Multi-filter cylinder automatic backwashing filter apparatus

Abstract

The invention discloses an automatic backwash filter device with multiple filter cartridges. The casing is divided into upper and lower chambers by a partition. Filter cartridges are installed on the partition in the form of one or more concentric circles. The casing at the lower end of the partition There is a sewage inlet on the side wall, and a clean water outlet on the side wall of the upper shell; the motor of the backwash mechanism drives the main shaft to rotate, the lifting mechanism drives the shaft to lift, and the multi-way connection seat connects the main shaft, the rotating arm and the sewage pipe Together, the main shaft drives the rotating arm to lift and rotate, the sewage pipe is fixed, the upper port of the rotating arm is fixed with a suction nozzle that can be sealed and connected to the water inlet on the partition, and the end of the sewage pipe is connected to an electric sewage valve or a pneumatic sewage valve. The control system controls the action of the motor, lifting mechanism and electric blowdown valve or pneumatic blowdown valve. The invention has the advantages of small volume, large filtering capacity, high production efficiency, good filtering effect of filtered water, good backwashing effect, low backwashing frequency, long service life of equipment, low maintenance rate and saving backwashing water.

Description

Technical field [0001] The invention involves a filter device. Background technique [0002] In the fields of metallurgy, power, petroleum, chemical industry, medicine, food, printing and dyeing, paper, urban water supply, central air conditioning, river water purification, medium water treatment, agricultural irrigation, sewage treatment and other fields, filters are widely used in various lubrication, cooling, productionThe filtering and separation of fluids such as water, emulsification solution in the system, and many companies still use traditional filters. [0003] Most of the filter structure of the traditional filtering equipment uses a single filter filtering structure or the multi -filter filtering structure with multiple different filter elements.Multi -filter element filtering equipment layers of filtration, the filtration effect is good, but its filtration water is small, the water production of the filtering equipment is small, it is not easy to clean after the filt...

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
