Description
Technical Field
The invention belongs to the technical field of aquaculture, and particularly relates to a double-arc-shaped continuous concentration and pollution discharge device and method for a shrimp culture system.
Background
In a shrimp culture system, in order to ensure that the culture system maintains a good water quality environment, the waste such as residual bait, excrement, shrimp shells, dead shrimps and the like needs to be discharged out of the culture system in time. The shrimp culture sewage discharge system is basically characterized in that various pollutants are gathered near a sewage discharge outlet at the center of the bottom of a pot-shaped pool by promoting water flow to rotate, and then the pollutants are discharged out of the culture system through a sewage discharge pipe under the action of water pressure difference. An escape-proof net is required to be arranged at the sewage outlet to prevent live shrimps from being discharged, but shrimp shells, sick shrimps and dead shrimps are difficult to discharge at the same time, so that the escape-proof net is blocked; because the escape-proof net is arranged underwater, the escape-proof net is difficult to replace during cultivation, and further the pollution discharge effect is reduced, and sick shrimps and dead shrimps are easy to decay and decompose and further pollute the water, so that some shrimp cultivation systems are additionally provided with dead shrimp and sick shrimp pollution discharge pipelines simultaneously and are independently controlled, but the discharge of live shrimps cannot be prevented. Therefore, when live shrimps are prevented from escaping, dirt such as shrimp shells, dead shrimps, ill shrimps with poor vitality, residual bait, excrement and the like in the culture water body is discharged out of the culture system in time, and the method is a key technology for successfully culturing the shrimps.
A Chinese utility model patent with publication number CN203735271U, which was published in 2013, 7, month and 30, discloses a high-level shrimp pool floating ball type sewage drainer; the device can effectively discharge the shrimp shells out of the pool, and is difficult to overhaul and replace during cultivation due to being arranged at a drain outlet at the bottom of the high-position shrimp culture pool. The Chinese patent invention with publication number CN105724307A, which is disclosed in 2016, 7, 6, discloses an air-lift type decontamination device suitable for indoor industrial shrimp culture; the device releases the bubble when passing through the blowdown, and the frightening live shrimp leaves the drain and is not discharged, then through gaseous promotion drain apron, gets rid of the dead shrimp in shrimp pond, the bad sick shrimp of vigor, incomplete bait, excrement and urine fast. However, the device is provided with a sewage discharge sleeve and a chassis which are also provided with the bottom of the aquaculture water body, dead shrimps, ill shrimps with poor vitality, residual bait and excrement are difficult to be discharged and observed, the live shrimps can still be taken out by water flow and are difficult to be noticed during sewage discharge, and the device is provided with a movable part, so that the water can be easily blocked by foreign matters. The Chinese invention patent with publication number CN109452215A, which is disclosed on 12.3.2019, discloses a device and a method for removing dirt and preventing live shrimps from escaping in a circulating water shrimp culture system, and the Chinese invention patent with publication number CN110278911A, which is disclosed on 27.2019, provides a split type surface dirt collector suitable for the live shrimps of the circulating water shrimp culture system to automatically return to a pond. The two devices provided by the invention can collect shrimp shells, dead shrimps and ill shrimps with poor vitality and prevent overflow from escaping the shrimps, but the overall structure of the dirt collector is more complex, residual bait and excrement are required to be connected into a subsequent separation device for further separation treatment, the dirt collector can only be used in a circulating water culture system in a matched manner, a water pump and other series of auxiliary equipment are required for the subsequent separation treatment, the investment cost and the energy consumption are higher, and the dirt collector is difficult for general farmers to bear. Therefore, research and development one kind can effectively concentrate shrimp shell, dead shrimp, the bad sick shrimp of vigor and filth and in time discharge, and then reduce the blowdown water yield, can also prevent simultaneously that the live shrimp from escaping, easy access, simple structure's waste fitting discharging has important meaning to promoting the high density of shrimp breed.

Compared with the prior art, the invention has the advantages that: when the aeration nanotube in the air stripping pipe starts to work, dirt (residual bait, excrement, shrimp shells, dead shrimps and ill shrimps with poor vitality) deposited at the bottom of the pond is sucked and flows out through the long holes in the horizontal pipe, and is continuously filtered and intercepted through two arc sieves, wherein the first arc sieve is a coarse arc sieve, the meshes of the sieve are large, only the shrimp shells, the shrimp bodies and the like with larger sizes are intercepted, and the residual bait and the excrement fall to the second arc sieve through the first arc sieve; the second sieve is a fine sieve with small meshes, the residual bait and excrement are intercepted and concentrated, and the filtered water directly falls back to the culture pond. In operation, the live shrimps intercepted on the first coarse sieve can jump out of the low baffle plates on two sides of the collecting tank by jumping and return to the culture pond. The shrimp shell, dead shrimps and ill shrimps with poor vitality are intercepted by the first sieve bend and fall into the collecting tank, and are manually removed every day. The residual bait and excrement intercepted on the second curved sieve gradually slide into the collecting hopper under the action of water flow scouring, and are manually collected and cleaned at regular intervals.
(1) The device provided by the invention overcomes the defect that the drain outlet at the bottom of the shrimp culture pond is easily blocked by the escape-proof net, the escape-proof net and the sewage disposal and sewage interception device are arranged on the surface layer, so that timely sewage disposal is realized, the removal conditions of shrimp shells, dead shrimps, sick shrimps and residual bait excrement can be effectively mastered in the whole culture process, meanwhile, live shrimps can automatically return to the culture water body, and the shrimp shells, the dead shrimps and the sick shrimps with poor vitality can be conveniently and manually removed. Dead shrimps and residual bait in the shrimp culture can be found and mastered in time.
(2) The two sieve bows are movable and convenient to replace and clean, and the first sieve bows can be conveniently replaced with sieve bows of different specifications in different breeding stages.
(3) The water consumption for sewage discharge is low. Because the second sieve bend can concentrate the residual bait excrement and urine, can greatly reduce the blowdown water consumption in breeding.
In conclusion, the double-arc-shaped continuous concentration and pollution discharge device and method for the shrimp culture system are suitable for culture ponds with various shapes in the existing shrimp culture system, particularly solve the problem that shrimp shells, dead shrimps and pollutants are difficult to discharge in high-density industrial culture, and effectively prevent live shrimps from escaping; the invention can be used for timely mastering the conditions of dead shrimps, excessive baits and the like at the bottom of the pond.
