Description

Sand filter device for treating raw water for aquaculture

Technical Field

The utility model belongs to the technical field of the aquaculture technique and specifically relates to a handle husky device of straining of raw water for aquaculture.

Background

At present, although the aquaculture industry in China reaches the international leading level in scale and yield, the sustainable development of the industry still faces serious challenges. With the development of the breeding industry, the water environment and resource problems are increasingly severe. The environmental conditions of the aquaculture water area are continuously deteriorated, untreated industrial three wastes, domestic water and agriculture are discharged and enter the water body to cause a series of deterioration of water quality, organisms in the water are firstly endangered, and consequently fishery resources are reduced, diseases are increased, and aquaculture fails. The water environment pollution is severe, the breeding environment is further deteriorated, the occurrence of diseases is increased continuously, and a large amount of medicines and medicaments are added in the breeding process, so that the system of the water body is further disturbed, and the ecological regulation is damaged.

The water quality management center task of the cultured organisms during the culture period is to maintain the good pond environmental condition, scientifically regulate the water quality and provide favorable conditions for the survival and growth of the cultured organisms. The treatment of the culture water plays a crucial role in the success of the culture. In many aquaculture areas, the source water is qualified when the pond is just built, but as the aquaculture progresses, the aquaculture source water is affected to a certain extent due to the increase of aquaculture density and the discharge of sewage, so that some source water is necessary to be simply treated when the aquaculture pond is fed with water, and can be used for aquaculture. When water enters, if a pond special for exogenous water treatment is not available, exogenous water is directly pumped into a culture pond, and enemy organisms, pathogenic organisms and host organisms of pathogens such as wild trash fish, shrimps, crabs, jellyfish and the like enter the pond, so that the culture of aquatic animals is seriously influenced.

Disclosure of Invention

An object of the utility model is to overcome the not enough of above-mentioned prior art, provide a simple structure, convenient operation's processing raw water for aquaculture sand strains device.

In order to realize the purpose, the utility model discloses a technical scheme is: the utility model provides a handle husky device of straining of raw water for aquaculture which characterized in that: comprises a frame, a PVC water filter pipe fixed in the frame, a 80-mesh silk net wrapping the PVC water filter pipe and a 10-mesh nylon net wrapping the frame, wherein water leakage holes are uniformly distributed on the pipe wall of the PVC water filter pipe, the pore diameter of each water leakage hole is 5-15mm, and the density is 40-60 pieces/m²The PVC filter pipe is connected with a PVC outlet pipe.

Furthermore, the PVC water filter pipes are provided with three water filter pipes, and the three water filter pipes are connected with the PVC water outlet pipe through elbows and four-way joints.

Furthermore, the three PVC filter pipes are connected with the PVC water outlet pipe and then are in a 'trident' shape.

Furthermore, the frame is formed by welding steel bars, the length, the width and the height of the steel frame are respectively 6.0 m, 1.5 m and 0.6 m, the diameter of the steel bars is 12mm, and the distance between the steel bars is 30 cm.

The utility model has the advantages that: the water purification device has the advantages that the structure is simple, the influence of environmental factors such as typhoon is not easy to receive, when the water purification device is used, the separation capability of the nylon net and the bolting silk net is utilized, the purification capability of the sand layer is matched, the water for culture can be effectively purified, host organisms of large suspended particles and pathogens in water can be separated from entering the culture pond, the horizontal propagation path of the pathogens is reduced, the occurrence of diseases is effectively reduced, the stability of aquaculture is remarkably improved, the culture success rate is improved, the aquaculture yield is improved, the investment is low, the operation is simple and convenient, and the water purification device has high.

Drawings

The present invention will be described in further detail with reference to the accompanying drawings.

Fig. 1 is a schematic structural diagram of the present invention.

Fig. 2 is an enlarged schematic view of a portion a of fig. 1.

Detailed Description

As shown in figures 1 and 2, the utility model relates to a sand filter device for treating raw water for aquaculture, which comprises a frame 1, a PVC water filter pipe 2 fixed in the frame, an 80-mesh silk net 3 wrapping the PVC water filter pipe and a 10-mesh nylon net 4 wrapping the frame. The wall of the PVC water filtering pipe 2 is uniformly provided with water leakage holes 5, the aperture of the water leakage holes is 5-15mm, and the density is 40-60/m²The PVC filter pipe 2 is connected with a PVC water outlet pipe 6. Specifically, the aperture of the water leakage holes is preferably 10mm, and the density of the water leakage holes is 50/m²。

When the sand filter is used, the sand filter device is buried in a position at least two meters below a filtering sand layer, a water outlet pipe is connected with a water inlet pump of a culture pond, culture water enters the filter pond, is filtered by the sand layer, penetrates through a 10-mesh nylon net and a 80-mesh silk net, then enters a PVC water filter pipe through a water leakage hole, and finally is discharged by a PVC water outlet pipe to enter the culture pond.

The above description is only for the purpose of illustrating the technical solutions of the present invention, and the simple modification or equivalent replacement of the technical solutions of the present invention by those of ordinary skill in the art does not depart from the spirit and scope of the technical solutions of the present invention.
