Description
Technical field
The invention belongs to building material machinery manufacturing technology field, particularly novel sintered thermal-insulating building block forming equipment.
Background technology
According to interrelated data demonstration in the recent period, at present the power consumption total amount in China every year is near 3,000,000,000 tons (signature coals), and building uses energy consumption to account for 30% of social total energy consumption, wherein heats and freeze to account for the 50-80% that building is used energy consumption, therefore, building energy conservation is significant.
The main body of building is a body of wall, and the main material of masonry panel (also being that long-term use proves best) is a fired brick, and still, common fired brick is to be difficult to reach the current standard-required of realizing building energy conservation 50% in all parts of the country.Therefore, sintered porous thin-walled heat insulating building block has been subjected to people's generally attention.
Sintered porous thin-walled insulation blocks, density is little, in light weight, thermal conductivity factor is low, heat transfer coefficient is little, save resource and manufacturing and the transportation energy, being the sintering walling new varieties that Europe is greatly developed over nearly 30 years, is the field technology revolution on the fired brick development history, has brought into play huge effect in European building energy conservation.
Sintering heat insulation building block is to realize energy-conservation material base and the technical support of homogenous material heat-preserving wall, is to realize the practicable important measures of building energy conservation, is the desirable approach that realizes energy-saving and emission-reduction, is the developing direction of China's fired brick.China heavy clay industry association proposes the suggestion of development sintering heat insulation building block in 2009 annual work programs: be badly in need of at present producing sintered heat insulating heat insulation building block raw material processing performance research and estimating, the exploitation of equipment, is united tackling key problem, is promoted the production and the application of novel sintered heat insulating building block at organizational strength.
A workman wants to do his work well, must first sharpen his tools, the key problem in technology of the heat insulation building block of sintered heat insulating is that the key in production equipment, the production equipment is an extruder, and the key of extruder is a mould, the heat insulation building block of sintered heat insulating hole is many, wall thin, the piece type is big, and to realize the instructions for use of building energy conservation 50% and 65%, its heat transfer coefficient must be at 0.71-0.37/ (w/m
2K), thermal conductivity factor is at 0.33-0.24/ (w/mk), compression strength 〉=15/mpa, thus very high to the specification requirement of extrusion molding mould, up to the present, still find no design in China and make the mould that is specifically designed to sintered porous thin-walled heat insulating building block.
Traditional hollow brick mould is to make a slip of the tongue from the machine of solid brick to cross basically, both suit one simple and easy core frame formed in the rectangle machine mouth of solid brick, can not effectively regulate the direction of extruding pug and the equilibrium that keep-ups pressure, can not solve specification requirements such as the sintering heat insulation building block wall is thin, the hole is many, the type body is big again, therefore, it is impossible using traditional hollow brick extrusion die to produce sintering heat insulation building block
Summary of the invention
The objective of the invention is weak point, design a kind of mould for extruding and forming sintering heat preservation building block for producing with the development sintering heat insulation building block at the above-mentioned background technology, and the interface differential technique of realization and domestic existing extruder, and then promote building energy conservation.
Specifically, mould for extruding and forming sintering heat preservation building block, it is made up of head, machine mouth and core frame three parts, head is the taper tubular, big end is circular port, and small end is a rectangular opening, and the drum surface of head four direction is up and down installed 4 groups of accent mud plates, the small end of head connects with the machine mouth, and the core frame is installed in the machine mouth and is connected by the end face of core frame fixation clip with machine mouth flange; The machine mouth is made up of machine mouth flange, machine mouth dividing plate, machine actinal surface plate, accent clod and press strip, and it is one with bolting with one heart successively that each part internal orifice keeps; The core frame comprises support knife rest, flanged plate and knife rest, core bar and core print, and two ends while core bar and knife rest that core print is fixed on core bar connect and compose the core frame component, and the core frame component is fixed on the flanged plate.
Main feature of the present invention: 1, at first in the design of the four direction up and down of head the mud of accent plate is arranged, realized comprehensive adjusting to extruding pug, can effectively control pug and flow to and flow, balanced extrusion pressure makes that mudflow is harmonious pushes ahead.2, have 32 to transfer clods in the design of the four sides of machine mouth, each piece can both independent regulation, thereby has guaranteed to extrude the wall thickness unanimity of building block.3, a whole set of relatively mould of core frame is an individual components, can need to change fast by producing in the use.
