a separation filter element 5; the bottom end of the coalescent filter element is inserted into the coalescent filter element 3, and the top end of the inner cavity is communicated with the oil box 2;

wherein,

coalescence filter core

3 and 5 bottom of separation filter core all laminate with 11 upper surfaces of baffle, and the baffle 11 upper surface that the space corresponds between coalescence filter core 3 and the separation filter core 5 has seted up delivery port 111.

In order to guarantee the sealing effect of the oil box 2 and the tank body 1, the lower surface of the top cover 4 is fixedly provided with a sealing ring 42, the sealing ring 42 is sleeved outside a box opening at the top end of the oil box 2, and a sealing gasket is arranged between the bottom end face of the oil box 2 and the bottom end face of the top cover 4 and a corresponding step.

It should be noted that, when the whole device is used, the oil liquid is conveyed into the oil liquid cavity 12 by the liquid inlet pipe 14, the oil liquid contacts the coalescing filter element 3 first, water in the oil liquid is coalesced into small water drops through the coalescing filter element 3, the water drops with larger volume are settled to the lower part of the annular space between the separation filter element 5 and the coalescing filter element 3 by the self gravity, the water drops with smaller volume are carried by the oil liquid to flow to the separation filter element 5 when the settlement is not reached, when the oil liquid flows through the separation filter element 5 from outside to inside, the small water drops are intercepted outside the separation filter element 5 to form larger water drops which are deposited to the lower part of the annular space between the separation filter element 5 and the coalescence filter element 3, then the larger water drops flow into the water cavity 13 from the water outlet 111 on the partition plate 11 by means of the self gravity, and are discharged through the water outlet pipe 15, the filtered oil product gradually extends into the oil box 2 through the inner cavity of the separation filter element 5 and is pumped out through the oil outlet pipe 41;

when the coalescence filter element 3 and the separation filter element 5 need to be replaced or cleaned, the top cover 4 can be opened, the top cover 4 is pulled upwards, the separation filter element 5 can be disassembled, the oil box 2 is pulled upwards, the oil box 2 can drive the coalescence filter element 3 to move upwards to be separated from the tank body 1, and the disassembly is quick and convenient;

during the installation, as long as earlier with 2 joints of oil box in the jar mouth, install coalescence filter core 3 again, then install separation filter core 5 and top cap 4 in proper order can, it is quick convenient to install.

As shown in fig. 1-4, a first sleeve ring 6 is fixedly arranged at the top end of the coalescing filter element 3, the outer diameter of the first sleeve ring 6 is larger than that of the coalescing filter element 3, a through hole 21 with a T-shaped cross section is formed in the lower surface of the inner cavity of the oil box 2 corresponding to the first sleeve ring 6, the first sleeve ring 6 and the coalescing filter element 3 are matched with and detachably connected with the through hole 21, and specifically, the first sleeve ring 6 is movably clamped or connected with the through hole 21 in a threaded manner;

a second sleeve ring 7 is fixedly arranged at the top end of the separation filter element 5, the outer diameter of the second sleeve ring 7 is larger than the inner diameter of the first sleeve ring 6, a cover plate 8 is detachably connected to the top of the second sleeve ring 7, a through hole 81 communicated with the inner cavity of the separation filter element 5 is formed in the middle of the cover plate 8, and the top end of the cover plate 8 is fixedly connected with the lower surface of the top cover 4 through an umbrella-shaped support 9; specifically, the second lantern ring 7 is movably clamped or in threaded connection with the cover plate 8.

It should be noted that when the first sleeve ring 6 is movably clamped with the through hole 21, the coalescing filter element 3 can be conveniently taken out before and after the oil box 2 is disassembled, the assembly and the disassembly are rapid and convenient, and the first sleeve ring 6 at the top of the coalescing filter element 3 after the assembly is pressed by the second sleeve ring 7 at the top of the separation filter element 5, so that the vertical movement can not occur;

when the first lantern ring 6 is in threaded connection with the through hole 21, the coalescing filter element 3 can be directly taken out when the oil box 2 is disassembled, and when the coalescing filter element 3 is taken out, the coalescing filter element 3 needs to be rotated to be taken out from the through hole 21, so that the stability is higher, and the operation is more troublesome than clamping;

when the second lantern ring 7 is movably clamped with the cover plate 8, the top cover 4 cannot drive the separation filter element 5 to be taken out when being taken down, and the separation filter element 5 needs to be taken out independently, so that the disassembly operation of the separation filter element 5 and the cover plate 8 is simplified;

when No. two

lantern rings

7 and 8 threaded connection of apron, can directly drive separation filter core 5 when top cap 4 takes off and take out, want to take off separation filter core 5, just need rotate separation filter core 5 and take out it from apron 8 in, stability is stronger.

The above-mentioned embodiments only represent several embodiments of the present invention, and the description thereof is more specific and detailed, but not to be construed as limiting the scope of the present invention. It should be noted that, for those skilled in the art, without departing from the spirit of the present invention, several variations and modifications can be made, which are within the scope of the present invention.
