The effective flying dust remaining carbon checkout equipment of a kind of anti-clogging is equipped with, and comprises sampling unit, measuring unit and control module, and sampling unit is connected by the interior receipts apparatus for ash of receipts ash pipe and measuring unit; In measuring unit inside, along the circumferential direction uniform four crucibles on the turn device, receive apparatus for ash, firing device and ash exhauster lay respectively at crucible directly over, weighing device be positioned at crucible under, jacking gear is provided with push rod, receipts apparatus for ash, ash exhauster, turn device, jacking gear all are connected with electric device with weighing device, and firing device connects with temperature controller; Measuring unit is connected with control module by electric device; Described receipts apparatus for ash comprises receives ash pipe and holder; Be provided with electromagnetic vibrator on holder, the vibration head of electromagnetic vibrator contacts with the outer wall of receiving ash pipe.
Wherein, be provided with backing plate between described electromagnetic vibrator and the holder.
Wherein, described backing plate is the vibrationproof backing plate.
Beneficial effect: the effective flying dust remaining carbon checkout equipment of anti-clogging of the present utility model is by installing electromagnetic vibrator additional receiving the ash pipe outside, the dither that relies on electromagnetic vibrator to produce drives receives grey tube wall vibration, effectively prevent to receive the ash pipe blockage phenomenon, guaranteed ash pipe blanking smoothness, and the normal operation of checkout equipment.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is for receiving the structural representation of apparatus for ash.
Embodiment:
Below in conjunction with accompanying drawing the utility model is done further explanation.
As shown in Figure 1, the flying dust remaining carbon checkout equipment that anti-clogging of the present utility model is effective comprises sampling unit 1, measuring unit 2 and control module 3.
Sampling unit 1 comprises the stopple coupon 4 of speaking out of turn, playpipe 5 and cyclone dust collector 6; Stopple coupon 4 one ends of speaking out of turn put in the boiler flue, and the other end is communicated with the air intake opening of cyclone dust collector 6, and cyclone dust collector 6 upper end playpipes 5 are communicated with, and cyclone dust collector 6 lower ends are connected by receiving ash pipe 8 and measuring unit 2 interior receipts apparatus for ash 7.
In measuring unit 2 inside, along the circumferential direction uniform receipts ash, calcination on the turn device 12, weigh and four station holes of ash discharge, in the station hole, place crucible 11; Receive apparatus for ash 7, firing device 9 and ash exhauster 10 lay respectively at crucible 11 directly over, weighing device 14 be positioned at crucible 11 under; Jacking gear 13 is provided with and receives ash, calcination and the corresponding push rod of ash discharge fabrication hole; Receipts apparatus for ash 7, ash exhauster 10, turn device 12, jacking gear 13 all are connected with electric device 15 with weighing device 14, and firing device 9 is connected 16 and connects with temperature controller; Measuring unit 2 is connected with control module 3 by electric device 15.
As shown in Figure 2, receive apparatus for ash 7 and comprise receipts ash pipe 20, holder 21, stage clip 22, pilot pin joint 23, gland 24, column 25, backing plate 26 and electromagnetic vibrator 27; Receive ash pipe 20 and be arranged on the holder 21, holder 21 is fixed on column 25 upper ends; Be provided with pin-and-hole and gland 24 at the feed opening end of receiving ash pipe 20, vertically be provided with gathering sill on the gland 24, pilot pin joint 23 is fixed in the pin-and-hole by gathering sill, makes gland 24 produce relative slip with receiving ash pipe 20 along gathering sill, is used for regulating the relative position of gland 24 and feed opening; Be provided with stage clip 22 on receipts ash pipe 20 outer walls between gland 24 and the holder 21, the pressure by stage clip 22 makes closely contact between the crucible 11 in gland 24 and the measuring unit, to stablize crucible 11; When receiving ash, under the effect of receiving grey push rod, the O-ring seal at the receipts ash head place of crucible 11 and receipts ash pipe 20 compresses, and prevents the ash sample leakage.
