Description
Technical field
The present invention relates to a kind of vacuum-extruder tool, the powder material that will have certain humidity specifically is squeezed into the two-stage vacuum extruder of regulation cross dimensions.
Background technology
At present; Existing vacuum-extruder is the main higher level's mixer that constitutes by seal box with the sealing screw blade that is contained in the seal box generally; Is that subordinate's main frame and vacuum system, speed reduction gearing and the dynamical system etc. that the master constitutes are formed by material receiving box with the screw reamer of extruding that is contained in the material receiving box, and higher level's mixer is accomplished stirring, extruding, cutting and combined vacuum system and the manufacturing process of subordinate's extrusion mechanism completion strip adobe.Because conventional equipment is perfect inadequately on sealing part, cause through the stirred materials piece and contain a large amount of residual airs, after this thing piece packing after the extrusion molding is poor, and intensity does not reach requirement, thereby causes the product percent defective that makes higher; Secondly, because the vacuum parameter in the seal box does not control to the best, make that product quality and the effect after the moulding is relatively poor.
Summary of the invention
The objective of the invention is deficiency, improve a kind of two-stage vacuum extruder for solving the problems of the technologies described above, its good sealing effect, the thing piece packing after the production is good, and intensity improves greatly.
The present invention is the deficiency that solves the problems of the technologies described above; The technical scheme that is adopted is: a kind of two-stage vacuum extruder; Comprise by the shaft in agitator tank and the agitator tank being the main rabbling mechanism that constitutes, being main extrusion mechanism, speed reduction gearing and dynamical system that be provided with charging aperture at an end of agitator tank, blanking box is arranged on charging aperture one end of agitator tank by material receiving box and the screw reamer that is contained in the material receiving box; On blanking box, also be provided with the vavuum pump that is used for the regulating box internal pressure; Be used to guarantee that vacuum is-0.09Mpa in the blanking box, the corresponding discharging opening that is provided with the band tapering on the side blanking tank wall corresponding with charging aperture, shaft passes the discharging opening of charging aperture and blanking box successively and is arranged on the opposite side casing of blanking box through bearing; Circumference at discharging opening is provided with comb stream plate; The annular component that described comb stream plate is made up of a plurality of fan-shaped notched plates, annular component is arranged on round discharging opening on the inwall of blanking box, and the crown of comb stream plate and the down suction between the corresponding shaft are 35-60 millimeters; On the shaft at discharging opening place, be provided with cutting knife, the discharge port of blanking box bottom and the feeding mouth sealed butt joint of extrusion mechanism.
Described shaft is provided with dismountable helical blade.
Described shaft is provided with the protective layer with axle surface parcel.
Vacuum in the described blanking box≤-0.09Mpa.
Described rabbling mechanism is made up of motor I, decelerator I and agitator tank, and the power output shaft of motor I is connected with the interior shaft of agitator tank through the decelerator I.
Described extrusion mechanism is made up of motor II, decelerator II and material receiving box, in material receiving box, is provided with the screw reamer with material extruding output.
The described screw reamer top that in material receiving box, is positioned at also is provided with switch-plate, and switch-plate is driven by the motor II.
Because conventional vacuum-extruder sealing effectiveness is poor, the vacuum in the material receiving box does not reach requirement, makes that the interior material compacting degree of material receiving box is relatively poor; The fragment of brick of producing contains more bubble and space, so intensity is lower, because Equipment Design is perfect not to the utmost; Still do not reach vacuum requirements in the case even improve the power of vavuum pump, secondly, in material receiving box, also have the vacuum requirement an of the best; If vacuum is lower, the fragment of brick after the moulding makes intensity not reach requirement owing to containing more bubble, if vacuum is higher; Not only waste electric energy, and difficulty comparatively when causing the screw reamer convey materials owing to material receiving box internal pressure reason, production efficiency is low; Through evidence, guarantee vacuum in the blanking box≤-during 0.09Mpa, preferred vacuum is-0.09Mpa; This moment, discharging speed was fast, and the material compacting degree is good, and product strength promotes greatly.
The invention has the beneficial effects as follows:
1, the present invention is simple in structure; Through the discharging opening place in blanking box comb stream plate is set, except oneself's sealing of material, and the gap adjustment measure that combines to comb the stream plate; Make the sealing part sealing effectiveness of entire equipment improve greatly; Vacuum in the assurance blanking box≤-0.09Mpa, the material compacting degree improves, and the intensity of product also is improved simultaneously.
2, the present invention is provided with blanking box through the side at agitator tank, will pass through stirred materials comb stream plate shunting material through dentation at first when getting into blanking box, and the material of whole ring-type is dispersed into little stick; Thereby be convenient to the remaining bubble in the thing piece is removed; Secondly, comb stream plate is set also has the function of regulating the discharging opening size, make sealing effectiveness better; Vacuumize more easily, improved the packing of material.
3, cutting knife also is housed on the shaft of corresponding discharging opening in blanking box; And cutting knife is over against the setting of comb stream plate, and its effect is that the bar piece after handling through comb stream plate is cut into sheet, maximized reduction residual air once more; Gas clean-up, the packing of increase material.
4, in extrusion mechanism, be provided with switch-plate and friction backing plate, through switch-plate raw material set aside, reduce the wastage, the friction that strengthens shaft and raw material through the friction backing plate again reduces and stops up, and raises the efficiency.
