Description

Technical Field

[0001] This utility model relates to the field of quartz sand production technology, specifically a dewatering device for producing quartz sand for fracturing. Background Technology

[0002] Currently used oil fracturing proppants are generally classified into three categories: quartz sand, ceramsite proppants, and coated proppants. In recent years, with persistently low oil and gas prices, cost reduction and efficiency improvement have become the main themes of shale gas development. In North America, in addition to accelerating drilling and completion, the use of ceramsite has been greatly reduced, while the proportion of quartz sand in fracturing operations has been increased, or even eliminated altogether, significantly reducing the cost of fracturing materials and achieving profitable shale gas development under low oil and gas prices. During the production process, quartz sand needs to be cleaned to remove impurities from its surface, and then dried. Before the drying step, dehydration treatment is usually required.

[0003] A search revealed a Chinese patent document disclosing a dewatering device for fracturing quartz sand production [Application No.: CN202020534356.4]. This dewatering device for fracturing quartz sand production includes a housing and a solid-liquid separation filter. The solid-liquid separation filter is located inside the housing and connected to the inner wall of the housing. The surface of the solid-liquid separation filter is set at a certain angle to the longitudinal plane. The interior of the housing is divided by the solid-liquid separation filter to form a separation chamber and a liquid collection chamber.

[0004] The device disclosed in this patent can clean the surface of the filter plate by pressurizing gas. However, the positions of all the nozzles are fixed. Although there are many nozzles, the cleaning effect on the filter plate is not good in actual use. It is easy to create dead corners on the surface of the filter plate, which cannot achieve a thorough cleaning effect. The quartz sand that cannot be cleaned will affect the dewatering effect and reduce the applicability of the device. Utility Model Content

[0007] A filter plate is installed in the inner cavity of the box. A fixing rod is fixedly connected to the inner cavity of the box. Mounting brackets are rotatably connected to both sides of the surface of the fixing rod. A connecting rod is fixedly connected to one side of the mounting bracket. A cleaning mechanism is installed on the surface of the mounting bracket.

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0022] Please see Figure 1-4As shown, a dewatering device for producing fracturing quartz sand includes a housing 1. A feed hopper 2 is connected to the top of the housing 1. A filter screen 3 is installed inside the housing 1. The filter screen 3 has an arc-shaped structure. Quartz sand can be fed into the housing 1 through the feed hopper 2 and dewatered by the filter screen 3, thus separating water and quartz sand. A fixing rod 4 is fixedly connected to the inner cavity of the housing 1. Mounting frames 5 are rotatably connected to both sides of the fixing rod 4. A connecting rod 11 is fixedly connected to the side, which connects the two mounting brackets 5, making the mounting brackets 5 more stable when rotating. A cleaning mechanism 6 is installed on the surface of the mounting bracket 5. A fan 7 is bolted to one side of the housing 1. The air outlet of the fan 7 is connected to a telescopic hose 8. The other end of the telescopic hose 8 passes through the inner wall of the housing 1 and works in conjunction with the cleaning mechanism 6. Under this action, the fan 7 can accelerate the air, so that the air can be discharged into the cleaning machine through the telescopic hose 8. Inside the housing 6, the surface of the filter screen 3 is cleaned by the cleaning mechanism 6 to prevent excessive quartz sand from clogging the mesh of the filter screen 3 and affecting the dewatering effect. A power mechanism 9 is installed on one side of the housing 1. The power mechanism 9 works in conjunction with the connecting rod 11. Under this action, the cleaning mechanism 6 can swing through the cooperation of the power mechanism 9 and the connecting rod 11, thereby increasing the cleaning area of ​​the cleaning mechanism 6 and effectively improving the cleaning effect of the cleaning mechanism 6 on the filter screen 3. This further reduces the clogging of the filter screen 3 and effectively improves the applicability of the device. A drain valve 10 is installed at the bottom of the housing 1 to drain the water filtered inside the housing 1, thereby preventing the quartz sand from coming into contact with the water again. A guide plate 14 is fixedly connected to one side of the inner cavity of the housing 1. One side of the guide plate 14 has an inclined structure design. Under this action, the water can be guided by the shape of the guide plate 14, so that the water can be discharged from the drain valve 10, effectively reducing the water residue inside the housing 1.

[0023] The cleaning mechanism 6 includes two air distribution pipes 61 fixed to the surface of the mounting bracket 5. One side of each air distribution pipe 61 is connected to a nozzle 62, which is designed with an inclined structure. A connecting pipe 63 connects to the surface of each air distribution pipe 61, with the other end of the connecting pipe 63 connected to the other side of the air distribution pipe 61. One end of a telescopic hose 8 is connected to one side of the air distribution pipe 61. Under this action, air inside the telescopic hose 8 can flow into the two air distribution pipes 61 through the connecting pipe 63, and then be discharged through the nozzles 62, thereby cleaning the surface of the filter screen 3. The position and number of nozzles 62 further enhance the cleaning effect on the filter plate 3. Guide rods 13 are fixedly connected to both sides of the surface of the air distribution pipe 61, and guide grooves 12 are opened on both sides of the inner cavity of the box 1. The inner wall of the guide groove 12 is slidably connected to the surface of the guide rod 13. Under this action, the air distribution pipe 61 can be guided when it rotates through the cooperation of the guide groove 12 and the guide rod 13, so that the air distribution pipe 61 can be relatively stable when rotating, avoiding the air distribution pipe 61 being unstable when rotating and affecting the subsequent cleaning effect on the filter plate 3.

[0024] The power mechanism 9 includes a servo motor 91 bolted to one side of the housing 1. The output shaft of the servo motor 91 passes through the interior of the housing 1 and is rotatably connected to the inner wall of the penetration point. A rotating plate 92 is fixedly connected to the output shaft of the servo motor 91. A rotating seat 93 is rotatably connected to one side of the rotating plate 92. The surface of the rotating seat 93 is slidably connected to the surface of the connecting rod 11. Under this action, when the servo motor 91 drives the rotating plate 92 to rotate, the cleaning mechanism 6 can swing under the cooperation of the rotating seat 93 and the connecting rod 11, thereby improving the cleaning effect of the cleaning mechanism 6. Under the action of the material of the telescopic hose 8 itself, it will not affect the normal discharge of air, effectively improving the applicability of the device.

[0025] It is worth noting that the technical features such as the box 1, feed hopper 2, and filter plate 3 proposed in this technical solution should be regarded as the technology in the comparative case. The specific structure, working principle, and possible control methods and spatial arrangement of these technical features can be selected using conventional methods in this field. This technical solution will not elaborate further.

[0026] Working principle: First, when the surface of the filter plate 3 needs to be cleaned, the operator turns on the blower 7. Under the action of the blower 7, the air is accelerated and discharged into the air distribution pipe 61 through the telescopic hose 8. With the cooperation of the air distribution pipe 61 and the connecting pipe 63, the air is discharged through the nozzle 62, thereby cleaning the surface of the filter plate 3 and reducing the residue of quartz sand on the surface of the filter plate 3. Then, the servo motor 91 is turned on. Under the action of the servo motor 91, the rotating plate 92 drives the rotating seat 93 to slide on the surface of the connecting rod 11. With the cooperation of the rotating seat 93 and the connecting rod 11, the mounting bracket 5 drives the air distribution pipe 61 to swing, so that the nozzle 62 can also swing. This allows the nozzle 62 to clean the filter plate 3 from various angles, which not only improves the cleaning effect of the filter plate 3, but also improves the cleaning efficiency of the filter plate 3, effectively improving the applicability of the device. After cleaning, the air distribution pipe 61 and the servo motor 91 are turned off in sequence.
