[0025] Please see Figure 1-6This embodiment provides a technical solution: a heating device for continuous production of emulsifiers for oil-based drilling fluids, including a delivery pipe 1 and a continuous delivery mechanism 2;

[0026] Delivery pipe 1: A steam-heated jacket section 6 is provided in the middle of the pipe.

Then, the external liquid supply device is adjusted, and the unheated oil-based drilling fluid raw material enters the delivery pipe 1 through the inlet pipe 8. At this time, the external steam generator can be adjusted, and the steam enters the steam heating jacket section 6 and continues to circulate, raising the temperature in the steam heating jacket section 6 to the required heating temperature. At this time, the real-time temperature in the steam heating jacket section 6 can be judged by observing the pressure gauge 9. After being heated by the steam heating jacket section 6, the oil-based drilling slurry continues to be transported to the left until it is collected by the external liquid collection device on the outlet pipe 7, thus completing the function of continuous heating of oil-based drilling raw material.

[0027] Continuous conveying mechanism 2 includes a right sliding plate 21, a left sliding plate 22, a conveying cylinder 23, a spiral conveying plate 24, a limiting groove 25, and a sliding column 26. The left sliding plate 22 is rotatably connected to the left side of the inside of the conveying pipe 1, and the right sliding plate 21 is rotatably connected to the right side of the inside of the conveying pipe 1. The middle parts of both the right sliding plate 21 and the left sliding plate 22 are fixedly connected to the outer arc surface of a conveying cylinder 23. A spiral conveying plate 24 is fixedly connected to the middle of the outer arc surface of the conveying cylinder 23. Evenly distributed strip-shaped guide blocks are fixedly connected to the right side of the inner arc surface of the conveying cylinder 23. Limiting grooves 25 are respectively opened at the ends of the four strip-shaped guide blocks facing the central axis of the conveying pipe 1. Limiting sliders are slidably connected inside the four limiting grooves 25. The outer surface of each component is fixedly connected to the outer arc surface of a sliding column 26. A transmission rod is fixedly connected to the right end of the sliding column 26. A motor 4 is fixedly connected to the middle of the right side surface of the right limit plate 3. The output shaft of the motor 4 is fixedly connected to the right end of the transmission rod. The input end of the motor 4 is electrically connected to the output end of the control switch 5. The continuous conveying mechanism 2 also includes a conveying transmission assembly 27. The conveying transmission assembly 27 includes an elliptical guide groove 271, a spherical limit block 272, a sliding seat 273, a connecting rod 274, and a fixed seat 275. The fixed seats 275 are symmetrically fixedly connected to the right side surface of the right sliding plate 21. The two fixed seats 275 are rotatably connected to the inside of the two fixed seats 275 respectively. The right ends of the two connecting rods 274 are rotatably connected to the sliding seats 273 respectively. Spherical limiting blocks 272 are fixedly connected to the right end of 273. An elliptical guide groove 271 is opened on the left side of the right limiting plate 3. The outer surfaces of the two spherical limiting blocks 272 are slidably connected to the inside of an elliptical guide groove 271. The continuous conveying mechanism 2 also includes a left limiting post 28 and a left limiting sleeve 29. The left limiting post 28 is fixedly connected to the middle of the left side wall of the conveying pipe 1. The left limiting sleeve 29 is movably fitted on the outer arc surface of the left limiting post 28. The outer surface of the left limiting sleeve 29 is fixedly connected to the left side of the inside of the conveying cylinder 23. At this time, the control switch 5 can be adjusted, the motor 4 runs, the output shaft of the motor 4 rotates, thereby driving the transmission rod to rotate, thereby driving the sliding post 26 to rotate, thereby driving the conveying cylinder 23 to move. The rotation of the conveying cylinder 23 causes the right sliding plate 21 and the left sliding plate 22 to rotate within the conveying pipe 1. During the rotation of the conveying cylinder 23, the two spherical limiting blocks 272 slide continuously within the elliptical guide groove 271. Restricted by the elliptical direction of the elliptical guide groove 271, the two sliding seats 273 continuously move closer and further apart during rotation. This, in turn, via the connecting rod 274 and the fixed seat 275, propels the conveying cylinder 23 to reciprocate left and right movements. Simultaneously, the conveying cylinder 23 also reciprocates left and right movements during its own rotation. The oil-based drilling fluid raw material is a slurry containing small particles. After entering the conveying cylinder 23, it is first restricted by the spiral conveying plate 24, resulting in a spiral conveying effect that transports the oil-based drilling slurry to the left.When the oil-based drilling slurry moves to the steam-heated interlayer section 6, it is continuously heated. During the heating process, the rotating spiral conveyor blades 24 reciprocate, scraping off the oil-based drilling slurry on the side wall of the conveying pipe 1 to prevent it from sticking together due to high temperature.

[0028] The working principle of the continuous production heating device for emulsifiers for oil-based drilling fluid provided by this utility model is as follows: When the device is needed, it can be installed at the designated position through the flange on the outlet pipe 7 and the flange on the inlet pipe 8. Then, the external liquid supply device is adjusted, and the unheated oil-based drilling fluid raw material enters the delivery pipe 1 through the inlet pipe 8. At this time, the external steam generator can be adjusted, and steam enters the steam heating jacket section 6 and continuously circulates, raising the temperature in the steam heating jacket section 6 to the required heating temperature. At this time, the real-time temperature in the steam heating jacket section 6 can be judged by observing the pressure gauge 9. Then, the control switch 5 can be adjusted, the motor 4 can be turned, the output shaft of the motor 4 can be rotated, which in turn drives the transmission rod to rotate, which in turn drives the sliding column 26 to rotate, which in turn drives the delivery cylinder 23 to rotate, which in turn drives the right sliding plate 21 and the left sliding plate 22 to rotate in the delivery pipe 1. During the rotation of the delivery cylinder 23, it will drive the two spherical limit blocks. 272 slides continuously within the elliptical guide groove 271. Constrained by the elliptical direction of the guide groove 271, the two sliding seats 273 continuously move closer and further apart during rotation. This, in turn, drives the conveying cylinder 23 to reciprocate left and right movements via the connecting rod 274 and the fixed seat 275. Simultaneously, the conveying cylinder 23 also reciprocates left and right movements during its own rotation. The oil-based drilling fluid raw material is a slurry containing small particles. After entering the conveying cylinder 23, it is first subjected to the force of the spiral conveying plate 24. The spiral conveyor effect is limited, and the oil-based drilling slurry is conveyed to the left. When the oil-based drilling slurry moves to the steam-heated interlayer section 6, it will be continuously heated. During the heating process, the spiral conveyor plate 24 rotates and reciprocates, scraping off the oil-based drilling slurry on the side wall of the conveying pipe 1 to prevent it from sticking due to high temperature heating. After being heated by the steam-heated interlayer section 6, the oil-based drilling slurry continues to be conveyed to the left until it is collected by the liquid collection device outside the liquid outlet pipe 7, thus completing the function of continuous heating of oil-based drilling raw materials.

[0029] It is worth noting that the motor 4 and pressure gauge 9 disclosed in the above embodiments can be freely configured according to the actual application scenario. It is recommended that the motor 4 be an RV063-20-YS-0.75KW-NRMV three-phase asynchronous AC motor, and the pressure gauge 9 be a Y-150B model stainless steel pressure gauge. The control switch 5 is equipped with a control button corresponding to the motor 4 and used to control its switch.

[0030] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
