Abstract

The invention relates to mineral processing and b. used in the washing of minerals containing large pieces of material and foreign objects. The goal is to increase the productivity of the tank by promptly cleaning the tank (P) and the standpipe (T). The device includes P 1 and an air-lift with a pressure T 8 and air-supply T 9 located in it. In P 1, there are opposite windows 2 and 4 for the inlet and outlet of the pulp. Windows 2 and 4 overlap with gates (W) 3 and 5. In addition, P 1 is equipped with a lid 6 with a valve 7 for WHO I Ikuchu / 5 air release and a vibrator 12 connected to the bottom of the YUR 1. The bottom 10 along the perimeter is made with an elastic connection with its walls and has a slope towards the discharge. At the same time, P I is made with a volume of more than one volume T 8. The volume of part P 1 between its lid 6 and the lower end of T 8 is equal to one volume T 8. From the wash tower 13 ore and foreign objects come through window 2 to P 1. At the same time W 3 is raised, W 5 is lowered, and valve 7 is closed. Then T 9 serves compressed air and through T 8 they discharge material from P 1. To remove large pieces of material and foreign objects from P 1 and purify T 8, they lower W 3, section P 1 from the internal volume of the tower 13. The air valve is opened 7 and release the pulp under its own weight from T 8 to P 1. Then lift W 5, turn on vibrator 12 and release pulp remains with large pieces of ore and foreign objects into tank 16. Vibration of inclined bottom 10 by vibrator 12 accelerates unloading P 1 from sticking large pieces. 2 Il. Air S (L ate N5 SD 00 00 Figure 1

Description

The invention relates to devices that are in the pressure pipe 8,

used in the tower when flushing in the same way and release it. Stop feeding

minerals containing large air through the pipe 9, raise the gate 5,

pieces of material and outsiders pre-open the window 4, include a vibrator 12

 methane, and can be used in and produce pulp residues with coarse iron, manganese and phosphate lumps and foreign objects in

capacity 16.

The vibration of the inclined bottom 10 of the tank 1 in the discharge direction accelerates

 release of cemented clay and sticking to the cleaning of the tank and the pressure head 10 at the bottom of 10 large pieces and side pipes

FIG. 1 shows the proposed device, a longitudinal section; in fig. 2 -

The aim of the invention is to increase the productivity of the tower at the expense of the operator, a top view.

but 4 with a gateway 5 for pulp production, a cover 6 with a valve 7, a pressure head 8 and an air supply pipe 9 of the airlift, an inclined bottom 10 with an elastic element. Secondly, in case of an emergency stop of the airlift, in the case when the pressure head 8 is overlapped and the lift The bullet contains tank 1, window 2 i stops over it. The cleaning of the pressure head with a gate 3 for the inlet of the pulp and ca. tube 8 is carried out as follows.

The gate 3 is lowered and the window 2 is closed, the air valve 7 on the lid 6 is opened, the air supply through the pipe 9 is cut off and the pulp is discharged under the action of the self 11 and the vibrator 12. tank 1.

by inclining the bottom of the washing tower; Exiting the discharge pipe 8; the bullets13 with the distributive installed below it displaces the air in the cutter system 14 and the nozzles 15 for the fan 1 under the cover 6, through the valve 7,

I serve in the tower air mixture. To occupy the volume between the cover 6 and the lower end of the pressure pipe 8, which

must be equal to one volume of the pressure pipe 8.

For normal operation of the device

between the sloping bottom 10 and lower

receiving pulp and foreign objects has a capacity of 16.

The tank is made with a volume of more than one volume of the pressure pipe, and the volume of the part of the tank between the lid and the bottom end of the pressure pipe is equal to one - about the end of the pressure pipe 8 must find the volume of the pressure pipe. Therefore, the entire volume of the reservoir. The device works as follows: 1 must be more than one volume.

discharge pipe 8. The larger the whole

From the washing tower 13 of the ore reservoir volume 1, the less foreign objects will come through stopping the operation of the tower for cleaning the window 2 into the tank 1. At this, the gate of the tank 1 and the discharge pipe 8 is raised, the gate of the head is 5, the valve 7 is oversized pieces and foreign objects, covered. Filling the tank 1, the pulp is exhausted. After the pulp is descended from the pressure pipe, the air in the tank 1 would have 8 in the tank 1 lift the gate 5, through the pressure pipe 8 and open the window 4 under the cover 6. open the vibrator 12 When the pulp in the tank 1, the overflows release the contents of the tank 1 into the lower end of the pressure pipe 8, it receives the receiving tank 16. continues to rise along it and partially in the tank 1, compressing the tower then, it is put into operation, between the pulp surface and the cover 6 closed air. Then a pipe 9 is supplied to the hedgehog valve 7, the gate is lowered 5, the drawn air, in the pressure pipe 8 forms the gate 3, opens the window 2, with the pulp air mixture, which provides the tank 1 with pulp and serves

compressed air through the pipe 9 into the pressure pipe 8.

The lifting of the washed product and its unloading from the tank 1 also contributes. Compressed air under the lid 6, which presses on the pulp surface in the tank 1, also contributes to this.

Cleaning tank 1 is necessary in two cases.

First, when it is necessary to clean the tank 1 from the large pieces of material accumulated in it and extraneous pre-compressed air through the pipe 9 into the pressure pipe 8.

Claims (1)

Invention Formula 50 A device for unloading a flushing tower, including a tank with windows opposite to each other for inlet and outlet of pulp, overlapped by slide valves, located in resermet. For this, the gate 3 is lowered, the airlift with the pressure head is exhausted and the window 2 is air-conditioned and the reservoir 1 is separated by supply pipes, characterized in that, in order to increase the productivity of the tower through operational cleaning from the internal volume of the tower 13. Putting air through the pipe 9, raise the pulmede with an inclined bottom 10 and lower  The end of the pressure pipe 8 must find the volume of the tank 1, the less it will have to stop the operation of the tower for cleaning the tank 1 and the pressure pipe 8 from large pieces and foreign objects. After descending the pulp from the pressure pipe 8 to the tank 1, they raise the gate 5 they turn on vibrator 12 and release the contents of tank 1 into receiving tank 16. Then the tower is put into operation, for this they turn off vibrator 12, close valve 7, lower gate 10, lift gate 3, open window 2, fill tank 1 with pulp and serve compressed air through the pipe 9 into the pressure pipe 8. Invention Formula the tank and the pressure pipe, the tank is equipped with a lid with a valve for air release and an inlet connected to the bottom of the tank, this bottom of the tank is made with an elastic meter with an elastic connection to its walls and inclined in the direction of discharge, and the tank is made with a volume of more than one volume of the pressure pipe, and the volume of the part of the tank between its cover and the lower end of the pressure pipe is equal to one volume of the pressure pipe.
