Abstract

PURPOSE: A circulating sedimentation drainage pipe is provided to prevent breakdown, abrasion and operation cost related with the use of valve and effectively control drainage amount of circulation water and supplementation water by performing draining and sedimentation only with the pipe. CONSTITUTION: Draining of a breeding cage(7) is performed to circulating sedimentation tank(8) via a drainage connection pipe(5) joined by connection nuts(6). A total drainage pipe(3) is installed on a total drainage path(9) for a complete drainage. An elbow-type supplementation water drainage elbow(4) is attached on top of the total drainage pipe(3) to induce natural discharge of circulation water and supplementation water.

Description

Circulation Settling Drainage Pipe {.}

While the prior art of the present invention is a system for manually adjusting or draining directly from a breeding tank using various valves, etc., during land raising,

The present invention considers frequent failures and inefficiencies by applying a substitute valve as a drain pipe for minimizing reuse of breeding water and minimizing water pollution by forming a circulation settling furnace.

There is no special technical problem because it is a device structure of system rather than technology.

When the breeding water is drained through the drain pipes 1 and 1 'in the breeding tanks 7 and 7', the circulating sedimentation pipes 2 and 2 pass through the connecting pipes 5 and 5 'by the coupling nuts 6 and 6'. 2 ') and discharge into the natural circulation sedimentation tank (8,8'),

Replenishment drainage valve (4,4 ') so that the sludge etc. sinks on the bottom of the circulation settling furnace (8,8') while being circulated by the separate circulation pump, and the water level can be adjusted freely as much as the supplementary quantity obtained separately. As a structure in which the supplementary water is circulatedly injected, most of the water is discharged to the entire individual breeding tank (7,7 ') to the circulating settling furnace (8,8') and the supplemental drainage valve (4,4 ') is added by a small amount of the supplementary water. System for adjusting the key to evenly drain each tank through)

In addition, when the breeding is completed or the tank cleaning, the total drainage pipe (3, 3 ') that is inserted or separated by the top and bottom tapping simply by manually separating from the socket is a system invention that can be easily drained completely.

1. Minimize facility cost and exclude repair cost because no valve is used

2. Easy to clean by easy installation

3. No valve adjustment by automatic drainage

4. Uniform discharge of individual tank circulation and replenishment

5. Easy to separate and use by tank

6. Maximize sedimentation efficiency by applying long cycle sedimentation furnace

7. Biofiltration filter can be applied to circulation settler to reduce drainage pollution

8. If the pallet is installed on the total drainage path, the work efficiency will be improved by using the balance as the passage role.

Claims (1)

While the drainage of the breeding tanks 7 and 7 'is naturally drained to the circulating settling tanks 8 and 8' through the drain connection pipes 5 and 5 'by the coupling nuts 6 and 6', A total drainage pipe (3, 3 ') is formed in the total drainage passage (9) for complete drainage, and an elbow type supplemental water drainage elbow (4, 4') is detachably attached on top of the total drainage pipe (3, 3 '). Circulation sedimentation drain pipe to induce natural discharge of circulating water and replenishment drainage as uniform as replenishment water for each tank
