CN203315877U - Air-dust separation device in dust discharging system - Google Patents

Abstract

The utility model discloses an air-dust separation device in a dust discharging system and relates to the technical field of dust discharge. The air-dust separation device comprises an outer shell and an inner cylinder, wherein the outer shell is connected with a dust discharging pipeline; the inner cylinder is arranged inside the outer shell; the bottom of the outer shell is communicated with a closed room; dust is blown into an outer cavity between the outer shell and the inner cylinder through a fan, and falls down under the action of gravity. Air continuously flows into the closed room, and indoor air flows from an inner cavity in the inner cylinder to the outside under the action of air pressure, so that air-dust separation is realized. The air-dust separation device has the advantages of simple structure and environmental friendliness; the air and the dust in the dusty air of the dust discharging system are quickly and effectively separated, so that the air flows to the outside, and the dust is precipitated and recycled; resources are saved.

Description

Gas and dust separating device in a kind of dust-exbaust system

Technical field

The utility model relates to the dust discharge technical field, relates in particular to the gas and dust separating device in a kind of dust-exbaust system.

Background technology

Often relate to the emission problem to dust in manufacturing process, the normal a kind of technology adopted is blower fan dust discharge method at present, thereby drive airflow by the blower fan high speed rotating and drive the mobile discharge of dust, dust directly is discharged in air and goes to cause great pollution and destruction to environment, and some dust granules can reclaim utilization again.

At present blower fan being driven to the dust collection technique of discharging is generally that discharge line is directly collected in a room of aligning; thereby this method collection efficiency is very poor to be had a large amount of dusts and extrudes room and air-flow and do not circulate and easily cause in discharge pipe reverse flowing of air flows to make blower fan to run well producing and can not carry out smoothly due to the air pressure reason; the method also had is to add that one deck filter screen is by Bas Discharged under the dust filter discharging the mouth of pipe, but dust too much easily stops up network interface and causes device damage shutdown etc. to make equally production normally to carry out.

The utility model content

Problem to be solved in the utility model is to provide a kind ofly can effectively separate the air of discharging in dust-exbaust system and the device of dust.

For the technical scheme that addresses the above problem the utility model and provide is:

Gas and dust separating device in a kind of dust-exbaust system, described device comprises the dust discharge pipeline, closed room, also comprise shell, inner core, shell is connected with the dust discharge pipeline, inner core is placed in enclosure, shell is connected in closed upper part with inner core, inner core communicates with the external world for upper and lower open cylindric top, outer casing bottom is communicated with a closed room, dust is blown to shell and the landing downwards together with air due to gravity and wind-force dust in outer chamber between inner core by the dust discharge pipeline by blower fan, because the room closed gas constantly flows to, in being subject in the air pressure application chamber, air rises extraneous by the inner chamber body flow direction of inner core inside, thereby reach gas dirt separating effect.

The utility model has the advantage of simple in structurely, can effectively separate fast dust-exbaust system has air and the dust in dirt gas, makes the recycling that precipitates of the extraneous dust of air flow, and environmental protection, economize on resources.

The accompanying drawing explanation

Fig. 1 is the gas and dust separating device schematic diagram in a kind of dust-exbaust system of the utility model.

The specific embodiment

Below in conjunction with accompanying drawing, the utility model is described in further details,

Gas and dust separating device in dust-exbaust system as a kind of as Fig. 1, described device comprises blower fan 1, the dust discharge pipeline, closed room 6, separator shell 5, inner core 3, shell 5 is connected with the dust discharge pipeline, inner core 3 is placed in shell 5 inside, shell 5 is connected to form outer chamber 4 with inner core 3 in closed upper part, inner core 3 is upper and lower open cylindric, inner core 3 tops communicate with the external world and form inner chamber body 2, shell 5 bottoms are communicated with a closed room, dust is blown to the outer chamber 4 between shell 5 and inner core 3 by the dust discharge pipeline by blower fan 1, due to gravity and the landing downwards together with air of wind-force dust, because room 6 closed gas constantly flow to, in being subject in the air pressure application chamber, air rises extraneous by inner chamber body 2 flow directions of inner core 3 inside, thereby reach gas dirt separating effect.

It will be appreciated by those skilled in the art that the above specific embodiment only illustrates, no matter be to change separating mechanism and dust discharge pipeline connected mode, or the conversion of some other equivalent constructions all falls in the utility model protection domain.

Claims (2)

1. the gas and dust separating device in a dust-exbaust system, dust discharge pipeline, closed room, characterized by further comprising shell, inner core, and described inner core is placed in enclosure.

2. the gas and dust separating device in a kind of dust-exbaust system according to claim 1, is characterized in that shell is connected in closed upper part with inner core, and inner core communicates with the external world for upper and lower open cylindric top.
