Embodiment
The utility model is described in further detail below in conjunction with specific embodiment and accompanying drawing thereof.
As depicted in figs. 1 and 2, a kind of aluminium cell short-circuit busbar of meeting an urgent need, comprise that water conservancy diversion bus 6 and aluminium are flexible coupling 5, weld with argon arc welding with a be flexible coupling end of 5 of the aluminium that is semicircular arc respectively the top at water conservancy diversion bus 6 two ends, be flexible coupling 5 the other end of aluminium welds with argon arc welding with short-circuit busbar 4 tops respectively, two short-circuit busbars 4 are vertical relation with water conservancy diversion bus 6, and are positioned at the lower position of water conservancy diversion bus 6.The sectional dimension of water conservancy diversion bus 6 and short-circuit busbar 4 is identical with the sectional dimension of anode rod 3, mainly is for the ease of short-circuit busbar 4 is fixedly attached on the positive bar 1 by small box fastener 2.The short-circuit busbar 4 of water conservancy diversion bus 6 one ends is fastened on by small box fastener 2 on the positive bar 1 of accident electrolyzer 11 electricity output sides, and the short-circuit busbar 4 of water conservancy diversion bus 6 the other ends also is fastened on the positive bar of normal electrolyzer 12 electricity input sides in adjacent downstream 1 by small box fastener 2.
The middle part of water conservancy diversion bus 6 is equipped with reinforcing sleeve 7, and reinforcing sleeve 7 comprises the U-shaped steel plate cover with the 6mm Plate Steel of flanging of two die casts up and down.As shown in Figure 3, the flanging of two U-shaped steel plate covers up and down is fixedly connected with bolt.Because the span of the water conservancy diversion bus 4 of cross-slot is larger, water conservancy diversion bus 4 feels like jelly after its deadweight and the energising, the sagging phenomenon of water conservancy diversion bus 4 easily occurs, when reinforcing sleeve 7 can prevent that water conservancy diversion bus 4 is overheated in the middle of the waist phenomenon of collapsing of appearance.
Be separately installed with the steel plate web plate 8 of two symmetries between the two ends of water conservancy diversion bus 6 and two short-circuit busbar 4 tops.Be drilled with respectively the through hole of six Φ 13 at the two ends of water conservancy diversion bus 6, be drilled with Φ 13 through holes in the upper middle position of short-circuit busbar 4; One end of web plate 8 is drilled with the through hole of six Φ 13, and seven M12 threaded studs of 9, two web plates of elliptical aperture, 8 usefulness that the junction on the other end and short-circuit busbar 4 tops is drilled with a R10 * 40mm are fixedly connected with.The external part steel plate length of web plate 8 exceeds short-circuit busbar 4 outside 50mm.In order to guarantee to fix the position of two short-circuit busbars 4, bore up and down the through hole of two Φ 13 at the external part of web plate 8, then connect two web plates 8 with two M12 threaded studs, about form respectively two caging bolts 10, even pass the bolt fracture of elliptical aperture 9, can guarantee that still the position of short-circuit busbar 4 is not offset.Two web plates 8, not only can strengthen aluminium be flexible coupling 5 with being connected that water conservancy diversion bus 6 is connected with short-circuit busbar, and the external part of web plate 8 exceeds the steel plate of short-circuit busbar 4 outside 50mm, is convenient to short-circuit busbar 4 is set up on the positive bar 1, plays the effect of support.Because the positive bar spacing between adjacent two electrolyzers is incomplete same, can be by the position of the elliptical aperture 9 on the web plate 8, adjust the length of emergent short-circuit busbar, the variation of spacing between the positive bar between adaptation accident electrolyzer 11 and the normal electrolyzer 12.
The size of the emergent short-circuit busbar of aluminium cell can be selected according to different pot lines.For example the 400KA electrolyzer can be chosen four electrolyzers and measure respectively the spacing between the positive bar between its two electrolyzers, then calculates mean value L=4830mm; The length of getting cross-slot water conservancy diversion bus 6 is 4170mm, and the length of short-circuit busbar 4 is 700 mm, and being flexible coupling with the aluminium of 15 bundle (10 soft bands of aluminium of every bundle) 200 * 1mm respectively between water conservancy diversion bus 6 and the short-circuit busbar 45 is semi arch and welds with argon arc welding; The sectional area of anode rod 3 is of a size of 200 * 180mm, and then the sectional area size of water conservancy diversion bus 6 and short-circuit busbar 4 is 200 * 180mm.Reinforcing sleeve 7 is that thickness is that 6mm, length are the steel plate of 2000mm, connects with bolt every 200mm; Web plate 8 is steel plates of 680 * 170 * 16mm.
In actual production process, blast when short circuit mouth for electrolytic bath and to cause many root posts bus and short-circuit busbar scaling loss, or when the short-circuit block below soft band of negative electrode or bus occurring and damaging, the emergent short-circuit busbar of the aluminium cell that can use the utility model to provide carries out short circuit.For example, certain three short-circuit openings that electrolyzer occured at the 400KA prebaked cell are blown out phenomenon, cause three short-circuit openings and three root post buses badly damaged, and insulcrete and insulation tube burn out, and series can't be carried out short circuit and stop groove after being had a power failure.In this case, the emergent short-circuit busbar of the aluminium cell that uses the utility model to provide, under the state that series has a power failure, at first rapidly the B face of accident electrolyzer 11 and each 12 groups of anode rod group of A face of adjacent normal electrolyzer 12 are extracted in turn fast with two multifunction cranes, then overlap in the small box fastener 2 of emergent short-circuit busbar insertion accident electrolyzer B face and normal electrolyzer A surface anode bus 1 12 respectively with multifunction crane, and by artificial means with the bolt tightening of small box fastener 2, the short-circuit busbar 4 of guaranteeing emergent short-circuit busbar contacts fully with the electrolysis of positive bar 1, carries out series behind at last inspection accident electrolyzer 11 and the normal electrolyzer 12 short-circuit opening electrolysis and send electricity.Like this, by emergent short-circuit busbar accident electrolyzer 11 and normal electrolyzer 12 are carried out short circuit, get rid of accident electrolyzer 11, can guarantee as early as possible Power resumption of serial electrolyzer.Whole short circuit process, the time is short, easy and simple to handle, and carrying, easy for installation only needs about 1 hour.Compare with the accident temporary short-circuit busbar of prior art, can save 3～4 hours repairing time, guaranteed that whole serial electrolyzer can within the shortest time, recover the series power supply, the normal production that recovers electrolyzer.
Setting up emergent short-circuit busbar to recovering between three short-circuit blocks and riser bus bar normal production period, can directly reflect the current distributions (test chart sees Table 1) that each emergent short-circuit busbar passes through to the temperature of emergent short-circuit busbar and the variation that routine test, particularly temperature have been carried out in pressure drop.By operation in tens days, data presentation was produced normal, can conclude that this emergent short-circuit busbar is reasonable in design, reached the needs that aluminum smelting technology is met an urgent need in the state of accident.
Table 1: the interim equidistant pressure drop of bus and temperature gauge
Above-described only is preferred embodiment of the present utility model, does not limit to the utility model.Should be understood that for the person of ordinary skill of the art, under technology enlightenment provided by the utility model, can also make other equivalent modifications and improvement, all can realize the purpose of this utility model, all should be considered as protection domain of the present utility model.
