The steel structure of grain silo is the best choice for grain storage, soyabean, wheat, corn, maize etc.
The assembly silo is made of high quality hot-galvanized steel plates. These plates are connected by high-strength screw bolts. The silo plates’ thickness distribution is set according to equal strength theory which makes the silo plates bear average stress. The vertical friction is supported by the stiffeners. These stiffeners are evenly and vertically distributed in the silos. The connecting screw bolts are served with round galvanized steel washers and the connection holes are served with age-resistant and water-roof washers. The silo plates’ interval is injected by water-proof daub belts that are for aviation special purpose. The silo is assisted with flat repairing doors, outside ladder, ladder guard rings.
The silo top adopts umbrella frame and the frame material is made of C model straight carbon steel. The ceiling is made of galvanized steel tile plates. The silo top served with natural ventilation windows, manhole, ladder, safety guards.
3.Steel cone base and cement cone/flat base
a.Steel cone base: when the silo capacity is below 800ton and the diameter is below 8.5meter, its base can make into steel cone base. Steel cone base is composed of upright columns, annular girder, cone plates, tie pieces etc. the upright columns are made of national standard I-shaped steel and I-shaped steel is one of the most widely used steel types in steel structure design and manufacturing. It has good structure stability and reliability. Annular girder is shaped by channel steel and it has the function of supporting silo body, connecting columns and base plates. The cone base plates are completely precast. The connection screw bolts are GB 8.8 grade standards parts. All these make installation easy and convenient, and after installation the base is really good-looking, endurable, and reliable.
b.Cement cone/flat base: when the silo capacity is comparatively big and its diameter Is below 12m. Its base is generally made into cement cone base. Cement cone base is an inverted cone hopper cast into frame with cement and concrete. It makes unloading stuff automatically. When the silo diameter is more than 12m, because the cone base height is too big, its base generally made into half-cone base or plat base. Half-cone base can’t completely unload the stuff. Flat base silo needs to unload stuff at multi-parts or equipped with a spiral silo cleaner. Cement cone base has a mediate construction period.
The choice of base type should be accorded to the geological condition, raw material price, construction level, workers salary etc. of the customer’s location and finally choose a base type with reasonable cost performance.
Grain cleaning equipment
Compound cylinder cleaning sieve
The QLYF series cylinder compound cleaning sieve is China national patent product. It has scientific structure, new outlook, double levels; can clean all kinds of dusts at the same time.
The raw grain cleaning unit whose key equipment is compound cleaning sieve, has advanced craftwork, low investment, can efficiently clean all kinds of grain impurity, save much resources and manpower. It is your optimum choice.
Grain conveying equipment
The DTG series bucket elevator has small dimension, nice outlook, big conveying capacity, good tightness, and stable working ability. It is suitable to continuously convey grain, maize, beans and other grainy stuff which is non-corrosiveness and below 60℃. The conveying system has reasonable and reliable structure. The bucket wheels adopt encapsulation technology, have big friction coefficient. The buckets adopt high-strength plastics; have long working life and full-loading coefficient. The bucket belts adopt high-strength polyester belts; have high tensile strength, low extensibility, long working life. The elevator installed anti-reverse-rotation device. When the elevator stopped suddenly, the stuff won’t revelry drop down to the elevator bottom. The belts will not overturn due to anti-reverse-roration function; it can ensure the security of maintainers.
The TGSS series scraper conveyor is widely used in the conveying of grain and powdery stuff in cereal and oil, feedstuff, and chemistry and so on. They have such advantages as tight structure, big conveying capacity, strong loading ability, and good tightness, low energy consumption, easily maintained. The conveyors can convey horizontally or aslant below 15°. The conveyors can also realize loading and unloading stuff at different parts according to procedure distribution.
TGSS series scraper conveyor main parameters
1.Design for whole project, turkey project. Include the unloading and loading system, pre-cleaning system.Tipper platform, weigh bridge etc.
2.Design for civil construction drawing, according to customer's Geological exploration report.Include the receiving material method.
3.Transport to destination port, we have professional Logistics Department.
