Description

Technical Field

[0001] The invention belongs to the technical field of slurry processing, relates to a technology for improving slurry diversion efficiency, and specifically relates to a thickener distribution system. Background Art

[0002] Thickener is a kind of equipment widely used in mineral processing, metallurgy and chemical engineering, mainly used for solid-liquid separation and concentration of slurry. Through the sedimentation of thickener, the clear liquid in the slurry can be effectively removed, and the solid particles can be concentrated into a high-concentration slurry for subsequent treatment or discharge. Thickener is usually designed as a gravity sedimentation device, and the use of flocculants can improve the particle sedimentation efficiency and achieve rapid concentration.

[0003] In practical applications, the slurry concentrated in the thickener usually needs to be further processed through a shaking table device. In the prior art, the thickener usually needs to be connected to multiple shaking table devices. The positions of these shaking table devices vary in distance according to the actual production process layout, that is, some shaking table devices are far from the thickener, while others are closer. In this case, after the slurry flows out of the thickener, due to factors such as gravity, pipeline length, and resistance differences, the amount of slurry entering each shaking table device during transportation may be uneven. Specifically, it is manifested as follows:

[0004] The shaking devices at close distances receive more slurry: Due to the short pipes and small resistance, the slurry flows smoothly to the shaking devices at close distances, so these shaking devices usually receive more slurry. The shaking devices at long distances do not receive enough slurry: For the shaking devices far away from the thickening tank, due to the long pipes and large resistance, the slurry will experience a decrease in flow rate or flow before reaching these devices, resulting in the slurry received by these shaking devices being significantly insufficient.

[0005] Due to insufficient slurry supply to the distant shaking devices, these devices cannot operate at full capacity, resulting in a decrease in overall equipment utilization. In addition, the nearby shaking devices may be overloaded due to excessive slurry processing, which will accelerate equipment wear and failure rate and affect production efficiency. Uneven slurry supply not only reduces the efficiency of the shaking devices, but also causes waste of energy and resources. The distant shaking devices fail to operate at full capacity, resulting in a waste of electricity and water resources, while the nearby equipment may require more maintenance and replacement due to overload.

[0057] 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.

[0058] See also Figures 1 to 6 As shown, the specific embodiments provided by the present invention are as follows:

[0059] like Figures 1 to 3 As shown, the first embodiment of the present invention provides a thickener distribution system, comprising:

[0060] A flow splitter 2, the flow splitter 2 having a feed end and a discharge end;

[0061] The feed end is in communication with the discharge pipeline of the thickener 1;

[0062] The discharge end is provided with N diversion openings 201, which are arranged in sequence along the height direction of the diverter 2, and the height H increases in sequence;

[0063] Each of the diversion ports 201 is connected to a rocking device 3 in a one-to-one correspondence, and the horizontal distance between the rocking device 3 and the diverter 2 is L;

[0064] The height H of each of the diversion ports 201 is negatively correlated with the distance L of the corresponding shaking bed device 3 connected thereto;

[0065] The negative correlation means that the shaking table device 3 farthest from the diverter 2 is connected to the diverter port 201 set at the lowest height of the diverter 2, and the shaking table device 3 closest to the diverter 2 is connected to the diverter port 201 set at the highest height of the diverter 2.

[0066] In this embodiment, by designing the negative correlation between the height H of the diverter port 201 in the diverter 2 and the distance from the shaking table device 3, the distribution uniformity of the slurry between the shaking table devices 3 at different distances is improved to a certain extent.

[0067] Specifically, the height H of each diversion port 201 of the diverter 2 decreases as the horizontal distance L between the diverter 2 and the shaking table device 3 increases. This design aims to optimize the flow distribution of the slurry flowing to each shaking table device 3 by utilizing the liquid level difference and gravity.

[0068] For the shaking table device 3 farthest from the diverter 2 (ie, Lmax), the diverter port 201 is set at the lowest position (ie, Hmin) to ensure that the shaking table device 3 receives the slurry first. The disadvantage of the long distance is compensated by increasing the liquid level pressure, thereby ensuring the flow rate of the slurry to a certain extent.

[0069] For the shaking table device 3 closest to the diverter 2 (ie Lmin), the diverter port 201 is set at the highest point (ie Hmax), so that the slurry flows first to the equipment farther away, and then to the equipment nearby, so as to balance the slurry distribution of the whole system as much as possible.

[0070] This height and distance design can dynamically adjust the flow direction of the slurry to a certain extent and optimize the slurry receiving amount of each shaking table device 3. Although it cannot completely guarantee that all shaking table devices 3 obtain completely equal slurry volume, this design can reduce the flow difference and make the slurry supply of each device closer. The system uses the height difference to adjust the natural flow characteristics of the slurry, reduces the uneven flow caused by distance differences, and optimizes the balance of supply.

[0071] This design can reduce the uneven pulp supply problem caused by the position difference of the shaking table device 3 in the prior art to a certain extent, and improve the overall separation efficiency of the system. Each shaking table device 3 receives a relatively balanced amount of ore pulp within a reasonable range, thereby improving the utilization rate of the equipment and the processing effect.

[0072] By designing and adjusting the height of the diversion port 201, the system can maintain a certain degree of flexibility and stability under different working conditions, and minimize the imbalance problem caused by distance differences.

[0073] The thickener distribution system of this embodiment is simple in structure, mainly relying on height difference and gravity principle to achieve slurry distribution, avoiding complex mechanical or electrical control. This physical design is low-maintenance, reduces maintenance requirements during system operation, and reduces potential failure risks.

[0074] The thickener distribution system of this embodiment is not only suitable for the slurry distribution of multiple shaking table devices 3 in the mineral processing industry, but also can be applied to other process flows that require multi-point slurry distribution. By optimizing the height design of the diversion port 201, it can adapt to the requirements of different equipment layouts and improve the flow uniformity of the system to a certain extent.

[0075] Therefore, this embodiment, by reasonably designing the relationship between the height of the diversion port 201 and the distance from the shaking table device 3, alleviates the problem of uneven slurry supply caused by the distance difference in the prior art to a certain extent, and improves the efficiency and stability of the thickener distribution system. However, limited by the actual working conditions and slurry characteristics, the system ensures a relatively uniform distribution effect within a certain range.

[0076] In a specific embodiment, the flow divider 2 is a cylindrical barrel or a rectangular tank, which is used to receive the concentrated slurry from the thickener 1 .

[0077] The second embodiment of the present invention provides a thickener distribution system, and based on the first embodiment, the diameter D of each diversion port 201 is positively correlated with the horizontal distance L of the corresponding shaking table device 3 connected thereto, wherein the diameter of the diversion port 201 is adjusted according to the following formula:

[0078] Di = Dmin + k * (Lmax - Li);

[0079] Wherein, Di represents the diameter of the i-th diversion port 201, Dmin is the minimum diameter, Lmax is the maximum horizontal distance between the shaking table device 3 and the diverter 2, Li is the horizontal distance between the i-th shaking table device 3 and the diverter 2; k is the diameter adjustment coefficient, and the value range is 0.05 to 0.2.

[0080] In this embodiment, by further designing that the diameter D of each diverter port 201 is positively correlated with the horizontal distance L of the corresponding shaking table device 3, the purpose is to optimize the distribution effect of the slurry between the shaking table devices 3 at different distances. Specifically, the diameter of the diverter port 201 increases as the distance between it and the shaking table device 3 increases. This design combines the height adjustment mechanism of the diverter port 201 in the first embodiment, and improves the balance and flexibility of the slurry distribution system from multiple dimensions. According to the formula Di = Dmin + k * (Lmax-Li), the diameter Di of the diverter port 201 corresponding to the shaking table device 3 far away from the diverter 2 (that is, Li is larger) is also larger.

[0081] This design increases the supply of slurry by increasing the opening area of ​​the long-distance diversion port 201 to compensate for the flow loss caused by the long distance. The shaking table device 3 at a short distance (i.e., Li is small) corresponds to a smaller diversion port 201 diameter to prevent excessive inflow of slurry and maintain the overall balance of the system. By adjusting the diameter of the diversion port 201, the flow rate is controlled not only by the liquid level difference and height, but also by adding the parameter of diameter to further fine-tune the flow rate. In this way, even if there is a certain uncertainty in the flow of slurry (such as pipeline resistance and liquid level fluctuation), the diameter adjustment can compensate to a certain extent and reduce the flow difference between the slurry in the long and short shaking table devices 3.

[0082] Among them, the range of the diameter adjustment coefficient k is set to 0.05 to 0.2. Such an adjustment range not only ensures the flexibility of the diameter change of the diverter port 201, but also prevents the negative impact of too large or too small adjustment range on the system. By incorporating the height and diameter of the diverter port 201 into the adjustment range at the same time, this embodiment can more effectively reduce the uneven supply of slurry caused by the distance difference of the shaking table device 3, and improve the uniformity of the distribution of slurry between the shaking table devices 3 to a certain extent. Even in the case of fluctuations in slurry flow rate or concentration, this multi-parameter adjustment mechanism can still maintain a high system adaptability and flexibility.

[0083] The third embodiment of the present invention provides a thickener distribution system, and based on the previous embodiment, the height H of the diversion port 201 and the distance L between the diversion port 201 and the corresponding shaking table device 3 satisfy:

[0084] Hi=Hmax-m*(Lmax-Li);

[0085] Among them, Hi represents the height of the i-th diversion port 201, Hmax is the maximum height of the diversion port 201, that is, the height of the diversion port 201 corresponding to the shaking table closest to the diverter 2, Lmax is the maximum horizontal distance between the shaking table device 3 and the diverter 2, Li is the horizontal distance between the i-th shaking table device 3 and the diverter 2, m is the height adjustment coefficient, and the value range is 0.1 to 0.5.

[0086] In this embodiment, by introducing the adjustment relationship between the height H of the diverter port 201 and the distance L of the corresponding shaking table device 3 connected thereto, the distribution balance of the slurry is further optimized. Specifically, the height of the diverter port 201 is adjusted according to the formula Hi=Hmax-m*(Lmax-Li), so that the height of the diverter port 201 decreases as the horizontal distance of the shaking table device 3 increases. This design, based on the previous embodiment, achieves more accurate control of the slurry flow rate through height difference adjustment.

[0087] According to the formula, when the shaking table device 3 is far away from the diverter 2 (ie, Li is large), the height Hi of the diverter port 201 is low, thereby utilizing the liquid level difference to increase flow compensation and ensure that the remote shaking table device 3 can receive sufficient slurry.

[0088] On the contrary, when the shaking table device 3 is closer to the diverter 2 (i.e., Li is smaller), the height Hi of the diverter port 201 is higher, so that the slurry flows to the shaking table device 3 at a distance first, and then flows to the nearby equipment. This design combines the function of diameter adjustment in the previous embodiment, and further improves the balance of flow.

[0089] This embodiment combines the dual adjustment of diameter and height: diameter adjustment differentiates the size of the diversion port 201 of the far and near shaking table device 3, and height adjustment optimizes the flow distribution by utilizing the liquid level difference. Through the dual adjustment of height and diameter, the system realizes the dynamic balanced distribution of the slurry.

[0090] The value range of the height adjustment coefficient m is 0.1 to 0.5, ensuring that the height change is moderate, so that the diversion effect is stable. This range of adjustment coefficients can adapt to the working conditions of different flow rates and slurry concentrations.

[0091] This embodiment further refines the slurry distribution by adjusting the height, while ensuring the change of the diameter of the diversion port 201 in the above embodiment. In this way, even if the pipeline resistance and distance are greatly different, the system can still ensure that the slurry amount received by the far and near shaking table devices 3 is relatively uniform to a certain extent.

[0092] By utilizing the height difference to perform flow compensation, the slurry can be automatically distributed according to the position of each shaking table device 3, further enhancing the stability of the system and the uniformity of the slurry distribution.

[0093] The dual adjustment of height and diameter enables the system to automatically achieve a balanced distribution of the slurry according to the distance of the shaking table device 3, and dynamic adjustment of the slurry supply can be achieved without additional mechanical or electrical control devices.

[0094] Through the combined adjustment of the height and the diameter, this embodiment further improves the balance of the slurry distribution on the basis of the previous embodiment, reduces the uneven supply phenomenon caused by the difference in distance and pipeline resistance, and improves the separation efficiency of the shaking table device 3.

[0095] like Figures 4 to 6 As shown, the fourth embodiment of the present invention proposes a thickener distribution system, and based on the previous embodiment, comprises:

[0096] Adjustment device 4;

[0097] The regulating device 4 is disposed below each of the diversion ports 201;

[0098] The regulating device 4 located below the Nth diversion port 201, when controlled by the gravity of the concentrated slurry as a force, regulates the opening of the N-1th diversion port 201 adjacent thereto.

[0099] In this embodiment, by adding the regulating device 4, each diversion port 201 can be dynamically adjusted according to the actual slurry flow demand, thereby further improving the uniformity of slurry distribution. Specifically, the regulating device 4 is installed below each diversion port 201. When the concentrated slurry liquid level reaches a certain diversion port 201 (the Nth diversion port 201), under the action of the gravity of the concentrated slurry, the regulating device 4 will automatically control the opening of the adjacent diversion port 201 (the N-1th diversion port 201) to prevent excessive slurry from flowing into the adjacent N-1 shaking table devices 3. This design ensures the reasonable distribution of slurry to a certain extent, and prevents uneven equipment load caused by excessive slurry entering, thereby affecting the separation effect.

[0100] By automatically controlling the opening of each diversion port 201 by the adjusting device 4, the amount of slurry received by each shaking table device 3 can be adjusted according to the change in the gravity of the slurry. This design can play a compensatory role in the case of distance difference, slurry concentration change or system flow fluctuation, thereby achieving flow balance to a certain extent.

[0101] This embodiment combines the height adjustment and diameter adjustment in the above-mentioned embodiments, and realizes multi-level flow control through the gravity-sensing adjustment device 4. The height difference, diameter difference and dynamic opening adjustment cooperate with each other to ensure that the slurry can be stably and continuously supplied to each shaking table device 3, further reducing the uneven distribution problem caused by flow difference.

[0102] The fifth embodiment of the present invention provides a thickener distribution system, and based on the previous embodiment, the adjustment device 4 includes:

[0103] A flow guide component 401 and a control component 402;

[0104] The inlet end of the flow guide component 401 is located below the Nth flow diversion port 201;

[0105] The outlet end of the flow guide component 401 is located at the upper end of the N-1th flow diversion port 201;

[0106] The control component 402 is located below the outlet end of the flow guide component 401;

[0107] The guide assembly 401 has a support platform 4011 for supporting the concentrated slurry and transferring its gravity to the control assembly 402;

[0108] The control component 402 is connected to the support platform 4011 and is configured to adjust the opening of the N-1th diversion port 201 according to the gravity change of the concentrated slurry.

[0109] In this embodiment, by introducing the combined structure of the flow guide component 401 and the control component 402, the function of the regulating device 4 is further refined, so that the opening of the diverter port 201 can be adjusted more accurately. Specifically, the design of the flow guide component 401 allows the concentrated slurry to be received by the carrier 4011 when flowing through the diverter port 201, and the gravity is transferred to the control component 402, and the control component 402 dynamically adjusts the opening of the adjacent diverter port 201 according to the gravity change, thereby ensuring the automatic balance of the flow.

[0110] The inlet end of the flow guide component 401 is located below the Nth diversion port 201, and the concentrated slurry flowing in is collected through the support platform 4011. When the slurry flows through the support platform 4011, its gravity is transmitted to the control component 402 located below. The support platform 4011 is not only used to collect and transmit the gravity of the slurry, but also ensures that the slurry can stably flow to the N-1th diversion port 201 through the flow guide component 401, so as to ensure that the control component 402 obtains stable gravity feedback.

[0111] After receiving the gravity transmission from the carrier 4011, the control component 402 can adjust the opening of the N-1th diversion port 201 according to the change of gravity. When the gravity of the slurry on the carrier 4011 increases, the control component 402 will correspondingly reduce the opening of the N-1th diversion port 201 to limit the excessive inflow of slurry.

[0112] On the contrary, when the gravity on the support platform 4011 decreases, the control component 402 will increase the opening of the N-1th diversion port 201 to compensate for the insufficient supply and realize dynamic flow regulation.

[0113] Through the coordinated action of the flow guide assembly 401 and the control assembly 402, this embodiment can automatically respond to changes in the slurry gravity and adjust the opening of the diversion port 201 in real time. This design enables the system to automatically adjust when the slurry flow fluctuates, thereby preventing uneven distribution of slurry between adjacent shaking table devices 3.

[0114] The combination of gravity transmission and opening adjustment means that the system does not need complex sensing and control equipment, and can achieve automatic adjustment only through mechanical structure, which improves the reliability of the system and the convenience of maintenance.

[0115] It should be noted that the whole process is divided into two processes. The first process is the process in which the slurry gradually increases in the diversion trough, and at this time, it is sequentially transported from the 1st to the Nth diversion ports 201 to each shaking table device 3. When all the slurry in the thickening tank enters the diversion trough, the slurry will gradually decrease as it is discharged, and at this time, it will be sequentially transported from the Nth to the 1st diversion ports 201 to each shaking table device 3.

[0116] The sixth embodiment of the present invention provides a thickener distribution system, and based on the previous embodiment, the flow guide assembly 401 includes:

[0117] The bearing cavity 4012 is located above the N-1th diversion port 201 and is connected to the outlet end of the flow guide component 401;

[0118] The carrying platform 4011 is slidably connected to the bottom surface of the carrying cavity 4012 and forms a movable sealed connection with the bottom surface;

[0119] A one-way valve is provided at a port of the bearing cavity 4012 facing the diverter groove 1 .

[0120] In this embodiment, by adding a structural design of a bearing cavity 4012 to the flow guide assembly 401, the bearing platform 4011 can slide in the bearing cavity 4012, thereby further enhancing the effect of regulating the slurry flow. Specifically, the bearing cavity 4012 is located above the N-1th diversion port 201 and is connected to the outlet end of the flow guide assembly 401, and the bearing platform 4011 is connected to the bottom surface of the bearing cavity 4012 in a slidable manner.

[0121] When the slurry flows into the bearing cavity 4012, the gravity of the slurry acts on the bearing platform 4011, causing the bearing platform 4011 to slide downward in the bearing cavity 4012 according to the gravity. As the position of the bearing platform 4011 changes, the control component 402 can adjust the opening of the N-1th diversion port 201 according to the gravity of the slurry.

[0122] Through the sliding adjustment of the support platform 4011, the gravity change of the slurry can be transmitted to the control component 402 in real time, so as to dynamically adjust the flow rate and ensure that each shaking table device 3 receives a reasonable supply of slurry.

[0123] The bearing platform 4011 and the bottom surface of the bearing cavity 4012 form a slidable sealing connection, which maintains a good sealing effect when the bearing platform 4011 moves, avoids slurry leakage, and ensures stable operation of the system.

[0124] The sealing design not only prevents flow loss caused by slurry leakage during flow control, but also improves the reliability of the system, which is suitable for continuous operation industrial needs.

[0125] This embodiment can achieve a more sensitive dynamic response through the combined design of the slidable bearing platform 4011 and the bearing cavity 4012. The bearing platform 4011 automatically slides in the cavity according to the gravity of the slurry, so that the opening of the diversion port 201 can be adjusted in real time according to the slurry load.

[0126] The sliding adjustment method of this structure further improves the precise control of the flow rate. Especially when the slurry flow rate fluctuates greatly, the system can quickly adjust the flow distribution through the displacement of the supporting platform 4011 to ensure the load balance of each shaking table device 3.

[0127] In a specific embodiment, the function of adding a one-way valve is to prevent the slurry from entering the guide assembly (the guide assembly is in the form of a guide channel) from the bearing cavity 4012, so that the slurry can only enter from the inlet end of the guide assembly and flow out from the outlet end.

[0128] In a specific embodiment, the support platform 4011 is slidably connected to the bottom surface of the support cavity 4012 and forms a movable sealed connection with the bottom surface. Specifically, the bottom surface of the support cavity 4012 is a flexible surface, and the support platform is slidably connected below the bottom surface and contacts the bottom surface. When the slurry enters the inside of the support platform 4011, the flexible bottom surface is deformed downward, thereby causing the support platform 4011 to slide downward, thereby pushing the control component 402 to adjust the opening of the diverter 101. The support platform 4011 can be slidably connected to the inside of the inner wall of the diverter 1 (the inner wall has a corresponding space, and the support platform 4011 is connected in the form of a slider slot).

[0129] The seventh embodiment of the present invention provides a thickener distribution system, and based on the previous embodiment, the control component 402 includes:

[0130] Elastic member 4021 and valve body 4022;

[0131] Wherein, one end of the valve body 4022 is connected to the bearing platform 4011;

[0132] The elastic member 4021 provides an elastic force on the valve body 4022;

[0133] Furthermore, the direction of the elastic force is opposite to the gravity direction of the concentrated slurry.

[0134] In this embodiment, by adding the design of elastic member 4021 and valve body 4022 to control assembly 402, the system can add elastic feedback mechanism in the process of regulating the slurry flow. Specifically, one end of valve body 4022 is connected to support platform 4011, and valve body 4022 is located in diversion port 101. When the gravity force exerted by slurry on support platform 4011 increases, elastic member 4021 generates elastic force in the opposite direction to balance or adjust the position of valve body 4022, thereby controlling the opening of diversion port 201.

[0135] The elastic member 4021 is connected to the valve body 4022 and always applies an elastic force in a direction opposite to the gravity of the slurry. When the gravity of the slurry on the support platform 4011 increases, the valve body 4022 moves downward, so that the opening of the diversion port 201 is appropriately reduced to limit the inflow of the slurry; when the gravity of the slurry decreases, the elastic member 4021 pushes the valve body 4022 upward to increase the opening of the diversion port 201 to compensate for the slurry flow.

[0136] The addition of the elastic member 4021 provides the system with a "buffer" mechanism. When the slurry flow rate fluctuates, the elastic force provided by the elastic member 4021 can help the system gradually adjust the flow rate instead of changing it immediately. This can reduce the impact of flow fluctuations on the system and ensure the stability of the distribution system.

[0137] The connection between the elastic member 4021 and the valve body 4022 enables the system to achieve gradual adjustment and automatic balance when encountering changes in the weight of the slurry, thereby reducing the wear on the equipment caused by frequent adjustments.

[0138] In this embodiment, the system realizes the ability of automatic response and dynamic balance adjustment through the combined design of the elastic member 4021 and the valve body 4022. Even when the slurry flow rate and concentration fluctuate greatly, the elastic force of the elastic member 4021 can automatically compensate and limit the opening of the diversion port 201, ensuring the relative uniformity of the flow rate and the stable operation of the equipment.

[0139] In one specific implementation, the elastic member 4021 is a spring.

[0140] In a specific embodiment, the wall surface of the diverter 1 is divided into an inner wall surface and an outer wall surface, and there is a certain gap between the inner wall surface and the outer wall surface. The diverter port 101 located on the outer wall surface and the diverter port 101 located on the inner wall surface are connected through a pipeline located in the gap to form the same diverter port 101. The valve body 4022 is slidably connected in the pipeline. A groove is provided on the top end surface of the pipeline, and the valve body 4022 is slidably inserted in the groove and is located in the pipeline. When the bearing platform 4011 senses gravity, the area of ​​the valve body 4022 entering the pipeline increases to reduce the opening of the diverter port 101. When the gravity decreases or disappears, the elastic member 4021 pushes the bearing platform 4011 upward, thereby driving the valve body 4022 to move upward, so that the opening of the diverter port 101 increases.

[0141] The eighth embodiment of the present invention provides a thickener distribution system, and based on the previous embodiment, comprises a compensation pipeline 5, wherein the compensation pipeline 5 is connected to the secondary thickener tank of the thickener 1;

[0142] The outlet end of the compensation pipeline 5 is connected to the Nth shaking table device 3 .

[0143] In this embodiment, the focus is on centralized treatment of the small amount of slurry remaining in the secondary thickener. Although the secondary thickener is mainly used to carry the clear liquid, it may still contain a small amount of slurry that has not been completely settled. Therefore, the function of the compensation pipeline 5 is to guide the slurry to the shaking table device 3, ensure the quality of the clear liquid in the secondary thickener, and effectively utilize the residual slurry resources.

[0144] In the thickener 1 system, the secondary thickener is mainly responsible for carrying the thickened clear liquid, but there are still a small amount of incompletely settled pulp particles in the clear liquid. As the clear liquid gradually accumulates, the pulp concentration in the secondary thickener will slowly increase. The design of the compensation pipeline 5 is to centrally transport this part of the pulp in the secondary thickener to the shaking table device 3 for processing, thereby avoiding the accumulation of pulp in the secondary thickener and ensuring the quality of the clear liquid.

[0145] Through the compensation pipeline 5, the system can transport the slurry in the secondary thickener to the shaking table device 3 for sorting, further improving the utilization efficiency of slurry resources. This design not only achieves the separation of clear liquid and slurry, but also maximizes the utilization of the slurry remaining in the secondary thickener to avoid waste.

[0146] In situations where strict requirements are placed on the discharge of the clear liquid, the role of the compensation pipeline 5 is particularly critical. It helps to reduce the impact of the slurry residue in the secondary thickener on the purity of the clear liquid, and ensures that the clear liquid of the thickener 1 system meets environmental protection and process standards.

[0147] The compensation pipeline 5 not only transports the slurry from the secondary thickener to the shaking table device 3, but also serves as a dynamic supplement mechanism. When the slurry flow rate of the main thickener is insufficient or unstable, the compensation pipeline 5 will guide the slurry from the secondary thickener to the Nth shaking table device 3 to maintain the continuity of slurry supply. This function is particularly applicable under conditions with large flow fluctuations. It can reduce the impact of uneven main diversion system through dynamic compensation and ensure stable supply of shaking table device 3.

[0148] The ninth embodiment of the present invention provides a thickener distribution system, and based on the previous embodiment, comprises a flow stabilizing device 6, which is arranged inside the flow divider 2;

[0149] Wherein, the flow stabilizing device 6 comprises a flow stabilizing tube with a conical structure;

[0150] The flow stabilizing tube is located at the center of the flow divider 2 , and the cone of the conical structure faces the discharge pipeline of the flow divider 2 .

[0151] In this embodiment, by arranging the flow stabilizing device 6 inside the diverter 2, the stability of the slurry flow is further improved, ensuring that the slurry is distributed more evenly in the diverter 2. Specifically, the flow stabilizing device 6 is a conical flow stabilizing cylinder, which is located at the center of the diverter 2, and its cone is arranged toward the discharge pipeline. The conical flow stabilizing cylinder can effectively guide the flow of the slurry, reduce turbulence and turbulence, and thus achieve uniform flow before the slurry enters each diverter port 201.

[0152] The flow stabilizer adopts a conical design, and the cone faces the discharge pipe of the diverter 2. When the slurry flows through the diverter 2, the flow stabilizer gradually guides the fluid to disperse along the conical surface through its unique conical structure, reducing the turbulence and turbulence of the fluid. The direction of the cone design makes the slurry gradually slow down in the process of flowing along the conical surface, ensuring a more stable flow direction. This guiding effect enables the slurry to be pre-rectified before entering each diversion port 201, thereby providing a uniform flow basis for subsequent slurry distribution and reducing the impact of flow fluctuations on each diversion port 201.

[0153] The flow stabilizer is located at the center of the diverter 2, so that the slurry is guided into a laminar or quasi-laminar state inside the diverter 2, avoiding local excessive flow or turbulence. By slowing down the slurry flow rate, the conical flow stabilizer can keep the fluid at a uniform pressure and velocity distribution when it reaches the diverter port 201, thereby improving the distribution accuracy. The conical structure can also reduce the impact force of the slurry on the inner wall of the diverter 2, thereby reducing wear and extending the service life of the diverter 2.

[0154] Through the conical design of the flow stabilizing device 6, this embodiment can effectively prevent the slurry from forming irregular turbulence or turbulence in the diverter 2, making the flow of the slurry more stable and uniform, and improving the distribution effect of the system.

[0155] In a specific embodiment, a guide groove 7 is included, which is arranged on the circumferential wall of the flow stabilizing cylinder and is arranged along its length direction. By arranging the guide groove 7 on the circumferential wall of the flow stabilizing cylinder, the guiding effect of the slurry flow is further optimized. The guide groove 7 is arranged along the length direction of the flow stabilizing cylinder, so that the slurry can obtain a clear flow path when flowing along the cone surface, thereby reducing turbulence and enhancing the flow stability of the slurry. The design of the guide groove 7 makes the slurry more uniform when flowing through the diverter 2, further improving the distribution effect of the system.

[0156] The guide groove 7 arranged on the circumferential wall of the flow stabilizing tube can guide the slurry to flow in a spiral or parallel laminar manner along the surface of the flow stabilizing tube. This flow path control reduces the turbulence and irregular velocity changes of the fluid, making the slurry more uniform and stable when flowing through the surface of the cone. The design of the guide groove 7 ensures that the slurry can gradually slow down during the flow process and maintain a stable flow rate and flow before entering each diversion port 201, effectively improving the fluid uniformity of the distribution system. The guide groove 7 forms a "channel effect" on the surface of the flow stabilizing tube, guiding the slurry to flow along the set path, avoiding turbulence caused by the disordered movement of the fluid. By reducing turbulence, the system can effectively maintain stability during the flow of the slurry, ensuring that the slurry has a consistent flow distribution when entering the diversion port 201. In the case of high flow velocity or large flow fluctuations, the guiding effect of the guide groove 7 is particularly obvious, which can significantly improve the control effect of the slurry flow.
