Abstract
The utility model relates to a two-grade spiral type biomass solid particles delivery device, which mainly comprises a group of low speed screw feeder and a group of high speed screw feeder. The low speed screw feeder transports the material to the high speed screw feeder and then the high speed screw feeder transports the material to a high temperature reactor. The rotation speed of the low speed screw feeder is no higher than 100 rounds per minute while the rotation speed of the high speed screw feeder is no lower than 1000 rounds per minute. The two-grade spiral type biomass solid particles delivery device avoids unsmooth feeding or even blocking caused by that the biomass material is softened in a high temperature environment and adhered into the inner wall of the screw feeder, thus enhancing the production efficiency. The device is simple in structure, safe and reliable in operation and low in transportation cost.
Description
Technical field
The utility model belongs to the conveying machinery field, is specifically related to a kind of two-stage screw biomass solid particle feedway.
Background technology
For equipment such as biomass combustion, gasification and liquefaction, generally all require its feed system swimmingly biomass solid particle quantitatively to be sent in the high temperature reactors such as burning, gasification and liquefaction continuously.Prior biological matter particulate matter screw feeding device, it mainly is made up of barrel and single step helical feeder.Wherein, barrel is used for holding biomass solid particle; Feeding screw is used for biomass solid particle is quantitatively sent into high-temperature reactor.But such feed arrangement usually can stop up in operation process; be difficult to swimmingly biomass solid particle be sent in the high-temperature reactor continuously; because high temperature reactors such as feeding screw and burning, gasification and liquefaction directly link; its internal temperature is generally all more than 200 ℃; and the lignin in the living beings can soften when 200 ℃ of left and right sides, and the living beings after softening very easily stick on the inwall of feeding screw and make feeding not freely until stopping up.
The utility model content
The purpose of this utility model is to provide a kind of biomass solid particle that makes can be transported to quantitative delivery technology of a kind of two-stage screw and device in the high temperature reactors such as burning, gasification and liquefaction continuously swimmingly.
Technical solution of the present utility model is as follows
A kind of two-stage screw biomass solid particle feedway comprises: barrel 1, last material blanking tube 2, gate 3, upper motor 4, upper transmission system 5, slow spin feeder 8, following material blanking tube 9, the next motor 6, the next transmission system 7, high-speed screw feeder 10;
Last material blanking tube 2 upper ends and barrel 1 are communicated with, and its lower end and slow spin feeder 8 are communicated with, and the top of last material blanking tube 2 is equipped with gate 3; The clutch end of the power intake of upper transmission system 5 and upper motor 4 is rigidly connected, and the power intake of the clutch end of upper transmission system 5 and slow spin feeder 8 is rigidly connected;
The upper end of following material blanking tube 9 and slow spin feeder 8 are communicated with, and lower end and high-speed screw feeder 10 are communicated with; The clutch end of the power intake of the next transmission system 7 and the next motor 6 is rigidly connected, and the power intake of the clutch end of the next transmission system 7 and high-speed screw feeder 10 is rigidly connected; The delivery port of high-speed screw feeder and high-temperature reactor 11 are communicated with;
The rotating speed of slow spin feeder 8 is smaller or equal to 100r/min; The rotating speed of high-speed screw feeder 10 is more than or equal to 1000r/min.
Useful technique effect of the present utility model is: owing to adopted high speed low speed two-stage screw biomass solid particle feedway, avoided latch up phenomenon effectively, thereby biomass solid particle can be transported in the high temperature reactors such as burning, gasification and liquefaction continuously swimmingly, and apparatus structure is simple, safety of operation reliable, it is with low cost to carry.

Specific embodiments
A kind of two-stage screw biomass solid particle feedway comprises: barrel 1, last material blanking tube 2, gate 3, upper motor 4, upper transmission system 5, slow spin feeder 8, following material blanking tube 9, the next motor 6, the next transmission system 7, high-speed screw feeder 10.
Last material blanking tube 2 upper ends and barrel 1 are communicated with, and lower end and slow spin feeder 8 are communicated with, and the top of last material blanking tube 2 is equipped with gate 3; The clutch end of the power intake of upper transmission system 5 and upper motor 4 is rigidly connected, and the power intake of the clutch end of upper transmission system 5 and slow spin feeder 8 is rigidly connected;
The upper end of following material blanking tube 9 and slow spin feeder 8 are communicated with, and lower end and high-speed screw feeder 10 are communicated with; The clutch end of the power intake of the next transmission system 7 and the next motor 6 is rigidly connected, and the power intake of the clutch end of the next transmission system 7 and high-speed screw feeder 10 is rigidly connected; The material delivery port of high-speed screw feeder and high-temperature reactor 11 are communicated with.
The rotating speed of slow spin feeder 8 is not higher than 100r/min; The rotating speed of high-speed screw feeder 10 is not less than 1000r/min.
Screw feeding device with fluidized bed type biomass particulate matter equipment for gasification is an example, if the biomass solid particle inlet amount is that 100kg/h, bulk density ρ are 100kg/m
3The screw rod outer diameter D of first order feeding screw is that 100mm, inner diameter d are that 50mm, lead of screw S are that 40mm, spiro rod length are 1.0m, then screw speed is the requirement that 47r/min can satisfy the quantitative charging of biomass solid particle, and the move axially speed of cooresponding therewith biomass solid particle in feeding screw has only 0.03m/s, thereby moves to the other end from one section of screw rod and approximately need 33s.If second stage feeding screw construction parameter identical with first order feeding screw, but screw speed is 1450r/min, the move axially speed of then cooresponding biomass solid particle in feeding screw is 0.93m/s, moves to the about 1s that only needs of the other end from one section of screw rod, shortened greatly biomass solid particle with second stage feeding screw that high-temperature reactor directly links to each other in heated time, thereby can make the biomass solid particle before having enough time to be warmed up to softening point, promptly do not sent into high-temperature reactor continuously swimmingly.
Experiment shows that biomass solid particle two-stage screw delivery technology provided by the present invention and device can quantitatively be sent into biomass solid particle in the high temperature reactors such as burning, gasification and liquefaction continuously swimmingly.
