Description

Technical Field

[0001] This utility model relates to the technical field of shaft seal cooling structure, and more specifically to a shaft seal cooling structure for an emulsifier. Background Technology

[0002] An emulsifier shaft seal is a sealing element or device installed between the shaft and the housing of an emulsifier to prevent material from leaking outwards along the axial direction, to prevent air or external contaminants from entering, and to maintain the internal pressure and vacuum conditions of the equipment.

[0003] According to patent publication number CN219082241U, published on May 26, 2023, a high-pressure resistant rotary shaft seal is disclosed, including a shaft seal seat and a shaft seal end cover. A fixing bolt, which is clearance-fitted with the shaft seal end cover, is disposed through the shaft seal end cover. The fixing bolt is threadedly connected to the shaft seal seat. A first annular groove is provided at the intersection of the end face connecting the shaft seal seat and the inner wall of the shaft seal seat. A second annular groove is provided at the intersection of the end face connecting the shaft seal end cover and the outer wall of the shaft seal end cover. A stationary ring is disposed in the first annular groove, and a moving ring is disposed in the second annular groove. The moving ring abuts against the stationary ring and the side wall of the first annular groove. The inner diameter of the moving ring is smaller than the inner diameter of the shaft seal end cover. An O-ring is fitted on the shaft seal seat. In the technology of the aforementioned patent, the use of an O-ring enhances the sealing performance between the rotary shaft seal and the equipment bore. However, in actual use, the O-ring is in contact with the rotating shaft for a long time, and the heat accumulated on the contact surface of the O-ring is difficult to dissipate under the high speed of the rotating shaft. The simple design of this structure itself is prone to causing the O-ring to age rapidly under long-term high-temperature use. Utility Model Content

[0023] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0024] like Figures 1-4 As shown, a shaft seal cooling structure for an emulsifier includes a mounting plate 1 for mounting on the top of the emulsifier body. A protruding tube 11 is mounted on the mounting plate 1, and an inner ring plate 13 is fixedly mounted on the inner wall of the protruding tube 11. A sealing ring 3 is mounted on the inner ring plate 13, and two contact portions 34 protruding towards the shaft and an extension portion 35 protruding outwards are symmetrically arranged on the inner side of the sealing ring 3. A cooling machine 4 is disposed inside the protruding tube 11, and a cooling ring channel 44 is provided on one side of the two contact portions 34 and the extension portion 35. Active, forced liquid cooling is achieved through the cooling ring channel 44 to rapidly transfer heat away from the contact portions 34. This significantly reduces the operating temperature of the sealing ring 3, effectively preventing rapid aging due to high temperatures and significantly extending the service life of the sealing ring.

[0025] As a further technical solution provided by this utility model, inlet and outlet water pipes 41 connected to the cooling ring channel 44 are symmetrically fixedly installed on the cooling machining part 4.

[0026] Specifically, such as Figure 1 As shown, the inlet and outlet water pipes 41 are fixedly welded to the cooling machined part 4. By connecting the inlet and outlet water pipes 41 to the water cooling circulation equipment, continuous circulating water cooling of the cooling ring channel 44 is achieved. The cooling machined part 4 has symmetrically formed channels for connecting the inlet and outlet water pipes 41 and the cooling ring channel 44.

[0027] Furthermore, multiple protrusions 15 are fixedly installed in the notch 14 on the inner ring plate 13, and multiple slots 33 corresponding to the multiple protrusions 15 are provided on the mounting block 32 at the bottom of the sealing ring 3. An mounting ring 12 is fixedly installed on the top of the inner ring plate 13.

[0028] Specifically, the inner ring plate 13, the mounting plate frame 1, the convex tube 11 and the mounting ring 12 are integrated into one structure. By placing the mounting block 32 on the sealing ring 3 into the notch 14, multiple protrusions 15 are inserted into multiple slots 33 respectively, thereby limiting the sealing ring 3 and preventing the sealing ring 3 from being moved by the shaft when it contacts the shaft.

[0029] Furthermore, the outer wall of the sealing ring 3 is symmetrically provided with a first heat sink 37 on the side of the contact portion 34, and the outer wall of the sealing ring 3 is provided with a second heat sink 36 on the side of the extension portion 35.

[0030] Specifically, the first heat sink 37 and the second heat sink 36 are integrally formed with the sealing ring 3. The first heat sink 37 and the second heat sink 36 are used to improve the heat dissipation effect of the contact portion 34, while the second heat sink 36 can guide the flow of liquid in the cooling ring channel 44.

[0031] Furthermore, an alignment sealing ring 2 is movably disposed on the inner ring plate 13, and an inner plate 21 is disposed inside the alignment sealing ring 2. The protruding ring 38 disposed at the bottom of the sealing ring 3 is movably disposed in the annular groove 22 opened on the inner plate 21.

[0032] Specifically, when the alignment sealing ring 2 is placed on the inner ring plate 13, and then the mounting block 32 on the sealing ring 3 is placed in the notch 14, the sealing ring 3 covers the alignment sealing ring 2. At this time, the convex ring 38 provided at the bottom of the sealing ring 3 is movably disposed in the annular groove 22 opened on the inner plate 21. Thus, the sealing effect inside the emulsifier body is improved by the compression and adhesion between the sealing ring 3 and the alignment sealing ring 2.

[0033] Furthermore, a pressure plate 42 is provided on the cooling machine part 4, and the pressure edge 31 provided on the top of the sealing ring part 3 is movably disposed on the pressure plate 42, and a fixing plate 5 is movably disposed on the pressure plate 42.

[0034] Specifically, the pressure edge 31 and the sealing ring 3 are an integral structure, while the pressure guard plate 42 and the cooling machined part 4 are an integral structure. The pressure edge 31 is placed on the pressure guard plate 42, and then the fixing plate 5 is fixed to the pressure guard plate 42 with bolts to compress and fix the pressure edge 31.

[0035] Furthermore, the inner corners of the pressure plate 42 are provided with chamfered portions 43.

[0036] Specifically, the chamfered portion 43 reduces pressure wear between the pressure edge 31 and the pressure guard plate 42.

[0037] Furthermore, when the pressure inside the cooling ring channel 44 increases, the extension 35 moves toward the shaft axis.

[0038] Specifically, the pressure change within the cooling ring channel 44 can drive the extension portion 35 to extend and finely adjust towards the shaft side, thereby increasing the contact area and compression force between the contact portion 34 and the shaft, thus improving the sealing effect.

[0039] Furthermore, the sealing ring 3 is a wear-resistant rubber ring.

[0040] Furthermore, the positioning sealing ring 2 is a flexible rubber ring.

[0041] Working principle: The cooling machined part 4, installed in the convex tube 11 of the mounting plate frame 1, has a cooling ring channel 44 connected to an external water cooling device via inlet and outlet water pipes 41, forming a forced circulation liquid cooling system. This system directly and rapidly removes the heat generated by the friction between the contact portion 34 of the sealing ring 3 and the shaft, effectively reducing its operating temperature and preventing aging. During this process, the increased pressure within the cooling ring channel 44 drives the extension portion 35 of the sealing ring 3 to move slightly towards the shaft center, thereby enhancing the contact portion 34's adhesion to the shaft and achieving self-adjusting sealing. The cooling machined part 4 presses against the sealing ring 3 and the aligning sealing ring 2 on the inner ring plate 13, thus fixing the sealing ring 3 and the aligning sealing ring 2. Simultaneously, the sealing ring 3 and the aligning sealing ring 2 cooperate to seal the cooling ring channel 44. To improve heat dissipation efficiency, the sealing ring 3 is provided with an integrally formed first heat sink 37 and a second heat sink 36. In terms of mechanical fixation, the sealing ring 3 is limited by the mounting block 32 at the bottom and the slot 33 on it, which is inserted into the protrusion 15 in the notch 14 of the inner ring plate 13 to prevent circumferential movement; the pressing edge 31 at the top is pressed by the fixing plate 5 onto the pressure guard plate 42 of the cooling machined part 4; at the same time, the protruding ring 38 at the bottom of the sealing ring 3 is embedded in the annular groove 22 of the aligning sealing ring 2, and the two are squeezed and adhered together to enhance the overall sealing performance.

[0042] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
