Abstract
The invention discloses an air cooling type cooling system of a heavy-duty - fan. The air cooling type cooling system comprises a fan shell, a spindle and an impeller. A heat dissipation wheel is arranged between the spindle and the impeller, a protection plate is arranged between the impeller and the heat dissipation wheel, a heat insulating layer is arranged on the protection plate, and air inlet pips are arranged at air inlets of the fan shell. The air inlet pipes are communicated with air outlet pipes through air guide pipes. The air outlet pipes are arranged on a bearing box of the heavy-duty fan and a coupler respectively. The air cooling type cooling system is simple in design, and the purchase cost of materials and equipment installation cost are low.
Description
Technical field:
The present invention relates to the cooling of heavy-load type blower fan, particularly a kind of air-cooled cooling system being applicable to heavy-load type blower fan.
Background technique:
Along with moving forward steadily of industrialization of the country process, the application of Fan Product is more and more wider, and the adaptability of product specification and diversity also more and more realistic operating mode; The application area of heavy-load type blower fan is mainly in dedusting and the cleaning system of the engineerings such as cement, iron and steel, metallurgy, and the type of cooling of conventional heavy-load type blower fan is mainly divided into pressure cooling and the circulating water of recycle oil.The pressure cooling system of recycle oil is equipped with Lubricating-oil Station, by the acting of driven by motor pump machine, by thin oil input shaft bearing case, carries out pressure lubrication on the one hand to bearing, on the other hand along with the tape loop of thin oil in bearing chamber walks heat, cooling bearing; But in the rugged environment of the lowest temperature such as Inner Mongol, the Three Eastern Provinces lower than subzero 40 DEG C, general thin oil is easy to reach pour point, affects the cooling effect of bearing.And circulating water is cast with cyclic water channel on bearing chamber outer wall, suppressed by water pump, cooling water is cooled bearing chamber outer wall, indirect cooling bearing, the condensation point of water is 0 DEG C, must carry out isothermal holding, once there is insulation failure in the rugged environment of the lowest temperature such as Inner Mongol, the Three Eastern Provinces lower than subzero 40 DEG C to water pipe, be easy to cause pipeline frozen, cause bearing temperature rise too high.So the pressure cooling of recycle oil and circulating water exist a lot of monitoring failpoints in the environment that temperature is extremely low, be easy to the normal operation affecting heavy-load type blower fan, therefore develop a kind of new type of cooling and just seem very urgent.
Summary of the invention:
The object of the invention is to design a kind of rational in infrastructure, using effect good, the air-cooled cooling system of the heavy-load type blower fan that is not subject to natural environment influence.
Technological scheme of the present invention is, a kind of air-cooled cooling system of heavy-load type blower fan, it comprises Blower Housing, main shaft, impeller, it is characterized in that: between main shaft and impeller, be provided with radiating wheel, between impeller and radiating wheel, be provided with backplate, described backplate is provided with thermal-protective coating, is provided with air intake pipe at the wind inlet of Blower Housing, air intake pipe is communicated with air outlet tube by guide duct, goes out to be in charge of to be separately positioned on the bearing housing of heavy-load type blower fan and the top of coupling.What impeller was connected with main shaft is hollow reel.Thermal-protective coating is adiabatic asbestos slate.Described radiating wheel is that aluminum alloy material is made.Described air intake pipe and air outlet tube are that metal material is made.Described guide duct is that plastic material is made.
The present invention has the advantage of the following aspects than existing cooling system: 1, wind pipe type design of Cooling System is simple, the purchase cost of material and the installation cost of equipment very low, save construction investment greatly; What 2, the operation of wind pipe type cooling system relied on is blower fan self negative pressure, does not need external connection power source, and saving equipment operating cost greatly compared with recycle oil and circulating water cooling system, from long-term investment, is most economical solution; 3, wind pipe type cooling system does not need user to arrange maintenance point, and the workload safeguarded user is a reduction greatly.
Accompanying drawing illustrates:
Fig. 1 is overall structure schematic diagram of the present invention,
Fig. 2 is partial structurtes schematic diagram of the present invention.
Embodiment:
Specific embodiments of the invention are,
Embodiment 1, a kind of air-cooled cooling system of heavy-load type blower fan, it comprises Blower Housing 4, main shaft 10, impeller 8, radiating wheel 6 is provided with between main shaft and impeller, between impeller and radiating wheel, be provided with backplate 7, described backplate is provided with thermal-protective coating, is provided with air intake pipe 1 at the wind inlet of Blower Housing, air intake pipe is communicated with air outlet tube 3 by guide duct 2, goes out to be in charge of to be separately positioned on the bearing housing 9 of heavy-load type blower fan and the top of coupling 5; Air intake pipe described in the present embodiment and air outlet tube are that metal material is made, and the guide duct described in the present embodiment is that plastic material is made.
The present invention is provided with air intake pipe by the wind inlet place at Blower Housing, by the subnormal ambient of blower fan wind inlet, natural air is sucked by near bearing housing and coupling, take away the air outside bearing housing and coupling, formation air flows, and reaches the effect of cooling bearing box outer wall and coupling; Be engaged in outside shaft seal simultaneously and radiating wheel is installed, a small amount of high-temperature gas revealed from shaft seal can be stoped on the one hand directly to rise impact fore bearing; The heat mainly risen along main shaft heat trnasfer is on the other hand able to major part by radiating wheel and distributes; And the thermal radiation produced to prevent housing side wall is on the impact of drive bearing, setting up adiabatic asbestos slate at backplate place, significantly reducing the heat affecting that housing side wall thermal radiation produces motor bearings.Above aggregate measures can effectively be lowered the temperature to heavy-load type blower fan and cool.
