Introduction of ground cage ventilation duct:

The ground cage ventilation duct is a mature ventilation duct product in the collection of grain storage machinery in China.The product is one of the important infrastructed infrastructure of the real-safe storage grain in the ground, and is stamped by the national standard cold rolled steel sheet. The ground cage ventilation duct is simple and practical, beautiful and generous, easy to operate, rational planning, low operating cost, anti-oxidation, anti-corrosion, anti-kneading, no leakage grain, good interchangeability, easy removal, convenient for store, long service life, free from the barn conditions, easy to spread in different regions. It can cooperate with the fan, hot air fan, warehouse external administration machine, tuning machine, and nitrogen generator, etc.Achieving a variety of technological purposes. Such as grain cooling, reduce water content, preservation, insecticide, inhibit mildew, delay aging and so on.Achieving a variety of technological purposes.

The main appliction of ground cage ventilation duct:

This ground cage ventilation duct is mostly used in the flat horizontal grain warehouse or the open-air bulk grain stack,including air distribution boxes,main air duct,branch duct,airflow regulating valve, tee,elbow,plug and other components.Can make the air evenly into the grain heap.It can be used for grain cooling, lower the moisture in grain, fumigation, air conditioning, conditioning, elimination of residual poison, odor and other operations.

The ground cage ventilation duct is suitable for reducing water content,precipitation, grain cooling, circulation fumigation and other grain storage technologies of bulk grain（corn, wheat, soybean, rice, beam, etc.）

1.This above-ground cage ventilation duct  has a long service life: the surface is specially treated, first stamped and then galvanized, with anti-oxidation and anti-PH3 corrosion performance.

2. The ground cage ventilation duct has good ventilation performance: the opening rate of the above-ground ventilation duct can reach 25%-35%, and the overall ventilation uniformity is good.

3. The ground cage ventilation duct has strong compressive performance, using Shanghai Baosteel's high-quality raw materials, excellent punching technology, no breaks and burrs, and can be used in flat warehouses, vertical silos, and squat silos.

4. The ground cage ventilation duct has strong compatibility: the product can be disassembled and combined for use according to the ventilation intention requirements, which saves time and effort. It occupies a small space and is convenient for transportation and storage.

5. The ventilation holes are fish scales or bridge ventilation holes, and the opening rate can be adjusted up to 35%.

6. The main components of the the ground cage ventilation duct are made of 1.5-2.0 mm thick high-quality hot-dip galvanized steel sheet, which is formed by CNC stamping. Uniform opening, low wind resistance and high strength.

7. The parts of the ground cage ventilation duct have reliable standards, strong interchangeability, diverse installation and combination methods, fast and reliable, good strength, can withstand the force of 10 meters high grain and the stepping pressure of people walking, without grain leakage.

8. The main accessories of the ground cage ventilation duct are all galvanized, which is beautiful and bright, with firm plating, corrosion resistance and long life.

9. It can be connected with various types of fixed and mobile circulation fumigation systems. 

1. The model of the ground cage ventilation duct : HZ-D400; HZ-D500

2. The working environment temperature of the ground cage ventilation duct : -40℃～50℃

3. The working environment humidity of the ground cage ventilation duct : 20%～99%RH

4. The handling capacity and load of the ground cage ventilation duct : it can withstand the pressure of grains stack above 6 meters in height
