What is a DN100 star unloader? unloader specifications, models, and parameters

DN100 star unloaderas an important bulk material conveying equipment，is a popular DN100 star unloader，Widely used inensure air tightness of the system,dust removal equipment discharges dust.,equipment feeding,material handling,blowing-in and so on，the main features are run smoothly, handsome appearance, strong overload capacity, high wear resistance and low noise，favorable price。

1、Brief introduction of DN100 star unloader

DN100 star unloaderis widely used in powder engineering, pneumatic conveying and dust removal system.，The driving device drives the rotor to rotate in the cylindrical casing, and the material falls from the upper hopper, which is filled in the spaces between the blades and discharged with the rotation of the blades to the lower part. The side of the machine 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.，multifunctional, with functions such as equipment feeding, ensure air tightness of the system, dust removal equipment discharges dust., equipment feeding and blowing-in，features include strong reliability, favorable price, reliable work, good sealing performance and easy maintenance，it is mainly composed of motor reducing gear, motor and transmission device, protective devices (such as sprockets, sprocket covers, etc.), motor and transmission device and main valve (including shell, end cover, impeller, sealing structure, etc.)，This productThe overall structural design is relatively simple and compact.。

2、DN100 star unloader principle

DN100 star unloaderin 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.，it is an ideal choice for customers to buy DN100 star unloader。

3、DN100 star unloader function

DN100 star unloaderit has the functions of dust removal equipment discharges dust., prevent gas or dust leakage, material handling, ensure air tightness of the system and continuously and uniformly feed or discharge.，at the start of the operation,Based on a rotor with several blades rotating in a cylindrical casing. When the rotor rotates, materials fall from the upper hopper and are filled in the spaces between the blades. With the rotation of the impeller, the material is conveyed to the lower part and discharged. At the same time, the pressure equalizing exhaust port on the side of the machine body can exhaust the high-pressure gas generated by the rotation of the impeller, so as to reduce the phenomenon of gas ejection and ensure the smooth falling of materials.，widely used in dock, mine, chemical industry, chemical raw material, metallurgy and other fields，Due to the use of high-quality materials and advanced technology, the service life of the DN100 star unloader is longer, reducing the frequency of replacement and maintenance.、With overload protection function, it can automatically stop the machine in case of abnormal situation to avoid equipment damage.、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.、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.、The structural design makes its maintenance relatively simple, and it is easy to carry out daily inspection and troubleshooting.，at runtime,The driving device drives the rotor to rotate in the cylindrical casing, and the material falls from the upper hopper, which is filled in the spaces between the blades and discharged with the rotation of the blades to the lower part. The side of the machine 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.。

4、DN100 star unloader structure

The DN100 star unloader structure is introduced as follows:

1. impeller

Impeller is the key part of the DN100 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.

2. Rotor and shell

The rotor is the core component of the DN100 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.

3. Equalizing exhaust port

The side of the DN100 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.

4. sealing element

Seals are used to ensure the sealing performance of the DN100 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.

5. Motor and transmission device

The motor provides power for the DN100 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、DN100 star unloader principle

DN100 star unloaderat work,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 DN100 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.。
