Abstract
The utility model relates to a special filter element for mining, belonging to the technical field of locomotive air filters; the special filter element mainly consists of a main filter element and an auxiliary filter element which respectively comprise an external screen, filter paper, an internal screen, an upper cover and a lower cover; composite fiber paper provided with dust removal filter layers on the surfaces is adopted as the filter paper; the folding angles of the filter paper are right angles and take on 'Pi' shapes; a wire-drawing strip is arranged at the welding part of the external screen; and the surfaces of the lower covers of the main filter element and the auxiliary filter element are respectively provided with a pull ring. The composite fiber paper provided with the dust removal filter layers on the surfaces is adopted, so that the effective filtration area of the filter paper is greatly enlarged; the folding angles of the filter paper are the right angles, so that the overlapping phenomenon is not caused between the two pieces of filter paper; the air filtration resistance is small so that the effective filtration area of the filter paper is enlarged, and the compared with the filtration accuracy of the common filter element, the filtering effect of the special filter element is improved by 50%; and furthermore, the wire-drawing net is arranged at the welding part of the external screen, and the pull rings which are convenient to operate are arranged on the lower covers, so that the convenience of the special filter element is greatly improved.
Description
Technical field
The utility model relates to the locomotive air filter technical field, relates in particular to a kind of mining single-purpose filtering element.Background technology
In engine operation process, need combustion air, in order to prevent that for example sand, dust and steam enter cylinder body and causes engine to damage airborne foreign material, usually configure cleaner before engine, filter core is the critical piece of cleaner, but under the ore deposit, air ambient dust density is large, and air humidity is large, and the filtration of filter core is had higher requirement.
the filter core of existing locomotive cleaner mainly is comprised of main filter core and auxiliary filter core, main filter core and auxiliary filter core comprise outer net, filter paper, Intranet, the up and down end cap, the effective filtration area of the filter paper of prior art is smaller, can not adapt to working environment requirement under the ore deposit, filter paper could use after need to fold simultaneously, but the filter paper of prior art as shown in Figure 4, be folded into the V font, angle folding is generally about 80 degree, this folded form causes between filter paper overlapping phenomenon can occur, the space is less, cause the air filtration resistance to increase, effectively filter area is also less, can not adapt to the requirement of environment under the ore deposit.
The edge of existing filter core outer net is generally by being welded, and has more burr at the weld of outer net, not only easily scratches operating personnel in installing and using process, and is simultaneously also not attractive in appearance; In the use procedure of this external filter core, need at regular intervals lower cover is unloaded down, the filter paper of the inside is changed, the lower cover smooth surface causes the lower cover dismounting very inconvenient.
The utility model content
The purpose of this utility model is to provide a kind of mining single-purpose filtering element, with solve the effective filtration area that prior art exists little, can not adapt to working environment under the ore deposit, and inconvenient problem with use.
The utility model mainly is comprised of main filter core and auxiliary filter core, main filter core and auxiliary filter core comprise outer net, filter paper, Intranet, upper cover and lower cover, solving the technical scheme that its technical problem adopts is that filter paper adopts the surface to be provided with the composite fibre paper of dust removel fiber layer, the angle folding of filter paper is the right angle, be several fonts, the weld of outer net arranges a wire drawing bar, and the lower cap surface of main filter core and auxiliary filter core arranges draw ring.
The upper cover of above-mentioned main filter core and auxiliary filter core arranges sealing ring.
The draw ring of above-mentioned main filter core lower cover is two, and symmetrical.
The beneficial effects of the utility model are:
1, effective filtration area is large, adapts to environment under the ore deposit.Adopt the surface to be provided with the composite fibre paper of dust removel fiber layer, greatly improved the effective filtration area of filter paper, the folded filter paper angle is the right angle, overlapping phenomenon can not occur between folded filter paper, and the air filtration resistance is less, has improved effective filter area.
2, easy to use.The outer net weld arranges the wire drawing net, has both prevented that operating personnel from being scratched by burr, has been improved the aesthetic property of filter core, and lower cover arranges the draw ring of handled easily simultaneously, is very easy to the dismounting of lower cover.
