Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] See also Figure 1-6 The utility model provides a technical solution: an oilfield chemical preparation device, including a base 1, a heating seat 2, a shell 3, a top cover 4, a stirring rod 5, a gear 6, a motor 7, a turntable 8, a connecting rod 9, a slider 10, a rack 11, a feeding pipe 12, a pipeline 13, an absorption box 14, a pipeline 2 15, a pipeline 3 16, an overflow pipe 17, and a one-way valve 18.

[0031] This device has the effect of full stirring, specifically:

[0032] A heating seat 2 is arranged on the upper surface of the base 1, and a shell 3 is arranged on the inner wall of the heating seat 2. The shell 3 is an open cylindrical structure, and a top cover 4 is arranged on the upper surface of the shell 3. The top cover 4 is a hollow structure. A card block is rotatably arranged on the outer surface of the shell 3, and a card slot is correspondingly arranged on the outer surface of the top cover 4. A stirring structure is arranged inside the shell 3, and the stirring structure is provided with two stirring rods 5 to stir the raw materials so that the stirring is more sufficient. The stirring structure includes a stirring rod 5, which is rotatably connected to the bottom surface of the shell 3, and a plurality of convex strips are arranged on the outer surface of the stirring rod 5. A gear 6 is arranged on the upper surface of the stirring rod 5, and the inner surface of the shell 3 is provided with a plurality of convex strips. The top cover 4 is provided with two groups of stirring rods 5 and gears 6. The surface of the top cover 4 is provided with a driving structure. The driving structure uses a slider 10 to realize the asynchronous movement of the two stirring rods 5. The driving structure includes a motor 7. The upper surface of the top cover 4 is fixedly installed with the motor 7. The output end of the motor 7 penetrates the upper surface of the top cover 4 and is connected with a turntable 8. The lower surface of the turntable 8 is rotatably connected with a connecting rod 9. The other end of the connecting rod 9 is rotatably connected with a slider 10. The slider 10 is slidably connected to the lower surface of the top cover 4, and the lower surface of the slider 10 penetrates the lower surface of the top cover 4. The lower surface of the slider 10 is connected with a rack 11, and the rack 11 is meshed with the gear 6.

[0033] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 6As shown, the block on the outer surface of the rotating shell 3 is separated from the slot on the surface of the top cover 4, the top cover 4 is removed from the top of the shell 3, the reactant is placed inside the shell 3, the top cover 4 is put back on the top of the shell 3, and the top cover 4 is fixed by the block and the slot. At this time, the rack 11 moves synchronously with the top cover 4 until it meshes with the gear 6, the heating seat 2 is started to heat the shell 3, so that the reactant in the shell 3 reacts, the motor 7 is started, the motor 7 drives the turntable 8 to rotate, the turntable 8 drives the connecting rod 9 to rotate, the rotating connecting rod 9 drives the slider 10 to slide back and forth on the surface of the top cover 4, the movement of the slider 10 drives the rack 11 to move, and the gear 6 is driven by the gear 6. The movement of the rack 11 drives the gear 6 to rotate, and the rotation of the gear 6 drives the stirring rod 5 to rotate. The rotating stirring rod 5 stirs the reactants in the outer shell 3. When the rack 11 is in reciprocating motion, when the rack 11 is engaged with one of the gears 6, it will drive one gear 6 to rotate. When the rack 11 moves to engage with the other gear 6, the other gear 6 stops rotating, so that the two stirring rods 5 inside the outer shell 3 are always in asynchronous rotation, and when the rack 11 moves in the reverse direction, it will drive the gear 6 to rotate in the reverse direction. The asynchronous and intermittently reversed double stirring rods 5 fully stir the reactants in the outer shell 3.

[0034] The device has the effect of facilitating the addition of reactants and absorbing waste gas, specifically:

[0035] A feeding pipe 12 is provided through the surface of the top cover 4. The feeding pipe 12 is a hollow tubular structure, and a rotatable and removable pipe cover is provided at the upper end of the feeding pipe 12. A pipe 13 is provided through the surface of the top cover 4. A waste gas absorption structure is provided on the upper surface of the base 1. The waste gas absorption structure collects and absorbs waste gas in the reaction process by using an absorption box 14 to prevent harm to the human body. The waste gas absorption structure includes an absorption box 14. The absorption box 14 is installed on the upper surface of the base 1. Waste gas absorption liquid is provided inside the absorption box 14. A pipe 2 15 is provided through the upper surface of the absorption box 14. The second pipe 15 has no contact with the absorption liquid. The upper surface of the absorption box 14 is penetrated by a third pipe 16. One end of the third pipe 16 is connected to the first pipe 13 through a hose. The other end of the third pipe 16 extends below the absorption liquid level inside the absorption box 14. An overflow pipe 17 is provided on the side surface of the absorption box 14. The overflow pipe 17 is C-shaped. Both ends of the overflow pipe 17 penetrate the side surface of the absorption box 14. The upper end of the overflow pipe 17 is lower than the second pipe 15. A one-way valve 18 is provided inside the lower end of the overflow pipe 17. The flow direction of the one-way valve 18 is from the overflow pipe 17 to the absorption box 14.

[0036] like Figure 1 , Figure 2 and Figure 5As shown, when the reactants in the shell 3 react, organic waste gas will be generated. The organic waste gas passes through the pipe 13 on the surface of the top cover 4, moves to the pipe 3 16 on the surface of the absorption box 14, and flows out from the other end of the pipe 3 16 to contact the waste gas absorption liquid in the absorption box 14. After the harmful part is absorbed by the absorption liquid, the gas is discharged from the pipe 2 15 on the surface of the absorption box 14. When too much gas enters the absorption box 14, the liquid level in the absorption box 14 rises. When the liquid level contacts the upper end of the overflow pipe 17, the liquid flows into the overflow pipe 17 and returns to the absorption box 14 through the one-way valve 18 at the lower end of the overflow pipe 17, thereby preventing too much gas from entering the absorption box 14 at the same time, causing the absorption liquid to overflow from the pipe 2 15.

[0037] Working principle: When the oilfield chemical preparation device is used, the motor 7 is started, and the motor 7 drives the turntable 8 to rotate. The rotating turntable 8 drives the slider 10 to reciprocate, thereby driving the rack 11 to reciprocate. The rack 11 drives the gear 6 to rotate, so as to realize the asynchronous rotation of the double stirring rods 5, and fully stir the reactants in the outer shell 3. A feeding pipe 12 is arranged through the surface of the top cover 4 to facilitate the timely addition of reactants to the inside of the device during the reaction. A waste gas absorption liquid is arranged in the absorption box 14, and the absorption box 14 is connected to the pipeline 13 at the top cover 4. The waste gas generated during the reaction enters the absorption box 14 and is absorbed, so as to avoid the waste gas escaping and being absorbed by the human body to cause harm, thereby increasing the overall practicality.
