Description
Technical field:
The utility model belongs to galvanizing (aluminium) plate surface passivation servicing unit technical field, especially relates to a kind of liquid-adding device for heat zinc coating plate passivation roller coat.
Background technology:
On existing galvanizing or hot-dip aluminizing zinc production line, sheet metal is after galvanizing or aluminum-zinc alloy processing, roller coat passivation process also will be carried out in surface, in roller coat process, passivating solution needs operating personnel by hand it to be pumped in passivation liquid bath in Raw material pail, this has not only increased the weight of staff's burden, and in drawing liquid process, also can cause the unnecessary waste of raw material and bring certain safety in production hidden danger.Only have the concentration of passivation liquid bath is maintained in a comparatively stable scope, its plate surface quality of producing just can be comparatively stable, because its liquid level need to remain on the height of certain limit, but its liquid level is often controlled by operating personnel's experience in actual production process, operating personnel's experience and quality will can affect properties of product and mass formation eventually.In addition, actual production is the technical process of a serialization, in continuous or interruption production process, passivating solution trench bottom can form one deck sedimentary deposit, often need whole charge groove to disassemble cleaning, the steel mill that this produces for serialization, can cause certain economic loss.
Summary of the invention:
The purpose of this utility model is to solve automatic liquid-feeding and liquid bath cleaning problem in galvanizing or hot dip aluminum zinc plate passivation roller coat process, and a kind of liquid-adding device for heat zinc coating plate passivation roller coat is provided.
Liquid-adding device for heat zinc coating plate passivation roller coat provided by the utility model comprises Raw material pail 1, drawing liquid pump 2, motor 3, PLC controller 4, fluid reservoir 6, magnetic valve 7, liquid holding groove 8, the first liquid level sensor 5 and the second liquid level sensor 9, described Raw material pail 1 is positioned at a side of described liquid holding groove 8, described Raw material pail 1, drawing liquid pump 2, fluid reservoir 6, magnetic valve 7 and liquid holding groove 8 are connected successively by catheter, described fluid reservoir 6 is positioned at the top of described liquid holding groove 8, described motor 3 is connected with described drawing liquid pump 2 and described PLC controller 4 respectively by control line, described fluid reservoir 6, in liquid holding groove 8, be respectively equipped with described the first liquid level sensor 5, the second liquid level sensor 9, described the first liquid level sensor 5, the second liquid level sensor 9 is connected with described PLC controller 4 respectively, the described magnetic valve 7 that is positioned at described fluid reservoir 6 liquid outlet places, lower end is connected with described PLC controller 4.
The bottom of described liquid holding groove 8 is provided with pullable draw-in groove 10, at described pullable draw-in groove 10, is provided with sealing ring 11 with the sidewall junction of described liquid holding groove 8, in the bottom of described pullable draw-in groove 10, is provided with blow-off valve 12.
Described pullable draw-in groove 10 is a kind of pullable semilune grooves.Described catheter is polytetrafluoroethylene (PTFE) class conduit, and the material of described liquid holding groove and fluid reservoir is stainless steel.
The utility model is controlled the working condition of motor and the break-make of magnetic valve by PLC controller, liquid level in liquid holding groove is during lower than sensing station, magnetic valve is opened, fluid reservoir is reinforced to liquid holding groove, and motor is started working simultaneously, in raw material suction fluid reservoir, until the liquid level of liquid holding groove reaches liquid level sensor position, motor can automatically be controlled and quit work, and solenoid closure no longer feeds in raw material in liquid holding groove; Otherwise, liquid level in liquid holding groove is during higher than sensing station, solenoid closure no longer feeds in raw material in liquid holding groove, motor quits work no longer to drawing liquid in fluid reservoir, liquid level in fluid reservoir maintains a homeostasis state, liquid holding groove liquid level maintains certain altitude, so forms a cyclic process, keeps passivating solution concentration in liquid bath can not have greatly changed.In addition, the bottom land of this device design is a kind of semilune slidingtype bottom land, in cleaning process, can by bottom land along track pull out avoid whole liquid holding groove to disassemble cleaning, has improved production efficiency.
Accompanying drawing explanation:
Fig. 1 is the utility model structural representation.
Fig. 2 is the structural representation of liquid holding groove in the utility model.
In figure: 1: Raw material pail, 2: drawing liquid pump, 3: motor, 4:PLC controller, 5: the first liquid level sensors, 6: fluid reservoir, 7: magnetic valve, 8: liquid holding groove, 9: the second liquid level sensors, 10: pullable draw-in groove, 11: sealing ring, 12: blow-off valve.
The specific embodiment:
Below in conjunction with accompanying drawing, the utility model is described further.Figure 1 shows that structural representation of the present utility model, the utility model comprises Raw material pail 1, drawing liquid pump 2, motor 3, PLC controller 4, the first liquid level sensor 5, the second liquid level sensor 9, fluid reservoir 6, magnetic valve 7, liquid holding groove 8.Figure 2 shows that the structural representation of liquid holding groove in the utility model, comprise pullable draw-in groove 10, sealing ring 11, blow-off valve 12.
In use procedure, the second liquid level sensor 9 in liquid holding groove spreads out of an instruction to PLC controller 4, motor 3 is started working, drawing liquid pump 2 is pumped into fluid reservoir 6 by raw material in bucket, when liquid storage tank level arrives setting value, the first liquid level sensor 5 spreads out of a signal of telecommunication, now motor quits work, magnetic valve 7 is opened, raw material adds in liquid holding groove 8 automatically, when the position of material liquid surpasses in liquid holding groove the second liquid level sensor 9, magnetic valve 7 closures, the break-make of magnetic valve 7 is controlled by PLC controller 4, so form a circulation, all the time make the liquid level in liquid holding groove remain on a setting liquid level, can make the passivating solution in liquid bath maintain a comparatively stable state.The bottom land of liquid holding groove be one with the pullable draw-in groove 10 of blow-off valve 12, pullable draw-in groove 10 be made to semilune structure be easy to dismounting, in cleaning process, save cost.
