Abstract
The utility model relates to the technical field of energy-saving and emission-reducing equipment in a tin immersion process, in particular to a water circulating device in the tin immersion process. The device comprises a plurality of rinsing tanks, wherein the rinsing tanks are communicated in a water flowing direction; and the communication mode is that: a first-stage rinsing tank is provided with an overflow opening which is communicated with a first-stage collecting tank; the first-stage collecting tank is communicated with a second-stage rinsing tank through a pump; water in the first-stage collecting tank is pumped into the second-stage rinsing tank by the pump; the second-stage rinsing tank is provided with an overflow opening which is communicated with a second-stage collecting tank; and the second-stage collecting tank is communicated with a third-stage rinsing tank through a pump. In the utility model, water is recycled by collecting the water of a higher stage, so that at least two thirds of water can be saved and the water source consumption is reduced greatly.
Description
Technical field:
The utility model relates to the energy-saving and emission-reduction equipment technical field in the heavy process of tin, refers in particular to the water circle device in a kind of heavy process of tin.
Background technology:
Heavy process of tin is claimed chemical tin plating process again, its be for help circuit card automatic insertion, Chip Packaging specially designed on copper face with chemical mode deposit tin metal plating.Heavy process of tin is a kind of environmental protection novel process that replaces Pb-Sn alloy layer processing procedure, has been widely used in electronic product (like wiring board, electron device) and surface treatments such as handware, ornamental.
Because heavy process of tin is simple to operate, chemical tin plating liquor stable; The liquid medicine consumption is little, long service life, production cost are low; Surface, processing back is prone to clean, no bad smell; Plurality of advantages such as sedimentary coating crystallization is careful, outward appearance is silvery white, surfacing, weldability height and excellent performance are stable, it is widely used.Its working mechanism is to make the stannous ion generation chemical replacement reaction in the plating bath through the chemical potential that changes cupric ion, its essence is electrochemical reaction.
At present, the element of the heavy process of tin of process need pass through washing, to remove its surperficial impurity.In order to wash fully, adopt multistage washing process at present more, as shown in Figure 1.In the present washing process, generally comprise three grades of washing baths 41,42,43, element is cleaned the back taking-up through three grades of washing baths 41,42,43 respectively get final product.But there is the serious problem of water waste in this three grades of washing baths.For example, after cleaning after a while, need change, so just need water be discharged, and quantity discharged be bigger the water in each washing bath.And contain a large amount of metals and chemical substance in the water of discharging, directly discharging will produce bigger pollution to environment.And because its quantity discharged is bigger, also be difficult to it is handled.
The utility model content:
The utility model technical problem to be solved is exactly the deficiency that exists to water washing device in the present heavy tin production line, and the water circulation use device in a kind of heavy process of tin that significantly reduces water consumption is provided.
For solving the problems of the technologies described above; The utility model has adopted following technical scheme: this device comprises some washing baths, and described washing bath is communicated with according to water (flow) direction, and its mode of communicating is: the one-level washing bath is provided with riser; This riser is communicated with the one-level receiving tank; The one-level receiving tank is communicated with the secondary washing bath through pump, through pump the water in the one-level receiving tank is pumped in the secondary washing bath, and described secondary washing bath is provided with riser; This riser is communicated with the secondary receiving tank, and the secondary receiving tank is communicated with three grades of washing baths through pump.
Furthermore, in the technique scheme, described washing bath is three grades or more than three grades., reality can according to circumstances be provided with when using, to reach best cleaning performance.
After the utility model adopts technique scheme; The water of one-level washing bath gets into the one-level receiving tank through overflow; Pump in the secondary washing bath through the water of pump again the one-level receiving tank, in this manner, continuous water with the upper level washing bath; Be pumped in the washing bath of next stage, until last washing bath.And then the water that last washing bath is discharged reclaims.The utility model recycles through collecting the water of upper level, so just can practice thrift 2/3 water, the consumption at the water source that reduces greatly.
Description of drawings:
Fig. 1 is the water washing device that uses in the prior art;
Fig. 2 is the utility model structural representation.
Embodiment:
Below in conjunction with accompanying drawing this full mold is further described:
The utility model is a kind of water circle device that is used for heavy process of tin.It comprises: three grades of washing baths.Described washing bath is communicated with according to water (flow) direction; Its mode of communicating is: one-level washing bath 1 is provided with riser 11, and this riser 11 is communicated with one-level receiving tank 12, and one-level receiving tank 12 is communicated with secondary washing bath 2 through pump 13; Through pump the water in the one-level receiving tank 12 is pumped in the secondary washing bath 2; Described secondary washing bath 2 is provided with riser 21, and this riser 21 is communicated with secondary receiving tank 22, and secondary receiving tank 22 is communicated with three grades of washing baths 3 through pump 23.
During use; Clear water injects in the one-level washing bath 1, and heavy tin element begins in one-level washing bath 1, to begin to clean, along with the continuous injection of clear water; More than water will flow in the one-level receiving tank 12 through riser 11; Since more than hydromining flow out with the overflow mode, so the interior metal impurities of one-level washing bath 1 directly is deposited in one-level washing bath 1 bottom, can overflow to one-level receiving tank 12 in.Through pump 13 water in the one-level receiving tank 12 is pumped in the secondary washing bath 2, so circulation is in water pumps into three grades of washing baths 3.After the water of three grades of washing baths 3 is discharged, can return again in the one-level washing bath 1 through handling again, recycle once more.Because the utility model recycles through collecting the water of upper level, so just can practice thrift 2/3 water, the consumption at the water source that reduces greatly.
Washing bath has adopted three grades in the foregoing description, according to actual needs, can select level Four or more.
Certainly; The above only is the embodiment of the utility model; Be not to limit the utility model scope, all equivalences of doing according to the described structure of the utility model claim, characteristic and principle change or modify, and all should be included in the utility model claim.
