Abstract

The mixer contains a rotating drum 1, divided into sections 6 and 7 by a partition 2 with a slot 3 for overflow of material. Spiral guides 5 are installed inside the section. The loading chute 9 of the drum is connected through holes 10 and 4 in the end wall and the partition to the second section 7, and the discharge chute 12 is connected to the hole 10 in the end wall of the first section of the drum. 3 ill. 2 00 S O 00 Ј W

Description

The invention relates to mixers with a drum rotating around a horizontal axis and can be used to mix bulk materials and their mixtures with liquids in the oil refining, anode, electrode, construction and other industries

An object of the invention is to provide a compact mixer.

Figure 1 shows the proposed two-section mixer in section; figure 2 is a section aa in figure 1; on figs. -., section BB in figure 2.

The mixer comprises a rotatable drum 1, separated by a partition 2, having a slot 3 for overflowing material and an opening 4, into sections 6, 7, inside which spiral guides 5 are installed. The direction of curling of the spiral guides in sections b and 7 is opposite. On the extreme turn of the spiral guide section 7, a plate 8 is installed for transferring material from section 7 to section 6. From the same end of the mixer drum, a chute 9 for loading the processed material is installed, connected through a hole 10 in the end wall 11 and an opening 4 in the partition 2 with a second drum section 7, and a discharge chute 12 connected to an opening 10 in the end wall 11 of the drum.

The mixer operates as follows.

The components of the mixed Materials are metered in the required proportions and along the loading chute 9 through the holes 4 and 10 of the end wall 11 of the drum 1 and in the partition 2, min the first section, is fed to the central coil of the spiral guide of the second section of the mixer,

When the drum rotates, the material being processed, mixed on a spiral guide, moves to its extreme turn. At the extreme turn of the spiral guide plate 8 transfers the material to be processed through the slot 3 in the partition into section b. Since the direction of curling of the spiral guide of this section is opposite to the direction of curling of the guide section 7, the material begins to spiral upward to the central turn. When it reaches the central turn, the processed material through the hole 10 in the end wall enters the discharge chute 12.

The proposed mixer allows loading and unloading of material from one end of the mixer, while the maintenance will provide it with compactness and ease of use. Formula s A mixer comprising a rotatable drum with guides placed inside for mixing and moving material, 5 loading and unloading devices installed in the walls of the drum, a heater - often, in order to ensure the compactness of the mixer, the drum is equipped with a partition located perpendicular to its axis and dividing into two sections with a central hole, in each section there are guides made in the form of spirals with the opposite direction by the phenomenon of turns, a plate is installed at the 8th end of the peripheral turn at an angle greater than the angle of repose of the material, while the loading device is connected through a hole in the end wall and the partition to the second section, and the unloading device is connected to the hole in the end wall.
