Description

Technical Field

[0001] This invention relates to the field of cement storage technology, specifically to a cement storage device with dust removal function. Background Technology

[0002] With increasingly stringent environmental regulations, the cement industry faces pressure to reduce dust emissions. Storage units with dust collection capabilities can effectively capture and filter cement dust, reducing environmental pollution. Cement dust is harmful to workers' health; long-term exposure can lead to respiratory diseases. By using storage units with dust collection capabilities, dust concentration can be significantly reduced, protecting the health and safety of workers. Cement dust not only impacts the environment and human health but also causes wear and tear on storage equipment and conveying systems. Dust collection devices can reduce dust accumulation, lower equipment wear and tear and the risk of malfunctions, thereby improving the reliability of the production line.

[0003] Existing cement storage facilities typically employ pulse-jet baghouse dust collectors on top of the storage containers for dust removal. These collectors use pulsed airflow to remove dust adhering to the filter bags. However, the jet pipes in these collectors are positioned directly above the filter bags. High-pressure airflow is ejected from evenly distributed jet nozzles on the jet pipe into the inner cavity of the filter bags. The jet nozzles cannot move into the filter bags to achieve comprehensive dust removal, resulting in limited dust collection efficiency. Furthermore, the contact area between the filter bags and dust is relatively small, requiring multiple filter bags to improve efficiency. The prolonged impact of the pulsed airflow also leads to a high breakage rate, making cleaning and replacement of the filter bags cumbersome, complex, and inefficient. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the above-mentioned difficulties and provide a cement storage device with dust removal function.

[0005] To solve the above-mentioned technical problems, the technical solution provided by the present invention is: a cement storage device with dust removal function, including a cement silo, a ladder and guardrail on the cement silo, a discharge port at the bottom, and a feed port and dust collector at the top;

[0006] The dust collector includes a dust collection box fixed to the top of the cement silo. The dust collection box contains several sintered plastic filter plates. The top of the sintered plastic filter plates is provided with a sealing plate. Several jet cleaning dust removal mechanisms that correspond one-to-one with the sintered plastic filter plates are slidably provided on the sealing plate.

[0007] The inner wall of the dust collector is equipped with a mobile power mechanism for driving the jet dust removal mechanism to reciprocate within the plastic sintered filter plate. The outer wall of the dust collector is equipped with a pulse air pump connected to the jet dust removal mechanism, and the opposite side wall is equipped with a blower connected to the dust collector.

[0008] As an improvement, the jet dust removal mechanism includes a fixed frame that is horizontally slidably mounted on a sealing plate. A support frame is mounted on the fixed frame, and a fixed ring is mounted on the support frame. A rotating cylinder is rotatably mounted inside the fixed ring. A bevel gear is mounted on the top of the rotating cylinder to drive its rotation. A first rotating groove that forms a closed loop is mounted around the circumference of the rotating cylinder, and a second rotating groove that forms a fan shape is mounted at the bottom. A vertical moving unit that cooperates with the first rotating groove is slidably mounted inside the fixed frame. An air cylinder that is connected to a pulse air pump is mounted inside the fixed frame. A pair of jet nozzles are mounted at the bottom of the air cylinder. A rotating unit that cooperates with the second rotating groove to drive the air cylinder to rotate is mounted inside the fixed frame. The bottom end of the vertical moving unit is connected to the bottom of the air cylinder.

[0009] As an improvement, the vertical moving unit includes a moving rod slidably disposed in the fixed frame, a protrusion on the moving rod that is slidably connected to a slot in the fixed frame, a connecting rod bent at the top of the moving rod that is slidably connected to a rotating groove, and a connecting plate at the bottom that is fixed to the bottom of the air cylinder.

[0010] As an improvement, the rotating unit includes a sleeve rotatably disposed within a fixed frame. The top of the sleeve is provided with an arc-shaped connecting block that is slidably connected to the rotating groove. The air cylinder is snapped and slidably disposed within the sleeve, and a retaining ring is provided at the bottom end to snap and fix it to the connecting plate.

[0011] As an improvement, the mobile power mechanism includes a slide fixed to the inner wall of the dust collector, a slider slidably mounted inside the slide, a connecting frame fixedly connected to the support frame on the slider, a dual-axis motor fixedly mounted on the top surface of the slider, a gear one fixedly mounted on the output shaft of the dual-axis motor near the inner wall of the dust collector, a gear two rotatably mounted on the side of the slider that meshes with gear one, a crank connecting rod fixedly mounted on the other end of gear two, a crank connecting rod fixedly mounted on the other end of the crank connecting rod, a fixed block opposite the slide on the dust collector, the other end of the crank rotatably mounted on the fixed block, a rotating shaft fixedly connected to the output shaft on the other side of the dual-axis motor, a bevel gear meshing with a bevel gear fixedly mounted on the rotating shaft, a rotating seat slidably mounted in the movable groove on the inner wall of the dust collector, and the other end of the rotating shaft rotatably mounted in the rotating seat.

[0012] As an improvement, the outlet end of the pulse air pump is provided with an air inlet pipe. The air inlet pipe passes through the dust collector and is connected to the air cylinder inside the sleeve. The middle part of the air inlet pipe is a retractable flexible hose structure, and the two ends are rigid pipe structures.

[0013] As an improvement, the sealing plate is provided with a ventilation groove and a sliding groove that communicate with the inner core of the plastic filter plate. The bottom of the fixing frame is provided with a U-shaped slide that is slidably connected to the sliding groove. Several fixing frames are connected together by a connecting crossbar on one side.

[0014] As an improvement, the first rotating groove consists of two horizontal grooves and two inclined grooves connected to each other to form a closed ring structure on the wall of the rotating cylinder, while the second rotating groove is a circular fan-shaped groove structure that expands from the center to the edge on the bottom surface of the rotating cylinder.

[0015] The advantages of this invention compared to the prior art are as follows:

[0016] 1. The sintered plastic filter plate installed in the dust collection box filters the dust, which increases the contact area with the dust and improves the filtration efficiency. The sintered plastic filter plate is also easy and efficient to replace and clean.

[0017] 2. Rotating groove one and rotating groove two on the rotating drum, in conjunction with the vertical moving unit and the rotating unit respectively, can simultaneously drive the air cylinder to reciprocate, move up and down, and move back and forth within the plastic sintered filter plate via a dual-shaft motor, thereby enabling all-round dust removal without dead angles from the plastic sintered filter plate and improving the dust removal effect.

[0018] 3. When the jet nozzle on the air cylinder rotates in the hollow air guide seam of the sintered plastic filter plate, it causes the high-pressure pulse gas to form a wavy airflow in the sintered plastic filter plate. When removing dust from a certain area of ​​the sintered plastic filter plate, it can also make the dust attached to other areas of the sintered plastic filter plate looser, thereby improving the dust removal efficiency.

[0019] 4. The pulse air pump is connected to the air cylinder through the air inlet pipe. When the air cylinder moves back and forth inside the plastic filter plate, the middle part of the air inlet pipe will extend and retract accordingly, so that high-pressure gas can be continuously delivered to the air cylinder, ensuring that the dust removal work can continue.

[0037] The present invention will now be described in further detail with reference to the accompanying drawings.

[0038] Combined with appendix Figure 1 Appendix Figure 2 Appendix Figure 3 Appendix Figure 4 As shown, a cement storage device with dust removal function includes a cement silo 1, a ladder 2 and a guardrail 3 on the cement silo 1, a discharge port 4 at the bottom, and a feed port 5 and a dust collector 6 at the top.

[0039] The dust collector 6 includes a dust collection box 61 fixed to the top of the cement silo 1. The dust collection box 61 contains a number of sintered plastic filter plates 62. The dust collection box 61 has a door on one side corresponding to the sintered plastic filter plates 62. The sintered plastic filter plates 62 have a hollow internal structure and a wave-like structure formed by several rounded edges connected on the outer side of the plate surface. The surface is coated with polytetrafluoroethylene. The sintered plastic filter plates 62 have multi-micron-level micropores distributed on them. The top of the sintered plastic filter plates 62 is provided with a sealing plate 63. A number of jet cleaning dust removal mechanisms 7 are slidably provided on the sealing plate 63, which correspond one-to-one with the sintered plastic filter plates 62. The jet cleaning dust removal mechanism 7 contains a vertical moving unit 76 and a rotating unit 77.

[0040] The inner wall of the dust collector 61 is provided with a mobile power mechanism 8 for driving the jet dust removal mechanism 7 to reciprocate within the plastic filter plate 62. The outer wall of the dust collector 61 is provided with a pulse air pump 9 connected to the jet dust removal mechanism 7, and the opposite side wall is provided with a blower 10 connected to the dust collector 61.

[0041] The working principle of this invention is as follows: When cement is being filled into the cement silo 1, a large amount of dust is generated. At this time, the blower 10 is driven to work, and the dust enters the dust collection box 61. The clean gas filtered by the sintered plastic filter plate 62 is discharged outside the dust collection box 61 through the sealing plate 63 and the blower 10. When a large amount of dust accumulates on the sintered plastic filter plate 62 and needs to be cleaned, the mobile power mechanism 8 drives the jet dust removal mechanism 7 in conjunction with the pulse air pump 9 to remove the dust from the sintered plastic filter plate 62. The cleaned dust falls back into the cement silo 1, completing the dust removal process. The outer side of the sintered plastic filter plate 62 has several rounded edges connected to form a wavy structure, which increases the contact area with dust particles, improves dust removal efficiency, and makes it easy to clean and reuse, as it is not prone to sticking.

[0042] Combined with appendix Figure 4 Appendix Figure 5 Appendix Figure 6 Appendix Figure 7 Appendix Figure 8 Appendix Figure 9 As shown, a fixed frame 71 is horizontally slidably mounted on the sealing plate 63. A support frame 72 is mounted on the fixed frame 71. Two layers of fixed rings 73 are mounted on the support frame 72. A rotating cylinder 74 is rotatably mounted inside the fixed rings 73. A bevel gear 75 is mounted at the top of the rotating cylinder 74 to drive its rotation. A first rotating groove 751 in a closed loop is provided around the circumference of the rotating cylinder 74, and a second rotating groove 752 in a fan shape is provided at the bottom. The first rotating groove 751 consists of two horizontal grooves and two inclined grooves connected to each other on the cylinder wall of the rotating cylinder 74, forming a closed ring structure. The second rotating groove 752 is a circular fan-shaped arc groove structure that expands from the center to the edge on the bottom surface of the rotating cylinder 74. A device connected to a pulse air pump 9 is slidably mounted inside the fixed frame 71. Air pump 11 has a pair of nozzles 111 at its bottom. A movable rod 761 is slidably mounted inside a fixed frame 71. The movable rod 761 has a protrusion 762 that is slidably connected to a slot inside the fixed frame 71. The top of the movable rod 761 is bent and has a connecting rod 763 that is slidably connected to a first rotating groove 751. The bottom of the movable rod 761 has a connecting plate 764 that is fixed to the bottom of the air pump 11. A sleeve 771 is rotatably mounted inside the fixed frame 71. The top of the sleeve 771 has an arc-shaped connecting block 772 that is slidably connected to a second rotating groove 752. The sleeve 771 has a limiting groove. The outer wall of the air pump 11 has a limiting strip that is mates with the limiting groove. The bottom of the sleeve has a retaining ring 112 that is engaged and fixed to the connecting plate 764. A slide 81 is fixedly connected to the upper front and rear inner walls of the dust collector 61. A slider 82 is slidably mounted inside the slide 81. A dual-axis motor 84 is fixedly mounted on the top surface of the slider 82 via a mounting base. A rotating shaft 810 is fixedly connected to the output shaft of the dual-axis motor 84 facing the rotating drum 74. A bevel gear 811 that meshes with the bevel gear 75 is sleeved and fixed on the rotating shaft 810.

[0043] The working principle of the dual-shaft motor 84 driving the air cylinder 11 to move up and down in the filter element of the plastic-coated filter plate 62 is as follows: The output shaft of the dual-shaft motor 84 drives the rotating shaft 810 to rotate. The bevel gear 811, which is sleeved and fixed on the rotating shaft 810, drives the bevel gear 75 to rotate, thereby driving the rotating cylinder 74 to rotate within the fixed ring 73. Since the end of the connecting rod 763 is slidably connected to the rotating groove 751 set on the rotating cylinder 74, and the rotating groove 751 consists of two horizontal grooves and two inclined grooves... The interconnection forms a closed ring structure on the wall of the rotating drum 74. Therefore, when the rotating drum 74 rotates and drives the connecting rod 763 to cooperate with the horizontal groove, the height of the moving rod 761 remains unchanged. When the connecting rod 763 cooperates with the inclined groove, the moving rod 761 moves vertically accordingly, thereby realizing the intermittent up-and-down reciprocating movement of the moving rod 761. Since the connecting plate 764 at the bottom of the moving rod 761 is fixed to the air cylinder 11 by the retaining ring 112, the bottom of the air cylinder 11 can move intermittently up and down within the filter element of the plastic sintered filter plate 62.

[0044] The working principle of the dual-axis motor 84 driving the air cylinder 11 to rotate repeatedly within the filter element of the plastic-coated filter plate 62 is as follows: When the dual-axis motor 84 drives the rotating drum 74 to rotate, the top of the sleeve 771, which is rotatably mounted in the fixed frame 71, is provided with an arc-shaped connecting block 772 that is slidably connected to the rotating groove 752. The rotating groove 752 is a circular fan-shaped arc groove structure that expands from the center to the edge on the bottom surface of the rotating drum 74. Therefore, the rotation of the rotating drum 74 will drive the movable end of the arc-shaped connecting block 772 to swing repeatedly, thereby driving the sleeve 771 to rotate. Since the air cylinder 11 is slidably mounted in the sleeve 771 through the limiting strip and the limiting groove, the air cylinder 11 can rotate repeatedly with the sleeve 771.

[0045] Combined with appendix Figure 4 Appendix Figure 7 Appendix Figure 8 Appendix Figure 9 Appendix Figure 10 Appendix Figure 11 and attached Figure 12As shown, the sealing plate 63 has a pre-reserved ventilation groove 631 and a sliding groove 632 that communicate with the inner core of the plastic filter plate 62. The bottom of the fixing frame 71 is provided with a U-shaped slide 711 that is slidably connected to the sliding groove 632. Several fixing frames 71 are connected together by a connecting crossbar 712 on one side. The fixing frame 71 is provided with a support frame 72. The upper front and rear inner walls of the dust collector 61 are fixedly connected to a slide 81. A slider 82 is slidably provided in the slide 81. The slider 82 is provided with a connecting frame 83 that is fixedly connected to the support frame 72. The dual-axis motor 84 is close to A gear 85 is fixedly sleeved on one side of the inner wall of the dust collector 61. A gear 86 meshing with the gear 85 is rotatably provided on the side of the slider 82. A crank connecting rod 87 is fixedly sleeved on the other end of the gear 86. A crank 88 is rotatably sleeved on the other end of the crank connecting rod 87. A fixed block 89 is provided on the dust collector 61, which is directly opposite to the slide 81. The other end of the crank 88 is rotatably mounted on the fixed block 89. A rotating seat 813 is slidably provided in the moving groove 812 on the inner wall of the dust collector 61. The other end of the rotating shaft 810 is rotatably mounted in the rotating seat 813.

[0046] The working principle of the mobile power mechanism 8 driving the fixed frame 71 to reciprocate back and forth in the dust collector 61 is as follows: When the dual-shaft motor 84 is working, it drives the gear 1 85 to rotate, and the gear 2 86 meshing with the gear 1 85 rotates accordingly, thereby driving the crank connecting rod 87 to rotate. Since the other end of the crank connecting rod 87 is rotatably connected to the crank 88, and the other end of the crank 88 is rotatably set on the fixed block 89, it drives the slider 82 to reciprocate back and forth in the slide 81. Through the connecting frame 83, it drives the fixed frame to reciprocate in the slide groove 632, which in turn drives the air cylinder 11 to reciprocate back and forth in the plastic filter plate 62.

[0047] It is particularly important to note that as the slider 82 moves, it drives the dual-axis motor 84 to move, which in turn drives the rotating shaft 810 to move within the moving slot 812. This allows the rotating shaft 810 to move synchronously with the fixed frame 71, so that the bevel gear 811 on the rotating shaft 810 can always mesh with the bevel gear 75 on the rotating cylinder 74 for transmission. This enables the air cylinder 11 to simultaneously reciprocate, move back and forth, and move up and down, achieving fully automatic and efficient dust removal.

[0048] Combined with appendix Figure 2 Appendix Figure 3 Appendix Figure 13 Appendix Figure 14 Appendix Figure 15 and attached Figure 16As shown, the outlet end of the pulse air pump 9 is provided with an air inlet pipe 91. The air inlet pipe 91 passes through the dust collector 61 and is connected to the air cylinder 11 inside the sleeve 771. The middle part of the air inlet pipe 91 is a retractable flexible hose structure, and the two ends are rigid pipe structures. The lower side of the sealing plate 63 is provided with a mounting bracket 12 that is installed and fixed at the bottom of the dust collector 61. The plastic sintered filter plate 62 is slidably arranged in the mounting bracket 12. The bottom end of the dust collector 61 is provided with a connecting cylinder 13 that is connected to the cement silo 1.

[0049] The working principle of the pulse air pump 9 for dust removal: Dust-laden gas enters the dust collection box 61 through the connecting cylinder 13. After being filtered by the sintered plastic filter plate 62, dust particles and impurities are adsorbed onto the filter plate 62. The filtered clean air is then transported upwards through the hollow air guide slits in the sintered plastic filter plate 62, and conveyed to the upper part of the dust collection box 61 via the air vent 631. It is then transported out of the dust collection box 61 by the blower 10, completing the filtration and dust removal process. High-pressure gas generated by the pulse air pump 9 is delivered to the air cylinder 11 through the air inlet pipe 91, and then ejected through the nozzle 111. The ejected high-pressure airflow blows the dust adsorbed on the sintered plastic filter plate 62 down and into the cement silo 1 through the connecting cylinder 13. When the fixed frame 71 moves, it causes the flexible hose in the middle of the air inlet pipe 91 to extend or retract, thus continuously delivering high-pressure gas to the air cylinder 11. It is worth noting that the air nozzles 111 at the bottom of the air cylinder 11 are arranged opposite each other. The present invention sets the air nozzles 111 as a reciprocating rotating structure, so that the air nozzles 111 are continuously and intermittently aligned with the filter surface and hollow air guide seam of the plastic sintered filter plate 62, so that the high pressure gas forms a wavy airflow in the plastic sintered filter plate 62, thereby improving the dust removal effect.

[0050] In a specific implementation of this invention, when cement is injected into the cement silo 1, due to the pressure difference between the inside and outside, the dust generated inside the cement silo 1 will be discharged into the dust collection box 61 along with the gas through the connecting cylinder 13. At this time, the blower 10 is driven to work, and the clean air after the gas containing dust is filtered by the plastic sintered filter plate 62 is discharged outside the dust collection box 61 through the sealing plate 63 and the blower 10. The dust will be filtered and adsorbed on the surface of the plastic sintered filter plate 62. When too much dust accumulates on the surface of the plastic sintered filter plate 62, the dual-shaft motor 84 is driven simultaneously. Working in conjunction with the pulse air pump 9, the output shafts on both sides of the dual-shaft motor 84 simultaneously drive the air cylinder 11 to reciprocate, move up and down intermittently, and move back and forth within the sintered plastic filter plate 62. The high-pressure airflow output by the pulse air pump 9 is delivered to the air cylinder 11 through the air inlet pipe 91, and then ejected through the jet nozzle 111, causing the high-pressure gas to form a wavy airflow within the sintered plastic filter plate 62, blowing off the dust accumulated on the surface of the sintered plastic filter plate 62, improving the dust removal effect and achieving full automation. The removed dust falls into the cement silo 1, completing the dust removal process.

[0051] It is worth mentioning that the dual-axis motor 84, pulse air pump 9, and blower 10 in this invention are all existing devices well known to those skilled in the art, and their circuit connection methods and usage control methods are all existing technologies.

[0052] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the spirit of the invention, such designs should fall within the protection scope of the present invention.
