Abstract
Description
Technical Field
[0001] The present invention belongs to the technical field of slurry processing, relates to a technology for improving slurry diversion efficiency, and particularly relates to a thickener distribution system. Background Art
[0002] Thickeners are widely used in mineral processing, metallurgy, and chemical engineering, primarily for solid-liquid separation and concentration of ore slurries. Through sedimentation, thickeners effectively remove the supernatant from the slurry, concentrating the solid particles into a highly concentrated slurry for subsequent processing or discharge. Thickeners are typically designed as gravity settling devices, and when used with flocculants, they can improve particle settling efficiency and achieve rapid concentration.
[0003] In actual applications, the slurry concentrated in the thickener usually needs to be further processed through a shaking table device. In the existing technology, the thickener usually needs to be connected to multiple shaking tables. The positions of these shaking tables vary in distance depending on the actual production process layout. That is, some shaking tables are farther away 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 the transportation process may be uneven. Specifically,
[0004] The slurry flow rate of the slurry table devices at a short distance is relatively high: Due to the short pipes and low resistance, the slurry flows smoothly to the slurry table devices at a short distance, so these slurry table devices usually receive a large amount of slurry. The slurry flow rate of the slurry table devices at a long distance is relatively low: Due to the long pipes and high resistance, the slurry flow rate of the slurry table devices far away from the thickening tank will decrease or decrease before reaching these devices, resulting in a significantly insufficient amount of slurry received by these slurry table devices.
[0005] Due to insufficient slurry supply to distant shakers, these devices cannot operate at full capacity, resulting in reduced overall equipment utilization. Furthermore, nearby shakers, handling excessive slurry, may become overloaded, accelerating equipment wear and failure, and impacting production efficiency. Uneven slurry supply not only reduces shaker efficiency but also wastes energy and resources. Remote shakers may not operate at full capacity, resulting in wasted electricity and water resources, while nearby equipment may face increased maintenance and replacement requirements due to overload.

[0057] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[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 pipe 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 in one-to-one communication with a rocking device 3 , and the horizontal distance between the rocking device 3 and the diverter 2 is L;
[0064] The height H of each diversion port 201 is negatively correlated with the distance L to the corresponding shaking table device 3 it is connected to;
[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 a 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 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 shaker device 3 that is farthest from the diverter 2 (i.e., Lmax), the diverter port 201 is set at the lowest position (i.e., Hmin), ensuring that the shaker device 3 receives the slurry first. By increasing the liquid level pressure, the disadvantage of its greater distance is compensated, thereby ensuring the slurry flow rate to a certain extent.
[0069] For the shaking table device 3 closest to the diverter 2 (i.e., Lmin), the diverter port 201 is set at the highest point (i.e., 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 entire system as much as possible.
[0070] This height and distance design dynamically adjusts the slurry flow direction to a certain extent, optimizing the amount of slurry received by each shaking table unit 3. While it cannot completely guarantee that all shaking tables 3 receive exactly the same amount of slurry, this design can reduce flow rate variations and ensure more consistent slurry supply across each device. The system utilizes height differences to adjust the natural flow characteristics of the slurry, reducing flow rate unevenness caused by distance differences and optimizing supply balance.
[0071] This design can, to a certain extent, reduce the uneven slurry supply problem caused by the position differences of the shaking table devices 3 in the existing technology, and improve the overall separation efficiency of the system. Each shaking table device 3 receives a relatively balanced amount of slurry 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 structurally simple, relying primarily on height differences and gravity to distribute the slurry, avoiding complex mechanical or electrical controls. This physical design offers low maintenance, reducing maintenance requirements during system operation and lowering potential failure risks.
[0074] The thickener distribution system of this embodiment is not only suitable for distributing slurry across multiple shaker units 3 in the mineral processing industry, but can also be applied to other processes requiring 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 rationally designing the relationship between the height of the diversion port 201 and the distance from the shaking table device 3, alleviates, to a certain extent, the uneven slurry supply problem caused by distance differences in the prior art, thereby improving the efficiency and stability of the thickener distribution system. However, due to actual operating conditions and slurry characteristics, this system can only achieve relatively uniform distribution within a certain range.
[0076] In a specific embodiment, the diverter 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. 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 it is connected to. 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 its value range is 0.05 to 0.2.
[0080] In this embodiment, the diameter D of each diverter port 201 is further designed to be positively correlated with the horizontal distance L between its corresponding shaking device 3. This optimizes the slurry distribution between shaking devices 3 at different distances. Specifically, the diameter of the diverter port 201 increases as its distance from the shaking device 3 increases. This design, combined with the height adjustment mechanism of the diverter port 201 in the first embodiment, enhances the balance and flexibility of the slurry distribution system in multiple dimensions. According to the formula Di = Dmin + k * (Lmax - Li), shaking devices 3 farther away from the diverter 2 (i.e., with a larger Li), the diverter port 201 with a larger diameter Di also corresponds to a larger diameter Di.
[0081] This design increases the flow rate by increasing the opening area of the long-distance diversion port 201 to compensate for flow losses caused by long distances, thereby increasing the slurry supply. The closer the shaking table 3 (i.e., with a smaller Li), the smaller the diversion port 201 diameter is, to prevent excessive slurry inflow and maintain overall system balance. By adjusting the diversion port 201 diameter, flow control not only relies on liquid level difference and height, but also incorporates the diameter parameter to further fine-tune the flow rate. This way, even if there are uncertainties in the slurry flow (such as pipeline resistance and liquid level fluctuations), diameter adjustment can compensate to a certain extent, reducing the difference in slurry flow between the long-distance and short-distance shaking table 3.
[0082] The diameter adjustment coefficient k is set within a range of 0.05 to 0.2. This adjustment range ensures flexibility in adjusting the diameter of the diverter port 201 while preventing the negative impact of excessive or insufficient adjustment on the system. By incorporating both the height and diameter of the diverter port 201 into the adjustment range, this embodiment can more effectively reduce uneven slurry supply caused by differences in the distance between the shaking table devices 3, and to a certain extent improve the uniformity of slurry distribution between the shaking table devices 3. Even in the presence of fluctuations in slurry flow rate or concentration, this multi-parameter adjustment mechanism maintains high system adaptability and flexibility.
[0083] The third embodiment of the present invention provides a thickener distribution system. Based on the previous embodiment, the height H of the diversion port 201 and the distance L to the corresponding shaking table device 3 satisfy the following conditions:
[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, the balanced distribution of slurry is further optimized by introducing an adjustable relationship between the height H of diverter port 201 and the distance L from the corresponding shaking table 3. Specifically, the height of diverter port 201 is adjusted according to the formula Hi = Hmax - m * (Lmax - Li), so that the height of diverter port 201 decreases as the horizontal distance from the shaking table 3 increases. This design, based on the previous embodiment, achieves more precise control of slurry flow through height difference adjustment.
[0087] According to the formula, when the shaking table device 3 is far away from the diverter 2 (i.e., 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] Conversely, when the shaking table 3 is closer to the diverter 2 (i.e., Li is smaller), the diverter port 201 height Hi is higher, causing the slurry to flow preferentially to the more distant shaking table 3 and then to the nearby equipment. This design combines the diameter adjustment function of the previous embodiment to further improve flow balance.
[0089] This embodiment combines dual adjustment of diameter and height: diameter adjustment allows for differentiating the size of the diversion openings 201 of the distal and proximal shaker devices 3, while height adjustment optimizes flow distribution by utilizing liquid level differences. Through dual adjustment of height and diameter, the system achieves dynamic and balanced slurry distribution.
[0090] The height adjustment coefficient m ranges from 0.1 to 0.5, ensuring a moderate height change and a stable diversion effect. This range of adjustment coefficients can adapt to different flow rates and slurry concentrations.
[0091] This embodiment further refines the slurry distribution by adjusting the height, while ensuring the diameter of the diversion port 201 can be changed in the above embodiment. In this way, even when the pipe resistance and distance vary greatly, the system can still ensure that the slurry volume received by the near and far 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 slurry according to the distance of the shaking table device 3, and dynamic adjustment of slurry supply can be achieved without additional mechanical or electrical control devices.
[0094] By jointly adjusting the height and diameter, this embodiment further improves the balance of slurry distribution on the basis of the previous embodiment, reduces the uneven supply phenomenon caused by differences 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 provides a thickener distribution system, and based on the previous embodiment, includes:
[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 adjusts the opening of the N-1th diversion port 201 adjacent thereto when controlled by the gravity of the concentrated slurry as a force.
[0099] In this embodiment, by adding a 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, preventing uneven equipment load caused by excessive slurry entering, thereby affecting the separation effect.
[0100] By automatically controlling the opening of each diversion port 201 through the regulating device 4, the amount of slurry received by each shaking table device 3 can be adjusted according to the changes in the gravity of the slurry. This design can compensate for distance differences, changes in slurry concentration, or fluctuations in system flow, thereby achieving a certain degree of flow balance.
[0101] This embodiment combines the height and diameter adjustments of the previous embodiments, and implements multi-level flow control through a gravity-sensing adjustment device 4. The height difference, diameter difference, and dynamic opening adjustment work together to ensure stable and continuous slurry supply to each shaking table device 3, further reducing uneven distribution caused by flow rate differences.
[0102] The fifth embodiment of the present invention provides a thickener distribution system. 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 diversion port 201;
[0105] The outlet end of the flow guide component 401 is located at the upper end of the N-1th 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 supporting 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 supporting platform 4011 and is configured to adjust the opening of the N−1th diversion port 201 according to the change in gravity of the concentrated slurry.
[0109] In this embodiment, the combined structure of a flow guide assembly 401 and a control assembly 402 further refines the function of the regulating device 4, enabling more precise adjustment of the opening of the diverter port 201. Specifically, the design of the flow guide assembly 401 allows the concentrated slurry to be received by the support platform 4011 as it flows through the diverter port 201, transferring gravity to the control assembly 402. The control assembly 402 dynamically adjusts the opening of adjacent diverter ports 201 based on this gravity change, thereby ensuring automatic flow balance.
[0110] The inlet of the flow guide assembly 401 is located below the Nth diversion port 201. The concentrated slurry is collected by a support platform 4011. As the slurry flows through the support platform 4011, its gravity is transmitted to the control assembly 402 located below. The support platform 4011 not only collects and transmits the gravity of the slurry but also ensures that the slurry can flow stably through the flow guide assembly 401 to the N-1th diversion port 201, ensuring that the control assembly 402 receives stable gravity feedback.
[0111] After receiving the gravity transmission from the support platform 4011, the control component 402 can adjust the opening of the N-1th diversion port 201 according to the change in gravity. When the gravity of the slurry on the support platform 4011 increases, the control component 402 will correspondingly reduce the opening of the N-1th diversion port 201 to prevent excessive inflow of slurry.
[0112] On the contrary, when the gravity on the carrier 4011 decreases, the control component 402 increases 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 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 slurry distribution 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 and maintenance convenience of the system.
[0115] It should be noted that the entire process is divided into two stages. The first stage is the process in which the slurry gradually increases in the diverter 2. At this time, the slurry is sequentially transported from the first to the Nth diverter ports 201 to each shaking table device 3. After all the slurry in the thickening tank enters the diverter 2, the slurry gradually decreases as it is discharged. At this time, the slurry is sequentially transported from the Nth to the first diverter ports 201 to each shaking table device 3.
[0116] The sixth embodiment of the present invention provides a thickener distribution system. 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 diversion 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 the port of the bearing cavity 4012 facing the diverter 2 .
[0120] In this embodiment, by adding a supporting cavity 4012 to the flow guide assembly 401, the supporting platform 4011 is able to slide within the supporting cavity 4012, thereby further enhancing the slurry flow regulation effect. Specifically, the supporting cavity 4012 is located above the N-1th diversion port 201 and is connected to the outlet of the flow guide assembly 401, while the supporting platform 4011 is slidably connected to the bottom surface of the supporting cavity 4012.
[0121] As the slurry flows into the chamber 4012, the gravity of the slurry acts on the platform 4011, causing it to slide downward within the chamber 4012 based on the gravity. As the position of the platform 4011 changes, the control assembly 402 adjusts the opening of the (N−1)th diversion port 201 based on 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, thereby dynamically adjusting the flow rate to ensure that each shaking table device 3 receives a reasonable supply of slurry.
[0123] The supporting platform 4011 and the bottom surface of the supporting cavity 4012 form a slidable sealing connection, which maintains a good sealing effect when the supporting 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 the flow control process, but also improves the reliability of the system and is suitable for industrial needs of continuous operation.
[0125] This embodiment can achieve a more sensitive dynamic response through the combined design of the slidable support platform 4011 and the support cavity 4012. The support 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 one embodiment, the function of adding a one-way valve is to prevent the slurry from entering the diversion assembly (the diversion assembly is in the form of a diversion channel) from the bearing cavity 4012, so that the slurry can only enter from the inlet end of the diversion assembly and flow out from the outlet end.
[0128] In one 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 in contact with the bottom surface. When the slurry enters the interior of the support platform 4011, the flexible bottom surface deforms downward, causing the support platform 4011 to slide downward, thereby pushing the control component 402 to adjust the opening of the diverter port 101. The support platform 4011 is slidably connected to the interior of the inner wall of the diverter 2 (the inner wall has a corresponding space, and the support platform 4011 is connected via a slider slot).
[0129] The seventh embodiment of the present invention provides a thickener distribution system. Based on the previous embodiment, the control component 402 includes:
[0130] Elastic member 4021 and valve body 4022;
[0131] One end of the valve body 4022 is connected to the supporting platform 4011;
[0132] The elastic member 4021 provides an elastic force on the valve body 4022;
[0133] Moreover, the direction of the elastic force is opposite to the direction of gravity of the concentrated slurry.
[0134] In this embodiment, by adding an elastic member 4021 and a valve body 4022 to the control assembly 402, the system incorporates an elastic feedback mechanism during slurry flow regulation. Specifically, one end of the valve body 4022 is connected to the support platform 4011, and the valve body 4022 is located within the diversion port 101. As the gravitational force exerted by the slurry on the support platform 4011 increases, the elastic member 4021 generates an elastic force in the opposite direction to balance or adjust the position of the valve body 4022, thereby controlling the opening of the diversion port 201.
[0135] Elastic member 4021 is connected to valve body 4022 and constantly applies an elastic force in a direction opposite to the gravity of the slurry. When the gravity of the slurry on support platform 4011 increases, valve body 4022 moves downward, narrowing the opening of diverter port 201 and limiting the inflow of slurry. When the gravity of the slurry decreases, elastic member 4021 pushes valve body 4022 upward, increasing the opening of diverter port 201 to compensate for the slurry flow.
[0136] The addition of elastic element 4021 provides the system with a "buffer" mechanism. When slurry flow fluctuates, the elastic force provided by elastic element 4021 helps the system gradually adjust the flow rate rather than causing an immediate change. This reduces the impact of flow fluctuations on the system and ensures 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 slurry weight, thereby reducing wear on the equipment caused by frequent adjustments.
[0138] In this embodiment, the combined design of elastic member 4021 and valve body 4022 enables the system to achieve automatic response and dynamic balance adjustment. Even when slurry flow and concentration fluctuate significantly, the elastic force of elastic member 4021 automatically compensates for and limits the opening of diversion port 201, ensuring relatively uniform flow and stable operation of the equipment.
[0139] In one embodiment, 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 pipe located in the gap to form the same diverter port 101. The valve body 4022 is slidably connected in the pipe. A groove is provided on the top end surface of the pipe, and the valve body 4022 is slidably inserted into the groove and is located in the pipe. When the supporting platform 4011 senses gravity, the area of the valve body 4022 entering the pipe increases to reduce the opening of the diverter port 101. When the gravity decreases or disappears, the elastic member 4021 pushes the supporting 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, includes a compensation pipe 5, wherein the compensation pipe 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 rocking table device 3 .
[0143] In this embodiment, the focus is on centralized processing of the small amount of slurry remaining in the secondary thickener. Although the secondary thickener is primarily used to carry clear liquid, it may still contain a small amount of unsettled slurry. Therefore, the compensation line 5 is used to guide this slurry to the shaking table device 3, ensuring the quality of the clear liquid in the secondary thickener and effectively utilizing the remaining slurry resources.
[0144] In the thickener 1 system, the secondary thickener primarily carries the thickened clear liquid. However, a small amount of unsettled pulp particles may still be present in the clear liquid. As the clear liquid gradually accumulates, the pulp concentration in the secondary thickener slowly increases. The compensation line 5 is designed to centrally transport this portion of the pulp in the secondary thickener to the shaker unit 3 for processing, thereby preventing pulp accumulation in the secondary thickener and ensuring the quality of the clear liquid.
[0145] Through the compensation pipe 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, avoiding waste.
[0146] In situations where strict requirements are placed on the discharge of the clear liquid, the role of the compensation line 5 is particularly critical. It helps to reduce the impact of the pulp residue in the secondary thickener on the purity of the clear liquid, ensuring that the clear liquid of the thickener 1 system meets environmental and process standards.
[0147] The compensation line 5 not only delivers slurry from the secondary thickener to the shaker unit 3 but also serves as a dynamic replenishment mechanism. When the slurry flow in the primary thickener is insufficient or unstable, the compensation line 5 directs the slurry from the secondary thickener to the Nth shaker unit 3 to maintain continuous slurry supply. This function is particularly useful under conditions with large flow fluctuations. Through dynamic compensation, it can mitigate the impact of uneven primary diversion systems and ensure a stable supply to the shaker unit 3.
[0148] The ninth embodiment of the present invention provides a thickener distribution system, and based on the previous embodiment, includes a flow stabilizing device 6 disposed 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 diverter 2 , and the cone of the conical structure faces the discharge pipe of the diverter 2 .
[0151] In this embodiment, a flow stabilizer 6 is provided within the diverter 2 to further enhance the stability of the slurry flow and ensure more uniform distribution of the slurry within the diverter 2. Specifically, the flow stabilizer 6 is a conical flow stabilizer located at the center of the diverter 2, with its cone facing the discharge pipe. The conical flow stabilizer effectively guides the slurry flow, reducing turbulence and turbulence, thereby achieving uniform flow before the slurry enters the diverter ports 201.
[0152] The flow stabilizer features a conical design, with the cone facing the discharge pipe of diverter 2. As the slurry flows through diverter 2, the flow stabilizer, through its unique conical structure, gradually guides the fluid along the conical surface, reducing turbulence and turbulence. The orientation of the cone gradually decelerates the slurry as it flows along the conical surface, ensuring a more stable flow. This guiding effect pre-rectifies the slurry before it enters each diverter port 201, providing a uniform flow foundation for subsequent slurry distribution and reducing the impact of flow fluctuations on each diverter port 201.
[0153] The flow stabilizer, located at the center of diverter 2, guides the slurry into a laminar or near-laminar flow state within diverter 2, avoiding localized excessive flow or turbulence. By slowing the slurry flow, the conical flow stabilizer ensures a uniform pressure and velocity distribution upon reaching diverter port 201, thereby improving distribution accuracy. The conical structure also reduces the impact of the slurry on the inner wall of diverter 2, thereby reducing wear and extending the service life of 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 one embodiment, a guide groove 7 is provided on the circumferential wall of the flow stabilizing cylinder and along its length. The provision of the guide groove 7 on the circumferential wall of the flow stabilizing cylinder further optimizes the slurry flow guidance. The arrangement of the guide groove 7 along the length of the flow stabilizing cylinder ensures a clear flow path for the slurry as it flows along the conical surface, thereby reducing turbulence and enhancing slurry flow stability. The design of the guide groove 7 ensures a more uniform slurry flow through the diverter 2, further enhancing the system's distribution efficiency.
[0156] The guide groove 7 provided 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.
