Description
Technical field
The utility model relates to Steel Wire Heat Treatment processing technique fields, more particularly, to a kind of Steel Wire Heat Treatment pickling solution
Automatically switch liquid feed device.
Background technique
Steel wire continuous heat production line is generally used when being heat-treated to steel wire at present, make steel wire 850~
Austenitizing tissue is formed at a temperature of 1050 DEG C, so that steel wire is carried out sorbitizing quenching, and in subsequent pickling, Shui Chong
It washes, water cooling, clean surface scale of steel wire and apply to be covered with specific coatings in favor of following process in the groove bodies such as coating.
Since this production line is continuous production, and 20 or more steel wires are handled simultaneously, highest per hour may be used
Processing 1 ton of steel wire or more, every steel wire is usually 1~2 ton of disk weight, handles the duration generally at 12~36 hours or more,
Therefore the normal table fault-free production of production line is just particularly important: first is that the breakdown maintenance time delays production, second is that because
Steel wire is expansion continuous processing, and intermediate failure causes parking whole depending on the different steel wires that can even make this batch processing of heat treatment
It scraps, loses huge.
The primary focus that the steady and continuous metaplasia of such production line produces has the processes such as heat-treatment furnace, pickling point；It is wherein sour
Process is washed, causes surface scale of steel wire not wash clean clearly if there is failure and directly affects the subsequent steel coated with next step
Silk drawing production, causes drawing process fracture of wire waste product occur.It is usually to improve pickling solution temperature and dense to improve pickling efficiency
Degree, this just gives the acid pump biggish burden of bring for carrying out pickling solution circulation, is also entrained with the oxidation washed down in pickling solution
The impurity such as skin mud, can cause biggish burden to acid pump, and cause is damaged to cause production line scram.
Utility model content
The purpose of the utility model is to provide a kind of automatic switchover liquid feed devices of Steel Wire Heat Treatment pickling solution, solve existing
When pickling solution liquid feed device damages, need completely to shut down the problem of being overhauled, steel wire is caused to scrap.
The technical scheme adopted by the utility model to solve the technical problem is as follows: a kind of Steel Wire Heat Treatment pickling solution is automatic
Switch liquid feed device, including work nest and reservoir, connects the return pipe of work nest and reservoir, the work nest and reservoir
Between be additionally provided with inlet pipe.
The inlet pipe includes the main inlet tube connecting with work nest, first branch's feed liquor connecting respectively with reservoir
Pipe and second branch's inlet tube, one end of the main inlet tube be provided with respectively with first branch's inlet tube and second branch's feed liquor
The threeway of pipe connection is provided with first circulation pump and the first control valve, second branch on first branch inlet tube
It is provided with second circulation pump and the second control valve on inlet tube, is additionally provided with control first circulation pump and second circulation pump opening and closing
PLC controller.
To prevent pickling solution from flowing back into first branch's inlet tube or second branch's inlet tube, first control valve from threeway
It is provided with the first unidirectional stop valve between door and threeway, is provided with the second unidirectional stop valve between second control valve and threeway.
Preferably, first control valve and the second control valve are ball valve, first control valve and the second control
Standard-sized sheet, the only closing when the circulating pump in respective branch needs to change maintenance prevent liquid from returning to valve processed under normal circumstances to strengthen
Stream.
For the switching being suitble under different situations, the PLC controller is encoded with can self-timing switch mode, artificial maintenance
The PLC program of switch mode and failure automatic switchover mode.
PLC program mainly controls program, circulating pump switching control program, self-timing, automatic temperature control heating, liquid by button
The part such as position automatic control, indicator light control, manual manual control forms, wherein pump operating cycle state detection processes and hardware
Thinking is the basis of the utility model: matched hardware facility is separately added into normal Liang Ge circulating pump power supply line
One normally closed electromagnetic contactor of three-phase, by allowing the open and-shut mode of PLC cycle detection contactor obtains the operation of circulating pump
State, to realize the switching control of circulating pump.The addition of the electromagnetic contactor, simple and practical, increased costs are few, but realize
The open/close states and PLC of circulating pump to circulating pump control between closed loop detect control, be that two-shipper is mutually standby, self-timing is artificial
The base controlled system of failover.
The utility model has the beneficial effects that the utility model passes through setting Liang Ge branch inlet tube, and pass through PLC controller
First branch's inlet tube and the work of second branch's inlet tube are automatically controlled, to guarantee in steel wire pickling, when one of them point
When circulating pump on branch inlet tube breaks down, the circulation pump work on another branch's inlet tube can be automatically switched to,
To provide pickling solution for work nest is uninterrupted, guarantee the continuity of Production for Steel Wire, to guarantee the matter of steel wire processing
Amount.The utility model in such a way that a main inlet tube is connect with Liang Ge branch inlet tube, without using two sets it is independent into
Liquid pipe structure is can not effectively to close idle pipeline when because two sets of independent inlet tube structures switching mutually to will cause liquid
Body reflux, addition solenoid valve can improve cost and movement cooperation cannot realize free switching without causing accurately and timely very much
The cutout of circulating liquid.It actually used, observed, or even sudden shut off just running circulating pump artificially to force to be followed
The switching of ring pump, it is seen that normal level of liquid has vibration but declines situation without apparent liquid level in slot, ensure that steel wire pickling quality.
Below with reference to drawings and examples, the utility model is described in detail.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Specific embodiment
Embodiment, as shown in Figure 1, a kind of automatic switchover liquid feed device of Steel Wire Heat Treatment pickling solution, including 1 He of work nest
