Description

TECHNICAL FIELD

[0001] The utility model relates to the field of mortar discharging dust removal, and specifically relates to a dust removal device for mortar raw material discharging port. BACKGROUND

[0002] When the mortar raw material is discharged from the discharging port of the storage tank to the transport vehicle, a large amount of dust will be splashed from the granular or powdery raw material, resulting in serious smoke and dust at the discharging position, affecting the neatness of the processing environment and causing great pollution to the environment. Therefore, a dust suction pipe is usually arranged at the discharging position to reduce the pollution caused by the discharging position. However, the existing dust suction pipe can only perform dust suction treatment on the discharging position, and the dust suction area is small, so that a large amount of dust will still be formed above the vehicle after the raw material falls on the transport vehicle, resulting in that the pollution of the existing discharging port position is still serious, and the neatness of the factory processing environment is affected. SUMMARY

[0003] The utility model discloses a dust removal device for mortar raw material discharging port, which can solve the technical problem of too much smoke and dust during the discharging of mortar raw material, effectively cover the discharging position, reduce the amount of smoke and dust formed by the overflow of the raw material falling on the vehicle, and reduce the pollution to the environment and the influence on the neatness of the factory.

[0006] Further, the baffles are symmetrically arranged on both sides of the fixed frame, and the baffles on both sides always cover below the sliding hole when the fixed frame moves.

[0007] Further, the vertical plate is in sliding contact with the side wall of the sliding hole, and a sliding assembly is arranged between the vertical plate and the top outside of the dust suction cover to drive the fixed frame to slide.

[0008] Furthermore, the sliding assembly includes a sliding motor, an upper gear, and an upper rack. The sliding motor is fixed on the upright plate, the upper gear is fixed on the output shaft of the sliding motor, and the upper rack is fixed on the top of the outer side of the dust collection cover. The upper gear meshes with the upper rack.

[0009] Furthermore, the side of the dust cover is provided with multiple grooves, and the protective plate is slidably connected to the grooves along the vertical direction. The grooves are provided with lifting components that drive the protective plate to slide up and down.

[0010] Furthermore, the lifting assembly includes a lifting motor, a lower gear, and a lower rack. The lifting motor is fixed on the slot plate, the lower gear is fixed on the output shaft of the lifting motor, and the lower rack is fixed on the protective plate. The lower gear meshes with the lower rack, and the slot plate is provided with a clearance groove for use with the lower rack.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. This utility model has a fixed frame fixedly installed on the outside of the material discharge pipe, and the top of the inner side of the dust collection hood is slidably connected to the fixed frame. The top of the fixed frame is provided with a vertical plate, and multiple support wheels are rotatably connected to the vertical plate. The support wheels are in rolling contact with the top of the outer side of the dust collection hood. This structure can use the dust collection hood to cover the material discharge position, preventing dust splashed from the falling raw materials from spilling out and causing pollution. At the same time, the dust collection hood can also slide laterally according to the position of the raw materials falling on the conveyor, so that the dust collection hood always covers the position where the raw materials fall, thereby greatly improving the dust collection effect of the raw materials and reducing the pollution caused by the material discharge position to the factory environment.

[0013] 2. A sliding hole is provided at the top of the dust collection hood. The discharge pipe passes through the sliding hole and connects to the fixed frame. This ensures that when the dust collection hood moves laterally relative to the discharge pipe, the baffles on both sides of the fixed frame can always cover the sliding hole at the top, preventing the dust collection hood from exposing the sliding hole during movement and causing dust to overflow from it. At the same time, multiple protective plates are vertically slidable on the side of the dust collection hood. These protective plates can be adjusted up and down according to the height of the vehicle, forming effective dust protection for the sides of vehicles of different heights, reducing the amount of dust spillage, and further reducing pollution to the factory environment.
