Abstract

The invention can be used in technological processes for the preparation of mixtures of bulk materials, improves the quality of mixing and expands the scope of application. The mixer is made of a vertical box-shaped body 4 consisting of sections. Each section includes working bodies 5, trapezoidal reflectors 6 and pitched boards 7. The working bodies of adjacent sections are mutually perpendicular. The sloping boards 7 form rectangular exit slots. The major axis of each slit is parallel to the underlying working bodies. The reflectors 6 are installed above the pitched boards 7 with a slope smaller than that of the boards. 4 il.

Description

The invention relates to mechanical engineering and can be used in technological processes for the preparation of mixtures of bulk materials such as sand, ash, cement, gypsum, crushed stone, grain, flour, clay, and so on.

The purpose of the invention is to increase productivity, mixing quality and expand the scope.

FIG. 1 shows a mixer, a general view; FIG. 2 shows a section A-A in FIG. 1} in fig „3 - section bb in fig„ 1; in fig. 4 - mixing process in one section.

The mixer includes a hopper 1 with inclined 2 and vertical 3 walls, a housing 4 mounted under the hopper, working bodies 5 attached to the walls of the housing, trapezoidal reflectors 6 and pitched boards 7 attached to the housing and forming a rectangular slot in the lower part. Case 4 with a square cross section, working bodies 5, reflectors 6 and pitched boards 7 form a section. Under the upper section are similar sections, but with the direction of the working bodies perpendicular to the previous one.

 The mixer works as follows.

Into the hopper 1, the components of the mixture are fed in a continuous flow, which are connected with an inclined 2 and vertical 3 walls into a narrow flow, while the inclined walls 2 allow changing the performance of the mixer. The material flow leaving the slot of the bunker 1 falls on the working bodies 5. Each working body is separated.

The part of the flow above it is divided into two equal parts (Fig. 4), and the located parts are collected into separate flows, which in turn fall into the lower located working bodies and are also divided into two parts, then the located flows fall on the working bodies of the third row and they are separated, and then the connection of the parts of the flows. In the central, after the third row of working bodies, the material contains seven different parts of the flow (abbwvgd and bgdgde). The flows reach the walls of the body 4 also fall down and with the help of reflectors 6 are sent to the middle of the bottom of the section. in streams. Pitched boards 7, located perpendicularly relative to the working bodies, directed - Pt extreme sides of the streams to the exit slit.

Thus, the mixing of the mixing mixtures in the first section occurs in the process of dividing the total flow into parts and joining the various parts into new flows, and then the connections of all flows in the lower part of the section, and the extreme Parties of the flows are connected to its central parts. in parts

From the first section, the material enters the second, in which the material flows are mixed to a plane perpendicular to the previous one. Then the flow of material falls sequentially into the third and fourth sections,

where the mixing process is similar. From the exit slit of the fourth section comes the mixture.

The proposed solution will expand the range of application of mixers for the preparation of mixtures of various bulk materials, improve process performance,

Since the mixing speed approaches the free fall rate, the process’s energy consumption is significantly reduced, since energy is spent only on raising the raw materials into the bunker and there are no moving parts in the mixer design.
