Description

Oil field sewage pipeline filter

The technical field is as follows:

the utility model belongs to the technical field of the oil field sewage treatment technique and specifically relates to an oil field sewage pipeline filter.

Background art:

in the oil field production, sewage pipeline filter is essential equipment, pipeline filter mainly is used for intercepting the particulate matter more than certain diameter in the sewage, be used for protecting sewage pump impeller unblock, the filter that generally uses at present is blue formula filter, install a blue formula filter screen through a tube-shape container, both ends are through flange joint on the pipeline, blue formula filter's filter screen is because entering sewage above the filter screen, the major diameter granule of interception all gathers in the filter screen, it has just need regularly to open the blind flange and clear up to pile up much, waste time and energy and need stop the pump, the untimely production accidents such as causing sewage pump evacuation easily of clearing up.

The utility model has the following contents:

in order to solve the problem, the utility model provides an oil field sewage pipeline filter.

The technical scheme of the utility model is that: an oil field sewage pipeline filter comprises a cylinder body, wherein a flange is welded on the upper part of the cylinder body, the two flanges are hermetically connected through bolts, an outlet pipe is welded on the flange on the upper part, the outlet pipe is connected with an outlet flange through a pipeline, the outlet flange is opposite to the cylinder body, and a pipeline is connected with an inlet flange on one side of the cylinder body;

a space ring is fixedly connected to the upper part of the inner hole of the cylinder body and above the inlet flange connecting pipe, a spring is arranged on the space ring, the upper part of the spring is in contact with the edge which is protruded in the circumferential direction of the filter screen, the filter screen is of an upper opening structure with a bottom, and the lower part of the filter screen is not in contact with the bottom of the cylinder body;

the bottom of the cylinder body is provided with a pipeline connected with a drain valve.

A section of conical pipe is arranged in a connecting pipe of a pipeline of the inlet flange, the conical pipe gradually shrinks from the water inlet direction, the diameter of the original pipeline is recovered through a plane after the conical pipe shrinks to the minimum diameter, and a pressure gauge is arranged on the pipeline of the inlet flange.

The outlet flange and the inlet flange are positioned on the same central line and are arranged perpendicular to the central line of the cylinder body.

The utility model discloses following beneficial effect has: set up the filter screen structure through spring coupling on the spacer ring, make the filter screen can fluctuate, when filtering rivers and producing undulant, under the condition of the vibration of floating from top to bottom of the filter screen, the major diameter granule attached to the filter screen outside drops from the filter screen surface and piles up in the barrel bottom, regularly discharge through the blowoff valve and pile up the major diameter impurity in the barrel bottom, need not to open the blind flange and clear up, also need not stop the pump influence normal production simultaneously in discharge impurity, set up the circular cone pipe on the inlet pipe, become the turbulent flow with the sewage in the former pipeline from the laminar flow, when the sewage that becomes turbulent flow flows through the filter screen, make the filter screen vibration from top to bottom that floats become fiercely, better will be attached to the major diameter granule of filter screen outside and drop from the vibration of filter screen surface, reduce the possibility that the filter screen blockked.

Description of the drawings:

fig. 1 is a schematic structural diagram of the present invention.

In the figure, 1-cylinder, 2-space ring, 3-spring, 4-flange, 5-inlet flange, 6-blowoff valve, 7-outlet flange, 8-filter screen, 9-conical pipe, 10-outlet pipe and 11-pressure gauge.

The specific implementation mode is as follows:

the present invention will be further explained with reference to the accompanying drawings:

as shown in fig. 1, the oil field sewage pipeline filter comprises a cylinder body 1, wherein a flange 4 is welded on the upper part of the cylinder body 1, the two flanges 4 are hermetically connected through bolts, an outlet pipe 10 is welded on the flange 4 on the upper part, the outlet pipe 10 is connected with an outlet flange 7 through a pipeline, the outlet flange 7 is opposite to the cylinder body 1, and a pipeline is connected with an inlet flange 5 on one side of the cylinder body 1;

the upper part of an inner hole of the barrel body 1 is fixedly connected with a space ring 2 at a position above a connecting pipe of an inlet flange 5, the space ring 2 is provided with a spring 3, the upper part of the spring 3 is contacted with a protruding edge of a filter screen 8 in the circumferential direction, the filter screen 8 is of an upper opening structure with a bottom, the lower part of the filter screen 8 is not contacted with the bottom of the barrel body 1, and the space ring 2 is provided with the filter screen 8 structure connected through the spring 3, so that the filter screen 8 can float up and down, and when the filtered water flow fluctuates, under the condition that the filter screen 8 floats up and down and vibrates, large-diameter particles attached to the outer part of the filter;

there is pipe connection blowoff valve 6 barrel 1 bottom, through blowoff valve 6 regular discharge pile up the major diameter impurity in barrel 1 bottom, need not to open the blind flange and clear up, also need not to stop the pump influence normal production when discharging impurity simultaneously.
