Description

Technical Field

[0001] This specification relates to one or more embodiments in the field of water-based paint processing technology, and more particularly to a disperser for water-based paint processing. Background Technology

[0002] In the production and processing of water-based paints, the dispersion process is a key step that determines product quality. Its core is to use mechanical action to uniformly disperse solid particles such as pigments and fillers into the water-based medium to form a stable suspension system.

[0003] Existing dispersers typically use a single rotating blade to agitate and disperse materials. However, this method has several drawbacks in practical applications: Traditional blades only rotate, leading to a fixed flow field within the dispersion tank. This results in significant differences in the degree of dispersion at different heights and in different areas, particularly near the tank walls and bottom, where incomplete dispersion can occur, impacting final product quality. Furthermore, the single-dimensional agitation method has limited shear force on high-viscosity water-based paint raw materials, requiring extended dispersion time to achieve optimal results and hindering production efficiency. Moreover, existing equipment struggles to create vertical circulation of materials within the tank, causing solid particles to settle at the bottom, further exacerbating the uneven dispersion problem.

[0004] To address these issues, we designed a dispersant for water-based paint processing. Utility Model Content

[0005] In view of this, the purpose of this utility model is to propose a dispersing machine for water-based paint processing to solve the problem.

[0006] To achieve the above objectives, this utility model provides a disperser for water-based paint processing, comprising a disperser barrel and a barrel lid. A servo motor is installed at the center of the top of the barrel lid. A rotating rod is fixedly connected to the bottom drive shaft of the servo motor. The rotating rod is rotatably connected inside the servo motor. A sleeve is fitted on the outer wall of the rotating rod. A disperser blade is fixedly connected to the bottom of the sleeve. Connecting rods are symmetrically fixedly connected to the outer wall of the sleeve. A sliding block is fixedly connected to the end of the connecting rod away from the sleeve. A wave groove is formed on the inner wall of the disperser barrel, and the sliding block is slidably connected in the wave groove.

[0007] Furthermore, the peak of the waveform groove is located at the top of the dispersion barrel, and the trough of the waveform groove is located at the bottom of the dispersion barrel.

[0008] Furthermore, two limiting grooves are symmetrically provided on the outer side wall of the rotating rod, and limiting blocks are symmetrically fixedly connected to the inner side wall of the sleeve, with the limiting blocks slidably connected in the limiting grooves.

[0009] Furthermore, each of the two connecting rods is provided with a second dispersing blade, and the two second dispersing blades are respectively rotatably sleeved on the two connecting rods.

[0010] Furthermore, a feed inlet is fixedly inserted into one side of the top of the barrel lid, and a sealing cap is provided at the top of the feed inlet.

[0011] Furthermore, a discharge pipe is fixedly inserted into the bottom end of the dispersion tank, and a valve is installed on the discharge pipe.

[0012] As can be seen from the above, the beneficial effects provided by this utility model are:

[0013] 1. The sleeve drives the dispersing blade to achieve a compound action of "rotation + up and down reciprocating motion". With the trajectory design guided by the wave groove, the dispersing blade can cover different height areas inside the dispersing barrel, effectively eliminating the dispersing dead zone and solving the problem of uneven dispersion caused by the fixed flow field in traditional equipment.

[0014] 2. The combined motion of the first dispersing blade enhances the shear force and mixing range of the material, while the second dispersing blade rotates under the resistance of the material, forming multiple dispersing effects, which improves the dispersion efficiency of high-viscosity water-based paint raw materials and shortens the processing time.

[0015] 3. The reciprocating motion of the blades propels the material to form strong vertical convection within the dispersion tank, preventing solid particles from settling and ensuring that the raw materials are always in a dynamic mixing state during the dispersion process.

[0024] Please see Figures 1-4 This utility model provides a technical solution: a disperser for water-based paint processing, including a disperser barrel 1 and a barrel cover 2. A servo motor 3 is installed at the center of the top of the barrel cover 2. A rotating rod 4 is fixedly connected to the bottom drive shaft of the servo motor 3. The rotating rod 4 is rotatably connected inside the servo motor 3. A sleeve 5 is sleeved on the outer side wall of the rotating rod 4. A disperser blade 6 is fixedly connected to the bottom of the sleeve 5. A connecting rod 7 is symmetrically fixedly connected to the outer side wall of the sleeve 5. A sliding block 9 is fixedly connected to the end of the connecting rod 7 away from the sleeve 5. A wave groove 10 is opened on the inner side wall of the disperser barrel 1. The sliding block 9 is slidably connected in the wave groove 10.

[0025] See Figures 1-4 The peak of the wave groove 10 is located at the top of the dispersion barrel 1, and the trough of the wave groove 10 is located at the bottom of the dispersion barrel 1.

[0026] In practice, the servo motor 3 drives the rotating rod 4 to rotate. The rotational motion of the rotating rod 4 is transmitted to the sleeve 5 through the cooperation of the limiting block 12 and the limiting groove 11, causing the sleeve 5 to rotate together with the rotating rod 4. When the sleeve 5 rotates, the sliding block 9 connected to its outer wall via the connecting rod 7 slides within the corrugated groove 10 on the inner wall of the dispersion barrel 1. As the sleeve 5 rotates, the sliding block 9 reciprocates up and down along the trajectory of the corrugated groove 10, thereby driving the sleeve 5 to reciprocate up and down along the axial direction of the rotating rod 4 via the connecting rod 7. The rotational motion and the reciprocating motion of the sleeve 5 work together to act on the dispersing blade 6 at its bottom end, allowing the dispersing blade 6 to move up and down while rotating and dispersing the material, thus fully dispersing the material at different heights within the dispersion barrel 1.

[0027] See Figures 1-4 Two limiting grooves 11 are symmetrically opened on the outer side wall of the rotating rod 4, and limiting blocks 12 are symmetrically fixedly connected to the inner side wall of the sleeve 5. The limiting blocks 12 are slidably connected in the limiting grooves 11.

[0028] See Figures 1-4 Each of the two connecting rods 7 is provided with a second dispersing blade 8, and the two second dispersing blades 8 are respectively rotatably sleeved on the two connecting rods 7.

[0029] In specific implementation, based on the above implementation, the dispersing blade 8 rotatably mounted on the connecting rod 7 will rotate due to the resistance of the material as the connecting rod 7 rotates and moves up and down, further enhancing the shearing and dispersing effect on the material and improving the uniformity of dispersion.

[0030] See Figures 1-4 A feed inlet 13 is fixedly inserted into one side of the top of the barrel lid 2. A sealing cap is provided at the top of the feed inlet 13. A discharge pipe 14 is fixedly inserted into the bottom of the dispersion barrel 1. A valve is provided on the discharge pipe 14.

[0031] In practice, water-based paint raw materials are added to the dispersion tank 1 through the feed inlet 13. After dispersion, the water-based paint can be discharged from the dispersion tank 1 by opening the valve on the discharge pipe 14.

[0032] Working principle: When the disperser is working, the water-based paint raw material to be dispersed is first added into the dispersion tank 1 through the feed port 13, and the sealing cover is closed to ensure the processing environment is sealed.

[0033] Next, the servo motor 3 is started, and its drive shaft drives the rotating rod 4 to rotate. Since the sleeve 5 is slidably connected to the limiting groove 11 of the rotating rod 4 through the limiting block 12 on the inner side wall, the rotational motion of the rotating rod 4 is transmitted to the sleeve 5 through the cooperation of the limiting block 12 and the limiting groove 11, so that the sleeve 5 rotates together with the rotating rod 4. When the sleeve 5 rotates, the sliding block 9 connected to its outer side wall through the connecting rod 7 slides in the wave groove 10 on the inner side wall of the dispersing barrel 1. Since the crest of the wave groove 10 is located at the top of the dispersing barrel 1 and the trough is located at the bottom, the sliding block 9 will move up and down along the trajectory of the wave groove 10 while rotating with the sleeve 5, and then drive the sleeve 5 to move up and down along the axis of the rotating rod 4 through the connecting rod 7.

[0034] The rotational motion and reciprocating motion of the sleeve 5 work together on the dispersing blade 6 at its bottom, so that the dispersing blade 6 can move up and down while rotating to disperse the material, thus fully dispersing the material at different heights in the dispersing barrel 1.

[0035] Meanwhile, the dispersing blade 8, which is rotatably sleeved on the connecting rod 7, will rotate due to the resistance of the material as the connecting rod 7 rotates and moves up and down, further enhancing the shearing and dispersing effect on the material and improving the dispersion uniformity.

[0036] The bubbles generated during the dispersion process can be naturally discharged or broken through the structural design of the equipment. After dispersion, the water-based paint can be discharged from the dispersion tank 1 by opening the valve on the discharge pipe 14.
