Description

Technical Field

[0001] This invention relates to the field of variable displacement pump technology, specifically to a graded feeding pump for polyester titanium dioxide slurry. Background Technology

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

[0003] However, in existing polyester titanium dioxide slurry classifying and feeding pumps, the inlet and outlet of the pump body are fixed. The piston reciprocates within the pump body, alternately drawing in and discharging the slurry. This causes the slurry to move with the piston within the pump body, resulting in a large stroke and easy wear on the inner wall of the pump body. Furthermore, the slurry tends to accumulate on the inner wall of the pump body, making cleaning difficult and affecting its performance and lifespan. The inner wall of the pump body may develop raised defects due to slurry deposits, scale buildup, wear corrosion, or mechanical damage, which are difficult to detect in time and also affect its performance, lifespan, and conveying efficiency. During the conveying process, titanium dioxide slurry may agglomerate or clump, or impurities may be introduced into the slurry, potentially causing blockages in the inlet and outlet pipes of the piston pump. Blockages reduce the pump's conveying capacity, affecting its efficiency and effectiveness. Summary of the Invention

Each piston pump module includes a base 101, a pump body 102, a piston rod 107, a piston 104, and a hydraulic oil pipe 103. The base 101, pump body 102, piston rod 107, piston 104, and hydraulic oil pipe 103 are well-known technologies in this field and will not be described in detail here. Each piston pump module also includes:

[0043] The first delivery pipe 105 is connected to the pump body 102 through two first L-shaped pipes 11;

[0044] The second delivery pipe 106 is connected to the pump body 102 through two second L-shaped pipes 12;

[0045] The feed pipe 13 is fixedly inserted into the end of the piston 104 and is connected to the first L-shaped pipe 11 through the first telescopic pipe 15;

[0046] The discharge pipe 14 is fixedly inserted into the end of the piston 104 and is connected to the second L-shaped pipe 12 through the second telescopic pipe 16;

[0047] The first cleaning mechanism is located at the end of the piston 104 and is used to clean the inner wall of the pump body 102.

[0048] The detection mechanism, located at the end of the piston 104, is used to detect protrusion defects on the inner wall of the pump body 102. During the extraction and extrusion of polyester titanium dioxide slurry, the feed pipe 13 and the discharge pipe 14 can move synchronously with the piston 104, which can reduce the movement of the slurry within the pump body 102, reduce wear on the inner wall of the pump body 102, and automatically scrape and clean the inner wall of the pump body 102, making it more convenient and faster, and ensuring its performance and lifespan. It facilitates the detection of protrusion defects on the inner wall of the pump body 102, ensuring its performance and lifespan. It can clean the inner walls of the first L-shaped tube 11 and the second L-shaped tube 12, and at the same time, it can create a shaking effect on the first telescopic tube 15 and the second telescopic tube 16, preventing polyester titanium dioxide slurry from adhering to the inner walls of the first telescopic tube 15 and the second telescopic tube 16, avoiding blockage, and ensuring the efficiency and effect of feeding.

An annular groove 205 is formed at the end of the pump body 102. A moving ring 206 is connected to the annular groove 205 via a telescopic mechanism. Multiple arrayed rectangular grooves 207 are formed on the side wall of the annular groove 205. A stop block 208 is inserted into each rectangular groove 207, and the stop block 208 is fixedly connected to the moving ring 206. The rotation of the rotating ring 203 is driven by a drive mechanism. When the rotating ring 203 rotates, the rubber plate 204 can automatically scrape and clean the inner wall of the pump body 102, which is more convenient and faster, and ensures its effectiveness and lifespan. When the rubber plate 204 abuts against the stop block 208, it can push the stop block 208 to slide into the rectangular groove 207 and the moving ring 206 to slide 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 housed in the rectangular groove 207 and the annular groove 205, ensuring that the piston 104 can abut against the end of the pump body 102, ensuring the discharge effect.

[0050] Please see Figure 10 The telescopic mechanism includes a fixed tube 301 fixedly connected to the end of the annular groove 205, and a second moving rod 302 is inserted into the fixed tube 301. The other end of the second moving rod 302 is fixed to the end of the moving ring 206. A first spring 303 is sleeved on the side wall of each fixed tube 301, which guides and resets the movement of the moving ring 206.

[0051] Please see Figure 11 and Figure 15The detection mechanism includes a first fixing block 501 fixedly connected to the side wall of the pump body 102, and a pointer 503 rotatably connected to the top of the first fixing block 501 via a first rotating shaft 502.

The second push pin 518 is inserted into the slide groove 517. When the piston 104 moves towards the moving ring 206, the rubber plate 204 can scrape and clean the inner wall of the pump body 102. When a protrusion 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 moving rod 201. At the same time, it can drive the moving block 509 to move synchronously, so that the first push pin 512 can slide along the inclined groove 510, thereby pushing the moving block 509 towards the... The pump body 102 moves towards the second fixed block 506 and pushes the first T-shaped guide rod 514 to move synchronously. The second spring 515 is compressed. 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, and thus determine whether there is a protrusion defect on the inner wall of the pump body 102. This facilitates the detection of protrusion defects on the inner wall of the pump body 102, ensuring its performance and lifespan.

[0052] Please see Figure 12The driving mechanism includes a mounting groove 401 at the end of the piston 104, and a rubber wheel 402 is inserted into the mounting groove 401. The rubber wheel 402 can abut against the inner sidewall of the rotating ring 203, so that the rotating ring 203 can rotate when the rubber wheel 402 rotates. A guide rod 403 is fixedly connected to the end of the rubber wheel 402, and the other end of the guide rod 403 passes through the end of the piston 104 and is fixedly connected to a first driven bevel gear 406. A third spring 404 is sleeved on the sidewall of the guide rod 403. One end of the third spring 404 is fixed to the rubber wheel 402, and the other end of the third spring 404 is rotatably connected to the end of the mounting groove 401. Two first sleeves 410 are fixedly connected to the end of the piston 104. A first sleeve rod 411 is inserted into each first sleeve 410, and the other end of the first sleeve rod 411 is fixedly connected to a mounting box 405.

The guide rod 403 is rotatably connected to the side wall of the mounting box 405, and the top of the mounting box 405 is rotatably connected to a rubber disc 409 via a second rotating shaft 407. The lower end of the second rotating shaft 407 is fixedly connected to a first driving bevel gear 408, which meshes with a first driven bevel gear 406. 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 driving bevel gear 408 to rotate via the second rotating shaft 407, thereby driving the rubber wheel 402 to rotate via 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. When the rubber wheel 402 abuts against the end of the pump body 102, the rubber wheel 402 can retract into the mounting groove 401, and at the same time, the third spring 404 is compressed.

Multiple arrayed rubber protrusions 606 are fixedly connected to the top and bottom of the rubber disc 409. A first push rod 605 is fixedly connected to the bottom of the collar 601. The end of the first push rod 605 away from the collar 601 can slide on the side wall of the rubber protrusion 606. When the rubber disc 409 rotates, when the end of the first push rod 605 abuts against the rubber protrusion 606, it can push the collar 601 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 the rubber protrusion 606, the collar 601 can move back to its original position under the action of the fourth spring. By repeating this process, the collar 601 can move up and down, which can have a shaking effect on the first telescopic tube 15 and the second telescopic tube 16, preventing the polyester titanium dioxide slurry from adhering to the inner wall of the first telescopic tube 15 and the second telescopic tube 16, and ensuring the efficiency and effect of feeding.

When the drive shaft 705 rotates, it drives the second driving bevel gear 706 to rotate, thereby driving the rotating rod 702 to reciprocate 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 faster, avoids blockage, and ensures the efficiency and effect of feeding.

A mounting block 812 is fixedly connected to the top of the rack 804. A U-shaped plate 806 is fixedly connected to the side wall of the mounting block 812. A second push rod 807 is fixedly connected to the side wall of the U-shaped plate 806. A fixing box 808 is fixedly inserted into the side wall of the hydraulic oil pipe 103. A rotating fan 810 is rotatably connected to the fixing box 808 via a power shaft 809. A cam 811 is fixedly connected to the lower end of the power shaft 809. The end of rod 807 away from U-shaped plate 806 can slide on the side wall of cam 811. When hydraulic oil enters hydraulic oil pipe 103, it can enter fixed box 808 and impact the side wall of rotating fan 810, causing it to rotate. When rotating fan 810 rotates, it can drive cam 811 to rotate through power shaft 809. When the tip of cam 811 abuts against the end of second push rod 807, it can push U-shaped plate 806 to move. At the same time, it drives rack 804 to move through mounting block 812. Fifth spring 805 is compressed. When the tip of cam 811 passes the end of second push rod 807, rack 804 can move and reset under the action of fifth spring 805. This reciprocating motion can make rack 804 move back and forth, thereby driving gear 801 to rotate back and forth. When gear 801 rotates, it can rotate through drive shaft 705.

[0056] Please see Figure 14A first one-way mechanism is provided inside the feed pipe 13. The first one-way mechanism includes a first perforated plate 901 fixedly connected to the inner side wall of the feed pipe 13, and two second T-shaped guide rods 902 are inserted into the side wall of the first perforated plate 901. One end of the second T-shaped guide rod 902 is fixedly connected to a second perforated disk 903. The perforated holes on the first perforated plate 901 and the second perforated disk 903 are staggered. A sixth spring 904 is sleeved on the side wall of each second T-shaped guide rod 902, and a first telescopic cover 905 is sleeved on the side wall of the sixth spring 904. When the piston 104 moves away from the piston, the mechanism is activated. When the moving ring 206 moves in a certain direction, it creates a negative pressure inside the pump body 102. At this time, the second perforated disc 903 moves away from the first perforated plate 901, and the sixth spring 904 is compressed. At this time, the first one-way mechanism opens, and the polyester titanium dioxide slurry can enter the pump body 102 through the first perforated plate 901 and the second perforated disc 903. When the piston 104 moves towards the moving ring 206, it squeezes the slurry inside the pump body 102, causing the second perforated disc 903 to abut and seal against the first perforated plate 901. At this time, the first one-way mechanism closes.

[0057] Please see Figure 13 The discharge pipe 14 is equipped with a second one-way mechanism, which includes a third hollowed-out disc 1001 fixedly connected to the inner wall of the discharge pipe 14. Two symmetrically arranged third T-shaped guide rods 1002 are fixedly connected to the ends of the third hollowed-out disc 1001. A fourth hollowed-out disc 1003 is sleeved on the side wall of each third T-shaped guide rod 1002. The hollowed-out holes on the third hollowed-out disc 1001 and the fourth hollowed-out disc 1003 are staggered. A seventh spring 1004 is sleeved on the side wall of each third T-shaped guide rod 1002, and a second telescopic cover 100 is sleeved on the side wall of the seventh spring 1004. 5. When the piston 104 moves away from the moving ring 206, a negative pressure is generated inside the pump body 102. At this time, the fourth hollowed-out plate 1003 and the third hollowed-out plate 1001 abut and seal. At this time, the second one-way mechanism is closed. When the piston 104 moves closer to the moving ring 206, it squeezes the slurry inside the pump body 102, causing the fourth hollowed-out plate 1003 to move away from the third hollowed-out plate 1001. At the same time, the seventh spring 1004 is compressed. At this time, the second one-way mechanism is opened, allowing the slurry inside the pump body 102 to be discharged through the discharge pipe 14.

[0058] Working principle: During use, hydraulic oil is supplied to the pump body 102 through the hydraulic oil pipe 103. This allows the piston rod 107 to drive the piston 104 to reciprocate within the pump body 102. When the piston 104 moves away from the moving ring 206, a negative pressure is generated within the pump body 102. Simultaneously, the first one-way mechanism opens and the second one-way mechanism closes. At this time, the polyester titanium dioxide slurry can gradually enter the pump body 102 through the first conveying 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, a negative pressure is generated within the pump body 102. When the piston 104 moves toward the moving ring 206, it can squeeze the polyester titanium dioxide slurry in the pump body 102. At the same time, the first one-way mechanism closes and the second one-way mechanism opens. At this time, it can be discharged through the discharge pipe 14, the second telescopic pipe 16 and the second L-shaped pipe 12. Thus, 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 performance and service life.

[0059] Meanwhile, 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 driving 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 rubber plate 204 can rotate the pump body. The inner wall of 102 is automatically scraped and cleaned, which is more convenient and faster, and ensures its effectiveness and lifespan. When the rubber plate 204 abuts against the stop block 208, it can push the stop block 208 to slide into the rectangular groove 207 and the moving ring 206 to slide 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 stored in the rectangular groove 207 and the annular groove 205, ensuring that the piston 104 can abut against the end of the pump body 102, ensuring the discharge effect.

[0060] When the piston 104 moves closer to the moving ring 206, the rubber plate 204 can scrape and clean the inner wall of the pump body 102. When a protrusion 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 stops moving. When the piston 104 continues to move, the piston 104 can slide along the side wall of the first moving rod 201. At the same time, it can drive the moving block 509 to move synchronously, so that the first push pin 512 can slide along the inclined groove 510, thereby pushing the moving block 509 to move closer to the second fixed block 506. The first T-shaped guide rod 514 is pushed to move synchronously, and the second spring 515 is compressed. 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, and thus determine whether there is a protrusion defect on the inner wall of the pump body 102. This facilitates the detection of protrusion defects on the inner wall of the pump body 102, ensuring its performance and lifespan.

[0061] When hydraulic oil enters the hydraulic oil pipe 103, it can enter the fixed box 808 and impact the side wall of the rotating fan 810, causing it to rotate. When the rotating fan 810 rotates, it can drive the cam 811 to rotate via the power shaft 809. When the tip of the cam 811 abuts against the end of the second push rod 807, it can push the U-shaped plate 806 to move. At the same time, it drives the rack 804 to move via the mounting block 812, and the fifth spring 805 is compressed. When the tip of the cam 811 passes the end of the second push rod 807, the rack 804 can... The rack 804 moves back and forth under the action of the fifth spring 805. This reciprocating motion causes the rack 804 to move back and forth, which in turn drives the gear 801 to rotate back and forth. When the gear 801 rotates, it drives the second driving bevel gear 706 to rotate through the drive shaft 705. This drives 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 faster, avoids blockage, and ensures the efficiency and effect of feeding.

[0062] When the rubber disc 409 rotates, when the end of the first push rod 605 abuts against the rubber protrusion 606, it can push the collar 601 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 the rubber protrusion 606, the collar 601 can move back to its original position under the action of the fourth spring. By repeating this process, the collar 601 can move up and down, which can have a shaking effect on the first telescopic tube 15 and the second telescopic tube 16, preventing the polyester titanium dioxide slurry from adhering to the inner wall of the first telescopic tube 15 and the second telescopic tube 16, and ensuring the efficiency and effect of feeding.
