Description
Technical field
The present invention relates to a kind of wiring construction and mode of connection of Controlling System, relate in particular to a kind of wiring construction and mode of connection of aluminium cell computer control system.
Background technology
Be that action by slot control machine timing control constant-volume blanking device and crust breaking cylinder realizes the electrolyzer alumina concentration is controlled in the process of Aluminium Electrolysis.Be that the control signal of unidirectional reception slot control machine is carried out crust breaking and blanking action to the control of constant volume and unloading device and crust breaker in the past, and do not carry out the answering of shaking hands that feedback signal passes to slot control machine.Normally in not, have only by the time that alumina concentration descends as for the action of crust breaking and blanking device, electrolyzer just can be found after producing anode effect, carry out manual intervention thereupon.Along with the develop rapidly of improvement of computer science and aluminium industry, adopt high production capacity, high-level efficiency, reduce investment outlay, save the energy, the large capacity spot type blanking prebaked-anode type cell of Computerized intelligent control is its inexorable trend.In the large-sized prebaked electrolyzer of SY350～SY400 of new generation, replace half artificialization with intellectuality, in the electrolyzer controlling machine in the position feed back signal introducing electrolysis computer control system of crust breaking cylinder and constant-volume blanking device cylinder, be called for short slot control machine, like this after slot control machine receives the feedback signal of each equipment measuring point of groove top, both can detect the working order of each equipment of groove top, whether equipment is intact, and control the action of each equipment by the slot control machine program, as crust breaking, blanking or the like, form a close loop control circuit.Continuous progress along with cell technologies, corresponding and what come is to have increased constant-volume blanking device cylinder, crust breaking cylinder on every electrolyzer, go out measuring points such as aluminium cylinder and bin full feedback signal, increase by 16 measuring points at most, average each measuring point needs tens meters cables, and the number of cables that whole electrolytic series need increase is considerable.Because used cable is whole from measuring point on the electrolyzer to slot control machine,,, the whole handling of groove superstructure could be gone out output zone so when electrolyzer overhauls, need with after the dismounting of groove upper cable without any breakpoint.Because the cable after removing is difficult to realize utilizing again, so both increased workman's repair time, enlarged construction investment again, caused very big man power and material's waste.
Summary of the invention
For addressing the above problem wiring construction and the mode of connection thereof that the invention provides a kind of aluminum electrolysis control system, purpose is not only to reduce investment outlay but also simple, when improving the Computer Control System of Aluminium Electrolysis function, will greatly reduce engineering cost.
The wiring construction of aluminum electrolytic cell control system, comprise slot control machine, aluminium cell, between aluminium cell and slot control machine, be provided with termination, be provided with connection terminal end of incoming cables and connection terminal leading-out terminal in the termination, the mark terminal links to each other with two terminals of terminal row head and the tail respectively, each equipment measuring point on the aluminium cell is connected on the connection terminal end of incoming cables by cable respectively, each equipment measuring point on the aluminium cell except that anode promotes motor is connected on the connection terminal end of incoming cables by the aluminium cell upper cable respectively, split conductor cable with uniformity signal is connected on the connection terminal leading-out terminal, and aluminium cell bottom split conductor cable is connected with slot control machine.
The housing of described termination is provided with Wiring connector, is provided with screw on four angles.
Described screw passes pad and spring washer is fixed on the housing of termination.
Described housing is insulating material such as steel plate or glass reinforced plastic.
Described termination is located at every aluminium cell flue end top.
The mode of connection of aluminum electrolytic cell control system, adopt ratio phenolic paper laminate as insulcrete, insulcrete is fixed on the support on the electrolyzer, again termination is fixed on the insulcrete, the connection terminal end of incoming cables of termination is connected by cable respectively with each equipment measuring point on the aluminium cell, and the two core cable that will have uniformity signal merges into split conductor cable and is connected on the connection terminal leading-out terminal corresponding with it, and split conductor cable lays to the connection terminal of slot control machine inside along fiberglass cable bridge rack.
The measured signal of each equipment measuring point on the described aluminium cell be the constant-volume blanking device cylinder feedback signal, crust breaking cylinder feedback signal, go out aluminium cylinder feedback signal, bin full signal, anode and promote limited signal under motor signal, anode effect guard signal, the travel switch upper limit and the travel switch.
The feedback signal of described several constant-volume blanking device cylinders is a uniformity signal; Several crust breaking cylinder feedback signals are uniformity signal with going out the aluminium cylinder feedback signal; The travel switch upper limit, travel switch lower limit and anode effect guard signal are uniformity signal.
Advantageous effect of the present invention: save construction investment, reduce construction costs.In the electrolytic aluminium plant of going into operation in the recent period and designing, every upper part of the electrolytic cell has anode to promote about 20 equipment measuring points such as motor need to be controlled by slot control machine.If slot control machine is installed in the potroom aluminium inlet, adopt than the mode of connection that does not adopt this Controlling System, every electrolytic bath top equipment can be saved cable cost about more than 20%.Greatly reduce construction investment.Convenient maintenance reduces the wasting of resources.When electrolyzer overhauls, after needing earlier the tie cable of each equipment measuring point of groove top and slot control machine to be removed one by one, the whole handling of superstructure could be gone out output zone in the past.So both increase workman's workload, increased the time of maintenance again.The recycling possibility of the cable that disassembles like this is minimum, has caused the significant wastage of material resources.After adopting the mode of connection of electrolyzer Controlling System, when electrolyzer need overhaul,, both the whole handling of superstructure can be gone out output zone earlier with after the cable off-the-line that is connected with slot control machine in the termination of groove top, both shortened the repair time like this, original cable is utilized again.
