Description

A kind of mixer

Technical field:

The utility model relates to a kind of mixer.

Background technology:

The existing agitator that in aerated food (as cake, candy, cream, chocolate etc.), inflation latex industrial products production processes such as (as artificial leather, foam coatings), gas, little granular solids (as powder) and liquid material is stirred, even require under the situation of steady temperature, continuously gas and material are fully mixed, reach multiple two kinds or above gas, granule situation solid are evenly spread in the liquid material; And general agitator is not reach above-mentioned requirement, existing agitator or can not stir continuously, or can stir continuously, but stirring and mixing effect does not reach requirement.

Summary of the invention:

Goal of the invention of the present utility model is to provide a kind of and can mixes continuously, simultaneously, and the mixer that stirring and mixing effect is very desirable.

The utility model is to realize like this, comprise the shell that has material import and export, stirring shaft, its special feature is that wall evenly is laid with several rows of vertical in the enclosure, the tooth of laterally equal marshalling, the width of the tooth of every row tooth is identical, on the stirring shaft with outer casing inner wall on the toothrow place of staggering also be provided with toothrow, toothrow on outer casing inner wall and the outer casing inner wall is whole produced together, stirring shaft and the toothrow that is arranged on the stirring shaft also are whole produced together, toothrow link to each other with shell on same position on a circular protrusion is arranged, be provided with axis hole near that side of material inlet on the shell, the power transmission shaft of stirring shaft is arranged in the axis hole by bearing, the power transmission shaft that mixes the stirring shaft in the axis hole between the storehouse in bearing and shell is provided with a pair or more of mechanical seal (can according to the different different sealings of instructions for use change), and the axis hole sidewall between the every pair of mechanical seal is provided with water-guiding hole.During work, the material that need stir enters from material inlet and mixes in the chamber, and the toothrow relativity of the toothrow of wall and stirring shaft is filled down and mixes in the enclosure, and the material that mixes is discharged from the outlet on the shell of toothrow another side.Because material enters into outlet from import and discharges, and must pass through toothrow, toothrow produces relative crawl space and produces repeatedly brute force and draw and approach and shearing reaches abundant stirring and mixing effect passing various materials rotating; The power transmission shaft that mixes the stirring shaft in the axis hole between the storehouse in bearing and the shell is provided with a pair or more of mechanical seal, therefore, both can fully mix material continuously, simultaneously, can prevent that again material from entering foreign matter on bearing and the bearing and entering and mix in the chamber.

In order to prevent that material is from directly flowing between the toothrow of the toothrow of outer casing inner wall and gap between rotating shaft and rotating shaft outer wall or material directly flows between the toothrow of the toothrow of rotating shaft outer wall and gap between shell and outer casing inner wall, cause these materials can not be subjected to the abundant stirring of toothrow, between the toothrow of outer casing inner wall, be provided with boss between the toothrow of rotating shaft outer wall.During work, material is subjected to stopping of boss and the sphere of action that enters toothrow, and material can be stirred fully.

Here, shell is provided with the interlayer that can feed the insulation media, and interlayer is provided with the insulation media and imports and exports.Employing can feed the interlayer of insulation media, can accurately control the technological temperature that mixes effectively, with the quality that guarantees to mix.

In being provided with the stirring shaft of toothrow, be provided with the interlayer that can feed the insulation media, the power transmission shaft of stirring shaft is a hollow axle, be provided with the pipe of straight-through stirring shaft interlayer in the hole of axle, the part that the power transmission shaft of stirring shaft is positioned at stirring shaft is provided with the hole that is connected with interlayer.Like this, pipe will be incubated media and import in the interlayer, and the insulation media in the interlayer goes out by the orifice flow of hole, power transmission shaft, thereby form the circulation of insulation media.

Here, draw in interlayer in order successfully to be incubated media, the position between a pair of mechanical seal of power transmission shaft is provided with the perforation of through transmission axis hole, and axis hole is provided with the outlet of insulation media accordingly.Like this, the insulation media comes out the back by axis hole insulation media outlet discharge from the transmission axis hole, and simultaneously, insulation media (generally being water) is lubricated mechanical seal.

Compared with the prior art the utility model has and can mix continuously, simultaneously, and the advantage that stirring and mixing effect is very desirable.
