Description

Technical Field

[0001] The utility model belongs to the technical field of cyclone feed branch pipes, in particular to a cyclone feed branch pipe with stable flow. Background Art

[0002] The hydrocyclone is a common separation and classification equipment, and its principle is centrifugal sedimentation. When the two-phase mixed liquid to be separated enters the hydrocyclone from the periphery of the hydrocyclone at a certain pressure, a strong three-dimensional elliptical strong rotational shear turbulent motion occurs. Due to the difference in particle size between coarse particles and fine particles, they are subjected to different forces such as centrifugal force, centripetal buoyancy and fluid drag. Under the action of centrifugal sedimentation, most of the coarse particles are discharged through the bottom flow port of the hydrocyclone, while most of the fine particles are discharged through the overflow pipe, thereby achieving the purpose of separation and classification.

[0024] The locking assembly includes a guide rod 10, a support seat 9, a threaded barrel 11, a threaded rod 12, a first bevel gear 13, a second bevel gear 14, a third gear 15, a gear ring 16, a rotating shaft 17, a bearing seat 18 and a slot 19. The circumferential surface of the tube body 2 is fixedly connected with a plurality of bearing seats 18, the interiors of the plurality of bearing seats 18 are rotatably connected with the rotating shafts 17, the left ends of the plurality of rotating shafts 17 are fixedly connected with the second bevel gear 14, the right ends of the plurality of rotating shafts 17 are fixedly connected with the third gear 15, the circumferential surface of the tube body 2 is rotatably connected with the gear ring 16, the gear ring 16 is meshed with the third gear 15, the circumferential surface of the tube body 2 is rotatably connected with a plurality of threaded barrels 11, and the plurality of threaded barrels The circumferential surfaces of the plurality of threaded cylinders 11 are fixedly connected with the first bevel gears 13, and the plurality of first bevel gears 13 are respectively meshed with the plurality of second bevel gears 14, the interiors of the plurality of threaded cylinders 11 are threadedly connected with the threaded rods 12, the ends of the plurality of threaded rods 12 away from the annular liner 4 are fixedly connected with the guide rods 10, the plurality of guide rods 10 extend toward the ends away from the threaded rods 12 and penetrate the threaded cylinders 11, the right side of the flange 7 is fixedly connected with the support seat 9, the guide rod 10 penetrates the support seat 9 and is slidably connected with the support seat 9, the threaded rod 12 extends into the tube body 2, the circumferential surface of the annular liner 4 is provided with a slot 19, and the threaded rod 12 is connected to the annular liner 4 through the slot 19.

[0025] During operation, firstly, an annular liner 4 is installed inside the pipe body 2. At the same time, with the cooperation of the first rubber pad 5 on the right side, the annular liner 4 can be connected to the rubber liner 25. Then, the locking assembly is manually controlled to operate. Under the action of the locking assembly, the annular liner 4 can be firmly installed in the pipe body 2. Then, the flange 7 on the left side of the pipe body 1 is connected to the feed port of the cyclone. The flange 7 on the right side of the pipe body 1 is fixedly connected to the flange 8 on the left side of the pipe body 2 by bolts, so that the pipe body 1 and the pipe body 2 are fixedly connected. The first and second tube bodies 2 are firmly connected together. At this time, the tube body 1 and the tube body 2 can constitute the feed branch of the cyclone; when the tube body 1 and the tube body 2 are connected, the annular liner 4 will extend into the tube body 1, and the first rubber pad 5 on the left will fit tightly with the rubber lining 1 3. Under the action of the first rubber pad 5 on the left, the annular liner 4 is connected with the rubber lining 1 3. When the feed branch is used to feed the material to be separated, the fluid passes through the inside of the feed branch, and its minimum fluid cross-section is at the inner wall of the raised ring 6. The inner diameter determines the fluid flow rate. When the fluid flow rate is large, the raised ring 6 is deformed due to the pressure, the volume is reduced, the inner diameter is increased, the flow area is increased, and the fluid flow rate is slowed down, thereby playing a deceleration and regulation role. Vice versa, due to the elastic effect of the raised ring 6, the inner diameter can be adjusted, so that the flow rate of the slurry can be adaptively adjusted, which plays a role in stabilizing the flow rate, thereby enhancing the stability of the cyclone and improving the classification and separation indicators; when the raised ring 6 is damaged by the impact of the material, first separate the pipe body 1 and the pipe body 2 2, and then manually control the locking assembly, specifically, rotate the gear The circle 16 drives the third gear 15 to rotate, and then drives the second bevel gear 14 to rotate with the cooperation of the rotating shaft 17, thereby driving the first bevel gear 13 to rotate, and the threaded tube 11 is driven to rotate under the action of the first bevel gear 13. At this time, the threaded rod 12 can be stably moved along the slot 19 away from the annular liner 4 with the cooperation of the guide rod 10 and the support seat 9, until the threaded rod 12 is completely separated from the annular liner 4, the annular liner 4 can be pulled out of the tube body 2, and the raised ring 6 can be removed from the annular liner 4 for replacement.

[0026] The utility model provides a flow-stabilized cyclone feed branch pipe. Compared with the prior art, under the action of the locking assembly, the annular liner 4 and the raised ring 6 can be ensured to be firmly installed in the pipe body 2. When the raised ring 6 is damaged by the impact of the material, after the pipe body 1 and the pipe body 2 are separated, the locking assembly can be manually controlled to release the fixation of the annular liner 4, and the annular liner 4 and the raised ring 6 can be removed, and the raised ring 6 can be replaced alone, thereby saving costs.

The right end of the ring gear 16 is fixedly connected with a threaded shaft 22, and the threaded shaft 22 is connected to the second limit plate 21 through the second clamping hole 24. The first clamping hole 23 and the second clamping hole 24 have the same size. During operation, when the threaded shaft 22 is connected to the second limit plate 21 through the second clamping hole 24, the threaded rod 12 can be ensured to be connected to the annular lining plate 4 through the slot 19, thereby ensuring that the threaded rod 12 is stably connected to the annular lining plate 4, and a nut can be installed on the circumferential surface of the threaded shaft 22 so that the ring gear 16 is stably in this position, thereby preventing the ring gear 16 from rotating. When the ring gear 16 drives the threaded shaft 22 to connect with the first limit plate 20 through the first clamping hole 23, the threaded rod 12 just moves to a state of being disengaged from the annular lining plate 4, and it is convenient to remove the annular lining plate 4 at this time. Therefore, under the mutual cooperation of the first limit plate 20, the second limit plate 21, the first clamping hole 23 and the second clamping hole 24, it can be ensured that the annular lining plate 4 is more firmly and accurately installed in the pipe body 2, and the position of the threaded rod 12 can be more accurately controlled, thereby facilitating the installation or removal of the annular lining plate 4.

[0028] In another embodiment of the present invention, refer to Figure 1 The rubber lining 1 3 and the rubber lining 2 25 are made of the same material, which is corrosion-resistant rubber. When working, the corrosion resistance of the rubber lining 1 3 and the rubber lining 2 25 can be improved.

[0029] The above are only preferred embodiments of the present invention and are not intended to limit the present invention.
