Description

Automatic medicine adding device of water purifier

Technical Field

The utility model relates to the technical field of water purifier dosing, in particular to an automatic dosing device of a water purifier.

Background

The water purifying equipment is common equipment for sewage treatment, and a proper amount of medicament is generally required to be added into the reaction tank in the process of treating sewage, so that impurities in the sewage are precipitated and clean water is discharged; in the traditional dosing mode, the medicament is added into the reaction tank through the water pump, additional equipment is needed, and the production cost of the equipment is increased.

Disclosure of Invention

In order to overcome the defects of the prior art, the utility model aims to provide an automatic medicine adding device of a water purifier so as to solve the problems.

To achieve the purpose, the utility model adopts the following technical scheme:

the utility model provides an automatic medicine adding device of a water purifier, which comprises a water pipe, a water stop valve fixed on the water pipe, a side bent pipe symmetrically fixed on one side of the water pipe, a venturi tube arranged on the side bent pipe, a medicine sucking pipe fixed on the venturi tube and used for sucking medicine liquid, and a filter fixed at the water inlet end of the water pipe and used for filtering out impurities in water.

Further, a medicine sucking switch for controlling the opening and closing of the medicine sucking pipe is fixed on the medicine sucking pipe.

Furthermore, a three-way pipe which is connected with the side bent pipe flange is fixedly arranged at the two ends of the water pipe.

Further, an auxiliary water feeding pipe for auxiliary water feeding is fixed at one side of the filter; an auxiliary water adding switch is fixed on the auxiliary water adding pipe.

Further, a filter control switch for controlling the filter to work is fixed on one side of the filter.

The beneficial effects of the utility model are as follows:

an automatic dosing device of a water purifier is characterized in that water is usually added into the water purifying equipment directly from a water pipe, when dosing is needed, a water stop valve on the water pipe is closed, water flow enters from a side bent pipe on the side, suction force is generated by a drug suction pipe under the action of a venturi tube, the drug suction pipe is placed into a medicament, and the medicament is mixed in the water and is added into the water purifying equipment to react with water in the equipment; the medicine adding device omits the use of a water pump, thereby saving the production cost of equipment;

in the process of dosing, water flows through the filter to remove impurities in the water, so that the reaction of the medicament and the impurities in the water in the process of dosing is avoided, and the produced precipitate blocks the water pipe.

Detailed Description

The technical scheme of the utility model is further described below by the specific embodiments with reference to the accompanying drawings.

As shown in fig. 1 to 3, the automatic water purifier dosing device provided in this embodiment includes a water pipe 1, a water stop valve 2 fixed on the water pipe 1, a pair of side elbows 3 symmetrically fixed on one side of the water pipe 1, a venturi tube 4 mounted on the side elbows 3, a drug suction tube 5 fixed on the venturi tube 4 for sucking drug liquid, and a filter 6 fixed on the water inlet end of the water pipe 1 for filtering out impurities in water.

Further, a medicine sucking switch 7 for controlling the opening and closing of the medicine sucking pipe 5 is fixed on the medicine sucking pipe 5; when the dosing is finished, the drug sucking switch 7 is closed, so that water is prevented from flowing out of the drug sucking pipe 5.

Furthermore, a three-way pipe 8 which is in flange connection with the side bent pipe 3 is fixedly arranged at the two ends of the water pipe 1.

Further, an auxiliary water supply pipe 9 for auxiliary water supply is fixed at one side of the filter 6; an auxiliary water adding switch 10 is fixed on the auxiliary water adding pipe 9; when the dosing is performed, the auxiliary water adding switch 10 and the water stopping valve 2 are closed, water passes through the venturi tube 4 from the filter 6, and the water is mixed with the medicament after being filtered, so that the problem that the normal operation of the dosing device is affected by precipitation generated by mixing impurities in the water with the medicament during dosing is avoided; when the medicine is not added, the auxiliary water adding switch 10 and the water stopping valve 2 are opened, and the water enters the water purifying equipment directly through the auxiliary water adding pipe 9 and the water conveying pipe 1.

Further, a filter control switch 11 for controlling the operation of the filter 6 is fixed to one side of the filter 6; the filter 6 may be closed when the filter 6 is not in use.

While the utility model has been described with reference to a preferred embodiment, it will be understood by those skilled in the art that various changes may be made and equivalents may be substituted for elements thereof without departing from the spirit and scope of the utility model. The utility model is not to be limited by the specific embodiments disclosed herein, and other embodiments are within the scope of the utility model as defined by the claims of the present application.
