The specific embodiment
Like the biomass electric power plant feed bin of Fig. 1 to a kind of anti-raw material obstruction shown in Figure 3; This feed bin is made up of superposed square feeding warehouse 1, the square intermediate bunker 2 that is positioned at the middle part that goes out feed bin 3 and connect feeding warehouse 1 and go out feed bin 3 that is positioned at the bottom; Intermediate bunker 2 is the truncated rectangular pyramids warehouse of up big and down small gradual shrinkage; Vertically be built-in with two pushing plate 4 in the feeding warehouse 1, these two pushing plate 4 opposites are provided with, and two pushing plate 4 all are connected with push rod 5; Push rod 5 passes the back from the sidewall of feeding warehouse 1 and links to each other with driver train; Pushing plate 4 can promote the biomass material that falls in the feeding warehouse 1 in the moving process under driver train and push rod 5 effects, destroys the natural accumulation form of biomass material, fully the biomass material of piling up is carried out disturbance from the bottom; Simultaneously raw material is carried toward the blanking channel at middle part, reached the effect that prevents raw material built, stable feed.Pushing plate 4 is as the movable wall of feed bin, and the moving range of pushing plate 4 is from the centre of inwall to the feeding warehouse that is fitted in feeding warehouse 1.Pushing plate 4 can change driving velocity and actuating length according to actual inventory of feed bin and conveying situation under the driver train effect.
Feeding warehouse 1 in the present embodiment with go out feed bin 3 cross-sectional planes and be square, intermediate bunker 2 is positive truncated rectangular pyramids warehouse, has 45 ° tilt angle alpha between the side of intermediate bunker 2 and the horizontal surface; Each piece pushing plate 4 in two pushing plate 4 all is connected with 5, two push rods 5 of two push rods and is up and down that shape distributes, and this driver train is two motors, and each motor links to each other with a pushing plate 4 pairing two push rods 5 respectively, and drive push rod 5 moves.
The whole height of the utility model feed bin is 5m, last minister 3m, and the long 1.2m of sloping portion, feed bin width are 4m, the angle of inclination is 45 °.Feed bin adopts conventional steel plates to process the feed bin main body, can use the thin steel plate of size to process as the pushing plate 4 of feed bin movable wall.The material storage capacity can cause conveying not smooth because of putty or the mutual built of storeroom more for a long time in feed bin, so pushing plate 4 promotes down toward the inner promotion of feed bin at push rod; Can the biomass material that be deposited in the feed bin be compressed toward the feed bin middle part, destroy its natural accumulation form, quicken its blanking velocity; Effectively solve problems such as bridging putty, and increased the alerting ability of feed bin, reach efficiently, the effect of transferring raw material stably; And can prevent effectively that raw material from stopping up; Be specially adapted to stalk, the straw equidimension is longer, easily the biomass material of building bridge takes place in winding screw setting gauge easily.
The utility model feed bin working process is following: the biomass electric power plant feeding system is at first transported to biomass material in the feed bin from material blanking tube through belt conveyor; Under the effect of pushing plate; Material is transported to the feeding screw of feed bin bottom uniformly and stably from blanking channel, and then the entering CFBB burns.
Present embodiment can be done like down conversion, and said intermediate bunker is positive truncated rectangular pyramids warehouse, the tilt angle alpha that has between the side of intermediate bunker and the horizontal surface can be between 45 °～75 ° value.
Present embodiment can be done like down conversion, and said driver train is a motor, and this motor is connected with four push rods of two pushing plate simultaneously, drives four same moved further of push rod.This motor can adopt motors such as buncher, servomotor.
