Feeding conveying device of biomass boiler

Abstract

The invention discloses a feeding conveying device of a biomass boiler. The device comprises a protection cover, a mounting base, a conveying pipe, a shaking groove and a crushing tank; a supporting plate is welded to the top end of the inner side of the mounting base, the crushing tank is welded to the top of the supporting plate, the protection cover is hinged to one side of the top of the crushing tank, a feeding opening is formed in the protection cover, and a hinge shaft is arranged at the connecting position of the protection cover and the crushing tank. The output end of a motor drivesa first rotating shaft and a packing auger to rotate through a belt wheel mechanism and a first gear, the output end of the motor is connected with a movable block located in the shaking groove through a cam, the motor can be used for driving the first rotating shaft, the packing auger and the cam to rotate at the same time, the linkage is high, energy consumption is saved, in the moving process of the movable block, the shaking plate is driven to shake the material, the shaking is similar to the beating action, material loosening is facilitated, material stacking is avoided, and the materialconveying effect is improved.

Description

technical field [0001] The invention relates to the technical field of biomass boilers, in particular to a feed conveying device for biomass boilers. Background technique [0002] Biomass boiler is a type of boiler. Boilers that use biomass energy as fuel are called biomass boilers. They are divided into biomass steam boilers, biomass hot water boilers, biomass hot blast stoves, biomass heat-conducting oil Material boilers, horizontal biomass boilers, etc. [0003] In the boiler feed conveying system of biomass power plants such as straw power generation in China, most of the straw materials are crushed and sent to the front of the furnace by belt conveyors, screw conveyors and simplified hydraulic piston propulsion devices. The silo is then sent to the boiler for combustion by one or more sets of screw conveyors at the bottom of the silo in front of the furnace. [0004] At present, the feeding and conveying device of the existing biomass boiler has a complex structure, a...

Problems solved by technology

[0005] The purpose of the present invention is to provide a feed conveying device for a biomass boiler to solve the problem that the existing feed conveying device for a biomass boiler proposed in the background art has a complex structure, a large floor space, and a single function. During the process, the materials are easy to stick and block the pipeline, which affects the effect of material transportation, uneven feeding, poor linkage, and high energy consumption.
