Description

Technical Field

[0001] This invention relates to the field of transportation equipment technology, specifically to a transportation device for port terminals with a dust-proof structure. Background Technology

[0002] Transportation equipment is a carrier that transports goods from one place to another. Transportation devices located at ports and wharves are usually used for transporting bulk goods such as powders and grains. When the gantry crane grabs material above the bulk cargo hopper and opens the grab, the material falls freely into the hopper under the influence of gravity. As a large amount of material falls, it carries a large amount of air into the hopper. Smaller particles and particles with lower density will be diffused outward by the airflow, which will generate a large amount of dust and pollute the surrounding air environment.

[0003] For example, the port terminal transport device with a dust-proof structure, as described in announcement number CN219408466U, includes a receiving hopper body, a discharge port, and a dust removal mechanism. A rotating mechanism moves the grabbed grain to the top of the receiving hopper body for unloading via a grab bucket. During this process, the grain undergoes initial dust removal through multiple dust removal heads. When the grain falls along the inner wall of the receiving hopper body into the inner cavity of the discharge port, a fan is activated, and the dust removal mechanism removes dust from the grain passing through the discharge port's inner cavity. Simultaneously, a ring filter filters the grain from the dust. At the same time, a motor drives a bevel gear to rotate, at which point the grain passes through the mounting base, ring filter, and... The combination of the bevel gear ring and the aforementioned parts can minimize the waste of grain and prevent the annular filter screen from becoming clogged with grain, thus avoiding difficulties in dust removal. However, for materials with high dust content, such as coal, when the material is transported to the hopper by the grabber at the dock, the dust extraction and material filtration by the filter screen may still result in some dust not being extracted and collected in time. This dust will continue to dissipate into the air, and with the extension of the working cycle, it may still cause dust pollution at the dock. In addition, the material may also contain a small amount of fine material. After being extracted, this fine material may clog the filter screen pores, reducing the effectiveness of subsequent negative pressure dust extraction.

[0004] Therefore, a transportation device with a dust-proof structure for port terminals is proposed to solve the aforementioned problems. Summary of the Invention

[0005] The purpose of this invention is to provide a transportation device with a dust-proof structure for port terminals, in order to solve the problem that even when dust is extracted by negative pressure and materials are filtered by a filter screen, a small amount of dust may still not be extracted and collected in time, and this dust will continue to escape into the air, causing dust pollution at the terminal.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a transport device for port terminals with a dust-proof structure, comprising a receiving hopper and a conical hopper fixedly installed at the bottom of the receiving hopper, wherein the top of the receiving hopper is provided with a feed inlet;

[0007] Also includes:

[0008] A filter cartridge is fixedly installed on the inner top surface of the receiving hopper, and dust removal components are symmetrically arranged on both sides of the receiving hopper. A scraping component is symmetrically arranged on the inner side of the filter cartridge.

[0009] The dust removal assembly includes a water inlet unit and a scraping unit. The water inlet unit includes a mounting box symmetrically and fixedly installed on the outside of the receiving hopper. A connecting pipe is fixedly installed on the top of the mounting box. The same water inlet pipe is connected between two adjacent connecting pipes. A water outlet pipe is fixedly installed on the bottom of the mounting box. A connecting pipe is connected to the side of the water outlet pipe away from the mounting box. A spray head is connected to the end of the connecting pipe away from the water outlet pipe.

[0010] The scraping unit includes an internal gear rotatably mounted inside the mounting box, and a main bevel gear rotatably mounted on the outside of the mounting box. The internal gear and the main bevel gear rotate synchronously. The scraping unit also includes a rotating shaft symmetrically rotatably mounted on the outside of the receiving hopper. A driven bevel gear is fixedly connected to the outside of the rotating shaft. A limit sleeve is fixedly connected to one end of the rotating shaft, and a reciprocating screw is fixedly connected between two adjacent limit sleeves.

[0011] Preferably, a cover plate is rotatably installed on both the front and back sides of the receiving hopper, a sealing plate is fixedly connected inside the receiving hopper, the sealing plate is fixed to the bottom surface of the filter cartridge, filter holes are evenly opened on the side of the filter cartridge, a fixing plate is fixedly connected between the mounting box and the receiving hopper, a movable sleeve is sleeved on the outside of the reciprocating screw, a vertical rod is fixedly connected to the top of the movable sleeve, a horizontal column is fixedly installed on one side of the vertical rod, the scraping assembly includes a cleaning rod rotatably installed on one side of the horizontal column, the cleaning rod is in contact with the inner ring of the filter cartridge, a rotating rod is rotatably connected to the side of the mounting box near the reciprocating screw, one end of the rotating rod is fixedly connected to an internal gear, and the other end of the rotating rod is fixedly connected to a main bevel gear.

[0012] By adopting the above technical solution, when the grab bucket opens to unload material, the external pressurized water source enters the connecting pipe through the inlet pipe, and then enters the installation box through the connecting pipe. The pressurized water source passes through the outlet pipe and the connecting pipe in sequence, and is sprayed out from the spray head, which facilitates the washing and dust suppression of the material.

[0013] Preferably, the number of water outlet pipes is the same as that of the installation box, only one connecting pipe is provided, and there are no fewer than three spray heads. The spray heads are fixedly installed to the receiving hopper, and the end of the spray head away from the connecting pipe is located inside the receiving hopper. The other end of the rotating shaft is fixedly connected to an installation plate, and the installation plate is fixedly connected to the receiving hopper.

[0014] By adopting the above technical solution, the pressurized water source impact will drive the internal gear to rotate, the internal gear will drive the rotating rod and the main bevel gear to rotate, the main bevel gear will drive the driven bevel gear and the rotating shaft to rotate, and the rotating shaft will drive the reciprocating screw to rotate.

[0015] Preferably, the left and right sides of the receiving hopper are fixedly connected to limit frames, the vertical rod is slidably connected to the limit frames, the top of the receiving hopper is symmetrically provided with sliding grooves, and the bottom of the horizontal column is fixedly installed with rollers.

[0016] By adopting the above technical solution, the limiting frame limits the vertical rod, so that the moving sleeve drives the vertical rod to move linearly back and forth outside the reciprocating screw. The limiting sleeve is used to limit the moving sleeve, and the vertical rod drives the horizontal column and the sliding rod to move.

[0017] Preferably, the roller rolls inside the groove, and the horizontal column has an inner groove on the side away from the vertical rod, with a spring fixedly connected to the inner side of the inner groove.

[0018] By adopting the above technical solution, as the horizontal column moves linearly, the cleaning rod will adapt to the change in the inner curvature of the filter cartridge, so that the elastic force of spring one will pull the sliding rod, and the sliding rod will continuously drive the cleaning rod closer to the inner side of the filter cartridge.

[0019] Preferably, a slide rod is slidably installed inside the inner groove, one end of the slide rod is fixedly connected to a spring, and the other end of the slide rod is located outside the crossbar.

[0020] By adopting the above technical solution, dust removal components are installed on both sides of the outer side of the receiving hopper. The two dust removal components facilitate the scraping of the two half-circles of the filter cartridge, thereby achieving the overall scraping and cleaning of the inner circle of the filter cartridge.

[0021] Preferably, the scraping assembly includes a fixed rod fixedly connected to the bottom of the other end of the slide rod, the fixed rod being rotatably connected to the cleaning rod, a torsion spring being sleeved on the outer side of the fixed rod, the top end of the torsion spring being fixedly connected to the slide rod, and the bottom end of the torsion spring being fixedly connected to the cleaning rod.

[0022] By adopting the above technical solution, the external pipe is connected to the exhaust fan, and the exhaust fan outlet is connected to the dust filter bag. The exhaust fan draws air through the external pipe, the converging pipe and the suction pipe, so that the small amount of smoke and dust that has not been completely sprayed can be removed.

[0023] Preferably, a suction pipe is fixedly installed inside the cover plate, and there are no fewer than three suction pipes. The end of each suction pipe away from the filter cartridge is connected to the same converging pipe. The side of the converging pipe away from the suction pipe is connected to an external connecting pipe. The external connecting pipe is connected to the suction pipe through the converging pipe. The suction pipe is located above the sealing plate.

[0024] By adopting the above technical solution, the smoke and dust pass through the suction pipe, the collection pipe and the external pipe in sequence, and then enter the dust filter bag for treatment through the exhaust fan.

[0025] Preferably, the cleaning rod has a sliding groove evenly distributed on the side near the filter cylinder, a second spring is fixedly installed inside the sliding groove, a hemispherical block is slidably connected inside the sliding groove, the hemispherical block corresponds to each row of the filter holes, the hemispherical block is fixedly connected to the second spring, and the cleaning rod also has an installation groove evenly distributed on the side near the filter cylinder, a cleaning roller is rotatably installed inside the installation groove.

[0026] By adopting the above technical solution, the cleaning rod will also rotate when it moves, and the cleaning rod will always be in close contact with the inner ring of the filter cartridge. The movement of the cleaning rod will drive the cleaning roller to move, and the cleaning roller will also rotate when it comes into contact with the filter cartridge.

[0027] Compared with the prior art, the beneficial effects of the present invention are:

[0028] By incorporating a dust removal component, an external material grabber uses a grab bucket to grab materials and places it inside the receiving hopper. The inlet pipe connects to an external pressurized water source. When the grab bucket opens to discharge material, the external pressurized water flows through the inlet pipe into the connecting pipe, and then into the mounting box. The pressurized water then passes through the outlet pipe and connecting pipe before being sprayed from the spray nozzle, facilitating material washing and dust suppression. The impact of the pressurized water source drives the internal gear to rotate, which in turn drives the rotating rod and main bevel gear. The main bevel gear drives the driven bevel gear and rotating shaft to rotate, which in turn drives the reciprocating screw. A limit frame limits the vertical rod, causing the moving sleeve to move the vertical rod linearly back and forth outside the reciprocating screw. The limit sleeve also limits the movement of the moving sleeve. The vertical rod drives the horizontal column and sliding rod to move, and the horizontal column drives the rollers. Sliding inside the chute, the sliding rod drives the cleaning rod to move. The cleaning rod scrapes the inside of the filter cylinder, thereby reducing material adhesion on the filter cylinder and improving the dust extraction effect. As the horizontal column moves linearly, the cleaning rod adapts to the change in the inner curvature of the filter cylinder, causing the spring force to pull the sliding rod, which keeps the sliding rod close to the inner side of the filter cylinder. Dust removal components are installed on both sides of the receiving hopper. The two dust removal components facilitate scraping the two half-circles of the filter cylinder separately, thereby achieving overall scraping and cleaning of the inner circle of the filter cylinder. This solves the problem that a small amount of dust may not be extracted and collected in time when dust is extracted by negative pressure and materials are filtered by the filter screen. This dust will continue to escape into the air, causing dust pollution at the dock.

[0029] By setting up a scraping assembly, the external pipe is connected to the exhaust fan, and the exhaust fan's outlet is connected to the dust filter bag. The exhaust fan draws air through the external pipe, the converging pipe, and the suction pipe, allowing a small portion of the dust that has not been completely sprayed to be extracted through the filter holes on the filter cartridge. The dust then passes sequentially through the suction pipe, the converging pipe, and the external pipe, before entering the dust filter bag for processing via the exhaust fan. The cleaning rod and the fixed rod rotate, causing the cleaning rod to rotate as it moves. The cleaning rod remains tightly fitted against the inner ring of the filter cartridge, and its movement drives the cleaning roller to move. The cleaning roller rotates upon contact with the filter cartridge. An installation groove is provided on the cleaning rod for mounting the cleaning roller. As the cleaning roller rotates, debris on its outer side is scraped off by the side end of the installation groove. The movement of the cleaning rod also moves the hemispherical block. When the hemispherical block moves to the filter hole section, the elastic force of spring two causes the hemispherical block to engage with the filter hole section a short distance. The arc-shaped surface of the hemispherical block prevents it from getting stuck in the filter hole section, thus achieving a cleaning effect on the filter hole section and maintaining the flow of the filter cartridge and the extraction effect of smoke and dust.

[0045] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0046] Please see Figure 1 - Figure 3 The present invention provides a technical solution: a transportation device with a dust-proof structure for port terminals, including a receiving hopper 1 and a conical hopper 2 fixedly installed at the bottom of the receiving hopper 1, and a feeding port 3 is provided at the top of the receiving hopper 1.

[0047] A filter cartridge 4 is fixedly installed on the inner top surface of the receiving hopper 1, and dust removal components 5 are symmetrically arranged on both sides of the receiving hopper 1.

[0048] The dust removal assembly 5 includes a water inlet unit and a scraping unit. The water inlet unit includes a mounting box 52 symmetrically and fixedly installed on the outside of the receiving hopper 1. A connecting pipe 53 is fixedly installed on the top of the mounting box 52. The same water inlet pipe 54 is connected between two adjacent connecting pipes 53. A water outlet pipe 58 is fixedly installed on the bottom of the mounting box 52. A connecting pipe 59 is connected to the side of the water outlet pipe 58 away from the mounting box 52. A spray head 510 is connected to the end of the connecting pipe 59 away from the water outlet pipe 58.

[0049] The scraping unit includes an internal gear 56 rotatably mounted inside the mounting box 52. A main bevel gear 57 is also rotatably mounted on the outside of the mounting box 52. The internal gear 56 and the main bevel gear 57 rotate synchronously. The scraping unit also includes a rotating shaft 512 symmetrically rotatably mounted on the outside of the receiving hopper 1. A driven bevel gear 513 is fixedly connected to the outside of the rotating shaft 512. A limit sleeve 514 is fixedly connected to one end of the rotating shaft 512. A reciprocating screw 515 is fixedly connected between two adjacent limit sleeves 514.

[0050] A cover plate 7 is rotatably installed on both the front and back sides of the receiving hopper 1. A sealing plate 8 is fixedly connected inside the receiving hopper 1. The sealing plate 8 is fixed to the bottom surface of the filter cylinder 4. Filter holes 9 are evenly opened on the side of the filter cylinder 4. A fixing plate 51 is fixedly connected between the mounting box 52 and the receiving hopper 1. A movable sleeve 516 is sleeved on the outside of the reciprocating screw 515. A vertical rod 517 is fixedly connected to the top of the movable sleeve 516. A horizontal column 519 is fixedly installed on one side of the vertical rod 517. The scraping assembly 6 includes a cleaning rod 63 rotatably installed on one side of the horizontal column 519. The cleaning rod 63 is in contact with the inner ring of the filter cylinder 4. A rotating rod 55 is rotatably connected to the side of the mounting box 52 near the reciprocating screw 515. One end of the rotating rod 55 is fixedly connected to the internal gear 56, and the other end of the rotating rod 55 is fixedly connected to the main bevel gear 57.

[0051] The number of water outlet pipes 58 is the same as that of the installation box 52. Only one connecting pipe 59 is provided. There are no less than three spray heads 510. The spray head 510 is fixedly installed with the receiving hopper 1, and the end of the spray head 510 away from the connecting pipe 59 is located inside the receiving hopper 1. The other end of the rotating shaft 512 is fixedly connected to the mounting plate 511, and the mounting plate 511 is fixedly connected to the receiving hopper 1.

[0052] Limit frames 518 are fixedly connected to both the left and right sides of the receiving hopper 1. The vertical rod 517 is slidably connected to the limit frames 518. The top of the receiving hopper 1 is symmetrically provided with sliding grooves 520. Rollers 521 are fixedly installed at the bottom of the horizontal column 519.

[0053] Roller 521 rolls inside the slide groove 520. The horizontal column 519 has an inner groove 522 on the side away from the vertical rod 517. A spring 523 is fixedly connected to one side of the inner groove 522. A slide rod 524 is slidably installed inside the inner groove 522. One end of the slide rod 524 is fixedly connected to the spring 523, and the other end of the slide rod 524 is located outside the horizontal column 519.

[0054] Example 1: As Figure 4 - Figure 10 As shown, the external grabber grabs materials through the grab bucket and places the grab bucket inside the receiving hopper 1. The water inlet pipe 54 is connected to an external pressurized water source. When the grab bucket opens to discharge materials, the external pressurized water source enters the connecting pipe 53 through the water inlet pipe 54, and then enters the installation box 52 through the connecting pipe 53. The pressurized water source passes through the water outlet pipe 58 and the connecting pipe 59 in sequence, and is sprayed out from the spray head 510 to facilitate the washing and dust suppression of materials.

[0055] The pressurized water source impact drives the internal gear 56 to rotate, which in turn drives the rotating rod 55 and the main bevel gear 57 to rotate. The main bevel gear 57 drives the driven bevel gear 513 and the rotating shaft 512 to rotate, and the rotating shaft 512 drives the reciprocating screw 515 to rotate. The limiting frame 518 limits the vertical rod 517, causing the moving sleeve 516 to drive the vertical rod 517 to move linearly back and forth outside the reciprocating screw 515. The limiting sleeve 514 is used to limit the moving sleeve 516. The vertical rod 517 drives the horizontal column 519 and the sliding rod 524 to move. The horizontal column 519 drives the roller 521 to slide inside the slide groove 520. The sliding rod 524 drives the cleaning rod 63 to move. The cleaning rod 63 scrapes the inside of the filter cartridge 4, thereby reducing the material adhesion on the filter cartridge 4 and improving the dust extraction effect.

[0056] Furthermore, as the horizontal column 519 moves linearly, the cleaning rod 63 adapts to the change in the inner curvature of the filter cylinder 4, causing the elastic force of the spring 523 to pull the sliding rod 524. This causes the sliding rod 524 to continuously drive the cleaning rod 63 closer to the inner side of the filter cylinder 4. Dust removal components 5 are provided on both outer sides of the receiving hopper 1. The two dust removal components 5 facilitate scraping the two half-circles of the filter cylinder 4 respectively, thereby achieving overall scraping and cleaning of the inner circle of the filter cylinder 4. This solves the problem that, even with negative pressure extraction of dust and material filtration by the filter screen, a small amount of dust may still not be extracted and collected in time. This dust will continue to dissipate into the air, causing dust pollution at the dock.

[0057] The inner side of the filter cartridge 4 is symmetrically provided with scraping components 6. The scraping components 6 include a fixed rod 61 fixedly connected to the bottom of the other end of the slide rod 524. The fixed rod 61 is rotatably connected to the cleaning rod 63. A torsion spring 62 is sleeved on the outer side of the fixed rod 61. The top end of the torsion spring 62 is fixedly connected to the slide rod 524, and the bottom end of the torsion spring 62 is fixedly connected to the cleaning rod 63.

[0058] The cover plate 7 has a fixedly installed suction pipe 64. There are no fewer than three suction pipes 64. The end of the suction pipe 64 away from the filter cartridge 4 is connected to the same converging pipe 65. The side of the converging pipe 65 away from the suction pipe 64 is connected to an external pipe 66. The external pipe 66 is connected to the suction pipe 64 through the converging pipe 65. The suction pipe 64 is located above the sealing plate 8.

[0059] The cleaning rod 63 has evenly spaced sliding grooves 67 on the side near the filter cylinder 4. A second spring 68 is fixedly installed inside the sliding groove 67. A hemispherical block 69 is slidably connected inside the sliding groove 67. The hemispherical block 69 corresponds to each row of filter holes 9. The hemispherical block 69 is fixedly connected to the second spring 68. The cleaning rod 63 also has evenly spaced mounting grooves on the side near the filter cylinder 4. A cleaning roller 610 is rotatably installed inside the mounting groove.

[0060] Example 2: Figure 10 - Figure 14 As shown, the external pipe 66 is connected to the exhaust fan, and the exhaust fan outlet is connected to the dust filter bag. The exhaust fan draws air through the external pipe 66, the converging pipe 65, and the suction pipe 64, so that a small portion of the dust that has not been completely sprayed is drawn out through the filter holes 9 on the filter cartridge 4. The dust passes through the suction pipe 64, the converging pipe 65, and the external pipe 66 in sequence, and then enters the dust filter bag for processing through the exhaust fan. The cleaning rod 63 and the fixed rod 61 rotate, so that the cleaning rod 63 will also rotate when it moves. The cleaning rod 63 is always in close contact with the inner ring of the filter cartridge 4. The movement of the cleaning rod 63 drives the cleaning roller 610 to move. The cleaning roller 610 will also rotate when it comes into contact with the filter cartridge 4.

[0061] A mounting groove is provided on the cleaning rod 63 for mounting the cleaning roller 610. When the cleaning roller 610 rotates, the debris on the outside of the cleaning roller 610 will be scraped off by the side end face of the mounting groove. The movement of the cleaning rod 63 will also drive the hemispherical block 69 to move. When the hemispherical block 69 moves to the position of the filter hole 9, the elastic force of the second spring 68 will drive the hemispherical block 69 to be inserted into the filter hole 9 a short distance. The arc-shaped surface of the hemispherical block 69 will prevent it from getting stuck in the filter hole 9, thereby achieving the cleaning effect of the filter hole 9 and maintaining the flow of the filter cartridge 4 and the dust extraction effect.

[0062] Working principle: When using this device, firstly, as... Figure 1 - Figure 14As shown, the external grabber grabs materials using a grab bucket and places the grab bucket inside the receiving hopper 1. The water inlet pipe 54 is connected to an external pressurized water source. When the grab bucket opens to discharge materials, the external pressurized water source enters the connecting pipe 53 through the water inlet pipe 54, and then enters the mounting box 52 through the connecting pipe 53. The pressurized water source passes through the water outlet pipe 58 and the connecting pipe 59 in sequence, and is sprayed out from the spray head 510, facilitating material washing and dust suppression. The external pipe 66 is connected to the exhaust fan, and the exhaust fan's outlet is connected to the dust filter bag. A small portion of the smoke and dust that is not completely sprayed is drawn out through the filter holes 9 on the filter cartridge 4. The smoke and dust then pass through the suction pipe 64, the collecting pipe 65, and the external pipe 66, and are then processed in the dust bag by the exhaust fan. The pressurized water impact drives the internal gear 56 to rotate, which in turn drives the rotating rod 55 and the main bevel gear 57 to rotate. The main bevel gear 57 drives the driven bevel gear 513 and the rotating shaft 512 to rotate, and the rotating shaft 512 drives the reciprocating screw 515 to rotate. The vertical rod 517 will move linearly upwards. The moving sleeve 514 limits the movement of the moving sleeve 516. The vertical rod 517 drives the horizontal column 519 and the sliding rod 524 to move. The sliding rod 524 drives the cleaning rod 63 to move. The cleaning rod 63 scrapes the inside of the filter cartridge 4, thereby reducing the material adhesion on the filter cartridge 4 and improving the dust extraction effect. As the horizontal column 519 moves linearly, the cleaning rod 63 adapts to the change in the inner curvature of the filter cartridge 4, so that the elastic force of the spring 523 pulls the sliding rod 524, causing the sliding rod 524 to move. The cleaning rod 63 will continuously move closer to the inner side of the filter cylinder 4, and the cleaning rod 63 will always be tightly attached to the inner ring of the filter cylinder 4. The movement of the cleaning rod 63 will drive the cleaning roller 610 to move. The cleaning roller 610 will also rotate when it comes into contact with the filter cylinder 4. The debris on the outside of the cleaning roller 610 will be scraped off and fall off by the side end face of the mounting groove. When the hemispherical block 69 moves to the position of the filter hole 9, the elastic force of the second spring 68 will drive the hemispherical block 69 to be inserted into the filter hole 9 a short distance, which will achieve the cleaning effect of the filter hole 9.
