Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of zinc melting, in particular to an automatic zinc melting equipment. BACKGROUND

[0002] In the galvanizing process, the use of zinc plating melt is crucial. However, due to the instability of zinc ions, the control of its concentration becomes a daunting task. Traditionally, this task relies entirely on manual operation, which undoubtedly increases the complexity and uncertainty of the galvanizing process.

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

[0004] However, this completely manual operation method not only takes time and effort, but also has many drawbacks. First, when manually analyzing the zinc ion concentration, due to various factors such as the operator's experience, skill level, fatigue level, etc., it is difficult to ensure the accuracy and stability of the analysis. This will result in large fluctuations in the concentration of zinc ions in the zinc plating melt, which will affect the quality of the galvanized products.

[0005] Secondly, manual operation also has certain safety hazards. During the operation, the operator needs to come into contact with harmful substances such as alkaline plating solution, which can easily cause harm to the human body if appropriate protective measures are not taken. In addition, frequent travelling crane operation and zinc melting basket replacement will also increase the labor intensity and safety risk of the operator.

[0006] In the existing process, the zinc melting basket needs to be suspended at a high place. Although this can prevent the zinc ion concentration from being too high, it has two major safety hazards. First, the suspension operation itself is dangerous; second, employees often forget to raise it when they leave work, resulting in excessive zinc ion concentration the next day, which seriously affects product quality.

[0007] Therefore, based on the above technical problems, it is necessary for those skilled in the art to develop an automatic zinc melting equipment. SUMMARY

[0008] The purpose of the present application is to provide an automatic zinc melting equipment to solve the problems commonly existing in the background art.

[0009] In order to achieve the above object, the present application provides the following technical scheme: an automatic zinc melting equipment, comprising a zinc melting tank, a partition bottom plate arranged in the zinc melting tank, an upper zinc melting tank arranged above the partition bottom plate, and a lower tank arranged below the partition bottom plate, a plurality of zinc melting baskets arranged in the upper zinc melting tank, a zinc plate arranged in each zinc melting basket, an alkaline plating solution overflow pipe arranged on the left side of the zinc melting tank and communicated with the upper zinc melting tank, a plug pulling device arranged in the upper zinc melting tank, a plug body arranged at the bottom of the plug pulling device, and a flow-through opening arranged on the partition bottom plate in correspondence.

[0010] As a preferred technical scheme, the partition bottom plate is provided with a plurality of partition supports for supporting, the plurality of partition supports are distributed at equal intervals and fixedly connected with the zinc melting tank.

[0011] As a preferred technical scheme, the zinc plate arranged in the zinc melting basket can be horizontally placed, vertically placed or obliquely placed, and the zinc melting basket is an iron frame, wherein the oblique placement has the largest contact area and the best effect.

[0012] As a preferred technical scheme, the plug pulling device is a manual plug pulling device or an automatic plug pulling device, wherein the automatic plug pulling device can adopt a cylinder lifting, a lead screw lifting, an electric cylinder or a worm gear lifting.

[0013] As a preferred technical scheme, the upper zinc melting tank is provided with a baffle in a symmetrical manner, and overflow lower plates are arranged outside the two baffles.

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

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

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

[0017] As a preferred technical scheme, the baffle is used to block floating oil and other suspended matters on the surface of the plating solution, and facilitates cleaning.

[0018] Compared with the prior art, the present application has the following beneficial effects:

[0019] (1) The present application is an automatic zinc melting equipment, which is provided with a separation bottom plate in the upper zinc melting tank to separate the upper zinc melting tank into independent spaces, and a zinc melting basket is arranged in each space. Zinc plates in the zinc melting basket react with 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 generation amount of zinc ions can be accurately controlled. After the reaction, the plating solution with high zinc ion content flows into the separation tank through overflow. The floating oil and other suspended matters on the surface of the plating solution are blocked by the separation plate and float above the liquid surface, which is convenient for cleaning to maintain the purity of the plating solution.

[0020] (2) The present application is an automatic zinc melting equipment, which has multiple working modes, including automatic zinc melting mode, non-zinc melting mode and manual zinc melting mode. The corresponding mode can be selected for operation according to actual needs. In the automatic zinc melting mode, the zinc ion automatic analysis equipment can automatically detect the content of zinc ions in the plating solution. When the content of zinc ions is lower than the preset value, the zinc melting and non-zinc melting actions are realized by opening and closing control of the flow port, so as to control the replenishment of zinc ions and maintain the stability of the zinc ion concentration in the plating solution.

[0021] (3) The present application is an automatic zinc melting equipment, which has the advantages of simple structure, convenient operation, safety and reliability. By arranging the separation bottom plate and the zinc melting basket, the safety hidden danger caused by the traditional basket hoisting method can be effectively solved. This method has operation risks and easily leads to fluctuation of zinc ion concentration, which seriously affects the product quality. The new design not only simplifies the addition and replacement process of zinc plates, reduces the labor intensity of operators, but also significantly reduces the safety risk and ensures the stability and safety of the production process. At the same time, the equipment can also realize the functions of continuous liquid equalization and purification of plating solution, improving the quality and production efficiency of galvanized products. The automatic zinc melting equipment can be widely applied in the galvanizing production process to realize automatic, efficient and safe production. BRIEF DESCRIPTION OF DRAWINGS

DETAILED DESCRIPTION

[0028] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application.

[0029] In the following description, many specific details are set forth in order to provide a thorough understanding of the present application. However, the present application can be practiced in a variety of ways beyond the specific embodiments described herein without departing from the scope of the present application, and it is therefore intended that such changes and modifications be included within the scope of the present application.

[0030] EMBODIMENT

[0031] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 , the present application provides a kind of automatic zinc melting equipment technical scheme: including zinc melting groove 1, zinc melting groove 1 inside is equipped with separation bottom plate 13, the bottom of this bottom plate is equipped with multiple evenly distributed separation support 12, they are closely connected with zinc melting groove 1, to ensure stability.Separation bottom plate 13 is equipped with upper layer zinc melting groove 14 above, and lower layer groove 11 below.In upper layer zinc melting groove 14, multiple groups of zinc melting baskets 21 are placed, and zinc plate 22 is placed in each zinc melting basket 21.These zinc plates 22 can be placed in horizontal, vertical or inclined manner according to requirements, and the zinc melting basket 21 is iron frame, wherein the contact area of the inclined placement is maximum, and the effect is best.

[0032] Alkaline plating solution overflow pipe 3 is arranged on the left side of zinc melting groove 1, and the pipe is connected with upper layer zinc melting groove 14, so as to realize smooth flow of liquid.A plug pulling device 4 is arranged in upper layer zinc melting groove 14, and the device can be manually or automatically operated.Among them, automatic plug pulling mode can adopt air cylinder lifting, screw rod lifting, electric cylinder or worm gear lifting mechanism.The bottom of plug pulling device 4 is provided with plug body 401.

[0033] The partition bottom plate 13 is provided with a flow-through port 131 to facilitate smooth exchange of fluid. The plug body 401 is in the shape of a circular truncated cone and abuts against the flow-through port 131 to open and close the flow-through port 131, thereby achieving the functions of sealing and opening. The upper zinc melting tank 14 is internally provided with partition plates 16 in a symmetrical manner, which are used to block floating oil and other suspended matters on the surface of the plating solution, thereby facilitating cleaning. Meanwhile, overflow lower plates 15 are provided on the outer sides of the two partition plates 16 to control the flow direction of the fluid. The zinc melting tank 1 is externally provided with a corrosion-resistant lifting pump 41, which is connected to the lower tank 11 through a suction pipe 42 and discharges the treated fluid through a discharge pipe 43. The tail end of the discharge pipe 43 is connected to a plating tank, and a zinc ion analysis device is installed in the plating tank to monitor and analyze the composition of the fluid in real time.

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

[0035] The alkaline plating solution flows into the inlet of the upper zinc melting tank 14 through the alkaline plating solution overflow pipe 3. The automatic plug pulling device 4 controls the plug body 401 to be pressed down, at which time the flow-through 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, and a zinc melting reaction occurs between the zinc plate 22 and the alkaline plating solution, thereby increasing the zinc ion concentration. After the reaction, the plating solution with high zinc ion content flows into the separation tank partition plate 16 through the overflow lower plate 15, wherein the floating oil and other suspended matters on the surface of the plating solution are blocked by the partition plate and float above the liquid surface, thereby facilitating cleaning and maintaining the purity of the plating solution.

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

[0037] Zinc melting mode (zinc ion replenishment mechanism):

[0038] The automatic plug pulling device 4 controls the plug body 401 to be lifted up, and the flow-through port 131 of the partition bottom plate 13 in the upper zinc melting tank 14 is opened. All alkaline plating solution directly flows into the lower tank 11, at which time the zinc plate 22 is suspended and does not participate in the zinc melting reaction. The corrosion-resistant lifting pump 41 sucks the plating solution and discharges it into the plating tank again through the discharge pipe, thereby forming a cycle to ensure 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, and thus ensuring excellent consistency of the film thickness of the plated workpiece.

[0039] Manual zinc melting mode:

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

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

[0042] The zinc ion automatic analysis equipment presets the ideal zinc ion value. The anticorrosion lifting pump 41 sucks and sends the plating solution to the zinc ion automatic analysis equipment, and the equipment automatically detects the content of zinc ions in the plating solution. The analyzed plating solution is sent to the plating tank through the anticorrosion lifting pump 41. When the detected zinc ion content is lower than the preset value, the equipment sends a signal, and the automatic plug device 4 closes the flow port 141. At this time, the plating solution with 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 anticorrosion lifting pump 41, so as to realize automatic replenishment of zinc ions. The process is repeated to ensure continuous replenishment of zinc ions and uniform distribution of plating solution concentration.

[0043] In the 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 plating solution concentration in the plating tank is uniformly distributed, thereby ensuring good film thickness consistency of the plated workpiece. In the non-zinc melting mode without zinc ion replenishment, the equipment can realize the function of continuously uniform liquid, and also ensure the uniformity of the plating solution concentration.

[0044] The manual zinc melting mode provides more flexibility for the user, allowing the operator to manually control the zinc melting process according to actual needs. The automatic zinc melting mode is further improved by presetting the zinc ion value through the zinc ion automatic analysis equipment. The equipment can automatically detect and analyze the content of zinc ions in the plating solution, and automatically replenish as needed. This intelligent operation method not only reduces manual intervention and improves production efficiency, but also avoids production problems caused by improper operation.

[0045] The automatic zinc melting equipment realizes the automation, high efficiency and safety production of the zinc plating process through its unique design and function. At the same time, by combining the zinc ion automatic analysis equipment, the entire production process is more intelligent, greatly improving the production efficiency and product quality. The equipment has a wide application prospect in the fields of electroplating and zinc plating.
