Problems solved by technology

[0002] The automatic backwash combination filter is a common marine equipment and an important part of the hull. It is an automatic backwash combination filter suitable for filtering various liquid media such as fuel oil, lubricating oil, water, and emulsion. Currently, the existing The structure design of the automatic backflushing combined washing filter is complicated, the equipment space is large, and the manufacturing cost is high. The existing similar equipment adopts oil replenishment and exhaust from the top after recoil. The incoming liquid is downward and the gas is upward, which makes it difficult for the gas to be discharged, causing oil and gas to mix, and the gas is not discharged cleanly, which affects the normal operation of the host equipment, and the effect is not obvious. The existing equipment adopts the technology of differential pressure recoil in the process of use, and the cost is relatively high. high
