Description

f. 13

The invention relates to the filtration of liquids and gases, can be used in the hydraulics of general engineering and is an improvement of the device according to the author. No. 1153949

The purpose of the invention is povapenie reliability in operation and an increase in gr - the capacity of the filter element.

The goal is achieved by the fact that the partitions are made with needle spikes, and the filter element has a length and porosity of the material correspondingly increasing and decreasing in the course of movement of the medium being cleaned.

The drawing shows the filter.

The filter consists of a housing 1 with entrance 2 and output 3 holes, inside of which are mounted baffles 4 and 5 parallel to each other with deformed filter elements 6 placed between them. Partitions 4 and 5 are alternately placed at one of their ends 7 and 8 in the walls 9 and 10. The housing 1, and the other ends 11 and 12 are located at a certain distance from the walls of the housing 1.

The partitions 4 and 5 are made with spikes 13 attached vertically to the surface of the partitions dividing the case in height into separate sections 14.

The degree of deformation of filter elements can be increased along the course of the medium being cleaned, and the average cell size

reduce. . The filter works as follows

When assembling, the spikes 13 are inserted into the surface of the filter elements 6, which at the same time withstand increased differences (3-10 times larger than with the installation without spikes), which increases the reliability of the filter.

If the degree of deformation of the filter elements increases along the medium being cleaned or reduce the average cell size of the material of the filter element,

filtering particles and their deposition in various filter elements along the medium being cleaned. This contributes to the uniform filling of the filter elements with a polluter, reducing the pressure drop across the filter and increasing its dangerous capacity, which ultimately increases its reliability in operation. The filter works as follows.

Liquid contaminated with solid particles is fed through the inlet 2, and the liquid flow abruptly changes its direction, since the next hole for the passage of liquid is located on the opposite side between the end 11 of the partition and the vertical wall of the housing 1. As a result, inertial forces act on the solid particles, throwing them into the peripheral stagnant zones in which the accumulation of sediment occurs. The magnitude of the inertial forces acting on solid particles is due to the change in the velocity vector of the fluid flow in the direction and magnitude at the points of the bend flow. In the middle of the flow rate is significantly lower than at the entrance and exit

through the gaps between the walls and the vertical walls of the housing 1.

As the material of the filter elements 3, an elastic porous material of an open cell structure is used, for example, based on polyurethane, which has a very low flow resistance compared to other materials (fibrous, granular), partitions constitute 4-5% of its volume. However, if the filter element is not made of a single sheet material of a continuous strip fixed in the housing 1 at the inlet, but as separate filter elements arranged alternately in the filter compartments (sections), then at excessively high flow rates and fluid pressure, and some level of saturation of filter elements with solid particles, when the resistance to the passage of fluid increases, the strength

the friction between the surface of the filter elements and the partitions is less than the horizontal component of the flow force and the filter elements are shifted in the course of the outflow of fluid.

To eliminate this phenomenon, partitions 4 and 5 are equipped with spikes 13, capable of holding filter elements 6 not only in laminar, but also. turbulent flow of fluid. The filter elements can be made with different cell sizes and are installed in such a way that the material with larger cell sizes is in the first sections of the filter.

pa along the surface being cleaned. In this case, it is possible to control the degree of filtration of the liquid over a wide range. If filter elements made of the same material are deformed with different degrees (smaller in the first sections and larger in the latter), the cell size in the filter elements is consistently reduced and the degree of purification of the liquid is regulated over a wide range.
