Horizontal type stirring ball-milling reactor for intensifying bentonite modification

Abstract

The invention discloses a horizontal type stirring ball-milling reactor for intensifying bentonite modification, and provides a ball mill which is uniform in material blending, has no stirring dead angle and controllable ball-milling temperature, can add materials at any time, and is high in ball-milling efficiency and used for intensifying bentonite modification. According to the invention, the main body structurally comprises a bracket, a stirring shaft mounted on the bracket, a stirring device mounted on the stirring shaft and composed of plough disc stirring blades and S-shaped stirring blades, and a ball-milling cylinder; the S-shaped stirring blades are mounted on the adjacent two groups of plough disc stirring blades; the stirring shaft is connected with a motor through a belt; the ball-milling cylinder comprises two layers of an outer cylinder and an inner cylinder; a cooling liquid flow leading channel is formed between the outer cylinder and the inner cylinder; the outer cylinder is provided with a coolant inlet pipe, a feed opening, a discharge opening and a coolant return pipe; the coolant inlet pipe and the coolant return pipe are respectively connected with a coolant inlet pipeline and a coolant return pipeline of a cooling system; milling balls are arranged in the ball-milling cylinder. The reactor can be used for polysaccharide superpolymer modification.

Description

technical field [0001] The invention relates to a powder processing equipment, in particular to a ball mill, which can be used for powder ball milling, solid-solid phase reaction or liquid-solid phase reaction, such as a reactor for strengthening bentonite modification. Background technique [0002] Bentonite is abundant in the world and widely distributed. At present, the proven reserves are nearly 10 billion tons. According to statistics, calcium-based bentonite accounts for 70%-80% of the world's geological reserves, while high-quality sodium-based bentonite resources are very limited. my country's bentonite reserves are second only to the United States, ranking second in the world. In the distribution of montmorillonite resources in the world, calcium-based montmorillonite accounts for about 70%-80%. The content of natural sodium-based bentonite is very small, with reserves of less than 500 million Ton. 90% of my country's montmorillonite is calcium-based montmorillonit...

AI Technical Summary

Problems solved by technology

Its shortcoming is that there are no arc plates at both ends of the cylinder, and there are dead angles; there is a gap between the stirring rod and the inner cylinder wall, such as ball milling with viscous materials, some materials cannot be fully stirred; after the cylinder rotates, Some locations are inconvenient to feed at any time

Its disadvantages are: the bottom of the ball mill cylinder is 0-30 degrees along the axis, the material is accumulated at the bottom, and there is a gap between the stirring rod and the inner cylinder wall, which is not conducive to the full mixing of the material.
