The invention relates to an electrode device of an electrochemical cleaning salt-bath furnace. The device comprises a square cylinder enclosed by four electrically-conducting square side plates and a square bottom plate, wherein every two adjacent side plates are connected through a plurality of first electrically-conducting blocks that are vertically arranged and spaced with each other, so as to form a gap between every two adjacent side plates, and each side plate is connected with the bottom plate through a plurality of second electrically-conducting blocks that are vertically arranged and spaced with each other, so as to form a gap between each side plate and the bottom plate. A 45-degree chamfer is formed at each corner of the bottom plate and each of the side plates, and the bottom plate and each of the side plates are all steel plates of thickness 12-20 mm. The distance between the two adjacent first electrically-conducting blocks is 200-300 mm, the distance between the two adjacent second electrically-conducting blocks is 200-300 mm, and the first electrically-conducting blocks and the second electrically-conducting blocks are all made of 18*18 mm square steel. The electrode device provided by the invention has the advantages of uniform charge distribution, slow corrosion and long service life, so that the electrochemical cleaning salt-bath furnace has good cleaning effect and high cleaning efficiency.

Description

Electrochemistry cleaning salt bath furnace electrode device

Technical field

The present invention relates to a kind of electrode device, particularly relate to a kind of electrochemistry cleaning salt bath furnace electrode device of casting industry.

Background technology

Electrochemistry cleaning is called " Kolene " abroad to be handled, and is used to clear up the cast iron and the steel casting of the complicated and demanding hydraulic part of internal surface degree of cleaning of inner-cavity structure, gas-turbine housing, crankcase, investment cast, also can be used for the surface treatment of steel.Workpiece except that inner chamber is not had scab and the oxide skin, also can improve about three times after carrying out the electrochemistry cleaning work-ing life of golden cutting knife tool, simultaneously, also can improve the surperficial erosion resistance of workpiece, eliminates internal stress.The key equipment of electrochemistry cleaning is called salt bath furnace, its principle of work is as follows: the workpiece of preheating is placed the non-oxidizable fused salt of the interior fused of salt bath furnace cell body (being also referred to as crucible) together with the workpiece basket, and workpiece basket and the intravital electrode of salt bath furnace groove joined with the two poles of the earth of power supply respectively, connect direct current, at a certain temperature, chemical dissolution effect by cathodic reduction, anodic oxidation and fused salt reacts away the scab of workpiece, the iron in the oxide skin is reduced, surperficial graphite is oxidized removes.Now, electrochemistry cleaning salt bath furnace is provided with the electrode special device usually in addition in cell body, the structure of electrode device be front, rear, left and right, the end totally five block plate continuous weldings form, electrode device has the defective that charge distribution is inhomogeneous, electrode corrosion is fast, electrode life is short, makes that the cleaning effect of electrochemistry cleaning salt bath furnace is relatively poor.

Summary of the invention

Technical problem to be solved by this invention provides a kind of electrochemistry cleaning salt bath furnace electrode device, this device has the advantage that charge distribution is even, electrode corrosion is slow, electrode life is long, makes that the cleaning effect of electrochemistry cleaning salt bath furnace is good, cleaning efficiency is high.

For solving the problems of the technologies described above, the invention provides a kind of electrochemistry cleaning salt bath furnace electrode device, it comprises four square side plate and the square cylinder that square floor surrounds of conduction, two blocks of adjacent side plates are arranged by plurality of vertical and the first conduction contiguous block of space connects, so that leave the gap between two blocks of adjacent side plates, each side plate and base plate all are connected by the some horizontally disposed and second conduction contiguous blocks space, leave the gap between each side plate and base plate.

For can concise description for the purpose of the problem, below electrochemistry cleaning salt bath furnace electrode device of the present invention be all abbreviated as this device.

During use, this device is placed on the inside of the metal cell body (crucible) of filling non-oxidizable fused salt, non-oxidizable fused salt is heated to molten state; The workpiece basket that the workpiece that needs cleaning will be housed is again put into the fused solution of non-oxidizable fused salt, and the two poles of the earth of direct supply link to each other with workpiece basket, this device respectively, connects direct current, and process can be finished the cleaning work to workpiece after 30-60 minute.

Because between the adjacent side plate, between each piece side plate and the base plate, between the adjacent first conduction contiguous block, all gapped between the adjacent second conduction contiguous block, avoided wedge angle to greatest extent, reduced the most advanced and sophisticated phenomenon of gathering of electric charge, make charge distribution good uniformity on this device, effectively accelerated the speed of electrochemical reaction; Simultaneously, make non-oxidizable fused salt reduce, reduced production cost the corrosion of this device.Therefore, this device has the advantage that charge distribution is even, electrode corrosion is slow, electrode life is long, makes that the cleaning effect of electrochemistry cleaning salt bath furnace is good, cleaning efficiency is high.

As the improvement of this device, four jiaos of chamferings that one 45 degree is all arranged of described base plate and each side plate, it is the steel plate of 12-20mm that base plate and each side plate all adopt thickness.Like this, make charge distribution more even.

Described two first adjacent spacings of conducting electricity between the contiguous blocks are 200-300mm, and the spacings between two the second adjacent conduction contiguous blocks are 200-300mm, and the first conduction contiguous block, the second conduction contiguous block all adopt the square steel of 18 * 18mm.
