Abstract

FIELD: chemical industry; agricultural, food and other industries; loose materials mixing.

SUBSTANCE: the invention is pertaining to the field of loose materials mixing and may be used in chemical industry, agricultural, food industry and other industries. The mixer has two stages of mixing. At the first stage the mixing is conducted with the help of working bodies with elastic components and at the second stage the loose material is moving at motion along the jigging chutes. The mixer is simple in design, has a high productivity and quality of mixing.

EFFECT: the invention ensures simplification of the mixer design, its high productivity and high quality of mixing.

Description

The invention is intended for mixing bulk materials and can be used in chemical, agricultural, food and other industries.

A known mixer of bulk solids of continuous action [RF Patent No. 2164868, BI No. 10, 2001, 28 C 5/08]. This device consists of horizontal elastic drums, nozzles for supplying components and unloading the mixture, a drive that includes an engine and gearbox, the shaft of which is connected by a coupling to the vertical shaft of the cross. The drums are mounted using rings on the discs, which in turn are directed to the hubs of the movable gears of the planetary bevel gear. The gears are mounted on the hollow horizontal axes of the crosspiece through sliding bearings. The fixed gear of the planetary gear is rigidly connected to the base, on which a clamping element is installed coaxially with the gearbox shaft, made in the form of a truncated cone with radial semicircular ledges in contact with the drums. Coaxial to the gearbox shaft is an annular storage hopper.

The disadvantages of this mixer are its low mixing efficiency.

Closest to the proposed mixer is a mixer of bulk solids of continuous action [RF Patent No. 2217305, BI No. 33, 11/27/03, 28 C 5/08], containing a stationary working chamber with nozzles for loading bulk components and unloading the product, inside of which on a vertical a shaft with a horizontal axis fixed to it fixedly mounted therein. The mixer consists of two sections located one below the other. On these axes, conical working bodies with elastic cantilever rods located vertices to the center, two in each section, are fixed on bearings. Gears are fixedly attached to these working bodies. A wide ring with teeth at the end, which engage with gears of working bodies, is fixedly fixed to the lid. The vertical shaft is fixed in the bearing assembly, which is attached to the bottom of the lower section.

The mixer operates as follows. Bulk materials are continuously filled from the funnel through the loading nozzle in the cover of the first section. The vertical shaft, rotating around its axis, moves the conical working bodies in a circle. The gears, engaging with fixed gear racks, are forced to rotate against the movement and the working bodies, thereby allowing the elastic cantilever rods toss the mixed materials forward and upward in the direction of movement. Mixed materials, flying up and up, hit the partitions and, falling down, again fall on the elastic elements of the working bodies. Thus, having passed almost a whole circle, the mixed materials through the slot hole fall into the second section, where the exact same process takes place. Having passed through the second section, bulk materials are discharged through a slotted discharge hole in the bottom.

The disadvantages of this mixer are its low mixing efficiency.

An object of the invention is to increase the efficiency of the process of mixing bulk materials.

The technical result is achieved in that in a mixer of bulk materials containing a housing, a cylindrical working chamber located inside its upper part, connected to nozzles for loading loose components and unloading a product, working bodies are attached to the vertical shaft, having elastic elements on the surface, made in the form brushes in contact with the bottom of the working chamber of a wave-like shape having a protrusion and vertical walls on both sides, the inside provided with an outlet associated with patras com unloading. In addition, under the working chamber there are gutters that can be rotated around an axis and equipped with damping devices.

The mixer of bulk materials contains a housing 1, a cylindrical working chamber 10 located inside its upper part, connected to the nozzles for loading bulk components 6 and unloading the product 5, a vertical shaft 4, to which the working bodies 2 are attached, having elastic elements made in the form of brushes on the surface in contact with the bottom of the working chamber of a wave-like shape 11 having a protrusion 7 and vertical walls on both sides. The inner wall of the working chamber is equipped with an outlet associated with the discharge pipe 5, under the working chamber there are grooves 9, which can be rotated around the axis and equipped with damping devices.

The mixer bulk materials works as follows.

Bulk materials to be mixed are poured from the nozzles of the loading of granular components 6 into the working chamber, where they are captured by six sequentially arranged working bodies 2 and moved along the wave-like bottom 11 to the discharge nozzle 5. In the process of moving materials, the elastic elements of the working bodies, in contact with the wave-like bottom, are deformed and , straightening in the hollows, they throw forward a part of the material. Due to the fact that the working bodies are arranged sequentially in the working chamber, they transfer all the bulk material to a suspended state and in turn direct the mixture to the outlet, and, passing through the protrusion 7, are cleaned. Next, the mixture enters the chutes 9, equipped with damping devices, which under the action of the mixture being poured on them make irregular rocking movements. Moving in the gutters and pouring from one to another, the mixture is subjected to additional mixing.

Thus, the use of the proposed combination of structural elements in the mixer can significantly improve the quality of mixing.
