In the description of the present invention, it is to be understood that the terms "center", "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", and the like, indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplicity of description, and do not indicate or imply that the device or element being referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore, should not be construed as limiting the present invention. In the description of the present invention, "a plurality" means two or more unless otherwise specified.
Referring to fig. 1 and 2, fig. 1 is a schematic view of a gas-collecting channel structure of a filter press; fig. 2 is a schematic side view of the active cover. The gas collecting hood of the filter press comprises a ventilation pipe 20 and a combined gas collecting hood 30. The combined gas-collecting hood 30 is in a shell shape, is sleeved outside the filter press 10 needing to be gas-collected when in use, and is internally sealed; one end of the ventilation pipe 20 is communicated with the inside of the combined gas collecting hood 30, and the other end is communicated with a waste gas treatment device.
The combined gas-collecting hood 30 comprises a fixed hood, a movable hood 32, a roller 33, a track 34, a handle 35 and a sealing plate 36. The fixed covers comprise a first fixed cover 31a and a second fixed cover 31e which are respectively and fixedly arranged at two ends of the filter press 10; the movable cover 32 comprises a first movable cover 32b, a second movable cover 32c and a third movable cover 32d, the three movable covers 32 are sequentially arranged between the first fixed cover 31a and the second fixed cover 31e, the sizes of the three movable covers are sequentially reduced, the second movable cover 32c can be sleeved in the first movable cover 32b, and the third movable cover 32d can be sleeved in the second movable cover 32 c; the fixed cover and the movable cover 32 are sequentially connected end to end in the sequence of a first fixed cover 31a, a first movable cover 32b, a second movable cover 32c, a third movable cover 32d and a second fixed cover 31 e; the pulley 33 is arranged below each movable cover 32, the rail 34 is arranged between the two fixed covers, and the pulley 33 is matched, so that the movable covers 32 can slide between the two fixed covers along the rail 34; the handle 35 is arranged on the side of each movable hood 32 parallel to the rail 34; the sealing plates 36 are disposed on the sides of the two ends of the fixed cover away from the movable cover 32 to enhance sealing.
