Open, Inner filter net 5 stretches out from inside outer leaching net 4 and falls, a lubricating oil part enters tank bottoms, a part of Jing through outer leaching net 4
Cross Inner filter net 5 and enter tank bottoms, liquid level declines in oil return pond, it is to avoid oil spilling occurs.
According to an inspection situation, attendant changes in time the filter element of pollution.Filter element after replacing can be cleaned quickly very much,
Reuse.
Analysis is above-mentioned, and this utility model has the following advantages：
The spring of the lock device of preventing oil spill filter element can set marginal value according to the height in live tank drainback pond, work as gravity
After reaching marginal value, spring cannot support the inductor for withstanding Inner filter net, lock device unblock.It is lever principle that inductor is rotated,
The power of unblock can be increased, upper connecting rod is smooth, reduce friction, improve reliability.
Preventing oil spill filter element is inside and outside bilayer, and inside and outside double medium filtration during work, in the case where flow is constant, is improved and filters effect
Really.
Filter element in oil return pond reaches pollution level causes liquid level to rise close top of oil-tank, when oil spilling will occur,
Open lock device, and become monolayer filter element by double-deck filter element is flexible, oil area increases and is twice, and leads to speed oil and improves, and lets out in time
Pressure, prevents oil spilling.
After oil area increase, it is left on inside inner filtering layer after original pollution filtered under intercepting, another part pollutant
Between out filtering layer and inner filtering layer, propose to implement cleaning after filter element, pollutant secondary pollution tank lubrication oil will not occur.
Equipment construction is simple, easy to control sensitive, easy to use, repeats and utilizes, simple, beneficial to popularization.
As known by the technical knowledge, this utility model can be by other essence without departing from its spirit or the reality of essential feature
Apply scheme to realize.Therefore, embodiment disclosed above, for each side, is all merely illustrative, and is not only
's.It is all in the range of this utility model or in the change being equal in the range of this utility model by this utility model bag
Contain.
