Abstract
The utility model relates to a high-temperature ventilator, which comprises a motor, a belt transmission, a rotary shaft, a bearing seat, an impeller, an insulating layer. The device is characterized in that the belt transmission, the rotary shaft, the bearing seat are located inside a frame; the rotary shaft extends out by passing through an inner diameter shaft hole of the frame and is connected with the impeller; the outside of the frame is provided with a heat insulating layer; a sealing ring is arranged at outside of a shaft hole of the frame. The sealing ring is tangent with the rotary shaft; an inner circular groove is arranged at inner side of the heat insulating layer; the rotary shaft is provided with a vane; the vane is located inside the circular groove; a small vane is arranged at the side of the impeller towards the heat insulating layer. The air discharging direction of the vane is back towards the impeller. The utility model has the advantages that the device can insulate heat of a high temperature area of the impeller in order to prevent an unfavorable effect of high temperature to the normal operations of the motor and the power transmission part.
Description
Technical field
The utility model relates to a kind of blower fan, particularly a kind of novel high-temperature blower.
Background technique
Need to use high-temperature blower in the industries such as the metallurgy in industrial production, casting, food processing at present and carry out supply and exhaust, because when carrying out the high temperature supply and exhaust, the gas of high temperature passes to the power transmission part with the rotating shaft attachment portion of air flows and blower fan self with high temperature easily, thereby influence the normal operation of high-temperature blower, the heat transmission that therefore how to completely cut off high-temperature blower is the key that guarantees that high-temperature blower runs well.Existing technology is isolated casing, impeller part and motor, the power section of high-temperature blower with thermal-protective coating, but because the rotating shaft of impeller has connected the power transmission part, its hot transmission can transfer heat to the power transmission part, because of the effect of impeller, the hot blast of High Temperature High Pressure also can enter into the power transmission part from the slit of transmission rotating shaft simultaneously.
Summary of the invention
The purpose of this utility model is to solve existing the problems referred to above of heat-insulating structure that high-temperature blower adopts in the prior art.A kind of novel high-temperature blower is provided.The utility model designs a kind of novel high-temperature blower, comprise motor, belt transmission, rotating shaft, bearing support, impeller, thermal-protective coating, it is characterized in that: belt transmission, rotating shaft, bearing seat are in a framework, rotating shaft by in the framework through the overhanging connection impeller of axis hole, in the framework outside is thermal-protective coating, there is seal ring in the axis hole outside at framework, seal ring and rotating shaft are tangent, heavy circular groove on the thermal-protective coating inboard, having, one fan blade is arranged in rotating shaft, fan blade is positioned at heavy circular groove, to the thermal-protective coating side small leaf is arranged in impeller face.The air draft direction of fan blade is impeller dorsad.The utility model has the advantages that and the heat of impeller place high-temperature area can be isolated, prevent that high temperature from producing adverse influence to the normal operation of motor and power transmission part.
Description of drawings
Below in conjunction with embodiment the utility model is elaborated.
Accompanying drawing is a structural representation of the present utility model.
Embodiment
Comprise motor 1, belt transmission 2, rotating shaft 3, bearing support 4, impeller 5, thermal-protective coating 6, it is characterized in that: belt transmission, rotating shaft, bearing seat are in a framework, main shaft by in the framework through the overhanging connection impeller of axis hole, in the framework outside is thermal-protective coating, there is seal ring in the axis hole outside at framework, seal ring and rotating shaft are tangent, heavy circular groove on the thermal-protective coating inboard, having, one fan blade is arranged in rotating shaft, fan blade is positioned at heavy circular groove, to the thermal-protective coating side small leaf is arranged in impeller face, the air draft direction of fan blade is impeller dorsad.
Motor is positioned at a side and the high-temperature area isolation of thermal-protective coating during as installed, behind motor rotation, impeller is discharged high temperature air pressurization back by air outlet flue, wherein a fraction of high-temperature gas is under the effect of pressure, flow to the framework direction of placing power section along rotating shaft, but owing to the thermal-protective coating side small leaf is arranged in impeller face, therefore small leaf has formed a negative pressure region between impeller and thermal-protective coating, and the fan blade in the interior heavy circular groove on the thermal-protective coating inboard rotates the barotropic field that the back forms with rotating shaft, therefore between thermal-protective coating and impeller, formed an air stream from the inside to the outside, this air stream has completely cut off the influence of the High Temperature Gas at impeller place to framework inside at the air curtain that the front of fan blade forms, increased the air smoothness in the framework, guaranteed the ambient temperature of the proper functioning of power unit, also will be distributed through the heat that the main shaft transmission enters the framework inboard by impeller simultaneously, seal ring has also stopped high-temperature gas flowing to the thermal-protective coating direction.
Claims (2)
1. novel high-temperature blower, comprise motor, belt transmission, rotating shaft, bearing support, impeller, thermal-protective coating, it is characterized in that: belt transmission, rotating shaft, bearing seat in a framework, rotating shaft by in the framework through the overhanging connection impeller of axis hole, be thermal-protective coating in the framework outside, there is seal ring in the axis hole outside at framework, seal ring and rotating shaft are tangent, and heavy circular groove has a fan blade in having on the thermal-protective coating inboard in rotating shaft, fan blade is positioned at heavy circular groove, to the thermal-protective coating side small leaf is arranged in impeller face.
2. by the described a kind of novel high-temperature blower of claim 1, it is characterized in that: the air draft direction of fan blade is impeller dorsad.
