Description

Technical Field

[0001] This invention relates to the field of manganese ore impurity removal technology, and specifically discloses a manganese sulfate leaching solution impurity removal device. Background Technology

[0002] Electrolytic manganese dioxide is mainly used in the battery and new energy industries. It is a key raw material for manufacturing high-power, high-discharge dry batteries, power batteries, and magnetic materials and components for the electronics industry. According to the different raw materials, it can be divided into manganese carbonate ore method, manganese oxide reduction roasting method, and two-ore method. All three methods involve leaching and purification (impurity removal) processes. Regardless of the method, multiple samples need to be taken during the leaching process to detect the manganese and acid content in the solution, and the amount of feed should be adjusted appropriately according to the test results.

[0003] For example, the invention patent with announcement number CN118067461B and announcement date of 2024-07-23 discloses a sampling device for detecting a mixed liquid, including several sampling parts arranged vertically on a tank. Each sampling part includes: a first sleeve fixedly connected to the tank, the first sleeve having a hollow internal structure; a sealing block slidably connected to the tank, the tank having a through hole corresponding to the sealing block; a trigger block slidably and sealingly connected to the interior of the first sleeve, the stepped structure being able to abut against the sealing block; and a force-applying block drivingly connected to the trigger block, the center of the force-applying block being slidably connected to an adjusting rod, the end of the adjusting rod being spherically connected to the trigger block.

[0004] For example, the invention patent with announcement number CN117258639B and announcement date of 2024-04-23 discloses a mixing device with sampling and detection function, including: a mixing tank; a mixing mechanism, which is disposed on the mixing tank and used to mix the raw materials inside the mixing tank; a reflux mechanism, which is disposed on the side of the tank and used to guide the raw materials at the bottom of the tank back to the top of the tank, and the mixing mechanism has a spiral blade at one end extending into the reflux mechanism to push the raw materials into the reflux mechanism during the mixing process; and a sampling and detection mechanism, which is disposed on the reflux mechanism and includes an actuating wheel and a drain pipe passing through the actuating wheel.

[0005] Both of the above methods can be used for sampling in the manganese sulfate leaching process. However, when the former is used, some of the material that remains in the pipeline cannot be mixed with other materials, and is not representative and needs to be discarded. This method is inconvenient to operate and causes some loss of material. Although the latter method reduces the loss of solution to a certain extent, the material in the circulation section cannot be mixed with other materials in time, which will reduce the mixing effect and make it inconvenient to clean the device. Summary of the Invention

[0006] The purpose of this invention is to provide a device for removing impurities from manganese sulfate leaching solution.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] A manganese sulfate leaching solution impurity removal device includes a tank body, a stirring assembly inside the tank body, and several sampling assemblies on the side of the tank body. Each sampling assembly includes a sampling tube with one end penetrating into the tank body. The portion of the sampling tube outside the tank body has a discharge port. A baffle is installed inside the sampling tube, and the baffle is driven to move along the axial direction of the sampling tube.

[0009] In the aforementioned impurity removal device, the sampling tube extends from one end inside the tank towards the central axis of the tank.

[0010] In the aforementioned impurity removal device, the sampling tube is driven to move radially along the tank, and the sampling tube has an initial position where one end is flush with the inner wall of the tank.

[0011] The aforementioned impurity removal device has a driving component on the side wall of the tank corresponding to the sampling tube. The driving component drives the sampling tube and the stop block to move synchronously or relative to each other. A limiting component is provided on the tank to restrict the position of the sampling tube.

[0012] The aforementioned impurity removal device includes a drive assembly comprising a drive unit and an adjustment unit. The adjustment unit includes an adjustment rod that extends through the sampling tube and is fixedly connected to a stop block. A first spring is fitted onto the portion of the adjustment rod outside the sampling tube.

[0013] The aforementioned impurity removal device includes a limiting component consisting of a sleeve fixed to the tank body, the sleeve being fitted over the outside of the sampling tube, a guide tube fixed to the sampling tube at the position corresponding to the discharge port, a guide groove adapted to the guide tube being provided on the sleeve, and an elastic element being provided at the end of the side wall of the guide groove away from the tank body.

[0014] The aforementioned impurity removal device includes a sliding block inside the sampling tube, an adjusting rod passing through the middle of the sliding block, a second spring inside the sampling tube to maintain the relative position of the sliding block and the sampling tube, and a compensation cavity separated by the sliding block inside the sampling tube, which is connected to the outside of the sampling tube.

[0015] The aforementioned impurity removal device has a blocking position and an open position during the sliding stroke of the sliding block in the sampling tube. A locking element is also provided in the sampling tube to lock the sliding block in the open position.

[0016] The aforementioned impurity removal device includes a locking pin that extends radially through the sampling tube, a sliding block with a insertion hole for engaging the locking pin, a wedge-shaped end of the locking pin engaging with the sliding block, and a third spring on the outer wall of the sampling tube to maintain the relative position of the locking pin and the sampling tube.

[0017] The aforementioned impurity removal device includes a stirring assembly comprising a stirring shaft rotatably mounted inside a tank, a plurality of stirring blades fixedly connected to the stirring shaft, a drive motor mounted on the top of the tank, and the upper end of the stirring shaft extending through to the outside of the tank and being connected to the drive motor for transmission.

[0018] In the above technical solution, the leachate impurity removal device provided by the present invention, by setting a baffle in the sampling tube and making the baffle dynamically seal with the sampling tube, when not sampling, the baffle can prevent the solution from entering the sampling tube, thus avoiding the solution from remaining in the pipe and being unable to mix with other solutions. When sampling, it can ensure that the solution volume of each sample is equal, and since the solution is pushed out by the movement of the baffle in the sampling tube, the residual solution on the inner wall of the sampling tube can be reduced, thereby reducing the error of subsequent sampling and detection results.

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. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0031] like Figures 1 to 7 As shown in the figure, the manganese sulfate leaching solution impurity removal device provided in the embodiment of the present invention includes a tank 1, a stirring assembly 2 is provided inside the tank 1, and a plurality of sampling assemblies 3 are provided on the side of the tank 1. Each sampling assembly 3 includes a sampling tube 31 with one end penetrating into the tank 1. The part of the sampling tube 31 outside the tank 1 is provided with a discharge port 311. A baffle 32 is provided inside the sampling tube 31. The baffle 32 is driven to move along the axial direction of the sampling tube 31.

[0032] Specifically, such as Figure 1 and Figure 2As shown, the main structure of the impurity removal device for the leachate is a tank 1, which is arranged vertically. A feed pipe 11 is installed at the top of the tank 1, and a sealing cap is installed at the top of the tank corresponding to the feed pipe 11. Several feed pipes for adding impurity removal reagents are also provided at the top of the tank. A discharge pipe 12 is installed at the bottom of the tank 1, connecting to the interior of the tank 1. A stirring assembly 2 is installed inside the tank 1 to stir the solution and ensure thorough mixing of the components. Several sampling components 3 are installed on the side of the tank 1. Figure 1 The sampling assembly 3 is provided in three sets. Each sampling assembly 3 includes a sampling tube 31, one end of which is connected to the interior of the tank 1. Each sampling tube 31 is arranged radially along the tank 1 and at equal intervals along the side wall of the tank 1 to sample solutions at different heights within the tank 1. The sampling assembly 3 also includes a baffle 32 disposed within the sampling tube 31. The baffle 32 is circular and its size is adapted to the inner cavity of the sampling tube 31. The baffle 32 is dynamically sealed to the sampling tube 31 and can move axially along the sampling tube 31 when driven. Optionally, the outer wall of the tank 1 has corresponding baffles 32. A linear drive mechanism is provided to drive the stop block 32 to move along the axis of the sampling tube 31. This is existing technology and can be directly applied without further explanation. The part of the sampling tube 31 outside the tank body 1 is provided with a discharge port 311. In this embodiment, a solenoid valve is provided at the discharge port 311. Since the sampling tubes 31 are all arranged horizontally, preferably, the discharge port 311 is opened on the side wall of the sampling tube 31 near its end. The end of the sampling tube 31 outside the tank body 1 is closed, and the discharge port 311 is opened on the side wall of the sampling tube 31, and the opening of the discharge port 311 is vertically downward.

[0033] During the stroke of the stop block 32 moving axially along the sampling tube 31, it has at least a first position, a second position, and a third position relative to the sampling tube 31:

[0034] When in the first position, the baffle 32 is outside the sampling tube 31 and inside the tank 1. At this time, the end of the sampling tube 31 corresponding to the inside of the tank 1 is in an open state, and the solution in the tank 1 can enter the sampling tube 31 through the end of the sampling tube 31 inside the tank 1. When the baffle 32 is in this position, the solenoid valve at the outlet 311 is in a closed state.

[0035] When in the second position, the baffle 32 is inside the sampling tube 31. At this time, the baffle 32 blocks one end of the sampling tube 31 corresponding to the inside of the tank 1, and the solution in the tank 1 cannot enter the sampling tube 31. The inner cavity of the sampling tube 31 and the inner cavity of the tank 1 are separated by the baffle 32.

[0036] When in the third position, the stop block 32 is located inside the sampling tube 31 near the outlet 311. In this position, the space enclosed by the tube body of the sampling tube 31 and the stop block 32 is the smallest.

[0037] During normal stirring of the solution in tank 1, baffle 32 remains in the second position, and the solenoid valve is closed. When sampling is required, the solenoid valve remains closed, and baffle 32 is driven to move axially along the sampling tube 31, adjusting baffle 32 from the second position to the first position. At this time, the solution in tank 1 enters the sampling tube 31 from the end of the sampling tube 31. After the space inside the sampling tube 31 is completely filled, baffle 32 is driven to move in the opposite direction from the first position to the second position. At this time, the solution in the sampling tube 31 is separated from the solution in tank 1. The solenoid valve is opened, and baffle 32 is driven to move from the second position to the third position. The movement of baffle 32 completely pushes the solution in the sampling tube 31 to the outlet 311 for discharge.

[0038] The leachate impurity removal device provided in this embodiment of the invention, by setting a baffle 32 in the sampling tube 31 and making the baffle 32 dynamically seal with the sampling tube 31, can prevent the solution from entering the sampling tube 31 when no sample is being taken, thus avoiding the solution from remaining in the pipe and being unable to mix with other solutions. During sampling, it can ensure that the volume of solution sampled each time is equal. Moreover, since the solution is pushed out by the movement of the baffle 32 in the sampling tube 31, the residual solution on the inner wall of the sampling tube 31 can be reduced, thereby reducing the error of subsequent sampling and detection results.

[0039] Furthermore, the sampling tube 31 extends from one end inside the tank 1 toward the central axis of the tank 1.

[0040] Specifically, when the stirring assembly 2 stirs the solution in the tank 1, the fluid velocity near the inner wall of the tank 1 drops sharply, even approaching zero, due to the frictional resistance of the wall and the boundary layer effect. The solution at this location is not representative as a test sample, which will lead to increased error. In this embodiment, the sampling tube 31 extends from one end inside the tank 1 towards the central axis of the tank 1. That is, the end of the sampling tube 31 inside the tank 1 protrudes from the inner wall of the tank 1. When the baffle 32 is adjusted to the first position, the solution entering the sampling tube 31 is always the liquid near the end of the sampling tube 31 inside the tank 1, thereby avoiding the solution near the inner wall of the tank 1 from being sampled and ensuring the accuracy of the sampling test results.

[0041] Furthermore, the sampling tube 31 is driven to move radially along the tank 1, and the sampling tube 31 has an initial position with one end flush with the inner wall of the tank 1.

[0042] Specifically, in the above embodiment, the end of the sampling tube 31 protrudes from the inner wall of the tank 1. This protrusion disrupts the core flow field and reduces mixing efficiency, and also causes solids to accumulate behind the tube, resulting in sampling distortion and dead zones. In this embodiment, the sampling tube 31 is movably mounted on the side wall of the tank 1, with a dynamic seal connection between the sampling tube 31 and the side wall of the tank 1. The side wall of the tank 1 is also equipped with another linear drive mechanism to propel the sampling tube 31 along its own axial direction. This configuration allows the sampling tube 31 to move axially outwards from the tank 1 when no sampling is required, until the end of the sampling tube 31 is flush with the inner wall of the tank 1. This avoids interference with the flow field during mixing within the tank 1. When sampling is needed... First, the sampling tube 31 is inserted into the tank 1, so that the inlet of the sampling tube 31 (the opening of the sampling tube 31 at one end inside the tank 1) is adjusted to a position away from the inner wall of the tank 1, so as to avoid the solution near the inner wall of the tank 1 being sampled. It should be noted that when the sampling tube 31 is inserted into the tank 1, the baffle 32 is driven to move synchronously with the sampling tube 31, thereby preventing the solution near the inner wall of the tank 1 from entering the sampling tube 31 in advance and being carried by the sampling tube 31 to the sampling position inside the tank 1, ensuring that all the sampled solution is fully stirred. After the baffle 32 pushes out all the solution in the sampling tube 31, the baffle 32 needs to be adjusted to the second position mentioned above to avoid the solution in the sampling tube 31 not being stirred.

[0043] In another embodiment of the present invention, a driving component 4 is provided on the side wall of the tank body 1 corresponding to the sampling tube 31. The driving component 4 drives the sampling tube 31 and the stop block 32 to move synchronously or relative to each other. A limiting component 5 is provided on the tank body 1 to limit the position of the sampling tube 31.

[0044] Furthermore, the drive assembly 4 includes a drive part and an adjustment part. The adjustment part includes an adjustment rod 41, which extends into the sampling tube 31 and is fixedly connected to the stop block 32. The portion of the adjustment rod 41 outside the sampling tube 31 is fitted with a first spring 411.

[0045] Optionally, the limiting component 5 includes a sleeve 51 fixed to the tank body 1. The sleeve 51 is fitted outside the sampling tube 31. A guide tube 312 is fixed to the sampling tube 31 at the position corresponding to the discharge port 311. A guide groove 52 adapted to the guide tube 312 is provided on the sleeve 51. An elastic element is provided at the end of the side wall of the guide groove 52 away from the tank body 1.

[0046] Specifically, in the above embodiment, two sets of linear drive mechanisms are used to drive the sampling tube 31 and the stop block 32 respectively, to adjust the position of the stop block 32 relative to the sampling tube 31 and the position of the sampling tube 31 relative to the tank body 1. The two sets of linear drive mechanisms need to be driven in a fixed sequence, and there are high requirements for the driving distance. For example, when driving the sampling tube 31 from the initial position to the sampling position, the stop block 32 needs to move at the same speed to ensure that the sampling tube 31 and the stop block 32 remain relatively stationary. In this embodiment, a drive assembly 4 is provided on the side wall of the tank body 1. The drive assembly 4 can drive the sampling tube 31 and the stop block 32 to move synchronously or relative to each other. Furthermore, the tank body 1 is also provided with a limiting member for restricting the position of the sampling tube 31, such as... Figure 4 As shown, the drive assembly 4 includes a drive unit and an adjustment unit. The adjustment unit includes an adjustment rod 41, which extends from the end of the sampling tube 31 outside the tank 1 into the interior of the sampling tube 31. In this embodiment, the adjustment rod 41 is dynamically sealed to the sampling tube 31, and the end of the adjustment rod 41 inside the sampling tube 31 is fixedly connected to the stop block 32. The portion of the adjustment rod 41 outside the sampling tube 31 is fitted with a first spring 411. The drive unit includes a cylinder 42 (which can also be an electric push rod or a hydraulic cylinder) fixedly connected to the outside of the tank 1. The cylinder 42 is arranged parallel to the sampling tube 31. A connecting block 412 is fixedly connected to the end of the adjustment rod 41 outside the sampling tube 31. The connecting block 412 is fixedly connected to the output end of the cylinder 42, so that when the cylinder 42 extends or retracts, it can drive the adjustment rod 41 to move axially along the sampling tube 31. When the stop block 32 is in the second position relative to the sampling tube 31, the connecting block 412 contacts the first spring 411. Figure 4 As shown.

[0047] Sampling tube 31 has an initial position and a sampling position relative to tank 1:

[0048] When the sampling tube 31 is in the initial position, one end of the sampling tube 31 corresponding to the inside of the tank 1 is flush with the inner wall of the tank 1, so as to prevent the tube body of the sampling tube 31 from interfering with the formation of the flow field inside the tank 1.

[0049] When sampling tube 31 is in the sampling position, such as Figure 3 As shown, the sampling tube 31 is at its maximum distance from the inner wall of the tank 1 at one end, to ensure that the sampled solution is fully stirred.

[0050] To ensure that the adjusting rod 41 can synchronously drive the sampling tube 31 and the stop 32, or independently drive the stop 32 relative to the sampling tube 31, a limiting component 5 is also provided on the tank body 1. The limiting component 5 is used to limit the sampling tube 31 to the initial position or the sampling position. Optionally, the limiting component 5 includes a sleeve 51 fixed to the tank body 1, such as... Figure 6As shown, the sleeve 51 is a pipe with openings at both ends. Preferably, the inner diameter of the sleeve 51 is equal to the outer diameter of the sampling tube 31. The sleeve 51 is fitted onto the outside of the sampling tube 31, that is, the sleeve 51 is also installed radially on the outer wall of the tank 1. A guide tube 312 is fixedly connected to the sampling tube 31 at the position corresponding to the outlet 311. The guide tube 312 is provided to prevent the solution from flowing from the outlet 311 to the outer wall of the sampling tube 31. The opening of the guide tube 312 is vertically downward, and a guide groove 52 is provided on the sleeve 51 to guide and limit the guide tube 312. The guide tube 312 extends from the guide groove 52 to the sleeve 51. Externally, since the guide tube 312 is fixed to the outer wall of the sampling tube 31, the distance that the guide tube 312 moves along the guide groove 52 is the distance that the sampling tube 31 can move. When the sampling tube 31 is in the initial position, the guide tube 312 is at the end of the guide groove 52 away from the outer wall of the tank 1, while when the sampling tube 31 is in the sampling position, the guide tube 312 is at the end of the guide groove 52 close to the outer wall of the tank 1. In addition, the side wall of the guide groove 52 is provided with an elastic element. Optionally, the elastic element is an elastic protrusion 53 fixed to the side wall of the guide groove 52, and the elastic protrusion 53 is provided at the end of the guide groove 52 away from the outer wall of the tank 1.

[0051] When no sample is taken, the sampling tube 31 is in the above-mentioned initial position, and the stop block 32 is in the above-mentioned second position. At this time, the guide tube 312 is at the end of the guide groove 52 away from the tank body 1, and the elastic protrusion 53 is between the tank body 1 and the guide tube 312, and the elastic protrusion 53 is in contact with the guide tube 312.

[0052] During sampling, cylinder 42 drives adjusting rod 41 to move towards the side of tank 1. Restricted by the first spring 411, adjusting rod 41 cannot move relative to sampling tube 31. At this time, as adjusting rod 41 pushes stop 32 into tank 1, it pushes sampling tube 31 and stop 32 to move synchronously via the first spring 411. During this process, guide tube 312 moves along guide groove 52 towards the end of guide groove 52 closest to tank 1. When sampling tube 31 reaches the aforementioned sampling position, because guide tube 312 has moved to one end of guide groove 52 and is restricted by guide groove 52, it cannot continue to move. Therefore, sampling tube 31 also cannot continue to move. At this time, the adjusting rod 41 is continuously driven towards sampling tube 31. As the cylinder moves, the adjusting rod 41 pushes the stop 32 to slide relative to the sampling tube 31. The connecting block 412 compresses the first spring 411 to store force, thereby adjusting the stop 32 relative to the sampling tube 31 to the first position mentioned above. The solution in the tank 1 enters the sampling tube 31 through the end of the sampling tube 31 inside the tank 1. After the sampling tube 31 is filled with solution, the cylinder 42 drives the adjusting rod 41 to move away from the tank 1 (hereinafter referred to as reverse movement). During this process, the first spring 411 restores and adjusts the relative position of the stop 32 and the sampling tube 31. The sampling tube 31 remains in the sampling position, and the stop 32 is adjusted from the first position to the second position. As the adjusting rod 41 moves, the solution in the tank 1 enters the sampling tube 31. Continuing the reverse movement, since the solenoid valve at the outlet 311 is closed, and the solution in the sampling tube 31 is incompressible or difficult to compress, the sampling tube 31 will move along with the stop block 32 when the adjusting rod 41 pulls the stop block 32. During this process, the stop block 32 remains in the second position relative to the sampling tube 31, and the guide tube 312 moves along the guide groove 52. After the elastic protrusion 53 is deformed by the compression, it reaches the end of the guide groove 52 away from the tank body 1. At this time, the sampling tube 31 returns to the initial position. Then, the solenoid valve is opened, and the stop block 32 is pulled by the adjusting rod 41 to continue sliding to the third position. At this time, because the guide tube 312 has moved to the other end of the guide groove 52... At one end, the sampling tube 31 is restricted from moving. The baffle 32 slides relative to the sampling tube 31 and pushes the solution in the sampling tube 31 toward the outlet 311. During this process, the internal space of the sampling tube 31 is divided into a first chamber and a second chamber by the baffle 32. The first chamber is connected to the tank 1, and the second chamber is connected to the outlet 311. As the baffle 32 moves from the second position to the third position, the volume of the first chamber gradually increases, while the volume of the second chamber gradually decreases. When the baffle 32 moves relative to the sampling tube 31 to the third position, the solution in the sampling tube 31 is completely pushed out. As the space of the first chamber gradually increases, the solution in the tank 1 will enter the first chamber.After sampling is completed, the solenoid valve remains open, driving the adjusting rod 41 to move forward. Because the guide tube 312 is restricted by the elastic protrusion 53, the friction between the stop block 32 and the sampling tube 31 is insufficient to move the sampling tube 31. The sampling tube 31 remains in its initial position, while the stop block 32 is pushed by the adjusting rod 41 from the third position back to the second position, gradually reducing the volume of the first chamber and pushing all the solution inside the first chamber back into the tank 1 to participate in mixing.

[0053] In this embodiment, by the synchronous or relative movement of the stop block 32 and the sampling tube 31, and in conjunction with the limiting member restricting the position of the sampling tube 31, the movement of the stop block 32 has the following effects: ensuring that the volume of the solution sampled each time is equal; enabling all or to the maximum extent that the solution in the sampling tube 31 can be discharged from the outlet 311, reducing the residual solution on the inner wall of the sampling tube 31; ensuring that when the sampled solution is released, the second chamber in the sampling tube 31 is always separated from the space inside the tank 1; and enabling the stop block 32 to adjust the sampling tube 31 back and forth between the initial position and the sampling position.

[0054] In another embodiment of the present invention, a sliding block 33 is provided inside the sampling tube 31, and an adjusting rod 41 passes through the middle of the sliding block 33. A second spring 34 is provided inside the sampling tube 31 to maintain the relative position of the sliding block 33 and the sampling tube 31. The sliding block 33 separates a compensation cavity 35 inside the sampling tube 31, and the compensation cavity 35 is connected to the outside of the sampling tube 31.

[0055] Specifically, in the above embodiment, after the sampling tube 31 is adjusted to the sampling position, the adjusting rod 41 needs to continue moving forward to push the stop 32 from the second position to the first position. This process requires both compressing the deformation of the first spring 411 and overcoming the pressure from the liquid inside the tank 1. Furthermore, since the solenoid valve needs to remain closed, this further makes it difficult to push the stop 32 (equivalent to the end of the syringe being blocked, making it difficult to pull or push the piston to move inside the cylinder). In this embodiment, a sliding block 33 is provided inside the sampling tube 31, such as... Figure 5As shown, the sliding block 33 is a cylinder, and the adjusting rod 41 passes through the sliding block 33 and is dynamically sealed to the sliding block 33. Its diameter is equal to the inner diameter of the sampling tube 31, and the sliding block 33 is dynamically sealed to the sampling tube 31. A second spring 34 is provided inside the sampling tube 31 to maintain the relative position of the sliding block 33 and the sampling tube 31. The sliding block 33 separates a compensation cavity 35 inside the sampling tube 31. Unlike the above embodiment, since the sliding block 33 needs to be moved to adjust the air pressure in the second cavity to ensure that the stop block 32 can be smoothly adjusted from the second position to the first position, the compensation cavity 35 needs to be connected to the outside. Since the sampling tube 31 is connected to the outside, in this embodiment, the diameter of the small hole through which the adjusting rod 41 passes is larger than the diameter of the adjusting rod 41, so as to ensure that the compensation cavity 35 is connected to the outside and to avoid friction between the adjusting rod 41 and the sampling tube 31. The second spring 34 is disposed in the compensation cavity 35. One end of the second spring 34 is fixedly connected to the sliding block 33, and the other end of the second spring 34 is fixedly connected to the inner wall of the sampling tube 31, so that the sliding block 33 can slide to adjust the volume of the second chamber, thereby ensuring that the stop block 32 is not difficult to push due to excessive resistance when it is adjusted from the second position to the first position.

[0056] Furthermore, the sliding block 33 has a blocking position and an open position during its sliding stroke within the sampling tube 31. The sampling tube 31 is also provided with a locking member 6, which is used to lock the sliding block 33 in the open position.

[0057] Optionally, the locking member 6 includes a locking pin 61 that is radially disposed through the sampling tube 31, and the sliding block 33 has an insertion hole 331 that cooperates with the locking pin 61. The end of the locking pin 61 that cooperates with the sliding block 33 is wedge-shaped, and a third spring 62 is provided on the outer wall of the sampling tube 31 to maintain the relative position of the locking pin 61 and the sampling tube 31.

[0058] Specifically, during the stroke of the sliding block 33 along the axial direction of the sampling tube 31, it has a blocking position and an open position. When the sliding block 33 is in the blocking position, such as... Figure 5 As shown, the sliding block 33 separates the second chamber from the outlet 311, preventing the solution in the second chamber from being discharged through the outlet 311. When the sliding block 33 is in the open position, the outlet 311 is fully connected to the second chamber, allowing the solution in the second chamber to be discharged through the outlet 311. This configuration simplifies the control procedure by replacing the solenoid valve with the sliding block 33. To ensure that the stop block 32 can move smoothly from the third position to the second position, i.e., during the entire process of the stop block 32 moving from the third position to the second position, the outlet 311 needs to be connected to the second chamber. Therefore, in this embodiment, the sampling tube 31 is also equipped with a locking member 6 for locking the sliding block 33 in the open position, such as... Figure 5As shown, the locking element 6 includes a locking pin 61 arranged radially along the sampling tube 31. Figure 5 The locking pin 61 is set parallel to the guide tube 312, and the sliding block 33 has an insertion hole 331 for engaging the locking pin 61. The end of the locking pin 61 inside the sampling tube 31 is wedge-shaped. When the sliding block 33 is in the blocked position, the wedge-shaped surface of the locking pin 61 faces the sliding block 33. This allows the sliding block 33 to push the locking pin 61 out of the sampling tube 31 when adjusting from the blocked position to the open position. The outer wall of the sampling tube 31 is provided with a third... Spring 62, the third spring 62 is fitted onto the portion of the locking pin 61 outside the sampling tube 31, and one end of the third spring 62 is fixedly connected to the outer wall of the sampling tube 31. A fixing block 63 is fixedly connected to the end of the locking pin 61 outside the sampling tube 31, and the other end of the third spring 62 is fixedly connected to the fixing block 63. When the third spring 62 is in its natural state, the length of the locking pin 61 extending into the sampling tube 31, i.e., the aforementioned compensation cavity 35, is at its maximum. Furthermore, in this embodiment, the diameter of the outlet 311 is smaller than the inner diameter of the sampling tube 31. Figure 6 As shown, the sleeve 51 is provided with a relief groove 54 for the locking pin 61 and the third spring 62 to pass through, so as to avoid the setting of the sleeve 51 affecting the synchronous movement of the locking pin 61 with the sampling tube 31.

[0059] When not sampling, the sliding block 33 remains in the blocking position, that is, the sliding block 33 is on the right side of the guide tube 312 in Figure 5. During sampling, as the sampling tube 31 is adjusted from the initial position to the sampling position, the stop block 32 is adjusted from the second position to the first position, the stop block 32 is adjusted from the first position to the second position, and the sampling tube 31 is adjusted from the sampling position to the initial position, the sliding block 33 remains in the above-mentioned blocking position under the elastic force of the second spring 34. When the sampling tube 31 returns to the initial position, as the stop block 32 moves from the second position to the third position under the pull of the adjusting rod 41, because the diameter of the outlet 311 is smaller than the inner diameter of the sampling tube 31, the stop block 32 will cause the above-mentioned second position to be blocked during the sliding process from the second position to the third position. The increased pressure in the chamber pushes the sliding block 33 to the open position. During this stage, the extension speed of the cylinder 42 can be appropriately increased to ensure that the stop block 32 can slide quickly a certain distance, allowing the pressure of the solution in the second chamber on the sliding block 33 to rise sufficiently to push the sliding block 33 through the locking pin 61 (pushing the locking pin 61 to retract) and reach the open position. The locking pin 61, squeezed by the sliding block 33, first moves outwards from the sampling tube 31. During this process, the third spring 62 is stretched. When the sliding block 33 moves to the open position, the locking pin 61 corresponds to the insertion hole 331. The locking pin 61 will then reset under the pull of the third spring 62 and insert into the insertion hole 331, thus locking the sliding block 33. Preferably, a push block is fixed to the outer wall of the adjusting rod 41, such as... Figure 7 As shown, when the stop block 32 is in the second position relative to the sampling tube 31, the push block is in contact with the sliding block 33. When the stop block 32 is driven to move from the second position to the third position, the push block will be driven by the adjusting rod 41 to push the sliding block 33 to move synchronously with the stop block 32 until the sliding block 33 moves to the open position and is locked. At this time, the stop block 32 just reaches the third position. After all the solution in the second chamber is released, the sliding block 33 is kept in the open position. The stop block 32 is pushed from the third position to the second position by the adjusting rod 41. After the stop block 32 returns to the second position, the locking pin 61 is manually pulled to move to the outside of the sampling tube 31 to release the lock on the sliding block 33. The sliding block 33 will then be adjusted from the open position to the blocked position under the action of the second spring 34.

[0060] Furthermore, a trigger rod 43 is installed on the adjusting rod 41. When the stop block 32 is driven from the third position to the second position, the trigger rod 43 releases the locking pin 61 from locking the sliding block 33.

[0061] Specifically, to further simplify the operation process and achieve passive locking of the sliding block 33 by the locking pin 61 when the stop block 32 moves from the third position to the second position, in this embodiment, a trigger rod 43 is installed on the adjusting rod 41, such as... Figure 7As shown, the trigger rod 43 is fixed to the connecting block 412 at the end of the adjusting rod 41, and the trigger rod 43 is set with the fixing block 63 on the locking pin 61. The end of the trigger rod 43 away from the connecting block 412 is wedge-shaped. When the adjusting rod 41 drives the stop block 32 to move from the third position to the second position, the trigger rod 43 moves synchronously with the adjusting rod 41 and moves to the position of the locking pin 61 on the sampling tube 31. When the stop block 32 moves to the second position, the wedge-shaped surface on the trigger rod 43 contacts the fixing block 63 and pushes the locking pin 61 to move to the outside of the sampling tube 31 through the fixing block 63. When the stop block 32 moves to the second position, the locking pin 61 releases the lock on the sliding block 33. The sliding block 33 automatically blocks the outlet 311 under the push of the second spring 34.

[0063] Specifically, such as Figures 1 to 3 As shown, the stirring assembly 2 includes a stirring shaft 21 disposed inside the tank 1. The stirring shaft 21 is coaxially disposed with the tank 1, and a plurality of stirring blades 22 are fixedly connected to the stirring shaft 21. The plurality of stirring blades 22 are fixed at different heights of the stirring shaft 21, and the stirring blades 22 at the same height of the stirring shaft 21 are arranged in a circumferential array with the central axis of the stirring shaft 21 as the center. A drive motor 23 is installed on the top of the tank 1. The drive motor 23 is a geared motor. The upper end of the stirring shaft 21 extends through to the outside of the tank 1 and is connected to the output shaft of the drive motor 23, so that the drive motor 23 can drive the stirring shaft 21 to rotate, thereby stirring the solution inside the tank 1.
