Air floatation tank structure applied to sea culture of prawns and used for removing air floatation bubbles

Abstract

The invention relates to an improved structure for treating bubbles of air floatation equipment in a sea culture system of the prawns, in particular to an air floatation tank structure applied to sea culture of the prawns and used for removing air floatation bubbles. According to the air floatation tank structure, a wall body (9) of the air floatation tank is provided with a bubble overflowing port (2); the left and right sides of the bubble overflowing port (2) are provided with a groove (8) respectively; a flashboard (1) is inserted into the grooves (8); the upper side edge of the flashboard (1) is hinged with two swinging rods (3), the upper end of the flashboard (1) is rotatably connected with two fixing connection sleeves (6) respectively, and the inner walls of the fixing connection sleeves (6) are provided with inner threads of which the rotation directions are opposite to each other; shaft seats (5) are arranged on the wall body (9); a double-thread screw (7) penetrates through the two shaft seats (5); the front and rear parts of the double-thread screw (7) are provided with outer thread sections of which the rotation directions are opposite to each other; the two fixing connection sleeves (6) are screwed on the two outer thread sections of the double-thread screw (7); and one end of the double-thread screw (7) is provided with a hand wheel (4). By the air floatation tank structure, bubbles produced by air floatation water treatment equipment can be overflowed and discharged conveniently, the water quality condition of the prawn culture can be improved, and the yield and the quality of the prawns are improved.

Description

Technical field [0001] The invention relates to an air flotation tank, in particular to the structure of the air flotation tank, in particular to an improved structure for foam treatment of air flotation equipment in a seawater shrimp culture system. Background technique [0002] Prawns have high nutritional value and are high-protein nutritional aquatic products. [0003] Traditional shrimp aquaculture occupies a large area of ​​water and land resources, and is vulnerable to natural disasters, causing significant economic losses. The accumulation of harmful substances in the breeding process has caused a huge negative impact on the environment, and also brought great risks and difficulties to the development of shrimp aquaculture. In this environment, shrimp recirculating aquaculture has been gradually promoted throughout the country in recent years with the support of governments at all levels and the cooperation of scientific researchers due to the advantages of low water consu...

Problems solved by technology

At present, the air flotation technology has been successfully applied in the shrimp culture system, but in the actual shrimp production, there is a problem in the operation of this technology in the shrimp culture system: because different stages of shrimp culture require different water levels, the shrimp pond water The change of level causes the water level in the air flotation device to be unstable, which affects the discharge of air bubbles

However, the air flotation tank of the shrimp farming system only has water inside the tank body, and cannot form a sealed air chamber, which does not meet the conditions for use of this technical solution.

[0012] Patent No. 200920210411.8 "A Drainage Gate for Cultivation Pond" and Patent Application No. 201110105038.1 "A Classified Drainage Gate Plate for Sea Cucumber Culture Pond", which mainly provide drainage gates for discharging the bottom cultivation water, and cannot discharge surface water and air bubbles floating on the water surface , can not solve the problem of foam discharge in the air flotation tank of the shrimp farming system
