Introduction to DN400 star unloader, advantages, characteristics and principles of unloader

DN400 star unloaderis the main equipment for dust removal equipment, ash discharge, air supply and other equipment feeding.，the advantage is The structural design makes its maintenance relatively simple, and it is easy to carry out daily inspection and troubleshooting.、By adopting the principle of planetary rotation, the input and output shafts are on the same axis and directly connected with the motor, which makes the whole structure compact, beautiful and novel in shape, small in volume and light in weight.、Equipped with frequency conversion governor, the rotating speed of impeller can be adjusted according to actual demand, so as to flexibly control the conveying quantity of materials.、The structure design is reasonable, which is convenient for daily maintenance and overhaul. At the same time, its good sealing performance also reduces the complexity and frequency of maintenance work.、With overload protection function, it can automatically stop the machine in case of abnormal situation to avoid equipment damage.，at work,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.，The overall structural design is relatively simple，structure mainly includes: protective devices (such as sprockets, sprocket covers, etc.), rotor and shell, sealing element, vent, protective devices (such as sprockets, sprocket covers, etc.) and so on，the product looks atmospheric.。The following is to introduce the DN400 star unloader:

1、Brief introduction of DN400 star unloader

DN400 star unloaderis an efficient and flexible material conveying equipment.，was developed and designed by hyde powder。

2、DN400 star unloader video live broadcast

The following is the live video of DN400 star unloader designed and produced by hyde for users, from which we can see the 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.、Can evenly and continuously feed materials into the clinker pipe to ensure the stability and continuity of material transportation.、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 transmission is stable and the noise is low, which provides good conditions for working environment.、By adjusting the parameters such as DN400 star unloader speed or blade angle, the conveying capacity of materials can be flexibly adjusted to meet different technological requirements. of DN400 star unloader.。

4、Structural advantages of DN400 star unloader

The DN400 star unloader has the following structure

1. Equalizing exhaust port

The side of the DN400 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.

2. Motor and transmission device

The motor provides power for the DN400 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.

3. impeller

Impeller is the key part of the DN400 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.

4. sealing element

Seals are used to ensure the sealing performance of the DN400 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. Rotor and shell

The rotor is the core component of the DN400 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.

5、Functional advantages of DN400 star unloader

DN400 star unloaders 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. Automatic locking mechanism

The DN400 star unloader has an automatic locking mechanism and the electric push rod has a two-way safety system, which makes the work reliable, stable and flexible.

3. Easy maintenance

The structural design of the DN400 star unloader makes its maintenance relatively simple, and it is easy to carry out daily inspection and troubleshooting.

4. Compact structure and beautiful appearance.

The DN400 star unloader adopts the principle of planetary rotation, and the input and output shafts are on the same axis, with compact structure, small volume and light weight.

5. Strong overload capacity

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

DN400 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 mainly composed of impeller, main valve (including shell, end cover, impeller, sealing structure, etc.), equalizing exhaust port, sealing element and motor reducing gear，This productSimple structure and reliable operation.，the product looks beautiful.。
