Description

A kind of device for storing liquid

Technical field

A kind of device for storing liquid relates to the device for storing liquid that stores clear liquid and muddy liquid in a kind of many stoves of the Ka Er of being specially adapted to selenium absorption liquid circulation and the purification process simultaneously.

Background technology

At present, " the many stoves of Ka Er-selenium reclaims " PROCESS FOR TREATMENT copper anode muds that many employings both at home and abroad are advanced, because containing a large amount of dust in the flue gas enters and causes gathering dust the facility frequent jams in the selenium absorption liquid, filtration facility and corresponding device for storing liquid have been increased for this reason, one of them storage tank stores clear liquid, uses for the dust collecting system spray, and another storage tank stores muddy liquid, link to each other with filtering equipment, whole set of installation forms a closed cycle.In use the size of filter velocity and the quantity of slag is inversely proportional to, and along with the increase clear liquid feed speed of time does not catch up with the speed of dust collecting system spray, causes the solution of system can't balance, thereby causes the damage of pump class facility and the reduction of selenium absorption efficiency.

Summary of the invention

The purpose of this utility model is exactly in order to overcome above-mentioned problems of the prior art, provides a kind of and can store clear liquid and muddy liquid simultaneously, effectively avoids improving the device for storing liquid of selenium recovery system selenium absorption efficiency because volume causes the pump apparatus damage inadequately.

For achieving the above object, the utility model by the following technical solutions.

A kind of device for storing liquid is characterized in that the structure of this device comprises:

Outer tank body, this tank body are the tank body of a sealing, and its top sealing plate is provided with compressed air inlet, clear liquid import, muddy liquid import, access hole; The tank base sidewall is provided with a muddy liquid outlet, a purified liquor outlet;

Built-in reservoir, this reservoir are to be positioned at the upper end uncovered cell body of seat at the bottom of the outer tank body, and its cell body sidewall is provided with a clear liquid exhaust tube, and this exhaust tube connects with the purified liquor outlet of outer tank body;

The clear liquid feed tube, this feed tube by the clear liquid import that outer tank body top sealing plate is provided with enter, the lower end is positioned at built-in reservoir;

Compressed air inlet pipe, this air inlet pipe by the compressed air inlet that outer tank body top sealing plate is provided with enter, the lower end outside bottom between inner tank wall and the built-in reservoir outer wall.

A kind of device for storing liquid of the present utility model, the height that it is characterized in that described built-in reservoir are 2/3 of outer tank body jar inner height.

A kind of device for storing liquid of the utility model can store clear liquid and muddy liquid simultaneously, and the pump apparatus of having avoided can't balance causing because of system bulk damages, and has reduced labour intensity, has improved the selenium absorption efficiency.Have characteristics simple and reliable for structure, that floor area is little, practical, with low cost.

Description of drawings

Fig. 1 is structural representation of the present utility model.

The specific embodiment

A kind of device for storing liquid, the structure of this device comprises: outer tank body 1, this tank body are the tank body of a sealing, and its top sealing plate is provided with compressed air inlet 2, clear liquid import 3, muddy liquid import 4, access hole 5; The tank base sidewall is provided with 6, purified liquor outlets 7 of a muddy liquid outlet; Built-in reservoir 8, this reservoir are to be positioned at the upper end uncovered cell body of seat at the bottom of the outer tank body, and its cell body sidewall is provided with a clear liquid exhaust tube 9, and this exhaust tube connects with the purified liquor outlet of outer tank body; Clear liquid feed tube 10, this feed tube by the clear liquid import that outer tank body top sealing plate is provided with enter, the lower end is positioned at built-in reservoir; Compressed air inlet pipe 11, this air inlet pipe by the compressed air inlet that outer tank body top sealing plate is provided with enter, the lower end outside bottom between inner tank wall and the built-in reservoir outer wall; The height of described built-in reservoir is 2/3 of outer tank body jar inner height.

A kind of device for storing liquid of the present utility model, outer tank body can adopt the PPH material to make, and the tank deck sealing is reserved with compressed air inlet, clear liquid import, muddy liquid import, access hole, a muddy liquid outlet, a purified liquor outlet, the built-in reservoir of a built-in opened type are reserved by bottom land in the side; Built-in reservoir material can be PPH, can bear certain pressure, is 2/3 of big cell body highly, reserves a purified liquor outlet and is communicated with the junction good seal with the purified liquor outlet of big cell body.This drain pipe is drawn by the bottom from built-in reservoir side, passes outside reservoir, and leaves flange-interface, links to each other all junction good seals with drenching system.This clear liquid inlet pipe connects in the built-in reservoir of insertion by flange from outside reservoir top, links to each other with filtration facility.Muddy liquid goes out pipe and is positioned at outside reservoir side by on the cell body of bottom, links to each other with filtering system.Muddy liquid inlet pipe connects between the built-in reservoir of insertion and the outside reservoir cell body from outside reservoir top by flange, and from then on spray back liquid managed and flowed in the territory, muddy liquid zone.

When many stoves of the Ka Er of precious metal smelting process selenium absorption system is used, operation is all to inject clear water at muddy liquid and clear liquid area, liquid level is lower slightly than the height of built-in reservoir, start muddy hydraulic pressure filter pump, open high-pressure blast and serve as stirring, clear liquid flows into built-in reservoir by filtration facility, and then opens the clear liquid spray pump, and whole water route forms a closed cycle.Owing in a storage tank, move, increase along with the time, the volume of total system remains constant, if the clear liquid return velocity is too fast, to muddy liquid zone, the operation of not influence equipment is if the clear liquid backflow is too late with overflow, the supernatant overflow of muddy liquid zone can guarantee also that to clear liquid area equipment normally moves.The use equipment operation is normal, and the damage phenomenon of pump apparatus did not take place.
