Automatic dust removing device for heat radiating air hole of large synchronous motor

Abstract

The invention discloses an automatic dust removing device for a heat radiating air hole of a large synchronous motor, and relates to the field of coal chemical synthesis ammonia production devices. The device is characterized by comprising a bowl-shaped wire brush, a spring, a bolt and a fixing plate, wherein the bottom of the bowl-shaped wire brush is connected with the spring, the other end of the spring is fixed on one surface of a fixing plate, the bolt is installed on the other side of the fixing plate, the bowl-shaped wire brush, the spring and the bolt are coaxial, and form an assembly,and 8-10 assemblies are installed on the fixing plate in a slotted shape. Technical personnel in the field are devoted to developing the automatic dust removing device for the heat radiating air holeof the large synchronous motor, on the condition that a rotor is not pulled out, catkin, dust, grease dirt and the like accumulated on the air hole can be thoroughly removed, so that the heat dissipating air hole in the operation of the motor can be kept unblocked, ventilating and heat dissipating of the motor can be ensured, the temperature rise of the motor can be reduced, the electric energy loss of the motor is reduced, faults or halt conditions of the motor are avoided, and the difficulty of dust removal work is simplified.

Description

technical field [0001] The invention relates to the field of synthetic ammonia production devices in the coal chemical industry, in particular to an automatic ash cleaning device for heat dissipation vents of a large synchronous motor. Background technique [0002] When a large synchronous motor is running, due to copper loss and iron loss, a large amount of unnecessary heat energy is generated inside the motor. Under normal circumstances, the temperature rise of the motor is within a reasonable range when it is discharged through the air holes in the stator core. within range. In the synthetic ammonia production system using coal as raw material, there is a lot of oil and dust. When summer comes every year and the temperature gradually rises, especially when catkins and poplars are flooded in April-May, they are flying all over the sky, and they are easy to gather in the motor and are not easy to disperse. , for a long time, the heat dissipation air hole of the motor stato...

Problems solved by technology

[0004] In view of the above-mentioned defects of the prior art, the technical problem to be solved by the present invention is that the large-scale synchronous motor heat dissipation air holes are blocked by dust, causing the motor to overheat and cause failure or shutdown, while the manual cleaning effect is poor, the cleaning work is difficult, and the efficiency is low
