Description

Technical Field

[0001] This utility model relates to a wastewater treatment system, specifically a cyanide wastewater treatment system, and belongs to the field of wastewater treatment technology. Background Technology

[0002] Cyanide wastewater is a highly toxic type of cyanide-containing wastewater. Long-term, large-scale discharge of low-concentration cyanide-containing wastewater can easily cause widespread groundwater pollution, seriously threatening water supply sources. Cyanide is a highly toxic substance, especially when it is in an acidic pH range, where it transforms into highly toxic hydrogen cyanide. Cyanide-containing wastewater must be treated before being discharged into sewers or rivers. Currently, the most mature technology for treating cyanide-containing wastewater is alkaline chlorination. This method involves using chlorine-based oxidants to destroy and remove cyanide under alkaline conditions. First, the cyanide in the wastewater is oxidized to cyanate, and then the cyanate is further oxidized and decomposed into carbon dioxide and water. Only wastewater that has passed the cyanide-breaking reaction can proceed to the next step of treatment. During the cyanide-breaking treatment, relevant reagents need to be added to the wastewater, and after the cyanide-breaking treatment, flocculants also need to be added to the wastewater. Flocculants remove heavy metals and suspended solids in the wastewater through mechanisms such as charge neutralization and adsorption bridging.

[0003] Existing wastewater treatment devices cannot automatically clean impurities adhering to the inner wall of the tank, nor can they clean impurities that precipitate out of the wastewater after it has been mixed with flocculant.

[0004] Therefore, a cyanide wastewater treatment system is proposed here. Utility Model Content

A first bevel gear 402 is fixed to the output end of the motor 401. A rotating rod 403 passes through the surface of the first support plate 3, and a second bevel gear 404 is fixed to the surface of the rotating rod 403.

The movable sleeve 406 passes through the first support plate 3, and a third bevel gear 407 is fixed to the outer circumference of the movable sleeve 406. The three bevel gear 407 meshes with the first bevel gear 402. The lower end of the rotating rod 403 is also connected to the movable sleeve 406 and the limiting sleeve 409. The movable sleeve 406 and the limiting sleeve 409 are fixed with a cleaning frame 408 on their sides. The side of the cleaning frame 408 is in close contact with the inside of the treatment tank 1. The cyanide wastewater treatment system can discharge flocculant from the uniformly opened discharge holes on the side of the rotating rod 403 into the inside of the treatment tank 1 through the hollow rotating rod 403, ensuring that the flocculant is evenly mixed with the wastewater. The motor 401 can drive the movable sleeve 406 and the cleaning frame 408 fixed on the side of the movable sleeve 406 to rotate, thereby cleaning the inner wall of the treatment tank 1, preventing impurities from accumulating on the inner wall, helping to improve the overall efficiency of wastewater treatment and preventing blockage.

[0030] Please refer to this carefully. Figure 3 , Figure 5 and Figure 6The cleaning component 5 includes a knob 502 positioned above the cleaning plate 501. A bidirectional threaded rod 503 is fixed to the lower surface of the knob 502. The lower end of the bidirectional threaded rod 503 passes through the placement groove 506 and is rotatably connected to the bottom wall of the placement groove 506. A threaded cap 504 is threadedly connected to the surface of the bidirectional threaded rod 503. A fixing block 505 is fixed to the side of the threaded cap 504. A fixing groove corresponding to the fixing block 505 is opened on the end face of the support rod 405, and the fixing block 505 is snapped into the fixing groove. A filter plate 507 is rotatably connected to the side of the cleaning plate 501. A second support plate 508 is fixed to the side of the cleaning plate 501. A pull rod 509 passes through the surface of the second support plate 508, and the lower end of the pull rod 509 is fixed to the bottom wall of the placement groove. A limiting block 510 is fixed, and a spring is sleeved on the surface of the pull rod 509. The side of the limiting block 510 is in contact with the filter plate 507. The surface of the second support plate 508 is movably engaged with the stop block 511, which is located on the side of the pull rod 509. A water passage groove 512 is opened on the other side of the cleaning plate 501. This cyanide wastewater treatment system can effectively separate and collect precipitates from wastewater through the cleaning component 5 installed on the stirring rod, thereby improving the efficiency of wastewater treatment. In addition, the cleaning plate 501 automatically collects and filters precipitates during the stirring process, which not only reduces the interference between flocculants and precipitates, thereby improving the mixing effect of wastewater and flocculants, but also effectively prevents precipitates from being resuspended or remaining in the wastewater, thereby reducing the risk of secondary pollution.

[0031] The rotating rod 403 is a hollow rod with a drug discharge hole on its side. The top of the rotating rod 403 is connected to an external infusion pipe, and a drain pipe is installed on the side of the treatment tank 1.

[0032] When using this utility model: First, place the device in the designated position. Then, the operator pours cyanide wastewater into the treatment tank 1 and injects the relevant reagents into the rotating rod 403 through the infusion pipe. The reagents are then mixed with the cyanide wastewater through the discharge hole on the side of the rotating rod 403. After the cyanide wastewater and the relevant reagents have reacted, the flocculant is injected into the treatment tank 1 through the rotating rod 403 through the infusion pipe. Then, the operator controls the motor 401 to operate through the control equipment. The motor 401 drives the first bevel gear 402 to rotate, the first bevel gear 402 drives the second bevel gear 404 to rotate, and the second bevel gear 404 drives the rotating rod 403 to rotate, thereby driving the cleaning plate 501 installed on the support rod 405 to rotate. This allows the flocculant and wastewater to be fully mixed. The wastewater enters the cleaning plate 501 through the water tank 512 and is discharged through the filter plate 507 that is rotatably connected to the side of the cleaning plate 501. The impurities generated during the flocculation process are trapped inside the cleaning plate 501 by the filter plate 507.

[0033] Meanwhile, the first bevel gear 402 can also drive the third bevel gear 407 to rotate. The third bevel gear 407 drives the movable sleeve 406 to rotate, thereby driving the cleaning frame 408 fixed on the side of the movable sleeve 406 to rotate. Since the side of the cleaning frame 408 is in contact with the inside of the treatment tank 1, the cleaning frame 408 can clean the inner wall of the treatment tank 1 during rotation.

[0034] After the wastewater treatment is completed, the staff drains the wastewater from the treatment tank 1 through the drain pipe. Then, the lifting unit 2 is operated by the control equipment. The lifting unit 2 moves the first support plate 3 upward, thereby moving the rotating component 4 and the cleaning component 5 synchronously. Then, the staff turns the knob 502, which drives the bidirectional threaded rod 503 to rotate. The bidirectional threaded rod 503 drives the threaded cap 504 to move, thereby moving the fixing block 505 fixed on the side of the threaded cap 504, causing the fixing block 505 to disengage from the fixing groove. The staff can then remove the cleaning plate 501 from the support rod 405. Then, the staff pulls the pull rod 509, which moves the limit block 510, separating the limit block 510 from the filter plate 507. Then, the staff pushes the stop block 511, so that the stop block 511 is below the pull rod 509, thereby restricting the position of the pull rod 509. The staff can then open the filter plate 507 to clean the impurities inside the cleaning plate 501 and the impurities on the surface of the filter plate 507.
