Multifunctional reaction kettle with passive automatic anti-overflow function

Abstract

The invention discloses a multifunctional reaction kettle with a passive automatic anti-overflow function. The reaction kettle comprises a kettle body and a kettle body upper cover mounted at the upper end of the kettle body, wherein a stirring rod sleeve is mounted in the center of the kettle body upper cover, a stirring rod is arranged in the stirring rod sleeve in a penetrating manner, a stirring and crushing knife is fixedly mounted at the bottom of the stirring rod, the top of the stirring rod is in driving connection with the output end of a speed regulating motor, a feeding opening is formed in the kettle body upper cover, a discharging opening with a discharging valve is formed in the bottom of the kettle body; an adjusting handle is rotatably mounted at the upper end of the stirring rod, and a pair of auxiliary blades capable of rotating around a horizontal axis is rotatably mounted at the lower end of the stirring rod. The multifunctional reaction kettle disclosed by the invention can overcome the problem of low drying and dissolving efficiency of existing drying equipment and dissolving equipment on viscous solid and high-viscosity liquid, has an automatic anti-overflowfunction, is simple and passive, is beneficial to reduce the transfer loss of products and the consumption of manpower, and can improve the production and experiment efficiency.

Description

technical field [0001] The invention relates to the technical field of reactor equipment, in particular to a multifunctional reactor with passive automatic overflow prevention function. Background technique [0002] The drying and dissolving of substances is an important process in natural science laboratory preparation and chemical production. For drying, vacuum drying is better in the prior art, and mature equipment is a vacuum drying oven or a rotary vacuum dryer. However, the vacuum drying box only has two functions of decompression and temperature rise. The vacuum dryer adds the function of slow rotation to speed up the drying speed of the substance. Good, but for the solvent removal of viscous solids, there is a problem that it cannot be pulverized, and it can only dry the surface but not the inside. For the solvent removal of high-viscosity liquids, due to the high viscosity of the liquid, in addition to the difficulty of removing the solvent inside the liquid, ther...

Problems solved by technology

However, whether it is an axial flow type or a radial flow type stirring impeller, it can only apply axial thrust or shear force to the liquid to form a turbulent or laminar flow, but it cannot crush the solids in it, so it is only suitable for powder non-viscous Viscous solids and ordinary low-viscosity liquids have good dissolution efficiency, but for solids with self-adhesiveness in solvents and high-viscosity liquids, especially some highly viscous liquids, the swelling is very slow at low temperature, but it will turn to Insoluble amphiphilic polymers, the dissolution efficiency is very low

[0004] Regardless of laboratory preparation or chemical production, the product that dissolves or entrains a certain solvent is first removed from the solvent (drying), and then dissolved in another solvent (dissolution), such as the product removes the organic phase solvent and then dissolves in the water phase solvent. , is a very common operation process, but in the prior art, drying and dissolving requires two different equipments, and there is a product transfer step. In this process, for high-viscosity products, the amount of loss cannot be ignored

Simultaneously, the drying and dissolving efficiency for this product is very low, and this is the main shortcoming that the prior art exists
