Description

Technical Field

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

[0002] A coating disperser is a mixing machine used to stir and mix several raw materials. A high-speed rotating dispersing disc or blade impacts and shears the raw materials to dissolve, disperse, refine, and homogenize them. Highly efficient dispersers can reduce dispersion time, decrease the number of grinding passes, and improve production efficiency, thereby shortening the production cycle.

[0003] Most existing coating dispersion equipment mixes raw materials by rotating a dispersion disc. However, when producing organic powders and high-viscosity coatings, organic powders or highly viscous resins tend to accumulate around the cylinder, making it difficult to achieve thorough mixing of the coating. Furthermore, high-viscosity coatings require longer dispersion times during production, and manual cylinder cleaning is time-consuming and labor-intensive. Utility Model Content

[0004] In order to solve the above-mentioned technical problems, this utility model provides a high-speed disperser for the production of high-viscosity coatings, which can fully mix raw materials, reduce the dispersion time of coatings, improve dispersion efficiency, and reduce the unit production time of coatings.

[0005] This utility model is achieved by adopting the following technical solution.

[0006] A high-speed disperser for producing high-viscosity coatings includes a base, a support arm on the base, a telescopic arm inside the support arm, and a frame connected to the top of the telescopic arm. A wall-scraping drive motor is located at one end of the frame, and a driver is connected to the output end of the wall-scraping drive motor. The driver is connected via a drive belt to an output driver located at the other end of the frame. A wall-scraping stirring rod is internally connected to the output end of the output driver, and the lower end of the wall-scraping stirring rod is connected to the wall. A paddle stirring rod is located inside the wall-scraping stirring rod, with its upper end connected to the output end of a paddle driving motor, and paddles located at its lower part.

[0007] Furthermore, the scraper wall includes a coarse scraper wall and a fine scraper wall, with the end of the fine scraper wall movably inserted into the coarse scraper wall.

[0008] Furthermore, a groove is formed on the outer wall of the fine scraper wall, and a bolt is inserted through the coarse scraper wall. The bolt head is embedded in the groove to fix the relative position of the fine scraper wall and the coarse scraper wall.

[0009] Furthermore, the two end faces of the fine scraped wall are triangular prism structures.

[0010] Furthermore, the blades include upper blades and lower blades, and all blades have a serrated structure and are of the same size.

[0011] Furthermore, the upper and lower blades are connected to the agitator rod at opposite angles.

[0012] Furthermore, the blades of the upper and lower blades are arranged at a 120° angle between adjacent blades, and the blades of the upper blade are located in the middle of the two adjacent blades of the lower blade.

[0013] Furthermore, the support arm is equipped with a speed control device and an instrument panel, and the instrument panel is equipped with a tachometer to display the real-time speed of the wall scraping stirring rod and the paddle stirring rod, respectively.

[0014] This application has the following beneficial effects.

[0015] (1) This utility model is designed with a scraper wall, which includes two parts: a coarse scraper wall and a fine scraper wall. The fine scraper wall can extend and retract in the middle of the coarse scraper wall. The coarse and fine scraper walls are fixed by bolts and grooves. By extending and retracting the scraper wall, it can be used for production of different sizes of drawing cylinders. The two ends of the fine scraper wall are triangular pillar structures. The triangular pillars can not only scrape off the high-viscosity coatings that are stuck to the drawing cylinder wall, but also roll the organic powders that are difficult to disperse and accumulate around the drawing cylinder back into the drawing cylinder for stirring, so that the raw materials are more evenly dispersed.

[0016] (2) By setting up paddles, the paddles are divided into upper paddles and lower paddles, forming a sawtooth structure, and all paddle blades are the same size. This greatly increases the impact rate between the raw materials and the paddles, and improves the fineness of the powder. The upper and lower paddles are connected to the paddle stirring rod at opposite inclination angles, and the upper and lower paddle blades are distributed at a 120° angle to each other. The upper paddle blades are located in the middle of the lower paddle blades when viewed from above. This causes the upper and lower coatings to generate opposite motion states inside, increasing the disordered flow of raw materials in the mixing cylinder, thereby enabling the raw materials to be fully mixed.

[0021] The present patent application will be further described below with reference to the embodiments.

[0022] like Figure 1-3 As shown, a high-speed disperser for producing high-viscosity coatings includes a base 1, on which a support arm 2 is connected by a fixing device to prevent the support arm 2 from shaking.

[0023] The support arm 2 is equipped with two speed control devices 3 and an instrument panel 4 on its exterior. The speed control device 3 uses Almphenol's NB027240 component to control the speed of the wall scraping stirring rod 12 and the paddle stirring rod 13 by rotation. Each instrument panel 4 displays a tachometer to observe the speed of the wall scraping stirring rod 12 and the paddle stirring rod 13 in real time. The support arm 2 is equipped with an FH-GSD280201 speed sensor and an SJD series controller to detect the speed information and feed it back to the tachometer in the instrument panel 4.

[0024] The telescopic arm 5 is located in the middle of the support arm 2 and can extend and retract within the support arm 2 via an electric drive switch. A frame 9 is mounted on the support arm 2. One end of the frame 9 is equipped with a wall scraping drive motor 6, and a driver 7 is connected to the top of the wall scraping drive motor 6. The driver 7 has a solid internal structure. When the wall scraping drive motor 6 is turned on, the driver 7 moves clockwise, driving the drive belt 8, which in turn drives the output driver 10 connected to the other end to move. The output driver 10 has a hollow structure. A wall scraping stirring rod 12 is connected inside the output driver 10. This wall scraping stirring rod 12 has a hollow circular tube structure. A wall scraper 15 is welded to the lower end of the wall scraping stirring rod 12.

[0025] The scraper wall 15 is divided into two parts, coarse and fine. The fine scraper wall 153 can extend and retract between the coarse scraper wall 154. When the size of the cylinder scoring 16 is determined, the coarse and fine scraper walls are adjusted to the appropriate positions and fixed in place by bolts 151 and grooves 152. The two ends of the fine scraper wall 153 are triangular prism structures, which are hydraulically integrated with the scraper wall 15 to increase the durability of the outer side of the scraper wall. By setting up the scraper wall 15, the coating adhering to the cylinder scoring wall can be easily scraped off, making the raw materials mix more evenly.

[0026] A paddle drive motor 11 is located on the side of the frame 9 away from the wall scraping drive motor 6. It moves clockwise, in the same direction as the wall scraping drive motor 6. This clockwise rotation reduces the running resistance of the wall scraper 15, saving unnecessary energy consumption. The paddle drive motor 11 is connected to a paddle stirring rod 13, which is a solid structure and thinner than the wall scraping stirring rod 12. The paddle stirring rod 13 passes through the interior of the wall scraping stirring rod 12, and paddles 14 are fixedly connected to its bottom. The paddles 14 consist of an upper paddle 141 and a lower paddle 142, with a serrated structure. All paddle blades are the same size, and the upper and lower paddles are connected to the paddle stirring rod 13 at opposite angles. The upper and lower paddle blades are distributed at a 120° angle to each other, with the upper paddle 141 blade positioned between the lower paddle 142 blades when viewed from above. The effect achieved is to significantly increase the probability of material colliding with the blades, reduce the mixing time under the same degree of refinement, and at the same time greatly increase the disordered flow of the coating during mixing, so that the materials are mixed more evenly.

[0027] When using this device to mix materials, first place the equipment base 1 on a horizontal platform. Adjust the knob of the speed control device 3 according to the characteristics of the material to set the speed of the scraper drive motor 6 and the paddle drive motor 11. Place the scraper 15 and paddle 14 in the mixing cylinder 16, and put the material to be mixed into the mixing cylinder 16. After the power is turned on, the scraper drive motor 6 rotates, indirectly driving the scraper 15 to rotate via the drive belt 8; the paddle drive motor 11 drives the paddle 14 to rotate via the paddle stirring rod 13. Thus, the material in the mixing cylinder 16 is thoroughly and evenly mixed under the action of the scraper 15 and the paddle 14.

[0028] The embodiments described herein are preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape, and principle of this utility model should be included within the scope of protection of this utility model.
