Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0027] Reference Figure 1-3 This utility model provides an embodiment of a high-efficiency sorting device for oil fracturing sand, comprising a shell 1, with multiple motors 3 fixedly connected to the left end of the shell 1, and raised rollers 4 fixedly connected to the drive ends of each motor 3. Multiple sliders 5 are slidably connected to the left side of the inner wall of the shell 1, and each slider 5 has a screen 7 on its inner wall. Connecting rods 8 are rotatably connected to both sides of the inner wall of the screen 7, and sliding cylinders 11 are slidably connected to the inner walls of the connecting rods 8. The outer walls of the sliding cylinders 11 are all located within the inner walls of the sliders 5. The device is connected to a knob 9, and a threaded rod 10 is fixedly connected to the rear end of each knob 9. The outer wall of the threaded rod 10 is threadedly connected to the inner wall of the slide cylinder 11. A locking rod 12 is slidably connected to both sides of the inner wall of the screen 7. A spring 13 is fixedly connected to one end of the locking rod 12 inward. The other end of the spring 13 is fixedly connected to the inner wall of the screen 7. Multiple slots 14 are provided on both sides of the inner wall of the outer casing 1. The outer wall of the locking rod 12 is set on the inner wall of the slot 14. The shape of the locking rod 12 fits the slot 14 for the installation and removal of the screen 7.
[0028] Specifically, during installation, first pull the levers 12 on both sides and align them with the slots 14. Then, using spring 2 13, the levers 12 are engaged in the slots 14. Next, rotate the knob 9 in the opposite direction to slide the slide cylinder 11 backward and insert it into the groove in the slider 5. This completes the installation. The screen 7 is made of stainless steel for use in high-temperature fracturing of oil. The left end of the observation window 2 is connected to the outer casing 1 via a latch. By rotating the knob 9 and pulling the levers 12, the screen 7 can be removed from the equipment. This allows for quick operation by a single person, significantly reducing downtime, lowering maintenance costs, ensuring the stability of the screen 7 to improve screening accuracy, and enabling rapid switching between multiple screen specifications to meet the needs of efficient and flexible oilfield production.
[0029] A processing cylinder 15 is fixedly connected to the top of the outer shell 1. A motor 17 is fixedly connected to the top of the processing cylinder 15. A solenoid valve 16 is fixedly connected to the lower side of the inner wall of the processing cylinder 15. An observation window 2 is rotatably connected to the front side of the inner wall of the outer shell 1. A transmission rod 18 is fixedly connected to the drive end of the motor 17. Multiple stirring rods 20 are rotatably connected to the inner wall of the transmission rod 18. Multiple heating plates 22 are fixedly connected to the inner wall of the processing cylinder 15. Gears 19 are fixedly connected to the outer wall of the stirring rods 20. Gear rings 21 are meshed with the outer wall of the gears 19. The top of the gear rings 21 is fixedly connected to the inner wall of the processing cylinder 15 for breaking up and drying the cracked sand. A spring 6 is fixedly connected to the bottom of the slider 5. The other end of the spring 6 is fixedly connected to the inner wall of the outer shell 1.
[0030] Specifically, a controller is installed at the front end of the outer casing 1. The controller is electrically connected to motor 1 3, solenoid valve 16, motor 2 17 and heating plate 22. Gear 19 and gear ring 21 are made of stainless steel. At the same time, a baffle is fixedly connected to the bottom of the transmission rod 18 to prevent cracked sand from entering gear 19 and gear ring 21 and affecting normal use. During processing, the exhaust fan on the right side of the inner wall of the processing cylinder 15 will also start simultaneously to exhaust the internal hot steam. By crushing, stirring and drying the cracked sand during screening, agglomeration, particle dispersion and moisture content can be eliminated, screen 7 can be prevented from clogging and screening deviation can be avoided, and the flowability and uniformity of materials can be improved. The overall efficiency is improved by integrating pretreatment and screening, and intermediate transfer losses are reduced.
[0031] Working principle: First, cracked sand is added into the processing cylinder 15 through the feed inlet at the front end. The controller starts motor 17 and heating plate 22, which heats the cracked sand. Motor 17 drives transmission rod 18 to rotate, which in turn drives multiple stirring rods 20 on the inner wall to rotate. Gear 19 rotates on the inner wall of gear ring 21, thus driving the stirring rods 20 to rotate and break up the cracked sand. After processing, the solenoid valve 16 is opened to discharge the processed cracked sand downwards. Motor 3 is then started, driving the raised roller 4 to rotate, which in turn drives the upper screen 7 to rotate. Simultaneously, the rotation causes the sliding cylinder 11 to move within the slider 5, moving the slider 5 towards... The screen moves upward and, through spring 6, drives slider 5 and screen 7 to rotate downward, thereby causing screen 7 to vibrate repeatedly and screen the screen. The sand that passes through the two screenings will be discharged downward, while the sand that does not pass through screen 7 will move to the right and be collected by the collection plate on the right. When it is necessary to disassemble screen 7, first turn the observation window 2 outward and turn the knobs 9 on both sides. The knobs 9 drive the threaded rod 10 to rotate and drive the slide cylinder 11 to slide forward. Take the slide cylinder 11 out of the inner wall of slider 5, release the limit on one side of screen 7, and pull the locking rods 12 on both sides inward to remove the locking rods 12 from the locking groove 14. This will release the limit on screen 7, allowing it to be removed and the disassembly completed.
[0032] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
