Description

Technical Field

[0001] This application relates to the field of slurry processing technology, and in particular to a non-powered slurry distributor. Background Technology

[0002] Slurry distributors are essential equipment widely used in mineral processing, laboratory, and industrial applications. Their functions and structures are continuously optimized to meet diverse processes and needs. Taking mineral processing as an example, mineral processing involves crushing and grinding the ore based on its physical and chemical properties. Then, methods such as gravity separation, flotation, magnetic separation, and electrostatic separation are used to separate valuable minerals from gangue minerals, and to separate various associated (symbiotic) valuable minerals as much as possible, removing or reducing harmful impurities to obtain raw materials needed for smelting or other industries. In the aforementioned mineral processing, slurry distributors can buffer, separate, and evenly distribute the slurry, thereby uniformly distributing it to different processing units and reducing wear on the corresponding equipment.

[0003] However, existing slurry distributors typically use a combination of flow meters and valves to distribute slurry. Precise adjustment of the slurry distribution volume using flow meters and valves usually requires manual or electronic control to open and adjust the valves, making the process of uniform slurry distribution cumbersome and energy-intensive. Therefore, this application proposes a non-powered slurry distributor. Utility Model Content

[0004] This application provides a non-powered slurry distributor to solve the technical problems described in the background section.

[0005] To solve the above-mentioned technical problems, this application adopts the following technical solution: This application provides a non-powered slurry distributor, comprising: A columnar distribution housing, wherein a support shaft is provided in the middle of the bottom surface of the distribution housing and a feeding pipe is connected thereto, and a distribution disc with a diameter smaller than the inner diameter of the distribution housing is rotatably connected to the top of the support shaft. Multiple first distribution spaces are arranged at equal intervals around the center of the distribution disk on the upper surface of the distribution disk, and each of the first distribution spaces is connected to the bottom of the distribution cylinder located above the center of the distribution disk. The bottom end of the feeding pipe extends into the distribution cylinder. Multiple second distribution spaces are arranged at equal intervals around the support shaft and are all located below the distribution plate. Each second distribution space has a discharge port at its bottom for discharging the slurry that has entered from each of the first distribution spaces.

[0006] Optionally, a plurality of first distribution plates are equally spaced around the middle of the upper surface of the distribution plate, and each first distribution plate is located at a first preset distance from the center of the distribution plate on the side away from the outer peripheral wall of the distribution plate. The bottom surface of the distribution cylinder is connected to the top surface of the plurality of first distribution plates. The sidewalls of each pair of adjacent first distribution plates, together with the upper surface of the distribution disk, form a first distribution space.

[0007] Optionally, all of the first distribution plates are arc-shaped.

[0008] Optionally, the slurry flowing from the bottom of the distribution cylinder to each of the first distribution spaces faces the inner wall of one of the first distribution plates of the corresponding first distribution space.

[0009] Optionally, the first preset distance is 1 / 4 to 1 / 3 of the radius of the distribution disk.

[0010] Optionally, the inner bottom surface of the distribution housing is provided with a plurality of second distribution plates at equal intervals around the support shaft, and the top of each second distribution plate is a second preset distance from the lower surface of the distribution disk; The sidewalls of each pair of adjacent second distribution plates, together with the inner bottom surface and inner wall of the distribution housing and the outer wall of the support shaft, form a second distribution space.

[0011] Optionally, the second preset distance is 10cm to 25cm.

[0012] Optionally, the lower surface of the distribution disc is provided with a connecting shaft, and the bottom end of the connecting shaft is rotatably connected to the top end of the support shaft through a bearing.

[0013] Optionally, each of the discharge ports is connected to a slurry pipe, and the end of the slurry pipe away from the discharge port is used to connect to a slurry utilization device; The slurry pipe is equipped with a first slurry pump.

[0014] Optionally, one end of the feed pipe away from the distribution shell is used to connect to a slurry production device; A second slurry pump is installed on the feed pipe.

[0015] The non-powered slurry distributor provided in this application introduces slurry into a feed pipe, which then enters a distribution cylinder. As the slurry flows from the top to the bottom of the distribution cylinder, the weight of the slurry and the impact force of the slurry on the distribution disc generate kinetic energy, driving the distribution disc, which is rotatably connected to a support shaft, to rotate. Multiple first distribution spaces rotate synchronously with the distribution disc, causing the slurry flowing out of these spaces to generate centrifugal force. Under the action of this centrifugal force, the distribution disc is further pushed, thus achieving primary distribution of the slurry through the multiple first distribution spaces. Furthermore, as the first distribution spaces rotate with the distribution disc, the slurry flowing out of each first distribution space evenly enters multiple second distribution spaces. The slurry entering the second distribution spaces is discharged through the outlets above them, thus achieving secondary distribution of the slurry. Compared to existing slurry distributors that use a combination of flow meters and valves to distribute slurry, this application utilizes the kinetic energy generated by the slurry's gravity, impact force on the distribution disc, and centrifugal force to drive the disc's rotation. This avoids manual and electrical control methods for slurry distribution, thereby reducing costs. Furthermore, by using multiple first and second distribution spaces to sequentially perform primary and secondary distribution of the slurry, the distribution efficiency and uniformity are improved.

Detailed Implementation

[0019] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions in the embodiments of this application are described clearly and completely below. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are also within the scope of protection of this application.

[0020] refer to Figures 1 to 4 This application provides a non-powered slurry distributor, comprising: A columnar distribution housing 100 has a support shaft 101 located in the middle of its inner bottom surface, and a feed pipe 102 is connected to the support shaft 101 (the feed pipe 102 is connected to the distribution housing 100; since the feed pipe 102 has a certain length, in order to ensure the stability of the feed pipe 102, the pipe body outside the distribution housing 100 can be supported and fixed by a bracket or the like, not shown in the figure). The top end of the support shaft 101 is rotatably connected to a distribution disc 200 with a diameter smaller than the inner diameter of the distribution housing 100; wherein, the support shaft 101 is fixedly connected to the inner bottom surface of the distribution housing 100.

[0021] Multiple first distribution spaces 300 are evenly spaced around the center of the distribution disk 200 on its upper surface, and each is connected to the bottom of the distribution cylinder 400 located above the center of the distribution disk 200 (the bottom of the distribution cylinder 400 is fixedly connected to the top of the multiple first distribution spaces 300 near the center of the distribution disk 200). The bottom end of the feed pipe 102 extends into the distribution cylinder 400. Since the distribution disk 200 is rotatably mounted on the top of the support shaft 101, the slurry is fed into the feed pipe 102 and then through the feed pipe 102. 02 Entering the distribution cylinder 400, during the process of the slurry flowing from the top to the bottom of the distribution cylinder 400, the gravity of the slurry and the impact force of the slurry on the distribution plate 200 will generate a certain amount of kinetic energy, driving the distribution plate 200, which is rotatably connected to the support shaft 101, to rotate. The multiple first distribution spaces 300 rotate synchronously with the distribution plate 200, causing the slurry flowing out of the multiple first distribution spaces 300 to generate centrifugal force. Under the action of centrifugal force, the distribution plate 200 will be further pushed, and the slurry is distributed in one step through the multiple first distribution spaces 300.

[0022] Multiple second distribution spaces 500 are arranged at equal intervals around the support shaft 101 and are all located below the distribution disk 200. Each second distribution space 500 has a discharge port 501 at its bottom for discharging the slurry that has entered from each first distribution space 300. During the rotation of the distribution disk 200, the multiple first distribution spaces 300 rotate synchronously with it. As the multiple first distribution spaces 300 rotate, the slurry flowing out of them is evenly distributed into the multiple second distribution spaces 500 under the action of centrifugal force, ensuring that the slurry entering the multiple second distribution spaces 500 is uniform. The slurry in each second distribution space 500 is discharged through its discharge port 501, achieving secondary distribution of the slurry and thus improving the distribution efficiency and uniformity of the slurry.

[0023] The non-powered slurry distributor provided in this application introduces slurry into a feed pipe 102, which then enters a distribution cylinder 400. As the slurry flows from the top to the bottom of the distribution cylinder 400, the weight of the slurry and the impact force of the slurry on the distribution disc 200 generate kinetic energy, driving the distribution disc 200, which is rotatably connected to the support shaft 101, to rotate. Multiple first distribution spaces 300 rotate synchronously with the distribution disc 200, causing the slurry flowing out of the multiple first distribution spaces 300 to generate centrifugal force. Under the action of centrifugal force, the distribution disc 200 is further pushed, thus achieving primary distribution of the slurry through the multiple first distribution spaces 300. Furthermore, as the first distribution spaces 300 rotate with the distribution disc 200, the slurry flowing out of each first distribution space 300 uniformly enters multiple second distribution spaces 500. The slurry entering the multiple second distribution spaces 500 is discharged through the outlet 501, thus achieving secondary distribution of the slurry. Compared to existing slurry distributors that use a combination of flow meters and valves to distribute slurry, this application utilizes the kinetic energy generated by the slurry's gravity, the impact force of the slurry on the distribution disc 200, and centrifugal force to drive the distribution disc 200 to rotate. This avoids manual and electrical control methods for slurry distribution, thereby reducing the cost of slurry distribution. Furthermore, by using multiple first distribution spaces 300 and multiple second distribution spaces 500 to sequentially perform primary and secondary distribution of the slurry, the distribution efficiency and uniformity are improved.

[0024] In some embodiments, reference Figure 2 and Figure 4 In this application, a plurality of first distribution plates 201 are evenly spaced around the upper surface of the distribution disk 200. Each first distribution plate 201 has a first preset distance (horizontal distance) between its side away from the outer peripheral wall of the distribution disk 200 and the center of the distribution disk 200. The bottom surface of the distribution cylinder 400 is connected to the top surface of the plurality of first distribution plates 201 (the bottom of the distribution cylinder 400 is fixedly connected to the top of the plurality of first distribution plates 201 near the center of the distribution disk 2500). The purpose of setting the first preset distance is to ensure that the bottom of the distribution cylinder 400 has sufficient space to accommodate the slurry flowing from the bottom of the distribution cylinder 400 onto the upper surface of the distribution disk 200, so that the slurry flowing from the bottom of the distribution cylinder 400 can evenly enter the plurality of first distribution spaces 300 when it reaches the upper surface of the distribution disk 200, thus ensuring the uniformity of the first distribution spaces 300. The first preset distance can be set according to actual conditions, and this application does not specifically limit it.

[0025] Furthermore, the sidewalls of every two adjacent first distribution plates 201 that are close to each other and the upper surface of the distribution disk 200 together form a first distribution space 300. The slurry is distributed in one step through multiple first distribution spaces 300, and the number of first distribution spaces 300 can be set according to the actual distribution of the slurry, but this application does not make a specific limitation on it.

[0026] In some embodiments, reference Figure 2 and Figure 4 In this application, all the first distribution plates 201 are arc-shaped. Compared to straight first distribution plates 201, the first distribution space 300 formed by the two arc-shaped first distribution plates 201, the upper surface of the distribution disk 200, and the outer wall of the support shaft 101 extends along the tangential direction of the distribution disk 200. This allows the slurry flowing into the first distribution space 300 from the bottom of the distribution cylinder 400 to flow out along the tangential direction of the distribution disk 200 within the first distribution space 300. This accelerates the rotation of the distribution disk 200 during the flow of the slurry within the first distribution space 300, while simultaneously allowing the slurry to uniformly enter the multiple second distribution spaces 500 under centrifugal force. Therefore, the arc-shaped first distribution plates 201 improve the uniformity of slurry distribution.

[0027] In some embodiments, the slurry flowing from the bottom of the distribution cylinder 400 to each first distribution space 300 in this application faces the inner wall of one of the first distribution plates 201 of the corresponding first distribution space 300. This causes the slurry to generate a tangential impact force on the first distribution plate 201 in the first distribution space 300 when it flows into the first distribution space 300, which further promotes the rotation of the distribution plate 200, thereby improving the distribution efficiency of the slurry.

[0028] In some embodiments, the first preset distance in this application is 1 / 4 to 1 / 3 of the radius of the distribution disk 200. This is to ensure that the side of the first distribution plate 201 closest to the center of the distribution disk 200 is a certain distance from the center of the distribution disk 200, so that a certain space is formed between the bottom of the distribution cylinder 400 and the upper surface of the distribution disk 200 within this distance. This allows the slurry flowing out from the bottom of the distribution cylinder 400 to first enter this space and then uniformly enter the multiple second distribution spaces 500, thereby improving the continuity of the slurry distribution process. If the first preset distance is too large, the first slurry will stay in each first distribution space 300 for a short time, which is not conducive to the distribution of the slurry. If the first preset distance is too small, the volume of the space formed between the bottom of the distribution cylinder 400 and the upper surface of the distribution disk 200 within this distance will be small, and it cannot hold a large volume of slurry. Therefore, the value of the first preset distance needs to be within a suitable range. The first preset distance is 1 / 4 to 1 / 3 of the radius of the distribution disk 200. This not only ensures the uniformity of slurry distribution, but also ensures that the space formed between the bottom of the distribution cylinder 400 and the upper surface of the distribution disk 200 within this distance can accommodate enough slurry, thus ensuring the continuity of the slurry distribution process by multiple first distribution spaces 300.

[0029] In some embodiments, reference Figure 3 In this application, the inner bottom surface of the distribution shell 100 is provided with a plurality of second distribution plates 103 at equal intervals around the support shaft 101. The top of each second distribution plate 103 is a second preset distance from the lower surface of the distribution disk 200. The second distribution plates 103 and the second preset distance are set to ensure that while the second distribution space 500 is formed, the inner bottom surface of the second distribution space 500 is a certain distance from the lower surface of the distribution disk 200. This distance allows the slurry flowing out of the plurality of first distribution spaces 300 to flow into the plurality of second distribution spaces 500 again after a certain time interval, thereby making the slurry flowing into the plurality of second distribution spaces 500 from the plurality of first distribution spaces 300 more uniform.

[0030] Furthermore, the sidewalls of every two adjacent second distribution plates 103, together with the inner bottom surface and inner wall of the distribution housing 100 and the outer wall of the support shaft 101, form a second distribution space 500. Multiple second distribution spaces 500 can perform secondary distribution of the slurry, thereby improving the uniformity of the slurry. The number of second distribution spaces 500 can be set according to actual conditions, and this application does not impose a specific limitation on it.

[0031] In some embodiments, the second preset distance in this application is 10cm to 25cm. If the second preset distance is too small, the slurry flowing out of multiple second distribution spaces 500 may quickly enter the second preset distance, reducing the slurry distribution time and resulting in lower slurry uniformity. Conversely, if the second preset distance is too large, the slurry flowing from the first distribution space 300 into the second distribution space 500 may exert a large impact force on the second distribution space 500, causing wear on the inner bottom surface of the second distribution space 500. Therefore, the value of the second preset distance should be within a suitable range. A second preset distance between 10cm and 25cm not only ensures the uniformity of slurry distribution but also reduces the impact force and wear on the inner bottom surface of the second distribution space 500. The value of the second preset distance can be set according to actual conditions; the second preset distance in the applicant's non-powered slurry distributor is typically 20cm.

[0032] In some embodiments, reference Figure 3 and Figure 4 In this application, the lower surface of the distribution disk 200 is provided with a connecting shaft 202, and the bottom end of the connecting shaft 202 is rotatably connected to the top end of the support shaft 101 through a bearing 600. The top end of the support shaft 101 is fixedly connected to a bearing seat, and the bearing 600 is fixedly connected to the bearing seat.

[0033] In the above embodiment, the bearing seat is fixed to the top of the support shaft 101, and the bearing 600 is fixed on the upper surface of the bearing seat. The end of the connecting shaft 202 away from the distribution disk 200 is installed in the bearing 600 (wherein, the outer diameter of the connecting shaft 202 is adapted to the inner diameter of the bearing 600). Therefore, under the action of the gravity of the slurry and the impact force of the slurry on the distribution disk 200, a certain kinetic energy will be generated. This kinetic energy drives the distribution disk 200, which is rotatably connected to the bearing 600 through the connecting shaft 202, to perform circumferential movement, thereby realizing the rotation of the distribution disk 200.

[0034] In some embodiments, reference Figure 1 Each discharge port 501 in this application is connected to a slurry pipe 700, and the end of the slurry pipe 700 away from the discharge port 501 is used to connect to a slurry utilization device; wherein, the slurry utilization device can be a spiral concentrator, a flotation machine, etc., depending on the actual situation, and this application does not specifically limit it.

[0035] The first slurry pump 701 is installed on the slurry pipe 700.

[0036] In the above embodiment, after the slurry sequentially enters multiple second distribution spaces 500 through multiple first distribution spaces 300, the slurry in each second distribution space 500 flows out through its discharge port 501 and enters the slurry pipe 700 connected to the discharge port 501. Under the power provided by the first slurry pump 701, the slurry enters the slurry utilization device through the slurry pipe 700, thereby achieving the purpose of further processing the slurry entering the device.

[0037] In some embodiments, reference Figure 1 , Figure 2 and Figure 4 In this application, the end of the feed pipe 102 away from the distribution shell 100 is used to connect to the slurry production device; wherein, the slurry production device includes, but is not limited to, ball mills and mining agitators.

[0038] The feed pipe 102 is equipped with a second slurry pump 1021.

[0039] In the above embodiment, slurry is generated by the slurry production device. After entering the feed pipe 102, the slurry enters the distribution cylinder 400 under the power of the second slurry pump 1021, thereby realizing the continuity of slurry transportation. The slurry flows evenly into multiple first distribution spaces 300 through the bottom of the distribution cylinder 400, and the slurry is evenly distributed in the first distribution space 300. After being evenly distributed in the multiple first distribution spaces 300, the slurry enters the second distribution space 500, and the slurry is evenly distributed in the second distribution space 500, thereby improving the distribution efficiency and uniformity of the slurry.

[0040] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
