Description

Technical Field

[0001] This utility model belongs to the field of quartz sand production technology, specifically a dehydration device for quartz sand preparation. Background Technology

[0002] After being mined, quartz sand typically undergoes washing and other treatments, resulting in the absorption of a large amount of moisture on its surface and within its internal pores. This moisture not only increases transportation costs but also severely impacts subsequent processing techniques (such as sintering and smelting), leading to problems like increased energy consumption and decreased product quality. Therefore, efficiently removing moisture from quartz sand is a crucial step in improving its quality and production efficiency.

[0003] Currently, centrifugal dehydration is one of the commonly used dehydration methods in the preparation of quartz sand. This method uses centrifugal force to remove water from the quartz sand by driving the centrifuge drum to rotate at high speed. However, existing centrifugal dehydration equipment relies solely on centrifugal force, resulting in low dehydration efficiency. In addition, during the dehydration process, the quartz sand is often in a relatively fixed position inside the centrifuge drum, lacking sufficient positional exchange and disturbance between particles. This prevents some quartz sand from fully contacting the centrifugal force surface, causing uneven dehydration and poor dehydration in some areas. Utility Model Content

The synergistic effect of centrifugal force and vibration further accelerates the removal of water, significantly improving the dewatering efficiency of the quartz sand. Attached Figure Description

[0038] The disturbance mechanism 6 is rotatably installed inside the centrifuge cylinder 2. The disturbance mechanism 6 agitates the quartz sand inside the centrifuge cylinder 2, thereby exchanging the positions of the quartz sand particles.

[0039] The disturbance mechanism 6 and the conveying auger 5 are both connected to the output end of the drive motor 3, and the drive motor 3 synchronously drives the disturbance mechanism 6 and the conveying auger 5.

[0040] It should be noted that the bottom wall of the dehydration shell 1 is provided with a discharge port, and the lower end of the centrifuge cylinder 2 is provided with a sand discharge port. A wireless solenoid valve is installed on the sand discharge port. When the wireless solenoid valve is closed, the dehydrated water is discharged from the discharge port.

[0041] Specifically, see Figure 1 and Figure 3In this embodiment, a sand inlet pipe 7 is rotatably provided on the top wall of the dehydration shell 1, and a sand guide pipe 8 is connected to the upper end of the conveying pipe 4. One of the sand inlet pipe 7 and the sand guide pipe 8 is provided with a positioning protrusion 9, and the other is provided with a positioning groove 10.

[0045] Specifically, see Figure 1 and Figure 2 In this embodiment, a drive housing 15 is provided on the bottom wall of the sand guide pipe 8, and a conveying shaft 16 is rotatably provided on the bottom wall of the drive housing 15.

One end of the conveying auger 5 is rotatably provided in the drive housing 15. An active bevel gear 17 is provided on the conveying shaft 16, and a driven bevel gear 18 is provided on the conveying auger 5. The driven bevel gear 18 and the active bevel gear 17 mesh.

[0046] It should be noted that the top wall of the drive housing 15 is designed with a conical structure to facilitate the downward sliding of quartz sand.

The vibration mechanism is located above the centrifuge cylinder 2 and is connected to the sand guide pipe 8.

[0050] During operation, the sand guide pipe 8 drives the centrifuge cylinder 2 to rotate, which in turn drives the vibration mechanism to strike the centrifuge cylinder 2. Furthermore, the buffer component 24, in conjunction with the vibration mechanism, drives the centrifuge cylinder 2 to vibrate. In other words, the centrifuge cylinder 2 vibrates during the rotation and dewatering process, which improves the dewatering efficiency of the quartz sand.

The first transmission bevel gear 26 and the second transmission bevel gear mesh with each other, and the vibration cam 30 is mounted on the vibration shaft 29.

[0053] During operation, the rotation of the sand guide pipe 8 drives the first transmission bevel gear 26 to rotate. The meshing of the first transmission bevel gear 26 and the second transmission bevel gear drives the vibration shaft 29 to rotate. The vibration shaft 29 strikes the centrifuge cylinder 2, thereby vibrating the centrifuge cylinder 2. The dewatering efficiency of the quartz sand is improved through the vibration and centrifugal action of the rotation of the centrifuge cylinder 2.

[0054] Specifically, see Figure 4In this embodiment, the buffer assembly 24 includes a sleeve 31, a slide rod 32, and a spring 33. The sleeve 31 is connected to the support plate 23. The slide rod 32 is slidably disposed inside the sleeve 31 and connected to the connecting plate 25. The spring 33 is sleeved on the sleeve 31 and the slide rod 32. The two ends of the spring 33 are respectively connected to the support plate 23 and the connecting plate 25. The spring 33, in conjunction with the vibration cam 30, enables the centrifuge cylinder 2 to vibrate up and down.
