Dust collection hopper structure used for ship unloader

Abstract

The invention relates to a dust collection hopper structure used for a ship unloader. The dust collection hopper structure used for the ship unloader comprises a hopper, wherein a rectangular wind shield wall which is formed by four wind shield wall bodies is connected to the upper portion of the hopper, dust collection ports which are connected with dust collection equipment are symmetrically formed in each wind shield wall body, a plurality of supporting rib plates are connected to the inner wall of each wind shield wall body, the upper edge of each supporting rib plate is connected to a first steel plate, the lateral side of each supporting rib plate is connected to a second steel plate, an inverted-U-shaped cavity with an opening facing downwards is formed by the first steel plates, the second steel plates, the supporting rib plates and the inner walls of the wind shield wall bodies, and a distribution grating is installed in the hopper and is located on the lower portion of the inverted-U-shaped cavity. According to the dust collection hopper structure used for the ship unloader, due to the fact that the dust collection holes are symmetrically formed in each wind shield wall body and the inverted-U-shaped cavity which is provided with the opening facing downwards and is formed by connection of the supporting rib plates and the steel plates, dust flying along the wall of the hopper and the wind shield wall bodies can be well collected and circulates in the supporting rib plates with kidney-shaped holes, the dust is prevented from overflowing again, the dust collection effect is greatly improved, and dust collection efficiency is improved.

Description

technical field [0001] The invention relates to dust removal equipment, in particular to a dust collecting port structure for a ship unloader. Background technique [0002] With the development of my country's economy and the rapid progress of port construction, the demand for ship unloaders is increasing. In order to protect the environment, a dust removal device must be used at the hopper of the ship unloader to clear the dust generated during unloading. At present, the dust removal equipment of ship unloader adopts water spray dust removal and negative pressure dust removal. The way of water dust removal is easy to make the cohesiveness of the material strengthen after contact with water, resulting in material blockage at the outlet of the hopper. [0003] The installation structure of negative pressure dust removal is to install a fan and dust collection box outside the hopper, and open a dust collection port on the hopper wall or windshield wall to suck in dust and re...

AI Technical Summary

Problems solved by technology

At present, the dust removal equipment of the ship unloader adopts water spray dust removal and negative pressure dust removal. The installation structure of the water spray dust removal is to install nozzles around the windshield wall of the hopper, and spray water mist through the nozzles to suppress the dust from overflowing the hopper. The way of water dust removal is easy to make the cohesiveness of the material strengthen after contact with water, resulting in blockage at the outlet of the hopper

[0003] The installation structure of negative pressure dust removal is to install a fan and a dust collection box outside the hopper, and open a dust collection port on the hopper wall or windshield wall to suck in dust and recover resources. Unsatisfactory dust collection effect due to too large opening and too fast dust raising speed
