Description
Technical field
The present invention relates to a kind of shipping use for electric locomotive parts, specifically be a kind of use for electric locomotive air filtration unit.
Background technology
High speed development of national economy is had higher requirement to the development of transportation, in order to adapt to development and national economy, the railway freight transportation has dropped into bullet train, and telling of goods train moves the particularly bad weather in northwester sand ground district, the heart component of bullet train high-speed cruising is electric locomotive, air filtration unit is the critical component that guarantees the electric locomotive high-speed cruising, general in the market is the steel construction air filtration unit, filter efficiency has only about 30% under the same conditions, and crushing has reached about 200Pa.Clean and the replacement cycle weak point operating cost height.The consumption of chemical fibre felt or filtration sponge is big on the secondary filter simultaneously, because of discard processing causes environmental pollution.
Summary of the invention
At above deficiency, the invention provides a kind of use for electric locomotive air filtration unit, to the conscientious improvement of its filter, its filter efficiency is improved a lot, and crushing have only 80Pa.
In order to reach above purpose, the technical solution used in the present invention is: a kind of use for electric locomotive air filtration unit, comprise connecting box, disposal box, coarse filter, ventilating duct and fixed head, connecting box is connected with electric locomotive, ventilating duct is connected with the electric locomotive air-intake device, ventilating duct is arranged on the connecting box, and coarse filter is installed between two fixed heads, and connecting box and disposal box are installed in the upper and lower of fixed head respectively, it is characterized in that: described coarse filter comprises air deflector and filter, filter comprises middle part filter and lower filter, and two air deflector middle part filters and two lower filter are formed a coarse filter unit, and air deflector is on top, the middle part filter is at the middle part, and lower filter is in the bottom.
Because the present invention has adopted above technical scheme, its advantage is: the one, because the coarse filter unit adopts staggered air deflector and filter, can improve filter effect, and reduce crushing, be suitable for big traffic filtering, meet the speed increase in vehicle requirement; The 2nd since whole coarse filter to be connected case, fixed head, side plate and disposal box airtight, can further improve filter effect; The 3rd because disposal box adopts funnelform design, so that the eliminating of dust.In sum, air filtration unit good filtration effect of the present invention, crushing is low, and dust arrives can be cleared up a certain amount of the time automatically, helps to reduce labor intensity, and economizes on resources.

The specific embodiment
Embodiment one
As Fig. 1, shown in 2, a kind of use for electric locomotive air filtration unit of the present invention, comprise connecting box 1, disposal box 2, coarse filter 5, ventilating duct 3 and fixed head 4, connecting box 1 is connected with electric locomotive by contiguous block 7, and ventilating duct 3 is connected with the electric locomotive air-intake device, and ventilating duct 3 is arranged on the connecting box 1, coarse filter 5 is installed between two fixed heads 4, connecting box 1 and disposal box 2 are installed in the upper and lower of fixed head 4 respectively, and as shown in Figure 3, coarse filter 5 comprises air deflector 8 and filter, filter comprises middle part filter 9 and lower filter 10, two air deflector middle part filters and two lower filter are formed a coarse filter unit, and air deflector is on top, and the middle part filter is at the middle part, lower filter is in the bottom, air deflector, middle part filter and lower filter are staggered.There is side plate 6 the filter two sides, and side plate 6 is fixed on the fixed head, make coarse filter of the present invention four sides airtight, avoid entering of dust and assorted air-flow, thereby improve filter effect.
As shown in Figure 4, air deflector 8 structures in the coarse filter are that top is circular arc, the centre is two semicircles, two semicircles adopt little fillet excessive, and the diameter of top circular arc is greater than the diameter of middle two semicircles, and circular arc plays guide functions, semicircle plays shunting and guide functions, whole by the shunting of circular arc water conservancy diversion, the reduction crushing is suitable for big traffic filtering simultaneously.
As shown in Figure 5, the middle part filter adopts circle mid portion gap, and all wedge angles adopt and lead the mode of fillet, and dividing plate is left in the bottom.Air communication is crossed breach and is entered in the filter of middle part, enters lower filter with air-flow more after filtering.Bottom baffles plays baffle, shunting and guide functions, allows air-flow enter lower filter once more.
As shown in Figure 6, lower filter adopts the middle gap of circle, and all wedge angles parts are rounding all.Air-flow enters from breach, filters once more.
The operation principle of whole coarse filter is: when air passes through coarse filter, flow along the gap curve between each tube element, air deflector, the middle part filter, the air duct of lower filter inside have wide have narrow, so the speed of air-flow in filter just has the low height that has, dust (or raindrop) is when entering filter with air-flow, air velocity at channel restriction is higher, dust (or raindrop) obtains energy, air velocity is slowed down at the spacious place of passage, and each tube element produces trapping phenomena when adopting the rounding design to avoid air to flow through filter, influence flowing of air, thereby dust (or raindrop) breaks away from air communication under action of inertia crosses sewage draining exit 11 and enters disposal box, so repeatedly, dust in the air-flow and raindrop are separated.The dust of separating (or raindrop) is collected by disposal box, and thinner dust is adsorbed on the disposal box inwall, can be washed away by rainwater.
Embodiment two
With a kind of use for electric locomotive air filtration unit of embodiment one, its difference is: disposal box 2 four sides tilt as funnel-form, are convenient to the eliminating of dust, need not novel the dismounting with electric locomotive of basis just can be cleaned out dust.
In addition to the implementation, the present invention can also have other embodiments.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop in the protection domain of requirement of the present invention.
