DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model; it is obvious that the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments of the utility model without making creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-Figure 4 , Figure 1 It is an overall schematic diagram of the utility model; a device for preventing segregation of filling slurry in underground mines, comprising a feed portion 1; a mounting portion 2, connected to the feed portion 1; a discharge portion 4, the discharge portion 4 comprising a vertical portion 401 and an inclined portion 402, the vertical portion 401 being rotatably connected to the mounting portion 2, the feed portion 1 extending to the inside of the vertical portion 401, and the feed portion 1 and the vertical portion 401 are sealed, and the inclined portion 402 is connected to the vertical portion 401; a rotating portion 3, mounted on the mounting portion 2, the rotating portion 3 is connected to the discharge portion 4, and is configured so that when the rotating portion 3 drives the discharge portion 4 to rotate, the filling slurry is ejected through the vertical portion 401 and the inclined portion 402.

[0022] Please refer to Figure 2 Figure 3 , an annular plate 201 is installed on the discharge part 4; multiple bearings 202, the inner ring of which is connected to the mounting part 2, and the outer ring is connected to the vertical part 401, so that the discharge part 4 can rotate through the bearings 202; multiple cylindrical bearings 203 are installed inside the discharge part 4, the top of the cylindrical bearing 203 is connected to the mounting part 2, and the outer ring of the cylindrical bearing 203 is connected to the feed part 1 and the vertical part 401.

[0023] The annular plate 201 and the discharge part 4 are connected by welding to provide high strength and sealing. The bearing 202 is connected to the vertical part 401 of the mounting part 2 through the inner and outer rings respectively. Compared with the traditional connection method, this connection method is suitable for pipeline systems that require frequent rotation. For the cylindrical bearing 203, deep groove ball bearings or cylindrical roller bearings are selected, which are not only suitable for pipeline systems that rotate frequently, but also the connection has a larger load-bearing capacity.

[0024] refer to Figure 3, a ring motor 301 is mounted on the mounting portion 2 ; a pinion 302 is connected to the ring motor 301 ; an outer gear 303 is mounted outside the discharge portion 4 , and is configured so that the outer gear 303 is meshed with the pinion 302 .

[0025] The annular motor 301 drives the pinion 302 to rotate, and the pinion meshes with the external gear 303 outside the discharge part 4, and the external gear 303 drives the discharge part 4 to rotate. The annular motor 301 can provide a large torque, and the pinion 302 uses a high-precision gear to improve the transmission efficiency. Compared with the transmission rotation device in the rotation design that requires a large torque output, this design has obvious advantages, with stronger transmission capacity, more space saving, and avoids contact with the internal filling slurry.

[0026] refer to Figure 2 Figure 3 , an annular groove 204 is opened inside the annular plate 201; multiple pulleys 205 are installed on the annular groove 204; a T-shaped disc 206 is connected to the external gear 303, and is configured so that when the external gear 303 rotates, the T-shaped disc 206 rotates on the annular groove 204 through the multiple pulleys 205.

[0027] A plurality of pulleys 205 are installed inside the annular groove 204. A T-shaped disc 206 is installed on the bottom of the pulley 205 and connected to the external gear 303 to realize motion transmission, so that the T-shaped disc 206 can move in the annular groove 204. At the same time, multiple pulleys disperse the load and increase the load-bearing capacity of the entire rotating device.

[0028] refer to Figure 4 A two-way elbow 403 has one end connected to the vertical portion 401 and the other end connected to the inclined portion 402; a wave thread 404 is provided inside the inclined portion 402 to slow down the flow speed of the material.

[0029] The bidirectional elbow 403 is made of stainless steel, lining type, cast iron, etc. These materials are corrosion-resistant, high in strength, wear-resistant and shock-absorbing, and have high conveying efficiency. The shape of the wave thread 404 slows down the flow speed of the material so that the filling slurry thrown out during rotation is more uniform and sufficient.

[0030] refer to Figure 4 The semicircular opening 405 is opened on the inclined portion 402 and is configured such that the semicircular opening 405 extends to the two-way elbow 403 and connects one end of the inclined portion 402 .

[0031] The design of the semicircular opening 405 reduces the pressure accumulation during the conveying process of the filling slurry. At the same time, the semicircular opening 405 will cause local disturbance of the filling slurry during the rotation process to further prevent segregation, and the edge of the semicircular opening 405 is rounded.

[0032] refer to Figure 4A plurality of annular grooves 406 are provided on the bidirectional elbow 403 ; a plurality of annular gaskets 407 are installed inside the annular grooves 406 and are fixedly connected to the vertical portion 401 and the inclined portion 402 .

[0033] The annular gasket 407 provides a good sealing effect, and absorbs part of the vibration to reduce the vibration of the rotating system and reduce stress concentration. The annular gasket 407 can be replaced separately for easy maintenance, and the surface of the annular groove 406 is specially treated to improve the overall sealing performance.

[0034] refer to Figure 2 , a sealing ring 101 is installed on the vertical portion 401 , and the sealing ring 101 is fixedly connected to the feeding portion 1 .

[0035] The sealing ring 101 is made of various materials such as PTFE, polyurethane, EPDM, etc., to ensure that the filling slurry does not leak, can resist the wear of the filling slurry, and can adapt to the vibration of the equipment.

[0036] When the utility model is a device for preventing segregation of filling slurry in underground mines, the filling enters the discharging part 4 through the feeding part 1. At this time, the rotating part 3 starts to work, driving the discharging part 4 to rotate. When the filling slurry inside the discharging part 4 reaches the inclined part 402, it is thrown out by rotation, thereby preventing the filling slurry from being segregated due to impact at one place.

[0037] The above is only a preferred specific implementation of the utility model; however, the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and improved ideas of the utility model within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model.
