Description

Technical Field

[0001] The invention relates to the technical field of water-in-water multi-color coatings, and in particular to a fine granulation device for water-in-water artistic coatings. Background Art

[0002] With the increasing requirements for environmental protection of building materials, water-in-water multi-color coatings have emerged on the market, gradually replacing oil-in-oil system, oil-in-water system, and water-in-oil system coatings on the market. Since the quality and various properties of water-in-water coatings are closely related to the particle size of color dots, the granulation stage of color dots is particularly important.

[0003] At present, the granulation of water-in-water multi-color coating products is basically carried out by extruding the color dots with a mesh propeller blade, and the particle size of the color dots is mainly controlled by selecting the size of the mesh aperture. However, the mesh propeller blade extrusion granulator needs to extrude the continuous phase and the dispersed phase through the mesh aperture to obtain the color dots, which usually results in the particle size of the color dots obtained by granulation being actually larger than the mesh aperture size. Therefore, in order to ensure the uniformity of the particle size of the color dots, it is generally necessary to perform secondary granulation on the color dots, resulting in extremely low efficiency of the color dot granulation. More importantly, when the existing mesh propeller blade extrusion granulator is used to granulate the color dots with a particle size less than 3 mm, the granulation efficiency will be greatly reduced. If you want to obtain color dots with a particle size less than 1.5 mm, even if you use a mesh granulation with a mesh size of 1.5 mm, the color dots will have a particle size greater than 3 mm. And if you want to obtain a number of color dots with a particle size of 1.5 mm greater than 95%, the existing mesh propeller blade extrusion granulator cannot achieve this requirement at all.

[0004] At present, there are still a few people who directly use the dispersing blades used for color dot base materials for color dot granulation. In this way, not only can the color dots with good uniformity and particle size less than 3mm not be obtained, but the dispersing blades are also easy to hit the color dots into irregular fragments or even cause the color dots to become a paste during the granulation process. The particle size uniformity of the color dots obtained by granulating the color dots in this way is extremely poor, and some color dots are still irregular in shape, which seriously affects the adhesion, anti-fouling and wear resistance of the material and other various properties as well as the aesthetics of the coating; even the color dots are hit into a paste and cannot be further synthesized into water-in-water multi-color coatings. Summary of the invention

[0005] In view of the above-mentioned deficiencies in the prior art, the present invention provides a water-in-water artistic paint fine granulation device, which aims to solve the technical problems that the existing water-in-water paint granulator cannot efficiently and large-scale granulate color dots with good uniformity and particle size less than 3mm.

[0006] In view of the above technical problems, the technical solution adopted by the present invention to solve the technical problems is:

[0007] A fine granulation device for water-in-water artistic paint includes a high-speed power mechanism, a transmission shaft is fixed to the power output end of the high-speed power mechanism, a granulation mechanism is arranged at the other end of the transmission shaft, the granulation mechanism includes a dispersion disk with a curved surface structure on the outer surface, at least two dispersion leaves for color dot granulation are evenly arranged on the side walls around the dispersion disk, and the dispersion leaves are provided with knife edges on the front side walls along the length extension direction, and the angle between the outer side walls of the knife edges is less than 90°.

[0008] Preferably, the knife edge is arranged at the upper middle portion of the front side wall or the rear side wall of the dispersion blade, and the top surface and the bottom surface of the dispersion blade extending along the length direction are both in an arc-shaped structure. The structure of the dispersing leaf is arranged in this way so that the curved surface structure of the top surface of the dispersing leaf is relatively gentle, and the curved surface structure of the bottom surface of the dispersing leaf has a larger curvature. In this way, except for the cutting and granulation of the color base material and the protective glue with the blade, the other parts of the dispersing leaf are in soft curved contact with the color base material and the protective glue. On the one hand, it prevents the dispersing leaf from causing excessive impact on the color base material and the protective glue, avoids the serious unevenness of the color dot particles, and ensures the good uniformity of the color dots after granulation and the better stability of the color dots after granulation; on the other hand, it enables the color base material to be quickly and evenly coated by the protective glue on the curved surface of the bottom of the dispersing leaf after being cut into particles, so as to ensure the granulation efficiency and uniformity, and then the curved surface of the bottom of the dispersing leaf quickly applies an oblique downward thrust to the granulated color dots, so that the color dots can be quickly detached from the dispersing leaf, avoid the adhesion of the color base material to the blade, and the color dots after granulation move obliquely downward, so as to avoid excessive granulation of the granulated color dots; and in this way, it ensures that the blade is always sharp, so that the granulation effect of the color dots is excellent.

[0009] Preferably, the front and rear side walls of the dispersing leaf extending along the length direction are both provided with blades, and the free end of the dispersing leaf is provided with a rounded structure, so that the rounded structure is provided to avoid the formation of turbulence and excessive impact between the color base material and the protective glue. This arrangement makes the torsion of the dispersing leaf large, which ensures that the dispersing disk can meet the requirements of the particle size of the color dot granulation while ensuring that the strength performance of the dispersing leaf reaches the best; in this way, the blades on both sides of the dispersing leaf can be used for granulation. When the dispersing leaf rotates, one blade is used for color dot granulation, and the other blade can avoid the formation of tail flow when the dispersing leaf rotates, and avoid the continuous formation of a large number of bubbles in the color base material and the protective glue, further ensuring the quality and stability of the color dot granulation.

[0010] Preferably, the dispersion disk and the transmission shaft are detachably arranged, and the dispersion leaves and the dispersion disk are detachably arranged. By arranging the dispersion disk in this way, on the one hand, when the dispersion leaves and the dispersion disk are worn and damaged, the specific dispersion leaves and specific parts on the base that are worn and damaged can be repaired and replaced in time, so that the blades of the dispersion leaves can be checked at any time for wear and replaced in time, and the entire granulation mechanism does not need to be replaced, which can effectively ensure the effect of color dot granulation and make the use and maintenance costs of the granulation device extremely low; more importantly, on the other hand, due to the consistency of the color base material and the protective glue, and the batch size of each granulation will be different, it is necessary to replace the entire granulation mechanism or use a different granulator, which will cause the equipment cost to increase exponentially. The present invention is arranged in this way to meet the requirements of various consistencies and batch sizes of color dot granulation by adjusting the installation angle of the dispersion leaves or directly replacing different dispersion leaves, and the particle size of the color dot granulation can meet the requirements of less than 3mm.

[0011] Preferably, the dispersion disk is in an ellipsoidal structure. The dispersion disk is arranged in this way in the present invention to reduce the contact and adhesion between the dispersion disk and the dispersed phase and the continuous phase color base and protective glue, and also reduce the vertical impact of the dispersion disk on the color base and protective glue, ensuring that the fluid of the entire color base and protective glue can flow smoothly and avoid turbulence; avoiding the granulation process from affecting the stability of the completed color dots, and also preventing the color base and protective glue fluid from forming vortices during the granulation process, resulting in serious uneven particle size of the color dots obtained by granulation; more importantly, the structure of the dispersion disk is arranged in this way so that after the color base and protective glue are dispersed and granulated, the color base can be evenly coated by the protective glue on the outer surface of the dispersion disk with a curved structure, which significantly improves the efficiency of color dot granulation and makes the particle size of the granulated color dots more uniform.

[0012] Preferably, the dispersion disk includes a base, and a plurality of mounting structures for mounting dispersion leaves are evenly arranged near the outer side wall of the base. A first matching hole for fixed installation with a transmission shaft is arranged at the center position of the base. Such an arrangement can meet the granulation requirements while ensuring that the installation, disassembly and maintenance operations between the dispersion disk and the transmission shaft, and between the dispersion disk and the dispersion leaves are more convenient.

[0013] Preferably, the mounting structure includes a horizontal mounting hole and a vertical fixing hole, the horizontal mounting hole is arranged on the side wall of the outer edge of the base, the vertical fixing hole is arranged near the top of the base, and the vertical fixing hole is connected to the horizontal mounting hole, and the fixed end of the dispersion leaf is fixed to the base at an adjustable angle through the horizontal mounting hole, the vertical fixing hole and the inclination locking nut. Such an arrangement not only makes it convenient to fix and install the dispersion leaves, but also prevents the dispersion leaves from positional displacement during long-term operation after being fixed, and the entire dispersion disk can maintain stable performance, thereby ensuring the effect of color dot granulation; in addition, the dispersion leaves are fixedly installed by means of the inclined locking nut, so that the angle of the dispersion leaves can be adjusted according to different production conditions, so that the present invention can meet the production requirements of color dot granulation of tinting base materials and protective glues with different batches and consistencies, and has a very wide range of applications; for example, when the consistency of the tinting base material and the protective glue is relatively small and the batch size is small, the angle between the dispersion leaves and the horizontal plane is adjusted to be relatively small, thereby selecting a relatively small motor speed, so that the color dot granulation of the coating can be achieved; when the consistency of the tinting base material and the protective glue is relatively large and the batch size is large, the angle between the dispersion leaves and the horizontal plane is adjusted to be relatively large, thereby selecting a relatively large motor speed, so that the color dot granulation of the coating can be achieved;

[0014] Preferably, the dispersion disk also includes a cover plate, which includes two semicircular cover plates, a second matching hole matching the transmission shaft is arranged at the center position of the cover plate, the cover plate is fixed to the top of the base by a countersunk cover plate nut, and the base, the cover plate and the transmission shaft are fixedly connected by a fixing nut; in the present invention, two semicircular cover plates are arranged, so that the cover plates are extremely convenient to remove, a larger inclined locking nut can be arranged and used, and there is a gap between the top of the inclined locking nut and the base to ensure the locking of the dispersion leaves, and the cover plate can effectively protect the inclined locking nut from direct contact with the material, so as to avoid the inclined locking nut being contaminated by the material and affecting the maintenance, and also to avoid the inclined locking nut During the color dot granulation process, the master nut collides with the color base material and the protective glue in high-speed flow, which seriously affects the granulation quality. The stability of the dispersion leaf fixation can also be ensured. In addition, the collision of the inclined locking nut with the color base material and the protective glue can be avoided to avoid damage to the color base material and the protective glue, prevent serious uneven color dot granulation and the appearance of a pasty structure in the raw materials, and prevent the raw materials from forming turbulence and seriously affecting the uniformity of color dot granulation. In the present invention, the base, the two semicircular cover plates and the transmission shaft can be directly fixedly connected by the fixing nut, so that the fixing structure and the fixing method are the simplest while meeting the connection strength requirement, and such installation will not bring adverse effects to the granulation process.

[0015] Preferably, a positioning structure is provided at the connection between the base and the transmission shaft, and a sealing structure is provided between the base and the cover plate. The positioning structure is provided in the present invention so that the base, the cover plate and the rotating shaft can maintain a synchronous rotation state in the horizontal direction for a long time. During the high-speed rotation granulation process of the granulation mechanism, it is ensured that the rotating shaft and the base will not rotate asynchronously, so that the rotating shaft can drive the dispersion disk to rotate synchronously, avoiding power loss and ensuring the efficiency of color dot granulation. The sealing structure is provided between the base and the cover plate in the present invention on the one hand to ensure that the base and the cover plate can be closely matched, and to prevent the color base material and the protective glue from entering the gap between the base and the cover plate, so that the base, the cover plate and the inclined locking nut and other components can be closely protected; more importantly, this can prevent the gap between the cover plate and the base from being bonded and blocked, and the base and the cover plate can be quickly disassembled and repaired and installed, and the color base material and the protective glue will not enter the gap between the base and the cover plate and bond, so as to avoid the difficulty of disassembling the cover plate and the base.

[0016] Preferably, the high-speed power mechanism includes a motor, and the motor has a working speed of 200 to 950 r / min. The present invention selects the motor speed so that the dispersing blades in the present invention can ensure that the color dots obtained by granulating different batches and different consistencies of the color base materials and protective glues meet the granulation requirements of a particle size of less than 3 mm; at the same time, avoid the occurrence of the color dots with too large particle size, irregular color dots, and too small particle size; more importantly, it can ensure that the color base material remains in a stable state after granulation in the protective glue, avoid the color base material and the protective glue from being in a pasty state, and ensure a good granulation effect of the color dots.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] The present invention ingeniously designs the color dot granulator of the entire coating, designs and assembles the dispersion disk and the dispersion blades in the granulation structure, so that the present invention only needs to perform granulation once to achieve the granulation requirement that the color dot particle size is less than 3mm, and no matter the consistency of the color base material and the protective glue, and the batch size, the present invention can complete the granulation requirement that the color dot particle size is less than 3mm within 10 minutes, and the proportion of the color dot particle size less than 3mm after granulation reaches more than 99%. The present invention realizes efficient and large-scale granulation of the color base material and the protective glue, and no irregularity or paste structure will appear in the color dot granulation process, and the color dot fineness and uniformity obtained by the color dot granulation are excellent; thus, the finally prepared water-in-water art mud coating has better aesthetics and artistic sense, and lower processing and manufacturing cost; and the distribution of the color dots on the formed wall is more delicate and uniform, the coating has stronger covering ability on the wall, and can be sprayed on the wall at one time, so that the coating per square consumption is lower.

[0024] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the following will be described clearly and completely in combination with the technical solution in the embodiments of the present invention. Obviously, the described embodiments are partial embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work belong to the protection scope of the present invention.

[0025] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the invention claimed for protection, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0026] The terms “first”, “second”, “third”, etc. are only used for distinguishing descriptions and should not be understood as indicating or implying relative importance.

[0027] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be the internal communication of two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0028] A water-in-water art paint fine granulation device according to a preferred embodiment of the present invention is shown in the attached Figure 1 , including a high-speed power mechanism 1, a transmission shaft 2 is fixed at the power output end of the high-speed power mechanism 1, a granulation mechanism is arranged at the other end of the transmission shaft 2, the granulation mechanism includes a dispersion plate 3 with a curved outer surface structure, at least two dispersion leaves 4 for color dot granulation are evenly arranged on the side walls around the dispersion plate 3, and a knife edge 5 is arranged on the front side wall or the rear side wall along the length extension direction of the dispersion leaf 4, and the angle between the outer side walls of the knife edge 5 is less than 90°.

[0029] In specific implementation, the present invention can be directly installed on the bracket 6 to granulate the color base material and protective glue in the container. The granulation mechanism in the present invention can be installed in a stirring tank (not shown in the figure), and the high-speed power mechanism 1 is installed in the stirring tank for granulation, etc.

[0030] For specific implementation, please refer to the attached Figure 3 The blade 5 is arranged at the middle and upper part of the front side wall or the rear side wall of the dispersion leaf 4, and the top and bottom surfaces of the dispersion leaf 4 extending along the length direction are both in an arc-shaped structure. In this way, the curved surface structure of the top surface of the dispersion leaf 4 is relatively gentle, and the curved surface structure of the bottom surface of the dispersion leaf 4 has a larger arc, which avoids excessive impact on the color base material and the protective glue, and can quickly complete the color dot granulation, and quickly separate the color dots from the dispersion leaf 4 and move downward into a large circulation, so as to avoid the color dot granulation from entering the dispersion leaf tail flow for repeated granulation after the color dot granulation is completed. In addition, it can prevent the color base material and the protective glue from adhering to the blade 5 of the dispersion leaf 4, and avoid the blade 5 from being blunted, so that the blade 5 can always remain sharp, ensuring the excellent color dot granulation effect.

[0031] For specific implementation, please refer to the attached Figure 4 The front and rear side walls of the dispersing blade 4 extending along the length direction are both provided with a knife edge 5, and the free end of the dispersing blade 4 is provided with a rounded structure. The knife edges 5 on the front and rear side walls of the dispersing blade can be provided with the same structure or different structures, so that the rotation direction of the dispersing disk 3 is directly changed, and the angle of the dispersing blade 4 is changed, so that color base materials and protective glues of various consistencies and raw materials of different batches can be granulated with color dots without replacing other dispersing blades 4 with different knife edges 5.

[0032] In specific implementation, the dispersion leaves 4 can be welded to the dispersion disk 3, and the dispersion disk 3 can be welded to the transmission shaft 2. A better way is that the dispersion disk 3 and the transmission shaft 2 are detachable, and the dispersion leaves 4 and the dispersion disk 3 are detachable; this allows the dispersion leaves 4 to be adjusted and replaced more quickly according to different production conditions of the color dot granulation or when the granulation mechanism is damaged.

[0033] In specific implementation, the dispersion disk 3 has an ellipsoidal structure. In this way, under the premise of meeting the granulation strength performance, the dispersion disk 3 and the color base material and the protective glue will not collide with each other except the blade 5, so that the uniformity and stability of the color dot granulation are better.

[0034] For specific implementation, please refer to the attached Figure 2 The dispersion disk 3 includes a base 7, and a plurality of mounting structures for mounting dispersion leaves 4 are evenly arranged near the outer side wall of the base 7. The dispersion leaves 4 are optimally arranged to have 2 to 8 pieces, so that the color dot granulation efficiency is optimal and the granulation effect is best; a first matching hole 14 for fixed installation with the transmission shaft 2 is arranged at the center position of the base 7.

[0035] In specific implementation, the mounting structure includes a horizontal mounting hole 10 and a vertical fixing hole 11. The horizontal mounting hole 10 is set on the side wall of the outer edge of the base 7, and the vertical fixing hole 11 is set at the base 7 near the top of the horizontal mounting hole, and the vertical fixing hole 11 is connected with the horizontal mounting hole 10. The dispersion leaf 4 is fixed on the base 7 at an adjustable angle through the horizontal mounting hole 10, the vertical fixing hole 11 and the slope locking nut 12. The fixed end of the dispersion leaf 4 is set in the shape of a connecting rod, and the middle part of the connecting rod is provided with a thread to cooperate with the horizontal mounting hole 10. The dispersion leaf 4 is installed in the horizontal mounting hole 10 according to the required angle, and then the fixed end of the dispersion leaf 4 is pressed and fixed by the slope locking nut 12 to ensure the stability of the dispersion leaf 4 after fixation.

[0036] In specific implementation, the dispersion disk 3 also includes a cover plate 13, and a second matching hole 8 for fixing with the transmission shaft 2 is set at the center of the cover plate 13. The cover plate 13 is fixed to the top of the base 7 through a countersunk cover plate nut 15, and the base 7, the cover plate 13 and the transmission shaft 2 are fixedly connected through a fixing nut 16. The cover plate 13 can be set to be formed by splicing and fixing two semicircular cover plates 13 to form the cover plate 13, and the countersunk cover plate nut 15 is fixed close to the transmission shaft 2, so that the top surface of the granulation mechanism has a smooth arc structure, ensuring that the fluid of the entire color base material and the protective glue can flow smoothly. When adjusting and repairing the dispersion leaf 4, it is not necessary to disassemble the entire dispersion disk 3, and only the cover plate 13 needs to be removed to repair the dispersion leaf 4 and adjust the inclination; in addition, such a configuration makes it difficult for the cover plate 13 to adhere to the base 7, which is convenient for disassembly.

[0037] During specific implementation, a positioning structure 17 is provided at the connection between the base 7 and the transmission shaft 2. The positioning structure 17 is a groove correspondingly provided on the top surface of the base 7 and the bottom surface of the transmission shaft 2, and a positioning steel ball is provided in the groove; a sealing structure 18 is provided between the base 7 and the cover plate 13. The sealing structure 18 is a sealing rubber pad, and a positioning protrusion is also provided on the sealing rubber pad, so that the installation of the sealing rubber pad is more convenient.

[0038] In specific implementation, the high-speed power mechanism 1 includes a motor, and the transmission shaft driven by the motor has a rotation speed of 200 to 950 r / min when working. The rotation speed of the motor is selected according to the consistency of the color base material and the protective glue and the batch size of the raw materials to achieve excellent color dot granulation effect, granulation efficiency and granulation quality. The rotation speed of the motor and the granulation mechanism can achieve granulation of color dots with a particle size of less than 3 mm, and the particle size of color dots with a particle size of less than 3 mm is smaller and more uniform; it also avoids the situation where the granulation mechanism only mixes the raw materials or the granulation is excessively impacted and becomes a paste.

[0039] It should be understood that those skilled in the art can make improvements or changes based on the above description, and all these improvements and changes should fall within the scope of protection of the appended claims of the present invention.
