[0001] The present invention belongs to the technical field of metal material surface treatment technology and equipment. More specifically, the present invention relates to a surface chemical treatment tank structure for aluminum parts. Background Art

[0002] The surface treatment of large aluminum parts has a wide range of uses in industry. With the development of process technology, the requirements for the surface oxide film treatment of aluminum parts are getting higher and higher.

[0003] The flat chemical treatment tank for aluminum materials and the matching flat hoist play a vital role in the entire surface treatment process. In the prior art, aluminum parts products adopt a technical solution of vertically entering the tank body for reaction, and the bottom gas agitator is used to achieve the uniformity of product surface temperature and liquid concentration, thereby meeting the requirement of removing residual film. However, when processing large aluminum anodes, due to the deep tank body, the effect of the gas agitator will gradually weaken when stirring from the bottom to the top, resulting in the inability to effectively control the uniformity of the reaction; the opening area is large, the vertical tank product is hoisted high, the product has a long moving path between the tanks, and the surface liquid volatilization is large, resulting in waste of liquid and reduced efficacy.

[0004] The following search results were obtained by searching the existing public technical literature using keywords such as "aluminum parts; chemistry; surface; treatment; groove":

[0005] 1. Chinese patent document: "A method for making wood-grain aluminum alloy profiles", patent (application) number: 201810095398.X, the technical solution recorded is:

[0006] "The method for making a wood grain aluminum alloy profile is to firstly perform surface treatment on the aluminum alloy profile; then electrostatically spray transfer primer on the surface of the aluminum alloy profile and solidify it, so that an extremely thin aluminum oxide film (0.01-0.02um) is easily formed on the surface of the aluminum alloy";

[0007] The technical effects recorded are:

[0008] "It has a certain degree of corrosion resistance, the method is simple, and it improves the paint film hardness, wear resistance, impact resistance, hydrochloric acid resistance and other properties.

It is useful in increasing the adhesion between the wood grain and the alloy profile in subsequent processes, as well as the corrosion resistance and weather resistance of the wood grain. The design is novel."

[0011] The technical effects recorded are:

[0012] "The surface of aluminum alloy profiles has both high hardness and strength, and a bright color that can be maintained for a long time."

[0013] However, the technical solutions recorded in the above-mentioned existing public technical documents and the technical solutions currently in public application have failed to solve the problems and defects of the prior art, namely, "the uniformity of the reaction cannot be effectively controlled; the product movement path is long, the amount of surface drug liquid volatilization is large, the drug liquid is wasted and the efficacy is reduced." Summary of the invention

[0034] The specific implementation modes of the present invention are further explained in detail below by describing the embodiments with reference to the accompanying drawings, so as to help those skilled in the art to have a more complete, accurate and in-depth understanding of the inventive concept and technical solution of the present invention.

[0035] like Figures 1 to 4 The structure of the present invention is a chemical treatment tank structure for the surface of an aluminum component, including a chemical treatment tank 1, a cleaning tank 2 and a hanger 10, and the aluminum component is fixed on the horizontal bearing surface of the hanger 10.

[0036] The aluminum component is placed horizontally in the chemical treatment tank 1 to ensure uniform reaction with the chemical solution.

[0037] In order to solve the problems existing in the prior art and overcome its defects, and to achieve the invention purpose of improving the uniformity of the reaction, reducing energy consumption and loss of the liquid medicine, the technical solution adopted by the present invention is:

[0038] like Figure 1 As shown, the surface chemical treatment tank structure of the aluminum component of the present invention, the chemical treatment tank 1 and the cleaning tank 2 are distributed on the same horizontal plane in the height direction.

[0039] Figure 1 The upper part is a front view of the structure of the chemical treatment tank for the surface of the aluminum component of the present invention; Figure 1 The lower part is a top view thereof.

[0040] The novel large aluminum component horizontal hoisting and planar chemical treatment tank, chemical cleaning tank and matching planar hoisting device design of the present invention can not only solve the problem of uneven surface reaction of vertical chemical treatment of large aluminum components, but also have low cost and energy consumption, and are better in operation and environmental safety.

[0041] Operation and environmental safety of planar chemical treatment tanks: vertical tanks have high product hoisting, long product movement paths between tanks, and large surface liquid volatilization; planar tanks have low product hoisting, short product movement paths between tanks, and less surface liquid volatilization; and planar tanks have low hoisting, so transfer can be done at the bottom of the tank cover, reducing the volatilization and diffusion of liquid into the environment. Cost reduction: the demand for liquid in a planar tank is 1 / 3-1 / 2 less than that of a vertical tank, and the energy consumption for heating and cooling the liquid is low; in addition, the cost of emission treatment equipment can also be reduced, and the pollution to the outside of the tank area is reduced after the product is rinsed in the cleaning tank.

[0042] The specific analysis is as follows:

[0043] like Figure 1 As shown:

[0044] There are two or more chemical treatment tanks 1 distributed outside the side of the cleaning tank 2.

[0045] The chemical treatment tank 1 and the cleaning tank 2 are both distributed on the same horizontal plane, so the movement and operation of the sling are more convenient and more efficient.

[0046] like Figure 2 As shown:

[0047] The sling 10 is provided with a suspension rod, and the bottom end of the suspension rod is fixedly connected to the horizontal bearing surface of the sling 10. The suspension rod of the sling 10 is provided with a lifting height adjustment and fixing mechanism.

[0048] Figure 2 The lower left part of the figure is the main view of the spreader; the upper part is the top view of the spreader; the right part is the side view of the spreader. A and B in the figure indicate its running direction. C indicates the lifting height adjustment and fixing mechanism of the spreader.

[0049] Special lifting equipment for horizontal surface treatment of aluminum parts can adapt to all 6G and 8.6G products by adjusting the horizontal lifting rod. It has a simple structure and high efficiency.

[0050] like Figure 3 As shown:

[0051] An opening 8 is provided on the top cover of the chemical treatment tank 1 from the edge facing the cleaning tank 2 to the center thereof, and the width of the opening 8 is greater than the cross-sectional dimension of the suspension rod.

[0052] Figure 3 The lower left part in the figure is a front view of the chemical treatment tank 1; the upper part is a top view of the chemical treatment tank 1; and the right part is a side view of the chemical treatment tank 1.

[0053] The opening 8 of the top cover for processing products is a passage for the lifting rod of the lifting device 10 to enter and exit the chemical treatment tank 1.

[0054] like Figure 4 As shown:

[0055] A cross-shaped opening 9 is provided on the top cover of the cleaning tank 2, and the opening width of the cross-shaped opening 9 is larger than the cross-sectional dimension of the suspension rod.

[0056] The cross-shaped opening 9 is a passage for the suspension rod of the sling 10 to enter and exit the cleaning tank 2. The cleaning tank 2 can be entered and exited from four directions.

[0057] like Figure 1 and Figure 3 As shown:

[0058] In the chemical treatment tank 1, the liquid medicine is introduced into the bottom of the chemical treatment tank 1 through a pipeline; the liquid medicine is evenly dispersed on the horizontally placed aluminum parts for reaction through a gas stirring device; the pipeline includes a bottom water tank air pipeline and a pipeline for solution filtration and circulation, namely the air pipeline at the bottom of the water tank and the solution filtration circulation pipeline 3 in the figure.

[0059] The air pipe is arranged at the bottom of the chemical treatment tank 1 to ensure the effectiveness and uniformity of stirring.

[0060] A heater 4 and a temperature sensor are arranged on the top cover of the chemical treatment tank 1 .

[0061] The heater 4 and the temperature sensor are used to heat the solution and control the temperature.

[0062] like Figure 1 As shown:

[0063] An exhaust pipe 5 and an exhaust hood are arranged around the aluminum component surface chemical treatment tank structure.

[0064] The exhaust pipes 5 and exhaust hoods for collecting chemical mist arranged around can effectively eliminate the influence of chemical mist on the environment and operators.

[0065] like Figure 1 and Figure 4 As shown:

[0066] The cleaning tank 2 is provided with a single column 6 for supporting its top cover, and a spray pipe and a spray head 7 are provided inside the top cover.

[0067] A spray device is designed in the cleaning tank 2, namely a spray pipe and a spray head 7 inside the top cover, to reduce the pollution to other areas after leaving the tank.

[0068] Working principle and process of the present invention:

[0069] 1. The aluminum parts are fixed on a special lifting device for horizontal surface treatment, lifted to the chemical treatment tank (i.e. chemical treatment tank 1) and placed horizontally;

[0070] 2. The liquid medicine is passed through a pipeline to the bottom of the chemical treatment tank 1 and evenly dispersed on the horizontally placed aluminum parts for reaction;

[0071] 3. In the cleaning tank 2, aluminum parts can be placed in from four directions and sprayed after cleaning to meet the cleaning requirements to the greatest extent.

[0072] Compared with the prior art, the specific technical effects and technical progress achieved by the present invention are:

[0073] 1. In the above process, the product is placed horizontally in the chemical treatment tank, and the overall distance is close to the bottom, the liquid level requirement of the liquid is low, the gas stirring stroke is short, and the stirring effect is good; the liquid is sprayed evenly from the bottom, and with the effective gas stirring effect, the liquid difference in different parts of the product surface is small, and it can effectively take away the heat generated by the chemical reaction on the surface of the component, making the surface temperature of the component uniform;

[0074] 2. The product is hoisted horizontally at a low height. The moving path is short when transferring the liquid medicine to the cleaning tank after treatment, and the surface liquid medicine evaporates less. The transfer can be carried out at the bottom of the tank cover to reduce the release of medicine mist into the environment. Compared with the opening area of ​​the vertical treatment tank, the opening area of ​​the horizontal treatment tank is reduced by 56%;

[0075] 3. The product is hoisted at a low height, effectively ensuring the safety of operators;

[0076] 4. In the above-mentioned anodizing process, the liquid level requirement of the chemical solution is low, the required amount of chemical solution is small, and the energy consumption for heating and cooling the chemical solution is low, thereby reducing production costs. In addition, the cost of the discharge treatment equipment can also be reduced. Compared with the vertical treatment tank of the prior art, the chemical solution required by the horizontal treatment tank of the present invention is reduced by 40%.

[0077] The above is an exemplary description of the present invention in conjunction with the accompanying drawings. It is obvious that the specific implementation of the present invention is not limited to the above-mentioned method. As long as various non-substantial improvements are made using the concept and technical solution of the present invention, or the concept and technical solution of the present invention are directly applied to other occasions without improvement, they are all within the protection scope of the present invention.
