Worm filter device with external filters

Abstract

The invention discloses a worm filter device with external filters. The device comprises a water wing and the filters, the filters comprise V-shaped bases, and the sides, facing water inlets, of the V-shaped bases are V-shaped side walls; water which enters the water inlets is divided through the V-shaped side walls, cavities are formed in the V-shaped bases, and two positioning bosses are symmetrically arranged in the cavity of each V-shaped base; M-shaped bosses are arranged on the inner walls, close to valves, of the V-shaped bases, J-shaped worm filter plates are embedded in the positioning bosses, and each J-shaped worm filter plate and the two sides of the corresponding V-shaped base form a worm filter cavity; a U-shaped insertion plate which is matched with the corresponding M-shaped boss is arranged at one end of each J-shaped worm filter plate, and accordingly a drainage labyrinth is formed; a first needling wall, a first baffle, a second needling wall, a second baffle and a third needling wall are arranged at one side of each worm filter cavity in the length direction of the corresponding J-shaped worm filter plate, end covers are arranged on the upper end surfaces of theV-shaped bases, water pipes are arranged on the end pipes, and the end, away from the corresponding end cover, of each water pipe extends into water. The worm filter device with the external filtersis simple in structure, the external filters are taken out and cleaned conveniently, and the working efficiency is high.

Description

technical field [0001] The invention relates to fishery equipment, in particular to an insect filter castle with an external filter. Background technique [0002] There will inevitably be various water insects in fish ponds. The existence of water insects will rob the water of oxygen. Excessive reproduction will cause water pollution and cause harm to the growth of fish in fish ponds. The current insect filter equipment is relatively complicated. Set the light to attract fish and insects, and then set the filter inside the equipment. It is very troublesome to clean and replace. The service life of the equipment is short and more manpower is required, the cost is high, and the work efficiency is low. Contents of the invention [0003] The technical problem to be solved by the present invention is to propose a kind of insect filter castle with an external filter, which is not only simple in structure, easy to operate, low in cost, safe and reliable, long in service life, and...
