What is a Grey cast iron star discharger? Introduction to the advantages, characteristics, and principles of the unloader

Grey cast iron star dischargeris the main equipment for conveying bulk materials.，It has the functions of dust removal equipment discharges dust., blowing-in, ensure air tightness of the system, equipment feeding and material handling，it is an ideal choice for customers to buy Grey cast iron star discharger。

1、Brief introduction of Grey cast iron star discharger

Grey cast iron star dischargeris an efficient, stable and reliable material conveying equipment.，The overall structural design is simple and novel.，it is mainly composed of main valve (including shell, end cover, impeller, sealing structure, etc.), motor reducing gear, vent, sealing element and sealing element，low noise,reliable work,compact structure,good sealing performance,easy maintenance，the advantage is The bearing and gear box are far away from the valve body to avoid the influence of high temperature dust. At the same time, the front and rear end covers have good sealing performance, which effectively prevents dust from leaking out and prolongs the service life of moving parts and lubrication systems.、Due to the use of high-quality materials and advanced technology, the service life of the Grey cast iron star discharger is longer, reducing the frequency of replacement and maintenance.、The transmission is stable and the noise is low, which provides good conditions for working environment.、Using the principle of planetary rotation, the input and output shafts are on the same axis, which has compact structure, small volume and light weight.、Can evenly and continuously feed materials into the clinker pipe to ensure the stability and continuity of material transportation.，can be customized according to user's needs.。

2、Structural characteristics of Grey cast iron star discharger

The Grey cast iron star discharger has the following structure

1. Motor and transmission device

The motor provides power for the Grey cast iron star discharger, and the power is transmitted to the impeller through transmission devices (such as gears and sprockets) to make it rotate. The transmission device shall be designed to ensure smooth and reliable power transmission.

2. impeller

Impeller is the key part of the Grey cast iron star discharger to realize material transportation. Its structural design is reasonable, which can ensure the uniform distribution of materials in the spaces between the impellers and be transported smoothly with the rotation of the impellers.

3. Rotor and shell

The rotor is the core component of the Grey cast iron star discharger, and usually consists of several blades, which rotate in the cylindrical casing. Materials fall from the upper hopper and are filled in the spaces between the blades. With the rotation of the impeller, they are transported to the lower part and discharged from the shell to protect the internal mechanism and seal, and prevent the leakage of materials and the entry of external impurities.

4. Equalizing exhaust port

The side of the Grey cast iron star discharger body is provided with a pressure equalizing exhaust port, which can exhaust the high-pressure gas brought by the rotation of the impeller, reduce the phenomenon of gas ejection, and facilitate the smooth falling of materials.

5. sealing element

Seals are used to ensure the sealing performance of the Grey cast iron star discharger in the working process and prevent material leakage and gas backflow. High-quality seals can improve the working efficiency and service life of equipment.

5、Grey cast iron star discharger performance advantage

Grey cast iron star dischargers have the following advantages.

1. Smooth operation and low noise.

Uniform and stable feeding process, stable discharging operation, low noise, few faults and long service life.

2. Multi-material handling

It is suitable for conveying powdery and granular materials and can meet the processing requirements of different materials.

3. overpower protection

Some Grey cast iron star dischargers also have overload protection function, which can automatically stop protection in case of abnormal situation to avoid equipment damage.

4. High wear resistance

It is suitable for hard and abrasive powder, and the replaceable bushing is arranged in the casing to improve the service life and facilitate maintenance and replacement.

5. Easy maintenance

The structural design of the Grey cast iron star discharger makes its maintenance relatively simple, and it is easy to carry out daily inspection and troubleshooting.

6、Grey cast iron star discharger principle

Grey cast iron star dischargerthe principle is simple.Through the rotation of the rotor with several blades in the cylindrical casing, the materials are uniformly and continuously transported from the upper hopper to the lower part to realize the function of feeding or discharging. In the pneumatic conveying system, the Grey cast iron star discharger is one of the key components, which can supply materials evenly into the clinker pipe. At the same time, in the separation and dust collection part of the system, it also has the functions of unloader and air lock.，is a device for discharging materials, which discharges materials from containers by specific mechanical or pneumatic means.。
