Description

Technical Field

[0001] The utility model relates to the technical field of hot-dip galvanizing reaction tanks, in particular to a hot-dip galvanizing reaction tank without ammonium plating aid. Background Art

[0002] The hot-dip galvanizing reaction tank is mainly used for galvanizing reaction, which coats the surface of metal products such as steel with a layer of zinc to improve its anti-corrosion performance. The hot-dip galvanizing reaction tank is usually composed of multiple parts, including the reaction tank body, heating system, stirring system, control system and auxiliary facilities. In the hot-dip galvanizing process, the steel to be plated is first pretreated to remove impurities such as oil and rust on the surface. Then, the pretreated steel is immersed in zinc liquid heated to a certain temperature, in which an appropriate amount of ammonium-free plating aid is added to the zinc liquid, and then taken out after a certain period of time. In the process of taking the steel out of the zinc liquid, the zinc liquid will form a uniform zinc layer on the surface of the steel, thereby achieving the purpose of anti-corrosion.

[0003] For example, the Chinese patent "A Multifunctional Hot-Dip Galvanizing Agent Reaction Tank" with announcement number CN206599600U includes a main body, a water washing tank, a pickling tank, a plating agent reaction tank and a drying chamber. The main body is fixedly arranged on the top of the base frame, the water washing tank is arranged at one end inside the main body, the pickling tank is arranged at a position inside the main body close to the water washing tank, a plating agent reaction tank is arranged at a position inside the main body close to the pickling tank, a stirring tank is arranged on one side inside the plating agent reaction tank, the stirring tank includes a stirring paddle and a protective cover, the bottom end of the stirring paddle is connected to the output shaft of a rotating motor, a hydrochloric acid tank and an ammonia water tank are respectively arranged at two ends of the other side of the inside of the plating agent reaction tank, the drying chamber is arranged at the other end of the main body, a heating plate is arranged at the bottom end of the drying chamber, a support frame is arranged above the heating plate inside the drying chamber, control valves are arranged at the bottom of the hydrochloric acid tank and the ammonia water tank, the drying chamber is arranged as a thermal insulation material, the protective cover is arranged as a mesh corrosion-resistant material, and rubber pads are fixedly arranged at the four corners of the bottom surface of the base frame.

[0004] Although the above-mentioned prior art can realize the galvanizing operation, in actual use, on the one hand, impurities generated during the galvanizing process are easily left in the galvanizing reaction tank, and metal debris is easy to fall from the metal workpiece during the galvanizing reaction, causing the metal debris to remain in the reaction tank, thereby affecting the galvanizing effect. On the other hand, it is not flexible enough to remove the metal workpiece after the galvanizing process is completed. After the metal workpiece is galvanized, the operator needs to take the metal workpiece out of the galvanizing reaction tank one by one, causing the residual reagents on the metal workpiece to directly contact the operator, thereby increasing the risk of injury to the operator. Therefore, it does not meet the existing needs. In this regard, we propose a hot-dip galvanizing reaction tank without ammonium plating aid. Utility Model Content

[0005] The utility model aims to provide a hot-dip galvanizing reaction pool without ammonium plating aid, so as to solve the problems proposed in the above background technology that impurities generated during the galvanizing process are easily left in the galvanizing reaction pool, and the metal workpiece is not flexible enough to be taken out after the galvanizing process is completed.

[0006] To achieve the above object, the utility model provides the following technical solution: a hot-dip galvanizing reaction pool without ammonium plating agent, comprising an operating table, a reaction pool is fixedly arranged at the middle position of the upper end of the operating table, and support rods are fixedly arranged at the four corners of the lower end of the operating table; and also includes:

[0007] A filter basket is arranged below the reaction tank, and the lower end of the filter basket is a mesh structure, positioning holes are arranged inside both sides of the filter basket, and a fixing rod is arranged inside the positioning hole, and the upper and lower ends of the fixing rod extend to the outside of the filter basket, and the lower end of the fixing rod is clamped and fixed to the filter basket;

[0008] A clamping spring is arranged outside the upper end of the fixing rod, and the clamping spring is clamped and fixed to the filter basket.

[0009] Preferably, second hydraulic telescopic devices are fixedly provided on both sides of the lower end of the operating table, and the telescopic ends of the second hydraulic telescopic devices extend into the interior of the reaction tank and are fixedly connected to the lower end of the fixed rod.

[0010] Preferably, the upper ends of the operating table on both sides of the reaction tank are fixedly provided with first hydraulic telescopic devices, and the upper ends of the telescopic ends of the first hydraulic telescopic devices are fixedly provided with mounting plates.

[0011] Preferably, connecting rods are fixedly provided on both sides of the lower end of the mounting plate, and the lower ends of the connecting rods extend into the interior of the reaction tank, and a placement basket is fixedly provided at the lower ends of the connecting rods located inside the reaction tank.

[0012] Preferably, a motor is fixedly installed inside the operating table, and the output shaft of the motor extends to the inside of the reaction tank.

[0013] Preferably, the motor is located below the filter basket and has fan blades fixedly disposed outside the output shaft.

[0014] Preferably, five heating cavities are arranged inside the side wall of the reaction pool, and the heating cavities are equidistantly distributed, and heating wires are fixedly arranged inside the heating cavities.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] 1. The utility model can recycle metal debris in the reaction tank through the filter basket and the second hydraulic telescopic device. After the galvanizing operation is completed, the placement basket has been removed from the reaction tank and the reagents in the reaction tank are left to stand for a period of time. At this time, the metal debris settles into the filter basket due to its own weight, and then the second hydraulic telescopic device is turned on to extend the telescopic end of the second hydraulic telescopic device. The extension of the telescopic end of the second hydraulic telescopic device drives the filter basket to move upward at a uniform speed until the filter basket is removed from the reaction tank and is located below the placement basket. At this time, the operator removes the retaining spring on the fixed rod, removes the filter basket from the fixed rod, and centrally cleans the metal debris therein to avoid the metal debris from being retained in the reaction tank for a long time, thereby reducing the influence of impurities on the galvanizing operation.

[0017] 2. The utility model can take the metal workpiece out of the reaction tank through the placement basket and the first hydraulic telescopic device. Before the galvanizing operation, the operator places the metal workpiece in the placement basket without contacting each other. At this time, the first hydraulic telescopic device is turned on to shrink the telescopic end of the first hydraulic telescopic device, and the placement basket is driven to move downward by the contraction of the telescopic end of the first hydraulic telescopic device until the placement basket and the metal workpiece are immersed in the reagent. At this time, the galvanizing operation is carried out. When the galvanizing operation is completed, the first hydraulic telescopic device is turned on again to extend the telescopic end of the first hydraulic telescopic device, and the extension of the telescopic end of the first hydraulic telescopic device drives the mounting plate to move upward together with the placement basket until the placement basket is removed from the reaction tank. After a period of time, the reagent on the metal workpiece is drained and then taken out of the placement basket, so that the removal of the metal workpiece is more flexible and the operator is prevented from directly contacting the reagent.

[0018] 3. The utility model can make the reagent generate a vortex in the reaction tank through the motor and the fan blade. When the galvanizing operation is carried out, the metal workpiece is placed in the reaction tank filled with the mixed solution of zinc liquid and the ammonium-free plating assistant. At this time, the motor is turned on to make the output shaft of the motor drive the fan blade to rotate. When the fan blade rotates, the mixture near the fan blade is driven to rotate together. When the mixture rotates with the fan blade, it is subjected to a centrifugal force pointing to the outside of the rotation center. The centrifugal force causes the mixture to gradually diffuse outward during the rotation process and form a vortex during the diffusion process. The vortex formed by the mixture continuously impacts the surface of the metal workpiece, making the galvanizing more uniform, thereby improving the galvanizing effect. The ammonium-free plating assistant helps galvanizing while reducing the emission of ammonia and other harmful gases. BRIEF DESCRIPTION OF THE DRAWINGS

The centrifugal force will cause the mixture to gradually diffuse outward during the rotation process and form a vortex during the diffusion process. The vortex formed by the mixture continuously impacts the surface of the metal workpiece.
