DETAILED DESCRIPTION

[0022] As Figures 1-5 shown, the utility model provides a technical scheme: a kind of double-layer vibrating screening device for quartz sand preparation, including screening box 1, screening box 1 is provided with feed inlet 2, quartz sand material is poured into the inside of screening box 1 by feed inlet 2, motor 3 is fixedly installed on screening box 1, rotating rod 4 is fixedly connected on the output end of motor 3, first screening plate 5 and second screening plate 6 are respectively provided on the inner wall of screening box 1, stirring rod 7 is fixedly installed on the outer wall of rotating rod 4, rotating rod 4 outer wall stirring rod 7 is driven to rotate by starting motor 3, which can stir quartz sand and speed up screening, rotating rod 4 outer wall is provided with scattering mechanism 8, and stirring mechanism 9 is provided on stirring rod 7.

[0023] In the embodiment, rotating rod 4 outer wall is provided with scattering mechanism 8, material falling from feed inlet 2 can be scattered by the rotation of scattering disc 82 in scattering mechanism 8, the inclined groove 83 is opened in the scattering disc 82, which facilitates the diffusion of the material around the scattering disc 82, and the leakage hole 84 is opened in the inclined groove 83, which facilitates the flow of the material in the inclined groove 83 while uniformly leaking down, so that the material can be uniformly scattered into the inside of the screening box 1 for screening.

[0024] In the embodiment, stirring mechanism 9 is provided on stirring rod 7, centrifugal force is generated by the rotation of gravity block 91 in stirring mechanism 9, which can make gravity block 91 drive stirring blade 94 at the end of connecting rod 93 to elongate, and the elastic force of tension spring 92 can make connecting rod 93 drive stirring blade 94 to reset, and the extension and retraction of stirring blade 94 during rotation further prevents the accumulation of internal material.

[0025] The aforementioned dispersing mechanism 8 includes a sleeve 81, which is slidably sleeved on the outer wall of the rotating rod 4. A dispersing disc 82 is fixedly installed on the outer wall of the sleeve 81. The dispersing disc 82 is umbrella-shaped. The rotating rod 4 drives the dispersing disc 82 on the outer wall of the sleeve 81 to rotate, which can disperse the material falling from the feed inlet 2. The dispersing disc 82 has inclined grooves 83, which facilitate the diffusion of material to the surrounding area of ​​the dispersing disc 82. The inclined grooves 83 are arranged in an array on the dispersing disc 82. The inside of the inclined grooves 83 has drainage holes 84, which facilitate the flow of material inside the inclined grooves 83. The material is discharged evenly. A bearing spring 85 is sleeved on the outer wall of the rotating rod 4. One end of the bearing spring 85 is fixedly connected to the inner wall of the sleeve 81, and the other end of the bearing spring 85 is fixedly connected to the outer wall of the rotating rod 4. The elastic force of the bearing spring 85 can make the sleeve 81 move upward and reset. A cam 86 is fixedly installed on the outer wall of the sleeve 81, and a hemisphere 87 is fixedly installed on the inner wall of the screening box 1. The hemisphere 87 is located above the cam 86. The sleeve 81 drives the cam 86 on the outer wall to rotate and be squeezed by the hemisphere 87 above. This allows the sleeve 81 to drive the dispersing disc 82 on the outer wall to move up and down continuously while rotating, making the discharge more even.

[0026] The aforementioned stirring mechanism 9 includes a gravity block 91, which is slidably connected to the inner wall of the stirring rod 7. The stirring rod 7 drives the gravity block 91 on the inner wall to rotate, generating centrifugal force, which enables the gravity block 91 to drive the connecting rod 93 to move outward from the stirring rod 7. The side wall of the gravity block 91 is fixedly connected to one end of the tension spring 92, and the other end of the tension spring 92 is fixedly connected to the inner wall of the stirring rod 7. The elastic force of the tension spring 92 enables the connecting rod 93 to drive the stirring blade 94 to reset. The side wall of the gravity block 91 is fixedly connected to one end of the connecting rod 93, and the stirring blade 94 is fixedly installed on the other end of the connecting rod 93. The stirring blade 94 can prevent the accumulation of internal materials by extending and retracting during rotation.

[0027] In this embodiment, quartz sand is poured into the screening box 1 through the feed inlet 2. Then, the motor 3 drives the stirring rod 7 on the outer wall of the rotating rod 4 to rotate, stirring the quartz sand and accelerating screening. Simultaneously, the rotating rod 4 drives the dispersing disc 82 on the outer wall of the sleeve 81 to rotate, dispersing the material falling from the feed inlet 2. The inclined groove 83 on the dispersing disc 82 facilitates the diffusion of material around the disc, making dispersal easier. The inclined groove 83 has a leakage hole 84 inside, allowing material to flow evenly within the groove 83 and be evenly distributed into the screening box 1 for screening. Simultaneously, the sleeve 81 drives the cam 86 on its outer wall to rotate, which is then pressed by the upper hemisphere 87, causing the cam 86 to drive the sleeve... 81 moves downwards, and then the elastic force of the bearing spring 85 causes the sleeve 81 to move upwards and reset. This causes the sleeve 81 to drive the dispersing disc 82 on the outer wall to rotate and move up and down continuously, making the unloading more uniform. The rotating rod 4 drives the stirring rod 7 on the outer wall to rotate. The stirring rod 7 drives the gravity block 91 on the inner wall to rotate, generating centrifugal force. This causes the gravity block 91 to drive the connecting rod 93 to move outwards from the stirring rod 7. This causes the connecting rod 93 to drive the stirring blade 94 at the end to extend. When the rotation speed of the rotating rod 4 decreases, the elastic force of the tension spring 92 causes the connecting rod 93 to drive the stirring blade 94 to reset. This causes the stirring blade 94 to extend and retract during rotation, further preventing the accumulation of internal materials. After screening, the material is discharged through the discharge port on the side wall of the screening box 1.

[0028] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
