Description

Technical Field

[0001] This utility model relates to the field of electroplating waste liquid treatment technology, and in particular to a waste liquid collection mechanism. Background Technology

[0002] Wastewater and waste liquid discharged from electroplating plants contain large amounts of metal ions such as chromium, cadmium, and nickel, as well as cyanide, acids, and alkalis. They often contain organic additives. The composition of wastewater generated in electroplating production is very complex. In addition to cyanide (CN-) and acids and alkalis, heavy metals are a potentially extremely hazardous category of wastewater from the electroplating industry. These substances seriously endanger the environment and human health.

[0003] A patented electroplating waste liquid collection and treatment transfer device (publication number CN210193496U) uses a feeding hopper to add a precipitant to the storage tank. Through a chemical reaction, the pH value of the electroplating waste liquid is neutralized. At the same time, the metal ions in the electroplating waste liquid combine with hydroxide ions to form solids that precipitate to the bottom of the storage tank. This reduces the workload of subsequent wastewater treatment steps, improves the purification efficiency of subsequent treatment, and reduces production costs.

[0004] In their daily work, the inventors discovered that the above-mentioned electroplating waste liquid collection and treatment transfer device had a poor solid-liquid separation effect because its storage tank contained a mixture of solid impurities and waste liquid. Utility Model Content

[0005] The purpose of this utility model is to solve the technical problems mentioned above, and to propose a waste liquid collection mechanism for electroplating.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a waste liquid collection mechanism for electroplating treatment, comprising a filter box, a discharge pipe fixedly installed on one side surface of the filter box, a valve fixedly installed on the outer wall surface of the discharge pipe, a lifting device provided on the side of the filter box, the lifting device comprising two L-shaped rods, the two L-shaped rods being symmetrically fixedly installed on the side of the filter box, a sliding plate being slidably connected to the surface of each of the two L-shaped rods, a stirring box being fixedly installed between the two sliding plates, a filter screen being fixedly installed inside the filter box, a partition being slidably connected to the inner wall of the stirring box, and a feed inlet being fixedly installed on the top surface of the stirring box. The filter screen effectively filters out fixed impurities in the waste liquid.

[0007] Preferably, a U-shaped bracket is fixedly installed on the side of the filter box, and a threaded rod is rotatably connected between the inner walls of both ends of the U-shaped bracket. A motor is fixedly installed on the top surface of the U-shaped bracket, and the output end of the motor is fixedly connected to the threaded rod. The motor drives the threaded rod to rotate.

[0008] Preferably, the inner wall surface of the U-shaped bracket has a through groove, and a vertical rod is fixedly installed between the inner walls of the two ends of the through groove. A movable plate is threadedly connected to the surface of the threaded rod, and the side of the movable plate is fixedly connected to the mixing tank. The threaded rod enables the movable plate to move on the surface of the vertical rod, and the movable plate enables the mixing tank to move.

[0009] Preferably, a stirring device is provided between the inner walls of the two sides of the mixing tank. The stirring device includes a rotating rod rotatably connected between the inner walls of the two sides of the mixing tank, and multiple stirring blades are fixedly installed on the outer surface of the rotating rod. The stirring blades effectively mix and stir the electroplating waste liquid and the precipitant.

[0010] Preferably, the side of the mixing tank has a groove, a slide plate is slidably connected inside the groove, a rack is fixedly installed on the surface of the slide plate, and a gear is fixedly installed on the outer wall surface of the rotating rod. The rack and the gear mesh with each other. The gear drives the rotating rod to rotate, and the rack drives the gear to rotate.

[0011] Preferably, the side of the mixing tank has a strip-shaped groove, and a displacement plate is slidably connected inside the strip-shaped groove. A connecting rod is fixedly installed between the displacement plate and the sliding plate. A support plate is fixedly installed on the side of the mixing tank, and an electric telescopic rod is fixedly installed on the surface of the support plate. The output end of the electric telescopic rod is fixedly connected to the displacement plate. The electric telescopic rod enables the displacement plate to move inside the strip-shaped groove, and the connecting rod enables the sliding plate to move inside the groove.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0013] 1. In this utility model, by setting up a lifting device, when the device is needed, firstly, waste liquid and precipitant are introduced into the interior of the mixing tank through the feed inlet. The motor is started, and the motor drives the threaded rod to rotate. The rotation of the threaded rod drives the movable plate to move on the surface of the upright. The movement of the movable plate on the surface of the upright drives the mixing tank to move downward. The downward movement of the mixing tank drives the sliding plate to move downward on the surface of the L-shaped rod. At the same time, when the mixing tank moves downward into the interior of the filter tank, the motor is turned off, and then the partition is pulled to remove the partition from the interior of the mixing tank. At this time, the waste liquid will fall into the interior of the filter tank, and then the filter screen will filter the waste liquid, removing impurities from the waste liquid. Through the cooperation of the above structure, the filter screen can separate solid impurities and electroplating waste liquid in the mixture, better removing solid impurities from the tank and improving the quality of solid-liquid separation.

[0014] 2. In this utility model, by setting up a stirring device, when it is necessary to accelerate the reaction between waste liquid and precipitant, the electric telescopic rod is first activated. The activation of the electric telescopic rod drives the displacement plate to move inside the strip groove. The movement of the displacement plate inside the strip groove drives the connecting rod to move. The movement of the connecting rod drives the sliding plate to move inside the groove. The movement of the sliding plate inside the groove drives the rack to move. The movement of the rack meshes with the gear, thereby causing the gear to rotate. The rotation of the gear drives the rotating rod to rotate. The rotation of the rotating rod drives the stirring fan blade to rotate. The rotation of the stirring fan blade enables the precipitant and electroplating waste liquid to be efficiently mixed and stirred. Through the cooperation of the above structure, the stirring fan blade can efficiently mix and stir the precipitant and electroplating waste liquid, thereby improving the purification efficiency of subsequent treatment.

Multiple stirring blades 502 are fixedly installed on the outer wall surface of the rotating rod 501. When it is necessary to accelerate the reaction between waste liquid and precipitant, the electric telescopic rod 511 is activated first. The activation of the electric telescopic rod 511 drives the displacement plate 508 to move inside the strip groove 507. The movement of the displacement plate 508 inside the strip groove 507 drives the connecting rod 509 to move. The movement of the connecting rod 509 drives the sliding plate 504 to move inside the groove 503. The movement of the sliding plate 504 inside the groove 503 drives the rack 505 to move.

Then the partition 405 is pulled to remove the partition 405 from the inside of the mixing tank 403. At this time, the waste liquid will fall into the inside of the filter tank 1. Then the filter screen 404 will filter the waste liquid and remove the impurities in the waste liquid. Through the cooperation of the above structure, the filter screen 404 can separate the solid impurities and electroplating waste liquid in the mixture, better remove the solid impurities from the tank, and improve the quality of solid-liquid separation. When it is necessary to accelerate the reaction between waste liquid and precipitant, the electric telescopic rod 511 is activated first. The activation of the electric telescopic rod 511 drives the displacement plate 508 to move inside the strip groove 507. The movement of the displacement plate 508 inside the strip groove 507 drives the connecting rod 509 to move. The movement of the connecting rod 509 drives the sliding plate 504 to move inside the groove 503. The movement of the sliding plate 504 inside the groove 503 drives the rack 505 to move. The movement of the rack 505 meshes with the gear 506, thereby causing the gear 506 to rotate. The rotation of the gear 506 drives the rotating rod 501 to rotate. The rotation of the rotating rod 501 drives the stirring blade 502 to rotate. The rotation of the stirring blade 502 enables efficient mixing and stirring of the precipitant and electroplating waste liquid. Through the cooperation of the above structures, the stirring blade 502 can efficiently mix and stir the precipitant and electroplating waste liquid, thereby improving the purification efficiency of subsequent treatment.
