Description

Technical Field

[0001] This utility model relates to the field of chemical material processing technology, specifically a pulping device for preparing silica. Background Technology

[0002] A slurry preparation device for silica is a specialized piece of equipment used in the silica production process to disperse and mix raw materials into a uniform slurry. Its core function is to use mechanical stirring and shearing to fully mix silica particles with solvent, forming a slurry with uniform particle size and good flowability, thus laying the foundation for subsequent processes (such as precipitation and drying).

[0003] Chinese utility model patent CN118594339A discloses a carbon black slurry pulping equipment and method, specifically relating to a silica pulping tank and method with a full-state pulping and automatic sampling device. The tank includes a vessel with a stirrer installed in the center of its inner cavity. Several ultrasonic transducers are installed at intervals from top to bottom on one side wall of the tank, electrically connected in parallel and connected to an ultrasonic generator installed beside the tank. An automatic sampling device extending into the bottom of the tank is vertically installed on the other side wall of the tank for sampling from the upper, middle, and lower layers. This pulping tank helps to increase the full-state oscillation and deagglomeration of the micro-agglomerates in the silica slurry at the molecular level, and can extract samples in all states for analytical testing.

[0004] Existing technologies typically require shutdown before sampling and analysis can be performed, making dynamic sampling and testing during the pulping process impossible. This leads to delays in detecting pulp parameters, affecting real-time monitoring and quality control of the pulping process. Furthermore, cross-contamination between different batches of pulp can easily occur, failing to effectively guarantee pulp purity and reducing product quality and market competitiveness. Therefore, a pulping device for precipitated silica preparation is needed to solve these problems. Utility Model Content

[0024] Specifically, the left side of the pulper body 2 near the bottom is fixedly connected to one end of the feed pipe 401, the end of the feed pipe 401 away from the pulper body 2 is fixedly connected to the top feed end of the test bottle 412, the bottom of the test bottle 412 is fixedly connected to one end of the discharge pipe 405, control valves are provided on the discharge pipe 405 and the feed pipe 401, and a liquid level sensor and a water pressure sensor are provided inside the test bottle 412.

[0025] Specifically, the top front end of the support frame 407 is fixedly connected to the bottom of the cleaning pump 408 near the right side, the water inlet end of the cleaning pump 408 is fixedly connected to one end of the water inlet pipe 411, and the water outlet end of the cleaning pump 408 is fixedly connected to one end of the water outlet pipe 410.

[0026] Specifically, the top left side of the support frame 407 near the rear end is fixedly connected to the bottom of the mounting frame 404, the top of the mounting frame 404 is fixedly connected to the bottom of the detection device 403, and the front of the detection device 403 is fixedly connected to the outer surface of the test bottle 412.

[0028] Specifically, the right side of the support frame 407 is fixedly connected to the left side of the fixed frame 1 near the bottom.

[0029] In operation, the silica raw material to be pulped is fed into the pulper body 2 through the feeding end. Then, the drive motor 3 is started, and its output drives the stirring shaft 9 to rotate. The rotation of the stirring shaft 9 causes the stirring blades, the oscillating frame 6, and the scraper 7 to operate synchronously. The stirring blades agitate the raw material at a specific angle and speed, initially dispersing the agglomerated silica particles through shearing and grinding, while simultaneously pushing the material to diffuse around the pulper cavity. During rotation, the oscillating frame 6 oscillates periodically along the slide rail 8, and its flexible swing arm continuously taps the raw material accumulated on the sidewalls of the cavity, preventing material adhesion and ensuring uniform dispersion. The scraper 7, fixed to the oscillating frame 6, adheres closely to the bottom of the cavity, scraping away the attached raw material layer with constant pressure, avoiding dead zones and forming a three-dimensional circulating pulping flow field in conjunction with the stirring blades. Through the synergistic action of these components, the silica raw material gradually mixes thoroughly with the solvent. After repeated shearing, kneading, and dispersion, a slurry with uniform particle size and good flowability is finally formed, laying the foundation for subsequent processing. During the stirring process, it is difficult for operators to monitor the slurrying status of the silica raw material. If timely monitoring is needed, the control valve on the feed pipe 401 can be opened. Once the control valve on the feed pipe 401 is opened, the slurry inside the main body 2 of the pulper flows into the test bottle 412 through the feed pipe 401. After the liquid level sensor in the test bottle 412 detects sufficient slurry, it electrically closes the control valve on the feed pipe 401, thus preventing more slurry from flowing out. Subsequently, the test bottle 412 is monitored by the detection device 403. The slurry in the sample is tested, and the results are displayed by the controller 402. After testing, the cleaning pump 408 is driven to pump water from the water tank 406 into the inlet pipe 411, and then into the test bottle 412 through the outlet pipe 410. The water is then guided back into the sampling pipe 401 near the front end. After the front end of the sampling pipe 401 and the test bottle 412 are filled with water, the water pressure sensor in the test bottle 412 senses a certain water pressure and electrically opens the control valve on the discharge pipe 405. At this time, high-pressure water flows back from the front end of the sampling pipe 401 and the inside of the test bottle to flush away the residual slurry, which then exits through the discharge pipe 405, avoiding cross-contamination between different batches of slurry and preparing for the next sampling and testing.

[0030] In summary, this slurry preparation device for silica production utilizes a full-state sampling device 4 to dynamically sample and detect slurry during the slurry process, avoiding downtime and delayed analysis and ensuring controllable slurry parameters. The entire process of sampling, testing, and cleaning is automated, reducing manual intervention and shortening the production cycle. A closed-loop high-pressure cleaning system prevents cross-contamination between different batches of slurry, ensuring purity. Sensors monitor anomalies in real time, automatically alarming and interrupting the process to reduce the risk of equipment damage. Detection data is automatically stored, supporting process review and standardized production management.
