SU1523166A1 - Arrangement for separating metallic impurties from the flow of process compound - Google Patents

Abstract

This invention relates to the purification of a process mass stream from metallic impurities (MP). The goal is to increase the efficiency of the technological mass purification process from MPs by eliminating their entry into the final point. The chamber 1 of the device is divided in the lower part by a partition 2 into two adjacent cavities 3 and 4. The cavity is intended for the final product cleaned from the MP, and the cavity 14 is for the part of the source material containing the MP. In the chamber 1, a flap 5 is arranged in the form of a conical funnel facing a large opening to the metal detector 6. The flap 5 drive mechanism is designed as an electromagnet (EM) with a rotary shell, which is rigidly connected with it. The valve 5 is installed with the possibility of rotation relative to fixed in the opposite walls of the chamber 1 horizontal elastic elements. Anchor set coaxially with elastic elements. The technological mass enters through the metal detector 6. When the device is turned on, the EM is triggered, the measles takes a horizontal position and sets the flap 5 to a position where the initial mass enters the cavity 3. When an MP is detected by the metal detector 6, the EM is disconnected. Due to the elasticity of the elastic elements, the valve 5 returns to a vertical position and part of the mass flow from the MP enters the cavity 4. After a short time, the EM is activated, the valve 5 again directs the flow of the technological mass into the cavity 3. 1 Cp. f-ly, 3 ill.

Description

The invention relates to the separation of materials according to magnetic properties and can be used when cleaning the technological mass from metallic inclusions.

The purpose of the invention is to increase the efficiency of the process mass cleaning process from metal impurities by eliminating their entry into the final product.

Figure 1 presents the device, a General view, in section; figure 2 - section aa in figure 1; on fig.Z - section bb in figure 2. ,

The device contains a camera 1, divided in the lower part of the partition 2 into two adjacent cavities 3 and 4.

The first cavity 3 is designed to collect the main, non-metallic impurities stream of those 0

the second mass, and the second 4, for a part of the flow, containing metallic impurities.

In the chamber 1 there is a rotary damper 5. A metal detector 6 is installed above the chamber, designed to detect metallic impurities in the mass flow.

The metal detector 6 is connected to the drive mechanism 7 of the shutter 5. The second is placed above the cavity 4, designed to collect part of the stream containing metal particles, and is made in the form of a shell suspended on two elastic coaxial elements 8 in the form of springs torsion The ends of each of the springs are fixed on opposite walls 9 and 10 of the chamber 1 and the flap 5.

The valve 5, when the device is operated, rotates at a certain angle oi and occupies a position (Fig., Point), located above the cavity 3, intended for collecting the main flow.

The drive mechanism 8 is implemented as an electromagnet with a rotary wheel 11 mounted coaxially with elastic elements 8 and rigidly connected to the rotary valve 5 by means of a stud 12,

The coils 13 of the electromagnet and part of its core .14 placed in a sealed casing 15.

The device works as follows.

When voltage is applied, the metal detector 6 is prepared and enters the tracking mode, and the electromagnet triggers and rotates the bark 11 and the associated valve 5 at a certain angle, and the valve 5 occupies the position (shown by a dotted line) above the cavity 3 intended to collect the main , not containing metallic impurities, technological mass flow,

The technological mass from a bunker (not shown) under its own weight enters the metal detector 6, in which this mass is monitored and metallic impurities are detected in it. If there are no metal primes in the flow, then from the metal detector 6, through the gate 5, the technological mass enters the cavity 3,

In the presence of metal impurities from the metal detector 6, an electronic unit (not shown) receives a signal to turn off the electromagnet of the drive mechanism 7. The electromagnet releases the measles 11. The last and associated valve, under the influence of torsion springs 8, returns to its original state, wherein the valve 5 is located above the cavity 4 and a part of the stream containing metallic impurities passes into this cavity,

In the absence of repeated signals from the metal detector 6, an electromagnet with a time sufficient to pass through part 5 of the stream containing metal impurities through valve 5 and the valve 5, together with the bark, rotates at the angle and moves again above the first cavity 3, moving here is the main thread. The process is repeated many times.

In the event of a sudden disappearance of supply voltages or other malfunctions in the circuit, the electromagnet 7 releases the measles 11, the latter and the damper under the influence of the springs 8 return to their initial state, and the technological mass moves through the damper into the cavity 4 designed to collect metallic impurities,

Thus, in emergency situations in the proposed device, mixing of the separated parts of the stream is prevented, thus ensuring the safety of use of the final product,
