Description

TECHNICAL FIELD

[0001] The utility model belongs to the field of liquid separation and filtration, especially relates to a liquid separation and impurity filtering equipment. BACKGROUND

[0002] Liquid separation and impurity filtration is a process that removes impurities from liquid by physical or chemical methods to obtain clean liquid. It is an important process to remove impurities in liquid, which is widely used in daily life, industrial production and scientific experiments. The appropriate filtering method and equipment should be selected according to the properties of the liquid and the types of impurities, and the standard operation steps should be followed to obtain the best filtering effect.

[0003] The Chinese patent with publication number CN112023522A discloses a solid-liquid separation equipment for animal and plant extract cosmetics, which comprises a triangular separation frame and a separation cylinder. A separation mechanism is fixedly installed in the separation cylinder. An inclined surface is opened on the triangular separation frame, and a toothed plate is fixedly installed on the inclined surface. An impurity separation tank is rotatably installed on one side of the outer wall of the triangular separation frame. An inclined surface is opened at the bottom end of the impurity separation tank. A rectangular groove is opened at the bottom end of the outer wall of one side of the impurity separation tank. A first filter screen is fixedly installed in the rectangular groove. The first filter screen is a honeycomb hole filter screen. The metal screen on the filter frame can filter the solid impurities in the mixed liquid. The filter frame can be replaced according to the actual situation, which is convenient for users to make reasonable selection. Then, the mixed liquid is filtered again by the first filter screen on the impurity separation tank. The multi-level filtration makes the solid impurities in the mixed liquid less and less.

[0004] However, the impurities in the above-mentioned patent are easy to deposit on the filter screen, causing blockage, and the filter screen needs to be cleaned frequently, which is time-consuming and labor-intensive. Therefore, a new device needs to be designed. UTILITY MODEL CONTENTS
