Description

Technical Field

[0001] This utility model relates to a slurry distributor, belonging to the field of distributors. Background Technology

[0002] Slurry distributors are commonly used in the mining industry, especially in ore processing. Their main function is to evenly distribute slurry (a mixture of ore and water) to different equipment or areas. This type of distributor improves the efficiency of slurry processing, ensures balanced load across processing stages, and prevents overloading of certain equipment or areas.

[0003] Chinese utility model patent CN2928447Y discloses a rotary slurry distributor, comprising a rotating container with an inlet for slurry entry at the top. The key feature is a guide structure on the side wall of the rotating container, which is inclined at an angle relative to the horizontal direction along the tangential direction of the rotating container. As the slurry falls, it flows through the guide structure, and the gravity of the slurry exerts a tangential force on the guide structure, causing the rotating container to rotate. This rotary slurry distributor can achieve uniform distribution of slurry in both quantity and quality. The machine is ingeniously designed, relying on the weight of the slurry itself to rotate the inner container, thereby achieving uniform distribution. However, in existing technologies, different slurry compositions result in different conveying speeds within the rotating container, and the fixed discharge direction on the inner container leads to varying rotational speeds, resulting in inconsistent uniformity in the distribution of slurries with different compositions, thus affecting its applicability.

[0004] Therefore, a slurry distributor is needed that allows for adjustable discharge direction on the inner tank, making it suitable for slurries with different compositions. Utility Model Content

Detailed Implementation

[0019] like Figure 1-16 As shown, a slurry distributor in this embodiment includes a main body 1, with a plurality of circumferentially distributed discharge pipes 2 at the bottom of the main body 1, and a distribution mechanism 3 inside the main body 1, which is used to achieve uniform distribution of slurry. The main body 1 includes an outer barrel 11, a barrel cover 12, and a feed pipe 13. The barrel cover 12 is placed on the top of the outer barrel 11, the feed pipe 13 is vertically inserted through the barrel cover 12, and the discharge pipe 2 is located at the bottom of the outer barrel 11. A ladder 14 is provided on the outer wall of the outer barrel 11 for easy maintenance; The dispensing mechanism 3 includes an inner tub 31 and multiple dispensing pipes 32. The inner tub 31 is vertically arranged and has an opening at the top. The multiple dispensing pipes 32 are evenly distributed circumferentially around the vertical axis of the inner tub 31. The inner tub 31 is rotatably connected to the main body 1. Specifically, a rotating shaft 33 is provided at the bottom of the inner tub 31. The rotating shaft 33 is coaxially arranged with the inner tub 31 and rotatably passes through the outer tub 11. The inner tub 31 includes an upper tub body 311 and a lower tub body 312 distributed vertically, and the upper tub body 311 and the lower tub body 312 are detachably and fixedly connected by a flange 313. The distribution pipe 32 includes a connecting pipe section 321 and an adjusting pipe section 322. One end of the connecting pipe section 321 is horizontally fixed on the inner tub 31. Specifically, the connecting pipe section 321 is fixed on the lower tub 312. The axis of the connecting pipe section 321 is perpendicular to and intersects the axis of the inner tub 31. The adjusting pipe section 322 is detachably fixed on the other end of the connecting pipe section 321. The input end and output end of the adjusting pipe section 322 are distributed at 90 degrees. The regulating pipe section 322 includes a connecting part 3221 and a bending part 3222. The connecting part 3221 is tubular, and one end of the connecting part 3221 is detachably and fixedly connected to the connecting pipe section 321. The bending part 3222 is disposed at the other end of the connecting part 3221. The connecting part 3221 and the connecting pipe section 321 are arranged coaxially. The bending part 3222 is a quarter-circular ring. Multiple retaining strips 3223 are provided on the outer peripheral wall of the connecting pipe section 321. The multiple retaining strips 3223 are evenly distributed circumferentially around the connecting pipe section 321. The retaining strips 3223 are parallel to the connecting pipe section 321. Multiple retaining grooves 3224 are provided on the inner peripheral wall of the connecting part 3221. The multiple retaining grooves 3224 correspond one-to-one with the multiple retaining strips 3223 and are matched. The retaining strips 3223 are inserted into the retaining grooves 3224. The connecting pipe section 321 and the connecting part 3221 are locked together by a locking element, which is a locking screw. During operation, the slurry is conveyed from the feed pipe 13 to the inner barrel 31. The slurry in the inner barrel 31 is discharged sequentially from the connecting pipe section 321, the connecting part 3221 and the bending part 3222 to the outer barrel 11. The slurry in the outer barrel 11 is then discharged from the discharge pipe 2. When the slurry is discharged from the bending part 3222, a reverse thrust is generated, which causes the inner barrel 31 to drive the rotating shaft 33 to rotate on the main body 1, so as to make the slurry evenly distributed. Here, the two ends of the regulating pipe section 322 can be in the following situations; 1. When the regulating pipe section 322 is horizontally distributed, the inner barrel 31 rotates at its fastest speed. 2. Adjust the vertical distribution of both ends of the adjusting pipe section 322. At this time, the inner barrel 31 will stop rotating. 3. The two ends of the regulating pipe section 322 are inclined vertically. At this time, the inner barrel 31 rotates, and the rotation speed is lower than that of the regulating pipe section 322 when it is horizontally distributed. Here, the specific inclination angle can be 30 degrees and 60 degrees. When it is necessary to change the position of both ends of the adjusting pipe section 322, loosen the locking screw to separate the connecting pipe section 321 from the connecting part 3221. After rotating the connecting part 3221, the connecting part 3221 is reconnected to the connecting pipe section 321. At this time, the locking strip 3223 cooperates with the locking groove 3224 at different positions to adjust the angle of the adjusting pipe section 322, that is, to adjust the discharge direction on the inner barrel 31. The angle of the adjusting pipe section 322 can be rotated according to the different components of the slurry, so as to be suitable for different components of slurry. It also includes a cleaning mechanism 4, which is used to remove residual slurry inside the main body 1; The cleaning mechanism 4 includes a cleaning component 41 and a driving component 42. The cleaning component 41 is located inside the main body 1, and the driving component 42 is used to drive the cleaning component 41 to perform the action of removing residual slurry inside the main body 1. The cleaning assembly 41 includes a lifting ring 411, an electromagnet 412, and multiple scrapers 413. The multiple scrapers 413 correspond one-to-one with multiple distribution pipes 32. The lifting ring 411 is coaxially sleeved on the inner tub 31. The scrapers 413 are fixedly connected to the lifting ring 411. The electromagnet 412 and the lifting ring 411 are distributed vertically. The electromagnet 412 is fixedly connected to the inner tub 31. A guide rod 414 is vertically inserted through the lifting ring 411. The guide rod 414 is fixedly connected to the inner tub 31. A spring 415 is sleeved on the guide rod 414. The two ends of the spring 415 are respectively connected to the lifting ring 411 and the guide rod 414. When it is necessary to remove the residual slurry at the bottom of the main body 1, the lifting ring 411 is actually magnetic. When the electromagnet 412 is energized, the lifting ring 411 is lowered on the guide rod 414, which drives the scraper 413 to fall down and make the scraper 413 fit against the bottom of the main body 1. At the same time, the spring 415 is deformed. Then, the inner barrel 31 is rotated by the drive assembly 42. The rotation of the inner barrel 31 drives the scraper 413 to rotate inside the main body 1 through the guide rod 414 and the lifting ring 411. The scraper 413 pushes the residual slurry in the main body 1 to the discharge pipe 2 and discharges it. When it is necessary to remove the residual slurry on the inner wall of the main body 1, the electromagnet 412 is intermittently energized. When the electromagnet 412 is energized, the lifting ring 411 descends and the spring 415 deforms. The descent of the lifting ring 411 causes the scraper 413 to abut against the bottom of the main body 1. When the electromagnet 412 is de-energized, the lifting ring 411 rises under the elastic action of the spring 415 to reset. The reset of the lifting ring 411 causes the scraper 413 to reset. This process is repeated, causing the scraper 413 to intermittently strike the bottom of the main body 1, causing the main body 1 to vibrate, which facilitates the falling of the residual slurry on the inner wall of the main body 1 and its discharge from the discharge pipe 2. The drive assembly 42 includes a drive disc 421, a driven disc 422, a drive wheel 423, and a driven wheel 424. The driven wheel 424 is fixedly mounted on the outer peripheral wall of the inner tub 31. The axis of the drive disc 421 is horizontally arranged and located inside the main body 1. The drive disc 421 is located on one side of the driven wheel 424 and is driven by a motor 425. The driven disc 422 and the drive wheel 423 are both coaxially arranged with the drive disc 421. The driven disc 422 is located between the inner tub 31 and the drive disc 421, and the drive wheel 423 is located between the driven disc 422 and the inner tub 31. A plurality of transmission rods 426 are movably passed through the drive disk 421 and are fixedly connected to the driven disk 422. The transmission rods 426 are circumferentially distributed around the axis of the drive disk 421. The transmission rods 426 are parallel to the drive disk 421. One end of the transmission rod 426 is fixedly mounted on the driven disk 422. A moving ring 427 is coaxially sleeved on the driven disk 422. A cylinder 428 is connected to the moving ring 427. The cylinder 428 is used to drive the moving ring 427 to move along its own axis. An annular groove 429 is provided on the outer peripheral wall of the driven disk 422. The moving ring 427 is sleeved in the annular groove 429. When the motor 425 starts, it causes the drive disc 421 to rotate. The rotation of the drive disc 421 drives the driven disc 422 to rotate through the transmission rod 426. The rotation of the driven disc 422 drives the drive wheel 423 to rotate synchronously. When the inner tub 31 needs to rotate, the cylinder 428 drives the moving ring 427 to move closer to the inner tub 31. The movement of the moving ring 427 drives the driven disc 422 to move, and makes the drive wheel 423 contact the driven wheel 424. The rotation of the drive wheel 423 drives the driven wheel 424 to rotate, thus realizing the rotation of the inner tub 31. When the cylinder 428 drives the moving ring 427 to move in the opposite direction to achieve a reset, the drive wheel 423 and the driven wheel 424 are separated, and the inner tub 31 stops rotating. During the rotation of the driven disc 422, the moving ring 427 and the driven disc 422 rotate relative to each other. Here, both the driving wheel 423 and the driven wheel 424 can be bevel gears. When the inner barrel 31 needs to rotate, the driving wheel 423 meshes with the driven wheel 424. Both the driving wheel 423 and the driven wheel 424 can also be friction wheels. When the driving wheel 423 contacts the driven wheel 424, the driving wheel 423 drives the driven wheel 424 to rotate through the friction force. In summary, by adjusting the discharge angle of the distribution pipe 32, i.e., adjusting the discharge direction on the inner barrel 31, the angle of the pipe section 322 can be adjusted according to the different components of the slurry. This makes it easy to adapt to slurries of different components. In addition, the rotation of the scraper 413 at the bottom of the main body 1 makes it easy to remove the slurry remaining at the bottom of the main body 1. Moreover, by intermittently tapping the bottom of the main body 1 with the scraper 413, the main body 1 vibrates, making it easy for the slurry remaining on the inner wall of the main body 1 to fall off and be discharged from the discharge pipe 2.
