Self-cleaning geothermal heating filtering device

Abstract

The invention discloses a self-cleaning geothermal heating filtering device. The self-cleaning geothermal heating filtering device comprises a device shell, a filtering mechanism and a cleaning mechanism, wherein the filtering mechanism and the cleaning mechanism are installed in the device shell. The device is provided with a cover body with a columnar cavity, a water inlet pipe tangentially communicated with the columnar cavity of the cover body, a communicating hole, a water outlet pipe communicated with a filter cartridge and a precipitation cavity, so that water flow forms rotational flowoutside the filter cartridge to scour the surface of the filter cartridge while filtering, impurities are prevented from gathering on the surface of the filter cartridge; the service life of the filter cartridge is prolonged while the filtering effect is ensured; by arranging a scraper, an impeller plate, a rotary drum and a connecting rod, kinetic energy of water is used for driving the impellerplate to rotate, the impeller plate drives the scraper to rotate, scaling on the surface of the filter cartridge is scraped off through the scraper, the filtering effect is improved, and the self-cleaning effect is improved; meanwhile, the impeller plate mounted at the lower end of the scraper is utilized to increase the flow velocity of rotational flow and accelerate precipitation aggregation and precipitation.

Description

technical field [0001] The invention relates to the field of geothermal heating equipment, in particular to a self-cleaning geothermal heating filter device. Background technique [0002] Since the circulating water in the geothermal heating device circulates for a long time, it is easy to produce scale or impurity particles in the circulating water itself, which will easily affect the life of the geothermal heating equipment and pipelines, and even cause equipment damage, so a filter device is needed. [0003] The traditional filter device adopts a single fixed filter device, and the surface of the filter device is prone to scaling and accumulation of impurities, resulting in a short service life of the filter device and a decrease in the filtering effect, which cannot guarantee the filtering effect. Contents of the invention [0004] Based on the deficiencies in the prior art mentioned in the background art above, the present invention provides a self-cleaning filter dev...
