Solid-liquid mixing and stirring device

Abstract

The invention discloses a solid-liquid mixing and stirring device. The solid-liquid mixing and stirring device comprises a shell body, wherein a rotary seat is arranged in the middle of the lower end in the shell body; the lower end of a stirring shaft is rotatably connected with the rotary seat; a limiting ring is rotatably connected with the middle of the stirring shaft; fixed rods are arranged at the outer side of the limiting ring; the other ends of the fixed rods are connected with an inner wall of the shell body; a plurality of stirring blades are uniformly connected with the stirring shaft; the outer ends of the stirring blades are connected with mounting bases; supports are arranged at the front sides of the mounting bases; the supports are rotatably connected with sleeve shafts; a plurality of small blades are arranged at the outer sides of the sleeve shafts; a feeding pipe is arranged at the upper end of the left side of the shell body; the feeding pipe comprises an outer pipe and an inner pipe; a cavity is formed between the outer pipe and the inner pipe; a plurality of cyclone inclined holes are uniformly formed in the inner pipe along the circumferential direction; the upper side of the outer pipe is connected with a water inlet pipe; a water pump is arranged on the water inlet pipe; the left end of the inner pipe is connected with a charging pipe and the charging pipe is provided with a charging pump. The solid-liquid mixing and stirring device is simple in structure, convenient to use, good in stirring effect, high in stirring efficiency and long in service life.

Description

technical field [0001] The invention relates to the technical field of stirring devices, in particular to a solid-liquid mixing and stirring device. Background technique [0002] Stirring device is a common device in chemical production. In the process of chemical production, it provides reaction space and reaction conditions for chemical reactions, and usually needs to fully stir the substances participating in the reaction to make the materials evenly mixed. The existing stirring device includes a shell and an agitator suspended in the shell. The upper end of the agitator protrudes from the shell and is connected with the motor output shaft fixed above the shell through the frame. The suspended agitator The stirring shaft is longer, during the stirring process, especially [0003] Especially when stirring quickly, the stirring shaft is prone to large torsional deformation, which will cause vibration and premature oil seal failure. And when solid-liquid mixing and stirrin...

[0003] Especially when stirring quickly, the stirring shaft is prone to large torsional deformation, which will cause vibration and premature oil seal failure

Moreover, when mixing and stirring solid-liquid, the liquid and materials are generally added separately. After such addition, the liquid and solid are layered, which is not conducive to mixing and affects the quality and efficiency of mixing.
