However, there is a drawback in that regular maintenance and management of power supply wiring is required. Further, in the case of a cooling tower, the operation is stopped at night, etc., but there is a problem that the chemical solution may be injected into the water receiving tank even during the stop.
このように、従来装置によった場合は、薬液の注入が
甚だ不正確で殺菌効果、スライム防止効果、スケール防
止効果等が充分発揮されないという問題点があった。As described above, in the case of using the conventional device, there is a problem that the injection of the chemical liquid is very inaccurate and the sterilizing effect, slime preventing effect, scale preventing effect, etc. are not sufficiently exerted.
また、前記したように電気配線工事が必要となる等設
備費が嵩むという不具合点があった。Further, as described above, there is a problem that the facility cost is increased due to the need for electric wiring work.

It is sent to the setter 15. The operation time setter 15 counts time by this detection signal, and starts power supply to the small motor 14 when a predetermined time is reached according to a preset program. When the motor 14 is driven, the crankshaft 21 rotates and the rod communicating with the pneumatic feeding means 12
22 repeats the reciprocating motion as shown in FIG. Along with this operation, air is sucked from the intake valve 23, is sent to the air discharge chamber 25 via the air supply valve 24, and the compressed air is supplied from here to the measuring container 7 through the air pipe 13.
すると、計量容器７内の薬液９は薬液注入管11を通っ

定器15が作動してモーター14が運転を停止するものであ
る。Then, the chemical liquid 9 in the measuring container 7 is pressure-fed through the chemical liquid injection pipe 11 and is discharged into the circulating water 3 in the water receiving tank 4. At this time, the valve body 26 in the check valve 10 is pressed against the upper valve seat 27, so that the chemical liquid transfer pipe 8 is closed. Therefore, almost all the predetermined amount of the chemical liquid 9 in the measuring container 7 is poured into the water receiving tank 4, and the operation time setter 15 is activated and the motor 14 is stopped after a predetermined time has elapsed. .
そして、夜間等循環処理器１が運転を停止すると検出
手段18から信号が出力されないので、動作時間設定器15
は作動せず、従って計量容器７内の薬液９は受水槽４内
に供給されることがない。When the nighttime circulation processor 1 stops operating, no signal is output from the detection means 18, so the operating time setting device 15
Does not operate, and therefore the chemical liquid 9 in the measuring container 7 is not supplied into the water receiving tank 4.
このように、本発明装置によれば、循環処理器が稼働
中のときだけ作動して所定量の薬液を定められた時間に
受水槽内に注入することができるので、消費電力をきわ
めて少なくすることができると共に、特別な電気配線工
事を行う必要がなく経済的にも甚だ有利である。As described above, according to the device of the present invention, since the circulation processor operates only when the circulation processor is in operation and a predetermined amount of the chemical liquid can be injected into the water receiving tank at a predetermined time, the power consumption is extremely reduced. In addition to being able to do so, there is no need for special electrical wiring work, which is very economically advantageous.
また、一旦取付けたあとは薬液ボトルの交換の手間だ
