Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of ore pulp processing, and relates to a technology for improving the separation efficiency of ore pulp mother liquor, in particular to an ore pulp mother liquor separation device. BACKGROUND

[0002] Ore pulp mother liquor is a common byproduct of mineral processing, usually referring to the liquid mixture containing mineral particles, impurities and other chemical components generated in the processing of ore flotation, gravity separation, chemical precipitation and the like. The ore pulp mother liquor generally includes two categories: acidic ore pulp mother liquor and alkaline ore pulp mother liquor, and its chemical properties and mineral components depend on factors such as ore type, processing method and additives.

[0003] The separation treatment of ore pulp mother liquor is mainly to realize solid-liquid separation, remove the suspended mineral particles and impurities therein, and meet the environmental discharge standards or further processing requirements. An effective separation process can settle the mineral particles in the ore pulp mother liquor, so that the supernatant is more pure, thereby reducing the burden of subsequent process treatment and improving the recycling rate. The technology for realizing efficient separation has become one of the key technologies in the mining industry.

[0004] In the prior art, physical or chemical methods are often used to improve the separation efficiency of ore pulp mother liquor. For example, in the process of static separation, particles are settled to the bottom of the container by gravity settling to form supernatant. However, for fine particles and low molecular weight dissolved impurities, the effect of gravity settling alone is limited, the separation efficiency is not high, and a long separation time is required. Therefore, more and more separation devices introduce ultrasonic components to promote particle agglomeration, breakage and accelerated settling through the cavitation effect of ultrasonic waves, so as to achieve the effect of intensifying separation. The addition of ultrasonic waves significantly shortens the separation time to some extent and improves the removal rate of suspended particles in the ore pulp mother liquor.

[0005] However, the application of ultrasonic components in improving the separation efficiency also brings some problems. First, when the ultrasonic wave acts on the ore pulp mother liquor, it will produce significant fluctuation on the liquid surface, form strong disturbance in the liquid, and cause the separation interface of the mother liquor to be unstable. The fluctuation of the liquid surface not only affects the stability of the separation process, but also causes the separation of the liquid surface and the solid-liquid interface to be unclear, so that a stable supernatant and subsoil cannot be formed, thereby reducing the separation effect. In addition, excessive fluctuation of the liquid surface may cause the settled particles to be resuspended, further affecting the separation efficiency. SUMMARY

DETAILED DESCRIPTION

[0062] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0063] Please refer to Figures 1 to 6 The specific embodiments provided by the present application are as follows:

[0064] As Figures 1 to 4 shown, the first embodiment of the present application provides a mineral pulp mother liquor separation device, comprising:

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

[0066] The steady flow assembly 2 is slidingly arranged in the cavity;

[0067] The steady flow assembly 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 with the liquid inlet assembly 4, and a mother liquor standing area is provided;

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

[0070] The second cavity 302 is provided with an air pressure control assembly 5, which is configured to release the gas in the second cavity 302, and the gas release flow Q is negatively correlated with the pressure P in the second cavity 302;

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

[0072] In the present embodiment, the ore pulp mother liquor separation device utilizes the steady flow assembly 2 to effectively control the liquid level fluctuation. Specifically, the cavity formed by the device body 1 is divided into a first cavity 301 and a second cavity 302 by the sliding steady flow assembly 2. Among them, the first cavity 301 is connected to the liquid inlet assembly 4, which is used to provide a static area for the mother liquor to ensure that the mother liquor can be fully static, reduce the disturbance of suspended particles and facilitate particle sedimentation.

[0073] The design of the steady flow assembly 2 enables it to float along the axis of the device body 1 according to the liquid level height of the mother liquor in the first cavity 301, and to 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 steady flow assembly 2 floats up, compressing the volume of the second cavity 302; conversely, when the liquid level drops, the steady flow assembly 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, avoiding the violent fluctuation of the liquid level. Specifically, the ore pulp mother liquor separation device further ensures the stable state of the liquid level during the separation process through the contact of the steady flow assembly 2 with the mother liquor liquid level, reducing the unstable influence of the ultrasonic wave assembly 6 on the mother liquor. Specifically, the steady flow assembly 2 forms a stable isolation layer by directly contacting the mother liquor liquid level, so that the liquid level fluctuation can be effectively suppressed under the ultrasonic vibration, thereby maintaining the static state of the mother liquor. This design ensures the clarity of the separation liquid level, 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 a gas pressure control assembly 5 for automatically adjusting the gas release when the internal pressure of the system changes. The gas release flow rate Q in the gas pressure control assembly 5 is negatively correlated with the internal pressure P of the second cavity 302, i.e. the greater the pressure, the less the gas release, maintaining the high pressure stability inside the cavity, which helps to enhance the suppression effect of the steady flow assembly 2 on the liquid level, thereby reducing the fluctuation amplitude of the liquid level under the action of ultrasonic waves. Specifically, the gas pressure control assembly 5 makes the gas release flow rate Q negatively correlated with the internal pressure P of the second cavity 302 to better cooperate with the stabilizing effect of the steady flow assembly 2 on the liquid level. The reason for designing the gas release amount to be negatively correlated with the cavity pressure is that as the liquid level of the mother liquor in the first cavity 301 gradually rises, the volume and weight of the mother liquor increase, and the fluctuation influence on the ultrasonic wave assembly 6 also increases. This liquid level fluctuation will become more violent under the action of ultrasonic waves, and if not effectively controlled, the liquid level stability will be seriously affected.

[0075] To this end, the second cavity 302 volume is dynamically compressed by the floating flow stabilizing component 2, so that the internal pressure of the second cavity 302 is synchronously increased. In this case, if the gas is released too fast, the pressure of the second cavity 302 will quickly drop, and the flow stabilizing component 2 cannot provide stable support pressure. Therefore, the gas release flow Q is designed to be negatively related to the internal pressure P, so that the gas is released at a slower speed under high liquid level and high pressure. This design ensures that the gas in the cavity is slowly released under high pressure, thereby maintaining a moderate gas pressure in the second cavity 302.

[0076] This gas pressure regulation not only provides 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 fluctuates greatly, so that the liquid surface remains stable under the action of ultrasonic waves. In this way, under high liquid level, the flow stabilizing component 2 can more effectively suppress the fluctuation of the liquid surface, thereby stabilizing and efficiently separating the mother liquid, and solving the problem of poor separation effect caused by liquid surface fluctuation due to ultrasonic waves in the prior art.

[0077] The ultrasonic wave component 6 is installed at the bottom of the device body 1 and faces the first cavity 301. This component utilizes the cavitation effect and vibration effect of ultrasonic waves to promote the agglomeration and sedimentation of particles in the ore pulp mother liquid, thereby accelerating the separation process. In this embodiment, the ultrasonic wave component 6 and the flow stabilizing component 2 work together, the ultrasonic wave accelerates the solid-liquid separation in the mother liquid, and the floating adjustment and gas pressure control of the flow stabilizing component 2 effectively suppresses the fluctuation of the liquid surface, so that the separation liquid surface is more stable and clear, and the overall separation effect is improved.

[0078] The compensation cavity (not shown in the figure) is arranged in the second cavity 302 and communicates with the second cavity 302.

[0079] The compensation cavity can be filled with a compensation medium to increase the gas pressure force on the flow stabilizing component.

[0080] In this embodiment, the compensation cavity functions by filling a compensation medium (such as gas) to increase the gas pressure force on the flow stabilizing component 2, thereby maintaining the stability of the liquid surface during the separation process under different working conditions.

[0081] The second embodiment of the utility model provides a kind of ore pulp mother liquid separation equipment, and on the basis of the first embodiment, the flow stabilizing component 2 includes:

[0082] The sliding member 201 is arranged on the inner wall surface of the cavity.

[0083] The flow stabilizing plate 202 is connected to the sliding member 201 and can float along the axis of the device body 1.

[0084] The flow stabilizing plate 202 is controlled to float up with the rising of the liquid level in the first cavity 301 to reduce the volume of the second cavity 302, and to sink down with the falling of the liquid level in the first cavity 301 to increase the volume of the second cavity 302.

[0085] In this embodiment, the flow stabilizing assembly 2 is further refined to more effectively control the liquid level stability and accurately adjust the volume of the second cavity 302. Specifically, the flow stabilizing assembly 2 is composed of a sliding member 201 arranged 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 the changes in the liquid level 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 liquor, so as to more accurately control the pressure in the second cavity 302 and the amount of gas released, thereby improving the stability and effectiveness of the separation process.

[0086] When the liquid level in the first cavity 301 rises, the flow stabilizing plate 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 gas pressure provides sufficient support to the flow stabilizing plate 202, effectively reducing the impact of fluctuations on the mother liquor. As the pressure in the second cavity 302 increases, the gas release amount is adjusted by the gas pressure control assembly 5, so that the gas is slowly released, maintaining a high pressure state to provide stable support to the flow stabilizing plate 202, ensuring that the flow stabilizing plate 202 can provide greater stability when the liquid level is high and fluctuates greatly.

[0087] Conversely, when the liquid level in the first cavity 301 falls, the flow stabilizing plate 202 sinks down, increasing the volume of the second cavity 302. This adjustment action reduces the pressure in the cavity, appropriately reducing the support force on the flow stabilizing plate 202, thereby releasing some pressure in the low liquid level condition. This up and down adjustment mechanism enables the flow stabilizing assembly 2 to respond to changes in the liquid level at any time, ensuring that the gas is always within a reasonable pressure range in the second cavity 302, avoiding the interference of large fluctuations in the liquid level on the separation effect.

[0088] Through the design of the flow stabilizing assembly 2 in this embodiment, the fluctuations of the liquid level are 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, which can achieve good pressure adaptation, thereby greatly improving the separation effect of the mother liquor of the ore slurry and overcoming the problem of poor separation effect caused by fluctuations in the liquid level in the traditional design.

[0089] In a specific embodiment, the sliding member 201 is in the form of a sliding block and a sliding groove.

[0090] AsFigures 5 to 6 The third embodiment of the utility model discloses a kind of ore pulp mother liquor separation equipment, and on the basis of last embodiment, the steady flow plate 202 includes:

[0091] First plate body 2021 and second plate body 2022;

[0092] Wherein, the first plate body 2021 and the second plate body 2022 are configured to contact with the liquid level of mother liquor in the first cavity 301;

[0093] And, the first plate body 2021 is annular structure, and the second plate body 2022 is connected to the inner ring of the annular structure;

[0094] Wherein, the first plate body 2021 is hard material, and the second plate body 2022 is elastic material.

[0095] In the embodiment, the structure of steady flow plate 202 is further optimized, and the combination design of first plate body 2021 and second plate body 2022 is used to better adapt to the fluctuation of mother liquor liquid level and improve the stability and efficiency of separation. Specifically, the steady flow plate 202 includes first plate body 2021 and second plate body 2022, and the two plate bodies are directly contacted with the liquid level of mother liquor in the first cavity 301, thereby playing the role of stabilizing liquid level and reducing the fluctuation caused by ultrasonic wave.

[0096] The first plate body 2021 is annular structure, and is made of hard material to enhance its rigidity and stability. As the main structure of steady flow plate 202, the first plate body 2021 can effectively resist the pressure change and liquid level fluctuation of mother liquor, and ensure the structural strength of the whole. This annular design helps to distribute the liquid evenly around the steady flow plate 202, thereby reducing the impact of liquid level fluctuation on the steady flow assembly 2, and making the liquid level more stable.

[0097] The second plate body 2022 is connected to the inner ring of the first plate body 2021 and is made of elastic material, so that it can produce moderate deformation when the mother liquor fluctuates. The elastic design of the second plate body 2022 allows it to fine-tune with small fluctuations of mother liquor liquid level, thereby absorbing part of the fluctuation energy and further reducing the impact force of liquid level on the steady flow plate 202. Through this elastic energy absorption effect, the second plate body 2022 efficiently absorbs fluctuation energy while relieving the influence of ultrasonic vibration on the mother liquor liquid level.

[0098] The double-layer structure of the flow stabilizing plate 202 is designed to provide stable support through the hard first plate body 2021 and to realize dynamic adjustment of fluctuations through the elastic second plate body 2022, so that the mother liquid surface is more stable during the separation process, thereby improving the separation effect. When the mother liquid surface fluctuates greatly, the combination of the first plate body 2021 and the second plate body 2022 can disperse and absorb the fluctuation energy, significantly reducing the influence on the stability of the liquid surface, so that the interface between the upper clear liquid and the lower sediment is clear and stable.

[0099] The fourth embodiment of the utility model provides a kind of ore pulp mother liquid separation equipment, and on the basis of previous embodiment, including energy absorbing structure (not shown in drawing);

[0100] The energy absorbing structure is arranged on the wall surface of the flow stabilizing plate 202 facing the ultrasonic wave assembly 6.

[0101] And, the energy absorbing structure is configured to absorb and buffer the fluctuation energy generated by the ultrasonic wave assembly 6.

[0102] The energy absorbing structure is a plurality of micropores or microgrooves arranged along the surface of the flow stabilizing plate 202.

[0103] In this embodiment, the ore pulp mother liquid separation equipment further provides an energy absorbing structure on the flow stabilizing plate 202 to more efficiently buffer the fluctuation energy generated by the ultrasonic wave assembly 6 and enhance the stability of the liquid surface. The energy absorbing structure is located on the side wall of the flow stabilizing plate 202 facing the ultrasonic wave assembly 6 and is designed as a plurality of micropores or microgrooves, so that it can effectively absorb and disperse the liquid fluctuations caused by ultrasonic waves, thereby reducing the impact on the mother liquid surface.

[0104] Specifically, the energy absorbing structure increases the contact area between the flow stabilizing plate 202 and the liquid through the design of surface micropores or microgrooves, thereby gradually dissipating the fluctuation energy generated when the ultrasonic vibration is transmitted to the mother liquid. This porous or grooved structure can capture and guide the fluctuation energy into the pores or grooves when the ultrasonic wave causes fluctuations, thereby converting large-scale fluctuations into small energy releases to prevent large-scale liquid surface disturbances.

[0105] In actual operation, the combination of micropores and microgrooves enables the energy absorbing structure to not only adapt to liquid fluctuations but also maintain stable energy absorbing effect under strong fluctuations of the mother liquid surface. This design greatly reduces the fluctuation interference of ultrasonic waves during the separation process, making the liquid surface more stable and helping to clearly separate the interface between the upper clear liquid and the lower sediment.

[0106] In addition, by reasonable configuration of the energy absorption structure, the flow stabilizing plate 202 in the embodiment can provide higher stability under the action of high-frequency ultrasonic waves, ensuring that the separation process continues and is efficient. The energy absorption structure is designed as micropores or microgrooves, which also does not affect the floating adjustment function of the flow stabilizing plate 202, and can still float with the change of the mother liquid level, thereby ensuring the reasonable adjustment of the pressure in the second cavity 302.

[0107] Therefore, by increasing the energy absorption structure on the flow stabilizing plate 202, the embodiment further optimizes the liquid level stability of the ore pulp mother liquid separation device, effectively overcomes the fluctuation problem caused by ultrasonic waves, makes the separation effect more significant and stable, and further improves the separation efficiency and separation precision of the device.

[0108] The fifth embodiment of the utility model provides a kind of ore pulp mother liquid separation equipment, and on the basis of last embodiment, the first cavity 301 is provided with air outlet 7, and the air pressure control assembly 5 is arranged in the air outlet 7;

[0109] The air pressure control assembly 5 includes:

[0110] Pneumatic rod 501 and pneumatic plate 502;

[0111] The pneumatic rod 501 is connected to the air outlet 7 by an elastic member 503;

[0112] The pneumatic plate 502 is connected to the pneumatic rod 501;

[0113] The elastic member 503 provides an elastic force to the pneumatic rod 501;

[0114] The direction of the elastic force is directed to the second cavity 302;

[0115] The pneumatic plate 502 is located in the second cavity 302, and forms a release gap for airflow between the pneumatic plate 502 and the air outlet 7;

[0116] And, the pneumatic plate 502 increases or reduces the size of the release gap under the control of the pressure P in the second cavity 302.

[0117] In the embodiment, the ore pulp mother liquid separation device further provides an air pressure control assembly 5 on the basis of the flow stabilizing assembly 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 outlets 7, and the air pressure control assembly 5 is installed at the air outlet 7 to release and adjust the pressure of the gas in the cavity.

[0118] The air pressure control assembly 5 comprises an air rod 501 and an air plate 502. The air rod 501 is connected to the air outlet window 7 through an elastic member 503, and provides a certain elastic force, so that the air rod 501 and the air plate 502 are displaced and adjusted according to the pressure change. The force direction of the elastic member 503 points to the second cavity 302, so as to ensure that the air plate 502 is always in the position for adjusting the pressure of the second cavity 302.

[0119] The air plate 502 is connected to the air rod 501, located in the second cavity 302, and forms a release gap between the air plate 502 and the air outlet window 7, which is used for controlling the outflow of the gas. When the pressure P in the second cavity 302 increases, the pressure on the air plate 502 also increases accordingly, so that the displacement of the air 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 outflow speed of the gas increases. In this way, the air 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.

[0120] In the embodiment, through the design of the elastic member 503 provided on the air plate 502 and the automatic adjustment of the release gap, the stable pressure in the second cavity 302 can be maintained under different pressure conditions. The air pressure control makes the steady flow plate 202 always maintain stable stress under the condition that the liquid level rises or the fluctuation intensifies, thereby providing effective suppression effect on the liquid level fluctuation. At the same time, by controlling the size of the release gap, the over-fast release of the gas when the pressure increases is avoided, and the support effect of the steady flow assembly 2 on the mother liquid liquid level is ensured.

[0121] The air pressure control assembly 5 based on pressure regulation not only improves the liquid level stability in the separation process, but also enables the air plate 502 to adaptively adjust the gas flow according to the real-time pressure change, thereby further improving the effect and precision of the ore pulp mother liquid separation, and solving the problem of unstable gas release caused by pressure change.

[0122] The sixth embodiment of the utility model provides a kind of ore pulp mother liquid separation equipment, and on the basis of previous embodiment, in the width direction of the equipment body 1, the size of the air plate 502 is L1, the size of the second cavity 302 is L2, and satisfy:

[0123] L1=K*L2, the value range of K is 0.6 to 0.8.

[0124] In this embodiment, the size of the air plate 502 in the pulp mother liquor separation device is further optimized to improve the air pressure control effect and ensure the support stability of the steady flow assembly 2. Specifically, the air 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 air plate 502 and the width L2 of the second cavity 302 satisfy the following relationship:

[0125] L1=K×L2. Wherein, the value range of the proportion coefficient K is 0.6 to 0.8. The size ratio is set based on the force and pressure adjustment requirements of the air plate 502 in the second cavity 302.

[0126] By designing the width of the air plate 502 as 60% to 80% of the width of the second cavity 302, it can ensure that the air plate 502 has enough bearing area under different pressure conditions to maintain appropriate gas release amount control. A smaller K value (such as 0.6) can effectively reduce the gas release flow under high pressure, so that the air plate 502 can better suppress the liquid level fluctuation when the pressure is higher. And 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.

[0127] Under the optimization design of the size ratio, the air plate 502 can more sensitively respond to the change of the pressure in the second cavity 302, realize precise release gap adjustment, and avoid release fluctuation caused by unstable pressure. This size optimization not only ensures the supporting effect of the air plate 502 on the steady flow assembly 2, but also further enhances the stability and flexibility of the separation device in the mother liquor liquid level adjustment process.

[0128] Therefore, by optimizing the size ratio of the air plate 502 in the width direction, this embodiment realizes more accurate gas release control and higher steady flow effect, ensures that the separation process of the pulp mother liquor is more stable under different pressure conditions, and improves the overall separation efficiency and operation reliability of the device.

[0129] The seventh embodiment of the utility model discloses a pulp mother liquor separation device, and on the basis of the previous embodiment, the liquid inlet assembly 4 comprises:

[0130] A liquid inlet cavity 401 and a liquid inlet pipe 402;

[0131] Among them, the liquid inlet cavity 401 is arranged on the side wall surface of the device body 1 and located on one side of the first cavity 301.

[0132] Among them, the liquid inlet pipe 402 is N, and N liquid inlet pipes 402 have height difference.

[0133] The liquid inlet cavity 401 is communicated with the first cavity 301 through the liquid inlet pipe 402.

[0134] In this embodiment, the ore pulp mother liquor separation device further optimizes the design of the liquid inlet assembly 4 to ensure that the mother liquor can enter the first cavity 301 in order and maintain a stable liquid level during the standing process. Specifically, the liquid inlet assembly 4 includes a liquid inlet cavity 401 and a plurality of liquid inlet pipes 402. Through this multi-pipe design, the mother liquor can be sequentially injected into the first cavity 301 at different heights.

[0135] Among them, the liquid inlet cavity 401 is arranged on the side wall surface of the device body 1, located on one side of the first cavity 301, used for storing and distributing the mother liquor 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 height of the first cavity 301.

[0136] Through this height difference design, the mother liquor can enter the first cavity 301 through the liquid inlet pipe 402 at the lower position in turn, and as the liquid level in the first cavity 301 rises, the mother liquor gradually flows in through the liquid inlet pipe 402 at the higher position. This liquid inlet mode ensures the stability of the mother liquor during the standing process, prevents the liquid level from causing severe fluctuations due to single-point liquid inlet, and thus helps to improve the separation effect.

[0137] During the liquid inlet process, as the liquid level gradually rises, the mother liquor enters through different liquid inlet pipes 402 in turn according to the height difference, which not only can control the liquid inlet speed and flow, but also can effectively prevent the liquid level from being disturbed due to the too fast injection of the mother liquor, affecting the stability of the stable flow assembly 2. In this way, the liquid level can be maintained uniform and stable during the separation process, which is beneficial to the clear separation of the upper clear liquid and the lower sediment.

[0138] Therefore, through the design of multiple liquid inlet pipes 402 in this embodiment, the ore pulp mother liquor separation device realizes the gradual liquid inlet and stable injection of the mother liquor, reduces the disturbance of liquid level fluctuation to the separation process, ensures the uniform distribution and stable standing state of the mother liquor in the first cavity 301, and further improves the separation effect and the running stability of the device.

[0139] The eighth embodiment of the utility model discloses a kind of ore pulp mother liquor separation devices, and on the basis of previous embodiment, including exhaust assembly 8, it is arranged in the liquid inlet cavity 401, and located the upper wall surface of the liquid inlet cavity 401.

[0140] In this embodiment, the ore pulp mother liquor separation device increases exhaust assembly 8 based on liquid inlet assembly 4, to further optimize the pressure balance and fluid flow efficiency in the liquid inlet process. The exhaust assembly 8 is installed on the upper wall surface of the liquid inlet cavity 401, for effectively exhausting excess gas inside the cavity during the liquid inlet process.

[0141] Specifically, when the mother liquor is injected into the first cavity 301 through the liquid inlet pipe 402, gas accumulation may occur inside the liquid inlet cavity 401, especially in the case of layer-by-layer injection of the multi-layer liquid inlet pipe 402. The retention of gas in the cavity can affect the flow rate and stability of the mother liquor, thereby affecting the smooth control of the liquid level. The gas exhaust assembly 8 arranged on the upper wall can automatically exhaust the retained gas during the injection of the mother liquor, prevent the internal pressure of the cavity from rising, and ensure the smoothness of the liquid inlet process.

[0142] The design of the gas exhaust assembly 8 can release the excess gas in the liquid inlet cavity 401 in real time, which helps to maintain the stability of the liquid inlet flow and avoid liquid flow fluctuations and unevenness caused by gas accumulation.

[0143] Therefore, by adding the gas exhaust assembly 8 to the liquid inlet cavity 401, the 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 liquor entering the first cavity 301, and further enhances the liquid level stability control and separation effect during the separation process. The addition of the gas exhaust assembly 8 significantly improves the operating efficiency and reliability of the equipment, making the liquid inlet and separation process of the ore pulp mother liquor separation equipment more efficient.

[0144] The ninth embodiment of the utility model provides an ore pulp mother liquor separation equipment, and on the basis of the previous embodiment, a floating adjusting part 9 is further included;

[0145] The floating adjusting part 9 is arranged on the flow stabilizing assembly 2.

[0146] The floating adjusting part 9 is configured to adjust the weight m of the flow stabilizing assembly 2.

[0147] In this embodiment, the ore pulp mother liquor separation equipment adds the floating adjusting part 9 to the flow stabilizing assembly 2, which is used to further adjust the buoyancy and balance performance of the flow stabilizing assembly 2, thereby optimizing the liquid level stability of the equipment during the separation process. The floating adjusting part 9 is arranged on the flow stabilizing assembly 2, and the weight m of the flow stabilizing assembly 2 can be adjusted to flexibly control its floating state.

[0148] Specifically, the floating adjusting part 9 can adjust the weight of the flow stabilizing assembly 2 according to the fluctuation of the mother liquor level, so that it maintains the best buoyancy and position under different liquid level heights and pressure conditions. For example, when the mother liquor level is high, the weight of the flow stabilizing assembly 2 can be increased by the floating adjusting part 9 to enhance its pressure on the liquid level, ensure the stability of the liquid level, and reduce the disturbance caused by the rising of the liquid level. On the contrary, when the liquid level is lowered, the floating adjusting part 9 can reduce the weight of the flow stabilizing assembly 2, so that it is more flexible to adjust the position with the fluctuation of the liquid level, and maintain the pressure balance in the cavity.

[0149] Through the dynamic regulation of the floating adjusting part 9, the flow stabilizing assembly 2 can better cope with the fluctuation of the mother liquid level, effectively improving the flow stabilizing effect of the flow stabilizing assembly 2 on the liquid level. This weight adjustment mechanism ensures the separation efficiency of the device under different working conditions, especially when the liquid level fluctuates greatly, the floating adjusting part 9 can provide additional flow stabilizing support through weight control, enhancing the clarity and stability of the liquid level interface.

[0150] Therefore, by adding the floating adjusting part 9 to the flow stabilizing assembly 2, the embodiment realizes precise control of the weight of the flow stabilizing assembly 2, makes the liquid level fluctuation in the separation process more controllable, effectively improves the operation stability and separation effect of the device, and further optimizes the overall performance of the ore pulp mother liquid separation device.

[0151] The tenth embodiment of the utility model discloses an ore pulp mother liquid separation device, and on the basis of the previous embodiment, the floating adjusting part 9 includes:

[0152] Adjusting cavity, connecting to the surface of the flow stabilizing assembly 2 towards the second cavity 302;

[0153] Among them, the adjusting cavity is filled with an adjusting medium to adjust the weight m of the flow stabilizing assembly 2.

[0154] In this embodiment, the ore pulp mother liquid separation device further optimizes the design of the floating adjusting part 9, and controls the weight m of the flow stabilizing assembly 2 by setting the adjusting cavity. The adjusting cavity is installed on one side surface of the flow stabilizing assembly 2 towards the second cavity 302, and the weight of the flow stabilizing assembly 2 is dynamically adjusted by filling the adjusting medium, so as to realize flexible control of the buoyancy of the flow stabilizing assembly 2.

[0155] Specifically, the adjusting medium in the adjusting cavity can be gas, liquid or other suitable substances, which can increase or decrease the filling amount in time according to the change of the mother liquid level and the pressure in the device. For example, when it is necessary to increase the weight of the flow stabilizing assembly 2 to exert greater pressure on the liquid level, the filling amount of the adjusting medium in the adjusting cavity can be increased, so that the flow stabilizing assembly 2 is more stable;When it is necessary to reduce the weight of the flow stabilizing assembly 2 to enhance its flexible floating, the filling amount of the adjusting medium can be reduced, so that the flow stabilizing assembly 2 is lighter and more convenient for fine height adjustment with the fluctuation of the liquid level.

[0156] Through the design of the adjusting cavity, the flow stabilizing assembly 2 in the embodiment can more adaptively adjust the weight, so as to provide more flexible floating and more accurate liquid level stabilizing control. This design is particularly suitable for the case where the liquid level of the mother liquid fluctuates greatly, and the weight of the flow stabilizing assembly 2 is adjusted to realize the flow stabilizing suppression on the liquid level, ensure the clear and stable separation interface, and avoid the influence of fluctuation on the separation effect.

[0157] Therefore, the embodiment adjusts the dynamic control of the cavity and the filling medium thereof, so that the buoyancy and pressure adjustment of the steady flow assembly 2 is more flexible, and the separation precision and operation stability of the ore pulp mother liquid separation device are effectively improved.
