Description
Technical field
The invention belongs to field of food producing technology, and in particular to the dust suction of one of flue gas ash removal technical field
Cover.
Background technique
Currently, soybean protein isolate, enzymolysis protein are the soybean proteins of protein content > 90%.Typically production technology is
Alkali extraction-acid precipitation, the albumen powder produced after spray drying enter packaging system, just need in vibrating screen feed opening using dust hood
Carry out packaging dedusting.
And dust hood is in forward position in dust pelletizing system, currently, logical using negative pressure exhausting in common dust pelletizing system
It crosses dust hood and takes away dust, i.e., mainly by blower in the dust excluding hood of the patterns such as umbrella shape, rectangular, cause certain air-breathing speed
And effectively the dust generated in production process and pernicious gas are siphoned away, and achieve the purpose that dust cleaning by processing.
Dedusting main pipeline wind-force is stronger, declines since dust excluding hood opens wide wind-force when wind-force reaches dedusting shroud rim, pick-up performance also differs
Larger, if not enhancing main pipeline wind-force for serious influence dust removing effects, dedusting is not achieved ideal effect or must need to increase
Add main pipeline wind-force, can be only achieved dust removing effects, in this way increase energy consumption, improves cost.
Summary of the invention
For this purpose, the dust excluding hood being capable of processed soybeans albumen packaging production completely the object of the present invention is to provide a kind of dust excluding hood
Raw dust does not cause any adverse effect to environment, while can also save energy consumption.
A kind of dust hood, the fixed company of feeder pipe and the lesser side of feeder pipe sectional area including the trapezoidal setting in section
The interior cover connect, the trapezoidal setting in the section of interior cover are respectively arranged with outer outlet body in the two sides of interior cover and feeder pipe, outside
The section of cover is arranged in quadrangle and two sides therein are fixed with interior cover and feeder pipe respectively；
The interior cover is provided with suction hole, and air intake duct, air intake duct and one are provided between the interior cover and outer outlet body
Escape pipe is connected to, and is provided with negative-pressure air fan in escape pipe.
Further,
It is fully welded between the air intake duct and feeder pipe by argon arc welding.
Further,
Cover is fully welded with feeder pipe and air intake duct by argon arc welding respectively in the equipment.
Further,
Using interruption spot welding between the outer outlet body and interior cover, it is interrupted distance 30--50mm.
Further,
Suction hole total sectional area on the air intake duct is not more than the sectional area 70% of escape pipe.
Further,
Spacing 5mm in gap between outer outlet body and interior cover.
Other features and advantages of the present invention will be illustrated in the following description, also, partly becomes from specification
It obtains it is clear that understand through the implementation of the invention.The objectives and other advantages of the invention can be by written explanation
Specifically noted structure is achieved and obtained in book, claims and attached drawing.
Below by drawings and examples, technical scheme of the present invention will be described in further detail.
Detailed description of the invention
Attached drawing is used to provide further understanding of the present invention, and constitutes part of specification, with reality of the invention
It applies example to be used to explain the present invention together, not be construed as limiting the invention.In the accompanying drawings:
Fig. 1 is the structural schematic diagram of dust hood.
1, feeder pipe；2, dust cover；3, air intake duct；4, escape pipe；5, outer outlet body；6, interior cover.
Specific embodiment
Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings, it should be understood that preferred reality described herein
Apply example only for the purpose of illustrating and explaining the present invention and is not intended to limit the present invention.
The embodiment of the invention provides a kind of dust hood, its structural schematic diagram as shown in Figure 1, including the trapezoidal setting in section
Feeder pipe 1, the interior cover 6 that is fixedly connected with the lesser side of 1 sectional area of feeder pipe, the trapezoidal setting in section of interior cover 6,
Outer outlet body 5 is respectively arranged in the two sides of interior cover 6 and feeder pipe 1, and the section of outer outlet body 5 is arranged and therein in quadrangle
Two sides are fixed with interior cover 6 and feeder pipe 1 respectively.In the manufacturing process of the dust hood, dust hood is integrally used
2.0mm, the production of 304 stainless steel materials, all weld seams must be using being fully welded, and face of weld is smooth, no dead angle.
Interior cover 6 is provided with suction hole, preferably takes 11 row's suction holes on interior cover 6, every 7 hole of row, aperture from it is interior outward
It is gradually increased, there is φ 2.5mm to become φ 5mm, then become φ 7.8mm, guarantee that 6 inside pressure of cover is uniform in entire.In described
Air intake duct 3 is provided between cover and outer outlet body, air intake duct 3 is connected to an escape pipe 4, it is provided with negative-pressure air fan in escape pipe 4,
Negative pressure is generated at escape pipe 4 by negative-pressure air fan.Spacing 5mm in gap between outer outlet body 5 and interior cover 6, Lower Lower connection
Place distance 30--50mm is interrupted, it can be ensured that dust will not be spread from this surrounding at runtime using interruption spot welding；Air intake duct 3
It is upper to be evenly distributed with 6 suction holes and more remoter bigger apart from escape pipe 4, while 6 suction hole gross areas are than total air-breathing on interior cover 6
Hole area greatly at least 20% just can fully ensure that pressure reaches requirement in inner cover body 6 in this way；Simultaneously for hygienic requirements, inhaling
Increase dust cover 2 between tracheae 3 and feeder pipe 1, prevents from being here formed as dead angle, dust accumulates, and cleaning is difficult.
Suction hole total sectional area on air intake duct 3 is not more than the sectional area 70% of escape pipe 4.Outer outlet body 5 and interior cover 6 it
Between gap spacing 5mm.
The course of work of above scheme is as follows:
Particulate dust falls through into packaging bag from intermediate feeder pipe 1, and the dust that material falls generation leads to air
The suction hole being distributed on interior cover 6 is crossed, is drawn into the cavity between interior 6 outer outlet body 5 of cover, then passes through the remittance on air intake duct 3
Collection hole is pooled in air intake duct 3, finally introduces air into negative-pressure air fan discharge from escape pipe 4.Wherein interior cover 6 can with when section
Product is trapezoidal taper thin plate, is onboard covered with circular suction hole, and suction hole size is distributed according to pressure, is gradually increased outward from interior
Large aperture；6 suction holes are uniformly distributed on air intake duct 3, the size of suction hole is distributed according to pressure, Zi close to being far gradually increased.
The effect of above scheme is as follows:
Entire interior cover 6 is air suction opening entirely in dust hood, so that interior 6 inner cavity of cover is in uniform negative pressure state, effectively avoids
Other dust hoods only have the air quantity concentration problem of an intermediate air suction opening, and energization effectively absorbs the aerial dust of floating, Du
The fire hazard of Jue Liao manufacturing enterprise makes workshop environment more sanitation and hygiene；It is among outer outlet body 5 and interior cover 6 simultaneously
Gap connection, the very convenient dust removed in air suction opening, avoids dust from accumulating breeding colony problem.
Obviously, various changes and modifications can be made to the invention without departing from essence of the invention by those skilled in the art
Mind and range.In this way, if these modifications and changes of the present invention belongs to the range of the claims in the present invention and its equivalent technologies
Within, then the present invention is also intended to include these modifications and variations.
