Description

TECHNICAL FIELD

[0001] The present application relates to fish water circulation filtering technology in fish-vegetable symbiotic system, and particularly relates to a fish-vegetable symbiotic water filtering device. BACKGROUND

[0002] Fish-vegetable symbiosis is a new type of complex farming system, which combines aquaculture and crop cultivation. By simulating the recycling mode of the ecological system, the sediment and fecal excretion produced in aquaculture are separated to make fertilizer for crop cultivation, and the water in aquaculture is used for crop irrigation and aquaculture after filtration.

[0003] In the existing fish-vegetable symbiotic system, the breeding density of the aquaculture tank is large, which will produce a large amount of sediment and fecal excretion in a short time, so it is necessary to quickly separate the sediment and fecal excretion in the aquaculture tank, resulting in a large amount of water change in the aquaculture tank.

[0004] And the existing fish-vegetable symbiotic water filtering device is filtered by multiple layers of filter material, and the efficiency of separation and filtration of the multiple layers of filter material is low and easy to block. The low water filtration efficiency cannot be backflowed in time, which requires a larger area of water storage space, and the easy blockage requires frequent cleaning of the filter material.

[0007] Optionally, the bottom of the box body is in communication with the irrigation pipe through a fertilizer water pipe, and a valve is installed on each of the irrigation pipe and the fertilizer water pipe.

[0008] Optionally, a filter layer is fixed at the upper end of the water bin in the box body, and a filter screen is arranged at the upper end of the filter layer.

[0019] In order to make the purpose, technical solutions and advantages of the embodiments of the application more clear, the technical solutions in the embodiments of the application will be described clearly and completely. Obviously, the described embodiments are some embodiments of the application, but not all the embodiments. Based on the embodiments in the application, all other embodiments obtained by those skilled in the art without creative labor also belong to the protection scope of the application.

[0020] As​​​Figures 1-4 As shown, the embodiment of the present application provides a fish and vegetable symbiotic water filtering device, which comprises a box 1, a partition plate 2 vertically fixed in the box 1 to separate the box 1 into a water bin and a fertilizer bin. A plurality of cyclones 3 are vertically fixed on the top of the box 1, the water inlet pipe 4 at the side end of the cyclone 3 is communicated with the breeding tank, the water outlet pipe 5 at the top of the cyclone 3 is communicated with the upper end of the water bin, and the discharge port at the bottom of the cyclone 3 is communicated with the upper end of the fertilizer bin. The box 1 is provided with a water outlet pipe 9 at the bottom of the water bin, the water outlet pipe 9 is respectively communicated with a backflow pipe 10 and an irrigation pipe 11, and the backflow pipe 10 and the irrigation pipe 11 are respectively provided with valves.

[0021] In use, the water in the breeding tank is discharged into the cyclone 3 through the water inlet pipe 4, and the two-phase separation of different specific gravities occurs after the cyclone is generated in the cyclone 3. The water and the feces and sundries of the aquatic products with larger specific gravity are discharged from the discharge port at the bottom of the cyclone 3 to the fertilizer bin under the action of the centrifugal force, and the water with smaller specific gravity is overflowed upward and then discharged into the water bin through the water outlet pipe 5. The water in the water bin of the box 1 is discharged through the water outlet pipe 9, a part of which is backflowed to the breeding tank through the backflow pipe 10 to recycle and supplement the breeding tank, and the other part is flowed into the cultivated crops through the irrigation pipe 11 to irrigate the crops, and the flow rate and the proportion of the two are adjusted through the valves.

[0022] In the embodiment, the water for breeding aquatic products is continuously discharged into the cyclone 3 through the water inlet pipe 4 for separation and filtration, the cyclone 3 can quickly filter out most of the sediments and feces and excrement of the aquatic products in the breeding tank, and then the clean water is backflowed to the breeding tank through the box 1. The cyclone 3 has high separation and filtration efficiency and strong capacity, and is more suitable for intensive breeding and can maintain the water environment of aquatic breeding.

[0023] After the water for breeding aquatic products is separated and filtered, the water can be reasonably distributed through the box 1, so that the appropriate amount of water flows into the cultivated crops through the irrigation pipe 11 to irrigate the crops.

[0024] In a possible implementation, the box 1 is communicated with the irrigation pipe 11 through the fertilizer water pipe 12 at the bottom of the fertilizer bin, and the irrigation pipe 11 and the fertilizer water pipe 12 are respectively provided with valves.

[0025] In the process of flowing into the crops through the irrigation pipe 11, the feces and excrement of the aquatic products can be appropriately added into the irrigation pipe 11 through the fertilizer water pipe 12. The feces and excrement of the aquatic products are used as fertilizer and irrigated into the crops with water, and the fertilization and water supplement are completed at the same time.

[0026] In a possible implementation, the upper end of the water bin in the box 1 is fixed with a filter layer 6, and the upper end of the filter layer 6 is provided with a filter screen 7.

[0027] The filter layer 6 and the filter screen 7 can further filter out the floating objects in the water. The nitrifying bacteria in the filter layer 6 can decompose the chlorine gas generated by the fecal excretion in the water. Since the cyclone 3 at the front end separates most of the sediment and fecal excretion, the filter layer 6 and the filter screen 7 will not be subjected to excessive filtering pressure.

[0028] In a possible implementation, the side end of the box 1 is provided with an opening 8 for opening and cleaning the filter layer 6 and the filter screen 7.

[0029] The opening 8 can be opened to take out the filter layer 6 and the filter screen 7, and the filter layer 6 and the filter screen 7 can be cleaned or replaced.

[0030] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, and are not limited thereto; although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand; it can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacement for part or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application.
