TECHNICAL FIELD

[0001] The utility model relates to the field of gas-liquid coalescence filter element, especially to the filter element end cover. BACKGROUND

[0002] The coalescence filter element is a kind of filtering equipment with coalescence material as medium, and is the main element playing the filtering role in coalescer.The tiny oil droplets dispersed in water and other liquids are captured by superfine fibers on the surface of oil-wet filter material, and coalesce to form larger oil beads, and the coalesced oil beads automatically float to the top of coalescer and flow out from the opening at the top of coalescer, and water directly flows outwards through the side wall of filter material, so that the effect of oil-water separation is realized.

[0003] The current gas-liquid coalescence filter element is in the shape of a cylinder, has an end cover at the end, and the end cover is annularly sleeved on the end of the filter element.The end cover and the filter element are fixed by first injecting glue into the end cover and then inserting the end of the filter element into the end cover.

[0004] However, the end cover is in the shape of a cylinder, and the area for storing glue inside the end cover is very small, so glue may be squeezed out during the insertion of the end of the filter element, and glue may overflow.Therefore, the filter element end cover is proposed. CONTENT OF THE UTILITY MODEL

[0009] Optionally, the bottom of the conical cylinder is fixedly provided with a circular ring, and the side close to the middle straight cylinder of the circular ring and the side close to the middle straight cylinder of the ring-shaped plate are both provided with a sealing ring.

[0010] By adopting the above technical scheme, the two sealing rings play a good sealing role when the filter element is inserted into the glue storage chamber, and the phenomenon of glue overflow is less likely to occur.

[0011] Optionally, the lower surface of the annular plate is fixedly installed with a connecting ring.

[0012] By adopting the technical scheme, the connecting ring is arranged, so that the side of the filter core away from the middle straight cylinder of the end cover can be glued with the connecting ring, and the connection strength of the filter core is improved.

[0013] Optionally, a through hole is formed in the connecting ring.

[0014] By adopting the technical scheme, the through hole is arranged, and the circulation of the glue in the glue storage chamber is facilitated.

[0015] Optionally, the lower surface of the annular plate is fixedly installed with a plurality of protrusions arranged in an annular array.

[0016] By adopting the technical scheme, the protrusions are arranged, so that a gap is formed between the top of the filter core and the annular plate, and the glue is easily flowed into the gap between the filter core and the middle straight cylinder.

[0017] Optionally, a glue injection hole is formed in the annular plate, and a plugging bolt is threadedly connected in the glue injection hole.

[0018] By adopting the technical scheme, the glue injection hole is arranged, for example, if the glue is accidentally spilled during the installation of the end cover and the filter core, and at this time, the filter core and the end cover have been connected, the filter core and the end cover do not need to be separated, and the glue can be added into the glue storage chamber through the glue injection hole.

[0019] Optionally, a containing groove in communication with the glue injection hole is formed in the surface of the annular plate, and the head of the plugging bolt is located in the containing groove.

[0020] By adopting the technical scheme, the containing groove is arranged, so that the head of the plugging bolt does not protrude from the upper surface of the annular plate.

[0021] In summary, the utility model has the following beneficial effects:

[0022] 1. Compared with the existing end cover with a cylindrical structure, the cavity for storing glue is larger, the glue overflow phenomenon is reduced, the amount of glue can be increased to improve the bonding strength, and the inclined surface of the conical cylinder and the vertical surface of the middle straight cylinder form a limiting structure to limit the end portion of the filter core. The normal straight cylinder type end cover needs to be larger than the end portion of the filter core by one circle to accommodate the glue, so there is a problem that the end portion of the filter core is not coaxial with the end cover, such as slightly offset to the left or right side, which causes the cavity on one side to be smaller, and the glue to overflow. Therefore, the limiting structure makes the end portion of the filter core coaxial with the end cover without deviation, and better solves the glue overflow problem.

[0023] 2. The utility model discloses a glue injection hole is provided, if the glue spills in the installation process of end cover and filter core middle part by accident, and at this moment, filter core and end cover have formed the connection, then do not need to separate filter core and end cover, and add glue to the inside of glue storage chamber through the glue injection hole.
