Abstract

The invention discloses a pond food field area contamination drainage system with the back flushing function. The system is characterized in that the contamination drainage system is composed of a pond bottom contamination drainage system and a back flushing system. When the contamination drainage system is used for feeding in a food field area, contamination is drained every other 3-5 days. According to the specific method, firstly, a contamination drainage valve is opened for draining contamination, then, the contamination drainage valve is closed, a back flushing pump is started, contamination drainage is performed again after the back flushing pump is turned off, and organic matter at the pond bottom of the food field area can be basically drained through 2-3 times of back flushing contamination drainage. According to the system, contamination drainage is thorough, accumulation of the organic matter at the bottom of the pond food field area is little, time is short every time contamination drainage is performed, fish feeding is not affected, good pond water quality can be kept, and the yield and the benefits of pond cultivation are increased; back flushing contamination drainage is continuously performed in the cultivation period, sludge at the pond bottom can be kept little for a long time, the effective water body of a pond is large, it is beneficial to yield increase, and besides, the pond does not need frequent large-scale dredging, and production cost can be reduced.

Description

A kind of food place, pond drainage that can recoil

Technical field

The present invention relates to fish production field, specifically a kind of food place, pond drainage that can recoil.

Background technology

In pond culture, pollute the heaviest, the region that organic matter accumulation is maximum, the food place of pond feedstuff feeding often, in this region, the accumulation of residual bait, gathering of fish faeces, the accumulation of other organic matters, fish food place is made to become the center of pollution source, some ponds for many years at the bottom of unclear pond, food place organic matter accumulation often reaches more than 1 meter, become the unstable region being easy to again to change of very easily anoxic, organic gathering in a large number not only makes pond shoal, effective water body reduces, also consume the dissolved oxygen in waters in a large number, reduce pond culture output and benefit, serious causes the even general pond of fish floating head, bring about great losses to breeding production.

Summary of the invention

For overcoming above-mentioned defect, the present invention devises a kind of food place, pond drainage that can recoil.

Technical scheme of the present invention is, a kind of food place, pond drainage that can recoil, it is characterized in that, drainage is made up of pond bottom blowdown system, backpurge system, and described pond bottom blowdown system comprises: at the bottom of the pond, food place of bottom is rendered as " recessed " font, the sewage draining exit of " recessed " font center, the blowdown cage above sewage draining exit, the blowdown isolation tooth of blowdown cage periphery, the blow-off pipe buried at the bottom of pond be connected with sewage draining exit, blowoff valve, sludge collecting ditch, described backpurge system comprises: recoil pump, recoil tube, near the ridge, pond being positioned at pond at the bottom of pond, described food place, at Chi Gengchu, feed throw-in machine is set, the dog-house of feed throw-in machine is in the face of food place, " recessed " font center of food at the bottom of pond, place arranges the sewage draining exit in 10-30 centimetres, diameter footpath, the top of described sewage draining exit arranges the blowdown cage of diameter 80-100 centimetres, described blowdown cage is spherical, the bottom side peripheral intervals 1-2 centimetres of blowdown cage arranges blowdown isolation tooth, described blowdown isolation tooth row dirt isolation tooth is the stainless steel rebar of diameter 0.5-1 centimetre, length 40-60 centimetres, wherein 20-40 centimetres of blowdown isolation tooth are inserted in bed mud at the bottom of pond, keep the height along 20 centimetres on blowdown cage and sewage draining exit, the bottom of described sewage draining exit is connected with blow-off pipe, blow-off pipe buries Yu Chidi, the other end of blow-off pipe leads to the sludge collecting ditch outside the ridge, pond, described sludge collecting ditch height above sea level is lower than blow-off pipe, blow-off pipe arranges blowoff valve near the opening of sludge collecting ditch, by the blowoff valve control of sewage disposal time, blow-off pipe upper shed in the inner side of blowoff valve connects recoil tube, and the opposite side of recoil tube arranges recoil pump, and described recoil pump is positioned at the clear water zone, upper strata of pond waters.

Beneficial effect: use drainage of the present invention, when eating place and throwing something and feeding, a blowdown is carried out at interval of 3-5 days, concrete grammar is, select the morning of 1-2 hours after having thrown something and fed, open blowoff valve, the organic matter that food pond, place prodelta clay is tired out relies on the pressure of water body, discharged with water by the blowdown isolation backlash of blowdown cage, be discharged to water quality become clear time, close blowoff valve, open recoil pump, aqueous reflux is made by recoil tube, at the bottom of recoil food pond, place, recoil after 2-3 minutes, close recoil pump, interval makes pollutant gather blowdown cage periphery for 5-10 minutes, open blowoff valve again and carry out blowdown, through 2-3 recoil blowdowns, organic basic discharge at the bottom of pond, food place can be made, blowdown of the present invention is thorough, and bottom food place, pond, organic matter accumulation is few, and each blowing time is short, on fish without impact, can keep good pond water quality, improves output and the benefit of pond culture, uninterruptedly recoil blowdown during cultivating, and pond also can be made to keep mud at the bottom of pond few for a long time, and the effective water body in pond is large, useful to raising output, and pond does not also need frequent extensive desilting in addition, can reduce production cost.
