[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] Reference Figure 1 and Figure 2, the utility model provides an embodiment: a horizontal vibrating centrifuge screen basket leakage prevention device, including a basket body 1, a disc 3 is arranged on the left side of the interior of the basket body 1, a hollow column 4 is rotatably connected to the left side of the disc 3, the right end of the hollow column 4 passes through the disc 3, the upper and lower sides of the hollow column 4 are fixedly connected to support rods 5, and the ends of the two support rods 5 that are far away are fixedly connected to arc scrapers 6, the front and rear ends of the right side of the disc 3 are rotatably connected to the rotating shaft 7, the right side of the rotating shaft 7 is fixedly connected to the movable rod 8, the front and rear sides of the hollow column 4 are fixedly connected to the hydraulic rod 9, and the output ends of the two hydraulic rods 9 are respectively fixedly connected to one side of the corresponding movable rod 8, a disassembly mechanism 2 is arranged inside the disc 3, the size of the disc 3 matches the size of the inner left side of the basket body 1, the two arc scrapers 6 and the support rod 5 are inclined, and the sizes of the two arc scrapers 6 match the internal size of the basket body 1;

[0031] Specifically, the basket body 1 can rotate with the rotation of the hollow column 4. This design enables the arc-shaped scraper 6 on the hollow column 4 to effectively scrape the inner wall of the basket body 1. In this way, not only can the materials on the inner wall of the basket body 1 be cleaned in time, but also the risk of blockage is reduced. In addition, the device is also equipped with a hydraulic rod 9, which can drive the movable rods 8 on both sides to swing left and right to knock the basket body 1. This design is intended to further prevent the basket body 1 from being blocked during use. In actual operation, this knocking method can effectively loosen the blocked materials and ensure the smooth progress of the screening process.

[0032] Reference Figure 2 and Figure 3 The disassembly mechanism 2 includes an opening groove 201, and the two opening grooves 201 are respectively opened on the upper and lower sides of the inner part of the disc 3. The upper and lower ends of the left side of the disc 3 are rotatably connected with a rotating rod 202. The right ends of the two rotating rods 202 respectively penetrate the corresponding opening grooves 201 and are fixedly connected with a driving bevel gear 203. A screw rod 204 is rotatably connected to one side of the inner part of the opening groove 201. A driven bevel gear 205 is fixedly connected to the outer side of the screw rod 204. The driven bevel gears 205 are respectively meshed with the corresponding driving bevel gears 203. The outer side of the screw rod 204 is threadedly connected with a limiting rod 206. The ends of the two limiting rods 206 that are far away from each other respectively penetrate the upper and lower ends of the left side of the basket body 1.

[0033] Specifically, when the basket body 1 is damaged and needs to be replaced, the rotating rod 202 can drive the active bevel gear 203 to rotate. This design makes the driven bevel gear 205 rotate as well, thereby driving the screw rod 204 to rotate. In this process, the most critical link is the role of the limit rod 206. When the screw rod 204 rotates, the limit rod 206 will be separated from the basket body 1 and enter the open groove 201. This design enables the limit rod 206 to effectively release the limit fixation of the basket body 1. In this way, it becomes very simple to disassemble and replace the basket body 1, thereby improving the practicality of the device.

[0034] Reference Figure 3 and Figure 4 The front and rear sides of the two limit rods 206 are fixedly connected with sliders 207, and the front and rear sides of the two opening slots 201 are provided with slide grooves 208, and the sliders 207 are slidably connected with the corresponding slide grooves 208 respectively;

[0035] Specifically, the sliding groove 208 can limit the moving track of the limiting rod 206 so that it can move more smoothly.

[0036] Reference Figure 1 , the hollow column 4 and the hydraulic rod 9 are electrically connected to the external controller;

[0037] Specifically, the operation of the hollow column 4 and the hydraulic rod 9 can be controlled by an external controller.

[0038] Reference Figure 1 and Figure 2 , a sealing ring 10 is fixedly connected to the outer right end of the basket body 1;

[0039] Specifically, the sealing ring 10 can prevent relatively large particles of clean coal from being thrown out from the gap to between the centrifuge casing and the basket 1 to cause the problem of coarse coal leakage and clean coal loss.

[0040] Working principle: When using the basket 1, first connect the hollow column 4 to the external horizontal vibrating centrifuge, and then start the horizontal vibrating centrifuge. At this time, the material will enter the hollow column 4 through the horizontal vibrating centrifuge, and finally flow into the basket 1. The basket 1 will rotate with the rotation of the hollow column 4, and the arc-shaped scraper 6 on the hollow column 4 will scrape the inner wall of the basket 1. At the same time, starting the hydraulic rod 9 can drive the movable rods 8 on both sides to swing left and right to knock the basket 1, which can further prevent the basket 1 from being blocked. The basket 1 is not easily blocked by materials when in use, so it will not affect The material screening efficiency of the device is affected, thereby being able to meet the needs of users, and when the basket body 1 is damaged and needs to be replaced, the rotating rods 202 on the upper and lower sides are rotated first to drive the active bevel gear 203 on the outer side thereof to rotate, and the driven bevel gear 205 will also rotate accordingly due to the engagement with the active bevel gear 203, and the screw rod 204 will rotate accordingly. At this time, the limiting rod 206 on the screw rod 204 will be separated from the basket body 1 and enter the open groove 201, so that the limiting fixation of the basket body 1 can be released, and the disassembly and replacement of the basket body 1 is relatively simple, thereby improving the practicality of the device.
