Mud is pushed to an extrusion runner by means of a spiral reamer; a mud cutting, extruding and stirring device is used for cutting the mud into multiple linearly-extruded mud strips; the multiple linearly-extruded mud strips are extruded again to form an integral mud strip in an extruding and stirring region, departing from a feeding direction, of the mud cutting, extruding and stirring device; the integral mud strip sequentially passes through a machine head, as well as a core apparatus and a machine opening which are connected with the machine head, to form mud strips, provided with uniformly distributed holes, to be cut. By the adoption of the scheme provided by the invention, the mud is sufficiently mixed by the extrusion runner, so that the mud can be molded more densely; the mud cutting, extruding and stirring device positioned inside the extrusion runner can be used for ensuring that the mud can be mixed more uniformly, the layering phenomenon of the mud extruded by the spiral reamer is reduced, and the quality of manufactured bricks is improved.

Description

Vacuum extruder pug extrusion method
Technical field
The present invention relates to brick-making technology field, particularly relate to a kind of vacuum extruder pug extrusion method.
Background technology
Owing to not shrinking after sintering heat-reserving brick sintering, the common quality defect of appearance is fewer than other wallings a lot, therefore obtains in building trade and applies more and more widely.Along with sintering heat-reserving brick application and generally use, the application of vacuum extruder also constantly expands, and relevant device develops rapidly, and the requirement of critical component mould progressively improves.It is little that the mould generally used at present also exists extrusion pressure, the problems such as pug mixing is uneven, this seriously governs sintered perforated brick towards the tiny and future development staggered of pass, vacuum extruder domestic at present can't produce the tiny and sintering heat-reserving brick staggered of pass, this be due to this pass sintering heat-reserving brick to former and technological requirement very high.It requires that vacuum extruder has larger extrusion pressure, and pug can be made fully to mix.If pressure is too little, the wet base intensity extruded is just low, yielding time dry.This is needed to the extruding runner designing a kind of vacuum extruder, make its this device can increase extruding to pug, pug is mixed, meets the forming requirements of high-quality sintering heat-reserving brick.
When vacuum extruder carries out work, pug enters head place through screw reamer in machine barrel, at head and machine notch portion extruded formation mud bar.It is inadequate that pug ubiquity when shaping briquetting pressure, and pug mixing is uneven, thus causes adobe cohesive force to decline, insufficient strength, and the defect such as easily deform during brick bat drying.In addition, pug, when extruding, is subject to resistance and the friction of head inwall, pug temperature is raised, causes pug moisture loss, and mud bar corner easily produces cracking phenomena.Therefore, a kind of novel lubricating and cooling of design is needed to solve this problem.
In addition, because the pug in vacuum extruder machine barrel is that the mode rotated by screw reamer is pushed ahead, so pug still rotates after entering head, thus cause pug to produce lamination, in some cases, the layering that extrusion molding is formed can cause adobe internal structure existing defects, and adobe qualification rate is declined.Therefore, a kind of novel extruding agitating device must be designed to reduce pug lamination.
