Automatic spray gun flushing device for powdery emulsion explosive production

The invention belongs to the technical field of flushing equipment, and discloses an automatic spray gun flushing device for powdery emulsion explosive production, which comprises a base, a supporting rod is fixedly connected to the top surface of the base, a fixing plate is fixedly connected to the top surface of the supporting rod, and a water supply tank fixedly sleeves the top surface of the fixing plate. And the bottom surface of the water supply tank fixedly communicates with a fixed pipe. The insertion pipe and the elastic air bag are arranged in the spray hole of the spray gun in a sleeving mode, air is introduced into the elastic air bag through the air pump, the elastic air bag is inflated and expanded in the spray hole of the spray gun, and therefore the spray hole of the spray gun is sealed, meanwhile, the spray gun is clamped and fixed from the interior through outward expansion force, actual clamping is convenient and fast, operation is easy, and practicability is high. And the position of a con
