Description

(54) AIRWAY SEPARATOR

one

The invention relates to mineral processing equipment, in particular, to the construction of air-through-flow separators, and can be used in the enrichment of minerals and industrial wastes in non-ferrous metallurgy, electrical engineering, building materials and other areas of national economy.

An air-through-type separator is known, which contains a vertical section of the chambers of a rectangular section made in the form of knee-shaped sections with slits and a cross section that gradually increases in the direction of the air flow, loading and unloading nozzles, slots located on the upper inclined walls of the knee sections which are fitted with slides for adjusting the slots and discharge pockets 1J.

The location of the loading nozzle and the loading pockets at a certain height of the separation chamber reduces the ability to control the quality of the separated fractions at a certain air flow rate.

The closest technical solution for the function performed and the result achieved is an air-through separator that includes a housing with a vertical rectangular cross-section camera placed in it, increasing along Bbicotie’s chamber, made in the chamber walls, flexible plates installed opposite windows 2.

The disadvantage of this separator is that the material is loaded into the base of the separation chamber, i.e., the loading nozzle is fixed at a height of 1 hp of the hub of the chamber, which means that the tank has 6 || a5 dividing the Schedude in separation, and the presence of rotor elements on the existing inclined wall complicates the design.

The purpose of the invention is to expand the operational capabilities of the separator by increasing the accuracy of controlling the separation process.

This goal is achieved due to the fact that the loading and intermediate discharge pipes are mounted on flexible plates installed with the possibility of vertical movement, while the bottom surface of the loading pipe is hinged on the flexible plate, and the intermediate discharge pipe is equipped with a sector selector.

FIG. 1 is a diagram of the separator, side view in section; in fig. 2 is a cross section of the separator below the loading and intermediate discharge pipes.

The separator contains a vertical separation chamber 1, a loading nozzle 2, a lower discharge port 3 for unloading the heavy fraction, an intermediate discharge nozzle 4 and an upper discharge port 5 for diverting the light fraction. The separation chamber 1 is made of a rectangular cross section increasing in the upward direction. In the two opposite walls 6 of the chamber 1, installed at an angle relative to each other, preferably at an angle of 15 to 25 °, windows 7 are provided, made along the entire height of the walls b in the form of rectangles. In the walls b against windows 7, flexible movable plates are installed. 8, overlapping windows 7. One of the flexible movable plates 8 is provided with a charging nozzle 2 of rectangular cross section, and another is equipped with an intermediate discharge nozzle 4 of rectangular cross section. The loading nozzle 2 and the intermediate discharge nozzle 4 through rectangular slots in flexible plates 8 are enclosed by a cutting chamber 1. The plates 8 are tightly mounted in walls 9 fixedly attached to the walls b, and have the possibility of reciprocally moving along the walls b. To fix the position of the flexible movable plates 8, clamps 10 are provided, for example screw type (clamps of any type are possible). The bottom surface 11 of the loading nozzle 2 is rotatable in the hinge 12 relative to the movable plate 8. The hinge 12 is fixed on the plate 8. The intermediate unloading nozzle 4 is equipped with a sector selector 13 of the industrial product fraction, attached to the movable plate 8.

The separator works as follows. Through the separation chamber 1 passes from the bottom up a stream of air. The feed pipe 2 supplies the source material, which is divided into fractions in the upward air flow. The heaviest fraction is emitted through the lower discharge port 3, and the lightest - through

top discharge window 5. The intermediate fraction is released through the intermediate discharge pipe 4. To increase the quality of the separated fractions during the operation of the separator, the loading 2 and intermediate discharge 4 pipes installed on the movable flexible plates 8 move the cross-section: chambers 1 and secured with latches 10. The final adjustment of the quality of separation is made by rotating the bottom surface 11 of the loading pipe 2 and the sector selector 13 introduced into the chamber 1 p omezhutochnogo discharge pipe 4.

The proposed separator provides a wider operational capabilities compared with the prototype. Moving in height chambers, the loading and intermediate nozzles with a rotatable bottom surface of the loading nozzle and a sector selector of the intermediate nozzle improve the quality of the bottom product and intermediate product by more precisely controlling the separation.
