Description

Movable small drier

This movably minitype drier is to be used for grain withering machinery in postpartum.Be applicable to that the area that grain should not focus on postpartum, production scale is relatively disperseed not quite again uses.It can dry wheat, corn, soybean, cereal that the paddy rice equigranular is bigger, also can dry granule crops such as rapeseed, international Patent classificating number F26B17/00.

In recent years, domestic grain is dried the multidirectional concentrated batch production direction of treatment technology and develop postpartum, promptly build the grain processing center of batch production, therefore, that dryer mostly is is medium-and-large-sized, drying capacity is bigger, drying capacity was all in (as introducing Berico 930 types of the U.S., the homemade Great Northern Wilderness-15 type etc.) more than 15 tons in general hour.Minitype drier (hour drying capacity is below 5 tons) also has certain research, but Shang Weiyou can change movably minitype drier of operating location, and China's agricultural production region complicated production scale varies.Big-and-middle-sized dryer relatively adapts to the bigger grain fixed point oven dry of concentrated production scale to be handled.For producing relatively dispersion, small so that remote production unit is just urgent especially to the demand of small-sized movably dryer.

The purpose of the utility model research and design provides a kind of transfer tasks place of drawing, and is good by performance, the dry technology index is good, and thermal efficiency height is suitable for drying varigrained cereal, satisfy the outlying district, the minitype drier of the agriculture unit demand that production disperses, scale is less.

The technical characterictic of this movably minitype drier is: it comprises hoisting mechanism, oven dry main frame, wind sector, the mechanism that puts out cereal, shifting of conveyer structure and the monitoring of material temperature etc. partly.Its elevator 1 is folding, helping traction passes through, oven dry main frame 4 has multilayer in dryer section, corresponding half angular tube that big oblique angle is housed with the air intake angular tube on every layer the sidewall, adopt the structure of the double angular tube air draft of single angular tube air intake at cooling section 13, the air-cooler 9 of wind sector adopts negative pressure induced wind and simultaneously as waste heat recovery, air-heater 8 adopts the malleation air blast, and the hot blast of its hot blast and waste heat recovery together enters hot-flow flue; The row's grain roller 11 of mechanism of putting out cereal is 6 leaf rollers, below row's grain roller, be provided with vertical collection grain screw feeder 10, its helical blade is divided into two sections, its helical blade rotation direction is opposite, the cereal that collection is pushed is moved by inward at both ends, the screw feeder 15 of laterally putting out cereal is divided in segmentation place (apart from 1/3 place of tail end) that vertically collects the grain screw feeder in correspondence, receives the cereal of being discharged by vertical screw feeder segmentation place and pushes output; What be connected with horizontal screw feeder output is the oblique screw feeder 16 of putting out cereal, and is used for irritating bag or outward transport grain in bulk; The shifting of conveyer structure is by rectangular frame and tripod formula installing base frame and the double as traction chassis 19 that forms a whole, each assembly of dryer is installed on it, transport by the tripod traction during transfer, with 5 fulcrum vertical shaft 17 positioning supports that are installed on the traction chassis, these 5 fulcrum vertical shafts are adjustable helical axis during operation; Central part at delay section 14 is provided with the warm monitoring sensor of material; Between elevator 1 and oven dry main frame, be provided with and climb ladder 18; In order to prevent mixing of different cereal or baked seed, vertically collect grain screw feeder 10 and the drain pan structure of the screw feeder 15 of laterally putting out cereal is that segmentation can be rolled over housing, in order to cleaning.

Advantage of the present utility model:

Complete machine can draw the transfer tasks place, and joint is collapsible on its elevator, has reduced shipping height, makes door beam when entering setting, lowly sets up thing obstacle does not take place;

5 adjustable positioning supports axles, supporting ﹠ stablizing not only can guarantee simultaneously when the operation scene of injustice the complete machine leveling is guaranteed the normal operation performance;

Adopt six leaf roll row grains, row's grain speed even, envelope grain is effective when stopping arranging at random, no natural leak phenomenon;

The inside and outside lateral section of hot blast angular tube is long-pending different, and is big near the cross section of sidewall, improved the situation of being heated of the wet grain of sidewall, improved the uniformity of oven dry;

Same blower fan is adopted in cooling and waste heat recovery, and rate of recovery height has improved the complete machine thermal efficiency.
