Problems solved by technology

[0003] Due to the harsh operating environment of high-temperature fans, especially in environments with relatively high ambient temperature, there is no heat insulation measure for the inner cylinder of the fan. During long-term use, thermal cycles are likely to occur, causing the temperature of the motor to continue to rise, and the motor is easily damaged. There is a fault; at the same time, during the working process of the high-temperature fan, due to long-term work, the drive shaft of the fan is easily damaged, which affects the stable and continuous operation of the high-temperature fan

Abstract

The invention discloses a high-temperature fan with multiple cooling mechanisms, and belongs to the technical field of fan equipment. The high-temperature fan with the multiple cooling mechanisms includes a shell and an inner shell disposed inside the shell. A fan motor is arranged in the inner shell, the fan motor, the inner shell and the shell are all coaxially arranged, a gap is formed betweenthe shell and the inner shell, the right end of the fan motor is connected with a cooling drive shaft, and the cooling drive shaft is provided with a wind turbine blade. A fan is connected to the leftend of the fan motor, and two ventilation holes are formed in the left side wall of the shell. An elastic spiral plate is wound around the axial outer wall of the fan motor to achieve rapid and effective heat dissipation. Cooling water is used for dissipating the fan motor, compressed air is used for radiating a fan drive shaft, the heat dissipation efficiency is effectively improved, the damagephenomenon of the high-temperature fan under high-temperature conditions is effectively avoided; and in addition, vibration can be effectively reduced, and the working stability of the high-temperature fan is improved.

Description

technical field [0001] The invention relates to the technical field of fan equipment, more specifically, to a high-temperature fan with multiple cooling mechanisms. Background technique [0002] High-temperature fans are special fans, specially used in high-temperature workplaces, and their materials have strong resistance to high temperature and high pressure. High-temperature fans mainly include: stainless steel high-temperature resistant fans, transmission high-temperature fans, centrifugal high-temperature fans, etc. High-temperature fans are widely used in chemical industry, petroleum, metallurgy, forging, electric power, nuclear power plants, environmental protection and other fields. The high temperature fan is mainly composed of impeller, casing, air inlet, motor, connector, cooling blade and other parts. [0003] Due to the harsh operating environment of high-temperature fans, especially in environments with relatively high ambient temperature, there is no heat in...
