Description

A device for separating material for crucible is known, comprising a cyclone xaiMepy with a 1pipe 01M drain, the bottom part of which is located in the chamber opposite the back pressure, and having a discharge nozzle and a drain connection.

The difference of the proposed device is that the drain nipple of the cyclone chamber is installed in its lower base, forming an annular gap for unloading sands, and the counterpressure chamber is polyethylene closed with an automatically adjustable drain.

This allows for the regulation of the separation size.

The drawing shows the described device.

It includes a cyclone iKaiMepy / with a drain nozzle 2. The lower part of the cyclone is located in the backpressure chamber 5, which has a discharge nozzle 4 and a drain nozzle 5. The nozzle 2 is installed in the bottom base of the 6. Cyclone chamber 1. The counter pressure chamber 3 is made closed with automatically adjustable A drain, for which the drain nozzle 5 is located | a valve 7, controlled by a regulator tor 8 through an additional mechanical mechanism | M 9.

In the cyclonic one. The measure 1. A sand fraction, moving with ino, was supported at the walls of the chamber, discharged through the annular gap formed by the chamber 1 and its lower base 6.

When the pressure in chamber 3 is increased, the amount of sand fraction decreases and the amount of discharge discharged through drain connection 2 increases, and consequently also the discharge flow. The pressure in chamber 3 is measured by a pressure gauge 11 and a regulator; it is measured by a valve 7.

Unloading of the thickened sand fraction is carried out through the nozzle 4. Valve 7 serves to adjust the back pressure in chamber 3. In the case where the desired counter pressure cannot be created by completely closing the valve 7, additional water is supplied to chamber 3. D pressure through vent.il 12.

The maintenance of the specified counter-pressure in the chamber 3 is provided by an automatic control system consisting of a Manometr / /, a regulator 8 and an actuator 9.

In order to prevent the air tube 13 from being provided in the cyclone chamber of an excessive vacuum, is connected to the atmosphere. a drain nozzle, the lower part of which is located in the backpressure chamber having a discharge nozzle and drain shubrubki, characterized in that, in order to adjust the separation ratio, 5 drainage: cyclone tatrum, the chamber is laid down in its lower base forming the collimated slit for unloading of yueskov, and the backpressure chamber is closed with an automatically controlled discharge.
