Abstract

The utility model discloses a filtering device for sea water aquiculture larva rearing, relating to water filtering devices. The bottom part of a filtering tank is laid with a layer of cobblestones; alayer of filter screen is covered on the cobblestones and the meshes of the filter screen do not allow sand grains passing through; the upper part of the filtering screen is laid with a sand grain layer; the upper part of the filtering tank is provided with a water inlet pipe; the position of the side wall of the filtering tank near the bottom part thereof is provided with water outlets which arefixed outside the water outlets; a plurality of water outlets are arranged parallelly at the position of the wall of the filtering tank near the bottom part of the filtering tank; a plurality of water outlet pipes penetrate through the water outlets and extend into the cobblestone layer to the position of the internal surface adjacent to the opposite side wall; a plurality of water inlets are uniformly distributed on the axially-equidistant radial walls of each water outlet pipeline extending into the cobblestone layer; and the external ends of the water outlet pipes are communicated with a water outlet general pipe through tee joints and elbows. The filtering device for sea water aquiculture larvae rearing has the advantage that the arrangement of a plurality of pipes and a plurality ofholes leads water in the whole tank to fully dynamically flow without dead water phenomena.

Description

A kind of filter device for raising seawater seedlings

Technical field:

The utility model relates to a water filtering device.

Background technique:

At present, marine aquaculture has become a major industry, so seawater seedling cultivation has also become the most important leading technology in the industry. Seawater nursery is carried out by building a nursery pond on land and pouring seawater into it, but it is required that the seawater should not be accompanied by debris, especially mud, because nursery ponds are generally built on the seashore, and pumping and irrigation equipment can only be located a few meters to a few meters away from the beach. The water is pumped at a distance of ten meters. Because of the ebb and flow of seawater, the debris on the beach will move accordingly, and it is easy to be sucked by the pump, which is not conducive to seedling cultivation. Therefore, the seedling water needs to be filtered.

Now the filter pool is set to lay a layer of pebbles on the bottom, and a layer of filter screen is covered on the pebbles. A water outlet is arranged at the bottom of the pool, and the water outlet pipe is fixed outside the water outlet.

The disadvantage of this arrangement is that the water flow away from the water outlet is concentrated and unobstructed, while the water flow in other parts far away from the water outlet, especially the corners of the pool, basically does not move and becomes stagnant water, which affects the overall water quality.

Invention content:

The purpose of the utility model is to overcome the above defects and provide a filter device for raising seawater seedlings.

The solution of the utility model is: a plurality of water outlets are arranged side by side on the wall of the filter pool near the bottom of the pool, and a plurality of water outlet pipes extend into the cobblestone layer through the corresponding water outlets and extend to the position adjacent to the inner surface of the opposite side wall. A plurality of water inlet holes are evenly distributed on the axially equidistant radial wall of the pipeline entering the cobblestone layer, and the outer end of the water outlet pipe is connected with the water outlet main pipe through a tee and an elbow.

The utility model has the advantages that: multi-pipe and porous are arranged, so that the flowing water in the whole pool can flow in a full dynamic manner without stagnant water phenomenon.

Description of drawings:

Accompanying drawing is the structural representation of the utility model.

Detailed ways:

The structure of the present utility model is: the filter tank (3) is set to lay a layer of pebbles at the bottom, and a layer of filter screen (5) is covered above the cobblestones, and its mesh size does not allow sand to pass through, and a layer of sand layer (4) is laid on the top of the net. ), the upper part of the filter tank (3) is provided with a water inlet pipe (2), the side wall of the filter tank (3) is provided with a water outlet near the bottom of the pool, and the water outlet pipe (1) is fixed on the outside of the water outlet, and it is characterized in that the filter tank ( 3) Multiple water outlets are arranged side by side on the wall near the bottom of the pool, and multiple water outlet pipes (1) extend through the corresponding water outlets into the pebble layer (6) and extend to the position adjacent to the inner surface of the opposite side wall, and each water outlet pipe (1) A plurality of water inlet holes are evenly distributed on the axially equidistant radial wall of the pipe extending into the cobblestone layer (6), and the outer end of the water outlet pipe (1) realizes pipe communication with the water outlet main pipe through a tee and an elbow.

Through the porous water inlet, the full circulation of filtered water at the bottom of the pool is realized.
