Large-flow combined granulator

Technical Field

The utility model relates to a large-flow combined granulator.

Background

Granite is a natural stone, belongs to rock pulp and is widely used for outdoor decorative surfaces of buildings. However, granite is very expensive in manufacturing cost, has public danger when being used as a decorative surface on an outer wall of a building, and is not easy to be used in a large-area or high-rise building outer wall body. Therefore, in order to achieve the luxurious appearance of granite for buildings, the materials for imitating granite are continuously coming out, the imitation process is very complicated due to the multi-color and multi-anisotropy of the granite, people need a simple imitation coating to simplify the complexity of the imitation process, and under the background, the colorful coating is produced.

The colorful paint is mainly applied to the imitation stone paint, so the colorful paint is also called liquid stone and also called imitation granite exterior wall paint. The paint is composed of incompatible two-phase components, one phase of dispersion medium is a continuous phase, and the other phase is a dispersion phase, and when the paint is coated, a luxurious, beautiful and colorful pattern can be obtained by one-time spraying. Since the multicolor paint has a certain toughness, it is required to be mechanically cut into pellets by a pelletizer.

The Chinese utility model with the bulletin number of 210753109U discloses a novel multicolor paint granulator, which comprises a feeding funnel, wherein the upper end of the feeding funnel is provided with a transverse plate, the lower end of the feeding funnel is provided with a first material cylinder, and a first stirring device extending into the first material cylinder is vertically arranged on the transverse plate; the second feed cylinder is located the oblique side below of first feed cylinder, and second feed cylinder middle part one side is equipped with the feeding pipeline perpendicularly, and the port of feeding pipeline is connected with the conveying pipeline, and conveying pipeline one end links to each other with first feed cylinder lower extreme, and second feed cylinder lower extreme is equipped with out the feed cylinder. Multicolor paint carries out the dispersion shearing granulation for the first time by first agitating unit in getting into first feed cylinder through the pan feeding funnel of this granulator, in the granulation is cuted in the dispersion for the first time through the charging conduit entering second feed cylinder through the charging conduit, is carried out the dispersion shearing granulation of the second time by second agitating unit, and the granulation is even unanimous for multicolor paint granulation is once taken shape, has improved granulation production efficiency. The utility model discloses a combined granulator does not relate to the concrete structure of agitating unit, feed cylinder.

As shown in fig. 1 to fig. 3, the mounting structure of the stirring device and the charging barrel of the granulator in the prior art is mainly composed of a motor 1, a lower charging barrel 2, a screw shaft 3 mounted inside the lower charging barrel 2, a transmission shaft 4, a rotary cutter 5 and a screen 6.
