Drilling fluid powdered drug automatic adding device

Technical field

The utility model relates to the drilling fluid powdered drug automatic adding device that a kind of oil drilling is used.Be oil drilling auxiliary equipment, particularly, add powdered drug in drilling fluid time, the utility model can be used for automatically adding drilling fluid powdered drug, to regulate the performance of drilling fluid.

Background technology

In drilling operation course, need to, according to on-the-spot down-hole situation, regulate property of drilling fluid, regulate property of drilling fluid just need in drilling fluid, add drilling fluid medicine, and add time speed can not be too fast, affect in order to avoid cause the sharply variation of property of drilling fluid drilling well produce.Conventional drilling fluid medicine is except liquid on a small quantity, all the other are all pulverous, liquid drilling fluid medicine is difficult for dispersing while interpolation, so at situ of drilling well, measure few time, can use manpower that it is slowly added, measure large time and can add with suction pump, now can utilize by-pass valve control to open size and control addition and interpolation speed; And pulverous drilling fluid medicine, because situ of drilling well does not have automatic adding device, often need execute-in-place workman slowly to add with manpower control interpolation speed, again because pulverous drilling fluid medicine is easy to be blown to four winds, so in the time that situ of drilling well is manually added by operator, not only take more manpower, but also be easy to cause site operation personnel, in adding procedure, suck the aerial powdered drug of dispersing, that gives execute-in-place workman has healthyly caused certain harm.

Summary of the invention

The purpose of this utility model is a kind of drilling fluid powdered drug automatic adding device of design, makes it have and can, by automatically controlling, realize the interpolation speed of controlling powdered drug, to reach the object that regulates property of drilling fluid.The utility model is to pass through motor speed controller, carry out the speed of motor in control device, and then control the rotating speed of the utility model helical conveyor conveying axis, and regulate the rate of outflow of Powdered drilling fluid medicine, realize the automatic interpolation of Powdered drilling fluid medicine.

Use this technical solution to achieve the above object: drilling fluid powdered drug automatic adding device comprises filter screen, hopper, speed control cabinet, helical conveyor, stent-type hopper slide rail, suspending hook, height adjustment hole, channel guide cribbing, hopper cover plate, lifting suspension hook and buncher composition.In the middle of described hopper, be designed with filter screen, hopper is placed in stent-type hopper slide rail, stent-type hopper slide rail can be moved up and down by the constraint of channel guide cribbing, after aliging with the height adjustment hole on channel guide cribbing, the height adjustment hole on stent-type hopper slide rail can insert steady pin, to locate whole height of the present utility model; Described hopper fit beneath has helical conveyor, and the rotary power of helical conveyor is from buncher, and buncher is subject to the control of speed control cabinet; Four jiaos of described channel guide cribbings are designed with channel-section steel formula column, this column works to support the upper member such as hopper, also has the effect of the tie bracket formula hopper slide rail direction of motion, four chamfered groove steel formula column upper ends of channel guide cribbing, be designed with the utility model of can slinging and can fix again suspending hook of the present utility model, suspending hook bottom is designed with a groove, and during in order to lifting, lanyard cover uses, centre is designed with pin shaft hole, application when fixing.

The beneficial effects of the utility model are: because the utility model is metal body, therefore have enough intensity and reliability; Owing to being designed with filter screen in the utility model hopper, can prevent that the packaging bag of drilling fluid powdered drug from entering hopper bottom helical conveyor, stop up helical conveyor; Because the utility model whole height can regulate, use so be convenient to drilling team's resettlement in application process; Because the utility model is by variable speed electric motors, particularly control helical conveyor, therefore carrying drilling fluid powdered drug speed can conveniently control, and in the time that application the utility model carries out the interpolation of drilling fluid powdered drug, operator can install away from this, therefore can avoid sucking the aerial powdered drug of dispersing, can ensure the healthy of execute-in-place workman, there is significant social benefit.
