Abstract
The utility model relates to a filter bag type dust collector. The filter bag type dust collector comprises a dust collection tank body; one end of the dust collection tank body is provided with air inlet flanges; a filter screen is arranged in the air inlet flanges; the air inlet flanges comprise a fixed air inlet flange and a movable air inlet flange; the fixed air inlet flange is fixedly connected with the dust collection tank body; the outside of the fixed air inlet flange is connected with the movable air inlet flange through fastening pieces; the filter screen is fixed between the fixed air inlet flange and the movable air inlet flange through the fastening pieces; and four annular arrays of the fastening pieces are provided. The filter bag type dust collector can filter dust-containing air at one time to ensure that large particles and dust cannot enter the dust collection tank body from the air inlet flanges, the direct impact on a filter bag can be reduced, the service life of the filter bag can be prolonged, the unnecessary halt time of the filter bag type dust collector can be reduced, and the dust collection efficiency is improved.
Description
Technical field
The utility model relates to a kind of deduster, relates in particular to a kind of filter bag type deduster, belongs to the device technique field that is used for filtering gas in the operation transportation.
Background technology
Deduster is the cleaner that dust is separated from flue gas, deduster has a lot of kinds, wherein the filter bag type deduster is more common a kind of in the deduster, as deduster that filter element was formed with filter bag, have rational in infrastructure, the advantages such as efficiency of dust collection is high, and energy-saving effect is remarkable, the dust, airborne dust that is widely used in the industries such as building materials, light industry, metallurgy, chemical industry process and production process in product reclaim.The filter bag type deduster generally includes dust-removing box, air inlet flange, air outlet flange and filter bag, air inlet flange, air outlet flange are separately positioned on the two ends of dust-removing box, filter bag is arranged in the dust-removing box, dusty gas enters in the dust-removing box from the air inlet flange, discharges from the air outlet flange after filter bag filters.When dusty gas enters dust-removing box from the air inlet flange; because throughput sudden enlargement; flow velocity reduces; larger particle in the dusty gas and dust are understood because collision and Gravitative Loads are separated; attenuating is to the impact of filter bag; if contain larger particle and dust when more; the phenomenon that has little time to separate can appear; impact to filter bag causes direct impact; reduce the service life of filter bag, needed the frequent filter bag, and extremely inconvenience of filter bag; cause filter bag type deduster unnecessary downtime, reduced efficiency of dust collection.
The utility model content
The utility model purpose is to provide a kind of can carry out coarse filtration to reduce the filter bag type deduster of the direct impact that filter bag is caused to dusty gas in order to overcome the deficiencies in the prior art.
For achieving the above object, the technical solution adopted in the utility model is: a kind of filter bag type deduster, comprise dust-removing box, and an end of described dust-removing box is provided with the air inlet flange, is provided with screen pack in the described air inlet flange.
Preferably, described air inlet flange comprises and decides air inlet flange and moving air inlet flange; Describedly decide the air inlet flange and be fixedly connected with dust-removing box; Describedly decide that the air inlet flange is outer to be connected with moving tuyere flange by securing member; Describedly decide to be provided with screen pack between air inlet flange and moving air inlet flange; Described screen pack is fixed on by securing member describedly to be decided between air inlet flange and moving air inlet flange.
Preferably, described securing member circular array is shown 4.
Because the utilization of technique scheme, the utility model compared with prior art has following advantages:
Filter bag type deduster of the present utility model; owing to being provided with screen pack in the air inlet flange; can once filter dusty gas; so that larger particle and dust can not enter in the dust-removing box from the air inlet flange; reduced the direct impact that filter bag is caused; prolong the service life of filter bag, reduced filter bag type deduster unnecessary downtime, improved efficiency of dust collection.
Description of drawings
Below in conjunction with accompanying drawing technical solutions of the utility model are described further:
Accompanying drawing 1 is the structural representation of filter bag type deduster of the present utility model;
Accompanying drawing 2 is the partial enlarged drawing of accompanying drawing 1;
Wherein: 1, dust-removing box; 2, decide the air inlet flange; 3, moving air inlet flange; 4, securing member; 5, screen pack.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and the specific embodiments.
Described in the utility model a kind of filter bag type deduster shown in accompanying drawing 1,2 comprises dust-removing box 1, and an end of described dust-removing box 1 is provided with the air inlet flange; Described air inlet flange comprises decides air inlet flange 2 and moving air inlet flange 3; Describedly decide air inlet flange 2 and be fixedly connected with dust-removing box 1; Describedly decide that air inlet flange 2 is outer to be connected with moving tuyere flange 3 by securing member 4; Describedly decide air inlet flange 2 and 3 of moving air inlet flanges are provided with screen pack 5; Described screen pack 5 is fixed on by securing member 4 describedly decides between air inlet flange 2 and moving air inlet flange 3.Screen pack 5 can once filter dusty gas, so that larger particle and dust can not enter in the dust-removing box 1 from the air inlet flange, dusty gas after once filtering is behind air inlet flange dust-removing box 1, wherein remaining relatively large particle and dust are understood because collision and Gravitative Loads are separated, reduced the direct impact that filter bag is caused, prolong the service life of filter bag, reduced filter bag type deduster unnecessary downtime, improved efficiency of dust collection; Simultaneously, when needing to change screen pack 5, screw off securing member 4, to move the air inlet flange and unload, change new screen pack 5 after, again with securing member 4 moving air inlet flange 3 with decide air inlet flange 2 and fix, convenient and swift, reduced the replacing time, again improved efficiency of dust collection.
Above-mentioned filter bag type deduster, general, described securing member 4 circular arraies are shown 4.
Below only be concrete exemplary applications of the present utility model, protection domain of the present utility model is not constituted any limitation.All employing equivalents or equivalence are replaced and the technical scheme of formation, all drop within the utility model rights protection scope.
