Abstract
The utility model water cooling type hot flow blower, which is in operation in a controlled atmosphere environment and is used for a heat treatment furnace. The utility model comprises an impeller, a motor stator, a motor housing, a middle fan, a reflecting and heat radiating disc, a Small fan, a lower bearing seat, an internal cooling type bearing panel, an outer barrel of a fan, a water inlet pipe, and a water inlet pipe. The motor housing is an interlayer; the water inlet pipe and the water outlet pipe penetrate through the outer barrel of a fan and is communicated with the interlayer of the motor housing; the lower bearing seat and the internal cooling type bearing are provided with water passages. The utility model has a good cooling effect, and operating cost does not need to be additionally increased.
Description
The utility model relates to a kind of Hot-flow fan, relates in particular to a kind of water-cooled Hot-flow fan of using at the heat-treatment furnace of controlled atmosphere environmental work.
Generally be used for Hot-flow fan that the controlled atmosphere environment works and be with the outer bucket of blower fan with blower motor be sealed in stove in the space that communicates, owing to must rotate at a high speed for a long time during machine operation, and the first half of impeller and motor shaft works long hours in the high-temperature region, and itself can heating during machine operation etc. factor, make the heat radiation of motor become to influence the whether key issue of operate as normal of blower fan.
The prior motor type of cooling mainly contains two kinds: 1. utilize the low temperature nitrogen cooling of flowing, advantage is that cooling effect is better, and shortcoming is to need the one cover nitrogen refrigerating circulatory device of configuration in addition, and operating cost is higher.2. the outer bucket with blower fan is designed to interlayer, pass to recirculated cooling water in the interlayer, the advantage of this method is simple in structure, do not need other operating cost, its shortcoming is that outer bucket inwall and motor housing still are separated with one section space, be the gas of self in this space, and that the thermal conductivity of gas is compared with steel is much smaller, so cooling effect is bad.
The purpose of this utility model is to provide a kind of good cooling results at the existing defective of the above-mentioned type of cooling, need not increase the art cold type Hot-flow fan of operating cost again in addition.
Task of the present utility model realizes in the following manner: this water-cooled Hot-flow fan comprises impeller, motor shaft, motor stator and motor housing, motor housing is provided with the outer bucket of blower fan outward, fan and reflection heat dissipation plate during the impeller below is provided with, the motor stator below is provided with small fan and step, the outer bucket of blower fan left surface top is provided with water inlet pipe, the outer bucket of blower fan right flank below is provided with outlet pipe, it is characterized in that: motor housing is an interlayer, be provided with one or more baffle liner in the interlayer, be provided with aquaporin in the step, the motor stator top is provided with the inner-cooled bearing panel, also be provided with aquaporin in the inner-cooled bearing panel, water inlet pipe and outlet pipe pass the outer bucket of blower fan and communicate with the interlayer of motor housing, and outlet pipe communicates with the water channel of inner-cooled bearing panel by the outer water channel of bucket.
In the utility model, middle fan and reflection heat dissipation plate can be combined as a whole.
In the utility model, can outside blower fan, in the bucket liquid level alarm device be set.
The utility model is compared with prior art: because the stator winding of motor and the direct cooling that step can obtain cooling water, cooling-down effect is very obvious; The middle fan of blower fan is combined as a whole with the reflection heat dissipation plate, the width of cloth that helps in the reverberatory furnace is penetrated heat and is distributed the high temperature that the transmission of motor shaft the first half comes, and evenly send in the stove controlled atmosphere, good cooling results, prolonged the service life of motor greatly, the furnace gas forced circulation is flowed, thereby can significantly improve product quality and shorten the production cycle.In addition, the utility model need not increase operating cost, and operation and maintenance are all very convenient.
Fig. 1 is a structural representation of the present utility model.
Below in conjunction with drawings and Examples the utility model is described in more detail.
Embodiment:
Comprise impeller 1 with reference to this water-cooled Hot-flow fan of Fig. 1, motor shaft 13, motor stator 5 and motor housing 6, motor housing 6 is an interlayer, be provided with four baffle liners 12 in the interlayer, the motor housing 6 outer outer buckets 7 of blower fan that are provided with, the outer bucket of blower fan 7 left surfaces top is provided with water inlet pipe 4, the outer bucket of blower fan 7 right flanks below is provided with outlet pipe 10, water inlet pipe 4 and outlet pipe 10 pass the outer bucket of blower fan 7 and communicate with the interlayer of motor housing 6, fan 2 and reflection heat dissipation plate 11 during impeller 1 below is provided with, middle fan 2 is combined as a whole with reflection heat dissipation plate 11, motor stator 5 belows are provided with small fan 8 and step 9, be provided with aquaporin in the step 9, motor stator 5 tops are provided with inner-cooled bearing panel 3, also are provided with aquaporin in the inner-cooled bearing panel 3, and outlet pipe 10 communicates with the water channel of inner-cooled bearing panel 3 by the outer water channel of bucket.
Cooling water passes outside the blower fan interlayer that bucket 7 enters motor housing 6 along water inlet pipe 4, cooling motor stator 5 and step 9 successively, pass bucket 7 outside the blower fan along outlet pipe 10 then, water channel enters inner-cooled bearing panel 3 outside bucket again, cooling upper bearing (metal) position and panel are drawn this cooling water from inner-cooled shaft bearing plate 3 at last and are entered the former furnace part that just needs cooling water.
