Abstract
The invention discloses a submerged arc furnace short-net copper pipe current converging clamp, and belongs to submerged arc furnace electrode electric conduction components. The submerged arc furnace short-net copper pipe current converging clamp comprises a left clamp plate, a right clamp plate and side steel plates, wherein the left clamp plate and the right clamp plate are mutually butted, and the side steel plates cover the side face of the left clamp plate and the side face of the right clamp plate in a sticking mode. A plurality of arc notches are correspondingly formed in the butted surface of the left clamp plate and the butted surface of the right clamp plate at intervals. The diameter of each arc notch is equal to the diameter of a short-net copper pipe. A plurality of bolt holes are correspondingly formed in the side face of the left clamp plate and the side face of the right clamp plate, the bolts penetrate through the corresponding bolt holes of the left clamp plate and the bolt holes of the right clamp plate, two ends of the bolts are locked through nuts, the left clamp plate and the right clamp plate are made of T2 copper, an insulating plate is additionally arranged between the left clamp plate and the corresponding side steel plate, an insulating plate is additionally arranged between the right clamp plate and the corresponding side steel plate, insulating tube sleeves are additionally arranged in the bolt holes, and insulating gaskets are additionally arranged at the positions where the two ends of the bolts are locked through the nuts. The arc-striking phenomenon of copper content elements ( or electric conduction elements) caused by strong and weak currents is avoided, uneven electrode calcination caused by the uneven current passing through the copper content elements ( or the electric conduction elements) is avoided, and normal and safe operation of the device is guaranteed.
Description
Technical field
The invention belongs to the electrodes in mine hot stove conductive mechanism, belong to the hot furnace apparatus manufacturing in ore deposit, relate in particular to a kind of insulation anchor clamps.
Background technology
At present, the hot stove in the existing ore deposit of China is that combined holder structure or brasses structure all are: transformer---short_net copper pipe---cable---copper pipe---brasses (or conducting element)---electrode in the stove, so basic connection conduction mode.Transformer is divided into two kinds of three-phase transformer and single-phase transformers, again because the short connection transformer outlet terminal of netting often needs short net to jump processing mutually to electrode, add the project organization difference of every stove, caused the transformer outlet terminal inconsistent to the contact tube length of brasses (or conducting element), the electric current that each brasses (or conducting element) is assigned on the electrode just can be not consistent so, has power.Make brasses (or conducting element) take place to beat arc easily, electrode baking is inhomogeneous, damage equipment.
Have again, the problem that we often run in the hot stove combined holder structure Design of ore deposit, for example individual event transformer outlet terminal is 16, and the conducting element quantity of a phase electrode has only 14 groups, and transformer outlet terminal quantity is can't become 14 that fix, Gu need to adopt new insulation jig Design, make 16 outlet terminals of transformer connect the short_net copper pipe outlet after, still can remedy the quantity that copper pipe (or ring pipe) lacks in the stove.
Summary of the invention
The present invention is directed to the deficiencies in the prior art, provide a kind of effective solution CURRENT DISTRIBUTION inequality to cause equipment unit to damage the hot stove short_net copper pipe in ore deposit that problem, the equipment that ensured normally moved, improved the rate of starting of equipment, reduced maintenance and the changed parts anchor clamps that conflux.
Key problem in technology of the present invention is the copper clamping plate that conflux that the cleat insulator with the insulation anchor clamps of prior art conducts electricity instead; and in the bolt hole of clamping plate, set up insulating sleeve; the cushioning insulating washer separates insulation with itself and clamping plate at the nut place, has not only prevented the generation of eddy current but also has played the safeguard protection of insulation.Concrete technical scheme is: the hot stove short_net copper pipe in a kind of ore deposit anchor clamps that conflux, comprise the left and right sides clamping plate of mutual butt joint and the side steel plate that is covered on clamping plate side, the left and right sides, left and right sides clamping plate interface all interval correspondence offers several arc gaps, described arc gap diameter equals the short_net copper pipe diameter, all corresponding spaced apart several bolts hole that is provided with in clamping plate side, the described left and right sides, bolt passes in the bolt hole of left and right sides clamping plate correspondence, two ends nut check, it is characterized in that described left and right sides clamping plate material is T2 copper, set up an insulation board between left and right sides clamping plate and side steel plate, have additional insulative in the described bolt hole, described bolt two ends nut check place has additional insulating washer.Clamping plate butt joint back, described left and right sides arc gap is formed incomplete circle.
Beneficial effect of the present invention: the present invention passes through technique scheme, effectively avoid arc occurring beating because the strong and weak electricity conductance causes brasses (or conducting element), avoided the even electrode baking that produces of the current unevenness that passes through on every block of brasses (or conducting element) inhomogeneous, the operation that assurance equipment is normal and safe.

Embodiment
The hot stove short_net copper pipe in a kind of ore deposit anchor clamps that conflux, comprise the left and right sides clamping plate (001,002) of mutual butt joint and the side steel plate 003 that is covered on left and right sides clamping plate (001,002) side, left and right sides clamping plate (001,002) interface all interval correspondence offers several arc gaps 004, and described left and right sides clamping plate (001,002) butt joint back arc gap 004 is formed incomplete circle.Described arc gap 004 diameter equals the short_net copper pipe diameter, all corresponding spaced apart several bolts hole 005 that is provided with in described left and right sides clamping plate (001,002) side, stainless steel bolt 006 passes in the corresponding bolt hole 005 of left and right sides clamping plate (001,002), lock with nut 007 at two ends, described left and right sides clamping plate (001,002) material is T2 copper, left and right sides clamping plate (001,002) and 003 of side steel plate are set up an insulation board 008, have additional insulative 009 in the described bolt hole 005,006 liang of end nut 007 locking place of described bolt has additional insulating washer 010.
Concrete manufacture method is: according to the termination size of short_net copper pipe in the stove (or ring pipe), determine the conflux length size of anchor clamps of the present invention, customization copper clamping plate (001,002) (dividing left and right two), 9 cross-drilled holes of subdrilling, need the external diameter greater than stainless steel bolt 006, stainless steel bolt 006 is M16mm, and cross-drilled hole is of a size of Φ 25mm, at stainless steel bolt 006 peripheral customization insulative 009(HP-5) Φ 17 * Φ 24mm.Two bronze medal clamping plate need stay the 10mm gap between (001,002), in order to can clamp short_net copper pipe, so need during 8 macropores between two bronze medal clamping plate (001,002) pad to go up the 10mm cushion block in processing, adopt thick boring and hole that the technology of right boring is produced corresponding quantity and size then.In addition, at the insulation board 008(HP-5 of two bronze medal clamping plate (001,002) outside customization with side steel plate 003 same size) so that the side steel plate in copper clamping plate (001,002) two outsides 003 is isolated with copper clamping plate (001,002), guarantee insulation.Add insulating washer 010 respectively at stainless steel bolt 006 two ends, play insulation and separated magnetic effect.Assemble then and installation and interior copper pipe (or ring pipe) end of stove, adopt reasonable method to add and be fixed in the carrying cylinder outside.
