Description

Technical Field

[0001] The present disclosure relates to the technical field of waste acid treatment, and in particular to an aluminum profile anodizing waste acid treatment device and a treatment method thereof. Background Art

[0002] At present, in the aluminum anodizing process of aluminum profiles, metal aluminum acts as an anode in an electrolyte, and a layer of aluminum oxide film is formed on its surface through electrolysis. Commonly used electrolytes include sulfuric acid, chromic acid, and oxalic acid. These electrolytes will accumulate a large amount of aluminum ions and other metal ions during use, forming waste acid liquid. If the waste acid liquid is discharged directly, it will cause serious pollution to the soil, water sources and ecosystems. Therefore, it needs to be treated to reduce its pollution to the environment.

[0003] At present, there are many methods for treating waste acid, such as oxidation, extraction, membrane separation and chemical neutralization. The chemical neutralization method mentioned above is the most convenient to use. It only needs to add alkaline solution for stirring, neutralization and filtration. This treatment method has the characteristics of low cost and high efficiency for subsequent treatment, and is generally more widely used. Since the waste acid liquid generated by aluminum anodizing of aluminum profiles contains suspended matter and insoluble impurities, the waste acid liquid is not pre-filtered in the existing neutralization treatment process, resulting in these substances remaining in the waste acid liquid, which is not conducive to the subsequent treatment of the waste acid liquid.

DETAILED DESCRIPTION

[0022] In order to make the purpose, features, and advantages of the present disclosure more obvious and easy to understand, the technical solutions in the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings in the embodiments of the present disclosure. Obviously, the described embodiments are only part of the embodiments of the present disclosure, not all of the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present disclosure.

[0023] Combination Figure 1-10 As shown, an aluminum profile anodizing waste acid treatment device in this embodiment is used to treat the waste acid liquid generated in the anodizing treatment process of the aluminum profile.

[0024] like Figure 1-2 As shown, in this embodiment, an aluminum profile anodizing waste acid treatment device includes a treatment shell 100, wherein a filter chamber 101 and a collection chamber 102 are arranged from top to bottom in the treatment shell 100; A filter assembly, which is disposed in the filter chamber 101 and is used for pre-filtering the waste acid liquid; A treatment mechanism, which is disposed in the collection chamber 102 and is used to communicate with the filter chamber 101 and to neutralize the waste acid liquid entering the treatment component; The treatment mechanism includes a treatment tank 110, the upper end of the treatment tank 110 is provided with a liquid inlet component for communicating with the filter chamber 101, the liquid inlet component can be opened and closed, the treatment tank 110 is provided with a dosing component for dosing medicine into the treatment tank 110, the treatment tank 110 is also provided with a mixing component, the mixing component is used to mix the medicine in the treatment tank 110 with the waste acid liquid, and the mixing component is also provided with a driving component, the mixing component is used to drive the driving component to drive the dosing component to open and close at intervals, so as to achieve the dosing of medicine into the treatment tank 110 at intervals; A floating ring 200, which is disposed in the treatment tank 110 and is used to push the driving assembly upward as the waste acid liquid moves upward, so as to control the driving assembly to release the driving of the dosing assembly; The positioning assembly is disposed in the processing tank 110 and is used to lock and position the upwardly moving driving assembly when the liquid inlet assembly is closed.

[0025] In this embodiment, the upper end of the filter chamber 101 is opened to form a liquid inlet, so that the waste acid liquid can be added into the filter chamber 101, wherein the filter assembly can pre-filter the waste acid liquid added into the filter chamber 101, preliminarily remove suspended matter and insoluble impurities, so that the waste acid liquid can enter the treatment mechanism for neutralization treatment; wherein, through the setting of the collection chamber 102, the waste acid liquid treated by the treatment mechanism can enter the collection chamber 102 for collection; Specifically, a discharge pipe 103 communicating with the collecting chamber 102 is provided at the bottom wall of the processing housing 100 so that the waste acid liquid in the collecting chamber 102 can be discharged and enter the subsequent process for treatment; In this embodiment, the liquid inlet component is set so that it can be opened and closed, so that the waste acid liquid in the filter chamber 101 after pre-filtration treatment can be preferably allowed to enter the treatment tank 110. Specifically, during the process of injecting the waste acid liquid into the treatment tank 110, the mixing component stirs the waste acid liquid in the treatment tank 110, and at the same time, drives the driving component to drive the dosing component to add reagents (such as sodium hydroxide solution) to the treatment tank 110 at intervals, so that the reagents are fully mixed with the waste acid liquid under the action of the mixing component, so that the waste acid liquid is neutralized; wherein, when the waste acid liquid injected into the treatment tank 110 reaches a suitable amount, the liquid inlet component is closed to stop injecting the waste acid liquid into the treatment tank 110. At this time, the floating ring 200 pushes the driving component upward under the action of the waste acid liquid. At this time, the mixing component is released to drive the driving component to drive the dosing component to add reagents at intervals, so that the mixing component can continue to stir the waste acid liquid in the treatment tank 110, so that the waste acid liquid is neutralized; Specifically, a drain pipe 201 for discharging the waste acid liquid in the processing tank 110 into the collecting chamber 102 is provided at the bottom end of the processing tank 110, wherein a solenoid valve is provided on the drain pipe 201. When the processing tank 110 is undergoing a neutralization treatment, the solenoid valve is closed to neutralize the waste acid liquid in the processing tank 110; when the waste acid liquid in the processing tank 110 is neutralized, the solenoid valve is opened to discharge the waste acid liquid in the processing tank 110 into the collecting chamber 102 for collection so as to carry out subsequent processing procedures; It should be noted that when the floating ring 200 pushes the driving assembly to move up to the highest point, the liquid inlet assembly is closed to stop injecting the waste acid liquid into the treatment tank 110. At this time, during the closing process of the liquid inlet assembly, the driving positioning assembly positions the driving assembly that has risen to the highest point to ensure that the position of the driving assembly remains unchanged, that is, to avoid the subsequent electromagnetic valve opening to discharge liquid, when the floating ring 200 moves down and resets, the driving assembly also resets, resulting in the addition of medicine in the liquid adding assembly; When the waste acid liquid needs to be injected into the treatment tank 110 again for neutralization treatment, the solenoid valve is closed. At this time, the liquid inlet assembly is opened to inject the waste acid liquid into the treatment tank 110 again. At this time, the position lock of the driving assembly by the liquid inlet assembly driving positioning assembly is released to reset the driving assembly and cooperate with the mixing assembly; In actual use of this embodiment, in order to increase the processing capacity of the waste acid treatment equipment, multiple processing mechanisms are arranged in the collection chamber 102, and each processing mechanism works independently, so that the waste acid treatment equipment can process the waste acid liquid without stopping, and the processing effect is better.

[0026] like Figure 2 As shown, in this embodiment, the filter assembly includes a filter screen 210 disposed in the filter chamber 101. The filter screen 210 can be used to preferably pre-filter the suspended matter and insoluble impurities in the waste acid liquid.

[0027] In this embodiment, the liquid inlet component includes a liquid inlet pipe 220, which is used to connect the filter chamber 101 and the processing tank 110. A liftable first piston column 310 is provided in the liquid inlet pipe 220, and a flow channel 311 is provided in the first piston column 310. The liquid inlet component also includes a power component, which is used to drive the first piston column 310 to move upward so that its upper end extends into the filter chamber 101 to open the flow channel 311, and the power component is used to drive the first piston column 310 to move downward so that it retracts into the liquid inlet pipe 220 to close the flow channel 311.

[0028] In this embodiment, Figure 3 and Figure 4As shown, a truncated cone-shaped flow guide 401 is formed at the upper end of the liquid inlet pipe 220, and the diameter of the flow guide 401 gradually decreases from top to bottom. The upper end of the flow guide 401 extends outward to form a mounting flange 402, and the mounting flange 402 is used to realize the installation of the liquid inlet pipe 220 and the processing tank 110 on the top wall of the collection chamber 102, wherein the top wall of the collection chamber 102 is provided with a connecting hole connected to the filter chamber 101, and the connecting hole is used to be opposite to the flow guide 401; Among them, through the above-mentioned structure, the upper end of the first piston column 310 moves up to the guide part 401 to open the flow channel 311. At this time, the waste acid liquid in the filter chamber 101 can flow into the treatment tank 110 through the flow channel 311. Because the treatment tank 110 is in a closed state, the air therein can flow into the filter chamber 101 through the flow channel 311 to form bubbles. The bubbles rise in the filter chamber 101, and then impact the suspended matter and insoluble impurities on the filter screen 210, causing them to flip and not easily adhere to the filter screen 210, thereby ensuring the filtering effect of the filter screen 210; when the lower end of the first piston column 310 moves down and retracts into the liquid inlet pipe 220, at this time, the flow channel 311 is closed, thereby stopping the injection of waste acid liquid into the treatment tank 110; The lifting and lowering of the first piston column 310 is realized by a power member; Specifically, the power component includes a cylinder 250, which is used to drive the first piston column 310 to rise and fall, wherein the cylinder 250 is relatively installed on the mounting flange 402, and the output shaft of the cylinder 250 extends into the filter chamber 101. The output shafts of the cylinder 250 are connected by a connecting frame 340, and a connecting column connected to the first piston column 310 is relatively arranged on the connecting frame 340, thereby enabling the cylinder 250 to better drive the first piston column 310 to rise and fall.

[0029] In this embodiment, the mixing assembly includes a rotating shaft 230 rotatably disposed in the processing tank 110, the upper end of the rotating shaft 230 passes through the first piston column 310 and extends into the filter chamber 101, an inner stirring plate 231 is provided on the rotating shaft 230 located in the processing tank 110, and an outer stirring plate 232 is provided at the end of the rotating shaft 230 passing through the first piston column 310 and extending out.

[0030] During actual use of this embodiment, a motor 260 for driving the rotating shaft 230 is provided at the bottom end of the treatment tank 110. The motor 260 drives the rotating shaft 230 to rotate, thereby driving the inner stirring plate 231 to rotate, thereby stirring and mixing the waste acid liquid and the reagent in the treatment tank 110. At the same time, the outer stirring plate 232 can be driven to rotate, so that it can break up the rising bubbles, thereby increasing the area of ​​the bubbles contacting the filter screen 210, so that the suspended matter and insoluble impurities on the filter screen 210 are turned over, and the filtering effect of the filter screen 210 is better guaranteed.

[0031] In this embodiment, the dosing component includes a horizontal tube 320 and a vertical tube 330 that are perpendicular to each other and connected. The upper end of the vertical tube 330 is used to connect to the drug supply tube 331, and the lower end is connected to the treatment tank 110 through the connecting tube 332. One end of the horizontal tube 320 is installed on the outer wall of the treatment tank 110. A second piston column 520 is provided in the horizontal tube 320 through a first spring 510. A push rod 521 extending into the treatment tank 110 is provided on one end surface of the second piston column 520. A through hole 522 corresponding to the vertical tube 330 is provided on the second piston column 520. The first spring 510 is used to drive the second piston column 520 to move so that the vertical tube 330 and the through hole 522 are misaligned. The driving component is used to cooperate with the push rod 521 to realize the through hole 522 and the vertical tube 330 to be spaced relative to each other.

[0032] In this embodiment, the processing housing 100 is further provided with a medicine storage tank (not shown in the figure), the medicine storage tank is used to store medicine, and the medicine supply pipe 331 is used to connect the medicine storage tank. The medicine storage tank has a certain pressure, and the medicine in it can be pressed into the corresponding medicine adding component through the medicine supply pipe 331; Among them, combined Figure 5 As shown, the opening of the horizontal tube 320 is set toward the other end, and a plug 500 is threadedly installed at the opening, thereby realizing the installation of the second piston column 520 and the first spring 510 therein, wherein the first spring 510 is used to drive the second piston column 520 to move so that the through hole 522 and the vertical tube 330 are misaligned. At this time, the dosing component is closed, and at the same time, the push rod 521 extends into the treatment tank 110. When the driving component drives the push rod 521 to retract, so that the through hole 522 and the vertical tube 330 are opposite, at this time, the dosing component is opened, and at this time, the agent is added into the treatment tank 110 through the connecting tube 332 to complete the dosing.

[0033] In this embodiment, the driving assembly includes a driving ring 240 which is sleeved outside the rotating shaft 230 and can be raised and lowered. The rotating shaft 230 rotates to drive the driving ring 240 to rotate. The outer wall of the driving ring 240 is provided with convex rings 610 along its circumferential direction. Both ends of the convex ring 610 form guiding inclined surfaces 611 for the ejector rod 521 to slide in or out. The rotating shaft 230 is provided with a second spring 620 for pushing the driving ring 240 to move downward. The driving ring 240 moves downward to make the push rod 521 and the convex ring 610 face each other. The floating ring 200 is sleeved outside the rotating shaft 230. The floating ring 200 moves upward to push the driving ring 240 to move upward, so that the push rod 521 and the convex ring 610 are misaligned.

[0034] In actual use, this embodiment is combined with Figure 6-8As shown, brackets 810 are relatively installed inside the driving ring 240, and the rotating shaft 230 is arranged to penetrate the brackets 810. Relative connecting plates 710 are installed on the rotating shaft 230 between the brackets 810. The ends of the connecting plates 710 that are far away from each other are provided with limiting grooves 711. The inner side wall of the driving ring 240 is relatively provided with limiting blocks 811 along the axial direction of the rotating shaft 230. The limiting blocks 811 are located in the corresponding limiting grooves 711 and slide, so that the rotating shaft 230 rotates to drive the driving ring 240 to rotate. At the same time, the driving ring 240 can move up and down along the rotating shaft 230. The upper and lower sides of the convex ring 610 are also provided with matching inclined surfaces, so that when the driving ring 240 is lifted or lowered, the push rod 521 slides up or down the convex ring 610 along the matching inclined surfaces; specifically, when a retaining ring 701 is provided on the rotating shaft 230, it is used to install the second spring 620, so that one end of the second spring 620 abuts against the retaining ring 701, and the other end abuts against the bracket 810, so that it pushes the driving ring 240 to move downward, so that the convex ring 610 and the push rod 521 correspond to each other, that is, the two are on the same horizontal plane. At this time, the rotation of the rotating shaft 230 drives the driving ring 240 to rotate, so that the push rod 521 slides into or slides away from the convex ring 610 along the guide inclined surface 611, thereby realizing the interval dosing of the dosing assembly; The convex ring 610 has a certain curvature, so that when the top rod 521 slides along the convex ring 610, the dosing component can remain open to add reagents into the processing tank 110. The interval dosing method can better avoid excessive addition of reagents and cause waste of reagents.

[0035] Specifically, the floating ring 200 is sleeved on the outside of the rotating shaft 230. When the floating ring 200 moves up to squeeze the bracket 810, the driving ring 240 moves up, driving the convex ring 610 to move up and disengage from the push rod 521. At this time, the rotation of the driving ring 240 will not drive the dosing assembly to open and close, that is, the dosing stops.

[0036] In this embodiment, the inner side wall of the driving ring 240 is provided with a clamping groove 601 at the upper end along its circumference; The positioning assembly includes a positioning block 910 relatively arranged on the top wall of the processing tank 110, and a cavity 1001 with an opening toward the liquid inlet pipe 220 is provided in the positioning block 910. A positioning tongue 920 with one end extending out is provided in the cavity 1001 through a third spring 1010, and a positioning rod 930 penetrating the positioning block 910 is provided at the other end of the positioning tongue 920. A driving inclined surface 921 is provided on the protruding end of the positioning tongue 920 and located on the upper side surface. The first piston column 310 moves downward to squeeze the driving inclined surface 921 at its lower end to retract the positioning block 910, thereby driving the positioning rod 930 to extend into the slot 601, thereby positioning the upward-moving driving ring 240.

[0037] In actual use of this embodiment, when the floating ring 200 moves upward to push the driving ring 240 to move upward to the highest point, the upper end of the driving ring 240 abuts against the upper side wall of the processing tank 110. At this time, the first piston column 310 moves downward to close the liquid inlet assembly. During this process, the lower end of the first piston column 310 moves downward to squeeze the driving inclined surface 921 to retract the positioning tongue 920, thereby pushing the positioning rod 930 to extend into the card slot 601, thereby positioning the driving ring 240 so that it will not be reset under the action of the second spring 620. Specifically, in order to timely control the first piston column 310 to move downward to close the liquid inlet assembly when the floating ring 200 moves upward to the highest point, in this embodiment, a pressure sensor for cooperating with the driving ring 240 is provided on the top wall of the processing tank 110, and the pressure sensor is electrically connected to a controller. When the driving ring 240 moves upward to squeeze the pressure sensor so that the pressure sensor detects a pressure signal, the controller controls the cylinder 250 to drive the first piston column 310 to move downward, and then automatically controls the positioning assembly to position the driving ring 240. When the cylinder 250 drives the first piston column 310 to move upward, the liquid inlet assembly is opened, so that the waste acid liquid in the filter chamber 101 enters the treatment tank 110. At this time, the first piston column 310 will not squeeze the driving inclined surface 921, so that under the action of the third spring 1010, the positioning tongue 920 and the positioning rod 930 are reset, and the positioning of the driving ring 240 is released, so that it is reset under the action of the second spring 620, so that it can drive the dosing assembly to open and close again; Among them, the upper end of the positioning block 910 extends outward to form a fixing portion 911, and the fixing portion 911 is fixedly installed at the upper end of the processing tank 110 by screws so that the positioning tongue 920 cooperates with the first piston column 310. Specifically, in order to install the positioning tongue 920 and the positioning rod 930 in the positioning block 910, the positioning rod 930 is externally threaded with a nut 940. When the nut 940 cooperates with the end of the positioning block 910, the positioning tongue 920 and the positioning rod 930 are installed in the positioning block 910.

[0038] The present invention also provides a method for treating waste acid from anodizing of aluminum profiles, which uses the above-mentioned waste acid treatment equipment and specifically comprises the following steps: S1, driving the first piston rod 310 downward by the cylinder 250 to close the liquid inlet assembly and add the waste acid liquid to be treated into the filter chamber 101; S2, the corresponding first piston rod 310 is driven upward by the cylinder 250 to open the liquid inlet assembly. At this time, the waste acid liquid filtered by the filter screen 210 in the filter chamber 101 enters the treatment tank 110. During this process, the motor 260 drives the rotating shaft 230 to rotate, so that the dosing assembly adds the agent to the treatment tank 110 at intervals, and at the same time, the mixing assembly mixes and stirs the waste acid liquid and the agent in the treatment tank 110; S3, the waste acid liquid entering the treatment tank 110 can drive the floating ring 200 to push the driving ring 240 to move upward. When the floating ring 200 pushes the driving ring 240 to move upward to the top wall of the treatment tank 110, the cylinder 250 drives the first piston column 310 to descend, so that the liquid inlet component is closed to complete the quantitative addition of the waste acid liquid into the treatment tank 110. At this time, the positioning component positions the driving ring 240 so that the rotation of the driving ring 240 will not drive the dosing component to open and close for dosing. At this time, the waste acid liquid is neutralized in the treatment tank 110; S4, discharging the waste acid liquid in the treatment tank 110 after treatment into the collection chamber 102 for collection; S5. Repeat steps S2-S4 to preferably neutralize the waste acid liquid in the filter chamber 101.
