Technical Field

[0001] This invention relates to the technical field of equipment for the production of quartz sand proppant, specifically to a production and preparation device for high-strength quartz sand proppant. Background Technology

[0002] With the continuous deepening of oil and gas field exploration and development, especially the development of unconventional oil and gas resources such as shale oil and tight oil, higher requirements have been placed on the fracturing and production enhancement technology of oil and gas wells. Quartz sand is a commonly used fracturing proppant. In the process of preparing quartz sand proppant, the particle size of the raw quartz sand is related to the subsequent use effect of the quartz sand proppant and also determines the purity of the quartz sand proppant. Therefore, the particle size control of the raw quartz sand is crucial before preparation. Since the raw quartz sand has different shapes and sizes and may also contain nodules, in order to ensure the quality of the quartz sand proppant, the raw quartz sand needs to be ground and screened before production. For this purpose, a production and preparation device for high-strength quartz sand proppant is proposed. Summary of the Invention

The rod is rotatably connected on the side away from the limiting bracket inside. The two turntables are fixedly connected on their corresponding sides by a pin. A rotating shaft is rotatably connected inside the second support frame. The first support frame is set at the bottom of the second support frame.

[0007] Furthermore, the outer surface of the support chamber is fixedly connected to the inner ring of the water storage tank. Several nozzles are installed at the top of the cleaning cylinder, and the inlet ends of these nozzles are fixedly connected to the outlet end of the submersible pump inside the water storage tank. A support frame is fixedly connected to the top of the inner wall of the cleaning cylinder. A hollow rotating shaft is rotatably connected inside the support frame, passing through the support frame and extending to the top and bottom.

Drain pipes are fixedly connected to the left and right sides of the bottom of the support chamber. Both drain pipes penetrate the support chamber and extend into the washing cylinder. Filter screens are fixedly connected inside both drain pipes. By having several washing rollers 1 and several washing rollers 2 rotate in opposite directions, the stirring and friction effect is greatly improved, and the washing effect is also greatly improved, reducing the residue of impurities in the quartz sand.

[0009] The present invention has the following beneficial effects: (1) The present invention sets up a screening component. Specifically, the motor is started and the grinding disc is driven by the action of gear one to grind and screen the quartz sand. When the rotating shaft one rotates, it will drive the rotating rod one to rotate through the action of bevel gear one and bevel gear two. When the rotating rod one rotates, it will drive the filter plate to move up and down through the action of the turntable and the support rod. At the same time, when the filter plate moves, it will apply a certain force to the spring. At the same time, the spring will generate a certain rebound force and drive the filter plate to reset. In this way, the vibration effect of the filter plate is achieved and the quartz sand is screened. Impurities and inclusions on the surface of the quartz sand can be further removed. It can separate coarse particles with more impurities or fine particles that do not meet the purity requirements, thereby improving the purity of the high-strength quartz sand proppant.

[0010] (2) The present invention sets up a circulation component, specifically starting the second motor to drive the second rotating shaft to rotate. When the second rotating shaft rotates, it will drive the auger to rotate. When the auger rotates, it will discharge the quartz sand that does not meet the standard from the discharge pipe. The discharged quartz sand will re-enter the support chamber for grinding and screening until it meets the standard. This avoids manual intervention, greatly reduces the workload of the staff, and greatly improves the product quality and production efficiency.

[0011] (3) The present invention sets up a cleaning component, specifically, when the rotating rod 2 rotates, it drives the bevel gear 4 to rotate through the bevel gear 3. When the bevel gear 4 rotates, it drives several cleaning rollers 2 to rotate through the action of the rotating shaft 3 and the connecting bracket 2. When the several cleaning rollers 2 move, they will stir and rub the quartz sand. At the same time, when the bevel gear 3 rotates, it will also drive the bevel gear 5 to rotate. When the bevel gear 5 rotates, it will rotate through the hollow rotating shaft and the connecting bracket 1. When the connecting bracket 1 rotates, it will drive several cleaning rollers 1 to rotate and stir and rub the quartz sand raw material. Moreover, the several cleaning rollers 1 and several cleaning rollers 2 rotate in opposite directions, which greatly improves the stirring and friction effect and the cleaning effect, reduces the residue of impurities in the quartz sand, and is conducive to the uniform mixing of various additives and quartz sand in the subsequent production process, thereby improving the performance of the final product.

[0018] The feed pipe 314 is fixedly connected to the bottom right side of the conveying cylinder 311 on the side away from the support chamber 111. A second motor 312 is fixedly connected to the top of the conveying cylinder 311. A first discharge pipe 315 is fixedly connected to the top right side of the conveying cylinder 311. The side of the first discharge pipe 315 away from the conveying cylinder 311 is fixedly connected to the top of the support chamber 111. A second rotating shaft 316 is rotatably connected inside the conveying cylinder 311. The bottom output end of the conveying cylinder 311 is fixedly connected to the top of the second rotating shaft 316 via a coupling. An auger 317 is installed inside the conveying cylinder 311, and the interior of the auger 317 is fixedly connected to the outer surface of the second rotating shaft 316. A support plate 313 is fixedly connected to the bottom. The right side of the support plate 313 is fixedly connected to the left side of the support chamber 111. A cleaning cylinder 414 is set at the bottom of the grinding disc 216. The starting motor 312 drives the rotating shaft 316 to rotate.

[0019] The outer surface of the support chamber 111 is fixedly connected to the inner ring of the water storage tank 411. Several nozzles 418 are installed on the top of the cleaning cylinder 414.

When the bevel gear 420 rotates, it drives several cleaning rollers 2 427 to rotate via the action of the rotating shaft 3 421 and the connecting bracket 2 426. When the several cleaning rollers 2 427 move, they stir and rub the quartz sand. At the same time, when the bevel gear 3 415 rotates, it also drives the bevel gear 5 422 to rotate. When the bevel gear 5 422 rotates, it drives the hollow rotating shaft 423 and the connecting bracket 1 424 to rotate. When the connecting bracket 1 424 rotates, it drives several cleaning rollers 1 425 to rotate and stir and rub the quartz sand raw material. The several cleaning rollers 1 425 and several cleaning rollers 2 427 rotate in opposite directions, which greatly improves the stirring and friction effect and the cleaning effect. It also reduces the residue of impurities in the quartz sand and is conducive to the uniform mixing of various additives and quartz sand in subsequent production processes, thereby improving the performance of the final product.

[0020] A limiting frame 416 is rotatably connected to the outer surface of the rotating rod 419. The front and back of the limiting frame 416 are fixedly connected to the inner wall of the support frame 417. A connecting bracket 424 is provided at the bottom of the support frame 417. The interior of the connecting bracket 424 is fixedly connected to the outer surface of the hollow rotating shaft 423. Several cleaning rollers 425 are rotatably connected to the side of the connecting bracket 424 away from the support frame 417. A connecting bracket 426 is provided at the bottom of the several cleaning rollers 425. The interior of the connecting bracket 426 is fixedly connected to the outer surface of the rotating shaft 421. Next, a number of cleaning rollers 427 are rotatably connected to the side of the rotating shaft 421 near the side of the cleaning rollers 425. Scrapers 428 are fixedly connected to the left and right sides of the connecting bracket 426. The sides of the two scrapers 428 away from the connecting bracket 426 are in contact with the inner wall of the cleaning cylinder 414. Drain pipes 412 are fixedly connected to the left and right sides of the bottom of the support chamber 111. Both drain pipes 412 penetrate the support chamber 111 and extend into the inside of the cleaning cylinder 414. Filter screens are fixedly connected inside both drain pipes 412.

[0021] In use, firstly, the quartz sand raw material is added into the support chamber 111 through the feed inlet 112. Then, the motor 211 is started to drive the rotating shaft 217 to rotate. When the rotating shaft 217 rotates, it drives the grinding disc 215 to rotate through the action of the gear 214. When the grinding disc 215 rotates, it grinds the quartz sand in conjunction with the grinding disc 216, crushing larger or nodular lumps in the quartz sand. The crushed quartz sand falls down from the grinding disc 216 and lands on the top of the filter plate 226. At the same time, when the rotating shaft 217 rotates, it drives the bevel gear 218 to rotate. When the bevel gear 218 rotates, it drives the rotating rod 221 to rotate through the bevel gear 219. The rotating rod 221 rotates... When the filter plate vibrates, it drives the turntable 220 to rotate. Simultaneously, the rotation of the turntable 220, through the support rod 222, causes the limiting bracket 223 to move up and down. When the limiting bracket 223 moves up and down, it drives the filter plate 226 to move as well. At the same time, the movement of the filter plate 226 applies a certain force to the spring 224. The spring 224, limited by the fixing block 225, stores its force and generates a certain rebound force, causing the filter plate 226 to reset. This achieves the vibration effect of the filter plate 226. When the filter plate 226 vibrates, it screens the quartz sand that meets the standards, while preventing the quartz sand from clogging the filter plate 226. The quartz sand that meets the standards continues to fall downwards, while the quartz sand that does not meet the standards exits through the feed pipe. 314 is used for discharge. Grinding and sieving the quartz sand further removes impurities and inclusions from its surface, separating coarse particles with high impurities or fine particles that do not meet purity requirements, thereby improving the purity of the high-strength quartz sand proppant. Quartz sand that does not meet the standards enters the conveying cylinder 311 through the feed pipe 314. At this time, motor 312 is started, driving shaft 316 to rotate. Simultaneously, shaft 316 drives auger 317 to rotate, discharging the substandard quartz sand through the discharge pipe 315. The discharged quartz sand then re-enters the support chamber 111 for grinding and sieving until it meets the standards, avoiding manual intervention and significantly reducing labor costs. This significantly reduces the workload of the workers, improves product quality, and increases production efficiency. Standard-compliant quartz sand falls into the cleaning cylinder 414. At this time, the submersible water pump inside the water tank 411 sprays the cleaning solution through several nozzles 418. The sprayed cleaning solution falls into the cleaning cylinder 414 and mixes with the quartz sand. Simultaneously, when the turntable 220 rotates, it drives the rotating rod 419 to rotate. The rotation of the rotating rod 419, in turn, drives the bevel gear 420 to rotate via the bevel gear 415. The rotation of the bevel gear 420 drives the rotating shaft 421 to rotate. The rotating shaft 421 rotates within the hollow rotating shaft 423, and simultaneously, the rotation of the rotating shaft 421 drives the connecting bracket 426 to rotate.As the connecting bracket 2 426 rotates, it drives several washing rollers 2 427 to rotate as well. The movement of these washing rollers 427 agitates and rubs the quartz sand. Simultaneously, the rotation of bevel gear 3 415 drives bevel gear 5 422 to rotate. The rotation of bevel gear 5 422, in turn, drives the connecting bracket 1 424 to rotate via the hollow shaft 423. The hollow shaft 423 rotates within the support frame 417, which, through its fixed connection to the inner wall of the washing cylinder 414, provides support for the discharge pipe 2 413. The rotation of the connecting bracket 1 424 drives several washing rollers 1 425 to rotate, which in turn agitates and rubs the quartz sand raw material. Furthermore, several cleaning rollers 425 and 427 rotate in opposite directions, significantly enhancing the stirring and friction effect, thereby greatly improving the cleaning effect, reducing the residue of impurities in the quartz sand, and facilitating the uniform mixing of additives with the quartz sand in subsequent production processes, thus improving the performance of the final product. The wastewater after cleaning is discharged through drain pipe 412, which contains a filter screen. The cleaned quartz sand is then discharged through discharge pipe 413. Valves are installed on the outside of both drain pipe 412 and discharge pipe 413. Simultaneously, when connecting bracket 426 rotates, it drives two scrapers 428 to rotate, scraping the inner wall of the cleaning cylinder 414 to prevent quartz sand residue.
