Anhydrous lanolin production leaching liquid filtering device

Abstract

This utility model discloses a filtration device for the extract of anhydrous lanolin production, belonging to the technical field of filtration devices for anhydrous lanolin production. It includes: a vertical leaf filter; and an annular manifold surrounding the vertical leaf filter, connected to the inlet pipe of the vertical leaf filter, with a liquid pump installed on the inlet pipe. The utility model connects to the supply pipe for scouring wastewater via a pipe joint. The scouring wastewater enters a settling tank through a first pipe and settles, where deposited impurities are located below the coarse filtration channel. The second pipe is alternately opened, allowing scouring wastewater with remaining floating impurities to enter the coarse filtration channel for coarse filtration before entering the annular manifold for further filtration. Natural sedimentation and level difference are used to achieve settling and pre-filtration of the scouring wastewater. Under the suction of the liquid pump, the scouring wastewater in the annular manifold enters the vertical leaf filter through the inlet pipe for fine filtration, resulting in good filtration effect and high filtration efficiency.

Description

Technical Field

[0001] This utility model belongs to the technical field of filtration devices for anhydrous lanolin production, and particularly relates to a filtration device for extracts in anhydrous lanolin production. Background Technology

[0002] Lanolin is a secreted oil that adheres to wool. It is a pale yellow or brownish-yellow ointment that is sticky and slippery, with a faint but distinctive odor. Extract filtration is an important operation in solid-liquid separation. Its purpose is to remove solid impurities from the extract and obtain a clear liquid, providing qualified raw materials for subsequent purification, concentration, and analysis steps. In the production of anhydrous lanolin, the extract filtration step is the key step in removing solid impurities (such as wool fiber fragments, mud, insoluble inorganic salts, etc.) from the solution after extraction.

[0003] Chinese Patent (CN202221517164.8) discloses a filtration structure for extracting lanolin in the production of anhydrous lanolin, relating to the field of lanolin production technology. The structure includes a working cylinder with a first sealing groove on its upper surface. A top plate is fitted onto the working cylinder, and a fitting ring is fixedly connected to the lower surface of the top plate. A first gasket is fitted onto the inner surface of the working cylinder near its center. A fixing frame is fixedly connected to the inner surface of the working cylinder by multiple fastening bolts. A filter membrane is fixedly connected to the inner surface of the fixing frame, and a second gasket is fitted onto the lower surface of the working cylinder.

[0004] Currently, the filtration of anhydrous lanolin includes static sedimentation, coarse pre-filtration, and precision filtration. Existing single-unit filtration methods cannot meet the requirements of industrial-scale extraction liquid filtration, resulting in poor filtration effect and low filtration efficiency.

The upper ends of the multiple settling tanks are connected to a pipe joint through a first pipe. A coarse filtration channel is provided on the side of each settling tank, and a filter screen is provided in the coarse filtration channel. The coarse filtration channel is connected to the ring manifold through a second pipe. A third pipe is provided on the side of each settling tank, which is located below the coarse filtration channel and is connected to the waste liquid pipe of the vertical leaf filter.
