Abstract

The invention relates to a rotary type hot blast drying device and belongs to special structural equipment for carrying out cleaning and hot blast drying on parts of a passage train and a freight train in railroad. The rotary type hot blast drying device consists of a motor, a motor output transmission device, a rotator, transmission gears, a rotary head, a wind pipe and blast nozzles. The motor is connected with the motor output transmission device through an output shaft of the motor; the motor output transmission device is connected with the rotator; the output end of the rotator is fixedly provided with a driving gear; a set of the transmission gears is engaged with the driving gear; and each transmission gear is fixed with an input shaft of a rotary head body which is fixed on a disc base and corresponds to the disc base. The front end of the rotary head body is provided with the rotary head; the inside of the rotary head body is provided with a wind channel; the top end of the rotary head is provided with the wind pipe; and a set of the blast nozzles are arranged on the wind pipe. The rotary type hot blast drying device has a reasonable structure, advanced design, high cost performance, good drying effect, high automation degree and strong environmental protection, and can be widely applied to cleaning and drying various parts of railway vehicles.

Description

technical field [0001] The invention relates to a special structural device for hot air drying after cleaning parts of railway passenger and freight cars, and is especially suitable for drying bearings after cleaning. Background technique [0002] At present, there are various types of cleaning equipment in railway factories, but the traditional method of spray cleaning is mainly used; various parts after spray cleaning must be dried to avoid rusting of parts. The traditional drying treatment method is mainly carried out by drying or fixed-point drying. This traditional drying treatment method can effectively deal with the residual liquid on the surface of the object, but there are problems with parts with inner holes and blind holes. The main problem is that after drying, the residual liquid on the parts exceeds the standard, which cannot meet the requirements of the Ministry of Railways for the cleaning accuracy of vehicle parts. The reason is that the structural design of...
