Description
The application is application number 201510052338.6, on 01 30th, 2015 applying date, denomination of invention " vacuum extruder
Extruding runner " divisional application.
Technical field
The present invention relates to brickmaking mechanical technical field, more particularly, to a kind of extruding runner being fixed in vacuum extruder.
Background technology
Do not shrink due to after sintering heat-reserving brick sintering, 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.Application with sintering heat-reserving brick and commonly using, vacuum extruder
Application also constantly expands, and relevant device develops rapidly, and the requirement of critical component mould steps up.Generally make at present
It is little that mould has an extrusion pressure, the problems such as pug mixing is uneven, this seriously govern sintered perforated brick towards
Pass is tiny and direction that stagger is developed, and vacuum extruder domestic at present can't produce the sintering that pass is tiny and staggers
Insulating brick, this is because the sintering heat-reserving brick of this pass is very high to former and technological requirement.It requires vacuum brick extruding
Machine has larger extrusion pressure, and pug can be made to be sufficiently mixed uniformly.If pressure is too little, the wet base intensity of extrusion is just low,
Yielding when being dried.This is needed design a kind of extruding runner of vacuum extruder so as to this device can increase to 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, in head and
Machine oral area divides extrusion molding to form mud bar.Pug generally existing in molding briquetting pressure not, and pug mixing is uneven, from
And lead to adobe cohesive force to decline, and insufficient strength, it is susceptible to the defects such as deformation during brick bat drying.Additionally, pug is in extrusion,
By resistance and the friction of head inwall, so that pug temperature is raised, lead to pug moisture loss, mud bar corner easily produces cracking
Phenomenon.Accordingly, it would be desirable to design a kind of new lubricating and cooling to solve this problem.
Further, since the pug in vacuum extruder machine barrel is to be pushed ahead by the mode that screw reamer rotates, so
Pug still rotates after entering head, thus leading to pug to produce lamination, in some cases, extrusion molding is formed
Layering can result in adobe internal structure existing defects, so that adobe qualification rate is declined.Therefore, it is necessary to design a kind of new extruding
Agitating device is reducing pug lamination.
Content of the invention
Brief overview with regard to the present invention is given below, to provide the basic reason with regard to certain aspects of the invention
Solution.It should be appreciated that this general introduction is not the exhaustive general introduction with regard to the present invention.It is not intended to determine the key of the present invention
Or pith, nor is it intended to limit the scope of the present invention.Its purpose only provides some concepts in simplified form, with
This is as the preamble in greater detail discussed after a while.
It is an object of the invention to provide a kind of extruding runner being fixed in vacuum extruder, described extruding runner has
The cavity of insertion in front and back, the aperture of described cavity is gradually reduced from middle part to two ends, is fixedly connected useful in described extruding runner
Split extruding agitating device in the pug that pug is carried out with cutting.
The such scheme that the present invention provides, extruding runner can make pug be sufficiently mixed, and mud material forming is finer and close, is located at
Pug segmentation extruding agitating device within extruding runner, can make pug mixing more uniform, reduce pug by screw reamer
Lamination during extrusion, improves the quality of institute's brickmaking.
