Description

Technical Field

[0001] This utility model relates to the technical field of heavy metal leaching and removal equipment, specifically to a dynamic leaching and removal equipment for heavy metals in magnesium slag. Background Technology

[0002] Magnesium slag is a common waste product in the production of magnesium and its alloys. It refers to residues and solid wastes with a high magnesium content. Because it contains magnesium, silicon, oxygen, calcium, and other substances, it is grayish-white, yellowish-white, or light gray in color, insoluble in water, and has a certain electrical conductivity. Magnesium slag contains a large amount of heavy metals, so leaching removal equipment is needed to remove the heavy metals from the magnesium slag.

[0003] Existing heavy metal leaching removal equipment for magnesium slag typically involves directly spraying the leaching solution onto the magnesium slag. This method of removing heavy metals from magnesium slag is relatively simple, resulting in poor removal efficiency and slow removal speed. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a dynamic leaching and removal device for heavy metals in magnesium slag, thereby solving the problem that the existing leaching and removal devices for heavy metals in magnesium slag mentioned in the background art have a relatively simple method for removing heavy metals from magnesium slag, resulting in poor removal effect.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a dynamic leaching and removal device for heavy metals in magnesium slag, comprising a leaching tower, a spiral feeding mechanism on one side of the leaching tower, a storage tank, leaching nozzles, a transmission rod, a swing assembly, a mounting column, a receiving plate, a buffer return mechanism, a bottom concealment and interception adsorption mechanism, two storage tanks rotatably mounted on the top of the inner wall of the leaching tower, multiple leaching nozzles connected to the lower side of the storage tanks, a transmission rod mounted on one side of the storage tanks, and the swing assembly disposed on the upper side of the leaching tower. The oscillating assembly is used to oscillate the storage tank. Multiple mounting columns are installed inside the scrubbing tower, and receiving plates are sleeved on the mounting columns. The receiving plates can deflect around the mounting columns. Multiple sets of buffer return mechanisms are installed inside the scrubbing tower, with every four sets of buffer return mechanisms positioned below the corresponding receiving plates. The buffer return mechanisms are used to buffer and return the receiving plates. The bottom chamber is connected to the lower side of the scrubbing tower, and an interception and adsorption mechanism is installed inside the bottom chamber. The interception and adsorption mechanism is used to intercept and adsorb magnesium slag and heavy metals.

[0008] The swing assembly includes a vertical plate, a rotating shaft, a transmission cam, and a transmission frame. The vertical plate is installed on the upper side of the scrubbing tower. Two rotating shafts are rotatably installed on one side of the vertical plate. A driving component for driving the rotating shaft is provided on the vertical plate. The transmission cam is installed on the rotating shaft and rotates synchronously with the rotating shaft. The transmission frame is installed on the upper side of the transmission rod and covers the outside of the transmission cam.

[0009] The buffer return mechanism includes an arc-shaped rod, a pressing block, a sleeve, a limiting rod, and a return spring. The arc-shaped rod is installed on the inner wall of the scrubbing tower, the pressing block is installed on the inner end of the arc-shaped rod, the sleeve is sleeved on the arc-shaped rod and the pressing block and can move along the arc-shaped rod and the pressing block, the upper side of the sleeve is connected to the lower side of the receiving plate, the limiting rod is installed on the inner top wall of the sleeve and inserted into the arc-shaped rod and the pressing block, the return spring is sleeved on the limiting rod, and the two ends of the return spring are respectively connected to the sleeve and the pressing block.

[0010] The interception and adsorption mechanism includes a mounting frame, an interception layer, and a heavy metal adsorption layer. The mounting frame is inserted into the bottom chamber and can move within the bottom chamber. The interception layer is disposed at the top of the inner wall of the mounting frame, and the heavy metal adsorption layer is disposed at the bottom of the inner wall of the mounting frame.

[0011] As a preferred embodiment of the dynamic leaching and removal equipment for heavy metals in magnesium slag described in this utility model, in order to ensure the interception effect of the interception layer on magnesium slag, the interception layer is composed of multiple interception meshes, and the aperture of the multiple interception meshes decreases sequentially from top to bottom.

[0012] As a preferred embodiment of the dynamic leaching and removal equipment for heavy metals in magnesium slag described in this utility model, in order to ensure that the magnesium slag can fall accurately onto the receiving plate, a plurality of baffles are installed on the inner wall of the leaching tower, and the plurality of baffles are respectively positioned above the corresponding mounting columns.

[0013] (III) Beneficial Effects

[0014] Compared with the prior art, this utility model provides a dynamic leaching and removal device for heavy metals in magnesium slag, which has the following beneficial effects:

[0015] In this invention, the cooperation between the mounting column, the receiving plate, and the buffer return mechanism allows the magnesium slag to roll on multiple receiving plates after entering the washing tower. This ensures that the magnesium slag makes full contact with the washing liquid during the rolling process, prolonging the contact time between the magnesium slag and the washing liquid. This achieves dynamic washing of heavy metals in the magnesium slag, enhancing the removal effect of heavy metals. Furthermore, the cooperation between the storage tank, the washing nozzle, the transmission rod, and the swing assembly enables the swing spraying of the washing liquid, ensuring that the washing liquid is sprayed evenly onto the receiving plate, increasing the contact range between the magnesium slag and the washing liquid, and enhancing the effect. To improve the leaching and removal of heavy metals from magnesium slag, this device utilizes a bottom chamber and an interception and adsorption mechanism to separate magnesium slag, heavy metals, and the leaching liquid. This facilitates the secondary use of the leaching liquid. Compared to existing magnesium slag heavy metal leaching and removal equipment, which employs a relatively simple removal method and results in poor removal efficiency, this dynamic leaching and removal equipment for magnesium slag extends the contact time between the magnesium slag and the leaching liquid, enhancing the leaching and removal effect. Furthermore, it allows for the secondary use of the leaching liquid, saving costs. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example

[0026] Please see Figures 1 to 5 This embodiment proposes a dynamic leaching and removal device for heavy metals in magnesium slag, including a leaching tower 1, a spiral feeding mechanism 2 installed on one side of the leaching tower 1, a storage tank 3, leaching nozzles 4, a transmission rod 5, a swing assembly, a mounting column 6, a receiving plate 7, a buffer return mechanism, a bottom chamber 8, and an interception and adsorption mechanism. Compared with existing heavy metal leaching and removal devices for magnesium slag, which have a relatively simple removal method, resulting in poor removal efficiency, this embodiment addresses this issue by coordinating the mounting column 6, the receiving plate 7, and the buffer return mechanism to ensure that the magnesium slag, after entering the leaching tower 1, can be dynamically leached and adsorbed through multiple receiving and adsorption mechanisms. The rolling motion on the material plate 7 allows the magnesium slag to come into full contact with the leachate during the rolling process, extending the contact time between the magnesium slag and the leachate. This enables dynamic leaching of heavy metals in the magnesium slag, enhancing the removal effect of heavy metals. Through the cooperation between the storage tank 3, the leaching nozzle 4, the transmission rod 5, and the swing assembly, the oscillating spray of the leachate is achieved, allowing the leachate to be sprayed evenly onto the material plate 7. This increases the contact range between the magnesium slag and the leachate, enhancing the leaching and removal effect of heavy metals in the magnesium slag. Through the cooperation of the bottom chamber 8 and the interception and adsorption mechanism, the separation of magnesium slag, heavy metals, and leachate is achieved, facilitating the secondary use of the leachate.

[0027] like Figure 1 and Figure 3 As shown, two liquid storage tanks 3 are rotatably installed on the top of the inner wall of the scrubbing tower 1. One side of the liquid storage tank 3 is connected to an external liquid supply device through an external pipe. Multiple scrubbing nozzles 4 are connected to the lower side of the liquid storage tank 3. A transmission rod 5 is installed on one of the two sides of the liquid storage tank 3. Multiple mounting columns 6 are installed inside the scrubbing tower 1. A receiving plate 7 is sleeved on the mounting column 6. Multiple baffles are installed on the inner wall of the scrubbing tower 1. The baffles are located above the corresponding mounting columns 6. The baffles can block the magnesium slag, so that the magnesium slag can fall accurately onto the receiving plate 7. Multiple sets of buffer return mechanisms are set inside the scrubbing tower 1. Every four sets of buffer return mechanisms are located below the corresponding receiving plate 7. The bottom chamber 8 is connected to the lower side of the scrubbing tower 1. The lower side of the bottom chamber 8 is connected to an external liquid storage tank through an external pipe. A support base is installed on the lower side of the bottom chamber 8. An interception and adsorption mechanism is set inside the bottom chamber 8, such as... Figure 2 As shown, the oscillating assembly is located on the upper side of the scrubbing tower 1. The oscillating assembly includes a vertical plate 101, a rotating shaft 102, a transmission cam 103, and a transmission frame 104. The vertical plate 101 is installed on the upper side of the scrubbing tower 1. Two rotating shafts 102 are rotatably mounted on one side of the vertical plate 101. A driving component for driving the rotating shafts 102 to rotate is provided on the vertical plate 101. The driving component is a reciprocating motor. The two reciprocating motors are electrically connected to a controller via wires, so the two reciprocating motors can rotate synchronously. The transmission cam 103 is installed on the rotating shaft 102. The transmission frame 104 is installed on the upper side of the transmission rod 5 and covers the outside of the transmission cam 103. Figure 4 As shown, the buffer return mechanism includes an arc-shaped rod 201, a pressing block 202, a sleeve 203, a limiting rod 204, and a return spring 205. The arc-shaped rod 201 is installed on the inner wall of the scrubbing tower 1, the pressing block 202 is installed on the inner end of the arc-shaped rod 201, the sleeve 203 is sleeved on the arc-shaped rod 201 and the pressing block 202, the upper side of the sleeve 203 is connected to the lower side of the receiving plate 7, the limiting rod 204 is installed on the inner top wall of the sleeve 203 and inserted into the arc-shaped rod 201 and the pressing block 202, and the return spring 205 is sleeved on the limiting rod 204. The two ends of the return spring 205 are respectively connected to the sleeve 203 and the pressing block 202. Figure 5 As shown, the interception and adsorption mechanism includes a mounting frame 301, an interception layer 302, and a heavy metal adsorption layer 303. The mounting frame 301 is inserted into the bottom chamber 8. The interception layer 302 is located at the top of the inner wall of the mounting frame 301, and the heavy metal adsorption layer 303 is located at the bottom of the inner wall of the mounting frame 301. The interception layer 302 is composed of multiple interception meshes, and the aperture of the multiple interception meshes decreases from top to bottom. The multiple interception meshes intercept magnesium slag together, which enhances the interception effect of the interception layer 302 on magnesium slag.

[0028] Working principle:

[0029] The staff connects the external pipeline to the external liquid supply equipment. The liquid supply equipment delivers the rinsing solution to the storage tank 3 through the external pipeline, and then sprays it out from multiple rinsing nozzles 4. Next, the staff adds the magnesium slag to be processed into the screw feed mechanism 2. The screw feed mechanism 2 transports the magnesium slag into the rinsing tower 1, where it falls onto the receiving plate 7. Under the impact force, the receiving plate 7 deflects around the mounting column 6, causing the sleeve 203 to deflect synchronously. The sleeve 203 and the extrusion block 202 compress the return spring 205. The impact force is buffered, and the magnesium slag rolls on multiple receiving plates 7. During the rolling process, the magnesium slag comes into contact with the rinsing liquid sprayed by the rinsing nozzle 4. The rinsing liquid removes the heavy metals in the magnesium slag. The treated magnesium slag and rinsing liquid enter the mounting frame 301 inside the bottom silo 8. The interception layer 302 in the mounting frame 301 intercepts the magnesium slag, and the heavy metal adsorption layer 303 in the mounting frame 301 adsorbs the heavy metals in the rinsing liquid. The separated rinsing liquid is transported to the storage tank through an external pipeline, realizing the dynamic rinsing removal of heavy metals in the magnesium slag.
