A mobile strong magnetic filter

Abstract

The invention discloses a movable strong magnetic filter. The strong magnetic filter comprises a filter body, wherein a plurality of easily-disassembled strong magnetic rods are mounted inside the filter body; an oil inlet, an oil outlet and a movable fixing device are arranged on the filter body; a valve is arranged at each of the oil inlet and the oil outlet. The strong magnetic filter is good in filter effect and convenient and flexible to use, can movably cooperate with an oil filter for filtering, can be cleaned by easily dismounting, greatly reduces labor and the cost for cleaning and maintenance, and greatly reduces the equipment cost and the use and maintenance cost of filtering work as a whole.

Description

technical field [0001] The invention relates to liquid filtering equipment, in particular to a strong magnetic filter. Background technique [0002] The steam turbine unit in a power plant needs to be lubricated with turbine oil, which has been filtered many times to meet the operating standards. However, during the working process of the steam turbine, the impact and wear caused by the mutual movement of the gears will easily cause metal debris to peel off. For a long time, a large amount of metal debris mixed into the turbine oil will cause great danger to the safety of the generator set; at the same time, metal iron chips have a catalytic effect on the aging of the turbine oil, accelerating the aging of the turbine oil, making the The turbine oil system produces a large amount of oil sludge; moreover, the metal iron filings gather into groups under the action of the oil sludge, causing key components such as pressure distribution valves to be stuck in the hydraulic speed ...

[0002] The steam turbine unit in a power plant needs to be lubricated with turbine oil, which has been filtered many times to meet the operating standards. However, during the working process of the steam turbine, the impact and wear caused by the mutual movement of the gears will easily cause metal debris to peel off. For a long time, a large amount of metal debris mixed into the turbine oil will cause great danger to the safety of the generator set; at the same time, metal iron chips have a catalytic effect on the aging of the turbine oil, accelerating the aging of the turbine oil, making the The turbine oil system produces a large amount of oil sludge; moreover, the metal iron filings gather together under the action of the oil sludge, causing the key components such as the pressure distribution valve to be stuck in the hydraulic speed control system, which is likely to cause the system to be paralyzed

[0003] Therefore, to ensure the normal operation of the steam turbine unit, it is necessary to filter the turbine oil. At present, the filter paper, the metal mesh filter element filter, the electrostatic oil filter and the frame-type strong magnetic filter are used in the oil tank to filter the turbine oil. For the filter, the metal particles below 5μm cannot be removed by the general oil filter, and the frame type strong magnetic filter needs to be used for filtering, and the frame type strong magnetic filter needs to be installed in the oil tank, which can only be installed during overhaul Or cleaning, so its cost is relatively high, and each unit needs to invest a corresponding cost. At the same time, the frame type strong magnetic filter needs to be cleaned inside the oil tank, which is easy to pollute the oil again, which is very inconvenient, and the overall use and The maintenance cost is very high and cannot meet the requirements of modern use
