Description

Technical Field

[0001] This utility model relates to the field of pretreatment technology for chemical raw materials, and in particular to a pretreatment device for chemical raw materials. Background Technology

[0002] Chemical raw material pretreatment equipment is a combination of equipment used in the chemical production process to perform preliminary processing on raw materials, with the aim of making the raw materials meet the requirements of subsequent core reactions or processing steps.

[0003] To this end, patent No. 202122819121.7 discloses a pretreatment device for chemical raw materials, including an alkaline wastewater discharge component, which includes an alkaline wastewater discharge pipe, and an alkaline wastewater control valve installed on the outer surface of the alkaline wastewater discharge pipe; one end of the alkaline wastewater control valve is fixedly connected to a reaction vessel component, which includes a reaction vessel, and the reaction vessel has a reaction chamber inside; this pretreatment device for chemical raw materials can detect the acidity and alkalinity inside the reaction chamber through a pH meter, so that it can be more accurately neutralized to meet the discharge standards; the hot water component can increase the internal reaction conditions to meet the needs; the addition of flocculant can make it settle quickly and perform solid-liquid separation; and the addition of a stirring component can increase the stirring speed and reaction rate, thus solving the problem of incomplete alkaline wastewater reaction and environmental damage caused by the past.

[0004] The existing technical solutions mentioned above have the following drawbacks: Although the pH meter can detect the acidity and alkalinity inside the reaction chamber, enabling more precise neutralization and meeting emission standards, the traditional stirring structure has a single stirring direction and insufficient stirring intensity when mixing chemical raw materials and neutralizing liquid. This can easily lead to dead zones in the material flow within the container, making it impossible to achieve thorough mixing. Furthermore, when processing solid-liquid mixtures containing solid particles, some stirring devices cannot effectively prevent particle sedimentation, resulting in the mixing uniformity failing to meet standards.
