Description

A kind of grain drier

Technical field

The utility model relates to a kind of drying equipment, especially relates to a kind of grain drier.

Background technology

The northern area of China grain yield increases year by year, and the demand of drying equipment is also increasing, and existing dry technology and equipment one are that small scale, function are few, efficient is low, drying capacity is not enough; The 2nd, mostly be universal equipment, cause drying back quality heavy losses during drying grain, grade descends, and has caused the certain economic loss, influences the enthusiasm that grain operating division adopts drying equipment.

The utility model content

In order to solve the problems referred to above that grain drier exists, the utility model main purpose is to improve dried grain quality, adopt the drying process of combined bidirectional air-supply mixed flow simultaneously, system's model is basic point with big-and-middle-sized, improve disposal ability and operating efficiency, cut down the consumption of energy and operating cost, and have global function, whole process, all weather operations ability.

The utility model adopts following technical scheme:

A kind of grain drier, comprise topmost grain storage section, be connected grain storage section below last dryer section, be connected the dryer section below ventilation section, be connected the ventilation section below following dryer section, be positioned at dryer section both sides down the inlet and outlet air compartment, be connected down the dryer section below cooling section, be connected the cooling section below the cleaning section, be connected a grain discharging section below the cleaning section, be connected below the grain discharging section and be positioned at the base of foot, each building block is made up of structural steel frame and special requirement high-quality galvanized steel plain sheet, and the fabricated structure bolt connects.

High and low level detector is housed, always to be full of material in the assurance machine in the grain storage section.

Establish 16 row's grain rollers in the grain discharging section, drive by buncher, but its rotating speed step-less adjustment.

Ventilation duct in the ventilation section adopts sealing horn shape tubular structure.

Described grain drier also comprises temperature and the electric control system that is arranged in the base.

The beneficial effects of the utility model are uniform drying, efficient height, energy consumption is low, adaptability is strong, simple to operate, use reliable and easy maintenance, be applicable to large-scale grain processing center, seed processing factory and large-scale farm drying at various crops such as corn, wheat, paddy rice.

Among the figure, 1, grain storage section; 2, go up dryer section; 3, ventilation section; 4, following dryer section; 5, inlet and outlet air compartment; 6, cooling section; 7, cleaning section; 8, grain discharging section; 9, base

The specific embodiment

With reference to Fig. 1, grain drier of the present utility model comprises compositions such as grain storage section 1, last dryer section 2, ventilation section 3, following dryer section 4, inlet and outlet air compartment 5, cooling section 6, cleaning section 7, grain discharging section 8, base 9 from top to bottom by the grain direction of motion.

Grain storage section 1 is positioned at the drying machine topmost, forms by structural steel frame and special requirement high-quality galvanized steel plain sheet, and the fabricated structure Bolt Connection, intensity is good, and high and low level detector is housed in the grain storage section 1, always is full of material in the assurance machine, to prevent to heat air " short circuit ".

Last dryer section 2 is connected the below of grain storage section 1, form by structural steel frame and special requirement high-quality galvanized steel plain sheet, the fabricated structure Bolt Connection, intensity is good, it is the main drying nest of drying machine, adopt the horn shape tubular structure, thereby and change the air intake direction by ventilation section and make into, the exhaust angular tube changes, with the material that guarantees the drying machine left and right sides in whole dry run, can access consistent air quantity and blast, on sidewall, adopt the version of half angular tube simultaneously, avoid " dead band ", material is more fully mixed, reach the purpose of even drying.

Ventilation section 3 is connected the below of dryer section 2, forms by structural steel frame and special requirement high-quality galvanized steel plain sheet, and the fabricated structure Bolt Connection, intensity is good, and ventilation duct adopts sealing horn shape tubular structure.Grain does not contact with adding hot-air in this part, can play " tempering " effect, guarantees drying quality.

Following dryer section 4 is connected the below of ventilation section 3, and its structure and material are identical with last dryer section 2.

Inlet and outlet air compartment 5 is positioned at the left and right sides of dryer section 4 down, form by structural steel frame and special requirement high-quality galvanized steel plain sheet, the fabricated structure Bolt Connection, intensity is good, the thick heat preservation rock of 50mm is equipped with in the outside, whole machine body is decorated with corrosion-resistant zinc-plated " colored steel " outward, finishes the heating and the moisture discharge effect of grain.

Cooling section 6 is connected down the below of dryer section 4: be made up of structural steel frame and special requirement high-quality galvanized steel plain sheet, the fabricated structure Bolt Connection, intensity is good, adopts the horn shape tubular structure, cooling section can reduce cereal temperature and be beneficial to storage, simultaneously grain also precipitation on a small quantity in cooling procedure.
