Embodiment
Below in conjunction with accompanying drawing of the present invention, clear, complete description is carried out to the technical scheme of the embodiment of the present invention.
As shown in Figure 1, a kind of combined type chemical-adding device that the embodiment of the present invention discloses, comprise grug feeding jar base 1, grug feeding jar 2 and blow-off line 3, grug feeding jar base 1 is for carrying grug feeding jar 2, a grug feeding jar base 1 can carry at least two grug feeding jars 2, namely multiple grug feeding jar 2 is combined into an entirety and is placed on a base, a kind of water treatment agent can be respectively placed in each grug feeding jar 2, also can adjust as required, like this, the conveying that a chemicals dosing plant realizes various medicaments can just be realized.The present embodiment places 4 grug feeding jars 2 on grug feeding jar base 1, the in-built a kind of water treatment agent of each grug feeding jar 2.
Shown in composition graphs 3a and Fig. 3 b, grug feeding jar base 1 comprises the support 12 bottom cofferdam cell body 11 and cofferdam cell body, cofferdam cell body 11 is combined by web member 13 by multiple framework, cofferdam cell body 11 carries grug feeding jar 2, and support 12 is for being fixed support to cofferdam cell body 11.
