Description

Technical Field

[0001] The present application relates to the technical field of fish-vegetable symbiosis, and in particular, to a fish excrement separation device and a fish-vegetable symbiosis system. Background Art

[0002] With the popularization of agricultural Internet of Things technology and the combination of pure organic farming and planting at this stage, more and more capital is pouring into the field of indoor planting and breeding with relatively high food safety, such as fish-vegetable symbiosis. Fish-vegetable symbiosis is a new type of compound farming system. It combines aquaculture and vegetable production, two originally completely different farming technologies, through ingenious ecological design to achieve scientific synergy and symbiosis, thereby achieving the ecological symbiosis effect of raising fish without changing water and worrying about water quality, and growing vegetables without fertilizing and growing normally. Achieving a harmonious ecological balance between animals, plants, and microorganisms is a sustainable, circular, zero-emission, low-carbon production model in the future, and it is also the most effective way to effectively solve the agricultural ecological crisis.

[0003] Vertical flow separators are commonly used in aquaculture to perform preliminary separation of aquaculture wastewater. Their working principle is to use the difference in gravity and buoyancy of particles such as fish feces to achieve separation. However, under the condition of continuous water inflow and outflow, when the gravity and buoyancy of the particles are close and the impact force of the water flow is large, some large particles of fish feces will be discharged with the water flow and cannot settle to the bottom, resulting in insufficient separation of particles and affecting the subsequent water treatment effect.

[0042] A sedimentation cavity is formed between adjacent partitions 520 and / or between the partitions 520 and the end wall of the fish excrement separation box 510 for sedimentation and separation of fish excrement.

[0043] Among them, the fish manure separation box 510 is preferably a rectangular structure with an inner cavity; and is preferably configured as an openable and closable box body, specifically, the fish manure separation box 510 includes a box body and a box cover 512, and the box cover 512 and the box body are detachably fixedly connected to facilitate observation of the internal conditions of the fish manure separation box 510, and when blockage or other conditions occur inside the box body, timely processing can be carried out.

[0044] Each partition 520 is arranged in the inner cavity of the fish manure separation box 510 along the longitudinal direction, where the longitudinal direction is the length direction of the rectangular structure. The water inlet and the drain are respectively located on the end walls at both ends of the longitudinal direction of the fish manure separation box 510. Preferably, the water inlet and the drain are at the same height, and the height of any partition 520 is lower than the height of the water inlet and the drain, so that the water flow flows upward, reducing the disturbance of the particles at the bottom of the sedimentation chamber, and facilitating the sedimentation of particles such as fish manure; preferably, the heights of the partitions 520 are set to be the same to facilitate production and processing.

[0045] In this embodiment, sedimentation chambers are formed between adjacent partitions 520 and between the partitions 520 and the longitudinal end walls of the fish excrement separation box 510 to perform graded sedimentation separation on the fish excrement.

[0046] Compared with the prior art, the fish excrement separation device 500 and the fish-vegetable symbiosis system provided in the embodiment of the present application have the following technical effects:

[0047] Several partitions 520 are arranged in the inner cavity of the fish excrement separation box 510 along the longitudinal direction, and a sedimentation chamber is formed between adjacent partitions 520 and between the partitions 520 and the end wall of the fish excrement separation box 510. The water inlet and the drain are respectively located at the longitudinal ends of the fish excrement separation chamber.

[0048] In order to further improve the sedimentation effect, the above device also includes:

[0049] The barrier 530 is longitudinally located in the first sedimentation chamber near the water inlet and is arranged opposite to the water inlet; the barrier 530 is fixedly connected to the fish excrement separation box 510; the water entering from the water inlet reduces the flow rate through the barrier 530 to facilitate the sedimentation of particles, and the cross section of the barrier 530 is circular or arc-shaped and can be set as needed. The barrier 530 is detachably fixedly connected to the bottom wall of the fish excrement separation box 510, such as by threaded fasteners, to facilitate disassembly and cleaning.

[0050] Specifically, a sewage outlet 511 is provided on the bottom wall of the fish manure separation box 510 corresponding to any sedimentation chamber, which is used to discharge the settled fish manure and realize the separation of large particles and water. Furthermore, the sewage outlet 511 is longitudinally located at one end of the sedimentation chamber close to the drain outlet, so that the sewage outlet 511 is arranged in the direction of water flow, so as to facilitate the collection and discharge of fish manure particles in each sedimentation chamber, and at the same time reduce the disturbance of the water flow rate to the particles as much as possible.

[0051] At the same time, the sewage outlet 511 is connected to a sewage pipeline 540, and the sewage pipeline 540 includes a plurality of sewage branch pipes 541 and a sewage main pipe 542. The sewage branch pipes 541 are located below the fish manure separation box 510 and extend in the transverse direction. The sewage branch pipes 541 are arranged in a one-to-one correspondence with the sewage outlet 511. One end of any sewage branch pipe 541 is connected to the sewage outlet 511, and the other end is connected to the sewage main pipe 542. The sewage main pipe 542 extends in the longitudinal direction of the fish manure separation box 510; a sewage control valve 543 is provided on the sewage main pipe 542 to control the on-off of the sewage main pipe 542, so as to perform interval sewage discharge on the fish manure separation box 510 and discharge particulate matter to the fermentation unit.

[0052] In this embodiment, the opposite side walls of the fish excrement separation box 510 are respectively provided with plug-in grooves, and the two lateral ends of any partition 520 are respectively plugged and fixed with the corresponding plug-in grooves. The plug-in grooves extend from top to bottom on the side walls until they contact the bottom wall of the fish excrement separation box 510; the plug-in grooves are arranged on the opposite side walls at the two lateral ends of the fish excrement separation box 510, and the two lateral ends of the partition 520 are respectively plugged and fixed with the corresponding plug-in grooves, so as to facilitate the disassembly and cleaning of the plug-in plates. In another embodiment, the plug-in grooves extend from top to bottom on the side walls until a 5-10 cm interval is reserved with the bottom wall of the fish excrement separation box 510.

[0055] On the basis of the above embodiments, the cross-section of the fish feces separation box 510 is a trapezoid, and the fish feces separation box 510 is inverted, so that the upper bottom of the trapezoid is at the bottom and the lower bottom is at the top, thereby forming a funnel-like structure, which is convenient for the deposition of particles such as fish feces at the bottom, and further improves the separation effect.

[0056] The specific working process is as follows: the aquaculture wastewater containing fish feces and residual bait enters the fish feces separation box 510 through the water inlet pipe 550, and the aquaculture wastewater is slowed down by the Karman vortex effect through the blocking member 530, and the particles in the aquaculture wastewater are partially settled; in the longitudinal flow process, it passes through the multiple partitions 520 again, and the particles in the aquaculture wastewater are gradually settled. Finally, the relatively clear liquid of the aquaculture wastewater is discharged from the drainage pipe 560 and enters the lower unit. When the water inlet control valve 551 is closed, the sewage control valve 543 is opened to discharge the particles through the sewage pipe 540 to the fermentation unit for treatment.
