Abstract
Description
TECHNICAL FIELD
[0001] The utility model belongs to the technical field of ore pulp processing, and relates to a technology for improving ore pulp distribution efficiency, in particular to a thickener. BACKGROUND
[0002] The thickener is a device widely used in the fields of mineral processing, metallurgy and chemical engineering, mainly used for solid-liquid separation and concentration treatment of ore pulp. Through the sedimentation of the thickener, the clear liquid in the ore pulp can be effectively removed, and the solid particles are concentrated into high-concentration ore pulp for subsequent treatment or discharge. The thickener is usually designed as a gravity settling device, which can improve the particle settling efficiency and realize rapid concentration when used with flocculants.
[0003] In actual application, the ore pulp concentrated by the thickener usually needs to be further treated by a shaking table device. In the prior art, the thickener usually needs to be connected to multiple shaking table devices, and the positions of these shaking table devices are different in distance according to the actual production process layout, that is, some shaking table devices are far away from the thickener, and some are close to it. In this case, due to factors such as gravity, pipe length and resistance difference, the amount of ore pulp entering each shaking table device during transportation may be uneven after the ore pulp flows out of the thickener. The specific performance is as follows:
[0004] The shaking table devices close to the thickener receive more ore pulp: because the pipe is short and the resistance is small, the ore pulp flows smoothly to the shaking table devices close to the thickener, so these shaking table devices usually receive more ore pulp. The shaking table devices far away from the thickener receive insufficient ore pulp: the shaking table devices far away from the thickener have longer pipes and greater resistance, so the flow rate of the ore pulp decreases or the flow volume decreases before reaching these devices, resulting in a significant shortage of ore pulp received by these shaking table devices.
[0005] Due to the insufficient supply of ore pulp to the shaking table devices far away from the thickener, these devices cannot operate at full capacity, resulting in a decrease in the overall utilization rate of the equipment. In addition, the shaking table devices close to the thickener may operate at an overload, which can accelerate the wear and tear of the equipment and increase the failure rate, affecting the production efficiency. Uneven supply of ore pulp not only reduces the working efficiency of the shaking table devices, but also wastes energy and resources. The shaking table devices far away from the thickener cannot operate at full capacity, resulting in waste of electricity and water resources, while the devices close to the thickener may require more maintenance and replacement due to overloading.

DETAILED DESCRIPTION
[0059] 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.
[0060] Please refer to Figures 1 to 6 The specific embodiments provided by the present application are as follows:
[0061] As Figures 1 to 3 shown, the first embodiment of the present application provides a thickener, which comprises:
[0062] The thickener 1 has a discharge pipeline;
[0063] A flow divider 2 has a feeding end and a discharging end;
[0064] The feeding end is in communication with the discharge pipeline of the thickener 1;
[0065] N flow dividing ports 201 are arranged on the discharging end, and the N flow dividing ports 201 are arranged in sequence along the height direction of the flow divider 2, and the heights H are sequentially increased;
[0066] Each flow dividing port 201 is in one-to-one correspondence with a shaking table device 3, and the horizontal distance between the shaking table device 3 and the flow divider 2 is L;
[0067] The height H of each flow dividing port 201 is negatively correlated with the distance L of the corresponding shaking table device 3;
[0068] The negative correlation means that the shaking table device 3 farthest from the flow divider 2 is in communication with the flow dividing port 201 arranged at the lowest height of the flow divider 2, and the shaking table device 3 closest to the flow divider 2 is in communication with the flow dividing port 201 arranged at the highest height of the flow divider 2.
[0069] In this embodiment, the uniformity of the distribution of the slurry among the different shaking table devices 3 is improved to some extent by designing a negative correlation between the height H of the distribution port 201 in the distributor 2 and the distance to the shaking table device 3.
[0070] Specifically, the height H of each distribution port 201 of the distributor 2 decreases as the horizontal distance L between it and the shaking table device 3 increases. This design aims to utilize the difference in liquid level and the effect of gravity to optimize the flow distribution of the slurry to each shaking table device 3.
[0071] For the shaking table device 3 farthest from the distributor 2 (i.e., Lmax), the distribution port 201 is arranged at the lowest position (i.e., Hmin), ensuring that this shaking table device 3 receives the slurry preferentially. The disadvantage of being far away is compensated by increasing the liquid level pressure, thereby ensuring the flow of slurry to some extent.
[0072] For the shaking table device 3 closest to the distributor 2 (i.e., Lmin), the distribution port 201 is arranged at the highest position (i.e., Hmax), causing the slurry to flow preferentially to the devices farther away before flowing to the devices closer, in order to balance the distribution of slurry throughout the system as much as possible.
[0073] This height and distance design can dynamically adjust the flow of slurry to some extent, optimizing the amount of slurry received by each shaking table device 3. Although it cannot completely ensure that all shaking table devices 3 receive exactly equal amounts of slurry, this design can reduce the flow difference and make the supply of slurry to each device more balanced. The system utilizes the height difference to adjust the natural flow characteristics of the slurry, reducing the flow imbalance caused by distance differences and optimizing the balance of the supply.
[0074] This design can to some extent reduce the uneven supply problem caused by the position difference of the shaking table devices 3 in the prior art, improving 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 and processing effect of the equipment.
[0075] Through the design and adjustment of the height of the distribution port 201, the system can maintain a certain flexibility and stability under different working conditions, minimizing the imbalance problems caused by distance differences.
[0076] The thickener of this embodiment is simple in structure and mainly relies on the principle of height difference and gravity to achieve the distribution of the slurry, avoiding complex mechanical or electrical control. This physical design has low maintenance, reducing the maintenance requirements during system operation and reducing the potential risk of failure.
[0077] The thickener of the embodiment is not only suitable for slurry distribution of multiple shaking table devices 3 in the mineral processing industry, but also can be applied to other processes requiring multi-point slurry distribution. By optimizing the height design of the flow divider 201, the system flow uniformity can be improved to a certain extent to meet the requirements of different equipment layouts.
[0078] Therefore, the embodiment reasonably designs the relationship between the height of the flow divider 201 and the distance from the shaking table device 3, which to a certain extent alleviates the problem of uneven slurry supply caused by distance difference in the prior art, and improves the efficiency and stability of the thickener. However, due to the actual working conditions and the characteristics of the slurry, the system ensures a relatively uniform distribution effect within a certain range.
[0079] In a specific embodiment, the flow divider 2 is a cylindrical barrel or a rectangular groove for receiving the thickened slurry from the thickener 1.
[0080] On the basis of the above, it is further found that the poor flowability of the slurry may cause local accumulation in the flow divider, which may affect the slurry entering the flow divider 101, and therefore an adjusting device (not shown in the figure) is added, which is driven by a driving motor to rotate the adjusting disc, thereby forming stirring at the bottom of the slurry to increase the flowability of the slurry.
[0081] The adjusting disc is a disc structure in the form of a circular ring, and the driving motor is installed on the outer surface of the flow divider 1 and connected with the adjusting disc to drive the adjusting disc to rotate.
[0082] The second embodiment of the utility model provides a thickener, and on the basis of the first embodiment, the diameter D of each flow divider 201 and the horizontal distance L of the corresponding shaking table device 3 are in a positive correlation, wherein the diameter of the flow divider 201 is adjusted according to the following formula:
[0083] Di=Dmin+k*(Lmax−Li);
[0084] Wherein, Di represents the diameter of the i-th flow divider 201, Dmin is the minimum diameter, Lmax is the maximum horizontal distance between the shaking table device 3 and the flow divider 2, Li is the horizontal distance between the i-th shaking table device 3 and the flow divider 2; k is the diameter adjustment coefficient, and the value range is 0.05 to 0.2.
[0085] In the embodiment, by further designing the diameter D of each shunt 201 to be positively correlated with the horizontal distance L of the corresponding shaker device 3, the distribution effect of the ore pulp between shaker devices 3 at different distances is optimized. Specifically, the diameter of the shunt 201 increases as the distance between the shunt 201 and the shaker device 3 increases. This design combines the height adjustment mechanism of the shunt 201 in the first embodiment, improving the balance and flexibility of the ore pulp distribution system from multiple dimensions. According to the formula Di=Dmin+k*(Lmax−Li), the diameter Di of the shunt 201 corresponding to the shaker device 3 far away from the shunt 2 (i.e. Li is larger) is also larger.
[0086] This design compensates for the flow loss caused by the distance by increasing the opening area of the far distance shunt 201, thereby increasing the supply of ore pulp. The shaker device 3 at a short distance (i.e. Li is smaller) corresponds to a smaller shunt 201 diameter to prevent excessive flow of ore pulp and maintain the overall balance of the system. By adjusting the diameter of the shunt 201, not only the height and the liquid level difference are used to control the flow, but also the diameter is added to further fine-tune the flow. Even if there is some uncertainty in the ore pulp flow process (such as pipe resistance and liquid level fluctuation), the diameter adjustment can compensate to some extent, reducing the flow difference between the shaker devices 3 at different distances.
[0087] wherein the diameter adjustment coefficient k is set to be in the range of 0.05 to 0.2, such an adjustment range not only ensures the flexibility of the diameter change of the shunt 201, but also prevents the negative impact of excessive or insufficient adjustment on the system. By including the height and diameter of the shunt 201 in the adjustment range, the embodiment can more effectively reduce the uneven supply of ore pulp caused by the distance difference of the shaker devices 3, and to some extent, improve the uniformity of the distribution of ore pulp between the shaker devices 3. Even in the case of fluctuation of ore pulp flow rate or concentration, this multi-parameter adjustment mechanism can still maintain high system adaptability and flexibility.
[0088] The third embodiment of the utility model provides a thickener, and on the basis of the previous embodiment, the height H of the shunt 201 and the distance L of the corresponding shaker device 3 satisfy:
[0089] Hi=Hmax-m*(Lmax−Li);
[0090] wherein Hi represents the height of the i-th shunt 201, Hmax is the maximum height of the shunt 201, i.e. the height of the shunt 201 corresponding to the shaker closest to the shunt 2, Lmax is the maximum horizontal distance between the shaker device 3 and the shunt 2, Li is the horizontal distance between the i-th shaker device 3 and the shunt 2, m is the height adjustment coefficient, and the value range is 0.1 to 0.5.
[0091] In this embodiment, by introducing the adjustment relationship between the height H of the shunt port 201 and the distance L of the corresponding shaker device 3, the distribution uniformity of the ore pulp is further optimized. Specifically, the height of the shunt port 201 is adjusted according to the formula Hi = Hmax - m * (Lmax - Li), so that the height of the shunt port 201 decreases with the increase of the horizontal distance of the shaker device 3. This design realizes more accurate control of the ore pulp flow based on the previous embodiment through height difference adjustment.
[0092] According to the formula, when the shaker device 3 is far away from the shunt 2 (i.e. Li is large), the height Hi of the shunt port 201 is low, so as to increase the flow compensation by using the liquid level difference, and ensure that the far distance shaker device 3 can receive enough ore pulp.
[0093] On the contrary, when the shaker device 3 is close to the shunt 2 (i.e. Li is small), the height Hi of the shunt port 201 is high, so that the ore pulp flows to the far shaker device 3 first, and then to the near device. This design combines the function of diameter adjustment in the previous embodiment, further improving the uniformity of flow.
[0094] This embodiment combines the dual adjustment of diameter and height: diameter adjustment makes the size of the shunt port 201 of the far and near shaker devices 3 different, and height adjustment optimizes the flow distribution by using the liquid level difference. Through the dual adjustment of height and diameter, the system realizes the dynamic balanced distribution of ore pulp.
[0095] The value range of the height adjustment coefficient m is 0.1 to 0.5, which ensures that the height change is moderate, so that the shunting effect is stable. The adjustment coefficient in this range can adapt to the working condition requirements of different flow rates and ore pulp concentrations.
[0096] This embodiment further refines the ore pulp distribution by height adjustment based on the diameter change of the shunt port 201 in the previous embodiment. In this way, even in the case of large differences in pipeline resistance and distance, the system can still ensure that the ore pulp received by the far and near shaker devices 3 is relatively uniform.
[0097] Using height difference to compensate flow makes the ore pulp can be automatically distributed according to the position of each shaker device 3, further enhancing the stability of the system and the uniformity of ore pulp distribution.
[0098] The dual adjustment of height and diameter enables the system to automatically realize the balanced distribution of ore pulp according to the distance of the shaker device 3, without the need for additional mechanical or electrical control devices to realize dynamic adjustment of ore pulp supply.
[0099] By jointly adjusting the height and the diameter, the embodiment further improves the uniformity of the ore pulp distribution on the basis of the previous embodiment, reduces the uneven supply phenomenon caused by the distance and the pipeline resistance difference, and improves the separation efficiency of the shaking table device 3.
[0100] As shown in Figures 4 to 6 The fourth embodiment of the utility model provides a thickener, and on the basis of the previous embodiment, comprises:
[0101] The adjusting device 4 is arranged below each of the flow distribution ports 201.
[0102] The adjusting device 4 arranged below the Nth flow distribution port 201 automatically controls the opening degree of the adjacent (N-1)th flow distribution port 201 when subjected to the gravity of the thickened ore pulp as a force.
[0103] In the embodiment, by increasing the adjusting device 4, each flow distribution port 201 can be dynamically adjusted according to the actual ore pulp flow demand, thereby further improving the uniformity of the ore pulp distribution. Specifically, the adjusting device 4 is installed below each flow distribution port 201, and when the liquid level of the thickened ore pulp reaches a certain flow distribution port 201 (the Nth flow distribution port 201) and is subjected to the gravity of the thickened ore pulp, the adjusting device 4 automatically controls the opening degree of the adjacent flow distribution port 201 (the N-1)th flow distribution port 201), so as to prevent excessive ore pulp from flowing into the adjacent N-1 shaking table devices 3. The design ensures the reasonable distribution of the ore pulp to a certain extent, prevents uneven load of the equipment caused by excessive ore pulp, and further affects the separation effect
[0104] By automatically controlling the opening degree of each flow distribution port 201 through the adjusting device 4, the amount of ore pulp received by each shaking table device 3 can be adjusted according to the change of the gravity of the ore pulp. The design can compensate for the distance difference, the change of the ore pulp concentration or the system flow fluctuation, thereby achieving flow balance to a certain extent.
[0105] The embodiment combines the height adjustment and the diameter adjustment in the previous embodiments, and further realizes multi-level flow control through the gravity-sensitive adjusting device 4. The height difference, the diameter difference and the dynamic opening degree adjustment cooperate with each other to ensure that the ore pulp can be stably and continuously supplied to each shaking table device 3, thereby further reducing the uneven distribution problem caused by the flow difference.
[0106] The fifth embodiment of the utility model provides a thickener, and on the basis of the previous embodiment, the adjusting device 4 comprises:
[0107] The adjusting device 4 comprises a flow guide assembly 401 and a control assembly 402.
[0108] The adjusting device 4 comprises a flow guide assembly 401 and a control assembly 402.
[0109] The inlet end of the flow guide assembly 401 is located below the Nth shunt port 201.
[0110] The outlet end of the flow guide assembly 401 is located at the upper end of the N-1th shunt port 201.
[0111] The control assembly 402 is located below the outlet end of the flow guide assembly 401.
[0112] The flow guide assembly 401 has a bearing table 4011 for bearing the concentrated ore slurry and transmitting its gravity to the control assembly 402.
[0113] The control assembly 402 is connected with the bearing table 4011 and is configured to adjust the opening degree of the N-1th shunt port 201 according to the change of the gravity of the concentrated ore slurry.
[0114] In this embodiment, by introducing the combined structure of the flow guide assembly 401 and the control assembly 402, the function of the adjusting device 4 is further refined, and the adjustment of the opening degree of the shunt port 201 is more accurate. Specifically, the design of the flow guide assembly 401 allows the concentrated ore slurry to be received by the bearing table 4011 when flowing through the shunt port 201, and the gravity is transmitted to the control assembly 402, and the control assembly 402 dynamically adjusts the opening degree of the adjacent shunt port 201 according to the change of the gravity, thereby ensuring the automatic balance of the flow.
[0115] The inlet end of the flow guide assembly 401 is located below the Nth shunt port 201, and the concentrated ore slurry flowing in is collected by the bearing table 4011. When the ore slurry flows through the bearing table 4011, its gravity is transmitted to the control assembly 402 located below. The bearing table 4011 not only collects and transmits the gravity of the ore slurry, but also ensures that the ore slurry can stably flow through the flow guide assembly 401 to the N-1th shunt port 201, so as to ensure that the control assembly 402 obtains stable gravity feedback.
[0116] After receiving the gravity transmission from the bearing table 4011, the control assembly 402 can adjust the opening degree of the N-1th shunt port 201 according to the change of the gravity. When the gravity of the ore slurry on the bearing table 4011 increases, the control assembly 402 will correspondingly reduce the opening degree of the N-1th shunt port 201 to limit the excessive inflow of ore slurry.
[0117] Conversely, when the gravity on the bearing table 4011 decreases, the control assembly 402 will increase the opening degree of the N-1th shunt port 201, so as to compensate for the insufficient supply and realize dynamic flow adjustment.
[0118] Through the cooperation of the flow guide assembly 401 and the control assembly 402, the embodiment can automatically respond to the change of the gravity of the ore pulp and adjust the opening degree of the flow distribution port 201 in real time. This design enables the system to automatically adjust when the ore pulp flow fluctuates, thereby preventing uneven distribution of the ore pulp between adjacent shaking table devices 3.
[0119] The combination of gravity transmission and opening degree adjustment enables the system to automatically adjust through a mechanical structure without complex sensing and control equipment, thereby improving the reliability and maintenance convenience of the system.
[0120] It should be noted that the whole process is divided into two processes, the first process is that the ore pulp gradually increases in the flow distributor 2, at this time the first to the Nth flow distribution ports 201 are sequentially transported to the shaking table devices 3. When the ore pulp in the thickening tank is completely discharged into the flow distributor 2, the ore pulp gradually decreases with the discharge of the ore pulp, at this time the Nth to the first flow distribution ports 201 are sequentially transported to the shaking table devices 3.
[0121] The sixth embodiment of the utility model provides a thickener, and on the basis of the previous embodiment, the flow guide assembly 401 comprises:
[0122] The bearing cavity 4012 is located above the N-1th flow distribution port 201 and is in communication with the outlet end of the flow guide assembly 401;
[0123] The bearing platform 4011 is slidably connected to the bottom surface of the bearing cavity 4012 and forms a movable sealing connection with the bottom surface;
[0124] The one-way valve is arranged at the port of the bearing cavity 4012 facing the flow distributor 2.
[0125] In the embodiment, the bearing platform 4011 can slide in the bearing cavity 4012 by increasing the structure design of the bearing cavity 4012 in the flow guide assembly 401, thereby further enhancing the adjustment effect of the ore pulp flow. Specifically, the bearing cavity 4012 is located above the N-1th flow distribution port 201 and is in communication with the outlet end of the flow guide assembly 401, and the bearing platform 4011 is slidably connected to the bottom surface of the bearing cavity 4012.
[0126] When the ore pulp flows into the bearing cavity 4012, the gravity of the ore pulp acts on the bearing platform 4011, so that the bearing platform 4011 slides downward in the bearing cavity 4012 according to the gravity. With the change of the position of the bearing platform 4011, the control assembly 402 can adjust the opening degree of the N-1th flow distribution port 201 according to the gravity of the ore pulp.
[0127] Through the sliding adjustment of the bearing table 4011, the gravity change of the ore pulp can be transmitted to the control assembly 402 in real time, so as to dynamically adjust the flow and ensure that each shaking table device 3 receives reasonable ore pulp supply.
[0128] The bearing table 4011 and the bottom surface of the bearing cavity 4012 form a slidable sealing connection, which maintains good sealing effect when the bearing table 4011 moves, avoids ore pulp leakage, and ensures stable operation of the system.
[0129] The sealing design not only prevents flow loss caused by ore pulp leakage during flow control, but also improves the reliability of the system, which is suitable for continuous operation of industrial needs.
[0130] Through the combination design of the slidable bearing table 4011 and the bearing cavity 4012, the embodiment can realize more sensitive dynamic response. The bearing table 4011 automatically slides in the cavity according to the gravity of the ore pulp, so that the opening degree of the flow divider 201 can be adjusted in real time according to the ore pulp load.
[0131] The sliding adjustment mode of the structure further improves the precise control of the flow, especially in the case of large fluctuation of the ore pulp flow, the system can quickly adjust the flow distribution through the displacement of the bearing table 4011, and guarantee the load balance of each shaking table device 3.
[0132] In a specific embodiment, the function of the one-way valve is to prevent ore pulp from entering the flow guide assembly (the flow guide assembly is in the form of a flow guide channel) from the bearing cavity 4012. So that the ore pulp can only enter from the inlet end of the flow guide assembly and flow out from the outlet end.
[0133] In a specific embodiment, the bearing table 4011 is slidably connected to the bottom surface of the bearing cavity 4012 and forms a movable sealing connection with the bottom surface. Specifically, the bottom surface of the bearing cavity 4012 is a flexible surface, and the bearing table is slidably connected below the bottom surface and in contact with the bottom surface. When the ore pulp enters the inside of the bearing table 4011, the flexible bottom surface deforms downward, which in turn causes the bearing table 4011 to slide downward, thereby pushing the control assembly 402 to adjust the opening degree of the flow divider 101. The bearing table 4011 is slidably connected inside the inner wall of the flow divider 1 (the inner wall has a corresponding space, and the bearing table 4011 is connected by the form of sliding block and sliding groove).
[0134] The seventh embodiment of the utility model provides a thickener, and on the basis of the previous embodiment, the control assembly 402 comprises:
[0135] The elastic member 4021 and the valve body 4022;
[0136] Wherein, one end of the valve body 4022 is connected with the bearing table 4011;
[0137] The elastic member 4021 provides an elastic force to the valve body 4022;
[0138] Moreover, the direction of the elastic force is opposite to the direction of the gravity of the concentrated slurry.
[0139] In this embodiment, the elastic member 4021 and the valve body 4022 are added in the control assembly 402, so that the system can add an elastic feedback mechanism during the adjustment of the slurry flow. Specifically, one end of the valve body 4022 is connected to the bearing table 4011, and the valve body 4022 is located in the flow distribution port 201. When the gravity of the slurry applied to the bearing table 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 degree of the flow distribution port 201.
[0140] The elastic member 4021 is connected to the valve body 4022 and always applies an elastic force in the direction opposite to the gravity of the slurry. When the gravity of the slurry on the bearing table 4011 increases, the valve body 4022 moves downward, so that the opening degree of the flow distribution port 201 is appropriately reduced to limit the inflow amount of the slurry; when the gravity of the slurry decreases, the elastic member 4021 pushes the valve body 4022 upward to increase the opening degree of the flow distribution port 201 to compensate for the slurry flow.
[0141] The addition of the elastic member 4021 enables the system to have a “cushioning” mechanism. When the slurry flow fluctuates, the elastic force provided by the elastic member 4021 can help the system to gradually adjust the flow instead of changing immediately. In this way, the impact of flow fluctuation on the system can be reduced, and the stability of the distribution system can be ensured.
[0142] The connection of the elastic member 4021 and the valve body 4022 enables the system to gradually adjust and automatically balance when the weight of the slurry changes, thereby reducing the wear and tear of the equipment caused by frequent adjustment.
[0143] In this embodiment, the combination of the elastic member 4021 and the valve body 4022 enables the system to have the ability of automatic response and dynamic balance adjustment. Even in the case of large fluctuations in the slurry flow and concentration, the elastic force of the elastic member 4021 can automatically compensate and limit the opening degree of the flow distribution port 201, ensuring the relative uniformity of the flow and the stable operation of the equipment.
[0144] In a specific embodiment, the elastic member 4021 is a spring.
[0145] In a specific embodiment, the wall surface of the flow divider 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 flow dividing port 101 located on the outer wall surface and the flow dividing port 101 located on the inner wall surface are communicated through a pipeline located in the gap to constitute the same flow dividing port 101. The valve body 4022 is slidingly connected in the pipeline. The top end surface of the pipeline is provided with a groove, and the valve body 4022 is slidingly inserted into the groove and located in the pipeline. When the bearing table 4011 senses gravity, the area of the valve body 4022 entering the pipeline increases, thereby reducing the opening degree of the flow dividing port 101. When the gravity decreases or disappears, the elastic member 4021 pushes the bearing table 4011 upwards, thereby driving the valve body 4022 to move upwards, so that the opening degree of the flow dividing port 101 increases.
[0146] The eighth embodiment of the utility model discloses a thickener, and based on the previous embodiment, comprising compensation pipeline 5, compensation pipeline 5 is connected in secondary thickening tank of thickener 1;
[0147] The outlet end of the compensation pipeline 5 is communicated with the Nth shaking table device 3.
[0148] In this embodiment, the focus is on the concentrated treatment of the small amount of ore pulp remaining in the secondary thickening tank. Although the secondary thickening tank is mainly used for carrying the clear liquid, it still contains a small amount of ore pulp that has not completely settled. Therefore, the function of the compensation pipeline 5 is to guide these ore pulps to the shaking table device 3, to ensure the quality of the clear liquid in the secondary thickening tank, and to effectively utilize the residual ore pulp resources.
[0149] In the thickener 1 system, the secondary thickening tank mainly undertakes the function of carrying the clear liquid after thickening, but there will still be a small amount of ore pulp particles in the clear liquid that have not completely settled. As the clear liquid accumulates gradually, the concentration of the ore pulp in the secondary thickening tank will slowly increase. The design of the compensation pipeline 5 aims to concentrate the delivery of this part of the ore pulp in the secondary thickening tank to the shaking table device 3 for processing, thereby avoiding the accumulation of ore pulp in the secondary thickening tank and ensuring the quality of the clear liquid.
[0150] Through the compensation pipeline 5, the system can deliver the ore pulp in the secondary thickening tank to the shaking table device 3 for separation, further improving the utilization efficiency of the ore pulp resources. This design not only realizes the separation of the clear liquid and the ore pulp, but also maximizes the utilization of the residual ore pulp in the secondary thickening tank, avoiding waste.
[0151] In the case of strict clear liquid discharge requirements, the role of the compensation pipeline 5 is particularly critical, as it helps to reduce the impact of residual ore pulp in the secondary thickening tank on the purity of the clear liquid, ensuring that the clear liquid of the thickener 1 system meets environmental and process standards.
[0152] The compensation pipeline 5 not only transports the slurry of the secondary thickening tank to the shaking table device 3, but also can be used as a dynamic compensation mechanism. When the slurry flow of the main thickening tank is insufficient or unstable, the compensation pipeline 5 guides the slurry flow of the secondary thickening tank to the Nth shaking table device 3, so as to maintain the continuity of slurry supply. This function is particularly suitable for the working condition with large flow fluctuation, and can reduce the influence of unevenness of the main shunting system through dynamic compensation, so as to ensure the stable supply of the shaking table device 3.
[0153] The ninth embodiment of the utility model discloses a thickener, and on the basis of the previous embodiment, a flow stabilizing device 6 is arranged in the interior of the shunt 2.
[0154] The flow stabilizing device 6 comprises a flow stabilizing cylinder in a conical structure.
[0155] The flow stabilizing cylinder is located at the center of the shunt 2, and the cone body of the conical structure faces the discharge pipeline of the shunt 2.
[0156] In this embodiment, the flow stabilizing device 6 is arranged in the interior of the shunt 2, which further improves the stability of the slurry flow and ensures that the distribution of the slurry in the shunt 2 is more uniform. Specifically, the flow stabilizing device 6 is a flow stabilizing cylinder in a conical structure, which is located at the center of the shunt 2, and the cone body faces the discharge pipeline. The conical flow stabilizing cylinder can effectively guide the slurry flow, reduce turbulence and turbulence, and thus realize the uniformization of the flow before the slurry enters each shunt port 201.
[0157] The flow stabilizing cylinder adopts a conical design, and the cone body faces the discharge pipeline of the shunt 2. When the slurry flows through the shunt 2, the flow stabilizing cylinder gradually guides the fluid to disperse along the conical surface through its unique conical structure, reducing the turbulence and turbulence of the fluid. The design of the cone body makes the slurry gradually slow down during the flow along the conical surface, ensuring that the flow is more stable. This guiding effect makes the slurry realize pre-straightening before entering each shunt port 201, thereby providing a uniform flow basis for subsequent slurry distribution and reducing the influence of flow fluctuation on each shunt port 201.
[0158] The flow stabilizing cylinder is located at the center of the shunt 2, so that the slurry is guided to be in a laminar flow or an approximate laminar flow state in the interior of the shunt 2, avoiding local high flow rate or turbulence. By slowing down the slurry flow rate, the conical flow stabilizing cylinder can make the fluid maintain uniform pressure and velocity distribution when reaching the shunt 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 shunt 2, thereby reducing wear and tear and prolonging the service life of the shunt 2.
[0159] Through the conical design of the flow stabilizing device 6, this embodiment can effectively avoid the formation of irregular turbulence or turbulence of the slurry in the shunt 2, make the slurry flow more stable and uniform, and improve the distribution effect of the system.
[0160] Wherein, the flow stabilizing device 6 needs to avoid the rectifier device, since the rectifier disc is in a ring structure, the flow stabilizing device 6 is arranged in the inner ring of the ring structure, so as to avoid interference between the two.
[0161] In a specific embodiment, the flow guide groove 7 is arranged on the circumferential wall of the flow stabilizing cylinder and arranged along the length direction of the flow stabilizing cylinder. By arranging the flow guide groove 7 on the circumferential wall of the flow stabilizing cylinder, the guiding effect of the pulp flow is further optimized. The flow guide groove 7 is arranged along the length direction of the flow stabilizing cylinder, which can make the pulp obtain a clear flow path when flowing along the conical surface, thereby reducing turbulence and strengthening the flow stability of the pulp. The design of the flow guide groove 7 makes the pulp more uniform during flowing through the flow distributor 2, further improving the distribution effect of the system.
[0162] The flow guide groove 7 arranged on the circumferential wall of the flow stabilizing cylinder can guide the pulp to flow in a spiral or parallel laminar flow manner along the surface of the flow stabilizing cylinder. This flow path control reduces turbulence and irregular velocity changes of the fluid, making the pulp more uniform and stable when flowing through the surface of the cone. The design of the flow guide groove 7 ensures that the pulp can gradually slow down during the flow process and maintain a stable flow rate and flow before entering each flow distribution port 201, effectively improving the fluid uniformity of the distribution system. The flow guide groove 7 forms a "channel effect" on the surface of the flow stabilizing cylinder, guiding the pulp to flow along the set path and avoiding turbulence caused by disordered fluid motion. By reducing turbulence, the system can effectively maintain stability during the flow of the pulp, ensuring that the pulp has a consistent flow distribution when entering the flow distribution port 201. In the case of high flow rate or large flow fluctuation, the guiding effect of the flow guide groove 7 is particularly obvious, which can significantly improve the control effect of the pulp flow.
