Description
Technical Field
The utility model relates to a direct fold filter screen core diesel blast pipe of soldering formula.
Background
For large diesel motor vehicles and diesel generators, exhaust gas discharged during operation contains a large amount of carbon deposition and smoke, it is known that filter screens in exhaust pipes are welded and formed with upper and lower filter screen covers after adopting a contraction port design, so that the filter effective area of the filter screens is greatly influenced (the contraction port wastes the effective filter screen area of 8cm-10 cm); therefore, the area of the filter screen can be increased by designing the direct type filter screen exhaust pipe, and the use efficiency is higher.
SUMMERY OF THE UTILITY MODEL
Technical problem to be solved
In order to solve the problems, the utility model provides a diesel engine exhaust pipe with a soldered direct folded filter screen core; the area of the filter screen under the filter element with the same volume is larger.
(II) technical scheme
The utility model discloses a direct fold filter screen core diesel blast pipe of soldering formula, include: the exhaust hood comprises a hood body, an exhaust inner pipe and a filter screen; an air inlet pipe extends out of the tail of the cover body; a pressure gauge is arranged on the air inlet pipe; the front end of the cover body is connected with the cover cap; an air outlet pipe extends out of the front end of the cover cap; the filter screen is a sintered cylindrical folded filter screen; two ends of the filter screen are provided with an upper filter screen cover and a lower filter screen cover; the upper cover and the lower cover of the filter screen are provided with through holes corresponding to folds of the filter screen; the filter screen penetrates through the through holes of the upper cover and the lower cover of the filter screen and then is fixed by tin soldering; the filter screen is sleeved on the exhaust inner pipe and is fixedly connected with the base in a sleeved mode through the lower cover of the filter screen; airflow holes are arrayed on the exhaust inner pipe; the front end of the exhaust inner pipe extends out of the connecting pipe and is connected with the cover through a threaded ring arranged at the front end of the connecting pipe.
