Description

Technical Field

[0001] The present invention belongs to the technical field of ore pulp processing, relates to a technology for improving the efficiency of ore pulp mother liquor separation, and particularly relates to ore pulp mother liquor separation equipment. Background Art

[0002] Mother liquor is a common byproduct of mineral processing. It typically refers to a liquid mixture containing mineral particles, impurities, and other chemical components produced during processes such as ore flotation, gravity separation, and chemical precipitation. Mother liquor generally falls into two categories: acidic and alkaline. Their chemical properties and mineral composition depend on factors such as ore type, processing methods, and additives.

[0003] The primary purpose of slurry separation is to achieve solid-liquid separation, remove suspended mineral particles and impurities, and meet environmental emission standards or further treatment requirements. An effective separation process can settle mineral particles in the slurry, resulting in a purer supernatant, thereby reducing the burden of subsequent processing and improving recycling rates. Technologies for achieving efficient separation have become key technologies in the mining industry.

[0004] In the prior art, physical or chemical methods are often used to improve the separation efficiency of the ore pulp mother liquor. For example, during the static separation process, particles sink to the bottom of the container through gravity sedimentation, forming a supernatant. However, for fine particles and dissolved impurities with low molecular weight, relying solely on gravity sedimentation is relatively limited, resulting in low separation efficiency and requiring a long separation time. Therefore, an increasing number of separation devices are incorporating ultrasonic components, which promote particle agglomeration, fragmentation, and accelerated sedimentation through the cavitation effect of ultrasound, achieving enhanced separation. The addition of ultrasound significantly shortens separation time and improves the removal rate of suspended particles in the ore pulp mother liquor.

[0005] However, while the use of ultrasonic components improves separation efficiency, it also introduces some challenges. First, when ultrasound waves act on the slurry mother liquor, they produce significant fluctuations in the liquid surface, creating strong disturbances within the liquid and leading to an unstable separation interface within the mother liquor. These surface fluctuations not only affect the smoothness of the separation process but also lead to unclear separation between the liquid surface and the solid-liquid interface, preventing the formation of a stable supernatant and lower sediment layer, thereby reducing separation effectiveness. Furthermore, excessive surface fluctuations can cause settled particles to resuspend, further impacting separation efficiency. Summary of the Invention

[0062] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0063] See also Figures 1 to 6 As shown, the specific embodiments provided by the present invention are as follows:

[0064] like Figures 1 to 4 As shown, the first embodiment of the present invention provides a slurry mother liquid separation device, comprising:

[0065] The device body 1 is formed with a cavity;

[0066] A flow stabilizing component 2 is slidably disposed in the cavity;

[0067] The flow stabilizing component 2 separates the cavity into a first cavity 301 and a second cavity 302 which are independent of each other;

[0068] The first cavity 301 is connected to the liquid inlet assembly 4 and is configured to provide a mother liquid static area;

[0069] The flow stabilizing component 2 is controlled by the liquid level of the mother liquid in the first cavity 301 and floats along the axis of the equipment body 1 to adjust the volume of the second cavity 302;

[0070] The second cavity 302 is provided with a gas pressure control component 5, and the gas pressure control component 5 is configured to release the gas in the second cavity 302, and the gas release flow rate Q is negatively correlated with the pressure P in the second cavity 302;

[0071] The ultrasonic component 6 is disposed at the bottom of the device body 1 and faces the first cavity 301 .

[0072] In this embodiment, the slurry-mother-liquid separation equipment utilizes a flow stabilization assembly 2 to effectively control liquid level fluctuations. Specifically, the cavity formed by the equipment body 1 is separated into a first cavity 301 and a second cavity 302 by the sliding flow stabilization assembly 2. The first cavity 301 is connected to the liquid inlet assembly 4, providing a resting area for the mother liquor. This ensures sufficient rest, reduces disturbance of suspended particles, and facilitates particle settling.

[0073] The design of the flow stabilizing component 2 enables it to float along the axis of the equipment body 1 according to the liquid level of the mother liquid in the first cavity 301, balancing the pressure changes within the system by changing the volume of the second cavity 302. When the liquid level in the first cavity 301 rises, the flow stabilizing component 2 floats up accordingly, compressing the volume of the second cavity 302; conversely, when the liquid level drops, the flow stabilizing component 2 floats down, thereby increasing the volume of the second cavity 302. This floating adjustment function ensures the smooth regulation of the internal pressure of the cavity throughout the separation process and avoids drastic fluctuations in the liquid level. Specifically, the slurry mother liquid separation equipment further ensures the stability of the liquid level during the separation process through the contact between the flow stabilizing component 2 and the mother liquid level, reducing the destabilizing effect of the ultrasonic component 6 on the mother liquid. Specifically, the flow stabilizing component 2 forms a stable isolation layer through direct contact with the mother liquid level, so that the liquid level fluctuations can be effectively suppressed under ultrasonic vibration, thereby maintaining the static state of the mother liquid. This design ensures the clarity of the separation liquid surface, makes the interface between the upper clear liquid and the lower sediment more stable, is conducive to the effective sedimentation of particles, and improves the separation efficiency of the mother liquor

[0074] In addition, the second cavity 302 is equipped with an air pressure control assembly 5, which is used to automatically adjust gas release when the internal pressure of the system changes. The gas release rate Q in the air pressure control assembly 5 is negatively correlated with the internal pressure P of the second cavity 302. That is, the higher the pressure, the less gas is released. Maintaining high pressure stability within the cavity helps enhance the suppressive effect of the flow stabilization assembly 2 on the liquid level, thereby reducing the amplitude of liquid level fluctuations under the action of ultrasound. Specifically, the air pressure control assembly 5 makes the gas release rate Q negatively correlated with the internal pressure P of the second cavity 302 to better cooperate with the stabilization effect of the flow stabilization assembly 2 on the liquid level. The gas release rate is designed to be negatively correlated with the cavity pressure because as the mother liquid level in the first cavity 301 gradually rises, the volume and weight of the mother liquid increase, and the impact on the fluctuation of the ultrasonic assembly 6 also increases. This liquid level fluctuation becomes more intense under the action of ultrasound. If not effectively controlled, the liquid level stability will be seriously affected.

[0075] To this end, the floating flow stabilization component 2 dynamically compresses the volume of the second chamber 302, causing the internal pressure of the second chamber 302 to increase simultaneously. In this case, if the gas is released too quickly, the pressure in the second chamber 302 will drop rapidly, and the flow stabilization component 2 will not be able to provide stable support pressure. Therefore, the gas release flow rate Q is designed to be negatively correlated with the internal pressure P, so that under high liquid level and high pressure conditions, the gas is released at a slower rate. This design ensures that the gas in the chamber is released slowly under high pressure, thereby maintaining a moderate gas pressure in the second chamber 302.

[0076] This air pressure regulation not only provides stable support for the flow stabilization component 2, but also further enhances its ability to suppress the liquid level when the liquid level is high and fluctuates significantly, allowing the liquid level to remain stable under the influence of ultrasound. Thus, at high liquid levels, the flow stabilization component 2 can more effectively suppress liquid level fluctuations, thereby ensuring a stable and efficient mother liquor separation process, resolving the problem of poor separation results caused by ultrasonic-induced liquid level fluctuations in the prior art.

[0077] The ultrasonic component 6 is mounted at the bottom of the device body 1, facing the first cavity 301. This component utilizes the cavitation and vibration effects of ultrasound to promote particle agglomeration and sedimentation in the slurry mother liquor, thereby accelerating the separation process. In this embodiment, the ultrasonic component 6 and the flow stabilization component 2 work together. The ultrasound accelerates the solid-liquid separation in the mother liquor, while the floating adjustment and air pressure control of the flow stabilization component 2 effectively suppress liquid level fluctuations, making the separation liquid surface more stable and clear, thereby improving the overall separation effect.

[0078] The second embodiment of the present invention provides a slurry mother liquid separation device, and based on the first embodiment, the flow stabilizing component 2 includes:

[0079] A sliding member 201 is provided on the inner wall surface of the cavity;

[0080] a flow stabilizing plate 202 connected to the sliding member 201 and capable of floating along the axis of the device body 1;

[0081] The flow stabilizing plate 202 is controlled to float when the liquid level of the mother liquid in the first cavity 301 increases, thereby reducing the volume of the second cavity 302 , and is controlled to fall when the liquid level of the mother liquid in the first cavity 301 decreases, thereby increasing the volume of the second cavity 302 .

[0082] In this embodiment, the flow stabilizing component 2 is further refined in design to more effectively control the liquid level stability and accurately adjust the volume of the second cavity 302. Specifically, the flow stabilizing component 2 is composed of a sliding member 201 provided on the inner wall of the cavity and a flow stabilizing plate 202 connected to the sliding member 201. The sliding member 201 enables the flow stabilizing plate 202 to float along the axis of the device body 1, thereby moving up and down in response to changes in the liquid level of the mother liquid in the first cavity 301. This design enables the flow stabilizing plate 202 to flexibly adjust its position according to the liquid level of the mother liquid, so as to more accurately control the pressure and gas release amount in the second cavity 302, thereby improving the stability and effect of the separation process.

[0083] When the liquid level of the mother liquid in the first chamber 301 rises, the flow stabilizing plate 202 rises accordingly, thereby gradually reducing the volume of the second chamber 302 and compressing the gas in the chamber. This design ensures that the air pressure provides sufficient support for the flow stabilizing plate 202, effectively reducing the impact of fluctuations on the mother liquid. As the pressure in the second chamber 302 increases, the air pressure control component 5 adjusts the amount of gas released, allowing the gas to be slowly discharged, maintaining a high pressure state to provide stable support for the flow stabilizing plate 202, and ensuring that the flow stabilizing plate 202 can provide greater stability when the mother liquid level is high and fluctuates greatly.

[0084] Conversely, when the mother liquor level in the first chamber 301 decreases, the flow stabilizer 202 sinks accordingly, increasing the volume of the second chamber 302. This adjustment action reduces the chamber pressure, appropriately reducing the support force on the flow stabilizer 202, thereby relieving some of the pressure in low liquid level conditions. This up-and-down adjustment mechanism enables the flow stabilizer assembly 2 to respond to changes in the mother liquor level at any time, ensuring that the gas in the second chamber 302 is always within a reasonable pressure range and preventing excessive liquid level fluctuations from interfering with the separation effect.

[0085] The design of the flow stabilization assembly 2 in this embodiment effectively controls mother liquor level fluctuations within a reasonable range, making the separation process smoother and more efficient. The floating response of the flow stabilization plate 202 ensures a dynamic balance between gas release and chamber pressure, achieving excellent pressure adaptation, particularly when the liquid level rises or falls. This significantly improves the separation of the ore pulp and mother liquor, overcoming the problem of poor separation results caused by liquid level fluctuations in traditional designs.

[0086] In one embodiment, the sliding member 201 is in the form of a sliding block and a sliding slot.

[0087] like Figures 5 and 6 As shown, the third embodiment of the present invention provides a pulp-mother-liquid separation device, and based on the previous embodiment, the flow stabilizing plate 202 includes:

[0088] A first plate 2021 and a second plate 2022;

[0089] The first plate 2021 and the second plate 2022 are configured to contact the liquid surface of the mother liquid in the first cavity 301;

[0090] Furthermore, the first plate 2021 is an annular structure, and the second plate 2022 is connected to the inner ring of the annular structure;

[0091] The first plate 2021 is made of a hard material, and the second plate 2022 is made of an elastic material.

[0092] In this embodiment, the structure of the flow stabilizer 202 is further optimized, with a combined design of a first plate 2021 and a second plate 2022 to better adapt to fluctuations in the mother liquor level and improve separation stability and efficiency. Specifically, the flow stabilizer 202 comprises a first plate 2021 and a second plate 2022. These two plates directly contact the mother liquor level within the first chamber 301, thereby stabilizing the liquid level and reducing fluctuations caused by ultrasonic waves.

[0093] The first plate 2021 is annular and made of a hard material to enhance its rigidity and stability. As the primary structure of the flow stabilizer 202, the first plate 2021 effectively resists pressure fluctuations and liquid level fluctuations in the mother liquid, ensuring overall structural strength. This annular design helps evenly distribute the liquid around the flow stabilizer 202, thereby minimizing the impact of liquid level fluctuations on the flow stabilizer assembly 2 and maintaining a more stable liquid surface.

[0094] The second plate 2022 is connected to the inner ring of the first plate 2021 and is made of an elastic material, allowing it to deform appropriately when the mother liquid fluctuates. The elastic design of the second plate 2022 allows it to fine-tune with small fluctuations in the mother liquid level, thereby absorbing some of the fluctuation energy and further reducing the impact of the liquid surface on the flow stabilizer 202. Through this elastic energy absorption, the second plate 2022 not only efficiently absorbs fluctuation energy but also mitigates the impact of ultrasonic vibrations on the mother liquid level.

[0095] This dual-layered flow stabilizer 202 design not only provides stable support through the rigid first plate 2021, but also dynamically adjusts to fluctuations with the help of the elastic second plate 2022, making the mother liquor level more stable during the separation process and thus improving the separation effect. When the mother liquor level experiences significant fluctuations, the combination of the first plate 2021 and the second plate 2022 disperses and absorbs the fluctuation energy, significantly reducing the impact on liquid level stability and maintaining a clear and stable interface between the upper clear liquid and the lower sediment layer.

[0096] The fourth embodiment of the present invention provides a slurry-mother-liquid separation device, and based on the previous embodiment, includes an energy absorbing structure (not shown in the figure);

[0097] The energy absorbing structure is provided on the wall surface of the flow stabilizing plate 202 facing the ultrasonic component 6;

[0098] Furthermore, the energy absorbing structure is configured to absorb and buffer the wave energy generated by the ultrasonic component 6;

[0099] The energy absorbing structure is a plurality of micro holes or micro grooves provided along the surface of the flow stabilizing plate 202 .

[0100] In this embodiment, the slurry-mother-liquid separation equipment further incorporates an energy-absorbing structure on the flow stabilizer 202 to more efficiently buffer the energy fluctuations generated by the ultrasonic assembly 6 and enhance liquid level stability. This energy-absorbing structure, located on the side of the flow stabilizer 202 facing the ultrasonic assembly 6, is designed with a number of micropores or microgrooves. This structure effectively absorbs and disperses the liquid fluctuations caused by the ultrasonic waves, thereby minimizing the impact on the mother-liquid level.

[0101] Specifically, the energy-absorbing structure increases the contact area between the flow stabilizer 202 and the liquid through the design of micropores or microgrooves on its surface, thereby gradually dissipating the wave energy generated when ultrasonic vibrations are transmitted to the mother liquid. This porous or multi-grooved structure can capture and guide the wave energy caused by ultrasonic waves into the pores or grooves, thereby converting large fluctuations into tiny energy releases, thereby preventing large-scale liquid surface disturbances.

[0102] In practice, the combination of micropores and microgrooves allows the energy-absorbing structure to not only adapt to liquid fluctuations but also maintain stable energy absorption despite strong fluctuations in the mother liquor level. This design significantly reduces the interference of ultrasonic fluctuations during the separation process, resulting in a more stable liquid surface and a clearer separation between the upper clear liquid layer and the lower sediment layer.

[0103] Furthermore, through the rational configuration of the energy-absorbing structure, the flow stabilizer 202 in this embodiment provides enhanced stability under high-frequency ultrasound, ensuring a continuous and efficient separation process. The energy-absorbing structure, designed as micropores or grooves, also ensures that the structure itself does not affect the floating and adjustable function of the flow stabilizer 202, allowing it to float with changes in the mother liquor level, thereby ensuring the proper adjustment of the pressure within the second chamber 302.

[0104] Therefore, by adding an energy-absorbing structure to the flow stabilizer 202, this embodiment further optimizes the liquid level stability of the slurry mother liquor separation equipment, effectively overcomes the fluctuation problem caused by the ultrasonic effect, makes the separation effect more significant and stable, and further improves the separation efficiency and separation accuracy of the equipment.

[0105] The fifth embodiment of the present invention provides a pulp-mother-liquid separation device, and based on the previous embodiment, the first cavity 301 is provided with an air outlet window 7, and the air pressure control component 5 is provided on the air outlet window 7;

[0106] Wherein, the air pressure control component 5 includes:

[0107] Pneumatic rod 501 and pneumatic plate 502;

[0108] The pneumatic rod 501 is connected to the air outlet window 7 via an elastic member 503;

[0109] The pneumatic plate 502 is connected to the pneumatic rod 501;

[0110] The elastic member 503 provides an elastic force on the pneumatic rod 501;

[0111] The direction of the elastic force is toward the second cavity 302;

[0112] The pneumatic plate 502 is located in the second cavity 302 and forms a release gap for airflow to pass through between the pneumatic plate 502 and the air outlet window 7;

[0113] Furthermore, the pneumatic plate 502 is controlled by the pressure P in the second cavity 302 to increase or decrease the size of the release gap.

[0114] In this embodiment, the slurry-mother-liquid separation equipment further incorporates a pressure control assembly 5 in addition to the flow stabilization assembly 2 to more precisely regulate the pressure within the second chamber 302, thereby ensuring the stability of the separation process. Specifically, the first chamber 301 is provided with multiple air outlet windows 7, and the pressure control assembly 5 is installed at these air outlet windows 7 to release the gas within the chamber and regulate the pressure.

[0115] The air pressure control assembly 5 includes a pneumatic rod 501 and a pneumatic plate 502. The pneumatic rod 501 is connected to the air outlet window 7 via an elastic member 503, which provides a certain elastic force, allowing the pneumatic rod 501 and pneumatic plate 502 to adjust their displacement in response to pressure changes. The force of the elastic member 503 is directed toward the second cavity 302, ensuring that the pneumatic plate 502 is always in a position to regulate the pressure in the second cavity 302.

[0116] The pneumatic plate 502 is connected to the pneumatic rod 501 and is located in the second cavity 302. A release gap is formed between the pneumatic plate 502 and the air outlet window 7 to control the outflow of gas. When the pressure P in the second cavity 302 increases, the pressure on the pneumatic plate 502 also increases accordingly, thereby reducing the displacement of the pneumatic plate 502, gradually reducing the release gap, and reducing the gas release rate. Conversely, when the pressure decreases, the release gap increases, increasing the gas outflow rate. In this way, the pneumatic plate 502 automatically adjusts the size of the release gap according to the pressure changes in the second cavity 302, achieving negative correlation control of the gas release flow rate Q and the internal pressure P.

[0117] In this embodiment, the elastic member 503 provided on the pneumatic plate 502 and the automatically adjustable release gap design maintain a stable pressure within the second chamber 302 under varying pressure conditions. This air pressure control ensures that the force applied to the flow stabilizing plate 202 remains stable even when the liquid level rises or fluctuations intensify, thereby effectively suppressing liquid level fluctuations. Furthermore, by controlling the size of the release gap, excessively rapid gas release as pressure increases is avoided, ensuring that the flow stabilizing assembly 2 maintains its support for the mother liquid level.

[0118] This design of the air pressure control component 5 based on pressure regulation not only improves the liquid level stability during the separation process, but also enables the pneumatic plate 502 to adaptively adjust the gas flow according to real-time pressure changes, thereby further improving the effect and accuracy of slurry mother liquor separation and solving the problem of unstable gas release caused by pressure changes.

[0119] The sixth embodiment of the present invention provides a pulp-mother-liquid separation device. Based on the previous embodiment, in the width direction of the device body 1, the size of the pneumatic plate 502 is L1, the size of the second cavity 302 is L2, and the following conditions are met:

[0120] L1=K*L2, the value range of K is 0.6 to 0.8.

[0121] In this embodiment, the slurry-mother-liquid separation equipment further optimizes the size design of the pneumatic plate 502 to enhance the air pressure control effect and ensure the support stability of the flow stabilization component 2. Specifically, the pneumatic plate 502 is designed with a specific size ratio in the width direction of the equipment body 1, so that the size L1 of the pneumatic plate 502 and the width L2 of the second cavity 302 satisfy the following relationship:

[0122] L1=K×L2. The value range of the proportional coefficient K is 0.6 to 0.8. The size ratio setting is optimized based on the force and pressure regulation requirements of the pneumatic plate 502 in the second cavity 302.

[0123] By designing the width of the pneumatic plate 502 to be 60% to 80% of the width of the second chamber 302, the pneumatic plate 502 has sufficient surface area under varying pressures to maintain appropriate control of gas release. A smaller K value (e.g., 0.6) effectively reduces the gas release flow rate under high pressure, allowing the pneumatic plate 502 to better suppress liquid level fluctuations under high pressure. A larger K value (e.g., 0.8) increases the gas flow area under low pressure, allowing for greater gas release and rapid adjustment when the pressure in the second chamber 302 decreases.

[0124] With this optimized design, the pneumatic plate 502 can more sensitively respond to pressure changes within the second chamber 302, achieving precise release gap adjustment and avoiding release fluctuations caused by unstable pressure. This optimized size not only ensures the support of the pneumatic plate 502 on the flow stabilization assembly 2, but also further enhances the stability and flexibility of the separation device during mother liquor level adjustment.

[0125] Therefore, by optimizing the size ratio of the pneumatic plate 502 in the width direction, this embodiment achieves more precise gas release control and higher flow stabilization effect, ensuring a smoother separation process of the slurry mother liquor under different pressure conditions, thereby improving the overall separation efficiency and operational reliability of the equipment.

[0126] The seventh embodiment of the present invention provides a slurry-mother-liquid separation device, and based on the previous embodiment, the liquid inlet component 4 includes:

[0127] Liquid inlet cavity 401 and liquid inlet pipe 402;

[0128] The liquid inlet cavity 401 is provided on the side wall of the device body 1 and is located on one side of the first cavity 301;

[0129] There are N liquid inlet pipes 402, and the N liquid inlet pipes 402 have height differences;

[0130] The liquid inlet cavity 401 is connected to the first cavity 301 through the liquid inlet pipe 402 .

[0131] In this embodiment, the slurry-mother-liquid separation equipment further optimizes the design of the liquid inlet assembly 4 to ensure that the mother liquor can enter the first chamber 301 in an orderly manner and maintain a stable liquid level during the static process. Specifically, the liquid inlet assembly 4 includes a liquid inlet chamber 401 and a plurality of liquid inlet pipes 402. Through this multi-pipe design, the mother liquor can be sequentially injected into the first chamber 301 at different heights.

[0132] The liquid inlet chamber 401 is provided on the side wall of the device body 1, on one side of the first chamber 301, and is used to store and distribute the mother liquid entering the first chamber 301. There are N liquid inlet pipes 402, which are distributed along the height of the device body 1, so that each liquid inlet pipe 402 has a certain height difference from the liquid level in the first chamber 301.

[0133] This height difference design allows the mother liquid to sequentially enter the first chamber 301 through the lower inlet pipes 402. As the liquid level in the first chamber 301 rises, the mother liquid gradually flows in through the higher inlet pipes 402. This inlet method ensures the stability of the mother liquid during the static process, preventing drastic fluctuations in the liquid level caused by single-point inlet, thereby helping to improve the separation effect.

[0134] During the liquid inlet process, as the liquid level gradually rises, the mother liquid enters through different liquid inlet pipes 402 in sequence according to the height difference. This not only controls the liquid inlet speed and flow rate, but also effectively prevents the liquid level from being disturbed by excessively rapid injection of the mother liquid, which could affect the stability of the flow stabilization assembly 2. In this way, the liquid level can be maintained uniform and stable during the separation process, which helps maintain a clear interface between the upper clear liquid layer and the lower sediment layer.

[0135] Therefore, through the design of multiple liquid inlet pipes 402 in this embodiment, the slurry mother liquor separation equipment realizes the gradual liquid inlet and stable injection of the mother liquor, reduces the interference of liquid level fluctuations on the separation process, ensures the uniform distribution and stable static state of the mother liquor in the first cavity 301, and further improves the separation effect and the operating stability of the equipment.

[0136] The eighth embodiment of the present invention provides a slurry-mother-liquid separation device, and based on the previous embodiment, includes an exhaust assembly 8 , which is arranged in the liquid inlet cavity 401 and located on the upper wall of the liquid inlet cavity 401 .

[0137] In this embodiment, the slurry-mother-liquid separation equipment adds an exhaust assembly 8 to the liquid inlet assembly 4 to further optimize pressure balance and fluid flow efficiency during the liquid inlet process. The exhaust assembly 8 is mounted on the upper wall of the liquid inlet cavity 401 and is used to effectively exhaust excess gas within the cavity during the liquid inlet process.

[0138] Specifically, when the mother liquid is injected into the first cavity 301 through the liquid inlet pipe 402, gas may accumulate within the liquid inlet cavity 401. Especially when multiple layers of liquid inlet pipes 402 are used for layer-by-layer injection, the retention of gas within the cavity may affect the flow rate and flow stability of the mother liquid, thereby affecting the smooth control of the liquid level. The exhaust assembly 8 provided on the upper wall automatically exhausts the trapped gas during the mother liquid injection process, preventing the internal cavity pressure from increasing and ensuring a smooth liquid injection process.

[0139] The design of the exhaust component 8 can release the excess gas in the liquid inlet cavity 401 in real time, which helps to maintain the smoothness of the liquid inlet flow and avoid liquid flow fluctuations and unevenness caused by gas accumulation.

[0140] Therefore, by adding the exhaust assembly 8 to the liquid inlet chamber 401, this embodiment effectively prevents gas accumulation from interfering with the liquid flow during the inlet process, improves the stability and continuity of the mother liquid entering the first chamber 301, and further enhances the stable control of the liquid level and the separation effect during the separation process. The addition of the exhaust assembly 8 significantly improves the operating efficiency and reliability of the equipment, making the liquid inlet and separation processes of the slurry mother liquid separation equipment more efficient.

[0141] The ninth embodiment of the present invention provides a slurry-mother-liquid separation device, and based on the previous embodiment, includes a floating adjustment member 9;

[0142] Wherein, the floating adjustment member 9 is provided on the flow stabilizing plate 202;

[0143] The floating adjustment member 9 is configured to adjust the weight m of the flow stabilizer 202 .

[0144] In this embodiment, the slurry-mother-liquid separation equipment incorporates a floating adjustment member 9 in addition to the flow stabilization assembly 2. This member is used to further adjust the buoyancy and balance performance of the flow stabilization plate 202, thereby optimizing the liquid level stability during the separation process. The floating adjustment member 9 is mounted on the flow stabilization plate 202 and can flexibly control its floating state by adjusting the weight m of the flow stabilization plate 202.

[0145] Specifically, the floating adjustment member 9 adjusts the weight of the flow stabilizer 202 based on fluctuations in the mother liquid level, ensuring optimal buoyancy and position under varying liquid level and pressure conditions. For example, when the mother liquid level is high, the floating adjustment member 9 can increase the weight of the flow stabilizer 202, strengthening its pressure on the liquid surface, ensuring a stable liquid level and reducing fluctuations caused by the rising liquid level. Conversely, when the liquid level drops, the floating adjustment member 9 reduces the weight of the flow stabilizer 202, allowing it to more flexibly adjust its position in response to liquid level fluctuations, thereby maintaining pressure balance within the chamber.

[0146] Through the dynamic regulation of the floating adjustment member 9, the flow stabilizer 202 can better cope with fluctuations in the mother liquid level, effectively enhancing the stabilization effect of the flow stabilization component 2 on the liquid level. This weight adjustment mechanism ensures the separation efficiency of the equipment under different operating conditions. Especially in the case of large liquid level fluctuations, the floating adjustment member 9 can provide additional flow stabilization support through weight control, enhancing the clarity and stability of the liquid surface.

[0147] Therefore, this embodiment achieves precise control of the weight of the flow stabilizer 202 by adding a floating adjustment part 9 to the flow stabilizer 202, making the liquid level fluctuation in the separation process more controllable, effectively improving the operating stability and separation effect of the equipment, and further optimizing the overall performance of the slurry mother liquor separation equipment.

[0148] The tenth embodiment of the present invention provides a slurry-mother-liquid separation device, and based on the previous embodiment, the floating adjustment member 9 includes:

[0149] a regulating cavity connected to a surface of the flow stabilizing plate 202 facing the second cavity 302;

[0150] The regulating cavity is filled with a regulating medium to adjust the weight m of the flow stabilizing plate 202 .

[0151] In this embodiment, the slurry-mother-liquid separation equipment further optimizes the design of the floating adjustment member 9 by providing an adjustment chamber to control the weight m of the flow stabilizer 202. The adjustment chamber is installed on the side of the flow stabilizer 202 facing the second chamber 302 and dynamically adjusts the weight of the flow stabilizer 202 by filling it with an adjustment medium, thereby achieving flexible control of the buoyancy of the flow stabilizer 202.

[0152] Specifically, the regulating medium in the regulating chamber can be a gas, liquid, or other suitable substance, and its filling volume can be adjusted according to changes in the mother liquid level and the pressure within the device. For example, when the weight of the flow stabilizer 202 needs to be increased to exert greater pressure on the liquid surface, the amount of regulating medium in the regulating chamber can be increased to make the flow stabilizer 202 more stable. Conversely, when the weight of the flow stabilizer 202 needs to be reduced to enhance its buoyancy, the amount of regulating medium can be reduced to make the flow stabilizer 202 lighter and more convenient for fine-grained height adjustments as the liquid level fluctuates.

[0153] Through this design of the adjustment chamber, the flow stabilizer 202 in this embodiment can more adaptively adjust its weight, thereby providing more flexible floating and more precise liquid level stabilization control. This design is particularly suitable for situations where the mother liquid level fluctuates significantly. By adjusting the weight of the flow stabilizer 202, the liquid level can be stabilized, ensuring a clear and stable separation interface and preventing fluctuations from affecting the separation effect.

[0154] Therefore, this embodiment achieves more flexible buoyancy and pressure regulation of the flow stabilizer 202 by dynamically adjusting the cavity and its filling medium, effectively improving the separation accuracy and operational stability of the slurry-mother-liquid separation equipment. This design maintains efficient operation of the equipment under varying operating conditions, further optimizing the separation equipment's adaptability and overall separation performance under variable operating conditions.
