Abstract
Description
Technical Field
[0001] This utility model relates to the field of quartz sand processing technology, and in particular to a quartz sand acid washing system. Background Technology
[0002] Quartz sand is widely used in glass manufacturing, electronic semiconductors, ceramics production, and chemical industries. However, natural quartz sand often contains impurities such as iron, aluminum, titanium oxides, and clay, which severely affect its physicochemical properties and limit its applications. Acid washing is a key process for removing impurities from quartz sand. It involves a chemical reaction between acid and impurities, dissolving or converting them into soluble substances, thus purifying the quartz sand. However, existing quartz sand acid washing systems have certain drawbacks. For example, Chinese patent CN 208728159 U discloses an automatic quartz sand acid washing system. While this device can clean quartz sand, the sand separates from the acidic detergent before being thoroughly cleaned, resulting in incomplete cleaning. A large amount of unreacted acid is discharged, increasing costs and polluting the environment. Furthermore, it consumes a large amount of water and struggles to completely remove residual acid from the quartz sand surface, affecting product quality. It also generates a large amount of acidic wastewater, leading to high treatment costs. Utility Model Content
[0003] This invention proposes a quartz sand acid washing system to solve the problems of high operating costs and large water consumption of existing acid washing devices.
[0004] To achieve the above objectives, this utility model provides the following technical solution: a quartz sand acid washing system, including a support member, on which a cleaning member is rotatably connected along an axis parallel to the horizontal plane. The cleaning member includes a tank body, the interior of which forms a cavity for containing quartz sand. A feed section for adding quartz sand, water, and acidic detergent is fixedly connected to the tank body, as well as a discharge section for discharging the added quartz sand, water, and acidic detergent. A stirring member for stirring the quartz sand is installed on the cleaning member, and part of the stirring member is located inside the cavity.
[0005] Preferably, the stirring component includes a rotating rod, which is rotatably connected to the interior of the cavity, and a plurality of side rods are fixedly connected to one side of the circumference of the rotating rod, with flaps fixedly connected to both sides of the side rods symmetrically.
[0006] Preferably, the tank body includes a tank body, and a feed pipe, a first liquid inlet pipe and a second liquid inlet pipe are fixedly connected to the top of the tank body, with the feed pipe located on one side of the first liquid inlet pipe and the second liquid inlet pipe;
[0007] The bottom of the tank is fixedly connected to a bottom pipe, and a discharge pipe and a liquid discharge pipe are symmetrically fixedly connected to the circumference of the bottom pipe. Valves are installed on the discharge pipe, the liquid discharge pipe, the feed pipe, the first liquid inlet pipe and the second liquid inlet pipe. A filter screen is installed inside the liquid discharge pipe. A feeding hopper is fixedly connected to the feed end of the feed pipe.
[0008] Preferably, a synchronously rotating auger is fixedly connected to the bottom of the rotating rod, and the auger is located inside the bottom tube.
[0009] Preferably, a second motor is fixedly connected to the top of the tank, and the output end of the second motor is connected to the rotating rod.
[0010] Preferably, a pH meter is fixedly connected to one side of the tank, and the detection head of the pH meter is located inside the tank.
[0011] Preferably, the support includes a base, with two support plates symmetrically fixedly connected to the top of the base, and connecting shafts fixedly connected to both sides of the symmetrical periphery of the tank. The two connecting shafts are rotatably connected to opposite sides of the two support plates, and a first motor is fixedly connected to one of the support plates, with the output end of the first motor connected to the connecting shaft.
[0012] The technical effects and advantages provided by this utility model in the above technical solution are as follows:
[0013] (1) When in use, the quartz sand and pickling detergent are added to the inside of the tank through the feeding part. The tank rotates horizontally relative to the support part, so that the quartz sand and pickling detergent are tumbled back and forth, thereby improving the cleaning efficiency of the quartz sand, avoiding the separation of the quartz sand from the acid detergent before it is thoroughly cleaned, making the cleaning more thorough, avoiding the discharge of a large amount of unreacted acid, reducing costs and avoiding environmental pollution.
[0014] (2) Acidic detergent and water are added through the first inlet pipe and the second inlet pipe respectively. After the acidic detergent cleans the quartz sand, water is added into the tank. The first motor drives the connecting shaft and the tank to rotate around the support plate, so that the tank drives the water and quartz sand to tumble back and forth, thereby allowing the water to continuously clean the quartz sand. The water consumption is small, which can more thoroughly clean the acid residue on the surface of the quartz sand, avoid affecting the product quality, and at the same time, it will not generate a large amount of acidic wastewater, further reducing the treatment cost.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.
[0023] like Figures 1-5 As shown, a quartz sand acid washing system includes a support member 1. A cleaning member 2 is rotatably connected to the support member 1 along an axis parallel to the horizontal plane. The cleaning member 2 includes a tank part, the inside of which forms a cavity for containing quartz sand. A feed part for adding quartz sand, water and acid detergent and a discharge part for discharging the added quartz sand, water and acid detergent are fixedly connected to the tank part. An agitator 3 for stirring quartz sand is installed on the cleaning member 2, and part of the agitator 3 is located inside the cavity.
[0024] With the above technical solution, when cleaning quartz sand, quartz sand is added to the inside of the tank through the feeding section, and then acidic detergent is added to the inside of the tank through the feeding section. The tank rotates relative to the support member 1, thereby cleaning the quartz sand inside the tank with the acidic detergent. During the quartz sand cleaning, the agitator 3 stirs the quartz sand inside the cavity, making the quartz sand cleaning more efficient. After the quartz sand is cleaned, the acidic detergent is discharged through the discharge section, and water is added through the feeding section. The water washes away the residual acidic detergent inside the cavity. During the secondary cleaning of the quartz sand, the tank rotates relative to the support member 1, allowing the water to repeatedly clean the quartz sand. During the water cleaning of the quartz sand, the agitator 3 stirs the quartz sand, making the water cleaning of the quartz sand more efficient. After the water cleans the quartz sand, the water is discharged through the discharge section, and then the quartz sand is discharged through the discharge section, thus completing the quartz sand cleaning process.
[0025] Specifically, in one embodiment, regarding the aforementioned stirring element 3, as... Figure 1 , Figure 2 and Figure 5 As shown, the stirring component 3 includes a rotating rod 32, which is rotatably connected to the inside of the cavity. Multiple side rods 33 are fixedly connected to one side of the circumference of the rotating rod 32, and flaps 34 are fixedly connected to both sides of the side rods 33 symmetrically.
[0026] In this embodiment, when the quartz sand is being cleaned, the rotating rod 32 rotates inside the cavity, causing the side rod 33 and the flap 34 to rotate. The flap 34 then flips the quartz sand, making the quartz sand cleaning process more efficient.
[0027] Furthermore, in this utility model, regarding the aforementioned tank portion, as follows: Figure 1 , Figure 2 and Figure 4 As shown, the tank body includes a tank body 21, and a feed pipe 26, a first liquid inlet pipe 29 and a second liquid inlet pipe 210 are fixedly connected to the top of the tank body 21. The feed pipe 26 is located on one side of the first liquid inlet pipe 29 and the second liquid inlet pipe 210.
[0028] A bottom pipe 24 is fixedly connected to the bottom of the tank body 21. A discharge pipe 25 and a liquid discharge pipe 211 are symmetrically fixedly connected to the circumference of the bottom pipe 24. Valves 28 are installed on the discharge pipe 25, the liquid discharge pipe 211, the feed pipe 26, the first liquid inlet pipe 29 and the second liquid inlet pipe 210. A filter screen is installed inside the liquid discharge pipe 211. A feeding hopper 27 is fixedly connected to the feed end of the feed pipe 26.
[0029] In this embodiment, when cleaning quartz sand, valve 28 on the feed pipe 26 is opened, and quartz sand is added through the feeding hopper 27. The quartz sand is guided to the tank 21 through the feed pipe 26. After the quartz sand is added, valve 28 on the feed pipe 26 is closed, and valve 28 on the first liquid inlet pipe 29 is opened. Acidic detergent is then introduced through the first liquid inlet pipe 29. After the acidic detergent is added to the tank 21, valve 28 on the first liquid inlet pipe 29 is closed. The tank 21 rotates around the support member 1, causing the tank 21 to repeatedly agitate the quartz sand inside, thus allowing the acidic detergent to repeatedly clean the quartz sand. The quartz sand is cleaned by the acidic detergent. After washing, open valve 28 on drain pipe 211 to discharge the pickling detergent, and open valve 28 on second inlet pipe 210 to add water. After the water is added into tank 21, close valve 28 on second inlet pipe 210. Rotate tank 21 around support 1 to agitate the quartz sand inside, allowing the water to repeatedly wash the quartz sand. After the quartz sand is washed by the water, open valve 28 on drain pipe 211 to discharge the water, and open valve 28 on bottom pipe 24 to discharge the washed quartz sand from inside tank 21.
[0030] Furthermore, in this invention, to facilitate the discharge of the washed quartz sand, such as... Figure 5 As shown, a synchronously rotating auger 35 is fixedly connected to the bottom of the rotating rod 32, and the auger 35 is located inside the bottom tube 24.
[0031] In this embodiment, the rotating rod 32 rotates inside the cavity, causing the side rod 33 and the flap 34 to rotate. The flap 34 flips the quartz sand, and the rotating rod 32 simultaneously drives the auger 35 to rotate. The auger 35 moves the quartz sand, allowing it to be discharged more quickly through the bottom pipe 24 and the discharge pipe 25, thereby improving the discharge efficiency of the quartz sand.
[0032] Additionally, regarding how the rotating rod 32 rotates, as follows: Figure 1 , Figure 2 and Figure 5 As shown, a second motor 31 is fixedly connected to the top of the tank body 21, and the output end of the second motor 31 is connected to the rotating rod 32.
[0033] In this embodiment, when it is necessary to drive the rotating rod 32 to rotate, the second motor 31 works to drive the rotating rod 32 to rotate, which in turn drives the side rod 33 and the flip plate 34 to rotate, thereby turning the quartz sand.
[0034] Furthermore, after personnel clean the quartz sand, to ensure that no acidic detergent residue remains inside the equipment, such as... Figure 4As shown, a pH meter 23 is fixedly connected to one side of the tank 21, and the detection head of the pH meter 23 is located inside the tank 21.
[0035] In this embodiment, when personnel clean the quartz sand with water, the pH value of the water inside the tank 21 is observed by pH meter 23 to determine whether there is any residual acid washing agent inside the tank 21, thus ensuring a more thorough cleaning of the quartz sand.
[0036] Specifically, in one embodiment, regarding the aforementioned support member 1, as... Figures 1-3 As shown, the support member 1 includes a base 11, and two support plates 12 are symmetrically fixedly connected to the top of the base 11. Two connecting shafts 22 are fixedly connected to both sides of the circumference of the tank body 21. The two connecting shafts 22 are rotatably connected to the opposite side of the two support plates 12, and a first motor 13 is fixedly connected to one of the support plates 12. The output end of the first motor 13 is connected to the connecting shaft 22.
[0037] In this embodiment, the base 11 supports the support plate 12, and the support plate 12 supports the connecting shaft 22. When it is necessary to drive the tank 21 to rotate, the first motor 13 works to drive the connecting shaft 22 to rotate, thereby causing the connecting shaft 22 to drive the tank 21 to rotate, and then reciprocating to turn the quartz sand for cleaning.
[0038] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. 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.
