Dust discharging and collecting integrated device

Abstract

The invention discloses a dust discharging and collecting integrated device in the field of dust removing equipment. The dust discharging and collecting integrated device comprises a telescopic innersleeve, a telescopic outer sleeve and a dust hood, an unloading inlet is formed in the upper end of the telescopic inner sleeve, the lower end of the telescopic inner sleeve is connected with the dusthood, the telescopic outer sleeve is arranged outside the telescopic inner sleeve in a covering mode, the upper end of the telescopic outer sleeve is connected with the telescopic inner sleeve in a sealed mode, and the lower end of the telescopic outer sleeve is communicated with the dust hood, a vent pipe is arranged at the upper end of the telescopic outer sleeve pipe and is connected to a dustremoval pipe network or is pressed and returned by a dust removal fan to return to a dust bin. The dust discharging and collecting integrated device has the advantages that the telescopic inner sleeve and the telescopic outer sleeve are arranged, the distance between the dust hood and the carriage can be adjusted during unloading, secondary flying dust can be reduced, the dust catching channel isformed through the telescopic outer sleeve, so that secondary flying dust is further reduced, the storage bin is small in energy consumption, no dust is generated, the influence of wind force is avoided, the environment pollution of the ash discharging post is avoided.

Description

Technical field [0001] The invention relates to the field of dust removal equipment, in particular to an integrated device for dust unloading and collecting. Background technique [0002] The ash storage bin is usually used in the dust removal system to store the dust collected by the dust collector. In addition to pneumatic conveying and belt conveying, the ash unloading process usually adopts the following two forms. The first one is: ash storage → ash discharge valve → slide pipe, dust hood → ash truck. The disadvantage is that the system energy consumption is high, and the dust hood needs to be designed to connect the air duct and the dust removal pipe for capturing The dust generated during the ash unloading process usually consumes 20000m of air in the dust removal system 3 / h, or even greater; the secondary dust is large and the dust capturing ability is poor. Due to the gap between the dust hood and the ash truck compartment, when the material falls into the compartment,...

AI Technical Summary

Problems solved by technology

The first one is: ash storage bin → ash unloading valve → slide pipe, vacuum hood → ash truck. The dust generated during the ash unloading process usually consumes an air volume of 20,000m in the dust removal system 3 About / h, or even larger; the secondary dust is large and the dust capture ability is poor. Due to the gap between the dust collection hood and the carriage of the ash truck, when the material falls to the carriage, a large amount of secondary dust will overflow. Under windy conditions , the effect is worse

The second type is: ash storage bin → ash unloading valve → dust humidifier → chute → ash truck. The disadvantages are: high energy consumption for equipment operation, the power of the drive motor of the dust humidifier is ~15kw, and the water consumption is about 15t / h; The energy consumption of automobile transportation, after the material is humidified, the specific gravity of the material is increased; it is not suitable for dusty materials and hydrophobic materials that do not need to be humidified in the next process
