Description

Technical Field

[0001] The utility model relates to the technical field of drilling fluid lubricants, and particularly relates to a polymerization reaction device for drilling fluid lubricants. Background Technique

[0002] In the exploitation operation of complex oil and gas layers during oil and gas drilling, the drilling tools and instruments are in contact with the surface of underground rocks to work. Drilling fluid lubricants mainly include oil-based drilling fluid lubricants and water-based drilling fluid lubricants. The oil-based drilling fluid lubricants are composed of a base oil raw material and a variety of synergistic agents, and the synthesis of high-molecular compounds is realized through a polymerization reaction device;

[0003] The existing oil-based drilling fluid lubricants have disadvantages such as uneven aggregation and easy precipitation of oil phases, thus affecting the use effect.

[0004] The utility model patent with the publication number CN210974522U of a patent application discloses a polymerization reaction device for drilling fluid lubricants. In this structure, styrene monomer passes through a spray box one, a spray box two, a detection box, a drying box and a vacuum distillation box in sequence to obtain a suitable styrene monomer raw material. Then, the styrene monomer raw material is injected into the tank through the styrene monomer raw material interface, water source is injected through the water source interface, benzoyl peroxide is injected through the initiator interface, sodium dodecyl sulfate is injected through the emulsifier interface, and nitrogen is injected through the nitrogen interface. Under the protective nitrogen at room temperature, the servo motor is started. The servo motor drives the transmission shaft to rotate, so that the stirring rod stirs the solution inside the tank, and continuously stirs and emulsifies for 45 minutes. Then, the tank is heated by a heater to heat the emulsion system to 70 °C and continue to stir at this temperature for 8 hours to obtain polystyrene emulsion particles with a particle size of 10 - 70 nm. The structure of this device is clear and improves the practicability of the product.

[0005] However, when this structure is actually used, the servo motor drives the transmission shaft to rotate, and the stirring rod stirs the solution inside the tank. Since the stirring rod can only stir the solution in the middle layer of the tank during the working process, it is easy to cause the solution to be at the bottom of the tank, and the heater can only heat the bottom of the tank, resulting in insufficient heating of the solution inside the tank, thus affecting the use effect.

Then, through the conveying of the conveyor belt, the solution in the second motor is transported to the middle position inside the tank and then falls to the bottom, so as to carry out sufficient stirring, make the solution evenly heated, and achieve efficient mixing and uniform reaction of the solution.

Obviously, the described embodiments are part of the embodiments of the present utility model, rather than all of them. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0024] As shown in the attached Figures 1-5 The specific structure is set as follows: The drilling fluid lubricant polymerization reaction equipment includes a tank body 1.

A stirring mechanism is arranged inside the tank body 1;

[0025] The stirring mechanism includes a first motor 4 arranged inside the tank body 1. The output end of the first motor 4 is coaxially and drivably connected with a rotating shaft. Two first turntables 5 are sleeved on the rotating shaft. The surfaces of the two first turntables 5 are both meshed with a conveyor belt 6. A second turntable 7 is meshed inside the conveyor belt 6. A movable column is arranged inside the second turntable 7. The movable column is rotatably connected with the inner wall of the tank body 1. A plurality of conveying strips 8 are arranged on the surface of the conveyor belt 6. A conveying groove is opened inside each of the plurality of conveying strips 8. Start the first motor 4. The first motor 4 drives the rotating shaft to rotate. The rotating shaft drives the first turntable 5 to rotate. The first turntable 5 drives the conveyor belt 6 to move. The conveyor belt 6 drives the second turntable 7 to rotate. Thus, the conveying strips 8 on the surface of the conveyor belt 6 move, so as to scoop up the solution at the bottom of the tank body 1 into the second motor 9 opened on the surface of the conveying strip 8, and then convey the solution inside the second motor 9 to the middle position inside the tank body 1 through the conveying of the conveyor belt 6, and then fall to the bottom, so as to perform sufficient stirring, preventing uneven heating caused by too high temperature at the bottom and too low temperature at the top.

[0026] As shown in the attached Figures 2-3As shown in the figure, a second motor 9 is provided at the top of the tank body 1. The output end of the second motor 9 is coaxially drivingly connected to a rotating column 10. One end of the rotating column 10 penetrates through the tank body 1 and extends into the tank body 1. The bottom of the rotating column 10 is rotatably connected to a fixing strip 11. A plurality of first stirring rods 12 are provided on the surface of the rotating column 10. Second stirring rods 13 are provided at the bottoms of the plurality of first stirring rods 12. The shape of the second stirring rod 13 is set to be wavy. Start the second motor 9 to drive the rotating column 10 to rotate. The rotating column 10 rotates on the top of the fixing strip 11, thereby improving stability. At the same time, the rotating column 10 drives the first stirring rod 12 and the second stirring rod 13 to rotate. The first stirring rod 12 stirs the solution at the top inside the tank body 1, while the second stirring rod 13 stirs the solution in the middle of the tank body 1. Since the second stirring rod 13 is set to be wavy, it is to increase the contact area with the solution, so that the solution is stirred more fully and continuously stirred and emulsified.

[0027] As shown in the attached Figures 3-4 As shown in the figure, the heating mechanism includes a heat conduction sleeve 14 provided on the surface of the tank body 1.

The fixing ring 20, the support column 21 and the arc-shaped bottom plate 22 play a very good role in supporting and stabilizing, thus greatly improving the use effect. At the same time, the heat conduction layer 25 also plays a heat conduction effect, so that the temperature of the heater 15 can quickly enter the inside of the tank body 1.

[0029] The usage process of the present utility model is as follows: First, the processed styrene monomer raw material is injected into the interior of the tank body 1 through the feeding pipe 2, and benzoyl peroxide is injected through the feeding pipe 3. At the same time, external water source is injected into the interior of the tank body 1. After the feeding is completed, the second motor 9 is started to drive the rotating column 10 to rotate. The rotating column 10 rotates on the top of the fixing strip 11, thereby improving the stability. At the same time, the rotating column 10 drives the first stirring rod 12 and the second stirring rod 13 to rotate. The first stirring rod 12 stirs the solution at the top inside the tank body 1, while the second stirring rod 13 stirs the solution in the middle of the tank body 1. Since the second stirring rod 13 is arranged in a wavy shape, it is to increase the contact area with the solution, so that the solution is stirred more fully, and continuous stirring and emulsification are carried out;

[0030] At the same time, the first motor 4 is started. The first motor 4 drives the rotating shaft to rotate. The rotating shaft drives the first turntable 5 to rotate. The first turntable 5 drives the conveyor belt 6 to move. The conveyor belt 6 drives the second turntable 7 to rotate, so that the conveying strip 8 on the surface of the conveyor belt 6 moves. Thus, the solution at the bottom of the tank body 1 is scooped into the second motor 9 opened on the surface of the conveying strip 8, and then the solution inside the second motor 9 is conveyed to the middle position inside the tank body 1 through the conveying of the conveyor belt 6, and then falls to the bottom, so as to carry out sufficient stirring, preventing uneven heating caused by too high temperature at the bottom and too low temperature at the top;

[0031] Meanwhile, the tank body 1 is heated by the heater 15, and at the same time, the heat conduction layer 25 also plays a heat conduction effect, so that the temperature of the heater 15 can quickly enter the interior of the tank body 1, thereby maintaining a suitable temperature inside the tank body 1. At the same time, through the stirring of the stirring mechanism, the reaction is accelerated. Finally, it is discharged through the discharge pipe 23, which improves the working efficiency. At the same time, it is convenient to disassemble and repair the heater 15. First, rotate the fixing nut 19, so that the fixing nut 19 rotates on the threaded column 18 until it is separated from the threaded column 18, and then the heater 15 can be taken off. The heat preservation layer 24 is a heat preservation foam board, and the heat preservation layer 24 has a heat preservation effect on the tank body 1. The fixing ring 20, the support column 21 and the arc-shaped bottom plate 22 play a very good role in supporting and stabilizing, thus greatly improving the use effect.
