Description

Technical Field

[0001] This utility model relates to the field of quartz sand feeding technology, specifically to a uniform quartz sand feeder. Background Technology

[0002] Purification is a crucial step in the production of quartz sand. Natural quartz sand ore contains impurities in addition to quartz sand, often resulting in low purity. Currently, to improve quartz sand purity, a common method is to first heat the quartz sand ore in a furnace, then immerse the hot quartz sand ore in cold water for a cold-explosion treatment, thereby fully exposing the impurities.

[0003] However, certain problems exist in actual operation. When heated quartz stone is directly dropped into the cold water tank, it tends to accumulate at the point of impact, making it impossible to distribute evenly throughout the tank. Furthermore, most existing technologies lack the function of crushing the heated quartz stone, resulting in significant variations in stone size. This is detrimental to subsequent uniform distribution, thus affecting the overall efficiency and effectiveness of quartz sand purification. Therefore, there is an urgent need for a device capable of crushing quartz stone and achieving uniform feeding to improve this situation. Utility Model Content

[0027] The present invention will now be described in further detail with reference to the accompanying drawings.

[0028] Combined with appendix Figure 1 To be continued Figure 6 A quartz sand uniform feeder includes a crushing box 1 with an outlet 7 at the center of its bottom. A mounting base 20 for fixed installation is fixed to the side of the crushing box 1. A feed inlet 13 is connected to the upper feed port of the crushing box 1. An inverted conical crushing chamber 2 is provided inside the crushing box 1, and a cylindrical crushing roller 3 is rotatably mounted inside the crushing chamber 2. A motor 4 for driving the crushing roller 3 is fixed to the upper end of the crushing box 1. A mounting plate 5 is fixed to the outer side of the crushing box 1, and a vertical rod 6 is rotatably mounted on the mounting plate 5. The upper end of the vertical rod 6 is connected to the drive shaft of the motor 4 via a transmission mechanism. The lower end of the vertical rod 6 extends below the crushing box 1 and is fixedly mounted on a circular material distribution plate 8. The circular material distribution plate 8 has several evenly distributed discharge holes 9.

[0029] In this embodiment, as a preferred technical solution, the transmission mechanism includes a drive wheel 10 fixedly sleeved on the drive shaft of the motor 4, and a driven wheel 11 fixedly mounted on the upper end of the vertical rod 6. A belt 12 is provided between the drive wheel 10 and the driven wheel 11.

[0030] In this embodiment, as a preferred technical solution, the bottom of the crushing box 1 is connected to a pusher plate 14 for leveling materials via a height adjustment mechanism. Rake teeth 19 are fixedly installed at the bottom of the pusher plate 14. The height adjustment mechanism includes a telescopic tube 15 fixedly installed at the bottom of the crushing box 1. A connecting rod 16 is inserted and connected to the lower end of the telescopic tube 15. The pusher plate 14 is fixedly installed at the lower end of the connecting rod 16. A fixing bolt 17 is threadedly connected to the side of the telescopic tube 15. Multiple threaded holes 18 that match the fixing bolts 17 are provided on the side of the connecting rod 16. The height of the pusher plate 14 can be adjusted according to actual needs. During the quartz sand falling process, the pusher plate 14 can level and organize the material, further promoting uniform material distribution. Simultaneously, the rake teeth 19 can prevent material blockage, ensuring the continuity and stability of feeding.

[0031] The working principle of this utility model's quartz sand uniform feeder is as follows: After the motor 4 starts, it drives the crushing roller 3 to rotate in the crushing chamber 2, crushing the quartz stone that enters the crushing box 1 from the feed inclined plate 13. At the same time, the drive wheel 10 on the drive shaft of the motor 4 drives the driven wheel 11 at the upper end of the vertical rod 6 to rotate through the belt 12, thereby causing the vertical rod 6 and the circular uniform feed plate 8 at the lower end to rotate. At the bottom of the crushing box 1, the push plate 14 is at a suitable height under the action of the height adjustment mechanism, and the rake teeth 19 at its bottom can prevent material blockage and assist in leveling the material. The crushed quartz sand falls onto the circular uniform feed plate 8 through the outlet 7, and the quartz sand is evenly distributed by the rotation of the uniform feed plate 8 and the evenly distributed discharge holes 9 on it.

[0032] The working process of this utility model's uniform feeder for quartz sand is as follows:

[0033] 1. First, fix the device below the outlet of the heating furnace. The heated quartz sand falls into the feed inclined plate 13 and then slides into the crushing box 1.

[0034] 2. Start motor 4. Motor 4 drives crushing roller 3 to rotate in crushing chamber 2 to crush quartz sand.

[0035] 3. The drive wheel 10 on the drive shaft of the motor 4 rotates, and the driven wheel 11 at the upper end of the vertical rod 6 rotates through the belt 12, so that the vertical rod 6 drives the circular material distribution plate 8 to start rotating.

[0036] 4. The crushed quartz sand falls onto the circular equalization plate 8 through the outlet 7 at the bottom center of the crushing box 1.

[0037] 5. As the circular material distribution disc 8 rotates, the quartz sand is evenly distributed through the discharge holes 9 on the disc 8, completing the uniform feeding process. During this process, the height adjustment mechanism can be adjusted according to actual needs, i.e., the height of the pusher plate 14 can be adjusted through the telescopic tube 15, connecting rod 16, fixing bolt 17 and threaded hole 18. The rake teeth 19 at the bottom of the pusher plate 14 are used to prevent material blockage and assist in leveling the material, ensuring the smooth progress of the entire feeding process.

[0038] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
