Shaftless screw conveyors are used in various industrial sectors, such as environmental protection, building materials, electric power, chemical industry, metallurgy, coal, aluminum and magnesium, machinery, light industry, grain and food industry; It is suitable for conveying powdery, granular and small materials, such as cement, cinder, grain, chemical fertilizer, ash pox, sand, sludge and other materials at a horizontal or inclination angle of less than 20 ℃, and the temperature is below 200 ℃. What are the advantages of Ruizhi brand shaftless screw conveyor produced by Anhui Mingguang Ruisheng Machinery Co., Ltd.? Today we'll learn about it.
Shaftless screw conveyor is mainly composed of driving device, head assembly, casing, shaftless screw body, groove lining plate, feed inlet, discharge outlet, machine cover (when required), base, etc.
1. Driving device: cycloidal pinwheel reducer or shaft mounted hard tooth gear reducer shall be adopted. In the design, the driving device shall be set at the end of the discharge port as far as possible to make the spiral body in the tension state during operation.
2. The head is equipped with thrust bearing, which can bear the axial force generated when conveying materials.
3. Casing: the casing is U-shaped or O-shaped, with rain proof cover on the upper part. The material is stainless steel, carbon steel or FRP, which can be selected by customers.
4. Shaftless spiral body: made of stainless steel or carbon steel.
5. Rubber or cast stone plate, etc.
6. Inlet and outlet: there are two types: square and circular. Generally, the form of inlet and outlet is determined by the user.
Compared with the traditional shaftless screw conveyor, the shaftless screw conveyor has the following outstanding advantages because it adopts the design of no central shaft and hanging bearing and uses the integral steel screw with certain flexibility to push materials:
1. The spiral has super wear resistance and durability and long service life.
2. Strong anti winding performance: no interference of central axis. It has special advantages for conveying banded and easily wound materials to prevent accidents caused by blockage.
3. Good environmental protection performance: fully enclosed conveying and easy to clean spiral surface are adopted, which can ensure environmental sanitation and the transported materials are not polluted and not easy to leak.
4. Large torque and low energy consumption: because the screw has no shaft and the materials are not easy to be blocked, it can run at a low speed, drive smoothly and reduce energy consumption.
5. Large conveying capacity: the conveying capacity is 1.5 times that of the traditional shaft conveyor with the same diameter, up to 40m3 / h. The conveying distance is long, up to 25 meters. According to the needs of users, multi-level series installation can be adopted to convey materials over a long distance.
6. The utility model has the advantages of compact structure, simple operation, economy and durability, little maintenance and low maintenance cost.
