Abstract

The invention discloses an aquaculture system discharging sewage automatically. The aquaculture system comprises a culture pond, a funnel-shaped sewage sump, an L-shaped discharge pipe, a discharge control device, a sewage holding basket, a discharge tank, a discharge pipe, a water level control pipe and a water pushing pipe. The discharge control device is set to be an automatically-controlled drain valve and can be used for setting discharge frequencies and discharge time according to the feeding frequencies of fed animals; and after the animals are fed for a certain period of time, residual feeds, excrement, animal carcasses and the like are collected into the funnel-shaped sewage sump under the action of annular flowing water flow; and the automatically-controlled drain valve is automatically switched on to discharge the pollutants, so that the pollution caused by the residual feeds, the excrement, the animal carcasses and the like on the aquaculture water bodies is avoided, and the probability of outbreak of diseases of aquatic livestock is reduced.

Description

A kind of cultivating system of automatic pollution discharge
Technical field
The invention belongs to field of aquaculture devices, relate to particularly a kind of cultivating system of automatic pollution discharge.
Background technology
Along with the continuous expansion of aquaculture scale and intensive degree improve day by day, the cultivation self-pollution becomes the key factor of environmental pollution.And the deterioration of breeding environment often becomes the inducement that disease occurs, and becomes to a certain extent the deciding factor of aquaculture success or not.About discharging pollution in pool device and structurally associated technology comprise the cooking-pot type pond at the bottom of, central blowdown pipe, blowdown collecting pipe, the fixedly draining of blow-off line, industrial circulating water cultivating system and blowdown apparatus etc.In actual production process, the blow-off line that exposes the bottom surface, pond affects the activity of aquatic livestock.Along with the raising of cultivation density, the trend of dirt accumulation appears at the bottom of the breeding production middle and later periods pond, particularly there is part blowdown dead angle.Build up of dirt in the pond, worsen the severe contamination breeding water body, further have influence on the economic benefit of aquaculture.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of cultivating system of automatic pollution discharge, this system can be efficiently discharge rapidly the dirts such as residual bait in the culturing pool, ight soil, spoil timely, solved existing culturing pool untimely because of blowdown, thoroughly do not cause the problem of cultivated animals outbreak of disease.
The present invention is achieved through the following technical solutions:
A kind of cultivating system of automatic pollution discharge, comprise culturing pool, the funnel type sewage sump, " L " type blow-off pipe, horizontal blow-off pipe, the blowdown control device, receive dirty basket, dirt discharge groove, blow-off pipe, water level control pipe and push away the water device, the funnel type sewage sump is positioned at the culturing pool centre bottom, termination under the funnel type sewage sump " L " type blow-off pipe, the height of " L " type blow-off pipe is lower than the height of culturing pool, and be higher than the water surface for aquaculture in the culturing pool, " L " type blow-off pipe upper end communicates with air, on " L " type blow-off pipe vertical pipe, be tightly connected by a three-way pipe and a horizontal blow-off pipe, the blowdown control device is housed on the horizontal blow-off pipe, below the mouth of pipe of horizontal blow-off pipe, be provided with and receive dirty basket, the dirty basket of receiving is arranged on the dirt discharge groove top, the dirt discharge groove lower end is connected with blow-off pipe, 2-10 pushes away the water device and is same direction slant setting in culturing pool, make the interior current of culturing pool circularize mobile, described water level control pipe is inside and outside " U " type pipe of a connection culturing pool, be positioned on part " U " the type pipe of culturing pool and have osculum, and " U " type pipe is higher than the cultivation water level.
Further, described culturing pool is circular, is pot bottom type at the bottom of the culturing pool.
Further, described blowdown control device is valve.
Further, described blowdown control device is an automatic control of sewage disposal valve, and this blowoff valve can arrange blowdown number of times and blowing time.
Further, described receiving is provided with net cage in the dirty basket, receives in the dirty basket so that the cultivated animals of discharging with dirt is temporarily stored in.
Further, described horizontal blow-off pipe upper wall is 20-40cm apart from the height of water surface for aquaculture in the culturing pool.
Further, the described water device that pushes away comprises the gentle stone of arc pvc pipe, and the arc pvc pipe is that a pvc pipe cuts formation along longitudinal middle axis, and the arc pvc pipe tilts to put in the culturing pool, gas stone is equipped with in an end arc inboard at the bottom of the arc pvc pipe pond, and the arc pvc pipe becomes 30-60 degree angle with horizontal plane.
The present invention's beneficial effect compared with prior art:
Push away the water device by in arc pvc pipe bottom gas stone being housed among the present invention, air-flow makes under the effect of arc pvc pipe that current circularize mobile in the culturing pool, residual bait in the water, ight soil, the dirts such as spoil sink in the funnel type sewage sump in the water rotary course, when fetching boiling water control device on the flat blow-off pipe, because horizontal blow-off pipe upper wall is 20-40cm apart from the height of water surface for aquaculture in the culturing pool, under the poor effect of level pressure, dirt in the funnel type sewage sump is discharged into rapidly to be received in the dirty basket, because blowing time is short, so having hardly cultivated animals is discharged from, even there are once in a while indivedual weak cultivated animals to discharge with dirt, also can be by a net cage being set in the dirty basket the individual temporary transient survival that is discharged from is being received in the net cage in the dirty basket receiving.
The horizontal blow-off pipe upper wall of the present invention is 20-40cm apart from the height of water surface for aquaculture in the culturing pool, and level pressure is poor can thoroughly get rid of dirt at the bottom of the pond, has avoided again simultaneously because level pressure is poor excessive and to the cultivated animals injury.
Blowdown control device of the present invention is arranged to automatic control of sewage disposal valve, can set blowdown number of times and blowing time according to the number of times of throwing something and feeding of cultivated animals, behind certain hour that cultivated animals is thrown something and fed, residual bait in the culturing pool, ight soil, spoil etc. gather in the funnel type sewage sump under the current of annularly flow, automatically the control of sewage disposal valve is opened the eliminating dirt automatically, avoided because of the pollution to breeding water body such as residual bait, ight soil, spoil, reduced the probability that aquatic animal disease breaks out.
