A multilevel mixer for electrolytes contains a housing of non-magnetic material, a source of magnetostatic field located from the outside of the housing, a system of ferromagnetic elements, moreover the ferromagnetic elements are rigidly fixed in the housing in parallel and perpendicular with magnetostatic field generated by the source of magnetic field. The invention provides the uniformity of mixing at macro- and microlevel, reduction of power consumption of the process.

Description

The invention relates to chemical, food, microbiological, etc. industries and can be used for uniform mixing of electrolytes at any dimensional level and in any volume.

Famous mixer | Av.sv. USSR Mo1754199, cl. УО1801Е13/08; published 15.08.92. Bul.MeZ0|, containing a source of a rotating electromagnetic field, inside which there is a working chamber made of non-magnetic material, which includes ferromagnetic elements located at the intersection of the chamber, which are made in the form of spherical bodies connected by flexible elements.

The disadvantage of this mixer is the complexity of the design, high energy consumption, as well as the fact that the mixing process occurs at the macro level.

Famous mixer for electrolytes | Dec. patent Me55792A, M.Kl. VOTE 13/08, pub. Bul. Мо4|, in the middle of which there is a working chamber made of non-magnetic material, which includes ferromagnetic elements, which are rigidly fixed in the housing parallel to the external magnetic field at a distance of two diameters of the ferromagnetic element.

The disadvantage of this mixer is that mixing is not possible at different dimensional levels, because the mixing process is carried out by ferromagnetic elements of a certain size.

The invention is based on the task of creating a multi-level mixer due to low material consumption, simplified design, reduced energy consumption of the process, ensuring uniform mixing both at the micro level and at larger dimensional levels, because the mixing will be carried out by each individual element of the system, which are located parallel and perpendicular to the external magnetic field and differ in size.

The task is achieved due to the fact that in a multi-level mixer for electrolytes, which contains a case made of non-magnetic material, the source of a constant magnetic field is located outside the case, a system of ferromagnetic elements, and the ferromagnetic elements are rigidly fixed in the case parallel to the constant magnetic field created by the source of the magnetic field. According to the invention, it contains additional ferromagnetic elements rigidly fixed perpendicular to the magnetic field.

Ferromagnetic elements have different sizes.

The size of the ferromagnetic element is determined by the dispersion of the particles of the electrolyte being mixed. Ferromagnetic elements can be needles, balls, cylinders, etc.

The causal relationship between the proposed features and the expected technical result will be as follows.

The process of mixing is used in many branches of industry - extraction of metals by microorganisms in biometallurgy, when obtaining metals from solutions by the electrolytic method or cementation, wastewater treatment, etc. At the same time, mechanical mixing, which is used during electrolysis and cementation, does not ensure uniformity in the entire volume, and in addition, does not ensure mixing at the micro level, which affects the quality of the metal. The application of ultrasonic mixing during electrolysis and cementation gives effects at the micro level, but does not ensure uniformity in the entire volume and, in addition, this method of mixing has a high cost.

Mixing electrolytes under the influence of a magnetic field will ensure uniformity at the macro and micro levels, and a system of ferromagnetic elements, which is located parallel and perpendicular to the magnetic field and has several levels of dimensions, will make it possible to mix electrolytes in any volume at the micron level.

The sizes of ferromagnetic elements and the ratio between the sizes at different levels, as well as the number of levels, depends on the specific technological process in which the electrolyte mixing process will be used. Mixing is ensured due to the fact that under the action of the external magnetic field, which is generated by the magnetic system, electrolyte flows occur in the vicinity of ferromagnetic elements, the distribution of velocities of which is the same along the entire length of each ferromagnetic element. The flow parameters depend on the size of the area and the material of which the surface of the ferromagnetic elements is made, the size of the external magnetic field, the pH of the medium and the number of levels.

Figure 1 shows a multi-level mixer, general view; in Fig. 2 - a multi-level ferromagnetic element, on which the arrow shows the direction of the permanent magnetic field.

The multi-level mixer consists of a body 1 made of non-ferromagnetic material, a magnetic system 2, a system of multi-level ferromagnetic elements C, which are rigidly fixed in the non-ferromagnetic body parallel and perpendicular to the external magnetic field, inlet 4 and outlet 5 of the mixed electrolyte. The system of multi-level ferromagnetic elements Z is parallel and perpendicularly arranged needles, cylinders, chains of balls, etc. at different levels 6, 7, 8.

The mixer works as follows.

The magnetic system 2, which creates a permanent magnetic field, and the system of ferromagnetic elements C form a single magnetic system. The electrolyte to be mixed enters the mixer through the inlet pipe 4 in the body 1. Due to the action of the external magnetic field, fluid flows occur in the vicinity of the ferromagnetic elements, which lead to the mixing process in the system of multi-level ferromagnetic elements 3. The mixed medium is discharged through the pipe 5.

The technical advantage consists in simplifying the design of the mixer, reducing the energy consumption of the process, ensuring uniform mixing both at the micro level and at larger dimensional levels, because the mixing is carried out by each individual element of the system, which are located parallel and perpendicular to the external magnetic field and differ in size.
