Description

The waste emulsified mixture filtration system

Technical field

The utility model relates to a kind of filtration system, relates in particular to a kind of waste emulsified mixture filtration system.

Background technology

A key factor that influences the cold rolled sheet quality is a ROLLING OIL, also can be called emulsion.The composition of emulsion and cleannes are related to the surface quality and the surperficial oil content of strip, and the annealing process that influences the back.

The structure of waste emulsified mixture filtration system of the prior art comprises water pump group 1a, magnetic roller filter 2a, the dirty case 3a of emulsion, water pump group 4a, Schneider filter 5a and emulsion cleaning box 6a as shown in Figure 1.The inlet of water pump group 1a is by being communicated with in the 7a of pipeline and milling train hydrops hole, the liquid outlet of water pump group 1a is communicated with magnetic roller filter 2a by pipeline, magnetic roller filter 2a is communicated with by the dirty case 3a of pipeline and emulsion, the inlet of water pump group 4a is by being communicated with in the dirty case 3a of pipeline and emulsion, and the liquid outlet of water pump group 4a is communicated with emulsion cleaning box 6a is interior by Schneider filter 5a and pipeline.When using this waste emulsified mixture filtration system, by emulsion main pump 8a(centrifugal pump) the interior emulsion of extraction emulsion cleaning box 6a, supply with the lubricated use of operation roll of mill 9a and backing roll 10a, emulsion after the use flows in the 7a of milling train hydrops hole and forms waste emulsified mixture, waste emulsified mixture is by water pump group 1a(centrifugal pump) suction magnetic roller filter 2a, filter the iron powder and the sump oil that contain in the waste emulsified mixture, waste emulsified mixture after the filtration enters the dirty case 3a of emulsion, to in the waste emulsified mixture suction Schneider filter 5a(Schneider filter among the dirty case 3a of emulsion 20 lattice, 50 μ m filter papers be arranged by water pump group 4a again, can filter simultaneously) in, emulsion after the filtration enters in the emulsion cleaning box 6a, as recycling.

But in actual production, because cotton yarn, foreign material and greasy dirt in the milling train hydrops hole are a lot, cause the waste emulsified mixture that enters in the dirty case of emulsion very dirty, make Schneider filter filter effect very poor, often cause the filter paper in the Schneider filter to stop up, produce in a large number and leak, therefore need often the filter paper in the Schneider filter to be changed, the time of changing the filter paper in the Schneider filter is longer, has seriously influenced production.In order not stop production, have only the ball valve between dirty case of emulsion and the emulsion cleaning box is opened, emulsion directly enters under not having the situation of filtering and participates in the emulsion cleaning box using, the scene sees that the emulsion yellowing that is sprayed onto on the roll is blacking up, the cause that Here it is emulsion does not filter well.

The utility model content

At the prior art above shortcomings, the utility model provides a kind of waste emulsified mixture that makes well to be filtered, and does not also influence the waste emulsified mixture filtration system of production simultaneously.

The waste emulsified mixture filtration system that the utility model provides comprises water pump group I, magnetic roller filter, the dirty case of emulsion, water pump group II, Schneider filter, emulsion cleaning box, filter I and filter II; The inlet of described water pump group I is by being communicated with in pipeline and the milling train hydrops hole, the liquid outlet of water pump group I is communicated with magnetic roller filter by pipeline, described magnetic roller filter is communicated with by the dirty case of pipeline and emulsion, the inlet of described water pump group II is by being communicated with in the dirty case of pipeline and emulsion, and the liquid outlet of water pump group II is communicated with the emulsion cleaning box is interior by Schneider filter and pipeline; Opening of sieve in described filter I and the filter II is 80～120 μ m, install after described filter I and the parallel connection of filter II on left magnetic roller filter and the pipeline that the dirty case of emulsion is communicated with, the inlet front end of described filter I and filter II all is equipped with ball valve.

Further, described filter I and filter II are installed in the dirty case of emulsion.

The beneficial effects of the utility model: set up two cover filters on the utility model left magnetic roller filter and the pipeline that the dirty case of emulsion is communicated with, use a cover, a standby cover, at first cotton yarn and bigger foreign material are filtered out by filter, avoid the filter paper in the Schneider filter to stop up, improved the filter effect of Schneider filter; During filter rinsed, switch simultaneously regularly, both can guarantee the emulsion cleaning, reduced the maintenance frequency of Schneider filter again, reduce maintenance cost, guarantee simultaneously to produce and carry out smoothly by ball valve.

The specific embodiment

Below in conjunction with the drawings and specific embodiments the utility model is done explanation in further detail.

Fig. 2 is the structural representation of waste emulsified mixture filtration system in the utility model, as shown in the figure.The waste emulsified mixture filtration system comprises water pump group I 1, magnetic roller filter 2, the dirty case 3 of emulsion, water pump group II 4, Schneider filter 5, emulsion cleaning box 6, filter I 8 and filter II 9.The inlet of water pump group I 1 is by pipeline and 7 interior connections of milling train hydrops hole, the liquid outlet of water pump group I 1 is communicated with magnetic roller filter 2 by pipeline, magnetic roller filter 2 is communicated with by the dirty case 3 of pipeline and emulsion, the inlet of water pump group II 4 is by being communicated with in the dirty case 3 of pipeline and emulsion, and the liquid outlet of water pump group II 4 is by Schneider filter 5 and pipeline and 6 interior connections of emulsion cleaning box; Opening of sieves in filter I 8 and the filter II 9 are 80～120 μ m, and install on left magnetic roller filters 2 and the pipeline that the dirty case 3 of emulsion is communicated with filter I 8 and filter II 9 backs in parallel, and the inlet front end of filter I 8 and filter II 9 all is equipped with ball valve.
