Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of lubricant reaction equipment, in particular to a liquid lubricant reaction kettle for drilling fluid. BACKGROUND

[0002] The liquid lubricant for drilling fluid is a high-performance lubricant synthesized by mineral oil, surfactant, extreme pressure lubricant, film-forming agent and other raw materials, which has good effect of reducing rolling friction and sliding friction, and can effectively reduce the torque and lifting resistance of drilling tools. The industry standard T / SHXH 06-2016 "Liquid Lubricant for Drilling Fluid" stipulates the classification and marking, technical requirements, test methods, inspection rules and other requirements of the liquid lubricant for drilling fluid.

[0003] In the production of the liquid lubricant for drilling fluid, the required amount of mineral oil, surfactant and other additives are added to the reaction kettle for stirring reaction. After sufficient reaction, the prepared liquid lubricant for drilling fluid is poured from the discharge port into the storage barrel to obtain the finished product of liquid lubricant. When the existing reaction kettle is used to stir the lubricant, the stirring position of the stirring rod is fixed, and it is found that the stirring area is constant, and it is not easy to mix the mineral oil and additives in different areas. A longer time is needed for stirring to fully mix the liquid in the entire tank, so as to meet the requirement of uniform mixing. SUMMARY

During the rotation of the first transverse stirring rod along the axis of the rotating shaft, the first transverse stirring rod moves up and down under the action of the lifting plate, thereby driving the second vertical stirring rod to move up and down, further driving the gear to rotate along the transmission rod and move back and forth along the transmission rod, the gear drives the poking block to move back and forth along the axial direction of the transmission rod through the cooperation of the guide groove and the clamping block, thereby driving the second vertical stirring rod to move back and forth along the axial direction of the transmission shaft, and further realizing the back-and-forth stirring of the materials in the center and the circumference of the tank during stirring, so that the stirring is more sufficient.

[0008] Further, the inner cavity of the sleeve is provided with a first cylindrical cavity and a second cylindrical cavity, the first cylindrical cavity is located above the second cylindrical cavity and the diameter of the first cylindrical cavity is larger than that of the second cylindrical cavity, a valve plate moving up and down is arranged in the first cylindrical cavity, the valve plate is sleeved on the rotating shaft, the upper end of the first cylindrical cavity is in communication with the space outside the sleeve, and the lower end of the second cylindrical cavity is in communication with the space outside the sleeve; the valve plate is located at the bottom of the first cylindrical cavity and closes the passage between the first cylindrical cavity and the second cylindrical cavity in a natural state, and the valve plate opens the passage between the first cylindrical cavity and the second cylindrical cavity under the extrusion of the liquid below when the sleeve is lowered, so that the liquid below enters the first cylindrical cavity.

[0009] Further, a long hole arranged vertically is formed in the side wall of the sleeve, a catch pin is fixedly connected to the outer wall of the rotating shaft, the catch pin passes through the long hole and is used for driving the sleeve to rotate synchronously with the rotating shaft.

[0014] Working Principle: During operation, a drive motor drives a rotating shaft to rotate, which in turn rotates the sleeve. The first and second horizontal stirring rods on the sleeve rotate to stir the materials above and below. A first vertical stirring rod, fixed to the first horizontal stirring rod, stirs the materials near the inner wall of the tank. Stirring is achieved through a stirring plate fixed to the first vertical stirring rod; the inclined stirring plate agitates the materials upwards, causing them to tumble and mix. The first horizontal stirring rod moves up and down under the action of a lifting plate, which in turn drives the stirring plate to move up and down, thus thoroughly mixing the materials. During the up-and-down movement of the first horizontal stirring rod, the second vertical stirring rod moves up and down, which in turn drives the gears along the transmission path. The rod rotates and moves back and forth along the transmission rod. The gear, through the guide groove and the locking block, drives the actuating block to move back and forth along the axial direction of the transmission rod, thereby driving the second vertical stirring rod to move back and forth along the axial direction of the transmission shaft. This achieves back and forth stirring of the material in the center and around the tank during the stirring process, making the stirring more thorough. At the same time as the first horizontal stirring rod moves up and down, the sleeve moves up and down together. When the sleeve moves upward, it drives the valve plate to move upward, thereby conveying the material in the sleeve upward. When the sleeve moves downward, the liquid below the sleeve enters the inner cavity of the sleeve. Through circulation, the lubricant below the sleeve in the tank is continuously pumped upward, thereby circulating and conveying the material at the bottom of the tank upward for mixing, accelerating the stirring and mixing evenly.

[0015] The present invention provides a liquid lubricant reactor for drilling fluid, which has the following advantages: while stirring the material, it can mix the liquids in different areas, thereby making the material mix more thoroughly, shortening the mixing time, and improving the mixing efficiency; and avoiding the problem of excessively long mixing time caused by the inability to stir some materials.
