Acted on being passed to vacuum tank 6 to screen cloth 5, so as to the moisture in drilling fluid mud, pernicious gas and volatile materials
Adsorbed, and desiccation is realized to drilling fluid mud；Vacuum plant is by the moisture in drilling fluid mud, pernicious gas（Deng）And volatile materials（Oil hydrocarbon compound, benzene homologues（Toluene, ethylbenzene, dimethylbenzene）It is adsorbed to
After in vacuum plant, pernicious gas and volatile materials are separated from liquid phase；And carried out through exhaust outlet discharge at burning
Reason；The moisture and the solid phase of part fine particle size adsorbed is circulated through entering subsequent work in tube pump to the collecting pit that flows back；
In the vacuum plant course of work, the drilling fluid mud on screen cloth 5 after drying and other treatment（Filter cake）Before continuing with screen cloth 5
OK, when drilling fluid mud is moved at the position of upper air knife 11, upper air knife 12 starts work, during this, controls upper air knife
11 operating angle controls the wind speed of air knife in 510L/min -1650L/min scopes in 20 ° -45 ° scopes, to reduce brill
The speed of service of well liquid mud, and drilling fluid mud is rolled on screen cloth 5, so as to drilling fluid mud（Filter cake）Carry out again
Purge drying and other treatment；
Drilling fluid mud through drying and other treatment again（Filter cake）Continue to move ahead and drop in collection union in disposable box 28 with screen cloth 5
Middle processing, unloads drilling fluid mud（Filter cake）When screen cloth 5 afterwards is run to the position of lower air knife 12；Lower air knife 12 starts work,
Cleaning treatment is carried out to the mud that is remained in the mesh of screen cloth 5, to ensure the penetrating of the mesh of screen cloth 5, during this, leeward is controlled
The operating angle of knife 12 controls the wind speed of air knife in 510L/min -1650L/min in 5 ° -10 ° scopes；Mesh is cleaned
Screen cloth 5 after processing is rotated further operation, when the screen cloth 5 after cleaning treatment is run to the position of material feeding box 19, material feeding box 19
Interior drilling fluid mud is branched on the screen cloth after cleaning treatment 5 by liquid outlet groove 21；Hence into subsequent work circulation.This shakes
Effective processing to different mud, sludge can be achieved by adjusting the vacuum in vacuum tank 6 in dynamic sieve.By to upper air knife 11
Outlet angle and tolerance regulation, blowback can be carried out for different types of material on screen cloth 5, the desiccation effect of mud is improved
Really, the material for blocking, adhering to and can be cleared up on screen cloth 5 well by lower air knife 12, the cleaning of screen cloth 5 is kept.Bored to reducing
Bits have positive meaning to the pollution of air and the harmfulness of operating environment.
