Abstract
Description
Technical Field
[0001] This utility model relates to the field of ceramsite proppant technology, specifically a ceramsite proppant preform drying device. Background Technology
[0002] Ceramsite proppant is an important material used in oil and gas extraction. It is mainly used to prop up fractures in oil and gas wells to keep the fractures open, thereby improving the efficiency of oil and gas extraction. It is usually made of ceramic materials and has the characteristics of high strength, high density, high wear resistance and good corrosion resistance. In the process of oil and gas extraction, ceramsite proppant is injected into the fractures of the oil and gas layer through fracturing operations. These proppant particles can maintain a stable shape and structure under high pressure, prevent the fractures from closing, and provide channels for the flow of oil and gas, thereby significantly improving the permeability and production of oil and gas.
[0003] Upon investigation, a Chinese utility model patent discloses a drying device for semi-finished ceramsite proppant (publication number: CN220818435U), which includes a base, a conveying body, a drying body, a fan, and a scraping mechanism.
[0004] Although the aforementioned patent optimizes the scraping mechanism through the above-mentioned structural arrangement, the semi-finished ceramsite proppant enters the drying body along with the conveyor body. Under the action of the servo motor, the rotating shaft rotates inside the support block. Under the action of the rotating shaft, the eccentric wheel block moves laterally inside the rectangular frame seat, causing the rectangular frame seat to move longitudinally inside the support. The rectangular frame seat drives the connecting rod to move the pressure rod through the push rod, causing the slide to move longitudinally back and forth. The slide seat drives the sleeve seat to move longitudinally, which in turn causes the slider and column at the bottom of the spring to move longitudinally back and forth. When the column comes into contact with the semi-finished ceramsite proppant, it scrapes it apart, thereby avoiding the problem of poor internal drying effect due to the accumulation of the semi-finished ceramsite proppant and improving the drying efficiency of the semi-finished ceramsite proppant to a certain extent.
[0005] However, during the process of scraping and spreading the accumulated ceramsite proppant semi-finished product, the process involves reciprocating longitudinal displacement of the ceramsite proppant semi-finished product. While the column is being moved, the ceramsite proppant semi-finished product is being continuously conveyed. This process prevents the ceramsite proppant semi-finished product from being scraped, resulting in an unsatisfactory scraping effect. This leads to uneven distribution of the material on the conveyor belt, severe local accumulation, and affects the uniformity of hot air penetration, thereby reducing overall drying efficiency and quality. Furthermore, because the ceramsite proppant semi-finished product has a certain degree of moisture and adhesion, it easily adheres to the surface of the conveying mechanism during transportation. This not only increases the resistance of equipment operation and energy consumption but also leads to material blockage and poor conveying, seriously affecting the continuity and stability of production.
[0006] Therefore, this utility model provides a drying device for ceramsite proppant blanks to solve the above problems. Utility Model Content

[0011] As a preferred technical solution of this application, one end of the straight pipe passes through one side of the adjacent drying rack and one side of the hot air plate in sequence.

[0012] As a preferred technical solution of this application, the inner cavity of the structural groove is provided with a fixing rod, the two ends of the fixing rod are respectively fixedly connected to the inner wall of the adjacent structural groove, and the outer ring of the fixing rod is provided with a limiting block, the top of the limiting block is fixedly connected to the bottom of the outer surface of the threaded sleeve.
[0013] As a preferred technical solution of this application, a protective shell is fixedly connected to one side of the top of the belt conveyor, and a first bevel gear is fixedly connected to one end of the connecting rod through one side of the adjacent protective shell.

[0017] (III) Beneficial Effects
[0018] By using a motor, lead screw, and screw sleeve, the fixed cone on the long plate displaces the semi-finished ceramsite proppant. The displacement direction of the long plate is opposite to the transmission direction of the belt conveyor. This reverse motion can more effectively and evenly disperse the semi-finished ceramsite proppant, avoiding accumulation during transportation. This uniform dispersion effect can improve the uniformity of hot air penetration, thereby improving the overall drying efficiency and quality.
[0019] By using a screw, connecting rod, first bevel gear, second bevel gear, short rod, first pulley, second pulley, and rotating rod, the cleaning arc plate can scrape off the residual ceramsite proppant semi-finished product on the belt conveyor.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.
[0028] This utility model provides a drying device for ceramsite proppant blanks, such as... Figures 1-5 As shown, the technical solution includes a belt conveyor 1, a drying rack 2 fixedly connected to the top of the belt conveyor 1, a hot air plate 20 fixedly installed in the inner cavity of the drying rack 2, a hot air blower 6 fixedly installed on one side of the drying rack 2, a straight pipe fixedly connected to one side of the hot air blower 6, a structural groove 7 opened on the inner wall of one side of the drying rack 2, a lead screw 16 provided in the inner cavity of the structural groove 7, a screw sleeve 17 sleeved on the outer ring of the lead screw 16, a long plate 14 fixedly connected to one side of the outer surface of the screw sleeve 17, a number of fixed cones 15 fixedly connected to the bottom of the long plate 14, a rotating rod 12 provided in the inner cavity of the belt conveyor 1, and a number of cleaning arc plates 13 fixedly connected to the outer ring of the rotating rod 12.
[0029] One end of the straight pipe passes through one side of the adjacent drying rack 2 and one side of the hot air plate 20. A motor 8 is fixedly installed on one side of the drying rack 2. One end of the lead screw 16 passes through the inner wall of the adjacent structural groove 7 through a bushing and is fixedly connected to a connecting rod 10. The other end of the lead screw 16 passes through the inner wall of the adjacent structural groove 7 through a bushing and is fixedly connected to the output shaft of the motor 8. After the motor 8 starts, its output shaft drives the lead screw 16 to rotate. The lead screw 16 transmits power to the subsequent structure through the connecting rod 10. At the same time, the hot air generated by the hot air blower 6 is transported to the inner cavity of the hot air plate 20 through the straight pipe and blown onto the ceramsite support material blank on the belt conveyor 1 through the holes on the hot air plate 20 to achieve the drying function.
[0030] The inner cavity of the structural groove 7 is provided with a fixing rod 19. The two ends of the fixing rod 19 are fixedly connected to the inner wall of the adjacent structural groove 7 respectively. The outer ring of the fixing rod 19 is fitted with a limiting block 18. The top of the limiting block 18 is fixedly connected to the bottom of the outer surface of the threaded sleeve 17. When the lead screw 16 rotates, the threaded sleeve 17 moves along the axial direction of the lead screw 16, and the limiting block 18 moves synchronously along the axial direction of the fixing rod 19. The fixing rod 19 plays a guiding role, while the limiting block 18 restricts the movement trajectory of the threaded sleeve 17, so that it can only move in a straight line, ensuring that the threaded sleeve 17 will not deviate or shake during the movement, thereby ensuring that the long plate 14 and the fixing cone 15 can stably disperse the ceramsite proppant material.
[0031] A protective shell 3 is fixedly connected to one side of the top of the belt conveyor 1. One end of the connecting rod 10 passes through the adjacent protective shell 3 and is fixedly connected to a first bevel gear 11. A short rod 21 is provided in the inner cavity of the protective shell 3. A second bevel gear 22 is sleeved on the outer ring of the short rod 21. When the motor 8 drives the lead screw 16 to rotate, the connecting rod 10 rotates accordingly and drives the first bevel gear 11 to rotate. The first bevel gear 11 meshes with the second bevel gear 22, thereby transmitting power to the short rod 21.
[0032] The first bevel gear 11 and the second bevel gear 22 are meshed by a snap-tooth engagement. One end of the short rod 21 is rotatably connected to the inner wall of the adjacent protective shell 3 through a rotating shaft. The other end of the short rod 21 extends through the inner wall of the adjacent protective shell 3 to one side of the protective shell 3. The outer ring of the extended end of the short rod 21 is fitted with a first pulley 5. The first bevel gear 11 and the second bevel gear 22 are meshed by snap-tooth engagement, transmitting power from the connecting rod 10 to the short rod 21. The short rod 21 rotates stably inside the protective shell 3 through the rotating shaft, transmitting power to the first pulley 5.
[0033] One end of the rotating rod 12 is rotatably connected to the inner wall of the adjacent belt conveyor 1 via a rotating shaft. The other end of the rotating rod 12 extends through the inner wall of the adjacent belt conveyor 1 to one side of the belt conveyor 1. The outer ring of the extended end of the rotating rod 12 is fitted with a second pulley 9. When the first pulley 5 rotates, it drives the second pulley 9 to rotate via the belt. The second pulley 9 then drives the rotating rod 12 to rotate. The rotation of the rotating rod 12 enables the cleaning arc plate 13 to scrape off the residual material on the belt conveyor 1.
[0034] The first pulley 5 and the second pulley 9 are connected by a belt winding. The bottom of the belt conveyor 1 is fixedly connected to a support frame 4, which provides stable support for the belt conveyor 1 and ensures that the belt conveyor 1 will not shake or tilt during operation.
[0035] Specifically: After the semi-finished ceramsite proppant requiring drying is placed on the belt conveyor 1, the operator starts the motor 8. The motor 8 drives the lead screw 16 connected to its output shaft to rotate. Under the threaded engagement between the lead screw 16 and the screw sleeve 17, the screw sleeve 17 is displaced along the axial direction of the lead screw 16. The limiting block 18 slides synchronously along the guide direction of the fixed rod 19, thereby ensuring the stability and accuracy of the linear displacement of the screw sleeve 17. The movement of the screw sleeve 17 further drives the long plate 14 to produce lateral displacement. The long plate 14 is connected to the fixed cone 15, which then disperses the semi-finished ceramsite proppant on the belt conveyor 1. Since the displacement direction of the long plate 14 is opposite to the transmission direction of the belt conveyor 1, the material can be more effectively dispersed during the dispersion process, avoiding local accumulation. The hot air generated by the hot air blower 6 is conveyed through a straight pipe. The hot air is blown into the inner cavity of the hot air plate 20 and evenly onto the ceramsite proppant semi-finished product through the holes distributed on the surface of the hot air plate 20, achieving an efficient and uniform heating and drying process. While the lead screw 16 rotates, the power is transmitted to the first bevel gear 11 through the connecting rod 10. The first bevel gear 11 drives the second bevel gear 22, which meshes with it, to rotate. The second bevel gear 22 is installed at one end of the short rod 21 and rotates with it. The short rod 21 drives the first pulley 5 to rotate, and drives the second pulley 9 to rotate synchronously through the belt drive connection. The second pulley 9 is coaxially connected to the rotating rod 12, thereby driving the rotating rod 12 to rotate. The rotation of the rotating rod 12 causes the cleaning arc plate 13 to scrape off the ceramsite proppant semi-finished product material remaining on the surface of the belt conveyor 1. The operator can set up a collection box below the rotating rod 12 to collect the scraped residue and prevent pollution and material waste.
[0036] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
