Description

Technical Field

[0001] The utility model relates to the field of mixing tanks, in particular to a mixing tank used for preparing leather auxiliaries. Background Art

[0002] Leather finishing agent is a general term for a class of leather auxiliaries used for leather surface finishing, protection and beautification. It is made of film-forming substances, coloring materials, solvents and auxiliaries in a certain proportion, among which film-forming substances are the basis of leather finishing agents. Leather finishing agents also play a very important role in the leather manufacturing industry. They can increase the beauty of leather, extend the use time of leather, significantly improve the quality and grade of leather products, and increase trade value. The mixing tank is a device that mixes leather auxiliaries with other agents;

[0003] A Chinese patent with publication number CN218358816U discloses a mixing tank. It includes a mixing bin and a feeding bin. The mixing bin is provided with a feed port on all sides. A screw feeder is detachably provided at the feed port. The opening above the screw feeder is provided with a feeding bin. It is characterized in that: a motor is provided above the mixing bin, a rotating rod is connected below the motor, the rotating rod vertically extends into the mixing bin, a spiral blade is provided at the lower part of the rotating rod to drive the bottom material upward, and a circular array of multiple stirring blades is provided at the extending end of the rotating rod; a discharge port is provided at the bottom of the mixing bin, and a discharge valve is provided at the discharge port. This device can transfer the bottom material upward through the spiral stirring blades, thereby realizing dual stirring in the vertical and horizontal directions.

[0004] When the stirring blades in the mixing tank of the above-mentioned patent stir the materials, since the stirring blades rotate to stir the materials, a vortex will be generated in the materials. Due to the centrifugal force, the materials close to the inner wall of the mixing tank cannot be thrown out by the centrifugal force, but are firmly attached to the inner wall, and are mixed more slowly with the materials in the center of the vortex, resulting in incomplete mixing between the materials. Utility Model Content

[0005] The utility model aims to provide a mixing tank for the preparation of leather auxiliaries, wherein two hydraulic cylinder structures are arranged on the mixing tank, and the movable end of the hydraulic cylinder structure extends into the mixing tank, and a scraper with the same angle as the inner wall of the mixing tank is arranged on the movable end of the hydraulic cylinder structure. When a rotating motor drives the stirring blade to rotate and stir the material in the mixing tank, the movable end of the hydraulic cylinder structure extends until the scraper on the movable end of the hydraulic cylinder structure is tightly attached to the inner wall of the mixing tank, thereby destroying the originally regularly rotating vortex, so that the material tightly attached to the inner wall is again drawn into the vortex and fully mixed with other materials, thereby solving the problems raised in the above-mentioned background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a mixing tank for the preparation of leather auxiliaries, comprising a mixing tank, a dust cover is arranged at the upper end of the mixing tank, and also comprises a hydraulic cylinder structure, the hydraulic cylinder structure is arranged on the dust cover, the movable end of the hydraulic cylinder structure penetrates the dust cover and extends into the mixing tank, a scraper is arranged on the movable end of the hydraulic cylinder structure, a fixed block is arranged on the dust cover, a rotating motor is arranged on the fixed block, a stirring blade is arranged on the output end of the rotating motor, the stirring blade penetrates the dust cover and extends into the mixing tank, and a discharge pipe is arranged at the lower end of the mixing tank.

[0012] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0013] The utility model is provided with a hydraulic cylinder structure on the dust cover, the movable end of the hydraulic cylinder structure extends into the mixing tank, and a scraper is provided on the movable end of the hydraulic cylinder structure, the scraper has the same angle as the inner wall of the mixing tank and is close to the inner wall of the mixing tank. When the rotating motor drives the stirring blade to start rotating and stirring the material in the mixing tank, the material generates a vortex, and the movable end of the hydraulic cylinder structure extends, so that the scraper is closely attached to the inner wall to destroy the originally regularly rotating vortex, so that the material closely attached to the inner wall is again drawn into the vortex and fully mixed with other materials, effectively avoiding the problem that when the stirring blade in the existing mixing tank stirs the material, because the stirring blade is rotating to stir the material, the material will generate a vortex, and because of the centrifugal force, the material closely attached to the inner wall of the mixing tank cannot be thrown out by the centrifugal force, but is firmly attached to the inner wall, and is mixed slowly with the material in the center of the vortex, resulting in incomplete mixing between the materials.
