Description
Technical Field
The utility model relates to a PCB manufacture equipment technical field especially relates to a water conservation structure that is used for polish-brush washing and overflow washing technology.
Background
In the manufacturing process of the PCB at present, after electroplating and etching of the PCB, solder resist printing green paint is required to protect a circuit and a copper surface, and the copper surface of the PCB surface is required to be cleaned before solder resist printing, so that a scrubbing and water washing process is required. In the manufacturing process of the PCB, the overflow washing process is also adopted after the grinding and brushing washing process, the two processes are separated to feed water at present, the pollution degree of the sewage after the overflow washing process is low, the sewage is directly discharged after the overflow, so that the water resource is wasted, the environmental protection and the cost saving are not facilitated, and the requirement of the grinding and brushing washing process on the cleanness degree of the fed water is not high actually.
Accordingly, the prior art is deficient and needs improvement.
SUMMERY OF THE UTILITY MODEL
The utility model aims at overcoming the defects of the prior art and providing a water-saving structure for the processes of scrubbing and overflow washing.
The technical scheme of the utility model as follows: the utility model provides a water conservation structure for scrubbing washing and overflow washing technology, include: the overflow washing device comprises an overflow washing tank, a water outlet and a water outlet pipe, wherein the water outlet is communicated with the water outlet pipe, the water outlet is arranged at the highest liquid level of the overflow washing tank, the connecting pipeline is connected with the water outlet and the second water inlet, and the height of the flow dividing port is higher than that of the second water inlet.
Further, the aperture of the shunt opening is 3-7 cm.
Preferably, the aperture of the shunt opening is 5 cm.
Furthermore, a shutoff valve is arranged on the connecting pipeline.
Adopt above-mentioned scheme, the utility model discloses a basin in the aftertreatment technology increases the diffluence pass, and basin in the pretreatment technology increases the water inlet, is communicateing through connecting tube for the sewage of aftertreatment technology continues to use in can introducing the pretreatment technology, is favorable to the water economy resource and saves the cost.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
Detailed Description
The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.
Referring to fig. 1, in this embodiment, the present invention provides a water saving structure for scrubbing and overflow washing processes, including: a grinding brush washing device, an overflow washing device (all not marked) and a connecting pipeline 3, wherein the grinding brush washing device comprises a grinding brush washing tank 2, the scrubbing and rinsing bath 2 is provided with a first water inlet (not shown) and a second water inlet (not shown), the first water inlet is communicated with a water inlet pipe (not shown), the overflow water washing device comprises an overflow water washing tank 1, the rear section of the overflow rinsing bath 1 is provided with a water outlet (not shown) and a flow dividing port 11, the water outlet is communicated with a water outlet pipe (not shown), the diversion port 11 is arranged at the highest liquid level of the overflow water washing tank 1, so that part of used sewage can flow into the diversion port 11, the connecting pipeline 3 connects the diversion port 11 with the second water inlet, and the height of the diversion port 11 is higher than that of the second water inlet, so that water can flow into the second water inlet according to pressure difference. The aperture of the diversion port 11 may be 3-7 cm, in this embodiment 5 cm.
When the utility model discloses the during operation, because the existence of subchannel 11, sewage in the overflow wash bowl 1 has partly can pass through subchannel 11 stays into connecting tube 3, the rethread connecting tube 3 and second water inlet get into polish-brush wash bowl 2, consequently can realize reusing some sewage in the aftertreatment technology, transport to the use in the pretreatment technology, be favorable to water economy resource and cost to 22 hours production calculation of pretreatment technology every day, the prediction can use water wisely about 3 cubic meters in one day.
The utility model discloses still include another embodiment, compare with last embodiment, this embodiment is in connecting tube increases the shutoff valve for can turn-off or adjust as required connecting tube's break-make makes to use more nimble and convenience.
To sum up, the utility model discloses a basin in the aftertreatment technology increases the diffluence pass, and basin in the pretreatment technology increases the water inlet, is communicateing through connecting tube for the sewage of aftertreatment technology continues to use in can introducing the pretreatment technology, is favorable to the water economy resource and saves the cost.
The above description is only exemplary of the present invention and should not be construed as limiting the present invention, and any modifications, equivalents and improvements made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
