Technical Field
[0001] The invention relates to the field of dust removal equipment, in particular to a mobile dust remover for industrial plants. Background Art
[0002] There is often a large amount of smoke and dust floating in existing industrial plants, especially in plants engaged in steel structure welding and casting cleaning. There will be a lot of welding smoke and casting dust. Although some plants are partially equipped with dust removal devices, due to the large working area and different working requirements, such as the welding of long and large components such as the assembly and welding of railway vehicles, and the cleaning of heavy and large components, the dust collector solutions for local dust removal cannot take into account the entire working area. One of the reasons is that the lifting of large components requires the running space of the crane, so traditional dust hoods cannot reach the ideal capture area and cannot cover the large-span working area of large plants; it is unrealistic to carry out industrial dust removal in the entire plant, which requires a huge dust collector; and traditional ventilation cannot take into account the middle part of large plants. Summary of the invention
[0003] In order to overcome the deficiency that the existing dust collector cannot cover the entire working area of a large factory building, the present invention provides an industrial factory building crane mobile dust collector. The industrial factory building crane mobile dust collector is combined with the factory building crane to perform mobile dust removal, thereby fully covering the factory building working area and solving the problem of dust removal in large industrial factories.
[0004] The technical solution of the present invention is: a mobile dust collector for industrial plant crane, including a dust removal box, which is fixed on the main beam of the crane through a hoisting assembly, the dust removal box is connected to an air suction duct, the air suction duct is connected to a dust collecting hood, a filter element is provided inside the dust removal box, the bottom of the filter element is connected to a dust collecting hopper, and a fan and an exhaust duct are provided on the upper part of the dust removal box.
[0005] A baffle channel is provided inside the dust removal box, the upper end of the baffle channel is connected to the air suction pipeline, and the lower end is connected to the dust collecting hopper.
[0006] The exhaust duct is connected to an air compressor, the outlet of the air compressor is connected to an air storage cylinder through a filter, and the outlet of the air storage cylinder corresponds to the upper part of the filter element.
[0007] A pulse control valve is provided at the outlet of the air storage cylinder to back-blow and clean the filter element in a pulse manner.
[0008] The bottom of the dust collecting hopper is connected to the dust collecting drawer, and a check valve is arranged between the dust collecting hopper and the dust collecting drawer.
[0009] The air suction pipeline and the dust collecting hood are both located below the main beam of the crane.
[0010] The air compressor is fixed on the upper part of the main beam for crane maintenance.
[0011] The top height of the exhaust duct does not exceed the highest point of the vehicle.
[0012] The present invention has the following beneficial effects: Due to the adoption of the above scheme, the dust collector is fixed on the main beam of the crane as a whole and can move with the crane, so as to achieve mobile dust removal at fixed points wherever there is smoke and dust, thus solving the problem of floating large amounts of smoke and dust in industrial plants and realizing aerial dust removal. In addition, the dust collector is small in size and does not affect the normal operation of the crane or the working sight of the crane driver. The filter element can be replaced and repaired using the existing crane landing platform, and the dust collection drawer of the dust collector can also be cleaned on this platform, which is convenient and quick.

DETAILED DESCRIPTION
[0015] The present invention will be further described below in conjunction with the accompanying drawings: Depend on Figures 1 to 3As shown, a mobile dust collector for industrial plant cranes includes a dust removal box 11, which is fixed to the crane main beam by a hoisting assembly 14. The dust removal box 11 is located on a main beam without a cab, and can be located on the same side of the main beam as the cab. The dust removal box 11 is connected to a suction duct 2, and the bottom of the suction duct 2 is connected to a dust hood 1. The suction duct 2 and the dust hood 1 are located below the crane main beam and do not affect the driving range. The lower edge of the dust hood 1 is ensured to be higher than the working line of sight of the driving driver to avoid affecting the driver's observation during operation. If space permits, the width of the dust hood 1 should cover the span of the plant as much as possible. The dust removal box 11 is provided with a filter element 10 inside. The size and number of the filter element 10 depend on the dust removal requirements of the corresponding factory building. The bottom of the filter element 10 is connected to the dust collecting hopper 5. The dust removal box 11 is provided with a baffle channel 4. The upper end of the baffle channel 4 is connected to the air suction port 3 of the dust removal box 11, which is connected to the air suction pipe 2, and the lower end is connected to the dust collecting hopper 5. The upper part of the dust removal box 11 is provided with a fan 6 and an exhaust port 7, and the exhaust port 7 is connected to the exhaust pipe 13. The top height of the exhaust pipe 13 does not exceed the highest point of the crane. According to the different structural forms of the factory building, the top exhaust type or the opposite side lower exhaust method can be selected. The exhaust pipe 13 occupies a part of the travel of the crane. After installation, the travel limit of the crane needs to be appropriately adjusted to ensure the safe operation of the whole set of equipment.
[0016] After the fan 6 is started, smoke is collected through the dust hood 1, and the air containing smoke enters the dust hopper 5 through the suction pipe 2 and the baffle channel 4. After being filtered by the filter element 10, the clean air enters the upper cavity of the dust removal box 11, and enters the exhaust pipe 13 through the exhaust port 7 through the negative pressure generated by the fan 6, and is discharged into the factory. The dust collector can be moved as a whole with the vehicle and moved to the location where smoke is collected as needed.
[0017] The exhaust pipe 13 is connected to the air compressor 12, and the air compressor 12 can be fixed above the main beam of the driving maintenance for easy maintenance. The outlet of the air compressor 12 is connected to the air storage cylinder 17 through the filter 16, and the outlet of the air storage cylinder 17 corresponds to the upper part of the filter element 10. A pulse control valve 18 is provided at the outlet of the air storage cylinder 17, and the pulse control valve 18 is connected to the board wall connector 15. The bottom of the dust hopper 5 is connected to the dust collection drawer 9, and a check valve 8 is provided between the dust hopper 5 and the dust collection drawer 9. After the air compressor 12 is started, the compressed air generated enters the air storage cylinder 17 through the filter 16, passes through the pulse control valve 18 and the board wall connector 15, and performs back-blowing cleaning treatment on the filter element 10 in a pulse manner. During pulse backblowing, the check valve 8 opens to discharge dust, and during negative pressure exhaust, the check valve 8 is closed. The side of the check valve 8 that contacts the outlet has a rubber layer, which plays the role of dust check. Finally, the dust is collected in the dust collection drawer 9, and the dust collection drawer 9 can be cleaned in time.
[0018] The filter element replacement and dust collector inspection are all done by using the existing landing platform of the driving vehicle. The dust collection drawer of the dust collector is also cleaned on this platform, which is convenient and fast. The dust collector is powered by a bicycle, which is free to move, safe and reliable. This set of dust collectors is small and convenient, moves with the vehicle, and collects smoke and dust efficiently. When using it, the dust collection drawer must be cleaned in time to ensure more efficient completion of the smoke and dust cleaning of large industrial plants. It can solve the dust removal problem of a large amount of floating smoke and dust in existing industrial plants, and realize the capture of dirty air in the air. It is small in size and does not affect the normal operation of the driving, and does not affect the working sight of the driving driver. It realizes the aerial mobile dust removal where dust is generated. The dust collector can be installed on a bridge crane or a single-beam crane. At this time, the dust collector is still attached to the single-beam crane. The dust collector and its pipeline shall not hinder the up and down passage of the vehicle and do not affect the hoisting journey. If it affects the lifting tonnage, you can build a separate beam, place it on the angle wheel, and connect it parallel to the crane. The translational force still comes from the crane.
