Description

Technical Field

[0001] This utility model relates to the field of industrial wastewater treatment technology, specifically to a high-efficiency treatment device for industrial wastewater containing heavy metals. Background Technology

[0002] Heavy metal-containing industrial wastewater treatment involves adding chemical agents to the wastewater, causing heavy metal ions to react with the agents (chelating agents) to form insoluble precipitates, thus facilitating wastewater treatment. Different wastewaters require different chemical treatment agents, allowing for targeted treatment of different industrial wastewaters to improve treatment speed.

[0003] According to Chinese Patent Publication No. CN222389660U, entitled "A High-Efficiency Treatment Device for Industrial Wastewater Containing Heavy Metals," the main method involves removing a thin-walled inner liner from the chelation tank, then disassembling the circumferential wall and the trough-shaped bottom wall of the thin-walled inner liner. This facilitates cleaning the thin-walled inner liner, and because it uses less material, it can be directly replaced if necessary. The ability to directly replace the thin-walled inner liner helps ensure the efficiency of wastewater treatment. Then, by removing the seals and using tools to clear blockages, the problem of clogged outlet pipes can be addressed.

[0004] Some industrial wastewater containing heavy metals can be treated using chelating agents and chelating tanks. The thin inner wall of the chelating tank, which can be moved and disassembled, makes it easy to clean the chelating tank regularly. However, the stubborn and difficult-to-remove deposits in the industrial wastewater containing heavy metals require regular treatment, which creates maintenance intervals and reduces the efficiency of industrial wastewater treatment. Utility Model Content

[0005] In view of the deficiencies in the existing technology, this utility model provides a high-efficiency treatment device for industrial wastewater containing heavy metals, so as to improve the treatment efficiency of industrial wastewater containing heavy metals and extend the maintenance cycle of the treatment equipment.

[0006] The technical solution adopted by this utility model to solve the technical problem is: a high-efficiency treatment device for industrial wastewater containing heavy metals, including a treatment tank, a support column, an inlet, and a sealing plate. A filter plate is in contact with the inside of the treatment tank. An inclined surface is provided at the bottom of the treatment tank. A first sleeve is fixedly connected to one side of the filter plate. A first motor is fixedly connected to the sealing plate above the first sleeve. A screw is fixedly connected to the output end of the first motor, and the screw is threadedly connected to the first sleeve. A second motor is fixedly connected to the sealing plate. A limit rod is fixedly connected to the output end of the second motor. A second sleeve is sleeved on the limit rod. The upper end of the second sleeve is rotated via a bearing. A connecting sleeve is provided, and the connecting sleeve is slidably connected to a limiting rod. Stirring blades are fixedly connected to the upper sides of the connecting sleeve that are far apart from each other. The second sleeve is fixedly connected to the center of the filter plate. A pad is rotatably connected to the bottom end of the screw. The bottom end of the pad is fitted with a limiting sleeve. The limiting sleeve is fixedly connected to the bottom inclined surface inside the processing box. Three pads are provided. Another pad is fixedly connected to the limiting rod. A third sleeve is fixedly connected to the side of the filter plate away from the first sleeve. A discharge chute is opened on one side of the processing box. A guide groove is fixedly connected to the processing box at the discharge chute. A liquid level sensor is fixedly connected to the processing box above the discharge chute.

[0007] As a preferred technical solution of this utility model, the bottom ends of the first sleeve, the second sleeve and the third sleeve are all fixedly connected with folding covers, and the other three folding covers are respectively fixedly connected to the upper ends of the first sleeve, the connecting sleeve and the third sleeve. By setting the folding covers, the direct contact between wastewater and the first sleeve, the second sleeve and the third sleeve is reduced.

[0008] As a preferred technical solution of this utility model, a baffle is provided on the inner side of the folding cover. The baffle is fixedly connected to the bottom end of the sealing plate. The baffle is movably inserted into the first sleeve, the second sleeve and the third sleeve respectively. By setting the baffle, the folding cover can be supported, reducing the folding cover from being squeezed by water and contacting the screw or the limiting rod, thus affecting the up and down movement of the filter plate.

[0009] As a preferred technical solution of this utility model, a connecting cover is fixedly connected to the upper end of the filter plate. The connecting cover contacts the inner wall of the treatment box. By setting the connecting cover, the contact surface can be increased, and the cleaning effect can be improved during the up and down movement of the filter plate.

[0010] As a preferred technical solution of this utility model, a guide pipe is fixedly connected to one side of the treatment box, and a water pump is fixedly connected to the treatment box at the guide pipe. By setting the water pump and the guide pipe, the water at the bottom of the filter plate can be pumped back to the top of the filter plate inside the treatment box, thereby improving the filtration quality.

[0011] This utility model has the following advantages: a processing box with an inclined structure at the bottom is used in conjunction with a filter plate. Then, a screw driven by a first motor rotates and moves the filter plate up and down inside the processing box to clean the inner wall. Then, a second motor limit rod and connecting sleeve rotate to make the stirring blades stir. At the same time, when the filter plate moves to the discharge trough, the inclined structure of the filter plate can guide the metal debris to the guide trough, which can remove the metal debris in the wastewater at any time, improve the processing efficiency, and extend the maintenance cycle of the processing equipment.

[0016] The present invention will be further described below with reference to the accompanying drawings.

[0017] Please refer to the following: Figure 1-3The device shown is a high-efficiency treatment device for industrial wastewater containing heavy metals, including a treatment tank 1, a support column 2, an inlet 3, and a sealing plate 4. A filter plate 5 is in contact with the inside of the treatment tank 1. An inclined surface is provided at the bottom of the treatment tank 1. The inclined surface, combined with gravity, guides debris to its lowest point. A first sleeve 6 is fixedly connected to one side of the filter plate 5. A first motor is fixedly connected to the sealing plate 4 above the first sleeve 6. The first motor drives a screw 7 to rotate. Simultaneously, the filter plate 5 is limited by the inner wall of the treatment tank 1, allowing it to move up and down within the treatment tank 1. The outer edge of the filter plate 5 contacts the inner wall of the treatment tank 1, effectively cleaning the inner wall. A screw 7 is fixedly connected to the output end of the first motor, and the screw 7 is threadedly connected to the first sleeve 6. A second motor is fixedly connected to the sealing plate 4. The second motor drives a limiting rod 8 to rotate, causing the connecting sleeve 10 and the stirring blades 11 to rotate, thus mixing the liquid introduced through the inlet 3. During water intake, the filter plate 5 is located at its lowest point within the treatment tank 1. A limiting rod 8 is fixedly connected to the output end. Protrusions are fixedly connected to all four sides of the limiting rod 8, and grooves corresponding to the protrusions are provided on the connecting sleeve 10. A second sleeve 9 is sleeved on the limiting rod 8. The connecting sleeve 10 is rotatably connected to the upper end of the second sleeve 9 via a bearing. The connecting sleeve 10 is slidably connected to the limiting rod 8. Stirring blades 11 are fixedly connected to the upper, mutually distancing sides of the connecting sleeve 10. The center of the filter plate 5 is fixedly connected to the second sleeve 9. A pad is rotatably connected to the bottom end of the screw 7, and a limiting rod is sleeved on the bottom end of the pad. The limiting sleeve 12 is fixedly connected to the bottom inclined surface of the processing box 1. Three pads are provided, and another pad is fixedly connected to the limiting rod 8. The filter plate 5 is fixedly connected to the third sleeve 13 on the side away from the first sleeve 6. A discharge chute 14 is opened on one side of the processing box 1. A guide groove 15 is fixedly connected to the processing box 1 at the discharge chute 14 to discharge metal scraps. A liquid level sensor 16 is fixedly connected to the processing box 1 above the discharge chute 14 to monitor the liquid level in the processing box 1.

[0018] The bottom ends of the first sleeve 6, the second sleeve 9 and the third sleeve 13 are all fixedly connected with folding covers 17, and the other three folding covers 17 are fixedly connected to the upper ends of the first sleeve 6, the connecting sleeve 10 and the third sleeve 13 respectively. By setting multiple folding covers 17, the liquid and metal impurities in the liquid can be prevented from contacting the screw 7, the limiting rod 8 and the stop rod 18, thereby reducing motion sluggishness.

[0019] The inner side of the folding cover 17 is provided with a baffle 18, which is fixedly connected to the bottom end of the sealing plate 4. The baffle 18 is movably inserted into the first sleeve 6, the second sleeve 9 and the third sleeve 13 respectively. The four baffles 18 are a group. By setting the baffles 18, the inner side of the folding cover 17 is blocked, which can reduce the impact of water pressure on the folding cover 17 and directly contact the screw 7, the limiting rod 8 and the baffle 18, further reducing the sticking caused when the filter plate 5 moves up and down.

[0020] The filter plate 5 is fixedly connected to the upper end of the connecting cover 19, which contacts the inner wall of the treatment box 1. The connecting cover 19 and the discharge trough 14 are respectively provided with grooves. That is, when the connecting cover 19 moves up, the grooves correspond to the discharge trough 14. By setting the connecting cover 19, the contact surface between the filter plate 5 and the inner wall of the treatment box 1 can be increased, thereby improving the cleaning effect.

[0021] The treatment box 1 is fixedly connected to a guide pipe 20 on one side, and a water pump 21 is fixedly connected to the treatment box 1 at the guide pipe 20. By setting the water pump 21, the water at the bottom of the filter plate 5 can be pumped to the top of the filter plate 5, thereby improving the treatment effect.

[0022] Among them, the first motor, the second motor, the water pump 21 and the liquid level sensor 16 are all common models on the market, and can be purchased and used according to needs.

[0023] Working principle: The molten metal and treatment agent enter the treatment tank 1 through the inlet 3. The liquid level sensor 16 provides monitoring. At this time, the second motor drives the limit rod 8 to rotate, which enables the connecting sleeve 10 and the stirring blade 11 to rotate, stirring the water and mixing the metal wastewater with the treatment agent. At this time, the water pump 21 pumps the water at the bottom of the filter plate 5 to the top of the filter plate 5, which can reduce the metal particles or flocs at the bottom of the filter plate 5. When dirt adheres to the inner wall of the treatment tank 1, the first motor is started to drive the screw 7 to rotate, which can move the filter plate 5 upward, and move the metal particles and flocs in the water out from the discharge trough 14 and the guide trough 15. At the same time, the edge of the filter plate 5 and the connecting cover 19 can clean the inner wall of the treatment tank 1 during the movement.

[0024] The above are merely preferred embodiments of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.

[0025] All other parts of this utility model that are not described in detail belong to the prior art, and therefore will not be described in detail here.

[0026] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
