Description

Technical Field

[0001] The invention belongs to the technical field of ore pulp treatment, relates to a technology for improving the efficiency of ore pulp mother liquid separation, and specifically relates to ore pulp mother liquid separation equipment. Background Art

[0002] Mother liquor is a common by-product of mineral processing. It usually refers to a liquid mixture containing mineral particles, impurities and other chemical components produced during the flotation, gravity separation and chemical precipitation of ore. Mother liquor generally includes two categories: acidic mother liquor and alkaline mother liquor. Its chemical properties and mineral composition depend on factors such as ore type, processing method and additives.

[0003] The separation treatment of slurry mother liquor is mainly 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 the mineral particles in the slurry mother liquor, making the upper clear liquid purer, thereby reducing the burden of subsequent process treatment and improving the recycling rate. The technology to achieve efficient separation has become one of the key technologies in the mining field.

[0004] In the prior art, physical or chemical methods are often used to improve the separation efficiency of the slurry mother liquor. For example, during the static separation process, the particles are sunk to the bottom of the container by gravity sedimentation to form a supernatant. However, for fine particles and dissolved impurities with low molecular weight, relying solely on gravity sedimentation is relatively limited, the separation efficiency is not high, and a long separation time is required. Therefore, more and more separation equipment introduces ultrasonic components, which promote particle agglomeration, crushing and accelerated sedimentation through the cavitation effect of ultrasound to achieve the effect of enhanced separation. The addition of ultrasound significantly shortens the separation time to a certain extent and improves the removal rate of suspended particles in the slurry mother liquor.

[0005] However, while the application of ultrasonic components improves separation efficiency, it also brings some problems. First, when ultrasonic waves act on the slurry mother liquor, they will produce significant fluctuations on the liquid surface, forming strong disturbances inside the liquid, resulting in instability of the separation interface of the mother liquor. The fluctuation of the liquid surface not only affects the stability of the separation process, but also leads to unclear separation between the liquid surface and the solid-liquid interface, and it is impossible to form a stable upper clear liquid and lower sediment, thereby reducing the separation effect. In addition, excessive liquid surface fluctuations may cause the settled particles to re-suspend, further affecting the separation efficiency. Summary of the invention

[0062] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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 creative work 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] A device body 1, wherein 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] Wherein, the first cavity 301 is connected to a 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 uses the flow stabilizing component 2 to achieve effective control of liquid level fluctuations. Specifically, the cavity formed by the equipment body 1 is separated into a first cavity 301 and a second cavity 302 that are independent of each other by the flow stabilizing component 2 that is slidably arranged. Among them, the first cavity 301 is connected to the liquid inlet component 4, which is used to provide a stationary area for the mother liquid to ensure that the mother liquid can be fully stationary, reduce the disturbance of suspended particles and facilitate particle sedimentation.

[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, and balance the pressure changes inside 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 during the entire separation process and avoids drastic fluctuations in the liquid level. Specifically, the slurry mother liquid separation equipment further ensures the stable state of the liquid level during the separation process through the contact between the flow stabilizing component 2 and the mother liquid level, reducing the unstable effect of the ultrasonic component 6 on the mother liquid. Specifically, the flow stabilizing component 2 forms a stable isolation layer by directly contacting the mother liquid level, so that the liquid level fluctuation 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, making the interface between the upper clear liquid and the lower sediment more stable, which 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 provided with an air pressure control component 5, which is used to automatically adjust the gas release when the internal pressure of the system changes. The gas release flow rate Q in the air pressure control component 5 is negatively correlated with the internal pressure P of the second cavity 302, that is, the greater the pressure, the less the gas release amount, and maintaining the high pressure stability in the cavity helps to enhance the suppression effect of the flow stabilizing component 2 on the liquid surface, thereby reducing the amplitude of the liquid surface fluctuation under the action of ultrasound. Specifically, the air pressure control component 5 makes the gas release flow rate Q negatively correlated with the internal pressure P of the second cavity 302, so as to better cooperate with the stabilizing effect of the flow stabilizing component 2 on the liquid surface. The reason why the gas release amount is designed to be negatively correlated with the cavity pressure is that as the mother liquid level in the first cavity 301 gradually rises, the volume and weight of the mother liquid increase, and the fluctuation effect on the ultrasonic component 6 also increases accordingly. This liquid surface fluctuation will become more intense under the action of ultrasound. If it is not effectively controlled, the liquid surface stability will be seriously affected.

[0075] To this end, the volume of the second cavity 302 is dynamically compressed by the floating flow stabilizing component 2, so that the internal pressure of the second cavity 302 increases synchronously. In this case, if the gas is released too quickly, the pressure of the second cavity 302 will drop rapidly, and it will be impossible to provide a stable support pressure for the flow stabilizing component 2. Therefore, the gas release flow rate Q is designed to be negatively correlated with the internal pressure P, so that the gas is released at a slower speed under high liquid level and high pressure conditions. This design ensures that the gas in the cavity is slowly released under a higher pressure state, thereby maintaining a moderate gas pressure in the second cavity 302.

[0076] This air pressure regulation not only provides a stable support force for the flow stabilizing component 2, but also further enhances the suppression effect of the flow stabilizing component 2 on the liquid surface when the liquid surface is high and the fluctuation is large, so that the liquid surface remains stable under the action of ultrasound. In this way, under high liquid level conditions, the flow stabilizing component 2 can more effectively suppress the fluctuation of the liquid surface, thereby making the mother liquid separation process stable and efficient, solving the problem of poor separation effect caused by the fluctuation of the liquid surface caused by ultrasound in the prior art.

[0077] The ultrasonic component 6 is installed at the bottom of the equipment body 1, facing the first cavity 301. The component uses the cavitation effect and vibration of ultrasound to promote the agglomeration and sedimentation of particles in the slurry mother liquid, 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 liquid, and the floating adjustment and air pressure control of the flow stabilization component 2 effectively suppress the liquid level fluctuation, making the separation liquid surface more stable and clear, and 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 arranged on the inner wall surface of the cavity;

[0080] A flow stabilizer 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, so as to reduce 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, so as to increase 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 disposed 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, and improve the stability and effect of the separation process.

[0083] When the liquid level of the mother liquid in the first cavity 301 rises, the flow stabilizer 202 floats up, thereby gradually reducing the volume of the second cavity 302 and compressing the gas in the cavity. This design ensures that the air pressure provides sufficient support for the flow stabilizer 202, effectively reducing the impact of fluctuations on the mother liquid. As the pressure in the second cavity 302 increases, the air pressure control component 5 will adjust the amount of gas released, so that the gas is slowly discharged, maintaining a high pressure state to provide stable support for the flow stabilizer 202, ensuring that the flow stabilizer 202 can provide greater stability when the mother liquid level is high and the fluctuation is large.

[0084] On the contrary, when the mother liquid level in the first cavity 301 decreases, the flow stabilizer 202 will sink accordingly, increasing the volume of the second cavity 302. This adjustment action reduces the cavity pressure, appropriately reduces the support force on the flow stabilizer 202, and thus releases part of the pressure under low liquid level conditions. This up and down adjustment mechanism enables the flow stabilizer component 2 to respond to changes in the mother liquid level at any time, ensuring that the gas is always within a reasonable pressure range in the second cavity 302, and avoiding interference of excessive fluctuations in the liquid level on the separation effect.

[0085] Through the design of the flow stabilizing component 2 in this embodiment, the fluctuation of the mother liquid level is effectively controlled within a reasonable range, and the separation process is more stable and efficient. The floating response of the flow stabilizing plate 202 ensures the dynamic balance of gas release and cavity pressure, especially when the liquid level rises or falls, it can achieve good pressure adaptation, thereby greatly improving the separation effect of the slurry mother liquid, and overcoming the problem of poor separation effect caused by liquid level fluctuation in traditional designs.

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

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

[0088] A first plate body 2021 and a second plate body 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 body 2021 is an annular structure, and the second plate body 2022 is connected to the inner ring of the annular structure;

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

[0092] In this embodiment, the structure of the flow stabilizing plate 202 is further optimized, and the combination design of the first plate body 2021 and the second plate body 2022 is used to better adapt to the fluctuation of the mother liquid level and improve the stability and efficiency of separation. Specifically, the flow stabilizing plate 202 includes the first plate body 2021 and the second plate body 2022, and the two plates are in direct contact with the mother liquid level in the first cavity 301, thereby stabilizing the liquid level and reducing the fluctuation caused by the ultrasonic wave.

[0093] The first plate body 2021 is annular in structure and is made of hard material to enhance its rigidity and stability. As the main structure of the flow stabilizer 202, the first plate body 2021 can effectively resist the pressure change and liquid level fluctuation of the mother liquid and ensure the overall structural strength. This annular design helps the liquid to be evenly distributed around the flow stabilizer 202, thereby reducing the impact of liquid level fluctuations on the flow stabilizer component 2 and making the liquid level more stable.

[0094] The second plate 2022 is connected to the inner circle of the first plate 2021 and is made of elastic material so that it can produce appropriate deformation when the mother liquid fluctuates. The elastic design of the second plate 2022 allows it to be fine-tuned with small fluctuations in the mother liquid level, thereby absorbing part of the fluctuation energy and further reducing the impact of the liquid surface on the flow stabilizer 202. Through this elastic energy absorption effect, the second plate 2022 can effectively absorb the fluctuation energy while alleviating the impact of ultrasonic vibration on the mother liquid level.

[0095] This double-layer structure of the flow stabilizer 202 can not only provide stable support through the hard first plate 2021, but also dynamically adjust the fluctuation with the help of the elastic second plate 2022, so that the mother liquid level is more stable during the separation process, thereby improving the separation effect. When the mother liquid level fluctuates greatly, the combination of the first plate 2021 and the second plate 2022 can disperse and absorb the fluctuation energy, significantly reduce the impact on the liquid level stability, and make the interface between the upper clear liquid and the lower sediment clear and stable.

[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 arranged 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 arranged along the surface of the flow stabilizing plate 202 .

[0100] In this embodiment, the slurry mother liquid separation device further provides an energy absorption structure on the flow stabilizing plate 202 to more efficiently buffer the wave energy generated by the ultrasonic component 6 and enhance the liquid surface stability. The energy absorption structure is located on the wall surface of the flow stabilizing plate 202 facing the ultrasonic component 6 and is designed as a plurality of micropores or microgrooves, so that it can effectively absorb and disperse the liquid fluctuation caused by the ultrasonic wave, thereby reducing the impact on the mother liquid surface.

[0101] Specifically, the energy absorbing structure increases the contact area between the flow stabilizer 202 and the liquid by designing micropores or microgrooves on the surface, thereby gradually dissipating the wave energy generated when the ultrasonic vibration is transmitted to the mother liquid. This porous or multi-grooved structure can capture and guide the wave energy into the pores or grooves when the ultrasonic wave causes fluctuations, thereby converting large fluctuations into tiny energy releases to prevent large-scale liquid surface disturbances.

[0102] In actual operation, the combination of micropores and microgrooves enables the energy absorption structure to not only adapt to liquid fluctuations, but also maintain a stable energy absorption effect under the strong fluctuations of the mother liquid level. This design greatly reduces the fluctuation interference of ultrasound during the separation process, making the liquid level more stable and facilitating the clear separation of the upper clear liquid and the lower sediment interface.

[0103] In addition, through the reasonable configuration of the energy absorption structure, the flow stabilizer 202 in this embodiment can provide higher stability under the action of high-frequency ultrasound, ensuring that the separation process is continuous and efficient. The energy absorption structure is designed as micropores or microgrooves, so that the structure itself does not affect the floating adjustment function of the flow stabilizer 202, and it can still float when the mother liquid level changes, thereby ensuring the reasonable adjustment of the pressure in the second cavity 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 comprises:

[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] Wherein, 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 device is further provided with an air pressure control component 5 on the basis of the flow stabilizing component 2 to more accurately adjust the pressure in the second cavity 302, thereby ensuring the stability of the separation process. Specifically, the first cavity 301 is provided with a plurality of air outlet windows 7, and the air pressure control component 5 is installed at the air outlet windows 7 to achieve the release and pressure regulation of the gas in the cavity.

[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 through an elastic member 503, which provides a certain elastic force so that the pneumatic rod 501 and the pneumatic plate 502 can be displaced and adjusted as the pressure changes. The force direction of the elastic member 503 points to the second cavity 302 to ensure that the pneumatic plate 502 is always in a position to adjust the pressure of the second cavity 302.

[0116] The pneumatic plate 502 is connected to the pneumatic rod 501, and is located in the second cavity 302, and 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, so that the displacement of the pneumatic plate 502 decreases, the release gap gradually decreases, and the release speed of the gas decreases. Conversely, when the pressure decreases, the release gap increases, so that the gas outflow speed increases. In this way, the pneumatic plate 502 automatically adjusts the size of the release gap according to the pressure change in the second cavity 302, and realizes the negative correlation control of the gas release flow Q and the internal pressure P.

[0117] In this embodiment, the elastic member 503 and the design of automatically adjusting the release gap provided on the pneumatic plate 502 can maintain a stable pressure in the second cavity 302 under different pressure conditions. This air pressure control allows the flow stabilizing plate 202 to always maintain a stable force when the liquid level rises or the fluctuation intensifies, thereby providing an effective suppression effect on the liquid level fluctuation. At the same time, by controlling the size of the release gap, the gas is prevented from being released too quickly when the pressure increases, ensuring the support effect of the flow stabilizing component 2 on 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 rate according to real-time pressure changes, thereby further improving the effect and accuracy of slurry mother liquid 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, and 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 satisfied:

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

[0121] In this embodiment, the size design of the pneumatic plate 502 of the slurry-mother-liquid separation device is further optimized to improve 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 device 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 cavity 302, it is ensured that the pneumatic plate 502 has sufficient bearing area under different pressure conditions to maintain appropriate gas release control. A smaller K value (such as 0.6) can effectively reduce the gas release flow rate under high pressure, so that the pneumatic plate 502 can better suppress liquid level fluctuations when the pressure is high. A larger K value (such as 0.8) increases the gas flow area under low pressure, which is suitable for releasing more gas, so as to quickly adjust when the pressure of the second cavity 302 decreases.

[0124] Under the optimized design of this size ratio, the pneumatic plate 502 can respond more sensitively to the change of pressure in the second cavity 302, realize accurate release gap adjustment, and avoid release fluctuation caused by unstable pressure. This size optimization not only ensures the support role of the pneumatic plate 502 on the flow stabilizing component 2, but also further enhances the stability and flexibility of the separation device during the mother liquid level adjustment process.

[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] A liquid inlet cavity 401 and a liquid inlet pipe 402;

[0128] The liquid inlet cavity 401 is disposed 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 a height difference;

[0130] The liquid inlet cavity 401 is in communication with the first cavity 301 through the liquid inlet pipe 402 .

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

[0132] The liquid inlet cavity 401 is arranged on the side wall of the device body 1, located on one side of the first cavity 301, and is used to store and distribute the mother liquid entering the first cavity 301. The number of liquid inlet pipes 402 is N, and these liquid inlet pipes 402 are distributed along the height direction of the device body 1, so that each liquid inlet pipe 402 has a certain height difference with the liquid level of the first cavity 301.

[0133] Through this height difference design, the mother liquid can enter the first cavity 301 through the lower liquid inlet pipe 402 in sequence, and as the liquid level in the first cavity 301 rises, the mother liquid gradually flows in through the higher liquid inlet pipe 402. This liquid inlet method ensures the stability of the mother liquid during the static process, prevents the liquid level from causing drastic fluctuations due to single-point liquid inlet, and thus helps 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, which can not only control the liquid inlet speed and flow rate, but also effectively prevent the liquid level from being disturbed due to the mother liquid being injected too quickly, thereby affecting the stability of the flow stabilizing component 2. In this way, the liquid level can be maintained uniform and stable during the separation process, which is conducive to keeping the stratified interface between the upper clear liquid and the lower sediment clear.

[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, comprises an exhaust assembly 8 , which is arranged in the liquid inlet cavity 401 and located on the upper wall surface of the liquid inlet cavity 401 .

[0137] In this embodiment, the slurry mother liquid separation device adds an exhaust component 8 on the basis of the liquid inlet component 4 to further optimize the pressure balance and fluid flow efficiency during the liquid inlet process. The exhaust component 8 is installed on the upper wall of the liquid inlet cavity 401 to effectively exhaust the excess gas inside 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 accumulation may occur inside the liquid inlet cavity 401. Especially when the multi-layer liquid inlet pipe 402 is injected layer by layer, the retention of gas in the cavity may affect the flow speed and flow stability of the mother liquid, thereby affecting the smooth control of the liquid level. The exhaust component 8 arranged on the upper wall can automatically discharge the retained gas during the mother liquid injection process, prevent the pressure inside the cavity from increasing, and ensure the smoothness of the 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 cavity 401, the present embodiment effectively avoids the interference of gas accumulation on the liquid flow during the liquid inlet process, improves the stability and continuity of the mother liquid entering the first cavity 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 process 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 arranged on the floating plate;

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

[0144] In this embodiment, the slurry mother liquid separation device adds a floating adjustment member 9 on the basis of the flow stabilizing component 2, which is used to further adjust the buoyancy and balance performance of the floating plate, thereby optimizing the liquid surface stability of the device during the separation process. The floating adjustment member 9 is arranged on the floating plate, and its floating state can be flexibly controlled by adjusting the weight m of the floating plate.

[0145] Specifically, the floating adjustment member 9 can adjust the weight of the floating plate according to the fluctuation of the mother liquid level, so that it can maintain the best buoyancy and position under different liquid level heights and pressure conditions. For example, when the mother liquid level is high, the floating adjustment member 9 can increase the weight of the floating plate to enhance its pressure on the liquid level, ensure that the liquid level remains stable, and reduce the fluctuation interference caused by the increase in the liquid level. On the contrary, when the liquid level decreases, the floating adjustment member 9 can reduce the weight of the floating plate, making it easier to flexibly adjust its position with the fluctuation of the liquid level and maintain the pressure balance in the cavity.

[0146] Through the dynamic regulation of the floating adjustment member 9, the floating plate can better cope with the fluctuation of the mother liquid level, effectively improving the stabilizing effect of the flow stabilizing component 2 on the liquid level. This weight adjustment mechanism ensures the separation efficiency of the equipment under different working conditions. Especially when the liquid level fluctuates greatly, the floating adjustment member 9 can provide additional flow stabilizing support through weight control, enhancing the clarity and stability of the liquid surface interface.

[0147] Therefore, this embodiment achieves precise control of the weight of the floating plate by adding a floating adjustment member 9 to the floating plate, 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] an adjusting cavity connected to a surface of the floating plate facing the second cavity 302;

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

[0151] In this embodiment, the slurry mother liquid separation equipment further optimizes the design of the floating adjustment member 9, and realizes the control of the weight m of the floating plate by setting an adjustment cavity. The adjustment cavity is installed on the side surface of the floating plate facing the second cavity 302, and dynamically adjusts the weight of the floating plate by filling the adjustment medium, thereby realizing flexible control of the buoyancy of the floating plate.

[0152] Specifically, the regulating medium in the regulating cavity can be gas, liquid or other suitable substances, and the filling amount can be increased or decreased in time according to the changes in the mother liquid level and the pressure in the equipment. For example, when the weight of the floating plate needs to be increased to exert greater pressure on the liquid surface, the filling amount of the regulating medium in the regulating cavity can be increased to make the floating plate more stable; and when the weight of the floating plate needs to be reduced to enhance its flexible floating performance, the filling amount of the regulating medium can be reduced to make the floating plate lighter and convenient for fine height adjustment with the fluctuation of the liquid surface.

[0153] Through the design of the adjustment cavity, the floating plate in this embodiment can adjust the weight more adaptively, thereby providing more flexible floating and more precise liquid level stability control. This design is particularly suitable for achieving steady flow suppression of the liquid surface by adjusting the weight of the floating plate when the mother liquid level fluctuates greatly, ensuring a clear and stable separation interface and avoiding the separation effect being affected by fluctuations.

[0154] Therefore, this embodiment makes the buoyancy and pressure regulation of the floating plate more flexible by adjusting the dynamic control of the cavity and its filling medium, effectively improving the separation accuracy and operation stability of the slurry mother liquid separation equipment. This design can maintain the efficient operation of the equipment under different operating conditions, and further optimizes the adaptability and overall separation effect of the separation equipment under variable working conditions.
