Specific embodiment
The present invention is described in detail combined with specific embodiments below.Following embodiment will be helpful to the skill of this field
Art personnel further understand the present invention, but the invention is not limited in any way.It should be pointed out that the common of this field
For technical staff, without departing from the inventive concept of the premise, various modifications and improvements can be made.These are belonged to
Protection scope of the present invention.
Embodiment 1
A kind of for connecting the flexible bridging board 1 of conductive column, structure is as shown in Figs. 1-2, can be closed using copper or copper
The materials such as gold, such as albronze, copper-iron alloy, Sillman bronze make to obtain.Flexible 1 mounted in pairs of bridging board is in conduction
Between column 2 and carbon anode 3, positioned at the two sides of conductive column 2, the top and bottom of flexible bridging board 1 by bolt respectively with conductive column 2
And carbon anode 3 connects, the centre of flexible bridging board 1 is in the semi arch being inwardly recessed, and then conductive column 2 is isolated and connects with carbon anode 3
Touching.The depth for the semi arch being inwardly recessed is the 1/8-1/2 of carbon anode thickness, and imaginary circles for the semi arch being inwardly recessed
The heart is on the outside of bridging board.As shown in Fig. 2, in order to increase deflection, bridging board bending part is U-shaped, rather than semi-circular,
Therefore the center of circle of U-shaped bottom circular arc and the un-flexed part of bridging board are not in the same plane, also should be the virtual of the semi arch
The center of circle is on the outside of bridging board)
Flexible bridging board 1 is combined into elastic connection structure with conductive column, carbon anode.When carbon anode is by external force (boiling fluorine
The lateral force P that bubble generates) when, an angular displacement Δ θ can be generated between conductive column.Fluorine is had since carbon anode is two-sided
Bubble generates, and the quantity of the fluorine gas bubble of two sides generation is asymmetric.So the angular displacement Δ θ generated is with boiling fluorine
Bubble generate lateral force P size and change.Due to varying less for Δ θ, within the elastic deformation of bridging board,
So carbon anode swings by a small margin on conductive column, to eliminate or reduce caused by the moment of flexure generated as external force
Influence of the alternate stress to carbon anode, as shown in Figure 3.
It facts have proved when the thickness (1mm--4mm) of bridging board gets the small value, when the semi-circular arc center of circle is closer to center, Δ θ
Angle becomes larger, and the effect for eliminating flexure stress is more obvious.Conversely, ripple is bent the center of circle far from center when bridge joint plate thickness takes large values
Remoter, Δ θ angle becomes smaller, and eliminates flexure stress decreased effectiveness.Bridging board is more appropriate with a thickness of 1mm--4mm.In the present embodiment
Flexible bridging board with a thickness of 4mm.Electrolysis cylinder working is influenced in order not to keep Δ θ angle excessive, guarantees its minimum interpolar distance
And there are allowances, according to the thickness of climatic conditioning full circle arc radius size and two radius circle center distances and metal plate.
Embodiment 2
It is a kind of for connecting the flexible bridging board 1 of conductive column, structure as shown in figure 4, its structure and embodiment 1 substantially
It is identical, the difference is that, flexible bridging board 1 is advised due to its thickness < 3mm according to electricity in the present embodiment with a thickness of 1mm
Journey needs, and increases auxiliary flexible conducting wire 4, the both ends of auxiliary flexible conducting wire 4 are connected to flexible bridging board top and bottom and lead
Electric column and carbon anode connection connection bolt on so that electric current normal through and bridging board does not overheat.
Comparative example
The applicable cases of existing bridging board 5 as seen in figs. 5-6, using two pieces of parallel copper sheets, with bolt, nut
It is separately fixed on conductive column 2 and carbon anode 3.It is gun iron link, the applied force on bolt between conductive column 2 and carbon anode 3
Size directly affects its contact resistance.In order to reduce contact resistance, often apply large torque (about on bolt, nut
80N meters) or pulled dead.
When electric tank working, a large amount of fluorine gas bubble is generated on anode, electric current is bigger, and bubble is more, fluoride salt boiling
Degree it is more violent, while carbon anode is also bigger by lateral force.Therefore carbon anode is often in the effect of lateral alternate stress
Under, premature fatigue failure (fracture), geosutures 6 mostly concentrate on the bolt fixed part of copper sheet and carbon anode.Carbon anode makes
Most of all only 30 to 60 days with the service life.
Specific embodiments of the present invention are described above.It is to be appreciated that the invention is not limited to above-mentioned
Particular implementation, those skilled in the art can make various deformations or amendments within the scope of the claims, this not shadow
Ring substantive content of the invention.
