Description

Technical Field

[0001] This utility model relates to the field of filtration structure technology, specifically to a circulating filtration structure for an aluminum wire pickling tank. Background Technology

[0002] Aluminum wire pickling tanks are key equipment used for surface treatment in aluminum processing. Their main function is to remove oxide scale, oil, and impurities from the surface of the wire using an acidic solution, providing a clean substrate for subsequent processes such as electroplating, painting, or drawing.

[0003] Pickling solutions in pickling tanks are usually recycled. During the circulation process, the pickling solution is filtered. For example, in a double-layer pickling tank device with publication number CN221895132U, there are two layers, which are connected by a circulation pump pipeline and a drain channel to achieve circulation. A filter structure is set below the drain channel to filter the pickling solution. However, with long-term use, impurities in the pickling solution will gradually accumulate on the surface of the filter plate, causing the filter plate to become clogged and affecting the circulation efficiency of the pickling solution. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a circulating filtration structure for aluminum wire pickling tanks.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A circulating filtration structure for an aluminum wire pickling tank includes an installation mechanism installed on the pickling tank body. A first filter frame is provided on one side of the installation mechanism, and a second filter frame is slidably connected to the inner side of the first filter frame. A detection mechanism is provided at the bottom of the second filter frame for detecting the pressure generated when the second filter frame moves downward. The inner bottom wall of the second filter frame is equipped with a cleaning structure, and there are collection chambers on both sides of the inner bottom wall of the second filter frame, so that the cleaning structure can clean the deposited impurity particles into the collection chambers and play a role in preventing clogging.

[0006] Furthermore, the installation mechanism includes a first mounting plate installed on the pickling tank body, a second mounting plate fixedly connected to one side of the first mounting plate, and a first filter frame fixedly connected to the side of the second mounting plate away from the first mounting plate for positioning and support of the first filter frame.

[0007] Furthermore, the testing mechanism includes a sealing cylinder mounted on the first mounting plate, with a positioning rod slidably connected to the top of the sealing cylinder. The top of the positioning rod is inserted into the bottom of the storage compartment for supporting the storage compartment. The positioning rod is fixedly connected to a second elastic element at one end inside the sealing cylinder. A pressure sensor is connected to the bottom of the second elastic element to detect the downward pressure generated by the storage compartment and the second filter frame.

[0008] Furthermore, the cleaning structure includes a retractable cleaning section, one side of which is connected to a drive section, and the bottom of the cleaning section is slidably connected to the bottom wall inside the second filter frame, so that the drive section drives the cleaning section to slide and clean the surface on the bottom wall inside the second filter frame.

[0009] Furthermore, the cleaning unit includes a scraper, the top of which is inserted into the interior of a movable column. A first elastic member is fixedly connected inside the movable column, and the bottom of the first elastic member is fixedly connected to the top of the scraper, so that the first elastic member pushes the scraper to fit tightly against the inner bottom wall of the second filter frame.

[0010] Furthermore, one side of the first filter frame and the second mounting plate are provided with corresponding sliding grooves, and one side of the first mounting plate is provided with a positioning groove. One end of the moving column extends through the sliding grooves on the first filter frame and the second mounting plate into the positioning groove, and the outer side of the moving column is slidably connected with the corresponding sliding groove. A control rod is fixedly connected to one end of the movable column inside the positioning groove. One end of the control rod passes through the first mounting plate, and a drive structure is fixedly connected to the other end of the control rod outside the first mounting plate to drive the control rod to move the movable column back and forth.

[0011] Furthermore, a protective plate is fixedly connected inside the first filter frame, with the bottom of the protective plate located below the bottom of the chute.

[0012] Compared with existing technologies, this aluminum wire pickling tank circulating filtration structure has the following advantages: I. This utility model utilizes a first and a second filter frame that slide relative to each other, with a detection mechanism located below the second filter frame. A cleaning structure is provided on the bottom wall of the inner wall of the second filter frame, and a storage compartment is provided on the side. This is used to clean the bottom wall of the inner wall of the second filter frame during pickling solution circulation, removing impurities into the storage compartment to prevent filter pore blockage and ensure the flow of pickling solution. This solves the problem that impurities in existing pickling solutions gradually accumulate on the surface of the filter plate, causing blockage and affecting the efficiency of pickling solution circulation.

[0013] II. This utility model sets up storage compartments on both sides, and connects the storage compartments to the pressure sensor via positioning rods and a second elastic element, so as to determine whether the storage compartments are full while supporting them, and thus clean the storage compartments in a timely manner.

[0016] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0017] like Figure 1-5 As shown, this utility model provides a technical solution: a circulating filtration structure for an aluminum wire pickling tank, including an installation mechanism installed on the pickling tank body 1, a first filter frame 4 provided on one side of the installation mechanism, a second filter frame 5 slidably connected to the inner side of the first filter frame 4, a detection mechanism 7 provided at the bottom of the second filter frame 5 for detecting the pressure generated by the downward movement of the second filter frame 5; a cleaning structure 3 provided on the inner bottom wall of the second filter frame 5, and collection chambers 6 provided on both sides of the inner bottom wall of the second filter frame 5, so that the cleaning structure cleans the deposited impurity particles into the collection chambers 6, thereby preventing clogging.

[0018] In use, the first filter frame 4 has an open structure at both the top and bottom, and is rectangular in shape. At least two opposite sidewalls of the first filter frame 4 are provided with filter holes. The second filter frame 5 has an open top, its shape is adapted to the inner wall of the first filter frame 4, and it can slide up and down the inner wall of the first filter frame 4. The bottom wall of the second filter frame 5 is provided with filter holes, and at least two of the remaining sidewalls are also provided with several filter holes. The two bottom sidewalls of the second filter frame 5 are fixedly connected to the storage chamber 6, and the top of the storage chamber 6 has an opening communicating with the interior of the second filter frame 5. The cleaning structure 3 moves back and forth on the second filter frame 5, pushing impurity particles into the storage chamber 6, thus storing the impurities at the filter and preventing them from accumulating on the bottom wall inside the second filter frame 5, thereby preventing clogging.

[0019] Initially, the downward pressure generated by the second filter frame 5 is minimal, and this initial pressure value is recorded. Then, when drainage is initiated, the pickling solution circulates through the second filter frame 5, increasing the number of impurity particles intercepted. When these particles clog the second filter frame 5, it cannot properly allow the pickling solution to flow downwards, causing the second filter frame 5 to gradually move downwards and gradually increase the pressure on the detection mechanism 7. When this pressure reaches its maximum (and is equal to the pressure generated by the weight of a full storage bin 6), the cleaning structure 3 is activated, causing it to reciprocate inside the second filter frame 5. Impurities are swept into the collection chamber 6. When the collection chamber 6 is not full, the cleaning structure 3 restores the flow of the filter holes. When the liquid discharge stops, the pressure generated by the downward flow of liquid is lost, causing the second filter frame 5 to move upward. At the same time, the downward pressure on the second filter frame 5 decreases. When the collection chamber 6 is full, the weight of the collection chamber 6 prevents the second filter frame 5 from returning to its original position, and the pressure remains at its maximum. The staff then observes the status of the cleaning structure 3 or the warning light to determine that the second filter frame 5 still cannot return to its original position after filtration stops. Then, the cleaning structure 3 is turned off, and the filter structure is disassembled and cleaned.

[0020] The installation mechanism includes a first mounting plate 2 installed on the pickling tank body 1. A second mounting plate 10 is fixedly connected to one side of the first mounting plate 2. The side of the second mounting plate 10 away from the first mounting plate 2 is fixedly connected to the first filter frame 4 for positioning and support. In use, the pickling tank body 1 has a square opening. The second mounting plate 10 is adapted to the square opening, and the first mounting plate 2 is fixed to the outside of the opening of the pickling tank body 1 by screws. An annular sealing ring is provided on the side where the two are in contact for sealing, thereby fixing the filter structure. The first mounting plate 2 and the second mounting plate 10 are fixedly connected by screws, and the second mounting plate 10 is fixedly connected to the first filter frame 4 by screws. After installation, the top of the first filter frame 4 presses against the periphery of the drain channel hole, allowing the pickling liquid to enter the interior of the first filter frame 4 and then flow downward through the second filter frame 5, thus achieving the filtering function.

[0021] The detection mechanism 7 includes a sealing cylinder 701 mounted on the first mounting plate 2. A positioning rod 703 is slidably connected to the top of the sealing cylinder 701. The top of the positioning rod 703 is inserted into the bottom of the storage compartment 6 to support the storage compartment 6. A second elastic element 704 is fixedly connected to one end of the positioning rod 703 inside the sealing cylinder 701. A pressure sensor 705 is connected to the bottom of the second elastic element 704 to detect the downward pressure generated by the storage compartment 6 and the second filter frame 5. In use, a sealing structure, such as a sealing ring, is provided between the sealing cylinder 701 and the positioning rod 703 to ensure the sealing effect between the positioning rod 703 and the sealing cylinder 701. When the second filter frame 5 and the storage compartment 6 exert downward pressure, the positioning rod 703 presses the second elastic element 704 downward, causing the spring of the second elastic element 704 to press against the top of the pressure sensor 705. The pressure sensor 705 is installed inside the sealing cylinder 701 to detect the downward pressure. At the same time, the sealing cylinder 701 is fixedly connected to the first mounting plate 2 by the support rod 702. The support rod 702 is hollow inside, which facilitates the installation of wiring inside. The sealing cylinder 701 and the first mounting plate 2 are connected by corresponding connection terminals. Alternatively, a wireless connection can be used to output the data detected by the pressure sensor 705.

[0022] The cleaning structure 3 includes a retractable cleaning section. A drive section is connected to one side of the cleaning section, and the bottom of the cleaning section is slidably connected to the bottom wall inside the second filter frame 5, so that the drive section drives the cleaning section to slide and clean the surface on the bottom wall inside the second filter frame 5. The cleaning section includes a scraper 301. The top of the scraper 301 is inserted into the interior of the moving column 303. A first elastic member 302 is fixedly connected inside the moving column 303. The bottom of the first elastic member 302 is fixedly connected to the top of the scraper 301, so that the first elastic member 302 pushes the scraper 301 to fit tightly against the bottom wall inside the second filter frame 5.

[0023] In use, the first elastic element 302 is a spring, and the scraper 301 is L-shaped. The moving column 303 has a sealing ring inside and is slidably connected to the part into which the scraper 301 is inserted, which has a sealing effect and protects the spring. The spring force is adapted to the weight of the scraper 301 and the resistance of the second filter frame 5 sliding downward, so as to avoid the second filter frame 5 moving downward due to excessive spring force. This allows the first elastic element 302 to provide the power for the scraper 301 to follow the second filter frame 5 downward, so as to ensure that the scraper 301 and the second filter frame 5 are in contact. Alternatively, a horizontal bar can be provided above the horizontal part of the L-shaped scraper 301 to limit the scraper 301 from detaching from the second filter frame 5 and improve the cleaning effect.

[0024] The first filter frame 4 and the second mounting plate 10 are each provided with a corresponding sliding groove on one side, and the first mounting plate 2 is provided with a positioning groove 9 on one side. One end of the moving column 303 extends through the sliding groove on the first filter frame 4 and the second mounting plate 10 into the positioning groove 9, and the outer side of the moving column 303 is slidably connected to the corresponding sliding groove. A control rod 304 is fixedly connected to one end of the moving column 303 located inside the positioning groove 9. One end of the control rod 304 extends through the first mounting plate 2, and a drive structure is fixedly connected to the other end of the control rod 304 located outside the first mounting plate 2, for driving the control rod 304 to drive the moving column 303 to slide back and forth.

[0025] During use, a sealing ring is provided between the control rod 304 and the first mounting plate 2 to achieve a sealing effect. At the same time, the drive structure can be an electric telescopic push rod. The electric telescopic push rod pushes the control rod 304 to reciprocate. The control rod 304 drives the scraper 301 to move through the moving column 303, so that the scraper 301 pushes the impurity particles on the second filter frame 5 into the collection chamber 6, which plays a role in preventing blockage and cleaning.

[0026] A protective plate 8 is fixedly connected inside the first filter frame 4. The bottom of the protective plate 8 is located below the bottom of the slide groove. In use, the protective plate 8 is L-shaped and contacts the first filter frame 4 and the second filter frame 5 respectively. It is fixedly connected to the first filter frame 4 with screws. The protective plate 8 is used to shield the slide groove and play a protective role.
