Abstract
The utility model relates to a super-fine pulverizer, which comprises a machine frame, a feeder, a pulverizing machine casing, a main shaft arranged in the pulverizing machine casing, a rotating disk, fan, a fixed cutter and a movable cutter. The utility model is characterized in that the pulverizing machine casing is a gradually expanding volute casing type machine casing; the fixed knife is composed of a fixed inner tooth disk and a fixed outer tooth disk, and the movable cutter is composed of a movable inner tooth disk and a movable outer tooth disk. The utility model has the advantages that the disintegrating fineness of materials is high, particularly plastic or rubber particles, and one-time disintegrating fineness of materials can reach more than 120 meshes.
Description
One, technical field
The utility model relates to a kind of pulverizer, especially a kind of ultrafine crusher.
Two, technical background
The pulverizer that existing food, pharmacy, feed and other industry are used is generally by frame, feeder, pulverizing casing be loaded on main shaft, rotating disk, fan, stationary knife and the moving knife etc. pulverized in the casing and form.The general maximum of fineness that this pulverizer is pulverized when comminuting matter especially plastic grain or rubber grain can only reach 80 orders, and the pulverizing chamber temperature rise, the meltable soft junction piece of material, make pulverizer the energy consumption height, yield poorly, cause material grinding efficient low.
Three, technology contents
At above-mentioned shortcoming, the purpose of this utility model is to provide the ultrafine crusher that a kind of smashing fineness is thin, crush efficiency is high.
The purpose of this utility model is to realize like this, a kind of ultrafine crusher, comprise frame, feeder, pulverizing casing and be loaded on main shaft, rotating disk, fan, stationary knife and the moving knife of pulverizing in the casing, it is characterized by the pulverizing casing is that the flaring scroll casing type is pulverized casing, stationary knife is by fluted disc in fixed and decide outer tooth disk and form, and moving knife is formed by moving interior fluted disc and moving outer tooth disk.The rough segmentation that fluted disc and moving interior fluted disc are mainly used in material in fixed is loose and dispersed material, and its groove is a stepped tooth; Deciding outer tooth disk and moving outer tooth disk, to be mainly used in the fine powder of material broken, and its groove is saw shape tooth.
Be the disposable pulverizing fineness of raising material and the efficient of pulverizer, the feeder of pulverizer is made up of screw feeding device and the material cooling device that is located in the screw feeding device; The material cooling device mainly is made up of cooling fluid carrier pipe and cooling fluid playpipe.The material cooling device be make material enter pulverize casing and pulverize before by deep cooling but to have black brittleness and to reach the vitrifying state, with the disposable pulverizing fineness of raising material and the efficient of pulverizer.
For the cooling effect of material further is provided, be provided with the cooling fluid playpipe at the feed cavity place that pulverizes casing.
For improving the velocity of discharge of comminuting matter, pulverize on the casing at the flaring scroll casing type and be provided with the secondary air mouth.
The advantage that the utility model is compared with prior art had is:
1, the material grinding fineness is thin, especially plastics or rubber particles, the thinnest 300 orders that reach of its smashing fineness.
2, the crush efficiency height of pulverizer, the disposable pulverizing fineness of material can reach more than 120 orders, especially pulverizes after cooling at material.

Five, specific embodiment
As shown in Figure 1, Figure 2, Figure 3 and Figure 4, a kind of ultrafine crusher, comprise frame 1, feeder 11, pulverize casing 10 and be loaded on main shaft 3, rotating disk 5, fan 4, stationary knife and the moving knife of pulverizing in the casing, pulverize casing 10 and pulverize casing for the flaring scroll casing type, stationary knife is by fluted disc in fixed 7 and decide outer tooth disk 9 and form, and moving knife is formed by moving interior fluted disc 6 and moving outer tooth disk 8; Decide interior fluted disc 7 and decide outer tooth disk 9 to be fixed on the pulverizing casing 10, moving interior fluted disc 6 and moving outer tooth disk 8 are fixed on the rotating disk 5, and rotating disk 5 is fixedly connected on the main shaft 3; The rough segmentation that fluted disc 7 and moving interior fluted disc 6 are mainly used in material in fixed is loose and dispersed material, and its groove is a stepped tooth 19; Deciding outer tooth disk 9 and moving outer tooth disk 8, to be mainly used in the fine powder of material broken, and its groove is saw shape tooth 18; On flaring scroll casing type pulverizing casing, be provided with secondary air mouth 20.The feeder of pulverizer is made up of screw feeding device 12 and the material cooling device that is located in the screw feeding device; The material cooling device mainly is made up of cooling fluid carrier pipe 13 and cooling fluid playpipe 14; Be provided with cooling fluid playpipe 14 at feed cavity 17 places that pulverize casing 10.
Operation principle: material enters in the screw feeding device 12, the cooling liquid nitrogen enters the cooling fluid carrier pipe 13 from feed liquor nitrogen mouth 16, by cooling fluid playpipe 14 liquid nitrogen is sprayed to material in the screw feeding device 12 again, make material enter pulverize casing 10 and pulverize before by deep cooling but having black brittleness and to reach the vitrifying state, the amount of liquid nitrogen that can regulate input by adjusting liquid nitrogen valve 15; Material after being cooled is admitted to be pulverized in the casing 10, and the centrifugal force that utilizes fluted disc to rotate generation at a high speed quickens material, makes material earlier by deciding interior fluted disc 7 and deciding the slot of outer tooth disk 9 by coarse crushing and dispersion; By move the slot of interior fluted disc 6 and moving outer tooth disk 8 finish shear pulverize again by moment for material; The dynamic pressure that utilizes the rotation of fan 4 and fluted disc to produce can be discharged powder rapidly; Utilize the interior buildup of air-flow cleaning casing of the secondary air mouth 20 on the casing, can observe the material grinding situation by the peep hole of pulverizing on the casing 10 2.
