The technical solution adopted in the utility model is: the airtight vibrosieve of oil drilling, mainly form by discharge opeing slush pump, collecting tank, Level meter, closed shell, vibrosieve, spiral Scrap-removing machine and landwaste feeder, be fixed with vibrosieve on the sledge seat, vibrosieve adopts the existing equipment mud vibrating screen.It is characterized in that: be fixed with an airtight metal shell on the sledge seat, vibrosieve is in airtight metal shell.Going out the debris port bottom and in housing, being fixed with the landwaste feeder and the spiral Scrap-removing machine at vibrosieve.Collect the landwaste that the screen cloth top of vibrosieve tumbles, and landwaste is transported to the outside of housing.Screen cloth bottom at vibrosieve is fixed with collecting tank, the drilling fluid that collecting tank collection screen Netcom is crossed.Have tapping line to connect collecting tank, the tapping line other end is connected with the discharge opeing slush pump.Top at housing is fixed with exhaust opening, and exhaust opening can be connected with exhaust plant.Top at housing is fixed with mud entrance, and mud entrance is on the top of vibrating screen mesh.
The discharge opeing slush pump is in hull outside and be fixed on the sledge seat; The motor of spiral Scrap-removing machine is in hull outside and be fixed on the sledge seat.
In order in time to discharge the drilling fluid in the collecting tank, in collecting tank, be fixed with Level meter, Level meter connects electric control box by holding wire, and electric control box connects the discharge opeing slush pump by lead.Liquid level in Level meter meets or exceeds the height of controlling organization regulation, and electric control box is opened the discharge opeing slush pump automatically, and the drilling fluid in the collecting tank is in time got rid of.
The beneficial effects of the utility model: the airtight vibrosieve of the utility model oil drilling, with metal shell that vibrosieve is airtight, avoid that isolated hydrogen sulfide gas evaporate into the work-yard in the vibrosieve course of work, harm personal security and contaminated environment;
Landwaste feeder and spiral Scrap-removing machine and collecting tank and Level meter are set in the housing, are convenient to timely chip removal, discharge opeing;
Chip removal motor and discharge opeing slush pump, Level meter are installed in outside the housing, avoid producing static, spark and cause under the high concentration hydrogen sulfide gas environment and fire;
Housing top is provided with exhaust opening, and exhaust opening can connect exhaust plant, discharges high concentration hydrogen sulfide gas in the housing.
Description of drawings
Fig. 1 is the utility model oil drilling with airtight Structure of Vibrating Screen generalized section.
Among the figure, 1. sledge seat, 2. discharge opeing slush pump, 3. collecting tank, 4. Level meter, 5. housing, 6. vibrosieve, 7. exhaust opening, 8. spiral Scrap-removing machine, 9. landwaste feeder, 10. mud entrance.
The specific embodiment
Embodiment 1: is example with the drilling well of socle oil with airtight vibrosieve, and the utility model is described in further detail.
Consult Fig. 1.The airtight vibrosieve of the utility model oil drilling mainly is made up of discharge opeing slush pump 2, collecting tank 3, Level meter 4, closed shell 5, vibrosieve 6, spiral Scrap-removing machine 8 and landwaste feeder 9.
On sledge seat 1, be fixed with a mud vibrating screen 6.Be fixed with an airtight metal shell 5 on sledge seat 1, vibrosieve 6 is in airtight metal shell 5.
Going out the debris port bottom and in housing 5, being fixed with a landwaste feeder 9 and a spiral Scrap-removing machine 8 at vibrosieve 6.The motor of spiral Scrap-removing machine 8 is outside and be fixed on the sledge seat 1 at housing 5.
Be fixed with a collecting tank 3 in the screen cloth bottom of vibrosieve 6.Have tapping line to connect collecting tank 3, the tapping line other end is connected with a discharge opeing slush pump 2.Discharge opeing slush pump 2 is outside and be fixed on the sledge seat 1 at housing 5.Be fixed with a Level meter 4 in collecting tank 3, Level meter 4 connects electric control box by holding wire, and electric control box connects discharge opeing slush pump 2 by lead.
