Abstract

The utility model relates to a zinc electrobath edge DC bus-bar, comprising a groove-edge bus-bar, a main bus-bar, a vertical current-conducting plate, a groove-edge bus-bar bracket, a bus-bar bracket supporting groove-bar, a cathode groove edge bus-bar conducting strip, etc. The groove-edge bus-bar is a slat conducting copper plate horizontally arranged by the side of the electrobath and supported by the supporting groove-bar and the groove-edge bus-bar bracket, and is connected to the horizontally arranged main bus-bar through the vertical conducting plate led out downward; meanwhile, the main bus-bar is connected to the vertical conducting plate by segments; and after a group of vertical conducting plates are drawn up, the main bus-bar is connected to the next group of vertical conducting plates in a manner that two pieces are reduced in turn; besides, the cathode groove-edge bus-bar conducting strip is overlapped on the groove-edge bus-bar by the small coach bolts arranged in the trench holes of the groove-edge bus-bar bottom by tandem arrangement, and fixed on the groove-edge bus-bar in a permanent manner. Because the electrobath edge bus-bar processed and manufactured by traditional welding is changed into an electrobath edge bas-bar that can be installed in a detachable manner, the reliability of utilization is guaranteed, and the installation and maintenance become easier.

Description

Zinc electrolyte tank limit dc bus device

Technical field

The utility model relates to a kind of zinc electrolyte tank limit dc bus device, belongs to the conduction transmission system that matches with electrolyzer in the electrolytic zinc production technique.

Background technology

Zinc electrolyte tank limit dc bus is that the important shop of electrolyzer helps equipment, and it is made by the fine copper conducting plates.Except be difficult to welding processing greatly because of its current capacity, also exist with vertical conduction plate and cathode collector bar between rationally effectively is connected, unit cross section current capacity and civil engineering structure load-bearing, electric insulation, must be convenient to problems such as installation and maintenance, so be the sector electrical design always with construct in a difficult point.

For many years, domestic traditional design is: splintery trough rim bus is riveted into one group (seeing accompanying drawing), be installed in the groove outside, limit, press with interpole gap welded cathode copper current-conducting piece above, the negative plate current conducting rod is connected with its clamping.There are many defectives in this trough rim bus, and the one, the copper busbar cross section is big, rapid heat dissipation, the welding difficulty is very big; Welding current is too small, and the zone of action can not produce enough heats, does not reach welding requirements, forms rosin joint; Welding current is excessive, can cause that the welding zone is overheated, produces moderate finite deformation, even causes molten copper effusion brazing surface, and metal structure worsens, and welding zone remaining pore etc. reduce the intensity of weld and conducting strip.When going out tankage, easily because of the physical strength collision causes diagonal distortion, even loosening fracture, not only increase the maintenance difficulty, but also directly influence is produced.The 2nd, the high temperature more than 2,000 degrees centigrade that produces during because of welding very easily makes the whole oxidations of contact surface between conducting strip and the trough rim bus generate copper dioxide, and making originally, the conductivity of fine copper descends significantly.Like this, make that junction unit surface current capacity increases between conducting strip and the trough rim bus, cause heating, cause power consumption to increase, technico-economical comparison is descended.

Thereby improve zinc electrolyte tank edges generating line structure, also should be improve electrolytic zinc produce in a useful approach of technical feature and economic target.

Technology contents

The purpose of invention of the present utility model: aim to provide a kind of zinc electrolyte tank limit dc bus device of brand new, the technique for welding of abandoning tradition bus, thereby the reliability that improves the bus conduction and use.

This zinc electrolyte tank limit dc bus device is made up of trough rim bus (2), main bus-bar (6), vertical conduction plate (1), trough rim bus structure (7), cathode can edges generating line conducting strip (3), support channel-section steel (9), it is characterized in that:

A, described trough rim bus (2) are that a monoblock lies against the bar template copper conducting plates of cell body (10) limit portion by a horizontal support channel-section steel (9) and trough rim bus structure (7) support, are linked to each other with the main bus-bar (6) that the lower horizontal direction is provided with by the vertical conduction plate (1) of drawing downwards by it;

B, described cathode can edges generating line conducting strip (3) are stacked and placed on the trough rim bus (2) of bar template, and affixed with trough rim bus (2) by the horizontally-arranged little square head bolt (5) in the following slotted eye (11) of trough rim bus (2) in bottom.

Described trough rim bus (2) is the segmentation connection state with the main bus-bar (6) that the below is provided with, and by after drawing last one group of vertical conduction plate (1), organizes vertical conduction plate (1) with mode and next of two main bus-bars (6) that successively decrease successively and link to each other.

This zinc electrolyte tank limit dc bus device according to above technical scheme design is welded to connect the same device that is combined into the dependence of generally using at present and compares, and has the following advantages:

One,, the more important thing is to help and being connected and carrying out machining of negative electrode conducting strip because the copper conducting plates that lies against cell body limit portion with a monoblock as the trough rim bus, not only is convenient to installation and maintenance;

Two, owing to adopt the trough rim bus to be connected with the segmentation of dividing into main bus-bar, and make main bus-bar successively decrease two in regular turn by the connection in regular turn of follow-up vertical conduction plate, therefore can save 20% left and right sides copper material, simultaneously than traditional way, can also correspondingly reduce civil engineering underwork column load, save construction investment;

Three, owing to the cathode can edges generating line conducting strip that adopts independent cast molding, and adopt bolt to connect, not only make the installation simple and fast; And owing to abandon weldprocedure, accurate pole span, secure contact area have not only been guaranteed; The conducting medium surface oxidation that simultaneously can avoid high-temperature soldering to bring again reduces problems such as specific conductivity.

Embodiment

This zinc electrolyte tank limit dc bus device shown in accompanying drawing 1-5 is transformation and the innovation to traditional slot edges generating line frame mode.At first, it is the plurality of copper bus of will rivet into a group, reform a tabular copper conducting plates that lies against cell body (10) limit portion into, allow it become trough rim bus (2) after the improvement, simultaneously allow this trough rim bus (2) fixedly connected do segmentation again with the main bus-bar of dividing into (6)---promptly after drawing last one group of vertical conduction plate (1), main bus-bar (6) then can successively decrease two successively; And between main bus-bar (6) and trough rim bus (2), form a detachable conductive channel by holding bolt and the vertical conduction plate (1) that is connected both respectively.

Simultaneously, be located at the cathode can edges generating line conducting strip (3) above the bar template trough rim bus (6), also be one by little square head bolt (5) and trough rim bus (2) bolt.

Form a complete bolt electrolyzer installing type direct current groove edges generating line device thus.
