Prevent skid.
The electronic striker plate 3 is located in the back edge of 1 loading and unloading material grid 2 of dump skip, is hinged on and is unloaded by hinge 3-1
On the bottom square steel of 4 frame of hopper dust suction chamber, the reciprocating motion of two electric pushrod 3-2 by being distributed in striker plate two sides,
Realize the upright and accumbency of electronic striker plate 3；The bottom end of electric pushrod 3-2 is fixed by the hinged-support being fixed on dump skip 1, electricity
The head position of dynamic push rod 3-2 is articulated on striker plate, and electric pushrod 3-2 and striker plate and dump skip headwall form four bar machines
Structure；Striker plate restores accumbency state to unload Chinese herbaceous peony upright after unloading, not under the influence of vehicle to be unloaded pass through.
The ash bucket 11-6 of the bottom of the hypocentrum 11-2 of cyclone separator 11 can prevent the dust settled again by under
Swirling eddy agitation rotation in centrum 11-2 is taken away by outlet air air-flow upwards；Inner cylinder 11-3 has cut off upper shell 11-1 and has gone out
The direct connection of wind spiral case 11-4；Air inlet 11-8 makes dusty gas in the work of outward turning spiral case by air inlet spiral case 11-7 air inlet
Enter upper shell 11-1 with tangent line after lower acceleration rotation, plays the role of reducing entrance friction, improves dustfall efficiency.Ash-laden gas
After stream enters cyclone separator 11 by tangent line air inlet 11-8, air-flow rotates in cyclone separator 11, in air-flow
Grit is mobile to outer wall under the action of the centrifugal force, reaches wall surface, and fall into ash bucket along wall under air-flow and gravity and reach
Isolated purpose, the overwhelming majority of swirling eddy are moved to cone bottom from top to bottom in the shape of a spiral along wall circular cylinder body,
The outward turning dust-contained airflow of decline is formed, density is far longer than the grit of gas by generated centrifugal force in strong rotary course
It gets rid of to wall, grit is once contacted with wall, just loses inertia force and by the momentum of entrance velocity and the gravity of itself along wall surface
It falls and enters dust collecting box 16；The air-flow declined after reaching cone bottom is rotated to transfer along the axis part of cyclone separator
Upward forms the interior rotational airflow risen, and is discharged by the exhaust pipe of cyclone separator 11, from another fraction of air inlet person who lives in exile
Air-flow is then flowed at cyclone separator upper cover plate 12-4, is then flowed downward on the outside of exhaust pipe, when reaching exhaust pipe lower end
When, i.e., it is discharged together from exhaust pipe on counter steer with the central gas stream of rising, also companion is pulled away grit dispersed therein.
Dusty gas after the entrance of sack cleaner entrance, is entered each unit room by diversion pipe, greatly by bag filter 12
Fall directly into ash bucket after granule dust separation, remaining dust with air-flow even into the filter bag 12-5 in filter chamber 12-3, when containing
When dust and gas body passes through filter bag 12-5, dust is attracted on filter bag 12-5, and cleaned gas is discharged out of filter bag 12-5.
Electromagnetic impulse valve 12-9 is opened when the dust being adsorbed on filter bag 12-5 reaches certain thickness, air is from filter in injection tube 12-7
Opposite direction of the bag exit from top to bottom with gas discharge enters filter bag 12-5, and by being adsorbed on, the dust outside filter bag 12-5 is clear
It drops down onto following ash bucket and is sent out using ash-transmission system.
Bag filter 12 is coupled using spring piston ring with card using lower air inlet, outside filtering type filter type, filter bag 12-5,
Form the separation of cleaned air and dusty gas；Electromagnetic impulse valve is sent a signal to by pulse control instrument 12-10 in deashing
12-9(import), compressed air is sprayed by injection tube 12-8, filter bag 12-5 radial deformation is made to shake off dust.Top sets access hole
12-11, for overhaul and change bag (maintenance of deduster, overhaul, change bag work only need to outside machine it is just executable, it is not necessary to enter and remove
Inside dirt device), deduster is equipped with insulating layer, top rain-proof shelter, prevents the generation and protection of dew condensation phenomenon at ambient conditions from removing
Dirt device top device, it is each that the air inlet on air jet pipe 12-8 can effectively be such that the dusty gas into deduster is uniformly distributed in
Filter bag 12-5 prevents collision and friction in deashing process between filter bag, is conducive to the extension of life of bag filter.
Dusty gas enters ash bucket under the action of air-introduced machine attraction, and each filter bag is evenly distributed to after deflector
On 12-5.Dust is intercepted at filter bag outer surface, and gas then passes through filter bag, the outlet after air-purifying chamber.Intensively in filter bag appearance
Dust on face will lead to the reduction of filter bag gas permeability, be continuously increased the resistance of deduster, until to reach setting value (poor for resistance
Voltage-controlled system) or filtering time reach setting value (time control), the electromagnetic impulse valve 12-9 for being generally in closed state exists
The control of pulse control instrument 12-8PLC pulse jet is lower to open very short a period of time (0.1s or so), high pressure gas moment from
Gas bag enters injection tube, and high speed is sprayed from injection hole.It is that can also generate to be several times as much as injection gas that high-speed flow, which sprays into filter bag,
Secondary drainage.The collective effect of jet-stream wind and secondary drainage increases the pressure on the inside of filter bag rapidly, and filter bag 12-5 is by original
The shape of indent becomes the shape of evagination, and a very big backward acceleration is generated when deflection reaches maximum value, absorption
The dust on filter bag 12-5 mainly this backward acceleration effect under, be detached from filter bag surface, fall into ash bucket, the resistance of deduster
Decline therewith.Dust is known as deashing from the process that filter bag surface is removed.Deashing work carries out by rows.Electromagnetic pulse
The every movement of valve 12-9 is primary, and row's filter bag just obtains deashing.Electromagnetic impulse valve 12-9 at set time intervals with sequence according to
Secondary movement, until completing a circulation.Whole deduster just completes a cleaning cycle.
When laden truck is unloaded by the hydraulic flap that the discharge grate 2 above dump skip 1 enters on lift dust suction chamber 7
Behind 10 designated position of machine, electronic striker plate 3 is vertical straight after trucks entering discharge grate 2, and electronic striker plate 3 is material when preventing discharging
Excessive, driver evacuates to outside dust suction chamber at this time, and operation front and back electric rolling door 8 closes front and back electric rolling door, leads to simultaneously
It overregulates and mends wind shutter 9, the start-up operation of hydraulic flap car unloader 10 is gradually lifted angle, and truck is made to tilt discharging, discharging
Dust caused by material connect with telescopic dust hood 6 by lifting dust collecting room 7 and enters dump skip dust suction chamber 4 in the process
After side dust hood 4-3 and top dust hood 4-4 collects, dust enters the cyclone separator of primary dust removing by dust ventilating net 14
It is dusted in 11, since 9 wind-supplying mouth of blinds is arranged by near-car head position two sides in lifting dust collecting room 7, wind can be from blinds wind-supplying mouth
Into lifting dust collecting room 7 and dust is taken away by telescopic dust hood 6 into 4 the aspiration of negative pressure main pipeline of dump skip dust suction chamber, is passed through
Enter bag filter 12 after 11 primary dust removing of cyclone separator and carry out two-stage dust removal, dust is separated by deduster with wind laggard
Enter dust collecting box and be collected processing, bag filter exhaust outlet dust concentration discharges meet the requirement of environmental protection；Discharging finishes end-dump car
Machine platform 10-1 playback, blinds wind-supplying mouth are closed, and electronic striker plate 3 fell closings, the opening of two sides electric rolling door 8, Si Jijin
Enter truck and sail out of operation area, discharging terminates.
