Filter device

Abstract

The invention belongs to the technical field of filtering devices, and particularly relates to a filtering device which comprises a drainage mechanism, a filtering mechanism and a collecting mechanism. The drainage mechanism is detachably mounted above the filtering mechanism, and the filtering mechanism is detachably mounted above the collecting mechanism; the drainage mechanism is used for draining to-be-filtered liquid; filter paper is placed in the filtering mechanism; the filtering mechanism is used for supporting the filter paper and outputting filtrate; and the collecting mechanism is used for collecting the filtrate. The filtering device has the advantages of being simple to operate, reasonable in design, convenient to clean and high in filtering speed, and after the device is used, the drainage mechanism, the filtering mechanism and the collecting mechanism can be detached to be cleaned separately. The device can be used for filtering under the condition that a glass rod is not used, the detachable structural design is adopted, the device can be detached during storing and taking, the occupied space is small, and the device further has the advantage of being convenient tostore and take.

Description

technical field [0001] The invention belongs to the technical field of filtering devices, and in particular relates to a filtering device. Background technique [0002] The filtration operation is completed through a filter device. When filtering, filter paper needs to be installed in the filter device. Filtration is the penetration of liquid (or gas) in suspension (or heating gas containing solid particles) under the action of gravity, driving force or other external forces. Filter paper, solid particles and other substances are retained by the filter paper, thereby separating solids and other substances from liquid (or gas). At present, the commonly used filter device in the laboratory is a common funnel. Before filtering, the filter paper needs to be folded in half twice in a row to form a 90° central angle shape. Then put the folded filter paper into three layers on one side and one layer on the other side to form a funnel shape. Place the funnel-shaped filter paper i...

AI Technical Summary

Problems solved by technology

In the process of filtering with an ordinary funnel, both hands are occupied when adding materials, one hand holds the container containing the liquid to be filtered, and the other hand holds the glass rod for drainage, which is extremely inconvenient

Moreover, this device has problems such as slow filtration speed, long pouring time of the liquid to be filtered, and delays in work and time.
