Description
Technical field
The utility model is related to cement grinding equipment more particularly to a kind of cement grinding mill main motor collector ring heat radiation protection to fill
It sets.
Background technology
Cement grinding mill is the key equipment that material is broken and then crushes.Ball mill is widely used in cement, silicic acid
Salt product, the production industries such as New Building Materials, refractory material, chemical fertilizer, black and non-ferrous metal ore and glass ceramics are right
Various ores and other grindability materials carry out dry type or wet type grinding.
Cement grinding mill is cement grinding equipment, and motor provides power for it, and cement mill main motor is coiling electric motor, wherein collecting
Electric ring and carbon brush component are worked in the closing shield that an iron sheet plate surrounds, when motor operation collector ring and carbon brush friction add
Upper high current is by generating a large amount of heat, about 90 degree or so of the temperature of collector ring.Shield mainly plays sealing and protection,
It prevents external sundries from falling into, damages collector ring and carbon brush, but the high temperature in shield directly affects the use longevity of collector ring and carbon brush
Life, temperature is high to cause contact resistance between collector ring and carbon brush to increase again, and the waste for exacerbating electric energy change thermal energy generates.
Utility model content
In view of this, the utility model provides a kind of cement grinding mill main motor collector ring heat radiation protection device, efficiently solve
The problem in the prior art extends the service life of collector ring and carbon brush component, reduces waste of energy.
The utility model uses following technical scheme：
A kind of cement grinding mill main motor collector ring heat radiation protection device, including cement mill, the cement mill include motor,
Speed reducer, driving gear, driven gear and roller, the motor and speed reducer are arranged on bottom plate, the output of the motor
Driving gear, the driving gear and driven gear is arranged on the output shaft of the speed reducer in the input shaft of axis connection speed reducer
Engagement, driven gear are arranged on the excircle of roller；The motor is coiling electric motor, the collector ring and carbon brush group of coiling electric motor
Part is arranged in outer shield, and multiple holes are arranged on the outer shield, and the aperture in the hole is less than 8mm.
The outer shield is cylinder-like structure, including upper plate, lower plate and tubular web plate, and tubular web plate is arranged at upper bottom
Between plate and lower plate；It is provided with radiator window on the lower plate.
The through-hole for installing collector ring and carbon brush component is provided on the upper plate.
The aperture is 7 mm.
The beneficial effects of the utility model are：
Outer shield is arranged in the collector ring of coiling electric motor and the external of carbon brush component in the utility model, and is set on outer shield
Multiple apertures are set for radiating, while multiple radiator windows are set on the lower plate of outer shield, realize comprehensive ventilative, heat dissipation,
The temperature of collector ring is less than 60 degree after transformation, and since the contact resistance that temperature reduces collector ring and carbon brush reduces, calorific value is lower
The consumption of electric energy is decreased, the even running of motor is conducive to.
Sundries is fallen into outer shield the utility model in order to prevent, and the aperture for the aperture being arranged on outer shield is less than 8mm, keeps away
Sundries damage collector ring and carbon brush component are exempted from.
The utility model is simple in structure, easy to use, reduces maintenance cost, extends making for collector ring and carbon brush component
With the service life, motor operation balance reduces energy consumption, is suitable for further genralrlization and uses.
Description of the drawings
Fig. 1 is a kind of structural schematic diagram of cement grinding mill main motor collector ring heat radiation protection device of the utility model；
In figure：1- motors, 2- outer shields, 3- bottom plates, 4- speed reducers, 5- driving gears, 6- rollers, 7- driven gears.
Specific implementation mode
As shown in Figure 1, the utility model provides a kind of cement grinding mill main motor collector ring heat radiation protection device, including cement grinding mill
Machine, cement mill include motor 1, speed reducer 4, driving gear 5, driven gear 7 and roller 6, and motor 1 and speed reducer 4 are respectively provided with
On bottom plate 3, driving gear 5 is arranged on the output shaft of speed reducer 4 for the input shaft of the output axis connection speed reducer 4 of motor 1, main
Moving gear 5 and driven gear 7 engage, and driven gear 7 is arranged on the excircle of roller 6；Motor 1 is coiling electric motor, coiling electricity
The collector ring and carbon brush component of machine are arranged in outer shield 2, and multiple holes are arranged on outer shield 2, and the aperture in hole is less than 8mm.
Outer shield 2 is cylinder-like structure, including upper plate, lower plate and tubular web plate, and tubular web plate is arranged in upper plate
Between lower plate；Radiator window is provided on lower plate.It is provided on upper plate for installing the logical of collector ring and carbon brush component
Hole.
Outer shield 2 is arranged in the collector ring of coiling electric motor and the external of carbon brush component in the utility model, and on outer shield 2
Multiple apertures are set for radiating, while multiple radiator windows are set on the lower plate of outer shield 2, may also set up in upper plate scattered
Hot window or heat emission hole form cross-ventilation between radiator windows multiple in this way and the hole of outer shield 2, accelerate air flowing, realize complete
Orientation is ventilative, radiates, and the temperature of collector ring is less than 60 degree after transformation, since the contact resistance that temperature reduces collector ring and carbon brush subtracts
Small, the lower consumption for decreasing electric energy of calorific value is conducive to the even running of motor.
In order to protect collector ring and carbon brush component, prevent sundries from falling into, the aperture in the hole being arranged on outer shield cannot be excessive,
In order to protect heat dissipation effect, aperture can not be too small, the aperture of the present embodiment be 7mm.The utility model is simple in structure, user
Just, maintenance cost is reduced, the service life of collector ring and carbon brush component is extended, motor operation balance reduces energy consumption, is suitable for
Further genralrlization uses.
The above is only the preferred embodiment of the present invention, is not intended to limit the utility model, all in this practicality
Within novel spirit and principle, any modification, equivalent replacement, improvement and so on should be included in the guarantor of the utility model
