Description

Technical Field

[0001] This utility model relates to the field of waste liquid recycling and purification technology, specifically a device for recycling and purifying waste liquid tested by a laser particle size analyzer. Background Technology

[0002] In the powder metallurgy industry, frequent sampling and control of powder particle size are crucial for the mass production of pre-alloyed powders with iron, nickel, and cobalt as the main components. Current technology widely uses laser particle size analyzers to test samples. The specific procedure involves taking a small amount of the pre-alloyed powder sample, diluting it with purified water and dodecane in a measuring cup, dispersing it ultrasonically for a few minutes, and then adding it to the circulating sampling system of the laser particle size analyzer for computer scanning and testing. The waste liquid from the laser particle size analyzer, containing the pre-alloyed powder, is then directly discharged into the sewer system. Over time, this causes environmental pollution and wastes valuable metal resources.

[0003] Currently, existing laser particle size analyzer test waste liquid recovery and purification devices typically involve multiple steps to purify and recover the test waste liquid. During solid-liquid separation, existing test waste liquid solid-liquid separation methods mostly use filtration structures. However, during the waste liquid recovery process, particulate matter easily clogs the filter media, leading to decreased filtration efficiency, frequent cleaning, and affecting the waste liquid recovery and purification effect. There is a problem that the filter structure is easily clogged. Furthermore, during use, after the test waste liquid particles are filtered, they are stored on the filter structure. After the test waste liquid is purified, the internal cleaning of the recovery and purification device is required, but the filtered particles are not easy to collect and remove, resulting in a problem that the particles on the filter structure are not easy to remove.

[0018] Please refer to Figure 3. A diverter plate 5 is fixedly connected to the lower part of the water inlet pipe 3. A servo motor 6 is fixedly connected to the lower part of the diverter plate 5. A connecting rod 17 is keyed to the lower output shaft of the servo motor 6. The connecting rods 17 are arranged in a ring array with respect to the output shaft of the servo motor 6.

[0019] Specifically, the flow divider 5 is conical and is located above the first filter plate 7. A connecting pipe is provided on one side of the servo motor 6. The connecting pipe transmits the wires of the servo motor 6 out of the housing 1. The servo motor 6 is controlled and started through the wires. The inner side of the connecting rod 17 is in contact with the first filter plate 7 and the second filter plate 13.

[0020] Please see Figure 3 A movable rod 16 is fixedly connected to one side of the connecting rod 17. The ends of the movable rod 16 and the push rod 15 are in contact with the outer shell 1, and the movable rod 16 is located above the push rod 15.

[0021] Specifically, the movable rod 16 is located at the connection between the first filter plate 7 and the second filter plate 13, and there is a gap between the movable rod 16 and the push rod 15.

[0022] Please refer to Figure 3 to Figure 4 A collection port 12 is provided on one side of the support plate 14, and a movable plate 8 is provided inside the collection port 12. The movable plate 8 fits closely with the inside of the collection box 9.

[0023] Specifically, the support plate 14 is annular, the collection port 12 is arc-shaped, a lip-shaped sealing ring is provided on the outer side of the movable plate 8, a sealing groove is provided on the edge of the movable plate 8, and the sealing ring fits into the collection port 12.

[0024] Please refer to Figure 1 to Figure 5 A cleaning port 18 is provided on one side of the outer casing 1. A baffle 2 is provided inside the cleaning port 18. A buckle 4 is fixedly connected to one side of the outer casing 1. One side of the buckle 4 is connected to the upper part of the baffle 2.

[0025] Specifically, the edge of the baffle 2 is provided with a sealing ring, which fits into the cleaning port 18. The electric telescopic rod 10 is connected to the external control structure through a wire, and a sealing structure is provided at the upper part of the connection between the electric telescopic rod 10 and the collection box 9.

[0026] Please refer to Figure 1 to Figure 5 The buckle 4 consists of a rod, a stop block and a support spring. One side of the collection box 9 is connected to the water outlet pipe 11, and the water outlet pipe 11 corresponds to the second filter plate 13.

[0027] Specifically, the insert rod of the buckle 4 passes through the upper part of the baffle 2, the outer side of the stop block is chamfered, and a supporting spring is provided between the stop block and the insert rod.

[0028] During use, the waste liquid conveying pipe transports the waste liquid to the inlet pipe 3, and then disperses it to the edge through the conical diverter plate 5. The waste liquid drips onto the first filter plate 7, and the water in the waste liquid leaks out through the holes of the first filter plate 7. The filtered particles fall onto the support plate 14, and then are filtered again by the second filter plate 13 on one side. The arrangement of the first filter plate 7 and the second filter plate 13 increases the filtration leakage area. During filtration, the servo motor 6 is activated, driving the connecting rod 17 to rotate. The connecting rod 17 connects the first filter plate 7 and the second filter plate 14. The surface of plate 13 is scraped to separate particles from the filter structure and cause them to fall to the edge, preventing particle blockage. The movable rod 16 agitates the particles, allowing water to permeate through and then filter through the second filter plate 13. The filtered water is collected through the upper funnel of the outlet pipe 11 and then transferred to the receiving pipe. Through the coordinated arrangement of the servo motor 6, connecting rod 17, and movable rod 16, the surface of the filter structure can be cleaned and scraped during use, thereby increasing the waste liquid filtration effect and reducing the clogging of the filter structure.

[0029] After filtration, the electric telescopic rod 10 is activated, pulling the movable plate 8 downwards until it is below the inside of the collection box 9. The movable plate 8 moves, exposing the collection port 12, allowing particles on the support plate 14 to fall into the collection box 9 through the collection port 12. The setup of the electric telescopic rod 10, collection box 9, movable plate 8, and collection port 12 effectively collects particles. The servo motor 6 is activated, driving the push rod 15 via the connecting rod 17 to push the particles on the support plate 14 to the collection port 12. The connecting rod 17 and push rod 15 further push the particles on the support plate 14, separating the baffle 2 from the buckle 4 and removing the baffle 2. The particles on the movable plate 8 are then cleaned through the cleaning port 18. After cleaning, the movable plate 8 is moved back to its original position, and the remaining particles inside the collection box 9 are cleaned. The coordinated setup of the baffle 2, cleaning port 18, and buckle 4 allows for easy cleaning of particles within the collection box 9 during use, achieving the goal of convenient particle removal in the filtration structure.
