Description
Technical field
The invention belongs to suspension mill technical fields, and in particular to a kind of overhang roll mill with air ducting.
Background technique
Suspension mill is widely used in the industries such as metallurgy, building materials, chemical industry, mine, expressway construction, water conservancy and hydropower, right
Mineral products material carries out powder crushing process processing.Suspension mill is mainly by the components group such as host, analysis machine, powder collector, blower, pipeline
At, release mesh material in feed bin is continually fed into host milling compartment through batcher and is ground, the powder after grinding by from
Heart blower is blown into the indoor air-flow of milling and takes away, and is classified through analysis machine, the powder for meeting fineness enters with air-flow through pipeline
It in whirlwind powder collector, is separated and collected, finished product powder is discharged through discharge valve, and the air-flow after separation is returned by whirlwind powder collector upper end
Air hose sucks centrifugal blower.Underproof powder is thrown toward barrel after analysis machine separates, along barrel fall after come back to mill
Machine grinding.Wherein host is made of base, air inlet spiral case, cylinder, grinding roller component and transmission mechanism etc., passes through the bull ring on base
It squeezes with the grinding roller component of rotation with grinding and completes powder processed.
In suspension mill field, how effectively to increase intake, improves yield, be an important class for a long time
Topic.In order to improve yield, the prior art mostly uses greatly the mode for improving power of fan.With the increase of intake, existing structure
It will cause loss also to increase, and the reflux gas containing powder is also increasingly severe to the abrasion of air inlet spiral case.That is, logical
Often, while increasing power of fan, yield is not improved with power ratio, and the reflux gas containing powder is to air inlet
The abrasion of spiral case is also very serious, reduces the service life of spiral case.
Summary of the invention
The purpose of the present invention is to solve the above-mentioned problems of the prior art, provide a kind of outstanding with air ducting
Roller mill.
To achieve the above object, the present invention adopts the following technical scheme: a kind of overhang roll mill with air ducting, including machine
Seat and air inlet spiral case, several slanting base air duct columns are along the circumferential direction evenly arranged in base, enter the wind spiral case by snail
The volute tongue region of shell top plate, spiral case side plate and spiral case bottom plate composition, the air inlet spiral case is provided with wind deflector, air duct wind-guiding
The front of plate is arc section, and rear portion is planar section, and arc section and planar section are smoothly connected.
The wind deflector of arc section is mounted on the inside of the spiral case side plate in volute tongue region, the wind deflector installation of planar section
On the inner sidewall of the base air duct column in air inlet region, the bottom of wind deflector is mounted on the inside of spiral case bottom plate and base
On the bottom of air duct.
The section of the air inlet spiral case is the side for the horizontal U-shape being made of spiral case top plate, spiral case side plate and spiral case bottom plate
Hatch frame.
The beneficial effects of the present invention are: the present invention overcomes the prior art to increase the technology prejudice of power of fan merely, leads to
It crosses and wind deflector is set in the volute tongue region of air inlet spiral case, this has the overhang roll mill of air ducting, and blower can be made to provide
Most air-flows enter milling compartment, reduce the loss of air-flow, improve the yield of flour mill, reduce the reflux gas containing powder
Abrasion to air inlet spiral case reduces interference of the reflux gas to air inlet air-flow, to increase intake, the structure is simple, has
The advantages that processing and installation processing performance is good, low manufacture cost.
Detailed description of the invention
Fig. 1 is the structural diagram of the present invention.
Fig. 2 be Fig. 1 E-E to cross-sectional view.
Fig. 3 is overall structure diagram of the invention.
Specific embodiment
Present invention will be further explained below with reference to the attached drawings and specific embodiments.
The art of this patent personnel have found in long-term working practice, and in the suspension mill course of work, yield is not
Be as intake linearly increases, main reason is that: it is fully open structure, blower at volute tongue in spiral case that host, which is entered the wind,
Air-flow a part of offer enters milling compartment by the air duct of base, some air-flow by open volute tongue again
Spiral case air inlet inside region is returned to, milling compartment is not entered into, does not play the role of conveying powder.That is, using opening
The volute tongue for putting formula is easy to cause air intake efficiency low, and air flow losses are more.
After having found this phenomenon, this patent overcomes the prior art to increase the technology prejudice of power of fan merely, with drop
Low reflux gas increases intake to the interference of air inlet air-flow, specific as follows:
As shown in Figure 1-3, the present invention provides a kind of overhang roll mill with air ducting, including base 5 and air inlet spiral case, base 5
Several slanting base air duct columns 6 are inside along the circumferential direction evenly arranged with, enter the wind spiral case by spiral case top plate 1, spiral case side plate 2
It is formed with spiral case bottom plate 4, the volute tongue region for entering the wind spiral case is provided with wind deflector 3, and 3 fronts of wind deflector are circular arc
Section, rear portion is planar section, and arc section and planar section are smoothly connected.
The wind deflector of arc section is mounted on 2 inside of spiral case side plate in volute tongue region, the wind deflector peace of planar section
On the inner sidewall of the base air duct column 6 in air inlet region, the bottom of wind deflector 3 is mounted on 4 inside of spiral case bottom plate
On the bottom of base air duct.
The section of air inlet spiral case is the side opening for the horizontal U-shape being made of spiral case top plate, spiral case side plate and spiral case bottom plate
Structure.The section configuration of spiral case is entered the wind in the present invention and application No. is the disclosed air inlets of the patent of invention of " 201610009507.2 "
The section configuration of spiral case is identical.
Overhang roll mill provided by the invention with air ducting, by the way that air duct wind-guiding is arranged in the volute tongue region of air inlet spiral case
The air-flow of plate, the overwhelming majority that blower can be made to provide enters milling compartment, reduces the loss of air-flow, improves the yield of flour mill,
Reduce abrasion of the reflux gas containing powder to air inlet spiral case, interference of the reflux gas to air inlet air-flow is reduced, to increase
Intake, the structure is simple, has many advantages, such as that processing and installation processing performance is good, low manufacture cost.
The above is the preferred embodiment of the present invention, it is noted that for those skilled in the art, this hair
It is bright to be not limited to the embodiments described above, under the premise of not departing from general idea of the present invention, can also make it is several variation and
It improves, these also should be considered as protection scope of the present invention.
