Square mouth unloader

Square mouth unloaders are divided into three categories: ordinary type, pressure resistant type, and type.

Pressure resistant type: It adopts a closed rotor and can be widely used in suction, pressure air flow conveying systems and negative pressure conveying equipment. It can transport pipeline air flow pressure without leakage, and can transport and collect materials. In this regard, it is called a Wanlock gas machine, which can not only withstand pressure, but also has ordinary functions

Type: Due to the influence of temperature on the expansion of the body, it is not conducive to the bearing and oil seal system, so it varies according to the temperature rise of material conveying and discharge port.

Ordinary type: can be used for ordinary materials below 80 degrees Celsius and at room temperature. Star shaped unloader; It can enter the feeding pipeline continuously and uniformly, and can also be used as a system and separation dust removal part discharge machine

The scope of use and advantages of star shaped unloaders:

The star shaped unloader device is the main equipment for feeding dust and air supply in dust removal equipment. The star shaped unloader is suitable for powder and granular materials. Widely used in industrial sectors such as environmental protection, metallurgy, chemical industry, grain, and food.

Star shaped unloaders (also known as rigid wheel unloaders, star shaped unloaders, shut-off fans, rotary feeders, etc.) are widely used in departments such as building materials, metallurgy, chemical engineering, and power. As various dust removal equipment, the ash hopper unloading device relies on the gravity of materials and the forced action of the feeder working mechanism to unload materials from the warehouse and feed them continuously and evenly into the next device. It can also be used as a discharge device for various equipment such as mills, dryers, and silos, suitable for dry powder and small particle materials.

The unloading device is divided into three parts: motor, cycloidal pinwheel reducer, and rotary ash discharge valve.

(1) Adopting the principle of planetary rotation, the input and output shafts are on the same axis and directly connected to the motor. The structure is compact, the appearance is beautiful and novel, the volume is small, and the weight is light.

(2) Excellent sealing performance, uniform and stable feeding, smooth unloading operation, low noise, few faults, long service life, and good performance.

(3) Stay away from bearings, gearboxes, and valve bodies to avoid the influence of high-temperature dust. The front and rear end caps have good sealing performance to prevent dust leakage and extend the service life of motor components and lubrication systems.

(4) Overload, low inertia, suitable for frequent start-up and reverse rotation.

(5) Configure motors according to user needs, such as frequency adjustment, speed adjustment, marine motors, etc. To meet the requirements of users. Materials can also be processed according to user needs, such as stainless steel, flexible blades, impellers, etc.

Precautions for using a star shaped unloader:

1. Before using the star shaped unloader, check the quantity and type of lubricating oil in the reducer, replace it with new oil after one month of operation, and replace it once a year.

2. Connect the air source interface, check if the interface is blocked by foreign objects, and if the interface is clean;

3. Before using the star shaped unloader, please confirm that the rotation direction of the rotor is clockwise (extending from the reducer to the shaft end, 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, and regularly check it during operation; At the same time, apply appropriate lubricating grease on the chain and sprocket;

5. During the whole use of the unloader, adjust the pressure reducing valve so that the sealing pressure is 0.05MPa higher than the material pressure in the valve body, and the gas is oil-free, dry compressed air;

6. The gas source at the sealed area always exists throughout the entire use of the star shaped unloader, and can only be closed after confirming that the valve has stopped running.
