Horizontal reinforced polysaccharide polymer modification agitating ball mill reactor

Abstract

The invention discloses a horizontal reinforced polysaccharide polymer modification agitating ball mill reactor, and aims to provide a ball mill which is uniform in material agitating, free of dead angle in ball milling, controllable in temperature in ball milling, and convenient to maintain. The horizontal reinforced polysaccharide polymer modification agitating ball mill reactor is mainly structured by comprising an agitating device, a grinding barrel, a constant temperature system and a machine frame, wherein the agitating device and the grinding barrel are horizontally arranged on the machine frame; the agitating device is driven by a motor; a U-shaped frame capable of being swung in a radial direction is arranged on the agitating device; a replaceable plough disc is arranged on the U-shaped frame; the grinding barrel is provided with a double-layer structure which is served as a cooling water sleeve; a coolant inlet and a coolant outlet are arranged on the grinding barrel; a feeding port is arranged in 90 degrees respect to a discharging port; positioning plates are arranged at two ends of the grinding barrel; and when discharging, the discharging port is rotated at 90 degrees to downwards discharge. The horizontal reinforced polysaccharide polymer modification agitating ball mill reactor is a reactor applicable to polysaccharide polymer modification.

Description

technical field [0001] The invention relates to a powder processing equipment, especially a ball mill, which can be used for powder ball milling, and can also be used for solid-solid phase reaction or liquid-solid phase reaction, such as a reactor for strengthening the modification of polysaccharide polymers . Background technique [0002] The reaction process of chemical reaction between solid and solid to form new solid substance is called solid phase reaction. Because the solid phase reaction has the advantages of no solvent, high selectivity, high yield, simple process, no environmental pollution, solvent saving, energy consumption reduction and no deflagration, it is an ideal synthetic method and has become a development trend. A new approach to green chemistry and technology and an important means of developing green materials and products. At present, it has been widely used in organic synthesis reaction, coordination chemical reaction, polymer modification, prepara...

[0007] 1. Chinese Patent Publication No. CN200820081427.9, published on May 6, 2009, the application discloses a plow-type stirring device for a high-energy ball mill, including a spline mounting plate, a plow, a swing rod, a pin, Composed of screws, it overcomes the problem that in the traditional ball mill, after the stirring rod is worn out, the distance between the top of the rod and the ball mill cylinder becomes larger, which makes the mixing of the material and the grinding ball insufficient and the ball milling efficiency drops.

Its disadvantage is that the spline mounting plate is integral, and there is still the problem of inconvenient when increasing or decreasing the number of plow blades

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.
