Description

Technical Field

[0001] This invention relates to the field of electroplating technology, specifically to an electroplating wastewater evaporation and crystallization device. Background Technology

[0002] Electroplating is the process of depositing a thin layer of other metals or alloys onto the surface of certain metals using the principle of electrolysis. It is a process that uses electrolysis to attach a metal film to the surface of metal or other material parts. After electroplating, the surface needs to be cleaned to remove impurities and liquids, and the wastewater is collected through a collection device.

[0003] Conventional electroplating wastewater collection devices collect and process the wastewater, but they still have certain drawbacks:

[0004] First, in wastewater treatment, substances that cannot be cleaned by chemical additives can be removed by evaporation and crystallization. These substances are precipitated out through the evaporation and crystallization process, but the internal temperature needs to be continuously increased during evaporation, which is quite energy-intensive.

[0005] Secondly, the wastewater after rinsing will be collected and then chemically treated to render it harmless before being discharged to a designated discharge point into a river or directly reused for cleaning. Both methods have low wastewater utilization rates.

[0006] Third, the internal crystals will gradually increase in volume during the continuous evaporation process, which can easily affect the operation of the instrument. At the same time, the overall instrument is not easy to maintain, the various values ​​inside the instrument are not clear enough for quick confirmation, and the automation is low.

At the same time, the inner wall is scraped to prevent the crystals from being fixed on the inner wall of the spiral plate 22 area. By collecting the crystals, the crystals are further crushed to reduce the size of the gaps between the crystals and increase the storage capacity. The liquid evaporates to form steam, which enters the cooling pipe 11 to cool and turn back into liquid, which enters the water tank 31. Then, the steam is turned back into steam by the steam generator on the steam pipe 12 and sent back into the evaporation tank 1 to heat the inner tank 21, saving energy.

[0039] The evaporation mechanism 2 also includes a connecting groove 212, a rotating shaft 213, an elastic spring 214, and a lifting groove 215. The connecting groove 212 is opened on the inner barrel 21, and the rotating shaft 213 is rotatably installed inside the connecting groove 212. The elastic spring 214 is installed in the connecting groove 212, one end of the elastic spring 214 is fixedly connected to the rotating shaft 213, and the other end of the elastic spring 214 is fixedly connected to the lower end of the rotating gear 210.

[0040] The evaporation mechanism 2 also includes a filter hole 216 and a replacement tank 219; the filter hole 216 is opened through the lower end of the exhaust shaft 25, and the replacement tank 219 is threaded on the lower end of the evaporation tank 1 and is sleeved on the crushing shaft 218.

[0041] This embodiment refers to Figure 1-3 An exhaust shaft 25 is provided, which is connected to a lifting groove 215 on the inner wall of the inner barrel 21. A servo motor 27 drives a rotating gear 4 211 to rotate, which in turn drives a rotating gear 3 210 to rotate, causing the exhaust shaft 25 to rotate along the lifting groove and move up and down, thereby moving the crushing rod 218 up and down. This agitates the crystallization activity in the replacement barrel 219, better crushing the internal crystals and further crushing the crystals at the bottom. The rebound force of the elastic spring 214 generates a stronger impact force to crush the crystals, preventing the crushing shaft from being restricted when there are too many internal crystals, and further optimizing the internal space capacity. At the same time, another servo motor drives a telescopic rod 28 and a rotating gear 29 to rotate, which in turn drives a rotating gear 1 26 to rotate, causing the spiral plate 22 to rotate and stir the liquid. The rotation of the spiral plate 22 also drives the scraper 24 to rotate and scrape off the crystals attached to the inner wall of the inner barrel 21. A display screen 14 is provided on the evaporation barrel 1. The display screen 14 is connected to multiple sensors in the water tank 31 to monitor relevant data for easy adjustment.

[0042] The filter mechanism 3 also includes a chute 33 and a filter frame 34; the chute 33 is arrayed on the inner wall of the inner box 32, the filter frame 34 is arrayed inside the inner box 32, the filter frame 34 is slidably connected to the chute 33, and a drain hole is provided at the lower end of the inner box 32.

[0043] This embodiment refers to Figure 4-5 The system is equipped with a water tank 31, and an inner tank 32 is set inside the water tank 31. Multiple grooves 33 are arrayed on the inner wall of the inner tank 32. A filter frame 34 is slidably set inside the grooves 33. Filter materials of different materials are set inside the filter frame 34 to filter the liquid and remove impurities.

[0044] In use, the liquid in the inner tank 21 is heated and evaporated by the heating rod 217. The steam enters the cooling pipe 11 through the exhaust shaft 25, condenses into droplets, and falls into the inner tank 32. After passing through the filter rack 34 in the inner tank 32 and removing internal impurities through various filter materials, it enters the water tank 31. The liquid is converted back into steam by the steam generator on the steam pipe 12 on one side of the water tank 31 and sent back to the evaporation tank 1 to provide auxiliary heating for the inner tank 21. The display screen 14 automatically adjusts the power of the heating rod 217 based on the data sensors installed in the evaporation tank 1 and the inner tank 21 to reduce energy consumption. The liquid converted back into steam after the steam in the evaporation tank 1 is cooled is sent back to the water tank 31 by the pump on the return pipe 13 at the lower end of the evaporation tank 1.

[0045] During evaporation, a servo motor 27 drives a second rotating gear 29 to rotate. The rotation of the second rotating gear 29 drives a first rotating gear 26 to rotate, causing the spiral plate 22 to rotate. The rotation of the spiral plate 22, in conjunction with the internal inclined plate 23, agitates the liquid, achieving better internal thermal equilibrium and crystallization. Simultaneously, the rotation of the spiral plate 22 drives a scraper 24 to rotate, scraping off any crystals that may be attached to the inner wall of the spiral plate 22 area. The scraped-off crystals, along with other crystals, enter the replacement tank 219. Another servo motor 27 drives a fourth rotating gear 211 to rotate, and the rotation of the fourth rotating gear 211... The rotation of the rotating gear 210 causes the exhaust shaft 25 to rotate and move up and down along the lifting groove 215, while driving the crushing shaft 218 to rotate and crush the crystals to reduce their volume. At the same time, it presses down and squeezes the internal crystals to further crush them and increase the internal storage capacity. The replacement bucket 219 can be disassembled by rotation. While the exhaust shaft 25 moves up and down, the rotating gear 3 210 moves up and down along the rotating gear 4 211, while driving the rotating gear 29 and the telescopic rod 28 to move up and down. At the same time, the elastic spring 214 in the connecting groove causes the exhaust shaft 25 to rotate to the top and quickly spring back to its original position along the lifting groove 215.

[0046] The inner box 32 is equipped with a sliding groove 33, which allows for quick disassembly and installation of the filter frame 34, facilitating the replacement of the filter material inside the filter frame 34.
