Problems solved by technology

[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 whe

Embodiment 1

[0037] Such as figure 1 As shown, a horizontal reinforced polysaccharide polymer modified stirring ball mill reactor, the main structure includes a stirring device 1, a ball mill cylinder 2, a grinding ball 3 placed in the ball mill cylinder 2, a feed inlet 4, a motor 5 and an outlet The feed port 26, the stirring device 1 includes the main shaft 21 connected in sequence, the guide key 24 for transmitting torque, the spline seat 14, the U-shaped frame 8 and the plow blade 7, and the electric motor 5 is connected to the stirring device 1 through the transmission device. The main shaft 21 is connected to and drives the U-shaped frame 8 to swing radially along the main shaft 21. The plow blade 7 is driven by the U-shaped frame 8 to stir the grinding ball 3 to roll in the ball mill cylinder 2. Directly above the reactor, the discharge port 4 is located on the side of the ball mill reactor and arranged at 90 degrees to the feed port 26 .

[0038] In this embodiment, a mixing test ...

Embodiment 2

[0040] The difference from Embodiment 1 lies in that arc plates 16 are provided at both ends of the inner cylinder of the ball mill cylinder.

[0041]In this embodiment, the viscous material was subjected to a mixing test, and the reaction reagent was added during stirring. After 2 hours, no material stuck to the inner wall of the ball mill cylinder and the arc plate.

Embodiment 3

[0043] The difference from Embodiment 1 is that the spline seat 14 is provided with a pin shaft hole at both ends of the diagonal line, and is hinged with the U-shaped frame 8 through the pin shaft 12 and the elastic retaining ring 13, and the described main shaft 21 is provided with 4 keyways, and described guide key 24 sections are fixed in the keyway with screw 25, and described spline seat 14 can be disassembled symmetrically, is fixed together with connecting plate 9 and bolt 10, nut 11, and all The main shaft 21 is provided with a positioning sleeve 17 that can be disassembled symmetrically, and the positioning sleeve 17 is set on the main shaft 21 through a screw 18 .

[0044] In this embodiment, a group of agitating plow blades is added to the main shaft 21. First, the screws 18 on all the positioning sleeves 17 on the original main shaft 21 are removed, the position of the spline seat 14 is adjusted, and a plow blade is added at the required position. The key seat 14 ...

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...
