Abstract
The invention relates to a double-screw high-concentration mixer. The double-screw high-concentration mixer comprises a machine frame, and a machine barrel, a hopper, two screws and conveying screw sleeves and a plurality of mixing discs which are arranged on the machine frame, wherein a chamber is arranged inside the machine barrel; the two screws are parallel to each other and are rotationally arranged inside the chamber; a feed port is formed at one end of the machine barrel; a discharge port is formed at the other end of the machine barrel; the conveying direction of the screws is from the feed port to the discharge port; the hopper is arranged on the machine barrel and is communicated with the feed port; the screws are sleeved by the conveying screw sleeves and the mixing discs sequentially in the conveying direction; a certain clearance is formed between the adjacent mixing discs; a plurality of pins are fixedly arranged at parts, corresponding to the clearances between the mixing discs, on the inner wall of the machine barrel; and chemical adding holes are formed in parts, corresponding to the conveying screw sleeves, at the upper part of the machine barrel. The double-screw high-concentration mixer adopts a double-screw structure, so that the mixing efficiency of the double-screw high-concentration mixer is at least twice of the original mixing efficiency; and the pins are arranged on the inner wall of the machine barrel, so that the mixing effect is further improved.
Description
Technical field
The present invention relates to the high dense blender of a kind of twin-screw.
Background technology
In paper-making pulping field, particularly machinery pulping and waste paper pulp-making field, satisfy arts demand such as slurry bleaching in order to improve size performance, slurry is fully mixed with chemicals, to improve reaction efficiency, reduce chemical cost, this is one extensively needs and important technical process.Under the same conditions, slurry reaction concentration has material impact to reaction efficiency, and concentration is higher, and reaction efficiency is higher, and chemical cost is lower, and therefore, high dense mixing and reaction process have represented the chemically treated trend of current pulping process.The high dense blender of slurry more and more comes into one's own as a kind of important pulping equipment.
At present, the high dense blender of slurry is the high dense blender of single shaft, because mixing efficiency is lower, has restricted the raising of slurry physical property.Become the chemical cost major reason that remains high.
Summary of the invention
The object of the invention is to solve the low problem of the high dense blender mixing efficiency of above-mentioned slurry, provides a kind of twin-screw high dense blender, is specifically realized by following technical scheme.
The high dense blender of a kind of twin-screw, the high dense blender of described twin-screw comprises frame and is arranged on machine barrel on the frame, hopper, two screw rods and conveyor screw cover and some mixing pans, described machine barrel inside is provided with chamber, described two screw rods are parallel to each other and be arranged on rotationally in the described chamber, described machine barrel one end is provided with charging aperture, the other end is provided with discharging opening, be that the conveying of screw rod is reverse from charging aperture to discharging opening direction, described hopper is arranged on the machine barrel and with charging aperture and is communicated with, described conveyor screw cover and some mixing pans are socketed on the screw rod along throughput direction successively, there is certain interval between the adjacent mixing pan, on the described machine tube inner wall with mixing pan between partial fixing corresponding to gap be provided with some pins, the machine barrel top part corresponding with the conveyor screw cover is provided with medicine feeding hole.
The high dense blender of described twin-screw, it further designs and is, and described mixing pan middle part is provided with the installing hole that adapts with the screw rod external diameter, and this mixing pan outer rim is evenly distributed with three combination tooths.
The high dense blender of described twin-screw, its further design be, the gap between the mixing pan on the combination tooth in the high dense blender of described twin-screw on the screw rod and another screw rod is relative.
The present invention has adopted double-screw structure, so that the mixture operation efficient of blender was doubled more at least; Owing to being provided with pin at machine tube inner wall, further having strengthened mixed effect.
Description of drawings
Fig. 1 is structural representation of the present invention.
Fig. 2 is the plan structure schematic diagram of the high dense blender of twin-screw shown in Fig. 1.
Fig. 3 is the mixing pan structural representation.
The specific embodiment
Below in conjunction with Figure of description and specific embodiment the present invention is further specified.
The high dense blender of this twin-screw comprises frame 1 and is arranged on machine barrel 2 on the frame, hopper 3, two screw rods 4 and 5 and 16 mixing pans 6 of conveyor screw cover, machine barrel 2 inside are provided with chamber, two screw rods are parallel to each other and be arranged on rotationally in this chamber, machine barrel 2 one ends are provided with charging aperture 21, the other end is provided with discharging opening 22, be that the conveying of screw rod is reverse from charging aperture to discharging opening direction, hopper 3 is arranged on the machine barrel and with charging aperture 21 and is communicated with, 5 and eight mixing pans of conveyor screw cover are socketed on the screw rod 4 successively along throughput direction, there is certain interval between the adjacent mixing pan 6, on machine barrel 2 inwalls with mixing pan between partial fixing corresponding to gap be provided with some pins 23, the machine barrel top part corresponding with the conveyor screw cover is provided with medicine feeding hole (not shown in FIG.).Mixing pan 6 middle parts are provided with the installing hole 61 that adapts with the screw rod external diameter, and this mixing pan outer rim is evenly distributed with three combination tooths 62.Gap between the mixing pan 6 on one screw rod on 4 combination tooth 62 and another screw rod is relative, i.e. the setting of staggering of mixing pan on two screw rods.
During operation, motor 7 drive screw turns, coarse particles adds machine barrel by hopper from charging aperture simultaneously, enter the double-screw shaft delivery area that is provided with the conveyor screw cover, material is forced to move to the discharging opening direction from charging aperture, inject liquid from medicine feeding hole this moment in machine barrel, material enters successively the Dilvar zone of liquid and is provided with the high dense mixed zone of mixing pan.Chemical liquid pumps into Dilvar zone by the metering chemical feeding device metering.Realize high dense mixing of liquid and coarse particles in the dense mixed zone of height, per minute mixing number of times can be up to Nn (N--hybrid element circumference guiding gutter quantity n--revolution speed of screw), and this equipment is a kind of new and effective mixing device.
The present invention has adopted double-screw structure, so that the mixture operation efficient of blender was doubled more at least; Owing to being provided with pin at machine tube inner wall, further having strengthened mixed effect.
