Embodiment Construction
[0010] The present invention is described in conjunction with accompanying drawing and specific embodiment:
[0011] like figure 1 As shown, a counter-type vortex exhaust device, the exhaust device has an exhaust volute 1 with an open upper end surface; the bottom surface of the exhaust volute 1 is perpendicular to the bottom surface of the exhaust volute to divide the inner cavity of the exhaust shell It is a partition plate 6 with two inner cavities; the corresponding side walls of the exhaust volute have inwardly recessed pits, and the bottom surface of the pits has a channel that communicates with the inner cavity of the exhaust volute. holes; the through holes on the two pits communicate with the two inner cavities respectively; the bellows 3 are arranged in the pits, and the bellows 3 protrude from the corresponding pits; The two ends of the corrugated pipe 3 are provided with mounting flanges 7 respectively; The outer diameter of the flanging is smaller than the inner...

The invention belongs to the technical field of diesel engine exhaust, and provides a direct-impact-type turbine-behind exhaust device. The direct-impact-type turbine-behind exhaust device is provided with an exhaust volute of which the upper end face is provided with an opening; a partition plate is arranged in the manner of being perpendicular to the bottom face of the exhaust volute; the two opposite side wall faces of the exhaust volute are provided with pits concaved inwards, and the bottom face of each pit is provided with a through hole communicating with an internal cavity of the exhaust volute; a corrugated pipe is arranged in each pit, and each corrugated pipe protrudes out of the corresponding pit; the center of each corrugated pipe is provided with a diffused through hole communicating with the corresponding through hole, and a diffusion pipe which is in clearance fit with each diffused through hole is arranged in the diffused through hole; and the exhaust device is further provided with a divergent pipe connected to an opening of a supercharger turbine. According to the direct-impact-type turbine-behind exhaust device, the structural requirement that two exhaust systems are connected in a small space is met, it is guaranteed that the condition that air flow impacts the wall face at a high speed can not occur as the exhaust systems are low in resistance and flow speed, and a reliable guarantee is provided for the good performance of a diesel engine.
Description
technical field [0001] The invention belongs to the technical field of diesel engine exhaust, and mainly relates to a contra-type vortex rear exhaust device. Background technique [0002] For the installation of most vortex exhaust devices, the exhaust pipe and the bellows are firstly connected by flanges, and then the diffuser is installed on the exhaust port of the turbine, and then the bellows and the exhaust pipe are hoisted to the machine as a whole On the machine, the flange of the expander and the flange of the bellows are connected together after the whole is installed on the machine. The gradual expansion tube and bellows of this device protrude outside, and the structure is not compact enough to occupy the space of the diesel engine. At the same time, the installation is very cumbersome, and there are problems such as difficult positioning, fixing, and sealing of parts. bring great inconvenience. Contents of the invention [0003] In order to solve the above-me...
