Description

Technical Field

[0001] This utility model relates to the technical field, and in particular to a negative pressure distillation detergent concentration device. Background Technology

[0002] Negative pressure distillation detergent concentration equipment is a specialized device for detergent production. It combines negative pressure distillation and concentration technologies. This device can perform distillation at lower temperatures and pressures, thereby effectively extracting and concentrating the active ingredients in detergent while avoiding damage to the materials caused by high temperatures. For example, a Chinese patent discloses a detergent concentration tank with application number CN201820206870.8. It utilizes the weight difference caused by density differences to eliminate non-detergent liquid impurities, ensuring the purity of the detergent product. However, its effect on removing soluble impurities is not significant, resulting in some impurities remaining inside the detergent that cannot be removed. This has certain limitations and affects the quality of the detergent. Utility Model Content

Impurities separated by the separator are stored for further processing.

[0011] According to the negative pressure distillation detergent concentration device of this utility model, the motor is provided with a protective shell, and the lower surface of the protective shell is fixedly connected to a right-angle plate. The protective shell protects the motor and prevents the external environment from affecting the motor.

[0012] Beneficial effects: Compared with the existing technology, this new negative pressure distillation detergent concentration device uses heat transfer oil to make the inside of the tank uniformly heated, and then reduces the pressure after injecting inert gas through the gas box. This can maintain the pressure stability inside the distillation tank while lowering the boiling point of the volatile components in the detergent, allowing the substances to evaporate at a lower temperature. Finally, the substances are separated from impurities by a separator and then enter the tank through a reflux pipe. Attached Figure Description
