Title:
CHEMICAL SUPPLY DEVICE
Document Type and Number:
Japanese Patent JP2015213891
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a chemical supply device in which a residual amount of a chemical to be supplied can be detected, the constitution of which can be made simpler and which can be miniaturized.SOLUTION: A chemical supply device 20 includes: a housing part 21 having an inflow port 21a through which the water to be treated can be made to flow in and an outflow port 21b through which the treated water can be made to flow out; a rotary shaft 22 arranged in the housing part 21; a chemical holding part 23 which is arranged in the housing part 21 so that it can be rotated around the rotary shaft 22 and in which a chemical 24 is held; a rotation detection part 25 for detecting whether or not the chemical holding part 23 is rotated; and a presentation part 26 for presenting a detected result of the rotation detection part 25. The chemical supply device 20 is constituted so that the chemical holding part 23 is rotated around the rotary shaft 22 when the water to be treated flowing in from the inflow port 21a is contacted with the chemical 24, and the revolution speed of the chemical holding part 23 is changed according to the existing amount of the chemical 24.
