Abstract
The invention discloses a positive pressure air-cooled structure of an insertion-type high temperature fan. The positive pressure air-cooled structure comprises an impeller, a water cooling device, a rotating shaft, a heat insulation cylinder, a bearing seat, a motor, a belt pulley, a bearing box, an inflating joint, a water cooling joint, refractory fiber cotton, a sealing ring and the like. The positive pressure air-cooled structure is characterized in that: a belt transmission, the rotating shaft, the bearing seat and a water cooling structure are positioned in the bearing box; the rotating shaft extends out through a shaft hole in the heat insulation cylinder and is connected with the impeller, and the other end of the rotating shaft is connected with the belt pulley; the heat insulation cylinder is arranged outside the bearing box; and the refractory fiber cotton in the lining of the heat insulation cylinder plays a role in heat insulation. The sealing ring is arranged in the shaft hole of the heat insulation cylinder, and the sealing ring is sleeved on the rotating shaft to block heat of a high temperature area; and the inflating joint is arranged on the bearing box, and positive pressure is provided by inflating air into the bearing box, so that the air in the heat insulation cylinder flows out through a clearance between the rotating shaft and the heat insulation cylinder to cool a bearing and the rotating shaft, and the heat of the high temperature area at the impeller is further isolated by air cooling.
Description
Technical field
The present invention relates to a kind of malleation air cooling structure, particularly a kind of malleation air cooling structure of INSERTTYPE high-temperature blower.
Background technique
The INSERTTYPE high-temperature blower is that every profession and trades such as metal smelt, glassware, non-ferrous metal processing are used for heat exchange in the stove pipeline; Improve the uniformity of temperature; Improve the visual plant of heat treated article quality, in running, the impeller of blower fan inserts in the pipeline; High-temperature gas passes to the power transmission part with the rotating shaft attachment portion of air flow conduction and blower fan self with high temperature easily; Thereby influence the normal operation of high-temperature blower, even burn out a bearing, the transmission of heat that therefore how to completely cut off high-temperature blower is the key that guarantees that high-temperature blower runs well.Existing technology mainly is with thermal-protective coating high-temperature blower impeller part and motor, power transmission partly to be isolated; But because the rotating shaft of impeller has connected the power transmission part; Its transmission of heat can transfer heat to the power transmission part; Because of the effect of impeller, the hot blast of HTHP also can enter into the power transmission part from the slit of rotating shaft simultaneously.For addressing the above problem, the present invention provides a kind of malleation air cooling structure of INSERTTYPE high-temperature blower.
Summary of the invention
The objective of the invention is to solve high-temperature blower adopts in the existing technology heat insulation mode and the existing problem of radiating structure, a kind of malleation air cooling structure of INSERTTYPE high-temperature blower is provided.The present invention designs a kind of malleation air cooling structure of INSERTTYPE high-temperature blower, comprises impeller, water-cooling apparatus, rotating shaft, heat insulation tube, bearing support, motor, belt pulley, bearing housing, gas-charging connection, water cooling joint, refractory fiber cotton, seal ring etc., it is characterized in that: belt transmission; Rotating shaft, bearing support and water-cooling apparatus are positioned at bearing housing; Rotating shaft is through the overhanging connection impeller of heat insulation tube internal diameter axis hole, and the other end connects belt pulley, is heat insulation tube in the bearing housing outside; Play heat insulation effect at heat insulation tube liner refractory fiber cotton; In the axis hole of heat insulation tube, seal ring is arranged, seal ring is enclosed within and intercepts the high-temperature zone heat in the rotating shaft, and gas-charging connection is contained on the bearing housing; Employing is inflated in bearing housing malleation is provided; Make the gap outflow of air through between rotating shaft and heat insulation tube in the heat insulation tube,, and further the heat of impeller place high-temperature area is given air cooling and isolate with cooling bearing, rotating shaft.
