Automatic continuous quick filtering system

Abstract

The invention discloses an automatic continuous quick filtering system and relates to the field of filtering equipment. The automatic continuous quick filtering system comprises a plurality of same filtering tanks and a control device, wherein each filtering tank comprise a tank body; a water distributor, a filtering filler layer and a water collector are sequentially arranged in each tank body from top to bottom; a three-way valve is arranged at the top of each tank body; each three-way valve comprises a water inlet, a first water outlet and a second water outlet; the first water outlet of each three-way valve is connected with a water inlet of each water distributor; the outlet end of each water collector outward extends out of the corresponding filtering tank; the water inlets of the three-way valves are connected by a water inlet manifold to form a whole; the second water outlets of the three-way valves are connected by a backwash water outlet manifold to form a whole; the outlet ends of the water collectors are connected by a water outlet manifold to form a whole. According to the automatic continuous quick filtering system disclosed by the invention, a backwash process and a filtering process are simultaneously performed, and the system usually supplies water; by adopting unique water distributors and water collectors, water flow becomes laminar flow in the whole filtering process, and the quality of effluent is stable.

Description

technical field [0001] The invention relates to the field of filtering equipment, in particular to an automatic continuous rapid filtering system. Background technique [0002] In the process of working water, surface water, agricultural irrigation, aquaculture and circulating water, it is necessary to remove suspended matter in the water through a filter. [0003] The traditional filter uses main pipes and branch pipes to distribute water through water distribution holes or wedge-shaped filter pipes. The filter layer is supported on the filter plate, and the filter plate is equipped with a filter head. After collecting water through the filter head, it is discharged from the tank through the outlet pipe. body. Considering that the transportation generally uses multiple filters in parallel for large water volumes, and generally uses one filter for small water volumes [0004] The filter uses granular filter material as the medium. When the raw water passes through the filt...

Problems solved by technology

[0004] The filter uses granular filter material as the medium. When the raw water passes through the filter layer, the suspended matter is intercepted by the filter layer, and the clean water passes through the filter layer to purify the raw water. After filtering for a period of time, the suspended matter intercepted on the surface of the filter layer increases, resulting in an increase in blocking force. , the filter layer needs to be backwashed. Generally, the filtered water is used as the backwashing water source for the backwashing of the filter. It needs to be equipped with a backwashing water tank and a backwashing water pump. Filtering, backwashing water inlet valve, backwashing water outlet valve, the filtering and backwashing of the filter are realized through the programming of the PLC automatic control system, the defect of this filter is mainly the same as the need to stop the water inlet during backwashing, and continuous filtration is not realized
