Abstract
Description
Technical Field
[0001] This utility model relates to the field of dryer auxiliary support technology, specifically to a support component for a tube bundle steam dryer. Background Technology
[0002] Tube bundle steam dryers are mostly used in coal chemical plants to pre-dry coal powder, remove some of the moisture from the coal powder, and allow the coal powder to reach a certain degree of dryness before being fed into the next process for gasification.
[0003] The existing dryer installation method only uses the front and rear bearing housings as supports for the dryer's drive and transmission shafts. The dryer's own weight, plus the vibration caused by the rotation of other equipment in the same group, leads to problems such as uneven weight distribution in the dryer cylinder, increased current, large gear vibration, broken reducer foundation bolts, and cracks caused by the failure of the steam inlet and outlet journals to reach the expected fatigue value. Therefore, a tube bundle steam dryer support component is proposed. By adding a support structure under the main body, it assists in supporting the bottom of the main body and rolls with it during rotation to achieve a uniform center of gravity, thus solving the deformation and uneven weight distribution caused by the cylinder's own weight. Utility Model Content
[0004] To address the problems in the existing technology, this utility model provides a support component for a tube bundle steam dryer. By adding a support structure below the main body, it assists in supporting the bottom of the main body and rolls with it when it rotates, thereby achieving a uniform center of gravity and solving the problems of deformation and uneven weight distribution caused by the weight of the cylinder.
[0005] The technical solution adopted by this utility model to solve its technical problem is a tube bundle steam dryer support component, including a cylinder, a limiting roller A and a limiting roller B. The outer sides of the cylinder are respectively fitted with auxiliary rolling ring A and auxiliary rolling ring B. The bottom sides of the auxiliary rolling ring A are provided with concave support A, and the bottom sides of the auxiliary rolling ring B are provided with concave support B.
[0006] The inner top of each concave support A is connected to a support roller A via a rotating shaft, and the inner top of each concave support B is connected to a support roller B via a rotating shaft. A limiting groove A is formed at the center of the outer periphery of each support roller A, and a limiting groove B is formed at the center of the outer periphery of each support roller B.
[0007] By adopting the above technical solution, concave support A and concave support B support support roller A and support roller B respectively. The limiting grooves A and B on the surfaces of support roller A and support roller B respectively support auxiliary roller ring A and auxiliary roller ring B. Auxiliary roller ring A and auxiliary roller ring B are respectively fixed to the outer periphery of the cylinder. When it rotates, concave support A and concave support B cooperate with support roller A and support roller B to roll accordingly, so as to achieve uniform center of gravity and solve the deformation, weight imbalance and other effects caused by the weight of the cylinder to the machine body.
[0008] Meanwhile, the notches A and B on both sides of the inner walls of the limiting grooves A and B respectively house and support the limiting rollers A and B. The limiting rollers A and B contact the sides of the auxiliary rollers A and B respectively. When the auxiliary rollers A and B rotate, the limiting rollers A and B also roll, thereby improving the smoothness of the rotation of the auxiliary rollers A and B and avoiding friction between the two sides and the inner walls of the limiting grooves A and B, which would affect the smoothness of rotation.
[0009] Specifically, the concave support A, the supporting roller A, and the limiting roller A are all provided in two sets.
[0010] By adopting the above technical solution, the support roller A is used to support the load on both sides of the bottom of the auxiliary roller ring A.
[0011] Specifically, the concave support B, the support roller B, and the limiting roller B are all provided in two sets.
[0012] By adopting the above technical solution, the support roller B is used to support the load on both sides of the bottom of the auxiliary roller ring B.
[0013] Specifically, the auxiliary rolling ring A is located in the limiting groove A on the surface of the supporting roller A, and the auxiliary rolling ring B is located in the limiting groove B on the surface of the supporting roller B.
[0014] By adopting the above technical solution, the auxiliary rolling ring A and the auxiliary rolling ring B are respectively limited by the limiting groove A and the limiting groove B.
[0015] Specifically, notches A are evenly provided on both sides of the inner wall of the limiting groove A, corresponding to the position of the auxiliary rolling ring A, around the center position. Each notch A is connected to a limiting roller A through a rotating shaft, and each limiting roller A is in contact with the side of the auxiliary rolling ring A.
[0016] By adopting the above technical solution, notch A is used to facilitate the penetration of the limiting roller A and its side contact with the auxiliary roller ring A.
[0017] Specifically, notches B are evenly provided on both sides of the inner wall of the limiting groove B, corresponding to the position of the auxiliary rolling ring B, around the center position. Each notch B is connected to a limiting roller B through a rotating shaft, and each limiting roller B is in contact with the side of the auxiliary rolling ring B.
[0018] By adopting the above technical solution, the notch B is used to facilitate the penetration of the limiting roller B and its side contact with the auxiliary roller ring B.
[0019] The beneficial effects of this utility model are:
[0020] (1) The tube bundle steam dryer support component of this utility model supports support roller A and support roller B respectively through concave support A and concave support B. The limiting grooves A and B on the surfaces of support roller A and support roller B respectively support auxiliary roller ring A and auxiliary roller ring B. Auxiliary roller ring A and auxiliary roller ring B are respectively fixed to the outer periphery of the cylinder. When it rotates, concave support A and concave support B cooperate with support roller A and support roller B to roll accordingly, so as to achieve uniform center of gravity and solve the deformation, unbalanced weight and other effects caused by the weight of the cylinder to the machine body.
[0021] (2) The tube bundle steam dryer support component of this utility model uses notches A and B on both sides of the inner wall of the limiting groove A and limiting groove B to respectively house and support the limiting roller A and limiting roller B. The limiting roller A and limiting roller B respectively contact the sides of the auxiliary rolling ring A and auxiliary rolling ring B. When the auxiliary rolling ring A and auxiliary rolling ring B rotate, the limiting roller A and limiting roller B in contact also roll, so as to improve the smoothness of the rotation of the auxiliary rolling ring A and auxiliary rolling ring B and avoid the friction between the two sides and the inner wall of the limiting groove A and limiting groove B respectively, which would affect the smoothness of rotation.
