Abstract

The utility model discloses a front sewage sludge discharging device of an industrial aquaculture circulation water system, and three holes are cut in a water drainage pipe wall of a culture pool to serve as sewage sludge discharging ports, wherein diameters of the holes are respectively 8cm. in addition, a plastic pipe serves as a drainage valve, wherein the inner diameter of the water drainage pipe serves as the outer diameter of the plastic pipe. The drainage valve is inserted into the water drainage pipe so as to block or dredge the sewage sludge discharging ports. Compared with an existing circulation water system, the front sewage sludge discharging device of the industrial aquaculture circulation water system not only solves the problem that due to the fact that in the system, only an arc-shaped screen or a microstrainer is used for filtering a large quantity of sludge, the blocking is prone to happening, and reduces times of washing and backwashing of the arc-shaped screen or the microstrainer by 60%, but also solves the problems that due to the fact that a water circulation pipeline is long in the system, parts of sludge are broken and dissolved and scattered to leak out of the arc-shaped screen or the microstrainer and enter the biological treatment process, the pressure of the system is reduced, and the using efficiency of the system is improved by 50%.

Description

Blowdown apparatus before the industrial aquaculture circulation

[technical field]

The utility model belongs to aquaculture field, relates to a kind of front blowdown apparatus of industrial aquaculture circulation that is applied to.

[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 the pond, these mud are itrogenous organic substance, be decomposed into the material very harmful to fishes and shrimps such as ammonia nitrogen, nitrous acid nitrogen, hydrogen sulphide under the effect of bacterium, and these mud are also the hotbeds of bacterium, virus breeding.Extremely important work during industrial aquaculture is produced therefore in time remove mud.

At present, what adopt in industrial aquaculture is circulation, to utilize sieve bend or Microfilter to concentrate by water circulation pipe in these mud to carry out filtration treatment in system, there are two problems in this process, the one, a large amount of dirts depends merely on sieve bend or Microfilter filters, it is stopped up, need frequent scrubbing and recoiling; The 2nd, water circulation pipe is longer, and the 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 purpose of this utility model is, design a kind of can be with most of sludge discharge device before circulation, to address the above problem.

The utility model is realized by the following method: be to cut the hole of 3 diameter 8cm as sewage draining exit at culturing pool draining tube wall, alternative in order to the drainpipe internal diameter be external diameter mould pipe as draining valve, draining valve is inserted in drainpipe, to stop up or to open sewage draining exit.

The beneficial effects of the utility model are: focus on central authorities at the bottom of the pond under the effect of the mud rotary water current in the pond in the industrial aquaculture pond, regularly blowoff valve is extracted in the drainpipe of ground, pool bottom sludge just flows out outside the pond along with the sewage draining exit of current on filter pipe, subsoil drain, ground drainpipe, focuses at last.The present invention compares with existing circulation, not only solved and depended merely on sieve bend or the Microfilter a large amount of mud of filtration in system and blockage problem easily occurs, reduced the number of times 60% of scrubbing, backwash of sieve bend and Microfilter, and it is long to have solved the management of system internal cause water circulation, the part sludge crushing, leach and leaked sieve bend or Microfilter enters the biologic treatment process problem, alleviate the pressure of system, improved the service efficiency 50% of system.

[description of drawings]

Figure of description is structural representation of the present utility model.

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]

The below is described in detail structure and the using method of the front blowdown apparatus of the utility model industrial aquaculture circulation:

This device be hole at 3 diameter 8cm of culturing pool draining tube wall cutting as sewage draining exit, alternative in order to the drainpipe internal diameter be external diameter mould pipe as draining valve, draining valve is inserted in drainpipe, to stop up or to open sewage draining exit.

Concrete operations are as follows: focus on central authorities at the bottom of the pond under the effect of the mud rotary water current in the pond in the industrial aquaculture 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 the pond, focus at last, 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 used this device and carries out lefteye flounder and cuttlefish industrial aquaculture, and the effect of removing contamination is remarkable, and circulation efficient greatly improves.The existing cover circulation of company in 2011, former 2 workshops 4000m altogether that guarantees ²Operation after using this device, is brought up to and is guaranteed 3 workshops 6000m altogether ²Normal operation, circulation efficient has improved 50%, has reduced simultaneously the number of times 60% of scrubbing, backwash of sieve bend and Microfilter.Tianjin in 2012 prosperous Yongfeng aquaculture Co., Ltd uses this device cultured area and expands whole workshops 20000m altogether to ²This device has been generalized to peripheral 300000m in 2012 ²Cultivating workshop.

Claims

1. blowdown apparatus before an industrial aquaculture circulation, it is characterized in that cutting the hole of 3 diameter 8cm as sewage draining exit at culturing pool draining tube wall, alternative in order to the drainpipe internal diameter be external diameter mould pipe as draining valve, draining valve is inserted in drainpipe, to stop up or to open sewage draining exit.
