Self-sinking microporous aerated pipe

Abstract

The invention relates to a self-sinking microporous aerated pipe, which is characterized by consisting of the following components in percentage by weight: 45 to 50 percent of PVC resin, 45 to 50 percent of plasticizer, 1 to 2 percent of external lubricant, 0.3 to 0.8 percent of internal lubricant, and 1 to 3 percent of stabilizing agent. The inner diameter of the aerated pipe is 6 to 12mm; 1 to 3 rows of micropores with the diameter of 0.2 to 0.3mm are formed on the pipe wall of the aerated pipe; the distance between adjacent micropores is 0.5 to 3cm; and the arrangement direction of each row of micropores is vertical to the pipe diameter of a gas pipe. The self-sinking microporous aerated pipe has the advantages that: the aeration capacity is improved, the gas transmission length is long, the micropores are hardly blocked by impurities and infiltrated water in the pipe is easily discharged.

Description

1. Technical field [0001] The invention relates to an aeration tube, in particular to a self-sinking microporous aeration tube. 2. Background technology [0002] Dissolved oxygen in water is a necessary condition for the survival of aerobic aquatic organisms. In order to ensure sufficient dissolved oxygen in the water of aquaculture ponds, it is necessary to aerate the bottom of the water to increase oxygen. The microporous aeration tube currently used needs to be loaded with a weight Only parts can sink into the bottom of the water, and the pore diameter of this kind of microporous aeration tube is only 20-30 μm. At the same time, when the air is input, because the pipe wall of the microporous aeration pipe is covered with micropores, the air transmission length of the fan to a single microporous aeration pipe does not exceed 50 meters, so every 50 meters needs to increase One air inlet and fan, thus the construction cost is high, and the operation and maintenance are comp...
