Abstract
The utility model relates to a device for preventing loosening and breaking of an electrode lead. The device comprises two or more electrode leads, wherein threads are respectively machined on two ends of each electrode lead, the electrode leads are staggered and correspond to each other in the vertical direction, two ends of each electrode lead penetrate through a spacing steel pipe of a small cathode framework and are tightly fixed by nuts, the spacing steel pipe of the small cathode framework is provided with a rotation-preventing groove for preventing the rotation of the nuts and the electrode leads, the nuts are welded on a screw rod on two ends of the electrode leads through a spot welding way so as to prevent the loosening and falling, and the situation that the electrode leads are broken from the root part after an electric dust collector runs for a long time can be avoided.
Description
Technical field
The utility model relates to the electric cleaner technical field, is specifically related to the locking and anti-off device of a kind of polar curve.
Background technology
In converter gas dry method cylindrical shape electric cleaner, flue-gas temperature, exhaust gas volumn, dust contained flue gas concentration etc. change along with the periodicity of converter smelting, and this just has higher requirement to the adaptability of polar curve.Tradition polar curve mounting means is in job shop, to insert the polar curve yi word pattern on the negative electrode small frame; Then welding extremely on framework after the polar curve tensioning; Because of welding dead all polar curves again behind each root polar curve of strainer tensioning simultaneously, so installation process can't guarantee that every polar curve installs and fixes inside, back and leaves certain tensile force; Polar curve becomes flexible distortion easily and discharges tensile force in transportation in addition; Such polar curve connected mode polar curve bending and broken string occur easily after deduster operation a period of time, thereby influence the normal use of electric cleaner, and can bring when it is changed very inconvenient.
Summary of the invention
In order to overcome the shortcoming of above-mentioned prior art; The purpose of the utility model is to provide a kind of polar curve locking and anti-off device; The every polar curve that assurance is installed in the electric cleaner all can obtain tensioning, and tensile force is even, has reduced polar curve distortion and broken string phenomenon; Polar curve is changed convenient, and can locking tensioning when the inner replacing of electric cleaner.
In order to achieve the above object, the technical scheme taked of the utility model is:
Locking and the anti-off device of a kind of polar curve comprises the polar curve 1 more than two, and the two ends of polar curve 1 are processed with screw thread, and corresponding up and down polar curve 1 is staggeredly arranged, and the interval steel pipe 2 of negative electrode small frame is passed at polar curve 1 two ends, and fixes with nut 3 tensionings.
The interval steel pipe 2 of described negative electrode small frame is provided with the anti-rotation groove 4 that prevents that nut 3 and polar curve 1 from rotating.
Described nut 3 adopts spot-welded on the screw rod of the two ends of polar curve 1.
The distance that staggers that described corresponding up and down polar curve 1 is staggeredly arranged is 18-22mm.
After described polar curve 1 is in place, guarantee that polar curve 1 inner tensile force is 40～60N.
The advantage of the utility model: the one, can guarantee that the every polar curve that is installed in the electric cleaner all can obtain tensioning, tensile force is even; The 2nd, reduced polar curve distortion and broken string phenomenon; The 3rd, polar curve is changed convenient, and can locking tensioning when the inner replacing of electric cleaner.
Description of drawings
Accompanying drawing is the structural representation of the utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is done detailed description.
With reference to accompanying drawing, the locking and anti-off device of a kind of polar curve comprises the polar curve 1 more than two, and the two ends of polar curve 1 are processed with screw thread, and corresponding up and down polar curve 1 is staggeredly arranged, and the interval steel pipe 2 of negative electrode small frame is passed at polar curve 1 two ends, and fixes with nut 3 tensionings.
The interval steel pipe 2 of described negative electrode small frame is provided with anti-rotation groove 4, is used to prevent the rotation of nut 3 and polar curve 1.
Described nut 3 adopts spot-welded on the screw rod of the two ends of polar curve 1, with anti-loosening with come loose, and avoid in electric cleaner occurring long afterwards running time polar curve from the root situation that breaks.
The distance that staggers that described corresponding up and down polar curve 1 is staggeredly arranged is 18-22mm.
After described polar curve 1 is in place, guarantee that polar curve 1 inner tensile force is 40～60N.
The operation principle of the utility model is:
