2results about How to "Less smoke" patented technology

The application is a kind of air supply structure of pellet stove, including combustion chamber and oil receiving tray, the peripheral wall of the air duct shell of the combustion chamber is spaced apart from the peripheral wall of the combustion cup, the top end of the air duct shell is provided with air duct cover, and the top end of the combustion cup is provided with combustion cover; the side wall of the combustion cup, the air duct cover and the combustion cover are all provided with air guide hole; the spiral airflow generated by the airflow sent into the air duct shell by the air supply fan and passing through the air guide hole evenly spreads the fire and heat wave in the combustion cup to the bottom of the oil receiving tray; the left and right ends of the bottom of the oil receiving tray are oppositely provided with fire outlet, the middle of the two fire outlets is provided with fire tray, the fire outlets at the left and right ends emit fire from the edge to the center of the oil receiving tray, and the fire tray emits fire from the lower end to the upper end of the oil receiving tray, which can better realize the uniform distribution of fire and heat wave to the surface of food, the structure of spiral airflow can spread the fire and heat wave, which can fully promote the full combustion of pellet fuel in the combustion chamber, better release heat, and reduce smoke.

This invention discloses a method for solving the problem of smoke interference during photography in blasting light testing. Specifically, it is a method for solving the problem of smoke interference during blasting caustic lines, moving light projectiles, and DIC experiments. The device includes a smoke-controlling explosive TATP, a clamp with three functions: blocking, smoke control, and smoke guiding, a smoke-blocking and smoke-venting pipe, an elastic loading block, a freely height-adjustable frame, and bolt posts. The smoke-controlling explosive TATP is loaded into the borehole. A sealing ring is placed on the grooved side of the clamp. A certain width of the outer sealing ring is cut off, and a guide groove of the same width is opened above the clamp, which then contacts the surface of the specimen. The center of the clamp is on the same horizontal line as the center of the borehole. A smoke-blocking and smoke-venting pipe with a diameter slightly larger than the clamp's diameter is placed outside the clamp, with a rubber pad attached to the side that contacts the specimen. A smoke-venting slit of a certain width is opened on the side wall, and the guide groove is aligned with the smoke-venting slit to form a smoke guiding channel. An elastic loading block with a central opening abuts one side against the end face of the smoke-blocking and smoke-venting pipe without the rubber pad, and the other side is penetrated by a bolt post on the frame, abutting against the frame. Finally, the bolt post passes through the elastic loading block, the clamp, and the smoke-blocking and smoke-venting pipe. Adjusting the bolt post makes the clamp fit tightly against the specimen, and the elastic loading block abuts against the smoke-blocking and smoke-venting pipe, fitting the surface of the specimen. The method of this invention can effectively control smoke from firing, improve experimental shooting, and enhance experimental accuracy.
