Abstract
Description
Technical Field
[0001] This utility model belongs to the field of shrimp farming technology, specifically referring to a shrimp pond for industrialized shrimp farming. Background Technology
[0002] The development of shrimp farming in my country is closely related to market demand. With increasing market demand, shrimp farming has developed rapidly, especially large-scale factory farming. In factory-style recirculating aquaculture, shrimp ponds, as containers for shrimp farming, are extremely important. Generally, shrimp ponds are constructed as square pools, with aeration devices installed at the bottom. Because shrimp farming requires high dissolved oxygen, the bottom of the pond is usually covered with aeration devices to provide oxygen, resulting in high construction costs and high energy consumption due to the large aeration volume. Furthermore, existing shrimp ponds have shortcomings such as poor insulation due to the simple concrete walls, stagnant water, and the tendency for shrimp shells and excrement to accumulate in corners and be difficult to clean. Therefore, it is necessary to optimize the structure of existing industrialized shrimp farming ponds. Utility Model Content
[0003] This invention provides a shrimp pond for industrial shrimp farming, aiming to overcome the aforementioned shortcomings in the existing technology.
[0004] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A shrimp pond for industrialized shrimp farming includes a shrimp pond body and an aeration system. The bottom wall of the shrimp pond body is set as a slope that gradually slopes down from the periphery to the center and a drain outlet is provided at the center. The drain outlet is connected to an external discharge pipe. The periphery wall of the shrimp pond body is composed of marine modules filled with concrete, and the included angle between adjacent walls is an obtuse angle. The aeration system includes an aeration fan, a connecting pipe, and nano aerators. Multiple sets of nano aerators are arranged circumferentially at intervals on the bottom wall of the shrimp pond body near the periphery wall. The aeration fan is connected to each nano aerator through the connecting pipe. An aeration regulating valve is provided on the connecting pipe. The aeration spray direction of each nano aerator is deviated from the vertical direction to jointly promote the circulation of the farming water in the shrimp pond body.
[0005] Based on the above technical solution, the present invention can be further improved as follows.
[0006] Furthermore, the bottom wall of the shrimp pond has a slope of 5%-20%.
[0007] Furthermore, all the surrounding walls of the shrimp pond form an octagonal structure, with the included angle between two adjacent walls being between 120 and 150°.
[0008] Furthermore, the shrimp pond body is equipped with multiple nano-aerators surrounding the drain outlet near the drain outlet.
[0009] The advantage of the above-mentioned further improvements is that a ring of nano aerators is installed around the bottom of the pool near the drain outlet, which can directly aerate and oxygenate the water in the center of the pool. When working together with a ring of nano aerators near the wall, the aeration and oxygenation range is larger and the efficiency is higher. At the same time, the bubbles generated by the aerators have a certain isolation effect, which can effectively prevent shrimp from getting close to the drain outlet, so as to prevent shrimp from being pulled out along with shrimp shells and shrimp feces when they are being pumped out.
[0010] Furthermore, the angle between the aeration spray direction of the nano aerator and the vertical direction is 10-30°.
[0011] Furthermore, the connecting pipe is a flexible tube made of PU or PA material.
[0012] Furthermore, there are four sets of nano aerators near the surrounding walls, and adjacent sets of nano aerators are arranged at 90° intervals in the circumferential direction of the shrimp pond body.
[0013] Furthermore, each group of nano-aerators is independently connected to the aeration blower and the aeration volume is controlled by an independently set aeration regulating valve.
[0014] Compared with the prior art, the beneficial effects of this utility model are:
[0015] The shrimp pond for industrial shrimp farming provided by this utility model has an angle greater than 90 degrees (obtuse angle) between adjacent walls on one side of the pond, eliminating dead corners. Simultaneously, the aeration spray direction of each nano-aerator connected to the aeration fan deviates from the vertical direction, forming an angle. The obliquely sprayed airflow works together to circulate the water in the shrimp pond, resulting in higher aeration and oxygenation efficiency and reduced energy consumption. Furthermore, because there are no dead corners at the junctions of adjacent walls, the flowing water effectively carries away shrimp shells and feces from the corners, preventing accumulation. The pond bottom slopes from the wall sides towards the drain outlet at the center. The flowing water automatically collects shrimp shells and feces towards the drain outlet, which is then periodically discharged, resulting in a cleaner pond. The main walls of the shrimp pond are constructed of cast concrete marine modules, which are both sturdy and durable, and also provide insulation, promoting shrimp growth. Attached Figure Description

[0020] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.
[0021] In the description of this utility model, if terms such as "upper", "lower", "left", "right", "top", "bottom", "inner", and "outer" are used to indicate the orientation or positional relationship, the orientation or positional relationship indicated is based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
[0022] like Figure 1 and 2 As shown, this utility model provides a shrimp pond for industrial shrimp farming, which includes a shrimp pond body 1 and an aeration system. The bottom wall 2 of the shrimp pond body 1 is set as a slope that gradually slopes down from the periphery to the center and has a drain outlet 3 at the center. The drain outlet 3 is connected to an external discharge pipe. The periphery wall 4 of the shrimp pond body 1 is composed of concrete-filled marine modules 5, and the included angle between adjacent walls 4 is an obtuse angle. The aeration system includes an aeration blower 6, a connecting pipe 7, and nano aerators 8. Multiple sets of nano aerators 8 are arranged circumferentially at intervals on the bottom wall 2 of the shrimp pond body 1 near the periphery wall 4. The aeration blower 6 is connected to each nano aerator 8 through the connecting pipe 7. An aeration regulating valve 9 is provided on the connecting pipe 7. The aeration spray direction of each nano aerator 8 is deviated from the vertical direction to jointly promote the circulation of the farming water in the shrimp pond body 1.
[0023] It should be noted that the walls are constructed using marine-grade modules, then poured and waterproofed both internally and externally. A drain outlet is located at the lowest point of the bottom center of the shrimp pond, and the bottom of the pond has a slight slope, sloping from the walls towards the drain outlet. The aeration system is used to aerate the water within the shrimp pond. Each nano-aerator is placed on the bottom wall and submerged in the water. Air output from the aeration blower enters the nano-aerators through connecting pipes for dispersion, increasing dissolved oxygen in the aeration water. The aeration regulating valve can be adjusted between fully open and fully closed to control the aeration rate. The air dispersed by the nano-aerators promotes a slight flow of water within the shrimp pond, which is beneficial for oxygen supply, improves the utilization rate of the aeration device, saves more than 50% of the aeration volume, and conserves significant energy. It also helps shrimp shells and excrement in the aeration water to collect and be discharged from the central drain outlet.
[0024] In one embodiment of this utility model, the bottom wall 2 of the shrimp pond body 1 has an inclination slope of 5%-20%, and all the surrounding walls 4 of the shrimp pond body 1 together form an octagonal structure, with the included angle between two adjacent walls 4 being between 120-150°.
[0025] It should be noted that, as Figure 1 and 2 As shown in the figure, the bottom wall of the shrimp pond has a slope and the main body of the shrimp pond is octagonal when viewed from above. The included angle between two adjacent walls is about 145 degrees (the angle on one side of the pond). The included angle inside the walls is greater than 90 degrees. The water for aquaculture flows and will not form dead corners, causing shrimp shells and shrimp feces to accumulate.
[0026] In one embodiment of this utility model, such as Figure 1 As shown, the shrimp pond body 1 has multiple nano-aerators 8 arranged around the drain outlet 3 near the drain outlet 3.
[0027] It should be noted that, as Figure 1 As shown, there are four nano-aerators around the drain outlet, with adjacent pairs spaced 90° apart in the circumferential direction. These four nano-aerators can be connected by a ring-shaped air duct.
[0028] In one embodiment of this utility model, the angle between the aeration spray direction of the nano aerator 8 and the vertical direction is 10-30°.
[0029] In one embodiment of this utility model, the connecting pipe 7 is a flexible tube made of PU or PA material.
[0030] In one embodiment of this utility model, four sets of nano aerators 8 are provided near the surrounding wall 4, and adjacent sets of nano aerators 8 are arranged at 90-degree intervals in the circumferential direction of the shrimp pond body 1.
[0031] In one embodiment of this utility model, each group of nano aerators 8 is independently connected to the aeration blower 6 and the aeration volume is controlled by the independently set aeration regulating valve 9.
[0032] Using the features provided by this utility model Figure 1 When shrimp are raised in the industrialized shrimp ponds shown, actual testing and comparison have shown that the dissolved oxygen levels in the water at all points in the shrimp ponds of this invention can fully meet the dissolved oxygen requirements for shrimp farming. Compared to traditional shrimp ponds where the bottom of the pond is covered with aeration devices, this invention can ensure oxygen supply to the entire pond with only a few aeration devices. The installation cost is lower, and the aeration volume of the blowers used is far lower than that required for covering the bottom of the pond with aeration devices (approximately 50% less), resulting in a significant reduction in energy consumption.
[0033] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
