Introduction of three cylinder dryer

The three cylinder dryer is an efficient combined dryer, also known as three drum dryer and three return dryer. It is an efficient dryer with three layers of heat insulation and cyclic self insulation structure. The main advantages of the three cylinder dryer are better heat preservation and higher work efficiency than the traditional single drum dryer. It is a domestic energy-saving dryer.

Suitable materials for three cylinder dryer

Generally, the suitable materials for three cylinder dryer are river sand, sand, yellow sand, quartz sand and other materials with low viscosity and no flow. Rotary dryer is recommended for other materials.

Structure of three cylinder dryer

Three cylinder dryer is composed of three concentric circles with different diameters, which is the main body of the dryer. The main body rotates horizontally on the four supporting wheels at both ends through the tires at both ends, and the feeding end of the cylinder body is provided with a hot blast stove device. The discharge end is equipped with dust cover and automatic blanking device. The dust cover is connected with the dust remover through pipes. The dust removal equipment, feeding equipment and conveying equipment can be designed separately according to the process conditions and requirements of users.

Drying process of three cylinder dryer

The material end is fed into the inner cylinder of the dryer. The material enters into the inner cylinder through the spiral guide plate of the inner cylinder. There are many spiral lifting plates in the inner cylinder. When the material reaches the left end of the inner cylinder, it falls into the middle cylinder due to the self weight. Through the guide plate, the material is pushed back to the middle cylinder under the rotation of the cylinder. Under the action of the lifting plate of the middle cylinder, the material moves to the right until the right end of the middle cylinder, and the material is under the action of self weight Fall into the outer cylinder. In the same way, the material falls into the discharge end cylinder under the action of the outer cylinder spiral lifting plate.

In the three concentric cylinders of the main body of the dryer, there are different numbers and angles of curved spiral spiral lifting plates. The end of each cylinder body is a guide plate. The main body of the dryer drives two driving supporting wheels at both ends through two decelerating motors to rotate the belt around the center. The wet material is fed into the feeding end of the inner cylinder through the feeding device and the feeding pipe. The wet material is pushed rapidly to the spiral lifting plate through the spiral guide plate. With the rotation of the cylinder body, the spiral lifting plate set in the four cylinders causes the material to continuously roll, disperse and make longitudinal movement towards the discharge end at the same time. At the same time, the hot air from the hot blast stove enters into the inner cylinder, the middle cylinder and the outer cylinder successively to conduct strong heat exchange with the materials. As the metal steel plate conducts heat faster than the material to be dried, the steel plate and the lifting plate of the cylinder are heated first, and then the heat is transmitted to the material in the way of conduction and radiation. After the material is heated, the temperature rises. When the temperature rises to the temperature of water evaporation, water vapor is separated from the material and discharged into the atmosphere with the smoke and dust after passing through the dust collector, so as to achieve the purpose of material drying.

Advantages of three cylinder dryer

1. The three cylinder dryer adopts the European energy-saving clamp type structure. The inner cylinder, the middle cylinder and the outer cylinder have three layers of heat insulation.

2. At the same time, the drum is wrapped with thermal insulation material and stainless steel plate to further reduce heat loss and improve thermal efficiency.

3. Special thermal design concept can eliminate heat loss in wind tunnel, increase heat exchange area and evaporation intensity per unit volume, and save energy.

4. In line with the international policy of creating an environment-friendly and resource-saving society, it is an environmental protection and energy-saving product to replace the traditional drying equipment.

5. It has compact structure and less floor area, which is half of the land occupied by single drum drying with the same output.

6. It has the advantages of reliable operation, low energy consumption, high thermal efficiency and good drying of materials.

7. Easy automatic control, less operators.

Trouble shooting of three cylinder dryer

1. The moisture content of the material after drying is greater than the specified value.

The elimination method is to control the production capacity of the dryer and increase or decrease the heat supply.

2. The rolling ring has swing to the cylinder.

The reason is that the concave joint side of the rolling ring is not clamped. The elimination method is to use the backing plate to keep the rolling ring and concave joint uniform and properly clamped, so as to prevent the occurrence of over tightening.

3. The meshing clearance between the big gear and the small gear is damaged. The reason is the wear of tugboat, the wear of block wheel and the wear of pinion. The elimination method is turning or replacing according to the wear condition, and can also be installed on the opposite side or renewed in pairs.

4. The whole body vibrates. The reason is that the connection between the tugboat device and the base is damaged. The elimination method is to correct the fastening connection and make it in the correct position.

5. The side of the ring is worn. The elimination method is to turn or replace the rolling ring according to the wear degree.
