Automatic air blowing and filtering system applied to air inlets of transportation tools

Abstract

The invention relates to an automatic air blowing and filtering system applied to air inlets of transportation tools. The automatic air blowing and filtering system comprises an air filtering frame, wherein an air-filtering air inlet is formed in one side of the air filtering frame; an air-filtering air outlet is formed in the other side of the air filtering frame; a middle flow guider is arrangedbetween the air-filtering air inlet and the air-filtering air outlet; air admission flow guide surfaces are arranged on two sides of the middle flow guider; the lower ends of two air admission flow guide surfaces are connected with a main air channel flow guide surface; an outside flow guide angle and an outside flow guide surface are arranged on the middle flow guider; a plurality of flow guiders are mounted in the air-filtering air inlet or the air-filtering air outlet in a transverse direction; the flow guiders are vane type flow guiders of curved-surface structures; gaps are formed amongthe plurality of flow guiders; an air inlet channel or an air outlet channel is formed between every two adjacent flow guiders; a main air channel is formed between the lower ends of the flow guidersand a filtering screen; the filtering screen is mounted in the air filtering frame along a length direction of the main air channel. According to the automatic air blowing and filtering system, air energy equipment does not need to be additionally arranged; the system is capable of automatically blowing the air by using the self-generated reverse airflow when the transportation tools run; meanwhile, the automatic air blowing and filtering system has the advantages of simple structure, no maintenance, convenience in mounting and use and excellent air blowing and filtering effect.

Description

technical field [0001] The invention belongs to the technical field of blowing air during the operation of rail transportation vehicles and road transportation vehicles, and in particular relates to an automatic air blowing and filtering system used for air inlets of transportation vehicles. Background technique [0002] In today's society, rail transportation mainly includes diesel locomotives, electric locomotives, EMUs, high-speed rail, passenger and truck carriages, light rails, subways and other transportation carriers, and road transportation mainly includes automobiles. Their normal operation needs to inhale a large amount of air to meet the needs of combustion of internal combustion engines, heat dissipation of electronic and mechanical components, and cooling of air conditioners and other facilities. With the inhalation of a large amount of air, there are a large number of floating objects such as dust, catkins, plant leaves, paper scraps, plastics, etc. in the air,...

AI Technical Summary

Problems solved by technology

[0009] The main reason for this problem is that most of the existing air intake filter dust removal devices adopt passive dust removal methods, and use filters such as filter screens, non-woven cotton, brown nets, and filter paper to absorb dust, catkins, and plants in the air. Dead leaves and other floating objects; however, as long as the filter is used to filter and absorb floating objects, the filter will inevitably be blocked as the floating objects gradually increase, resulting in a decrease in air intake. This is a persistent problem that cannot be overcome by traditional passive dust removal methods
