Same-direction linear three-screw full-automatic production line for sealant

Abstract

The invention discloses a same-direction linear three-screw full-automatic production line for sealant, and relates to the field of chemical machine-sealant automatic production. The full-automatic production line comprises three screws, a speed change gear box, a side feeder, a vacuum buffer tank and a static mixer. The right end of the speed change gear box is provided with the side feeder, theside feeder is connected with a plurality of metering tanks at the upper end, the right end of the lower portion of the three screws is provided with the connected vacuum buffer tank, the right end ofthe three screws is sequentially provided with a condenser, a middle storage tank and the static mixer, and the condenser, the middle storage tank and the static mixer are sequentially connected through pipes, so that the three screws are sequentially divided into a feeding conveying zone, a kneading zone, a vacuuming zone, a vacuum kneading zone, a lowering zone, a splitting feeding zone and a dispersing conveying zone; and the same-direction linear three-screw full-automatic production line has the better diversion effect and more shearing time numbers, and therefore better distribution mixing and dispersion mixing are achieved.

Description

technical field [0001] The invention relates to the field of automatic production of chemical machinery-sealant, in particular to a full-automatic production line of three-screw sealant in the same direction. Background technique [0002] Most of the domestic sealant manufacturers basically pre-mix the polymer and powder in the kneader, high-speed disperser, and heating and stirring tank to remove water, then cool down to the planetary mixer and add additives and coloring materials to remove it before use. Packed in large barrels and then subpackaged. [0003] At present, a small number of manufacturers use twin-screw and static mixers for sealant production. Twin-screw extrusion is one of the most commonly used polymer processing methods. According to the relative rotation direction of the two screws, it can be divided into two categories: co-rotation and counter-rotation. The counter-rotating twin-screw extruder has stable extrusion and is mainly used for extrusion moldi...

Problems solved by technology

Therefore, when the output is increased, the too fast speed will lead to the weakening of the dispersion effect, which will inevitably lead to the increase of the length of the screw and the increase of energy consumption such as the heating of the barrel, the cooling of the refrigerator and the rotation of the motor.

In addition, when the amount of material is too large, the exhaust port is easy to "spray powder", and the vacuum port is easy to "spray", which affects the effect of exhaust and lowering.
