Problems solved by technology

At present, the filter dust recovery device includes a filter bag to collect dust. This bag filter has a short service life, needs to be replaced frequently, and is inconvenient to use and maintain. Moreover, the filter capacity of the filter bag filter is limited and cannot meet For the purpose of high-efficiency filtration and recovery of dust, if a large amount of dust recovery is to be achieved, it is necessary to increase equipment investment, which will increase production costs

Abstract

The invention discloses a dust recovery system. The system comprises a shell with an air inlet and an air outlet, and is characterized in that a separator for separating an inner cavity of the shell into an upper cavity and a lower cavity is arranged in the shell; at least two cartridge filters are arranged in the cavity above the separator; the inner cavity of each cartridge filter is communicated with the lower cavity; one side of the lower cavity is communicated with an external exhaust fan through the air outlet; the upper cavity is connected with a dust recovery pipeline of a spray chamber through an air inlet formed in the upper part of the shell; the cavity communicated with the lower part of the cartridge filters and the cavity in the inner side of the air outlet in the shell are separated into two spaces by a separator in the lower cavity; a filtering channel with a gauze filter is formed in the separator; and a powder outlet with a door is formed in the side of the shell above the separator. The dust recovery system disclosed by the invention has the characteristics of reasonable and compact structure, convenience and reliability in use, long service life, convenience in maintenance, capacities of increasing the filtering capacity according to actual needs, reducing the equipment investment and reducing the increased production cost, high dust filtering and recovering efficiency, and the like.

Description

technical field [0001] The invention relates to a filter-type high-efficiency dust recovery system, in particular to a system suitable for dust recovery on coating equipment spraying powder coating equipment, and belongs to the technical field of dust purification. Background technique [0002] Existing dust recovery devices mainly include cyclone separation and filtration. Cyclone separation is mostly used for coarse separation and recovery of dust with large particles, while filtration separation and recovery is mostly used for fine separation and recovery. Therefore, filtration separation and recovery is mainly used for secondary separation and recovery. At present, the filter dust recovery device includes a filter bag to collect dust. This bag filter has a short service life, needs to be replaced frequently, and is inconvenient to use and maintain. Moreover, the filter capacity of the filter bag filter is limited and cannot meet For the purpose of high-efficiency filtra...
