Wherein, the crude oil impurity filtering device further include have lower liquid bucket 27, outlet tube 28, the second filter frame 29, web plate 30, Catheter 31 and wing bolt 33;Twice liquid buckets 27 are fixed in 1 bottom of the first filter frame, and are located at 14 both sides of partition board;Outlet tube 28 are fixed in lower 27 bottom of liquid bucket, and the second filter frame 29 coordinates with the suit of outlet tube 28, and outlet tube 28 offers the first threaded hole 32, the second filter frame 29 offers the second threaded hole 34, and wing bolt 33 is spirally connected with the first threaded hole 32, the first threaded hole 32, Web plate 30 is fixed in bottom in the second filter frame 29, and catheter 31 is fixed in 29 bottom of the second filter frame.
Second filtering screen frame 26 carries out secondary filter by web plate 30 to crude oil, by the subtle sundries of first time filtration residue For re-filtering, since crude oil has carried out preliminary filtering, web plate 30 is not easy to block.
Wing bolt 33 is rotated counterclockwise, wing bolt 33 is screwed out out of first threaded hole 32, at this time just can be by second Filter frame 29 is removed from outlet tube 28, and the sundries on web plate 30 is cleared up, in this way, the sundries in crude oil will be thorough Filtering, to not interfere with follow-up refinery operations.
Wherein, which further includes having the first sliding sleeve 36, the first slide bar 37, third elastic component 39, One pull rod 40 and fixture block 41;First the 11, second opening of opening, 24 top offers first movement slot 38, and the first slide bar 37 is affixed In in first movement slot 38;First sliding sleeve 36 is embedded in the first pull rod 40, and is slidably connected with the first slide bar 37;First pull rod 40 1 End is connect by third elastic component 39 with 38 top of first movement slot, and fixture block 41 is fixed in 40 bottom of the first pull rod.
The first pull rod 40 is pulled to move upwards, since the first sliding sleeve 36 and the first sliding sleeve 36 are slidably connected, first draws Bar 40 can be moved upwards smoothly, and third elastic component 39 will be compressed, and the first fixture block 41 is taken in first movement slot 38, this moment First filtering screen frame 13, second is filtered screen frame 26 to promote in the first filter frame 1, then removes the external force of the first pull rod 40, by It is acted in the elastic force of third elastic component 39, fixture block 41 will move downward, to carry out first movement plate 10, the second movable plate 23 It is fixed, so ensure the first filtering screen frame 13, second filter screen frame 26 crude oil filter process will not accidental movement, influence crude oil The filter effect of sundries.
Wherein, which further includes having the second sliding sleeve 42, the second slide bar 43, mobile bar 45 and snap-gauge 47;14 middle part of partition board offers the second shifting chute 44, and the second slide bar 43 is fixed in the second shifting chute 44;Second sliding sleeve 42 is embedded in Mobile bar 45, and be slidably connected with the first slide bar 37;14 both sides of partition board offer a word hole 46;Snap-gauge 47 is fixed in mobile bar 45 tops, and be slidably connected with a word hole 46.
Mobile bar 45 is pulled to move right, since the second sliding sleeve 42 and the first slide bar 37 are slidably connected, mobile bar 45 It will steadily move right, therefore snap-gauge 47 is removed along a word hole 46 on 14 right side of partition board, snap-gauge 47 consolidates second baffle 16 It is fixed, since gravity can push second baffle 16 when preventing crude oil from falling, cause the second filtering screen frame 26 to be replaced impacted.
Wherein, which further includes having draw ring 48;First movement plate 10, the second movable plate 23 are affixed There is draw ring 48, the first filtering screen frame 13, second, which filters screen frame 26, preferably to pull out the first filter frame 1 by draw ring 48.
Wherein, the shape in 41 outside of fixture block is arc-shaped, since the shape of fixture block 41 is arc-shaped, the first filter screen Frame 13, second, which filters the process that screen frame 26 is put into, need not continue to pull the first pull rod 40, alleviate working dynamics.
The application is described above in association with specific embodiment, it will be appreciated by those skilled in the art that this A little descriptions are all exemplary, and are not the limitation to the application protection domain.Those skilled in the art can be according to the application Spirit and principle various variants and modifications are made to the application, these variants and modifications are also within the scope of application.
