Gate-type working tank of high-speed steel strip continuous nickel plating unit

Abstract

The invention discloses a gate-type working tank of a high-speed steel strip continuous nickel plating unit, the top of the working tank is provided with a conductive roller, the bottom of the working tank is provided with a sink roller, and the cavity of the working tank is internally provided with an anode bridge and an anode assembly; the front side face of a tank body of the working tank is of an opening structure, two doors are connected to the opening of the front side face of the tank body, the tank body is divided into a top square cavity and a bottom conical cavity, the sink roller is installed at the conical cavity, and a liquid outlet and an electroplating liquid inlet pipe assembly are arranged on the front side wall and the rear side wall of the conical cavity. A backflow groove is formed in the upper portion of the top square cavity and connected with an overflow opening, and the overflow opening is formed in the side back to the door. The device is ingenious in conception, nickel adding or replacing operation of the anode assemblies is achieved through the design of the doors on the side faces and the auxiliary trolley, the auxiliary trolley can support the four anode assemblies at a time, the time for replacing or maintaining the anode assemblies every time is greatly shortened, and the working efficiency is greatly improved.

Description

technical field [0001] The invention relates to the field of accessories of a high-speed steel strip continuous nickel-plating unit, in particular to a door-type working tank of a high-speed steel strip continuous nickel-plating unit. Background technique [0002] The continuous battery steel nickel plating line equipment includes an electroplating section. The working tank structure of the electroplating section often adopts a vertical tank structure. Compared with the horizontal tank structure, this structure has faster speed and higher output. The maximum is 30 m / min, but the traditional vertical trough structure is currently used, such as Figure 8 , 9 As shown, the following problems exist during normal production: [0003] 1) It takes a long time to add nickel and change the width specification, which affects the production efficiency. [0004] A sinking roller 5 is installed on the lower part of the tank body 4, and a conductive roller 9 and other devices are instal...

AI Technical Summary

Problems solved by technology

[0003] 1) It takes a long time to add nickel and change width specifications, which affects production efficiency

[0004] The lower part of the tank body 4 is equipped with sinking roller 5, and the upper part of the tank body is equipped with conductive roller 9 and other devices. Due to the fast production line speed and high output, nickel consumption in the anode titanium basket in the working tank is fast, and nickel needs to be added again after 5 days of production. Every time you add nickel blocks, you must stop the machine and remove the conductive roller and other equipment above the working tank, remove the anode bridge and the anode titanium basket screws, and then use the crane to lift out the anode titanium basket. After lifting out, first clean the anode titanium basket and clean the titanium basket. The outer anode bag, then add nickel block to each anode titanium basket, install the anode bag on the titanium basket after filling, and then hoist it to the working tank for installation, and then install the upper conductive roller, the whole unit has a total of 16 electroplating work There are four integral anode components in each tank body, and each anode component filled with nickel weighs more than 400 kilograms. Once nickel is added and installed, it will take 1.5 days to shut down, and the production efficiency is low.

[0005] In the same way, every time the width specification needs to be switched (when the width specification exceeds ±10%, the lower available edge cover adjustment), the anode titanium basket assembly with the same specification as the steel belt 10 must be replaced, and the conductive roller needs to be dismantled each time , remove the anode assembly, the replacement time is longer

[0006] 2) Long maintenance time affects production efficiency

The electroplating working tank must be maintained regularly after a period of normal production. The maintenance items include regular cleaning of scale on the anode bag, regular cleaning of garbage in the working tank, and regular cleaning of the sinking roller. Due to the structural shape of the tank body, cleaning of the anode assembly and disassembly of the sinking roller Maintenance is more troublesome, so each maintenance takes a long time, affecting production efficiency

[0007] 3) The electroplating solution inlet 16 of the conventional working tank is set at the bottom of the tank body, and it needs to be hoisted when connecting with other related parts, which is difficult and inconvenient to operate
