shanghaiImpeller feeder

Jiangsu Huaqi Electric Co., Ltd. (formerly Jiangsu Ramsey Electric Technology Co., Ltd.) specializes in the production  supply of various feeders such as impeller feeders, star-shaped ash discharge valves, star-shaped unloaders, rotary feeders, etc. Processing  customization of drawings  samples, quality assurance, welcome to consult  negotiate.

System Overview

The star-shaped discharger is used to install at the discharge port of the discharger working under negative pressure. The upper part accepts the material discharged  the discharger. The rotating impeller plays the role of conveying the material  bears the role of sealing to prevent During the pneumatic conveying process, air is sucked  the discharge port to ensure the normal discharge of the discharger. As a special discharge equipment, it plays a great role in cleaning  cleaning work.

The impeller feeder is widely used in construction materials, metallurgy, chemical industry, electric power  other industries. It can also continuously  uniformly transport the dry powder  small particles in the upper silo to the lower connection equipment for drying the upper silo. Powdery materials  small particles are continuously  evenly fed to the next equipment, which is a kind of quantitative feeding equipment.

working principle

1. The star-shaped discharger is commonly used in pneumatic output systems. For the pressure output system  negative pressure output system, the star-shaped discharger can evenly  continuously feed the feed pipe. In order to ensure that the gas  solids in the pneumatic output pipe are relatively stable, the pneumatic conveying can work normally,  at the same time, the upper  lower air pressure of the discharger can be blocked to play the role of air lock. Therefore, star-shaped unloader is an important component commonly used in pneumatic conveying system.

2. When the material in the upper silo falls under its own weight to fill the gap between the blades, it is discharged in the lower part as the blades rotate. Therefore, the star-shaped unloader can unload quantitatively  continuously.

3. The star-shaped unloader can be used in the material collection system as the unloader of the silo. The star-shaped unloader is currently the most advanced unloading device in China. It is commonly used in the dust removal system as one of the important equipment of the dust removal system. It is especially suitable for dust  small particle materials,  is widely used in engineering projects in environmental protection, metallurgy, chemical industry, food, cement, road construction, drying equipment  other industrial industries.

4. Temperature-resistant type The temperature of the materials it transports can reach 280°C. The bearings at both ends are isolated  the impeller to prevent the ultra-fine powder  contacting the bearings. The temperature of the high-temperature-resistant discharger can reach 500°C,  it is connected by sprockets. There is a certain distance between the reducer  the unloader housing.

The composition of the star-shaped discharger  the structure of the star-shaped discharger are usually composed of a rotor impeller with several blades, a casing, a seal, a reducer, a motor, etc. The star-shaped discharger is also called a rotary feeder. Air lock valve, star-shaped ash discharge valve, star-shaped feeder, etc.

The star-shaped unloader can be used in the material collection system as the unloader of the silo. The star-shaped unloader is currently the most advanced unloading device in China.It is commonly used in the dust removal system as one of the important equipment of the dust removal system. Especially suitable for dust, small particles of materials, environmental protection, metallurgy, chemical industry, food, cement, road construction, drying equipment  other industrial projects are preferred.

System Features

1. Compact structure, beautiful appearance, easy to use.

2. Smooth operation  low noise.

3. Due to the bearing, the gear box is at a distance  the housing,  the lubrication is greatly improved for high temperatures.

4. Can be designed  manufactured according to user requirements.

5. Before the product leaves the factory, it is filled with special grease for the pin wheel cycloid reducer, please check the oil regularly. Star feeders are commonly used in pneumatic output systems. For pressure output systems  negative pressure output systems, the star discharger supplies the feed pipe uniformly  continuously to ensure that the gas in the pneumatic output pipe  the solids are relatively stable , So that the pneumatic conveying can work normally,  at the same time, the upper  lower air pressure of the discharger can be blocked to play the role of air lock. Therefore, the star-shaped discharger is an important part commonly used in pneumatic conveying systems.

classification

The star-shaped unloader is divided into three types: ordinary type, pressure-resistant type  high temperature-resistant type.

Pressure-resistant type: It uses a closed rotor, which can be widely used in suction-type, pressure-feeding air flow transmission systems  negative pressure transmission equipment. , So it is called the Wansuo air-conditioner in this respect, which  only can withstand pressure, but also has ordinary functions.

High temperature resistance type: according to the temperature rise of the material delivery  the discharge port, because the temperature  quality have an effect on the expansion of the body,  are unfavorable to the bearing  the oil seal system.

Ordinary type: It can be used on ordinary materials below 80 degrees  normal temperature.It can continuously  evenly feed into the conveying pipe,  it can also function as a discharger in the system  the separation dust collection section.

Precautions

1. Before using the star-shaped unloader, check the amount of lubricating oil  the type of oil in the reducer, replace with new oil after one month of operation,  change the oil once a year thereafter.

2. Connect the air source interface,  check whether the interface is blocked by foreign objects, to ensure that the interface is clean  smooth;

3. Before using the star-shaped unloader, make sure that the rotation direction of the rotor is clockwise (seen  the shaft end of the reducer, which is consistent with the arrow on the sprocket cover);

4. Before using the star-shaped unloader, open the sprocket cover to check the tension of the chain. During the operation, it should be checked regularly; at the same time, apply appropriate grease to the chain  the sprocket;

5. During the entire use of the unloader, adjust the pressure reducing valve so that the pressure at the seal is greater than 0.05MPa of the material pressure in the valve body. The gas is oil-free, dry compressed air;

6. During the entire use of the star-shaped unloader, the air source at the seal always exists,  the air source can be turned off only after it is believed that the valve is out of service;

common error

1. During the transportation  installation of the star-shaped unloader, it should be kept stable to avoid collision  even cause the shell to break  deform.

2. The reducer has been filled with lubricating oil No. 0 grease before leaving the factory,  the ash discharge valve has been filled with lithium-based grease. Within 6-10 months after being put into use, the transmission  bearing parts should be supplemented  replaced with grease. If the ambient temperature is high  there is too much humidity  dust in the air, the oil change time should be shortened appropriately.

3. During use, if the equipment has air leakage  ash leakage in the axial direction, the material cover can be firmed.

4. In the process of operation, avoid equipment overload due to large material particles  strong adhesion,  equipment jam  motor short-circuit caused by foreign trade foreign objects in the dust collector, causing equipment  damage. It is recommended that users promptly check  install Overload protection device.

5. This machine is suitable for continuous working system, allowing forward  reverse operation.

6. The output shaft, input shaft  other parts of the unloader are  allowed to be hammered directly to prevent damage.
