Operation of aerating cell equipped with defoaming means
专利汇可以提供Operation of aerating cell equipped with defoaming means专利检索，专利查询，专利分析的服务。并且PURPOSE: To perform the pertinent conversion of night soil into compost while temperately using bubbles for the retention of heat, by detecting the temperature or pH of the night soil to switch and operate an aerator in the order of continuous, intermittent and continuous operations, and driving a bubble breaker or a liquid-spreading defoamer according to circumstances.
CONSTITUTION: In an aerating cell 1, a bubble breaker 10 is driven at a time for preparing the propagation of bacteria so that bubbles temperately remain on the liquid surface, and an aerator 2 is continuously driven to raise the temperature of the liquid 30. Hence, aerating air is inhaled through a muffler 15, an outer cylinder 11, an air-introducing pipe 9, the main body 7 of a nozzle, and the input of a motor 12 for the bubble breaker is also utilized for raising the temperature. When the condition comes to a stage for the propagation of bacteria, the temperature or pH is detected by a detector 24, and a motor 4 is switched into an intermittent operating state through a controller 27, an amplifying circuit 28 and an output circuit 29 to prevent overaeration. When the amount of bacteria comes up to the maximum value, the motor 4 is switched into the continuously operating state again through the detector 24 and the controller 27, the bubble breaker 10 is stopped, the pump 3 of an underwater motor is driven, and bubbles on the liquid surface are eliminated by a liquid-spreading type defoamer 23.
