Problems solved by technology

However, in the above-mentioned filter, especially in the filter element part where the circumferential wall of the exhaust lumen is located, when the air passes through the filter element part, it will be directly discharged from the exhaust lumen to the exhaust passage, and the flow stroke is relatively short. , the residual moisture in the air will not condense and fall again, and will eventually enter the exhaust passage, resulting in the air filtered by the filter still containing more moisture, which is harmful to the braking system and wind system of rail vehicles make an impact

specific Embodiment 1

[0037] The air filter in the present embodiment is the air filter that rail vehicle is used, as figure 1 and figure 2 As shown, the air filter includes an upper casing 1, and the upper casing 1 is provided with an air inlet passage 13 and an air outlet passage 12 isolated from each other. In this embodiment, the inlet of the air inlet passage 13 and the outlet of the air outlet passage 12 are located on the upper The same side of the shell is very convenient for docking installation with valves and other structures. Depend on figure 1 It can be seen that the inlet is located below the outlet. Both the air inlet channel 13 and the air outlet channel 12 include a transverse section and a vertical section, and the transverse section of the air inlet channel is located below the transverse section of the air outlet channel. The vertical section of the air intake channel is an annular channel, and the vertical section of the air intake channel and the vertical section of the ai...

specific Embodiment 2

[0045] Such as image 3 As shown, the main difference from the above embodiment is that in this embodiment, the filter hole is not provided at the bottom of the barrel of the filter element 1, and only the filter hole 2 is opened on the barrel wall of the filter element 1, and there is an exhaust pipe cavity in the filter element 1. , a condensation guide pipe 3 is arranged in the exhaust pipe cavity, the air enters the lower end inlet of the condensation guide pipe 3 after passing through the filter hole 2, and then is discharged from the upper end outlet of the condensation guide pipe 3.

[0046] The outer peripheral surface of the condensation guide pipe is used to guide the air at the wall of the filter element barrel into the lower opening of the condensation guide pipe to form a guide outer peripheral surface. The lower end opening of the condensation guide pipe forms an air inlet, and the upper end opening forms an exhaust port. .

[0047] In this embodiment, "up" and ...

Abstract

The invention relates to an air filtering unit, a railway vehicle and an air filter thereof and aims at improving a filtering effect on moisture in air. The air filter for the railway vehicle comprises a shell body, wherein an air feeding channel and an air exhausting channel are arranged on the shell body, a filter core communicated with the air feeding channel is arranged in the shell body, an air exhausting pipe cavity extending in the axial direction is arranged in the filter core, condensing flow guiding pipe is arranged in the air exhausting pipe cavity, the condensing flow guiding pipecomprises an air exhausting opening which is in sealed connection with the air exhausting channel, the condensing flow guiding pipe further comprises an air inlet which extends into the air exhaustingpipe cavity in the axial direction, and the condensing flow guiding pipe further comprises a guiding peripheral face which can guide filtered air to the air inlet and make the air flow to the air exhausting opening from the condensing flow guiding pipe. According to the air filter disclosed by the invention, a flowing journey of air flowing out of a filtering material is increased; in a longer flowing journey, the air can be filtered many times, and moisture can be condensed; thus, the moisture in the air is reduced, and a filtering effect of the filter on the moisture is improved.

Description

technical field [0001] The invention relates to a gas filter unit, a rail vehicle and its air filter. Background technique [0002] Rail vehicles include an air compressor and an air pipeline system connected to the air compressor. The gas output from the air compressor enters the air pipeline system, but the compressed air discharged from the air compressor contains oil, water, metal impurities, and dust Particles, etc., will cause water freezing and corrosion of the air pipeline system, and more seriously, it will cause failure of the braking system and the air system. Therefore, it is necessary to filter the compressed air discharged from the air compressor to prevent the above situation from happening. [0003] A utility model patent with the authorized announcement number CN206381763U discloses a water-based air filter. The filter includes a shell, which is provided with an air intake channel and an exhaust channel. The shell is provided with a water storage cup. A fi...
