The chassis 56 of Inner filter net 5 is provided with through hole (such as Fig. 5, Fig. 8, unmarked), and stopper 91 should from the insertion of the top of chassis 56
In through hole.
The one end of drawstring 76 is connected to the second end of locking bar 71, and the other end is connected with stopper 91 through through hole, passes through in practice
Stopper 91.For the ease of connection, the second end of locking bar 71 is provided with draw ring 75, and drawstring 76 is connected with the draw ring 75.
When moving back and forth, in order to limit its mobile route, the present embodiment also includes lead column 8 to drawstring 76, and lead column 8 is consolidated
Due to the lower section of chassis 56 near above-mentioned lead to the hole site, drawstring 76 in lead column 8, to limit the position of drawstring, for example can be with
It is outer surface that drawstring 76 is covered on lead column 8, can also be that the outer surface in lead column 8 is provided with gathering sill along its circumference, draws
Rope 76 is in gathering sill.
In order to improve the sealing effectiveness of stopper 91, stopper 91 is rubber stopper, as shown in figure 8, it is in integrally inverted circular cone
Mesa-shaped；The through hole that it is inserted also is in inverted circular cone shape.For the ease of the pull-up stopper 91 of draining bar 93, the top of stopper 91 sets
There is stopper draw ring 92.
When the present embodiment is located in fuel tank, need locking bar 71 to extract from location hole 420, be lifted up stopper draw ring 92
, drawstring 76 pulls locking bar 71 to depart from location hole 420 and compression spring 74.For the ease of the operation, this utility model is also carried
For a kind of draining bar, as shown in figure 9, draining bar embodiment of the present utility model includes the body of rod 93 and the drawing positioned at the one end of the body of rod 93
Hook 931.When idle, the link 932 of the other end of the body of rod 93 can be hung on any suitable position.
In addition, this utility model also provides a kind of oil lubricating system, it includes fuel tank, located at multiple filters of fuel tank internal
Core, filter element is shown in Fig. 4-Fig. 8 and prevents oil spilling filter element, upper backup pad of the vertical distribution of multiple filter elements 200 in fuel tank 1
On, current big flow fuel tank, for the labour force that reduces cost and maintenance are changed, oil return pond 15 adopts open type oil return
Pond, for example, formed by being provided with through hole at the top of fuel tank 1, and the oil lubricating system can also referred to as have the thin oil of draining bar
Lubricating system.Also include the draining bar shown in Fig. 9 simultaneously.
In application drawing 4- embodiment illustrated in fig. 9, following steps are may be referred to：
The present embodiment is cleaned up, Inner filter net 5 is in inside outer leaching net 4, and by the inserted base of locking bar 71 of lock device 6
In 42 location hole 420, the state of Inner filter net 5 is locked, prevent it from skidding off.
Install in the tank drainback pond of filter element to oil lubricating system, now lubricating oil liquid level is relatively low in oil return pond.Oil return
Lubricating oil falls into Inner filter net 5 in pond, after filtering into the space between the outside of Inner filter net 5 and outer leaching net 4, because of two sealing rings
53/55 sealing function, lubricating oil can only be discharged by outer leaching net 4, into tank bottoms.
When the pollutant that the present embodiment is intercepted are more, go deep into hooking the plug of stopper 91 inside Inner filter net 5 using draining bar
Sub- draw ring 92, firmly one carries, and opens lock device 6, and Inner filter net 5 stretches out from inside outer leaching net 4 and falls, and a lubricating oil part is through outer
Filter screen 4 enters tank bottoms, and a part enters tank bottoms, flow area increase through Inner filter net 5；In oil return pond under liquid level
, there is no oil spilling in drop.
Finally, according to field test situation, attendant changes in time the present embodiment of pollution, and the filter element after replacing can be with
Quickly clean very much, reuse.
Analysis is above-mentioned, and this utility model has the following advantages：
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 when causing liquid level to rise close top of oil-tank oil spilling occurs, using letting out
Beam hanger gos deep into inside inner filtering layer, hooks the draw ring of rubber stopper, firmly mentions, and opens lock device, and double-deck filter element is flexible to become single
Metafiltration core, oil area increasing is twice, and leads to speed oil and improves, and timely pressure release 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.
