Description

Technical Field

[0001] This utility model relates to the technical field of inositol wastewater treatment equipment, specifically to a phosphorus-containing wastewater treatment device for inositol production. Background Technology

[0002] Inositol is a naturally occurring cyclohexanehexol, belonging to the vitamin-like substances. It is widely found in plants (such as corn, beans, and nuts) and animal tissues, participating in various metabolic processes in organisms, such as regulating cell signaling, maintaining cell membrane stability, and promoting fat metabolism. Industrially, inositol is mostly extracted from raw materials such as corn soaking solution and is mainly used in medicine (such as for treating fatty liver and as an adjunct to diabetes medication), food additives (nutritional fortifiers), and cosmetics (moisturizing ingredients).

[0003] In related technologies, inositol production processes (such as acid hydrolysis extraction processes) generate wastewater containing high concentrations of phosphates (phosphorus mainly comes from phytic acid and its decomposition products in the raw materials). Quicklime (CaO, which reacts with water to form Ca(OH)2) is added to neutralize the acidity and remove phosphorus. When treating phosphorus-containing wastewater, quicklime is added to the wastewater tank, stirred to ensure thorough mixing, and finally filtered to remove total phosphorus from the filtrate.

[0004] However, quicklime (CaO) reacts with water to form Ca(OH)2, providing Ca²⁺. Ca²⁺ reacts with phosphate ions (PO4³⁻, HPO4²⁻, etc.) in wastewater to form calcium phosphate precipitates (such as Ca3(PO4)2), which have extremely low solubility and are fine solid particles. These precipitate particles not only suspend or settle to the bottom in the water, but are also adsorbed by water flow disturbance and minor roughness on the tank wall surface (such as scratches and oxide layers). Especially when the wastewater is left to stand, particles near the tank wall are more likely to adhere. If the particles attached to the tank wall are not cleaned in time, they will crystallize or solidify on the tank wall, forming residues that are more difficult to clean, thus affecting the quality of subsequent water treatment. To solve the above problems, a phosphorus-containing wastewater treatment device for inositol production is proposed. Utility Model Content

[0005] In view of this, the present invention provides a phosphorus-containing wastewater treatment device for inositol production. The present invention uses a stirring motor to drive the stirring shaft to rotate, which in turn causes the cleaning component to rotate. The stirring rod stirs the phosphorus-containing wastewater and quicklime, thereby making the quicklime fully mixed with the wastewater. Simultaneously, the first scraper and the second scraper scrape the inner wall of the wastewater tank, and the scraping component scrapes the residue at the bottom of the wastewater tank, thereby facilitating the cleaning of the residues adhering to the inner wall of the entire wastewater tank, making it difficult for the residues to adhere to the tank wall.

[0006] To solve the above-mentioned technical problems, this utility model provides a phosphorus-containing wastewater treatment device for inositol production, including a stirring motor installed at the bottom of a wastewater tank, a stirring shaft rotatably connected to the stirring motor inside the wastewater tank, a tank cover installed at the top of the wastewater tank, a liquid storage hopper connected to the bottom of the wastewater tank, multiple connecting blocks detachably installed on the surface of the stirring shaft, the connecting blocks being distributed along the axial direction of the stirring shaft, a cleaning component installed at the end of each connecting block away from the stirring shaft, a linkage plate installed between the sides of every two cleaning components away from the stirring shaft, a first scraper installed on the side of each linkage plate away from the stirring shaft, and a scraping component installed at the bottom of the stirring shaft.

[0007] Each cleaning component includes a stirring rod connected to a connecting block on the same plane. The stirring rod is used to stir the crushed quicklime combined with phosphorus-containing wastewater. A second scraper is provided at the end of the stirring rod away from the stirring shaft. The second scraper is used to scrape off the residue attached to the inner wall of the wastewater tank. The side of the connecting block that connects to the stirring shaft is arc-shaped.

[0008] A guide plate is provided on both the front and rear sides of the linkage plate. The guide plate is used to increase the shear force when the stirring rod stirs the sewage, so that quicklime and phosphorus-containing sewage can be further mixed. The guide plate is trapezoidal.

[0009] The surface of the stirring rod is provided with several water inlets, which are used to reduce the weight of the mixing tank and facilitate the mixing of sewage.

[0010] The scraping assembly includes a positioning ring fixed to the bottom of the stirring shaft. The positioning ring is used to install the linkage rod, thereby connecting the linkage rod to the stirring shaft. The linkage rod is fixedly installed on one side of the positioning ring. The linkage rod is used to connect the mounting frame to the positioning ring. The mounting frame is inclined on the linkage rod and is hollow and rectangular. The mounting frame is used to connect the linkage rod to the third scraper. The mounting frame is inclined along the curvature of the liquid storage hopper. The third scraper is installed on the side of the mounting frame facing the inner wall of the liquid storage hopper. The third scraper is used to scrape the residue on the inner wall of the liquid storage hopper. When the stirring shaft drives the positioning ring to rotate, the scraping assembly will rotate synchronously.

[0011] A feed pipe is connected to the tank lid, which connects the sewage tank to the crushing box. The feed end of the feed pipe is connected to the crushing box, which is used to install crushing rollers. A pair of crushing rollers are rotatably installed inside the crushing box. The two crushing rollers work together and grind the lumpy quicklime through the gap between them. The surface of the crushing rollers is provided with several crushing teeth. A feed hopper is installed at the top of the crushing box. The feed hopper is used to accurately drop the lumpy quicklime between the two crushing rollers for crushing. The feed hopper is hollow and inverted trapezoidal, and the discharge end of the feed hopper faces the middle between the two crushing rollers.

[0012] A plate valve is installed on the feeding pipe to control the opening and closing of the feeding pipe. A removable cover plate is installed on the top of the crushing box to facilitate the opening of the crushing box for adding quicklime.

[0013] In summary, compared with the prior art, this application includes at least one of the following beneficial technical effects: 1. The stirring motor drives the stirring shaft to rotate, which in turn causes the cleaning component to rotate. The stirring rod stirs the phosphorus-containing wastewater and quicklime, so that the quicklime is fully mixed with the wastewater. At the same time, the first and second scrapers scrape the inner wall of the wastewater tank, and the scraping component scrapes the residue at the bottom of the wastewater tank, thus facilitating the cleaning of the residues attached to the inner wall of the entire wastewater tank and making it difficult for the residues to adhere to the tank wall.

[0014] 2. The baffle plate is used to increase the shear force of the mixing rod when mixing sewage, so that quicklime and phosphorus-containing sewage can be further mixed. The water inlet is used to reduce the weight of the mixing tank and facilitate the mixing of sewage.

[0015] 3. The quicklime is further ground into powder by the grinding rollers in the grinding box and then added to the sewage tank, so that the phosphorus-containing sewage and quicklime can be fully mixed. Attached Figure Description
