Abstract

The invention relates to the field of general mechanical engineering, in particular to devices for mixing particles, for example, feed components. The technical result is a paddle mixer that provides high uniformity of the finished mixture as a result of highly efficient mixing of particles and prevents the particles being mixed from the feed opening outward during the mixing process. the blade mixer contains a housing 1 with a loading hole 2 and a discharge hole 3, a support frame 4, a shaft 5 with blades 6, p fins 7, grilles 8 with holes 9 and visors 10, chippers 11 installed in the feed hole 2. The paddle mixer operates as follows. The components of the mixture are continuously charged into the interior of the housing 1 mounted on the support frame 4 through the feed opening 2. The drive drives the shaft 5 with the blades 6, the plates 7, the grilles 8 into rotation, as a result of which the mixed particles are raised high and scattered with the help of the rotating blades 6 and the plates 7, thereby mixing effectively in a twisted longitudinal-spiral motion. Further, through the holes 9 with the visors 10 of the grating 8, the mixed particles receive a transverse-spraying movement, which leads to highly efficient mixing. Then the mixed particles are again raised high and scattered with the help of rotating blades 6 and plates 7, thereby effectively mixing in a swirling longitudinal-spiral motion. Further, through the openings 9 with the visors 10 of the grating 8, the mixed particles again receive a transverse-spraying movement, which leads to highly efficient mixing.

Description

The utility model relates to the field of general engineering, in particular to devices for mixing particles, for example, feed components.

Known paddle mixer (RF Patent No. 120016, class B01F 7/00, 09/10/2012), consisting of a housing with a half-cylinder bottom and with holes for loading and unloading the product, a conical reflector located in front of the discharge hole, a shaft with blades in the form of plates with fixed and, if necessary, removable strokes on every second plate, the ends of which are bent and rounded in the direction opposite to the movement of the mixture with a gap of 3-5 mm between the strokes and the bottom of the body.

The disadvantage of this device is the discharge of the mixed particles from the loading opening to the outside during the mixing process.

The closest analogue, both in technical essence and in purpose, is a paddle mixer (AS USSR No. 778762, class B01F 7/04, 11/15/1980) made of a support frame, a housing with loading and unloading openings, a shaft with blades consisting of central and peripheral plates.

The disadvantage of this device is the low uniformity of the finished mixture, caused by the low efficiency of mixing particles.

The technical task is to develop a paddle mixer designed for highly efficient mixing of particles, ensuring high uniformity of the finished mixture and eliminating the ejection of the mixed particles from the loading hole to the outside during the mixing process.

The technical result is a paddle mixer, which provides high uniformity of the finished mixture as a result of highly efficient mixing of particles and prevents the discharge of mixed particles from the feed opening to the outside during the mixing process.

This is achieved due to the fact that in the paddle mixer there is a support frame, a housing with loading and unloading holes, a shaft, blades with plates, it is proposed to additionally provide the device with gratings with holes and visors to create a highly effective transverse-spraying movement of the mixed particles, and to provide the loading hole with chippers to prevent the ejection of mixed particles from the feed opening to the outside during the mixing process.

The device is illustrated by drawings, where in FIG. 1 shows a paddle mixer - side view; in FIG. 2 - sections aa, bb in FIG. one.

The proposed paddle mixer (Fig. 1, 2) contains a housing 1 with a loading hole 2 and a discharge hole 3, a support frame 4, a shaft 5 with blades 6, plates 7, gratings 8 with holes 9 and peaks 10, chippers 11 installed in the boot holes 2.

The paddle mixer operates as follows. The components of the mixture are continuously charged into the interior of the housing 1 mounted on the support frame 4 through the feed opening 2. By means of a drive, the shaft 5 is rotated with blades 6, plates 7, grids 8, as a result of which the mixed particles are raised high and scattered with the help of rotating blades 6 and plates 7, thereby mixing effectively in a twisted longitudinal-spiral motion. Further, through the holes 9 with the visors 10 of the grating 8, the mixed particles receive a transverse-spraying movement, which leads to highly efficient mixing. Then the mixed particles are again raised high and scattered with the help of rotating blades 6 and plates 7, thereby effectively mixing in a swirling longitudinal-spiral motion. Further, through the openings 9 with the visors 10 of the grating 8, the mixed particles again receive a transverse-spraying movement, which leads to highly efficient mixing. Then the mixed particles are again raised high and scattered with the help of rotating blades 6 and plates 7, thereby effectively mixing in a twisted longitudinal-spiral motion, and finally mixed in the discharge opening 3. The chippers 11 prevent the particles being mixed from the loading opening outward during the mixing process .

The proposed paddle mixer provides high uniformity of the finished mixture as a result of highly efficient mixing of particles due to the highly efficient transverse-spray movement of the mixed particles and prevents the mixed particles from ejecting from the loading opening to the outside during mixing due to the installation of chippers in the loading hole.
