Water circulation U-shaped screw conveyor

The water circulation U-shaped screw conveyor is a special screw conveyor. The water circulation has a cooling effect on the material. Cold water circulates continuously in the U-shaped trough, and the high-temperature material has a cooling function during the conveying process. It is mainly used to convey small granular, powdery, and small block materials, but it is not suitable for conveying materials that are easy to deteriorate, sticky, easy to agglomerate, and have a large water content.

The working principle of the water circulation U-shaped screw conveyor is similar to that of the ordinary screw conveyor. The high-temperature material is pushed forward by the rotation of the screw. The material enters the conveying trough of the U-shaped auger screw conveyor from the feed port. When the screw starts to rotate, the material moves along the conveying trough with the rotation of the screw, and the cooled material is discharged through the discharge port, which can be directly conveyed to the next processing stage or storage equipment.

Compared with other types of screw conveyors, the U-shaped screw conveyor has some unique advantages in design. First, its head and tail bearings are moved outside the shell, and the hanging bearing adopts a sliding bearing with a dustproof sealing device, which improves the reliability and service life of the equipment. Secondly, the suspension shaft and the screw shaft are connected by a slider, which makes maintenance more convenient. These designs make the U-shaped screw conveyor extremely convenient in installation and maintenance, and also improve work efficiency.

What is water circulation U-shaped screw conveyorr theory?

1. Spiral blade drive: The motor drives the spiral shaft to rotate, and the spiral blade rotates accordingly.

2. Material conveying: The material enters the U-shaped groove from the feed port, and the spiral blade pushes the material forward.

3. Water circulation cooling: The water circulating in the groove cools the material to prevent the material from overheating.

4. Material cleaning: The water circulation takes away impurities on the surface of the material and plays a cleaning role.

Structure of water circulation U-shaped screw conveyor

1. U-shaped trough: It has a U-shaped structure, contains materials, and guides the materials to move forward along the spiral blades. The material is usually stainless steel or wear-resistant material.

2. Spiral blade: It is installed on the spiral shaft and maintains a certain gap with the inner wall of the U-shaped trough. The blade can be customized according to the characteristics of the material, such as solid blades, belt blades, etc.

3. Spiral shaft: It is connected to the motor to drive the spiral blade to rotate. The material is usually carbon steel or stainless steel, with sufficient strength and rigidity.

4. Drive device: It is usually a motor to provide power for the spiral shaft. The frequency converter can be optionally equipped to achieve stepless speed regulation.

5. Bearing: Support the spiral shaft, reduce friction, and ensure the smooth operation of the equipment.

6. Sealing device: Prevent material leakage and ensure the cleanliness of the working environment.

Water circulation system: It includes water pumps, pipes, nozzles, etc., to provide circulating water in the U-shaped trough to achieve cooling and cleaning of materials.

What is the main disadvantage of water circulation U-shaped screw conveyor?

Complex structure: Water circulation U-shaped screw conveyor adds a water circulation system, which is more complex in structure and has a higher manufacturing cost.

Difficult to maintain: Due to the complex structure and the need to regularly clean and maintain the water circulation system, the maintenance difficulty is relatively large.

High energy consumption: The operation of the water pump requires additional energy, which increases the energy consumption of the equipment.

Materials are susceptible to contamination: If the circulating water is not treated or treated improperly, it may cause secondary contamination to the material.

Application of Water Circulation U-Shaped Screw Conveyor

Water circulation U-shaped screw conveyor is widely used in many industries. For example, in the cement industry, it is used to transport cement raw materials, intermediate products and finished products; in the chemical industry, it is used to transport solid raw materials and semi-finished products; in the mining industry, it is used to transport ores, concentrates and tailings. In addition, high-temperature screw conveyors are also used for slag removal in high-temperature incinerators and the transportation of carbon black powder.
