Abstract
Description
Technical Field
[0001] The utility model relates to the field of purifiers, in particular to an air inlet end optimization device for a purifier. Background Art
[0002] With the implementation of the National VI emission regulations for motor vehicles, the requirements for the uniformity of the flow rate of the purifier carrier are getting higher and higher. For the intake end cover structure, the intake pipe extends into the end cover for a long time. If there is no structure to weld it, its strength is not enough and it is easy to fall off; the outlet of the intake straight pipe is close to the carrier. If there is no device to guide and evacuate the airflow, the gas will be concentrated and sprayed to the center of the carrier end face. The airflow speed around the carrier is low, resulting in poor overall speed uniformity and reduced catalyst utilization.
[0003] For example, the utility model disclosed in the publication (announcement) number: CN216767525U discloses a purifier air inlet end optimization device, including a square flange, an air inlet straight pipe, an air inlet end cover, a spoiler, a carrier and a cylinder; one end of the air inlet straight pipe is the air inlet end, and the other end is the air outlet end; the square flange is fixed to the air inlet end of the air inlet straight pipe; an arc-shaped reinforcement plate is welded on the air outlet end of the air inlet straight pipe, and the outer edge of the arc-shaped reinforcement plate is welded to the inner wall of the air inlet end cover; the air inlet end cover is a trumpet-shaped structure, and the small end of the air inlet end cover is welded to the outer wall of the air inlet straight pipe; the spoiler is fixed inside the air inlet end cover; a number of circular through holes are evenly distributed at the center of the spoiler, and the carrier is arranged in the cylinder. The utility model diffuses, swirls, and disperses the gas flow, improves the uniformity of the air flow, avoids the air flow directly spraying the carrier end face causing the local temperature to be too high, and the carrier erosion occurs; strengthens the strength of the connection between the air inlet straight pipe and the air inlet end cover to avoid falling off.
[0004] The device of the above utility model is provided with a spoiler to improve the uniformity of airflow flow, to avoid the airflow directly spraying on the end face of the carrier causing local excessive temperature and carrier erosion. However, in actual use, due to the influence of boundary requirements, the airflow direction on the air intake side is often eccentric and cannot be evenly distributed, which leads to certain limitations of the above device and cannot ensure the uniformity of airflow flow at one end of the purifier carrier.

[0020] In this embodiment, the cross-section of the connecting tube 5 is a trapezoidal structure, and the top and bottom ends of the connecting tube 5 are respectively welded and fixed to the outer side of the bottom end of the air intake straight pipe 1 and the inner wall of the air intake end cover 2, and the optimization component 6 includes an air equalizing plate 61 whose edge is welded and fixed to the inner wall of the bottom end of the air intake end cover 2, and the air equalizing plate 61 is penetrated with a plurality of air equalizing holes 610 in the vertical direction, and a connecting rod 62 is provided on the side of the air equalizing plate 61 close to the air intake straight pipe 1, and the two ends of the connecting rod 62 are respectively welded and fixed to the inner wall of the air intake end cover 2, and a rotating shaft 63 is slidingly penetrated at the center position of the air equalizing plate 61 and the connecting rod 62, and an air equalizing fan 64 is fixedly installed on the rotating shaft 63 on the side of the connecting rod 62 away from the air equalizing plate 61, and one end of the rotating shaft 63 is fixedly connected to a cleaning block 65 arranged in the horizontal direction in contact with the top end of the air equalizing plate 61, and a cleaning brush 66 is fixedly provided at the bottom end of the cleaning block 65.
[0021] Furthermore, an air intake side of the air intake straight pipe 1 is fixedly installed with external components through a flange, and an air equalizing fan 64 is fixedly installed on the top of a rotating shaft 63 rotatably connected to the air equalizing plate 61 and the connecting rod 62. Therefore, when the airflow in the air intake straight pipe 1 enters the air intake end cover 2 from the bottom end of the air intake straight pipe 1, the airflow drives the air equalizing fan 64 to rotate, thereby stirring and fanning the airflow entering the air intake end cover 2, and combining with the multiple air equalizing holes 610 opened in the vertical direction through the air equalizing plate 61 to equalize the air, so that the airflow is fully dispersed when it enters one end of the carrier 4 in the mounting tube 3 from the bottom end of the air intake end cover 2, and the airflow velocity is more uniform, which effectively avoids the airflow distribution at one end of the carrier 4 caused by the eccentric airflow direction on the air intake side of the air intake straight pipe 1 due to the influence of boundary requirements.
