The invention relates to the technical field of sewage filtration, in particular to an anti-freeze type filter. The anti-freeze type filter comprises two cylinder bodies which are connected through a communicating pipe; the communicating pipe is arranged in the middle of the outer wall of each cylinder body and used for balancing the water pressure between the two cylinder bodies; each cylinder body is internally provided with a sewage cavity, a pure water cavity and a transition cavity, wherein the sewage cavity and the pure water cavity are separated from the transition cavity through a filter layer; the sewage cavity is positioned in the pure water cavity; a water outlet of the sewage cavity is positioned in the filter layer; a water inlet of the pure water cavity is positioned in the filter layer; the transition cavity is arranged on the lower part of the cylinder body; a water feeding device is arranged outside the cylinder body and provided with a main pipe; both sides of the main pipe are connected with a water outlet pipe; a water inlet pipe is connected to the water outlet pipe; a control valve is arranged on a pipeline positioned between the main pipe and the water inlet pipe; a control valve is arranged on the water inlet pipe; and the water outlet pipe of the water feeding device is connected with the sewage cavity inside the cylinder body.
Description
technical field [0001] The invention relates to the technical field of sewage filtration, in particular to an antifreeze filter. Background technique [0002] Filter tanks play a very important role in urban water supply treatment, industrial water supply treatment, industrial circulating water treatment, sewage treatment and other fields. At present, the most commonly used filter tanks are mostly composed of tank body, filter material filter layer, filter material support device and water distribution device for backwashing filter material. The filter material is generally made of quartz sand, anthracite or fiber filter material. Material, as the patent No. is ZL200510049755.1 (publication number is CN1712096A) Chinese invention patent "a kind of fiber filter pond" just discloses a kind of filter pond that adopts fiber filter material, and it comprises filter chamber, filter chamber top inlet The backwashing water distribution device on the side of the water tank and the f...
