Description

Precision filter convenient to wash

Technical Field

The utility model relates to a filter technical field specifically is a precision filter convenient to wash.

Background

The filter is a precision device which directly intercepts impurities in media such as water and oil by a filter screen, mainly removes suspended matters and particles in the media to reduce turbidity, purify water and oil, reduce generation of system dirt, bacteria, algae, rust and the like, purify the media such as water and oil, and protect other devices of the system to normally work. The existing filters adopt single-stage filtration, when sewage enters the filters for filtration, an inner filter screen of the filters intercepts suspended matters in the sewage, and when the suspended matters block the filter screen holes and reach a certain amount, the resistance of the filter screen is increased to form pressure difference; then, a differential pressure meter detects and outputs signals, the controller receives the differential pressure signals and sends out a cleaning instruction, a sewage suction motor on the filter operates and drives a sewage suction pipe to rotate, a suction nozzle sucks suspended matters of the filter screen, and the flux of the filter screen is recovered. However, for a filter with only one-stage filtration, when the content of suspended matters in sewage is greater than 100ppm, that is, the sewage contains a large amount of suspended matters or the requirement on filtration accuracy is higher than 80um, a good filter screen flux recovery effect cannot be achieved even if a sewage suction motor and a sewage suction pipe are matched for sucking the suspended matters, the filter screen can be blocked quickly, the sewage suction capacity can be reduced quickly, and the use requirement cannot be met; and even if multi-stage filtration is arranged, when the sewage contains a large amount of suspended matters, the filtration work of the whole filter has to be stopped because the filter screen of the first stage filtration is easy to be blocked until the filter screen of the first stage filtration is repaired or replaced, but a new filter screen still can not work normally for too long time and can be blocked, and the filtration efficiency is seriously influenced.

Chinese patent (publication No. CN 204261432U, bulletin date: 2015.04.25) discloses a self-cleaning precision filter, which comprises a motor, a rotating shaft and a support, wherein the motor is fixed on the upper surface of a filter shell through the support, the lower end of the motor is connected with the rotating shaft, a cleaning brush is installed at two ends of a connecting rod, a water outlet is welded at the upper right corner of the filter shell, a filtering device is installed inside the support frame, the connecting rod is installed at the lower end of the rotating shaft in a penetrating manner, the support is tightly welded inside an inner cavity of the filter shell, the support is welded on the surface of the filter shell, a filter screen is installed at a water inlet of the self-cleaning precision filter, a filtering layer is arranged inside a water tank, water is filtered thoroughly, the surface of the inner cavity. The filtering device is cleaned by the cleaning brush on time, so that the filtering device is easy to damage and generate new pollution, and the cleaning brush is inconvenient to implement.
