Description

(54) REACTIVE VIBRATION GROUNDING

one

The invention relates to the building materials industry and is intended for filtering liquid masses.

A cone separator is known for gravitational enrichment of ores and sands of alluvial deposits, including an installed horizontally truncated cone, a distribution ring and a pulverized valve of the Segner wheel type, consisting of a receiving cylinder, flow tubes and a substation 1.

The disadvantage of the known device is a low degree of concentration, as a result of which the finishing of concentrates on other devices is required.

A centrifugal vibrating screen is known, including a body with a cylindrical screen vertically arranged therein, performing rotational and spatial oscillatory movements, a vibrator, systems for feeding the material to the sieve, removing the failure and cleaning the surface 2.

However, the known structure is characterized by insufficient efficiency of the process of percolating the liquid mass.

The aim of the invention is to increase the filtration efficiency and self-cleaning of the sieve.

The goal is achieved by the fact that

. the vibrator is designed as a rotating

5 under the action of the reactive forces of the hollow shaft of the distributor of the liquid mass with the unbalances installed at its ends.

FIG. 1 shows the proposed device, general view, longitudinal section; in fig. 2 - arrangement of blades

10 relative to the cylindrical screen.

A reactive vibrating screen, 1 case housing 1 with a sieve 2 coaxially fixed in it, inside which a hollow shaft 4 with unbalances is mounted on bearings 3

5 5. The shaft 4 at one end through the sealing device 6 is connected to the pressure hose 7 and is closed on the other side. On the shaft 4 are fixed hollow blades 8 with jet nozzles and cleaning blades 9. The blades 8 are connected by their

° Cavities with the cavity of shaft 4 and are arranged in such a way that together with the shaft they create a system of the Segner wheel type. Case 1 has nozzles 10 for removal of the finished product, and in the lower part is conical

failure collector 11, ending with nozzle 12 to remove failure. The whole system is suspended on elastic ring elements 13 to the base 14.

The device works as follows.

The source material under pressure of Gustunat on the N-7 to the cavity of the shaft 4, from where it goes into the cavity of the blades 8. From the jet nozzles of the blades 8, the material flows to the surface of the sieve 2 along the trajectories determined by the pressure in the system and the shape of the blades 8 Under the effect of the reactive moment acting upon the outflow of the material on the blades 8, the latter begin to rotate together with the shaft 4, the unbalances 3 and the cleaning blades 9, due to which the liquid mass evenly lies on the vibrating working surface sieves 2, cleaned from failure particles by cleaning blades 9. This allows to intensify the filtering process.

Under the action of the radial component of the centrifugal forces and vibrations, the conditioned material particles pass through the sieve surface and the product thus obtained is discharged through the nozzles 10. Vibration helps clean the sieve 2 cells from sticking failure particles.

Product

Failure by gravity and cleaning blades 9 is sent to the failure collector 11, from where it is removed through the nozzle 12. The ring-shaped elastic elements 13 allow the BearButTb system to oscillate spatially with respect to the base 14.
