By the Automated condtrol of science, impact of the tempering to feeding system in rotary kiln can be to greatest extent reduced.
Exemplary embodiment
Fig. 1 shows a kind of structural representation of the feeding system of danger wastes of embodiment of the present utility model.Under
Face specifically describes the feeding system with reference to Fig. 1.
According to embodiment of the present utility model, a kind of feeding system 100 of danger wastes includes the hopper for setting gradually
10th, chute 30, feed dolly 40, feeder channel 50, the pneumatic gate valve that is arranged between the hopper 10 and the chute 30
20 and the fire prevention gate 60 of the feeder channel end is arranged on, as shown in Figure 1.
Wherein, the hopper 10 is used to receive material；The vertical section of the hopper 10 is right-angled trapezium；The right-angled trapezium
It is wide at the top and narrow at the bottom；The hopper 10 is made up of carbon steel material.The pneumatic gate valve 20 is by ball valve and solenoid valve control.Institute
Chute 30 is stated for axially symmetric structure.The feed dolly is the device of the promotion material of danger wastes CIU.It is described to give
Material passage is the passage for being fed moving of car.The fire prevention gate 60 is by solenoid valve control.
Operation principle of the present utility model is：When the pneumatic gate valve 20 between hopper 10 and chute 30 is opened, prevent
Fiery gate 60 is closed, and the danger wastes material that Jing is fully pre-processed is grabbed to hopper 10 by grab bucket, or is passed through
Chain bucket is poured onto in hopper 10, and danger wastes material falls in feeder channel after hopper 10 further through chute 30
In 50；Now pneumatic gate valve 20 is closed, and fire prevention gate 60 is in open mode, and feed dolly 40 travels forward, and feed is logical
Danger wastes material in road 50 is pushed in rotary kiln to carry out being pyrolyzed/burning completely, and feed dolly 40 reaches furthest travel
After start to move backward, or when be fed dolly 40 move to its front end encounter fire prevention gate 60 when, feed dolly 40 stop fortune
Dynamic, gate 60 of now preventing fires is changed into closed mode from open mode, and feed dolly 40 starts to retreat, when the front end of feed dolly 40
When backing to initial position, pneumatic gate valve 20 is changed into open mode from closed mode, reenters and treats material state.
The utility model is poor in order to solve the problems, such as anti-backfire effect present in prior art, using pneumatic gate valve 20
Replace turnover plate type valve of the prior art, while employing fire prevention gate 6, be allowed to realize preventing back together with pneumatic gate valve 20
The dual security protection of fire, by the Automated condtrol of science, can to greatest extent reduce tempering in rotary kiln is to feed
The impact of system 100.
The utility model in order to solve danger wastes material severe corrosion equipment present in prior art and charging system
Regiment commander's material, the problem for getting stuck, lay PTFE plates on the header board of hopper 10, and the PTFE plates of increase can prevent the danger of highly corrosive
Dangerous discarded object material is directly contacted with the header board of hopper 10, to reduce corrosion of the danger wastes material to steel plate, so as to increase
The service life of hopper 10；Simultaneously danger wastes are not easy to be adhered on PTFE plates, and strip and the problem for getting stuck also can be obtained
Improve；In addition, danger wastes are not easy to be adhered on PTFE plates, this can further reduce the wind that danger wastes corrode steel plate
Danger.On the other hand, because danger wastes are not easy to be adhered on PTFE plates, compared with prior art, the header board of hopper 10 with
The angle of horizontal direction can suitably reduce, and can so make danger wastes material fall the initial velocity in feeder channel 50,
To reduce impact of the danger wastes material to feeder channel 50, so as to reduce the risk that feeder channel 50 is hit and deforms.
Further, the PTFE plates can be fixed on the steel plate of the hopper 10 by sunk screw, to prevent PTFE
Plate is hit and deforms.It should be noted that also PTFE plates can be fixed using any method well known to those skilled in the art
On the steel plate of hopper 10.
Further, the thickness of the PTFE plates is 8-12mm, preferred 10mm.The numerical value only as an example, can be according to concrete
Situation is suitably adjusted.
The utility model is smaller in size than to further solve the problems, such as strip and getting stuck using the bottom interface of hopper 10
The design of the top interface size of the chute 30, the bottom interface size of hopper 10 and the top interface of chute 30 with prior art
The connection of the sizes such as size is compared, and this design can greatly reduce danger material and be adhered the possibility on pneumatic gate valve 20,
So as to improve the strip and the problem that gets stuck that are caused by pneumatic gate valve 20.
The utility model in order to further solve the problems, such as strip and to get stuck, also using chute 30 bottom sectional area ratio
The big design of sectional area at top, compared with the straight barrel type structure of prior art, using this up-small and down-big design, can make danger
Dangerous discarded object material is adhered the possibility on the inwall of chute 30 and reduces, and asks with getting stuck so as to improve the strip brought by chute 30
Topic.
The utility model is poor in order to solve the problems, such as anti-backfire effect present in prior art, there is provided a kind of dangerous useless
The feeding system of gurry, the utility model replaces turnover plate type valve of the prior art using pneumatic gate valve, while employing
Fire prevention gate, is allowed to realize anti-backfire dual security protection together with pneumatic gate valve, by the Automated condtrol of science, energy
It is enough to reduce impact of the tempering to feeding system in rotary kiln to greatest extent.
Additionally, the utility model is in order to solve danger wastes material severe corrosion equipment present in prior art and enter
Material system strip and the problem for getting stuck, are equipped with PTFE plates on the header board of hopper, the PTFE plates of increase can prevent highly corrosive
Danger wastes material directly contact with the steel plate of hopper, to reduce corrosion of the danger wastes material to steel plate；Endanger simultaneously
Dangerous discarded object is not easy to be adhered on PTFE plates, and strip and the problem for getting stuck also can be improved.
The beneficial effects of the utility model are：
The 1st, a kind of new safe and stable, reliable, effective feeding system is provided.
2nd, by using pneumatic gate valve and fire prevention gate dual security protection, solving the problems, such as that feed system is tempered.
3rd, by laying PTFE plates on the header board of hopper, perishable hopper header board and feed system strip, card are solved
The problem of material.
4th, compared with prior art, the header board of hopper can suitably reduce with the angle of horizontal direction, so can reduce
The initial velocity that danger wastes material falls in feeder channel, the risk deformed with reducing feeder channel to be hit.
5th, by being smaller in size than the design of the top interface size of the chute 30 using the bottom interface of hopper 10, can be with
Further solve the problems, such as strip, get stuck.
6th, by the design that the sectional area of the bottom using chute 30 is bigger than the sectional area at top, band can further be solved
Material, the problem for getting stuck.
