Description

Technical Field

[0001] This invention relates to the field of acid washing and purification technology, specifically to a high-efficiency acid washing and purification device and process for quartz sand. Background Technology

[0002] Quartz sand, as an important non-metallic mineral resource, is widely used in glass manufacturing, electronic components, building materials, chemicals, metallurgy, and other fields due to its excellent properties such as high temperature resistance, corrosion resistance, high hardness, and good insulation. With the rapid development of downstream industries, the market demand for the purity of quartz sand is increasing, and acid washing purification is one of the core processes for improving the purity of quartz sand.

[0003] Traditional acid pickling and purification equipment typically employs a single-tank structure, directly mixing and reacting quartz sand with acid. After pickling, separation of the quartz sand and acid is achieved through settling or simple filtration. This method suffers from incomplete deacidification, leaving acid residue on the surface of the quartz sand and within the interparticle spaces. This not only increases the workload and difficulty of subsequent cleaning processes but also corrodes the quartz sand particles, affecting product purity and quality. Furthermore, acid discharge and residue cleaning in traditional equipment are often separate processes, requiring additional drive equipment or manual cleaning. This increases equipment manufacturing costs and operating energy consumption, and also leads to incomplete residue removal and severe residue accumulation. Accumulated quartz sand residue hinders sufficient contact between the acid and quartz sand, reducing pickling efficiency and purification effects. It may also clog drainage channels, prolonging the production cycle and increasing the labor intensity of operators. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a high-efficiency acid washing and purification device and process for quartz sand, in order to achieve the above-mentioned objectives.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a high-efficiency acid washing and purification device for quartz sand, comprising: a purification tank, a tank door hinged to the outer side wall of the purification tank, a filter cylinder disposed inside the purification tank, side filter holes and bottom filter holes respectively opened on the outer side wall and bottom wall of the filter cylinder, a sleeve fixedly connected to the middle part of the filter cylinder, a cylinder frame fixedly connected to the upper end of the filter cylinder, a deacidification component disposed at the upper end of the purification tank, and an acid discharge component disposed on the inner wall of the purification tank;

[0006] The deacidification assembly includes a bracket fixedly connected to the upper end of the purification tank. A groove is provided on one side of the bracket. A screw is rotatably connected to the inner wall of the groove. A threaded sleeve is threadedly connected to the outer wall of the screw, and the threaded sleeve is slidably connected to the inner wall of the groove. A mounting plate is fixedly connected to one side of the threaded sleeve. A stirring shaft is rotatably connected to one end of the mounting plate via a rotating shaft. A motor is fixedly connected to the upper end of the bracket, and an output shaft is fixedly connected to the output end of the motor.

[0007] Preferably, the output shaft is cross-shaped, the output shaft is slidably connected to the inner wall of the stirring shaft, and the inner wall of the stirring shaft is provided with a groove adapted to the output shaft.

[0008] Preferably, the acid removal assembly includes a rotating rod rotatably connected to the bottom wall of the purification tank, a connecting rod fixedly connected to the outer side wall of the rotating rod, and three connecting rods evenly spaced. A cleaning plate is fixedly connected to one side of the connecting rod, and three limiting posts are fixedly connected to the upper outer side wall of the rotating rod, and the three limiting posts are arranged in a circumferential array.

[0009] Preferably, the lower end of the cleaning plate is adapted to the inner wall of the purification tank, and the cleaning plate is inclined and has a gasket on one side.

[0010] Preferably, the output shaft passes through one end of the purification tank and is fixedly connected to the upper end of the cylinder frame. The lower end of the sleeve has a connecting groove on its inner wall, and the inner wall of the connecting groove has three limiting grooves.

[0011] Preferably, the upper end of the rotating rod is adapted to and slidably connected to the inner wall of the connecting groove, and the limiting post is adapted to and slidably connected to the inner wall of the limiting groove.

[0012] Preferably, drive wheel one and drive wheel two are fixedly connected to the outer side walls of the output shaft and the screw, respectively, and drive belts are installed on the outer side walls of drive wheel one and drive wheel two.

[0013] Preferably, the purification tank has an inlet and an outlet at its upper and lower ends, respectively, and the outer walls of the inlet and outlet are equipped with switch valves.

[0014] A high-efficiency acid washing and purification process for quartz sand, used to implement the purification device described above, includes the following steps:

[0015] S1. Open the tank door, load the quartz sand to be purified into the filter cylinder, close the hinged cylinder cover on the outer wall of the filter cylinder, and then close the tank door to achieve a seal; inject acid solution through the inlet, the quartz sand comes into contact with the acid solution, and the acid solution reacts chemically with the impurities in the quartz sand to complete the acid washing and purification of the quartz sand.

[0016] S2. Start the motor to drive the output shaft to rotate, and the output shaft drives the stirring shaft and the filter cylinder to rotate synchronously. At the same time, drive wheel one drives drive wheel two to rotate through the drive belt. The screw rotates and drives the threaded sleeve to slide along the inner wall of the tank, thereby driving the filter cylinder to move upward and get away from the acid environment. The filter cylinder rotates during the upward process, and uses centrifugal force to throw the residual acid attached to the surface of the quartz sand through the side filter holes and bottom filter holes into the inner cavity of the purification tank.

[0017] S3. When the filter cylinder rotates, it drives the rotating rod to rotate, and the rotating rod drives the cleaning plate to rotate synchronously, pushing the waste acid and quartz sand residue attached to the bottom wall of the purification tank towards the liquid outlet, thereby improving the deacidification efficiency.

[0018] Compared with the prior art, the present invention provides a high-efficiency acid washing and purification device and process for quartz sand, which has the following beneficial effects:

[0019] When the output shaft is driven by the motor, it not only causes the filter cylinder to rotate synchronously, but also, through the cooperation of the drive wheel, drive belt, and screw, drives the filter cylinder to move upward and away from the acid environment, allowing the filter cylinder to maintain continuous rotation during the ascent. The centrifugal force generated by the rotation quickly ejects residual acid adhering to the surface of the quartz sand and within the gaps between the particles. The residual acid is discharged into the purification tank through the filter holes on the side and bottom walls of the filter cylinder, effectively reducing acid residue on the surface of the quartz sand.

[0020] The connecting groove and limiting groove on the inner wall of the sleeve drive the rotating rod to rotate synchronously. The rotating rod, in turn, drives three equally spaced connecting rods and a cleaning plate to rotate. The cleaning plate is inclined and its lower end fits into the inner wall of the purification tank, efficiently cleaning the waste acid and quartz sand residue adhering to the bottom wall of the purification tank and quickly pushing it towards the outlet, achieving simultaneous discharge of waste acid and residue. This shortens the acid discharge cycle and improves overall production efficiency. Attached Figure Description

[0029] Please see Figure 1 - Figure 6 This invention provides a technical solution for a high-efficiency acid washing and purification device for quartz sand, comprising: a purification tank 1, a tank door 2 hinged to the outer wall of the purification tank 1, a filter cylinder 3 disposed inside the purification tank 1, side filter holes 301 and bottom filter holes 302 respectively opened on the outer wall and bottom wall of the filter cylinder 3, a sleeve 303 fixedly connected to the middle of the filter cylinder 3, a cylinder frame 304 fixedly connected to the upper end of the filter cylinder 3, and a commonly used stirring mechanism in the market is provided in the inner cavity of the filter cylinder 3. The driving power of the stirring mechanism can be set to an external electric control drive, so there is no need to set a separate drive motor or other equipment in the filter cylinder 3. This is a common technology in the field of quartz sand acid washing. The required stirring mechanism can be used in this solution. In addition, a cylinder cover is hinged to the outer wall of the filter cylinder 3, which will not be described in detail or limited. A deacidification component 4 is provided at the upper end of the purification tank 1, and an acid discharge component 5 is provided on the inner wall of the purification tank 1.

[0030] The deacidification assembly 4 includes a bracket 401 fixedly connected to the upper end of the purification tank 1. A groove 402 is provided on one side of the bracket 401. A screw 403 is rotatably connected to the inner wall of the groove 402. A threaded sleeve 404 is threadedly connected to the outer wall of the screw 403, and the threaded sleeve 404 is slidably connected to the inner wall of the groove 402. A mounting plate 405 is fixedly connected to one side of the threaded sleeve 404. A stirring shaft 406 is rotatably connected to one end of the mounting plate 405 via a rotating shaft. A motor 407 is fixedly connected to the upper end of the bracket 401, and an output shaft 408 is fixedly connected to the output end of the motor 407. The deacidification assembly 4 enables the filter cylinder 3 to rise and rotate within the purification tank 1, efficiently deacidifying the acid-washed quartz sand, reducing acid residue on the surface of the quartz sand, reducing the difficulty of subsequent cleaning, and improving the purification quality.

[0031] The output shaft 408 is cross-shaped and is slidably connected to the inner wall of the stirring shaft 406. The inner wall of the stirring shaft 406 is provided with a groove that fits the output shaft 408. The cross-shaped output shaft 408 can drive the stirring shaft 406 to rotate synchronously; the groove facilitates the sliding of the stirring shaft 406 along the axial direction of the output shaft 408.

[0032] The acid removal assembly 5 includes a rotating rod 501 rotatably connected to the bottom wall of the purification tank 1. Three connecting rods 502 are fixedly connected to the outer wall of the rotating rod 501, spaced evenly. A cleaning plate 503 is fixedly connected to one side of each connecting rod 502. Three limiting posts 504 are fixedly connected to the upper outer wall of the rotating rod 501, arranged in a circular array. Rotation of the rotating rod 501 drives the connecting rods 502 and the cleaning plate 503 to rotate synchronously, effectively cleaning the waste acid and quartz sand residue adhering to the bottom wall of the purification tank 1, preventing residue accumulation from affecting subsequent acid washing and acid removal.

[0033] The lower end of the cleaning plate 503 is adapted to the inner wall of the purification tank 1. The cleaning plate 503 is inclined and has a gasket on one side. The cleaning plate 503 discharges the bottom residue and waste acid in the purification tank 1 through the outlet 102, thereby improving cleaning efficiency and shortening the acid discharge cycle.

[0034] The output shaft 408 passes through one end of the purification tank 1 and is fixedly connected to the upper end of the cylinder frame 304. The lower end of the sleeve 303 has a connecting groove 3031 on its inner wall, and the inner wall of the connecting groove 3031 has three limiting grooves 3032. The output shaft 408 drives the cylinder frame 304 and the filter cylinder 3 to rotate; the connecting groove 3031 facilitates cooperation with the rotating rod 501.

[0035] The upper end of the rotating rod 501 is fitted to and slidably connected to the inner wall of the connecting groove 3031, and the limiting post 504 is fitted to and slidably connected to the inner wall of the limiting groove 3032. The limiting post 504 can drive the rotating rod 501 to rotate when the sleeve 303 rotates, and the connecting groove 3031 can allow the sleeve 303 to slide along the axial direction of the rotating rod 501.

[0036] Drive wheel 6 and drive wheel 7 are fixedly connected to the outer walls of output shaft 408 and screw 403, respectively. Drive belt 8 is installed on the outer walls of drive wheel 6 and drive wheel 7. The rotation of output shaft 408 drives drive wheel 6 to rotate, and drive wheel 6 drives drive wheel 7 to rotate via drive belt 8, which in turn drives screw 403 to rotate.

[0037] The purification tank 1 has an inlet 101 and an outlet 102 at its upper and lower ends, respectively, and both the inlet 101 and the outlet 102 are equipped with switch valves on their outer walls. The inlet 101 facilitates the rapid addition of acid and cleaning solution; the outlet 102 allows the acid to be discharged from the inside of the purification tank 1.

[0038] A highly efficient acid washing and purification process for quartz sand includes the following steps:

[0039] S1. Open the tank door 2, load the quartz sand to be purified into the filter cylinder 3, close the cylinder cover hinged to the outer wall of the filter cylinder 3, and then close the tank door 2 to achieve a seal; inject acid solution through the liquid inlet 101, the quartz sand comes into contact with the acid solution, and the acid solution reacts chemically with the impurities in the quartz sand to complete the acid washing and purification of the quartz sand.

[0040] S2. Start motor 407 drives output shaft 408 to rotate, output shaft 408 drives stirring shaft 406 and filter cylinder 3 to rotate synchronously; at the same time, drive wheel 6 drives drive wheel 7 to rotate through drive belt 8, screw 403 rotates and drives threaded sleeve 404 to slide along the inner wall of tank 402, thereby driving filter cylinder 3 to move upward and get away from acid environment. Filter cylinder 3 rotates during the upward process, and centrifugal force is used to throw the residual acid attached to the surface of quartz sand through side filter hole 301 and bottom filter hole 302 into the inner cavity of purification tank 1;

[0041] S3. When the filter cylinder 3 rotates, it drives the rotating rod 501 to rotate. The rotating rod 501 drives the cleaning plate 503 to rotate synchronously, pushing the waste acid and quartz sand residue attached to the bottom wall of the purification tank 1 toward the liquid outlet 102, thereby improving the deacidification efficiency.

[0042] In practical use, this invention serves as a high-efficiency acid washing and purification device and process for quartz sand. First, open the tank door 2, open the cylinder cover hinged to the outer wall of the filter cylinder 3, load the quartz sand to be purified into the inner cavity of the filter cylinder 3, close the cylinder cover, and then close the tank door 2 to ensure that the purification tank 1 forms a sealed environment. Then, inject the acid solution required for acid washing into the purification tank 1 through the liquid inlet 101. The acid solution in the inner cavity of the purification tank 1 fully contacts and reacts with the quartz sand in the filter cylinder 3 to achieve the acid washing and purification process of the quartz sand.

[0043] After pickling, open the valve at outlet 102 and start motor 407 to drive the cross-shaped output shaft 408 to rotate. The rotation of output shaft 408 drives the stirring shaft 406 to rotate synchronously. In addition, the rotation of output shaft 408 drives drive wheel 6 to rotate synchronously. Drive wheel 6 drives drive wheel 7 on the outer wall of screw 403 to rotate synchronously via drive belt 8, thereby driving screw 403 to rotate inside tank 402. When screw 403 rotates, threaded sleeve 404 slides along the inner wall of tank 402. The moving mounting plate 405 and the stirring shaft 406 rise synchronously. Since the stirring shaft 406 is in conjunction with the filter cylinder 3 and the output shaft 408 drives the filter cylinder 3 to rotate continuously, the filter cylinder 3 maintains its rotation during the rising process, thus detaching from the acid environment inside the purification tank 1. At this time, under the action of centrifugal force, the acid remaining on the surface and in the gaps of the quartz sand inside the filter cylinder 3 is quickly thrown out and discharged into the inner cavity of the purification tank 1 through the side filter hole 301 and the bottom filter hole 302, thereby achieving the deacidification of the quartz sand.

[0044] As the filter cylinder 3 rotates and rises, the connecting groove 3031 opened on the inner wall of the lower end of the sleeve 303 moves along the axial direction of the rotating rod 501. When the filter cylinder 3 rotates, it drives the rotating rod 501 to rotate. The rotation of the rotating rod 501 drives the three connecting rods 502 and the cleaning plate 503 to rotate synchronously. The cleaning plate 503 cleans the waste acid and quartz sand residue attached to the inner wall of the purification tank 1. The cleaned residue is discharged together with the acid through the liquid outlet 102.

[0045] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description.
