Description

The invention relates to a device for producing mechanical vibrations using electromagnetism and can be used in various technological processes for processing (activation) of liquids and solutions by means of a vibro-jet magnetic effect, accompanied by a change in the properties of liquids and solutions.

Known vibro-jet mixer and diluent (RU 2208474 C2, MPK7 B01F 13/08, publ. 07/20/2003), comprising a housing, an electromagnetic vibrator, separated by a baffle from the working body in the form of several plates spring-loaded with flat springs with horseshoe-shaped trapezoidal openings, which are the anchors of the electromagnets vibroprop , each of which is installed on the other side of the partition opposite the magnetic circuit. The distance from the partition to the anchors is no less than the amplitude of the oscillations of the anchors in a liquid medium with a natural frequency equal to the frequency of the supply voltage of the electromagnetic vibrator. The casing is made in the form of a regular polygonal prism. Each plate is located on the edge of the housing and is mounted on the larger shoulder of the spring, made in the form of an asymmetric semicircular bracket, and the ratio of the length of the larger shoulder of the spring to the radius of its curvature should be at least three.

The disadvantages of this device are the low efficiency of processing liquids due to the significant turbulence of the jets and a rather narrow scope due to the difficulty of providing a resonant mode of operation in liquids with different densities.

A device for vibro-magnetic magnetic activation of liquids and solutions (RU 2275956 C2, IPC B01F 13/08 (2006.01), publ. 10.05.2006), which is selected as a prototype, containing a housing in the form of a regular polygonal prism, an electromagnetic actuator, separated by a partition from the working an organ made in the form of several spring-loaded activator plates with a trapezoidal circular hole, each of which is installed on the other side of the partition opposite the magnetic circuit, oscillating in a liquid medium with its own frequency th equal to the frequency of the supply voltage of the electromagnetic vibrator. Each activator plate is made in the form of a conical disk with a circular trapezoidal hole, has a conical jet former in the central part, and has peripheral openings located symmetrically with respect to the longitudinal axis.

The disadvantage of this device is the low processing capacity (degree of activation) of liquids and solutions due to a decrease in the total flow rate of the liquid due to squeezing part of the liquid from under the activator plates in the direction opposite to the main stream. The degree of activation in this case is proportional to the flow rate of the main fluid flow passing through the trapezoidal holes in the activator plates.

The objective of the invention is to increase the performance of the activation of liquids and solutions.

The problem is solved due to the fact that the device vibro-magnetic magnetic activation of liquids and solutions, as in the prototype, contains a housing in the form of a regular multifaceted prism, inside of which there is an electromagnetic actuator, activator plates that are located outside the housing on each of its side faces with a gap opposite the magnetic cores and mounted on the springs on the base of the housing, with each activator plate made in the form of a conical disk with a circular trapezoidal hole.

According to the invention, at least five consecutive concentric recesses with a width of at least 1.5 mm are made on the periphery of the surface of each activator plate facing the side face of the housing. One slope of each recess, from 0.4 to 0.5 mm deep, is made at right angles to the surface, and the other slope is made with a slope from the center of the activator plate.

The use of the proposed device for vibro-magnetic magnetic activation of liquids and solutions containing activator plates on a surface facing the side face of the housing, which are made of at least five concentric recesses with the above dimensions, provides an increased flow rate of the main fluid stream in comparison with the prototype, thereby increasing activation performance.

In FIG. 1 shows the design of the proposed device vibrojet magnetic activation of liquids and solutions; in FIG. 2 - a scaled-up region between the side face of the housing and the activator plate; in FIG. 3 is a view of the plane of the activator plate facing the side face of the housing.

The device vibro-magnetic magnetic activation of liquids and solutions (Fig. 1) contains a housing 1 made in the form of a regular multifaceted prism (in the example, a quadrangular), inside of which there are magnetic circuits 2 of an electromagnetic drive, 3 coils of electromagnets. Outside of the housing 1, on its side faces opposite the magnetic circuits 2, there are a gap with activator plates (anchors) 4 in the form of conical disks with a circular trapezoidal hole 5. The activator plates 4 are mounted on the larger shoulder of the springs 6, the smaller shoulder of which is mounted on the supports of the housing 1 7. Coils 3 through cable 8 are connected to a source of rectified AC voltage.

On the surface of each activator plate 4, facing the lateral face of the housing 1 (surface B), at least five consecutive concentric recesses 9 (Fig. 2, 3) are made with a width of at least 1.5 mm, with one slope, from a depth of 0, 4 to 0.5 mm, made at right angles to surface B, and the other slope is made with a slope from the center of the activator plate.

The device vibro-magnetic magnetic activation of liquids and solutions works as follows. The device is completely immersed in a liquid (solution). On the coil 3 of the electromagnets 2 of the electromagnetic actuator from the voltage source through cable 8 receives a rectified single-phase AC voltage. Upon receipt of a positive half-wave of AC voltage to the coils 3, current flows through them, the activator plates 4 under the influence of electromagnetic force are attracted to the poles of the magnetic circuits 2, moving to the side faces of the housing 1, the springs 6 are deformed. In this case, the liquid located between the activator plates 4 and the side faces of the housing 1 is expelled under excessive pressure through circular trapezoidal holes 5 in the direction from the housing 1, forming the main flow 10. Concentric recesses 9 made on the surface B of the activator plates 4 facing to the side faces of the housing 1, prevent the formation of the oncoming duct 11, thereby increasing the flow rate of the main fluid stream 10.

In the absence of a positive half-wave of voltage, no current flows through the coils 3, the electromagnetic force is zero, the activator plates 4, under the action of the spring force 6, move away from the side faces of the housing 1 and the next fluid volume flows under the activator plates 4.

With a constant supply of voltage to the coils 3, the activator plates 4 oscillate, forming a constant main fluid stream 10 with an increased flow rate, thereby activating it with greater productivity.

An increase in the performance of activation of liquids and solutions occurs due to an increase in the total flow rate of the main fluid flow 10, due to the practical absence of the counter flow 11. The counter fluid flow in the absence of concentric recesses 9 on the plane B of the activator plates 4 is formed when the platinum activators 4 move towards the side the faces of the housing 1 due to excess pressure under the activator plates 4, while reducing the flow rate of the total flow 10 and, accordingly, the activation performance. Successive concentric recesses 9 made on the surface B of the activator plates 4 facing the side face of the housing prevent the formation of an oncoming duct 11, thereby increasing the flow rate of the main fluid flow 10. As a result of the experiments, it was found that a significantly fixed effect of an increase in the flow rate of the main fluid flow ( not less than 10%) is achieved when the number of recesses 9 is not less than five with a depth of 0.4 to 0.5 mm and a width of at least 1.5 mm. The depth of the recesses of less than 0.4 mm does not have a significant effect on reducing the oncoming flow. Recesses with a width of less than 1.5 mm and a depth of more than 0.5 mm can cause turbulence in the main stream 10, which reduces the total liquid flow.

The proposed device vibro-magnetic magnetic activation of liquids and solutions, providing increased activation performance, can reduce energy consumption.
