Description

The invention relates to foundry and can be used to make mixtures, suspensions, and paints from liquid, pulverized, and granular materials.

The purpose of the invention is to simplify the design.

FIG. 1 shows the mixer, frontal section; in fig. 2 shows section A-A in FIG. 1 (planetary gear).

In the housing 1 through the bearing, the shaft of the carrier 2 is fixed, having a belt drive 3 from the electric motor. A gear wheel 4 is fixed in the housing, which, through gear 5, when rotating the carrier 2, transmits rotation to gear shaft 6, the mixing chamber is fixed to it in the form of a bowl-shaped part 7 and covering it from above and outside of the shell 8. Counterweight 9 is designed to reduce vibration when operating the mixer. Stationary boot device (pipe) 10 passes through the hollow shaft drove 2 into the mixing chamber.

When preparing the mixture, the mixer is set in motion and evenly load the components through pipe 10. The mixture under the action of the forces acting in the chamber: centrifugal, planetary rotation, Coriolis, gravity and friction is actively mixed, flows through the top of the bowl 7 into the shell 8 and further mixing goes between the outer wall of the bowl and the inner wall of the shell. From the bottom of the shell, the mixture is thrown into the housing 1, from where it is sent to the consumer.

As a result of the counter-rotation of the carrier and the mixing chamber, the mixing effect is enhanced, homogeneous mixtures are produced. The weight and placement of the counterweight are selected based on the nominal load of the mixer.

The operation of the mixer was modeled using a bowl-shaped container 50 mm deep and 260 mm in diameter, overlapped with organic glass. The container was fixed on a planetary rotating shaft. The carrier was driven from a DC motor with a frequency of 400 rpm. Mechanical transmission increased the speed of rotation of the planetary shaft by 3 times. The distance between the axis of the carrier and the planetary shaft is 80 mm. Direction of rotation and shafts oncoming. In the tank poured water in the amount of 0.5 volume.

lagged in the area of the bowl furthest from the axis of the carrier, i.e., it rotated relative to the bowl at a speed of 2n. Observation of the float placed in the tank showed a linear velocity of the surface of the liquid, equal to 2 agp-0,105, where r is the radius of the capacitance, 7-0.9 is the coefficient.

The mixer of the proposed design has technological advantages compared with the known, but simpler design. A feature of the device is the ability to reliably isolate the mechanical transmission from the aggressive action of the mixing components. The mixer has a quick-release working body of simple configuration. The mixer is set in motion from one engine. Technical effect

from the mixer of the proposed design is expressed in a simpler and more reliable device, the rapid preparation of homogeneous mixtures.
