In order to ensure the sealing performance of the dust hood, first sealing mechanisms are arranged between two sides of the movable hood and the side wall 1 of the hood body, and second sealing mechanisms are arranged between adjacent movable hoods and between the movable hood and the fixed hood 2. Specifically, the first sealing mechanism includes a horizontal baffle plate 41 welded on the inner side of the cover body sidewall 1, and arc-shaped elastic steel plates 42 (which may be coated with a rubber layer) installed on both sides of the moving cover, wherein the arc-shaped elastic steel plates 42 are located above the horizontal baffle plate 41 and have opposite contact surfaces, and the moving cover moves, so that the sliding seal can be maintained between the two. Similarly, the arc-shaped elastic steel plates 42 of the first moving cover 31, the second moving cover 32 and the third moving cover 33 are sequentially stacked from inside to outside to ensure the sealing performance between the moving covers. Meanwhile, the sealing between the top surfaces of the adjacent moving covers and between the moving cover and the top surface of the fixed cover 2 is realized by a second sealing mechanism which comprises cambered elastic steel plates 43 (a rubber layer can be coated on the surface) respectively arranged at the front ends of the second moving cover 32, the third moving cover 33 and the fixed cover 2, and each cambered elastic steel plate 43 is lapped on the moving cover at the front side thereof, so that the sealing of the transverse connection position is realized. In addition, a flexible drape 44 is attached to the front end of the first movable hood 31 at the foremost end to form a hood seal.
In order to realize the air exhaust in the cover, a transverse exhaust duct is arranged at the top of the movable cover and the fixed cover 2. Specifically, the first transverse exhaust duct 51 is respectively installed at the front ends of the second movable hood 32 and the third movable hood 33, the second transverse exhaust duct 52 is respectively installed at the front end and the rear end of the fixed hood 2, and a plurality of vent holes are uniformly distributed on the bottoms of the first transverse exhaust duct 51 and the second transverse exhaust duct 52 and the top surface of the hood body corresponding to the bottom of the first transverse exhaust duct 51 and the second transverse exhaust duct 52, so that the air flow in the hood can smoothly enter the transverse exhaust ducts. Each transverse exhaust pipe is provided with a dust removal unit in a matching way, and each dust removal unit comprises a ventilator 61, a dust remover 62 and an exhaust chimney 63 which are sequentially connected with the transverse exhaust pipe through pipelines. In the embodiment, in order to save investment, two adjacent sets of dust removing units share one exhaust chimney 63, so that two exhaust chimneys 63 are provided in total. In practical applications, the first horizontal exhaust duct 51 and the second horizontal exhaust duct 52 may be arranged in a row along the longitudinal direction, or may be formed by a single vertical duct with a partition therein.
Since the first cross exhaust duct 51 can move with the moving cover, a sliding sealing duct mechanism is provided between the first cross exhaust duct and the corresponding dust removing unit. Specifically, the sliding sealing pipe mechanism comprises a longitudinal exhaust pipe 71 arranged at the inlet end of the dust removal unit, wherein a longitudinal through groove is formed in the top surface of the longitudinal exhaust pipe 71, and a sealing belt 72 adsorbed by negative pressure is arranged on the longitudinal through groove; the sliding sealing pipe mechanism further comprises a movable air pipe joint arranged at the end part of the first transverse exhaust pipe 51, and the movable air pipe joint comprises a pipe joint 73 communicated with the first transverse exhaust pipe 51 and a sealing cover 74 arranged on the outer side of the pipe joint 73; wherein, the pipe joint 73 is positioned between the sealing belt 72 and the longitudinal exhaust pipe 71, and the lower opening of the pipe joint 73 corresponds to the longitudinal through groove; the sealing cover 74 is located outside the sealing belt 72, and the lower opening of the sealing cover 74 is in sealing contact with the sealing belt 72. Further, a pair of upper roller shafts 75 and a pair of lower roller shafts 76 are provided between the pipe joint 73 and the sealing cover 74, wherein the upper roller shafts 75 are positioned below the sealing belt 72, and the lower roller shafts 76 are positioned above the sealing belt 72 for forming a movable airtight connection with the sealing belt 72. The lower opening of the pipe joint 73 is always communicated with the longitudinal exhaust pipe 71, and the sealing belt 72 on the outer side of the pipe joint can keep the longitudinal through groove of the longitudinal exhaust pipe 71 in a sealing state when the pipe joint is adsorbed by negative pressure, so that smooth smoke discharge of the first transverse exhaust pipe 51 can be realized when the movable cover moves.
Interlocking control is arranged between the movable cover and the dust removal unit, namely when the movable cover moves, the corresponding ventilator 61 stops running; when the mobile cowling is moved into position, the corresponding ventilator 61 is switched on.
When a large amount of smoke and dust are generated in a working area and need to be collected, the first movable cover 31, the second movable cover 32 and the third movable cover 33 are pulled out of the fixed cover 2, even if the top cover of the cover body is completely unfolded to cover the operating area, and simultaneously, a blower connected with the air supply outlet 11 and a ventilator 61 in each set of dust removal unit are started to form ordered airflow in the cover; the dust-containing flue gas in the cover body top cover is collected by the nearest transverse exhaust pipe in sections and then is sent to the corresponding dust removal unit for purification and standard emission. For example, the air flow in the first moving hood 31 flows backwards from the front end, and when reaching the first transverse exhaust duct 51 at the front end of the second moving hood 32, is captured by the first transverse exhaust duct and sent to the corresponding dust removing unit through the pipe joint 73 and the longitudinal exhaust duct 71, and is discharged after being purified and reaching the standard. The smoke generated in the operation of the operation area can be collected by the corresponding air outlet nearby, so that the pollution of the smoke generated in the operation of the outer end area to the inner operation area can be reduced to the maximum extent.
When hoisting operation such as travelling is required, the ventilator 61 stops working, and different numbers of movable covers are selected according to the size of a hoisting area to be contracted into adjacent movable covers or fixed covers. After the collection cover is moved in place, the ventilator 61 corresponding to the superposed movable cover stops working, other fans work normally, at the moment, the crane works, and meanwhile, the lower part of the collection cover can also perform normal smoke exhaust purification process operation.
It should be noted that in the description of the present invention, terms of orientation or positional relationship such as "front", "rear", "left", "right", "vertical", "horizontal", "inner", "outer", etc., are based on the orientation or positional relationship shown in the drawings, and are only for convenience of description and simplification of description, but do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus, should not be construed as limiting the present invention.
