Mixing barrel with water flushing scraper blade for chemical use

Abstract

The invention relates to a mixing barrel with a water flushing scraper blade for chemical use. The mixing barrel comprises a mixing barrel, and a stirring shaft arranged inside the mixing barrel, wherein the mixing shaft is of a barrel-shaped structure with a central through hole, the upper end of the stirring shaft is provided with an opening, the lower end of the stirring shaft is fixedly connected with a belt pulley, the upper end surface of the mixing barrel is fixedly connected with a water inlet pipe, the water inlet pipe extends into the central through hole of the stirring shaft and is connected with an external water supply, a cylinder is arranged on the lower surface of the belt pulley, a piston rod of the cylinder is fixedly connected with a mandril, the mandril penetrates through the belt pulley and the mixing barrel to extend into the mixing shaft, two sides of the mixing shaft are provided with scraper blades by virtue of connecting rods, gaps are reserved between the scraper blades and the inner wall of the mixing barrel, the connecting rods and the scraper blades are of shell structures with inner cavities, the side walls of the scraper blades are provided with a plurality of through holes, the connecting rods are connected with the stirring shaft in a manner of sliding in the axial direction, the end parts of the connecting rods are provided with inclined openings and extend into the central through hole of the stirring shaft, the inclined openings are respectively positioned above the mandril, the outer side of the stirring shaft is fixedly connected with mounting sleeves, and the mounting sleeves are internally provided with springs fixedly connected with the outer walls of the connecting rods.

Description

technical field [0001] The invention relates to the technical field of chemical engineering, in particular to a chemical mixing tank. Background technique [0002] The traditional chemical mixing tank lacks a scraping device. After a period of use, thicker chemical raw materials will accumulate on the inner wall of the mixing tank, which will affect the mixing effect and efficiency. At present, there are chemical mixing tanks with scrapers. The scrapers are connected to the stirring shaft. When the stirring shaft rotates, the scrapers rotate to scrape off the chemical raw materials on the inner wall of the mixing tank. The advantage is to avoid the accumulation of raw materials. However, the disadvantages of the scraper with this structure are: the scraper is always in contact with the inner wall of the mixing tank, and its friction force is relatively large during stirring, which leads to higher heating of the inner wall of the mixing tank and lower stirring resistance.

[0002] The traditional chemical mixing tank lacks a scraping device. After a period of use, thick chemical raw materials will accumulate on the inner wall of the mixing tank, which will affect the mixing effect and efficiency.

At present, there are chemical mixing tanks with scrapers. The scrapers are connected to the stirring shaft. When the stirring shaft rotates, the scrapers rotate to scrape off the chemical raw materials on the inner wall of the mixing tank. The advantage is to avoid the accumulation of raw materials. However, the disadvantages of the scraper with this structure are: the scraper is always in contact with the inner wall of the mixing tank, and its friction force is relatively large during stirring, which leads to higher heating of the inner wall of the mixing tank and lower stirring resistance. Large, so the energy consumption of the mixer is too high
