Description

Technical Field

[0001] The utility model relates to the technical field of dust removal equipment, in particular to a dry mortar dust recovery device. Background Art

[0002] There are many steps in the dry mortar production process that generate a large amount of dust, such as sand and gravel screening, powder storage and transportation, raw material mixing, finished product metering and packaging, and related equipment in other steps will generate dust, which puts higher requirements on the dust removal device.

[0003] There are generally two types of dust removal devices for existing dry mortar. One is to set up a separate dust removal device near the equipment in each step that requires dust removal. This type of device can flexibly open the dust removal device in each step to save energy, and the recovered dust can be reused in related steps. The other type is to set up a central dust removal device, and use vacuum pipes to connect the equipment related to each step for dust removal. This type of device has a good dust removal effect, so that the production workshop can meet higher environmental protection requirements.

[0004] However, both types of dust removal equipment will gradually accumulate dust in the dust collection duct due to the corners and diameter changes on the dust collection duct. When the dust accumulates to a certain extent in the dust collection duct, it will seriously affect the dust collection capacity of the dust removal equipment. When the dust collection duct is seriously blocked, the duct needs to be disassembled for cleaning, which seriously affects production efficiency. Utility Model Content
