Description

Technical Field

[0001] The utility model relates to the technical field of aquaculture, in particular to an automatic sewage discharge device for aquaculture. Background Art

[0002] Aquaculture is the breeding of aquatic animals and plants by humans using aquaculture techniques and facilities according to the ecological habits of the breeding objects and the requirements for the water environment conditions. Aquaculture is mostly carried out in breeding ponds or breeding boxes. During the breeding process, the breeding ponds will accumulate uneaten food residues, feces discharged by aquatic animals, and sludge and other bacteria-carrying wastes, which will seriously deteriorate the water environment in the breeding ponds and are not conducive to the survival of aquatic products. Therefore, in the process of aquaculture, it is very important to regularly treat the sewage in the breeding ponds.

[0003] Patent application number CN201921585377.2 is an aquaculture pond that is easy to discharge sewage. The rollers are arranged to roll outward on the upper surfaces of the left and right sides of the aquaculture pond body, so that the cleaning device moves outward, so that the brush layer on the cleaning device brushes the bottom surface of the aquaculture pond body, and then the sewage pipe is opened at the same time to discharge the sediment on the bottom surface of the aquaculture pond body, so that there is no need to drain all the water in the pond for sewage discharge. However, when the above scheme is used, the staff needs to manually operate the brush to clean the bottom of the pond, which is cumbersome and increases labor costs. In addition, during the use of the existing automatic sewage discharge device for aquaculture, the sewage outlet usually needs to be manually opened, which increases the workload of the operator, and is not convenient for purifying the discharged wastewater to achieve the purpose of recycling, which increases the aquaculture cost. In addition, after the water is changed, the oxygen content in different water areas in the pond is not balanced, which increases the aquaculture risk. Utility Model Content

When the head end of the air pipe 223 is positioned, the solenoid valve 222 is opened, thereby forming a siphon effect, and the wastewater is discharged through the drain pipe 221. When the water level in the breeding pond 1 drops to the position of the lowest point of the positioning air pipe 223, the head end of the positioning air pipe 223 is exposed from the water and exposed to the air.

[0024] refer to Figure 1 , Figure 2 and Figure 4As shown, the separator 32 includes a central tube 321 disposed inside the sedimentation barrel 31, and a second connecting tube 322 connected to one end of the first connecting tube 23; the separator 32 also includes a baffle 323 fixed to one end of the central tube 321, and an overflow trough 324 disposed on the top of the sedimentation barrel 31; the cleaning member 35 includes a motor 351 disposed at the bottom of the sedimentation barrel 31, a transmission rod 352 fixed to the output end of the motor 351, and a scraper 353 fixed to the outside of the transmission rod 352; by providing the central tube 321, it is convenient for the wastewater to enter the sedimentation barrel 31 through the second connecting tube 322 and then be removed from the upper The wastewater moves downward in a vertical flow, hitting the baffle 323 at the lower end of the central tube 321, slowing down the water flow. Large particles of feces and residual bait are dispersed and precipitated into the bottom of the cone at the bottom of the sedimentation barrel 31. The separated clean water flows out through the overflow trough 324 to achieve solid-liquid separation. The water is then further filtered through the filter screen 33, thereby improving the safety of the purified wastewater. The wastewater re-enters the breeding pond 1 through the water injection pipe 34 on the rear side of the filter screen 33, completing the cycle. The cleaning part 35 is provided to facilitate the cleaning of solids precipitated at the bottom of the cone of the sedimentation barrel 31, so that it will not block the sewage outlet 36, thereby improving the stability of the device during operation.

[0025] refer to Figure 1 , Figure 2 and Figure 3 As shown, the driving member 42 includes a rotating shaft 421 rotating inside the bearing base 41, and a paddle 422 and a cleaning plate 423 fixed to the outside of the rotating shaft 421; the oxygen supply member 44 includes a rotating joint 441 connected to the output end of the oxygen pump 43, and an oxygen supply pipe 442 connected to one end of the rotating joint 441; the oxygen supply member 44 also includes a shunt pipe 443 connected to the inside of the oxygen supply pipe 442, and an air stone 444 connected to one end of the shunt pipe 443; by providing the paddle 422, it is convenient for the water inside the culture pond 1 to form a siphon effect when it is discharged through the drain pipe 221, and a vortex is formed in the center of the culture pond 1, thereby driving the paddle 422 to rotate, and at the same time driving the rotating shaft 421 to rotate, and by providing the bearing The base 41 improves the stability of the rotating shaft 421 when it rotates. By setting the cleaning plate 423, it is convenient to remove the sediment at the bottom of the breeding pond 1. At the same time, the sediment is discharged into the pond with the water flow, realizing automatic cleaning and reducing the pollution of the sediment to the water quality. By setting the oxygen pump 43, it is convenient to supply oxygen to the water in the breeding pond 1. By setting the rotating joint 441, it is convenient for the oxygen supply pipe 442 to follow the rotation of the rotating shaft 421. By setting the oxygen supply pipe 442, it is convenient to supply oxygen to the diversion pipe 443. By setting the air stone 444, it is convenient to transport oxygen to the water. When the wastewater is discharged from the pool and the water is refilled, the oxygen supply component 44 rotates with the rotating shaft 421 to evenly inject oxygen into different water areas in the pool.

[0026] Working principle: When in use, when the sensor 5 detects that the water pollution in the pool exceeds the standard, the solenoid valve 222 opens the valve. At this time, the water level in the pool is higher than the highest point of the drain pipe 221 and the first end of the positioning air pipe 223, thereby forming a siphon effect, and the wastewater is discharged into the transfer barrel 21 through the drain pipe 221. When the water level in the breeding pond 1 drops to the lowest point of the positioning air pipe 223, the first end of the positioning air pipe 223 is exposed from the water and exposed to the air, and the air enters from the positioning air pipe 223 to the highest point of the drain pipe 221. At the elbow of the 32nd tube, the siphon effect ends and the drainage stops. Then, after entering the sedimentation barrel 31 through the first connecting pipe 23 and the second connecting pipe 322, it moves vertically from top to bottom, hits the baffle 323 at the lower end of the central pipe 321, slows down the water flow, and large particles of feces and residual bait are dispersed and precipitated into the bottom of the cone at the bottom of the sedimentation barrel 31. The separated clean water flows out through the overflow groove 324 to achieve solid-liquid separation. Then, the water is further filtered through the filter screen 33, which improves the safety of the purified wastewater. Through the water injection pipe 34 on the rear side of the filter screen 33, the water is filtered out. The water in the aquaculture pool 1 is sucked out through the drain pipe 221, and a vortex is formed in the center of the aquaculture pool 1, thereby driving the paddle 422 to rotate, and at the same time driving the shaft 421 to rotate, and the scraper 353 fixed on the outside of the shaft 421 is fixed to the outside of the shaft 421. The cleaning plate 423 is close to the bottom of the breeding pond 1. When it rotates, the sediment at the bottom of the breeding pond 1 is removed. At the same time, the sediment is discharged into the pond with the water flow, realizing automatic cleaning and reducing the pollution of the sediment to the water quality. When the waste water is discharged from the pond and refilled with water, the oxygen pump 43 starts to produce oxygen, and the oxygen is transported to the diversion pipe 443 through the oxygen supply pipe 442, and the oxygen is transported to the water through the set air stone 444. The oxygen supply part 44 rotates with the rotating shaft 421, and uniformly injects oxygen into different water areas in the pond.
