Description

Technical Field

[0001] This utility model relates to the field of screening equipment technology, specifically a vibrating screening cycle test system. Background Technology

[0002] With the continuous improvement of technological levels and the ongoing development of production technologies across various industries, the market's requirements for the types, models, quality, and performance of vibrating screen products have become increasingly stringent and diversified. To ensure that the quality of ore meets the expected standards during the screening process, it is essential to strictly control and optimize the separation effect of the vibrating screen to ensure uniform particle size distribution of the screened ore, thus meeting the needs of subsequent processes.

[0003] In traditional ore sampling, technicians need to frequently travel between various production processes in the factory to collect and analyze samples. This not only increases workload but also brings many inconveniences. Especially in the ore sorting industry, particularly large factories, the high cost and risk of testing screen equipment often prevent them from easily building large-scale sorting lines for trials. Therefore, most companies prefer to use smaller-scale testing systems for initial verification. However, this cumbersome operation of traveling between different processes in the factory for sampling not only consumes a significant amount of human resources but also significantly increases time costs, impacting production efficiency.

[0004] Furthermore, existing screening devices typically only allow for single-pass screening and cannot perform multiple-cycle screening, leading to potentially significant instability in sampling results and consequently reducing the accuracy and reliability of test results. This limitation, to some extent, restricts the optimization and improvement of ore screening processes.

[0005] To address the aforementioned problems, this invention proposes an innovative vibrating screen cyclic testing system. This system aims to improve the stability of the screening effect and the accuracy of the test results through cyclic screening, thereby effectively solving the shortcomings of traditional screening devices and enhancing the overall level of ore screening technology. Utility Model Content

[0006] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a vibrating sieving cyclic test system, which can cyclically sieve materials, which helps to stabilize the sampling results and improve the accuracy of the test results.

[0007] The technical solution adopted by this utility model to solve its technical problem is: A vibrating screen cyclic test system includes a vibrating screen, a support frame, and a mixing tank. The vibrating screen is placed on the support frame, and the mixing tank is placed on one side of the vibrating screen. The bottom of the mixing tank is connected to the inlet of the vibrating screen via a slurry pump. The vibrating screen includes an oversize discharge port and an undersize discharge port, which are respectively connected to the inlet of the mixing tank.

[0008] Compared with the prior art, the beneficial effects of this utility model are: This invention connects the oversize and undersize discharge ports of a vibrating screen to the inlet of a mixing tank, respectively. A slurry pump then pumps the slurry from the mixing tank to the vibrating screen, creating a closed-loop circulation system. This allows the slurry to continuously circulate between the mixing tank and the vibrating screen, ensuring thorough sieving of solid particles. This method improves the stability of the sieving effect, avoids sieving deviations caused by uneven slurry distribution, and significantly enhances the accuracy of the experimental setup, making the test results more reliable and valuable.

[0010] Preferably, the mixing tank and the slurry pump are connected by a connecting pipe one, and the slurry pump and the vibrating screen are connected by a connecting pipe two, with a flow meter installed on the connecting pipe two.

[0014] The present invention will be further described below with reference to specific embodiments. The purpose of this description is only to better understand the content of the present invention. Therefore, the examples given do not limit the scope of protection of the present invention.

[0015] like Figure 1 , Figure 2 As shown, a vibrating screen cyclic test system consists of a vibrating screen 1, a support frame 2, and a stirring tank 3. The vibrating screen 1 is placed above the support frame 2. In this embodiment, the stirring tank 3 is placed on one side of the vibrating screen 1.

[0016] The bottom of the mixing tank 3 is set as a conical structure, and the bottom of the mixing tank 3 is connected to one end of the slurry pump 5 through the connecting pipe 1 4. The other end of the slurry pump 5 is connected to the feed port of the vibrating screen 1 through the connecting pipe 2 6. A flow meter 7 is installed on the connecting pipe 2 6 to control the discharge of the connecting pipe 2 6.

[0017] The vibrating screen 1 is equipped with an oversize discharge port 8 and an undersize discharge port 9, which are respectively connected to the inlet of the mixing tank 3.

[0018] A stirring motor 10 is installed on the top of the mixing tank 3. The output end of the stirring motor 10 is connected to a stirring shaft 11. The stirring shaft 11 extends downward into the interior of the mixing tank 3, and several stirring rods are vertically arranged on the outer wall of the stirring shaft 11. When the stirring motor 10 rotates, it drives the stirring shaft 11 to rotate, thereby causing the stirring rods to stir the slurry in the mixing tank 3.

[0019] A detachable end cap can also be installed on the top of the mixing tank 3. The mixing shaft 11 passes through the end cap and is rotatably connected to the end cap. A water inlet pipe is provided on the end cap. The inner end of the water inlet pipe is connected to the inside of the mixing tank 3, and the outer end of the water inlet pipe is connected to the water supply system.

[0020] A walkway 12 is also provided on one side of the mixing tank 3, and guardrails 13 are provided on both sides of the walkway 12. Operators can climb onto the walkway 12 to observe and take samples.

[0021] In this embodiment, the materials required for the initial test and a certain proportion of water are first added to the mixing tank 3. Then, the entire system is powered on, the stirring motor 10 is started, and the mixing rod is used to rotate to mix the materials. Then, the vibrating screen 1 and the slurry pump 5 are started. The slurry in the mixing tank 3 is transported to the screen surface of the vibrating screen 1 under the drive of the slurry pump 5. Under the action of the vibrating screen 1, the materials are classified by different forces. The materials larger than the screen mesh of the vibrating screen 1 move forward along the screen surface and are finally discharged into the mixing tank 3 from the oversize discharge port 8. The materials smaller than the screen mesh fall through the mesh and are discharged into the mixing tank 3 from the undersize discharge port 9. After this cycle is repeated until the materials are mixed evenly and stably, samples can be taken from either discharge port (oversize discharge port 8 or undersize discharge port 9) for sample analysis.

[0022] This invention connects the oversize and undersize discharge ports of a vibrating screen to the inlet of a mixing tank, respectively. A slurry pump then pumps the slurry from the mixing tank to the vibrating screen, creating a closed-loop circulation system. This allows the slurry to continuously circulate between the mixing tank and the vibrating screen, ensuring thorough sieving of solid particles. This method improves the stability of the sieving effect, avoids sieving deviations caused by uneven slurry distribution, and significantly enhances the accuracy of the experimental setup, making the test results more reliable and valuable.

[0023] The above description is merely a preferred embodiment of the present utility model and does not limit the scope of the present utility model. All equivalent changes made based on the content of the present utility model specification and its drawings are included within the scope of the present utility model.
