Description of drawings
Fig. 1 is a synoptic diagram of the present utility model;
Fig. 2 is the synoptic diagram of the another kind of embodiment of the utility model.
Embodiment
A kind of single stage method solid epoxy water saving production system as shown in Figure 1, comprise reactor 1 and suction unit 2, suction unit 2 is used for the washes behind the product in the sucking-off washing still, the water outlet of suction unit 2 is provided with bypass pipe, bypass pipe is passed into water tank 3, and the water body in the water tank 3 can be transported in the reactor 1 by water pipe.That is to say that the water outlet at original suction unit 2 has increased bypass pipe, such washes that pumps out can discharge as originally, also can send into water tank 3 through bypass pipe and store stand-by.
Can have multiplely as for the mode that the water bodys in the water tank 3 is transported to reactor 1, modally be exactly: the fluid pump 6 that on the water outlet of water tank 3 and reactor 1 pipeline between directly, is provided for carrying washes.Because with the washes sucking-off, so need not to be provided with fluid pump 6 equipment such as grade on this section pipeline, 6 of fluid pumps mainly are that the materials in the water tank 3 will be sent back in the reactor 1 again as the former water use of washing to suction unit 2 itself again by vacuum tightness.The fluid conveying is quick and convenient like this, and the installation site of equipment is not strict with yet.
Perhaps as shown in Figure 2, the water outlet position of suction unit 2 is higher than the water inlet position of water tank 3, and the water outlet position of water tank 3 is higher than the position of reactor 1 and is communicated with by pipeline with reactor 1 top.Just the installation site of suction unit 2 is the highest, water tank 3 takes second place, reactor 1 is minimum, and washes is discharged the back by suction unit 2 water outlets and flowed into water tank 3 naturally like this, is put in the reactor 1 when needing then again.So just need not fluid pump 6 is set, be beneficial to energy-conservation.
Certainly, it is common practise that valve pilot piping break-make is set on each equipment and the pipeline, need not superfluous words.
Further, best described water tank is provided with a plurality of and is connected with the water outlet of suction unit 2 with bypass pipe respectively.Be provided with two exactly as Fig. 2, the washes after so each washing can be stored in respectively in the different water tank 3,4.So just can utilize respectively, be convenient to control and the concentration difference when improving the recycling washes and washing, improve overall detersive efficiency containing the residue washes different with byproduct concentration.By experience, described water tank preferably is provided with two; Can be convenient to reclaim washes, simultaneously also unreasonable operating device cost.The water outlet of water tank 3,4 is communicated to test tank 5, and the outlet position of test tank 5 is higher than reactor 1 position and is communicated with by pipeline with reactor 1 upper end.That is to say that water tank 3,4 just is provided with two, be respectively applied for the washes of collecting the 1st, 2 time reciprocal and get final product that previous washes can directly be discharged into the sewage disposal operation because concentration is higher.The setting of test tank 5 is for the accurate water consumption of control washing, avoids adding water excess or deficiency, has not only guaranteed washing effect simultaneously but also water saving, also avoids the amount of the former water of washing in personnel's visual inspection still, is convenient to production operation, has also improved processing safety.
