Description

Technical Field

[0001] The present invention relates to the technical field of sediment removal, and in particular to an automatic quantitative sediment removal system. Background Art

[0002] After a cold rolling mill has been operating for a period of time and rolling a certain amount of steel, its roll surfaces wear, resulting in plate quality defects. To ensure the surface quality of the strip, roll replacement is necessary according to process requirements. During roll replacement, the flat head of the work roll shaft must be withdrawn from the flat head sleeve, and the new work roll is then pushed into the main coupling shaft head, completing the roll change. Traditionally, roll replacement has been done manually, which takes a long time. The old work roll is difficult to push out and the new work roll is difficult to pull into place. The entire roll replacement process is time-consuming, reducing production efficiency. Summary of the Invention

[0037] In order to make the purpose, technical solutions and advantages of this application more clearly understood, the present application is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0038] Example 1

[0039] Combine Figures 1 to 6 As shown, an embodiment of the present invention discloses an automatic quantitative sand removal system, a sand discharge mechanism and a controller, wherein the sand discharge mechanism includes a sand storage bin 7, a first ball valve 8, a second ball valve 9, and a drive motor 13, and the drive motor 13 is a self-locking motor; the first ball valve 8 is installed on the pipe at the upper end of the sand storage bin 7; the second ball valve 9 is installed at the bottom of the sand storage bin 7; the drive motor 13 is transmission-connected to the first ball valve 8 and the second ball valve 9.

[0040] The controller of this embodiment is electrically connected to the drive motor 13 and includes two laser lamps 19, two optical signal boards, and a control circuit. One laser lamp 19 is positioned on the pipe between the upper port of the sand storage bin 7 and the first ball valve 8, while the other laser lamp 19 is positioned on the pipe between the lower port of the sand storage bin 7 and the second ball valve 9. Light emitted by the laser lamp 19 penetrates the pipe. The two optical signal boards are positioned opposite the two laser lamps 19, respectively. It is worth noting that in actual use, due to installation space limitations, an optical fiber tube can be installed between the laser lamps 19 and the optical signal board. This conducts light from the laser lamp 19 to the optical signal board.

[0041] The control circuit of this embodiment is electrically connected to the laser lamp 19, the optical signal board and the drive motor 13; when the two laser lamps 19 both illuminate the corresponding optical signal board, it means that the mud and sand in the sand storage bin 7 are completely discharged. At this time, the control circuit controls the drive motor 13 to drive the first ball valve 8 to open and the second ball valve 9 to close, and sand is stored in the sand storage bin 7; when the two laser lamps 19 cannot illuminate the corresponding optical signal board, it means that the mud and sand in the sand storage bin 7 are completely filled. The control circuit controls the drive motor 13 to drive the first ball valve 8 to close and the second ball valve 9 to open, and discharge the stored sand.

[0042] Furthermore, the sand removal mechanism of this embodiment also includes a first transmission gear 14, a second transmission gear 15, a third transmission gear 16, a rack 17, and a support 18. The support 18 is fixed, and the rack 17 is slidably mounted on the support 18. The support 18 ensures stable and smooth sliding of the rack 17. The first transmission gear 14 is mounted on the rotating shaft of the drive motor 13 and meshes with the rack 17. The second transmission gear 15 is mounted on the rotating rod of the first ball valve 8, and the third transmission gear 16 is mounted on the rotating rod of the second ball valve 9. The first, second, and third transmission gears 14, 15, 16 all mesh with the rack 17. The axes of the valve ports of the first and second ball valves 8, 9 are arranged perpendicularly. When the first transmission gear 14 rotates, it drives the rack 17 to translate, which in turn drives the second and third transmission gears 15, 16 to rotate, thereby driving the rotation of the first and second ball valves 8, 9, and changing the on / off state of the first and second ball valves 8, 9.

[0043] The power supply 21 of the control circuit is connected in series with a master control switch 36 for controlling the on and off of the entire circuit, which is convenient for operation and maintenance.

[0044] Furthermore, the control circuit of this embodiment includes a power supply 21, a master control switch 36, a first double-control switch 22, a second double-control switch 23, a first electromagnet 24, a second electromagnet 25, a third electromagnet 26, a fourth electromagnet 27, a first normally closed switch 28, a first normally open switch 29, a first control electromagnet 30, and a second control electromagnet 31. The power supply 21 is connected in series with the master control switch 36 to control the on / off of the entire circuit, facilitating operation and maintenance. Furthermore, the power supply 21, the first normally closed switch 28, the third electromagnet 26, and the fourth electromagnet 27 are connected in series; the power supply 21, the first normally open switch 29, the first electromagnet 24, and the second electromagnet 25 are connected in series; the power supply 21, the first contact of the first double-control switch 22, the first contact of the second double-control switch 23, and the drive motor 13 are connected in series; the power supply 21, the second contact of the first double-control switch 22, the second contact of the second double-control switch 23, and the drive motor 13 are connected in series.

[0045] It is worth noting that the optical signal board in this embodiment is a photoelectric board 20. One photoelectric board 20 is connected in series with a first control electromagnet 30, and the first control electromagnet 30 is arranged opposite to the first normally closed switch 28. When the first control electromagnet 30 is energized, the first normally closed switch 28 is opened; the other photoelectric board 20 is connected in series with a second control electromagnet 31, and the second control electromagnet 31 is arranged opposite to the first normally open switch 29. When the second control electromagnet 31 is energized, the first normally open switch 29 is closed.

[0046] Furthermore, the control circuit also includes a second normally closed switch 32 and a third normally closed switch 33; the second normally closed switch 32 is connected in series with the power supply 21, the first contact of the first double-control switch 22, the first contact of the second double-control switch 23, and the drive motor 13; the third normally closed switch 33 is connected in series with the power supply 21, the second contact of the first double-control switch 22, the second contact of the second double-control switch 23, and the drive motor 13; correspondingly, both ends of the rack 17 of this embodiment are connected with insulating pressure rods 34. When the drive motor 13 drives the rack 17 to move to the first ball valve 8 to open and the second ball valve 9 to close, the insulating pressure rod 34 at the upper end of the rack 17 abuts against the second normally closed switch 32 to disconnect the second normally closed switch 32; when the drive motor 13 drives the rack 17 to move to the first ball valve 8 to close and the second ball valve 9 to open, the insulating pressure rod 34 at the lower end of the rack 17 abuts against the third normally closed switch 33 to disconnect the third normally closed switch 33.

[0047] Furthermore, the levers of the first and second dual-control switches 22 and 23 are both arranged vertically. When the levers are connected to the contacts, the levers are tilted. The first and third electromagnets 24 and 26 are mounted on either side of the first dual-control switch 22, respectively; the second and fourth electromagnets 25 and 27 are mounted on either side of the second dual-control switch 23, respectively.

[0048] The control principle of quantitative cleaning in this embodiment is:

[0049] When the sediment in the sand storage bin 7 is reduced to the bottom of the sand storage bin 7, the two laser lights 19 are irradiated to the corresponding optical signal board, and the two photoelectric panels 20 are both generating electricity. The first control electromagnet 30 and the second control electromagnet 31 are both generating magnetic force, so that the first normally closed switch 28 is disconnected and the first normally open switch 29 is closed. At this time, the circuit in which the power supply 21, the first normally closed switch 28, the third electromagnet 26 and the fourth electromagnet 27 are connected in series has no electricity; and the circuit in which the power supply 21, the first normally open switch 29, the first electromagnet 24 and the second electromagnet 25 are connected in series is electrically conductive, and the first electromagnet 24 and the second electromagnet 25 are electrically conductive. The iron 25 respectively absorbs the levers of the first double-control switch 22 and the second double-control switch 23 and is respectively placed on the first contact of the first double-control switch 22 and the first contact of the second double-control switch 23; thereby, the circuit in which the power supply 21, the first contact of the first double-control switch 22, the first contact of the second double-control switch 23, the drive motor 13, and the second normally closed switch 32 are connected in series is energized, and the drive motor 13 rotates forward to drive the rack 17 to move. After running for a period of time, the first ball valve 8 will gradually open to the maximum, and the second ball valve 9 will gradually close completely, and the flowing sediment in the sedimentation tank will flow into the sand storage bin 7.

[0050] When a certain amount of mud and sand is added, causing the laser light 19 below to be unable to illuminate the photoelectric panel 20, the second control electromagnet 31 loses power, causing the first normally open switch 29 to be disconnected. The circuit connected in series by the power supply 21, the first normally open switch 29, the first electromagnet 24, and the second electromagnet 25 loses power and is disconnected. The first electromagnet 24 and the second electromagnet 25 lose their attraction to the levers of the first double-control switch 22 and the second double-control switch 23. However, since the lever is tilted when connected to the contact, the lever still maintains contact with the contact under the action of its own weight. Then, the circuit in series of the power supply 21, the first contact of the first double-control switch 22, the first contact of the second double-control switch 23, the drive motor 13, and the second normally closed switch 32 remains in an electrically conductive state, and the drive motor 13 rotates forward to drive the rack 17 to continue moving until the first valve is opened to the maximum and the second valve is completely closed. At this time, the insulating pressure rod 34 connected to the upper end of the rack 17 abuts against the second normally closed switch 32 to disconnect the second normally closed switch 32, thereby disconnecting the circuit in series of the power supply 21, the first contact of the first double-control switch 22, the first contact of the second double-control switch 23, the drive motor 13, and the second normally closed switch 32. The drive motor 13 stops rotating and locks, the first ball valve 8 is fully opened, and the second ball valve 9 is fully closed.

[0051] When a certain amount of sediment continues to be added, causing the laser light 19 above to illuminate the photoelectric panel 20, the first control electromagnet 30 loses power, causing the first normally closed switch 28 to close. At this time, the circuit connected in series by the power supply 21, the first normally closed switch 28, the third electromagnet 26, and the fourth electromagnet 27 is closed. The third electromagnet 26 and the fourth electromagnet 27 respectively attract the levers of the first double-control switch 22 and the second double-control switch 23 and place them on the second contacts of the first double-control switch 22 and the second double-control switch 23, respectively. As a result, the circuit connected in series by the power supply 21, the second contacts of the first double-control switch 22 and the second contacts of the second double-control switch 23, the drive motor 13, and the third normally closed switch 33 is energized and connected. The drive motor 13 rotates in the opposite direction to drive the rack 17 to move. After a period of operation, the first ball valve 8 gradually closes completely, and the second ball valve 9 gradually opens to its maximum. The mobile sediment in the sedimentation tank stops flowing into the sand storage bin 7, and the sediment in the sand storage bin 7 begins to be discharged.

[0052] At this time, when the insulating pressure rod 34 connected to the lower end of the rack 17 abuts against the third normally closed switch 33 to disconnect the third normally closed switch 33, the circuit in series of the power supply 21, the second contact of the first double-control switch 22, the second contact of the second double-control switch 23, the drive motor 13, and the third normally closed switch 33 will be disconnected and de-energized, the drive motor 13 will stop rotating and lock, and the rack 17 will move into place.

[0053] Then, when the sediment in the sand storage bin 7 is reduced to the bottom of the sand storage bin 7 again so that both laser lamps 19 illuminate the corresponding light signal board, feeding will start again, and this cycle will be repeated to ensure the continuous feeding of sediment.

[0054] Furthermore, the automatic quantitative sedimentation and discharge system of the present embodiment also includes a sedimentation tank, which includes a plurality of tank bodies 1 and a plurality of conveying channels 2; each tank body 1 includes a short arc-shaped tank wall 4, a long arc-shaped tank wall 5 and a conical tank bottom wall 6; the bottom of the conical tank bottom wall 6 is connected to the upper end of the first ball valve 8. It is worth noting that the diameters of the plurality of tank bodies 1 of the present embodiment increase successively along the direction of water flow, which can better adapt to changes in water flow and the sediment deposition process, and improve sedimentation efficiency. This design causes the flow rate of water to gradually slow down when passing through each tank body 1, which is conducive to better sedimentation of sediment. As the diameter of the tank body 1 increases, the cross-sectional area of the water flow increases. According to the principles of fluid mechanics, the flow rate will decrease accordingly, making it easier for sediment to settle to the bottom of the tank under the action of gravity.

[0055] Furthermore, the short arc-shaped pool wall 4 and the long arc-shaped pool wall 5 of this embodiment are arranged concentrically, and the short arc-shaped pool wall 4 and the long arc-shaped pool wall 5 are both closed and connected to the upper edge of the conical pool bottom wall 6; the two ends of the short arc-shaped pool wall 4 and the long arc-shaped pool wall 5 are spaced apart, and the gap between the ends of each short arc-shaped pool wall 4 and the long arc-shaped pool wall 5 is connected to a conveying channel 2; the two ends of the conveying channel 2 are respectively connected to two adjacent pool bodies 1; the bottom of each conical pool bottom wall 6 is connected to a sand discharge mechanism.

[0056] It is worth noting that the diameters of the upper edges of the short arc-shaped pool wall 4, the long arc-shaped pool wall 5 and the conical pool bottom wall 6 of this embodiment are the same.

[0057] It is worth noting that the conveying channel 2 of this embodiment includes two parallel side walls 11 and a bottom plate 10, one side wall 11 is tangentially connected to the end of the long arc-shaped pool wall 5; the other side wall 11 is fixedly connected to the end of the short arc-shaped pool wall 4; the height of the bottom plate 10 is higher than the upper edge of the conical pool bottom wall 6.

[0058] The conveying channel 2 also includes an accelerator pump 12, which is fixedly mounted on the bottom plate 10. The power supply 21 of the control circuit is connected in series with the accelerator pump 12 through a sliding rheostat 35. The accelerator pump 12 is fixedly mounted on the bottom plate 10. Since the direction in which the accelerator pump 12 pushes the water flow is opposite to the direction in which the water enters, then under the action of the water inlet power and the power of the accelerator pump 12, the water flow in the entire pool body 1 is equivalent to forming a force couple, thereby ensuring the generation of a circulation, so that the water flow generates a secondary flow in the pool body 1. However, due to the inclination angle of the conical pool bottom wall 6, the secondary flow will be insufficient to drive the sediment to move upward, so that the sediment will settle downward and gather at the bottom end of the conical pool bottom wall 6 for easy discharge.

[0059] Furthermore, the sand discharge mechanism of this embodiment also includes a connecting pipe 3. One end of the connecting pipe 3 is connected to the pipe between the first ball valve 8 and the upper end of the sand storage bin 7, and the other end of the connecting pipe 3 extends beyond the upper end surface of the tank body 1. The function of the connecting pipe 3 is to balance the pressure inside and outside the sand storage bin 7, preventing pressure imbalance during sand discharge that can lead to poor sand discharge. The connecting pipe 3 can be made of a steel pipe or a plastic pipe, and its diameter should be selected according to actual conditions to ensure effective pressure balance. Specifically, when sand is being stored in the sand storage bin 7, the second ball valve 9 is closed, and the connecting pipe 3 acts as an overflow channel, ensuring that sediment can enter smoothly while water has a place to drain. When the sand storage bin 7 is being discharged, the first ball valve 8 is closed, and the connecting pipe 3 acts as a pressure-balancing pipe, ensuring that sediment can be discharged smoothly from the sand storage bin 7. The connecting pipe 3 is connected to the outside to ensure pressure balance within the sand storage bin 7.

[0060] The operating principle of the sedimentation tank of the present invention is as follows: the sediment-laden water first enters the first tank body 1. Due to the unique structure of tank body 1, as the water flows within tank body 1, the sediment gradually settles onto the conical bottom wall 6. The water then flows through the transfer channel 2 to the next tank body 1 for further sedimentation. Multiple tank bodies 1 are connected in series, allowing the water to undergo multiple sedimentation processes, thereby improving sedimentation efficiency. When sedimentation is required, the drive motor 13 is activated, and the transmission mechanism simultaneously controls the opening and closing of the first and second ball valves 8 and 9. The first ball valve 8 is first opened, allowing the sediment settled at the bottom to enter the sand storage bin 7. The first ball valve 8 is then closed, and the second ball valve 9 is opened to discharge the sediment from the sand storage bin 7. The provision of the connecting pipe 3 ensures pressure balance during the sedimentation process. The design of the multiple tank bodies 1, with their diameters increasing sequentially along the direction of water flow, gradually slows the water flow rate, further improving sedimentation efficiency. Compared to traditional sedimentation tanks, this series-connected funnel-shaped sedimentation tank occupies a smaller footprint, has higher sedimentation efficiency, and is convenient and fast in sedimentation, effectively addressing the problems of existing sedimentation tanks.
