TECHNICAL FIELD
[0001] The present application relates to the technical field of industrial environmental protection equipment, more particularly to a crane with air pollutant collecting and processing functions. BACKGROUND
[0002] In the traditional industrial workshop environment, there are often air pollutants such as welding fumes and dust. The crane, as the core material handling equipment, is prone to exacerbate the diffusion of air pollutants during operation due to factors such as mechanical friction, cargo lifting and lowering, and environmental airflow disturbance, resulting in the accumulation of dust particles, harmful gases and other pollutants, which seriously threatens the health of workers and accelerates the corrosion of equipment. The existing crane technology only focuses on the cargo lifting function and lacks the ability to actively intervene in the air quality of the working area. The conventional dust removal equipment is difficult to adapt to the dynamic operation characteristics of the crane due to its fixed installation position and limited coverage, resulting in low efficiency of pollutant treatment. Therefore, there is an urgent need for a crane that integrates air pollutant collecting and processing functions to achieve dynamic capture and efficient purification of polluted gases while completing material handling.

[0014] Please see Figures 1-10 In this embodiment of the invention, a crane with the function of collecting and treating air pollutants includes: Support cable tray 1 is installed inside the workshop; End beam 2 is mounted on the two side support bridges 1 via wheel movement; Two main beams 3 are symmetrically distributed, with their ends fixed to the two end beams 2 on both sides respectively; The lifting trolley 4 is mounted on the main beam 3; The movable connecting frame 5 is provided in two sets corresponding to the main beam 3. Each set has two sets symmetrically distributed about the main beam 3 and is movable on the outside of the main beam 3. The movable connecting frame 5 is equipped with a rotating connecting assembly 6 and a vibration device 7; The collection and processing device 8 is fixed on the rotating connection assembly 6.
[0015] In this embodiment, the end beam 2 is provided with a sedimentation collection chamber 21, and the two ends of the sedimentation collection chamber 21 correspond to the two ends of the main beam 3.
[0016] In other words, when the crane lifts or lowers the goods, the rotating connection assembly 6 rotates the other end of the collection and processing device 8 to the end beam 2, connecting it to the collection and sedimentation chamber 21. The vibration device 7 shakes off the dust particles attached to the collection and processing device 8, cleaning the collection and processing device 8, maintaining its processing efficiency, and extending its service life.
[0017] In this embodiment, the main beam 3 is provided with a track 31 on the outer side and connecting grooves 32 at both ends on the outer side. The connecting grooves 32 correspond to one end of the collection and processing device 8 and are connected to the collection sedimentation chamber 21.
[0018] In other words, when the crane is stationary or moving, the movable connecting frame 5 drives the collection and treatment device 8 to move on the track 31 of the main beam 3, and the rotating connecting assembly 6 drives the collection and treatment device 8 to rotate at multiple angles to collect and treat the air containing pollutants.
[0019] In this embodiment, the rotating connection assembly 6 includes: The connecting base 61 is fixed on the movable connecting frame 5; Rotating component 62 is rotatably mounted on connecting base 61; Two adjusting arms 63 are symmetrically distributed and fixed at both ends of the rotating part 62. The adjusting arms 63 are provided with a rotating connecting shaft, which is fixedly connected to the collection and processing device 8.
[0020] In other words, the rotating component 62 rotates on the connecting base 61, causing the adjusting arm 63 and the collection and processing device 8 to rotate around the center of the connecting base 61. The collecting and processing device 8 is driven to rotate around the shaft of the connecting shaft via the connecting shaft on the adjusting arm 63, so that the collecting and processing device 8 can fully cover the area around the crane and accurately collect polluted gas.
[0021] In this embodiment, the vibration device 7 includes: Universal connector 71 is fixed on the movable connector 5 and located on one side of the rotating connector 6; The vibrating column 72 is fixed at the bottom to the universal connector 71 and has an arc-shaped top, which corresponds to the collection and processing device 8. Inside, there is a vibrating motor that fits into the arc-shaped top surface. Multiple elastic support members 73 are arranged in a ring, and their two ends are fixedly connected to the outer walls of the movable connecting frame 5 and the vibrating column 72, respectively.
[0022] In other words, when the rotating connecting assembly 6 drives the collection and processing device 8 to rotate, connecting the collection and processing device 8 with the collection and sedimentation chamber 21 to clean the attached dust, the collection and processing device 8 is in an inclined state. Under the action of the collection and processing device 8, the vibrating column 72 deflects through the universal connecting seat 71, so that the vibrating column 72 is in contact with the collection and processing device 8, and is supported by the elastic support member 73. Under the action of the vibration motor, the collection and processing device 8 is continuously vibrated, promoting the removal of the attached dust and conveying it to the collection and sedimentation chamber 21. A soft rubber ring is provided at the connection between the collection and sedimentation chamber 21 and the collection and processing device 8, so that the collection and processing device 8 and the collection and sedimentation chamber 21 maintain a sealed connection under the action of vibration to prevent dust leakage.
[0023] In this embodiment, the collection and processing device 8 includes: Adjustment component 81 is fixedly connected to rotational connection component 6; The sealed housing 82 is fixed to the outside of the adjusting assembly 81; The secondary filter assembly 83 is movably positioned in the middle of the adjustment assembly 81; The primary filter assembly 84 is movably disposed in the middle of the secondary filter assembly 83, and one end located outside the sealed housing 82 is connected to the exhaust port 85.
[0024] In other words, under the action of the sealed outer shell 82, the gas flow between the regulating component 81, the secondary filter component 83 and the primary filter component 84 is kept in a sealed space to prevent the leakage of polluted gas and incomplete cleaning. By moving the primary filter component 84 within the secondary filter component 83 and the secondary filter component 83 within the regulating component 81, the length of the collection and treatment device 8 is dynamically adjusted to cover a large area around the crane and collect and treat polluted gas at specific points.
[0025] In this embodiment, the adjustment component 81 includes: Two three-stage conveyor arms 811 are symmetrically distributed vertically and are fixedly connected to the rotating connection assembly 6 via a sealed housing 82. The outer limit block 812 is fixed between the three-stage conveyor arms 811; The third-stage sealing plate 813 is fixed on the outside of the third-stage conveyor arm 811; The exhaust surface 814 is fixed to one end of the third-stage sealing plate 813 near the rotating connection assembly 6; The third-level positioning plate 815 is fixed on the inner side of the third-level conveying arm 811, at the end away from the outer limit block 812. The vacuum motor 816 is fixed inside the three-stage conveyor arm 811 and corresponds to the exhaust surface 814.
[0026] In other words, under the action of the vacuum motor 816, polluted gas is drawn into the primary filter component 84 through the exhaust port 85. After being filtered by the primary filter component 84, it enters the secondary filter component 83 for secondary filtration. The primary filter component 84 mainly uses a HEPA filter to remove dust and other particles, while the secondary filter component 83 mainly uses activated carbon adsorption to remove gaseous pollutants. The filtered and purified gas enters the tertiary conveying arm 811 through the spacer between the outer limit block 812 and the tertiary positioning plate 815, and is then discharged through the exhaust surface 814 on the side of the vacuum motor 816.
[0027] In this embodiment, the secondary filtration component 83 includes: Two secondary conveying arms 831 are symmetrically distributed vertically and are movably positioned inside the tertiary conveying arm 811. A secondary filter channel 8311 is provided at one end corresponding to the outer limiting block 812. The inner limit block 832 is fixed between the secondary conveyor arms 831; The secondary sealing plate 833 is fixed on the outside of the secondary conveying arm 831 and fits against the tertiary positioning plate 815; The secondary filter surface 834 is located on the same side as the secondary sealing plate 833 and corresponds to the interval channel between the outer limiting block 812 and the tertiary positioning plate 815. The secondary positioning plate 835 is fixed on the inner side of the secondary conveying arm 831, at the end away from the inner limit block 832.
[0028] In other words, polluted gas is drawn into the primary filter assembly 84 through the exhaust port 85. After being filtered by the primary filter assembly 84 and having dust and other particles removed, the preliminarily purified air enters the secondary conveying arm 831 through the spacer between the secondary positioning plate 835 and the inner limit block 832. Then, it is purified by the secondary filter surface 834 and the secondary filter channel 8311 to remove gaseous pollutants before entering the tertiary conveying arm 811 and finally being discharged through the exhaust surface 814.
[0029] In this embodiment, the primary filter component 84 includes: The primary conveying arm 841 is movably positioned between the secondary conveying arms 831, and one end corresponding to the inner limit block 832 is provided with a primary filter channel 8411, while the other end is fixed with a drain port 85. The primary sealing plate 842 is fixed to the side of the primary conveying arm 841 and fits against the secondary positioning plate 835; The primary filter surface 843 is fixed to the side of the primary conveying arm 841, connected to the primary sealing plate 842, and corresponds to the interval channel between the secondary positioning plate 835 and the inner limiting block 832.
[0030] In other words, the exhaust port 85 draws the polluted gas into the first-stage conveying arm 841, where it is filtered by the first-stage filter surface 843 and the first-stage filter channel 8411 to remove dust and other particles. The gas then enters the second-stage conveying arm 831, where gaseous pollutants are removed, and the gas is conveyed to the third-stage conveying arm 811. Finally, the gas is discharged through the exhaust surface 814.
[0031] In a preferred embodiment, the length of the primary filter surface 843 on the side of the primary filter assembly 84 and the movable distance of the primary filter assembly 84 are both less than the length of the gap channel between the inner limiting block 832 and the secondary positioning plate 835 on the secondary filter assembly 84. Similarly, the length of the secondary filter surface 834 in the secondary filter assembly 83 and the movable distance of the secondary filter assembly 83 are both less than the length of the gap channel between the outer limiting block 812 and the tertiary positioning plate 815 on the adjusting assembly 81. That is, when the primary filter assembly 84 and the secondary filter assembly 83 extend sequentially to collect polluted gas at a fixed point, a portion of the primary filter surface 843 is always connected to the gap channel between the inner limiting block 832 and the secondary positioning plate 835 on the secondary filter assembly 83, and a portion of the secondary filter surface 834 is always connected to the gap channel between the outer limiting block 812 and the tertiary positioning plate 815 on the adjusting assembly 81, thus maintaining the gas flow within the filter assembly. The airflow between the filter components is rapid. When the vacuum motor 816 reverses and the airflow backflushes to clean the filter surface, the primary filter component 84 and the secondary filter component 83 move sequentially, connecting the exhaust port 85 to the sedimentation collection chamber 21. This ensures that the primary filter surface 843 is always aligned with the spaced channel between the inner limiting block 832 and the secondary positioning plate 835 on the secondary filter component 83. Furthermore, the primary filter channel 8411 disengages from the inner limiting block 832, allowing both the primary filter channel 8411 and the primary filter surface 843 to be impacted by the reverse airflow for cleaning. Similarly, the secondary filter surface 834 is always aligned with the spaced channel between the outer limiting block 812 and the tertiary positioning plate 815 on the adjusting component 81, and the secondary filter channel 8311 disengages from the outer limiting block 812, allowing both the secondary filter channel 8311 and the secondary filter surface 834 to be impacted by the airflow for cleaning.
[0032] In specific implementation, firstly, when the crane is stationary or moving, the movable connecting frame 5 drives the collection and processing device 8 to move on the track 31 of the main beam 3, and the rotating connecting assembly 6 drives the collection and processing device 8 to rotate at multiple angles. The primary filter assembly 84 and the secondary filter assembly 83 in the collection and processing device 8 extend sequentially to collect and process polluted gas at specific locations. The exhaust port 85 draws the polluted gas into the primary conveying arm 841, where it is filtered by the primary filter surface 843 and the primary filter channel 8411 to remove dust and other particles. Then, it enters the secondary conveying arm 831 through the spaced channel between the inner limit block 832 and the secondary positioning plate 835, where it is purified by the secondary filter surface 834 and the secondary filter channel 8311 to remove gaseous pollutants. Finally, it enters the tertiary conveying arm 811 through the spaced channel between the outer limit block 812 and the tertiary positioning plate 815, and is discharged through the exhaust surface 814. When the crane lifts or... When lowered, the filter components at each stage in the collection and processing device 8 are reset, the movable connecting frame 5 is reset, and the other end of the collection and processing device 8 is rotated to the end beam 2 by the rotating connecting component 6, so that the primary filter component 83 and the secondary filter component 83 are partially extended, pushing the exhaust port 85 to connect with the collection and sedimentation chamber 21. At the same time, the dust suction motor 816 reverses, so that the collection and processing device 8 changes from the suction mode to the blowing mode. The airflow enters the tertiary conveying arm 811 from the exhaust surface 814, and after impacting the secondary filter surface 834 and the secondary filter channel 8311 in the reverse direction, the airflow enters the secondary conveying arm 831, and then back-impacts the primary filter surface 843 and the primary filter channel 8411. The vibration device 7 applies continuous vibration to the collection and processing device 8, shaking off the dust and other particles attached to the filter components, and under the drive of the airflow, they are discharged into the collection and sedimentation chamber 21, realizing real-time cleaning of the filter material, ensuring continuous and efficient operation of the equipment, and extending its service life.
[0033] The above description is merely a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
