Description

Technical Field

[0001] The utility model relates to the field of dye mixers, in particular to a wall scraping device for dye mixers. Background Art

[0002] A mixer is a device that uses mechanical force and gravity to evenly mix two or more materials. The mixing process increases the contact surface area of the materials, promoting chemical reactions and accelerating physical changes. For example, during dye mixing, the mixed dyes adhere to the mixer's inner walls.

[0003] The existing scraping device has a scraper fixedly connected to the outside of the stirring shaft. The scraper is rotated to remove the dye adhering to the inner wall. However, as the use time increases, the edge of the scraper will rub against the inner wall and wear will occur, resulting in the scraper and the inner wall no longer fitting together, with a gap, which makes it easy for the dye to leak out.

[0004] Therefore, it is necessary to propose a new wall scraping device for dye mixer to solve the above problems. Utility Model Content

[0005] The purpose of the utility model is to provide a scraper device for a dye mixer to solve the problem that the existing scraper device is fixedly connected to the outer side of the stirring shaft, and the dye adhering to the inner wall is removed by rotating the scraper. However, as the use time increases, the edge of the scraper will rub against the inner wall and wear will occur, resulting in the scraper and the inner wall no longer fitting together, with a gap, which makes it easy to leak the scraped dye.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a wall scraping device for a dye mixer, comprising a mixing tank, a top cover is provided at the top of the mixing tank, a motor is fixed to the top of the top cover, a driving shaft at the bottom end of the motor is connected to a stirring shaft, a connecting rod is fixed to the outside of the stirring shaft, a rotating plate is rotatably connected to the outside of the connecting rod, a connecting plate is fixed to one end of the connecting rod, the connecting plates are distributed along the height direction of the mixing tank, and a scraper is telescopically provided on one side of the connecting plate close to the inner wall of the mixing tank, and one side of the scraper is attached to the inner wall of the mixing tank.

[0007] Preferably, the rotating plate is distributed along the length direction of the connecting rod, and a plurality of material supply holes are opened on the rotating plate. Both sides of the long side direction of the rotating plate are set as pointed ends, and the connecting plate and the rotating plate are distributed at right angles.

[0008] Preferably, a telescopic groove is provided on one side of the connecting plate close to the inner wall of the mixing tank, the telescopic groove is distributed along the height direction of the connecting plate, and a spring is fixed inside the telescopic groove, the scraper is fixedly connected to one end of the spring, and the scraper is telescopically arranged inside the telescopic groove.

[0009] Preferably, a water pipe is provided on one side of the top end of the top cover, the bottom end of the water pipe is connected to the interior of the mixing tank, and the bottom end of the water pipe corresponds to the top end of the scraper.

[0010] Preferably, a stirring toothed disc is fixed to the bottom end of the stirring shaft, and a plurality of stirring teeth are fixed to the outer ring of the stirring toothed disc. The plurality of stirring teeth are staggered up and down and distributed around the outer side of the stirring toothed disc.

[0011] Preferably, a conical discharge end is fixed to the bottom end of the mixing tank, and the conical tip of the conical discharge end faces downward.

[0012] Preferably, a discharge port is provided in the middle of the bottom end of the conical discharge end, and a control valve is provided on the discharge port.

[0013] The beneficial technical effects of the present utility model are:

[0014] When the stirring shaft rotates, it will synchronously drive the connecting plate and the scraper to rotate, stirring the raw materials inside. At the same time, since the scraper is attached to the inner wall of the mixing tank, it can scrape off the raw materials adhering to the inner wall during rotation, avoiding the problem of omission during discharge. Moreover, since the scraper is arranged inside the connecting plate by a spring, the elastic force of the spring can always keep the scraper attached to the inner wall of the mixing tank, avoiding the problem of friction and wear between the scraper and the inner wall after a long period of use, which leads to a gap between the scraper and the inner wall.

[0015] When the stirring shaft rotates, the rotating plate will come into contact with the raw materials inside. The rotating plate will be subjected to resistance and will rotate on the connecting rod. While reducing the resistance, the rotation of the rotating plate can flip the raw materials up and down, thereby speeding up the stirring and mixing efficiency. BRIEF DESCRIPTION OF THE DRAWINGS
