Description

Technical Field

[0001] The utility model relates to the technical field of fishery breeding, and more specifically to a water-saving circulation device for fishery breeding. Background Art

[0002] The aquaculture density of modern fisheries is several times that of natural waters, and the species in the water bodies are single, which makes it impossible to form an ecological circulation system to absorb the metabolites and feed residues of aquatic products. It is necessary to remove the sewage and sediments at the bottom of the pool (pond) from time to time, and add some clean water. Usually, the sewage and sediments at the bottom of the pool (pond) are directly discharged into the sewage pipe network, resulting in a large waste of water resources; the supplementary water source is directly injected into the pool (pond), and the water quality and water temperature are uncontrollable, which has an adverse effect on the aquatic products. In order to recycle water resources as much as possible while discharging sewage, and to ensure that the water added to the pool (pond) meets the aquaculture requirements, a new type of water-saving circulation device is needed. Utility Model Content

[0027] See also Figure 1 , and combined with Figure 2 As shown, a water-saving circulation device for fishery breeding of the utility model comprises a sedimentation tank 2 and a backwashing pump 41 installed in the sedimentation tank 2 .

[0028] The sedimentation tank 2 has two parallel partitions 20 arranged at intervals, which divide the sedimentation tank 2 into a primary sedimentation tank 21, a secondary sedimentation tank 22 and a circulation tank 23. The bottom cross-sections of the primary sedimentation tank 21, the secondary sedimentation tank 22 and the circulation tank 23 are all conical, and concave pit bodies 10 are respectively arranged at the center positions of the primary sedimentation tank 21, the secondary sedimentation tank 22 and the circulation tank 23. The pit bodies 10 at the center positions of the primary sedimentation tank 21 and the secondary sedimentation tank 22 can collect precipitated dirt; the bottom pit body 10 of the circulation tank 23 is convenient for collecting the sewage after precipitation and filtration for recycling. For the specific structure, please refer to Figure 3 , Figure 4 and Figure 5 shown.

[0029] The backwash pump 41 is installed in the secondary sedimentation tank 22. A U-shaped backwash main pipe 42 is provided in the primary sedimentation tank 21. Nozzles 43 are provided on the inner sides of both ends of the backwash main pipe 42. The precipitated sewage (water) can be pressurized by the backwash pump 41 and then flushed to the bottom of the primary sedimentation tank 21 through the backwash main pipe 42 and the nozzle 43 to re-precipitate and recycle water resources. At the same time, the sewage that has settled on the bottom of the tank but has not entered the pit body of the secondary sedimentation tank 22 flows into the pit body 10, thereby reducing the frequency of manual dredging.

[0030] A connecting pipe 26 is provided on the partition 20 between the secondary sedimentation tank 22 and the circulation tank 23 . A filter cap 25 is installed on the connecting pipe 26 and the secondary sedimentation tank 22 . A check valve 27 is provided on the connecting pipe 26 and the circulation tank 23 .

[0031] A circulation pump 51 is installed in the circulation pool 23 and is connected to an external circulation water pipe 52 to the culture pool, so that the supernatant liquid after the sewage is precipitated and the supplementary water can be transported to the pool (pond).

[0032] Preferably, a control pipe with a manual butterfly valve 28 is also installed on the partition 20 between the secondary sedimentation tank 22 and the circulation tank 23, and the control pipe is at 1 / 2 height of the partition 20. A filter overflow port 24 is provided on the partition 20 between the primary sedimentation tank 21 and the secondary sedimentation tank 22, and a stainless steel filter screen is provided on the filter overflow port 24.

[0033] The stainless steel filter screens at both ends of the filter overflow port 24 can not only allow the initially precipitated sewage to overflow into the secondary sedimentation tank 22, but also filter the floating and suspended matter in the sewage. The connecting pipe 26 is installed on both sides of the partition 20 between the secondary sedimentation tank 22 and the circulation tank 23, the filter cap 25 is installed on the connecting pipe 26 on the side of the secondary sedimentation tank 22, and the check valve 27 is installed on the connecting pipe 26 on the side of the circulation tank 23. The specific structure is as follows: Figure 6 shown.

[0034] The filter cap 25 is a stainless steel mesh structure, which can not only allow the upper clear liquid after the secondary sedimentation of sewage to enter the circulation pool 23, but also filter the floating objects and suspended matter in the sewage. The installation depth of the manual butterfly valve 28 is located in the middle of the circulation pool 23. When it is closed, the secondary sedimentation tank 22 can store water to ensure the effect of secondary sedimentation; when the secondary sedimentation tank 22 is not full, the manual butterfly valve 28 is opened, and the upper clear liquid of the secondary sedimentation tank 22 can enter the circulation pool 23. Preferably, the operating lever of the manual butterfly valve 28 is located above the pool surface for easy operation. The check valve 27 is installed on the upper part of the partition 20. When the secondary sedimentation tank 22 is full of water, it can overflow into the circulation pool 23 through the filter cap 25, the connecting pipe 26 and the check valve 27 to prevent the primary sedimentation tank 21 and the secondary sedimentation tank 22 from overflowing; when the supplementary water is injected into the circulation pool 23, even if the water level of the circulation pool 23 is higher than that of the secondary sedimentation tank 22, the supplementary water will not flow back into the secondary sedimentation tank 22.

[0035] The primary sedimentation tank 21 of the utility model is equipped with a sewage pipe 32, which is connected to a sewage pump 31 installed in the primary sedimentation tank 21, and a water supply pipe 6 connected to an external water supply tank is installed on the circulation tank 23. After the upper clear liquid or supplementary water after sewage sedimentation enters the circulation tank 23, the water quality and water temperature can be adjusted according to the breeding requirements, and then transported to the pool (pond) after meeting the requirements.

[0036] The utility model discloses a water-saving circulation device for fishery breeding. A partition 20 is arranged in the middle of a sedimentation tank to divide the sedimentation tank into a primary sedimentation tank 21, a secondary sedimentation tank 22 and a circulation tank 23. Filter overflow ports 24 are arranged on both sides of the top of the partition 20 between the primary sedimentation tank 21 and the secondary sedimentation tank 22. A filter cap 25, a connecting pipe 26, a check valve 27 and a manual butterfly valve 28 are arranged on the partition 20 between the secondary sedimentation tank 22 and the circulation tank 23. The bottoms of the primary sedimentation tank 21, the secondary sedimentation tank 22 and the circulation tank 23 are all "concave" structures with high sides and low middle. The grooves at the bottoms of the primary sedimentation tank 21 and the secondary sedimentation tank 22 are sewage pits for collecting precipitated dirt. The groove at the bottom of the circulation tank 23 is a water accumulation pit for collecting the sewage after precipitation and filtration for recycling.

[0037] Finally, the method of this application is only a preferred implementation scheme and is not intended to limit the protection scope of the utility model. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model should be included in the protection scope of the utility model.
