Problems solved by technology

The culture ponds of this mode are generally built according to the height difference of the terrain, and are constructed in series and parallel arrangement by utilizing the natural drop of water. Most of the bait residue and other debris settle to the bottom of the pond, and a small amount flows to the next-level pond with the water flow, and the same deposition occurs in the next-level breeding pond, making the water quality of the first-level pond inferior to the first-level

Embodiment 1

[0026] Such as Figure 1-4Shown, the scheme that the present invention takes for realizing above-mentioned object is: a kind of prawn culture water source sedimentation tank, comprises sedimentation tank 5, and the top of sedimentation tank 5 sides is provided with the 4th water inlet 411 and secondary sedimentation tank 4 is communicated with, secondary The sedimentation tank 4 communicates with the first-level disinfection tank 2 and the second-level disinfection tank 3 through the third water inlet 311 provided above, and the first-level disinfection tank 2 and the second-level disinfection tank 3 are connected to the upper end of the reservoir 1 through the second water inlet 211 Connected, the reservoir 1 communicates with the culture pond 6 through the water inlet pipe 111, the inside of the reservoir 1 is provided with a coaxial water pipe 24, the upper end of the water pipe 24 is vertically connected with the water inlet pipe 111 through the bearing 25 built in the pipe...

Embodiment 2

[0032] Such as Figure 5-8 As shown, the optimization scheme of this embodiment on the basis of Embodiment 1 is: an upper funnel 20 is provided in the reservoir 1, the lower end of the upper funnel 20 communicates with the upper end of the lower funnel 21 through a ring 19, and the upper end of the upper funnel 20 The bottom surface and the bottom surface of the lower funnel 21 are connected to the inner wall of the reservoir 1, the second water inlet 211 is arranged on the upper edge of the upper funnel 20, the outer surface of the upper funnel 20 is provided with a heating plate 23, and the upper surface of the lower funnel 21 is provided with an arc Slot 22. By setting the upper funnel in the reservoir, the lower end of the upper funnel communicates with the upper end of the lower funnel through a ring, the upper bottom of the upper funnel and the lower bottom of the lower funnel are connected to the inner wall of the reservoir, and the second water inlet is attached to the...

Embodiment 3

[0036] The working principle of the water source sedimentation tank for prawn cultivation in the present invention is as follows: the external seawater is poured into the first-level sedimentation tank 5 through the seawater inlet 511, and after preliminary sedimentation, it enters the second-level sedimentation tank 4 through the fourth water inlet 411 and then settles again. , seawater enters the first-level disinfection pool 2 and the second-level disinfection pool 3 through the third water inlet 311 for disinfection, and the sterilized seawater enters the reservoir 1 through the second water inlet 211. The pump draws the water in the reservoir 1 into the culture pond 6 from the water inlet pipe 111 .

Abstract

The invention discloses a water source sedimentation tank for prawn cultivation, which comprises a sedimentation tank. A fourth water inlet is arranged on the upper side of the sedimentation tank to communicate with the secondary sedimentation tank. The pool is connected to the secondary disinfection pool, the primary disinfection pool and the secondary disinfection pool are connected to the upper end of the reservoir through the second water inlet, the reservoir is connected to the breeding pool through the water inlet pipe, and the interior of the reservoir is provided with a coaxial The upper end of the water pipe is vertically connected with the water inlet pipe through the built-in bearing of the pipe sleeve, and the lower end of the water pipe is connected with a rotary pump. By setting up multi-stage sedimentation tanks and disinfection tanks, seawater can be sedimented, purified, and disinfected multiple times. The device has a simple structure, is easy to operate, and has an ideal seawater purification effect, which is suitable for large-scale promotion.

Description

technical field [0001] The invention relates to the field of aquaculture, in particular to a water source sedimentation pond for shrimp cultivation. Background technique [0002] Water source is one of the key factors for the success of shrimp farming. It is an important step in the breeding process to carry out sedimentation and disinfection treatment on the water coming in from the outer sea. Therefore, a reasonable sedimentation tank needs to be designed. [0003] In order to improve the utilization rate of water resources and land resources, increase the output of prawns per unit area, and reduce labor costs, according to the living and growth habits of prawns, domestic prawn farming mostly adopts the intensive farming mode of running water. The culture ponds of this mode are generally built according to the height difference of the terrain, and are constructed in series and parallel arrangement by utilizing the natural drop of water. Most of the bait residue and othe...
