[0002] A large amount of iron ore and kaolin is contained in manganese ore, in the process of sulfuric acid leaching of the manganese ore, iron and aluminum in the ore can be dissolved into the solution, and heavy metal ions such as zinc, copper and lead can also be dissolved into the sulfuric acid leaching solution along with the ore, the existence of the metal ions can seriously affect the deposition of electrolytic manganese, and cause the current efficiency to decrease, so the metal impurities need to be removed; in the impurity removal process taking manganese fluoride as a precipitant, the impurity removal rate can reach more than 97%, the purification and impurity removal effect is obvious, when the impurity is removed by using the method, the amount of MnF2 is 1.2 times of the theoretical amount, the MnF2 is stirred into a slurry before feeding, then half of the amount is added into the reaction system, and the other half is added after one hour of reaction, so that the precipitation rate of magnesium ions is improved.

[0004] When the existing manganese ore impurity removal equipment including the above patent removes impurities by using the impurity removal process taking manganese fluoride as a precipitant, there is a risk of generating toxic HF gas in the reaction process, so the impurity removal reaction needs to be carried out in a completely closed tank, which leads to the fact that MnF2 needs to be put into the inside of the reaction device first, and the first and second feeding can be carried out only after the reaction device is completely closed. However, the existing impurity removal equipment including the above patent cannot put MnF2 in two times and equal amounts, which can reduce the impurity removal efficiency, and even directly lead to the fact that the impurity removal effect does not meet the standard.

For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium.

[0032] like Figures 1 to 9As shown in the figure, an embodiment of the present invention provides a high-efficiency manganese ore impurity removal device, including a reaction tank 1. The reaction tank 1 is provided with a stirring mechanism for stirring materials, and the top of the reaction tank 1 is provided with a main feed inlet 11 and a secondary feed inlet 12. The reaction tank 1 is provided with a feeding hopper 2 for temporarily storing precipitant. The feeding hopper 2 is provided corresponding to the secondary feed inlet 12. The feeding hopper 2 is provided with a baffle 3. The baffle 3 is driven to divide the precipitant in the feeding hopper 2 into two halves of equal volume so that the precipitant can be added in two equal amounts.

[0033] Specifically, this impurity removal mechanism is used for removing impurities from the manganese sulfate leaching solution (hereinafter referred to as the material), and its main structure is reaction tank 1, such as... Figure 1 and Figure 2 As shown, the reaction tank 1 is equipped with a stirring mechanism and a feeding hopper 2. The top of the reaction tank 1 has a main feed inlet 11 and a secondary feed inlet 12. The main feed inlet 11 is used for feeding materials, while the secondary feed inlet 12 is used for batch feeding of the precipitant (MnF2 powder mixed with pure water to form a slurry). The feeding hopper 2 is installed at the top of the reaction tank 1 and is located directly below the secondary feed inlet 12, so that all the precipitant fed through the secondary feed inlet 12 can enter the feeding hopper 2. The feeding hopper 2 is internally equipped with a baffle 3. Optionally, the feeding hopper 2 is a vertically placed cylinder with a closed bottom. The baffle 3 is positioned along the central axis of the cylinder, and its width is equal to the inner diameter of the cylinder. The baffle 3 is driven to move along the axial direction of the cylinder and contact the bottom of the cylinder. When the baffle 3 is driven to contact the bottom of the cylinder, the precipitant added inside the cylinder is divided into two equal volumes. It should be noted that, in order to ensure that the precipitant is added through the auxiliary feed inlet 12... When the precipitant is added to the hopper 2, it can be directly divided into two equal parts by the partition 3. The length of the partition 3 is less than the length of the cylinder, and when the partition 3 is in the initial position, its lower end is a certain distance from the bottom inner wall of the cylinder, so that the space on both sides of the lower part of the cylinder can be connected (the partition 3 and the cylinder form a communicating vessel). After the precipitant is added, once the precipitant has stabilized (no longer fluctuating), the partition 3 is driven to move vertically downwards until it contacts the bottom of the cylinder. At this time, the precipitant in the cylinder will be divided into two equal parts. The use of a linear drive mechanism to drive a plate to move vertically is existing technology and can be directly applied without further explanation. In addition, in order to allow the precipitant in the hopper 2 to be added in batches, the bottom of the cylinder is provided with discharge ports on both sides of the partition 3. Correspondingly, each discharge port is only equipped with an electric control valve. It should be noted that after the partition 3 is driven to contact the bottom inner wall of the cylinder, the upper part of the partition 3 is still higher than the liquid level of the precipitant.

[0034] When using this impurity removal equipment, keep the baffle 3 in the initial position mentioned above. First, feed the material into the reaction tank 1 through the main feed port 11, and then feed the precipitant into the feeding hopper 2 through the auxiliary feed port 12. After the precipitant stabilizes, drive the baffle 3 down to contact the bottom inner wall of the feeding hopper 2. At this time, the precipitant is divided into two equal halves by the baffle 3. After closing the main feed port 11 and the auxiliary feed port 12, open the electric control valve corresponding to one set of discharge ports to feed the precipitant on the corresponding side of the cylinder into the material. With the stirring of the stirring mechanism, the two are fully mixed. After the reaction has been going on for one hour, open the electric control valve corresponding to the other set of discharge ports to add the remaining half of the precipitant in the feeding hopper 2 into the material, and continue stirring until the reaction is completed.

[0035] The impurity removal device provided in this embodiment of the invention, by setting a feeding hopper 2 inside the reaction tank 1, allows all the catalyst to be temporarily stored in the feeding hopper 2 before the reaction begins. The feeding hopper 2 and the baffle 3 inside it form a communicating vessel, so that the precipitate can be naturally divided into two parts of equal volume after being added into the feeding hopper 2. Then, by driving the baffle 3 to move, the two parts of precipitate are completely separated. This can shorten the preparation time and, while ensuring that the reaction tank 1 is in a closed state, the precipitate in the feeding hopper 2 can be added in two equal amounts, ensuring the impurity removal efficiency and avoiding the impurity removal effect not meeting the standard.

[0036] Furthermore, the feeding hopper 2 is half of a cylinder, and the inner cavity of the feeding hopper 2 is also half of a semi-cylindrical section. The feeding hopper 2 is horizontally and rotatably installed inside the reaction vessel 1, and the feeding hopper 2 is driven to swing around its own central axis.

[0037] Specifically, in the above embodiment, the feeding hopper 2 is a vertically placed cylinder, and two sets of discharge ports are provided at its lower part to achieve two feedings. A large amount of material easily remains on the inner wall of the feeding hopper 2, resulting in a smaller actual amount participating in the reaction. Furthermore, the residual material will also affect the dosage in the next batch of production, and the location of the electrically controlled valve is inconvenient for cleaning. In this embodiment, such as... Figure 3 , Figure 4 and Figure 7 As shown, the feeding hopper 2 is a semi-cylinder, and has an inner cavity coaxial with it and also semi-cylinder in shape. The feeding hopper 2 is horizontally positioned and rotatably mounted inside the reaction vessel 1 near the top. The feeding hopper 2 is driven to swing around its own central axis. Furthermore, in this embodiment, the partition 3 is still vertically positioned. The horizontal dimension of the partition 3 is equal to the horizontal dimension of the inner cavity of the feeding hopper 2. The lower part of the partition 3 in the direction of gravity is adapted to the inner wall of the feeding hopper 2, and the partition 3 is driven to move radially, i.e., vertically, along the feeding hopper 2. During the movement of the partition 3, it has a first state and a second state relative to the feeding hopper 2.

[0038] In the first state, only the two ends of the partition 3 in the horizontal direction are in contact with the inner wall of the feeding hopper 2, while the lower part of the partition 3 in the direction of gravity is not in contact with the inner wall of the feeding hopper 2. This state corresponds to the initial state mentioned above.

[0039] In the second state, the two ends of the baffle 3 in the horizontal direction and the lower part in the gravity direction are in contact with the inner wall of the feeding hopper 2, so that the baffle 3 can separate the precipitant in the feeding hopper 2 into two parts of equal volume.

[0040] Before adding the precipitant to the feeding hopper 2 through the auxiliary feed inlet 12, the baffle 3 is moved to the first state. After all the precipitant has been added to the feeding hopper 2 and the precipitant has stabilized, the baffle 3 is moved down to the second state. Unlike the previous embodiment, when the precipitant in the feeding hopper 2 is added to the material in the reaction tank 1 in portions, the baffle 3 is kept in the second state, and the feeding hopper 2 is swung 90° to one side of its central axis. If it swings to the left of the baffle 3, the feeding hopper... The precipitant on the right side of the inner baffle 3 will be poured downwards from the opening of the feeding hopper 2. With this configuration, since the baffle 3 is in contact with the inner wall of the feeding hopper 2 when it is in the second state, while ensuring that the material is fed in batches, the relative movement between the baffle 3 and the feeding hopper 2 can scrape off the precipitant on the inner wall of the feeding hopper 2, thereby reducing the precipitant residue on the inner wall of the feeding hopper 2. During the second feeding, the feeding hopper 2 swings 180 degrees in the opposite direction from the position after the first swing, so that the remaining precipitant can be poured into the material.

[0041] Furthermore, the partition 3 is rotatably connected to the inner wall of the reaction vessel 1, and the partition 3 is driven to swing around the central axis of the feeding hopper 2.

[0042] Specifically, since MnF2 is slightly soluble in water, and the second addition of the precipitant requires waiting for one hour, prolonged standing will cause MnF2 to precipitate, making it difficult to flow and leaving a large amount of residue inside the feeding hopper 2. In this embodiment, the baffle 3 is rotatably connected to the inner wall of the reaction tank 1, and the baffle 3 is rotatably installed inside the feeding hopper 2. That is, the baffle 3 can move up and down in the vertical direction to adjust its distance from the bottom inner wall of the feeding hopper 2. At the same time, the baffle 3 can also swing around the central axis of the feeding hopper 2 to stir the remaining precipitant in the feeding hopper 2. When the baffle 3 is in the second state, the rotation axis of the baffle 3 coincides with the central axis of the feeding hopper 2.

[0043] After the precipitant is added for the first time, the feeding hopper 2 is driven to swing back to its initial position. At this time, the opening of the feeding hopper 2 is facing upward and in a horizontal state. The angle of the feeding hopper 2 is kept unchanged, and the baffle 3 is adjusted to the first state mentioned above. Then, the baffle 3 is driven to swing around the central axis of the feeding hopper 2. Assuming that the vertical position of the baffle 3 is 0°, the baffle 3 swings in the range of -90° to 90° to stir the remaining half of the precipitant in the feeding hopper 2 to prevent precipitation. The use of a linear drive mechanism in conjunction with a rotary drive mechanism to realize the vertical movement and rotation of the baffle 3 is existing technology. Similarly, the use of a rotary drive mechanism to drive the swing of the feeding hopper 2 is also existing technology and can be directly applied without further explanation.

[0044] In another embodiment of the present invention, the partition 3 includes a first plate 31 and a second plate 32. The second plate 32 is slidably installed on the inner side of the first plate 31. A third plate 33 is movably installed at both ends of the second plate 32. The second plate 32 is driven to move vertically to contact the inner wall of the feeding hopper 2, and the third plate 33 is driven to move horizontally to contact the inner wall of the feeding hopper 2.

[0045] Specifically, after the precipitant is added to the material for the first time, the baffle 3 in its first state needs to be continuously oscillated to prevent the remaining precipitant in the feeding hopper 2 from settling. When the baffle 3 is in its first state, both ends of it are in contact with the inner wall of the feeding hopper 2 in the horizontal direction. Prolonged oscillation will cause wear at the contact points between the baffle 3 and the feeding hopper 2, resulting in the baffle 3 being unable to completely separate the precipitant in the feeding hopper 2 into two parts even when in its second state. In this embodiment, as... Figure 5 and Figure 6 As shown, the partition 3 includes a first plate 31 and a second plate 32. Both the first plate 31 and the second plate 32 are rectangular, and the second plate 32 is slidably installed on the inner side of the first plate 31. Figure 6 As shown, both ends of the second plate 32 protrude beyond the first plate 31, and the second plate 32 is driven to move radially along the feeding hopper 2 and can extend from the lower part of the first plate 31. A third plate 33 is movably mounted on both ends of the second plate 32. For ease of description, it is referred to as... Figure 5 For example, a view Figure 5 The horizontal direction is the length direction of the inner cavity of the feeding hopper 2, the first plate 31, the second plate 32 and the third plate 33, and the vertical direction is the width direction of the first plate 31, the second plate 32 and the third plate 33. The lengths of the first plate 31 and the second plate 32 are both less than the length of the inner cavity of the feeding hopper 2. The lower end of the third plate 33 in the direction of gravity is flush with the lower end of the second plate 32 in the direction of gravity, so as to avoid the partition 3 not completely separating the lower inner cavity of the feeding hopper 2.

[0046] Unlike the above embodiments, in this embodiment, when the partition 3 is in the first state, the third plate 33 is retracted inside the second plate 32, and the second plate 32 is retracted inside the first plate 31, that is, none of the parts of the partition 3 are in contact with the inner wall of the feeding hopper 2; while when the partition 3 is in the second state, the second plate 32 extends outward from the lower end of the first plate 31 and contacts the inner wall of the feeding hopper 2, and the two third plates 33 extend outward from the left and right ends of the second plate 32 respectively and contact the inner walls of the two ends of the feeding hopper 2, thereby dividing the lower part of the inner cavity of the feeding hopper 2.

[0047] With this configuration, when the partition 3 is driven to swing, it is in the first state, and there is no friction between any part of the partition 3 and the inner wall of the feeding hopper 2. This reduces the resistance when the partition 3 swings and ensures the separation effect when the partition 3 is in the second state. Using a linear drive mechanism to move the third plate 33 along the length of the second plate 32 is existing technology. Similarly, using a linear drive mechanism to move the second plate 32 along the width of the first plate 31 is also an existing technology. Figure 5 The vertical movement shown in the view is existing technology and can be applied directly without further explanation; obviously, in order to ensure the separation effect of the partition 3 on the inner cavity of the feeding hopper 2, the second plate 32 and each third plate 33 are provided with rubber pads on the side that contacts the inner wall of the feeding hopper 2. The rubber pads are made of fluororubber.

[0048] In another embodiment of the present invention, the reaction vessel 1 is provided with an adjustment mechanism 5 that drives the first plate 31 to move radially along the feeding hopper 2. While the adjustment mechanism 5 drives the first plate 31 to move toward the inner wall of the feeding hopper 2, it can also lock the partition 3 so that it cannot rotate.

[0049] Specifically, in the above embodiment, the first and second additions of the precipitant are achieved by driving the hopper 2 to swing. During the swinging process of the hopper 2, the baffle 3 must remain in the second state and must be vertical and not rotate. Once the baffle 3 rotates, the precipitant that needs to be retained in the hopper 2 for the second addition will be poured out prematurely because the angle between the baffle 3 and the horizontal direction becomes smaller. When the baffle 3 is in the second state, the second plate 32 and the third plate 33 are in close contact with the inner wall of the hopper 2. The friction between the second plate 32 and the third plate 33 and the inner wall of the hopper 2 may cause the baffle 3 to swing along with the hopper 2. In this embodiment, the reaction tank 1 is equipped with an adjustment mechanism 5. The adjusting mechanism 5 can drive the first plate 31 to move towards the inner wall of the feeding hopper 2, and the adjusting mechanism 5 can also lock the partition 3 in the second state so that it cannot rotate; optionally, two sets of connecting rods 4 are vertically fixed to the top of the reaction tank 1, and the two ends of the first plate 31 are rotatably connected to the lower ends of the corresponding connecting rods 4 through the first rotating shaft 311. The adjusting mechanism 5 includes a slider 51 slidably installed on the lower end of the connecting rod 4, and a connecting block 321 is fixedly connected to the second plate 32. The connecting block 321 is rotatably connected to the slider 51 through the second rotating shaft 322. The slider 51 is driven to slide in the vertical direction, wherein the first rotating shaft 311 is rotatably connected to the opposite side of the two connecting rods 4, while the slider 51 is slidably installed on the opposite side of the two connecting rods 4. Figure 5 As shown, with this configuration, during the sliding stroke of slider 51, there is a height that allows the first rotating shaft 311 and the second rotating shaft 322 to be coaxial. At this height, the partition 3 is in the first state, that is... Figure 5 In the state shown, the first plate 31 is driven to swing by the first rotating shaft 311, which in turn drives the second plate 32 to swing synchronously. However, when the first rotating shaft 311 and the second rotating shaft 322 are misaligned, since the first plate 31 can only rotate around the central axis of the first rotating shaft 311, and the second plate 32 can only rotate around the central axis of the second rotating shaft 322, and since the second plate 32 is slidably installed inside the first plate 31, if the second plate 32 is to rotate around the central axis of the first rotating shaft 311, then the second rotating shaft 322 also needs to rotate around the first rotating shaft 311. The rotating shaft 322 is restricted by the slider 51 and cannot move (at this time, the position of the slider 51 is determined). Therefore, the second plate 32 cannot rotate with the first plate 31. Similarly, the first plate 31 cannot rotate with the second plate 32. Therefore, when the first rotating shaft 311 and the second rotating shaft 322 are not on the same axis, the partition 3 will be locked and cannot rotate. With this setting, while adjusting the position of the second plate 32 relative to the first plate 31, the partition 3 is locked when it is not in the first state, thereby ensuring that when the feeding hopper 2 swings (the partition 3 is in the second state), the partition 3 will not swing with the feeding hopper 2.

[0050] Furthermore, a fixing block 41 is fixedly connected to the lower part of the connecting rod 4. The feeding hopper 2 is rotatably connected to the fixing block 41 via a third rotating shaft 21. A first groove 211 is provided on the third rotating shaft 21, and a second groove 411 is provided on the fixing block 41. An adjusting block 323 is rotatably connected to the side of the connecting block 321 away from the second rotating shaft 322. A locking block 324 is fixedly connected to the adjusting block 323. The locking block 324 can be adapted to the first groove 211 and the second groove 411. When the first rotating shaft 311 and the second rotating shaft 322 are coaxial, the locking block 324 simultaneously engages with the first groove 211 and the second groove 411.

[0051] Specifically, when the baffle 3 is driven to swing and stir the precipitant in the feeding hopper 2, the shaking of the precipitant will cause the feeding hopper 2 to sway. In this embodiment, a fixing block 41 is fixedly connected to the lower end of the connecting rod 4, such as... Figure 5 , Figure 8 and Figure 9 As shown, the fixing block 41 includes a horizontal part and a vertical part that are connected to each other. Figure 5In the middle section, the horizontal part of the fixed block 41 is the horizontal part, and the vertical part is the vertical part. The horizontal part is fixedly connected to the lower part of the connecting rod 4. The feeding hopper 2 is rotatably connected to the fixed block 41 via the third rotating shaft 21, so that the feeding hopper 2 is also rotatably mounted on the connecting rod 4. An adjusting block 323 is rotatably connected to the side of the connecting block 321 away from the second rotating shaft 322. A locking block 324 is fixedly connected to the adjusting block 323. The third rotating shaft 21 passes through the vertical part, and a first groove 211 is opened on the third rotating shaft 21. When the feeding hopper... When the opening is at an angle, the first groove 211 is distributed vertically, and the vertical part of the fixing block 41 has a second groove 411. The widths of the first groove 211 and the second groove 411 are equal and they are connected to each other. The vertical dimension of the locking block 324 is larger than the length of the first groove 211, so that the locking block 324 can cooperate with both the first groove 211 and the second groove 411 at the same time. At this time, the third rotating shaft 21 is locked by the locking block 324 and cannot rotate. When the slider 51 is driven to slide, it can be moved through... The second rotating shaft 322 drives the connecting block 321 to move synchronously, thereby causing the second plate 32 to move relative to the first plate 31. Simultaneously, the connecting block 321 drives the adjusting block 323, which is rotatably connected to it, to move synchronously. The adjusting block 323 then drives the locking block 324 to slide in the first groove 211 and the second groove 411, or slide alone in the second groove 411. During the sliding stroke of the slider 51, when the first rotating shaft 311 and the second rotating shaft 322 are coaxial, the locking block 324 simultaneously slides in the first groove 211 and the second groove 411. In this configuration, the locking block 324 restricts the third rotating shaft 21 from rotating. This passive locking of the third rotating shaft 21 ensures that when the partition 3 can rotate (when the first rotating shaft 311 and the second rotating shaft 322 are coaxial), the feeding hopper 2 (third rotating shaft 21) cannot rotate. Conversely, when the partition 3 is locked, the feeding hopper 2 can be driven to rotate. This ensures that when the partition 3 is driven to swing, the feeding hopper 2 is always locked, and when the feeding hopper 2 is driven to swing, the partition 3 is always locked.

[0052] In another embodiment of the present invention, the adjustment mechanism 5 further includes an electric push rod 52 fixed to the top of the reaction vessel 1. The electric push rod 52 is vertically arranged and drives the slider 51 to slide in the vertical direction.

[0053] Furthermore, the electric push rod 52 is connected to the slider 51 via the suction mechanism 6. The second plate 32 is provided with an ejector assembly. When the electric push rod 52 extends, it first causes the slider 51 to slide downward along the connecting rod 4, and then the suction mechanism 6 drives the ejector assembly to move so as to drive the third plate 33 to extend outward from the second plate 32.

[0054] Specifically, in the above embodiments, linear drive mechanisms need to be set for each third plate 33, which is complex. Furthermore, since the second plate 32 needs to slide relative to the first plate 31, the linear drive mechanism that drives the third plate 33 to extend needs to be installed on the second plate 32 (otherwise interference will occur). This complex structure makes maintenance of the linear drive mechanism inconvenient. In this embodiment, the adjustment mechanism 5 includes an electric push rod 52 fixed to the top of the reaction vessel 1. The electric push rod 52 is vertically positioned and can drive the slider 51 to slide vertically, that is, drive the slider 51 to slide vertically on the connecting rod 4. The output end of the electric push rod 52 is connected to… A suction mechanism 6 is provided, comprising a first piston rod 61, a piston cylinder 62, and a first piston block 63, as shown in the figure. The first piston block 63 is fixedly connected to the upper end of the first piston rod 61 and is located inside the piston cylinder 62. The first piston block 63 and the piston cylinder 62 are dynamically sealed together. Preferably, a spring 64 is provided inside the piston cylinder 62, which can increase the resistance to the movement of the first piston block 63 relative to the piston cylinder 62. The lower end of the first piston rod 61 passes through the fixing block 41 (horizontal part) and is fixedly connected to the adjusting block 323. The output end of the electric push rod 52 is fixedly connected to the piston cylinder 62. An ejection assembly is also provided inside the second plate 32, such as... Figure 5 As shown, the ejection assembly includes a second piston block 325 horizontally disposed within the second plate 32, a second piston rod 326 fixedly connected to the second piston block 325, and a piston cavity 327 formed on the second plate 32 to cooperate with the second piston block 325. The second piston block 325 is dynamically and sealingly installed in the piston cavity 327, while the second piston rod 326 is fixedly connected to the third plate 33. In addition, a first vent 611 is formed in the first piston rod 61, the upper end of the first vent 611 penetrates through the first piston block 63 and communicates with the inner cavity of the piston cylinder 62, and a second vent 3211 is formed in the connecting block 321. The upper end of the second vent 3211 is connected to the lower end of the first vent 611 through a pipe 65, while the lower end of the second vent 3211 penetrates through the connecting block 321 and communicates with the interior of the second plate 32 and the piston cavity 327 within the second plate 32.

[0055] With this configuration, when the electric push rod 52 extends to drive the piston cylinder 62 downward, it is restricted by the spring 64. The piston cylinder 62 initially remains relatively stationary with the first piston rod 61, allowing the first piston rod 61 to push the connecting block 321 downward via the adjusting block 323. The connecting block 321 then drives the slider 51 to slide vertically downward on the connecting rod 4 via the second rotating shaft 322. Simultaneously, the connecting block 321 drives the second plate 32 to move synchronously, causing the second plate 32 to slide relative to the first plate 31 until the second plate 32 contacts the inner wall of the feeding hopper 2. At this point, the second plate 32 can no longer move, and correspondingly, the connecting block 321, the second rotating shaft 322, the slider 51, and the adjusting block 323 cannot move downward, thus preventing the first piston rod 61 from moving downward. At this point, the electric push rod 52 continues to extend and pushes the piston cylinder 62 downward, causing relative movement between the piston cylinder 62 and the first piston rod 61, thereby releasing the gas inside the piston cylinder 62. Squeezed into the piston chamber 327, as the air pressure in the piston chamber 327 increases, the second piston block 325 slides in the piston chamber 327, thereby driving the second piston rod 326 to push the third plate 33 outward until the third plate 33 contacts the inner wall of the feeding hopper 2. In this embodiment, when the electric push rod 52 extends, it is restricted by the spring 64. The relative movement of the piston cylinder 62 and the first piston block 63 needs to overcome a large resistance, so that when the electric push rod 52 extends, it can first cause the second plate 32 to slide relative to the first plate 31, and then drive the third plate 33 to extend outward from the second plate 32, so as to avoid the third plate 33 extending outward and contacting the feeding hopper 2 first, resulting in wear. Conversely, when the electric push rod 52 shortens, it will drive the third plate 33 to retract into the second plate 32, and will also drive the second plate 32 to slide in the opposite direction on the first plate 31. The retraction of the third plate 33 and the reverse sliding of the first plate 31 are not sequential (either one is fine).

[0056] In another embodiment of the present invention, the stirring mechanism includes a stirring shaft 13 rotatably mounted in the reaction vessel 1, a first stirring blade 131 fixedly connected to the middle part of the stirring shaft 13, a second stirring blade 132 fixedly connected to the lower part of the stirring shaft 13, and the second stirring blade 132 being adapted to the lower inner cavity of the reaction vessel 1.

[0057] Specifically, the stirring mechanism includes a stirring shaft 13 and a first stirring blade 131 and a second stirring blade 132 mounted on the stirring shaft 13. The stirring shaft 13 is driven to rotate and causes the first stirring blade 131 and the second stirring blade 132 to revolve around the central axis of the stirring shaft 13. The first stirring blade 131 is used to stir the area in the middle of the reaction tank 1, while the second stirring blade 132 is used to stir the area at the bottom of the reaction tank 1, thereby ensuring that the material can be fully mixed with the precipitant. The bottom of the reaction tank 1 is also provided with a discharge hole, which is used to discharge the solid-liquid mixture after the reaction to the outside, so as to facilitate solid-liquid separation by using a filter press or by sedimentation.

[0058] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
