Problems solved by technology

It solves the problem of solid distribution difference caused by solid material accumulation and solid material settlement on the paddle disc and baffle, but its solid and liquid feeding method does not solve the phenomenon of "powder block" or "powder cluster" and dust, due to the liquid The feed is not evenly distributed into the solids, increasing the dispersion time of the solids in the liquid, resulting in prolonged mixing times

Embodiment

[0022] As shown in Figures 1, 2 and 3, the horizontal solid-liquid mixing device of the present invention mainly includes a mixing chamber 10 surrounded by a cylinder 15, on which a solid feed port 5, a liquid feed pipe 6, a Material port 17, exhaust port 13, cleaning port 12, cylinder body 15 center has stirring shaft 8. The rotating shaft 7 is sealed by the stuffing box 4 . The shaft of the horizontal solid-liquid mixing device is composed of a rotating shaft 7, a stirring shaft 8 and a stirring paddle 9, which can be easily disassembled. The liquid feed pipe 6 is provided with 4 to 20 holes of 0.5 to 5 mm. In this embodiment, 6 small holes with a diameter of 4 mm are uniformly distributed. Change the number and position of the holes to prevent the powder from flying when the powder material is added. The stirring paddle 9 is fixed on the stirring shaft 8, the distance between the outer edge of the stirring paddle 8 and the inner wall of the cylinder body 15 is 5.5mm, and ...

Abstract

The horizontal solid-liquid mixer includes a speed reducer, bearing seats, mixing chambers of a barrel with powder inlet and liquid inlet in the upstream and discharge port and gas outlet in the downstream, a stirring shaft in the center of the barrel and with ends connected through the rotating shaft to the bearing seats, stirring vane wheel fixed onto the stirring shaft, baffles on the wall of the barrel to separate the barrel into several chambers in the changeable size, and stirring oars fixed onto the stirring vane wheel. Compared with available technology, the present invention has the advantages of high mixing efficiency, high mixing speed, high mixed material homogeneity, and wide application range.

Description

technical field [0001] The invention relates to a solid-liquid mixing device, in particular to a horizontal solid-liquid mixing device. Background technique [0002] At present, solid-liquid mixing basically adopts adding solid-liquid two-phase materials into a vertical stirring reactor in a certain proportion, and mixing is realized by a stirring device. However, the mixing effect is not ideal for materials that require high mixing uniformity, fine particle size, and two-phase insoluble materials. The main performance is that the solid particles are easy to deposit and agglomerate, the powder is easy to grow, and the mixing time is long. In the case of high density, several stages of mixing are often required to achieve the effect, resulting in high process cost. [0003] Chinese patent application 200410084721.1 discloses a vertical solid-liquid mixing device and a mixing method. In this patent application, the mixing chamber is divided into several smaller mixing areas ...
