Background technology
At present, the used liquid of steel rolling process comprises the purification and the regenerating unit of liquid such as emulsion, alkali lye, coating liquid, generally adopt screen pack, magnetic filter, Huffman filter paper etc. to filter, but effect is relatively poor.Its deficiency:
1, owing to filters that thoroughly not reach filtering accuracy not enough, so, make it in producing use, not reach technological requirement, thereby influence product quality through still having a large amount of impurity in the liquid after filtering;
2, regeneration effect is poor, even goes out of use to using, and causes production cost to strengthen;
3, spare parts consumption is big;
4, bits after filtering fail effectively to handle, and cause environmental pollution.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, provide a kind of effective to used liquid filtering in rolling process, spare parts consumption is low, can not cause the novel steel rolling emulsion purifier of environmental pollution.
Secondly purpose is that backwashing time is short, automatic discharge.
Realize the technical measures of above-mentioned purpose:
Novel steel rolling emulsion purifier, mainly by emulsion fuel tank (1), the coarse filter (2 that is connected with emulsion fuel tank (1), 3), back flushing device (4), sump oil case (5) and oil feed pump (6) are formed, it is to be connected with the film pipe filter (9) that is made of film pipe (8) in turn by pipeline (7) between coarse filter (3) and dreg box (5), purify liquid bath (10), stillpot (11) and self-skimming machine (12), be connected back flushing device (4) by pipeline (7) at film pipe filter (9) with purifying between the liquid bath (10), be separately installed with control valve (15) on the inlet tube (13) of film pipe filter (9) and outlet (14), control valve (15) is connected by the interior PLC programmable device (18) of lead (16) and switch board (17).
It is that film pipe filter (9) has one at least.
When it is film pipe filter (9) for a plurality of installations, the import of each film pipe filter (9) and import, outlet outlet and export between all employing be connected in parallel.
It is that coarse filter (2,3) is connected with stillpot (11) by pipeline (7).
It is to be equipped with scum pipe (19) on self-skimming machine (12).
It is that described control valve (15) is gas/motor-driven valve and magnetic valve.
It is scum pipe (19) branch liquid phase and solid phase scum pipe.
Operation principle
Cleaning principle:
Start oil feed pump, make the PLC programmable device enter duty, open each control valve, emulsion enters coarse filter successively from the emulsion fuel tank impurity the emulsion is tentatively filtered, advance film pipe filter again and carry out fine filtering, after enter the scavenging solution groove.
The backwash principle:
When the relatively poor phenomenon of emulsion filter effect occurring, illustrate that film pipe filter produces obstruction, need carry out backwash.Its program: at first close oil feed pump and each control valve, start back flushing device and control valve, at this moment, the emulsion in the purification liquid bath enters in the film pipe filter from the outlet on the film pipe filter by back flushing device and washes, and enters stillpot again.When the precipitation quantity of slag is big in the stillpot, open the self-skimming machine, precipitation slag respectively enters liquid phase and solid phase scum pipe eliminating with bits by liquid phase and solid phase by the centrifugal action of self-skimming machine, and its liquid phase slag enters stillpot, and the solid phase slag is discharged.
That advantage of the present utility model is is effective to used liquid filtering, backwashing time shortens greatly, spare parts consumption is low, can not cause environmental pollution, production cost is low, compact conformation, and realized automation control.
