Description

Technical Field

[0001] The present invention relates to the technical field of color paste processing auxiliary equipment, and in particular to a color paste homogenizing equipment and a color paste production system. Background Art

[0002] Color paste is a product in which pigment or pigment and filler are dispersed in paint. There are oily color paste, resin color paste and water-based color paste. In the process of color paste processing, stirring, mixing, grinding, filtering, homogenization and other processes are often involved to finally obtain a color paste product with uniform texture. Among them, the high-intensity shearing action generally used in homogenization makes the various components in the color paste fully mixed so that the final product can achieve the purpose of uniform texture. In the prior art, a high-speed shearing machine is generally used to provide sufficient shearing force to make the color paste achieve the purpose of uniform texture. In the prior art, the high-speed shearing machine runs fast, but the single processing volume is small. When docking with the front-end production equipment, it is greatly affected by the flow rate, which limits the efficiency of the overall processing, and is therefore not suitable for larger-scale processing. Summary of the invention

[0003] In view of the deficiencies in the prior art, the present invention provides a color paste homogenizing device, which solves the problem that the shearing homogenizing device in the prior art has a minor impact on the overall production efficiency.

[0004] According to an embodiment of the present invention, a color paste homogenizing device includes a homogenizing box, on which a feed pipe and a discharge pipe connected at the upper and lower ends are fixedly connected respectively; a mounting plate is also fixedly connected to the homogenizing box to separate it into an upper chamber and a lower chamber, and a plurality of filter holes are arranged on the mounting plate; a plurality of first drive motors are also installed on the homogenizing box, and a plurality of stirring spirals driven by each first drive motor are arranged in the homogenizing box, and the stirring spirals are located in the upper chamber.

[0005] In the above embodiment, the homogenization box is divided into an upper chamber and a lower chamber by a mounting plate, and filter holes are arranged on the mounting plate. During operation, a plurality of stirring spirals operate synchronously, so that the material passes back and forth between the upper chamber and the lower chamber, thereby becoming uniform and achieving the purpose of homogenization. Finally, the material is discharged through a discharge pipe, and the processing volume can be larger at one time, so that more materials can be supplied to adapt to a larger processing flow rate, thereby solving the problem in the prior art that the shear homogenization equipment has a smaller impact on the overall production efficiency.

[0006] Furthermore, the stirring spiral includes a first mounting shaft connected to the first drive motor, and the first mounting shaft extends vertically and is rotatably connected to the mounting plate. The first mounting shaft is also fixedly connected to a first spiral blade and a second spiral blade. The upper chamber is also fixedly connected to a homogenizing plate located between the first spiral blade and the second spiral blade, and the first mounting shaft rotates through the homogenizing plate.

[0007] Furthermore, a second drive motor is fixedly installed on the homogenization box, and the second drive motor is connected to a second mounting shaft located in the upper chamber. The second mounting shaft rotates through the homogenization plate and is also rotationally connected to the mounting plate; the second mounting shaft is also fixedly connected to a third spiral blade and a fourth spiral blade respectively located above and below the homogenization plate.

[0008] Furthermore, the homogenization plate is provided with a plurality of homogenization holes surrounding the first mounting axis, and a plurality of through holes surrounding the second mounting axis. All the homogenization holes and through holes form a through area and a homogenization area on the homogenization plate respectively, and an inner convex structure is provided in the homogenization hole.

[0009] Furthermore, the inner convex structure includes a plurality of spikes, one end of which is fixed to the homogenization hole and the other end of which extends toward the center of the homogenization hole.

[0010] Further, the first spiral lobe is located above the second spiral lobe, the third spiral lobe is located above the fourth spiral lobe, and the upper end of the third spiral lobe is located above the first spiral.

[0011] Furthermore, the feed pipe is located at one side of the homogenization box, the second installation shaft is close to the feed pipe, and all the second installation shafts are arranged side by side.

[0012] According to an embodiment, a color paste production system including the color paste homogenizing device is also provided.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] The homogenization box can be made larger to set more first mounting shafts and stirring screws. Multiple stirring screws run synchronously, so that the material passes back and forth between the upper chamber and the lower chamber, thereby becoming uniform and achieving the purpose of homogenization. Finally, it is discharged through the discharge pipe. The processing volume at one time can be larger, so more materials can enter and adapt to a larger processing flow rate, solving the problem in the prior art that the shear homogenization equipment has a smaller impact on the overall production efficiency.

DETAILED DESCRIPTION

[0021] The technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0022] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the present invention.

[0023] In an exemplary embodiment, Figure 1 , 2 As shown, this embodiment provides a color paste homogenizing device, which includes a homogenizing box 1, on which are fixedly connected a feed pipe 2 and a discharge pipe 3 which are connected at the upper and lower ends respectively; a mounting plate 4 is also fixedly connected inside the homogenizing box 1 to separate it into an upper chamber 5 and a lower chamber 6, and a plurality of filter holes 7 are arranged on the mounting plate 4; a plurality of first drive motors 8 are also installed on the homogenizing box 1, and a plurality of stirring spirals which are respectively driven by each first drive motor 8 are arranged in the homogenizing box 1, and the stirring spirals are located in the upper chamber 5.

[0024] In the above embodiment, the homogenization box 1 is divided into an upper chamber 5 and a lower chamber 6 by a mounting plate 4, and a filter hole 7 is provided on the mounting plate 4. During operation, multiple stirring spirals operate synchronously, so that the material passes back and forth between the upper chamber 5 and the lower chamber 6, thereby becoming uniform and achieving the purpose of homogenization. Finally, the material is discharged through the discharge pipe 3, and the processing volume can be larger at one time, so that more materials can be supplied to adapt to a larger processing flow, which solves the problem that the shear homogenization equipment in the prior art has a small impact on the overall production efficiency; specifically, the material is introduced into the upper chamber 5 from the feed pipe 2 through the upstream equipment, and partially passes through the filter hole 7 to the lower chamber 6. When the material is submerged in the mounting plate 4, the first drive motor 8 is started, and the operation causes the stirring spiral to stir the material located above the mounting plate 4 up and down, and at the same time drive the material to pass between the mounting plates 4. After a period of time, the first drive motor 8 is turned off, and the discharge pipe 3 is opened to discharge the material. During the discharge process, the filter hole 7 on the mounting plate 4 can also block the part that has not been homogenized to a smaller particle size, thereby ensuring that the discharged part is a qualified product.

[0025] In another further embodiment, if Figure 1 As shown, a color paste production system including the color paste homogenizing device in the above scheme is provided, which can increase the production flow rate to produce a larger amount of color paste products at one time, and ultimately the production efficiency is improved compared with the prior art.

[0026] like Figure 1-3 As shown, in a further exemplary embodiment, the stirring screw includes a first mounting shaft 9 connected to the first drive motor 8, and the first mounting shaft 9 extends vertically and is rotatably connected to the mounting plate 4, and the first mounting shaft 9 is also fixedly connected to the first spiral blade 10 and the second spiral blade 11, and the upper chamber 5 is also fixedly connected to a homogenizing plate 12 located between the first spiral blade 10 and the second spiral blade 11, and the first mounting shaft 9 rotates through the homogenizing plate 12, and the homogenizing plate 12 further divides the upper chamber 5 into upper and lower parts. When the first drive motor 8 is running, it drives the first spiral and the second spiral, so that the material passes through the homogenizing plate 12 above and below. Plate 12, further, a second drive motor 13 is fixedly installed on the homogenization box 1, and the second drive motor 13 is connected to a second mounting shaft 14 located in the upper chamber 5, and the second mounting shaft 14 rotates through the homogenization plate 12 and is also rotatably connected to the mounting plate 4; the second mounting shaft 14 is also fixedly connected to a third spiral blade 15 and a fourth spiral blade 16 respectively located above and below the homogenization plate 12, and the second drive motor 13 also runs synchronously, so that the material passes through the homogenization plate 12 more frequently, and the repeated passing through the homogenization plate 12 makes the material become finer and more uniform faster, and finally passes through the filter hole 7 more smoothly.

[0027] In more detailed schemes, such as Figure 1-4As shown, the homogenizing plate 12 is provided with a plurality of homogenizing holes 17 surrounding the outside of the first mounting shaft 9, and is also provided with a plurality of through holes 18 surrounding the outside of the second mounting shaft 14. All the homogenizing holes 17 and the through holes 18 respectively form a through area and a homogenizing area on the homogenizing plate 12. An inner convex structure is provided in the homogenizing hole 17. The through hole 18 allows the material to pass through more smoothly, and the material encounters less resistance in the through hole 18. An inner convex structure is provided in the homogenizing hole 17. The inner convex structure includes a plurality of spikes 19 with one end fixed to the homogenizing hole 17 and the other end extending toward the center of the homogenizing hole 17. These spikes 19 occupy a part of the position, so that the material encounters greater resistance. At the same time, in the first spiral and the second spiral Under forced pushing (or pulling), the material passes through these spikes 19 structures, thereby being subjected to stronger shearing, and finally achieving the purpose of homogenization faster; in further detail, the first spiral blade 10 is located above the second spiral blade 11, the third spiral blade 15 is located above the fourth spiral blade 16, and the upper end of the third spiral blade 15 is located above the first spiral. At the same time, the feed pipe 2 is located on one side of the homogenization box 1, and the second mounting shaft 14 is close to the feed pipe 2. All the second mounting shafts 14 are arranged side by side with the second mounting shaft 14, so that when the first mounting shaft 9 and the second mounting shaft 14 rotate, the direction of the material when the first spiral, the second spiral, the third spiral and the fourth spiral are running can be adjusted according to Figure 1 The direction indicated by the middle arrow makes the material present a serpentine path as a whole, and the material can also pass through the upper and lower parts of the mounting plate 4, which ultimately makes the homogenization efficiency better.

[0028] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the present invention, which should be included in the scope of the claims of the present invention.
