Description

Technical Field

[0001] The utility model relates to the technical field of bag dust collectors, in particular to a bag dust collector discharging device. Background Art

[0002] The bag filter is a dry dust filter. It is suitable for capturing fine, dry, non-fibrous dust. The filter bag is made of textile filter cloth or non-textile felt. The filter fabric is used to filter the dust-containing gas. After the dust-containing gas enters the bag filter, the large particles and heavy dust settle down due to gravity and fall into the ash hopper. When the gas containing finer dust passes through the filter material, the dust is retained, so that the gas is purified.

[0003] The publication number is CN201719942U, and the name is a bag dust collector discharging device including a machine trough, a feed port, a reamer, and a discharge port. The machine trough is "U"-shaped, and the reamer is horizontally arranged in the machine trough. The discharge port is located below the middle section of the reamer and is opened at the bottom of the machine trough. The feed port is a threaded groove formed by the spiral blades of the reamer, wherein a cover plate is arranged above the middle section of the reamer body, and both sides of the cover plate are tightly connected to the machine trough. The spiral blades of the reamer extend into the inside of the cover plate. When the material is continuously pushed toward the discharge port by the spiral blades, a part of it will accumulate near the discharge port. The continuously accumulated material and the cover plate together block the discharge port, so that the negative pressure inside the bag dust collector can be guaranteed. The reamer with its own short seal realizes the material discharge and the air-proof effect of closing and isolating the dust collector from the system.

[0004] However, when the dust is discharged by means of a reamer in the discharge barrel, there is a gap between the reamers during the reaming process, and some air is carried out with the reamer during the ash discharge, which causes a change in the pressure in the shell of the bag filter. The discharge of ash affects the constant pressure of the shell of the bag filter, and affects the dust removal work of the bag filter at a later stage. Utility Model Content
