心部に水平回流を生起させるためのアジテーターを備え
たものが使用されている。Conventionally, dyeing chemicals, paper strength enhancers and chemicals for fixing them are added to papermaking raw materials, and the raw materials and chemicals are uniformly dispersed and mixed, or various chemicals are uniformly mixed in other liquid materials. Equipped with an agitator for generating a horizontal circulating flow in the center of the tank is used.
このようなケミカルブレンダーは、各薬品の添加順

回流によって攪拌混合され、流出口27から流出する。In such a chemical blender, a plurality of tabs may be used in series as shown in FIGS. 4 and 5, depending on the order and timing of addition of each chemical. That is, each of the tabs 21 has a circular or elliptical horizontal cross section in many cases, and each of the tabs 21 is connected to each other through an over baffle 22. 23 are provided. The driving device 24 of each agitator 23 is supported on a pedestal 25 fixed on the tub 21, and each tub 21 is provided with a step so that the raw material flows down one by one using a head. 26 are connected, and an outlet 27 is opened in the last tab. Further, a chemical injection tube 28 is opened in each tab 21. 29 is a washing shower. Thus, the raw material is supplied from the raw material supply pipe 26 to the first stage tub 21, a predetermined chemical is injected from the chemical injection pipe 28, and the raw material and the chemical are mixed by the horizontal circulation generated by the agitator 23, Second through the over baffle 22 due to the head
The second chemical, which is injected from the chemical injection pipe 28, is stirred and mixed by the horizontal circulation, and further flows down to the final tub 21 through the over baffle 22 by the head. The third chemical injected from 28 is stirred and mixed by the horizontal circulation, and flows out from the outlet 27.

けでは効果なく、作業員が槽内に入って手作業で清掃す
る必要がある等の多くの問題点を有していた。However, in the conventional chemical blender, stirring is performed only by horizontal circulation, so chemicals with poor dispersibility require a lot of time for complete mixing, and when the horizontal circulation is too strong, the liquid level rises and the mixture flows out incompletely. It was easy. Also,
When a plurality of tabs are connected in series, a large installation space is required to connect the tabs via the over baffle 22, as is clear from FIG. Further, chemical slime or the like easily adheres to the inner wall of the tub, and it is not only effective to wash the chemical slime and the like by spraying the washing water from the washing shower 29 but also it is necessary for an operator to enter the tank and clean it manually. And so on.
本考案は、従来のケミカルブレンダーの問題点を解消

いる。In the present invention, in order to achieve the above-described object, a plurality of tabs are connected via an over baffle, and a horizontal flow generating agitator is provided at the center of each tab,
A curved portion facing the inner surface is formed from the upper side to the lower side of each tab, a flow hole is formed in a lower side wall of one curved portion, and an upper portion of the other curved portion is cut off, and these tabs are connected to each other. Opposite connection to form an over baffle,
The horizontal circulation is bent so as to be converted into countercurrent to each other.
なお、アジテーターをタブ上に取外し可能に設けた架
台に支持すると良い。The agitator may be supported on a pedestal that is detachably provided on the tab.

し、エネルギーの節減にも連なる。According to the chemical blender of the present invention, the raw materials sequentially flow into each tub via the over baffle, and the raw materials and the chemicals are stirred and mixed by the horizontal circulating flow generated by the agitator. As shown by the arrows in FIG. 2, the horizontal circulating flow is bifurcated in the tub and converted to countercurrent, which improves the stirring efficiency and also saves energy.

（第１図及び第２図参照）、全体の設置スペースが縮小
される。Further, since the overbaffle of such a chemical blender is constituted by a curved portion protruding toward the inner surface side of each tab, the tabs can be closely connected without any gap (see FIGS. 1 and 2). ), The total installation space is reduced.
さらに、運転中、タブ内壁には薬品スライム等が付着

検、交換等も容易となる。Further, during operation, chemical slime or the like easily adheres to the inner wall of the tub, and since it is difficult to remove the slime only by spraying the washing water, manual cleaning is required, and this cleaning is frequently performed. Therefore, if the agitator is supported on a pedestal that can be detached from the tub, the agitator can be removed from the tub at the same time if the pedestal is removed, and the inside of the tub can be easily cleaned. It will be easier.

薬品注入管８及び洗浄シャワー９も開口されている。Hereinafter, an embodiment of the chemical blender according to the present invention will be described with reference to FIGS. 1 to 3. Tabs 1 each having a circular or elliptical horizontal cross section are connected via an over baffle 2, and each tab 1 is connected. An agitator 3 for generating a horizontal circulating flow is provided at the inner central portion, and a driving device 4 of the agitator 3 is supported on a gantry 5 provided on the tub 1. Also, the raw material supply pipe 6 is connected to the tub 1 at the first stage, and the outlet 7 is provided.
Is connected to the last tab 1. Further, a chemical injection pipe 8 and a cleaning shower 9 are also opened in the tub 1.

る。Further, in the over baffle 2, a curved portion directed to the inner surface is formed so as to protrude from the upper side to the lower side on both sides of each tab 1, a flow hole is formed in a lower side wall of the one curved portion, and the other curved portion is formed. The upper portion is removed, and these tabs 1 are connected to each other so as to form a circular horizontal section as shown in FIG. 2 or a rectangular horizontal section as shown in FIG. The over baffle 2 functions to convert the horizontal circulating flow generated by the agitator 3 into counter currents as shown by arrows in FIG.

ことができる等の極めて有用なる効果を奏する。As described above, according to the present invention, a curved portion facing the inner surface is formed from the upper side to the lower side of each tab, a flow hole is formed in the lower side wall of the one curved portion, and the upper side of the curved portion on the other side is formed. The tabs are cut off, the tabs are connected to each other to form an overbaffle, and the horizontal circulating flow is bent and converted into countercurrent. Therefore, the horizontal circulating flow in the tabs is bent by the opposing overbaffles to face each other. Since the flow is a flow, the stirring efficiency is improved, and the required energy can be saved. In addition, since each tab is tightly closed without any gaps, the installation space can be minimized, and the agitator base can be removed to facilitate cleaning of the tank, inspection of the agitator, and / or replacement. It has an extremely useful effect, for example,
