Brief description of the drawings
Fig. 1 is the structural representation of the utility model embodiment 1.
Specific embodiment
With reference to specific embodiment, the technical solution of the utility model is described in further detail, but not structure
Paired any limitation of the present utility model.
Embodiment 1
As shown in figure 1, a kind of retracting device for reducing ammonia nitrogen discharge capacity in alkaline etching machine waste water, including the erosion with peripheral hardware
Carve the connected sub- liquid washing trough 11 of section 17, also including be sequentially connected the first rinsing bowl 2, for by the liquid drying on pcb board
Hair drying device 3, the second rinsing bowl 4, the 3rd rinsing bowl 5, the first described rinsing bowl 2 are connected with sub- liquid washing trough 1, and described first
Rinsing bowl 2 is also connected with the temporary storage barrel 7 for storing surplus liquid in the first rinsing bowl 2 by the 3rd overflow pipe 6, and described the
Running water water inlet pipe 8 is connected with three rinsing bowls 5, the first overflow is provided between the 3rd described rinsing bowl 5 and the second rinsing bowl 4
Pipe 9, connects the second overflow pipe 10 of oriented first rinsing bowl 2 overflow, the second described rinsing bowl 4 on described hair drying device 3
It is provided with and temporary storage barrel 7 between for the filling pipe 11 to the moisturizing of temporary storage barrel 7, between the described rinsing bowl 2 of temporary storage barrel 7 and first also
Circulation pipe 12 is provided with, drainpipe 13 is also associated with the second described rinsing bowl 4.The end of described drainpipe 13 is connected to useless
Water station 14, described temporary storage barrel 7 is connected to one is used to store the spent etching solution bucket 15 of spent etching solution.
It should be noted that the sub- liquid of etching solution that sub- liquid washing trough 11 is used, for mother liquor, copper ion therein is
Through by a large amount of recovery, content of copper ion is relatively low, and the cleaning by the neutron liquid of sub- liquid washing trough 11 to pcb board can collect pcb board
On copper ion, improve sub- liquid concentration, reach the purpose that can be etched again.
First rinsing bowl 2 with water comes from temporary storage barrel 7, and the liquid in temporary storage barrel 7 comes from the second rinsing bowl 4, typically
In the case of, the strength of fluid from the injection of the second rinsing bowl 4 is relatively low, pcb board can so be washed by circulation pipe 12, water
Wash into the first rinsing bowl 2, when the liquid level in the first rinsing bowl 2 is too high, then temporary storage barrel is entered by the 3rd overflow pipe 6
7。
When strength of fluid is too high in temporary storage barrel 7, carried out simultaneously using two kinds of operations, first by the liquid in temporary storage barrel 7
Drain into spent etching solution bucket 15 to store, and the strength of fluid in temporary storage barrel 7 is reduced to moisturizing in temporary storage barrel 7 by filling pipe 11.
When pcb board needs to blow away the liquid on pcb board by hair drying device 3 by after the washing of the first rinsing bowl 2, blow away
Liquid by the overflow of the second overflow pipe 10 to the first rinsing bowl 2.Specifically, hair drying device 3 includes a cavity for closing,
Connecting fan 16 on cavity, are blown off liquid by blower fan 16, can so improve the washing efficiency of the second rinsing bowl 4.
When pcb board is washed by entering into the second rinsing bowl 4 after hair drying device 3, washed subsequently into the first rinsing bowl 2,
Washing concentration also comes lower, and such pcb board is with regard to wash clean.
Whole equipment simple structure, but cleaning performance is good, and ammonia nitrogen waste water major part can be recycled, and a small amount of can
Effective collection treatment, reduces environmental pressure.
Above-described is only preferred embodiment of the present utility model, all in spirit of the present utility model and spirit
Any modification, equivalent and improvement for being made etc., should be included within protection domain of the present utility model.
