Abstract
The utility model discloses a dust hood which comprises a dust hood body with a hollow cavity. A gas inlet and a gas outlet communicating with the hollow cavity are arranged on the dust hood body. The dust hood is characterized in that the dust hood body comprises an expansion section and a constricted section, wherein the gas inlet is arranged on the bottom of the constricted section, and the gas outlet is arranged on the top of the expansion section. Since the dust hood body comprises an upper expansion section and a lower constricted section, gas containing dust accelerates instantly when passing through the constricted section. A low pressure area is formed near the high speed flowing gas, thereby generating strong attraction force to effectively capture dust. The dust hood is low in pressure loss and excellent in dust collecting effect.
Description
Technical field
The utility model belongs to field of mechanical technique, specifically a kind of dust gathering arrester.
Background technology
Dust gathering arrester is the control dust-contained airflow, collects a kind of device of dust that it is that the important component part in the interior dust pelletizing system is sent in the part.Dust gathering arrester mainly is used in the place, dirt source of the pipe network system of gathering dust, and namely produces the enclosed hood top of dirt pits.Be not to be with inspection door on the dust gathering arrester body, inspection door generally is located on the pipe network.Prior art is owing to adopt the centralized mode pipe network system of gathering dust longer, and the kinetic equation loss of system is large, and the dirt source is in gathers dust pipe network system foremost, the control of dust dynamics weakens, adopt this type dust gathering arrester, moment is improved the wind speed at place, dirt source, can effectively strengthen the capture dynamics of dust.
The utility model content
The purpose of this utility model is to provide the dust gathering arrester that a kind of dust collecting effect is good, the pressure loss is little.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of dust gathering arrester, comprise the dust gathering arrester body that an inside is cavity, the dust gathering arrester body is provided with gas feed and the gas vent that communicates with its inner chamber, it is characterized in that described dust gathering arrester body is divided into diffuser and contraction section two parts, described gas feed is arranged on the bottom of contraction section, and described gas vent is arranged on the top of diffuser.
Described diffuser is provided with inspection door.
Described gas outlet is provided with control valve.
Described gas feed place is set to horn mouth.
The beneficial effects of the utility model: the utility model dust gathering arrester body is set to the contraction section of bottom and the diffuser two parts on top, when dusty gas passes through the dust gathering arrester contraction section, the instantaneous increase of speed meeting, near swiftly flowing gas, can form low-pressure area, thereby produce powerful absorption affinity, with dust catching, this dust gathering arrester pressure loss is little, dust collecting effect good effectively.

Fig. 3 is the utility model top view.
Among the figure: 1, control valve, 2, dust gathering arrester dirt body, 3, inspection door, 4, gas feed, 5, gas vent, 6, diffuser, 7, contraction section.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Such as Fig. 1, Fig. 2 and Fig. 3.A kind of dust gathering arrester, comprise the dust gathering arrester body 2 that an inside is cavity, dust gathering arrester body 2 is provided with gas feed 4 and the gas vent 5 that communicates with its inner chamber, it is characterized in that described dust gathering arrester body 2 is divided into diffuser 6 and contraction section 7 two parts, described gas feed 4 is arranged on the bottom of contraction section 7, and described gas vent 5 is arranged on the top of diffuser 6.Described diffuser 6 is provided with inspection door 3.Be that described gas feed 4 places are set to horn mouth.
Dusty gas enters the contraction section 7 of dust gathering arrester body 2 from gas feed 4, because contraction section 7 is the diminishing cavitys that make progress, gas is in the instantaneous increase of speed meeting of contraction section 7, near swiftly flowing gas, can form low-pressure area, thereby produce powerful absorption affinity, when gas entered diffuser 6, gas velocity diminished suddenly, made being sucked away that dust in the dust gathering arrester cavity is more prone to.Dust in the dust gathering arrester cavity is gone out from gas vent 5, and gas vent 5 places are provided with control valve 1, is used for the adjustments of gas discharge.
Claims (4)
1. dust gathering arrester, comprise the dust gathering arrester body (2) that an inside is cavity, dust gathering arrester body (2) is provided with gas feed (4) and the gas vent (5) that communicates with its inner chamber, it is characterized in that described dust gathering arrester body (2) is divided into diffuser (6) and contraction section (7) two parts, described gas feed (4) is arranged on the bottom of contraction section (7), and described gas vent (5) is arranged on the top of diffuser (6).
2. dust gathering arrester according to claim 1 is characterized in that described diffuser (6) is provided with inspection door (3).
3. dust gathering arrester according to claim 1 is characterized in that described gas vent (5) locates to be provided with control valve (1).
