Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of screening devices, in particular to a raw material screening device for defoaming agent processing with a recovery mechanism. Background Art
[0002] A screening device is a device that screens and subdivides items. During production and processing, the screening device is used to screen out raw materials that meet the use conditions. The processing of defoaming agents requires that the raw materials be screened before use. Screening through a screening device is an important link to ensure the quality of the processed defoaming agents.
[0003] In the related art, when screening the defoaming agent raw materials, the raw materials that do not meet the use conditions are recycled, and the recycled raw materials are mixed with raw materials that meet the use conditions for repeated screening to ensure that the raw materials that meet the use conditions are fully screened out to avoid waste of raw materials.
[0004] When repeated screening is performed, the screened defoamer is sucked into the box by a suction fan for repeated screening. If the airflow speed of the suction fan is too fast, the particles may be unevenly dispersed in the airflow and difficult to be stably captured; if the airflow speed is too slow, it may not provide enough power to bring the particles into the suction fan. When the particle size is too small, the particles may be difficult to be stably captured due to airflow disturbance, resulting in a decrease in recovery efficiency. Therefore, we need to propose a raw material screening device for defoamer processing with a recovery mechanism. Utility Model Content
