Description

A liquid aluminum filtration device Technical Field

[0001] This utility model belongs to the field of aluminum liquid filtration technology, and in particular relates to an aluminum liquid filtration device. Background Technology

[0002] According to the published patent CN218553288U, an aluminum liquid filtration device includes a solid filter box. The upper surface of the filter box has a first groove and a second groove, each with an opening at its lower end. Each opening contains a filter plate for filtering aluminum liquid. The lower part of the first and second grooves has an aluminum liquid flow channel connecting the two grooves via the opening. After the device is completed, the cooperation of the two filter plates and the filter plate built into the pressure block allows for repeated filtration of the aluminum liquid in the filter box, greatly improving the filtration effect. However, it still has the following shortcomings:

[0003] After the above equipment is completed, it only filters the aluminum liquid multiple times. However, the flow rate of the aluminum liquid cannot be changed during filtration, which makes the flow rate of the aluminum liquid slow down, thus reducing the filtration efficiency of the aluminum liquid. Therefore, we propose an aluminum liquid filtration device. Summary of the Invention

[0004] The purpose of this invention is to provide an aluminum liquid filtration device that solves the problem of reduced filtration efficiency caused by simply filtering the aluminum liquid multiple times without changing its flow rate during filtration.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is an aluminum liquid filtration device, including a filter box, an outlet pipe fixedly connected to the inner wall of the filter box, a butterfly valve rotatably connected to the inner wall of the outlet pipe, an inlet pipe fixedly connected to the top inner wall of the outlet pipe, and a filtration mechanism provided on the outer wall of the filter box.

[0007] The filtration mechanism includes an L-plate, the outer wall of which is fixedly connected to the outer wall of the filter box. A first motor is fixedly connected to the inner wall of the L-plate. A worm gear is fixedly connected to the bottom output end of the first motor via a coupling. A disc is fixedly connected to the outer wall of the worm gear on the side away from the first motor. A fixed rod is fixedly connected to the outer wall of the disc on the side away from the worm gear. A connecting rod is rotatably connected to the outer wall of the fixed rod. A rotating shaft is rotatably connected to the inner wall of the connecting rod. A U-shaped plate is fixedly connected to the outer wall of the rotating shaft. A slide rail is fixedly connected to the outer wall of the filter box at the end near the U-shaped plate.

[0008] Furthermore, the inner wall of the slide rail is slidably connected to the outer wall of the U-shaped plate, a square groove is provided on the top inner wall of the filter box, the outer wall of the U-shaped plate is slidably connected to the inner wall of the square groove, a filter plate is fixedly connected to the outer wall of the U-shaped plate, and a cleaning mechanism is provided on the outer wall of the filter box.

[0009] Furthermore, the cleaning mechanism includes a mounting frame, the outer wall of which is fixedly connected to the outer wall of the filter box, and a roller is rotatably connected to the inner wall of the mounting frame. A worm gear is fixedly connected to the outer wall of the roller on the side near the first motor, and the outer wall of the worm gear meshes with the outer wall of the worm.

[0010] Furthermore, a crown gear is fixedly connected to the outer wall of the roller on the side away from the first motor, and a mounting plate is fixedly connected to the top outer wall of the filter box. A rotating rod is rotatably connected to the inner wall of the mounting plate, and a gear is fixedly connected to the outer wall of the rotating rod on the side near the first motor. The outer wall of the gear meshes with the outer wall of the crown gear.

[0011] Furthermore, a second disc is fixedly connected to the outer wall of the rotating rod on the side away from the gear, a round rod is fixedly connected to the outer wall of the second disc, a connecting frame is slidably connected to the outer wall of the round rod, and a sliding groove is provided on the top inner wall of the filter box.

[0012] Furthermore, a square plate is slidably connected to the inner wall of the chute, and the outer wall of the square plate is fixedly connected to the outer wall of the connecting frame.

[0013] Furthermore, a baffle is slidably connected to the inner wall of the second square groove, and a support plate is fixedly connected to the bottom outer wall of the square plate. The inner wall of the support plate is provided with several circular grooves.

[0014] Furthermore, a sliding rod is slidably connected to the inner wall of the circular groove, a spring is sleeved on the outer wall of the sliding rod, and a scraper is fixedly connected to the outer wall of the sliding rod near the filter plate.

[0015] This utility model has the following beneficial effects:

[0016] 1. This utility model incorporates a fixed rod and a filter plate. When the disc rotates, the fixed rod moves in a circular motion, which in turn moves the connecting rod in an arc shape. The connecting rod then moves the rotating shaft, which in turn moves the U-shaped plate back and forth. Simultaneously, the U-shaped plate slides within the slide rail and square groove. As the U-shaped plate moves, it also moves the filter plate, thereby improving filtration efficiency. The up-and-down movement of the filter plate alters the flow rate of the molten aluminum, preventing the molten aluminum from flowing too slowly within the equipment and thus reducing filtration efficiency.

[0017] 2. This utility model incorporates a spring and a scraper. When the square plate moves, it moves the support plate, which in turn moves the sliding rod. Simultaneously, the scraper moves with the sliding rod. As the scraper moves, it pushes impurities on the filter plate to both sides, preventing impurities from accumulating on the filter plate. When the filter plate descends, the spring compresses the scraper, thus improving filtration stability. The back-and-forth movement of the scraper effectively cleans impurities from the filter plate, preventing them from clogging the filter plate and rendering it unusable.

[0018] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0030] Please refer to Figures 1-7. This utility model is an aluminum liquid filtration device, including a filter box 1. A discharge pipe 101 is fixedly connected to the inner wall of the filter box 1. A butterfly valve 102 is rotatably connected to the inner wall of the discharge pipe 101. Rotating the butterfly valve 102 allows the operator to control the discharge of aluminum liquid. An inlet pipe 103 is fixedly connected to the top inner wall of the discharge pipe 101. A filtration mechanism 2 is provided on the outer wall of the filter box 1. The filtration mechanism 2 includes an L-plate 201. The outer wall of the L-plate 201 is fixedly connected to the outer wall of the filter box 1. A first... Motor 202: When the operator starts the first motor 202, a worm gear 203 is fixedly connected to its bottom output end via a coupling. A disc 204 is fixedly connected to the outer wall of the worm gear 203 on the side away from the first motor 202. A fixed rod 205 is fixedly connected to the outer wall of the disc 204 on the side away from the worm gear 203. After the first motor 202 starts, it will rotate the worm gear 203, which in turn will rotate the disc 204. As the disc 204 rotates, it will cause the fixed rod 205 to move in a circular motion, thus realizing the transfer of kinetic energy between the parts. A connecting rod 206 is rotatably connected to the outer wall of the fixed rod 205. A rotating shaft 207 is rotatably connected to the inner wall of the connecting rod 206. A U-shaped plate 208 is fixedly connected to the outer wall of the rotating shaft 207. When the fixed rod 205 moves, it will cause the connecting rod 206 to move in an arc. Then, the connecting rod 206 will cause the rotating shaft 207 to move. When the rotating shaft 207 moves, it will cause the U-shaped plate 208 to move, thus realizing the kinetic energy transfer between the parts. A slide rail 209 is fixedly connected to the outer wall of the filter box 1 near the U-shaped plate 208. The inner wall of the slide rail 209 is flush with the outer wall of the U-shaped plate 208. The filter box 1 is slidably connected to the wall. A square groove 210 is provided on the inner wall of the top of the filter box 1. When the U-shaped plate 208 slides in the slide rail 209, the U-shaped plate 208 will not swing left and right, so that the U-shaped plate 208 keeps moving horizontally. The outer wall of the U-shaped plate 208 is slidably connected to the inner wall of the square groove 210. A filter plate 211 is fixedly connected to the outer wall of the U-shaped plate 208. A cleaning mechanism 3 is provided on the outer wall of the filter box 1. When the U-shaped plate 208 moves, it will move the filter plate 211 with it. When the filter plate 211 moves, it will filter the aluminum liquid to prevent impurities from being contained in the aluminum liquid.

[0031] The cleaning mechanism 3 includes a mounting frame 301. The outer wall of the mounting frame 301 is fixedly connected to the outer wall of the filter box 1. A roller 302 is rotatably connected to the inner wall of the mounting frame 301. When the roller 302 rotates in the mounting frame 301, the roller 302 will not wobble, ensuring smooth operation. A worm gear 303 is fixedly connected to the outer wall of the roller 302 near the first motor 202. The outer wall of the worm gear 303 meshes with the outer wall of the worm 203. When the worm 203 rotates, it drives the worm gear 303 to rotate, and then the worm gear 303 drives the roller 302 to rotate, completing the kinetic energy transfer process between the parts. A crown is fixedly connected to the outer wall of the roller 302 away from the first motor 202. Gear 304, a mounting plate 305 is fixedly connected to the top outer wall of the filter box 1, and a rotating rod 306 is rotatably connected to the inner wall of the mounting plate 305. When the rotating rod 306 rotates in the mounting plate 305, the rotating rod 306 will maintain stable operation to prevent the rotating rod 306 from shaking. A gear 307 is fixedly connected to the outer wall of the rotating rod 306 near the first motor 202. The outer wall of the gear 307 meshes with the outer wall of the crown gear 304. When the roller 302 rotates, it will drive the crown gear 304 to rotate. Then the crown gear 304 will drive the gear 307 to rotate. At the same time, the rotating rod 306 will rotate with the gear 307. When one part moves, other parts will also move.

[0032] A disc 310 is fixedly connected to the outer wall of the rotating rod 306 away from the gear 307. A round rod 308 is fixedly connected to the outer wall of the disc 310. A connecting frame 309 is slidably connected to the outer wall of the round rod 308. When the rotating rod 306 rotates, it will move the disc 310. Then, the disc 310 will move the round rod 308 in a circular motion. At the same time, the round rod 308 will slide in the connecting frame 309, realizing the kinetic energy transfer process between the parts. A groove 311 is opened on the inner wall of the top of the filter box 1. A square plate 312 is slidably connected to the inner wall of the groove 311. When the square plate 312 slides in the groove 311, the square plate 312 will not wobble from side to side, keeping the square plate 312 moving horizontally. The outer wall of the square plate 312 is fixedly connected to the outer wall of the connecting frame 309. Several discharge ports 313 are opened on the inner wall of the filter box 1. The inner wall of the filter box 1 has several square grooves 314. A baffle 320 is slidably connected to the inner wall of the square groove 314 to block the discharge port 313 and prevent leakage during aluminum molten filtration. A support plate 315 is fixedly connected to the bottom outer wall of the square plate 312. A number of circular grooves 316 are opened on the inner wall of the support plate 315. When the sliding rod 317 slides in the circular groove 316, the sliding rod 317 will not wobble from side to side, so that the sliding rod 317 keeps a straight line. The sliding rod 317 is slidably connected to the inner wall of the circular groove 316. A spring 318 is sleeved on the outer wall of the sliding rod 317. A scraper 319 is fixedly connected to the outer wall of the sliding rod 317 near the filter plate 211. When the scraper 319 moves, it will clean the filter plate 211 to prevent excessive impurities from accumulating on the filter plate 211.

[0033] One specific application of this embodiment is:

[0034] When the equipment is needed, the molten aluminum is first poured into the filter box 1 through the feed pipe 103. After pouring, the first motor 202 is started. The first motor 202 rotates the worm gear 203, which in turn rotates the disc 204. As the disc 204 rotates, it causes the fixed rod 205 to move in a circular motion. The fixed rod 205 then moves the connecting rod 206 in an arc shape. The connecting rod 206 then moves the rotating shaft 207. The rotating shaft 207 then moves the U-shaped plate 208 back and forth, while the U-shaped plate 208 slides between the slide rail 209 and the square groove 210. Then, when the U-shaped plate 208 moves, it will move the filter plate 211 along with it. The movement of the filter plate 211 will cause the molten aluminum to move, and the filtration efficiency will be increased through the movement of the filter plate 211 and the molten aluminum. The molten aluminum will then flow to the bottom of the filter box 1, while impurities will remain on the filter plate 211. Simultaneously, when the worm gear 203 rotates, it will cause the worm wheel 303 to rotate. The worm wheel 303 will then cause the roller 302 to rotate. The roller 302 will then cause the crown gear 304 to rotate. When the crown gear 304 rotates, the gear 307 will rotate along with it. The gear 307 will then cause the rotating rod 306 to rotate. When the filter rotates, it carries the second disc 310, which in turn carries the round rod 308 in a circular motion. As the round rod 308 moves, it slides within the connecting frame 309, simultaneously pressing against the connecting frame 309, causing it to move back and forth. This movement of the connecting frame 309 carries the square plate 312, which slides within the groove 311. The square plate 312's movement carries the support plate 315, which in turn carries the sliding rod 317. Simultaneously, the scraper 319 moves along with the sliding rod 317, pushing impurities on the filter plate 211 to both sides. To prevent impurities from accumulating on the filter plate 211, the spring 318 will squeeze the scraper 319 when the filter plate 211 descends, causing the scraper 319 to move. As the scraper 319 moves, it will move the sliding rod 317, ensuring that the scraper 319 always adheres to the filter plate 211. After filtration, the baffle 320 can be pulled out from the square groove 314. After being pulled out, the impurities on the filter plate 211 will be pushed out from the impurity discharge port 313 by the scraper 319, preventing impurities from staying in the filter box 1 for a long time. Then, the butterfly valve 102 can be turned. After the butterfly valve 102 is turned, the filtered aluminum liquid will be discharged from the discharge pipe 101.
