U-shaped screw conveyor

The shell shape of the U-shaped screw conveyor is U-shaped, and there is a U-shaped groove cover on the upper part of the shell, so it is called a U-shaped screw conveyor. According to the design form, it can be divided into closed and open types.

The U-shaped screw conveyor adopts the DIN15261-1986 process standard and is designed and manufactured in accordance with the screw conveyor standard. The overall design structure of the machine is relatively simple, consisting of components such as U-groove, feed inlet, flange, drive device, lining plate, and upper cover. Small cross-sectional area, good sealing performance of the machine body, simple equipment operation, no hidden dangers for operators, low manufacturing cost of U-shaped conveyor, and high energy consumption of the conveyor.

U-shaped screw conveyor; Mainly used for transportation, mixing, dehydration, drying, unloading and other operations. Common U-shaped specifications and models include 200, 250, 300, 400, and 500. The length of a regular U-shaped conveyor ranges from 4 meters to 50 meters. Of course, non-standard U-shaped screw conveyors can also be designed according to working conditions.

The U-shaped screw conveyor has multiple conveying modes, including horizontal conveying, inclined conveying, vertical conveying, and even various forms. The lifting bearing in the middle of the conveyor has two structures: rolling and sliding, which are interchangeable. The U-shaped screw conveyor can work in conjunction with other conveying equipment. And it can be used in conjunction with other conveying equipment or working devices. Application of screw conveyor: The screw conveyor is used in sewage treatment plants to transport materials with a net distance of 50mm, such as cleaning machine mesh residue and filter press mud cake. Good environmental performance. The spiral surface is fully enclosed, easy to clean, environmentally hygienic, and free from material contamination and leakage. High torque and low energy consumption. Due to the lack of axis in the spiral, the material is not easily blocked, and the discharge port is not blocked, allowing for low-speed operation, stable transmission, and reduced energy consumption. The torque can reach 4000n///m. Large conveying capacity.

U-shaped screw conveyor is a type of screw conveyor. Made according to DIN15261-1986 standard and designed to comply with JB/T7679-2008 screw conveyor standard. U-shaped screw conveyors are widely used in sectors such as grain, chemical, building materials, metallurgy, mining, and power, mainly for transporting small particles, powders, and small pieces of materials. Not suitable for conveying materials that are prone to deterioration, high viscosity, clumping, and high moisture content.

Classify according to the driving mode of the screw conveyor

a、 When the length of the U-shaped screw conveyor is less than 35m, the screw is driven by a single axis.

b、 When the length of the U-shaped screw conveyor is greater than 35m, the double axis drive screw is used.

Distinguish based on the type of intermediate suspension bearing of the screw conveyor

a. M1- is a rolling lifting bearing that uses 80000 sealed bearings. The shaft cover has a dust-proof sealing structure and is commonly used for not easily oiled, not oiled, or contaminated materials. It has good sealing effect, long service life of the lifting shaft, and high conveying material temperature ≤ 80 ℃.

b. M2 sliding suspension bearings are equipped with dust-proof sealing devices, including cast copper tiles, alloy cast iron tiles, and copper based graphite low oil lubricating tiles. Commonly used for conveying materials (t ≥ 80 ℃) or materials with high moisture content.

Classification of Spiral Conveyor Materials

a、 Ordinary carbon steel U-shaped screw conveyor - mainly suitable for industries with high wear and tear, such as cement, coal, stone, etc. that do not require materials.

b、 Stainless steel U-shaped screw conveyor - mainly suitable for industries such as food, chemical, and food that require a conveying environment. It has high cleanliness, pollutes materials, has a long service life, but relatively high cost.
