Problems solved by technology
[0004] When the existing filter is detached from the water tank, the sludge collected from the inside of the filter is detached from the inside of the water tank, and there is a problem of treating the sludge inside the water tank
[0005] In addition, the existing filter has the following problems, the oil film is only decomposed on the outlet side of the water outlet, and the oil film generated on the water surface cannot be removed well, and the water outlet The oil film stop zone is formed on the rear side of the water outlet, and a vortex is generated in the water outlet, so that it is difficult to realize the ejection of the fluid

The present invention provides a filter. The filter of an embodiment of the present invention includes: an upper body filled with filter material; a lower body arranged on the lower side of the upper body, wherein the upper and lower parts are open; and an anti-skid release unit which is arranged inside the lower body to allow a sludge and a fluid to flow into the lower body and prevent the sludge from slipping off the inside of the lower body. The anti-skid release unit includes: a support plate, which is fixed inside the lower body, wherein a through hole is formed in the center; a center tube connected to the upper part of the support plate to form a lower hole communicating with the through hole, at least one connecting hole is formed on one side; and a reflux ball moving inside the center tube to selectively open and close the lower hole to prevent the fluid from flowing back.
Description
technical field [0001] The present invention relates to a filter. Background technique [0002] In general, the filters used inside the tank for filtering water in the tank include: side filters, which are attached to the wall of the tank; and sponge filters, and bottom filters, which are used at the bottom of the tank. [0003] Wherein, the fluid flowing in by using the bottom surface filter at the bottom of the water tank passes through the filter material inside and returns to the inside of the water tank through the water outlet by means of the air electric pump or the submersible electric pump. [0004] When this conventional filter is detached from the water tank, the sludge collected from the inside of the filter is detached to the inside of the water tank, and there is a problem of treating the sludge inside the water tank. [0005] In addition, existing filters have the following problems. The oil film is only decomposed on the outlet side of the water outlet, and ...
