Abstract
The invention discloses a ventilation mesh plate of a grain dryer. The ventilation mesh plate is a plate body formed by knitting wires latitudinally and longitudinally, wherein knitting holes of the plate body are meshes; the longitudinal wires knitted latitudinally and longitudinally are straight wires; some latitudinal wires are spirally wound wires, while the others are the straight wires; the longitudinal straight wires are threaded between two adjacent spiral coils of each spirally wound wire in parallel; and the longitudinal straight wires and the latitudinal straight wires are knitted into crossed shapes. The meshes of the ventilation mesh plate are relatively smaller, have high density and are distributed uniformly in all directions, so the ventilation mesh plate completely meets the requirement of heat-moisture exchange between a hot air channel and a grain channel in a dryer room, and compared with the prior art, effectively improves the rate of heat exchange of the dryer room and speeds up drying grains.
Description
Technical field
The present invention relates to foodstuff drying device, be specifically related to ventilation mesh plate of grain dryer.
Background technology
There are numerous big-and-middle-sized farm and big farming household in China, and large quantities of grains of results must store by dry warehouse-in.The key of grain security storage is to reduce the water content in the grain, the generation of going mouldy with minimizing.Present stage, some grain depots of China and grain processing plant change to the drying mechanization technology mode from the conventional artificial airing the drying deposit of grain.The outstanding advantage of drying mechanization technology mode is the restriction that does not receive natural conditions, but all weather operations so be popular, are used more and more widely.The baking room of dryer; Be provided with from bottom to top hot-air channel and food passageway from top to bottom; Be provided with the ventilation orifice plate that is installed on the keel frame between hot-air channel and the food passageway, hot blast gets into food passageway through the ventilation orifice plate, and the moisture of food passageway also gets into hot-air channel through the ventilation orifice plate; Through the damp and hot exchange that constantly circulates, thereby reach the drying grain purpose.This shows that the ventilation orifice plate is the important component of oven dry machine room.At present; Oven dry machine room air vent plate is that punching completes on galvanized sheet; The blocked up punching of galvanized sheet is difficult for, and crosses to be easy to when approaching punching damage, and the aperture of punching not only must be less than the particle footpath of baking grain; And will keep certain uniformity and meet certain density specification, and the ventilation orifice plate of zinc-plated punching structure is difficult to reach these requirements.Think that in the industry the zinc-plated ventilation orifice plate of drying the machine room use now is not ideal enough, haves much room for improvement.
Summary of the invention
The present invention proposes a kind of ventilation mesh plate of grain dryer; Purpose is under the prerequisite of the aperture that guarantees eyelet less than baking grain footpath; Satisfy the perforation density of ventilation orifice plate and the uniformity that eyelet distributes,, accelerate the grain heat-drying process to improve the damp and hot exchange rate of oven dry machine room.
Technical solution of the present invention is following:
The alleged ventilation mesh plate of the present invention is the plate body that is formed by the wire woollen yarn knitting, and its woollen yarn knitting hole is a mesh.The wire woollen yarn knitting is the longitude and latitude woollen yarn knitting, and the warp-wise wire of longitude and latitude woollen yarn knitting is a raw silk rings; Around bent silk, another root is raw silk rings in the shape of a spiral for one in broadwise wire; The warp-wise raw silk rings is through the broadwise spiral side by side between two adjacent spiral coils of bent silk; Warp-wise metal raw silk rings and broadwise metal raw silk rings are the cross woollen yarn knitting.
Beneficial effect of the present invention:
(1) ventilation mesh plate of the present invention is formed by the wire woollen yarn knitting; Be mesh between silk and the silk, mesh is less relatively, and density is very big; And for being evenly distributed in all directions; Meet the requirement of damp and hot exchange between oven dry machine room hot-air channel and the food passageway fully, compared with prior art improved the rate of heat exchange of oven dry machine room effectively, accelerated grain heat-drying speed;
(2) the present invention is easy to standardization and makes moulding, long service life.
Description of drawings
Accompanying drawing 1 is a structural representation of the present invention;
Accompanying drawing 2 is a local user mode sketch map of the present invention.
The specific embodiment
It is as shown in Figure 1,
The present invention is the plate body that is formed by wire longitude and latitude woollen yarn knitting, and its warp-wise wire 11 is a raw silk rings; Around bent silk 21, another root is raw silk rings 22 in the shape of a spiral for one in broadwise wire; Its woollen yarn knitting hole is a mesh 3.The warp-wise raw silk rings is through the broadwise spiral side by side between two adjacent spiral coils of bent silk 21; Broadwise raw silk rings 22 is through the spiral that is all delegation in all spiral coils of bent silk 21, and warp-wise metal raw silk rings 11 is knitted for cross with broadwise metal raw silk rings 21.
It is as shown in Figure 2,
Of the present invention have a polylith ventilation mesh plate 1, be installed on the keel frame 4, and the combination of keel frame be arranged at oven dry machine room hot-air channel 5 and food passageway 6 between (illustrate among the figure: before 5 ventilation mesh plates 1 of hot-air channel, 6 ventilation mesh plates of food passageway, 1 back).The warp-wise silk of ventilation mesh plate is consistent with said channel direction, and the broadwise silk is vertical with channel direction.
To sum up,, good practicability is arranged, be very suitable in grain system oven dry machine room, applying though the present invention is simple.
Claims (2)
1. ventilation mesh plate of grain dryer, be arranged on oven dry machine room hot-air channel and food passageway between the keel frame on, it is characterized in that: this ventilation mesh plate is the plate body that is formed by the wire woollen yarn knitting, its woollen yarn knitting hole is a mesh; Said wire woollen yarn knitting is the longitude and latitude woollen yarn knitting, and the warp-wise wire of longitude and latitude woollen yarn knitting is a raw silk rings; Around bent silk, another root is raw silk rings in the shape of a spiral for one in broadwise wire; The warp-wise raw silk rings is through the broadwise spiral side by side between two adjacent spiral coils of bent silk; Warp-wise metal raw silk rings and broadwise metal raw silk rings are the cross woollen yarn knitting.
