Dust discharging system for combustion chamber of grain drying hot air equipment

Abstract

The invention discloses a dust discharging system for a combustion chamber of grain drying hot air equipment, and belongs to the technical field of agricultural equipment. The dust discharging systemcomprises a combustion chamber base, a dust unloading motor, a combustion chamber base frame, a dust unloading fan and a dust unloading mechanism; the combustion chamber base is arranged at the upperend of the combustion chamber base frame; the dust unloading mechanism is arranged in the combustion chamber base frame and arranged under the combustion chamber base; the dust unloading fan is arranged at the left end of the dust unloading mechanism; the dust unloading motor is arranged at the front end of the dust unloading mechanism which is connected with the dust unloading motor through a chain; the combustion chamber base frame is provided with a dust unloading fan mounting frame; and the lower end of the dust unloading fan mounting frame is in threaded connection with the dust unloadingfan. The dust discharging system is high in automation degree, a high-pressure gas inlet pipe is arranged, high-pressure gas is sprayed in the tangential direction of the inner wall of a pouring layer of the combustion chamber, thus the situation that high-temperature dust is crystallized in the combustion chamber, and consequently blockage is caused is prevented, and the cost is saved; and the dust unloading mechanism conducts intermittent discharging, the dust is blown out through positive pressure, meanwhile, the dust unloading mechanism can be air-cooled, and thus the service life is prolonged.

Description

technical field [0001] The invention relates to the technical field of agricultural equipment, in particular to an ash discharge system for a combustion chamber of grain drying hot air equipment. Background technique [0002] Agriculture belongs to the primary industry. Agriculture in a broad sense refers to five industrial forms including planting, forestry, animal husbandry, fishery, and sideline industry; agriculture in a narrow sense refers to planting, including the production of food crops, economic crops, fodder crops and green manure. Activity. Whether it is agriculture in a broad sense or agriculture in a narrow sense, planting is the most important component of agriculture; as a country with a large population, the demand for food is self-evident, and it must solve the problem of feeding more than one billion people every day. Agriculture is the livelihood of the people and stability. China's social development is carried out on the premise of food and clothing. ...

AI Technical Summary

Problems solved by technology

[0003] With the development of modern industry, many aspects of grain planting, harvesting, transportation and storage have gradually become automated and mechanized, saving a lot of manpower, material and financial resources; in grain storage, drying equipment is generally used to dry grain crops. Stored after drying, the biomass particle suspension combustion hot air stove in the existing drying equipment has the advantages of environmental protection, low pollution and regeneration, and is widely used; the biomass particles will produce bottom ash after full combustion, which can be used as a construction Materials and wastes are re-used, but the existing biomass particle suspension hot blast stoves tend to produce dust high-temperature crystallization into blocks during the ash discharge process, thereby blocking the ash discharge pipeline. At this time, it is necessary to stop the machine and manually clean it after cooling. Time-consuming and labor-intensive, affecting production
