DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] Example: Reference Figure 1-5The mixing device for preparing activated carbon shown includes a mixing tank 1, and a stirring mechanism is installed on the inner side of the mixing tank 1, wherein a feed port and a discharge port are respectively provided at the upper and lower ends of the mixing tank 1, and a dust cover 2 and a sealing cover 3 are respectively detachably installed at the feed port and the discharge port.

[0029] Among them, the stirring mechanism includes a driving motor 4 and a stirring assembly 5, the driving motor 4 is fixed on the outer wall of the mixing tank 1, the stirring assembly 5 is rotatably installed on the inner side of the mixing tank 1, and one end of the stirring assembly 5 is coaxially fixed with the output end of the driving motor 4, and a mounting base 6 is provided on the lower side of the mixing tank 1, and one side of the upper end of the mounting base 6 is rotatably connected to one side of the bottom end of the mixing tank 1 through a rotating connecting piece 7, wherein the rotating connecting piece 7 is a conventional rotating connection structure in the prior art and no detailed description is needed here. The other end of the stirring assembly 5 passes through the mixing tank 1 and is connected to a cam 11, and a limit seat 8 that abuts against the bottom end of the cam 11 is installed at the end of the mounting base 6 away from the rotating connecting piece 7.

[0030] The driving motor 4 drives the stirring component 5 to rotate. While the rotating stirring component 5 stirs and mixes the materials inside the mixing tank 1, the cam 11 is used to rotate synchronously with the stirring component 5, so that the mixing tank 1 is continuously shaken, so that the materials inside the mixing tank 1 are mixed better, and there is no need to add other electrical equipment, which is more energy-saving.

[0031] Regarding the stirring assembly 5, specifically, the stirring assembly 5 includes a rotating shaft 51, a mixing rod 52 and a scraper 53. The rotating shaft 51 is rotatably installed on the inner side of the mixing tank 1, and the two ends of the stirring assembly 5 are respectively connected to the output end of the driving motor 4 and the cam 11. There are multiple mixing rods 52 and scrapers 53 correspondingly arranged. The multiple mixing rods 52 are evenly fixed along the length direction of the rotating shaft 51. The scraper 53 is fixed to the end of the mixing rod 52 away from the rotating shaft 51, and slides in contact with the inner wall of the mixing tank 1.

[0032] The driving motor 4 drives the rotating shaft 51 to rotate with the mixing rod 52 and the scraper 53. The rotating mixing rod 52 stirs and mixes the materials inside the mixing tank 1, and the rotating scraper 53 scrapes off the materials adhered to the inner wall of the mixing tank 1.
