Abstract

The invention discloses oil-free twin-screw gas-energy compression grain drying equipment, which comprises a compressor body and a compression chamber, wherein the compression chamber is arranged in the compressor body, a compression screw rod 1 and a compression screw rod 2 horizontally penetrate through the compression chamber, the transmission blades on the compression screw rod 1 and the compression screw rod 2 are mutually engaged, the right ends of the compression screw rod 1 and the compression screw rod 2 are rotatably connected to the inner wall of the right end of the compressor body, the left ends of the compression screw rod 1 and the compression screw rod 2 penetrate through the left end surface of the compressor body, the left end of the compression screw rod 1 is provided with a driven gear, the left end of the compression screw rod 2 is connected to the output end of an asynchronous motor, a driving gear penetrates through the compression screw rod 2, and is engaged with the driven gear, and the outer side surface of the compressor body is provided with a heat dissipating groove. According to the present invention, the oil-free twin-screw gas-energy compression grain drying equipment has characteristics of simple and reasonable structure, improved material drying effect, energy saving, environment protection and strong practicability, and eliminates the traditional chemical heating methods such as coal burning and the like.

Description

technical field [0001] The invention relates to a drying equipment, in particular to an oil-free twin-screw air energy compression grain drying equipment. Background technique [0002] In order to ensure the storage time of the grain, it is necessary to dry the grain. When drying, heating equipment is required to provide heat for the intake air. The air heater is a heating equipment that mainly heats the gas flow, also known as a pipeline gas heater. , which is widely used in aerospace, weapon industry, chemical industry and living fields. The hot air produced by the air heater is dry, moisture-free, non-conductive, non-combustible, non-explosive, non-chemically corrosive, non-polluting, safe and reliable. The heated space heats up quickly, therefore, the hot air generated by the air heater can be applied to the drying of various materials, such as grain, chemical raw materials, tobacco leaves, food, etc., and can also provide a constant temperature for greenhouses such as a...

Problems solved by technology

[0003] At present, in the prior art, the heating devices used for drying various materials and supplying heat to greenhouses such as aquaculture and crop cultivation mainly use coal-fired boilers. It can be understood that coal-fired boilers are used for heating. Not only the energy consumption is high, the air is polluted, but also the utilization rate of heat is low, which cannot meet the needs of energy saving and environmental protection.
