The high-speed dispersion mechanism composed of a dispersion moving disc and a dispersion stationary ring inside the dispersion and homogenization system can effectively mix and stir the materials, and the dispersion and homogenization effect of the dispersion section is good.

[0061] To further illustrate the technical means and effects adopted by the present invention to achieve the intended purpose, the following, in conjunction with the accompanying drawings and preferred embodiments, details the specific implementation, structure, features, and effects of an integrated dispersion homogenization and defoaming device and its operating method according to the present invention. In the following description, different "embodiments" or "embodiments" do not necessarily refer to the same embodiment. Furthermore, specific features, structures, or characteristics in one or more embodiments can be combined in any suitable form.

[0062] In this article, the term "and / or" is merely a description of the relationship between related objects, indicating that there can be three relationships, such as A and / or B. Specifically, it can mean that A and B can be included at the same time, A can exist alone, or B can exist alone, and any of the above three situations can be met.

[0063] Integrated dispersion, homogenization, and defoaming device

[0064] See appendix Figure 1 - Appendix Figure 12The integrated dispersion, homogenization, and degassing device provided in this embodiment of the invention includes a dispersion and homogenization section 26, a degassing section 1, a degassing material outlet 10, a degassing material inlet 11, and a vacuum pipeline system 16. The dispersion and homogenization section 26 has a first accommodating space, and the degassing section 1 has a second accommodating space. The dispersion and homogenization section 26 and the degassing section 1 are connected via the degassing material outlet 10 and the degassing material inlet 11, respectively, allowing material to flow between the first and second accommodating spaces. The degassing section 1 is connected to the vacuum pipeline system 16, allowing air bubbles contained in the dispersed material to escape in a vacuum environment and be removed by the vacuum pipeline system 16.

[0065] In the application of the integrated dispersion, homogenization, and degassing device provided in this embodiment of the invention, the material is first uniformly dispersed in the dispersion and homogenization section 26. Then, the dispersed and homogenized material flows between the first accommodating space of the dispersion and homogenization section 26 and the second accommodating space of the degassing section through the degassing material outlet 10 and the degassing material inlet 11. In the degassing section 1, the bubbles are removed by the vacuum pipeline system 16. Through repeated circulation, the material can be completely degassed, with high degassing efficiency and low cost.

[0066] The degassing section 1 includes a degassing rotor 5, which comprises a first conical rotating body and a second conical rotating body. The larger diameter edges of the first and second conical rotating bodies are fitted together, and the first and second conical rotating bodies are fixedly connected together via their larger diameter edges, forming a third accommodating space with a larger axial height at the rotation center and a smaller axial height at the radial edges. The material outlet 10 and the material inlet 11 of the degassing material are both located within this third accommodating space. In this configuration, the dispersed and homogenized material can fully collide and shear against the sidewalls of the first and second conical rotating bodies during the rotation of the degassing rotor 5, resulting in more thorough exposure of air bubbles in the dispersed and homogenized material and a significantly increased probability of them being removed by the vacuum pipeline system 16, thereby achieving higher degassing efficiency.

[0067] In this configuration, the material outlet of the deaerated material outlet 10 and the material inlet of the deaerated material inlet 11 are located opposite to each other. In this configuration, the travel distance of the dispersed and homogenized material within the deaerated rotor 5 is increased, thereby increasing the exposure opportunity of bubbles hidden in the dispersed and homogenized material. The probability of these bubbles being removed by the vacuum pipeline system 16 is greatly increased, thus achieving higher deaeration efficiency.

[0068] In this design, the material inlet 11 is inclined, with its height gradually decreasing from near the spindle of the deaeration rotor 5 towards the centrifugal position. In this configuration, the travel distance between the dispersed and homogenized material entering the deaeration rotor 5 from the deaeration material inlet 11 and the conical inner wall is slightly increased, thus slightly extending the travel distance and increasing the exposure opportunity of air bubbles hidden within the dispersed and homogenized material. Furthermore, a buffer space is formed between the deaeration material inlet 11 and the conical inner wall, increasing the discharge volume of the dispersed and homogenized material from the deaeration material inlet 11 and further improving the deaeration efficiency of the dispersed and homogenized material.

[0069] In this design, the radial cross-section of the material inlet 11 has a first inclination angle, forming a first slope; the radial cross-section of the first conical rotating body of the deaerating rotor 5 has a second inclination angle, forming a second slope; the second inclination angle is greater than the first inclination angle, causing the distance between the material inlet 11 and the radial cross-section of the first conical rotating body of the deaerating rotor 5 to gradually increase from a position near the spindle of the deaerating rotor 5 towards the centrifugal position. In this configuration, the shape of the deaerating material inlet 11 can be formed simply by cutting the end of the deaerating material inlet 11, resulting in low cost and ease of implementation.

[0070] The dispersion and homogenization section 26 includes a dispersion cylinder 27 and a dispersion rotor 32. The dispersion rotor 32 is disposed inside the dispersion cylinder 27. In this case, by utilizing the rotation of the dispersion rotor 32, the material can be fully stirred within the dispersion cylinder 27, thus achieving a better dispersion and homogenization effect.

[0071] The dispersing rotor 32 is eccentrically positioned at the bottom of the dispersing cylinder 27. In this configuration, the dispersing cylinder 32 can rotate around the spindle, and the dispersing rotor 32, while rotating on its own axis, also revolves around the spindle. This further enhances the opportunity and method of material mixing within the cylinder 27, resulting in more thorough mixing and improved material dispersion and homogenization. Furthermore, powdered materials tend to settle more easily at the bottom of the dispersing cylinder 27 due to gravity. Positioning the dispersing rotor 32 at the bottom increases the chance of these deposited particles contacting the rotor, further improving the dispersion effect within the dispersing cylinder 27.

[0072] The integrated dispersion, homogenization, and defoaming device further includes a moving disc drive motor 40, a motor end pulley 43, a transmission belt 44, and a dispersion disc end pulley 45. The motor end pulley 43 is fixedly connected to the output shaft of the moving disc drive motor 40, and the dispersion disc end pulley 45 is fixedly connected to the dispersion moving disc drive shaft 34 of the dispersion rotor 32. The motor end pulley 43, transmission belt 44, and dispersion disc end pulley 45 together constitute a belt drive mechanism. In this configuration, the belt drive mechanism can reduce the possibility of vibration generated during the rotation of the output shaft of the moving disc drive motor 40, thereby improving the operating noise of the integrated dispersion, homogenization, and defoaming device provided in this embodiment of the invention and extending its service life.

[0073] The integrated dispersion, homogenization, and degassing device also includes a support end cap 19. The support end cap 19 is mounted on the dispersion cylinder 27 via a flange, creating a closed first accommodating space inside the dispersion cylinder 27. The support end cap 19 is provided with a solid material inlet 21 and a liquid material inlet 23. Solid material enters the dispersion cylinder 27 through the solid material inlet 21, and liquid material enters the dispersion cylinder 27 through the liquid material inlet 23. In this configuration, the solid and liquid materials can fully contact each other within the dispersion cylinder 27, thereby improving the dispersion efficiency of the materials and enhancing the dispersion effect of the integrated dispersion, homogenization, and degassing device provided in this embodiment of the invention.

[0074] The lower outlet of the deaerated material outlet insertion pipe 13 and the lower inlet of the deaerated material outlet insertion pipe 14 are located in the middle of the lowest liquid level of the dispersion cylinder 27. In this case, the deaerated material outlet insertion pipe 13 and the deaerated material outlet insertion pipe 14 can not only further mix the previously deaerated material into the dispersion cylinder 27, but also avoid interference that the dispersion rotor 32 may cause to the deaerated material outlet insertion pipe 13 and the deaerated material outlet insertion pipe 14 during its rotation and revolution, thereby ensuring the operational safety of the integrated dispersion, homogenization and deaeration device provided in this embodiment of the invention.

[0075] The lower outlet of the deaerated material outlet insertion pipe 13 is bent in the direction of material rotation inside the dispersion cylinder 27. The lower inlet of the deaerated material outlet insertion pipe 14 is bent in the opposite direction of material rotation inside the dispersion cylinder 27. In this configuration, the material that re-enters the dispersion cylinder 27 from the deaerated material outlet insertion pipes 13 and 14 can be better integrated into the existing material in the dispersion cylinder 27, further participating in dispersion and homogenization. Through repeated cycles, the material undergoes multiple shearing and stirring processes within the dispersion cylinder 27, resulting in better dispersion and homogenization.

[0076] In this embodiment, the lower outlet of the deaerated material outlet insertion pipe 13 is angled inside the dispersion cylinder 27 in the direction of material rotation. The lower inlet of the deaerated material outlet insertion pipe 14 is angled inside the dispersion cylinder 27 in the opposite direction of material rotation. In this configuration, the material entering the dispersion cylinder 27 through the deaerated material outlet insertion pipes 13 and 14 has a higher flow rate and a longer stroke, thus increasing the opportunity for material agitation. Therefore, the integrated dispersion, homogenization, and deaeration device provided in this embodiment of the invention provides better material dispersion efficiency and homogenization effect.

[0077] In this embodiment, a filter 17 is connected to the vacuum pipeline system 16, and the gas needs to pass through the filter 17 during the vacuuming process. In this case, after degassing by the degassing section 1, as the bubbles are drawn away by the vacuum pipeline system 16, the filter 17 can filter out larger solid particles mixed in with the bubbles. Therefore, under the conditions of the integrated dispersion, homogenization, and degassing device provided in this embodiment of the invention, the dust pollution caused by solid materials mixed in with the bubbles being carried out of the vacuum pipeline system 16 during the degassing process can be reduced or avoided. Furthermore, due to the presence of the filter 17, solid materials mixed in with the bubbles can be trapped inside the integrated dispersion, homogenization, and degassing device provided in this embodiment of the invention, thereby reducing material loss during the degassing process caused by using the integrated dispersion, homogenization, and degassing device provided in this embodiment of the invention. In this embodiment, in order to ensure the safe and stable operation of the integrated dispersion, homogenization and defoaming device provided by the present invention, it is necessary to clean the solid material trapped on the filter 17 frequently. The filter 17 can also be set as a filter with a self-cleaning function, such as a forward and reverse rotation filter. In this case, the material trapped on the filter 17 can be partially thrown off by the forward and reverse rotation of the filter itself. Other self-cleaning filters can also be used to ensure the long-term safe and efficient operation of the integrated dispersion, homogenization and defoaming device provided by the present invention.

[0078] Operation method of integrated dispersion homogenization and defoaming device

[0079] The operation method of the integrated dispersion homogenization and defoaming device provided by the present invention includes the following steps:

[0080] Step S1: Solid materials and liquid materials are dispersed and homogenized in the dispersion and homogenization section 26 to obtain dispersed and homogenized materials;

[0081] Step S2: Vacuum treatment is performed on the degassing section 1 to create a vacuum inside the degassing section 1;

[0082] Step S3: The dispersed and homogenized material is drawn into the degassing section 1 and spread into a film under the centrifugal force of the degassing section 1. The air bubbles contained in the dispersed material are released in the vacuum environment and sucked away by the vacuum system.

[0083] Step S4: Under the action of centrifugal force, the deaerated material enters the dispersion cylinder 27 through the deaerated material outlet insertion pipe 13;

[0084] Step S5: Repeat this process to degas the material.

[0085] In the operation of the integrated dispersion, homogenization, and degassing device provided in this embodiment of the invention, the material is first uniformly dispersed in the dispersion and homogenization section 26. Then, the dispersed and homogenized material flows between the first accommodating space of the dispersion and homogenization section 26 and the second accommodating space of the degassing section through the degassing material outlet 10 and the degassing material inlet 11. In the degassing section 1, the bubbles are drawn away by the vacuum pipeline system 16. Through repeated circulation, the material can be completely degassed, with high degassing efficiency and low cost.

[0086] The working principle of the integrated dispersion, homogenization, and defoaming device provided in this embodiment of the invention is as follows:

[0087] Powdered and liquid materials enter the dispersion cylinder 27 through the solid material inlet 21 and liquid material inlet 23 on the support end cover 19. When the mixture reaches the set liquid level, the dispersion disc 33 rotates at high speed driven by the belt 44. After dispersion for a period of time, the deaeration drive motor 3 is turned on, and the deaeration rotor 5 rotates at high speed. After stable rotation, the vacuum system is turned on. The separation chamber 7 of the upper end cover deaeration section 1 is connected to the vacuum pipeline system 16, forming a vacuum in the separation chamber 7. The vacuum draws the dispersed material into the separation chamber 7 through the deaeration material inlet insertion pipe 14 and sprays it into the double-cone rotor cavity of the high-speed rotating deaeration rotor 5. Under the action of centrifugal force, it spreads into a film. The air bubbles contained in the dispersed material are released in the vacuum environment and are removed by the vacuum system. Under centrifugal force, the deaerated material gathers at the tip of the double-cone separation chamber and enters the dispersion cylinder 27 through the deaerated material outlet insertion pipe 13. After mixing with the undeaerated dispersed material, it continues to be dispersed under the action of the dispersion moving plate 33 and the dispersion stationary ring 42. This process is repeated until the uniformity of the powder particle size and concentration of the dispersed material is detected to meet the requirements. Then, the drive motor of the dispersion moving plate 33 is turned off. Under the action of the vacuum pipeline system 16 and the deaeration section 2, the material continues to undergo vacuum deaeration in the separation chamber 7 until the material is uniform and free of bubbles. Then, the vacuum is turned off first, and then the deaeration rotor motor is turned off. At the same time, the material is discharged through the material outlet 31 of the dispersion cylinder 27, and the vent valve pipe 15 is opened to discharge the deaerated material that overflows or is not completely discharged from the separation chamber 7.
