Description

Technical Field

[0001] This utility model relates to the field of hydrocyclone technology, and in particular to a tailings desliming hydrocyclone. Background Technology

[0002] Tailings desliming hydrocyclones are commonly used solid-liquid separation devices, mainly used for separating and desliming tailings containing slurry or fine particles. They are applicable to many industries, including mining, sand and gravel production, and wastewater treatment.

[0003] According to Chinese Patent Publication No. CN220759590U, a tailings desliming hydrocyclone is provided, belonging to the technical field of desliming hydrocyclones. This tailings desliming hydrocyclone includes a hydrocyclone body, with a feed inlet fixedly installed on one side surface of the hydrocyclone body. A rotating shaft is rotatably installed inside the hydrocyclone body, with one end extending to the top surface of the hydrocyclone body. A first cleaning component includes a water pump, with an external pipe fixedly connected to the water pump's inlet and a water delivery pipe fixedly connected to the water pump's outlet, one end of which extends into the interior of the hydrocyclone body. This invention, by starting the water pump, delivers water to the interior of the water delivery pipe. The water is continuously input into the interior of the water distribution frame through the water delivery pipe, causing the pressure inside the water distribution frame to continuously increase. Subsequently, the water inside the water distribution frame is sprayed through nozzles onto the inner wall of the hydrocyclone body, cleaning the inner wall of the hydrocyclone body.

[0004] It is known that traditional hydrocyclones, for ease of cleaning, have nozzles mounted on the internal spiral blades. As a key component, the performance of the nozzle directly affects the efficiency and effectiveness of the entire system. Traditional nozzle devices are typically fixed in one position, achieving the spraying function through high-pressure water flow. However, this design has several limitations: when not in use, the nozzles are exposed and susceptible to environmental influences; for example, impurities such as mud and sand may enter the nozzle, causing blockage or damage. Utility Model Content

[0005] The purpose of this utility model is to provide a tailings desliming hydrocyclone that can avoid the nozzle being exposed to the outside environment when not in use, which is easily affected by external environmental factors, such as impurities such as mud and sand that may enter the nozzle and cause blockage or damage.

[0006] This utility model provides a tailings desliming hydrocyclone, including a shell, with a feed inlet and a water inlet respectively opened at the upper end of the shell. The shell is provided with a spiral blade, which has a hollow structure inside. Multiple through holes are opened on one side of the spiral blade. A sealing shell is provided inside the spiral blade. A water pipe is fixedly installed on one side of the sealing shell. Multiple nozzles are installed on one side of the water pipe. A hollow tube is fixedly installed at the upper end of the water pipe. The hollow tube passes through the spiral blade and extends to the outside of the shell. The hollow tube is rotatably connected to the spiral blade and the shell.

[0007] Preferably, the hollow tube is used to connect to an external water source, and a gear one is connected to the upper end of the hollow tube, and a gear two is rotatably provided at the upper end of the outer shell. The gear one and the gear two mesh, and the gear two is driven by a motor.

[0008] Preferably, the position of the nozzle corresponds one-to-one with the position of the through hole.

[0009] Preferably, an extension tube is slidably installed inside one or more of the nozzles.

[0010] Preferably, the multiple extension tubes are connected by a connecting rod, and both ends of the connecting rod are connected to a connecting rod. One end of the connecting rod is fixedly connected to the slider. Hollow rods are provided on both the upper and lower sides of the sealing shell, and the slider is slidably disposed in the sliding hole opened in the hollow rod.

[0011] Preferably, a lead screw is rotatably installed inside the hollow rod, and the lead screw is threadedly connected to the slider. The lead screw is driven by a micro motor.

[0012] The tailings desliming hydrocyclone provided in this embodiment of the invention has the following advantages compared to the prior art:

[0013] This invention utilizes the meshing of gear one and gear two to rotate the hollow tube, which in turn rotates the sealing shell and water pipe. When the nozzle is not in use, the sealing shell is rotated to the through hole, and the nozzle is rotated to the inside, thus preventing mud and sand from entering the nozzle. When the nozzle is rotated to the through hole, the sliding of the slider inside the hollow rod allows the connecting rod to slide out with the extension tube, connecting the extension tube to the through hole, thereby facilitating the rinsing of the inner wall of the outer shell.

[0023] The following detailed description, in conjunction with the accompanying drawings, outlines some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0024] Please refer to Figures 1-6 This utility model provides a tailings desliming hydrocyclone, including a shell 1, with a feed inlet 2 and a water inlet 3 respectively opened at the upper end of the shell 1, and a spiral blade 4 arranged inside the shell 1.

[0025] The spiral blade 4 has a hollow internal structure. Multiple through holes 5 are provided on one side of the spiral blade 4. A sealing shell 6 is provided inside the spiral blade 4. The sealing shell 6 is a cylindrical structure with an opening on one side. The sealing shell 6 can seal the through holes 5. A water pipe 10 is fixedly provided on one side of the sealing shell 6. Multiple nozzles 11 are installed on one side of the water pipe 10.

[0026] The position and number of nozzles 11 correspond one-to-one with the position and number of through holes 5. When nozzles 11 correspond to through holes 5, an external water source can be connected through the hollow pipe 7 fixedly installed at the upper end of water pipe 10, water can be introduced into water pipe 10, and then sprayed into the interior of outer shell 1 through nozzles 11, which facilitates rinsing of the interior of outer shell 1.

[0027] The hollow tube 7 extends through the spiral blade 4 to the outside of the outer shell 1. The hollow tube 7 is rotatably connected to the spiral blade 4 and the outer shell 1. At the same time, a gear 8 is connected to the upper end of the hollow tube 7, and a gear 9 is rotatably provided at the upper end of the outer shell 1. The gear 8 and the gear 9 mesh with each other. The gear 9 is driven by a motor. Therefore, by rotating the gear 8, the gear 8 causes the hollow tube 7 to rotate, thereby adjusting the position of the sealing shell 6 and the nozzle 11. When the nozzle 11 is rotated to the through hole 5, it is convenient to rinse the inside of the outer shell 1. When the sealing shell 6 is rotated to the through hole 5, the sealing shell 6 can be used to seal the through hole 5, thereby preventing mud and sand from entering the nozzle 11.

[0028] Furthermore, an extension tube 12 is slidably installed inside multiple nozzles 11. After the extension tube 12 is slid out, it can be connected to the through hole 5 to improve the rinsing effect of the outer casing 1.

[0029] To enable multiple extension tubes 12 to move simultaneously, they are connected by a connecting rod 13. Both ends of the connecting rod 13 are connected to connecting rods 18, one end of which is fixedly connected to a slider 17. Hollow rods 14 are provided on both the upper and lower sides of the sealing shell 6. The slider 17 is slidably disposed in the sliding hole opened in the hollow rod 14. At the same time, a lead screw 15 is rotatably disposed in the hollow rod 14. The lead screw 15 is threadedly connected to the slider 17. The lead screw 15 is driven by a micro motor 16. Driven by the micro motor 16, the lead screw 15 rotates, thereby causing the slider 17 to move automatically with the connecting rod 18, thus causing the extension tubes 12 to slide.

[0030] In summary, the working principle of the tailings desliming hydrocyclone of this utility model embodiment is as follows: When cleaning the outer shell 1, the meshing of gear 8 and gear 9 causes gear 8 to rotate the hollow tube 7, which in turn causes the hollow tube 7 to rotate the sealing shell 6 and the water pipe 10. The sealing shell 6 is rotated to the inner side of the spiral blade 4, and the nozzle 11 is rotated to the through hole 5. Then, the micro motor 16 drives the lead screw 15 to rotate, causing the slider 17 to move with the connecting rod 18, which in turn causes the string rod 13 to slide with multiple extension tubes 12 to the through hole 5. At this time, external water is introduced through the hollow tube 7, and the nozzle 11 can rinse the inside of the outer shell 1.

[0031] When the nozzle 11 is not in use, rotate the sealing shell 6 to the through hole 5 and rotate the nozzle 11 to the inside to prevent mud and sand from entering the nozzle 11.

[0032] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
