Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and in particular to a heavy metal wastewater treatment device. Background Technology

[0002] Heavy metal wastewater refers to wastewater containing heavy metals discharged during industrial production processes such as mining, metallurgy, machinery manufacturing, chemical industry, electronics, and instrumentation. Heavy metal wastewater (containing cadmium, nickel, mercury, zinc, etc.) is one of the most serious forms of industrial wastewater pollution and poses the greatest threat to human health. Its quality and quantity are related to the production process. Heavy metal wastewater treatment equipment is typically used before it is discharged.

[0003] A search revealed a heavy metal wastewater treatment device with authorization announcement number CN219384878U. Its structure includes a reaction tank and a mixer fixedly installed inside the reaction tank. A filter plate is fixed to the side of the reaction tank away from the mixer. The reaction tank also includes a sealing assembly, which comprises a baffle fixed inside the reaction tank near the mixer, a sealing plate below the baffle, and an electric telescopic rod fixed to one side of the reaction tank via a connecting plate. By installing the sealing assembly at the outlet on the baffle, the heavy metal wastewater and additives can fully react before being discharged through the outlet, preventing residual heavy metals in the wastewater from being unresolved and thus avoiding pollution, thereby improving the treatment effect of heavy metal wastewater.

[0004] However, when the above-mentioned device uses a filter plate to filter impurities in the heavy metal wastewater after the reaction, the filter pores of the filter plate are easily clogged by impurities. Once clogged, the wastewater filtration work cannot proceed normally, and it is difficult to quickly resolve the problem after the blockage.

[0005] Therefore, it is necessary to provide a heavy metal wastewater treatment device to solve the above-mentioned technical problems. Utility Model Content

The terms "first," "second," etc., in the specification or the foregoing drawings are used to distinguish different objects, not to describe a specific order; the terms "inner," "outer," "left," and "right" indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention.

[0018] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0019] This utility model provides a heavy metal wastewater treatment device, such as... Figure 1-3 As shown, the heavy metal wastewater treatment device includes: a shell 1, a bucket 2 fixedly installed on the inner wall of the shell 1, and a through pipe 3 fixedly installed at the bottom of the bucket 2; a filter screen cylinder 4 fixedly installed on the inner wall of the shell 1 for filtering heavy metal wastewater, the filter screen cylinder 4 being fixedly connected to the through pipe 3; a cylinder 5 fixedly installed on the shell 1, the cylinder 5 being fixedly connected to the filter screen cylinder 4, and a discharge pipe 6 fixedly installed on the cylinder 5; a stirring mechanism assembled on the shell 1 for treating heavy metal wastewater; a blocking mechanism provided on the shell 1 for blocking the through pipe 3; and a cleaning mechanism installed on the shell 1 for cleaning impurities in the filter screen cylinder 4.

[0020] In this embodiment, when using the device to treat heavy metal wastewater, heavy metal wastewater and additives for treating heavy metal wastewater need to be injected into the interior of the housing 1 from the top of the device. The injected heavy metal wastewater and additives will be above the hopper 2. Then, the stirring mechanism is activated to mix and stir the heavy metal wastewater and additives, which can promote the reaction efficiency of the heavy metal wastewater and additives. After sufficient reaction, the shielding mechanism is activated to release the shielding work on the through pipe 3, so that the reacted heavy metal wastewater can enter the filter cylinder 4 from the through pipe 3, so that the heavy metal wastewater can be filtered to remove impurities. The filtered impurities will remain in the filter cylinder 4, while the filtered heavy metal wastewater will pass through the mesh of the filter cylinder 4 and flow to the bottom of the housing 1, and then be discharged from the bottom of the device. During this process, in order to ensure that the filter cylinder 4 is not blocked by impurities, the cleaning mechanism needs to be activated at the same time. The cleaning mechanism will continuously push the impurities in the filter cylinder 4 towards the cylinder 5, and then discharge them from the discharge pipe 6. In this way, the stability of the device in filtering heavy metal wastewater can be effectively improved.

[0021] In a further preferred embodiment of the present invention, the stirring mechanism includes: a rotating shaft 7 rotatably mounted on the housing 1, with a plurality of stirring rods 8 welded on the rotating shaft 7; and a first servo motor 9 fixedly mounted on the top of the housing 1, the output shaft of the first servo motor 9 being fixedly connected to the top end of the rotating shaft 7.

[0022] In this embodiment, the stirring mechanism is used to treat heavy metal wastewater. When working, the first servo motor 9 drives the rotating shaft 7 to rotate on the housing 1. The rotating shaft 7 drives multiple stirring rods 8 to rotate, stirring and mixing the heavy metal wastewater and additives in the housing 1, thereby promoting the reaction efficiency of heavy metal wastewater and additives.

[0023] In a further preferred embodiment of this utility model, the shielding mechanism includes: a screw 10 rotatably mounted on the housing 1, a connecting plate 12 threadedly mounted on the screw 10, a baffle 13 fixedly mounted on the connecting plate 12, the baffle 13 being slidably connected to the through pipe 3 in a sealed manner, and the baffle 13 contacting the inner wall of the through pipe 3; and a second servo motor 11 fixedly mounted on one side of the housing 1, the output shaft of the second servo motor 11 being fixedly connected to one end of the screw 10.

[0024] In this embodiment, the blocking mechanism is used to block the through pipe 3 and can also release the blockage of the through pipe 3. When it is necessary to discharge the heavy metal wastewater above the bucket 2 into the filter cylinder 4, the second servo motor 11 needs to be started to drive the screw 10 to rotate. The screw 10 will drive the connecting plate 12 and the baffle 13 to move horizontally, so that the baffle 13 separates from the inner wall of the through pipe 3. After separation, the heavy metal wastewater above the bucket 2 can enter the filter cylinder 4. Conversely, the baffle 13 can contact the inner wall of the through pipe 3 to block the through pipe 3. A rubber sealing layer is also provided on the outside of the baffle 13 to better block the through pipe 3.

[0025] In a further preferred embodiment of this utility model, the cleaning mechanism includes: a rotating rod 15 rotatably mounted on the housing 1, a spiral blade 16 fixedly sleeved on the rotating rod 15, the spiral blade 16 contacting the inner wall of the filter screen cylinder 4, and the spiral blade 16 contacting the inner wall of the cylinder 5; and a third servo motor 17 fixedly mounted on the outer wall of the housing 1, the output shaft of the third servo motor 17 being fixedly connected to one end of the rotating rod 15.

[0026] In this embodiment, the cleaning mechanism is used to clean impurities in the filter cylinder 4. During cleaning, the third servo motor 17 is started to drive the rotating rod 15 to rotate. The rotating rod 15 will drive the spiral blade 16 to rotate, so that the spiral blade 16 can push the impurities in the filter cylinder 4 into the cylinder 5. Then, under the action of gravity, they are discharged from the discharge pipe 6, thereby realizing the cleaning of impurities. The cleaning is relatively convenient.

[0027] In a further preferred embodiment of the present invention, a drain pipe 18 and a support frame are fixedly installed at the bottom of the housing 1, and the drain pipe 18 is connected to the interior of the housing 1.

[0028] In this embodiment, the use of drain pipe 18 enables the discharge of heavy metal wastewater after reaction treatment and filtration treatment.

[0029] In a further preferred embodiment of the present invention, a limiting rod 14 is fixedly installed on the inner wall of the housing 1, and the limiting rod 14 is slidably connected to the connecting plate 12.

[0030] In this embodiment, the use of the limiting rod 14 can improve the stability of the connecting plate 12 during horizontal movement. When the screw 10 rotates to drive the connecting plate 12 to move horizontally, the connecting plate 12 will also slide horizontally on the limiting rod 14.

[0031] In a further preferred embodiment of the present invention, a hopper 19 is fixedly installed on the top of the housing 1, a support block is fixedly installed on one side of the housing 1, a collection box is provided on the support block, and the collection box is located below the discharge pipe 6.

[0032] In this embodiment, the use of support blocks and collection boxes makes it convenient for people to collect the impurities discharged from the discharge pipe 6, so that the discharged impurities can be centrally processed.

[0033] In summary, compared with related technologies, this solution, through the use of hopper 19, allows workers to conveniently inject the heavy metal wastewater to be treated and the additives used for treating heavy metal wastewater together into the shell 1, so that the injected heavy metal wastewater and additives are positioned above the hopper body 2. The stirring mechanism can mix and stir the heavy metal wastewater and additives to promote their reaction efficiency. The shielding mechanism can not only seal the through pipe 3, but also release the seal after the heavy metal wastewater and additives have fully reacted, allowing the reaction to proceed smoothly. Good heavy metal wastewater can enter the filter cylinder 4 for impurity filtration. The filtered impurities will remain inside the filter cylinder 4, while the filtered heavy metal wastewater will pass through the mesh of the filter cylinder 4 and flow to the bottom of the housing 1, and then be discharged from the drain pipe 18. Through the use of the cleaning mechanism, the impurities inside the filter cylinder 4 can be pushed towards the cylinder 5 and then discharged from the discharge pipe 6. This can achieve the cleaning of impurities inside the filter cylinder 4, ensuring that the filtration of heavy metal wastewater can operate normally, effectively preventing the mesh of the filter cylinder 4 from being blocked by impurities, and the effect is good.

[0034] It should be understood, in the several embodiments provided in this application, that the disclosed apparatus may be implemented in other ways.
