Dust-removing dryer for grain

Abstract

The invention relates to a dust-removing dryer for grain and belongs to the field of agricultural drying machinery. The dryer comprises a box, an air heater and a purification tank, wherein water is contained in the purification tank, an air blower is arranged at the top of the box, an air outlet of the air blower is connected with an air inlet of the box, and an air inlet of the air blower is connected with the air heater through a pipeline; drying pipes are arranged in the box, a plurality of through holes are formed in the side wall of each drying pipe, and exhaust ports are formed in one side wall of the box and extend into the liquid level of the purification tank. The dust-removing dryer for the grain dries the grain in an up-ventilation and down-exhaust manner, the grain is ensured to be dried quickly and effectively, and the workload of farmers can be reduced; moisture in the grain is fully diffused, the quality of the dried grain is higher, the exhaust ports are placed in water, impurities and dust in exhaust air are adsorbed by water, pollution can be prevented, the exhaust air is purified, and the dryer is simple in structure and has very high practicability.

Description

technical field [0001] The invention relates to a grain dedusting dryer, which belongs to the field of agricultural drying machinery. Background technique [0002] my country is a big agricultural country, and the state supports the production and application of agricultural machinery. Grain purchase, storage, processing and other enterprises, agricultural professional cooperatives, and family farms all use grain dryers in large quantities, and the quality requirements for grain dryer machinery are getting higher and higher. Traditional grain dryers are not perfect in terms of drying efficiency and grain collection after drying. The contact time between grain and hot air is short, and drying is not thorough. Multiple dryings are required, which increases the work intensity of farmers. Conducive to the popularization of agricultural equipment. China is the world's largest grain producer and consumer. According to statistics, every year due to climate reasons, the grain is t...

Problems solved by technology

At present, the method of grain drying generally relies on the heat source to sprinkle the required grain under the action of gravity or machinery, and let the water slowly dissipate under the action of conduction, convection and radiation, so as to achieve the purpose of grain drying; however, The drying method is relatively complicated, the equipment consumes high energy, the level of automation is low, and the investment is large.

[0003] The existing tumble dryer is mainly composed of a hot air stove, a drying cylinder, a fan, and conveying equipment. It has a simple structure, convenient maintenance, and low cost. The drying effect of the grain is not ideal, and the output is low; at present, there is no efficient, simple, energy-saving and environmentally friendly drying machine and drying method suitable for large agricultural machinery households, large grain growers and village groups.
