Nowadays, the discharger is widely used. Next, the editor will introduce the discharger in detail.
The star卸料器 is a primary equipment for dust removal systems, responsible for discharging ash, supplying air, and feeding other equipment. The star卸料器 is suitable for powdered and granular materials.
The star-type unloader is designed for installation at the discharge outlet of unloaders operating under vacuum. It receives the discharged material at the top, with the rotating blades acting as a conveying mechanism and also serving as a seal to prevent air from being吸入 during the pneumatic conveying process. As a special type of unloader, its normal discharge plays a significant role in cleaning and washing operations.
One: Star Discharger Categories: The star discharger is divided into three main types: standard, pressure-resistant, and high-temperature-resistant.
The pressure-resistant model features a sealed rotor, making it suitable for a wide range of conveying systems, including suction and pressure airflow systems, as well as negative pressure conveying equipment. It effectively maintains pressure inside the conveying tubes without leakage, enabling efficient transportation and collection of materials. Hence, it is referred to as the万能锁气机 (Universal Lock Gas). Not only is it pressure-resistant, but it also boasts the functionalities of a standard model.
High-Temperature Resistant: Due to the varying temperature rise in material conveying and at the discharge opening, the temperature quality affects the expansion of the body and is detrimental to the bearing and sealing system.
Standard Model: Suitable for materials at or below 80 degrees Celsius and ambient temperatures, it can continuously and evenly supply materials into the feeding pipe. Additionally, in the system and dust collection section, it can function as a discharger.
Two: Working Principle of the Star-type Discharger
The star-type discharge valve is commonly used in pneumatic conveying systems. For pressure or vacuum conveying systems, the star-type discharge valve can uniformly and continuously supply material to the conveying pipeline. With a stable gas-solid ratio within the pneumatic conveying pipe, it ensures normal operation of the conveying process. Additionally, it can isolate the upper and lower pressure of the discharge valve, thereby acting as a locking mechanism to prevent gas leakage. Consequently, the star-type discharge valve is an essential component frequently used in pneumatic conveying systems.
2. As the material in the upper hopper falls due to its own weight, it fills the gaps between the blades and is discharged at the bottom as the blades rotate. Therefore, the star-type unloader can discharge material in a quantitative and continuous manner.
3. The star discharge valve can be used in material collection systems as a hopper unloader. The star discharge valve is currently the domestic leader in unloading devices and is commonly used in dust removal systems as one of the key equipment. It is particularly suitable for dust and fine-grained materials, and is widely favored in engineering projects across various industries such as environmental protection, metallurgy, chemicals, grain, cement, road construction, and drying equipment.
4. The temperature-resistant model can handle material temperatures up to 280°C, featuring a certain degree of isolation between the two bearings and the impeller to prevent contact with ultra-fine powder. The high-temperature-resistant model can transport materials at temperatures up to 500°C and utilizes a sprocket connection.
III. Applications and Fault Handling
The star卸料器 is widely used in industries such as construction materials, metallurgy, chemicals, and electricity as the ash discharge device for various dust removal equipment. It relies on the gravitational force of the material and the forced action of the feeding mechanism to discharge the material from the storage bin and continuously and uniformly feed it into the next unit. It can also serve as a feeding and discharging device for various mills, dryers, silos, and other equipment, suitable for dry powdery and small granular materials.
Star-type Discharge Device Installation and Use
The star-type discharge valve should avoid overloading during operation due to large particle size and strong adhesion of materials, or equipment jamming or motor short-circuiting caused by foreign objects in the dust collector, which may lead to equipment damage. It is recommended that users promptly inspect and install overload protection devices.
During operation, if the equipment experiences issues such as air leakage along the axial direction or dust leakage, simply tighten the feed cover.
3. The machine is factory-fitted with sufficient 00 grease lubrication for the reducer, and lithium-based grease for the ash discharge valve. Within 6-10 months of operation, the transmission and bearing components should be replenished or replaced with lubricant. In high-temperature, humid, or dusty environments, the oil change interval should be appropriately shortened.
4. The star-type unloader should be handled and installed smoothly to avoid collisions, which could lead to shell fracturing and deformation.
5. When installing the discharger's output and input shafts with other parts and accessories, direct hammering is not permitted to prevent damage.
Model is suitable for continuous operation, both forward and reverse rotation are available.
