Description

Technical Field

[0001] This utility model relates to the field of quartz sand production technology, specifically to an acid washing device for high-purity quartz sand. 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. In order to eliminate the adsorption on the surface of the diatomaceous earth carrier of the quartz sand raw material and reduce the delamination of chromatographic peaks, the carrier needs to be acid-washed before production and processing. Acid washing equipment is required for acid washing.

[0003] Existing pickling equipment uses stirring rods to agitate the internal quartz sand, improving the pickling efficiency. After pickling, acid residue remains inside the equipment, such as unreacted acid, quartz sand residue, and other impurities. Currently, manual cleaning of the inner wall of the equipment is often required to prevent the residue from affecting subsequent production. However, manual cleaning is tedious, consumes too much manpower, and increases the production cost of quartz sand pickling.

[0004] Therefore, in order to solve the above problems, this utility model provides an acid washing device for high-purity quartz sand. Utility Model Content

[0005] The purpose of this invention is to provide an acid washing device for high-purity quartz sand. The device has a simple structure and can effectively improve the acid washing efficiency of quartz sand.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an acid washing device for high-purity quartz sand, characterized by: a tank body with an inlet at the top and an outlet at the bottom; a stirring and heating mechanism inside the tank body, comprising a hollow rotating shaft and several stirring paddles evenly arranged on the hollow rotating shaft; the upper end of the hollow rotating shaft penetrating the center of the top wall of the tank body; a drive assembly on the outer top wall of the tank body, comprising a servo motor; the output end of the servo motor is connected to a gear one, which meshes with a gear two; the hollow rotating shaft is fixedly connected to the center of gear two. A cleaning mechanism is provided on the inner wall of the top of the tank body, comprising several high-pressure nozzles and a cleaning pipe; the cleaning pipe is arranged along the circumference of the top of the tank body, and the several high-pressure nozzles are evenly arranged on the cleaning pipe.

[0007] As a further embodiment of this invention: a support block is provided above gear one and gear two, and a servo motor is mounted on the support block. An electric heater is installed inside the hollow rotating shaft, and the power connector for the electric heater is connected to the top of the tank through the hollow rotating shaft. The power cord for the electric heater is connected to one side of the tank through a connecting pipe provided on the support block. Through the structural design of the drive assembly, not only can the hollow rotating shaft be driven to agitate the stirring paddle, but a connection channel can also be reserved for the power cord of the electric heater inside the hollow rotating shaft.

[0008] As a further embodiment of this invention: the input pipe of the cleaning pipeline passes through the top wall of the tank and connects to an external water supply. By setting up the cleaning mechanism, when the quartz sand acid washing is completed and the material is discharged, the residual quartz sand can be rinsed to accelerate the discharge, while the inner wall of the equipment can also be cleaned to prevent residues from affecting the next production run.

[0009] As a further aspect of this invention: the high-pressure nozzles and cleaning pipes are made of corrosion-resistant materials. The corrosion-resistant materials used for the high-pressure nozzles and cleaning pipes prevent corrosion during acid pickling, thus ensuring their usability. Simultaneously, the tank body, agitator, and hollow rotating shaft are also made of corrosion-resistant materials.

[0010] As a further embodiment of this invention: a support frame is provided at the bottom of the tank, and the lower bottom sidewalls of the tank converge towards the center, with the bottom of the converged area serving as a discharge port, and a valve is provided at the discharge port. The valve at the discharge port allows for convenient control of the discharge.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] By setting up a stirring and heating mechanism, during the pickling of quartz sand, not only can the solution be stirred to fully mix with the quartz sand and accelerate the pickling efficiency, but heat can also be transferred to the tank through a hollow rotating shaft via electric heating, thereby keeping the temperature inside the tank within a suitable range and ensuring pickling efficiency.

[0013] By incorporating a cleaning mechanism, the tank walls can be flushed to remove quartz sand residue after pickling. This cleaning mechanism allows for timely tank cleaning at the end of the discharge process, which is more efficient than manual washing, reduces labor costs, and lowers the overall cost of quartz sand pickling.

[0018] 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.

[0019] Please see Figures 1-3 As shown, this utility model provides the following technical solution:

[0020] A pickling device for high-purity quartz sand includes a tank 1 with an inlet 2 at the top and an outlet 3 at the bottom. A stirring and heating mechanism is installed inside the tank 1, comprising a hollow rotating shaft 4 and several stirring paddles 5 evenly distributed on the hollow rotating shaft 4. The upper end of the hollow rotating shaft 4 passes through the center of the top wall of the tank 1. A drive assembly is installed on the outer top wall of the tank 1, including a servo motor 6. The output end of the servo motor 6 is connected to a gear 8, which meshes with a gear 9. The hollow rotating shaft 4 is centrally fixedly connected to the gear 9. A cleaning mechanism is installed on the inner top wall of the tank 1, comprising several high-pressure nozzles 10 and a cleaning pipe 11. The cleaning pipe 11 is arranged along the circumference of the top of the tank 1, and the high-pressure nozzles 10 are evenly distributed on the cleaning pipe 11.

[0021] A support block 12 is provided above the first gear 8 and the second gear 9, and the servo motor 6 is mounted on the support block 12. An electric heater is installed inside the hollow rotating shaft 4. The power connector of the electric heater is connected to the top of the tank 1 through the hollow rotating shaft 4, and the power cord 7 of the electric heater is connected to one side of the tank 1 through a connecting pipe provided on the support block 12. Through the structural design of the drive assembly, not only can the hollow rotating shaft 4 be driven to drive the stirring paddle 5 for stirring, but a connection channel can also be reserved for the power cord 7 of the electric heater inside the hollow rotating shaft 4.

[0022] The input pipe 13 of the cleaning pipe 11 passes through the top wall of the tank 1 and connects to the external water supply. The cleaning mechanism allows for the rinsing of residual quartz sand during the acid washing process, accelerating discharge while simultaneously cleaning the inner wall of the equipment to prevent residues from affecting subsequent production.

[0023] The high-pressure nozzles 10 and cleaning pipes 11 are made of corrosion-resistant materials. These materials prevent corrosion during pickling, thus protecting them from damage. Similarly, the tank body 1, the agitator 5, and the hollow rotating shaft 4 are also made of corrosion-resistant materials.

[0024] A support frame 14 is provided at the bottom of the tank body 1. The lower bottom sidewall of the tank body 1 converges towards the center, and the bottom of the convergence point is set as the discharge port 3. A valve 15 is provided at the discharge port 3. The discharge can be easily controlled by the valve 15 at the discharge port 3.

[0025] During operation, the quartz sand to be pickled and the pickling solution are fed into tank 1 through inlet 2. The servo motor 6 is activated to drive gear 8 to rotate. Gear 8 meshes with gear 9, which in turn drives the hollow rotating shaft 4 and the agitator 5 to rotate and stir the quartz sand. Simultaneously, the electric heater is activated, transferring heat through the hollow rotating shaft 4 (made of a heat-conducting material) to the tank 1, thus maintaining the temperature within the tank 1 within a suitable range to ensure pickling efficiency. After pickling, residue will remain on tank 1. The high-pressure nozzle 10 of the cleaning mechanism is activated to rinse the tank and collect the quartz sand residue. After discharge, the valve 15 of outlet 3 is closed, the high-pressure cleaning nozzle 10 is activated to rinse the inner wall, and the servo motor 6 is activated to drive the agitator 5 to rotate, thus cleaning the inner wall of tank 1 and the agitator 5. After washing, the valve 15 of outlet 3 is opened to discharge and collect the cleaning water.

[0026] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
