Description

The invention relates to devices for mixing dispersed media in order to obtain viscous homogeneous materials and can be used in various sectors of the economy.

The aim of the invention is to increase the intensity and productivity of highly viscous media.

The drawing shows a camera for mixing, General view.

The mixing chamber consists of a spring 1 and a spring 2 coaxially mounted with it. Springs 1 and 2 are fixed on the cover 3 and the bottom 4. In the middle part of the springs 1 and 2 ring mixing disks are fixed: in the spring 1 - disk 5, in the spring 2 - disk 6. A set of springs 1 and 2 is installed in the cup 7. The mixing chamber formed in this way is mounted on a vibrating stand that reports oscillations to the camera along its axis.

The natural vibration frequency of the spring 2 with the disk 3 due to the high stiffness of the spring and the small mass of the disk is 2-3 times higher than the forced oscillations created by the stand. The natural frequency of the spring 1 with the disk 5 due to the low stiffness of the spring and the large mass of the disk is 2-3 times lower than the forced frequency of the vibration stand. Thus, spring 1 with disk 5 has a pre-resonant setting, and spring 2 with disk 6 is resonant. As a result, springs and mixing discs oscillate out of phase: when disc 5 goes down, disc 6 goes up, and vice versa.

The camera operates as follows.

ί Several chambers for mixing can be installed on the table of the vibrating stand. When informing the table of the vibrostand of vibrations in the vertical direction, the chambers for mixing installed rigidly on the table of the vibrostand vibrate together with the table. Due to the setting of two oscillatory systems 2-6 and 1-5 for different operating modes (resonance and preresonance), the mixing disks 5 and 6 with the fixed springs 1 and 2 oscillate in antiphase. When the disk 5 moves up, the upper part of the spring 1 above the disk is compressed and the upper internal cavity of the spring 5 1 decreases; at the same time, the disk 6 moves down, the upper part of the spring 2 stretches and the upper internal cavity of the spring 2 increases. Below drives 5 and 6, the opposite is true. At the same time, 10 the medium to be processed is squeezed through the coils of springs from a decreasing volume to an increasing one. When mixing the disks in the opposite direction, i.e. in the second half of the oscillations, the processed medium is squeezed out in the opposite direction. In addition, the mixing medium is circulated.

High-frequency pumping of the processed medium from one cavity to another, circulation and the impact of oscillating turns of springs and mixing disks on it intensively destroy the structure of the medium and ensure uniform distribution of its components. The installation of several mixing chambers on a vibrating stand simultaneously increases the productivity of the mixing process.

The economic efficiency of using the proposed mixing chambers is achieved by increasing the intensity and productivity of mixing highly viscous mixtures.
