Abstract

The invention discloses a tube curtain-wet type gradually-changed-density fiber grid composite dust remover for a development machine, and belongs to the technical field of dust removers. The tube curtain-wet type gradually-changed-density fiber grid composite dust remover comprises a box body, wherein a tube curtain, a gradually-changed-density fiber grid and a maze are arranged in the box body, wherein a spray pipe provided with a water-fog spray head is arranged between the tube curtain and the gradually-changed-density fiber grid; the other end of the gradually-changed-density fiber grid is connected with one end of the maze, and the other end of the maze is connected with a blower through a reducing pipe; a dry ash bin, a sludge bin of the gradually-changed-density fiber grid, a sludge bin of the maze and a circulating water tank are arranged at the lower end of the box body; the dry ash bin is connected with the bottom of the tube curtain; the sludge bins are connected with the bottom of the gradually-changed-density fiber grid; a filter is arranged in the circulating water tank; the circulating water tank is connected with the spray pipe through a water pump; and the density of each layer of fence-shaped textile of the gradually-changed-density fiber grid is gradually changed from sparseness to compactness.

Description

technical field [0001] The invention belongs to the technical field of dust collectors, and in particular relates to a composite dust collector of pipe screen-wet density gradient fiber grid for roadheaders. Background technique [0002] Tunnel rock drilling operations and mine underground rock drilling operations all produce a large amount of dust, which will not only cause great harm to the health of the operators, but also affect the life of the roadheader, so ventilation and dust removal must be carried out. Since these places are all narrow and limited spaces, the volume of dust removal equipment is strictly required; since the purified air is discharged in the working space, the dust removal equipment is required to be efficient and low-resistance. Considering safety issues in coal mines, the equipment must be fire-proof and explosion-proof; there is often water in the underground, and excessive humidity can easily cause the bags of the bag filter to stick, making it d...
