Abstract
The utility model discloses a steel-pipe electrogalvanizing apparatus. In a storage tank (1) with plating solution, a support frame (3) is provided with an anode zinc plate and arranged. A support frame (2) is provided with a steel pipe (5) is arranged. The upper side of the steel pipe (5) is provided with movable anodes (7), and the inside of the steel pipe (5) is placed with a permanent combined anode core (6). The device can improve the quality of galvanized pipes and production efficiency.
Description
The utility model relates to a kind of used device of electroplating, and is specially a kind of device of steel pipe electro-galvanizing.
The device of now used steel pipe electro-galvanizing is in the galvanized coating bath of splendid attire zinc, is equipped with the support of placing steel tubes, and the below of steel pipe is equipped with the support of placing the anode zine plate, and is placed with iron wire or aluminum steel as the anode core in steel pipe.Utilize the electro-galvanizing of this device zinc-plated for the single face anode, lower part sedimentation velocity of the outside surface of the steel pipe in plating bath is fast, and in upper part of outer surface of steel tube, the zinc sedimentation velocity is slow, therefore causes on the outside surface of steel pipe the zinc coating thin and thick irregular; In steel pipe, be placed with iron wire or aluminum steel as the anode core; iron wire electric conductivity low current density is not enough; it is extremely slow to make it on the internal surface of steel pipe the zinc sedimentation velocity; the zinc coating of steel pipe internal-surface is very thin; aluminum steel electric conductivity height; but aluminum steel is serious as the galvanic corrosion of anode core; consumption aluminium amount increases, and has increased cost, and the electroplate liquid in the electroplating process in the pipe is immobilising; zinc ion concentration reduces gradually; though be with iron wire or with aluminum steel as the anode core, can not replenish zine ion, it is very thin to make it the steel pipe zinc coating; and coating usually can appear not having, cause the plating leakage phenomenon.Therefore utilize the device of existing steel pipe electro-galvanizing, the quality of the galvanized steel pipe after the plating is low, and production efficiency is low.
The purpose of this utility model provides a kind of device of steel pipe electro-galvanizing, utilizes the quality height of the galvanized steel pipe after this device is electroplated, and has improved production efficiency.
To achieve these goals, the utility model has been set up movably anode above existing coating bath, and is built-in with permanent combined anode core at galvanized steel pipe.
Below in conjunction with accompanying drawing and with embodiment the utility model is done to be described in detail:
Fig. 1: front view of the present utility model
Fig. 2: A-A is to sectional view among Fig. 1
Fig. 3: the structural representation of permanent combined anode core of the present utility model
Fig. 4: B-B is to sectional view among Fig. 3
The utility model is in the groove 1 of contain electroplate liquid, be equipped with the support 3 that is placed with anode zine plate 4 on it, and be equipped with the support 2 that is placed with steel pipe 5 on it, and in steel pipe 5, be placed with the anode core, also be equipped with movably anode 7 in storage tank 1 above steel pipe 5, the anode core of placing in steel pipe 5 is permanent combined anode core 6.
The movably anode 7 that is equipped with in the top of steel pipe 5 in the said storage tank 1, be to be fixed on the support of rotation, the support of this rotation is to have the upper end to have the upright pole 12 of semicircle supporting plate 11 at storage tank 1 internal fixing, be equipped with rotation axis 9 on the supporting plate 11, be fixedly connected with bracket of right angle type 10 and downward rocker-arm and the support 8 that is connected with external source upwards on the rotation axis 9.Movably anode 7 is fixed on support 8 times, and an end of bracket of right angle type 10 hangs with a balance weight body 13.
Said permanent combined anode core 6 is the bottoms in insoluble pole piece housing 14 grooves, be equipped with the lead 20 that its outside surface scribbles acid and alkali-resistance resin layer 23 and is tied with plastic film 22 and fixes with housing 14, the top of lead 20 is equipped with zink rod 16, the strip conductor 19 that one end of housing 14 is equipped with lead 20 and fixes, scribble acid and alkali-resistance resin layer 18 and be tied with plastic film 17 and be connected with external source on its outside surface as the anode core plug, on housing 14, also be tied with plastic tape sheath 15, should place in steel pipe 5 pipes from two ends by permanent combined anode core 6.
Lead 20 fixes with the fixing also screw of available conduction of housing 14.
As the strip conductor 19 of anode core plug and lead 20 fixedly is rivet 21 fixed with conduction.
Fix as the strip conductor 19 of anode plug and the fixing also screw of available conduction of lead 20.
When utilizing the utility model to carry out the steel pipe electro-galvanizing, place electroplate liquid to make it anode 7 movably on anode 7 movably and be positioned at the top of steel pipe 5 and parallel with steel pipe 5, movably anode 7 has formed last anode, making it steel pipe 5, to be two-sided anode zinc-plated, the sedimentation velocity unanimity of zinc on the outside surface of steel pipe, the zinc coating thin layer is even, if movably anode 7 selects for use zine plate can also constantly replenish zine ion in plating bath, the increase double quick of zine ion the sedimentation velocity of zinc on steel tube surface, help improving the efficient of electro-galvanizing; The permanent combined anode core 6 that two ends in the steel pipe 5 are equipped with, zink rod 16 can constantly replenish zine ion, lead can import steel pipe with big electric current, make and have bigger anodic current density in the steel pipe, can improve the zinc sedimentation velocity of steel pipe inwall greatly, increased the thickness of inside pipe wall zinc layer, the thickness of zinc coating is even and do not have the dead angle, can not cause the plating leakage phenomenon.Therefore the utility model guarantees or has improved the quality of electro-galvanizing steel pipe, enhances productivity.
Electroplate and finish, balance weight body 13 is moved down, rotatable support rotates up, on the swinging strut fixed movably anode 7 break away from storage tanks 1, take out electroplating good galvanized steel pipe, put into steel pipe again, swinging strut is rotated down, and movably anode 7 is the level of state with steel pipe 5.
