Specific implementation mode

As shown in figs. 1-7, wet method acetylene calcium carbide of unloading automatically is crushed explosion-proof type dehumidifying and without dust stratification dust pelletizing system includes：Roller shutter Door 1, doorjamb 2, control switch 3, conducting wire 4, reel 5, gear 6, rack 7, electromagnetic coil 8, spring 9, iron core 10, shell 11, Power supply 12, conducting wire 13, speed-regulating switch 14, motor 15.

The both sides of the edge of the rolling screen door 1 are snug fit in the guide groove 201 of the doorjamb 2 of its both sides, and rolling screen door 1 is wound In the outside of the reel 5 of 2 upside of doorjamb, one end of reel 5 is coaxially fixedly connected with a gear 6, gear 6 and one side Rack 7 be sequentially connected, the upside of doorjamb 2 is additionally provided with rolling screen door control device, and rolling screen door control device includes shell 11, outside The outside of shell 11 is equipped with electromagnetic coil 8, is sliding combined with an iron core 10 in shell 11, the spring that one end of iron core 10 passes through compression 9 are fixedly connected with the inner wall resilient engagement of shell 11, the other end of iron core 10 with the end of the rack 7 penetrated in shell 11.

Electromagnetic coil 8 in the rolling screen door control device is switched with the control of power supply 12, rolling screen door respectively by conducting wire 13 3, the speed-regulating switch 14 of the motor 15 of driving exhaust fan operating and control motor 15 is electrically connected, wherein rolling screen door control device An electrical circuit, rolling screen door control device and speed-regulating switch 14, motor 15,12 groups of power supply are formed with control switch 3, power supply 12 At another electrical circuit.Speed-regulating switch 14, motor 15 are connected in electrical circuit, and speed-regulating switch 14, motor 15 and control switch 3 are simultaneously Connection.It is all knob rheostat to control switch 3 and speed-regulating switch 14, can change its resistance value by the rotation of knob, to change Become current value therethrough, the break-make of its place circuit can also be controlled by controlling switch 3 and speed-regulating switch 14, have switch work( Energy.

The course of work of the rolling screen door 1 includes：

1, control switch 3 is opened, the current loop of control switch 3, power supply 12 and rolling screen door control device, electromagnetic wire are connected Circle 8 generates electromagnetic force after being powered, and to make iron core 10 overcome the elastic force of spring 9, iron core 10 is made to be moved to the left in shell 11, after The knob of continuous rotation control switch 3, makes its resistance value reduce, to make the electric current in the electrical circuit increase, is produced in electromagnetic coil 8 Raw electromagnetic force is also synchronous to be increased, and iron core 10 is made to continue to be moved to the left, and iron core 10 will drive gear 6 to revolve counterclockwise by rack 7 Turning, gear 6 drives 5 rotating Vortex of reel, reel 5 to wind rolling screen door 1, so that the rolling screen door 1 is lifted up and wound by reel 5, Finally rolling screen door 1 is made to fully open.The truck for transporting material easily passes in and out the discharge region in the rolling screen door 1.

2, closing control switch 3, under the elastic force effect of spring 9, iron core 10 moves right and gear 6 is driven to revolve clockwise Turn, gear 6 drives reel 5 to rotate clockwise, the rolling screen door 1 that reel 5 is wound before being unfolded by it, to keep rolling screen door 1 complete Full expansion, to close the rolling screen door 1.Discharge zone where truck is isolated with the external world to come.

3, truck starts discharging, and a large amount of dust will be generated in discharge process, opens speed-regulating switch 14, and motor 15 is made to drive Fan blade rotates, to extract the dust generated in discharge region out by fan.According to the yield of dust in region, adjusts and adjust Fast switch 14, to the rotating speed of corresponding regulation motor 15 and the rotating speed of fan blade.As shown in figure 5, when the electricity of speed-regulating switch 14 When resistance declines, where electric current in electrical circuit increase, to the electric current in making the rotating speed of motor 15 increase and electromagnetic coil 8 Increase, electromagnetic coil 8 increases the magnetic force that iron core 10 generates, and so that rack 7 is moved to the left and reel 5 is driven to rotate counterclockwise, volume 5 pairs of rolling screen door 1 of cylinder generate winding effect.To make rolling screen door 1 generate certain lifting capacity, the bottom end and ground of rolling screen door 1 it Between there is certain gap, the discharge zone of 1 inside of rolling screen door can be entered from gap convenient for extraneous air, improve discharge zone Air quantity accelerates the efficiency that dust aspirates from fan.The size in the gap and the rotating speed of motor 15 synchronize increase or reduce, from And keep the intake of gap corresponding with the exhaust air rate of fan, while the gap for being also prevented from 1 lower section of rolling screen door is excessive, makes one Dust is divided to leak to the external world from gap.

As a preferred embodiment, the groove 16 there are one set depth is arranged on the ground 17 of 1 downside of rolling screen door, work as rolling screen door After 1 completely closes, the lower end of rolling screen door 1 is stretched into the groove 16, in discharge process, adjust speed-regulating switch 14 when, rolling screen door 1 Lower end in the groove 16 move without being lifted away from ground 17.As indicated by the arrows in fig. 6, extraneous air is under rolling screen door 1 Pass through in gap between end and groove 16, since extraneous air first flows downward along groove and pass through the lower end of rolling screen door 1 Edge, then air flowed up again along groove and enter the discharge zone of the inside of rolling screen door 1.The process of groove is flowed through in air In, there is the mutation in direction in the flow direction of air, the flow velocity of air in a groove faster, to more have while increasing intake Gap location of the dust of 1 inside of rolling screen door between rolling screen door 1 and groove 16 is prevented to effect to leak to the external world.

Wet method acetylene is unloaded automatically, and to be crushed explosion-proof type dehumidifying without dust stratification dust pelletizing system further include change in ventilation shaft to calcium carbide At diameter（The place that diameter changes）And elbow setting compressed gas stenciling head 20 is turned to, the compressed gas stenciling head 20 Structure is as Figure 7-8 comprising the lower part of air inlet pipe 21, air inlet pipe 21 is equipped with stenciling head ontology 22, and stenciling head ontology 22 is Hollow structure, inner cavity are connected with air inlet pipe 21.The lower end of stenciling head ontology 22 is equipped with multiple spray-holes 23, each spray-hole 23 All it is connected with the inner cavity of stenciling head ontology 22.The sealing of the air inlet pipe 21 is arranged on the tube wall of ventilation shaft, air inlet pipe 21 Outer end stretch out and ventilation shaft and be connected to high-pressure gas pipeline.

It can be more easily at the reducing of ventilation shaft and steering elbow deposition using compressed gas stenciling head 20 Dust carries out jetting deashing, prevents the dust for being deposited on these positions from generating flow resistance to the air-flow in ventilation shaft.Meanwhile Deashing is carried out using compressed gas stenciling head 20, also eliminates at the reducing of ventilation shaft and turns to elbow and carry out manual cleaning Process, alleviate the labor intensity of worker.

Obviously, above-described embodiment is only intended to clearly illustrate the utility model example, and is not to this reality With the restriction of novel embodiment.For those of ordinary skill in the art, may be used also on the basis of the above description To make other variations or changes in different ways.There is no necessity and possibility to exhaust all the enbodiments.And these Belong to obvious changes or variations that the spirit of the utility model is extended out still in the scope of protection of the utility model Among.
