[0002] Quartz sand for fracturing is a key proppant used in hydraulic fracturing in oil and gas extraction. Its main function is to be injected into the formation under high pressure to support rock fractures and increase oil and gas production. The production process of quartz sand requires a series of steps such as washing, dehydration, and drying to clean the quartz sand.

[0003] Chinese utility model patent CN212262521 U discloses a dewatering device for fracturing quartz sand production, including "a box body; a solid-liquid separation filter screen, the solid-liquid separation filter screen being located inside the box body and connected to the inner wall of the box body, the surface of the solid-liquid separation filter screen being set at a certain angle to the longitudinal plane, and the interior of the box body being divided by the solid-liquid separation filter screen to form a separation chamber and a liquid collection chamber"; this device filters and drains quartz sand by setting multiple sets of filter screens and is equipped with a backwashing device to prevent the filter screen pores from clogging. However, the filtration method can only filter and drain excess water from the surface of the washed quartz sand, and the surface layer of the quartz sand body still contains a large amount of water. The dewatering effect of the quartz sand is not ideal, and its practicality is insufficient. Utility Model Content

[0004] The purpose of this invention is to provide a dewatering device for the production of fracturing quartz sand, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a dewatering device for producing quartz sand for fracturing, comprising a frame, a transmission assembly, a leveling roller, and a cleaning roller, wherein the transmission assembly, the leveling roller, and the cleaning roller are respectively arranged inside the frame;

[0006] The leveling roller is located above the conveying assembly, the cleaning roller is located on the bottom surface of the conveying assembly, and the outer wall of the cleaning roller is in close contact with the outer wall of the conveying assembly.

[0007] The inside of the frame is fixedly connected to a guide groove below the cleaning roller, the top surface of the front end of the frame is fixedly connected to a feed inlet, and the top surface of the rear end of the frame is fixedly connected to a drying rack.

[0008] A heating plate is installed on the upper surface inside the drying rack, a fan hood is fixedly installed on the top surface of the drying rack, and a centrifugal fan is fixedly installed on the top surface of the fan hood.

[0009] The transmission assembly includes a filter conveyor belt, the filter conveyor belt having multiple rotating rollers inside, one of which has a rotating wheel fixedly mounted at its end, and the side wall of the rotating wheel is connected to the output end of a drive motor fixedly mounted on the side wall of the frame.

[0010] The leveling roller includes a roller shaft, and multiple leveling plates are fixedly connected to the outer wall of the roller shaft in a circular arrangement around the axis. A rotating wheel is fixedly installed at one end of the roller shaft.

[0012] The beneficial effects of this utility model are as follows: This device, by setting up a transmission component, a heating plate, and a centrifugal fan, pours the cleaned quartz sand from the feed inlet onto the top surface of the transmission component. The quartz sand falling onto the top surface of the transmission component is transported by a filter conveyor belt, while excess water on the surface of the quartz sand is filtered and drained. The drained water falls into the guide groove on the bottom surface for collection and discharge. The filter conveyor belt carries the quartz sand through the drying rack. The heating plate heats the air blown out by the centrifugal fan, and the centrifugal fan continuously blows air, thereby drying and dehydrating the quartz sand, further improving the dehydration effect of the quartz sand.

[0014] The filter belt is further configured such that multiple filter holes are evenly distributed on its surface.

[0015] By adopting the above technical solution, the quartz sand on the top surface of the filter track is filtered and drained through the filter holes on the surface of the filter track during transportation, thereby performing the initial drainage and filtration of excess water on the surface of the quartz sand.

[0016] To achieve the effect of cleaning the surface of the filter track and the filter holes:

[0017] The cleaning roller is further configured to movably abut against the outer wall of the filter conveyor belt.

[0018] By adopting the above technical solution, the surface of the filter belt and the filter holes are cleaned by the continuous rotation of the cleaning roller, so as to avoid clogging of the filter holes and affect the dewatering effect.

[0019] To achieve the effect of synchronously driving the transmission wheel and the second rotating wheel to rotate:

[0020] The configuration is further defined as follows: the transmission wheel is connected to the first and second rotating wheels via chain drives.

[0021] By adopting the above technical solution, the rotating wheel one is driven by the drive motor, and at the same time, the transmission wheel and the rotating wheel two are driven to rotate synchronously through the transmission wheel and the chain.

[0022] The parts of the device not covered herein are the same as or can be implemented using existing technologies. Attached Figure Description

The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of the present invention in any way.

[0031] Please see Figures 1 to 6 A dewatering device for producing quartz sand for fracturing includes a frame 1, a transmission assembly 2, a leveling roller 3, and a cleaning roller 4. The transmission assembly 2, the leveling roller 3, and the cleaning roller 4 are respectively installed inside the frame 1.

[0032] The leveling roller 3 is located above the transmission assembly 2, and the cleaning roller 4 is located on the bottom surface of the transmission assembly 2, with the outer wall of the cleaning roller 4 in close contact with the outer wall of the transmission assembly 2.

[0033] Inside the frame 1, below the cleaning roller 4, a guide groove 5 is fixedly connected; a feed inlet 6 is fixedly connected to the top surface of the front end of the frame 1; and a drying rack 7 is fixedly connected to the top surface of the rear end of the frame 1.

[0034] A heating plate 8 is installed on the upper surface inside the drying rack 7, and a fan hood 9 is fixedly installed on the top surface of the drying rack 7. A centrifugal fan 10 is fixedly installed on the top surface of the fan hood 9.

[0035] The transmission assembly 2 includes a filter track 21, and the filter track 21 is provided with multiple rotating rollers 22 inside. One of the rotating rollers 22 has a rotating wheel 23 fixedly installed at its end. The side wall of the rotating wheel 23 is connected to the output end of the drive motor 24 fixedly installed on the side wall of the frame 1.

[0036] The leveling roller 3 includes a roller shaft 31. Multiple leveling plates 32 are fixedly connected to the outer wall of the roller shaft 31 in a circular arrangement around the axis. A rotating wheel 33 is fixedly installed at one end of the roller shaft 31.

[0037] A drive wheel 41 is fixedly installed at the end of the cleaning roller 4.

[0038] In this embodiment, as Figure 4 As shown, multiple filter holes are evenly distributed on the surface of the filter track 21.

[0039] In this embodiment, as Figure 2 , Figure 3 and Figure 4 As shown, the outer wall of the cleaning roller 4 is in contact with the outer wall of the filter conveyor belt 21.

[0040] In this embodiment, as Figure 1 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, the transmission wheel 41 is connected to the first rotating wheel 23 and the second rotating wheel 33 by a chain 11.

[0041] The computer software involved in the hardware carriers such as the drive motor and centrifugal fan in the technical solution is software technology known to those skilled in the art. It is merely applied to the aforementioned hardware carriers. In other words, the computer software portion of the technical solution is an essential technical feature for solving the aforementioned technical problem, constituting a necessary technical feature for the technical problem solved by this application, but it is not a differentiating technical feature or a point of technical improvement. The applicant has not made any technical improvements to the computer software portion involved in the aforementioned hardware carriers, nor is it a key technical point of the invention.

[0042] Therefore, the "drive motor", "centrifugal fan", etc. involved in this application are physical functional modules that combine computer software programs or protocols in the prior art with the hardware carrier of this application. The computer software programs involved in these physical functional modules are all technologies known to those skilled in the art and are not improvements of this application. The improvement of this application should be the interaction relationship between the various physical functional modules, that is, the improvement of the overall structure of the automatic dipping machine of this application, so as to solve the corresponding technical problems to be solved by this application.

[0043] The dewatering equipment for fracturing quartz sand production operates as follows:

[0044] First, the cleaned quartz sand is poured into the frame 1 through the feed port 6 and evenly spread on the top surface of the filter belt 21. After the drive motor 24 starts, it drives the first rotating wheel 23 to rotate. It is connected by the chain 11 and synchronously drives the transmission wheel 41 and the second rotating wheel 33 to rotate. In turn, it drives the rotating roller 22 and the cleaning roller 4 to work together. The filter belt 21 transports the quartz sand smoothly under the drive of the rotating roller 22. During the transportation process, the moisture on the surface of the quartz sand seeps into the guide groove 5 through the filter holes of the filter belt 21 and is discharged.

[0045] When the quartz sand is transported to the bottom of the drying rack 7, the centrifugal fan 10 starts, and the airflow is guided by the air hood 9 and heated by the heating plate 8, forming hot air that is continuously blown onto the quartz sand on the filter conveyor belt 21 to achieve efficient drying. The roller shaft 31 of the leveling roller 3 drives the leveling plate 32 to rotate continuously, so that the quartz sand entering from the feed port 6 is evenly spread and avoids accumulation that affects the drying effect. The cleaning roller 4 keeps the filter conveyor belt 21 clean and ensures that the filter holes are unobstructed.

[0046] The drive motor 24 can be the known model 1PM4105-2LF86-1 CS1, and the centrifugal fan 10 can be the known model SS4-1. Both are known existing technologies and can be used, but are not limited to these models.
