Description

Technical Field

[0001] The utility model relates to the technical field of petroleum fracturing sand screening, in particular to a raw sand screening device for petroleum fracturing sand. Background Art

[0002] Petroleum fracturing sand is a kind of high-purity quartz sand, which is finely processed and has strong compression resistance and roundness. This kind of fracturing sand is often used in the field of petroleum industry as a petroleum proppant and is an indispensable substance. The petroleum proppant enters the formation along with the high-pressure solution and fills in the cracks in the rock formation to play a role in supporting the cracks from closing. The cracks in the rock formation will close due to the release of pressure, affecting the production of oil and gas. After filling with the proppant, the oil and gas channels are unobstructed, which can increase the production of oil and gas. When producing petroleum fracturing sand, it is often necessary to use a raw sand screening device for petroleum fracturing sand to screen the petroleum fracturing sand.

[0003] Prior art includes a utility model with publication number CN217726222U, which discloses a fracturing sand filtering device for petroleum fracturing experiments. The patent adopts a main body mechanism, which includes: a filter box, a mixing component arranged inside the filter box, a filter plate arranged inside the filter box, a first filter hole arranged inside the filter plate, an anti-clogging component arranged inside the filter box, and a screening component arranged at the bottom of the filter box, the anti-clogging component includes a support rod arranged inside the filter box, a cylinder arranged at the top of the support rod, a support frame arranged at the top of the cylinder, and a push rod arranged at the top of the support frame; the utility model device solves the problem that when the first drive motor drives the cam to rotate, so that the cam drives the filter cartridge to swing and filter through the first connecting plate and the transmission shaft, the holes on the filter cartridge are prone to blockage, resulting in poor subsequent filtering effect.

[0004] The inventors found in their daily work that during the material screening process, materials accumulate in the middle of the filter screen. When the equipment is running, the accumulated materials are difficult to screen quickly. At the same time, the accumulated materials easily cause downward pressure and deformation of the filter screen. Utility Model Content

[0005] The utility model aims to solve the defect in the prior art that the filter screen is deformed due to the accumulation of materials on the surface of the filter screen, and proposes a raw sand screening device for petroleum fracturing sand.

[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a raw sand screening device for petroleum fracturing sand, comprising a base and a stirring device, the upper surface of the base is fixedly connected to a vibrator, the upper end of the vibrator is provided with a tank body, the upper end of the tank body is fixedly connected to a feed hopper, the side of the tank body is fixedly connected to a discharge end, the stirring device is arranged inside the tank body, the stirring device comprises a connecting frame and a motor, the connecting frame is fixedly connected to the connection between the feed hopper and the tank body, the motor is fixedly connected to the inside of the connecting frame, the output end of the motor is fixedly connected to a rotating column, and the surface of the rotating column is fixedly connected to a connecting rod.

[0007] Furthermore, the inner wall of the tank body is fixedly connected with a slide rail, and a slide groove is provided on the surface of the slide rail. By setting the slide rail, the limit rod can be limited, thereby reducing the risk of shaking when the rotating column rotates during use of the equipment, which makes it difficult for the striking block to rotate smoothly.

[0008] Furthermore, a limiting rod is fixedly connected to the surface of the rotating column, and the limiting rod is slidably connected to the inner wall of the sliding groove. The limiting rod is provided to facilitate limiting the rotating column.

[0009] Furthermore, a striking block is fixedly connected to the surface of the connecting rod and the limiting rod, and a passing hole is provided on the surface of the striking block, and the passing hole is provided to facilitate the passage of materials.

[0010] Furthermore, a protective device is provided on the surface of the motor, and the protective device includes a protective cover and an elastic rod. The protective cover is provided on the surface of the motor, and the elastic rod is fixedly connected to the surface of the connecting frame. A connecting block is fixedly connected to the side of the protective cover. By providing the protective cover, the motor can be protected, thereby reducing the risk of the tail end of the motor being easily impacted by materials when the equipment is in use, thereby causing damage to the motor.

[0011] Furthermore, a connecting hole is opened on the side of the connecting block, and the elastic rod is engaged with the inside of the connecting hole. The elastic rod is provided to facilitate the restriction of the protective cover.

[0012] Compared with the prior art, the advantages and positive effects of the utility model are:

[0013] 1. In the utility model, when the equipment is in use, the operator passes the material to be screened into the material hopper, and then starts the equipment to screen the material. When the equipment is in use, the user starts the motor, and then the motor rotates to drive the rotating column to rotate. When the rotating column rotates, it drives the limit rod to slide inside the slide slot. The rotation of the rotating column drives the connecting rod to rotate, and the rotation of the connecting rod drives the striking block to rotate to level the material. By setting a stirring device, the material is effectively stirred, which plays a role in stirring the material, reduces the accumulation of materials in the middle of the filter screen when the equipment is in use. When the equipment is running, the accumulated materials are difficult to screen quickly. At the same time, the accumulation of materials easily causes the filter screen to be pressed down and deformed, thereby improving the practicability of the equipment.

[0014] 2. In the utility model, by setting a protective device, when the equipment is in use, the user presses the elastic rod, and then the elastic rod is bent by the pressure and separated from the connecting hole, and then the protective cover loses its restraint, and the protective cover is pulled to drive the connecting block to separate from the surface of the motor, and the protective cover is replaced. By setting a protective device, the motor is effectively protected, which plays a role in protecting the motor, reduces the possibility that the motor is easily impacted by materials when the equipment is in use, causing damage to the inside of the motor and making it difficult to operate, and improves the practicability of the equipment.

[0022] The specific arrangement and function of the stirring device 6 and the protective device 7 will be described in detail below.

[0023] In this embodiment: the stirring device 6 is arranged inside the tank body 3, and the stirring device 6 includes a connecting frame 61 and a motor 66. The connecting frame 61 is fixedly connected to the connection between the feed hopper 4 and the tank body 3, and the motor 66 is fixedly connected to the inside of the connecting frame 61.

[0024] Specifically, a slide rail 68 is fixedly connected to the inner wall of the tank body 3 , and a slide groove 69 is formed on the surface of the slide rail 68 .

[0025] In this embodiment: by setting the slide rail 68, the limit rod 67 can be limited, which reduces the shaking of the rotating column 62 when the equipment is in use, making it difficult for the striking block 64 to rotate smoothly.

[0026] Specifically, a limiting rod 67 is fixedly connected to the surface of the rotating column 62 , and the limiting rod 67 is slidably connected to the inner wall of the sliding groove 69 . The limiting rod 67 is provided to facilitate limiting the rotating column 62 .

[0027] Specifically, the surfaces of the connecting rod 63 and the limiting rod 67 are fixedly connected with a striking block 64 , and a passing hole 65 is provided on the surface of the striking block 64 . The passing hole 65 is provided to facilitate the passage of materials.

[0028] In this embodiment: a protective device 7 is provided on the surface of the motor 66, and the protective device 7 includes a protective cover 71 and an elastic rod 72. The protective cover 71 is provided on the surface of the motor 66, the elastic rod 72 is fixedly connected to the surface of the connecting frame 61, and a connecting block 73 is fixedly connected to the side of the protective cover 71.

[0029] In this embodiment, the protective cover 71 is provided to protect the motor 66, thereby reducing the risk of the tail end of the motor 66 being easily impacted by materials when the device is in use, thereby reducing the risk of damage to the motor 66.

[0031] Working principle: When the equipment is in use, the operator passes the material to be screened into the material hopper, then starts the equipment to screen the material. When the equipment is in use, the user starts the motor 66, and then the motor 66 rotates to drive the rotating column 62 to rotate. When the rotating column 62 rotates, it drives the limit rod 67 to slide inside the slide groove 69.

By setting up the stirring device 6, the material is effectively stirred, which plays a role in stirring the material, reducing the accumulation of materials in the middle of the filter screen when the equipment is in use. When the equipment is running, the accumulated materials are difficult to screen quickly.
