Automatic back-flushing filtering device

Abstract

The invention provides an automatic backwashing filtering device, comprising a cycloidal pinwheel reducer, an upper cylinder and a lower cylinder, the cycloidal pinwheel reducer is communicated with a lubricating oil pump, and the cycloidal pinwheel reducer is connected to the top through bolts The bracket is fixedly connected, the top bracket and the middle bracket are fixedly connected by bolts, the output shaft and the transmission shaft of the cycloid reducer are fixedly connected by a coupling, and there is a diaphragm between the upper cylinder and the lower cylinder. The plate and the transmission shaft are fixedly connected by keys, and there are several perforations on the diaphragm. The backwashing process of the invention consumes less water, realizes continuous and automatic filtration, and can be safe, reliable, and safe for a long time under specified environmental conditions. It runs smoothly and meets the requirements of various performance and working conditions, especially in the case of poor water quality, it can still work smoothly and continuously.

Description

technical field [0001] The invention relates to the technical field of filtration, in particular to an automatic backwashing filtration device. Background technique [0002] Backwash filter is a kind of filter that directly intercepts impurities in water, removes suspended solids and particulate matter in water, reduces turbidity, purifies water quality, reduces system dirt, bacteria and algae, rust, etc., to purify water quality and protect other equipment in the system Precision equipment that works properly. [0003] For filters that cannot be backwashed automatically, after the filter element is clogged, it is necessary to disassemble the filter and take out the filter element for cleaning, resulting in a pause in production and a decrease in work efficiency. When the medium realizes the filter function, the pollution to the environment is particularly serious; the water of the automatic backwash filter enters the body of the self-cleaning filter from the water inlet.

[0003] For filters that cannot be backwashed automatically, after the filter element is clogged, it is necessary to disassemble the filter and take out the filter element for cleaning, resulting in a pause in production and a decrease in work efficiency. When the medium realizes the filter function, the pollution to the environment is particularly serious; the water of the automatic backwash filter enters the body of the self-cleaning filter from the water inlet. Due to the intelligent design, the system can automatically identify the degree of impurity deposition and automatically signal to the sewage valve. Sewage

[0004] Existing backwash filters, especially high-pressure and high-flow backwash filters, currently mainly rely on imported products, but the cost of using imported products is too high, difficult to maintain, and has large limitations. At present, there are only a few backwash filters in my country Produced by the manufacturer, the workmanship is rough, the reliability is low, the filtration accuracy cannot meet the requirements, it is easy to damage, and the maintenance cost is high
