Description

Technical Field

[0001] This application relates to the field of chemical production equipment technology, and in particular to a creatine mother liquor treatment device. Background Technology

[0002] Creatine is an important amino acid derivative that is widely used in food, medicine, health products and other fields. Its production process usually generates a large amount of mother liquor containing uncrystallized creatine and other impurities. If this mother liquor is not treated in a timely and effective manner, it will not only waste resources, but also increase production costs and impose a certain burden on enterprises and the environment. Therefore, efficient treatment of creatine mother liquor has become an important technical requirement in this field.

[0003] In existing technologies, simple stirred tanks or storage tanks are typically used for temporary storage and basic treatment of creatine mother liquor. For example, a stirring component is installed inside the tank to stir the mother liquor. During the stirring process, an external heating device is used to assist in raising the temperature, thereby improving the solubility and crystallization effect of creatine in the mother liquor. However, the above-mentioned treatment equipment has a simple structure and usually cannot monitor or sample the crystal sedimentation status in the mother liquor in a timely manner during the stirring process. This results in inconvenient sampling and poor sample representativeness, which in turn affects the timeliness and accuracy of process control.

[0004] Therefore, the main shortcoming of the existing technology is that it cannot effectively achieve the simultaneous stirring and heating of the mother liquor and the convenient and representative sample collection of the settled mother liquor. This results in a lack of timely and accurate sampling methods in the creatine mother liquor processing process, which restricts the further improvement of overall production efficiency and product quality. Utility Model Content

A manual pull rod is provided in the middle of the sedimentation and diversion sample sampling chamber to open and close the liquid flow channel between the two spherical chambers. A sampling port is provided above the spherical chamber away from the tank in the sedimentation and diversion sample sampling chamber.

[0007] In one optional embodiment, the tank has a double-layer structure, comprising an outer container shell and an inner cavity. The outer container shell is cylindrical, and the inner cavity is located inside the outer container shell to contain the creatine mother liquor to be treated. The top of the inner cavity is provided with a cover assembly, which is connected to the outer container shell by a hinge. The cover assembly consists of two semi-circular covers, which are connected by a hinge and can achieve a semi-open state of the top opening of the inner cavity.

[0008] In one optional embodiment, the heater is an electric heater, which is disposed between the outer container shell and the inner cavity and closely attached to the bottom wall of the inner cavity. The heater is used to uniformly heat the mother liquor within a preset temperature range. An electrical control box is fixedly disposed on the side wall of the outer container shell, and the heater is connected to the electrical control box.

[0009] In one optional embodiment, the stirring assembly includes a stirring shaft and stirring blades. The stirring shaft passes vertically through the upper cover assembly and extends into the internal receiving cavity. The stirring blades are fixedly connected to the stirring shaft. A bracket is fixedly provided on the outer container shell, and a stirring motor and a reduction mechanism are fixedly installed on the bracket. The output end of the stirring motor is connected to the reduction mechanism, and the reduction mechanism is connected to the stirring shaft.

[0010] In one optional embodiment, an overflow recovery and exhaust assembly is provided above the side wall of the outer container shell. The overflow recovery and exhaust assembly includes an overflow port, an external container, a return pipeline, and an exhaust valve. The overflow port is located on the upper inner wall of the outer container shell and communicates with the internal receiving cavity. The external container communicates with the internal receiving cavity through the overflow port. The return pipeline is located at the bottom of the external container and passes through the lower part of the side wall of the outer container shell before connecting to the internal receiving cavity. The exhaust valve is located on the external container, and a return on / off valve is provided on the return pipeline.

[0011] In one optional embodiment, the two spherical chambers of the sedimentation diversion sample sampling chamber are a first spherical chamber and a second spherical chamber; the first spherical chamber is connected to the inside of the tank and is used to receive creatine mother liquor; the second spherical chamber is connected to the horizontal outer side of the first spherical chamber, and a sampling port is provided on the second spherical chamber; the manual lever is used to control the opening and closing of the liquid flow channel between the first spherical chamber and the second spherical chamber.

[0012] In one alternative embodiment, a sealing cap is provided at the sampling port.

[0013] In one optional embodiment, a drain assembly is provided at the bottom of the tank, the drain assembly including a drain pipe and a drain valve, the drain pipe being disposed at the bottom end of the tank, the drain valve being disposed on the drain pipe, and the bottom end face of the tank being a conical inclined guide surface.

[0014] Compared with the prior art, this application has the following beneficial effects:

[0015] 1. This application provides a creatine mother liquor treatment device, in which a heater is located inside the bottom of the tank. This arrangement allows the heat generated by the heater to directly act on the bottom area of ​​the tank. Under gravity, the mother liquor typically accumulates at the bottom of the tank. The heat generated by the bottom heater can be rapidly and evenly transferred upwards to the entire containment cavity, thereby reducing the localized overheating or uneven heating that is common with traditional side-wall heating methods. This structural approach improves the overall heating efficiency to a certain extent, enabling the mother liquor to reach a suitable temperature for sedimentation and crystallization more quickly, thus contributing to improved mother liquor treatment results.

[0016] 2. To achieve a more controlled sampling process, this application includes a sedimentation and diversion sampling chamber located on the lower side of the tank. A drain valve is installed at the drain outlet connected to the sedimentation and diversion sampling chamber. The sedimentation and diversion sampling chamber adopts a gourd-shaped structure with two spherical chambers arranged laterally. A manual lever is installed in the middle of the sedimentation and diversion sampling chamber to open and close the liquid flow channel between the two spherical chambers. This structural design isolates the sampling area outside the tank. Because the drain valve between the tank and the sedimentation and diversion sampling chamber is closed, the mother liquor has sufficient time to settle naturally in the spherical chamber near the tank, thus making the sampled liquid more stable. After the expected sedimentation state is achieved, the flow channel between the two spherical chambers is activated by manually pulling the lever, transferring a portion of the stabilized mother liquor to the spherical chamber away from the tank. This improves the representativeness of the collected sample and provides a more accurate sample basis for subsequent detection and process analysis.

[0017] 3. This application employs a manual lever to control the transfer of liquid between the two spherical chambers, allowing operators to initiate the sampling process at the appropriate time. After the mother liquor has settled and stabilized, the lever is opened, allowing the liquid to flow orderly into the spherical chambers away from the tank. This segmented control design reduces the risk of unsettled mother liquor mixing into the sampling area due to excessive flow velocity, thereby helping to improve sampling quality and reduce uncertainties in the operation process, providing a reliable basis for production process and quality inspection.

[0024] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions in the embodiments of this application are described clearly and completely below. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are also within the scope of protection of this application.

[0025] like Figures 1-3 As shown, this application provides a creatine mother liquor treatment device, including a tank 1, as described above. Figure 2As shown, a heater 2 is installed inside the bottom of the tank 1, a stirring assembly 3 is installed inside the tank 1, and a sedimentation diversion sample sampling chamber 4 is installed in the lower middle of the side of the tank 1. One end of the sedimentation diversion sample sampling chamber 4 is connected to the inside of the tank 1. A drain valve is installed at the drain pipe port of the tank 1 connected to the sedimentation diversion sample sampling chamber 4. The sedimentation diversion sample sampling chamber 4 is a gourd-shaped structure with two spherical chambers arranged horizontally. A manual pull rod 5 is installed in the middle of the sedimentation diversion sample sampling chamber 4 to open and close the liquid flow channel between the two spherical chambers. A sampling port 401 is installed above the spherical chamber of the sedimentation diversion sample sampling chamber 4 away from the tank 1.

[0026] In this embodiment, the heater 2 is located inside the bottom of the tank 1. This arrangement allows the heat generated by the heater 2 to directly act on the bottom area of ​​the tank 1. Under gravity, the mother liquor typically accumulates at the bottom of the tank 1. The heat generated by the heater 2 at the bottom can be rapidly and evenly transferred upwards to the entire containment cavity 12, thereby reducing the localized overheating or uneven heating that is common with traditional sidewall heating methods. This structural approach improves the overall heating efficiency to a certain extent, enabling the mother liquor to reach a suitable temperature for sedimentation and crystallization more quickly, thus contributing to improved mother liquor treatment.

[0027] In this embodiment, to achieve a more controlled sampling process, a drain valve is designed and installed at the drain port of the tank 1 connected to the sedimentation and diversion sample sampling chamber 4. When the drain valve is open, the mother liquor enters the spherical chamber near the tank 1 by natural flow, but its flow rate is difficult to adjust directly, that is, the rate at which the liquid enters the first spherical chamber is difficult to control precisely. At this time, the drain valve between the tank 1 and the sedimentation and diversion sample sampling chamber 4 is closed, and the liquid flow channel between the two spherical chambers is opened by operating the manual lever 5. The mother liquor that has settled and stabilized in the spherical chamber near the tank 1 can then enter the spherical chamber away from the tank 1 in a controlled manner.

[0028] This structural design isolates the sampling area outside of tank 1. Due to the closed drain valve between tank 1 and the sedimentation diversion sampling chamber 4, the mother liquor has sufficient time to settle naturally in the spherical chamber near tank 1, resulting in a more stable liquid state. Once the sedimentation reaches the desired state, the flow channel between the two spherical chambers is activated by manually pulling lever 5, transferring a portion of the stabilized mother liquor to the spherical chamber away from tank 1. This improves the representativeness of the collected samples and provides a more accurate sample basis for subsequent testing and process analysis.

[0029] Furthermore, a manual lever 5 controls the flow of liquid between the two spherical chambers, allowing operators to initiate the sampling process at the appropriate time. After the mother liquor has settled and stabilized, opening the manual lever 5 directs the liquid in an orderly manner towards the spherical chamber furthest from tank 1. This segmented control design reduces the risk of unsettled mother liquor contaminating the sampling area due to excessive flow velocity, thereby improving sampling quality and reducing uncertainties during operation, providing a reliable basis for production processes and quality control.

[0030] Meanwhile, in this embodiment, the sampling port 401 above the second spherical chamber 42 is positioned reasonably, located on the side away from the tank 1. This allows operators to conveniently perform sampling without needing to penetrate deep into the tank 1. This approach not only reduces interference with the mother liquor treatment process but also mitigates potential risks during sampling, significantly improving the overall ease of operation of the device.

[0031] In some embodiments, the tank 1 has an inner and outer double-layer structure, such as... Figure 2 As shown, the tank 1 includes an outer container shell 11 and an inner receiving cavity 12. The outer container shell 11 has a cylindrical structure. The inner receiving cavity 12 is disposed inside the outer container shell 11 and is used to contain the creatine mother liquor to be treated. The top of the inner receiving cavity 12 is provided with a top cover assembly 121. The top cover assembly 121 is connected to the outer container shell 11 by a hinge. The top cover assembly 121 consists of two semi-circular top covers. The two semi-circular top covers are connected by a hinge and can realize a semi-open state of the top opening of the inner receiving cavity 12.

[0032] In this embodiment, the tank 1 adopts a double-layer structure, with an outer cylindrical outer container shell 11 and an independent inner cavity 12. In this structure, the heater 2 is positioned between the bottom of the inner cavity 12 and the outer container shell 11, closely adhering to the bottom wall of the inner cavity 12. This arrangement allows the heat generated by the heater to be transferred more directly and effectively to the creatine mother liquor within the inner cavity 12. Simultaneously, the outer container shell 11 helps reduce heat loss. Compared to a traditional single-layer structure, this double-layer design better saves energy and helps maintain temperature stability during the creatine mother liquor treatment process.

[0033] Specifically, the internal containment cavity 12 is located within the cylindrical outer container shell 11, forming a thermally insulated space of a certain thickness between them. This thermal insulation structure can reduce heat loss to a certain extent, avoiding safety hazards caused by excessively high temperatures on the outer surface of the equipment. At the same time, this thermally insulated space also makes it easier to stabilize and control the temperature within the internal containment cavity 12, with smaller temperature fluctuations. This helps to process the creatine mother liquor under more stable temperature conditions, thereby reducing the potential for process instability and decreased treatment efficiency caused by temperature fluctuations, and improving the safety of equipment operation.

[0034] Furthermore, the top cover assembly 121 of the internal receiving cavity 12 consists of two semi-circular covers connected by hinges, allowing for a partially open top opening. Compared to traditional integral cover structures, this design allows for partial opening of the top of the internal receiving cavity 12 according to actual needs, facilitating internal inspection, cleaning, and maintenance, and reducing waste caused by rapid heat loss and mother liquor evaporation. In addition, this partial opening method reduces the operational difficulty during equipment inspection and maintenance, minimizes inconvenience to personnel and potential safety risks, and significantly improves the practicality and maintenance efficiency of the equipment. Optionally, such as... Figure 1 As shown, the upper cover assembly 121 is provided with an inlet pipe 122 to facilitate the delivery of the mother liquor to be processed into the internal receiving cavity 12.

[0035] In some embodiments, such as Figure 2 As shown, heater 2 is an electric heater. Heater 2 is disposed between the outer container shell 11 and the inner receiving cavity 12 and is in close contact with the bottom wall of the inner receiving cavity 12. Heater 2 is used to uniformly heat the mother liquor within a preset temperature range. An electrical control box 111 is fixedly disposed on the side wall of the outer container shell 11, and heater 2 is connected to electrical control box 111.

[0036] In this embodiment, heater 2 is an electric heater, arranged on the bottom wall of the internal receiving cavity 12, which enables heat to be directly and effectively conducted to the mother liquor in the bottom area of ​​the receiving cavity 12. Since the mother liquor itself has certain density differences and particle settling characteristics, the denser mother liquor is usually located at the bottom of the internal receiving cavity 12. Therefore, the heater set at the bottom can enable heat to be gradually and naturally transferred upwards evenly from the bottom. This structural layout reduces the possibility of local overheating or sediment formation, thereby helping to improve the overall quality and efficiency of mother liquor treatment.

[0037] Furthermore, the heater 2 is located between the outer container shell 11 and the inner cavity 12. This arrangement allows heat to be better transferred into the inner cavity 12 and reduces heat loss to some extent. The outer container shell 11 provides good insulation for heat transfer between the inside and outside, improving thermal efficiency and reducing the temperature of the outer surface of the device. This structural layout improves energy efficiency while helping to reduce safety risks during equipment operation, decreasing the possibility of accidental burns to operators, and making the equipment safer and more reliable to operate.

[0038] Furthermore, the electrical control box 111 is fixed to the side wall of the outer container shell 11 and connected to the heater 2. This layout allows operators to easily adjust the temperature or control the start / stop of the heater without having to approach the bottom or interior of the equipment, reducing the difficulty of operating the equipment. Because the electrical control box 111 is located on the outer container shell 11, operators can more intuitively observe and adjust the operating status of the equipment, effectively improving the ease of operation and reducing the complexity of maintenance and the risks involved in the operation.

[0039] In some embodiments, such as Figure 3 As shown, the stirring assembly 3 includes a stirring shaft 31 and a stirring blade 32. The stirring shaft 31 passes vertically through the upper cover assembly 121 and extends into the internal receiving cavity 12. The stirring blade 32 is fixedly connected to the stirring shaft 31, as shown. Figure 3 As shown, a bracket 112 is fixedly installed on the outer container shell 11, and a stirring motor 7 and a reduction mechanism 8 are fixedly installed on the bracket 112. The output end of the stirring motor 7 is connected to the reduction mechanism 8, and the reduction mechanism 8 is connected to the stirring shaft 31.

[0040] In this embodiment, the stirring shaft 31 passes vertically through the top cover assembly 121 and extends into the internal receiving cavity 12. This vertical arrangement allows the stirring shaft 31 to be located in the central region of the internal receiving cavity 12, thereby ensuring that the stirring blades 32 are more evenly distributed at different heights. When the stirring shaft 31 rotates, the mother liquor at each height can be thoroughly stirred, reducing the possibility of local crystallization or particle deposition in the mother liquor and helping to improve the overall uniformity of the mother liquor. At the same time, since the stirring blades 32 are firmly connected to the stirring shaft 31, this stable connection reduces the possibility of the blades shaking or shifting position during high-speed stirring, thus making the stirring operation more stable and reliable.

[0041] Furthermore, the stirring motor 7 and the reduction gear 8 are located on the outside of the outer container shell 11 and are securely fixed by the bracket 112. This external arrangement separates the transmission device from the mother liquor inside the tank, helping to reduce the risk of corrosion or contamination caused by direct contact between the transmission components and the mother liquor. During routine maintenance or upkeep, operators can directly inspect and maintain the motor and reduction gear without frequently opening the tank, making the operation process simpler and safer.

[0042] Meanwhile, the mixing motor 7 and the reduction gear 8 are located away from the humid and high-temperature environment inside the tank. This layout helps reduce the risk of wear or failure of the motor and reduction gear under harsh operating conditions, thus improving the reliability of the equipment. After long-term operation, the frequency of equipment maintenance and repair costs can also be reduced, thereby helping to extend the overall service life of the equipment and reduce the overall operating and maintenance costs.

[0043] In some embodiments, an overflow recovery and exhaust assembly 6 is provided above the side wall of the outer container shell 11, such as... Figure 3 As shown, the overflow recovery and exhaust assembly 6 includes an overflow port 61, an external container 62, a return pipe 63, and an exhaust valve 64. The overflow port 61 is located on the upper inner wall of the outer container shell 11 and is connected to the internal receiving cavity 12. The external container 62 is connected to the internal receiving cavity 12 through the overflow port 61. The return pipe 63 is located at the bottom of the external container 71 and passes through the lower part of the side wall of the outer container shell 11 before connecting to the internal receiving cavity 12. The exhaust valve 64 is located on the external container 62, and a return on / off valve 631 is provided on the return pipe 63.

[0044] Specifically, in this embodiment, an overflow port 61 is provided on the upper inner wall of the outer container shell 11, and the overflow port 61 is directly connected to the internal receiving cavity 12. When the height of the mother liquor or foam in the receiving cavity 12 rises due to stirring or temperature changes, the mother liquor or foam can automatically enter the external container 62 for temporary storage through the overflow port 61. This layout design effectively reduces the waste of raw materials and the risk of external equipment pollution caused by the direct overflow of mother liquor or foam, and helps to improve the resource utilization efficiency in the production process and improve environmental cleanliness.

[0045] In addition, the return pipe 63 is located at the bottom of the outer container 62, passes through the lower side wall of the outer container shell 11, and connects to the inner receiving cavity 12. Since this pipe is connected to the bottom of the outer container, the mother liquor that has undergone sedimentation treatment can be preferentially guided back to the bottom area of ​​the receiving cavity, reducing sedimentation and blockage during the mother liquor return process, and thus improving the recycling efficiency of the mother liquor and the stability of equipment operation.

[0046] Meanwhile, the top of the external container 62 is equipped with an exhaust valve 64. When the pressure inside the container is abnormal or excessive gas and foam are generated, the exhaust valve 64 can release excess gas in a timely manner, effectively reducing the risk of potential equipment damage. A return flow on / off valve 631 is also installed on the return pipeline 63, allowing operators to flexibly adjust the timing and flow rate of the return mother liquor entering the internal containment chamber 12 according to actual production needs. This valve combination design further enhances the controllability of equipment operation, improves the flexibility of process operation, and also helps to improve the overall safety and stability of the processing.

[0047] In some embodiments, the two spherical chambers of the sedimentation diversion sample sampling chamber 4 are a first spherical chamber 41 and a second spherical chamber 42, respectively. The first spherical chamber 41 is connected to the inside of the tank 1 and is used to receive creatine mother liquor. The second spherical chamber 42 is connected to the horizontal outer side of the first spherical chamber 41 and is provided with a sampling port 401. The manual lever 5 is used to control the opening and closing of the liquid flow channel between the first spherical chamber 41 and the second spherical chamber 42.

[0048] Specifically, in this embodiment, the first spherical chamber 41 of the sedimentation diversion sample sampling chamber 4 is directly connected to the interior of the tank 1. After stirring and heating, the mother liquor can naturally flow into the first spherical chamber 41 after opening the drain valve between the sedimentation diversion sample sampling chamber 4 and the tank 1. Once the drain valve is closed, the mother liquor entering the first spherical chamber 41 is separated from the mother liquor in the tank 1, and the liquid gradually stabilizes, promoting more thorough sedimentation of solid particles. This design layout is beneficial for improving sedimentation effects and creates favorable conditions for subsequent accurate sampling.

[0049] The second spherical chamber 42 is horizontally arranged outside the first spherical chamber 41. After the mother liquor in the first spherical chamber 41 has settled and stabilized, the liquid flows horizontally into the second spherical chamber 42 in a controlled manner after the opening degree of the manual lever 5 is controlled. This lateral connection method further slows down the liquid flow rate, making the mother liquor entering the second spherical chamber 42 more stable, reducing the possibility of insufficiently settled mother liquor entering the sampling area, and effectively improving the accuracy and representativeness of the sampling results.

[0050] A manual lever 5 is installed between the two spherical chambers, allowing the operator to select the appropriate liquid flow timing based on the actual settling of the mother liquor. This manual control method effectively prevents unstable settling mother liquor from entering the sampling chamber, reducing the uncertainty of sample quality and improving the accuracy of sample collection. Simultaneously, this structural arrangement enhances the flexibility and controllability of the sampling operation, better meeting the stringent sample quality requirements of actual production.

[0051] In some embodiments, a sealing cap 402 is provided at the sampling port 401.

[0052] In this embodiment, a sealing cap 402 is provided at the sampling port 401. The sampling port 401 is usually located on the outside of the device. When the sealing cap is not provided, external dust, impurities, or bacteria in the air can easily enter the sampling port 401, which may contaminate the sampled mother liquid. By adding a sealing cap 402 to the sampling port 401, the external environment can be better isolated, reducing the risk of dust, impurities, or bacteria entering the sampling area, thereby helping to improve the purity and accuracy of the sampled liquid.

[0053] The sealing cap 402 is directly installed above the sampling port 401. When taking samples, the operator only needs to open the sealing cap to quickly take samples, and then close it again to restore the sealed state. This convenient layout reduces the difficulty of sampling operations, reduces the complexity of operating steps and the possibility of human error, and further improves the convenience and practicality of equipment operation.

[0054] In some embodiments, a drain assembly 9 is provided at the bottom of the tank body 1. The drain assembly 9 includes a drain pipe 91 and a drain valve 92. The drain pipe 91 is located at the bottom end of the tank body 1, and the drain valve 92 is located on the drain pipe 91. The bottom end surface of the tank body 1 is a tapered inclined guide surface.

[0055] In this embodiment, the bottom of tank 1 is specifically designed as a conical inclined guide surface. After processing, the mother liquor will naturally converge along the inclined surface to drain pipe 91 under the action of gravity. Compared with the traditional flat-bottom structure, the conical bottom can better improve the thoroughness of drainage, reduce liquid residue and crystal deposition, thereby helping to achieve efficient discharge of mother liquor, reduce equipment cleaning frequency, and improve overall process efficiency.

[0056] Specifically, the drain pipe 91 is located at the bottom of the tank 1, allowing the liquid to flow smoothly from the lowest position without the need for additional power or manual assistance. The location of the pipe enables the mother liquor to be discharged automatically and quickly, significantly improving the drainage speed, shortening the processing cycle, and effectively reducing the efficiency reduction and cleaning difficulties caused by incomplete drainage, making the equipment operation process more efficient and convenient.

[0057] Furthermore, the drain valve 92 is directly mounted on the drain pipe 91, forming a simple and reliable control mechanism. During draining, operators only need to open and close the drain valve 92 to precisely control the liquid discharge volume, avoiding the cumbersome operations required by traditional draining methods that necessitate additional piping or equipment connections. This direct connection design not only significantly simplifies the operation process but also reduces potential risks during draining, improving equipment safety and the operator's experience.

[0058] In this embodiment, the operator first opens the tank 1 through the top cover assembly, then injects the creatine mother liquor to be treated into the internal cavity through the top opening. Afterwards, the top cover assembly is closed, or the creatine mother liquor can be injected directly into the internal cavity through the inlet pipe 122 on the top cover assembly without opening it. Next, the electrical control box 111 is activated, turning on the heater 2 to rapidly heat the mother liquor within a short time. Simultaneously, the stirring motor starts, driving the stirring shaft and blades in the stirring assembly 3 to rotate via the reduction mechanism, thoroughly stirring the mother liquor and ensuring a more uniform temperature distribution within the tank 1, thus facilitating the subsequent sedimentation and separation processes.

[0059] After heating and stirring, the mother liquor in tank 1 needs to settle for a period of time. Then, the drain valve between tank 1 and the sedimentation diversion sample sampling chamber 4 is opened. At this time, the manual lever 5 is in a state that can close the liquid flow channel between the two spherical chambers. In this way, the mother liquor in tank 1 flows naturally into the first spherical chamber 41 of the sedimentation diversion sample sampling chamber 4 through the connecting port at the bottom of the side under the influence of gravity. Then, the drain valve between tank 1 and the sedimentation diversion sample sampling chamber 4 is closed, so that the liquid in the first spherical chamber 41 tends to be stable. This makes the liquid in the first spherical chamber 41 unaffected by the mother liquor in tank 1, so that the solid particles can settle better and achieve liquid-solid separation. After the sedimentation reaches a certain level, the operator controls the liquid flow channel between the two spherical chambers by manually pulling lever 5, and slowly introduces the clarified mother liquor horizontally into the second spherical chamber 42, creating a more stable environment for the sampling operation.

[0060] Once the liquid state within the second spherical chamber 42 has stabilized, the operator opens the sealing cap on the sampling port 401 and collects a representative liquid sample from the sampling port 401 for testing and analysis to monitor the sedimentation treatment effect. After sampling, the sealing cap is immediately closed. If, during the treatment process, the mother liquor overflows into the overflow recovery and venting assembly due to stirring or temperature fluctuations, the operator can adjust the reflux valve to return the overflowed mother liquor to the tank. After the entire treatment is completed, the drain valve is opened, and the mother liquor is completely discharged through the drain pipe along the conical inclined guide surface at the bottom of the tank 1 for reuse after cleaning and maintenance.

[0061] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
