Introduction and use of new type screw conveyor
U-shaped screw conveyors have been widely used in various sectors of the national economy, such as building materials, metallurgy, chemical industry, electric power, coal, machinery, light industry, grain and food industries, suitable for conveying powdery, granular and small block materials, such as Cement, pulverized coal, grain, fertilizer, ash, sand, coke, etc., are not suitable for conveying materials that are easily deteriorated, viscous, and easy to agglomerate. The working environment temperature of LS screw conveyor is usually -20~40℃.
The temperature is generally
-20~80℃, LS screw conveyor is suitable for horizontal and small inclination arrangement, and the inclination angle should not exceed 15°. If the inclination angle is too large, please use GX series screw conveyor, or contact our company's technical department for individual design.
Features
Large carrying capacity, safe and reliable.
Strong adaptability, convenient installation and maintenance, and long service life.
The whole machine is small in size and high in rotation speed to ensure fast and even delivery.
Good sealing, the shell is made of seamless steel pipe, and the ends are connected with each other by flanges, which has good rigidity.
U-shaped screw conveyor is a kind of continuous conveying equipment widely used in metallurgy, building materials, chemical industry, grain and mechanical processing departments.
From the perspective of the displacement direction of the conveyed materials, the screw conveyors are divided into two types: horizontal screw conveyors and vertical screw conveyors. Conveying and vertical lifting, the machine is not suitable for conveying materials that are easily deteriorated, viscous, easy to agglomerate or high temperature, fear of pressure, and more corrosive.
The U-shaped screw conveyor is equivalent to ISO1050-75 standard, and its design and manufacture conform to the professional standard of ZBJ81005.1~2-88LS screw conveyor. The diameter ranges from 100mm to 1250mm, with a total of 12 specifications, which are divided into two types: single-drive and double-drive. The maximum length of the single-drive screw conveyor can reach 40m (extra-large
30m), the double-drive screw machine adopts the intermediate break shaft structure, and the maximum length can reach
80m (extra-large 60m), the length of the screw machine is every 0.5m, and it can be selected according to the needs. The head bearing and tail bearing of the screw machine are placed outside the shell to reduce the intrusion of dust into the bearing chamber and improve the reliability of the key parts of the screw machine. service life. The intermediate hanging bearing adopts two structures of rolling and sliding interchangeable, with low resistance, strong sealing and good wear resistance. The bearing bush of the sliding bearing is supplied by various materials such as powder metallurgy, nylon and babbitt alloy, which can be selected by users according to different occasions. An oil cup is installed on the outside of the hanging bearing machine, which is convenient for centralized oiling and lubrication. The position of the feeding port is flexible, and an electric discharge port is added to facilitate automatic control. It can also be equipped with a speed measurement alarm device according to user requirements.
