Detailed Description
The technical solution of the present invention will be described in further detail through the following embodiments.
As shown in fig. 1-4, a dust collecting device for drilling fluid production comprises a housing 1, wherein an air inlet and an air outlet 4 are arranged on the housing 1, and the air inlet and the air outlet 4 are separated by arranging a dust filtering component 5; the air inlet is positioned on one side of the lower part of the shell 1; the air outlet 4 is positioned at the top of the shell 1; the bottom of casing 1 sets up the dirt fill that falls, the air inlet is connected with admission line 6, the side of going up of intake pipe evenly sets up a plurality of air outlets 9, the downside of intake pipe evenly sets up a plurality of ash falling mouths 8, evenly arrange a plurality of fins 3 in the admission line 6. Specifically, the dust filter assembly may adopt a dust filter structure common in the prior art, for example: and (5) filtering the bags.
