What is a DN500 star unloader? How much is the price of the unloader?

DN500 star unloadermainly used for dust removal equipment, dust discharge, air supply and other equipment feeding process.，it is usually composed of motor and transmission device, sealing element, impeller, rotor and shell and main valve (including shell, end cover, impeller, sealing structure, etc.)，the product looks atmospheric.，is a kind of high quality and low price DN500 star unloader，in the course of work,The motor reducer drives the impeller to rotate in the cylindrical casing. Materials fall from the upper hopper and are filled in the spaces between the impellers. With the rotation of the impellers, the materials are transported to the lower part and discharged. At the same time, the exhaust port exhausts the high-pressure gas generated by the rotation of the impeller, which reduces the phenomenon of gas ejection and ensures the continuity and stability of material transportation.。

1、Brief introduction of DN500 star unloader

DN500 star unloaderis widely used in powder engineering, pneumatic conveying and dust removal system.，structure mainly includes: equalizing exhaust port, motor reducing gear, vent, equalizing exhaust port, sealing element and so on，This DN500 star unloaderThe structural design is simple, novel and special.，it can be used in metallurgy, chemical industry, chemical raw material, building materials cement, mine and other industries。

2、DN500 star unloader structure composition

The DN500 star unloader structure is introduced as follows:

1. sealing element

Seals are used to ensure the sealing performance of the DN500 star unloader in the working process and prevent material leakage and gas backflow. High-quality seals can improve the working efficiency and service life of equipment.

2. Equalizing exhaust port

The side of the DN500 star unloader 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.

3. Rotor and shell

The rotor is the core component of the DN500 star unloader, 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. Motor and transmission device

The motor provides power for the DN500 star unloader, 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.

5. impeller

Impeller is the key part of the DN500 star unloader 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、DN500 star unloader performance advantage

DN500 star unloaders have the following advantages.

1. Strong overload capacity

Low impact inertia force, suitable for frequent starting and reverse rotation.

2. Easy maintenance

The structural design of the DN500 star unloader makes its maintenance relatively simple, and it is easy to carry out daily inspection and troubleshooting.

3. Multi-material handling

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

4. overpower protection

Some DN500 star unloaders also have overload protection function, which can automatically stop protection in case of abnormal situation to avoid equipment damage.

5. Flexible configuration

According to users' needs, special motors, such as explosion-proof, frequency modulation, speed regulation and marine motors, are configured to meet users' special requirements. The material of blades can also be specially processed according to the needs of users, such as high temperature resistance, corrosion resistance, stainless steel, flexible blades, explosion-proof impellers and so on.

DN500 star unloaderat the start of the operation,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 DN500 star unloader 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.，The overall structural design is relatively simple and compact.，it mainly includes rotor and shell, impeller, protective devices (such as sprockets, sprocket covers, etc.), main valve (including shell, end cover, impeller, sealing structure, etc.) and motor and transmission device。
