Water treatment chapter's solid powder medicines moment dissolver

摘要

An instant dissolver for solid chemical powder which can improve agitation effect of chemicals and can prevent an impact from being applied to an impeller shaft by removing a vortex phenomenon and smoothly circulating chemicals into a flow path when chemicals injected into a draft tube are instantly agitated and spread to a lower side is provided. An instant dissolver for solid chemical powder in a water treatment plant comprises: an impeller(40) which is formed within a draft tube(20) installed in a dissolution tank(10) and driven by a drive(30) to agitate chemicals injected into the draft tube through an injection pipe(50); a flow path guider(60) installed on the bottom of the dissolution tank underneath the impeller and formed to guide the dissolving water in such a manner that dissolving water agitated is not collided with the bottom of the dissolution tank, but the dissolving water is dispersed into the periphery of a lower part within the dissolution tank and spread upward. The instant dissolver for solid chemical powder further comprises: a guiding cap(22) formed on a lower end of the draft tube to easily spread outward the dissolving water agitated; and a baffle(23) with a proper diameter formed on an inner portion of the draft tube to easily perform instant dissolution of the solid chemical powder.
