Abstract
The invention discloses a baffle-type continuous mixing mill which comprises a barrel, a front support frame, a rear support seat, a screw and a transmission shaft, wherein the barrel is fixed on the front support frame and the rear support seat; the screw is arranged in the barrel; and the transmission shaft is fixedly connected with the screw. The baffle-type continuous mixing mill is characterized in that the screw and the barrel are divided into a feeding part, a mixing part and an extrusion part respectively, a feeding hole is formed in the barrel in a position at the feeding part, and grooves in different shapes are formed in the screw and the barrel. The baffle-type continuous mixing mill has the advantages of continuity in feeding, high production efficiency, strong self-cleaning capability of the screw in the barrel and convenience in cleaning of the barrel and the screw during exchange of sizing material, so that the mixing mill is suitable for mixing of various sizing materials.
Description
Technical field
The present invention relates to a kind of mixing roll, specifically, relate to a kind of baffle-type continuous mixer, belong to the rubber compounding process equipment.
Background technology
In the existing baffle-type continuous mixer mixing process because screw rod is shorter, and shear between screw rod and sizing material, friction produces a large amount of heat energy, causes the temperature of barrel and screw rod to raise, the sizing material of can degrading when serious affects the melting effect of sizing material.Therefore, need a kind of new technical scheme to solve above-mentioned technical problem
Summary of the invention
The purpose of this invention is to provide a kind of baffle-type continuous mixer, the melting effect of this mixing roll is good, and the sizing material quality uniformity is high, and the temperature of sizing material is easy to control.
The technical solution used in the present invention is:
A kind of baffle-type continuous mixer, comprise head, cylindrical shell, screw rod and support, described screw rod is arranged in the cylindrical shell, described cylindrical shell is arranged on the support, be provided with charge door on the described cylindrical shell, be provided with a plurality of spiral shell ribs on the described screw rod, be provided with lining between described cylindrical shell and screw rod, be provided with several transverse baffles and longitudinal baffle in the helicla flute of described screw rod.
The height of described transverse baffle and longitudinal baffle all is lower than the height of spiral shell rib.
Described each transverse baffle is all perpendicular to two adjacent spiral shell faceted pebbles.
Be provided with many water channels between described cylindrical shell and lining.
The bottom of described support is provided with lowering or hoisting gear.
Advantage of the present invention is: in mixing process, longitudinal baffle can make sizing material produce shunting and mix, and transverse baffle then produces larger shear action to sizing material.So just can play the kneading similar with banbury, mix the effect with being uniformly dispersed, thereby guarantee the uniformity of sizing material quality.Simultaneously barrel is taked the effective cooling measure, the temperature of sizing material is easy to control, and operates more stable.
Description of drawings
Fig. 1 is overall structure schematic diagram of the present invention.
Fig. 2 is the partial enlarged drawing of screw rod of the present invention.
Wherein: 1, head, 2, cylindrical shell, 3, screw rod, 4, support, 5, charge door, 6, the spiral shell rib, 7, lining, 8, transverse baffle, 9, longitudinal baffle, 10, water channel, 11, lowering or hoisting gear, 12, helicla flute.
The specific embodiment
As depicted in figs. 1 and 2, a kind of baffle-type continuous mixer, comprise head 1, cylindrical shell 2, screw rod 3 and support 4, screw rod 3 is arranged in the cylindrical shell 2, cylindrical shell 2 is arranged on the support 4, for the ease of regulating height, be provided with lowering or hoisting gear 11 in the bottom of support 4, be provided with charge door 5 at cylindrical shell 2, be provided with a plurality of spiral shell ribs 6 at screw rod 3, be provided with lining 7 at cylindrical shell 2 and 3 of screw rods, and be provided with many water channels 10 at cylindrical shell 2 and 7 of linings, come barrel is carried out effective cooling to pass into cooling water, reduce the temperature of sizing material, in order to improve mixing effect, in the helicla flute 12 of screw rod 3, be provided with several transverse baffles 8 and longitudinal baffle 9, the height of transverse baffle 8 and longitudinal baffle 9 all is lower than the height of spiral shell rib 6, and each transverse baffle 8 is all perpendicular to two adjacent spiral shell faceted pebbles.
In mixing process, sizing material stopped and flow resistance strengthens when the transverse baffle of flowing through perpendicular to two adjacent spiral shell faceted pebbles, and shear action strengthens; Longitudinal baffle can be shunted sizing material; The tie point of longitudinal baffle and transverse baffle is split point.Under the effect of sizing material in screw rod rotation, flow forward along helicla flute, the part sizing material in the helicla flute then flow into the adjacent rear helicla flute from the longitudinal baffle top, intersects with sizing material in this helicla flute and mixes.Meanwhile, when another part sizing material is flowed through the transverse baffle top, just be subject to shear action.Like this, sizing material under the effect of longitudinal baffle and transverse baffle, is continuously carrying out cutting apart, mix, shearing and stirring repeatedly in mixing process, thereby reached sizing material is carried out mixing requirement.
