The broken mud device of vacuum-extruder
Technical field
The utility model relates to a kind of broken mud device, is specifically related to a kind of broken mud device that is applied to vacuum-extruder, belongs to brick and tile production equipment technical field.
Background technology
Double-stage vacuum extruding machine is in current brick-tile industry, to use the most general brick equipment, is mainly made up of higher level's unit and subordinate's unit.Wherein in higher level's unit, then pug first stirs through the fragmentation of mud smash machine structure, and the pug after fragmentation enters vacuum chamber and vacuumizes, to reach the needed packing of base substrate.The vacuum of pug is the key factor that affects product quality, and the degree of fragmentation of pug and vacuum are closely bound up.The existing mud smash machine structure mud breakers that are arranged on agitator tank discharging opening place that adopt, when pug is discharged through discharging opening, by rotation mud breaker, cut into slices raw material more.But in actual production, mud breaker sheet is due to the consideration of manufacture and factors of limit life, can not make very thin blade, due to the viscosity factor of raw material, in use do not reach the result of blade in theory, section is all often bulk or bulk simultaneously at all, the air being wrapped in raw material can not get discharging, do not reach the needed vacuum of moulding, thus when moulding due to the effect of air, make product easy to crack.In addition, mud breaker and stirring blade etc. is arranged in same rotating shaft, and the discharging speed of pug and mud breaker rotary speed are limited in certain scope, the raising of restriction production efficiency.
Utility model content
According to above the deficiencies in the prior art, technical problem to be solved in the utility model is: provide a kind of vacuum-extruder broken mud device, pug degree of fragmentation is high, and the vacuum after vacuumizing is high, makes base substrate packing good, and product quality and yield rate are high.
The broken mud device of vacuum-extruder described in the utility model, comprises agitator tank, and stirring propulsion assembly is set in agitator tank, and agitator tank discharging opening place mounted sieve, arranges some sieve apertures on sieve plate.
Pug fully stirs and is advanced into discharging opening under the effect of stirring propulsion assembly, and under discharging opening sieve plate stops, pug is extruded by sieve aperture, and the pug of extruding and sieve aperture shape adapt.Because screen size is less, pug degree of fragmentation improves greatly, and the vacuum after vacuumizing is high, and product packing is good.
Described sieve aperture cross section is polygon, circle or strip, preferably strip.
Described sieve aperture longitudinal section is rectangle or trapezoidal, and wherein the long limit of trapezoid cross section is feed end, and minor face is discharge end.
Described sieve plate is split type, comprises upper sieve plate, lower sieve plate, and split type sieve plate maintenance is convenient.
Described sieve plate is integral type, is easy to manufacture and install.
Described stirring propulsion assembly comprises rotating shaft and is arranged on successively stirring blade, the screw reamer in rotating shaft, stirring blade and rotating shaft composition mixing part, screw reamer and rotating shaft composition promotion part, rotating shaft rotarily drives stirring blade pug is stirred, screw reamer is pushed ahead pug, the power that provides pug to extrude.
The course of work:
Raw material and water are in charging aperture enters agitator tank, by stirring blade, pug is stirred, screw reamer promotes pug and advances to the discharging opening of agitator tank, under discharging opening sieve plate stops, pug is extruded by sieve aperture, the pug of extruding enters in the vacuum chamber of blanking box, enters subsequent processing after vacuumizing.
Because the size of sieve aperture is less, the pug degree of fragmentation of extruding is high, and the air content in it is low, high through vacuumizing final vacuum degree, makes base substrate packing good.
Compared with prior art, the beneficial effect that the utility model has is:
The broken mud device of this vacuum-extruder makes pug degree of fragmentation high by sieve plate is set, and the vacuum after vacuumizing is high, makes base substrate packing good, and product quality and yield rate are high; Removed mud breaker, the extruded velocity of pug can flexible modulation, has improved production efficiency.

Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model embodiment is described further.
Embodiment 1
As shown in Figures 1 to 3, the broken mud device of this vacuum-extruder, comprise agitator tank 4, blanking box 1, blanking box 1 is arranged on agitator tank discharge port end, the interior vacuum chamber that arranges of blanking box 1, agitator tank 4 rear portions arrange charging aperture 7, the interior stirring propulsion assembly that arranges of agitator tank 4, stirring propulsion assembly comprises rotating shaft 6 and is arranged on successively stirring blade 5, the screw reamer 3 in rotating shaft 6, stirring blade 5 forms mixing part with rotating shaft 6, screw reamer 3 forms promotion part with rotating shaft 6, rotating shaft 6 connecting drive devices 8, and drive unit 8 comprises drive motors, reductor etc.Agitator tank 4 discharging opening place mounted sieves 2, are uniformly distributed some sieve apertures 9 on sieve plate 2, sieve aperture 9 cross sections are polygon, circle or strip, preferably strip, and strip is made up of the rectangle at middle part and the arc at two ends.Sieve aperture 9 longitudinal sections are rectangle or trapezoidal, and wherein the long limit of trapezoid cross section is feed end, and minor face is discharge end, and trapezoid cross section is easy to extruding of pug, and square-section is easy to processing and manufacturing.Sieve plate 2 is split type, comprises upper sieve plate, lower sieve plate, and upper sieve plate, lower sieve plate are bolted on agitator tank 4.
Embodiment 2
The present embodiment sieve plate 2 is integral type, is easy to processing and installs, and all the other are with embodiment 1.
The course of work:
Raw material and water are in charging aperture 7 enters agitator tank 4, drive unit 8 drive shafts 6 are rotated, drive stirring blade 5 to stir pug, screw reamer 3 promotes pug and advances to the discharging opening of agitator tank 4, under discharging opening sieve plate 2 stops, pug is extruded by sieve aperture 9, and the pug of extruding enters in the vacuum chamber of blanking box 1, enters subsequent processing after vacuumizing.
