Description

Technical Field

[0001] The utility model relates to the technical field of zinc melting, in particular to automatic zinc melting equipment. Background Art

[0002] In the galvanizing process, the use of galvanizing melt is crucial. However, due to the instability of zinc ions, the control of their concentration has become a difficult task. Traditionally, this task has relied entirely on manual operation, which undoubtedly increases the complexity and uncertainty of the galvanizing process.

[0003] In the traditional galvanizing process, the molten zinc tank is usually designed with a single-layer structure. Operators need to regularly analyze the zinc ion concentration to ensure that it is maintained at an appropriate level. When the zinc ion concentration is low, zinc ions need to be replenished in time to prevent the galvanizing effect from being damaged. In this process, a crane is used to place the suspended molten zinc basket into the alkaline plating solution, and then the zinc melting mode is started to melt the zinc block, thereby increasing the concentration of zinc ions in the molten solution.

[0004] However, this method that completely relies on manual operation is not only time-consuming and laborious, but also has many disadvantages. First, when manually analyzing the zinc ion concentration, it is difficult to ensure the accuracy and stability of the analysis due to various factors, such as the operator's experience, skill level, fatigue level, etc. This will cause the zinc ion concentration in the galvanizing melt to fluctuate greatly, which in turn affects the quality of the galvanized product.

[0005] Secondly, manual operation also has certain safety risks. During the operation, the operator needs to be exposed to harmful substances such as alkaline plating solution. If proper protective measures are not taken, it is easy to cause harm to the human body. In addition, frequent driving operations and replacement of zinc melting baskets will also increase the labor intensity and safety risks of operators.

[0006] In the existing process, the molten zinc blue needs to be hung at a high place. Although this can prevent the zinc ion concentration from being too high, there are two major safety hazards. First, the hanging operation itself is dangerous; second, employees often forget to lift it up when leaving get off work, resulting in excessive zinc ion concentration the next day, which has a serious impact on product quality.

[0007] Therefore, based on the above technical problems, it is necessary for technicians in this field to develop an automatic zinc melting equipment. Utility Model Content

[0008] The utility model aims to provide an automatic zinc melting device to solve the common problems raised in the above background technology.

[0010] As a preferred technical solution, a plurality of partition brackets for support are arranged at the bottom of the partition bottom plate, and the plurality of partition brackets are distributed at equal intervals and fixedly connected to the zinc melting tank.

[0011] As a preferred technical solution, the zinc plate in the molten zinc basket can be placed horizontally, vertically or tilted. The molten zinc basket is an iron frame, and the tilted placement has the largest contact area and the best effect.

[0012] As a preferred technical solution, the plug-pulling device is a manual plug-pulling device or an automatic plug-pulling device, wherein the automatic plug-pulling device can be lifted by a cylinder, a screw, an electric cylinder or a worm gear.

[0013] As a preferred technical solution, partitions are symmetrically arranged in the upper zinc molten tank, and overflow lower plates are arranged outside the two partitions.

[0014] As a preferred technical solution, an anti-corrosion lifting pump is arranged outside the zinc melting tank, the input end of the anti-corrosion lifting pump is connected with a suction pipe, the suction pipe is communicated with the lower tank, the output end of the anti-corrosion lifting pump is connected with a discharge pipe, and a zinc ion analysis device is installed on the discharge pipe.

[0015] As a preferred technical solution, the tail end of the discharge pipe is connected to a plating tank, and a zinc ion analysis device is installed in the plating tank.

[0016] As a preferred technical solution, the plug body is arranged in a truncated cone shape and abuts against the flow opening, and is used for opening and closing the flow opening.

[0017] As a preferred technical solution, the partition is used to block floating oil and other suspended matter on the surface of the plating solution to facilitate cleaning.

[0018] Compared with the prior art, the beneficial effects of the utility model are:

[0019] (1) The utility model is an automatic zinc melting device, wherein a partition bottom plate is arranged in the upper zinc melting tank to separate the upper zinc melting tank into independent spaces, each of which is provided with a zinc melting basket, and the zinc plates in the zinc melting basket react with the alkaline plating solution to generate zinc ions. By controlling the number of zinc plates in the zinc melting basket and the zinc melting time, the amount of zinc ions generated can be accurately controlled. After the reaction, the plating solution with a high zinc ion content flows into the partition of the separation tank through the overflow lower plate, wherein the floating oil and other suspended matter on the surface of the plating solution are blocked by the partition and float on the liquid surface, which is convenient for cleaning to keep the plating solution pure.

[0020] (2) The utility model is an automatic zinc melting device, which also has multiple working modes, including automatic zinc melting mode, non-zinc melting mode and manual zinc melting mode, and the corresponding mode can be selected for operation according to actual needs.

When the zinc ion content is lower than the preset value, the opening and closing of the flow port are controlled to realize the zinc melting and non-zinc melting actions, thereby controlling the replenishment of zinc ions and maintaining the zinc ion concentration in the plating solution stable.

[0021] (3) The utility model is an automatic zinc melting equipment, which also has the advantages of simple structure, convenient operation, safety and reliability. By setting up a partition bottom plate and a zinc melting basket, the potential safety hazard brought about by the traditional basket lifting method can be effectively solved.

DETAILED DESCRIPTION

[0028] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0029] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0030] Example

[0031] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the utility model provides a technical solution for automatic zinc melting equipment: including a zinc melting tank 1, a partition bottom plate 13 is installed inside the zinc melting tank 1, and a plurality of evenly distributed partition brackets 12 are arranged below the bottom plate, which are tightly connected to the zinc melting tank 1 to ensure stability. An upper zinc melting tank 14 is arranged above the partition bottom plate 13, and a lower tank 11 is arranged below. In the upper zinc melting tank 14, multiple groups of zinc melting baskets 21 are arranged, and each zinc melting basket 21 is provided with a zinc plate 22. These zinc plates 22 can be placed horizontally, vertically or tilted according to needs. The zinc melting basket 21 is an iron frame, and the tilted placement has the largest contact area and the best effect.

[0032] An alkaline plating solution overflow pipe 3 is arranged on the left side of the zinc molten tank 1, and the pipe is connected to the upper zinc molten tank 14 to realize the smooth flow of liquid. A plug removal device 4 is arranged in the upper zinc molten tank 14, and the device can be operated manually or automatically. Among them, the automatic plug removal method can adopt a mechanism such as cylinder lifting, screw lifting, electric cylinder or worm gear lifting. A plug body 401 is arranged at the bottom of the plug removal device 4.

[0033] A flow port 131 is provided on the partition bottom plate 13 to facilitate smooth exchange of fluid. The plug body 401 is arranged in a truncated cone shape and abuts against the flow port 131, and is used to open and close the flow port 131 to achieve the sealing and opening functions. The upper zinc melting tank 14 is symmetrically provided with a partition 16, which is used to block the floating oil and other suspended matter on the surface of the plating solution for easy cleaning. At the same time, an overflow lower plate 15 is installed on the outside of the two partitions 16 to control the flow direction of the fluid. An anti-corrosion lifting pump 41 is installed on the outside of the zinc melting tank 1. The pump is connected to the lower tank 11 through a suction pipe 42, and the treated liquid is discharged through a discharge pipe 43. The tail end of the discharge pipe 43 is connected to the plating tank, and a zinc ion analysis device is installed in the plating tank for real-time monitoring and analysis of the composition of the fluid.

[0034] Zinc melting mode (zinc ion supplementation mechanism):

[0035] The alkaline plating solution flows into the entrance of the upper zinc melting tank 14 through the alkaline plating solution overflow pipe 3. The automatic plug removal device 4 controls the plug body 401 to press down, and at this time, the flow port 131 of the partition bottom plate 13 in the upper zinc melting tank 14 is closed. The alkaline plating solution flows into the upper zinc melting tank 14, and then contacts the zinc plate 22. The zinc plate 22 and the alkaline plating solution react to melt zinc, increasing the zinc ion concentration. After the reaction, the plating solution with a higher zinc ion content flows into the separation tank partition 16 through the overflow lower plate 15, wherein the floating oil and other suspended matter on the surface of the plating solution are blocked by the partition and float above the liquid surface, which is convenient for cleaning to keep the plating solution pure.

[0036] Subsequently, the plating solution with high zinc ion content flows into the lower tank 11 through the overflow lower plate 15, and is then sucked along the suction pipe 42 by the anti-corrosion lifting pump 41 and sent to the plating tank through the discharge pipe 43, and the cycle is repeated to ensure the continuous replenishment of zinc ions. This process makes the concentration of the plating solution in the plating tank uniform, thereby ensuring that the film thickness of the plated workpiece has excellent consistency.

[0037] Insoluble zinc mode (no zinc ion supplement required):

[0038] The automatic plug removal device 4 controls the plug body 401 to rise, and the flow port 131 of the partition bottom plate 13 in the upper zinc melting tank 14 is opened. All alkaline plating solutions flow directly into the lower tank 11. At this time, the zinc plate 22 is suspended and does not participate in the zinc melting reaction. The anti-corrosion lifting pump 41 sucks the plating solution and discharges it into the plating tank through the discharge pipe again, forming a cycle to ensure the uniform distribution of the plating solution in the plating tank. The alkaline plating solution above the overflow lower plate 15 flows into the lower tank 11 of the zinc melting tank 1, thereby ensuring the stability of the plating solution concentration in the plating tank, so that the film thickness of the plated workpiece has excellent consistency.

[0039] Manual zinc melting mode:

[0040] The manual plug removal device 4 allows the operator to manually control the opening and closing of the plug body 401, thereby realizing manual control of the zinc melting process.

[0041] Automatic zinc melting mode (based on automatic zinc ion analysis equipment):

[0042] The automatic zinc ion analysis device presets an ideal zinc ion value. The anti-corrosion lifting pump 41 sucks the plating solution and sends it to the automatic zinc ion analysis device, and the device automatically detects the zinc ion content in the plating solution. The analyzed plating solution is sent to the plating tank through the anti-corrosion lifting pump 41. When the detected zinc ion content is lower than the preset value, the device sends a signal, and the automatic plugging device 4 closes the flow port 141. At this time, the plating solution with a higher zinc ion content flows into the lower tank 11 through the overflow lower plate 15, and is then transported to the plating tank by the anti-corrosion lifting pump 41 to achieve automatic replenishment of zinc ions. This process is cyclical to ensure continuous replenishment of zinc ions and uniform distribution of plating solution concentration.

[0043] In this embodiment, by combining the above-mentioned automatic zinc melting equipment, the production efficiency and quality of the zinc plating process can be greatly improved. In the automatic zinc melting mode, the equipment can continuously replenish zinc ions so that the concentration of the plating solution in the plating tank is evenly distributed, thereby ensuring good consistency of the film thickness of the plated workpiece. In the non-melting zinc mode where zinc ions do not need to be replenished, the equipment can achieve the effect of continuous liquid balancing, and also ensure the uniformity of the concentration of the plating solution.

[0044] The manual zinc melting mode provides users with more flexibility, allowing operators to manually control the zinc melting process according to actual needs. The automatic zinc melting mode goes a step further. The zinc ion value is preset by the zinc ion automatic analysis device. The device can automatically detect and analyze the zinc ion content in the plating solution and automatically replenish it as needed. This intelligent operation method can not only reduce manual intervention and improve production efficiency, but also avoid production problems caused by improper operation.

[0045] This automatic zinc melting equipment realizes the automation, efficiency and safety of the galvanizing process through its unique design and functions. At the same time, by combining with the automatic zinc ion analysis equipment, the entire production process is more intelligent, greatly improving production efficiency and product quality. This equipment has a wide range of application prospects in the electroplating, galvanizing and other industries.

[0046] The working principle and use process of the utility model: After the utility model is installed, it works according to the above implementation method until all the working steps are completed.
