Embodiment 1

[0017] One side of the frame of the sliding trolley assembly 2 is provided with two groups of parallel pulleys 5, the lower beam of the frame of the sliding trolley assembly 2 is provided with an overturning shaft 7, and the other side of the frame of the sliding trolley assembly 2 is provided with a water spray pipe of the cleaning device assembly 1; The outer side of the water spray pipe of cleaning device assembly 1 is evenly arranged with high-pressure nozzle group 6; the water spray pipe of cleaning device assembly 1 is installed on the plane corresponding to the turning shaft 7, and the flipping device assembly 3 is set on one side of sliding trolley assembly 2, and the flipping device 3 is turned over. The gear rack 4 of the device assembly 3 is set corresponding to the side frame of the sliding trolley assembly 2, and the gear of the overturning device assembly 3 is set corresponding to the shaft end of the overturning shaft 7; before cleaning, turn on the power, and the...

Embodiment 2

[0019] After turning over, the water supply pump is automatically turned on, and the 17MPa high-pressure water flow enters the cleaning device assembly 1 through the hose, and is forced to wash the heat-exchanging fin tube bundle through the uniformly distributed high-pressure nozzle group 6, and impacts the heat-exchanging fin tube bundle through the high-pressure water flow, Separate the dirt on it.

Abstract

The invention relates to a cleaning and overturning system for an indirect air cooling heat exchange pipe bundle. A pulley is arranged on one side of a sliding trolley assembly, an overturning shaft is arranged on a cross beam on the lower portion of a framework of the sliding trolley assembly, and a cleaning device assembly is arranged on the sliding trolley assembly; a water spraying pipe of the cleaning device assembly and a high-pressure sprayer on the outer side are arranged on the other surface of the sliding trolley assembly; an overturning device assembly is arranged on one side of the sliding trolley assembly, and a rack in the middle corresponds to a gear and is used for overturning the cleaning device assembly. In the cleaning process, a overturning device assembly motor drives the rack to overturn the gear and the cleaning device assembly by 90 degrees, the cleaning device assembly enters a V-type groove of a heat exchange finned pipe set after being overturned, and the heat exchange finned pipe bundle is cleaned. The cleaning water pipe overturning device works in narrow space, the work distance is shortened, the work efficiency is improved, workstation shifting is rapid, and vertical cleaning is facilitated. The sliding trolley is specially designed and installed on the machine frame and can vertically slide to meet the cleaning requirement.

Description

technical field [0001] The invention relates to a cleaning device for an indirect air-cooled heat exchange tube group of power station equipment, in particular to a cleaning and turning system for an indirect air-cooled heat exchange tube bundle. Background technique [0002] The indirect air-cooling device used in the power station is easy to be polluted by dust, weeds, etc. , The density of heat exchange fins is relatively high, and the general cleaning device cannot meet the cleaning requirements of the indirect air-cooling device. In view of the above-mentioned reasons, it is necessary to improve the cleaning device and use method. Contents of the invention [0003] In order to solve the problem that general cleaning devices cannot meet the cleaning requirements of indirect air-cooling devices, and the effect of cleaning dust, weeds and other pollution is poor, the present invention provides an indirect air-cooled heat exchange tube bundle cleaning and turning system t...
