Description

Technical Field

[0001] This utility model belongs to the field of dispersion technology, and in particular relates to a coating dispersion device for water-based coating production. Background Technology

[0002] In the production process of water-based coatings, the dispersion process is a crucial step in ensuring product quality. Currently, high-speed dispersers, with their efficient dispersion capabilities, have become commonly used equipment in the dispersion production of water-based coatings, with speeds reaching 800-1500 rpm. During dispersion, a vortex is generated around the dispersion disc.

[0003] This phenomenon has two sides: on the one hand, moderate vortexing can promote initial mixing between materials, which helps solid components such as pigments to initially integrate into the water-based system; on the other hand, for the goal of uniform dispersion in water-based coating systems, excessive vortexing has obvious drawbacks—it causes the materials to separate due to centrifugal force, preventing pigments, resins, and other components from fully colliding and fusing, resulting in uneven dispersion and affecting the final performance of the paint film, such as gloss and adhesion. At the same time, vortices easily entrain a large amount of air, forming bubbles. If these bubbles remain in the coating, they can cause defects such as pinholes and craters after the paint film dries, damaging the integrity and aesthetics of the coating. To eliminate bubbles, additional processes such as vacuum degassing and adding defoamers are often required, which not only extends the production cycle but also increases costs due to the introduction of defoamers. Furthermore, excessive defoamers may affect the storage stability and application performance of the coating.

[0004] Therefore, developing a dispersion device that can effectively limit vortices, optimize flow field distribution, and improve the dispersion quality and efficiency of water-based coatings has become a current need for improving water-based coating production equipment. Utility Model Content

[0005] To address the aforementioned problems, the purpose of this invention is to provide a dispersion device that can effectively limit vortices, optimize flow field distribution, and improve the dispersion quality and efficiency of water-based coatings.

[0006] The technical solution of this utility model is as follows:

[0007] A coating dispersion device for water-based coating production includes a base, a mounting frame on the base, and a lifting mechanism on the mounting frame. The lifting mechanism is used to drive a stirring motor to lift. The output shaft of the stirring motor is connected to a dispersion mechanism. The dispersion mechanism includes a stirring shaft. One end of the stirring shaft is connected to the stirring motor through a coupling, and the other end passes through a control cover and is fitted with a dispersion disc at the end. A through-hole is axially formed on the stirring shaft.

[0008] The control cover includes an inverted barrel body, with a mounting ring coaxially located at the upper end of the barrel body. A guide pin is provided radially on the ring wall of the mounting ring, which slides in conjunction with the elongated sliding hole. The outer peripheral surface of the guide pin and the inner wall surface of the elongated sliding hole form a sliding pair.

[0009] At least two inclined guide plates are evenly distributed on the inner ring wall at the lower end of the control cover, and the guide plates extend upward in an inclined manner along the rotation direction of the stirring shaft; at least two inclined guide grooves are evenly distributed on the outer ring wall of the control cover, and the inclination direction of the guide grooves is coordinated with the upward direction of the guide plates.

[0010] The inclined layout of the guide plate and guide channel guides the water-based coating material to form a spiral flow field consistent with the rotation direction of the stirring shaft, suppressing the formation of vortex in the center of the dispersion disk, reducing the stratification phenomenon caused by centrifugal force, and reducing the amount of air entrainment to avoid the formation of bubbles in the coating. In addition, the control cover and the stirring shaft form a sliding pair through the guide pin and the long sliding hole, so that the control cover can be raised and lowered slightly along the axis when the stirring shaft rotates, dynamically adjusting the distance between the control cover and the dispersion disk, further optimizing the flow field distribution, improving the uniformity of water-based coating dispersion, and reducing the problem of decreased gloss and adhesion of the paint film caused by uneven dispersion.

[0011] Furthermore, the barrel is truncated cone-shaped, with its radial dimension gradually narrowing away from the mounting ring. The angle between the generatrix of the truncated cone and the axis of the stirring shaft is 15°~30°. This angle causes the water-based coating material to form an accelerated spiral downward flow on the inner wall of the barrel. Combined with the guide plate and guide groove, this further enhances the suppression effect on vortices and improves the dispersion efficiency.

[0012] Furthermore, one end of the guide plate is fixedly connected to the inner ring wall of the lower end face of the barrel, and the other end extends upward along the inner ring wall to form an end, with a rounded corner away from the inner ring wall. The angle between the extension direction of the guide plate and the radial plane of the control hood is an acute angle, and the angle between the guide plate and the radial plane of the control hood is 20°~35°. When the stirring shaft rotates, the axial thrust generated by the coating flowing along the upward guide plate can drive the control hood to move up and down along the axis of the stirring shaft. By dynamically changing the distance between the control hood and the dispersion disk, the shearing and dispersion effect of the coating is enhanced.

[0013] Furthermore, the free end edge of one side of the inner ring wall of the guide plate is a smooth straight line segment, and the smooth straight line segment is connected to the end through the rounded corner transition. This rounded corner structure enables the coating to form a stable adhesion vortex at the end of the guide plate. The rotation direction of the adhesion vortex is consistent with the rotation direction of the stirring shaft, which suppresses the generation of turbulent vortices, reduces energy consumption, and strengthens the shearing effect between the coating and the dispersion disk.

[0014] Furthermore, the guide plate has at least two protruding ridges on the lower end face near the dispersion disk. The at least two protruding ridges are distributed at intervals along the length direction of the guide plate, and the adjacent protruding ridges form a guide channel. This structure enables the coating to form turbulent micro-vortices in the guide channel, further enhancing the dispersion effect of the vortex, improving the collision and fusion efficiency of pigments, resins and other components in the coating, and avoiding the impact of uneven dispersion on the gloss and adhesion of the paint film.

[0015] Furthermore, the mounting ring has a pair of collinear through holes along the radial direction on its ring wall. The guide pin is inserted into the two through holes. Each of the two through holes has a limiting notch on its inner ring wall. The pin section of the guide pin inserted into the through hole has a positioning block that cooperates with the limiting notch to prevent the guide pin from rotating and affecting the lifting and lowering of the control cover.

[0016] Furthermore, the guide channel is a waist-shaped channel located in the middle of the outer annular wall of the control cover. The angle between the extension direction of the guide channel and the radial plane of the control cover is an acute angle. The upper and lower ends of the guide channel are respectively provided with rounded corners. The angle between the extension direction of the guide channel and the radial plane of the control cover is 30°~45°. This ratio allows the coating to form a laminar-turbulent transition flow field when passing through the guide channel. It works in conjunction with the spiral flow field of the guide plate to further optimize the overall flow field distribution, reduce air entrainment, reduce the probability of coating bubble generation, and avoid defects such as pinholes and shrinkage cavities in the paint film.

[0017] Furthermore, the lower end face of the base has at least four damping mechanisms arranged in a rectangular array. Each damping mechanism includes a mounting cylinder that is perpendicularly fixed to the lower end face of the base and a flexible component coaxially encased within the mounting cylinder. The flexible component has a cavity coaxial with the mounting cylinder, which is closed at the top and open at the bottom. A support seat is inserted into the cavity, and the support seat includes a horizontally arranged base plate with an upwardly extending connecting column. In the assembled state, the base plate abuts against the opening edge of the lower end of the flexible component, and the connecting column is vertically inserted into the inner cavity. This structure can effectively absorb the vibration generated by the suppression of vortices during the operation of the dispersion device, reduce equipment wear, ensure flow field stability, and avoid uneven coating dispersion caused by vibration.

[0018] Furthermore, the connecting column includes a straight rod, with a spherical connector integrally formed at the end of the straight rod away from the base plate, and a hemispherical groove that mates with the spherical connector is provided at the top of the inner cavity of the flexible component.

[0019] Furthermore, the flexible component includes a column and an internal cavity. The lower outer ring wall of the column is provided with an annular groove, and the inner wall of the mounting cylinder is provided with a corresponding mounting boss. The upper part of the column, surrounding the outer side of the cavity, is provided with an upward-opening annular swaying groove. The swaying groove is located between the upper closed structure of the cavity and the top surface of the column. This structure reduces the shear stiffness of the flexible component in the horizontal direction, enhances the absorption capacity of lateral vibration, and, together with the spherical connector, further reduces the vibration transmission during the operation of the dispersion device, stabilizes the flow field distribution, ensures effective suppression of vortices, and improves the uniformity and stability of the dispersion of water-based coatings.

[0020] The beneficial effects of this utility model are as follows:

[0021] 1. The lower inner ring wall of the control cover of this utility model is provided with an upward inclined guide plate, and the outer ring wall is provided with an inclined guide groove with coordinated direction. The two work together to guide the coating to form a spiral flow field in the same direction as the rotation of the stirring shaft, suppress the formation of vortex in the center of the dispersion disk, reduce the centrifugal stratification of materials, reduce the amount of air entrainment, avoid the generation of coating bubbles, and solve the problem of uneven dispersion and bubble defects caused by vortex.

[0022] 2. The control cover of this utility model forms a sliding pair with the guide pin on the mounting ring and the long sliding hole of the stirring shaft, so that the control cover can be raised and lowered axially with the rotation of the stirring shaft, dynamically adjusting the distance between the control cover and the dispersion disk, optimizing the flow field distribution, improving the uniformity of water-based coating dispersion, improving the problem of reduced gloss and adhesion of the paint film caused by uneven dispersion, and ensuring the performance of the paint film.

[0023] 3. The barrel of this utility model is truncated cone-shaped, with the radial dimension narrowing away from the mounting ring. The angle between the generatrix of the truncated cone and the axis of the stirring shaft is 15°~30°, which promotes the coating to form an accelerated spiral downward flow on the inner wall of the barrel. Combined with the guide plate and guide groove, the vortex suppression effect is enhanced, the material flow and mixing are accelerated, the dispersion efficiency is improved, and the production cycle is shortened.

[0024] 4. The base of this utility model is equipped with a rectangular array of shock-absorbing mechanisms at its lower end. A support seat with a ball-shaped connector is inserted into the internal cavity of the flexible component. The flexible component also features an annular swaying groove and an annular locking groove that mate with the mounting cylinder. This structure effectively absorbs vibrations generated by suppressed vortices during equipment operation, reducing equipment wear; it also reduces horizontal shear stiffness, enhances lateral vibration absorption, stabilizes the flow field distribution, ensures vortex suppression effectiveness, improves the uniformity and stability of coating dispersion, and extends equipment lifespan.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0032] like Figures 1 to 5 As shown, a coating dispersion device for water-based coating production includes a base 1, on which a mounting frame 2 is mounted. The mounting frame 2 is L-shaped and consists of a vertical section and a horizontal section. A mounting boss extends from one side of the vertical section, parallel to the horizontal section. Two parallel sliding rods 3 are positioned between the two. A sliding seat 4 is slidably connected to the two sliding rods 3 via linear bearings. A stirring motor 5 is fixed on the sliding seat 4, forming a working unit that can move vertically along the sliding rods 3. A take-up motor 6 is mounted on the base 1 on the other side of the vertical section of the mounting frame 2. The output shaft of the take-up motor 6 is connected to a winding reel, serving as the power component of the lifting system. The transmission components of the lifting system include four guide wheels and a wire rope. The first guide wheel at the top of the sliding seat 4 changes the initial direction of the wire rope, the second guide wheel at the front end of the horizontal section achieves horizontal turning, the third guide wheel at the top of the vertical section completes vertical turning, and the fourth guide wheel at the bottom of the vertical section provides final guidance. One end of the wire rope is fixed to the bottom surface in front of the horizontal slide bar 3 of the mounting frame 2. After passing through four guide wheels in sequence, it is connected to the winding reel to form a transmission circuit. When the winding motor 6 is running, the winding reel winds up and unwinds the wire rope to realize the lifting and lowering of the stirring motor 5. The output shaft of the stirring motor 5 is connected to the dispersing mechanism 7. The dispersing mechanism 7 includes a stirring shaft 7-1. One end of the stirring shaft 7-1 is connected to the stirring motor 5 through a coupling. The other end passes through the control cover 7-2 and is equipped with a dispersing disc 7-3 at the end. The stirring shaft 7-1 has an axially through-hole 7-1.1.

[0033] The control cover 7-2 includes an inverted barrel body, with a mounting ring 7-2.3 coaxially located at the upper end of the barrel body. The ring wall of the mounting ring 7-2.3 is provided radially with a guide pin 7-4 that slides with the elongated sliding hole 7-1.1. The outer peripheral surface of the guide pin 7-4 and the inner wall surface of the elongated sliding hole 7-1.1 form a sliding pair.

[0034] At least two inclined guide plates 7-2.1 are evenly distributed on the inner ring wall at the lower end of the control hood 7-2. The guide plates 7-2.1 extend upwards in an inclined manner along the rotation direction of the stirring shaft 7-1. At least two inclined guide grooves 7-2.2 are evenly distributed on the outer ring wall of the control hood 7-2. The inclination direction of the guide grooves 7-2.2 is coordinated with the upward direction of the guide plates 7-2.1.

[0035] The inclined arrangement of the guide plate 7-2.1 and the guide channel 7-2.2 guides the water-based coating material to form a spiral flow field consistent with the rotation direction of the stirring shaft 7-1, suppressing the formation of the central vortex of the dispersion disk 7-3, reducing the stratification phenomenon of the material caused by centrifugal force, and reducing the amount of air entrainment to avoid the formation of bubbles in the coating. In addition, the control cover 7-2 and the stirring shaft 7-1 form a sliding pair through the guide pin 7-4 and the elongated sliding hole 7-1.1, so that the control cover 7-2 can be raised and lowered slightly along the axis when the stirring shaft 7-1 rotates, dynamically adjusting the distance between it and the dispersion disk 7-3, further optimizing the flow field distribution, improving the uniformity of the dispersion of the water-based coating, and reducing the problems of decreased gloss and adhesion of the paint film caused by uneven dispersion.

[0036] Furthermore, the barrel is truncated cone-shaped, with its radial dimension gradually narrowing away from the mounting ring 7-2.3. The angle between the generatrix of the truncated cone and the axis of the stirring shaft 7-1 is 15°~30°. This angle causes the water-based coating material to form an accelerated spiral downward flow on the inner wall of the barrel. Combined with the guide plate 7-2.1 and the guide groove 7-2.2, the suppression effect on vortices is further enhanced, and the dispersion efficiency is improved.

[0037] Furthermore, one end of the guide plate 7-2.1 is fixed to the inner ring wall of the lower end face of the barrel, and the other end extends upward along the inner ring wall to form an end, with a rounded corner away from the inner ring wall. The angle between the extension direction of the guide plate 7-2.1 and the radial plane of the control cover 7-2 is an acute angle, and the angle between the guide plate 7-2.1 and the radial plane of the control cover 7-2 is 20°~35°. When the stirring shaft 7-1 rotates, the axial thrust generated by the coating flowing along the upward guide plate 7-2.1 can drive the control cover 7-2 to move up and down along the axis of the stirring shaft 7-1. By dynamically changing the distance between the control cover 7-2 and the dispersion disk 7-3, the shearing and dispersion effect of the coating is enhanced.

[0038] Furthermore, the free end edge of the guide plate 7-2.1 on the side away from the inner ring wall is a smooth straight line segment, and the smooth straight line segment is connected to the end by a rounded corner transition. This rounded corner structure enables the coating to form a stable attachment vortex at the end of the guide plate 7-2.1. The rotation direction of the attachment vortex is consistent with the rotation direction of the stirring shaft 7-1, which suppresses the generation of turbulent vortex, reduces energy consumption, and strengthens the shearing effect between the coating and the dispersion disk 7-3.

[0039] Furthermore, the guide plate 7-2.1 has at least two protruding ridges 7-2.1.1 on the lower end face near the dispersion disk 7-3. The at least two protruding ridges 7-2.1.1 are distributed at intervals along the length of the guide plate 7-2.1, and the adjacent protruding ridges 7-2.1.1 form a guide channel. This structure enables the coating to form turbulent micro-vortices in the guide channel, further enhancing the dispersion effect of the vortex, improving the collision and fusion efficiency of pigments, resins and other components in the coating, and avoiding the impact of uneven dispersion on the gloss and adhesion of the paint film.

[0040] Furthermore, the mounting ring 7-2.3 has a pair of collinear through holes along the radial direction on its ring wall. The guide pin 7-4 is inserted into the two through holes. The inner ring wall of both through holes is provided with a limiting notch 7-2.3.1. The pin rod section of the guide pin 7-4 inserted into the through hole is provided with a positioning block 7-4.1 that cooperates with the limiting notch 7-2.3.1 to prevent the guide pin 7-4 from rotating and affecting the lifting and lowering of the control cover 7-2. The guide pin 7-4 includes a pin rod and a pin head, which are connected by threads.

[0041] Furthermore, the guide channel 7-2.2 is an waist-shaped channel located in the middle of the outer annular wall of the control cover 7-2. The angle between the extension direction of the guide channel 7-2.2 and the radial plane of the control cover 7-2 is an acute angle. The upper and lower ends of the guide channel 7-2.2 are respectively provided with rounded corners. The angle between the extension direction of the guide channel 7-2.2 and the radial plane of the control cover 7-2 is 30°~45°. This ratio allows the coating to form a laminar-turbulent transition flow field when passing through the guide channel 7-2.2. This, in conjunction with the spiral flow field of the guide plate 7-2.1, further optimizes the overall flow field distribution, reduces air entrainment, lowers the probability of coating bubble generation, and avoids defects such as pinholes and shrinkage cavities in the paint film.

[0042] Furthermore, at least four damping mechanisms 8 are distributed in a rectangular array on the lower end face of the base 1. Each damping mechanism 8 includes a mounting cylinder 8-1 that is perpendicularly fixed to the lower end face of the base 1 and a flexible rubber component 8-2 that is coaxially wrapped inside the mounting cylinder 8-1. The flexible rubber component 8-2 has a cavity coaxial with the mounting cylinder 8-1. The cavity is closed at the top and open at the bottom. A support seat 8-3 is inserted into the cavity. The support seat 8-3 includes a horizontally arranged base plate 8-3.1. The base plate 8-3.1 has an upwardly extending connecting column 8-3.2. In the assembled state, the base plate 8-3.1 abuts against the opening edge of the lower end of the flexible component 8-2, and the connecting column 8-3.2 is vertically inserted into the inner cavity. This structure can effectively absorb the vibration generated by suppressing vortices during the operation of the dispersion device, reduce equipment wear, ensure flow field stability, and avoid uneven coating dispersion caused by vibration.

[0043] Furthermore, the connecting column 8-3.2 includes a straight rod, and a spherical connector is integrally formed at one end of the straight rod away from the base plate 8-3.1. The top of the inner cavity of the flexible part 8-2 is provided with a hemispherical groove that mates with the spherical connector.

[0044] Furthermore, the rubber flexible component 8-2 includes a column and an internal cavity. The lower outer ring wall of the column is provided with an annular groove, and the inner wall of the mounting cylinder 8-1 is provided with a corresponding mounting boss. The upper part of the column and the outer side of the cavity are provided with an upward-opening annular swaying groove 8-2.1. The swaying groove 8-2.1 is located between the upper closed structure of the cavity and the top surface of the column. This structure reduces the shear stiffness of the rubber flexible component 8-2 in the horizontal direction, enhances the absorption capacity of lateral vibration, and, together with the spherical connector, further reduces the vibration transmission during the operation of the dispersion device, stabilizes the flow field distribution, ensures effective suppression of vortices, and improves the uniformity and stability of the dispersion of water-based coatings.

[0045] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
