The invention discloses a simple brine filter belonging to the field of brine freezing systems. The simple brine filter comprises a main
pipe, a valve and a side communication
pipe, wherein connecting flanges are welded on two sides of the main
pipe; a filter screen is arranged at the corresponding connecting
flange on the
tail side of the brine flow direction and is used for filtering particles in brine; the valve is arranged at the side communication pipe and is used for temporarily closing the side communication pipe; a connecting
flange is welded at the bottom of the side communication pipe and is connected with a cover plate; an adsorption
magnet is arranged inside the cover plate. During the installation of a freezing
system, the main pipe of the simple brine filter and a brine main pipe can be connected and installed in the freezing
system; after freezing is started, the particles in the brine which continuously circulates can be blocked by the filter screen and are deposited at the bottom of the side communication pipe,
metal particles in the brine are adsorbed to the adsorption
magnet in the side communication pipe, the valve which is arranged at the side communication pipe is closed, and the cover plate at the bottom of the side communication pipe is disassembled for cleaning. The simple brine filter is compact in structure, light in weight, smart, easy and convenient to install, and low in cost.
