Description

Rainwater filtration processor

Technical Field

The invention relates to the technical field of water treatment, in particular to a rainwater filtering processor.

Background

The shortage of fresh water resources is a serious problem facing the world at present, and the fresh water resources are highly regarded by various countries. The rainwater is a good fresh water resource, the quality of the natural rainwater is good, and the rainwater falls to the ground surface to wash the ground surface in the rainfall process, so that the initial rainwater contains a large amount of pollutants, and the content of the pollutants in the rainwater runoff is gradually reduced and tends to be stable along with the continuation of rainfall. By utilizing the law, the rainwater discarding device is usually adopted in the conventional rainwater treatment system, so that rainwater with more initial pollutants is discarded, and middle and later stage rainwater is collected to be used as domestic water. The current rainwater discarding device is used for mechanically discarding rainwater on the principle that the initial rainwater flow is small, however, the common rainwater discarding device cannot filter pollutants in rainwater in the middle and later periods, and rainwater needs to be filtered again subsequently after discarding.

In the filtering process of the filter screen, impurities block the mesh openings, so that the flow in the flow guide pipe is reduced, the liquid level in the filter cylinder rises continuously, the piston is pushed to move upwards, the piston drives the extension rod and the slide rod to move upwards synchronously when moving, the sealing column is pulled out of the flow discarding pipe gradually, when the limiting ball enters the conical necking part of the water jacket (the water jacket is basically in a closed state or a state with small water yield), the sealing column is pulled out of the flow discarding pipe completely, the flow discarding pipe is in an open state, at the moment, water in the sedimentation cylinder flows back into the filter cylinder through the flow guide pipe and is discharged from the flow discarding pipe, so that the filter screen is washed reversely once, the impurities at the bottom of the filter cylinder are discharged together, along with the discharge of the water in the filter cylinder, the liquid level in the filter cylinder descends, the piston moves downwards, the sealing column is inserted into the flow discarding pipe again, the water jacket is sealed and is completely opened, and then the filter screen operates normally; after a period of time, when the filter screen is blocked again, the actions are automatically repeated, so that the filter screen is automatically cleaned.

Preferably, the inner wall of the filter cylinder is positioned below the piston, and a limit check ring is arranged below the piston. The limiting retainer ring is used for limiting the position of the piston.

Preferably, the upper side of the sedimentation cylinder is provided with a connecting support, the lower side of the connecting support is provided with a return pipe coaxial with the sedimentation cylinder, a ring cavity is formed between the return pipe and the inner wall of the sedimentation cylinder, the inner end of the water outlet pipe is communicated with the upper end of the return pipe, the outer wall of the return pipe is provided with an outer spiral belt, and the inner wall of the return pipe is provided with an inner spiral belt. After entering the annular cavity, the water flow enters the lower end of the return pipe along the outer spiral belt, rises along the return pipe and is discharged from the water outlet pipe; outer spiral area, interior spiral area constantly change the rivers direction to make the momentum of rivers reduce, rivers are gentler, thereby do benefit to the surface that outer spiral area, interior spiral area were deposited to the tiny particle silt of aquatic, silt gathers the back can remove the bottom of deposiing a section of thick bamboo along outer spiral area, interior spiral area, and the rainwater of discharging is more limpid from outlet pipe department at last.

Preferably, a sewage discharge pipe is arranged at the bottom of the sedimentation cylinder, a connecting rod is arranged at the center of the connecting support, the connecting rod is connected with the connecting support in a sliding mode, a sealing ball is arranged at the lower end of the connecting rod, a floating ball is arranged at the upper end of the connecting rod, and the ratio of the inner diameter of the flow guide pipe to the inner diameter of the water outlet pipe is 1.3-1.5. Because the flow of the flow guide pipe is larger than that of the water outlet pipe, the liquid level in the settling cavity can continuously rise along with the passage of time, when the liquid level reaches the position of the floating ball, the floating ball can float upwards, so that the sealing ball is pulled by the connecting rod to move upwards, the sewage discharge pipe is in an open state, water at the bottom of the settling cylinder and sediments are discharged from the sewage discharge pipe together, the liquid level in the settling cylinder descends after the water is discharged, and the sewage discharge pipe is closed; as the liquid level continues to rise along with the lapse of time, the sewage discharge pipe can be opened once at regular intervals for sewage discharge.
