[0001] This utility model relates to the technical field of pickling equipment, and in particular to a pickling equipment for quartz sand processing. Background Technology

[0002] Quartz sand is quartz particles produced by crushing and processing quartz stone. Quartz stone is a non-metallic mineral, a hard, wear-resistant, and chemically stable silicate mineral. It is an important industrial mineral raw material, a non-hazardous chemical, and is widely used in glass, casting, ceramics and fireproof materials, ferrosilicon smelting, metallurgical flux, metallurgy, construction, chemical industry, plastics, rubber, abrasives, filter media and other industries. In the processing of quartz sand, it is often necessary to remove impurities by acid washing.

Detailed Implementation

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," "sleeved / connected," "connected," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0019] Example 1: Reference Figure 1-4The illustrated pickling apparatus for quartz sand processing includes a fixed cylinder 1, which serves as the main structure of the entire apparatus, accommodating and supporting other components and providing a closed space for the pickling process. A filter plate 14 is fixedly connected to the inner wall of the fixed cylinder 1. The filter plate 14 separates the quartz sand and acid during the pickling process. The acid flows out through the filter plate 14, while the quartz sand is trapped above it, achieving solid-liquid separation. An upper stirring assembly is installed inside the fixed cylinder 1. This upper stirring assembly includes a rotating plate 8 installed inside the fixed cylinder 1. The rotating plate 8 rotates under the drive of a motor 2, which in turn drives other connected components to move, enabling the stirring assembly to stir the quartz sand. Multiple deflecting plates 9 are fixedly connected to the outer side of the rotating plate 8. As the rotating plate 8 rotates, the deflecting plates 9 change the trajectory of the quartz sand within the fixed cylinder 1, making its distribution more uniform and improving the pickling effect. Multiple deflection plates 9 are rotatably connected to their bottoms by rotating gears 11. These gears 11 rotate under the drive of transmission gears 10, thereby causing the fixed rod 12 to rotate. A fixed rod 12 is fixedly connected to the outer side of the rotating gear 11. The fixed rod 12 connects the rotating gear 11 and the connecting plate 16, transmitting the rotation of the rotating gear 11 to the connecting plate 16. One end of the fixed rod 12 is fixedly connected to the connecting plate 16, which connects the fixed rod 12 and the positioning rod 17, allowing the positioning rod 17 to move with the rotation of the fixed rod 12. A positioning rod 17 is fixedly connected to the outer side of the connecting plate 16. The positioning rod 17 fixes multiple stirring rods 13, enabling them to stir the quartz sand during rotation, increasing the contact area between the quartz sand and the acid solution, and improving the pickling efficiency. Multiple stirring rods 13 are fixedly connected to the outer side of the positioning rod 17. The stirring rods 13 directly stir the quartz sand, causing it to tumble in the acid solution, ensuring that each grain of quartz sand can fully contact the acid solution for better pickling effect. A lower stirring assembly is provided inside the fixed cylinder 1. The lower stirring assembly includes a deflector rod 15 fixedly connected to the rotating plate 8. When the rotating plate 8 rotates, it drives the deflector rod 15 to rotate, which in turn drives the stirring rod 19 to stir the quartz sand below the filter plate 14. Multiple stirring rods 19 are fixedly connected to the outer side of the deflector rod 15. The stirring rods 19 stir the quartz sand remaining below the filter plate 14 to prevent quartz sand accumulation and allow the acid solution to better contact this part of the quartz sand, ensuring comprehensive pickling. The deflector rod 15 passes through the filter plate 14, allowing the lower stirring assembly to stir the quartz sand on both the upper and lower sides of the filter plate 14. A discharge port 18 is provided on the outside of the fixed cylinder 1. The discharge port 18 is used to discharge the treated quartz sand from the fixed cylinder 1 after pickling. A motor 2 is fixedly connected to the top of the fixed cylinder 1. The motor 2 provides power to the stirring components of the entire device. The rotation of the motor 2 drives the rotating plate 8 and other stirring components to work.A fixed gear disc 7 is fixedly connected to the top of the inner wall of the fixed cylinder 1. The fixed gear disc 7 meshes with the transmission gear 10, changing the transmission direction and transmitting power, allowing the rotating gear 11 to rotate in a specific manner. The output end of the motor 2 passes through the fixed cylinder 1 and the fixed gear disc 7, and is fixedly connected to the rotating plate 8. The power output by the motor 2 is directly transmitted to the rotating plate 8, causing it to rotate. A connecting rod 20 is provided on the outer side of the deflection plate 9, passing through the deflection plate 9. The connecting rod 20 connects the two transmission gears 10, ensuring that the two transmission gears 10 can rotate synchronously. Both ends of the connecting rod 20 are fixedly connected to transmission gears 10. One transmission gear 10 meshes with the fixed gear disc 7, and the other transmission gear 10 meshes with the rotating gear 11. Through this meshing relationship, the rotation of the fixed gear disc 7 is transmitted to the rotating gear 11, enabling the rotating gear 11 to rotate, thereby driving the stirring rod 13 to stir the quartz sand.

[0020] Example 2: Reference Figure 1-4 Based on the same concept as Embodiment 1 above, this embodiment also proposes that the fixed cylinder 1 serves as the main supporting part of the entire structure, providing an installation base for other components. The feed pipe 3, fixedly connected to its outer side, is the channel for material to enter the fixed cylinder 1, facilitating the transport of the material to be processed into the fixed cylinder 1 for subsequent operations. Multiple support legs 5 are fixedly connected to the outer side of the fixed cylinder 1, providing stable support and ensuring the fixed cylinder 1 remains stable during placement, preventing it from tipping over. A bottom frame 6 is fixedly connected to the bottom of the fixed cylinder 1, further stabilizing the bottom structure and enhancing the stability of the entire equipment. A hatch 4 is provided on the outer side of the discharge port 18, controlling its opening and closing. When material needs to be discharged from the fixed cylinder 1, the hatch 4 is opened, allowing material to flow out from the discharge port 18; when discharge is not required, the hatch 4 is closed to prevent accidental leakage. A discharge port and a suitable valve are provided at the bottom of the bottom frame 6.

[0021] The working principle of this utility model is as follows: Quartz sand is introduced into the fixed cylinder 1 through the feed pipe 3. The quartz sand is filtered through the filter plate 14, separating large and small pieces of quartz sand into the upper and lower halves of the fixed cylinder 1. The motor 2 drives the rotating plate 8, deflection plate 9, rotating gear 11, fixed rod 12, positioning rod 17, and stirring rod 13 to achieve the revolution of the positioning rod 17 and stirring rod 13. Through the setting of the connecting rod 20 and the transmission gear 10, the rotating gear 11 and the fixed rod 12 achieve rotation during the revolution, so that the positioning rod 17 and stirring rod 13 can stir the large pieces of quartz sand more thoroughly, and the filter plate 14 can filter the quartz sand more thoroughly. During the rotation of the rotating plate 8, the deflection rod 15 drives multiple stirring rods 19 to rotate, stirring the small pieces of quartz sand. Pickling solution is introduced into the feed pipe 3 to separate the large and small pieces of quartz sand for pickling, making the pickling more thorough.

[0022] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
