first cyclone separator 2 are first closed, is then turned on
The outlet air automatic switch valve 25 of first cyclone separator 2, can improve the air capacity by discharging automatic switch valve 22, from
And purging effect of the air to discharging automatic switch valve 22 is improved, so as to again reduce the breakage rate of material.
The outlet air automatic switch valve 25 of first cyclone separator 2 is opened in part, can avoid outlet air automatic switch valve 25
It opens excessive, the material in follow-up equipment is caused to be raised again by wind turbine 3, is played a reversed role into first cyclone separator 21.
Step 8, valve is closed：
When PLC control modules detect that the opening time of the air-breathing automatic switch valve 24 of first cyclone separator 2 reaches
To after the purge time set in PLC control modules in advance, PLC control modules first cyclone separator 2 of closing unloads
Expect automatic switch valve 22 and outlet air automatic switch valve 25, the work period of first cyclonic separation dress completes.
Step 9, second cyclone separator 2 repeats the above steps 4~step 8,2 alternate cycles work of cyclone separator
Make, realize the automatic continuous operation of conveying device.
It is to be noted that first cyclone separator, 2 and second whirlwind point described in the embodiment of the utility model
From device 2 in structure and functionally identical or similar, cyclone separator 2 works alternatively, and differentiation nominally is used only as describing
When differentiation.In addition to firm start-up phase, the cyclone separator 2 for carrying out step 4~step 8 is filled for first cyclonic separation
2 are put, the cyclone separator 2 for carrying out step 1~step 3 is the second cyclone separator 2.
The way of realization that content described in this specification embodiment only conceives utility model is enumerated, this practicality is new
The protection domain of type is not construed as being only limitted to the concrete form that embodiment is stated, the scope of protection of the utility model also and
In those skilled in the art according to the utility model design it is conceivable that equivalent technologies mean.
