Problems solved by technology

[0002] Since the motor and bearing of the fan cannot operate in a high-temperature environment, plug-in high-temperature centrifugal fans need to be used in high-temperature environments such as hot air circulation, drying equipment, and hot stoves. Although the existing plug-in centrifugal fans can block the insertion The high-temperature contact between the volute and the motor, but because the driving mechanism is close to the heat insulation layer, the heat is transferred through the air, which increases the temperature on the driving side and reduces the life of the fan

Abstract

The invention provides an inserted heat-isolating and cooling mechanism for a high-temperature draught fan. The mechanism comprises a heat dissipating mechanism, a heat isolating mechanism, a heat resisting mechanism and a driving mechanism. The heat dissipating mechanism comprises a heat-dissipating volute arranged in a pipeline, and a heat-dissipating impeller is arranged in the heat-dissipatingvolute; the back end of a main shaft is connected to the driving mechanism; the heat resisting mechanism is arranged on a part, close to a heat-isolating layer, of the main shaft; the heat resistingmechanism comprises a heat-resisting volute, a heat-resisting impeller is arranged in the heat-resisting volute, the heat-resisting impeller is mounted on the main shaft, the air inlet of the heat-resisting volute is formed in one face close to the driving mechanism, the air outlet is formed below the heat-resisting volute; the air inlet of the heat-resisting volute is connected to the air outletof a heat-dissipating coil through a pipeline; the air inlet of the heat-dissipating coil is connected to the air outlet of the heat-resisting volute; the heat-dissipating coil is arranged in a cold water tank. By designing the heat-resisting mechanism, heat transfer can be blocked effectively, and ventilation and heat dissipation are performed by means of water cooling, so that the temperature ofthe driving side is reduced effectively and the service life of the fan is prolonged.

Description

technical field [0001] The invention belongs to the technical field of high-temperature fans, in particular to a plug-in type high-temperature fan heat insulation and cooling mechanism. Background technique [0002] Since the motor and bearing of the fan cannot operate in a high-temperature environment, plug-in high-temperature centrifugal fans need to be used in high-temperature environments such as hot air circulation, drying equipment, and hot stoves. Although the existing plug-in centrifugal fans can block the insertion The high-temperature contact between the volute and the motor, but because the driving mechanism is close to the heat insulation layer, the heat is transferred through the air, which increases the temperature on the driving side and reduces the life of the fan. Contents of the invention [0003] The technical problem solved by the present invention is to provide a plug-in high-temperature fan heat insulation and cooling mechanism designed to block heat ...
