Abstract
The invention discloses a front sewage disposal device of an industrial aquaculture circulating water system. Three holes with diameters about 8cm are cut in the wall of a culture pond water drainage pipe to serve as sewage draining exits, in addition, a plastic pipe with the outer diameter equal to the inner diameter of the water drainage pipe serves as a drain valve, and the drain valve is inserted into the water drainage pipe to block or dredge the sewage draining exits. Compared with an existing circulating water system, the front sewage disposal device has the advantages that the problem that blocking is easily caused due to the fact that only an arc-shaped sieve or a microfiltration machine in the system is used for filtering a great amount of sludge is solved, rinsing and backwash frequency of the arc-shaped sieve and the microfiltration machine is reduced by about 60%, meanwhile, the problems that a part of sludge is broken, dissolved, scattered and leaked across the arc-shaped sieve or the microfiltration machine to enter a biological treatment process due to the fact that water circulation management is long in the system are solved, pressure of the system is relieved, and use efficiency of the system is improved by 50%.
Description
[technical field]
The invention belongs to aquaculture field, relate to a kind of blowdown apparatus being applied to before industrial aquaculture circulation.
[background technology]
In industrial aquaculture, because of a large amount of bait throwing in, its residual bait, ight soil etc. form mud at the bottom of being sunken in a large number pond, these mud are itrogenous organic substance, under the effect of bacterium, be decomposed into the materials very harmful to fishes and shrimps such as ammonia nitrogen, nitrous acid nitrogen, hydrogen sulphide, and these mud are also the hotbeds of bacterium, virus breeding.Therefore remove in time mud, be extremely important work during industrial aquaculture is produced.
At present, what in industrial aquaculture, adopt is circulation, in system, be by water circulation pipe, to utilize sieve bend or Microfilter to concentrate in these mud to carry out filtration treatment, in this process, there are two problems, the one, a large amount of dirts depends merely on sieve bend or Microfilter filters, easily make it stop up, need frequent scrubbing and recoiling; The 2nd, water circulation pipe is longer, and part dirt is can be under the effect of current broken, leach into nano sized particles, and leaks sieve bend or Microfilter, enters the biologic treatment process problem in circulation.
[summary of the invention]
The object of the invention is, design a kind of can be by most of sludge discharge device before circulation, to address the above problem.
The present invention realizes by the following method: be hole at 3 diameter 8cm of culturing pool draining tube wall cutting as sewage draining exit, what alternative was external diameter in order to drainpipe internal diameter moulds pipe as draining valve, draining valve is inserted in drainpipe, to stop up or to open sewage draining exit.
The invention has the beneficial effects as follows: under the effect of the rotary water current in pond of the mud in industrial aquaculture pond, focus on central authorities at the bottom of pond, regularly blowoff valve is extracted in the drainpipe of ground, pool bottom sludge just flows out outside pond along with the sewage draining exit of current on filter pipe, subsoil drain, ground drainpipe, finally focuses on.The present invention compares with existing circulation, not only solved and in system, depended merely on sieve bend or Microfilter filters a large amount of mud and blockage problem easily occurs, reduced the number of times approximately 60% of scrubbing, backwash of sieve bend and Microfilter, and it is long to have solved system internal cause water circulation management, part sludge crushing, leach and leaked sieve bend or Microfilter enters biologic treatment process problem, alleviate the pressure of system, improved the service efficiency 50% of system.
[accompanying drawing explanation]
Figure of description is structural representation of the present invention.
In figure: 1-culturing pool, 2-filter pipe, 3-subsoil drain, 4-be drainpipe, 5-blowoff valve handle, 6-blowoff valve, 7-sewage draining exit on the ground.
[embodiment]
Describe structure and the using method of the front blowdown apparatus of industrial aquaculture circulation of the present invention below in detail:
This device be hole at 3 diameter 8cm of culturing pool draining tube wall cutting as sewage draining exit, what alternative was external diameter in order to drainpipe internal diameter moulds pipe as draining valve, draining valve is inserted in drainpipe, to stop up or to open sewage draining exit.
Concrete operations are as follows: under the effect of the rotary water current in pond of the mud in industrial aquaculture pond, focus on central authorities at the bottom of pond, regularly blowoff valve is extracted in the drainpipe of ground, pool bottom sludge is just along with the sewage draining exit of current on filter pipe, subsoil drain, ground drainpipe flows out outside pond, finally focus on, after blowdown finishes, blowoff valve is inserted in the drainpipe of ground, culturing pool enters normal circulation again.
2011～2012, prosperous Yongfeng, Tianjin aquaculture Co., Ltd applied this device and carries out lefteye flounder industrial aquaculture, and the effect of removing contamination is remarkable, and circulation efficiency greatly improves.The existing a set of circulation of company in 2011, former 2 workshops 4000m altogether that guarantees
2operation, applies after this device, brings up to and guarantees 3 workshops 6000m altogether
2normal operation, circulation efficiency has improved 50%, has reduced the number of times approximately 60% of scrubbing, backwash of sieve bend and Microfilter simultaneously.Tianjin in 2012 prosperous Yongfeng aquaculture Co., Ltd applies this device cultured area and expands whole workshops 20000m altogether to
2.This device has been generalized to periphery 300000m in 2012
2cultivating workshop.
