Backwashing device of plate heat exchanger

The utility model relates to the technical field of plate heat exchangers, in particular to a backwashing device of a plate heat exchanger, which comprises a console and at least two backwashing modules which are arranged near the plate heat exchanger, wherein the plate heat exchanger is fixedly connected with a corresponding medium inlet pipe and a corresponding medium outlet pipe at the position corresponding to the input and output of each medium. The backwashing device of the plate radiator has the beneficial effects that the backwashing device of the plate radiator is high in washing speed, and backwashing operation can be more frequently inserted in the working period of the plate heat exchanger, so that the service life of equipment can be effectively prolonged, washing liquid in the washing process can be repeatedly recycled, resources are saved, and the production cost is reduced. And on the other hand, the cleaned impurities can be collected by the separation filter and then manually cleaned, the cl
