Description

Technical Field

[0001] This utility model relates to the field of heavy metal treatment technology, specifically to a heavy metal treatment device for wastewater from battery dismantling and recycling. Background Technology

[0002] Wastewater generated during battery dismantling and recycling typically contains heavy metals such as lead, cadmium, mercury, nickel, and cobalt. If not properly treated, it can cause serious harm to the environment and human health. It needs to be treated by chemical precipitation equipment. By adding chemical agents (such as sodium hydroxide, sodium sulfide, etc.) to the wastewater, the heavy metal ions react with the agents to form insoluble precipitates. Then, the precipitates are separated from the wastewater by solid-liquid separation equipment (such as sedimentation tanks, clarification tanks, etc.).

[0003] The filter plates on the chemical precipitation equipment are connected by bolts, and specific tools are required for disassembly and assembly, which affects work efficiency. In addition, after solid-liquid separation of heavy metal precipitates and water in wastewater, the heavy metal precipitates still contain a certain amount of water. The water will increase the volume of the heavy metal precipitates and make them loose and flocculent. The large and loose volume of the heavy metal precipitates makes them inconvenient for subsequent treatment and disposal. Improvements should be made to address these issues.

[0004] Therefore, a heavy metal treatment device for wastewater from battery dismantling and recycling is proposed. Summary of the Invention

[0005] The purpose of this utility model is to provide a heavy metal treatment device for wastewater from battery dismantling and recycling in order to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model specifically adopts the following technical solution: A heavy metal treatment device for wastewater from battery dismantling and recycling includes a sedimentation tank and an electric actuator. The electric actuator is fixedly installed on one side of the sedimentation tank. The sedimentation tank has an internal frame, and the telescopic end of the electric actuator is fixedly connected to one side of the frame. The surface of the frame is provided with a filter plate for solid-liquid separation of precipitates and water. The surface of the filter plate and the top of the frame are provided with locking mechanisms for locking the filter plate and the frame. The surface of the locking mechanism is provided with an unlocking mechanism for releasing the locking mechanism from locking the filter plate. One side surface and the top of the sedimentation tank are provided with a device for... The dehydration assembly for squeezing materials includes a locking mechanism comprising a connecting rod, a connecting rod fixedly mounted on the surface of the filter plate, a guide rail fixedly mounted on the top of the frame, a groove on the surface of the guide rail, a cavity at the top of one end of the connecting rod, a movable block slidably mounted inside the cavity, and a locking spring fixedly mounted on the opposite surface of the top of the movable block and the inner bottom of the cavity. Two sets of the connecting rod, guide rail, movable block, and locking spring are provided, and both sets of the connecting rod are slidably connected to the top of the frame. One side of each set of the movable blocks has a rounded corner.

[0007] Furthermore, the unlocking mechanism includes a slider, which is slidably disposed inside the guide rail. A return spring is fixedly disposed on the opposite side of the bottom of the slider and the inner bottom of the guide rail. A crossbar is fixedly disposed on the surface of the slider, and the crossbar is located above the movable block.

[0008] Furthermore, the two ends of the crossbar are fixedly connected to the surfaces of the two sets of sliders, and the crossbar is located above the two sets of movable blocks, with the crossbar parallel to the top of the frame.

[0009] Furthermore, the dewatering component includes a fixing plate, a fixing plate is fixedly provided on one side surface of the sedimentation tank, an L-shaped plate is fixedly provided on the surface of the fixing plate, and a squeezing plate is fixedly provided at the bottom end of the L-shaped plate, with the squeezing plate located directly above the sedimentation tank.

[0010] The beneficial effects of this utility model are as follows: This invention uses a locking mechanism to lock the filter plate and frame, and an unlocking mechanism to release the lock. The locking and unlocking mechanisms facilitate the disassembly and assembly of the filter plate, improving efficiency. An electric push rod drives the frame and filter plate upwards, causing the surface of the dewatering component to contact the heavy metal precipitate at the bottom inner side of the filter plate. Under pressure, the water in the metal precipitate is squeezed out, reducing its volume and compressing it into a compact block. The electric push rod and dewatering component then dehydrate the metal precipitate, facilitating subsequent processing and disposal. Attached Figure Description

[0016] like Figures 1 to 4As shown, a heavy metal treatment device for wastewater from battery dismantling and recycling includes a sedimentation tank 1 and an electric push rod 2. The electric push rod 2 is fixedly installed on one side of the sedimentation tank 1. A frame 3 is provided inside the sedimentation tank 1, and the telescopic end of the electric push rod 2 is fixedly connected to one side of the frame 3. A filter plate 4 for solid-liquid separation of sediment and water is provided on the surface of the frame 3. A locking mechanism 5 for locking the filter plate 4 and the frame 3 is provided on the surface of the filter plate 4 and the top of the frame 3. Figure 3 , Figure 4 As shown, specifically, the locking mechanism 5 includes a connecting rod 501. The connecting rod 501 is fixedly provided on the surface of the filter plate 4. The top of the frame 3 is fixedly provided with a guide rail 502. The surface of the guide rail 502 is provided with a slot 503. A cavity 504 is provided at the top of one end of the connecting rod 501. A movable block 505 is slidably provided inside the cavity 504. A locking spring 506 is fixedly provided on the opposite side of the top of the movable block 505 and the inner bottom of the cavity 504. There are two sets of connecting rods 501 and guide rails 502, as well as movable blocks 505 and locking springs 506. Both sets of connecting rods 501 are slidably connected to the top of the frame 3. One side of both sets of movable blocks 505 is rounded.

[0017] More specifically, one end of the connecting rod 501 passes through the slot 503, thereby pressing the movable block 505, causing the movable block 505 to embed into the cavity 504 and press the locking spring 506. When the movable block 505 is on the other side of the guide rail 502, the movable block 505 is reset under the action of the locking spring 506, thereby realizing the connection between the connecting rod 501 and the guide rail 502, and thus realizing the connection between the filter plate 4 and the frame 3. The inner wall of the slot 503 presses the rounded edge of the movable block 505, thereby facilitating the downward movement of the movable block 505. Since the two sets of connecting rods 501 are slidably connected to the top of the frame 3, the frame 3 can longitudinally limit the two sets of connecting rods 501, thereby longitudinally limiting the filter plate 4.

[0018] The surface of the locking mechanism 5 is provided with an unlocking mechanism 6 for releasing the locking mechanism 5 from locking the filter plate 4, such as... Figure 3 , Figure 4 As shown, specifically, the unlocking mechanism 6 includes a slider 601, which is slidably disposed inside the guide rail 502. A return spring 602 is fixedly disposed on the bottom surface of the slider 601 opposite to the inner bottom surface of the guide rail 502. A crossbar 603 is fixedly disposed on the surface of the slider 601, and the crossbar 603 is located above the movable block 505. The two ends of the crossbar 603 are fixedly connected to the surfaces of two sets of sliders 601 respectively, and the crossbar 603 is located above the two sets of movable blocks 505. The crossbar 603 is parallel to the top of the frame 3.

[0019] More specifically, pressing down on the horizontal bar 603 causes the slider 601 to slide vertically downwards, thereby compressing the return spring 602. The horizontal bar 603 moves downwards and abuts against the rounded edge of the movable block 505, causing the movable block 505 to embed into the cavity 504. At this time, pulling the filter plate 4 pulls one end of the connecting rod 501 out of the slot 503, thereby unlocking the filter plate 4. Pressing down on the horizontal bar 603 causes the bottom of the horizontal bar 603 to abut against the rounded edge of the two sets of movable blocks 505, causing the two sets of movable blocks 505 to move downwards simultaneously, thereby improving the disassembly efficiency of the filter plate 4.

[0020] The sedimentation tank 1 is provided with a dewatering component 7 on one side and above for squeezing the sediment, such as... Figure 1 , Figure 2 As shown, specifically, the dewatering component 7 includes a fixing plate 701, a fixing plate 701 is fixedly provided on one side surface of the sedimentation tank 1, an L-shaped plate 702 is fixedly provided on the surface of the fixing plate 701, and a squeezing plate 703 is fixedly provided at the bottom end of the L-shaped plate 702, and the squeezing plate 703 is located directly above the sedimentation tank 1.

[0021] More specifically, the electric push rod 2 drives the frame 3 and filter plate 4 to move upward. The metal precipitate is located at the bottom inner side of the filter plate 4. When the bottom of the extrusion plate 703 comes into contact with the metal precipitate, the metal precipitate is squeezed under the action of force, thereby performing dehydration on the metal precipitate.

[0022] In summary: When an appropriate amount of wastewater and chemical agents are added to the sedimentation tank 1, the heavy metal ions in the wastewater react chemically with the agents to form insoluble precipitates. The precipitates are located at the bottom inner side of the filter plate 4. The filter plate 4 and the frame 3 can be locked by the locking mechanism 5, and the locking mechanism 6 can be released from the locking mechanism 5. The locking mechanism 5 and the unlocking mechanism 6 facilitate the disassembly and assembly of the filter plate 4, thereby improving the disassembly and assembly efficiency. The electric push rod 2 drives the frame 3 and the filter plate 4 to move upward, so that the surface of the dewatering component 7 comes into contact with the heavy metal precipitates at the bottom inner side of the filter plate 4. Under the action of pressure, the water in the metal precipitates is squeezed out, thereby reducing the volume of the metal precipitates and compressing them into a compact block. Under the action of the electric push rod 2 and the dewatering component 7, the metal precipitates are dewatered, which facilitates subsequent treatment and disposal.

[0023] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
