Problems solved by technology

And existing feeder, its structure sees figure 1 , when feeding, the material is easy to be stuck between the rotor and the U-row bucket, so there will be a large leakage space between the rotor and the U-row bucket, and the long-term closure of the gap will easily lead to the backfire of the boiler. , causing a fire in severe cases

Embodiment Construction

[0008] see figure 1 , figure 2 , The present invention includes the jack shaft 10, the jack shaft 10 is mounted on the shaft sleeve 13, the shoulder of the jack shaft 10 is in clearance fit with one end of the shaft sleeve 13, and an end sleeve is provided between the other end of the jack shaft 10 and the other end of the shaft sleeve 13 12. A spring 11 is press-fitted between the end sleeve 12 and the shaft shoulder. The end shoulder of the top shaft 10 is press-fitted on the end sleeve 12, and the flange outer diameter of the end sleeve 12 is larger than the inner diameter of the shaft sleeve 13. The working process of the present invention is described below in conjunction with the drawings: a large amount of material is poured from the hopper mouth, the rotor is driven by the motor to rotate rapidly, after the blades disperse the material, the material is stored between the rotor blades 6, under the rotation of the rotor 6 Bring it out to realize the feeding of the boiler. W...

Abstract

The invention relates to an improved anti-blockage device used for crushed straw aggregates feeding machine, which can timely close the space between a rotor and the U-shaped funnel so as to realize the air locking of the boiler and reduce the possibility of fire hazard. The device is characterized by comprising an apical axis which is installed on a bushing, the shoulder of the apical axis is matched with a clearance at one end of the bushing, a pot head is arranged between the other end of the apical axis and the other end of the bushing, a spring is arranged between the pot head and the axis shoulder in a pressing way, the axis shoulder at the end part of the apical axis is arranged on the pot head in a pressing way, and the external diameter of the flange of the pot head is larger than the internal diameter of the bushing.

Description

(1) Technical field [0001] The invention relates to the technical field of storage equipment for materials used in a biomass combustion furnace, in particular to an improved anti-blocking device for a straw scrap feeder. (2) Background technology [0002] With the declining energy, biomass fuel has increasingly become another fuel source in the boiler industry. Due to the particularity of biomass fuel itself, its large size, space occupation, and inconvenient storage, a star feeder has been designed in the industry, which can quickly disperse the accumulated materials to meet the requirements of the boiler. However, because the boiler is a negative pressure furnace, it is required that the feeder be able to lock the gas while feeding to prevent backfire. The structure of the existing feeder is figure 1 When feeding, the material is easy to be stuck between the rotor and the U-row bucket, so there will be a large leakage space between the rotor and the U-row bucket, and the long-...
