Description

Technical Field

[0001] This utility model relates to the technical field of quartz sand drying equipment, and in particular to a fracturing quartz sand drying system. Background Technology

[0002] In oil and gas extraction, hydraulic fracturing technology enhances oil and gas permeability by injecting high-pressure fluids (containing proppant) into the formation to create fractures. Quartz sand, a commonly used proppant, must possess high purity, high strength, and low moisture content (typically <1%) to ensure its effective distribution within the fractures and maintain conductivity. Drying is a core step in quartz sand processing; its efficiency and quality directly impact fracturing effectiveness and extraction economics. Therefore, a fracturing quartz sand drying system is needed.

[0003] Existing fracturing quartz sand drying systems often rely on internal baffles combined with external body rotation to move the quartz sand during the drying process. As the quartz sand rotates in one direction during the movement, it is prone to accumulation, resulting in poor drying efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a fracturing quartz sand drying system to solve the problem mentioned in the background art. In the existing fracturing quartz sand drying system, the movement of quartz sand is often achieved by internal baffles combined with the rotation of the outer body. During the movement, the quartz sand rotates in one direction, which easily leads to accumulation and poor drying efficiency.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a fracturing quartz sand drying system, comprising a first outer shell, a first gear ring fixedly fitted on the outer surface of the first outer shell, a first circular ring threadedly connected to one end of the first outer shell, a first connecting ring fixedly installed on one side surface of the first circular ring, a second gear ring fixedly installed on the outer surface of the first connecting ring, a second outer shell threadedly connected to one side surface of the first circular ring, a third gear ring fixedly fitted on the outer surface of the second outer shell, a fourth gear ring meshing on one side of the third gear ring, a first connecting post fixedly inserted through the center of the fourth gear ring, and a fifth gear ring fixedly fitted on one end of the first connecting post.

A fifth connecting post, which is fixedly connected to the sixth gear ring, is fixedly connected to one end of the seventh gear ring.

[0006] Preferably, a feed pipe is provided at one side opening of the second outer shell, and a hot air furnace is threadedly connected to one side of the feed pipe.

[0007] Preferably, the first connecting post is fixedly connected to the output end of the motor, and the motor is fixedly mounted on a mounting bracket on one side of the second housing.

[0008] Preferably, the outer ring of the first outer shell is threadedly connected to the discharge port, and a spiral plate is fixedly welded to the inner wall of the discharge port.

[0009] Preferably, the outer surfaces of both the first and second outer shells are fixedly welded with rollers, and rollers are attached to both sides of the rollers, with a second connecting post penetrating through the center of each roller.

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.

[0019] Please see Figure 1-4This utility model provides a technical solution: a fracturing quartz sand drying system, including a first outer shell 1, a first gear ring 3 fixedly fitted on the outer surface of the first outer shell 1, a first ring 4 threadedly connected to one end of the first outer shell 1, a first connecting ring 5 fixedly installed on one side surface of the first ring 4, a second gear ring 6 fixedly installed on the outer surface of the first connecting ring 5, a second outer shell 7 threadedly connected to one side surface of the first ring 4, a third gear ring 8 fixedly fitted on the outer surface of the second outer shell 7, a fourth gear ring 11 meshing on one side of the third gear ring 8, a first connecting post 12 fixedly inserted through the center of the fourth gear ring 11, a fifth gear ring 17 fixedly fitted on one end of the first connecting post 12, and the inner surface of the second outer shell 7... A first scraper 19 is attached to the first scraper 19. A connecting rod 20 is fixedly welded to one end of the first scraper 19. A second connecting ring 21 is fixedly welded to one end of the connecting rod 20. A third connecting post 22 is fixedly connected to the inner ring of the second connecting ring 21. A fourth connecting post 23 is fixedly welded to one side of the third connecting post 22. A support frame 24 is fixedly connected to one side of the fourth connecting post 23. A rotatable second ring 25 is fitted into the inner ring of the first ring 4. A second scraper 26 is welded to the inner ring surface of the second ring 25. A sixth gear ring 27 is meshed to one side of the third gear ring 8. A seventh gear ring 28 is meshed to one side of the second gear ring 6. A fifth connecting post 29, which is fixedly connected to the sixth gear ring 27, is fixedly connected to one end of the seventh gear ring 28.

[0020] Furthermore, a feed pipe 9 is provided at one side opening of the second outer shell 7, and a hot air furnace 10 is threadedly connected to one side of the feed pipe 9. Through the arrangement of the feed pipe 9 and the hot air furnace 10, a screw structure for conveying is provided inside the feed pipe 9, which can convey the quartz sand raw material into the second outer shell 7. The hot air furnace 10 can blow hot air in from the inlet on one side of the feed pipe 9 to facilitate drying.

[0021] Furthermore, the first connecting post 12 is fixedly connected to the output end of the motor 13, and the motor 13 is fixedly mounted on a mounting bracket on one side of the second housing 7. Through the setting of the motor 13, the motor 13 drives the fourth gear ring 11 and the fifth gear ring 17, and then the fourth gear ring 11 drives the third gear ring 8, the fifth gear ring 17 drives the first gear ring 3, and the third gear ring 8 drives the sixth gear ring 27. Since the sixth gear ring 27 and the seventh gear ring 28 are connected by the fifth connecting post 29, the sixth gear ring 27 can drive the seventh gear ring 28, and the seventh gear ring 28 then drives the second gear ring 6.

[0022] Furthermore, the outer ring of the first outer shell 1 is threadedly connected to the discharge port 14, and the inner wall of the discharge port 14 is fixedly welded with a spiral plate 15. Through the arrangement of the discharge port 14 and the spiral plate 15, the quartz sand is driven by the first outer shell 1 to accumulate on the inner wall of the discharge port 14. Since the spiral plate 15 is welded to the inner side of the discharge port 14 and the discharge port 14 is in a rotating state, the quartz sand can be smoothly carried out.

[0023] Furthermore, a rolling ring 2 is fixedly welded to the outer surface of both the first outer shell 1 and the second outer shell 7. Rollers 16 are attached to both sides of the rolling ring 2. A second connecting post 18 is connected through the center of the roller 16. With the arrangement of the rolling ring 2 and the roller 16, the surfaces of the rolling ring 2 and the roller 16 are smooth, which allows the second outer shell 7 and the first outer shell 1 to rotate smoothly during rotation. The roller 16 also provides a certain support during rotation.

[0024] Furthermore, the fourth gear ring 11 and the sixth gear ring 27 are respectively meshed and connected to both sides of the third gear ring 8. One end of the first connecting column 12 is supported by a support column connected by a bearing. With the arrangement of the third gear ring 8, the fourth gear ring 11 and the sixth gear ring 27, the fourth gear ring 11 drives the third gear ring 8, and the third gear ring 8 drives the sixth gear ring 27, thus enabling the roller to rotate smoothly.

[0025] Furthermore, both ends of the fourth connecting post 23 are fixedly installed with third connecting posts 22. The outer ring of the third connecting post 22 is equally spaced with second connecting rings 21. With the arrangement of the second connecting rings 21 and the third connecting post 22, the fourth connecting post 23 rotates and the second connecting rings 21 also rotate. Since the second connecting rings 21 are equally spaced in the inner ring of the third connecting post 22, they can rotate smoothly inside.

[0026] Working principle: First, quartz sand is fed into the feed pipe 9. The feed pipe 9 is equipped with a screw conveyor structure that transports the quartz sand raw material into the second outer shell 7. Hot air is blown into the second outer shell 7 from the inlet on one side of the feed pipe 9 by the hot air furnace 10. The motor 13 then drives the fourth gear ring 11 and the fifth gear ring 17. The fourth gear ring 11 drives the third gear ring 8, the fifth gear ring 17 drives the first gear ring 3, and the third gear ring 8 drives the sixth gear ring 27. Since the sixth gear ring 27 and the seventh gear ring 28 are connected by the fifth connecting column 29, the sixth gear ring 27 can drive the seventh gear ring 28. The seventh gear ring 28 then drives the second gear ring 6, causing the first outer shell 1 and the second outer shell 7 to rotate. The first outer shell 1 is threadedly connected to the first ring 4. Since the inner ring of the first ring 4 is fitted with a rotating second ring 25, the second ring 25 drives the support frame 24 to rotate. The support frame 24 is connected to the fourth connecting column 23. The fourth connecting column 23 drives the third connecting column 22. The third connecting column 22 drives the connecting rod 20 and the first scraper 19 to rotate. Since the first scraper 19 is inclined towards the discharge port 14, it can transport the quartz sand to the discharge port 14. The inner wall of the second ring 25 is provided with a second scraper 26, which facilitates the smooth passage of the quartz sand through the connection between the first outer shell 1 and the second outer shell 7, and finally transports it to the discharge port 14. Since the inner surface of the discharge port 14 is provided with a spiral plate 15, the quartz sand can be smoothly discharged through rotation.
