Abstract
The utility model discloses an air inlet device of a bag-type dust collector, belonging to the technical field of the bag-type dust collector. The air inlet device of the bag-type dust collector is characterized by comprising an outer cylinder, wherein an inner cylinder is arranged in the outer cylinder, the outer cylinder and the inner cylinder are both annular cylinder bodies and are in sealing connection, an air inlet is arranged at one side of the outer cylinder, and the air inlet is arranged at the position which is tangent to the outer circumference of the outer cylinder. The air inlet device of the bag-type dust collector, disclosed by the utility model, adopts the annular air inletting at the lower part and has a pre-processing function, larger particles in dust-containing gas can be removed in an annular channel, the air inletting is in a uniform distribution mode at the periphery of the lower part of a filter bag, the air vent area is enlarged, the air speed is lowered, the impact from the dust-containing gas to the filter bag can be reduced, and the filtering efficiency and the service life of the filter bag are increased.
Description
Technical field:
The utility model relates to a kind of air-intake device of sack cleaner, belongs to the sack cleaner technical field.
Background technology
In commercial production, processes such as material fragmentation, transhipment produce a large amount of dusty gases; Along with people's is to the improve of environmental requirement, and discharge standard will be more and more stricter.Performance to deduster proposes higher requirement.
Defectives such as sack cleaner is widely used in every profession and trade, but exists air-flow directly to impact filter bag, influences life-span of the filter bag, and the air inlet skewness causes wind speed low excessively, and dust collector efficiency is lower.
The utility model content:
To the problem that prior art exists, the purpose of the utility model patent provides the pretreated air-intake device that is uniformly distributed with of a kind of band air, makes sack cleaner be suitable for the higher environment of dust content.
The technical scheme that the utility model is taked is:
A kind of inlet duct of sack cleaner is characterized in that: comprise urceolus, inner tube installation is on urceolus; Urceolus and inner core are all circular cylinder; Be tightly connected between inner core and the urceolus, offer air inlet in a side of urceolus, air inlet is opened in and the tangent place of urceolus excircle.
Further be provided with and be:
Straight shape or spirality are arranged in the bottom of inner core.
Be provided with awl bucket and ash discharging hole in the bottom of urceolus.
In inner core, be provided with some evenly distributed filter bags that are, air outlet is arranged at the top of inner core.
The beneficial effect of the utility model is following:
The utility model adopts bottom hoop air intake, has the preliminary treatment effect.The dusty gas tangential gets into annular passage; This part is the equal of the preprocessing part of deduster, and through the centrifugation bulky grain, airflow direction is consistent with the solid particles sediment direction simultaneously; Inner core bottom and outer cylinder body cone leave the gap, and pretreated bulky grain glides along barrel wall and gets into the awl bucket.Gas gets into the filter bag bottom around the bottom of circular passage, because of from around get into, the urceolus diameter is bigger in addition, gas can evenly get into filtering area to hang down flow velocity, help improving filter bag efficient and service life.
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is described further.
Description of drawings:
Fig. 1 is the structural representation of the utility model device.
Fig. 2 is the vertical view of Fig. 1.
The specific embodiment:
As shown in Figure 1, the inlet duct of the sack cleaner of the utility model comprises urceolus 2; Inner core 3 is installed on the urceolus 2, and urceolus 2 is all circular cylinder with inner core 3, is tightly connected between inner core 3 and the urceolus 2; Side at urceolus 2 offers air inlet 1, and in the present embodiment, air inlet 1 is opened in and the tangent place of urceolus 2 excircles; Be provided with awl bucket 6 and ash discharging hole 7 in the bottom of urceolus 2, in inner core 3, be provided with some evenly distributed filter bags 4 that are, air outlet 5 is arranged at the top of inner core 3.In the present embodiment, straight shape is arranged in the bottom of inner core 3, certainly, and also can be according to air-flow distribution design spirality or other shapes.
The operation principle of the utility model is following: during work, the high concentration dusty gas gets into the annular passage of being made up of urceolus 2 and inner core 3 through the air inlet of tangential direction 1, in annular passage, struggles against 6 because the action of centrifugal force bulky grain falls into awl along the inwall of urceolus 2; Around the bottom of inner core 3, get into filter bag 4 districts through pretreated dusty gas, the clean gas after the filtration is from exhaust outlet 5 dischargings; The granule that bulky grain and filter bag filter gets into awl bucket 6, regularly arranges from ash discharging hole 7 and unloads when reaching a certain amount of back.
