Squeeze-washing cleaning device for heat exchanger

Abstract

The invention discloses a squeeze-washing cleaning device for a heat exchanger. The squeeze-washing cleaning device for the heat exchanger comprises a cleaning water tank, wherein a cleaning pool is arranged on the inside of the cleaning water tank, two sides of the cleaning water tank are provided with pneumatic pumps, the pneumatic pumps are fixed on a motor base, a driving end of one pneumaticpump is fixedly connected with a driving rod, the driving rod extends into the cleaning pool passing through a connecting hole, a water pushing piston is fixed on the inner side of the driving rod, acleaning barrel is arranged on the middle position of the cleaning pool, the cleaning barrel is fixed at a barrel base, the cleaning barrel is composed of a fixed barrel plate and two barrel reverse turning plates, the two barrel reverse turning plates are rotatably fixed on the top walls of two sides of the fixed barrel plate through a side wall rotating shaft, the top of each barrel reverse turning plate is provided with a opening and closing mouth, two limiting blocks are fixed on both sides of the bottom surface of the inner side wall of the fixed barrel plate and the top surfaces of the inner side walls of the barrel reverse turning plates, and two supporting frames are fixed on the inner bottom of a water outlet. The squeeze-washing cleaning device for the heat exchanger improves washing water pressure through the water pushing piston pushing water in the cleaning pool back and forth and improves efficiency and quality of cleaning.

Description

technical field [0001] The invention relates to the field of mechanical cleaning equipment, in particular to a squeeze flushing cleaning device for heat exchangers. Background technique [0002] The shell-and-tube heat exchanger, also known as the shell-and-tube heat exchanger, is a partitioned heat exchanger that uses the wall of the tube bundle enclosed in the shell as the heat transfer surface. The shell-and-tube heat exchanger consists of a shell, a heat transfer tube bundle, Tube sheets, baffles (baffles) and tube boxes and other components are mostly cylindrical shells, with tube bundles installed inside, and both ends of the tube bundles are fixed on the tube sheets. Cleaning requires cleaning of the internal tube bundles of the heat exchanger. [0003] At present, the commonly used cleaning method is to manually use a high-pressure water gun to wash the internal tube bundles one by one, but this kind of work efficiency is low, and there are hundreds of small tube bu...

Problems solved by technology

[0003] At present, the commonly used cleaning method is to manually use a high-pressure water gun to wash the internal tube bundles one by one, but this kind of work efficiency is low, and there are hundreds of small tube bundles inside a large shell-and-tube heat exchanger, and it is very time-consuming to clean. , which also results in high maintenance costs for shell-and-tube heat exchangers. At present, some mechanical devices for cleaning by circulating water flow appear on the market. The cleaning is thorough, so the cleaning efficiency and quality cannot be as good as that of a separate tube bundle high-pressure gun. Therefore, we need a new cleaning device for shell-and-tube heat exchangers that can reduce manual work intensity and realize automatic cleaning functions.
