Abstract

The utility model relates to an efficient colloid mill. The efficient colloid mill is composed of an enclosure, a motor, a main shaft, a fixed mill, a rotary mill, a pump, a feeding pipe, a discharging pipe and a reflowing pipe, wherein the discharging pipe and the reflowing pipe of the colloid mill are respectively mounted on the enclosure at the lower part of the rotary mill; a filtering net is mounted between the discharging pipe and the enclosure of the rotary mill; the enclosure is provided with a window which corresponds to the filtering net in size; materials are crushed through the fixed mill and the rotary mill; the crushed fine materials enter the discharging pipe through the filtering net so as to prevent the fine materials from being repeatedly crushed; and the rough materials attached to the filtering net are washed by the materials rotating at a high speed and then enter the reflowing pipe to be crushed again, so that the aim of efficient and superfine crushing of the materials is realized. The efficient colloid mill disclosed by the utility model is simple to operate and low in cost.

Description

A kind of efficient colloid mill

Technical field

The utility model relates to a kind of crushing technology, particularly a kind of efficient colloid mill.

Background technology

In the prior art, colloid mill is to be gone round and round a millstone by motor drives to make relative High Rotation Speed with the mill of deciding that matches, material to be machined produces downward spiral impulsive force by itself weight or pump, be subject to the physical actions such as powerful shearing force, frictional force, dither when seeing through the gap between deciding, going round and round a millstone, make material by effectively emulsification, dispersion and pulverizing, reach the effect of material fining pulverizing and emulsification.When ultra-fine grinding, still need to grind several times problem, be to adopt return duct repeatedly to grind to solve at present, but return duct repeatedly to grind be that efficient is not high with all materials mill together all.

Summary of the invention

The purpose of this utility model will overcome defects exactly, and a kind of new efficient colloid mill is provided.

The technical solution of the utility model is: a kind of efficient colloid mill, by casing, motor, main shaft, fixed mill, go round and round a millstone, pump, feed pipe, discharge nozzle and return duct form, the discharge nozzle of colloid mill and return duct are installed in respectively on the casing of the bottom of going round and round a millstone, between discharge nozzle and the casing of going round and round a millstone, screen pack is installed, the window corresponding with the screen pack size arranged on the casing, the material of High Rotation Speed in the casing can be washed screen pack by window, the length of the window on the casing of deciding mill of colloid mill and the length of screen pack surpass colloid mill go round and round a millstone the position casing girth 1/4, more preferably greater than 1/2.Material enters from feed pipe, by decide mill and go round and round a millstone between the gap, surely grind with going round and round a millstone and do the powerful shearing force that relative High Rotation Speed forms, frictional force, the physical actions such as dither, make the material that passes through by effectively emulsification, disperse and pulverizing, material after the pulverizing enter decide mill and go round and round a millstone the below working chamber in, material is done centrifugal rotation at a high speed under the effect of pump, thin material enters discharge nozzle by screen pack, avoided thin material to be repeated to pulverize, be attached to thick material on the screen pack by the material of High Rotation Speed flushing and enter return duct and again pulverized, thereby reach the purpose of material high-efficiency ultra-fine grinding.

Advantage of the present utility model and effect are: the utility model has replaced colloid mill in the past, has solved the not high problem of colloid mill efficient.The utility model has solved the not high problem of colloid mill efficient with simple form, the cost when having reduced colloid mill work.The utility model is simple to operate, and cost is low.

Description of drawings

Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.

The structural representation of Fig. 1 efficient colloid mill of the present utility model

The structural representation of the vertical section of Fig. 2 efficient colloid mill of the present utility model

The specific embodiment

Describe the utility model in detail below in conjunction with embodiment:

As Fig. 1,2 described be a kind of structure of efficient colloid mill,

Such as Fig. 1,2 described be a kind of structure of efficient colloid mill, a kind of efficient colloid mill, by motor 1, casing 2, main shaft 3, surely grind 4, go round and round a millstone 5, pump 6, feed pipe 7, discharge nozzle 8 and return duct 9 form, the discharge nozzle 8 of colloid mill and return duct 9 are installed in respectively on the casing 2 of 5 bottoms of going round and round a millstone, between discharge nozzle 8 and 5 the casing 2 of going round and round a millstone, screen pack 10 is installed, the window 11 corresponding with screen pack 10 sizes arranged on the casing 2, the material of casing 2 interior High Rotation Speeds can be washed by 11 pairs of screen packs 10 of window, the length of the window 11 on the casing of deciding mill 42 of colloid mill and the length of screen pack 10 surpass colloid mill go round and round a millstone 5 positions casing 2 girth 1/4.Material enters from feed pipe 7, by deciding mill 4 and the gap between 5 of going round and round a millstone, surely grind 4 and 5 do the powerful shearing force that relative High Rotation Speed forms with going round and round a millstone, frictional force, the physical actions such as dither, make the material that passes through by effectively emulsification, disperse and pulverizing, material after the pulverizing enters in the working chamber of deciding mill 4 and 5 belows of going round and round a millstone, material is done centrifugal rotation at a high speed under the effect of pump 6, thin material enters discharge nozzle 8 by screen pack 10, avoided thin material to be repeated to pulverize, be attached to thick material on the screen pack 10 by the material of High Rotation Speed flushing and enter return duct 9 and again pulverized, thereby reach the purpose of material high-efficiency ultra-fine grinding.

Claims

1. efficient colloid mill, by casing, motor, main shaft, surely grind, go round and round a millstone, feed pipe, discharge nozzle and return duct form, the discharge nozzle and the return duct that it is characterized in that colloid mill are installed in respectively on the casing of the bottom of going round and round a millstone, between discharge nozzle and the casing of going round and round a millstone, screen pack is installed, the window corresponding with the screen pack size arranged on the casing, the material of High Rotation Speed in the casing can be washed screen pack.

2. efficient colloid mill according to claim 1, the length that it is characterized in that the screen pack installed on the casing of colloid mill surpass colloid mill go round and round a millstone the position casing girth 1/4.
