Technical Field

[0001] The invention relates to the technical field of plate heat exchanger cleaning, in particular to a plate heat exchanger blockage cleaning device. Background Art

[0002] As an efficient and compact heat exchange equipment, plate heat exchangers are widely used in the heat exchange process in industrial production. However, in actual use, due to the deposition of impurities, condensed solids, hop resins and other substances in the medium, plate heat exchangers often become blocked, seriously affecting their heat exchange efficiency and service life. Therefore, they need to be cleaned and maintained regularly.

[0003] The current cleaning methods are usually: 1. Manual cleaning: Manually disassemble the plates and rinse and clean them one by one, which increases the complexity of plate loading and unloading and the labor intensity of cleaning, or use ultrasonic cleaning; 2. Ultrasonic cleaning: circulate water inside the plate heat exchanger and use ultrasonic cleaning.

The movable pressing plate is separated first, and then the shovel plate 104 pushes the movable pressing plate to the other side of the plate heat exchanger. Then, the two sets of roller brushes 105 are driven by the supporting device to move between the movable pressing plate and the plate, so that the two sets of roller brushes 105 rotate and move up and down to clean them respectively. Then, the two sets of roller brushes 105 move to make way, so that the two sets of shovel plates 104 continue to be inserted between the next set of plates, so that the two sets of shovel plates 104 separate the plates in turn and push them to the other side of the plate heat exchanger in turn. Every time a plate is separated and pushed, the two sets of roller brushes 105 clean the two sides of the two plates respectively, and this reciprocating cycle is repeated, so that multiple plates of the plate heat exchanger are cleaned in turn.

[0024] The main functions achieved by the present invention are: cleaning multiple plates of the plate heat exchanger in sequence, and cooperating with ultrasonic immersion cleaning at the same time, so as to improve the overall cleaning effect of the equipment on the plate heat exchanger, without separating the guide rods of the plate heat exchanger, and effectively reducing the complexity of the overall disassembly of the plates when cleaning the plate heat exchanger, thereby improving the cleaning efficiency of the plate heat exchanger; by adsorbing and fixing the two sides of the plate heat exchanger, the convenience of the equipment for moving and carrying the plate heat exchanger is improved, and the labor intensity of manual labor is reduced.

[0025] The ultrasonic generator 102, rodless cylinder 203, first cylinder 208, first motor 210, second motor 305, third motor 307, second cylinder 404, pump body 503, electromagnet 602, third cylinder 603, fourth motor 701, fifth motor 802, sixth motor 901 and electric heater 1001 of the plate heat exchanger blockage cleaning device of the present invention are purchased on the market, and technicians in the industry only need to install and operate them according to the accompanying instruction manual, without the need for creative labor by technicians in this field.
