Description of drawings
Fig. 1 is a kind of cross-sectional view that is used for the magnetic filter of hydraulic oil container of the utility model.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is described further, but not as the qualification of the utility model.
As shown in Figure 1; A kind of magnetic filter that is used for hydraulic oil container of the utility model comprises fixing device 1 and greasy dirt container 2, and fixing device 1 is fixedly connected on greasy dirt container 2 bottom of hydraulic oil container 3; Wherein, Also comprise magnetic part 4, greasy dirt container 2 bottoms are provided with opening 21, and the opening 21 of magnetic part 4 through greasy dirt container 2 bottoms stretches in the greasy dirt container 2 and the opening 21 of sealing greasy dirt container 2 bottoms.
The working principle of the utility model is: because the impurity of hydraulic oil is generally heavy than hydraulic oil; So can be deposited on the bottom usually; The magnetic filter of the utility model is connected with the bottom of fuel tank 3 through fixing device 1; Opening is arranged at hydraulic oil container 3 bottoms, makes iron filings in the hydraulic oil get in the greasy dirt container 2 with hydraulic oil and is stretched into magnetic part 4 absorption in the greasy dirt container 2, plays the effect of filtration hydraulic oil; Thereby when the greasy dirt in the greasy dirt container 2 is accumulated to a certain degree, can take out the opening 21 that magnetic part 4 is opened greasy dirt container 2 bottoms, the greasy dirt in the greasy dirt container 2 is flowed out from bottom opening 21.
Further; On the technique scheme basis; Fixing device 1 can be a flange; Flange is fixed on the bottom of hydraulic oil container 3 with greasy dirt container 2, connects through flange to make the cross section of greasy dirt container 2 can process circle, makes that like this impurity iron filings in the hydraulic oil possibly reduce what the edge of greasy dirt container 2 gathered.
Further, on the technique scheme basis, funnel shape can be processed in greasy dirt container 2 bottoms, and funnel shaped greasy dirt container 2 can make things convenient for greasy dirt to discharge from the bottom opening 21 of greasy dirt container 2.
Further; On the technique scheme basis; Greasy dirt container 2 can be processed by transparent material, processes greasy dirt container 2 with transparent material and can conveniently observe the greasy dirt storage in the greasy dirt container 2, to determine when that conveniently the bottom opening 21 of opening greasy dirt container 2 carries out greasy dirt and discharges.The scale of the one greasy dirt upper limit can be set on the greasy dirt container in actual the use; Greasy dirt container 2 bottoms form under the long-time cumulative function one deck greasy dirt mixing material and top fluid can produce a separatrix, and the opening 21 that when this separatrix rises to upper limit scale, need open greasy dirt container 2 bottoms carries out greasy dirt and discharges.
Further; On the technique scheme basis; Magnetic part 4 mainly adsorbs end 41 permanent magnet 42 outer with placing the greasy dirt container by the magnet case that stretches into greasy dirt container 2 to be formed, and permanent magnet 42 holds 41 bottoms to be connected with magnet case absorption, and wherein magnet case absorption end 41 can be an irony club; The one of which end is stretched in the greasy dirt container 2 by the bottom opening 21 of greasy dirt container 2; The other end is stayed outside the greasy dirt container 2, and permanent magnet 42 is connected with ends of staying outside the greasy dirt container 2 as the club of magnet case absorption end 42, and the irony club is passed to the magnetic of permanent magnet 42 in the greasy dirt container 2; An end that makes club stretch into greasy dirt container 2 is realized the effect of absorption iron filings; When needs are got rid of greasy dirt, can separate permanent magnet 42 earlier and, the irony club lost magnetism, thereby make the iron filings that are adsorbed on the irony club fall into greasy dirt and be discharged from greasy dirt as the irony club of magnet case absorption end 41.
Further, on the technique scheme basis, also comprise greasy dirt guiding channel 5, greasy dirt guiding channel 5 is inside and outside from greasy dirt container 2 bottom UNICOM greasy dirt containers 2, and opens and closes through magnetic part 4 controls.In practical application, can one packaged unit 43 be set at ends of staying greasy dirt container 2 outsides as the irony club of magnet case absorption end 41; Packaged unit 43 is provided with through hole 431; The opening of packaged unit 43 sealing greasy dirt containers 2 bottoms during daily use; And through hole 431 is closed the greasy dirt that makes in the greasy dirt container 2 and can not flowed out from opening 21, when needs are discharged greasy dirt, can open the through hole 431 on the packaged unit 43, and greasy dirt is flowed out from through hole 431.On this basis; Cooperate the above-mentioned greasy dirt container 2 that contains funnel-shaped bottom portion; As the internal diameter coupling of external diameter with the opening 21 of greasy dirt container 2 funnel-shaped bottom portion of the irony club of magnet case absorption end 41, the opening 21 of greasy dirt container 2 funnel-shaped bottom portion was used as the irony club obstruction of magnet case absorption end 41 when packaged unit 43 was closed in rotary manner.Irony club obstruction as magnet case absorption end 41 is provided with a steering channel (not marking in the drawings); This steering channel and through hole 431 UNICOMs when the irony club as magnet case absorption end 41 rotates to predetermined angle; Packaged unit 43 rotations and then drive are as the irony club rotation of magnet case absorption end 41 when needing to discharge greasy dirt; Make steering channel and through hole 431 UNICOMs; Discharge via through hole 431 thereby make in the greasy dirt bootstrap groove; Wherein, can also be provided with that screw thread or position structure are fixed with convenient irony club as magnet case absorption end 41 in contacting point and locate when rotating as the irony club of magnet case absorption end 41 and the opening 21 of the funnel-shaped bottom portion of greasy dirt container 2.
Further, on the technique scheme basis, through hole 431 can connect the flow direction of a sebific duct with the greasy dirt of guiding discharge, and avoiding greasy dirt to discharge is sputter to occur.
The above is merely the utility model preferred embodiment; Be not thus the restriction the utility model claim; So the equivalent structure that all utilization the utility model specifications and diagramatic content have been done changes, and all is included in the protection domain of the utility model.
