Background technique

In aluminium ring pull end production field, in the cup stamping of pop can molding procedure and stretching process, in forming process It is middle to adhere to oil used in punch forming process and the spot in contamination on tank body, in order to wash such stubbornness Spot is all to carry out high pressure cleaning showers, used cleaning solution by highly acid cleaning solution in the initial stage of cleaning process Generally comprise sulfuric acid and hydrofluoric acid.So big good greasy dirt and acid solution are retained in remaining liq after the completion of cleaning, it is existing Processing mode is usually directly to haul the Liquid Residue to special sewage treatment plant as sewage to handle, and increases enterprise Quantity of wastewater effluent and sewage treatment expense, while acid solution is not reused, and the consumption of acid solution is increased, same to improve Water resource consumed by cleaning and sour usage amount, further increase whole cleaning cost.

Utility model content

One of the purpose of this utility model, which is to provide, can be effectively reduced sewage discharge, reuse the acid solution in sewage Carry out the pop can washing machine waste water reclaiming device of wash cycles.

The device includes a settling tank, and spill box connects the overflow water that input is generated by pickler in oriented spill box Overflow pipe, the top of settling tank is equipped with the oil outlet for exporting upper layer greasy dirt after overflow water stratification, connects outside oil outlet Oil pipe is picked out, settling tank outer lower portion is equipped with after overflow water stratification to the return line of pickler recycling pickling solution； The output end of flowline is connected at the dirty oil tank by settling tank, and the waste oil output for the waste oil that output is collected is equipped on the outside of dirty oil tank Pipeline.

Preferably, overflow pipe region is located in the settling tank and is equipped with overflow buffer area, overflow buffer area passes through Remaining space separates in partition and spill box, and the top edge of partition is located in spill box.

Preferably, the partition is to be obliquely installed structure outward.

Preferably, the flowline is flexible conduit, passes through pendant hanging and spill box in the middle part of the flowline Outer wall.

Preferably, the return line includes return pipe and reflux pump and flowmeter on return pipe.

Preferably, the waste oil output pipe includes waste oil tube and the waste oil pump on waste oil tube.

Preferably, the settling tank is also connected with airlift pump.

The sewage of pickling machine pickling section is input to settling tank by the pop can washing machine waste water reclaiming device of the utility model In staticly settled, so that the greasy dirt in sewage is floated, overflowed by oil outlet, remaining acid solution by return pipe recycling be input to The pickling section of pickling machine uses, and reprocesses after heavy oil dirt centralized collection in treatment process, reduces total sewage quantity；Secondly, pickling The partially recycled utilization of liquid mitigates the content of fluorine ion and sulfate ion in sewage treatment, the difficulty of sewage treatment is greatly lowered Degree.

Detailed description of the invention

Fig. 1 is the modular structure schematic diagram of the utility model embodiment；

Fig. 2 is the positive structure schematic of the utility model embodiment；

Fig. 3 is the overlooking structure diagram of the utility model embodiment.

Specific embodiment

As shown in Figure 1-Figure 3, the pop can washing machine waste water reclaiming device of the present embodiment includes a settling tank 1, overflow Case 1 connects the overflow pipe 2 for the overflow water that input is generated by pickler in oriented spill box 1, and the top of settling tank 1, which is equipped with, is overflowing The oil outlet 3 of upper layer greasy dirt, 3 external connection flowline 4 of oil outlet are exported after flowing water stratification, 1 outer lower portion of settling tank is set Have after overflow water stratification to the return line 5 of pickler recycling pickling solution；It is heavy that the output end of flowline 4 is connected at Dirty oil tank 6 by the case of shallow lake is equipped with the waste oil output pipe 7 for the waste oil that output is collected on the outside of dirty oil tank 6.

When work, the pickling solution of pop can washing machine must keep a certain range of pH value and pollution level, dirty when measuring When the RF value of dirty value reaches the upper limit of setting, can washing machine is automatically added water, and is allowed and is swum in the pollutants such as greasy dirt above cylinder from overflow Mouth flows away, and enters in spill box 1 through overflow pipe 2, is to staticly settle 20 points of time needs in terms of 2 tons by settling tank volume through testing Clock or so, sump oil and acid solution separation layering, it is notable that staticly settle the time and related with spillway discharge, specific separation point The layer exquisite time can comprehensively consider.After sump oil and acid solution separation layering, sump oil has the discharge of oil outlet 3 to reach the collection of dirty oil tank 6 Middle output processing, separating obtained acid solution is recovered to can washing machine use by return line again, to reduce the fluorine in acid solution Ion and sulfate ion decrease the magnitude of recruitment of new acid solution.

In order to reduce influence of the input to standing of can washing machine overflow water, in the present embodiment, it is located in the settling tank 1 Overflow pipe region is equipped with overflow buffer area 101, and overflow buffer area 101 passes through remaining space point in partition 102 and spill box 1 Every the top edge of partition 102 is located in spill box.The water flow of partition overflow pipe output later is set in overflow buffer area 101 Remaining space in spill box 1 is being overflowed to after filling, the influence of the standing effect outside the pressure of water flow is greatly reduced.

Meanwhile in order to make overflow buffer area 101 sluggish flow spilling, further decrease water flow impact pressure, this implementation In example, the partition 101 is to be obliquely installed structure outward.

In the present embodiment, the flowline 4 is flexible conduit, in the middle part of the flowline 4 by a pendant 8 hanging with 1 outer wall of spill box.

In order to control the supply of reflux acid solution, in the present embodiment, the return line 5 includes return pipe 51 and is set to Reflux pump 52 and flowmeter 53 on return pipe 51.

In order to control waste oil output quantity, in the present embodiment, the waste oil output pipe 7 includes waste oil tube and is set to waste oil Waste oil pump 72 on pipe 71.

In the dirty processing of weight, in order to reinforce sump oil separating effect, fine gas bubbles auxiliary can be used and separate, in the present embodiment, The settling tank 1 is also connected with airlift pump (optinal plan is not shown in the figure).

The above is only the preferred embodiment of the present invention, and therefore it does not limit the scope of the patent of the utility model, Equivalent structure or equivalent flow shift made by using the description of the utility model and the drawings, is directly or indirectly transported Used in other related technical areas, it is also included in the patent protection scope of the utility model.
