Abstract
The utility model discloses a cast house feeding device, which comprises a cast house feed bin, a kick-out screw and a spiral feeder. The cast house feed bin is in the shape of a big end down horn, the kick-out screw is located below the cast house feed bin, rice husk fuels are shifted to the spiral feeder, the kick-out screw is arranged above the spiral feeder while a boiler discharge pipe is arranged below the spiral feeder, and rice husks enter the boiler discharge pipe through the spiral feeder. The cast house feeding device effectively avoids problems that rice husks are easy to be caked and then block the cast house feed bin in the prior art, then can lead a boiler to be operated stably, and resolves series of problems that the rice husks utilized as fuels are burnt in the boiler.
Description
Technical field
The utility model relates to a kind of front feeding device.
Background technology
Rice husk is as regenerative resource, and its value of environmental protection has begun to be recognized by people with the value that can save non-renewable resources.There is the people that rice husk is directly put into existing coal-fired front feeding device for this reason, wishes that existing coal-burning boiler can be fuel with the rice husk.But because existing coal-fired front feeding device generally only is made up of the stokehold feed bin, fuel enters boiler by the boiler material blanking tube after entering the stokehold feed bin, when putting into the stokehold feed bin with rice husk, people find, because rice husk fugitive constituent height is very easy to burning, the stokehold feed bin easily returns fire burns, and rice husk nature bulk density is little, the material good water absorption, feed bin easy putty in stokehold hardens, and the instability of feeding system has a strong impact on boiler operatiopn.Therefore present boiler still can not act as a fuel with rice husk.Scientific and technical personnel are paying close attention to always and how to address this problem for this reason.
The utility model content
The purpose of this utility model be to provide a kind of can with rice husk act as a fuel and feed stable, the front feeding device that boiler can normally be moved.
This front feeding device that the utility model provides, comprise the stokehold feed bin, also comprise screw-type kickoff, screw(-type) feeder, it is up-small and down-big horn-like that described stokehold feed bin becomes, described screw-type kickoff is positioned at the below of stokehold feed bin, rice hull fuel is set aside screw(-type) feeder, and the top of this screw(-type) feeder is that the screw-type kickoff below is the boiler material blanking tube, and rice husk enters the boiler material blanking tube by screw(-type) feeder.
Leaning on stokehold one sidewall in the bin wall of described stokehold feed bin is vertical wall, and other three sidewall is toward outer incline.
Described screw-type kickoff comprises some double rotational directions spiral conveyor rods, and described screw(-type) feeder adopts four.
Described screw(-type) feeder discharge port end is provided with passage, and the tail end of this passage is connected with the boiler material blanking tube, is provided with the pneumatic fast valve in the two poles of the earth on passage.
The utility model can solve fuel bridging problem owing to adopted up-small and down-big bell mouth shape stokehold feed bin, makes the feed bin blanking unimpeded.Adopted screw-type kickoff structure and screw feeder mechanism in addition, made screw-type kickoff can effectively the fuel in the feed bin evenly be given each screw feeder mechanism, and the isometric living beings of the stalk that is mingled with in the fuel can have been cut off.The utility model front feeding device has effectively been avoided the phenomenon that rice husk easily hardens at stokehold feed bin generation putty in the prior art, thereby can make boiler operatiopn stable, has solved the serial problem that rice husk acts as a fuel and burns in boiler.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the cutaway view of Fig. 1 along the A-A line.
The specific embodiment
The utility model comprises stokehold feed bin 1, screw-type kickoff 2, screw(-type) feeder 3 as can be seen from Figure 1, the exit of screw(-type) feeder 3 is provided with passage 6, the tail end of this passage 6 is connected with boiler material blanking tube 7, is provided with the pneumatic fast valve 4 in the two poles of the earth, expansion joint 5 on passage 6.Up-small and down-big horn-like of 1 one-tenth of stokehold feed bin, and be vertical wall by stokehold one sidewall in the bin wall of described stokehold feed bin 1, other three sidewall can solve fuel bridging problem like this toward outer incline, makes the feed bin blanking unimpeded.
Fig. 2 has reflected the detailed installation site of screw-type kickoff 2, screw(-type) feeder 3.Screw-type kickoff 2 is positioned at the below of stokehold feed bin 1, rice hull fuel is set aside screw(-type) feeder 3, screw-type kickoff 2 be positioned at stokehold feed bin 1 below, it is made up of some double rotational directions spiral conveyor rods 21 and drive motors, the rotation of double rotational directions spiral conveyor rod 21 is constantly transferred to the rice husk in the stokehold feed bin 1 and evenly deliver on each screw(-type) feeder 3, screw(-type) feeder 3 can adopt many, and present embodiment has adopted four, and they can cut off the isometric living beings of the stalk that is mingled with in the fuel.The discharge port end of screw(-type) feeder 3 is connected with passage 6, and the pneumatic fast valve 4 in the two poles of the earth is housed on this passage 6, is used to control blanking, and the tail end of passage 6 is connected with boiler material blanking tube 7, and rice husk is entered burning in the boiler 8 by boiler material blanking tube 7.
