Description

Technical Field

[0001] This utility model relates to the field of mixing and stirring technology, specifically a mixing device for chemical pigments. Background Technology

[0002] The production of chemical pigments is a crucial sector within the chemical industry, widely applied across various sectors. The uniformity of pigment mixing is fundamental to quality assurance, making the mixing device an indispensable and critical piece of equipment. It directly impacts pigment uniformity, color stability, and production efficiency. Currently, most traditional chemical pigment mixing devices on the market rely on mechanical stirring methods, such as paddle mixers and spiral mixers.

[0003] Currently, most coatings are prepared by mixing multiple solid or liquid materials. These materials are introduced into a mixing device, which then stirs and mixes them. Common mixing devices are typically barrel-shaped, with internal stirring mechanisms, such as impeller-type stirring mechanisms. However, these mechanisms have limitations on the amount of material, making it difficult for the impeller to fully contact the material, resulting in residues on the inner wall and affecting the mixing effect. Furthermore, the mixing process generates gas, impacting the production environment and worker health, requiring treatment. Therefore, a mixing device for chemical pigments is needed to solve these problems. Utility Model Content

[0027] Furthermore, the stirring assembly 51 includes a fixing plate 511, which is fixedly installed on the top of the stirring drum 2. A motor 512 is fixedly installed on the top of the fixing plate 511. The output shaft of the motor 512 extends into the interior of the stirring drum 2 and is fixedly installed with a protective shell 513. A gear A514 is fixedly installed at one end of the inner top of the stirring drum 2 extending into the interior of the protective shell 513. A gear B515 is rotatably installed on the inner top of the protective shell 513, and the gear B515 is meshed with the gear A514. A drive shaft 516 is fixedly installed at the bottom of the gear B515. A stirring blade 517 is fixedly installed at one end of the drive shaft 516 extending into the exterior of the protective shell 513, and the drive shaft 516 is rotatably connected to the bottom of the protective shell 513, which facilitates more thorough stirring by using dual stirring.

[0028] Furthermore, the cleaning component 52 includes a support plate 521, which is fixedly installed on the outside of the protective shell 513. A movable rod 522 is slidably installed on the end of the support plate 521 away from the protective shell 513. A scraper 523 is fixedly installed on the end of the movable rod 522 away from the support plate 521. A slide cylinder 524 is movably installed on the side of the support plate 521 close to the protective shell 513. A slide rod 526 is slidably installed inside the slide cylinder 524 and is movably connected to the movable rod 522. A spring 525 is fixedly installed between the slide cylinder 524 and the slide rod 526 to facilitate cleaning of the inner wall by rotation and prevent affecting the stirring efficiency.

[0029] Furthermore, the number of stirring blades 517 is multiple, and they are equidistantly and symmetrically distributed on the outside of the drive shaft 516 to facilitate thorough stirring.

[0030] Furthermore, there are two sets of scrapers 523, which are symmetrically distributed on both sides with the protective shell 513 as the axis, so as to facilitate thorough cleaning. Example

[0031] Please see Figure 5 Furthermore, in conjunction with Embodiment 1, the exhaust filtration mechanism 6 includes a mounting plate 61, which is fixedly installed on the outside of the mixing drum 2. A vacuum pump 62 is fixedly installed on the top of the mounting plate 61, and an air outlet 63 is provided on the outside of the vacuum pump 62. A filter box 64 is fixedly installed on the top of the mounting plate 61, and a filter plate 65 is slidably installed inside the filter box 64. A replacement plate 66 is fixedly installed on the side of the filter plate 65 away from the vacuum pump 62. A limit rod 67 is movably installed on the bottom of the filter box 64. A retaining plate 68 is fixedly installed on the outside of the replacement plate 66 near the limit rod 67, and the retaining plate 68 is slidably connected to the limit rod 67. A nut 69 is threadedly connected to the top of the limit rod 67. An air inlet pipe 610 is fixedly installed on the top of the filter box 64, and one end of the air inlet pipe 610 extends into the inside of the mixing drum 2 and is fixedly connected to the mixing drum 2 to facilitate the filtration of the gas generated by the mixing.

[0032] Furthermore, there are five sets of filter plates 65, which are evenly distributed inside the filter box 64 to improve the filtration effect.

[0033] In actual operation, when this device is used, the pigment to be stirred is first fed into the mixing drum 2 from the feed hopper 3. Then, the motor 512 is turned on, causing the output shaft of the motor 512 to drive the protective shell 513 inside the mixing drum 2 to rotate. When the protective shell 513 rotates, the gear B515 rotates around the gear A514 inside the protective shell 513. When the gear B515 rotates, it drives the stirring blade 517 on the lower transmission shaft 516 to rotate. Thus, while the protective shell 513 drives the transmission shaft 516 to rotate, the stirring blade 517 on the transmission shaft 516 also rotates simultaneously, which facilitates thorough stirring and accelerates the fusion of pigments. While the protective shell 513 rotates, the moving rod 522 on the support plate 521 drives the scraper 523 to scrape and clean the material on the inner wall of the mixing drum 2, passing through the slide cylinder 524. The sliding rod 526 on the side slides and compresses the spring 525, causing the moving rod 522 to slide inside the support plate 521, so that the scraper 523 can better fit the inside of the mixing drum 2, resulting in better cleaning effect. When the motor 512 is turned on, the mixing will generate gas. At this time, the air pump 62 is turned on, so that air can enter the mixing drum 2 from the air inlet 4. The gas inside the mixing drum 2 will enter the filter box 64 through the air inlet pipe 610, be filtered by the filter plate 65, and then be discharged through the air outlet 63 to prevent environmental pollution. When replacement is needed, the nut 69 can be rotated so that the nut 69 no longer fixes the limiting rod 67 to the clamping plate 68. Then, the limiting rod 67 is moved to both sides, and multiple sets of filter plates 65 are pulled out for replacement by pulling the replacement plate 66. Finally, the mixed pigment is discharged through the discharge port 7 for easy collection and treatment.
