[0026] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0027] A typical implementation of the present utility model is as follows Figure 1 As shown, a coating ultrasonic stirring device comprises a base 1 and a disperser, wherein the disperser is fixed on the base 1, and support legs 2 are arranged at the four corners of the bottom surface of the base 1, and each support leg 2 is composed of a retractable metal sleeve, and the support leg 2 comprises an outer tube 21 and an inner tube 22, wherein the outer tube 21 is sleeved on the outside of the inner tube 22, and the outer tube 21 and the inner tube 22 can slide relative to each other, and a plurality of fixing holes 23 are provided on the outer surfaces of the outer tube 21 and the inner tube 22, and the plurality of fixing holes on the outer tube 21 are arranged corresponding to the plurality of fixing holes on the inner tube 22, and bolts and nuts are arranged in the fixing holes 23 to realize a fixed connection between the outer tube 21 and the inner tube 22, thereby facilitating the adjustment of the height of the support leg 2.

[0028] By providing the retractable supporting legs 2, the height of the disperser can be adjusted according to the amount of the dispersed liquid to achieve the best dispersion effect.

[0029] The disperser includes a stirring disperser 3 and an ultrasonic disperser 4. The upper surface of the base 1 is provided with a plurality of tracks, such as Figure 2As shown, a plurality of tracks are arranged in parallel, the tracks are T-shaped, and the top and bottom surfaces of the tracks are both opened. The tracks include two stirring disperser tracks 5 and one ultrasonic disperser track 6. The two stirring disperser tracks 5 are respectively located on both sides of the ultrasonic disperser track 6. The stirring disperser track 5 is used to embed the stirring disperser 3 so that the stirring disperser 3 can slide along the track and be fixed on the track. The ultrasonic disperser track 6 is used to embed the ultrasonic disperser 4 so that the ultrasonic disperser 4 can slide along the track and be fixed on the track.

[0030] By setting the track, the position of the disperser can be adjusted as needed during the dispersion process to improve the dispersion efficiency and dispersion effect.

[0031] A locking block is provided on each track. The locking block is made of rubber and has a size larger than the track. Specifically, the locking block is a rectangular structure with a length of 5 to 6 cm, a width 1 to 2 mm larger than the track width, and a height 1 to 2 mm larger than the track depth. It can be embedded in the track and fixed by the friction between the track and the track. By setting the locking block, the disperser embedded in the track can be limited and fixed.

[0032] like Figure 3 As shown, there are four stirring and dispersing machines 3, which are symmetrically arranged in groups of two on two stirring and dispersing machine tracks 5, and a fastenable telescopic rod 7 is connected between the two stirring and dispersing machines 3 on the same track to maintain the position stability of the equipment during the stirring process.

[0033] Specifically, the fastenable telescopic rod 7 is formed by a sleeve of two round tubes with different diameters. The two round tubes can slide relative to each other. A fastening screw is provided at the tube mouth of the round tube with a larger diameter. By rotating the fastening screw, the tube mouth can be tightened, thereby pressing and fixing the round tube with a smaller diameter, thereby realizing the adjustment of the length of the fastenable telescopic rod 7.

[0034] like Figure 4 As shown, each stirring and dispersing machine 3 is equipped with an independent stirring motor 31 and a speed controller. The speed controller can adjust the running speed of the stirring motor 31 according to the viscosity of the dispersion liquid, and can stir at different positions of the track according to needs, while forming a stirring speed difference to improve the dispersion efficiency and effect.

[0035] The stirring motor 31 is located at the upper part of the stirring disperser 3, and a first hollow sleeve 32 is arranged below the stirring motor 31. First wear-resistant pulleys 33 are symmetrically arranged on both sides of the outer circumference of the first hollow sleeve 32. Specifically, first bolt holes are opened on both sides of the first hollow sleeve 32, and the first wear-resistant pulley 33 is fixed at the first bolt hole by bolts and nuts. The first wear-resistant pulley 33 adopts a metal wheel or a nylon wheel. The outer circumference of the first wear-resistant pulley 33 contacts the stirring disperser track 5, so as to facilitate the stirring disperser 3 to slide freely in the track.

[0036] The output shaft of the stirring motor 31 is fixedly connected to a stirring and dispersing rod 34, one end of which passes through the base 1 and is detachably connected to a dispersing disk 35. The dispersing disk 35 can be selected in different styles according to usage requirements, such as a gear type and a propeller blade type. The gear type dispersing disk can produce a shear effect on the dispersed liquid, thereby further improving its dispersing effect.

[0037] There is one ultrasonic disperser 4 , which is arranged on the ultrasonic disperser track 6 .

[0038] like Figure 5 As shown, the ultrasonic disperser 4 is equipped with an independent generator 41, and the generator 41 is externally connected to an independent power controller. Different ultrasonic powers can be changed through the power controller. The power can be adjusted specifically for different split slurries to improve the processing efficiency of powders and liquids.

[0039] The generator 41 is located at the upper part of the ultrasonic disperser 4, and a second hollow sleeve 42 is fixed below the generator 41. A second wear-resistant pulley 43 is symmetrically arranged on the outer surface of the second hollow sleeve 42. Specifically, second bolt holes are opened on both sides of the second hollow sleeve 42, and the second wear-resistant pulley 43 is fixed at the second bolt holes by bolts and nuts. The second wear-resistant pulley 43 contacts the side wall of the ultrasonic disperser track 6, thereby facilitating the ultrasonic disperser 4 to slide freely in the track.

[0040] The generator 41 is connected to the vibration probe 44. The vibration probe 44 is a multi-section structure. The diameter of each section of the vibration probe 44 is different. Different degrees of vibration frequency can be generated according to different coarseness and fineness, so as to achieve different dispersion effects for positions of different depths of liquid materials.

[0041] It also includes a dispersion cylinder 8, which is used to hold liquid materials. The dispersion cylinder 8 is located directly below the base 1, and the stirring head of the stirring disperser 3 and the probe of the ultrasonic disperser 4 are both inserted into the dispersion cylinder 8 to a position between one-third and two-thirds of the bottom of the cylinder; Figure 6 As shown, the dispersion cylinder 8 is made of 304 stainless steel, and the cylinder body is a double-layer hollow structure. A water inlet 81 is provided on the upper part of the cylinder body, and a water outlet 82 is provided on the lower part of the cylinder body. The water inlet 81 and the water outlet 82 are arranged diagonally. By connecting the water inlet 81 to cooling water, a cooling water circulation path is formed, thereby realizing the cooling effect on the cylinder body during the liquid dispersion process, thereby preventing the solvent in the dispersion liquid from volatilizing due to high temperature.

[0042] The bottom of the dispersion cylinder 8 is attached with an anti-skid layer 83, which is made of rubber. On the one hand, it increases the friction between the cylinder and the ground to prevent the cylinder from moving during the dispersion liquid treatment process, and on the other hand, it reduces the impact noise generated during the dispersion process.

[0043] The ultrasonic stirring device provided by the utility model can be used in high-speed mechanical stirring or ultrasonic dispersion or both at the same time or in alternating use of high-speed mechanical stirring and ultrasonic dispersion, which can effectively promote the full and uniform mixing of coatings and powder liquid materials, avoid filler agglomeration, and greatly improve the dispersion efficiency.

[0044] After use, the controller can be used to make the stirring and dispersing machine stir at low speed and the ultrasonic dispersing machine vibrate at low frequency, and use the dispersant used in the dispersion liquid to clean the inner wall of the cylinder, the stirring and dispersing head and the ultrasonic dispersing probe, so as to achieve all-round cleaning of the equipment and achieve the best cleaning effect.

[0045] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
