A replaceable fine filter

Abstract

The invention relates to a high-efficiency replaceable secondary filter. The high-efficiency replaceable secondary filter comprises a tank body, a tank cover and a lifting device; the lifting device is arranged on the outer side of the tank body; the lifting device comprises an oil cylinder, an ejector rod, a base, a support rod, a slide rail and a slide block; an oil outlet is formed in the bottom end of the tank body; a baffle plate, a funnel, a filter element, a third bracket and a fourth bracket are arranged in the tank body; the filter element comprises an upper plate, a lower plate, an inner skeleton and an outer skeleton; multiple filter layers are arranged between the inner skeleton and the outer skeleton; an oil inlet is formed in the tank cover; the tank cover and the tank body are tightly connected; a stirring shaft is arranged at the middle part of the tank cover; and the stirring shaft is provided with a filter paper tray and a filter module. The high-efficiency replaceable secondary filter is excellent in oil filter effect; and filter papers can be replaced.

Description

Technical field [0001] The invention relates to a replaceable fine filter. Background technique [0002] During the long-term operation of steam turbines in power plants and power stations, water, dust and solid particles will inevitably be mixed into the turbine oil due to various complicated reasons, accelerate the oxidation of the oil, and promote the formation of foam, fouling and sludge, causing oil The serious emulsification of the oil makes it difficult to separate the oil and water, and reduces the oil's lubrication, anti-wear, heat dissipation, dispersion, and cooling properties. At the same time, it causes the corrosion and wear of the metal parts in the steam turbine, which affects the safe operation of the steam turbine, and the impurities contained in the oil must be purified. Summary of the invention [0003] In order to solve the above problems, the present invention provides a replaceable fine filter. [0004] A replaceable fine filter includes a tank body, a tank ...

[0002] During the long-term operation of steam turbines in power plants and power stations, moisture, dust and solid particle impurities will inevitably be mixed into the turbine oil due to various complicated reasons, which will accelerate the oxidation of oil and promote the formation of foam, scale and sludge, causing oil The serious emulsification of the oil makes it difficult to separate oil and water, which reduces the performance of oil lubrication, anti-wear, heat dissipation, dispersion, and cooling.

At the same time, it will cause corrosion and wear of the metal parts in the steam turbine, which will affect the safe operation of the steam turbine, and the impurities contained in the oil must be purified
