Abstract

The utility model provides a pressure resistance ventilating combined cage for granaries. In the utility model, a centrifugal fan is connected with a square cylindrical hollow air storage box on which the air vents are distributed uniformly. An air circulatory system composed of a combined ventilating pipeline and a ventilating pipeline which is erected at a wall corner is connected with the air storage box, and thus the air changing circulation inside the granary is realized. The temperature difference between the temperature in the grain stack of the granary and the surface temperature of the grain stack is lower than two DEG C, solving essentially the problems of the ventilation, the cooling and the humidity dissipation of the granary and preventing the granary from breaking down. The utility model is a simple ventilating apparatus which saves labor and materials and performs critical functions on prolonging the storage time of grain and delaying the aging time of grain.

Description

Pressure resistance ventilating combined cage for granary

The utility model grain depot resistance to compression combined ventilating cage is simple about a kind of equipment, easy to use, for improving the ventilation of grain heap, cooling, the diffusing wet combined type ventilation equipment in the grain depot.

In grain depot, grain the easiest humidity of heap and intensification are the middle bottoms in the grain heap, and the facility of the ventilation of existing grain depot, cooling all is the ventilating system of simple air-introduced machine (centrifugal blower) and silo wall air inducing window and cement trench composition, can't play uniform heat radiation, cooling, damp proof effect to the heap of the grain in silo inside, when grain heap internal temperature raises and during greater than 10 ℃ of grain heap surface temperatures, must turn over the storehouse to warehouse grain heap and handle.

Task of the present utility model provides and a kind ofly can produce heat radiation, cooling effect to grain heap surface, can solve the inner ventilation uniformly of grain heap, heat radiation, cooling, damp proof effect again, make grain heap internal temperature and grain in the warehouse pile the surface temperature difference less than 2 ℃, with the draught effect of the solution grain depot that reaches internal, avoid turning over the storehouse, use manpower and material resources sparingly, particularly prolong shelf time, delay the grain ageing time to play critical effect grain.

The utility model is achieved in that the ventilative pipeline of the combined ventilating of laying several air receivers and connect air receiver on the ground of silo, form combined type ventilation cage, parallel in length and breadth being distributed on the floor level, warehouse, ventilation duct by the air receiver other end connects the outer centrifugal blower of warehouse wall, simultaneously, the ventilated pipe that is higher than 2～4 settings of grain heap maximum height in place, corner, warehouse independent distribution.When the heap of the grain in the silo heats up or is moist, start centrifugal blower, by ventilation duct, air receiver, damp-heat air is piled inner sucking-off from grain; And fresh dry and cold air enters the ventilated pipeline that is erected in the corner through the warehouse blind window, enters grain heap, forms air circulation, reach damp proof, the cooling of grain heap and ventilate, dry effect.

The square cylinder of sky in air receiver is shaped as, the ventilative pipe joint of connected combined ventilating (cross sectional shape and size and ventilated pipeline match) of 8～15 centimeter length is all drawn in three sides of cylinder, a circular ventilation duct that can connect centrifugal blower is drawn in the another one side of cylinder, and this side is near the silo wall.0.1～0.2 centimetre of air receiver wall thickness, be anti-resistance to compression, in steel framework is arranged, 40～50 centimetres of the air receiver length of sides, high 75～90 centimetres, it is closed that the bottom reaches by the wall side, air receiver end face and other three sides are evenly distributed with strip aperture (air-vent), and long 1.2～1.4 centimetres of air-vent is wide 0.08～0.12 centimetre, width keeps preventing that grain from slipping into air receiver and being advisable that air-vent density helps and the grain exchange of air.

Long 100～200 centimetres of the every joint of the ventilative pipeline of combined ventilating, 0.1～0.2 centimetre of thickness of pipe wall, the surface is the distribution air-vent evenly, cross sectional shape is circle or equilateral triangle in order to grain heap internal aspects exchange of air, and two edge connectors respectively have resistance to compression feet above ground level 6～8 centimetres, and the joint cross section is widened 2～3 centimetres, and six the strip combination screw holes that evenly distribute, long 2 centimetres of screw hole, wide 1 centimetre, use in order to combination.

Vertically the ventilated pipe joint of the threeway of " T " font and vertical " ten " font four-way is drawn long 16.5 centimetres ventilated pipe joint respectively on the centre position of long 33 centimetres ventilated pipeline, its shape and cross section are identical with the ventilative pipeline of tube wall surface and combined ventilating, in order to connecting in length and breadth and exchange of air.

Cauda, cauda are shaped as circle or equilateral triangle, six combination strip screw holes of edge distribution, and size is coincide with combined ventilating tube section joint.The even distribution air-vent in the surface of sky in the enclosed ventilation pipeline.

Design of the present utility model is installed 30～60 meters long ventilated pipeline by 500 ton-grain food holding capacity of bin warehouse; Transverse and longitudinal arrangement pitch width is 3～13 meters, and 1～2 of air receiver is installed, and place, corner, warehouse erects 2～4 combined ventilating permeability cells, and length exceeds 20～50 centimetres of maximum grain stack heights.
