Bale breaking device of straw bale burning direct-fired biomass boiler

Abstract

The invention discloses a bale breaking device of a straw bale burning direct-fired biomass boiler. The device comprises a bale breaking roller assembly and a water cooling circulating system; the bale breaking roller assembly comprises two bale breaking roller main shaft pipes which are arranged in a straw bale breaking chamber side by side, a plurality of bale breaking thorns are uniformly arranged on the outer side wall of the ring of each bale breaking roller main shaft pipe, straw bales falling between the two bale breaking roller main shaft pipes can be broken by the bale breaking thorns, and straw can be fully burnt after being split; the water cooling circulating system can carry out continuous circulating water cooling on the two bale breaking roller assemblies positioned in the high-temperature environment of the straw bale breaking chamber and carry out cooling protection on the two bale breaking roller assemblies. The bale breaking device of the straw bale burning direct-fired biomass boiler not only can fully and thoroughly burn straw bales, but also enables the boiler temperature to be raised rapidly, is high in heat efficiency, greatly reduces labor, reduces the labor intensity, and is high in automation degree, low in fault rate and higher in practicability.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to a bag-breaking device for a direct-fired biomass boiler fired with straw bundles. Background technique [0002] At present, the existing straw bales burning boilers cannot ensure that the straw bales are fully burned. The straw bales are naturally burned in the boiler by the air supplied by the blower. [0003] Therefore, how to solve the technical shortcomings of the existing straw bundle burning boilers, and propose a straw bundle breaking device that can fully burn straw in the boiler, has high thermal efficiency, reasonable structural design, and is easy to use for direct-fired boilers. A problem urgently needed to be solved by those skilled in the art at present. Contents of the invention [0004] In view of this, in order to overcome the above-mentioned technical defects, the present invention provides a bag-breaking device for direct combustion of straw b...

AI Technical Summary

Problems solved by technology

[0002] At present, the existing straw bales burning boilers cannot ensure that the straw bales are fully burned. The straw bales are naturally burned in the boiler by the air blower, which not only has a slow combustion speed, but also has the disadvantages of incomplete combustion of straw, slow heating of the boiler, and low thermal efficiency.
