An object of the present invention is the difficulty and purification according to the disinfection management of potable water drinking water generated by the chemical side reaction characteristics of drinking water disinfectant chemicals caused by problems such as loss of drug value, mechanical corrosion and breakdown, manager poisoning tale, inconvenient handling, etc. This is to solve the problem of the safe disinfection management of drinking water for drinking water due to the difficulty of maintaining the proper concentration of the chemical, and the management of the chemical injection device according to the poor environmental conditions of the installation site.

The present invention is a problem caused by the disinfection management of drinking water drinking water treatment plant generated by the chemical side reaction characteristics of drinking water disinfectant chemicals due to problems such as loss of drug value, mechanical corrosion and breakdown, manager toxicity toxicity, handling discomfort, There is a problem of safe disinfection management of drinking water for drinking water due to difficulty in maintaining a proper concentration, and management of a chemical input device according to poor environmental conditions at the installation site.

The present invention is packaged and stored chlorkalky solid chlorine chemicals used for disinfection of water supplies in a synthetic resin of corrosion resistance, and automatically dismantled the packaging when used by a control device to put a certain amount into the dilution tank of the lower dilution solution The apparatus relates to a device for sending drinking water to which a disinfectant is applied to a water tank by injecting a liquid chlorine solution from a dilution tank into a pipe of a well by means of a metering tube pump. In addition to the water purification management by injecting the proper concentration of the chemicals by injecting in conjunction with the device as well as to obtain the effect of maximizing the efficiency of the maintenance by installing the device in both the pit of the water intake well and the high water tank. It relates to an automatic drug injection device characterized in that.

Water purification chemicals injector is a vacuum self-contained chlorine injector that attaches chlorine gas directly to chlorine container valve, solid chlorine injector that directly injects Chlorkalky solid chlorine into water tank, and dilutes solid chlorine in water. Or a liquid chlorine injector which injects liquid chlorine, which is a sodium hypochlorite solution, into a pipe by a metering pump. Among them, a vacuum self-contained chlorine injector that injects chlorine gas is a dangerous and expensive equipment cost for chlorine gas. And because it must be operated by the management of a qualified person with a certain qualification, it is used only in a regular water purification plant, and therefore, a solid chlorine input device and a liquid chlorine input device are mainly used.

The conventional solid chlorine injecting device is a time-controlled solid chlorine injecting method in which a solid drug is introduced by a timer when a certain time elapses, which makes it difficult to perform precise chlorine injecting control. In addition, since the chemical input sensor is mounted at the bottom of each loading tube, if the actual solid chlorine has exited the loading tube but a failure occurs while being located in the conveying hole of the rotating plate, the solid chlorine may not be inputted or a failure may occur. There is a disadvantage that it does not perform a precise injection process. In addition, due to chemical side reactions of chemicals, chemicals are lost during chemical storage or chemical reactions with moisture or organic matters cause the chemicals to be lost. There is a problem of being left unattended. In addition, in the conventional water purification chemicals input device, since the solid chlorine seated in the transport hole of the rotating plate rotates when the rotating plate rotates, the solid chlorine may be damaged due to contact with each other for a long time, thus debris from the solid chlorine is rotated. This acts as an obstacle to the rotation, leading to unstable operation such as an operation stop. In addition, since the solid chlorine in the conveying hole and the solid chlorine in all other load pipes receive frictional forces with the rotation of the rotating plate, there is a problem that frequently causes a failure while causing an excessive force on the motor. In addition, the conventional purified water injection device is a water purification drug is located adjacent to the water tank is a problem that the water purification chemicals are not wet or excessively injected into the drug is generated, disinfection when the medicine is not added Not drinking the drinking water, when excessively ingested, there is a problem that causes discomfort or health risks due to the smell of very strong disinfectant when drinking.

On the other hand, the input device using a conventional liquid chemical is configured to constantly inject the liquid chemical of the aqueous solution in which the solid chemical is diluted by the metering pump, the chemical liquid transfer part of the metering pump due to corrosion due to direct contact with the chlorine component There is a problem that causes frequent failures. In addition, the conventional liquid purified water dispenser is a problem that the drug is diluted in water and the drug price of the drug is naturally lost due to the rapid dissociation reaction when stored in the liquid state, so that the drug does not disinfect and sterilize drinking water. have. In addition, the input device using the conventional solid chlorine has the advantage of long-term drug price maintenance if you use the storage means well, but should be installed at the top of the water tank, the village manager climbs on the water tank mounted on the high ground or pylon in the back of the village There is a problem in that it is inconvenient and dangerous to fill the drug or to manage the device. In addition, the input device using the conventional liquid chlorine is convenient in place management by installing in a well near the village, but the liquid is stored by temporarily administering a large amount of solid chlorine to the dilution tank for long-term management by storing a large amount of aqueous solution Chlorination or liquid sodium hypochlorite solution is stored and used. Liquid chlorine dissolves as time goes by and dissolves the solution in a state where there is no disinfecting component due to drug loss. There is this.
