Specific embodiment

The following describes the utility model in further detail with reference to the accompanying drawings, to enable those skilled in the art referring to explanation Book text can be implemented accordingly.

As shown in Figs. 1-5, the utility model provides a kind of fluid suction head for degassing equipment, including main body 110, is Cylindric, the inside of main body 110 coaxially opens up cylindrical cavity 111, and one end of the cavity 111 has mud inlet.Filter 120, it is disc-shaped, multiple filter hole 121 is opened up on filter 120；Filter 120 is fitted tightly over the outer of the mud inlet Side, and the diameter of filter 120 is slightly larger than the diameter of mud inlet, before so that the outer rim of filter 120 is resisted against main body 110 End.End cap 130 is hollow structure, and end cap 130 is coaxially set in the front end of main body 110, and internal screw thread is equipped in end cap 130, main Body 110 is equipped with external screw thread matched with the internal thread, and end cap 130 is threadedly attached in main body 110；End cap 130 Front end there is baffle 131, open up central through hole 132 on the baffle 131, the baffle 131 of end cap is by the outer rim of filter 120 It is pressed in main body 110.Filter hole 121 on filter is in communication with the outside by through-hole 132；During drawing mud, Filter 120 can directly contact mud, and mud can be entered in cavity 111 by filter 120 filter hole 121.

In another embodiment, the outer wall 133 of end cap 130 is hexa-prism, is carried out using spanner to end cap 130 with facilitating Disassembly.

In another embodiment, the central through hole 132 of end cap 130 is circle, to reduce blocking to filter hole 121, is made The area of the absorption mud of filter 120 is bigger, keeps the mud amount drawn in the unit time more.Preferably, the end cap 130 be stainless steel material, and intensity is bigger and is not easy to get rusty or be corroded.

It regard the bottom plate 112 of the end of main body 110 as connecting plate, the first connecting hole and second is opened up on bottom plate 112 and is connected Hole is connect, is respectively equipped with internal screw thread on first connecting hole and the second connecting hole.Mud tube 140, one end are equipped with external screw thread, and Through external screw thread along the first connecting hole that the axial direction of main body 110 is connected to the main body 110, make mud tube 140 and cavity 111 Connection；The other end of the mud tube 140 connects suction pumps.Flue 150, one end is equipped with external screw thread, and passes through external screw thread Axial direction along main body 110 is connected on the second connecting hole of the main body 110, is connected to flue 150 with the cavity 111； The other end of the flue 150 connects air pump.

Preferably, the filter 120 is stainless steel material, the thickness of filter 120 is at least 1mm；Filter 120 On filter hole 121 be evenly arranged, the distance between filter hole 121 be at least 1mm.By reasonably select filter material, Thickness and rationally setting filter hole spacing so that filter mechanical performance increase, mud by speed faster.

The workflow of the utility model are as follows: mud tube 140 is connect with suction pumps, extracts mud；Mud from mud ditch, Flow through end cap 130, filter 120, main body 110, mud tube 140, until degassing drum；In the process, to prevent filter 120 It is blocked by mud, the air pump being connected to flue 150 is opened in setting fixed time period (such as 30s), is blown from flue 150 Gas out carries out blowback to main body 110, the tamper adhered on filter 120 is broken up；Due to the impurity in mud, it is only It is attached on filter 120, so blowback process only needs 1s, impurity can be removed；Main body 110 is small in size, will not stockpile anti- The gas blown, so test data will not lose.Since air pump is arranged near mud ditch, the purge gas that air pump is drawn is mud The gas of stock tank nearby, can prevent gaseous contamination.

If necessary to dismantle maintenance, mud or when the components such as replacement filter, end cap and main body in cleaning main body, need by Sludge pipe 140 and flue 150 disassemble, and later disassemble end cap 130 from main body 110 by spanner, will filter Piece 120 is removed, later can the cavity 111 to main body clear up, or carry out part replacement；Disassembly process is simple, and need not By fluid suction head integral replacing, it is only necessary to replacement damage component.

Fluid suction head provided by the utility model for degassing equipment is equipped with flue, can be to imbibition by flue Head main body carries out blowback, and the tamper being attached on filter is blown off, and the fluid suction head for overcoming existing degassing equipment is easy to block up The defect of plug, to improve the working efficiency of degassing equipment.Flexible axle, stirring rod etc. are eliminated relative to existing fluid suction head device Component easy to damage, structure is simple, and accident rate is low.For end cap using being threadedly coupled, replacement is simple, is not susceptible to loss of data.Heavy When the more working environment of sand mud, compared with other fluid suction heads, spoilage is low, more adaptable.The body volume of fluid suction head Smaller, inner space is small, when blowback works, can ensure the real-time of mud test data；The purge gas that air pump is drawn is mud The gas of stock tank nearby prevents the gas for being carried out blowback using other gases or liquid and mud being caused to deviate from contaminated.Gas Blowback system can set timing system or manually opened.

It is not only in the description and the implementation although the embodiments of the present invention have been disclosed as above Listed utilization, it can be applied to various fields suitable for the present invention completely, for those skilled in the art, Other modifications may be easily implemented, therefore without departing from the general concept defined in the claims and the equivalent scope, this reality It is not limited to specific details and legend shown and described herein with novel.
