Embodiment 1

[0027] like figure 1 and 2 As shown, the present invention provides a fully automatic backwashing self-cleaning filter for filtering lubricating oil and fuel oil, including a filter housing 1, an outer cover 2, a backwashing device, a differential pressure indicator 12, and a filter element assembly. The filter housing 1 includes all pipeline connections and the connecting ports of the air-releasing plug 13 , the residual plug 14 and the differential pressure indicator 12 . The outer cover 2 and the shell 1 are tightened by bolts. A backwashing device with double flushing arms (5 and 6) is built into the housing 1. The function of the backwashing device can be checked through a sight glass 15 on the housing 2 . A differential pressure monitor is optional to measure the differential pressure between the filter inlet and outlet. This pressure differential across the filter increases as the filter element becomes increasingly fouled. The differential pressure indicator 12 vi...

Abstract

The invention discloses a full-automatic backwashing self-cleaning filter for filtering lubricating oil and fuel oil. The full-automatic backwashing self-cleaning filter comprises a filter shell, an outer cover, a backwashing device and a filter element assembly, the top of the filter shell is provided with an outer cover, the filter shell is internally provided with a filter element assembly, the backwashing device comprises an impeller, a turbine worm transmission device and double washing arms, the double washing arms comprise an upper washing arm and a lower washing arm, one side of the impeller is provided with a filter inlet, and the other side of the impeller is provided with the turbine worm transmission device; and a hollow pipe is installed on one side of the turbine worm transmission device, a gear is connected to the hollow pipe in a sleeved mode, a lower washing arm is connected to the top of the gear, an upper washing arm is installed on the top of the hollow pipe, the filter element assembly is composed of a plurality of candle-shaped filter elements arranged in parallel, the candle-shaped filter elements are located between the upper washing arm and the lower washing arm, and a filter outlet is formed in one side of the candle-shaped filter element. The filter is free of manual maintenance for a long time, the labor cost is reduced, the filter element consumption is reduced, and the environment is better protected.

Description

technical field [0001] The invention relates to the technical field of filter cleaning, in particular to a fully automatic backwashing self-cleaning filter for filtering lubricating oil and fuel oil. Background technique [0002] The liquid filter commonly used in the market is generally a manual duplex filter. The filter has two chambers. When the filter element of one chamber is put into operation, the filter element of the other chamber is used for standby. The filter filters the medium through the filter element, and the large impurity particles stay on the inlet side of the filter element, while the clean medium comes from the other side of the filter element. The working state of the two chambers can be manually switched through the conversion valve on the filter, the spare chamber is put into work, the working chamber is cut off, and the filter element of this chamber is manually maintained and replaced. [0003] This kind of filter has a simple structure and can mee...
