[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0017] This invention uses a vacuum cleaner to suck up dust from a mixing tank via a suction tube. The dust then enters a filter box through a connecting pipe. The filter screen inside the filter box effectively filters the dust, preventing it from entering the subsequent collection box and ensuring the dust removal effect.
[0018] The filter screen is slidably connected to a groove on the inner wall of the filter box via a slider, which facilitates filter screen replacement. When the filter screen is clogged or damaged, the box door can be easily opened for replacement, ensuring the continuous and efficient operation of the entire dust removal device.
[0019] Connecting pipe two guides the filtered air into the collection box, which collects the filtered dust and other impurities. The unidirectional airflow design of the entire system effectively prevents dust backflow and ensures a clean environment inside the mixing tank.
[0020] This invention uses a servo motor to drive a stirring shaft to rotate. Stirring blades fixedly connected to the surface of the stirring shaft stir and mix the materials in the mixing tank as the shaft rotates. This stirring method ensures thorough mixing and improves the uniformity of the mixture.
[0021] A scraper is fixedly connected to the surface of the mixing blades, and its surface contacts the inner wall of the mixing tank. During the mixing process, the scraper can scrape off the material adhering to the inner wall of the mixing tank, preventing material residue, ensuring full utilization of the material, and facilitating subsequent cleaning.
[0022] The filter plate, which is fixedly connected to the inner wall of the mixing tank, is located at the bottom of the stirring shaft. During the mixing process, the filter plate can perform preliminary filtration of the material to prevent large particles of impurities from entering the discharge pipe, thereby further improving the quality of the mixing.
