Summary of the invention
The purpose of this utility model is, for above-mentioned the deficiencies in the prior art, one is provided to install one layer of outsourcing cooling tube outside gun shot additional, by the circulating cooling water cooling gun shot in outsourcing cooling tube, the temperature making gun shot reduces, to be bonded on the inwall of gun shot after solving powder melted by heating, cause the internal diameter of gun shot to diminish, reduce the amount of dusting and even block the water-cooled steel pipe internal plastic coating spray gun of gun shot problem.
This utility model is to realize above-mentioned purpose by the following technical solutions:
This water-cooled steel pipe internal plastic coating spray gun is made up of gun shot, shower nozzle, powder feeding pipe, powder pump, powder bucket, cyclic water tank, outsourcing cooling tube, water inlet pipe and outlet pipe, the right-hand member of gun shot is provided with shower nozzle, the left end of gun shot connects powder pump by powder feeding pipe, powder pump is arranged in powder bucket, it is characterized in that: described gun shot outer surface is set with outsourcing cooling tube, water inlet pipe and outlet pipe are installed on the left end of outsourcing cooling tube, the other end of water inlet pipe connects the water pump in cyclic water tank, the other end of outlet pipe and cyclic water tank UNICOM；After recirculated cooling water in cyclic water tank is pumped into outsourcing cooling tube by water pump by water inlet pipe, then it is circulated by outlet pipe inflow cyclic water tank.
The water temperature of the described pipe inner cooling water in outsourcing cooling tube is less than 45 DEG C.
The length of described gun shot is more than the length of steel pipe, it is ensured that water inlet pipe does not contacts with steel pipe with outlet pipe.
The described recirculated cooling water in cyclic water tank can add coolant according to the needs of pipe inner cooling water water temperature, and coolant is 1:20 with the weight ratio of recirculated cooling water.
This utility model having the beneficial effects that compared with prior art:
This water-cooled steel pipe internal plastic coating spray gun uses and installs one layer of outsourcing cooling tube outside gun shot additional, by the recirculated cooling water in outsourcing cooling tube, gun shot is cooled down, the temperature making gun shot reduces, it is ensured that gun shot in spraying process, the powder in gun shot is not sprayed-on steel pipe the temperature of up to more than 200 degree melt and be bonded on the inwall of gun shot.Thoroughly solve in prior art gun shot during spraying steel pipe inner wall, powder in gun shot is heated after the temperature reaching certain and is melted on the inwall being bonded at gun shot, the internal diameter causing gun shot diminishes so that the amount of dusting reduces, the problem that time serious, even gun shot is blocked.
