Description

Technical Field

[0001] The utility model relates to the technical field of mechanical equipment cooling, in particular to a temporary cooling device for a bearing seat. Background Art

[0002] During the operation of rotating mechanical equipment, the bearings often have high temperatures. If the temperature cannot be reduced in time, the bearings will wear more severely or even be damaged, thereby reducing the service life of the equipment. Common reasons for high bearing temperature include poor lubrication, insufficient cooling, abnormal bearings, large vibrations, etc. It is not easy to find the cause of the high bearing temperature without stopping the equipment for inspection. Even if the cause is found, it is often necessary to stop the equipment to solve it, causing losses. Therefore, there is an urgent need for a temporary cooling device suitable for the bearing seat of rotating mechanical equipment, which can effectively reduce the temperature of the bearing seat without affecting the normal operation of the equipment.

[0003] The prior art discloses a rotary kiln air cooling device (publication number: CN1004329938A), comprising a cold air jacket and a blower. The cold air jacket is provided with a cold air outlet. A cold air duct is provided on the outer cylindrical surface of the cold air jacket. The cold air duct comprises a sealed space composed of an inner arc plate, an outer arc plate, a left sealing plate, a right sealing plate and a front sealing plate. The front sealing plate is provided with a plurality of first through holes connected to the sealed space. The first through holes are connected to one end of a steel pipe. A second through hole is provided in the middle of the outer arc. The second through hole is connected to the end of an air outlet duct of the blower. The air outlet of the blower is connected to the air outlet duct through a flange, bolts and nuts. The device can be used for cooling a rotary kiln, and has the advantages of good cooling effect and no need to shut down mechanical equipment for cooling. However, there are still unresolved technical problems: first, the shape of the device is relatively fixed, and it is applicable to rotary kilns. It cannot adjust the shape and fit tightly to surfaces of other shapes that need to be cooled. Secondly, since the air outlet duct and the blower outlet are connected by bolts and nuts, it is inconvenient to disassemble and assemble, and is not conducive to replacement. Thirdly, a rigid connection is used between the air outlet duct and the blower, and cold air is easy to leak from the connection, resulting in reduced cooling efficiency and waste of energy. Utility Model Content

[0004] The utility model aims to provide a temporary cooling device for a bearing seat, so as to solve the technical problem that the bearing seat urgently needs temporary cooling.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A temporary cooling device for a bearing seat comprises a cooling belt, wherein the cooling belt comprises a heat-conducting silicone sheet and a plurality of aluminum flexible tubes, wherein the plurality of aluminum flexible tubes are arranged side by side, and the heat-conducting silicone sheet wraps the plurality of aluminum flexible tubes arranged side by side to form a flexible belt; and further comprises a cold air duct, wherein the cold air duct is connected to the cooling belt.

[0007] The principle of this scheme is:

[0008] In actual application, the cooling belt composed of the thermally conductive silicone sheet and the aluminum flexible tube is directly attached to the outer surface of the bearing seat that needs to be cooled. According to the different shapes and sizes of bearing seats, the cooling belt can be laid side by side or connected, and at the same time, it can be bent and deformed according to the required shape. The thermally conductive silicone sheet and the aluminum flexible tube quickly absorb the heat of the bearing seat, thereby effectively reducing the temperature of the bearing seat.

[0009] The advantages of this solution are:

[0010] 1. This cooling device is not affected by the shapes of various bearing seats. It can fit on the surface of the bearing seat, directly absorb the heat of the bearing seat, and quickly and effectively reduce the temperature of the bearing seat.

[0011] 2. The thermal conductive silicone sheet material is relatively soft, has good compression performance, good thermal conductivity and insulation performance, and a relatively large adjustable range of thickness. It is suitable for filling cavities. Both sides have natural stickiness, and are easy to operate and maintain. The thermal conductive silicone sheet can reduce the contact thermal resistance between the heat source surface and the contact surface of the aluminum flexible heat dissipation pipe, and can fill the gap of the contact surface well. The thermal conductive silicone sheet is reusable and easy to carry.

[0012] 3. Before the equipment is shut down for maintenance, the device can continuously cool the bearing seat and play a temporary cooling role. After the cause of the heat is eliminated, the device can be removed at any time and reused.

[0013] Preferably, as an improvement, a cold air distributor is further included, one end of which is rectangular and connected to the cooling belt; the other end is circular and connected to the cold air pipe. The rectangular end is better suited for aluminum flexible pipes arranged side by side, and the circular end is better suited for the cold air pipe. The targeted connection shape can make the contact surface of the two have better fit, ensuring that the internal air does not leak out.

[0014] Preferably, as an improvement, a limit block is provided on the inner wall of the cold air distributor to ensure that the cooling belt will not be excessively inserted into the cold air distributor.

[0015] Preferably, as an improvement, the cold air pipe is a flexible plastic pipe, which can be bent and deformed to adapt to the environment, reduce the floor space, and facilitate storage. At the same time, the flexible material has better fit with the cold air distributor, ensuring the air tightness inside the pipe.

[0016] Preferably, as an improvement, the cold air pipe is connected to a cold air source. The cold air source may be compressed air drawn from a compressed air pipeline, or cold air drawn from an air duct, or a small fan may be directly connected to one end of the cold air pipe. The cold air source continuously introduces cold air into the aluminum flexible pipe, continuously taking away the heat emitted by the bearing seat, and ensuring a good cooling effect of the entire cooling device.
