Fixed positioned and directional siphon unit
The directed location of the utility model siphon device relates to siphon unit.
In the electroplating technology cleaning method of plating piece have multiple, wherein effective, easy and simple to handle, the cleaning tank concentration of multiple-grooved series connection continuous wash method can be in state of equilibrium, effluent concentration and plating piece clean cleanliness keep constant substantially and be easy to control, water consumption is beneficial to waste water treatment less.Multiple-grooved series connection continuous wash requires quantitative water supply, and cleaning solution is put into the final stage cleaning tank from feed feeder, step by step to the overflow of prime cleaning tank, flows into the waste water treatment chamber by the outlet of first order cleaning tank spill pipe by series sequence at last.In cleaning process, do not allow cleaning solution to produce adverse current, do not reach cleaning performance otherwise can destroy the concentration of lotion balance.Be to adopt nature overflow mode (as dress spill pipe or baffle plate) series connection at present between each groove, therefore can not play control cleaning solution counter flow action.In cleaning tank, add plating piece, clean liquid level and just rise naturally and cause adverse current, poor as if making between each groove the stepped increasing liquid level of liquid level, can prevent adverse current, but cleaning progression for a long time, the liquid level of first cleaning tank certainly will be low excessively, and plating piece all submergence influences cleaning performance.Adopt the method that increases power equipment such as water pump in addition to control adverse current, then will drop into more financial resources and manpower, medium-sized and small enterprises also are difficult to realize.
The purpose of this utility model provides a kind of orientation simple in structure, easy to use location siphon device, needn't increase other power equipments, can effectively control the liquid level of each cleaning tank and keep basic identical, guarantee not produce adverse current, satisfy multiple-grooved and connect the requirement of continuous wash method and reach cleaning performance.
The utility model is achieved in that the siphonal top of u type is zoomed into the air-storage chamber that can store a certain amount of air, avoid u type syphon tube to block siphonage because of producing aeroembolism, relief opening is arranged at the air-storage chamber top, connect a unidirectional venting gas appliance (as sphygmomanometer with suppressing ball) with sebific duct as coupling on the mouth, in order to discharge the air in the air-storage chamber, prevent the air air-storage chamber that bleeds, can in sebific duct, block up a glass marble, the air-storage chamber level is placed on the adjacent two cleaning tank edges, syphon tube inserts respectively in the cleaning solution of adjacent two cleaning tanks, syphon tube overcoat one floating drum in the waterexit end, floating drum outer wall cover one float that floats on the liquid level, but the position up-down adjustment of float on the floating drum wall.
The directed location of the utility model siphon device, it is very convenient that the multiple-grooved series connection is become, as long as each cleaning tank that will connect is arranged in proper order, puts a directed location siphon device on the edge of every adjacent two grooves, promptly forms multiple-grooved series connection continuous wash system.Cleaning solution sucks floating drum earlier by siphonage, overflows into its place groove from floating drum again, and when no special requirement, the result of siphonage, each tank liquor face can keep basic identical (only differing from a float thickness).Because the effect of float, the cleaning solution in the cleaning tank of floating drum place can not flow in the floating drum, have therefore controlled adverse current effectively.
Accompanying drawing 1 is a directed location siphon device structural representation, and 1 is air-storage chamber among the figure; The 2nd, the air-storage chamber relief opening; The 3rd, unidirectional venting gas appliance is unidirectional venting ball (suppressing ball) among the figure; The 4th, sebific duct; The 5th, glass marble; The 6th, syphon tube; The 7th, floating drum; The 8th, float; The 9th, clean liquid level.
Embodiment's schematic representation 2 of the present utility model is 3 grades of multiple-grooved series connection continuous wash flow charts, and 3 directed location siphon devices are arranged, and 10 is quantitative water supply devices among the figure, the 11st, and cleaning tank, the 12nd, overflow pipe outlet, the 13rd, coating bath.Under the siphonage normal condition, cleaning solution is put into the final stage cleaning tank from the quantitative water supply device, cleans the liquid level overflow that constantly raises gradually in the groove, overflows until the overflow pipe outlet from first order cleaning tank at last, and liquid level reaches basic identical in each groove, only differs from a float thickness.In the air-storage chamber of a certain directed location siphon device, airtrapping has too much been blocked siphonage, can gas be discharged by venting gas appliance, present embodiment is to adopt unidirectional venting ball (suppressing ball), as long as pinch the sebific duct at pressure balloon and the glass marble of pinching simultaneously place, make its conducting, air promptly is discharged from the air-storage chamber, and siphonage is recovered.Air-storage chamber is unsuitable excessive, and the work area of cleaning tank is hindered in excessive meeting, and the little exhaust of too small then air storage amount is frequent.Put into plating piece in cleaning tank, this tank liquor face raises, and the float band floating drum and raise together thereupon, has therefore guaranteed to clean in the groove of place liquid level and can not enter floating drum, plays and guarantees not counter flow action.When avoiding exhaust, the floating drum cleaning liquid inside was evacuated before forming siphon, in the floating drum through should be outer through becoming suitable ratio with syphon tube.Utilize the adjustability of float position on floating drum, the liquid level difference between control coating bath and cleaning tank keeps constant automatically.Coating bath liquid level fitness for purpose is lower than cleaning tank liquid level, therefore if with float be displaced downwardly to floating drum in the difference of liquid level to equal the required liquid level of coating bath and cleaning tank poor, when the coating bath liquid level is crossed when low, cleaning solution promptly mends coating bath automatically in the cleaning tank under siphonage, liquid level is identical with the liquid level of cleaning tank in the coating bath floating drum, and the coating bath liquid level promptly reaches the requirement height.For improving using effect, the most handy corrosion-resistant transparent material of syphon tube of the present utility model, be convenient to observe, float is selected for use corrosion-resistant and the material such as the foamed plastics of certain buoyancy is arranged in cleaning solution, and floating drum is slightly less than the resistant material such as the polypropylene material of water with proportion.
