Problems solved by technology

This method wastes a lot of manpower and material resources, wastes a lot of water resources, the breeding density is low, and the risk is high, which is not conducive to the expansion of intensive farming scale.
Every breeding method needs to ensure that the concentration of dissolved oxygen in the water meets the growth requirements of fish and shrimp, especially high-density farming, once the lack

Example Embodiment

[0019] Example 1:

[0020] Such as figure 1 As shown, the recirculating water fishery multifunctional pool of the present invention includes a barrel-shaped pool body 1, in which a cone-shaped bucket 2 with a large top and a small bottom is arranged inside the pool body 1, and the pool body 1 is divided into an upper culture bin 3 and the lower inner bin 4; on the wall of the cone 2 is provided with a communication pipe 8 communicating with the inner bin 4 and close to the bottom of the inner bin 4, and at the bottom of the cone 2 is provided a dirt collection and sedimentation Bin 5, the sewage collection and sedimentation bin 5 is connected with a sewage pipe 7 extending to the outside of the tank body 1, and is fitted with a corresponding sewage valve 16; a circulating water pump 11 is provided outside the tank body 1, and the circulating water pump 11 The inlet pipe 12 communicates with the bottom of the inner bin 4, and the outlet pipe 13 communicates with the upper part of...

[0021] Example 2:

[0022] On the basis of the above-mentioned embodiments, in order to further implement the present invention better, a fine filter 9 is fitted on the top of the communicating pipe 8, and a corresponding coarse filter is fitted on the top of the dirt collection sedimentation bin 5 Filter 6. The fineness and coarseness of the fine filter screen 9 and the coarse filter screen 6 are in relative terms. The pore size of the fine filter screen 9 is relatively fine, mainly to filter dirt, aquatic product seedlings, etc., to avoid entering the inner warehouse 4 and reduce Cleaning frequency of inner chamber 4. The coarse filter screen 6 is mainly used to filter aquatic products and prevent the aquatic products from entering the sewage pipe 7 to be discharged or blocking the sewage pipe 7.

Example Embodiment

[0023] Example 3:

[0024] On the basis of the above-mentioned embodiments, in order to further implement the present invention better, a gas injection pipe 14 is provided on the upper part of the inner warehouse 4, and a corresponding gas injection pipe valve 15 is fitted. In use, when the inner chamber 4 and the breeding chamber 3 are filled with water, oxygen / air is injected into the inner chamber 4 through the gas injection pipe 14. The pressure of the oxygen / air will transfer the water in the inner chamber 4 to the breeding chamber 3 through the connecting pipe 8 In the middle row, to a certain extent, stop oxygen / air injection and close the gas injection pipe valve 15, so that an oxygen tank is formed in the inner tank 4. The oxygen in the oxygen tank is pressed into the water, which can supply oxygen to the water for a long time, which is not only beneficial to breeding, but also beneficial to the normal operation of the biological filler 10 in the inner tank 4, maintainin...

Abstract

The invention relates to a fishery breeding device, in particular to a water-circulated fishery multi-functional pond which can purify water quality and enable water to be circulated for use. A communicating pipe which communicates with an inner bin and is near the bottom of the inner bin is arranged on the hopper wall of a conical hopper, and a sewage collecting and precipitating bin is arrangedat the bottom of the conical hopper; a circulating water pump is arranged outside a pond body, a water inlet pipe of the circulating water pump communicates with the bottom of the inner bin, and a water outlet pipe communicates with the upper part of the pond body; and biological fillings are arranged in the inner bin. According to the water-circulated fishery multi-functional pond disclosed by the invention, in the breeding process, excrement and urine of aquatic products and feed residues slide downwards into the sewage collecting and precipitating bin along the conical hopper; besides, water in the inner bin is circulated into the pond body from the water outlet pipe by the circulating water pump, because the water outlet direction is tangent to the inner wall of the pond body, the water can be pushed to move to form a whirlpool, and sewage collection is convenient; and in addition, the biological fillings are also arranged in the inner bin and can achieve better purifying effects on the water quality, so that the circulated water quality is well maintained, and growth of the aquatic products is convenient.

Description

technical field [0001] The invention relates to a fishery cultivation device, in particular to a fishery multifunctional pool with circulating water capable of purifying water quality and circulating water. Background technique [0002] In fish farming, the main methods are pond culture, greenhouse culture and indoor factory culture, and the breeding density increases successively. Among them, indoor factory culture is the development trend. Its main characteristics are the realization of water quality control and high-density culture. It is a kind of Intelligent high-yield farming model. In the conventional pond and greenhouse breeding process, due to the large volume of the water body, it is difficult to collect and discharge the feces and feed residues of fish and shrimp. The continuous accumulation will pollute the water body and affect the water quality. Various methods must be used to adjust the water quality To meet the growth of fish and shrimp, the process is cumbe...
