Description

A high-speed disperser for the production of water-based composite coatings Technical Field

[0001] This utility model relates to the field of water-based composite coating production technology, and in particular to a high-speed disperser for water-based composite coating production. Background Technology

[0002] Water-based composite coatings use water as a solvent or dispersion medium, offering advantages such as environmental friendliness and safety, and are increasingly widely used in the coatings industry. The production process of water-based composite coatings requires the uniform dispersion of various pigments, fillers, and additives within a water-based resin matrix to obtain high-performance coating products.

[0003] Traditional dispersion equipment uses a motor to drive a dispersion disc to rotate at high speed, thereby shearing and dispersing the coating. However, for some high-viscosity, high-solids-content waterborne composite coatings, especially when processing large quantities of coatings, the position of the dispersion disc is relatively fixed. Although a certain shearing force is generated around it, the resulting flow field is limited. The shearing force on the material near the periphery and outside the dispersion disc is different, which leads to uneven material dispersion and makes it easy for local pigment agglomeration or insufficient dispersion to occur, affecting the quality and performance of the coating. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this utility model provides a high-speed disperser for the production of water-based composite coatings. It solves the technical problem that the relatively fixed position of the single dispersion disc in existing technologies leads to limited flow fields, resulting in uneven material dispersion and affecting the quality and performance of the coating. This invention achieves the goal of enhancing the circulation flow of the coating and ensuring sufficient material dispersion.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a high-speed disperser for the production of water-based composite coatings, comprising a coating tank placed on a base, an electric lifting machine installed on the base, a power component installed on the free end of the electric lifting machine, a dispersing shaft rotatably connected to the power component, a dispersing disc one installed on the dispersing shaft, an electromagnet installed on the top wall of a sliding hole opened at the bottom of the dispersing shaft, a spring installed at the bottom of the electromagnet, a piston slidably connected to the inner wall of the sliding hole at the bottom of the spring, and the center part of the piston being made of magnetic material, a telescopic rod slidably connected to the bottom opening of the sliding hole at the bottom of the piston, a dispersing disc two installed at the bottom of the telescopic rod, a centering mechanism for clamping and fixing the coating tank on the base, and a temperature control mechanism for controlling the temperature of the coating inside the coating tank on the coating tank.

[0006] A further improvement is that the sliding hole is filled with hydraulic oil, and the piston has multiple damping holes arranged in an array, with the damping holes having a tapered structure that is wider at the bottom and narrower at the top.

[0007] A further improvement is that the power assembly includes a housing mounted on the top of the electric lift, with pulleys mounted on both sides of the housing, a transmission belt connecting the two pulleys, a drive motor mounted at the bottom of the housing to drive the rear pulley to rotate, and a distribution shaft connected to the front pulley.

[0008] A further improvement is that a guide rod is installed at the bottom of the housing, a sleeve is fitted on the guide rod, and a fixing ring connected to the sleeve by a connecting rod is installed on the electric lift.

[0009] A further improvement is that a threaded rod is rotatably connected in the rotating hole on the base, and the threaded rod has positive and negative threads on its left and right sides respectively. The threaded rod is symmetrically threaded to the two sides, and threaded sliders are slidably connected to the inner walls of the guide grooves on the left and right sides of the base. The top of each threaded slider is equipped with an arc-shaped clamp. A stepper motor that drives the threaded rod to rotate is installed on the base.

[0010] A further improvement is that the temperature control mechanism includes a serpentine heat exchange hole inside the paint bucket, with an inlet pipe installed at the top of the serpentine heat exchange hole and an outlet pipe installed at the bottom. A temperature sensor is installed at the center of the bottom wall of the paint bucket to monitor the temperature of the paint inside the bucket in real time.

[0011] By means of the above technical solution, this utility model provides a high-speed disperser for the production of water-based composite coatings, which has at least the following beneficial effects:

[0012] 1. This utility model uses the rotation of the dispersion shaft to drive the first and second dispersion discs on it to stir and disperse the coating from the middle and bottom, forming a dual flow field region, which improves the efficiency and effect of stirring and dispersing.

[0013] 2. This utility model uses the cooperation between an electromagnet, a spring, and a piston to drive the second dispersing disc to bounce up and down. When the second dispersing disc bounces up, the paint below is sucked up. When the second dispersing disc moves down, it presses the paint above against the bottom of the paint bucket, so that the paint circulates up and down in the paint bucket and generates dynamic shear force, which can more effectively break up agglomerates and clumps in the paint, so that the paint can be more fully mixed and dispersed, and avoid uneven dispersion of the paint.

[0014] 3. This utility model uses the rotation of the threaded rod to drive the two threaded sliders on it to move relative to each other, thereby driving the arc-shaped clamping plate to move relative to each other and clamp and fix the paint bucket in the center of the base, thus completing the fixing and centering of the paint bucket, ensuring that the dispersing shaft and dispersing disc act on the center of the paint bucket, and better stirring and dispersing the paint.

[0015] 4. This utility model uses a temperature sensor to monitor the temperature of the paint in the paint bucket in real time, and connects hot or cold water through the inlet pipe. Depending on the situation, the hot or cold water is introduced into the serpentine heat exchange hole to heat or cool the paint in the paint bucket. Attached Figure Description

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Example 1

[0031] Based on the existing technology where the single dispersion disc is relatively fixed in position, the resulting flow field has limitations, which can lead to uneven material dispersion and affect the quality and performance of the coating. This embodiment provides a high-speed disperser for the production of water-based composite coatings. Please refer to Figures 1-5. This embodiment provides a high-speed disperser for the production of water-based composite coatings, which can enhance the circulation flow of the coating and enable the material to be fully dispersed. This high-speed disperser for producing water-based composite coatings includes a coating tank 2 placed on a base 1, an electric lift 3 installed on the base 1, a power assembly 4 installed at the free end of the electric lift 3, a dispersing shaft 5 rotatably connected to the power assembly 4, a dispersing disc 6 installed on the dispersing shaft 5, an electromagnet 7 installed on the top wall of a sliding hole at the bottom of the dispersing shaft 5, a spring 8 installed at the bottom of the electromagnet 7, a piston 9 slidably connected to the inner wall of the sliding hole at the bottom of the spring 8, and the center of the piston 9 being made of magnetic material, a telescopic rod 10 slidably connected to the bottom opening of the sliding hole at the bottom of the piston 9, a dispersing disc 11 installed at the bottom of the telescopic rod 10, a centering mechanism 12 for clamping and fixing the coating tank 2 on the base 1, and a temperature control mechanism 13 for controlling the temperature of the coating inside the coating tank 2 on the coating tank 2.

[0032] The power assembly 4 drives the dispersion shaft 5 to rotate, which in turn drives the dispersion disc 6 on it to rotate, thoroughly stirring and dispersing the paint in the paint bucket 2. During this process, the electromagnet 7 is intermittently energized, which intermittently generates a repulsive force between it and the piston 9. Under the elastic force of the spring 8, the piston 9 is pushed up and down along the sliding hole, which in turn drives the telescopic rod 10 and the dispersion disc 11 at its bottom to move up and down, stirring and dispersing the paint in the paint bucket 2. When the dispersion disc 11 bounces up, the paint below is sucked up, and when the dispersion disc 11 moves down, it presses the paint above back to the bottom of the paint bucket 2, so that the paint circulates up and down in the paint bucket 2. When the dispersion disc 11 bounces up and down, the relative speed and direction of its movement with the paint constantly change, and the shear force generated also changes accordingly. Through dynamic shear force, agglomerates and clumps in the paint can be broken up more effectively, so that the paint can be more fully mixed and dispersed, avoiding uneven dispersion of the paint.

[0033] To prevent the spring 8 from bouncing up and down rapidly and to make its up and down movement more stable, hydraulic oil is filled into the sliding hole in the device. Multiple damping holes are arrayed on the piston 9, and the damping holes are tapered structures that are wider at the bottom and narrower at the top. When the spring 8 pulls the piston 9 upward, the hydraulic oil flows through the tapered damping holes, thereby using the viscosity of the hydraulic oil to buffer and stabilize the tension of the spring 8, and to prevent the spring 8 from bouncing up rapidly and causing the dispersion disc 11 to bounce, which would lead to instability.

[0034] The power assembly 4 includes a housing 41 mounted on the top of the electric lift 3, with pulleys 42 mounted on both sides of the housing 41. A transmission belt 43 is connected between the two pulleys 42. A drive motor 44 is mounted at the bottom of the housing 41 to drive the rear pulley 42 to rotate. The dispersion shaft 5 is connected to the front pulley 42. The drive motor 44 drives the rear pulley 42 to rotate, which in turn drives the front pulley 42 to rotate through the transmission belt 43 on the two pulleys 42. This drives the dispersion shaft 5 to rotate, which in turn drives the first dispersion disc 6 and the second dispersion disc 11 to rotate and disperse the coating.

[0035] A guide rod 31 is installed at the bottom of the housing 41, and a sleeve 32 is fitted on the guide rod 31. A fixing ring 33 connected to the sleeve 32 by a connecting rod is installed on the electric lift 3. When the electric lift 3 drives the first dispersion disc 6 and the second dispersion disc 11 to move up and down, the guide rod 31 also slides in the sleeve 32, thereby improving the stability of the up and down movement.

[0036] Example 2

[0037] To prevent the rotating dispersion discs 6 and 11 from causing turbulence in the paint and impacting the paint bucket 2, thus causing it to tip over, the device, based on Embodiment 1 and as shown in Figures 1-5, also includes a dispersion shaft 5. A threaded rod 121 is rotatably connected to a rotating hole on the base 1, with positive and negative threads on both sides of the threaded rod 121. Threaded sliders 122 are symmetrically threaded on both sides of the threaded rod 121 and slidably connected to the inner walls of guide grooves on the left and right sides of the base 1. Arc-shaped clamping plates 123 are mounted on the top of each threaded slider 122. A stepper motor 124 is mounted on the base 1 to drive the threaded rod 121 to rotate. Starting the stepper motor 124 causes the threaded rod 121 to rotate, which in turn causes the two threaded sliders 122 to move relative to each other, thereby causing the arc-shaped clamping plates 123 to move relative to each other and clamp and fix the paint bucket 2 in the center of the base 1. This completes the fixing and centering of the paint bucket 2, ensuring that the dispersion shaft 5 and dispersion disc 11 act on the center of the paint bucket 2 for better mixing and dispersion of the paint.

[0038] Example 3

[0039] Since the temperature of the coating needs to be adjusted accordingly during the dispersion process depending on the additives, based on Example 2, as shown in Figures 1-5, the device is also equipped with a temperature control mechanism 13. The temperature control mechanism 13 includes a serpentine heat exchange hole 131 opened inside the coating tank 2, and an inlet pipe 132 is installed at the top of the serpentine heat exchange hole 131, and an outlet pipe 133 is installed at the bottom. A temperature sensor 134 is installed at the center of the bottom wall of the coating tank 2 to monitor the temperature of the coating in the tank in real time. The temperature sensor 134 monitors the temperature of the coating in the coating tank 2 in real time, and hot or cold water is connected through the inlet pipe 132. Hot or cold water is introduced into the serpentine heat exchange hole 131 as needed, thereby heating or cooling the coating in the coating tank 2.
