Detailed Description
The following describes preferred embodiments of the present invention with reference to the accompanying drawings.
As shown in fig. 1 and 2, the cooling structure of the kiln head exhaust fan motor comprises a base 1 and a motor body 2 arranged on the base 1, and further comprises an external air cooling structure.
The external air cooling structure comprises a cooling ventilation hood 3, an air heat exchanger 4, a water separator 5 and a water collector 6. The cooling ventilation hood 3 comprises a U-shaped outer frame and a baffle arranged at one end of the U-shaped outer frame; the U-shaped outer frame is inverted and fixed on the base 1; the baffle is fixed in U type frame one end, and the baffle forms the notch with motor coupling or main shaft and locates. The air heat exchangers 4 are three and fixed on the cooling ventilation hood 3 and are respectively arranged on two sides of the motor body 2 and above the motor body, and water inlets and water outlets of the three air heat exchangers 4 are all led above the cooling ventilation hood 3. The water separator 5 and the water collector 6 are arranged on the upper side of the cooling ventilation hood 3; the water separator 5 is connected with the water inlets of the three air heat exchangers 4, and the water collector 6 is connected with the water outlets of the three air heat exchangers 4; the water inlet of the water separator 5 is connected with the water outlet of the water chilling unit, or connected with a circulating water pool in the cement production system, or connected with other equipment capable of providing low-temperature water in the cement production system, and the water outlet of the water collector 6 is connected back to the water return port of the water chilling unit, or connected with the circulating water pool in the cement production system.
In order to enhance the cooling effect of the motor body 2 by refrigeration, an axial flow fan 7 is arranged on the upper side of the cooling ventilating hood 3, and the axial flow fan 7 corresponds to the air heat exchanger 4 above the motor body 2; meanwhile, a control valve 8 is arranged between the water inlet pipe of the three air heat exchangers 4 and the water separator 5, the control valve 8 can be a manual plug valve or an electric valve, an electromagnetic reversing valve is facilitated, and when the electric valve is adopted, the control of the valve is connected into a control system of the kiln head exhaust fan. The axial flow fan 7 and the air heat exchanger 4 can realize active refrigeration by matching.
The utility model discloses a working process and principle are:
the utility model discloses when using, the cooling method of motor has two kinds. The first cooling mode may be referred to as passive refrigeration; the working process and principle are as follows: the water chilling unit supplies water to the three air heat exchangers 4 through the water separator 5, the water is collected by the water collector 6 and then flows back to the water chilling unit, and the air heat exchangers 4 cool the surrounding air; when the motor body 2 is started, the self-contained cooling fan sucks air around the motor body 2 and then discharges the air through the cooling hood, negative pressure is formed inside the cooling hood 3 based on the layout of the cooling hood 3 when the air around the motor body is sucked, and then the air outside the cooling hood 3 is sucked into the inside through the air heat exchanger 4, air cooling is achieved, and the cooling effect of the motor body 2 is achieved. The second cooling mode is to use an axial flow fan 7 to realize active cooling; the working process and principle are as follows: the water inlet passages of the air heat exchangers 4 at the two sides of the motor body 2 are closed in advance through a control valve 8; cold water only passes the air heat exchanger 4 that is located the upside, opens axial fan 7 back, and axial fan 7 squeezes into cooling draft hood 3 inside with the outside air of cooling draft hood 3, realizes the air cooling when passing through air heat exchanger 4, and low temperature air acts on and realizes the cooling purpose on motor body 2. When the motor body 2 runs at low frequency for a long time, a second cooling mode can be used if cooling needs exist; when the motor body 2 operates at power frequency or high frequency, the first cooling mode can be selected. The first cooling mode may be selected based on the reduced energy consumption requirement.
