This application provides a sludge thickening device and method for an integrated aeration sedimentation tank, comprising: a tank with a conical zone at the bottom; a sludge inlet pipe with a dosing pipe connected in parallel at the top, the bottom end of the sludge inlet pipe passing through the center of the tank; sludge distribution pipes arranged in a cross shape and connected to the sludge inlet pipe; supernatant collection pipes distributed in the upper and middle parts of the tank and connected in parallel to the outlet; and an ultrasonic sludge level gauge fixed on one side of the top surface of the tank. By providing a dosing pipe and a pipe mixer at the front end of the sludge inlet pipe, the flocculant can be fully mixed with the sludge water in the pipe. By providing a sludge distribution pipe at the tail end of the sludge inlet pipe, the sludge mixed with the flocculant is evenly distributed throughout the tank, which can improve the sludge dewatering efficiency. At the same time, the conical zone can increase the sludge concentration, and a self-cleaning filter screen is provided above the sludge distribution pipe to further filter the sludge and improve the sludge dewatering speed.

The application discloses a kind of white burley tobacco roasting processing intensity characterization method, it is based on the two main objects leaf and hot air in heat transfer and mass transfer during white burley tobacco roasting process is analyzed, low boiling point volatile component in leaf is transferred to hot air with the volatilization of moisture in leaf during roasting process, the volatilization of low boiling point component in leaf is characterized using the volatilization of moisture in leaf, while the moisture saturation of hot air, namely moisture content, is used to control the speed of moisture mass transfer, from the total amount and speed of leaf and hot air mass transfer during white burley tobacco roasting process to characterize the processing intensity of white burley tobacco roasting machine.The application uses quantitative method to characterize the processing intensity during white burley tobacco roasting process, according to the quality characteristics and consumption demand of mixed cigarette product, different leaf roasting intensity is selected, to effectively guide mixed cigarette processing technology.

The utility model discloses an automatic rapid dehydration flocculation reaction kettle which comprises a kettle body, a stirring rod is arranged in the kettle body, a dehydration device is arranged in the kettle body, the dehydration device comprises a T-shaped pipe, the T-shaped pipe is fixedly connected to the top of the stirring rod, and the top of the T-shaped pipe is rotationally connected to the inner wall of the kettle body through a sealing bearing. The utility model relates to the technical field of flocculation treatment equipment, through the cooperation of the T-shaped pipe, the fixed box and the heating device, the air is heated by the heating device, the heated air enters the T-shaped pipe through the fixed box, when the pressure of the air in the fixed box is too high, hot air in the T-shaped pipe is extruded out, and the air in the T-shaped pipe is heated by the heating device. The hot air is blown to the inner wall of the kettle body, so that water drops in the kettle body are quickly evaporated, and the water body quickly flows downwards under the blowing of the air flow, so that the interior of the kettle body is quickly dehydrated, and the influence of the residual water drops on the subsequent flocculation treatment is avoided.
