Problems solved by technology

However, the gap between the stator and the rotor cannot be zero, so after it reaches a certain precision, it is impossible to further refine it.
At present, it can only achieve a crushing capacity of about 1 micron, and it is difficult to achieve nano-processing

Embodiment Construction

[0012] A further description of the roller-type ultrafine grinding pump of the present invention will be given below in conjunction with the description of the drawings and embodiments.

[0013]Referring to Fig. 1, Fig. 2 and Fig. 3, a plurality of rotors 13 are sleeved on the drive shaft 9 equipped with long flat keys 8. The two ends of drive shaft 9 are contained in the axle holes of front and rear pump covers 24,38 through bearing 18. Two lip-type sealing rings 119 of the upper sleeve of the shaft 9 are respectively contained in the shaft holes of the front and rear pump covers for the grease of the sealing lubricating bearing 18, preventing it from entering the pump chamber. Front and rear glands 28,39 are loaded on the front and rear pump covers 24,38 with screws 27, and press the bearing 18 to stop it from moving out of the pump cover. The lip type sealing ring II30 of adorning in the front gland 28 inner cavity can stop the outstretching end of grease along the shaft 9...

Abstract

The invention relates to a roller type ultramicro grinding pump, which is the main working mainframe used in an ultramicro grinder for the ultramicro refined processing for colloidal materials and can be applied for ultra-fine crushing and grinding of fluids with solid particles in the technical fields of food, chemical industry, and pharmacy. The roller type ultramicro grinding pump comprises a plurality of stator shells, a plurality of rotors, a plurality of rollers, a port plate, a plurality of pump covers and a drive shaft, which is characterized in that: a plurality of rotors with rollers on the circumference are sleeved on the drive shaft, each rotor is positioned in a stator shell with the eccentric magnitude size of e; a port plate is arranged between the two sets of rotors and stator shells; the sets of stator shells, the sets of rotors, the port plate, the front pump cover and rear pump cover are connected and assembled in series to form the roller type ultramicro grinding pump; and a plurality of cooling water channels communicated with each other are arranged on the pump covers, the stator shells and the port plate used for water-cooling the temperature rise when the pump is grinding.

Description

Technical field [0001] The roller type ultra-fine grinding pump is a main working host used in the ultra-fine grinding machine for ultra-fine processing of colloidal materials. It can be used in food, chemical, pharmaceutical and other fields for ultra-fine crushing and grinding of fluids containing solid particles. Background technique [0002] At present, there are many kinds of grinding and crushing equipment for ultrafine crushing of solid particles, such as ball mills, rubber mills, jet mills, homogenizers and high shear machines. Among them, ball mill, rubber mill and high shear machine are a kind of mechanical kinetic energy to apply shear force, friction force and mechanical vibration force to the crushed solid particles to achieve material crushing and refinement. The ball mill is mainly used for dry powder crushing. The rubber mill and high shear machine are ground and broken by wet colloid. Due to the limitation of their movement mode and structural principle, ...
