Below further improvement of the utility model:
Described sampling head comprises cyclone separator, described cyclone separator comprises separator body, the lower end of separator body has been threaded connection coarse particle gatherer, described separator body is provided with fixed mount and draft tube, the upper end of separation vessel is provided with threaded line pipe, threaded line pipe has been threaded columnar filter membrane squeeze, columnar filter membrane clip is provided with in described filter membrane squeeze, the lower end of filter membrane clip is provided with wire mattress, be provided with draft hood in filter membrane clip, filter membrane squeeze is threaded the gland that filter membrane clip and draft hood can be pressed in filter membrane squeeze.
Further improvement:
Described draft tube is rectangle, and bore is outer little interior large shape.
Further improvement:
Be provided with the first sealing gasket between coarse particle gatherer and separator body, between filter membrane squeeze and separator body, be provided with the second sealing gasket.
The utility model adopts technique scheme, and the structure of two air pump and two air chamber makes flow more stable, under can overcoming the impact of ore deposit downhole oil, water, mist; The design of filter membrane clip well can fix filter membrane, and can not damage filter membrane; The setting of woven wire can prevent filter membrane fold or break in employing process; Draft tube is rectangle, and bore is outer little interior large shape, can maintain the air velocity of air intake opening, can prevent the mud contamination filter membrane that sampled point splashes, and improves sampling precision; The setting of the first sealing gasket and the second sealing gasket can increase the sealing property of sampling head.
Be described further below in conjunction with accompanying drawing the technical solution of the utility model.
