The invention relates to a device which carries out the filtration on the fluid medium conveyed by the pipeline, in particular to a cleanable filter which can realize the hydrocyclone separation, surface interception and deep filtration of the impurity in the fluid medium at the same time. The filter is provided with an inlet pipeline, a filter unit group, a sewage drainage pipeline and an outlet pipeline; the filter unit group is internally provided with a standby filter unit; an inlet cutting valve is arranged between all filter units of the inlet pipeline and the filter unit group; the inlet pipeline is connected with each filter unit by the inlet cutting valve; an outlet cutting valve is arranged between all filter units of the outlet pipeline and the filter unit group; the output pipeline is connected with each filter unit by the outlet cutting valve. The device of the invention can carry out the maintenance under the situation that shutdown is not necessary and the pipeline normally conveys the medium, can replace the filter unit; furthermore, when the impurities are automatically back-cleaned, the pressure and flux of the conveyed medium can be ensured to be stable.

The invention discloses a filter cartridge dust collector with uniform air supply, which comprises a dust removal box body and an ash hopper, wherein the ash hopper is arranged below the dust removal box body and communicated; And the filter cartridge, the outer side wall of the upper end of the ash hopper is provided with an air duct and a static pressure box. Through the different settings of the vent area, the consistency of the air volume of each air outlet is ensured. After further equalization by the static pressure box, the air flow into the filter cartridge is uniform in size, ensuring the same dust removal load of each filter cartridge, and improving the filter cartridge. The dust removal efficiency also prolongs the service life of the filter cartridge. The airflow enters the annular pipe and the static pressure box through the air inlet, the contact area suddenly increases, the gas pressure becomes smaller, and the large particles in the air sink to the ash hopper under the action of gravity to prevent the filter cartridge from being blocked by large particles. Improve the dust removal effect.

The invention relates to a water treatment industry, and concretely relates to filtering of drinking water. The invention discloses relates to a double-outlet purified water machine switching water-production method having a discharged thick water recovery device. According to the invention, the booster pumps connected in series are arranged between a preposition filter bladder and a fine filter bladder; a thick water receiver with a backwater port is communicated with a discharged thick water outlet of the fine filter bladder, the backwater port is communicated with a booster pump inlet pipeline; the water outlet of the fine filter bladder is communicated with a pure water interface of a double-outlet faucet, and a water sensor is arranged on the water outlet of the fine filter bladder, the booster pump outlet pipeline is communicated with a purified water interface of the double-outlet faucet through a first purified water pipeline of the water sensor; a purified water valve or a pure water valve are opened for triggering the corresponding water sensor, an electric signal corresponding to purified water outlet or pure water outlet are output to an electric control apparatus for driving the booster pump for extracting the discharged thick water in the thick water receiver, or conveying is carried out with purified water in the preposition filter bladder, or successive conveying is respectively carried out with the purified water in the preposition filter bladder, and the discharged thick can be individually flowed out from the purified water interface or the pure water interface.
