Description

Technical Field

[0001] The utility model relates to the technical field of a container machine shaft seal sleeve, in particular to a matching component of a container machine shaft seal sleeve and a shaft body. Background Art

[0002] The container machine shaft seal sleeve is a special device used in mechanical equipment, mainly used for waterproofing and sealing to protect the shaft part of the mechanical equipment from erosion by liquid or gas.

[0003] The existing container machine shaft seal sleeve design generally has a significant drawback, that is, the importance of heat dissipation structure is generally ignored. Because these shaft sleeves will inevitably generate a large amount of friction heat and conduction heat under high-speed operation or long-term continuous operation, and lack an effective heat dissipation mechanism, the internal temperature of the shaft sleeve will rise sharply. This sharp rise in temperature not only accelerates the thermal aging process of the internal material of the shaft sleeve and shortens its service life, but may also cause the fitting clearance between the shaft sleeve and the shaft to change due to thermal expansion and contraction, thereby affecting the sealing effect. Therefore, we propose a container machine shaft seal sleeve. Utility Model Content

[0004] The purpose of the utility model is to provide a matching assembly of a container machine shaft sleeve and a shaft body, so as to solve the problem raised in the above background technology that due to the fact that these shaft sleeves will inevitably generate a large amount of friction heat and conduction heat under high-speed operation or long-term continuous operation, and lack of an effective heat dissipation mechanism, directly leading to a sharp rise in the temperature inside the shaft sleeve. This sharp rise in temperature not only accelerates the thermal aging process of the internal material of the shaft sleeve and shortens its service life, but may also cause changes in the matching clearance between the shaft sleeve and the shaft due to thermal expansion and contraction, thereby affecting the sealing effect.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a matching assembly of a container shaft sleeve and a shaft body, comprising a shaft body, an inner sleeve fixedly installed at the center of the shaft body surface, an outer sleeve arranged on the outside of the inner sleeve, end covers arranged on both sides of the shaft body surface, a lower thermal conductive silicone pad fixedly connected to the outer wall of the inner sleeve, an upper thermal conductive silicone pad fixedly connected to the inner wall of the outer sleeve corresponding to the upper end of the lower thermal conductive silicone pad, thermal conductive copper wires fixedly connected to the four corners of the top of the lower thermal conductive silicone pad, and a heat dissipation fin fixedly installed at the center of the outer wall of the outer sleeve.

[0006] Compared with the prior art, the beneficial effects of the utility model are:

[0007] The matching components of the container machine shaft sleeve and the shaft body achieve efficient heat conduction and heat dissipation performance through the design of the inner sleeve, outer sleeve, lower thermal conductive silicone pad, upper thermal conductive silicone pad, thermal conductive copper wire and cooling fins. The heat generated by the sleeve during the operation of the shaft body can be transferred from the lower thermal conductive silicone pad to the upper thermal conductive silicone pad through the thermal conductive copper wire, and the heat is effectively guided to the cooling fins through the outer sleeve. By increasing the heat dissipation area, the heat is quickly dissipated to the surrounding environment, thereby significantly reducing the temperature inside the sleeve, avoiding problems such as material aging, sealing failure and safety hazards caused by high temperature, and providing a strong guarantee for the long-term and stable operation of mechanical equipment.

DETAILED DESCRIPTION

[0013] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0014] See also Figure 1-4 The utility model provides a technical solution: a matching assembly of a container shaft sleeve and a shaft body, comprising a shaft body 1, an inner sleeve 2 is fixedly installed at the center of the surface of the shaft body 1, an outer sleeve 3 is sleeved on the outside of the inner sleeve 2, end covers 4 are sleeved on both sides of the surface of the shaft body 1, a lower thermal conductive silicone pad 5 is fixedly connected to the outer wall of the inner sleeve 2, an upper thermal conductive silicone pad 6 is fixedly connected to the inner wall of the outer sleeve 3 corresponding to the upper end of the lower thermal conductive silicone pad 5, thermal conductive copper wires 7 are fixedly connected to the top of the lower thermal conductive silicone pad 5 near the four corners, and a heat dissipation fin 8 is fixedly installed at the center of the outer wall of the outer sleeve 3.

[0015] The two end covers 4 are symmetrically arranged, and opposite sides of the two end covers 4 are fixedly connected to the two sides of the inner sleeve 2 and the outer sleeve 3 respectively, and the inner walls of the two end covers 4 are fixedly connected to the surface of the shaft body 1.

[0016] The number of lower thermally conductive silicone pads 5 and upper thermally conductive silicone pads 6 is several. This multi-point distribution design can more comprehensively cover the heat transfer path inside the sleeve, so that the heat is more evenly conducted to the heat dissipation structure, thereby improving the heat dissipation efficiency.

[0017] The upper end of the thermally conductive copper wire 7 is fixedly connected to the lower end of the upper thermally conductive silicone pad 6 , so that the thermally conductive copper wire 7 can directly participate in the heat conduction process and use the high thermal conductivity of copper to quickly transfer heat to the heat sink fins 8 .

[0018] A support rod 9 is fixedly connected between the inner sleeve 2 and the outer sleeve 3. A plurality of support rods 9 are provided, which not only strengthens the connection strength between the inner sleeve 2 and the outer sleeve 3, but also limits the deformation of the outer sleeve 3 to a certain extent and maintains the shape stability of the sleeve. At the same time, the provision of multiple support rods 9 makes the sleeve more uniform when bearing radial or axial loads, thereby improving the overall load-bearing capacity and service life.

[0019] First grooves 10 are provided on both sides of the inner wall of the inner sleeve 2, and first sealing rings 11 are provided on the inner walls of the two first grooves 10. The inner walls of the two first sealing rings 11 are in contact with the outer wall of the shaft body 1, so that the first sealing rings 11 can fit tightly on the outer wall of the shaft body 1, effectively preventing the medium from leaking out from the inside of the sleeve.

[0020] A second groove 12 is provided on one side of the inner wall opposite to the other end covers 4, and a second sealing ring 13 is provided inside the two second grooves 12. The inner walls of the two second sealing rings 13 are in contact with the outer wall of the shaft body 1. This double sealing structure further improves the sealing performance between the sleeve and the shaft body 1. The close contact between the second sealing ring 13 and the shaft body 1 not only prevents external impurities from entering the interior of the sleeve, but also can balance the pressure distribution inside the sleeve to a certain extent, thereby ensuring the stable operation of the sleeve under harsh working conditions.

[0021] Working principle: First, the heat on the surface of the shaft body 1 is transferred to the inner sleeve 2 in close contact with it through direct heat conduction. The lower thermally conductive silicone pad 5 fixedly installed on the outer wall of the inner sleeve 2 serves as the first layer of heat conduction medium. It utilizes its good thermal conductivity to evenly distribute the heat and initially conduct it to the upper thermally conductive silicone pad 6 in the outer sleeve 3. In this process, the thermally conductive copper wires 7 on the top of the lower thermally conductive silicone pad 5 play a key role. As efficient thermal conductors, they directly transfer heat from the lower thermally conductive silicone pad 5 to the upper thermally conductive silicone pad 6, significantly improving the efficiency of heat conduction. With the further transfer of heat, when the heat accumulation in the outer sleeve 3 reaches a certain level, the heat begins to diffuse outward through the material of the outer sleeve 3. At this time, the heat dissipation fins 8 fixedly installed in the center of the outer wall of the outer sleeve 3 play an important role. The heat dissipation fins 8 quickly dissipate heat to the surrounding environment by increasing the heat dissipation area, thereby achieving effective heat dissipation and a significant reduction in the internal temperature of the sleeve.

[0022] In summary: the matching assembly of the container machine shaft sleeve and the shaft body, through the design of the inner sleeve 2, the outer sleeve 3, the lower thermal conductive silicone pad 5, the upper thermal conductive silicone pad 6, the thermal conductive copper wire 7 and the heat dissipation fins 8, realizes efficient heat conduction and heat dissipation performance. The heat generated by the sleeve during the operation of the shaft body 1 can be transferred from the lower thermal conductive silicone pad 5 to the upper thermal conductive silicone pad 6 through the thermal conductive copper wire 7, and the heat is effectively guided to the heat dissipation fins 8 through the outer sleeve 3. By increasing the heat dissipation area, the heat is quickly dissipated to the surrounding environment, thereby significantly reducing the temperature inside the sleeve, avoiding problems such as material aging, sealing failure and safety hazards caused by high temperature, and providing a strong guarantee for the long-term stable operation of mechanical equipment.
