Multi-filter cylinder automatic backwashing filter apparatus

Abstract

The invention discloses a multi-filter cylinder automatic backwashing filter apparatus. A housing is divided into an upper chamber and a lower chamber by a separation plate. The separation plate is provided with filter cylinders in the manner of one, two, or multiple concentric circles. The sidewall of the housing under the separation plate is provided with a sewage inlet, and the sidewall of the housing above the separation plate is provided with a pure water outlet. A motor of a backwashing mechanism drives a main shaft to rotate. A lifting mechanism drives the main shaft to go up and down. A multi-way connection seat connects the main shaft, rotating arms and a waste pipe together. The main shaft drives the rotating arms to lift and rotate. The waste pipe is fixed. Suction nozzles fixed on the upper end port of the rotating arms can be in sealed connection with water inlets on the separation plate. The end part of the waste pipe is connected with an electric drain valve or a pneumatic drain valve. A control system controls the actions of the motor, the lifting mechanism and the electric drain valve or the pneumatic drain valve. The filter apparatus has the advantages of small size, large amount of water filtration, high production efficiency, good filtration effect of filtered water, good backwashing effect, low frequency of backwashing, long-life apparatus, low maintenance rate, and saving backwash water.

Description

technical field [0001] The invention relates to a filter device. Background technique [0002] In the fields of metallurgy, electric power, petroleum, chemical industry, medicine, food, printing and dyeing, papermaking, urban water supply, central air conditioning, river water purification, reclaimed water treatment, agricultural irrigation, sewage treatment, etc. In the filtration and separation process of water, emulsion and other fluids in the system, many enterprises still use traditional filters. [0003] The filter cartridge structure of traditional filter equipment mostly adopts a single filter cartridge filter structure or a multi-filter filter structure in which multiple different filter elements are superimposed. Multi-filter filter equipment filters layer by layer, and the filter effect is good, but the amount of filtered water is small, the water output of the filter equipment is small, and it is not easy to clean up after the filter fails. The filter element i...

AI Technical Summary

Problems solved by technology

The filter still has the following disadvantages during operation: (1) the effect of backwashing is poor, and when the clogging is serious, the filter cartridge needs to be manually disassembled for cleaning, which consumes manpower and material resources; (2) the effective filtration area is still small, and the amount of filtered water is small. Low efficiency; (3) It is necessary to stop filtering to carry out backwashing, the amount of filtered water is small, and the production efficiency is low; (3) In the process of recycling water, it is inevitable to be contaminated with dirt, bacteria, etc., and hardness ions such as calcium and magnesium in the water will also Continuous concentration, these factors will lead to shortened filter life and reduced filtered water quality
