Description

Technical Field

[0001] The utility model relates to the technical field of emulsifier seals, and particularly relates to a sealing device for emulsification. Background Art

[0002] Rubber emulsification is a physical process of mixing rubber or a rubber solution with water, and through specific equipment such as an emulsifier for stirring, shearing, and dispersing, so that rubber particles form a stable dispersion in water.

[0003] The existing patent CN220460562U discloses a vacuum emulsifier. For a vacuum emulsifier of the utility model, when the driving motor is started, the output bevel gear is driven to rotate through the output shaft. Since the output bevel gear is in mechanical transmission with the first bevel gear, the main stirring shaft drives the main stirring frame to rotate inside the emulsification tank. And since one end of the transmission assembly is in mechanical transmission with the first bevel gear and the other end of the transmission assembly is in mechanical transmission with the corresponding second bevel gear, the second bevel gear is driven to rotate through the transmission assembly, and then the auxiliary stirring shaft drives the auxiliary stirring frame to rotate inside the emulsification tank. With the above structure, through one driving motor, power can be provided for the rotation of the main stirring frame and the two auxiliary stirring frames, and the production cost is lower.

[0004] The above technical solution solves the problem of high production cost that requires two reverse rotation motors and one forward rotation motor to jointly provide power by arranging a first gear body and a second gear body, and the driving motor drives the second gear body to rotate through the cooperation of the output bevel gear and the first gear body, and the second gear body drives the two stirring frames to rotate and stir through the cooperation of multiple transmission gears and bevel gears.

[0005] However, in actual use, there are still the following deficiencies. For example, since no sealing structure is installed between the main stirring shaft, the auxiliary stirring shaft and the sealing cover, there may be gaps between the main stirring shaft, the auxiliary stirring shaft and the sealing cover, resulting in possible leakage of the vacuum emulsification sealing device, which is not conducive to improving the sealing performance of the emulsification sealing device, affecting the vacuum degree, and not conducive to maintaining stable sealing performance. Therefore, the utility model proposes a sealing device for emulsification. Summary of the Utility Model

[0037] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0038] As Figure 1 - Figure 6 shown, this embodiment provides a technical solution: a sealing device for emulsification, including a machine base 1, an emulsification component 2, and a sealing component 3. The emulsification component 2 is arranged on the machine base 1, a closing component 4 is arranged on the emulsification component 2, a sealing component 3 is arranged between the emulsification component 2 and the closing component 4, and an elastic component 5 is arranged inside the sealing component 3;

[0039] As Figure 2 shown, the emulsification component 2 includes an emulsification tank 21 and a rotating shaft 22. The emulsification tank 21 is arranged on the machine base 1, and the rotating shaft 22 is arranged inside the emulsification tank 21;

[0040] As Figure 3 shown, the sealing component 3 includes a housing 31 and a stationary ring 32. The housing 31 is sleeved on the rotating shaft 22, a transmission sleeve 34 is arranged between the housing 31 and the rotating shaft 22, movable rings 33 are clamped at both ends of the housing 31, the stationary ring 32 is threadedly connected to one end of the housing 31 close to the movable ring 33, and a first packing 35 is sleeved on one end of the stationary ring 32 close to the movable ring 33;

[0041] As Figure 3 - Figure 4As shown, the elastic component 5 includes a support ring 51 and an annular elastic sheet 52. The support ring 51 is fixedly connected to the inner side of the transmission sleeve 34 close to the rotating shaft 22. One end of the transmission sleeve 34 close to the moving ring 33 is provided with a push plate 53. The annular elastic sheet 52 is arranged between the support ring 51 and the push plate 53. The support ring 51 and the push plate 53 are fixedly connected with a limit post 54 at one end close to the annular elastic sheet 52. The annular elastic sheet 52 is clamped with the support ring 51 and the annular elastic sheet 52 through the limit post 54. The number of annular elastic sheets 52 arranged at both ends of the support ring 51 is four. A clamp 55 is arranged on the annular elastic sheet 52 on the same side. By welding the outer shell 31 to the top cover 41, the outer shell 31 and the top cover 41 are sealed. By cooperating the static ring 32 and the moving ring 33, a plurality of barriers are formed between the rotating shaft 22 and the outer shell 31 to block the air leakage path, realizing the sealing between the rotating shaft 22 and the top cover 41. However, during the long-term use of the sealing device, ordinary springs may have reduced elasticity due to fatigue, corrosion, etc., thus affecting the sealing performance. Therefore, by stacking a plurality of annular elastic sheets 52 inside the transmission sleeve 34, since the annular elastic sheet 52 is a wavy annular structure, it has higher strength and stiffness than ordinary springs and elastic sheets and is not easily deformed. Then, by clamping the clamp 55 on the annular elastic sheet 52, the multi-layer annular elastic sheets 52 are kept in a relatively stable overall structure, enabling the annular elastic sheet 52 to push the moving ring 33 through the push plate 53 to keep sealing with the static ring 32. Thus, the sealing component 3 and the elastic component 5 cooperate to solve the problem that there may be gaps in the sealing device, resulting in possible leakage of the vacuum emulsification sealing device, which is beneficial to improving the sealing performance of the emulsification sealing device. At the same time, it is also beneficial to maintain a stable sealing performance.

[0042] Furthermore, as Figure 2 shown, a motor 23 is fixedly connected to one side of the machine base 1 close to the rotating shaft 22. The output end of the motor 23 is fixedly connected to the rotating shaft 22. A homogenizing head 24 is fixedly connected to one end of the rotating shaft 22 away from the motor 23. A stirring rod 25 is fixedly connected to one end of the rotating shaft 22 close to the inside of the emulsification tank 21. Stirring blades 26 are fixedly connected to both the stirring rod 25 and the rotating shaft 22. By the cooperation of the rotating shaft 22 and the stirring rod 25, the stirring blades 26 are driven to rotate at a high speed, generating a strong shearing force on the material, fully mixing two or more immiscible liquids to form a uniform emulsion. At the same time, the shearing force can also break the agglomerates in the material to prevent particle precipitation and stratification.

[0043] Furthermore, as Figure 3As shown in the figure, a clamping block 6 is fixedly connected to one end of the moving ring 33 close to the transmission sleeve 34. A clamping groove 7 is formed at one end of the transmission sleeve 34 close to the clamping block 6. The moving ring 33 is clamped to the transmission sleeve 34 through the clamping block 6 and the clamping groove 7. By the cooperation of the clamping block 6 and the clamping groove 7, the moving ring 33 is clamped inside the transmission sleeve 34. Then, the transmission sleeve 34 is installed on the rotating shaft 22 through bolts. Thus, when the transmission sleeve 34 rotates following the rotating shaft 22, it can drive the moving ring 33 to rotate together.

[0044] Furthermore, as Figure 4 shown in the figure, a sliding groove 56 is formed on one side of the transmission sleeve 34 close to the fixture 55. The fixture 55 is slidably connected to the transmission sleeve 34 through the sliding groove 56. By sliding the fixture 55 inside the sliding groove 56, when the annular elastic sheet 52 deforms, the fixture 55 moves on the sliding groove 56 following the change of the annular elastic sheet 52, thereby ensuring the normal use of the annular elastic sheet 52.

[0045] Furthermore, as Figure 4 shown in the figure, a rubber block 57 is fixedly connected to one side of the fixture 55 close to the annular elastic sheet 52. A fixing groove 58 is formed on one side of the annular elastic sheet 52 close to the rubber block 57. The fixture 55 is clamped to the annular elastic sheet 52 through the rubber block 57 and the fixing groove 58. By pushing the annular elastic sheet 33, the rubber block 57 on the annular elastic sheet 52 is clamped inside the fixing groove 58, thereby facilitating the installation of the annular elastic sheet 52 and being beneficial to improving the installation efficiency.

[0046] In order to further improve the sealing effect of the emulsification sealing device and solve the problem of the gap between the emulsification tank 21 and the top cover 41, as Figure 6 shown in the figure, the closing assembly 4 includes a top cover 41 and a base 42. The top cover 41 is fixedly connected to the outer shell 31. The base 42 is fixedly connected to one end of the emulsification tank 21 close to the top cover 41. An inner groove 43 is formed on one side of the base 42 close to the top cover 41. The top cover 41 is clamped to the base 42 through the inner groove 43. A second sealing groove 45 is formed inside the base 42 close to the top cover 41. A second packing 44 is sleeved inside the second sealing groove 45. The hydraulic telescopic rod installed on the machine base 1 is used to push the top cover 41 towards the direction of the emulsification tank 21, so that the top cover 41 is inserted into the base 42 through the inner groove 43. At this time, the gap between the top cover 41 and the base 42 is sealed through the inner groove 43, thereby solving the problem of the gap between the emulsification tank 21 and the top cover 41, being beneficial to further improving the sealing performance of the emulsification sealing device and avoiding affecting the vacuum degree of the emulsification sealing device.

[0047] Working principle: As Figure 1 - Figure 6 shown in the figure:

[0048] During use: First, install the drive sleeve 34 on the rotating shaft 22 through bolts. Then, install a stationary ring 32 at the inner bottom of the housing 31. Stack multiple annular elastic sheets 52 together, push the fixture 55, so that the rubber block 57 on the fixture 55 is clamped inside the fixing groove 58 on the annular elastic sheet 52, making the fixture 55 clamp the multiple annular elastic sheets 52 together. Then, push the annular elastic sheet 33 and the fixture 55, so that the annular elastic sheet 52 and the fixture 55 are installed inside the drive sleeve 34 along the sliding groove 56. After that, place the push plate 53 on the annular elastic sheet 52, so that the support ring 51 and the limit posts 54 on the annular elastic sheet 52 are clamped inside the annular elastic sheet 52 to fix the annular elastic sheet 52. Then, the rotating shaft 22 drives the drive sleeve 34 to be inserted into the housing 31, ensuring that both ends of the housing 31 are sealed through the stationary ring 32 and the stationary ring 32, thereby forming multiple barriers inside the housing 31 to block the air leakage path and providing double protection. After the installation is completed, start the hydraulic telescopic rod provided on the machine base 1, so that the top cover 41 moves towards the base 42, and the top cover 41 is inserted into the base 42 through the inner groove 43, so that the inner groove 43 seals the gap existing between the top cover 41 and the base 42. Finally, start the motor 23, and the motor 23 drives the homogenizing head 24 and the stirring rod 25 to rotate through the rotating shaft 22. The homogenizing head 24 and the stirring blades 26 inside the emulsifying tank 21 mix rubber, emulsifier, etc. together through the strong shearing, dispersion, impact, etc. generated by the high-speed rotation, making the rubber particles evenly dispersed in the water phase to form a stable emulsion.

[0049] The above is only the preferred embodiment of the present invention, and it does not limit the present invention in other forms. Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical solution content of the present invention, any simple modification, equivalent change, and modification made to the above embodiments based on the technical essence of the present invention still fall within the protection scope of the technical solution of the present invention.
