Description

Modular splicing type automatic grain drying tower
Technical Field
The invention belongs to the technical field of grain drying equipment, and particularly relates to a modularized spliced automatic grain drying tower.
Background
With the improvement of grain seeds, the improvement of unit yield and the increase of investment of the state on grain drying equipment, more and more large, medium and small grain drying facilities are built, grain drying is a necessary step before grain storage, and usually a medium such as hot air is injected into a drying tower and then water vapor is discharged.
Current grain drying tower includes: the tower body, the lifting mechanism, the material receiving mechanism and the heat supply device; the existing grain drying tower has some problems, and the following problems exist:
firstly, the tower body of the existing grain drying tower is an integral body, so that the transportation is very inconvenient, and the tower body needs to be disassembled and then welded and assembled to a destination; in addition, once the tower body is manufactured, the tower body can only be used for grain drying operation with the standard tonnage, for example, the tower body with the grain capacity of 10 tons can only be used for drying operation of grain below 10 tons at a time, and the expansion performance of the tower body is weak; the existing grain drying tower mostly adopts the heat supply at the bottom of the tower, the drying form of the dehumidification at the top of the tower, the grain drying temperature at the bottom is too high, the high temperature is easy to deteriorate, the grain drying temperature at the top is lower, the drying effect is unsatisfactory, the grain drying temperature at the middle part is moderate, but the moisture is discharged out of time, the long-term storage at the later stage is easy to deteriorate, and the design of the tower body of the existing grain drying tower is totally improved.
Secondly, after grains such as wheat, rice, corn, soybean and other crops are harvested, grain purchasing units or grain storage units need to dry the grains to prevent the grains from mildewing in order to quickly recover the grains from the warehouse, and then the dried grains are put into the warehouse. The lower end of the existing drying equipment is provided with a material receiving bin, and grains dried by the drying equipment are collected after passing through the material receiving bin. The material receiving bin is provided with only one outlet, if the grains are not completely dried, the collected grains which are not dried are conveyed to the drying equipment through the hoister, so that the efficiency is obviously reduced, the labor intensity is high, and the large-scale continuous drying of the grains is not facilitated.
With the continuous development and progress of science and technology, the production and the processing of grain realize automation and mechanization gradually, and this makes the machining efficiency of grain obtain great improvement, and grain drying elevator is exactly one of the mechanical equipment that is used for grain drying processing, and current grain drying elevator has some problems and defects: the traditional grain drying and lifting machine can cause more damage to grains and cannot meet the use requirement; the traditional grain drying hoister cannot adjust the tightness of a conveying belt and is poor in durability; the traditional grain drying and lifting machine is inconvenient to control the feeding amount and use.
At present, a gas hot-blast stove is generally adopted to provide heat for a drying tower in the grain drying process. The structure of the gas hot-blast stove is characterized in that combustible gas is combusted in a combustion chamber to heat normal-temperature air, and the hot air is formed and then is sent into a drying tower by a draught fan. The structure can not solve the problem of the proportioning of the gas quantity and the air quantity in the combustion process, so that insufficient combustion and waste of gas are caused, and meanwhile, residual flame or sparks can enter a grain drying tower to cause potential safety hazards; on the other hand, the temperature in the combustion chamber is difficult to control, and the grain is damaged due to the overhigh temperature of the discharged hot air.
The existing grain drying tower can not be added and used continuously, and further can not increase the drying tonnage, and when equipment with larger drying tonnage is needed, the original grain drying tower can be eliminated, thereby causing resource waste.
