[0062] The present application will be described in detail below in combination with the drawings and specific embodiments.

[0063] The scrap charging mobile dust removal system provided in the embodiments of the present application is a mobile dust removal system, which can further comprise a track 3, a limit switch is arranged on the track 3, and a wheel set 4 cooperating with the track 3 is arranged on the vehicle body frame 6.

[0064] The limit switch on the track 3 is used to accurately control the position where the scrap charging mobile dust removal system is parked, so that the standby position and the working position can be reliably reached each time the mobile switching is performed. Specifically, the number of limit switches can be two, one of which can be located at the standby position, and the other of which can be located at the working position.

[0065] In an embodiment, the docking flow guide part 120 is an open slot with an open cross section gradually decreasing from top to bottom in the height direction. The docking flow guide part 120 can play the role of scrap guiding and dust flow guiding, which can further effectively improve the dust generated during scrap charging.

[0066] The docking flow guide part 120 is an open structure with both ends open, and flow guide plates are arranged around it, which are used for the scrap to fall into the scrap charging trough 1 from the top through the flow guide plates, and play the role of dust collection and guiding during dust removal.

[0067] Specifically, the open slot can include oppositely arranged first and second inclined flow guide plates 121 and 122, and third and fourth inclined flow guide plates 123 and 124 arranged between the first and second inclined flow guide plates 121 and 122, the third and fourth inclined flow guide plates 123 and 124 are arranged along the moving direction of the scrap charging mobile dust removal system as a whole, and the first and second inclined flow guide plates 121 and 122 are arranged along the direction perpendicular to the moving direction of the scrap charging mobile dust removal system as a whole.

[0068] In the embodiments, the scrap charging mobile dust removal system is mainly illustrated as a horizontal moving type, of course, it is not excluded that the track 3 is rotated by 90° from the original horizontal direction to the vertical direction, i.e., the scrap charging mobile dust removal system is changed from the horizontal moving type to the vertical moving type.

[0069] Please refer to Figure 5 , Figure 6 , Figure 7 and Figure 8 , wherein when the docking flow guide part 120 is arranged opposite to the scrap charging trough 1, the bottom of the first and second inclined flow guide plates 121 and 122 is higher than the top of the scrap charging trough 1 by a predetermined distance.

[0070] In the embodiment, when the bottom of the first and second inclined flow guides 121 and 122 is spaced apart from the top of the scrap steel chute 1 by a predetermined distance, the collision between the scrap steel charging and moving dedusting system and the scrap steel chute 1 when the scrap steel charging and moving dedusting system is moving can be avoided. Specifically, the predetermined distance can be about 500 mm, and the application does not limit the value of the predetermined distance.

[0071] Further, when the scrap steel charging and moving dedusting system is located at the working position, the distance between the lowermost ends of the first and second inclined flow guides 121 and 122 is greater than the width of the scrap steel chute 1, and the projection of the first and second inclined flow guides 121 and 122 towards the scrap steel chute 1 forms a predetermined gap with the scrap steel chute 1.

[0072] Since the bottom of the first and second inclined flow guides 121 and 122 is spaced apart from the top of the scrap steel chute 1 by a predetermined distance, in order to ensure that the material can uniformly enter the scrap steel chute 1, the distance between the lowermost ends of the first and second inclined flow guides 121 and 122 can be slightly greater than the width of the scrap steel chute 1, so that the projection of the first and second inclined flow guides 121 and 122 towards the scrap steel chute 1 forms a predetermined gap with the scrap steel chute 1. The value of the predetermined gap is not limited herein. Of course, in some other embodiments, the predetermined gap can be zero or negative due to the adjustment of the predetermined distance.

[0073] Further, the dedusting top cover 7 includes a first part and a second part, and the first part and the second part are located on the two sides of the first and second inclined flow guides 121 and 122, respectively. The dedusting top cover 7 has an inner side wall facing the first and second inclined flow guides 121 and 122, and the inner side wall forms a flow passage communicating the opening slot and the dedusting hole 125 between the first and second inclined flow guides 121 and 122, respectively.

[0074] The scrap steel charging and moving dedusting system further includes a bottom plate connected between the lower ends of the third and fourth inclined flow guides 123 and 124 and the vehicle body frame 6, and the lower ends of the third and fourth inclined flow guides 123 and 124 and the vehicle body frame 6 form a closed structure through the bottom plate.

[0075] When the dust valve 11 on the workshop dust removal pipeline 10 is opened, negative pressure can be generated in the workshop dust removal pipeline 10 and the cover top dust removal pipeline 8 and the dust removal top cover 7 connected with the workshop dust removal pipeline, so as to discharge the dust in the open slot through the flow passage, the dust removal hole 125, the cover top dust removal pipeline 8, and the workshop dust removal pipeline 10. The dust generated by the scrap steel batching can be efficiently and reliably discharged outward according to the direction and path of the flow by means of the above-mentioned negative pressure and the cooperation between the first inclined flow guide plate 121 and the second inclined flow guide plate 122, so that the dust removal effect can be preferably ensured.

[0076] In one specific embodiment, the number of the dust removal holes 125 includes a plurality, and the plurality of dust removal holes 125 are arranged at intervals along the extension direction of the first inclined flow guide plate 121 or the second inclined flow guide plate 122.

[0077] In this embodiment, a plurality of dust removal holes 125 can be arranged on the top wall of any one of the dust removal top covers 7, and the plurality of dust removal holes 125 are arranged at intervals along the extension direction of the first inclined flow guide plate 121 or the second inclined flow guide plate 122, which is beneficial to generating uniform suction force in the length direction of the open slot (i.e. the extension direction of the first inclined flow guide plate 121 or the second inclined flow guide plate 122), so as to uniformly and comprehensively suck the dust in the open slot into the cover top dust removal pipeline 8.

[0078] The number of the dust removal holes 125 can be determined comprehensively according to the size of the dust removal top cover 7, the size of the negative pressure, etc., for example, it can be 3 or the like, and the present application does not make a unique numerical limitation here.

[0079] The dust removal hole 125 and the cover top dust removal pipeline 8 can be connected through the connecting pipeline 9, and specifically, the number of the connecting pipeline 9 matches the number of the dust removal holes 125.

[0080] In one embodiment, the cover top dust removal pipeline 8 is two, and the two cover top dust removal pipelines 8 are respectively arranged on the top wall of the first part and the second part of the dust removal top cover 7, one end of the two cover top dust removal pipelines 8 is a closed end, and the other end is combined to be connected with the workshop dust removal pipeline 10.

[0081] In this embodiment, in order to save cost and simplify the structure, the two cover top dust removal pipelines 8 can be combined and connected with the same workshop dust removal pipeline 10. Specifically, the two cover top dust removal pipelines 8 can be connected through a three-way joint, or the two cover top dust removal pipelines 8 can be an integral structure.

[0082] It should be noted that in the description of the present application, the terms "first", "second" and the like are used only for descriptive purposes and to distinguish similar objects, and there is no precedence between them, nor can it be understood as indicating or implying relative importance.
