Background technology
General commonly used mixedly pinch, kneading and extrusion equipment have continuously and batch two kinds of forms with regard to operating type, has strong shearing to mix with regard to its basic principle and pinch, strong convection mixes to be pinched etc., varied especially with regard to version.Traditional mixedly pinch, kneading, extrusion equipment have edge runner, single screw extrusion machine, double screw extruder, continuous mixer etc., these equipment have exists mixed-precision higher but power consumption is big, yields poorly, can't realize big output operation, there are defectives such as the higher but mixed-precision of output is low in the equipment that has.
Along with industrial expansion, especially now the development of recycling economy, as utilize various mine tailings to prepare the novel wall material industry, resemble ardealite especially, red mud, flyash and carbide slag etc. are produced the industry of materials for wall, not only require to mix and pinch equipment and can realize big output operation, the power consumption index request is low, and to realize high-precision mixed pinching, not only reach macroscopical mixed-precision, and reach the microcosmic mixed-precision, the basis for estimation of its mixed-precision is not to judge by traditional measuring means but judge that by the intensity of end article a kind of in a word high mixing pinched precision, big output, the equipment of low-power consumption is the necessary equipment of present novel wall material industry.
The utility model content
The purpose of this utility model is to propose a kind of mixing continuously to pinch extruder, when making big output operation the power consumption index lower, mediate the precision height, realizes highly difficult, high accuracy microcosmic kneading.
The utility model is finished the technical scheme that its practical novel task takes:
A kind of mixing continuously pinched extruder, comprises positive feed device, main drive gear, cylindrical shell frame; The positive feed device is arranged on the top of cylindrical shell frame charging aperture, and the cross section that is positioned at the inner chamber of cylindrical shell frame upper shell is horizontal " 8 " font or circle; Be provided with to mix and pinch rotor and described mixing pinched rotor and be at least one, mixing and pinching rotor subject is a main shaft, main shaft is provided with forces feeding screw and described pressure feeding screw to be at least two groups, be positioned at the pitch of the pressure feeding screw pitch of feed end, force the pitch of feeding screw to be successively decreased successively for many groups that are arranged on the main shaft by feed end to discharge end greater than the pressure feeding screw that is adjacent; Force between the feeding screw fixed cover to be set in many groups, fixed cover is provided with the instrument of pinching that mixes; By going out stub bar and mix a group of pinching rotor and force feeding screw to form pressing mechanism, described with go out stub bar and form mixed a group of pinching rotor of pressing mechanism and force feeding screw to be positioned at close discharge end position; The described output section that goes out stub bar is laterally " 8 " font or circle, the discharge opening that the output section that goes out stub bar has interval that material is passed through to be provided with.
The described many groups of rotation direction unanimities of forcing feeding screw of pinching on the rotor main shaft of mixing.
Mix and to pinch rotor and be set to two, two to mix the pressure feeding screw rotation directions of pinching on the rotor main shaft opposite.
Describedly go out the stub bar output section and have the width of cloth bar that is provided with at interval, constitute the discharge opening that material is passed through between the width of cloth bar.
Describedly go out the stub bar kink and pinch on the rotor main shaft and be fixed by bolts on the frame mixing.
Describedly mix that to pinch instrument be a stripe board structure, the top is provided with rake teeth, and the rake teeth bottom is provided with blade, has reinforcement between blade and the rake teeth, and rake teeth is opposite in the axial direction with blade.
The utility model adopts the beneficial effect of technique scheme to be:
1, novelty simple in structure mainly contains positive feed device, cylindrical shell frame, mixes composition such as the parts of pinching rotor, transmission device, cylindrical shell, and the cylindrical shell frame is a demountable structure, safeguards simple and convenient.
2, go out the stub bar combination and be combined on the cylindrical shell frame, go out stub bar and mix one group of pressure feeding screw composition pressing mechanism pinching rotor, going out stub bar is the part of cylindrical shell frame, also detachable the replacing conveniently of while.
3, the geometry of cylinder lumen is horizontal " 8 " font or circle, can guarantee that material does not have the dead angle in cylindrical shell, and all materials all can obtain identical kneading machine meeting.
4, mix and to pinch rotor and force feeding screws by many groups and mix to pinch instrument and form, many groups are forced the pitch difference of feeding screw, the geometric angle that mixes the instrument of pinching also changes, the pressure feeding screw pitch of feed end is bigger, the closer to discharge end, force the helical pitch of feeding screw more little, it also is the closer to discharge end that its geometric angle that mixes the instrument of pinching changes, mix that to pinch instrument more little to the conveying capacity of material, the final purpose of all these variations is the brute force shearings that realize strengthening to material, reinforcement is forced feeding screw and is mixed the suitable gap of the instrument of pinching and cylinder inboard wall maintenance the kneading function of material, realizes the cleaning to cylinder inboard wall.
5, mix the design of pinching rotor and not only can effectively increase production capacity, and when treating the bigger material of viscosity, mix with two and to pinch rotor and not only can increase output and can also realize mixing the mutual cleaning of pinching between the rotor, prevent that material is bonded on the axle, and then equipment is mixed pinch disabler.
6, mix the structure uniqueness of pinching instrument, same mix to pinch to have on the instrument make opposite rake teeth of material movement direction and blade, thereby realize that material moves to a direction because the axial flow that it produces material is different, adjacent two blend tools make material realize rubbing the promptly mixed function of pinching, simultaneously because mix the instrument of pinching to the conveying capacity of material less than the conveying capacity of forcing feeding screw, between the two also to material have powerful rub promptly to mix pinch function, reached higher level by the multistage mixed mixed degree of pinching of pinching between the final material.
7, force the feeding feeding screw near one group of the discharge end position and go out stub bar to constitute the final brute force extruding of material between the two, this group is forced the pitch minimum of feeding screw, soaks into by the powerful disperse that this mechanism further reaches between the material through the powerful material of pinching that mixes.Material is formed the material cake discharging of abundant kneading by the slit that goes out stub bar by pressing mechanism in this link.
8, mix the instrument of pinching, force feeding screw all to pass through Wear-resistant Treatment, a kind of is to adopt the high-wear-resistant alloy material, a kind of be on its contactant charge level weldering to be coated with hard wear-resisting.
