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. 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. Large particles will settle and stack when they enter the plant planting bed. Over time, they will easily rot and stink and produce harmful substances, and affect the decomposition of fish feces by microorganisms. Utility Model Content

[0047] In a specific embodiment, the fish feces separation device 500 provided in the present application can be applied to a fish-vegetable symbiotic system or an aquaculture system, and includes:

[0048] The fish excrement separation box 510 has an inner cavity, and a plurality of partitions 520 are arranged in the inner cavity of the fish excrement separation box 510 along the longitudinal direction. The end walls at both ends of the fish excrement separation box 510 are respectively provided with a water inlet and a water outlet;

[0049] 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; a sewage outlet 511 is provided on the bottom wall of the fish excrement separation box 510 corresponding to the sedimentation cavity for discharging the settled fish excrement;

[0050] The fish excrement cutting assembly 530 is arranged opposite to the water inlet and is used for cutting fish excrement.

[0051] 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.

[0052] 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.

[0053] 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.

[0054] Among them, the fish manure cutting component 530 is arranged opposite to the water inlet to cut and break the fish manure entering the fish manure separation box 510, so that the large particles are converted into small particles to prevent them from clogging the sewage outlet 511, and can be smoothly discharged to the next treatment unit; at the same time, the sewage containing small particles is discharged through the drainage outlet to the ecological planting bed for biological decomposition, and the small particles contained therein can provide sufficient nutrients for the plants, which can be used by the plants and the organisms in the ecological planting bed, thereby improving the utilization rate of waste.

[0055] In a specific embodiment, the fish feces cutting assembly 530 is longitudinally located in the first sedimentation chamber near the water inlet; the fish feces cutting assembly 530 is detachably fixedly connected to the fish feces separation box 510, thereby facilitating disassembly and assembly; the height of the fish feces cutting assembly 530 can be set according to the height of the water inlet, and preferably the two are at the same height plane to increase the contact area between the fish feces cutting assembly 530 and the water flow and improve the cutting effect.

[0056] Specifically, the fish excrement cutting assembly 530 includes a mounting shaft 531 and a cutting piece; the mounting shaft 531 is fixed to the bottom wall of the fish excrement separation box 510, and preferably adopts a detachable fixed connection to facilitate disassembly and assembly; the cutting piece is fixed to the mounting shaft 531 and can rotate around the mounting shaft 531, and the axis of the cutting piece is preferably colinear with the axis of the mounting shaft 531. The cutting piece rotates around the mounting shaft 531 under the action of the water flow at the water inlet to cut the fish excrement; the cutting piece is fixed to the mounting shaft 531 through a bearing, and there is no need to set up additional power equipment to provide power for the rotation of the cutting piece, which simplifies the device structure and converts the kinetic energy and potential energy of the water into the kinetic energy of the cutting piece.

[0057] The cutting member includes a turbine blade 533 and a rotary cutting blade 532. The turbine blade 533 is detachably fixedly connected to the mounting shaft 531 and rotates around its own axis under the drive of the water flow to achieve the cutting of large particles such as fish feces. The turbine blade 533 is a mature existing technology, and its specific structure is not repeated. The rotary cutting blade 532 can be arranged in a radial or spiral shape to increase the contact area.

[0058] Furthermore, in order to improve the cutting effect, a rotary cutting blade 532 is provided on the upper and lower sides of the turbine blade 533, respectively, so that the water flow from top to bottom is cut in sequence through the three vertical cutting structures, and the crushing effect is improved through the combined cutting method of the three cutting structures.

[0059] Compared with the prior art, the fish feces separation device 500 provided in the embodiment of the present application has the following technical effects:

[0060] First, a fish excrement cutting assembly 530 is arranged at a position relative to the water inlet of the fish excrement separation box 510 to cut the fish excrement entering the fish excrement separation box 510, so as to preliminarily cut and process the large particles of fish excrement to prevent them from adhering to the bottom of the box due to gravity to form dust and dirt, making it impossible to discharge sewage, and preventing the sewage discharge pipeline 540 from being blocked;

[0061] Second, the large particles such as fish feces are cut into small particles by the fish feces cutting assembly 530, and are directly discharged into the planting equipment through the drainage port. The small particles are biodegraded by the planting equipment to ensure the nutrient requirements of the plants in the planting equipment;

[0062] Third, a plurality of partitions 520 are arranged longitudinally in the inner cavity of the fish manure separation box 510, and a sedimentation chamber is formed between adjacent partitions 520 and between the partitions 520 and the end walls of the fish manure separation box 510. The water inlet and the drain are respectively located at the longitudinal ends of the fish manure separation chamber. The aquaculture sewage enters the box through the water inlet, and after being acted upon by a plurality of partitions 520, the particles in the sewage are gradually settled, and the clearer sewage is discharged to the lower-level treatment equipment through the drain. The above device is provided with a horizontal multi-stage sedimentation device to effectively settle and separate large particles such as fish manure.

[0063] Specifically, the bottom wall of the fish manure separation box 510 corresponding to any sedimentation chamber is provided with a sewage outlet 511 for discharging the settled fish manure to achieve 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 accordance with the direction of water flow, so as to facilitate the collection and discharge of fish manure particles in each sedimentation chamber, while minimizing the disturbance of the water flow rate on the particles.

[0064] 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 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.

[0065] 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.

The drain pipeline 560 is connected to the drain outlet, and the drain pipeline 560 has a drain control valve. Preferably, the water inlet control valve 551, the drain control valve and the sewage control valve can be set as solenoid valves for automatic control.

[0067] The drainage pipeline 560 may include a plurality of drainage branches, which are arranged according to the structure of the ecological planting bed to facilitate uniform irrigation of the ecological planting bed.

[0068] 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.

[0069] 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 is cut by the fish feces cutting assembly 530, and the large particles such as fish feces are crushed into small particles; in the process of longitudinal flow, the particles in the aquaculture wastewater are gradually settled through the action of multiple partitions 520, and 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 is opened to discharge the particles through the sewage pipe 540 to the fermentation unit for treatment.
