(54) TOOLS FOR THE CONSTRUCTION OF VIBRATIONS OF SUSPENDED SUSPENSIONS IN THE BATH OF A SEPARATOR

S

The invention relates to the enrichment of minerals, and more specifically to devices for creating vibrations of a heavy suspension during the enrichment of minerals in wheel separators.

Superb supersonic and mechanical devices are used for oscillations of segmented the medium in a wide frequency range. High-frequency oscillations of the medium are created with ultrasonic generators. Low frequency oscillations of the medium are created with the help of diaphragms, moving sieves and other mechanical devices t J and 21.

The disadvantage of supersonic devices is the high consumption of necessary power, the absorption of high-quality vibrations by the medium, and the small amplitude of vibrations, which limits their field of application. In addition, the mesanic type devices are structurally complex, unreliable, and create large dynamical loads on the building structures.

It is also known a device for creating an oscillating movement of a heavy suspension, including a pneumatic valve, air ducts and an air compartment, made in the form of two chambers 3 symmetrically located relative to the longitudinal axis of the bath.

However, the known device does not provide sufficient accuracy for the separation of the material.

(ABOUT

The purpose of the invention is to improve the accuracy of separation of the enriched material by varying the magnitude of the oscillation amplitude of the suspension along the length of the bath.

The goal is achieved by

fS that each chamber of the air compartment is provided with an adjustable strap located across the entire slab of its inner wall.

FIG. 1 shows a device that resides; in fig. 2 - section A-A on. one.

The device consists of air chambers 1, built into the separator bath.

2 .. The chambers are connected to the pneumatic slide 3 via an air duct 4. The inner walls of the chamber 1 in the lower part are equipped with adjustable strips 5.

The device works as follows.

When periodic compressed air is supplied to chambers 1 by means of spool 3 via ducts 4, oscillatory movements of the suspension are formed in the working zone of the bath of separator 2.

The oscillatory movement of the suspension created by the pneumatic device increases the mobility of the material grains in the bath of the separator 2, changes the physical and mechanical properties of the suspension and improves the accuracy of separation. given density. With the help of adjustable strips on the inner walls of the air compartment chambers, the depth of the partition between the air and work compartments along the length of the separator's bath is changed. At the same time, the septum depth smoothly increases in the direction of material unloading. Consequently, the velonchin resistance to the movement of the suspension increases, while the intensity of the oscillations of the suspension increases with respect to the loading of the material. This contributes to improving the accuracy of its separation in a vibrating suspension.
