RU2242272C2 - Aggregate for mixing of loose materials - Google Patents

Abstract

FIELD: agroindustrial complex and production of building materials; chemical industry.

SUBSTANCE: the invention is intended for use in agroindustrial complex, chemical industry, production of building materials and other branches of economy. The aggregate for mixing of loose materials contains batchers and a mixer. The mixer is composed of a body with a branch-pipe for the material discharge and a located in the body shaft with curvilinear blades fixed on it. The blades have windows and are equipped with deflecting elements located in the upper part of each blade. Above the body of the mixer there are two barrels with parallel shafts, the surface of one of the barrels, which is supplied with a rotary drive, is equipped with radial elastic elements. At that between the barrels and the body there is a guiding tool made in the form of a funnel. Such aggregate is simple in design, has high productivity and good quality of mixing and availability of the rotating deflecting element prevents sticking of the material.

EFFECT: the invention ensures simplicity of aggregate design, high productivity and good quality of mixing and availability of the rotating deflecting element prevents sticking of the material.

Description

The invention is intended for use in agriculture, the chemical industry, the production of building materials and other industries.

A known mixer of bulk materials containing dispensers, a hopper, a mixing chamber, in the form of two vertical conveyors, between which are successively mounted paddle drums that interact with the conveyors, and drives. [RF patent No. 2146965, BI No. 9, 2000, IPC 6 A 01 C 1/00]

The disadvantages of this device include the design complexity, high energy costs for driving drums and conveyors.

Closest to the proposed invention is an aggregate for mixing bulk materials containing dispensers, a mixing device in the form of a blade shaft located in the housing, a conveyor belt [RF Patent No. 2132723, BI No. 19 1999, IPC 6 A 01 C 1/00]. The disadvantages of this device include friction of the blades on the tape, leading to rapid wear of the tape, the difficulty of ensuring the complete withdrawal of material from the tape, the adhesion of the material prone to adhesion on the inner surface of the housing.

The objective of the invention is the creation of an aggregate for mixing bulk materials, prone to adhesion, a relatively simple design that provides high mixing efficiency with low energy costs.

The task is achieved by the fact that in the aggregate for mixing bulk materials containing dispensers, a mixing device consisting of a housing located in the shaft housing with curved blades mounted on it, the blades have windows and a fencing element is attached to the blades in the upper part, and above the housing two drums with parallel axes are placed and on the surface of one of them equipped with a rotary drive, there are radial elastic elements, and a guide mustache is placed between the drums and the body funnel triad.

High mixing efficiency is achieved by the fact that the mixing process is divided into two phases: the coarse mixing phase - between the two drums and the thin mixing phase - in the blade apparatus. Power consumption for the drive is small. Due to the fact that the blades are made curved and have windows, the travel time along the blades and the quality of the mixture during the transition of the mixture through the windows from one blade to another have increased. Due to the fact that the baffle element is made rotating, material sticking is excluded, and the mixture is sent directly to the mixture discharge pipe.

Figure 1 shows the unit for mixing bulk materials.

Figure 2 presents a section aa.

The unit for mixing bulk materials contains a housing 1 with a funnel 2. In the housing 1 there is a vertical shaft 3 with a horizontal flange at the end on which curved blades 4 are mounted, a baffle element 5 is mounted in the upper part of the blades. The shaft 3 is connected to the rotary drive 11. A smooth drum 6 and a drum 7 with elastic radial elements 8 on its surface, equipped with a rotational motion drive 12, are placed above the funnel. The materials are supplied by dispensers 9 and 10. In the lower part, the housing 1 has an outlet pipe narrow mixture 13.

Unit operation.

The mixed materials from the dispensers 9 and 10 are fed between the drums 6 and 7. The elastic elements of the drum 7, the components are captured and sprayed into the funnel, while rough mixing is carried out. From the funnel, the mixed components fall into the center of the shaft flange 7 and are thrown onto curved blades under the action of inertial effects. The material moves along their surface, part of the material passes from the blade to the blade through the windows, and part moves along the blade, then the material is sprayed, hits a rotating chipper, bounces and moves to the discharge pipe of the mixture, with intensive mixing of the material.

This unit for mixing bulk materials, with a simple design and low energy costs, has high performance and mixing quality. The unit is easy to maintain and repair.
