Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of transportation devices, in particular to a transportation device with dust prevention structure for port wharf. BACKGROUND

[0002] The transportation device is a carrier for transporting goods from one place to another. The transportation device located at the port wharf is usually used for transporting bulk cargo such as powder and grain. When the grab bucket of the door machine is above the bulk hopper and is opened, the material will freely fall into the hopper under the influence of gravity. With the large amount of material falling, a large amount of air will enter the hopper, and the small particles with small mass and the particles with small density will be diffused outward by the airflow, thereby generating a large amount of dust, which pollutes the surrounding air environment.

[0003] For example, the port wharf transportation device with dust prevention structure disclosed in the patent No. CN219408466U includes a material receiving hopper body, a discharge port, and a dust removal mechanism. The grain material grabbed by the grab bucket is moved to the top of the material receiving hopper body for unloading. In this process, the grain material is preliminarily dusted by the plurality of dust removal heads. When the grain material falls along the inner wall of the material receiving hopper body into the inner cavity of the discharge port, the fan is started to remove dust from the grain material passing through the inner cavity of the discharge port through the dust removal mechanism. At the same time, the grain material in the dust is filtered through the annular filter screen. The motor is started to drive the bevel gear to rotate. At this time, through the cooperation of the mounting seat, the annular filter screen, the bevel gear ring, and the above-mentioned parts, the waste of grain material can be minimized, and the annular filter screen can be prevented from being blocked by grain material, thereby preventing the dust removal operation from being difficult to perform. However, for materials containing a large amount of dust such as coal, when the material is transported to the hopper by the grab bucket, the dust may not be timely extracted and collected through the negative pressure extraction and filter screen filtration of the material. These dusts will continue to escape into the air, and with the extension of the working period, the port may still be polluted by dust. In addition, the material may also include a small amount of fine material. After the fine material is extracted, it may be blocked in the filter hole of the filter screen, thereby reducing the effect of subsequent negative pressure extraction and dust removal.

[0004] Therefore, a port wharf transportation device with dust prevention structure is proposed to solve the above problems. SUMMARY

[0005] The present application aims to provide a port wharf transportation device with dust prevention structure to solve the problem that a small amount of dust may not be timely extracted and collected through the negative pressure extraction and filter screen filtration of the material, which may continue to escape into the air, thereby causing dust pollution at the port.

The end of the dust suction pipe away from the filter cartridge is connected to the same converging pipe, and the side of the converging pipe away from the dust suction pipe is connected to an external pipe. The external pipe is connected to the dust suction pipe through the converging pipe, and the dust suction pipe is located above the sealing plate.

[0022] Through the above technical scheme, when the cleaning rod moves, it also rotates, and the cleaning rod is always closely attached to the inner ring of the filter cartridge.

[0023] Compared with the prior art, the present application has the following advantages: By setting the dust removal assembly, the external grab bucket grabs the material, and the grab bucket is placed in the receiving hopper. The water inlet pipe is connected with the external pressurized water source. When the grab bucket is opened to discharge the material, the external pressurized water source enters the connecting pipe through the water inlet pipe, and then enters the installation box through the connecting pipe. The pressurized water source successively passes through the water outlet pipe and the connecting pipe, and is sprayed from the spray head. This facilitates the washing and dust removal of the material, and the impact of the pressurized water source drives the inner gear to rotate. The inner gear drives the rotating rod and the main bevel gear to rotate. The main bevel gear drives the driven bevel gear and the rotating shaft to rotate. The rotating shaft drives the reciprocating screw rod to rotate. The limiting frame limits the vertical rod, so that the moving sleeve drives the vertical rod to move linearly on the outside of the reciprocating screw rod. The limiting sleeve is used to limit the moving sleeve. The vertical rod drives the horizontal column and the sliding rod to move. The horizontal column drives the roller to slide in the sliding groove. The sliding rod drives the cleaning rod to move. The cleaning rod scrapes and removes the inside of the filter cartridge, thereby reducing the adhesion of the material on the filter cartridge and improving the smoke dust extraction effect. As the horizontal column moves linearly, the cleaning rod will adapt to the change in the inner side curvature of the filter cartridge. The spring force of the spring will pull the sliding rod, so that the sliding rod will always drive the cleaning rod to approach the inner side surface of the filter cartridge. The receiving hopper is provided with dust removal assemblies on the two sides. The two dust removal assemblies facilitate the scraping and removal of the two semicircles on the two sides of the filter cartridge, thereby realizing the overall scraping and cleaning of the inner ring of the filter cartridge. The problem of dust pollution at the wharf caused by the fact that a small amount of dust may not be timely extracted and collected through the negative pressure extraction and filter screen material filtering modes is solved. By setting a scraping component, the external pipe is connected to the exhaust fan, and the air outlet of the exhaust fan is connected to the dust bag. The exhaust fan extracts air through the external pipe, the gathering pipe and the dust suction pipe, so that a small amount of smoke and dust that has not been completely sprayed is extracted through the filter holes on the filter cartridge. The smoke and dust pass through the dust suction pipe, the gathering pipe and the external pipe in turn, and enter the dust filter bag through the exhaust fan for processing. The cleaning rod and the fixed rod rotate, so that when the cleaning rod moves, it will also rotate. The cleaning rod is always closely attached to the inner ring of the filter cartridge, and the movement of the cleaning rod drives the cleaning roller to move When the cleaning roller moves, it will contact the filter cartridge and rotate. A mounting groove is provided on the cleaning rod for installing the cleaning roller, so that when the cleaning roller rotates, the debris on the outside of the cleaning roller will be scraped off and fall off by the side end surface of the mounting groove. The movement of the cleaning rod will also drive the hemispherical block to move. When the hemispherical block moves to the position of the filter hole, the elastic force of the second spring will drive the hemispherical block to be stuck in the filter hole for a short distance. The arc surface of the hemispherical block is set so that it will not be stuck in the filter hole, thereby playing a cleaning effect on the filter hole and maintaining the flowability of the filter cartridge and the smoke and dust extraction effect.

The spray heads 510 are fixedly installed on 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.

[0035] Example 1: Figure 4 - Figure 10As shown, the external grabber grabs the material through the grab bucket and places the grab bucket inside the receiving hopper 1. The water inlet pipe 54 is connected to the external pressurized water source. When the grab bucket is opened to discharge the material, 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 turn, and is sprayed out from the spray head 510, which is convenient for washing and dust reduction of the material.

[0036] The impact of the pressurized water source will drive the internal gear 56 to rotate, and the internal gear 56 drives the rotating rod 55 and the main bevel gear 57 to rotate. The main bevel gear 57 drives the slave bevel gear 513 and the rotating shaft 512 to rotate, and the rotating shaft 512 drives the reciprocating screw rod 515 to rotate. The limit frame 518 limits the vertical rod 517, so that the movable sleeve 516 drives the vertical rod 517 to move back and forth in a straight line outside the reciprocating screw rod 515. The limit sleeve 514 is used to limit the movable 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 inner side of the filter cartridge 4, thereby reducing the material adhesion on the filter cartridge 4 and improving the smoke extraction effect.

[0037] And as the horizontal column 519 moves linearly, the cleaning rod 63 will adapt to the change in the inner curvature of the filter cartridge 4, so that the elastic force of the spring 1 523 will pull the slide bar 524, so that the slide bar 524 will always drive the cleaning rod 63 close to the inner side of the filter cartridge 4. Dust removal components 5 are provided on both sides of the outside of the hopper 1. The two dust removal components 5 are convenient for scraping the half circles on both sides of the filter cartridge 4 respectively, thereby realizing the overall scraping and cleaning of the inner circle of the filter cartridge 4, solving the method of extracting dust and filtering materials through negative pressure. There may still be a small amount of dust that is not extracted and collected in time. This dust will continue to escape into the air, causing dust pollution at the terminal.

[0038] A scraping assembly 6 is symmetrically arranged on the inner side of the filter cartridge 4. The scraping assembly 6 includes a fixed rod 61 fixedly connected to the bottom of the other end of the sliding 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 sliding rod 524, and the bottom end of the torsion spring 62 is fixedly connected to the cleaning rod 63.

[0039] A dust suction pipe 64 is fixedly installed inside the cover plate 7, and there are no less than three dust suction pipes 64. The end of the dust suction pipe 64 away from the filter cartridge 4 is connected to the same converging pipe 65, and the side of the converging pipe 65 away from the dust suction pipe 64 is connected to an external pipe 66. The external pipe 66 is connected to the dust suction pipe 64 through the converging pipe 65. The dust suction pipe 64 is located above the sealing plate 8.

[0040] The cleaning rod 63 is uniformly provided with a sliding groove 67 close to one side of the filter cartridge 4, the sliding groove 67 is fixedly installed with a spring 68 inside, and the sliding groove 67 is slidably connected with a hemispherical block 69, the hemispherical block 69 corresponds to each column of the filter hole part 9, the hemispherical block 69 is fixedly connected with the spring 68, and the cleaning rod 63 is also uniformly provided with a mounting groove close to one side of the filter cartridge 4, and the mounting groove is rotatably installed with a cleaning roller 610.

[0041] Embodiment two: as shown in Figure 10 Figure 14 The outer connecting pipe 66 is connected with the air extractor, and the air outlet of the air extractor is connected with the dust filter bag. The air extractor draws air through the outer connecting pipe 66, the converging pipe 65 and the dust suction pipe 64, so that a small part of smoke dust that is not completely treated by spraying is extracted through the filter hole part 9 on the filter cartridge 4. The smoke dust passes through the dust suction pipe 64, the converging pipe 65 and the outer connecting pipe 66 in turn, and enters the dust filter bag through the air extractor for treatment. The cleaning rod 63 rotates with the fixed rod 61, so that the cleaning rod 63 rotates when moving. The cleaning rod 63 is always closely attached to the inner ring of the filter cartridge 4. The cleaning rod 63 moves to drive the cleaning roller 610 to move. The cleaning roller 610 rotates when contacting the filter cartridge 4.

[0042] The mounting groove on the cleaning rod 63 is used to install the cleaning roller 610, so that the foreign matter on the outside of the cleaning roller 610 can be scraped off by the side end face of the mounting groove when the cleaning roller 610 rotates. The movement of the cleaning rod 63 also drives the movement of the hemispherical block 69. When the hemispherical block 69 moves to the position of the filter hole part 9, the elastic force of the spring 68 drives the hemispherical block 69 to be clamped into the filter hole part 9 for a small distance. The arc surface of the hemispherical block 69 is arranged so as not to be clamped in the filter hole part 9, thereby achieving the cleaning effect of the filter hole part 9 and maintaining the flowability of the filter cartridge 4 and the extraction effect of the smoke dust.

[0043] Working principle: when using the device, first, Figure 1 Figure 14 ​​As shown, the external grab bucket grabs the material through the grab bucket, and places the grab bucket inside the receiving hopper 1. The inlet pipe 54 is connected to the external pressurized water source. When the grab bucket is opened to discharge the material, the external pressurized water source enters the communication pipe 53 through the inlet pipe 54, and then enters the mounting box 52 through the communication pipe 53. The pressurized water source is sequentially discharged from the spray head 510 through the outlet pipe 58 and the connecting pipe 59, so as to facilitate the flushing and dust removal treatment of the material. The external pipe 66 is connected to the air extractor, and the air outlet of the air extractor is connected to the dust filter bag. A small part of the smoke dust that is not completely treated by the spray is extracted through the filter hole part 9 on the filter cylinder 4. The smoke dust sequentially passes through the dust extraction pipe 64, the converging pipe 65 and the external pipe 66, and is treated in the dust filter bag through the air extractor. The pressurized water source impact drives the internal gear 56 to rotate, the internal gear 56 drives the rotating rod 55 and the main bevel gear 57 to rotate, the main bevel gear 57 drives the slave bevel gear 513 and the rotating shaft 512 to rotate, the rotating shaft 512 drives the reciprocating wire rod 515 to rotate, the vertical rod 517 moves linearly and reciprocally, the limiting sleeve 514 is used for limiting 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 off the inside of the filter cylinder 4, thereby reducing the adhesion of the material on the filter cylinder 4 and improving the smoke dust extraction effect. With the linear movement of the horizontal column 519, the cleaning rod 63 can adapt to the change of the inside arc of the filter cylinder 4, so that the elastic force of the spring one 523 pulls the sliding rod 524, and the sliding rod 524 always drives the cleaning rod 63 to approach the inside of the filter cylinder 4. The cleaning rod 63 is always closely attached to the inner ring of the filter cylinder 4. The movement of the cleaning rod 63 drives the cleaning roller 610 to move, and the cleaning roller 610 rotates in contact with the filter cylinder 4. The foreign matter on the outside of the cleaning roller 610 is scraped off by the side end face of the mounting groove and falls down. When the hemispherical block 69 moves to the position of the filter hole part 9, the elastic force of the spring two 68 drives the hemispherical block 69 to be clamped into the filter hole part 9 by a small distance, thereby achieving the cleaning effect of the filter hole part 9.
