Description

Technical Field

[0001] This utility model relates to the field of wastewater purification technology, specifically a heavy metal wastewater purification and recovery device. Background Technology

[0002] 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 metals in heavy metal wastewater generally cannot be decomposed or destroyed; they can only be relocated or their physical and chemical forms changed.

[0003] Heavy metal wastewater treatment methods are generally divided into two categories. One is to transform dissolved heavy metals in the wastewater into insoluble heavy metal compounds or elements, which are then removed from the wastewater through precipitation and flotation. The other is to concentrate and separate the heavy metals in the wastewater without changing their chemical form. In the process of heavy metal wastewater treatment, impurities in the wastewater need to be filtered through filter plates. However, existing technologies cannot self-clean impurities on the filter plates, which leads to clogging of the filter plates and affects the filtration of metal wastewater. Therefore, those skilled in the art have proposed a heavy metal wastewater purification and recovery device to solve the problems mentioned in the background. Utility Model Content

[0004] The purpose of this invention is to provide a heavy metal wastewater purification and recycling device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A heavy metal wastewater purification and recovery device includes a base with two supports on each side. A housing is mounted on the supports, and a feeding hopper is mounted on the housing. A hollow storage cylinder is installed inside the housing. Rotating plates that rotatably fit against the outer wall of the storage cylinder are mounted on both sides of the housing. Multiple connecting rods arranged in a ring-shaped interval are installed between the two rotating plates. Multiple mounting brackets arranged in a ring-shaped interval are provided on the outer wall of the rotating plates. The mounting brackets have slots in which cleaning filter plates are movably mounted. A discharge port is provided at the top of the storage cylinder. A filter screen is provided at the bottom of the housing. A driving component is installed on one side of the housing to drive the rotating plates to rotate around the storage cylinder. A driving component for driving the rotating plates to rotate is installed on the outer side of the housing.

[0007] As a further embodiment of this utility model: a curved groove is provided on one side of the housing, which is connected to a curved groove, and the curved groove and the curved groove form a closed path. Limiting posts are installed on both sides of the cleaning filter plate, and the limiting posts can be slidably connected to the curved groove and the curved groove. As a further embodiment of this utility model:

[0008] As a further improvement of this utility model, the bending groove is located on one side of the discharge port.

[0009] As a further embodiment of this utility model: the driving component includes a support base installed on one side of the housing, a motor installed on the support base, a second gear installed on the output shaft of the motor, and a first gear installed on the rotating plate, the first gear meshing with the second gear.

[0010] As a further improvement of this utility model, the feeding position of the feeding hopper is offset from the center of the box.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model pours heavy metal wastewater into the tank through a feeding hopper, and then filters and removes impurities from the wastewater through a filter screen at the bottom of the tank. During this process, a drive component can drive a rotating plate to rotate, causing the mounting bracket on the rotating plate to rotate, thereby driving the cleaning filter plate to rotate. The cleaning filter plate cleans the impurities accumulated on the filter screen and rotates to the discharge port. The impurities on the cleaning filter plate will fall into the discharge port and enter the storage cylinder. During the rotation of the cleaning filter plate at the discharge port, there will be some shaking, which is more conducive to pouring the impurities cleaned on the cleaning filter plate into the discharge port. The effect is better. Compared with the prior art, the rotating cleaning filter plate can achieve self-cleaning of impurities on the filter screen, and with the help of the bending groove and the arc groove, the impurities cleaned by the cleaning filter plate can be shaken off into the storage cylinder, resulting in better performance.

[0017] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0018] Please see Figures 1-4 A heavy metal wastewater purification and recycling device includes a base 1, with two supports 2 installed on both sides of the base 1. A housing 3 is installed on the supports 2, and a feeding hopper 4 is installed on the housing 3. A hollow storage cylinder 5 is installed inside the housing 3. Rotating plates 6 are rotatably arranged on both sides of the housing 3 and fit against the outer wall of the storage cylinder 5. Multiple connecting rods 7 are installed between the two rotating plates 6 in a ring-shaped interval. Multiple mounting brackets 12 are arranged in a ring-shaped interval on the outer wall of the rotating plates 6. The mounting brackets 12 have slots 13, and cleaning filter plates 14 are movably arranged in the slots 13. A discharge port 18 is opened at the top of the storage cylinder 5. A filter screen 19 is installed at the bottom of the housing 3. A driving component is installed on one side of the housing 3 to drive the rotating plates 6 to rotate around the storage cylinder 5. A driving component for driving the rotating plates 6 to rotate is installed on the outside of the housing 3.

[0019] Heavy metal wastewater is poured into the tank 3 through the feeding hopper 4. The wastewater is then filtered and impurities are removed through the filter screen 19 at the bottom of the tank 3. During this process, the rotating plate 6 is driven by the drive component to rotate, which in turn drives the mounting bracket 12 on the rotating plate 6 to rotate, thereby driving the cleaning filter plate 14 to rotate. The cleaning filter plate 14 cleans the impurities accumulated on the filter screen 19 and rotates to the discharge port 18. The impurities on the cleaning filter plate 14 fall into the discharge port 18 and enter the storage cylinder 5. During the rotation of the cleaning filter plate 14 at the discharge port 18, it will also shake, which makes it easier to pour the impurities cleaned on the cleaning filter plate 14 into the discharge port 18, resulting in better performance.

[0020] In one embodiment, an arc groove 16 is provided on one side of the housing 3, the arc groove 16 is connected to a bending groove 17, and the arc groove 16 and the bending groove 17 form a closed path. Limiting posts 15 are installed on both sides of the cleaning filter plate 14, and the limiting posts 15 can be slidably connected with the arc groove 16 and the bending groove 17.

[0021] In one embodiment, the bending groove 17 is located on one side of the discharge port 18.

[0022] As the rotating plate 6 rotates, it drives the mounting frame 12 to rotate, causing the cleaning filter plate 14 to rotate around the storage cylinder 5. During this process, the limiting posts 15 on both sides of the cleaning filter plate 14 will first slide in the curved groove 16. At this time, the two ends of the cleaning filter plate 14 are respectively attached to the storage cylinder 5 and the inner wall of the box 3. When the cleaning filter plate 14 rotates to the discharge port 18 of the storage cylinder 5, the limiting posts 15 will slide into the curved groove 17, causing the cleaning filter plate 14 to slide back and forth along the slot 13 of the mounting frame 12, thereby shaking off the impurities cleaned on the cleaning filter plate 14 to the discharge port 18, making it convenient to clean the impurities on the cleaning filter plate 14.

[0023] In one embodiment, the driving component includes a support base 11 mounted on one side of the housing 3, a motor 10 mounted on the support base 11, a second gear 9 mounted on the output shaft of the motor 10, and a first gear 8 mounted on the rotating plate 6, the first gear 8 meshing with the second gear 9.

[0024] The motor 10 is started, and the rotating plate 6 is driven to rotate through the meshing first gear 8 and second gear 9. The rotating plate 6 is driven to rotate through the connecting rod 7, so that the two rotating plates 6 rotate synchronously, thereby driving the cleaning filter plate 14 to rotate synchronously.

[0025] In one embodiment, the feeding position of the feeding hopper 4 is offset from the middle of the box 3, and the discharge port of the feeding hopper 4 is offset from the discharge port 18 of the storage cylinder 5, so that the heavy metal wastewater discharged from the feeding hopper 4 can fall directly onto the filter screen 19 for impurity removal.

[0026] The working principle of this utility model is as follows: During use, heavy metal wastewater is poured into the tank 3 through the feeding hopper 4. The wastewater is then filtered and impurities are removed through the filter screen 19 at the bottom of the tank 3. During this process, the drive component can drive the rotating plate 6 to rotate, causing the mounting bracket 12 on the rotating plate 6 to rotate, thereby driving the cleaning filter plate 14 to rotate. The cleaning filter plate 14 cleans the impurities accumulated on the filter screen 19 and rotates to the discharge port 18. The impurities on the cleaning filter plate 14 fall into the discharge port 18 and enter the storage cylinder 5. During the rotation of the cleaning filter plate 14 at the discharge port 18, the cleaning filter... The limiting posts 15 on both sides of the plate 14 will slide from the curved groove 16 to the bending groove 17, so that the cleaning filter plate 14 can slide back and forth along the slot 13 of the mounting frame 12, thereby shaking off the impurities cleaned on the cleaning filter plate 14 into the discharge port 18, which is more conducive to pouring the impurities cleaned on the cleaning filter plate 14 into the discharge port 18, and the use effect is better. Compared with the prior art, the rotatable cleaning filter plate 14 can realize the self-cleaning of impurities on the filter screen 19, and in conjunction with the bending groove 17 and the curved groove 16, the impurities cleaned by the cleaning filter plate 14 can be shaken off into the storage cylinder 5, and the use effect is better.
