Description

Technical Field

[0001] The utility model relates to the technical field of locomotive filtration, and more specifically, to a locomotive side wall filter with a filter net. Background Art

[0002] A locomotive side wall filter is an air filtration device installed on the side wall of a locomotive. Its main function is to filter the air entering the locomotive interior, removing impurities such as dust and particulate matter to protect the normal operation of the locomotive engine and other equipment. The locomotive side wall filter is an important part of the locomotive air management system, ensuring the reliable operation of the locomotive under various environmental conditions.

[0003] For example, Chinese Patent No. 201320782685.0 discloses an air filter device for diesel locomotives. A steel wire mesh and a straight-through cyclone filter are installed on the intake valve assembly. The side of the intake valve assembly is installed on the side wall body through an external hinge. Inner and outer support frames fix a bag filter in the box body, which has excellent filtering performance.

[0004] However, the above-mentioned air filter device for diesel locomotives still has the following deficiencies: During the willow catkin season, the amount of willow catkins in the air increases. When preventing willow catkins from entering the locomotive, when using a combination of a steel wire mesh, a straight-through cyclone filter and a bag filter, willow catkins may quickly clog the filter, especially the bag filter, resulting in poor air circulation. Furthermore, it is necessary to clean and replace the filter more frequently, increasing the maintenance workload.

[0005] For the problems in the related art, no effective solution has been proposed yet. Summary of the Utility Model

[0006] In view of the problems in the related art, the present utility model proposes a locomotive side wall filter with a filter net to overcome the above-mentioned technical problems existing in the prior related art.

The V-shaped filter nets are connected to the anti-willow-catkin components through fastening components; at both ends of the locomotive side wall connecting frame, there are provided a number of locomotive side wall connecting holes.

[0009] Furthermore, in order to capture willow catkins, the anti-willow-catkin components include a frame provided on one side of the locomotive side wall connecting frame. Anti-willow-catkin filter nets are provided on the side wall of the frame and at one end away from the locomotive side wall connecting frame; a sealing gasket is provided between the frame and the locomotive side wall connecting frame and at the edge of the frame.

[0010] Further, in order to achieve a ventilation effect and effectively filter sand and dust impurities, a connecting plate is provided at the bottom end of the V-shaped filter net. The connecting plate is connected to the connecting frame of the locomotive side wall through a first bolt; fixing blocks are provided at both ends of the V-shaped filter net, and threaded holes are opened in the fixing blocks.

[0011] Further, in order to connect the anti-catkin component to the V-shaped filter net, the fastening component includes through holes opened on the side wall of the frame. A second bolt is arranged in the through holes, and one end of the second bolt is connected to the threaded hole; the through holes are arranged in an oblong shape, and the number of the through holes is greater than or equal to two.

[0012] The beneficial effects of the present utility model are as follows:
