Description
Technical field
The present invention relates to a kind of alumina producer decomposer control panel, particularly relate to a kind of electric cabinet that is used for alumina producer decomposer stirring motor distribution and control.
Background technology
Aluminum oxide production process is made up of various physics and chemical process, and its production procedure is long, belongs to continuous flow procedure.Decomposer is very important equipment on the alumina producing flow process, and it imports next production procedure after by the groove mixer slip being stirred.If quit work, will cause whole factory ordinary production to be subjected to significant impact even stopping production comprehensively because of the stirring motor fault.Slip solidifies in the groove in order to avoid simultaneously, also must drain on the spot.Have a strong impact near environmental sanitation.
The decomposer electricity consumption belongs to a stage load.Owing in mechanical structure and the manufacturing, in the decomposer standby stirring motor can not be installed.So can only on control of groove mixer distribution and monitoring technique, try every possible means.
At present the method that adopts usually of alumina producer is on each decomposer top one platform trough stirring motor electrical control cubicles to be installed, and introduces from the different power supply buses sections or two electric power loops of different electrical power (promptly standby each other) power supply.Can automatically switch to during the normal power supply power failure on the stand-by power supply of another one loop, and then the trouble shooting loop.With relevant distribution and controlling parts on two electric power loops of an electric cabinet installation decomposer, not only the electronic-control box profile is big, the sealing difficulty.After the components and parts fault, because can not the interruption of power supply power supply, the maintainer faces the danger of hotline maintenance.Not only maintainer's safety is on the hazard, and under the specified conditions, even can cause the power supply of operate as normal also to be affected, and enlarges incident surface.
Summary of the invention
The technical problem to be solved in the present invention is: a kind of decomposer uninterrupted power supply electric cabinet is provided, can effectively reduces groove electrical control cubicles failure rate, even after the fault, also hotline maintenance is not powered continuously for the groove stirring motor and have been created advantage.
Technical scheme of the present invention is: when design decomposer distribution and control system, components and parts standby, independently distribution and control system each other are divided into two installation units, and assembled with two electric cabinets, mounting arrangements side by side.Because function is clear, independence, be independent of each other, when normal maintenance or trouble hunting, the maintainer disconnects the rear and front end mains switch that needs the maintenance unit, can not charged safety inspection or replace the fault components and parts. and can prepare several tested emergent electric cabinets more.In case find to have fault or fault omen, switch to standby electric cabinet earlier, remove the fault electric cabinet that needs transposing, change with tested electric cabinet, reexamine the electric cabinet failure cause of being changed after a while, after the maintenance debugging finishes, can make the reserve tank of other electric cabinet again, so just can solve fault or maintenance issue fast, guarantee the safe and reliable operation of groove stirring motor electric-control system.
Advantage of the present invention is as follows:
1. simple in structure, replacing convenience, result of use is good.Because with two electric cabinets standby each other and components and parts of ECU (Electrical Control Unit) independently of 2 of mounting arrangements respectively.Electric cabinet overall dimension is less relatively, replaces conveniently.Have fault maybe to need maintenance in case find electric cabinet, integral body is removed electric cabinet earlier, changes with emergent electric cabinet to get final product.Being equivalent to a platform trough mixer has fully independently many electric cabinets do standby for its distribution control.
2. maintenance and easy to maintenance, safety.Because 2 electric cabinet functions are independent, maintenance or safeguard that wherein 1 electric cabinet does not influence the electric cabinet work of other 1 operate as normal fully.
3. easy for installation.After the fabrication and installation of bottom tub steel bracket are finished, with bolt with 2 electric control boxes side by side assembly unit get final product.
Because the above characteristics of this electric cabinet are just progressively promoted in engineering design at present and are adopted.

Fig. 2 is a front view of the present invention;
Fig. 3 is an end view of the present invention.
Embodiment
Embodiments of the invention: press earlier design drawing, power distribution control system is divided into independently first power circuit 1 and second source circuit 2, then with the components and parts of first power circuit 1 and second source circuit 2 respectively mounting arrangements independently control in the chest at 2, be about to that first power circuit 1 and first control unit 3 are installed in first electronic-control box 6, second source circuit 2 and second control unit 4 be installed in second electronic-control box 7; First electronic-control box 6 and second electronic-control box 7 are installed on the channel-section steel support 10, and channel-section steel support 10 is connected with the top of decomposer 9.Rain cover 8 is arranged at the top at first electronic-control box 6 and second electronic-control box 7.
Wherein, the cable between first electronic-control box 6 and second electronic-control box 7 is received casing inner terminal row respectively, uses bolt; In a single day need replace in the use, unclamp bolt and get final product.Ventilating fan and louvre are set in each electric cabinet, and degree of protection is not less than IP54.
During making, the physical dimension of first electronic-control box 6 is a=500mm, b=1600mm, c=600mm.The physical dimension of second electronic-control box 7 is identical with first electronic-control box 6.The height h=300mm of channel-section steel support.
In like manner, also so make needed a plurality of electric cabinets, comprise electronic-control box and power control circuit system as standby.
Be convenient to operation and repair and maintenance place on the decomposer top, press electric cabinet base dimensional requirement with channel-section steel earlier and make the foundation trench steel bracket, with bolt electric cabinet is fixed on the channel-section steel support again.
