- Silo has a cylinder type of structure. The silo commonly stores grains and powder during a short period or a long period. The silo is the component of process system of various industrial plants and usually installs in sequent industrial plants. In Korea, production and development of silo has increased rapidly as a logistics system project by loading transportation of bulk size. Especially, because of development of transportation system, producing massive size bulk silos have been promoted enlargement. Generally, powders such as coal powder, cement or grains are stored in the bulk storage.
- It is able to set up the silo from one set to a number of sets which is connected each other according to design.
- Wonjin Tech is able to manufacture various storage capacity of silos from several hundred to several ten thousand tons.
- Wonjin Tech is able to manufacture various silos by using different materials such as steel, stainless or cement based on a sort of stored raw materials or external environment.
Pros and cons
- It is cheap to produce and install storage volume per unit.
- It save personnel expenses because of automation about input and output transport process of raw materials.
- Storage capacity is high per using area.
- Sometimes, stagnation phenomenon is occurred in the cylinder because bridge phenomenon happens in outlet area.
- Grains and powder are located in the grain silo tend to be damaged if inner air does not circulate well.
- While reforming the structure of silo, explosion hazard is existed because of remained particles or inflammability gas in the cylinder.
Double flab damper
- Double flap damper is attached at the underbody of a collector or a silo and discharge raw materials to collecting facilities or storage tanks.
- It is able to use a substitute of a rotary valve.
- The flap damper is able to produce three types, air cylinder type, motor &weight type and oil cylinder type based on using condition.
- Damper’s flange produces a round type or a square type.
- A material of damper which we produce is decided based on operating condition and specifications of input sources (stainless, steel and so on).
Pros and cons
- Because of double gate closed type, the damper prevent dust to flow backward.
- Because the damper consists a separated structure each parts, it is able to change only the faulty parts.
- The damper is possible to control volume of discharge per minute.
- Dump valve is the product to change directions of raw material in the pneumatic conveying system line, and the product is usually installed on the silos or hoppers. 덤Dump valve is different from common turnabout valves. The Dump valve is able to transport material to the silos or hoppers through up-and-down operation of air cylinder. In addition, dump valve is able to store material evenly in each silo.
Product Features & Pros
- The valve is installed on the silos which are arranged in series or parallel, so the valve is able to transfer raw materials to the selected silos.
- It is able to design or manufacture according to buyer’s demand and mechanical composition of the valve is simple.
- Because high efficiency sealed equipment consists of a dump valve, scattering raw material is very few.
- The valve is suitable to change directions of abrasive raw material.
- There is limitation to apply a number of facilities. (It can use only storages such as silo and hopper)
- It is difficult to maintain the facility.
- Special type of belts are installed in the facility, so the belt is expensive than other common belts.
- Rotary valve usually uses to feed and expel powder of required amount and transport air.
- The rotary valve is required to its safety, ruggedness and compact structure to prevent powder’s diffusion. Technology of Wonjin tech, Co., Ltd is able to produce standard type and airlock valve (clearance less than 0.2mm) based accurate and elaborate processing technique and accurate assembling technique.
- Rotary valve is usually used to discharge materials from silos for the storage and underbody of collector. In addition, it is installed to prevent.
Slide & Knife gate valve
- Slide gate valve is attached at the underbody of storing containers, conveyor or silo and so on. The slide gate valve blocks or pass powders to the transport pipes through closing moving blade. The valve helps inspectors to monitor equipment which break out because of preventing to transfer raw materials.
- There are two types, round and square type.
- It is able to choose different materials to manufacture the valve based on entering powders. (Stainless, steel and so on).
- We are able to produce a number of different types of the valve such as manual, rack & pinion gear, reducer and slider type. Moreover, we can manufacture valve based on mechanical specifications and required type from customers.
Pros and Cons
- It is easy to install and adjust of the valve’s height.
- The valve requires low electric powder a little for operating.
- It does not leak at the seat side.
- It is difficult to control rate of discharge.
