Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of heat exchangers, and particularly relates to a gas-water heat exchanger cleaning device. BACKGROUND

[0002] The main reason for cleaning the heat exchange plates of the heat exchanger is to ensure efficient operation of the heat exchanger, prolong the service life of the equipment, and avoid system failure. During the heat exchange process, scale, oil stains, impurities and other substances may accumulate on the surface of the heat exchanger plates, especially when treating poor-quality media. These deposits can cause heat exchange efficiency to decrease, affecting the performance of the heat exchanger. After the heat exchanger plate surface accumulates dirt, the heat conduction performance will decrease, resulting in poor heat exchange effect. If some chemical substances accumulate on the surface of the heat exchanger plate, the metal may be corroded, causing damage to the equipment.

[0003] The existing cleaning method for the heat exchange plates of the heat exchanger is generally that a technician holds a high-pressure water gun to high-pressure flush the disassembled heat exchange plates of the heat exchanger. Although the above flushing method can clean the surface of the heat exchange plates of the heat exchanger, the cleaning effect is not ideal for the dirt in the dead angle position of the heat exchange plates of the heat exchanger.

[0018] The present application provides a gas-water heat exchanger cleaning device, which has the following advantages compared with the prior art:

[0019] 1. In the present application, the motor can drive the second bevel gear to rotate forward, the right angle edge of the second bevel gear tooth and the right angle edge of the first bevel gear tooth are stressed, at this time, the second bevel gear drives the first bevel gear to drive the lead screw to rotate in the vertical direction, at this time, the lead screw drives the lifting push plate to move linearly in the vertical direction, so as to drive the bearing plate installed on the lifting push plate through the floating support assembly to move linearly in the vertical direction, that is, to drive the limiting insertion rod installed on the bearing plate to move linearly in the vertical direction, thereby assisting the technical personnel to insert the heat exchanger heat exchange plate on the limiting insertion rod, and to lower the heat exchanger heat exchange plate inserted on the limiting insertion rod into the cleaning box for soaking.
