Description
Technical field
The utility model relates to the building material production facility technical field, is a kind of multi-functional two-way pressurization and vibration brick making machine specifically.
Background technology
The manufacturing machine that is used to produce adobe for building at present is a lot, as: multiple brickmaking mechanicals such as octal dish mechanical type brickmaking machine, mechanical type brickmaking machine, oscillatory type block machine, spiral extruded type brickmaking machine.
More than these machineries can be used for producing adobe for building, have superiority but use respectively.Octal dish mechanical type brickmaking machine is present service time of long a kind of mechanical type brick equipment.It adopts the raw material in the mechanical type bent axle supercharging mode compacting raw material material chamber, and the compression moulding time has only 1-2 second, and the adobe exhaust is bad.The green strength that compacting is come out is not high, rough surface, and steam-cured back anti-folding freeze-thaw resistance brick is not up to standard, the brick output mode adopts manpower, adobe to fall corner angle easily.The brick profile is plain, and every equipment per tour will account for 2-3 people, human cost is higher, this in addition equipment can only be suppressed standard brick, produces that the hollow brick technology is immature, fault rate is high, and can produce the requirement that hollow brick and building block save material with domestic miscellaneous equipment has certain gap, this besides equipment yield is not high, separate unit generally per hour produces below the 1200-1800 piece standard brick, but this equipment also possesses some good points, and its low price, small investment, consumable accessory are relatively cheap, easy to maintenance.Present this equipment is used more at small-sized brick field, certain areas also have certain market at home, reduce trend gradually but have.
Mechanical stamping formula brickmaking machine is copied the structure of mechanical press, also adopts mechanical type bent axle supercharging mode pressing unfired brick, with the difference of octal dish mechanical type brickmaking machine be exactly pressuring method be from top to bottom, and octal dish mechanical type is from lower to upper.Its output, molding cycle adobe performance and octal dish mechanical type brickmaking machine difference are little.Present this equipment is used few.
The oscillatory type block machine is these several years a kind of brick equipments of application development gradually, can be used for producing various adobes, comprises standard brick, hollow brick, building block etc.Its adopts the mode production adobe of raw material vibration moulding, so the pressure of green brick forming is not high, packing is less, and it is high to be difficult to sign indicating number.For sign indicating number must be at every mould supporting plate of pad below the adobe that come out to certain altitude, correspondingly increased investment.The adobe that this device fabrication is come out is generally in order to natural curing, and the natural curing cycle is longer, generally all about 28 days, and could form certain initial strength remove supporting plate after 1-2 days, so the supporting plate large usage quantity uses the place also bigger.The also many employing hydraulic cylinder demouldings of present this equipment and reinforced.Advanced modes such as the automatic control of PLC, its automaticity is higher, and the maximum at present shortcoming of this equipment is that just base intensity is not high, needs a large amount of supporting plates.
Mainly with the machinery of the higher raw material brickmaking of plasticity index such as clay or gangue, the adobe of its production is mainly with sinter molding for spiral extruded type brickmaking machine.The shortcoming of this equipment clearly, at first its energy consumption is high especially, is example with energy-saving 50 machines, during its extrusion pressure 2MPA, installed power just reaches about 150KW, when its extrusion pressure is 4MPA, installed power is more up to more than the 250KW.Non-energy-saving installed power is higher; Next is that the scope of application of this equipment shaping raw material has certain restriction, and it must be the raw material that certain viscosity is arranged.Clay raw material country absolute prohibition uses.
By above analysis as can be seen, building trade lacks a kind of cost performance height, the big adobe of output intensity height just at present, and without the high novel brick equipment of supporting plate automaticity.
