Technical Field

[0001] The utility model relates to a quartz sand pickling upper barrel, belonging to the technical field of quartz sand purification. Background Art

[0002] Quartz sand is quartz particles made by crushing quartz stone. It is also a non-metallic mineral and a hard, wear-resistant, chemically stable silicate mineral. It is milky white or colorless and translucent, with a Mohs hardness of 7. Quartz sand is an important industrial mineral raw material and a non-chemical hazardous substance. It is widely used in industries such as glass, casting, ceramics and fireproof materials, smelting ferrosilicon, metallurgical solvents, metallurgy, construction, chemicals, plastics, rubber, abrasives and filter materials.

[0003] In the production of quartz sand, pickling is a key step used to remove impurities and improve its purity. Currently, pickling of quartz sand is mostly done by placing the raw quartz sand into a pickling tank and then adding an acidic solution. Some acidic liquids can corrode stainless steel tanks, so to minimize losses during pickling, quartz sand and acidic solutions are loaded into PE barrels. However, traditional pickling equipment often suffers from low efficiency, unstable structure, significant environmental impact, and high operator safety risks. Summary of the Invention

[0006] Moreover, the circular movable screen plate and filter plate are concave from the edge to the center, which is convenient for the discharge of quartz sand and acidic wastewater after pickling.

[0007] Moreover, there are 16 uniformly distributed stiffeners at the bottom of the barrel, evenly arranged on the inner wall of the barrel, which are used to strengthen the overall structure of the pickling barrel and maintain its stability and strength when subjected to internal pressure and external loads.

[0017] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments, but the protection scope of the present invention is not limited to the following embodiments.

[0018] In the technical solution provided by the present invention, a quartz sand pickling upper barrel is provided, and its overall structure is as follows: Figure 1As shown, it at least includes a barrel body and a barrel cover. The barrel body of the pickling upper barrel is a hollow cylinder as a whole, and the barrel cover is a round shape as a whole, which matches the barrel body; the barrel cover is provided with a sand inlet 1, an inspection port 2, a water pipe 3, a spray pipe 4, an acid inlet pipe 5 and an exhaust pipe 6; the sand inlet 1 is funnel-shaped and located in the center of the barrel cover, and the inspection port 2, the water pipe 3, the spray pipe 4, the acid inlet pipe 5 and the exhaust pipe 6 are arranged around the sand inlet 1 and located at the edge of the barrel cover; a uniformly distributed stiffener 7 is provided at the bottom of the barrel body, and a circular movable screen plate 10 and a filter plate 11 are provided above the uniformly distributed stiffener 9; a sand discharge port 7 is provided in the center of the movable screen plate 10 and the filter plate 11 for discharging quartz sand after pickling; an acid discharge port 8 is provided on the left side of the sand discharge port 7 for discharging acidic wastewater after pickling.

[0019] Moreover, the circular movable screen plate 10 and filter plate 11 are recessed from the edge to the center, which facilitates the discharge of the quartz sand and acidic wastewater after pickling.

[0020] Moreover, there are 16 uniformly distributed stiffeners 9 at the bottom of the barrel body, which are evenly arranged on the inner wall of the barrel body to strengthen the overall structure of the pickling barrel and maintain its stability and strength when subjected to internal pressure and external loads.

[0021] Moreover, the filter plate 11 is provided with 1000 evenly distributed filter holes, and the filter holes are circular holes with a diameter of 10 mm.

[0022] Moreover, the upper thickness of the pickling upper barrel body is 40mm, the lower thickness is 60mm, the bottom thickness of the pickling upper barrel is 35mm, and the barrel cover is 20mm thick.

[0023] In this embodiment, the funnel-shaped sand inlet and the surrounding spray pipes 4 and acid inlet pipes 5 ensure that the acid and water evenly cover the quartz sand, improving pickling efficiency and sand treatment quality. Sixteen uniformly spaced stiffeners 9 are located at the bottom of the barrel. These stiffeners are evenly arranged along the inner wall of the barrel, significantly enhancing the overall structural strength of the barrel, enabling it to withstand greater internal pressure and external loads, ensuring the stability and long-term durability of the equipment. The movable screen plate 10 and filter plate 11 are recessed from the edges toward the center.

This design ensures effective filtration of impurities in the quartz sand while preventing excessive sand loss, ensuring the efficiency of the pickling process and the purity of the quartz sand. The upper thickness of the pickling barrel is 40mm, the lower thickness is 60mm, the bottom thickness is 35mm, and the barrel cover thickness is 20mm. These thick designs make the barrel body have excellent corrosion resistance and mechanical strength, suitable for long-term, high-intensity working environment.

[0024] The upper barrel design of this utility model takes into account the convenience of operation. Through the rational layout of pipes and interfaces, operators can easily perform acid addition, water addition, and subsequent pickling treatment, reducing operational difficulty and improving work efficiency. In addition, through effective acid and water resource management, environmental pollution is reduced. In particular, the special acid discharge port and filter plate design reduce the negative impact on the environment and meet the requirements of green and environmentally friendly production.

[0025] In summary, the quartz sand pickling upper barrel of the utility model has significant advantages in improving pickling efficiency, ensuring quartz sand treatment quality, enhancing equipment stability and durability, simplifying operation procedures and environmental protection, and is very suitable for use in large-scale quartz sand production.
