Description

Technical Field

[0001] This utility model relates to the field of aluminum profile processing technology, specifically to an aluminum profile mirror polishing device. Background Technology

[0002] Mirror polishing is a process that uses mechanical or chemical methods to treat the surface of an object to achieve an extremely high degree of smoothness. Mirror polishing of aluminum profiles mainly targets their surface and specific functional areas. For example, mirror polishing the inner walls of aluminum pipes used to transport food or pharmaceutical liquids can prevent material residue, meet hygiene standards, and reduce fluid resistance.

[0003] When chemically polishing the inner wall of an aluminum pipe, a chemical solution is flowed through the pipe. The chemical reaction between the aluminum surface and the chemical solution (such as a mixture of phosphoric acid, sulfuric acid, and nitric acid) selectively dissolves the surface peaks, thus gradually polishing the inner wall of the pipe.

[0004] When performing chemical treatment, tapered fittings are often inserted into the pipe ports for connection. To improve the contact effect between the chemical liquid and the pipe wall, mechanical vibration is often introduced during the treatment. However, in practical applications, there is an unavoidable risk of chemical liquid leakage and dripping at the connection between the fitting and the pipe. Utility Model Content

[0005] (I) Technical Issues

[0006] The present invention aims to at least solve the problem in the prior art where leaks or drips of chemical liquids can contaminate other parts of equipment or the ground, causing corrosion or pollution.

[0007] (II) Technical Content

[0008] This solution provides an aluminum profile mirror polishing device, achieved through the following specific technical means: including...

[0009] A support frame on which chemical liquid storage tanks and chemical liquid recovery tanks are mounted;

[0010] The vibration clamping mechanism includes a mounting frame fixed on a support frame, and a tapered joint symmetrically arranged at both ends of the mounting frame. An elastic support is connected between the joint and the mounting frame. Both sets of joints are tapered and inserted into the two ends of the pipe. The two sets of joints are respectively connected to a chemical liquid storage tank and a chemical liquid recovery tank.

[0011] A protective cover is installed on the outside of the joint to provide a surrounding protection at the connection between the joint and the pipe, and is used to catch chemical liquids flowing out from the connection.

[0012] Preferred technical solution 1: It also includes a temporary storage box, and multiple sets of the protective covers are connected to the temporary storage box through hoses to collect the chemical liquid flowing out of the connection.

[0013] Preferred technical solution 2: Two sets of sliding blocks are slidably distributed at both ends of the slide rail opened on the mounting frame, and the elastic support members on the two sets of joints are respectively installed on the two sets of sliding blocks.

[0014] Preferred technical solution 3: The elastic support includes a frame fixed on the slide and perpendicular to the mounting bracket, a movable seat that slides on the frame, and a joint fixedly installed on the movable seat. Support springs are connected between the upper and lower sides of the movable seat and the upper and lower ends of the frame. A vibration motor is also installed on each set of movable seats to provide vibration force.

[0015] Preferred technical solution four: The chemical liquid storage tank and the chemical liquid recovery tank are connected by a pipeline, and a filter is installed on the connecting pipeline between the two. The chemical liquid circulates between the vibration clamping mechanism, the pipeline, the chemical liquid storage tank and the chemical liquid recovery tank.

[0016] (III) Technical Effects

[0017] The above structure gives this solution the following advantages:

[0018] Traditional chemical polishing of pipelines often uses rigid clamping, which can easily lead to loosening and leakage of the joints during vibration, and it is difficult to ensure that the inner wall of the pipeline is in full contact with the chemical liquid. The combination of "conical joint + elastic support + protective cover" in this solution not only achieves adaptive sealing for different pipe diameters through the conical structure, but also uses the elastic support in conjunction with the vibration motor to ensure that the pipeline is evenly stressed during vibration, while the protective cover accurately intercepts the leaking liquid, forming a closed-loop solution of "clamping-vibration-leakage prevention".

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1 An aluminum profile mirror polishing device includes a support frame 1 and a vibration clamping mechanism 4, wherein:

[0027] A chemical liquid storage tank 2 and a chemical liquid recovery tank 3 are installed on the support frame 1. The chemical liquid storage tank 2 and the chemical liquid recovery tank 3 are connected by a pipe, and a filter 6 is installed on the connecting pipe to filter the chemical liquid entering the chemical liquid storage tank from the chemical liquid recovery tank 3.

[0028] The vibration clamping mechanism 4 is installed below the support frame 1 and is used to clamp the pipe to be treated and drive the clamped pipe to vibrate. The vibration clamping mechanism 4 includes a mounting frame 41 fixed on the support frame 1 and a tapered connector 45 symmetrically arranged at both ends of the mounting frame 41 (the tapered surface of the connector 45 is covered with a 1-2mm thick chemical corrosion resistant silicone pad). An elastic support member 44 is connected between the connector 45 and the mounting frame 41. Both sets of connectors 45 are tapered and inserted into the two ends of the pipe. The interfaces at the tail ends of the two sets of connectors 45 are respectively connected to the chemical liquid storage tank 2 and the chemical liquid recovery tank 3 via hoses. The chemical liquid is pumped out from the pump body on the chemical liquid storage tank 2 and enters the pipe through the vibration clamping mechanism 4 to chemically treat the pipe. The treated chemical liquid then flows back to the chemical liquid recovery tank 3. The chemical liquid circulates between the vibration clamping mechanism 4, the pipe, the chemical liquid storage tank 2, and the chemical liquid recovery tank 3.

[0029] To prevent leakage at the connection between the joint 45 and the pipe during vibration, or to prevent the dripping of small amounts of accumulated chemical liquid at the connection when the joint 45 is separated from the pipe, a protective cover 46 is provided on the outside of the joint 45. The protective cover 46 protects the connection between the joint 45 and the pipe and is used to catch the chemical liquid flowing out from the connection. Specifically:

[0030] The protective cover 46 has a C-shaped longitudinal section. The rear wall is fixedly sleeved on the tail end of the connector 45, and the front wall opening is located at the front end of the connector 45, with its axis coinciding with the axis of the connector 45. At the same time, the diameter of the opening is larger than the outer diameter of the pipe, which facilitates the pipe end to pass through the opening into the protective cover 46 during installation and to be inserted into the conical front section of the connector 45. During polishing, chemical liquids dripping from the connection point due to various reasons fall into the protective cover 46 for collection.

[0031] In one set of embodiments

[0032] Please see Figure 1 It also includes a temporary storage tank 5, and the bottom ends of multiple protective covers 46 are connected to the temporary storage tank 5 through hoses to collect the chemical liquid flowing out of the connection. The chemical liquid collected in the temporary storage tank 5 can be transferred to the chemical liquid recovery tank 3 and participate in the cycle again.

[0033] In one set of embodiments

[0034] Please see Figures 2-4 A double-ended lead screw 42 is rotatably mounted in a slide rail on the mounting frame 41. A drive motor connected to the double-ended lead screw 42 is installed in a housing at one end of the mounting frame 41 to drive the double-ended lead screw 42 to rotate. Two sets of slide blocks 43, slidably distributed at both ends of the slide rail, are threaded onto the double-ended lead screw 42 through threaded holes and threadedly connected to it. Meanwhile, elastic support members 44 on the two sets of connectors 45 are respectively installed on the two sets of slide blocks 43. The rotation of the double-ended lead screw 42 can control the two sets of slide blocks 43 to move closer or further apart, thereby completing the clamping of both ends of the pipe fitting. The connectors 45 are inserted into the ports at both ends of the pipe fitting, adapting to the clamping requirements of straight pipes of different lengths. Specifically:

[0035] The elastic support 44 includes a frame 441 fixed on the slide 43 and perpendicular to the mounting bracket 41, a movable seat 442 sliding on the frame 441, and a joint 45 fixed on the movable seat 442. Support springs 443 are connected between the upper and lower sides of the movable seat 442 and the upper and lower ends of the frame 441. The support springs 443 are used to achieve the elastic installation of the movable seat 442 on the frame 441. Furthermore, a vibration motor 47 is installed on each set of movable seats 442. The vibration force provided by the vibration motor 47 drives the movable seat 442 to slide back and forth on the frame 441, thereby achieving the technical effect of continuously vibrating the pipeline during polishing.

[0036] In one set of embodiments

[0037] Please see Figure 1 A turbidity sensor 7 (which needs to be calibrated periodically) is installed on the connector 45 connected to the chemical liquid recovery tank 3. This sensor is used to detect the turbidity of the chemical liquid flowing out of the pipe outlet, thereby determining the polishing process. Specifically, during chemical treatment (such as polishing and corrosion), the aluminum substrate reacts with the solution to generate suspended particles such as Al(OH)3 and Al2O3. The more vigorous the reaction (the faster the surface dissolution rate), the more significant the increase in turbidity. When the surface treatment is nearing completion (the reaction tends to stagnate), the rate of increase in turbidity will slow down significantly or even stabilize. Therefore, the turbidity change rate can be used as a preliminary indicator of whether the reaction is active, and is suitable for quickly determining whether the treatment has started or is nearing its end.

[0038] Meanwhile, a ring light 8 is fixedly fitted at the front end of the connector 45 connected to the chemical liquid storage tank 2 (the outer side of the ring light 8 lamp beads is covered with a frosted light-transmitting cover to avoid glare from direct strong light). At the same time, an image acquisition camera 9 is also installed on the lamp holder of the ring light 8 (the image acquisition camera 9 is equipped with an adjustable focus lens, which, together with the inner diameter of the pipe, ensures clear imaging). The turbidity sensor 7 is combined with the image acquisition to stop the circulation when the turbidity of the discharged chemical liquid detected by the turbidity sensor 7 tends to be stable, so that the chemical liquid in the pipe is emptied as much as possible. Then, the ring light 8 and the image acquisition camera 9 can be turned on to acquire images of the inner wall of the pipe for background analysis. The turbidity change reflects the reaction activity, realizing "dynamic process early warning"; the image acquisition can intuitively detect the inner wall state when the reaction stops, realizing "precise confirmation of the endpoint".

[0039] During use, this solution requires daily maintenance of each component according to the established maintenance plan to ensure its working condition.

[0040] It is worth noting that the specific models of the drive motor, vibration motor 47, turbidity sensor 7, ring light 8, and image acquisition camera 9 mentioned in this embodiment, as well as their matching power supply and control switch, can also be provided by the manufacturer. The circuits, electronic components, and modules involved are all existing technologies, which can be fully implemented by those skilled in the art, and there is no need to elaborate further.

[0042] Unless otherwise expressly specified and limited, the terms "set up," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.
