Abstract
The utility model which is a dustproof and breathable screen window used on the train, belongs to dustproof screen window of train capable of bearing heavy airflow pressure. To make the window can be dustproof and breathable on the condition of heavy wind and large airflow, the utility model adopts a plurality of sand-dust filter screens and a deformation resistant fence is disposed on both surfaces of the filter screens, furthermore external and internal frames are arranged, which respectively have light penetration filter screen and light preventing filter screen with precise filtration. The external frame of dustproof and light penetration can be chosen according to the size of sand and dust, or the external and internal frames of dustproof and light prevent can be overlapped to use. The utility model has the advantage that it is dustproof as well as breathable on the condition of heavy wind and large airflow, and two dustproof modes are available to choose according to the size of dust.
Description
Technical field
The utility model belongs to vehicle window technical field, particularly train and the dustproof screen window that can bear than air flow pressure.
Background technology
The window in existing train, automobile, house mainly contains two big functions: transparent and ventilative.But the train of running at high speed for a long time in the desert for preventing dust storm, as cuts out window, and the window transparent functional can be lighted with electric light alternative, but the window airing function is difficult to solve.
Summary of the invention
The purpose of this utility model provides a kind of can preventing dust, and the screen window that can breathe freely again is specially adapted to the train window in the desert of travelling than air flow pressure.
Design of the present utility model is: with the very low stainless steel filtering net of order number, or with the very low stainless steel filtering net of order number and non-woven cotton layer in conjunction with preventing that the outer sand and dust of train from entering in the train.The interior outside window stream pressure difference of train in owing to travel is big, and the stream pressure difference changes also greatly, only with stainless steel filtering net with the non-woven cotton layer is very easy is damaged by air-flow, thus between stainless steel filtering net and non-woven cotton layer and two-layer outside all be provided with to reinforce and prevent that air-flow from damaging the fence of stainless steel filtering net and non-woven cotton layer.For preventing can to clash into stainless steel filtering net by the grain stone greatly, damage stainless steel filtering net, in the inner face or the outside of stainless steel filtering net, perhaps establish the husky net of the bigger stainless steel of order number in the inner face and the outside of stainless steel filtering net.
Stainless steel filtering net is with 20-40 purpose filter screen 3.Select for use the 20-40 mesh filter screen of antistatic preferably better.
The stainless steel gauze is with 80-120 purpose gauze 5.
The non-woven cotton layer is to be the non-woven cotton of 2-4 millimeters thick with nature thickness, and its unit weight is 0.25 kilogram/square metre comparatively suitable.
Structure of the present utility model is: the dustproof screen window of train, comprise outer rim 1, and outer rim 1 is provided with the setting that is connected with the train window, as fastener, screw etc.It is characterized in that: be provided with 20-40 purpose filter screen 3 in the outer rim 1, the two sides of 20-40 purpose filter screen 3 is respectively equipped with fence 4, and 20-40 purpose filter screen 3 is close to the fence 4 on two sides, prevents that air-flow from making 20-40 purpose filter screen 3 reciprocal fails in tension; Fixedly connected with outer rim 1 in the edge of 20-40 purpose filter screen 3 and fence 4.When outer rim 1 with after the train window is connected, 20-40 purpose filter screen 3 and fence 4 also just are fixed on the train window, prevent to enter in the train greater than 20-40 order sand and dust.
The steel wire of 20-40 purpose filter screen 3 is too thin, and anti-air-flow and impact that greatly can the grain sandstone are relatively poor, are provided with 80-120 purpose gauze 5 so certain fence 4 of being close at 20-40 purpose filter screen 3 is close to again, is provided with fence 4 again at the skin of 80-120 purpose gauze 5; Fixedly connected with outer rim 1 in the edge of 80-120 purpose gauze 5 and fence 4.For further gaining in strength, the two sides fence of being close at 20-40 purpose filter screen 3 was close to again and is provided with 80-120 purpose gauze 5 in 4 minutes, was provided with fence 4 again at the skin of 80-120 purpose gauze 5; Fixedly connected with outer rim 1 in the edge of 80-120 purpose gauze 5 and fence 4.
For to refiltering of entering less than 20-40 purpose sand and dust, be connected with rim 5 at the inner edge of outer rim 1, be provided with the non-woven cotton layer 6 that one deck can be breathed freely in the rim 5; Non-woven cotton layer 6 one side are close to the fence 4 of 80-120 purpose gauze 5; Non-woven cotton layer 6 another side also are provided with fence 4, and both are close to.Non-woven cotton layer 6 is irregular gas passages, and is better to tiny sand and dust filter effect.
Outer rim 1 is provided with mutual clamping or other device that conveniently is connected and discharges with rim 2, at sand and dust hour, can remove rim 2, without non-woven cotton layer 6 filtering gas, only surplus 20-40 purpose filter screen 3, or 20-40 purpose filter screen 3 and 80-120 purpose gauze 5, breathe freely like this and go back light-permeable, when sand and dust are too big, can load onto rim 2, increase non-woven cotton layer 6 and filter sand and dust gas.The light transmission of non-woven cotton layer 6 is bad, and available electric light is to the train intraoral illumination.
Advantage of the present utility model: be applicable to that the train window that travels is ventilative in the bigger environment of sand and dust, or ventilative and printing opacity usefulness, air flow pressure can not damage the material that filters usefulness, as stainless steel filtering net and non-woven cotton layer.The usefulness that the utility model also can be used for having the factory building of strong wind, air flow to filter sand and dust.It is not high to have solved filter screen intensity, can not be used for strong wind, air flow problem of environment.
