Embodiment 1

[0030] Such as Figure 1~Figure 5 Shown, a kind of high-efficiency sewage collection and discharge device for shrimp culture ponds, including shrimp pond 2, screen cover 15, filter layer 12, sewage pipe 13, screen cover 15 is connected with filter layer 12, and filter layer 12 is provided with water barrier 14. A rubber plate 21 is connected to the bottom of the filter layer 12, and the rubber plate 21 is placed on the bottom surface of the shrimp pond 2, and the filter layer 12 is connected to the sewage pipe 13 through the sewage outlet 11.

[0031]The bottom of the shrimp pond 2 is conical. Due to the existence of taper and gravity, the sediment will gather along the bottom of the pond to the center of the pond. The centrifugal effect of the inner circulation of the breeding pond will make the sediment gather in the center of the bottom of the shrimp pond 2. The sediment is the feeding The residual bait and the metabolites of prawns. During the sedimentation process, the se...

Embodiment 2

[0043] Such as Figure 1~Figure 5 Shown, a kind of high-efficiency sewage collection and discharge device for shrimp culture ponds, including shrimp pond 2, screen cover 15, filter layer 12, sewage pipe 13, screen cover 15 is connected with filter layer 12, and filter layer 12 is provided with water barrier 14. A rubber plate 21 is connected to the bottom of the filter layer 12, and the rubber plate 21 is placed on the bottom surface of the shrimp pond 2, and the filter layer 12 is connected to the sewage pipe 13 through the sewage outlet 11.

[0044] The bottom of the shrimp pond 2 is conical. Due to the existence of taper and gravity, the sediment will gather along the bottom of the pond to the center of the pond. The centrifugal effect of the inner circulation of the breeding pond will make the sediment gather in the center of the bottom of the shrimp pond 2.

Abstract

The invention provides a highly-efficient sewage collecting and discharging device for a prawn culture pond. The highly-efficient sewage collecting and discharging device comprises a prawn pond, a sieve cover, a filter layer and a sewage discharge pipe, wherein the sieve cover is connected with the filter layer which is provided with a water isolation wall; the bottom part of the filter layer is provided with a rubber plate which is arranged on the surface of the bottom of the prawn pond; the filter layer is connected with the sewage discharge pipe through a sewage outlet; and the rubber plate is composed of the following components in parts by weight: 80 to 100 parts of chloroprene rubber, 1.5 to 3 parts of stearic acid, 3 to 6 parts of resin, 1 to 2 parts of a processing auxiliary agent, 15 to 30 parts of semi-reinforced carbon black, 30 to 45 parts of pyrolysis carbon black, 20 to 40 parts of talcum powder, 8 to 15 parts of vacuum cut 3 oil, 15 to 25 parts of lead oxide, 0.5 to 2 parts of an accelerator DM, 3 to 5 parts of solanesol and 0.01 to 0.04 part of sodium dichloroisocyanurate. The device provided by the invention has corrosion resistance and aging resistance, can centrally treat precipitates, avoids pollution to the environmental, can realize automatic sewage collecting and discharging, and has excellent effect.

Description

technical field [0001] The invention belongs to the technical field of cultivation, and in particular relates to a sewage collection and discharge device for a prawn cultivation pond. Background technique [0002] Shrimp farming has made an important contribution to the economic development of my country's marine fishery. In recent years, my country's shrimp aquaculture industry has developed rapidly, and its aquaculture area and output rank among the top in the world. While making achievements, the pollution of the shrimp farming industry itself is becoming more and more serious. These pollutions come from the residual bait and the metabolites of prawns. According to the traditional aquaculture equipment system, the polluted water in the aquaculture pond is directly discharged into the nearby sea area, which will inevitably affect the safety of the water body in the long run. Pollution of the local sea area, destruction of the coastal ecological balance, leading to the pr...
