Description

Technical Field

[0001] The present application relates to the technical field of quartz sand processing equipment, and in particular to a quartz sand fracturing and shaping device. Background Art

[0002] After undergoing the fracturing and shaping process, quartz sand exhibits excellent compressive resistance and good roundness. Made from natural quartz sand through multiple meticulous processing steps, it is widely used in the oil industry, playing a particularly crucial role in hydraulic fracturing. During hydraulic fracturing, a high-pressure water pump injects fracturing fluid containing quartz sand into the oil and gas reservoir. The intense pressure fractures the reservoir, while the quartz sand embeds itself within the cracks, providing support and effectively preventing them from closing due to stress release. This maintains the reservoir's high conductivity, ensuring smooth oil and gas flow, and ultimately increasing oil and gas production.

[0003] Currently, the industry generally uses specialized fracturing and shaping equipment to fractur e quartz sand. This equipment typically utilizes a single shaping cylinder to uniformly crush and shape a batch of raw material (quartz sand). However, this processing method has significant drawbacks: if the batch processing volume is too large, the machine will be subjected to tremendous pressure, which may not only shorten the equipment lifespan but also affect the shaping quality of the batch of raw material. Conversely, if the batch processing volume is too small, the shaping efficiency will be low, making it difficult to meet the needs of large-scale production.

[0004] Furthermore, traditional processes employ a unified crushing and screening process, requiring repeated crushing and screening for substandard raw materials that do not meet the standard particle size. This repetitive operation not only makes it difficult to accurately control the mesh size ratio of the final product, but also results in low overall crushing efficiency due to the large number of ineffective crushing steps in the unified crushing process.

DETAILED DESCRIPTION

[0025] The following describes in detail embodiments of the present application, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limiting the present application.

[0026] The quartz sand fracturing and shaping device according to an embodiment of the present application will be described below with reference to the accompanying drawings.

[0027] like Figures 1-4 As shown, the quartz sand fracturing and shaping device according to an embodiment of the present application may include a frame 10, a pretreatment module, a diversion module 30 and a shaping module.

[0028] The frame 10 may include a first shell 101 , a second shell 102 and a third shell 103 that are sequentially connected from top to bottom, wherein a feed hopper 1011 and a discharge hopper 1012 are respectively provided on the upper and lower sides of the first shell 101 .

[0029] The pre-processing module may include two crushing rollers 201, wherein the two crushing rollers 201 are disposed inside the first housing 101 via a first drive member 202. The first drive member 202 is disposed outside the first housing 101 and may include a first motor 2021 and two drive wheels 2022, wherein the two drive wheels 2022 are meshed and respectively connected to the two crushing rollers 201, and the first motor 2021 is connected to one of the drive wheels 2022.

[0030] It should be noted that the first driving member 202 described in this embodiment has the ability to control the two crushing rollers 201 to rotate synchronously in opposite directions. By starting the first motor 2021, the first motor 2021 can drive the driving wheel 2022 connected to it to rotate, and the other driving wheel 2022 rotates accordingly, thereby prompting the two crushing rollers 201 to run synchronously, and can perform preliminary crushing on the passing raw materials.

[0031] The flow diversion module 30 may include a flow diversion core 301 and a plurality of guide plates 302. The flow diversion core 301 is disposed within the second housing 102, with an annular channel 33 formed therebetween. The annular channel 33 has a conical structure at the top and a cylindrical structure at the bottom. The guide plates 302 are circumferentially distributed within the annular channel 33 and are located between two adjacent inlets 401.

[0032] It should be noted that the upper part of the annular channel 33 described in this embodiment can divert the incoming raw materials. After the diversion, the raw materials can freely fall after passing through the cylindrical structure, thereby accelerating into the corresponding filter cartridge 42. During this process, the guide plate 302 described in this embodiment can ensure that the raw materials in the annular channel 33 enter the corresponding filter cartridge 42.

[0033] The shaping module may include multiple shaping cylinders 40 circumferentially distributed within the third housing 103. Each shaping cylinder 40 is rotatably provided with a filter cartridge 42. The filter cartridges 42 are each connected to a second drive member 43. The top and bottom of the shaping cylinder 40 are respectively provided with an inlet 401 and an outlet 402. The inlet 401 is connected to the annular channel 33. A crushing element 44 is connected to the shaping cylinder 40 and is located within the filter cartridge 42. The upper end of the crushing element 44 is connected to the top of the shaping cylinder 40, and the lower end of the crushing element 44 is provided with multiple striking arms 441. The multiple striking arms 441 are distributed in a spiral pattern.

[0034] The second driving member 43 may include a first turntable 431 and a plurality of second turntables 432 circumferentially distributed outside the first turntable 431, wherein a main gear 4312 is provided inside the first turntable 431 through a second motor 4311, the second turntables 432 correspond one-to-one to the shaping cylinder 40, and the second turntable 432 is arranged in the shaping cylinder 40. A slave gear 4321 is provided inside the second turntable 432, and the slave gear 4321 is connected to the shaft 421 at the bottom of the corresponding filter cylinder 42, and the slave gear 4321 is meshed with the main gear 4312.

[0035] It should be noted that the second driving member 43 described in this embodiment has the ability to control the synchronous rotation of multiple filter cartridges 42. By starting the second motor 4311, the second motor 4311 can drive the main gear 4312 to rotate, and the multiple slave gears 4321 will rotate synchronously, thereby prompting the multiple filter cartridges 42 to run synchronously, so that the raw materials can be processed synchronously in batches in multiple independent shaping cylinders 40. This batch processing mode helps to improve the shaping efficiency.

[0036] A dust removal mechanism 50 is provided on the frame 10, and the dust removal mechanism 50 may include a dust collector 501, a duct 502 and multiple branch pipes 503, wherein the dust collector 501 is arranged on the top of the first turntable 431, and the output end of the dust collector 501 is connected to the multiple branch pipes 503 through the duct 502, the branch pipes 503 correspond one-to-one to the shaping cylinder 40, and the input end of the branch pipe 503 is connected to the corresponding shaping cylinder 40.

[0037] It should be noted that the vacuum cleaner 501 described in this embodiment can generate a certain suction force on the multiple branch pipes 503 through the conduit 502, so that the dust generated in the shaping cylinder 40 respectively connected to each branch pipe 503 can be absorbed, thereby achieving a dust removal effect.

[0038] As a possible scenario, refer to Figure 1 Corresponding supporting components (such as legs, reinforcement rods, etc.) can be set on the frame 10 as needed to ensure smooth and stable operation of each part.

[0039] Specifically, when fracturing and shaping of raw materials is required, the relevant personnel first put the raw materials into the feed hopper 1011. After being crushed by the two crushing rollers 201, the raw materials enter the annular channel 33 through the discharge hopper 1012. Under the diversion effect of the diversion core, the raw materials can be evenly dispersed and fall on the outer surface of the diversion core. Under the action of multiple guide plates 302, the raw materials can enter the corresponding shaping barrels 40 for secondary shaping. During this process, the raw materials fall freely and enter the high-speed rotating filter barrel 42. This design enables the raw materials to produce strong impact and collision with the corresponding filter barrel 42 and the striking arm 441 while in the filter barrel 42, fully releasing the impact energy of the rock hitting the rock, and greatly improving the shaping efficiency of the raw materials.

[0040] After the raw materials are shaped to the required mesh size in the shaping cylinder 40, they can be discharged from the filter holes of the filter cylinder 42 in a timely manner. Multiple shaping cylinders 40 operate synchronously, so that each batch of raw materials can complete the shaping operation under the best working conditions. This batch processing mode improves the shaping efficiency.

[0041] The dust and the like generated inside the shaping cylinder 40 can be discharged into the corresponding branch pipes 503 respectively, and discharged through the conduit 502 and the dust collector 501, thereby achieving a dust removal effect.

[0042] In summary, the quartz sand fracturing and shaping device of the present embodiment divides the raw material into multiple independent shaping drums for simultaneous processing. The raw material enters the corresponding high-speed rotating crushing drum during free fall. This design generates strong impact and collision of the raw material during the shaping process, fully releasing the impact energy of the rock on rock, and significantly improving the shaping efficiency of the raw material.
