Embodiment Construction
[0020] The present invention will be further described in conjunction with the accompanying drawings of the above-mentioned embodiments.
[0021] like figure 1 , figure 2 As shown, the sintered block extrusion molding machine described in the present invention includes an upper-level mixing system and a lower-level material-moving extrusion molding system. , its superior stirring system is a single-shaft stirring system, and the lower-level feeding system is a double-shaft feeding system. On the basis of the lower-level main shaft 8, there are two feeding shafts 15, and the feeding shaft 15 is provided with a feeding block 14 ,in:
[0022] The superior stirring system includes a stirring and kneading section and a spiral pre-pressing section 4 connected in sequence. The stirring teeth in the stirring and kneading section are arc-shaped kneading teeth 6, and the spiral auger 5 in the spiral pre-pressing section 4 is a gradual spiral agitator. Long, the diameter of the screw...

The present invention relates to an extrusion molding machine of sintered building blocks, which is used to mold and sinter building blocks. The present invention comprises a previous-stage mixing system and a later-stage kick-off extrusion molding system, wherein, the previous-stage mixing system is provided with a feed inlet, and the later-stage kick-off extrusion molding system is provided with an extruding head. The present invention is characterized in that the previous-stage mixing system is a single-shaft mixing system, the later-stage kick-off extrusion molding system is a double-shaft kick-off system, wherein, the previous-stage mixing system comprises a malaxating section and a spiral prepressing section which are orderly connected together, the mixing teeth in the malaxating section are arc-shaped malaxating teeth, the spiral packing auger in the spiral prepressing section is a gradient packing auger, the diameter and thread pitch of the screw of the feeding end are large, the diameter and thread pitch of the screw of the discharging end are small, an axial partitioning cutter is arranged at the position of the terminal discharging orifice of the spiral prepressing section, and a radial mincing cutter is arranged outside the axial partitioning cutter. The present invention can mold a large sintered building block product.
Description
technical field [0001] The invention relates to a sintered block extrusion molding machine, which is used for forming sintered blocks. Background technique [0002] With the development of my country's building materials energy-saving work, the building energy-saving index has been enforced to 65%. In my country's Eleventh Five-Year Plan, the green building materials science and technology support project has listed large-scale sintered block extrusion molding equipment as a national key development project. [0003] The original building block products are non-burning products, and cementitious materials are added to the raw materials, which are formed by pressing molding equipment. The molding of architectural standard bricks and hollow bricks is all extrusion molding. The extrusion molding machine includes an upper-level mixing system and a lower-level extrusion molding system. The molding raw materials are added from the inlet of the upper-level mixing system. Push it ...
