Filtering device

Abstract

The invention relates to a filtering device. The filtering device comprises a shell, wherein the shell is divided into an inner cavity and an outer cavity; the inner cavity is connected with a residue outlet which is formed at the bottom of the inner cavity; the outer cavity is connected with liquid outlets which are formed on two sides of the bottom of the outer cavity; a filter screen is arranged on a wall of the inner cavity; a residue outlet pipeline is arranged at the periphery of the residue outlet, and is fixedly connected with the bottom of the outer cavity; a dredging air injection device is arranged at a position, which is aligned with the residue outlet, in the residue outlet pipeline, and comprises an injection orifice, an air inlet pipe and an air source; the injection orifice is formed in the residue outlet pipeline; and the air inlet pipe is arranged outside the residue outlet pipeline. The invention has the advantages that the device comprises the dredging air injection device of which an outlet is aligned with the residue outlet, and the dredging air injection device regularly performs air injection to raise medicine residue which is deposited at the residue outlet, so that the residue outlet is kept smooth; and the inner cavity and the outer cavity are formed in the shell, the outer cavity is connected with the liquid outlets, the inner cavity is connected with the residue outlet, and residue and liquid are separated, so that the device has a good filtering effect.

Description

Technical field [0001] The invention relates to a filtering device. Background technique [0002] At present, the filtering devices appearing on the market include a container. The container is equipped with a filter screen. The container also has a slag outlet and a liquid outlet. The slag outlet of this filter device is easy to be blocked by the deposited slag, and the container is generally There is no distinction between an inner cavity and an outer cavity, and the effect of filtering and removing slag in one cavity is not very satisfactory. Therefore, it is necessary to provide a new technical solution to solve the above-mentioned problems. Summary of the invention [0003] The invention provides a filtering device with good filtering effect and smooth dredging. [0004] The technical solution to be solved by the present invention is: [0005] A filtering device includes a housing, the housing is divided into an inner cavity and an outer cavity, the inner cavity is connected w...
