Embodiment Construction

[0029] The following will be combined with Figure 1 to Figure 8 The present invention is described in detail, and the technical solutions in the embodiments of the present invention are clearly and completely described. Apparently, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0030] It should be noted that when a component is said to be "fixed" to another component, it can be directly on the other component or there can also be an intervening component. When a component is said to be "connected" to another component, it may be directly connected to the other component or there may be intervening components at the same time. When a component is said to be "set on" another component, it may be set directly on th...

Abstract

The invention relates to the technical field of rail vehicles, in particular to a mechanical waste discharge device for rail vehicles, which includes a casing, sound-absorbing cotton is bonded around the inner wall of the casing, and a support is installed at the center of the inner wall of the bottom of the casing through bolts. The housing is welded with baffles on both sides of the inner wall close to the support seat. Beneficial effects of the present invention The top holding groove enables the top holding seat to be better bonded to the outer wall of the fan, improving the stability of the fan during operation. The top holding seat has a certain shock absorption effect on the fan through the action of the spring. The fan plays a very good protective role, thereby prolonging the service life of the fan. The sound insulation lining makes the fan reduce the noise generated by the air flow impacting the air duct when the fan draws air through the air inlet, and the sound-absorbing cotton further reduces the noise generated by the fan when it is working. Noise, provide passengers with a quiet environment, and improve the comfort of passengers when riding rail vehicles.

Description

technical field [0001] The invention relates to the technical field of rail vehicles, in particular to a mechanical waste discharge device for rail vehicles. Background technique [0002] In rail vehicles, each car is generally equipped with one or two air-conditioning units, and each air-conditioning unit adopts a unit structure or a split structure; The air outlet is connected, the air supply duct and the air supply outlet are used to supply air to the cabin, and the return air in the cabin is sent back to the air conditioner through the return air duct for recycling; the air conditioning unit communicates with the outside of the vehicle through the fresh air outlet to Deliver fresh air in the compartment to ensure the freshness of the air in the compartment. While delivering fresh air to the compartment, part of the exhaust gas is discharged out of the compartment through the exhaust device to ensure a certain positive pressure in the compartment to improve the comfort in...
