Double-side-tooth double-grinding-cavity colloid grinder

Abstract

A double-side-tooth double-grinding-cavity colloid grinder comprises a grinding disc device, a seal device, a gap adjusting device, a heat exchange circulation device, a power device and other parts which are arranged in a colloid grinder grinding body. The grinding disc device comprises a rotor 6 and two stators 7. The rotor 6 is fixedly connected to a spindle 1 and is arranged in the center in the grinding body 4. The stators 7 are arranged at the two ends in the grinding body 4 correspondingly. The two end faces of the rotor 6 are each provided with grinding teeth. Only one end face of eachstator 7 is provided with grinding teeth. The grinding teeth of the two end faces of the rotor 6 mesh with the grinding teeth of the end faces of the two stators 7 correspondingly. According to the seal device, the spindle 1 axially penetrates through the geometric centers of the stators 7, the rotor 6 and grinding cavity end covers 8, and the seal device is arranged between the spindle 1 and thegrinding cavity end covers 8. According to the gap adjusting device, the stators 7 and grinding cavities of the grinding body 4 are connected through oriented flat keys 16, adjusting screws 12 penetrate through screw seats 14 on the grinding cavity end covers 8 to be fixedly connected with the stators 7 through threads, the adjusting screws 12 are fixedly connected to the screw seats 14 through two reverse nuts 10 and 11, and guide discs 15 are connected to the ends of the adjusting screws 12. The heat exchange circulation device comprises an interlayer structure of the grinding body 4, the outer wall of the grinding body 4 is connected with a heat conduction oil inlet and outlet 5, and circulation heat conduction oil is introduced into the interlayer. The double-side-tooth double-grinding-cavity colloid grinder is novel in design, compact in structure, convenient to use and efficient and reliable and has wide practicability and obvious economic value.

Description

technical field [0001] The invention relates to asphalt processing equipment, in particular to a colloid mill with double-sided teeth and double grinding chambers, belonging to the technical field of asphalt processing equipment. Background technique [0002] At present, the working principle of the domestic colloid mill is that the rotor is driven by a high-speed motor to rotate at a high speed relative to the stator. The shear force, friction force, high-frequency vibration, high-speed vortex and high-speed grinding and other physical effects promote the rapid and effective crushing, dispersion, homogenization and emulsification of colloidal materials, and realize the ultra-fine crushing and emulsification of colloidal materials. However, in most existing colloid mills, the gap between the stator and the rotor is fixed, which cannot be well adapted to shearing colloidal materials with different particle sizes, or producing different asphalt products, such as modified aspha...

AI Technical Summary

Problems solved by technology

However, in most existing colloid mills, the gap between the stator and the rotor is fixed, which cannot be well adapted to shearing colloidal materials with different particle sizes, or producing different asphalt products, such as modified asphalt, rubber asphalt or emulsified asphalt, etc. ; There is also a colloid mill with more advanced technology, which adjusts the gap between the stator and the rotor through the translation of the main shaft, but the sealing of the main shaft is not ideal and is easy to leak; third, the stator and the rotor in the current colloid mill are single-ended With grinding teeth, there is only one grinding chamber, the effective grinding area is limited, and the production efficiency is not high
