A magnetic and non-magnetic pollutant filter

Abstract

The invention discloses a magnetic and nonmagnetic pollutant filter. The magnetic and nonmagnetic pollutant filter comprises a water inlet pipe, a filter body and a water outlet pipe, wherein a waterinlet valve is arranged on the water inlet pipe; internal threads are respectively arranged at the water inlet end and the water outlet end of the water inlet pipe; the water outlet end of the water inlet pipe is in threaded connection with the filter body; the filter body is provided with dual-layer filter cartridges by facing the water outlet end of the water inlet pipe; the second filter cartridge is arranged outside the first filter cartridge in a sleeving manner at a certain interval; the mesh diameter of the second filter cartridge is greater than that of the first filter cartridge; a magnetic rod group is arranged inside the water outlet pipe and is used for adsorbing magnetic pollutants. The filter in the application is convenient to disassemble and clean and good in filtering effect, and can realize filtering of the magnetic pollutants and nonmagnetic pollutants.

Description

technical field [0001] The invention relates to a pipeline filtering device, in particular to a magnetic and non-magnetic pollutant filter. Background technique [0002] Magnetic and non-magnetic pollutant filters are generally installed at the front end of the water pipe, or at the front end of the HVAC pipe where the return water enters the boiler. The magnetic filters that appear on the market now generally only filter magnetic impurities, and there has been no good way to filter non-magnetic impurities, because the HVAC pipeline is a closed cycle, heated by the boiler to the floor heating, and then returned to the boiler by the heat sink to continue heating A cyclic process will inevitably produce various pollutants after a long time. Obviously, it is not ideal for us to only filter magnetic impurities. Over the years, researchers have tried to make the mesh smaller, but the mesh will be blocked after a long time of use. However, it is troublesome to disassemble and cle...

The magnetic filters that appear on the market now generally only filter magnetic impurities, and there has been no good way to filter non-magnetic impurities, because the HVAC pipeline is a closed cycle, heated by the boiler to the floor heating, and then returned to the boiler by the heat sink to continue heating A cyclical process will inevitably produce various pollutants over a long period of time. Obviously, it is not ideal for us to only filter magnetic impurities. For many years, researchers have tried to make the mesh smaller, but the mesh will be blocked after a long time of use. However, it is troublesome to disassemble and clean the existing filter when cleaning.
