Description

A mixing device for drilling fluid medicine

technical field

The utility model belongs to the technical field of drilling fluid treatment in the process of petroleum exploration and development, in particular to a mixing and dosing device for drilling fluid medicine in the process of petroleum exploration and development.

Background technique

In oil exploration and development operations, it is necessary to prepare drilling fluid to cool the working drill bit, and at the same time carry cuttings to the ground, so that drilling and workover operations can be carried out normally, and some chemicals, especially some highly viscous chemicals, need to be added to the drilling fluid , The drug mixing device is a necessary equipment for preparing drilling fluid and adding necessary chemical substances during the use of drilling fluid. The drilling fluid drug mixing device is installed on the drilling fluid tank. The traditional drug mixing device has disadvantages such as insufficient dissolution, low efficiency, and easy deposition of the mixed liquid due to the low manual speed and the fact that some of the added drugs are solid or flocculent.

The Chinese utility model patent No. ZL201120254851.0 discloses a drug tank device, which involves a drilling fluid dosing device. The drug tank device includes a stirrer, a drug tank, a slurry discharge assembly, and a mud tank. The drug tank is a hollow cylinder structure, the drug tank is equipped with a stirrer, the bottom of the drug tank is equipped with a slurry assembly, and the mud tank is located under the slurry assembly. The device is driven by a motor, the cost is relatively high, and there is a hidden danger of electric shock.

Utility model content

The technical problem to be solved by the utility model is to provide a medicine stirring device with simple structure, sufficient dissolution and high efficiency.

In order to achieve the above object, the technical scheme that the utility model takes is:

A mixing device for drilling fluid medicine, comprising a mixing barrel, a stirring mechanism is installed in the mixing barrel, a crank mechanism that drives the stirring mechanism to rotate is installed on the mixing barrel, and the crank mechanism includes a first bearing that is rotated and transferred to a The rotating shaft on the top wall of the mixing tank, the central axis of the rotating shaft is parallel to the central axis of the mixing tank. It includes a stirring rod that is rotated and transferred to the top wall of the mixing tank through the second bearing and is coaxial with the mixing tank. The upper end of the stirring rod is installed on the top wall of the mixing tank through the second bearing. For the second gear, the lower end of the stirring rod is fixed with a stirring impeller, the lower end of the stirring rod is fixed with a cutting blade, and the lower end of the side wall of the mixing barrel is provided with a pulping assembly.

The cutting blade is meniscus-shaped.

The distance between the position of the stirring impeller on the stirring rod and the bottom wall of the stirring barrel is 1/3 of the height of the stirring barrel.

The utility model uses a crank mechanism to drive the stirring mechanism to rotate for stirring, which can be manually operated, convenient to control the speed, and safe to use. A cutting blade is fixed at the lower end of the stirring, so that the medicine sinking into the bottom of the mixing barrel can be fully pulverized through the two blades. And stir evenly through the stirring impeller, so as to speed up the dissolution rate of the medicine and improve the dissolution efficiency of the medicine.

Description of drawings

Fig. 1 is a schematic structural view of an embodiment of the utility model.

detailed description

Below in conjunction with accompanying drawing, the utility model is further described.

As shown in Figure 1, a drilling fluid drug mixing device includes a mixing tank 1, the mixing tank 1 is a hollow cylinder structure, the lower end of the side wall of the mixing tank is provided with a slurry assembly 9, and a stirring mechanism is installed in the mixing tank 1 The mixing bucket 1 is equipped with a crank mechanism that drives the stirring mechanism to rotate. The crank mechanism includes a rotating shaft 11 mounted on the top wall of the mixing bucket through a first bearing 10. The central axis of the rotating shaft 11 is connected to the central axis of the mixing bucket 1. Parallel, the crank handle 2 is fixed on the upper end of the rotating shaft 11, and the first gear 3 coaxial with the rotating shaft is fixed on the lower end of the rotating shaft 11 after passing through the top wall of the mixing tank. And the stirring rod 6 coaxial with the mixing tank, the upper end of the stirring rod 6 is installed on the top wall of the mixing tank through the second bearing 4, the upper end of the stirring rod 6 is fixed with the second gear 5 meshing with the first gear 3, and the crank handle 2 The stirring rod 6 is driven to rotate by the first gear 3 and the second gear 5. The stirring impeller 7 is fixed on the lower end of the stirring rod 6. The stirring impeller 7 is composed of a plurality of blades, and the blades are uniformly distributed on the stirring rod 6 in a radial shape. The lower end of the mixing rod 6 is fixed with a cutting blade 8, the cutting blade 8 is crescent-shaped, and it is sharpened on the outer edge. When a large medicine block sinks into the bottom of the mixing bucket, the cutting blade 8 can fully pulverize the medicine and speed up the dissolution rate.

The distance between the position of the stirring impeller 7 on the stirring rod and the bottom wall of the mixing bucket is 1/3 of the height of the mixing bucket, so as to prevent the medicine from sinking at the bottom, so that the medicine is fully mixed and dissolved.

During the specific work of the utility model, shaking the handle 2 makes the first gear 3 and the second gear 5 engage and drive, and drives the stirring rod 6 to stir. The number of teeth on the first gear 3 and the number of teeth of the second gear 5 can be selected and set according to requirements. For example, when the number of teeth of the first gear 3 is greater than the number of teeth of the second gear 5, the stirring rod rotates faster and the medicinal solution is mixed more fully; When the number of teeth of the first gear 3 is less than the number of teeth of the second gear 5, turning the handle 2 saves effort.
