Abstract
The utility model relates to an industrial cyclone dust remover. A partition board between the upper cover of a cylinder and the cylinder is downwards connected with an annular shielding case. At least one small cyclone is arranged in the shielding case. The structure of the small cyclones is the same with the structure of a single stage dust remover, but the size of the small cyclones is reduced. The inlets of the small cyclones are communicated with the inner hollow chamber of the shielding case, the outlets of the small cyclones are communicated with the outlets of the upper cover via passing through the partition board, dust discharge pipes connected with the lower ends of the lower cones of the small cyclones are passed through the side wall of the lower cone at the lower end of the cylinder, and the outlets of the small cyclones are positioned in a dust collecting funnel together with the small dust discharge pipe of the cylinder.
Description
The utility model relates to a kind of industrial cyclone dust collectors.
Existing cyclone dust collectors are the single-stage monomer, and it is made up of cylindrical shell, lower cone, under fan action by carrying out centrifugal dust-removing into and out of the air port on the cylindrical shell.Because it has only a centrifugal casing cylinder, thus can only the single-stage dedusting, efficiency of dust collection is low, and weak effect can also recycle the meal dirt about 60 orders, just can't separate recovery for the dust more than 120 orders, can only enter atmosphere from outlet.
The purpose of this utility model is exactly in order to address the above problem, and a kind of efficiency of dust collection height, effective dual stage cyclone deduster are provided.
Technical solution of the present utility model:
A kind of dual stage cyclone deduster, it includes cylindrical shell (1) and lower cone (2), cylindrical shell (1) top one side is provided with volute type import (3), have outlet (5) on the loam cake (4) of cylindrical shell (1) upper end, be connected with little ash-unloading tube (6) in lower cone (2) lower end, it is characterized in that on the loam cake (4) of cylindrical shell (1) and the dividing plate (7) between the cylindrical shell (1), being connected with annular isolation cover (8) downwards, its external diameter is less than the internal diameter of import (3) volute body, its height is greater than the volute body height, and be positioned at volute body, in annular isolation cover (8), be provided with whirly (9) at least, the structure and the single-stage deduster structure of this whirly (9) are identical, just size is dwindled, the import of each whirly (9) all is communicated with the internal cavity of cage (8), the outlet (5) that their outlet all passes on the loam cake (4) of dividing plate (7) and cylindrical shell (1) is communicated with, the ash-unloading tube (10) that their lower cone lower ends connect all passes from lower cone (2) sidewall of cylindrical shell (1) lower end, little ash-unloading tube (6) together with cylindrical shell (1) lower cone (2), its outlet all is positioned at ash bucket (11), and is provided with shutter unloading valve (12) in ash bucket (11) lower end.
The utility model adopts whirlwind of different-diameter to carry out series and parallel composition dual stage cyclone deduster first, the deduster that is original structure is the primary dust removing device, a plurality of whirly are formed secondary ash collector, between the I and II deduster, cage is set, reaches the purpose of two-stage tandem, and the I and II deduster is integrated in one, form dual stage cyclone deduster group, thereby improved classification efficiency, overcome the secondary eddy flow, the dust of collection that secondary ash collector is pounced on enters ash bucket respectively.The utility model novel structure, compactness, floor space is little, and cost of equipment is low, and is easy to use, and the efficiency of dust collection height can reach more than 95%, all can effectively handle the dust more than 240 orders, and effect is very desirable.The utility model can be widely used in industries such as machining, metallurgical building materials, mine excavation, refractory material, coal, chemical industry, grain, cement and electric power.
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the A-A sectional drawing of Fig. 1.
As Fig. 1,2, the utility model is preferably in three whirly (9) is set in the annular isolation cover (8), and they are evenly to arrange.
During the utility model work, locate the machine of giving a dinner for a visitor from afar, carry out work by the negative pressure that blower fan produces in the outlet (5) of cylindrical shell (1) loam cake (4).After dusty gas tangentially enters cylindrical shell (1) from volute type import (3), between cylindrical shell (1) inwall and cage (8), do top-down rotatablely moving (outer eddy flow), dusty gas produces very big centrifugal force in rotary course, because the effect of inertia of grit, when grit with after barrel contacts, just lose inertia force and fall along wall, separated from the gas, dust enters in the ash bucket (11) from little ash-unloading tube (6) through lower cone (2).When the outer eddy flow of rotation decline reaches lower cone (2), just begin to rotate up, air-flow bottom-up (interior eddy flow) for the helical movement, the import that enters each whirly (9) along cage (8) inwall, the separated once more ash-unloading tube (10) from each whirly (9) of grit enters ash bucket (11), and purified gas is finally discharged from outlet (5).
The cage (8) that the utility model is provided with is isolated two-step filter, cage (8) constitutes the primary dust removing device with cylindrical shell (1), and cage (8) is equivalent to the blast pipe of primary dust removing device again, and its underpart is made and shunk shape, reduce drag losses, reduced energy loss.Gas after being cleaned enters whirly (9) deduster again, carries out final dusting, thereby realizes two-stage series connection, improves efficiency of dust collection.
The utility model adopts fixed ash bucket (11), and it keeps airtight in the ash discharge process, reduces air leak rate of air curtain, prevents that the interior rotational gas flow in the cylindrical shell (1) from collecting entrainmenting of dust to pouncing on, guarantees dust removing effects.
