Description

Technical Field

[0001] The utility model relates to the field of metal processing, in particular to a metal surface galvanizing device. Background Art

[0002] Galvanizing of metal surfaces is a common anti-corrosion treatment method. It forms a protective layer of zinc on the metal surface to extend its service life and improve corrosion resistance. It is usually used in steel products such as steel pipes, steel plates, steel structures, etc. Commonly used electroplating solutions include cyanide zinc plating, zincate zinc plating, chloride zinc plating, sulfate zinc plating, etc.

[0003] In order to better extend the service life of the metal and improve the corrosion resistance, galvanizing can be performed by electroplating, so a metal surface galvanizing device is needed. For example, the prior art Chinese patent publication number "CN217173843U" discloses a metal surface galvanizing device, including a galvanizing pool, and symmetrically arranged cleaning mechanisms are provided on the left and right sides of the galvanizing pool. The cleaning mechanism includes a fixed seat, a first screw, a first motor, a moving seat, a second screw, a second motor, and a moving block. A bracket is fixed on the moving block, and the bent end of the bracket is folded into the galvanizing pool. The first scraper is fixed at one end of the bracket folded into the galvanizing pool. The horizontal section of the bracket is slidably connected with a movable rod, and a second scraper is fixed under the movable rod. A spring rod is provided between the movable rod and the vertical section of the bracket. The cleaning mechanism of the utility model can clean impurities on the surface of the galvanizing liquid without manual cleaning, which is convenient and safe. During cleaning, the rope hanging the metal can also be avoided.

[0004] Some galvanizing devices are equipped with a pair of scrapers to scrape off the scum on the surface of the galvanizing liquid in the galvanizing pool. However, in actual operation, zincate and sulfate galvanizing liquids will produce some solid impurities after the galvanizing reaction, such as zinc cyanide and zinc chloride. These solid impurities will not only precipitate and adsorb on the inner wall of the galvanizing pool, but also affect the quality of metal galvanizing. Similar galvanizing devices can only clean the scum on the surface of the galvanizing liquid, but cannot clean the solid impurities that have been precipitated or even adsorbed. After a long time, the adverse effects on metal galvanizing will become greater and greater. Utility Model Content

DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] Reference Figure 1-4 A metal surface galvanizing device comprises a galvanizing pool 1, a scraper frame 2 and a cleaning wheel 3. A drain port 11 is provided on one side of the bottom of the galvanizing pool 1, and a sealing plate 12 is hinged at the drain port 11. A fixing seat 4 is fixedly installed on one side of the top of the galvanizing pool 1, and a mounting groove 41 is opened in the fixing seat 4. A scraper frame 2 is provided on the top of the galvanizing pool 1, and the bottom of the scraper frame 2 is located in the galvanizing pool 1 and is provided with a scraper 21 and the cleaning wheel 3. A positive electrode and a negative electrode are provided in the galvanizing pool 1, and both the positive electrode and the negative electrode are connected to an external power supply. After the two are energized, the metal is galvanized using a galvanizing liquid by electrogalvanizing.

[0022] Wherein, a driving assembly 5 is disposed in the mounting groove 41 , and the driving assembly 5 is used for driving the scraper frame 2 to move.

[0023] Specifically, the mounting slot 41 is in a convex shape, and the driving assembly 5 includes a first motor 51 . The first motor 51 is fixedly mounted at one end of the mounting slot 41 , and a wire rod 52 is fixedly mounted at the shaft end of the first motor 51 .

[0024] Furthermore, the screw rod 52 is threadedly connected to a threaded block 53, the threaded block 53 is slidably connected to the mounting groove 41, and the scraper frame 2 is fixedly installed on the top thereof, the bottom surface of the scraper frame 2 is located on both sides of the inner wall of the galvanizing pool 1 and is detachably connected to the scrapers 21, the first motor 51 drives the screw rod 52 to drive the threaded block 53 to move, thereby driving the scraper frame 2 to drive a pair of scrapers 21 to move, so that the solid impurities precipitated and adsorbed on the inner wall of the galvanizing pool 1 can be removed, and a rubber pad is provided on the side of the scraper 21 close to the inner wall of the galvanizing pool 1.

[0025] In more detail, a second motor 54 is fixedly installed at one end of the top of the scraper frame 2, and a plurality of first bevel gears 55 are fixedly installed on the shaft end of the second motor 54 passing through the scraper frame 2. A plurality of round rods 56 are rotatably connected to the other end of the scraper frame 2, and a second bevel gear 57 is fixedly installed at one end of the round rod 56. The first bevel gear 55 meshes and rotates with the second bevel gear 57. When the second motor 54 rotates, it drives the first bevel gear 55 to drive the second bevel gear 57 to rotate. The purpose is to drive the cleaning wheel 3 to rotate through the round rod 56 and cooperate with the first motor 51 to move. Considering that solid impurities are most likely to accumulate and precipitate at the bottom of the galvanizing pool 1, the cleaning wheel 3 can well remove the stubborn impurities at the bottom.

[0026] In general, the cleaning wheel 3 includes a fixed plate 31 and a brush plate 32. The other end of the round rod 56 is fixedly mounted with the fixed plate 31.

The connecting spring 33 is not only used to connect the fixed plate 31 and the brush plate 32 together, but also to provide elastic support for the brush plate 32. Considering that the surface of the galvanizing pool 1 will be uneven if there are more impurities deposited at the bottom, the connecting spring 33 can well solve the problem of poor cleaning effect due to uneven surface.

[0027] Finally, a slag scoop plate 6 is detachably installed between a pair of the scrapers 21, a filter plate 61 is provided at the bottom of the slag scoop plate 6, a protective shell 7 is provided on the top of the scraper frame 2, and the first bevel gear 55 and the second bevel gear 57 are both arranged in the protective shell 7.

The protective shell 7 is used to protect the first bevel gear 55 and the second bevel gear 57, and is also used to protect bystanders from being touched and injured.

[0028] Working method: During operation, the galvanizing liquid is poured into the galvanizing pool 1. The metal to be galvanized can be placed in the galvanizing pool 1 by a lifting device using a hanging rope, etc., and the positive and negative electrodes are energized to electrogalvanize the metal. Then, the first motor 51 drives the screw rod 52 to move the threaded block 53, so as to drive the scraper frame 2 to drive a pair of scrapers 21 to move. The scraper 21 removes the solid impurities precipitated and adsorbed on the inner wall of the galvanizing pool 1, and the second motor 54 needs to be started when the scraper frame 2 moves. When the second motor 54 rotates, it drives the first bevel gear 55 to drive the second bevel gear 57 to rotate, and the cleaning wheel 3 is driven to rotate through the round rod 56 to clean the bottom of the galvanizing pool 1 where solid impurities are most likely to accumulate and precipitate. In addition, the slag plate 6 can also scrape impurities floating on the surface of the galvanizing liquid, and then the galvanizing liquid or the cleaning solution is discharged through the drain port 11.
