Description
Technical field
The present invention relates to a kind of grinding device, specifically a kind of mill with grinding column cooling function.
Background technique
Powdery paints procedure of processing is usually three steps, and the first step carries out all coarse granule shape raw materials and related auxiliaries pre-
Mixing；Second step melts premixing raw material by extruder, makes each component homogeneous in coating in this course, and tabletting at
Type；Third step, molding tablet sanction is broken, it is milled with grinding machine to fragment, the powder after screening grinding is packaged pack, formation
Product.
In milling, grinding machine grinds a second level whirlwind and sorts one blower exhausting of a deduster.In the course of work of grinding machine, out
Material mouth connects air supply duct, and air supply duct is made mill chamber form negative pressure by negative-pressure air fan effect, and negative pressure allows raw material to be flowed by feed inlet,
After raw material enters main mill, main mill high-speed rotation, so that raw material smashes raw material with the grinding column high-speed impact on main mill, and
The screening to powder particle is realized via the grading wheel high-speed rotation of pair mill, is then flowed out by discharge port.Wherein due to grinding column with
Violent friction, therefore temperature with higher when grinding column work can be generated when raw material high-speed impact.When temperature rises to centainly
When degree, it be easy to cause material hot melt to stick together with components such as grinding column, main mills, it is therefore necessary to further change to it
It is kind, to reduce grinding column operating temperature.
Summary of the invention
The purpose of the invention is to overcome prior art there are the shortcomings that, it is simple to provide a kind of structure, easy to use, energy
A kind of mill with grinding column cooling function of flour mill operating temperature is enough effectively reduced.
Object of the present invention is to what is realized with the following methods: a kind of mill with grinding column cooling function, it is characterised in that: its
Including mill ontology and set on the attachment base of its lower end surface, attachment base is connect with spindle motor, and the upper surface of mill ontology is to grind
Disk body central array distribution is provided with several grinding columns, and grinding column position is corresponded on the mill ontology and is also provided with several lead to
Air holes, ventilation hole are arranged through mill ontology upper and lower end face, and the upper outlet port of ventilation hole is directed at corresponding grinding column.
The upper outlet port of the ventilation hole is angularly disposed on mill ontology, and ventilation hole runs through mill ontology upper and lower side
Face, so that air-flow, which passes through ventilation hole from mill ontology lower end, blows to grinding column.
The upper outlet port inclined direction of the ventilation hole is consistent with mill ontology direction of rotation, the lower air inlet of ventilation hole
Port inclined direction is reversed with mill ontology direction of rotation.
The mill ontology upper surface is also equipped with mill end cap, and mill end cap is in a circular table shape, the ventilation hole
Outlet port is arranged on the inclined-plane of mill end cap, and penetrates through with the ventilation hole being set on mill ontology.
The outlet port of the ventilation hole is arranged on the top surface of mill end cap.
The attachment base is integrally formed with mill ontology by metal material.
The beneficial effects of the present invention are: 1, structure is simple, production cost is low, improves the market competitiveness.2, in mill ontology
On offer ventilation hole, air can be blown from lower to upper, reduce mill body temperature, avoid mill temperature is excessively high material is caused to melt
Generate adhesion.3, air-flow guidance constantly can be blowed to mill body surface by several ventilation holes, and mill body surface is avoided to occur
Buildup, so as to avoid in traditional technology because mill ontology top buildup cause with grading wheel friction, existing power loss and
The drawbacks such as mill overheat.4, the outlet port of ventilation hole is contacted using air-flow with grinding column towards grinding column, is reduced grinding column temperature and is blown
It walks to stick in the raw material on grinding column, keeps grinding column cleaning, reduce grinding column operating temperature.

Specific embodiment
Specific further instruction is made to the present invention with reference to the accompanying drawing.A kind of mill with grinding column cooling function,
Be characterized in that: it includes that mill ontology 1 and the attachment base 3 set on its lower end surface, attachment base are connect with spindle motor 4, mill sheet
The upper surface of body 1 is provided with several grinding columns 6 with mill body central array distribution, corresponds to grinding column 6 on the mill ontology 1
Position is also provided with several ventilation holes 5, and ventilation hole 5 is arranged through 1 upper and lower end face of mill ontology, the upper outlet port of ventilation hole 5
It is directed at corresponding grinding column 6.
The upper outlet port of the ventilation hole 5 is angularly disposed on mill ontology 1, and ventilation hole 5 is on mill ontology
Lower end surface, so that air-flow, which passes through ventilation hole from mill ontology lower end, blows to grinding column 6.
The upper outlet port inclined direction of the ventilation hole 5 is consistent with 1 direction of rotation of mill ontology, under ventilation hole 5
Air inlet port inclined direction is reversed with mill ontology direction of rotation.
1 upper surface of mill ontology is also equipped with mill end cap 2, and mill end cap 2 is in a circular table shape, the ventilation hole
Outlet port be arranged on the inclined-plane 21 of mill end cap 2, and be set to mill ontology on ventilation hole penetrate through.
The outlet port of the ventilation hole 5 is arranged on the top surface of mill end cap 2.
The attachment base 3 is integrally formed with mill ontology 1 by metal material.
Working principle: in this case, offering ventilation hole on existing mill ontology, so that flour mill is during the work time,
Constantly there is air-flow to enter from the ventilation hole of mill body bottom portion, is discharged from the ventilation hole of mill ontology upper end.Air-flow is by logical
When air holes, the heat of mill ontology generation can be taken away, so that mill body temperature reduces, avoids mill body temperature is excessively high from causing
Material hot melt generates adhesion with mill ontology.
In addition, when air-flow is discharged from the ventilation hole of mill ontology upper end, since ventilation hole is arranged towards grinding column, gas
Stream can constantly impact grinding column, and first playing reduces grinding column temperature action, second blow away the material sticked on grinding column, keep
The cleaning of grinding column.Simultaneously, air-flow can also impact the surface of mill ontology, and the material for being located at mill body surface is outside
It blows, mill body surface accumulation material is avoided to cause to generate power consumption penalty caused by friction between material and grading wheel.
Therefore compared with traditional technology, the structure in this case advantageously reduces the mill and grinding column temperature of flour mill, so that
Flour mill is capable of the work of stability and high efficiency, reduces operating power consumption, therefore can be widely used to promote.
The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention.The technology of the industry
Personnel are it should be appreciated that the present invention is not limited to the above embodiments, and the above embodiments and description only describe this
The principle of invention, without departing from the spirit and scope of the present invention, various changes and improvements may be made to the invention, these changes
Change and improvement all fall within the protetion scope of the claimed invention.
