Abstract

The invention discloses a production process for a purification column used for a water purifier. The production process comprises the following steps: S1, stamping: a step of cutting a filter screen with a stamping mold; S2, injection molding: a step of respectively subjecting an upper end cover (1), a lower end cover (2), a purification column body (3), the filter screen (4) and a filter press ring (5) to injection molding; S3, preparation of a microporous filter (6): a step of cutting a sintered and molded filter with a stamping knife mold; S4, welding of the filter press ring (5); S5, welding of the lower end cover (2) and the purification column body (3); S6, filling of resin or filter material; and S7, welding of the upper end cover (1). Hot plate mold welding is employed in the process of welding, and end face welding and side surface welding manners are adopted. The purification column produced in the invention has high size precision, uniform wall thickness of the column and high cylindricity of the column, can be molded in one shot and does not need subsequent processing; and the production process has the advantages of high injection molding efficiency, low production cost and capacity of perfectly guaranteeing subsequent welding.

Description

technical field [0001] The invention relates to the field of pure water equipment, in particular to a production process of a purification column for a water purifier. Background technique [0002] One type of purification column is a purified water equipment used for pure water production. The purification column mainly includes a purification column cylinder, an upper end cap 1, a lower end cap, exchange resin, a filter screen or a filter sheet. Most of the purification columns currently on the market are formed by extrusion. Extrusion forming is to pass the material through the annular gap composed of the die and the mandrel to form a tube, and then through shaping and cooling to obtain smooth surface, size and geometry. Shape-accurate tubing. The commonly used shaping method is to use outer diameter shaping, that is, the extruded tubular product passes through a shaping sleeve whose inner diameter is the same as the outer diameter of the product, and uses the pressure d...
