Quartz Sand Filter Manufacturing Process

(1) The water distribution plate is opened and the hole is welded to the water distributor. It can also be connected with a threaded connection to facilitate future replacement. The leg holes are opened.
(2) The lower head is welded with a branch pipe, which is mainly used to support the water distribution plate.
(3) The branch pipe passes through the water distribution plate and is welded. The water distribution plate and the lower head are welded, requiring double welding on both sides.
(4) Roll the plate and weld the main body and the lower wind head.
(5) Weld the upper head.
(6) The tank body is opened: the upper manhole (which can also be shared with the filling hole), the lower manhole (depending on the distance between the lower head and the water distribution plate), the discharge hole, the air outlet, the water inlet and outlet holes.
(7) Install the water supply pipe and the water distribution thread pipe.
(8) Weld the tank body legs and lifting ears.
(9) Mirror polishing.
(10) Weld the external water pipe of the cylinder.
(11) The water inlet pipe, sewage pipe and water outlet pipe are arranged in a crisscross pattern, and 5 valves are used to distribute the water flow.
