Description

Technical Field

[0002] Quartz sand is an important industrial mineral raw material, widely used in glass manufacturing, photovoltaic new energy, precision ceramics, electronic materials and other fields. The quality of high-purity quartz sand directly determines the quality and performance of downstream products. Raw quartz sand ore usually contains impurities such as iron oxide, alumina, and organic matter. The industry commonly uses acid washing to remove surface and pore impurities, followed by purification through water washing. The efficiency, cleanliness, and water resource utilization of the acid washing and washing processes are key factors affecting the purification quality and production cost of quartz sand.

[0003] However, the existing methods for separating and classifying waste acid from quartz sand pickling, as well as acidic wastewater in the initial cleaning stage and clean cleaning water in the middle and later stages, cannot achieve separate discharge. The various liquids mix with each other, which not only makes waste acid recovery difficult and clean water cannot be recycled, resulting in a large waste of water resources, but also significantly increases the subsequent treatment cost of waste liquid.

[0004] In view of this, the present invention is proposed. Summary of the Invention

[0019] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate the present invention.

[0020] Example 1:

[0021] like Figures 1 to 10As shown, an integrated equipment for acid washing reaction and cleaning of quartz sand includes a processing tank 1. Acid inlet pipe 13, acid outlet pipe 131, and clean water inlet pipe 14 and clean water outlet pipe 141 are respectively arranged on both sides of the processing tank 1. A circular fixing ring 15 is also provided inside the processing tank 1. A processing shell 16 is arranged inside the circular fixing ring 15, and a liquid discharge hopper 19 is provided at the bottom of the processing shell 16. A driving assembly is provided on the circular fixing ring 15, which is used to drive the processing shell 16, which is fitted into the circular fixing ring 15. The vertical reciprocating motion of the pump is used to agitate and clean the quartz sand placed in the processing housing 16. A sealing assembly is installed at the bottom of the liquid discharge hopper 19 to seal the filter holes at the bottom of the processing housing 16 and to prevent liquid leakage during the quartz sand reaction. An installation housing 3 is also installed inside the processing tank 1, with rotating components on both sides of the installation housing 3. These rotating components ensure the installation housing 3 can swing and allow pickling solution and clean water to be discharged from both sides of the installation housing 3. The vertical agitation of the quartz sand is achieved through the driving assembly, improving the uniformity of material-liquid contact. The sealing assembly controls the opening and closing of the filter holes to meet the needs of pickling and staged drainage. The rotating assembly allows for bidirectional tilting of the installation housing, and the baffle plate 36 switches the drainage channel, enabling the separate discharge of waste acid, initial wastewater, and clean cleaning water. The clean water from the later stages of cleaning can be recycled, reducing water consumption and effectively improving the overall efficiency of the quartz sand pickling and cleaning operation.

[0022] like Figures 1 to 6 As shown in the specific embodiment, a support 12 is provided at the bottom of the treatment tank 1, and a cover plate 11 is provided on top of the treatment tank 1. An acid inlet pipe 13, an acid outlet pipe 131, a clean water inlet pipe 14, and a clean water outlet pipe 141 are provided through the treatment tank 1. Two rectangular slots 161 are also provided in the inner cavity of the treatment shell 16. The two rectangular slots 161 are opposite each other, and the acid inlet pipe 13 and the clean water inlet pipe 14 are slidably arranged in the two rectangular slots 161 respectively, with their ports located in the inner cavity of the treatment shell 16. The inner cavity of the treatment shell 16 is used to place quartz sand. A conical platform 18 is placed on top of the inner cavity of the treatment shell 16, and a circular slot is provided at the bottom of the treatment shell 16. In this configuration, the support 12 provides stable support for the treatment tank 1, the cover plate 11 can close the top opening of the treatment tank 1, the rectangular slots 161 provide stroke for the extension and sliding of the pipes, and the conical platform 18 can gather the liquid and avoid liquid splashing, ensuring the stable operation of acid washing and cleaning.

[0023] like Figures 1 to 6As shown, the drive assembly further includes four vertical electric slide rails 151, which are respectively disposed on the inner wall of the circular fixing ring 15. The four vertical electric slide rails 151 are circumferentially distributed, and each of the four vertical electric slide rails 151 has a sliding block 152 slidably disposed on it. The ends of the four sliding blocks 152 away from the vertical electric slide rails 151 are disposed on the outer wall of the processing housing 16, and are used to ensure that the processing housing 16 can move vertically. In this configuration, the circumferentially distributed vertical electric slide rails 151 can synchronously drive the sliding blocks 152 to slide vertically, causing the processing housing 16 to rise and fall smoothly without horizontal deviation, realizing uniform shaking of the quartz sand and improving the reaction cleaning effect.

[0024] Example 2:

[0025] The difference between the above embodiments and this embodiment is that: Figures 1 to 7 As shown, an integrated equipment for quartz sand pickling reaction and cleaning includes a sealing component comprising multiple sealing plates 23, each sealing plate 23 being circumferentially distributed and adapted to the filter holes opened at the bottom of the processing housing 16, and used to seal the filter holes. A circular rotating plate 22 is provided on the opposite side of each sealing plate 23.

[0026] like Figures 1 to 7 As shown in the specific embodiment, an annular electric slide rail 2 is provided on the circular slot at the bottom of the processing housing 16. A movable slider 21 is slidably mounted on the annular electric slide rail 2, and a circular rotating plate 22 is provided at the end of the movable slider 21 away from the annular electric slide rail 2. In this configuration, the annular electric slide rail 2 can drive the movable slider 21 to slide in an annular manner, thereby driving the circular rotating plate 22 and the sealing plate 23 to rotate synchronously, realizing the opening and closing of the filter holes and sealing, thus meeting the requirements of acid washing and drainage conditions.

[0027] like Figures 1 to 3 and Figures 7 to 8 As shown, furthermore, a liquid placement shell 17 is placed at the bottom of the inner cavity of the treatment tank 1. The liquid placement shell 17 has an acid outlet 171 and a clean water outlet 172 on its two sides, respectively. The bottom of the inner cavity of the liquid placement shell 17 is conical, and a baffle 38 is provided in the middle of the liquid placement shell 17. In this configuration, the conical structure facilitates rapid liquid collection and discharge, and the baffle 38 separates the acid and clean water flow areas, preventing waste liquid from mixing with cleaning water and ensuring the classified collection and discharge of liquids.

[0028] Example 3:

[0029] The difference between the above embodiments and this embodiment is that: Figures 1 to 3 and Figures 7 to 8As shown, an integrated equipment for quartz sand acid washing reaction and cleaning includes a rotating component including a servo motor 33, which is disposed on the inner wall of the liquid placement housing 17. A rotating rod 331 is disposed at the output end of the servo motor 33. The end of the rotating rod 331 away from the servo motor 33 is disposed on the side wall of the mounting housing 3. A rotating rod 332 is disposed on the side of the liquid placement housing 17 away from the servo motor 33. A mounting bearing 333 is disposed at the other end of the rotating rod 332, which is disposed on the inner wall of the liquid placement housing 17.

[0030] like Figures 1 to 3 and Figures 7 to 9 As shown in the specific embodiment, a rotating ball 32 is rotatably mounted on the top of the mounting housing 3, and an outer sleeve pipe 321 is rotatably mounted on the rotating ball 32. The outer sleeve pipe 321 and the discharge pipe 191 are slidably arranged relative to each other. An acid drain port 371 and a clean water drain port 372 are respectively opened on both sides of the mounting housing 3. In this configuration, the rotating ball 32 cooperates with the outer sleeve pipe 321 to accommodate the swaying and rotation of the mounting housing 3, preventing the discharge pipe 191 from getting stuck. The two drain ports can respectively discharge acid and clean water, achieving separation of waste liquid and clean water.

[0031] like Figures 1 to 3 and Figures 7 to 10 As shown, furthermore, the inner cavity of the mounting housing 3 is also provided with two guide rods 34 and an inclined rod 341. The two guide rods 34 and the inclined rod 341 are integrated into each other, and the guide rods 34 and the inclined rod 341 are respectively set on the inner wall of the mounting housing 3. The two guide rods 34 and the inclined rod 341 are symmetrical to each other, and a movable collar 35 is slidably mounted on the two guide rods 34 and the inclined rod 341. In this configuration, the integrated guide rods 34 and the inclined rod 341 provide a precise sliding trajectory for the movable collar 35, adapting to the tilted state of the mounting housing 3 and ensuring the stable operation of the sliding structure.

[0032] like Figures 1 to 3 and Figures 7 to 10 As shown, furthermore, the bottom of the two movable collars 35 is provided with connecting rods 351, and the bottom of the two connecting rods 351 is provided with baffle plates 36. The baffle plates 36 are used to seal the clean water drain port 372. In this configuration, the movable collars 35 drive the baffle plates 36 to move through the connecting rods 351, which can block or open the clean water drain port 372 according to the working conditions, so as to realize the classified discharge of liquid and self-cleaning of the cavity at different cleaning stages.

[0033] The implementation principle of the integrated quartz sand acid washing reaction and cleaning equipment of the present invention is as follows: In the initial state of the equipment, first open the cover plate 11 on the top of the processing tank 1 to expose the internal cavity of the processing tank 1. The staff can directly fill the quartz sand to be processed into the internal cavity of the processing shell 16 through the opening at the top of the processing shell 16. After the quartz sand is filled, close the cover plate 11 to complete the quartz sand placement process. Acid washing, cleaning and other operations can be carried out afterward. After the material filling and sealing preparation work is completed, the tank body is sealed by the cover plate 11 on the top of the treatment tank 1. Then, the acid washing liquid is injected into the inner cavity of the treatment shell 16 through the acid inlet pipe 13. The acid liquid enters the material area directly through the pipe port that penetrates the rectangular slot 161, completely immersing the internal quartz sand. During the pickling operation, the four vertical electric slide rails 151 distributed circumferentially on the inner wall of the circular fixed ring 15 are started simultaneously, driving each sliding block 152 to slide back and forth in the vertical direction. Relying on the fixed connection between the sliding block 152 and the outer wall of the treatment shell 16, the treatment shell 16 as a whole is driven to perform reciprocating lifting and lowering motion in the vertical direction (during the lifting and lowering process, because the treatment shell 16 and the treatment tank 1 are sealed by a PTFE spring energy storage plug, which is an existing technical solution, it will not be described in detail here), the internal quartz sand continuously shakes up and down with the shell, which greatly improves the uniformity of contact between the quartz sand and the acid solution, effectively accelerates the pickling reaction rate of impurities on the surface of the quartz sand, and improves the pickling and impurity removal effect; After the pickling process is completed, the annular electric slide rail 2 is run, which drives the moving slider 21, the circular rotating plate 22 and the sealing plate 23 to rotate as a whole, releasing the sealing limit on the bottom filter hole of the treatment housing 16. At this time, the waste acid liquid in the treatment housing 16 can drip down through the bottom filter hole and the liquid discharge hopper 19 and flow into the inner cavity of the installation housing 3 {wherein the filter hole diameter is smaller than the minimum particle size of the quartz sand to be treated (wherein when flowing into the installation housing 2: the rotating ball 32 set above it is set together with the installation housing 2 and the outer pipe 321 by the spherical joint seat, the spherical sealing ring, the telescopic sleeve sealing ring and the limiting ring, etc., and the specific connection method is the existing technology, so it cannot prevent liquid leakage)}; While the waste acid is being discharged into the inner cavity of the mounting housing 3, the servo motor 33 starts running synchronously. The rotating rod 331 drives the entire mounting housing 3 to rotate. With the auxiliary support of the rotating rod 332 and the mounting bearing 333, the mounting housing 3 switches to the working state opposite to that shown in the figure. This ensures that the waste acid can flow from the acid drain port 371 on the mounting housing 3 into the liquid placement housing 17 below. After the waste acid enters the liquid placement housing 17, it connects to the acid outlet pipe 131 through the acid outlet 171 on the side wall of the liquid placement housing 17, and is finally discharged out of the equipment through the acid outlet pipe 131.

[0034] After the waste liquid is completely discharged, the equipment does not reset (and the sealing component does not reset, so the filter hole at the bottom of the treatment shell 16 will not be sealed). Then, clean water is injected into the inner cavity of the treatment shell 16 through the clean water inlet pipe 14 to rinse the acid-washed quartz sand (the clean water inlet pipe 14 is equipped with a spray head to ensure that clean water can be sprayed onto the entire cavity of the treatment shell 16). Simultaneously, the drive component drives the treatment shell 16 to swing vertically back and forth, allowing the clean water to fully wash away the residual acid and impurities on the surface of the quartz sand, achieving efficient cleaning operation. In the initial stage of cleaning: clean water will enter the inner cavity of the mounting housing 3. However, because the clean water contains a large amount of acid, it is considered wastewater and will be discharged from the pickling solution (this is the working principle described above). During the middle stage of cleaning, when the acid in the quartz sand is almost gone, the operator controls the rotating component to return to the state shown in the attached diagram. As a result, clean water enters the mounting housing 3 and then exits through the clean water drain port 372 on the mounting housing 3. Because the mounting housing 3 changes its tilting position at this time, the baffle plate 36 in the inner cavity of the mounting housing 3 can slide down to the clean water drain port 372 with the assistance of the tilting rod 341 and the guide rod 34. During this process, the cleaning fluid from the middle stage of cleaning can be discharged from the clean water drain port 372 on the mounting housing 3. The discharged clean water can be collected and used in the initial stage of the next acid cleaning, thus saving water. In the later stages of cleaning, when the quartz sand no longer contains acid, the baffle plate 36 seals the clean water drain port 372, ensuring that the clean water from the later cleaning process remains inside the mounting housing 3. This allows the mounting housing 3 to be soaked and cleaned. After the acid washing and cleaning of the quartz sand are completed, the cover plate 11 is opened, and the quartz sand is removed. At this time, the operator controls the rotating component to reset the mounting housing 3 to the state where the acid is discharged, allowing the clean water to clean the liquid placement housing 17 and drain it. The drained clean water is collected and can be used in the initial stage of the next acid washing or in the middle stage of the cleaning process, thus saving water.

[0035] Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention 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.
