AI Technical Summary

Technical Problem

The existing automatic sewage discharge device for circulating water farming of land-based circular pools cannot adjust the water discharge according to the actual amount of dirt, resulting in untimely or excessive sewage discharge, and there are problems of safety risks and inefficiency.

Method used

An automatic sewage discharge device is designed including a water inlet pipe, a sewage discharge pipe and a number of water level pipes of different lengths. The water discharge volume is adjusted through different lengths of the water level pipe, and the siphon principle and snorkel structure are used to achieve automatic discharge and stop functions.

Benefits of technology

The drainage volume is adjusted according to the actual amount of dirt, ensuring the timely, automatic, effective and thorough discharge of dirt in the land-based round pool, reducing the risk of breeding, and improving the stability and service life of the device.

Abstract

The utility model discloses an automatic pollution discharge device for land-based round pond recirculating aquaculture, belongs to the technical field of land-based round pond aquaculture, and solves the problem that pollution discharge is not thorough due to the fact that the water discharge amount of an existing culture pond cannot be adjusted according to the actual pollution amount. The device comprises a water inlet pipe and a blow-off pipe, the water inlet pipe is installed above the land-based round pool, the blow-off pipe is installed at the bottom of the land-based round pool, the device further comprises at least two water level pipes, the at least two water level pipes are inserted into the land-based round pool, the lengths of the water level pipes are different, a valve is installed on each water level pipe, and the water level pipes are communicated with the blow-off pipe. The tops of the at least two water level pipes are jointly communicated with a breather pipe with the two ends closed, the breather pipe is communicated with a connecting pipe, the end, away from the breather pipe, of the connecting pipe is communicated with a U-shaped pipe, and one end of the U-shaped pipe is communicated with a blow-off pipe. According to the automatic sewage discharging device, the water discharging amount can be adjusted according to the actual sewage amount, and sewage in the land-based round pool can be discharged timely, automatically, effectively and thoroughly.
