Blocking-preventing star-shaped feeding machine

Abstract

The invention relates to the technical field of biomass burning equipment, in particular to a blocking-preventing star-shaped feeding machine which can effectively prolong the service life of a blocking-preventing device. The blocking-preventing star-shaped feeding machine comprises a rack. A feeding hopper is installed on the rack. A rotor is arranged in the feeding hopper. A rotating shaft of the rotor is perpendicular to the center line of the feeding hopper. Movable sealing plates are arranged on the two sides of the rotor correspondingly. The two movable sealing plates form a U-shaped hopper. The bottom of the U-shaped hopper is hollow. Each movable sealing plate comprises an upper end plane section and a lower end arc section, wherein the top of the upper end plane section is connected to the inner wall of the feeding hopper through a supporting rotating shaft. The blocking-preventing star-shaped feeding machine is characterized in that the outer side of each upper end plane section is provided with a blocking-preventing device, each blocking-preventing device comprises a shaft sleeve, each shaft sleeve penetrates the inner wall of the feeding hopper and is fixed through a bolt, a movable top shaft is arranged in each shaft sleeve through a spring, the end portion of each top shaft makes contact with the corresponding upper end plane section, when no blocking materials exist between the U-shaped hopper and the rotor, each top shaft is perpendicular to the corresponding upper end plane section, and rib plates are arranged between the outer sides of the shaft sleeves and the inner wall of the feeding hopper.

Description

technical field [0001] The invention relates to the technical field of biomass burning equipment, in particular to an anti-blocking star feeder. Background technique [0002] Among the biomass burning equipment, the star feeder is the most important equipment, which can quickly disperse the accumulated materials to meet the requirements of the boiler. The patent No. ZL200820216851X mentions an improved star feeder The anti-jamming machine can ensure that there will be no tempering phenomenon through an anti-jamming device, but the anti-jamming device is said to be set at the arc outside the U-shaped bucket, and the top shaft of the anti-jamming device is in contact with the arc surface. The axial direction of the top shaft and the radial direction of the arc surface are not in a straight line. When the U-shaped bucket is pushed outward by the material, the top shaft is subjected to an oblique downward thrust. Under the action of this force for a long time, the top shaft is p...

[0002] Among the biomass burning equipment, the star feeder is the most important equipment, which can quickly disperse the accumulated materials to meet the requirements of the boiler. The patent No. ZL200820216851X mentions an improved star feeder The anti-jamming machine can ensure that there will be no tempering phenomenon through an anti-jamming device, but the anti-jamming device is said to be set at the arc outside the U-shaped bucket, and the top shaft of the anti-jamming device is in contact with the arc surface. The axial direction of the top shaft and the radial direction of the arc surface are not in a straight line. When the U-shaped bucket is pushed outward by the material, the top shaft is subjected to an oblique downward thrust. Under the action of this force for a long time, the top shaft is prone to Deformation, even the entire anti-jamming device will be displaced or deformed, which will affect the service life, and the arc surface is far away from the supporting shaft of the U-shaped bucket, so when the U-shaped bucket swings, the arc surface swings relatively large, and the suit The spring on the jacking shaft is in a state of extension and contraction for a long time, and its service life is short
