Abstract
Description
Technical Field
[0001] This application relates to the field of electronic chemicals, particularly the field of photosensitizer production, and especially to a dispersion disc for a disperser. Background Technology
[0002] Photosensitizers are generally multi-component products containing a specified amount. The homogeneity of the product is required to be high. If the product is not homogeneous, the content will be different between different samples, resulting in great differences in performance, or even making it unusable.
[0003] Drawing inspiration from the coatings industry, a disperser is introduced to uniformly mix the photosensitizer. The dispersing disc is typically connected to the end of a rotating shaft. Through the rapid rotation of the shaft, the dispersing disc continuously rotates, creating a turbulent zone at its edge, thus dispersing the material evenly. Currently, dispersing discs are commonly made of stainless steel such as 304 and 316L. However, in photosensitizer production, stainless steel can introduce metallic impurities, failing to meet the requirements for electronic chemicals. Furthermore, existing dispersing discs and shafts are non-detachable, making cleaning difficult. Additionally, the fixed parameters such as the number and position of the dispersing disc and dispersing teeth result in ineffective dispersion of the photosensitizer at different locations, affecting product performance. Utility Model Content
[0004] In view of the above-mentioned problems in the prior art, the embodiments of this application propose a dispersing disc for a disperser, which can be disassembled for thorough cleaning to avoid mixing of materials.
[0005] According to one aspect of this application, a dispersing disc for a dispersing machine is provided. The dispersing disc has a split assembly structure and includes a rotating shaft fixing member, a dispersing disc body, and dispersing teeth. The rotating shaft fixing member consists of two symmetrical first fixing members and second fixing members, which are fastened together by fasteners to lock the dispersing disc body onto the rotating shaft of the dispersing machine. The dispersing disc body extends radially outward from the outer side wall of the rotating shaft fixing member. The dispersing teeth are evenly arranged on the outer edge of the dispersing disc body.
[0006] In some embodiments, the dispersion disc is made of polytetrafluoroethylene.
[0007] In some preferred embodiments, the thickness of the dispersing teeth is greater than or equal to 5 mm.
[0008] In some embodiments, the dispersing teeth are perpendicular to the horizontal plane or have an inclined angle between the dispersing teeth and the vertical plane, with the inclined angle being between 10 and 15 degrees. In some preferred embodiments, the inclined angle is 10 degrees.
[0009] In some embodiments, after assembly, the shaft fixing member has a hollow structure, and the inner surface of the shaft fixing member fits tightly against the outer surface of the shaft. In some preferred embodiments, the cross-section of the shaft hole between the first fixing member and the second fixing member is circular, elliptical, or square.
[0010] In some embodiments, the fastener is a bolt, stud, or clip. In some preferred embodiments, the fastener is made of polytetrafluoroethylene (PTFE).
[0011] In some embodiments, the wall thickness of the circumferential sidewall of the pivot fastener is greater than or equal to 35 mm.
[0012] In some preferred embodiments, when the fastener is a bolt or stud, the shaft fixing member has an end wall through which the bolt or stud passes, and the wall thickness of the end wall is greater than or equal to 20 mm.
[0013] In some embodiments, the rotating shaft retainer has an upper half located above the dispersing disc and a lower half located below the dispersing disc, and the dispersing disc has a through hole after assembly.
[0014] In some embodiments, the shaft fixing member has an upper half located above the dispersing disc body and no lower half located below the dispersing disc body; the dispersing disc also includes a sealing structure that seals the through hole between the first fixing member and the second fixing member to support and limit the shaft.
[0015] In some preferred embodiments, the top surface of the sealing structure is planar.
[0016] In some embodiments, after assembly, the dispersion disc is annular.
[0017] In some embodiments, the top surface of the dispersion disk is a smooth curved surface.
[0018] In some embodiments, the dispersing teeth include a plurality of upper teeth protruding from the top surface of the dispersing disc and a plurality of lower teeth protruding from the bottom surface of the dispersing disc.
[0019] In some preferred embodiments, the upper and lower teeth are staggered along the circumference of the dispersion disc.
[0020] The beneficial technical effects of this utility model are as follows:
[0021] The dispersion disc in this embodiment has a split assembly structure, allowing it to be disassembled for cleaning and preventing mixing between different batches of photosensitizers, thus avoiding contamination. The rotating shaft fixing component in this embodiment uses fasteners to secure the first and second fixing components, locking the dispersion disc onto the rotating shaft of the disperser. The position of the dispersion disc on the shaft can be freely adjusted to achieve effective dispersion of the photosensitizer. The dispersion disc in this embodiment is made of polytetrafluoroethylene (PTFE), which at least avoids the introduction of metallic impurities and meets the requirements for electronic chemicals. The dispersion teeth of the dispersion disc in this embodiment have a thickness of 5 mm or more, which at least solves the defect of easily deformable dispersion teeth caused by the use of PTFE material.

All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

Reference numerals and / or letters may be repeated in various examples of the present invention.

[0028] Furthermore, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific structures shown in the figures are merely illustrative and are not intended to limit the scope of this application. Other structures not described in the figures may be provided according to actual needs when describing specific figures, and are not intended to limit the scope of this application.
[0029] Figure 1 This is a perspective view of a dispersion disk (after assembly) according to an embodiment of this application. Figure 2 This is a perspective view of the dispersion disk before assembly, according to one embodiment of this application. (Reference) Figure 1 and Figure 2 As shown, Figure 1 and Figure 2 A perspective view of a dispersing disc in different states is shown. According to some embodiments of this application, a dispersing disc 10 for a dispersing machine is provided. The dispersing disc 10 has a split assembly structure and includes a rotating shaft fixing member 11, a dispersing disc body 12, and dispersing teeth 13. The rotating shaft fixing member 11 consists of two symmetrical first fixing members 111 and second fixing members 112. The first fixing members 111 and second fixing members 112 are fastened together by fasteners (not shown in the figure) to lock the dispersing disc body 12 onto the rotating shaft (not shown in the figure) of the dispersing machine. The dispersing disc body 12 extends radially outward from the outer side wall 113 of the rotating shaft fixing member 11. The dispersing teeth 13 are evenly arranged on the outer edge of the dispersing disc body 12. The dispersing teeth 13 can be arranged sequentially around the circumference of the dispersing disc body 12 at the outer edge of the dispersing disc body 12. In some embodiments, the projection of the dispersing teeth 13 on the vertical plane can be trapezoidal, rectangular, or parallelogram.
[0030] The dispersion disc 10 provided in this application has a split assembly structure. The dispersion disc 10 can be detached from the rotating shaft for cleaning, thus avoiding mixing between different batches of photosensitizers and preventing contamination. In this embodiment, the rotating shaft fixing member 11 uses fasteners to engage and secure the first fixing member 111 and the second fixing member 112, locking the dispersion disc body 12 onto the rotating shaft of the disperser. The position of the dispersion disc body on the rotating shaft can be freely adjusted to achieve effective dispersion of the photosensitizer. Multiple dispersion discs 10 can also be provided on the rotating shaft as needed.
[0031] In some embodiments, the dispersion disk 10 can be made of polytetrafluoroethylene (PTFE), meaning that the rotating shaft fixing part 11, the dispersion disk body 12, and the dispersion teeth 13 are all made of PTFE. The PTFE dispersion disk, when used in the production of photosensitizers, does not introduce metallic impurities and meets the requirements for electronic chemicals. The dispersion disk 10 of this application has a simple structure, readily available materials, and requires minimal investment.
[0032] In some preferred embodiments, the thickness D1 of the dispersing teeth 13 is greater than or equal to 5 mm; more preferably, the thickness D1 of the dispersing teeth 13 is 5 mm. The thickness of the dispersing teeth 13 is a radial dimension, that is, the vertical distance between the inner surface of the dispersing teeth 13 near the dispersing disk 12 and the outer surface away from the dispersing disk 12 is the thickness of the dispersing teeth 13. A thickness D1 greater than or equal to 5 mm is beneficial in reducing the risk of deformation of the dispersing teeth 13, especially when the material of the dispersing teeth 13 is polytetrafluoroethylene (PTFE), it can reduce the risk of deformation of PTFE dispersing teeth. Figure 2 An enlarged schematic diagram of the dispersion tooth 13 is shown in the figure. Figure 2 As shown, the dispersing teeth 13 can be a uniform sheet structure. In other embodiments, the root of the dispersing teeth 13 connected to the dispersing disk 12 can be thicker than the protrusion (the part of the dispersing teeth 13 that protrudes from the top or bottom surface of the dispersing disk 12).
[0033] In some embodiments, the dispersing teeth 13 may be perpendicular to the horizontal plane or may have an inclined angle α with the vertical plane, the inclined angle α being between 10 and 15 degrees, more preferably 10 degrees. When the dispersing teeth 13 have an inclined angle α with the vertical plane, the dispersing teeth 13 are inclined away from the central axis of the dispersing disk 12, i.e., inclined outward. The inclined angle α between the dispersing teeth 13 and the vertical plane can optimize dispersion efficiency, enhance fluid turbulence, and improve the uniformity of material mixing. If the dispersing teeth 13 are perpendicular to the horizontal plane, i.e., vertical (parallel to the axis), high-speed rotation will only generate radial shear force on the material, and the axial flow of the material will be very weak. Some material may adhere to the bottom or top of the container, forming a "blind zone," resulting in incomplete dispersion.
[0034] In some embodiments, after assembly, the pivot fixing member 11 has a hollow structure, and its inner surface 114 is tightly fitted with the outer surface of the pivot. The pivot fixing member 11 is coaxially fixed relative to the pivot, and the tight fit ensures coaxiality. In some preferred embodiments, the cross-section of the shaft hole between the first fixing member 111 and the second fixing member 112 can be circular, elliptical, or square. When the cross-section of the shaft hole is circular, the inner surface 114 of the pivot fixing member 11 is an arc surface (or cylindrical surface), and the pivot is correspondingly a cylinder; when the cross-section of the shaft hole is square, the inner surface 114 of the pivot fixing member 11 consists of multiple planes joined together, and the pivot is correspondingly a square prism, such as a cuboid.
[0035] In some embodiments, the fastener can be a bolt, stud, or clip. When the fastener is a bolt or stud, the shaft fixing member 11 has a fixing hole 115, through which the bolt or stud can pass to cooperate with the nut to increase the tightening effect. Although Figure 2 The figure shows two fixing holes 115 on each of the top and bottom sides, for a total of eight fixing holes 115 for accommodating fasteners. However, the number of fixing holes 115 / fasteners can be set according to requirements. The height of the rotating shaft fixing member 11 can also be adjusted according to the number of fasteners. When the fastener is a snap-fit, although the arrangement is not shown in the figure, those skilled in the art can make adaptive adjustments to the structure, such as eliminating the fixing holes 115 and setting snap-fits. In some preferred embodiments, the fastener is made of polytetrafluoroethylene (PTFE), which avoids the use of metal materials and the introduction of metal impurities that could affect the quality of the photosensitizer.
[0036] refer to Figure 2 As shown, in some embodiments, the wall thickness D2 of the circumferential sidewall of the pivot fixing member 11 is greater than or equal to 35 mm. The wall thickness of the circumferential sidewall of the pivot fixing member 11 is a radial dimension, that is, the vertical distance between the inner sidewall 114 and the outer sidewall 113 of the pivot fixing member 11.
[0037] refer to Figure 2 As shown, in some embodiments, when the fastener is a bolt or stud, the shaft fixing member 11 has an end wall through which the bolt or stud passes, and the wall thickness D3 of the end wall is greater than or equal to 20 mm.
[0038] The wall thickness D2 of the circumferential sidewall of the rotating shaft fastener 11 is greater than or equal to 35 mm, and the wall thickness D3 of the end wall is greater than or equal to 20 mm. This helps to reduce the risk of deformation of the rotating shaft fastener 11. In particular, when the material of the rotating shaft fastener 11 is polytetrafluoroethylene, it can reduce the risk of deformation of the polytetrafluoroethylene rotating shaft fastener.
[0039] In some embodiments, the rotating shaft fixing member 11 has an upper half 116 located above the dispersion disk body 12 and a lower half 117 located below the dispersion disk body 12. After assembly, the dispersion disk 10 has a through hole 118, and the dispersion disk 10 can be installed at any height on the rotating shaft to achieve effective dispersion of the photosensitizer. That is, after assembly, the space between the upper half 116 and the lower half 117 is through, and there is a through hole 118 between the first fixing member 111 and the second fixing member 112. It should be understood that, as Figure 2 As shown, the upper half 116 and the lower half 117 are symmetrical. Due to the different viewing angles, in Figure 1 It was not clearly shown in the middle.
[0040] Figure 3 This is a perspective view of the dispersion disk before assembly, according to another embodiment of this application. (See reference) Figure 3 As shown, in some embodiments, the shaft fixing member 11 has an upper half 116 located above the dispersing disc body 12, but no lower half located below the dispersing disc body 12; the dispersing disc 10 may also include a sealing structure 119, which seals the through hole between the first fixing member 111 and the second fixing member 112 to support and limit the shaft. In some preferred embodiments, the top surface of the sealing structure 119 is a plane.
[0041] Continue to refer to Figure 1 and Figure 2 As shown, in some embodiments, after assembly, the dispersion disc 12 can be annular.
[0042] In some embodiments, the top surface 120 of the dispersing disc 12 is a smooth curved surface, and at a certain point on the intersection line of the dispersing disc 12 and the rotating shaft fixing member 11, the angle formed by the tangent of the curved surface and the tangent of the surface of the rotating shaft fixing member 11 is an obtuse angle. The smooth curved surface prevents material from accumulating on the dispersing disc 12. It should be understood that in some embodiments, both the top surface 120 and the bottom surface of the dispersing disc 12 can be smooth curved surfaces; in other embodiments, the top surface 120 of the dispersing disc 12 is a smooth curved surface, and the bottom surface can be a plane.
[0043] In some embodiments, the dispersing teeth 13 include a plurality of upper teeth 131 protruding from the top surface 120 of the dispersing disk 12 and a plurality of lower teeth 132 protruding from the bottom surface of the dispersing disk 12. In some embodiments, the upper teeth 131 and lower teeth 132 are arranged alternately along the circumference of the dispersing disk 12. It should be understood that the so-called alternate spacing is set such that along the circumference of the dispersing disk 12, one upper tooth 131 is provided and one lower tooth 132 is provided, and so on, with the upper teeth 131 and lower teeth 132 arranged sequentially.
[0044] In some embodiments, the rotating shaft fixing member 11, the dispersing disk body 12, and the dispersing teeth 13 of the dispersing disk 10 are integrally formed, for example, by 3D printing.
[0045] To ensure uniform mixing of electronic-grade photosensitizers without introducing metallic impurities, the dispersion disc of this application has the following characteristics: 1. The dispersion disc, made of polytetrafluoroethylene (PTFE), possesses excellent chemical stability, corrosion resistance, and high lubricity and non-stick properties, without introducing metallic impurities, meeting the requirements of electronic chemicals. 2. Depending on the structure, it can be used at the end of the rotating shaft or at any other location in the middle of the shaft, ensuring uniform dispersion of materials (e.g., photosensitizers), and is also suitable for the mixing and dispersion of other electronic-grade chemicals. 3. The fasteners are easy to disassemble; for different products, the dispersion disc can be removed for cleaning by disassembling the fasteners, avoiding material mixing. 4. The structural design reduces the risk of deformation of the dispersion disc (e.g., dispersion teeth). 5. The structure is simple, easy to manufacture, and requires less investment.
[0046] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
