Description

Technical Field

[0001] The invention relates to the technical field of variable displacement pumps, in particular to a polyester titanium dioxide slurry graded feeding pump. Background Art

[0002] During the production of polyester titanium dioxide slurry, a graded feeding pump is required for transportation. If the transportation distance is long or the pipeline resistance is large, multiple pumps in series (such as centrifugal pumps in series) may be used to superimpose pressure to achieve "graded" pressurization to avoid interruption of transportation due to insufficient pressure of a single pump. The piston pump is a positive displacement pump that relies on the reciprocating motion of the piston in the pump body to cause the volume of several working chambers in the pump body to change periodically, thereby alternately sucking in and discharging liquid, and converting the mechanical energy of the reciprocating motion of the piston into liquid pressure energy. It is a type of liquid variable displacement pump, and the piston is driven to reciprocate in the pump body by a hydraulic module.

[0003] However, when the existing polyester titanium dioxide slurry grading feeding pump is in use, the feed port and the discharge port of the pump body are fixedly arranged on the pump body, and the piston reciprocates in the pump body to alternately suck in and discharge the slurry, so that the slurry moves with the piston in the pump body, resulting in a large movement stroke of the slurry in the pump body, which is easy to cause wear of the inner wall of the pump body. At the same time, the slurry is easy to accumulate on the inner wall of the pump body, which is inconvenient to clean, affecting its use effect and life; the inner wall of the pump body may produce convex defects due to slurry deposition and scaling, wear and corrosion or mechanical damage, which is not easy to be discovered in time, and will also affect its use effect and life, as well as the conveying effect; during the conveying process, the titanium dioxide slurry may agglomerate or clump, or impurities may be mixed into the slurry, which may cause the inlet and outlet pipes of the piston pump to be blocked. The blockage will reduce the conveying capacity of the pump, affecting the efficiency and effect of the conveying. Summary of the Invention

When the tip of the cam 811 abuts against the end of the second push rod 807, the U-shaped plate 806 can be pushed to move. At the same time, the rack 804 is driven to move through the mounting block 812, and the fifth spring 805 is compressed. When the tip of the cam 811 passes over the end of the second push rod 807, the rack 804 can move and reset under the action of the fifth spring 805. This reciprocating process can make the rack 804 move back and forth, thereby driving the gear 801 to rotate back and forth. When the gear 801 rotates, it can be rotated through the drive shaft 705.

The side walls of each second T-shaped guide rod 902 are sleeved with a sixth spring 904, and the side walls of the sixth spring 904 are sleeved with a first telescopic cover 905. When the piston 104 moves away When the movable ring 206 moves in the direction of the movable ring 206, negative pressure is generated in the pump body 102. At this time, the second hollow disk 903 moves away from the first hollow plate 901. At the same time, the sixth spring 904 is compressed. At this time, the first one-way mechanism is opened, and the polyester titanium dioxide slurry can enter the pump body 102 through the first hollow plate 901 and the second hollow disk 903. When the piston 104 moves in the direction close to the movable ring 206, the slurry in the pump body 102 is squeezed, so that the second hollow disk 903 and the first hollow plate 901 are sealed against each other. At this time, the first one-way mechanism is closed.

[0044] See also Figure 13 , a second one-way mechanism is provided in the discharge pipe 14, and the second one-way mechanism includes a third hollow disk 1001 fixedly connected to the inner wall of the discharge pipe 14, and the end of the third hollow disk 1001 is fixedly connected to two symmetrically arranged third T-shaped guide rods 1002, and the side wall of the third T-shaped guide rod 1002 is provided with a fourth hollow disk 1003, and the hollow holes on the third hollow disk 1001 and the fourth hollow disk 1003 are staggered with each other, and the side wall of each third T-shaped guide rod 1002 is provided with a seventh spring 1004, and the side wall of the seventh spring 1004 is provided with a second telescopic cover 100 5. When the piston 104 moves in the direction away from the movable ring 206, negative pressure is generated in the pump body 102. At this time, the fourth hollow disk 1003 and the third hollow disk 1001 are sealed against each other. At this time, the second one-way mechanism is closed. When the piston 104 moves in the direction close to the movable ring 206, the slurry in the pump body 102 is squeezed, so that the fourth hollow disk 1003 moves in the direction away from the third hollow disk 1001. At the same time, the seventh spring 1004 is compressed. At this time, the second one-way mechanism is opened, so that the slurry in the pump body 102 can be discharged through the discharge pipe 14.

[0045] Working principle: When in use, hydraulic oil is supplied to the pump body 102 through the hydraulic oil pipe 103, and the piston 104 can be driven to move back and forth in the pump body 102 through the piston rod 107. When the piston 104 moves away from the moving ring 206, negative pressure is generated in the pump body 102. At the same time, the first one-way mechanism is opened and the second one-way mechanism is closed. At this time, the polyester titanium dioxide slurry can gradually enter the pump body 102 through the first delivery pipe 105, the first L-shaped pipe 11, the first telescopic pipe 15 and the feed pipe 13. Similarly, when the piston 104 moves away from the moving ring 206, negative pressure is generated in the pump body 102. At the same time, the first one-way mechanism is opened and the second one-way mechanism is closed. At this time, the polyester titanium dioxide slurry can gradually enter the pump body 102 through the first delivery pipe 105, the first L-shaped pipe 11, the first telescopic pipe 15 and the feed pipe 13. When the plug 104 moves toward the direction close to the movable ring 206, it can squeeze the polyester titanium dioxide slurry in the pump body 102. At the same time, the first one-way mechanism is closed and the second one-way mechanism is opened. At this time, it can be discharged through the discharge pipe 14, the second telescopic tube 16 and the second L-shaped tube 12, so that during extraction and extrusion, the feed pipe 13 and the discharge pipe 14 can move synchronously with the piston 104, which can reduce the movement stroke of the slurry in the pump body 102, reduce the wear on the inner wall of the pump body 102, and ensure its use effect and life.

[0046] At the same time, when the piston 104 moves, the rubber disc 409 can roll on the inner wall of the pump body 102, causing the rubber disc 409 to rotate. When the rubber disc 409 rotates, it can drive the first active bevel gear 408 to rotate through the second rotating shaft 407, thereby driving the rubber wheel 402 to rotate through the first driven bevel gear 406 and the guide rod 403. When the rubber wheel 402 rotates, it can drive the rotating ring 203 to rotate. At this time, the pump body can be rotated through the rubber plate 204. The inner wall of 102 is automatically scraped and cleaned, which is more convenient and quick, and ensures its use effect and life. When the rubber plate 204 is against the block 208, the block 208 can be pushed to slide into the rectangular groove 207, and the movable ring 206 slides into the annular groove 205. At the same time, the first spring 303 is compressed. At this time, the rubber plate 204 and the rotating ring 203 can be accommodated in the rectangular groove 207 and the annular groove 205, ensuring that the piston 104 can be against the end of the pump body 102, thereby ensuring the discharge effect.

[0047] When the piston 104 moves toward the direction close to the movable ring 206, the rubber plate 204 can scrape and clean the inner wall of the pump body 102. When a convex defect appears on the inner wall of the pump body 102, it can abut against the end of the rotating ring 203. At this time, the rotating ring 203 no longer moves. When the piston 104 continues to move, the piston 104 can slide along the side wall of the first movable rod 201. At the same time, it can drive the movable block 509 to move synchronously, so that the first push pin 512 can slide along the inclined groove 510, thereby pushing the movable block 509 to move toward the direction close to the second fixed block 506. , and pushes the first T-shaped guide rod 514 to move synchronously, the second spring 515 is compressed, and when the first T-shaped guide rod 514 moves, it can drive the second push pin 518 to slide in the slide groove 517 through the first connecting block 516, thereby pushing the pointer 503 to rotate along the first rotating shaft 502. At this time, the visual sensor 505 can detect the scale on the dial 504 indicated by the pointer 503 to determine whether there is a convex defect on the inner wall of the pump body 102, thereby facilitating the detection of the convex defect on the inner wall of the pump body 102 and ensuring its use effect and life.

[0048] When the hydraulic oil enters the hydraulic oil pipe 103, it can enter the fixed box 808 and impact the side wall of the rotary fan 810, causing it to rotate. When the rotary fan 810 rotates, the cam 811 can be driven to rotate by the power shaft 809. When the tip of the cam 811 abuts against the end of the second push rod 807, the U-shaped plate 806 can be pushed to move. At the same time, the rack 804 is driven to move by the mounting block 812, and the fifth spring 805 is compressed. When the tip of the cam 811 passes over the end of the second push rod 807, the rack 804 can Under the action of the fifth spring 805, it moves and resets, and so on, the rack 804 can move back and forth, thereby driving the gear 801 to rotate back and forth. When the gear 801 rotates, the second active bevel gear 706 can be driven to rotate through the drive shaft 705, thereby driving the rotating rod 702 to rotate back and forth through the second driven bevel gear 703. At this time, the cleaning rod 704 can be used to clean the inner walls of the first L-shaped tube 11 and the second L-shaped tube 12, which is more convenient and quick, avoids blockage, and ensures the efficiency and effect of feeding.

[0049] When the rubber disc 409 rotates, when the end of the first push rod 605 abuts against the rubber protrusion 606, the ring 601 can be pushed to move away from the connecting plate 604. At the same time, the fourth spring is stretched. When the end of the first push rod 605 passes over the rubber protrusion 606, the ring 601 can move and reset under the action of the fourth spring. This reciprocating motion can make the ring 601 move up and down, which can have a shaking effect on the first telescopic tube 15 and the second telescopic tube 16, thereby preventing the polyester titanium dioxide slurry from adhering to the inner walls of the first telescopic tube 15 and the second telescopic tube 16, and ensuring the efficiency and effect of feeding.
