Description
Technical Field
The invention belongs to the technical field of grain drying equipment, and particularly relates to a modularized spliced grain automatic drying tower.
Background
With the improvement of grain seeds, the improvement of unit yield and the increase of investment of grain drying equipment in China, more and more large, medium and small grain drying facilities are built, and grain drying is a necessary step before grain storage, and medium such as hot air is usually used for injecting into a drying tower and then water vapor is removed.
The existing grain drying tower includes: the device comprises a tower body, a lifting mechanism, a receiving mechanism and a heating device; the existing grain drying tower has some problems, and the problems are listed as follows:
(1) the existing grain drying tower has the defects that the tower body is an integral body, the transportation is very inconvenient, and the tower body needs to be disassembled and then welded and assembled at a destination; in addition, once the tower body is manufactured, the tower body can only be used for grain drying operation by designing the tonnage of the standard, for example, the tower body with the grain capacity of 10 tons can only be used for drying operation of grains below 10 tons at a time, and the expansion performance of the tower body is weak; the existing grain drying towers mostly adopt a drying mode of tower bottom heat supply and tower top moisture removal, the bottom grain drying temperature is too high, the top grain drying temperature is low, the drying effect is not ideal, the middle grain drying temperature is moderate, the moisture is not timely discharged, the later-period long-term storage is easy to deteriorate, and in general, the design of the existing grain drying towers is to be improved.
(2) After crops such as wheat, rice, corn, soybean and the like are harvested, the grains are required to be dried by a grain purchasing unit or a grain storage unit in order to quickly harvest the grains, so that the grains are prevented from being mildewed, and then the dried grains are returned to the bin. The lower end of the existing drying equipment is provided with a receiving bin, and grains dried by the drying equipment are collected after passing through the receiving bin. The receiving bin is only provided with one outlet, if the grains are not completely dried, the collected grains which are not dried are conveyed to the drying equipment through the lifting machine, so that the efficiency is obviously reduced, the labor intensity is also high, and the large-scale continuous drying of the grains is not facilitated.
(3) Along with the continuous development and progress of science and technology, the production and processing of grain gradually realize automation and mechanization, this makes the machining efficiency of grain obtain great improvement, and grain stoving lifting machine is one of mechanical equipment that is used for grain stoving processing, and current grain stoving lifting machine has some problems and defects: the traditional grain drying and lifting machine can cause more damage to grains and can not meet the use requirement; the traditional grain drying lifter cannot adjust the tightness of the conveyor belt, and has poor durability; the traditional grain drying and lifting machine is inconvenient to control the feeding amount and is very inconvenient to use.
(4) At present, a gas hot blast stove is widely adopted in the grain drying process to provide heat for a drying tower. The gas hot-blast stove is structurally characterized in that combustible gas is combusted in a combustion chamber, normal-temperature air is heated, hot air is formed, and then the hot air is sent into a drying tower by an induced draft fan. The structure can not solve the proportioning problem of the gas quantity and the air quantity in the combustion process, so that insufficient combustion and gas waste are caused, and meanwhile, residual flame or spark possibly enters a grain drying tower to cause potential safety hazard; on the other hand, the temperature in the combustion chamber is difficult to control, and the temperature of the discharged hot air is too high, so that the grains are damaged.
(5) The existing grain drying towers cannot be increased in groups and used continuously, further the drying tonnage cannot be increased, and when equipment with larger drying tonnage is needed, the raw grain food drying towers are eliminated, so that resource waste is caused.
