Description

The wet method pulverizer mill

Technical field

The utility model relates to a kind of wet method super-fine crushing grinding device that is referred to as the wet method pulverizer mill, and this wet method pulverizer mill can be according to the online instant adjusting material grinding fineness of grind of arts demand in the equipment operation process.

Background technology

The production of a lot of products and processing need be carried out wet method and pulverizes and grind in the modern industry, and require control material grinding fineness of grind to be distributed in certain scope, the too thick and meticulous quality that all can influence product.As: the pigment of fine chemistry industry industry, dyestuff, paint, printing ink, plastic additive etc.; The injection of biological medicine industry, antibiotic, health products, cell tissue fragmentation etc.; The pesticide of pesticide industry, the agent of kind clothing, herbicide etc.; The jam of food service industry, chocolate mass, food additives or the like.Wet method super-fine pulverizing at present can make the material smashing fineness reach micron-sized common equipment sand mill and colloid mill.Because sand mill uses abrasive medias such as bead, zirconium oxide bead, abrasive media easily pollutes material, so sand mill is not suitable for industries such as medicine, food, cosmetics.Though colloid mill does not use abrasive media,, also can pollute material because it mostly is the open type operation greatly; And the production capacity of colloid mill is little, efficient is not high, incompatible big industrial production.And these two kinds of equipment are subjected to a lot of restrictions for big, the mobile not good material of viscosity; And material pulverizing fineness of grind is wayward.Therefore, press for a kind of ultra-fine wet method disintegrating apparatus that can be applied to above-mentioned industry.

Summary of the invention

The purpose of this utility model is easily to cause deficiencies such as material pollutes, production capacity is little, efficient is not high, be not suitable for the not good material of viscosity large fluidity, material pulverizing fineness of grind is wayward in order to solve existing ultra-fine wet method disintegrating apparatus, a kind of wet method super-fine crushing grinding device that is referred to as the wet method pulverizer mill is provided, this wet method pulverizer mill is not used abrasive media and is adopted the closed operation, so can not pollute material; Adopt the supercharging blade wheel structure to force feeding, production capacity is big, be applicable to the material that the viscosity large fluidity is not good; Especially the online adjustment structure of this wet method pulverizer mill uniqueness can be changeed by regulating when the equipment operation according to arts demand, the gap length between stator regulates the pulverizing fineness of grind of product immediately, thereby raise the efficiency, guarantee product quality.

The utility model solves the problems of the technologies described above the technical scheme that is adopted: the critical component of this wet method pulverizer mill is rotor that tapering is arranged and the stator that pair of matched is closed, on rotor and the stator roll flute is arranged, position to axial by regulating rotor and stator is to regulate the gap between rotor, stator, be subjected to high speed shear and grinding repeatedly because the rotation of the high speed of rotor makes in the narrow space of material between rotor and stator roll flute, thereby reach pulverizing, homogeneous and emulsification.The rotation regulating part is housed on the housing, and according to the technological requirement of material, the gap passing through under the non-stop-machine situation between rotation regulating part adjusting rotor, stator makes the material grinding fineness of grind reach the requirement of process stipulation, and is easy and simple to handle, reliable.Through pulverizing the material that ground, discharge end at rotor and stator is subjected to the effect of the supercharging impeller of rotation at a high speed, order about material and accelerate to pass through by force the speed of narrow space between rotor, stator roll flute, the supercharging impeller of rotation has improved the discharging lift of material simultaneously at a high speed, thereby is applicable to the material that the viscosity large fluidity is not good.The material of the utility model rotor and stator is stainless steel or steel alloy, and through heat treatment increasing case hardness and mechanical strength, thereby the service life of improving equipment.

The utility model is to realize like this, wet method pulverizer mill structure described in the utility model comprises support, settle motor and bearing block on the support, bearing block connects housing, main shaft by bearings is housed on the bearing block, main shaft is connected by shaft coupling with motor, shaft coupling is equipped with safety guard outward, motor rotates at a high speed by the shaft coupling drive shaft, rotor and supercharging impeller are housed on the main shaft, near bearing block one end mechanically-sealing apparatus is housed at main shaft, this mechanically-sealing apparatus has the envelope pressure energy power of 0～1.0Mpa, can effectively prevent the material from leakage in the equipment, and play the effect of secluding air simultaneously, the housing of equipment is installed on the bearing block, and stator and rotation regulating part are housed on the housing, and discharging opening is housed on the housing, the import cover plate is housed on the stator, the import cover plate is equipped with charging aperture, thereby the rotation regulating part that is installed on the housing can be regulated stator shaft orientation displacement adjusting rotor, gap between stator reaches the requirement of process stipulation with control material grinding fineness of grind.

Rotor of the present utility model and stator are conical structure, and its tapering is 15～65 °.

On rotor of the present utility model and the stator roll flute is arranged, the height of this roll flute is 0.5～6mm.

On the rotation regulating part of the present utility model handle is housed.

The beneficial effects of the utility model are, this wet method pulverizer mill can not pollute material, and production capacity is big, be applicable to the material that the viscosity large fluidity is not good, can be when equipment operation, according to the online instant adjusting material grinding fineness of grind of arts demand.Easy and simple to handle, reliable.
