Abstract
The invention discloses a water circulating accelerator for industrialized fishponds. A spiral isolation strip is added to a square fishpond. The isolation strip is built by bricks and located at a position from a water feeding inlet to a central sewage draining outlet and away from the pond wall by a distance of one quarter of the pond wall edge. After modification, water flow and direction can be controlled to accelerate water circulating, and accordingly dirt in the fishpond can be driven to move towards the central sewage draining outlet and drain out conveniently.
Description
[technical field]
The invention belongs to the recycling technology field, relate to a kind of pool water circulation accelerating device for industrial fish farming that is applied to.
[background technology]
In the industrial aquaculture, recycling technology more and more is widely used.The main solid particle that exists is residual bait and the fish faeces of throwing something and feeding in circulating water culture system (RAS), and these solid waste are not of uniform size, and character is in the majority with organic particulate matter.These materials are present in the water can consume oxygen in water, and dissolved oxygen is reduced.Under ammoxidation and nitrification, produce nitrogen nitrogen and nitrite nitrogen, the aquaculture organisms such as harm fish.Gathering is also removed the important content that these dirts then are recycling technologies.According to the study, account for about 50% of total organic granular total amount greater than the solid particle of 100 μ m, this part particle is suitable for removing with gravitational settling or hydraulic cyclone technique.Settling methods need to be joined separately and built the gravitational settling facility, and expense is higher.Hydraulic cyclone technique is adapted to the culturing pool of rectangular jatharapanvartanasana.
Present industrial aquaculture pond is square, and Chi Jiao does arc process, area 50m
2About, adopt straight-line fish culture in running water mode more, change water every day 2 times, day rate of water exchange 200%, the method for at every turn changing water is, use the instrument such as whisk broom with the pond at the bottom of dirt be swept to the central blow-down mouth, then water washes down.
In present existing industrial aquaculture pond, adopt recycling technology, because culturing pool planning construction is finished, the unlikely rectangular jatharapanvartanasana that is fit to the hydraulic cyclone technology that again the pond type changed into can not be built independent gravity settling basin at existing cultivation pool side.But because area is large, current disperse, waterpower is little again in existing square pond, can not change water and will assemble and remove greater than the solid particle of 100 μ m by adding, and this has become the bottleneck problem of application cycle water technology in existing square culturing pool.
[summary of the invention]
The objective of the invention is, design a kind of device that can in existing square culturing pool, improve water circulating speed, to address the above problem.
The present invention is by going to realize such as the below: in square industrialized fish pond, self-watering mouth place is to the Central Drainage mouth, along the distance apart from pool wall 1/4 length of side, fill an isolation strip with brick, add when changing water in the pond, by rule bundle water (flow) direction and flow, reach the acceleration water circulation, dirt moves and discharges to the central blow-down mouth in the crawl in order to driving.
The obvious difference of the more existing crawl of the present invention is to install the spirality isolation strip in square industrialized fish pond additional, its beneficial effect is: continue to add water by the filler, can accelerate the flow velocity of Chi Shui, make the solid particulate matter that falls at the bottom of the pond, along with spiral current, flow to the sewage draining exit of pond central authorities, and in this gathering discharge, also can until solid particle after sewage draining exit is assembled, open the valve of blow-off pipe, discharge dirt, reach the purpose of collecting the solid particle dirt.
[description of drawings]
Figure of description is structural representation of the present invention.
Among the figure: 1-crawl, 2-drainpipe and valve, 3-Central Drainage mouth, 4-spirality isolation strip, 5-inlet valve, 6-water inlet pipe
[embodiment]
The below is described in detail structure and the using method of pool water circulation accelerating device for industrial fish farming of the present invention:
This device is to install the spirality isolation strip additional to consist of in square culturing pool.In square industrialized fish pond, self-watering mouth place is to the Central Drainage mouth, along the distance apart from pool wall 1/4 diameter, fills an isolation strip with brick.Add when changing water in the pond, by rule bundle water (flow) direction and flow, reach the acceleration water circulation, dirt moves and discharges to the central blow-down mouth in the crawl in order to driving.
Concrete operations are as follows: install the spirality isolation strip additional in nearly square industrialized fish pond, and use the cement Troweling press finishing.Add water by the filler circulation, improve the flow velocity of Chi Shui, make to fall to the also solid particulate matter at the end, take the lead in flowing to the sewage draining exit of pond central authorities along with spiral current, and assemble discharge at this, also can until solid particle after sewage draining exit is assembled, open again the valve of blow-off pipe, discharge dirt.
2011, prosperous Yongfeng, Tianjin aquaculture Co., Ltd used this device and carries out the Cynoglossus semilaevis circulating water cultivation, and collection is dirty, filth-discharging effect is remarkable.3 mouthfuls of altogether 150m were reequiped on July 6
2Culturing pool.By adding water, cause and formed rotary water current in the pond, even also gathered the central blow-down mouth with current greater than the solid particle of 100 μ m.According to measuring and calculating, 98% solid particle can be discharged by sewage draining exit, carries out the labor cleaning one time at the bottom of only needing a week to the pond.Not only carry out effective the linking with circulating water equipment by this transformation, and reduced the labour intensity that has reduced the workman.50 mouthfuls of altogether 2500m were reequiped again on July 20
2Culturing pool, effect is better.
