Description
The application is application number 201510052337.1, on 01 30th, 2015 applying date, title " vacuum extruder pug
Extrusion method " divisional application.
Technical field
The present invention relates to brick-making technology field, particularly relate to a kind of vacuum extruder pug extrusion side with extruding runner
Method.
Background technology
Not shrinking after sintering due to sintering heat-reserving brick, the common quality defect of appearance is fewer than other wallings a lot, is therefore building
Build industry to have obtained increasingly being widely applied.Along with the application of sintering heat-reserving brick with commonly use, vacuum extruder
Application the most constantly expands, and relevant device develops rapidly, and the requirement of critical component mould steps up.Generally make at present
The mould problems such as to there is extrusion pressure little, and pug mixing is uneven, this seriously govern sintered perforated brick towards
Pass direction that is tiny and that stagger is developed, and the most domestic vacuum extruder can't produce the sintering that pass is tiny and staggers
Insulating brick, this is owing to the sintering heat-reserving brick of this pass is the highest to former and technological requirement.It requires vacuum brick extruding
Facility have bigger extrusion pressure, it is possible to make pug be sufficiently mixed uniformly.If pressure is the least, the wet base intensity of extrusion is the lowest,
Be dried time yielding.This needs to design the extruding runner of a kind of vacuum extruder so that it is this device can increase pug
Extruding, makes pug mix homogeneously, meets the forming requirements of high-quality sintering heat-reserving brick.
When vacuum extruder is operated, pug advances at head through screw reamer in machine barrel, at head and
Machine oral area divides extruded formation mud bar.It is inadequate that pug generally also exists briquetting pressure when molding, and pug mixing is uneven, from
And cause adobe cohesive force to decline, and insufficient strength, it is susceptible to the defects such as deformation during brick bat drying.Additionally, pug is when extrusion,
By resistance and the friction of head inwall, make pug temperature raise, cause pug moisture loss, mud bar corner easily to produce cracking
Phenomenon.Accordingly, it would be desirable to design a kind of novel lubricating and cooling to solve this problem.
Push ahead further, since the pug in vacuum extruder machine barrel is the mode rotated by screw reamer, so
Pug still rotates after entering head, thus causes pug to produce lamination, and in some cases, extrusion molding is formed
Layering can result in adobe internal structure existing defects, makes adobe qualification rate decline.Therefore, it is necessary to design a kind of novel extruding
Agitating device reduces pug lamination.
Summary of the invention
Brief overview about the present invention given below, in order to the basic reason about certain aspects of the invention is provided

For a kind of vacuum extruder pug extrusion method with extruding runner, implement vacuum extruder such as Fig. 1 institute that the method uses
Show, including head 25, machine barrel 24, connect in machine barrel 24 and have rotating screw reamer 21, fixing between machine barrel 24 and head 25
Connect and have extruding runner 23, the cavity that extruding runner 23 is through before and after having, the aperture of cavity is gradually reduced to two ends from middle part,
The pug segmentation extruding agitating device 22 for pug being carried out cutting it is fixedly connected with in extruding runner 23；
Described method includes:
Pug is pushed to extrude runner by spiral reamer, and described pug is cut into a plurality of by pug segmentation extruding agitating device
The mud bar of straight line extrusion；
The described mud bar of a plurality of straight line extrusion, deviates from the extruding stirring area in supplied materials direction at pug segmentation extruding agitating device
Again one overall mud bar of formation it is extruded；
Overall mud bar is sequentially via head, and the core being connected with head has and machine mouth, is formed with the hole that is evenly distributed
Mud bar to be slit.
Owing to the aperture of cavity is gradually reduced to two ends from middle part, namely define can accommodating more of a middle part protrusion
The die cavity of many pugs.Pug collects in this die cavity, and stops the rotation via the effect of pug segmentation extruding agitating device, and quilt
Segmentation is stirred.Pug is being extruded through head after collecting again so that the brick of formation is fine and close, intensity is high.
The such scheme that the present invention provides, extruding runner 23 can make pug be sufficiently mixed, and mud material forming is finer and close, position
