Therefore, if the plate 47 is positioned at an arbitrary position by turning the adjusting nut 45 within the guide groove 46 section, the hydraulic pressure acts so that the bellows 42 is only up to the plate 47 position even if the bellows 42 expand. As it expands, it is possible to adjust the expansion pressure therein.

The expansion limit control configuration of the bellows 42 affects the input amount of the chlorine chemical solution, and selects the input amount of the chlorine chemical liquid in proportion to the inflow of the additional supply of raw water in comparison to the overall capacity of the raw water accommodated in the reservoir 10. It can be adjusted by setting.

In the configuration of the chemical liquid supply pump 40 according to another embodiment of the present invention, as shown in FIGS. 9 and 10, the guide grooves 46 vertically penetrated at both sides thereof are formed to be long, and the bellows 42 may be formed. The upper side of the plate 47 is disposed, the upper side of the ring 50 having a diameter larger than the outer diameter of the spring 43 is disposed so that the locking screw 51 from both sides of the ring 50 is guide groove Protruding outward through the 46, the fixing nut 52 is assembled to the locking screw 51, respectively.

In this embodiment as well, by loosening the fixing nut 52 and placing the ring 50 at an arbitrary position within the guide groove 46 section, and then fixing the ring 50, the hydraulic pressure acts on the bellows 42 Even if it expands, as the bellows 42 expand only to the plate position, the expansion pressure inside the bellows 42 can be adjusted.

Referring to the operation and effects of the chlorine injection device of the reservoir according to the present invention configured as described above are as follows.

First, prior to filling the raw water in the reservoir 10, the worker puts an appropriate amount of chlorine in the powder or undiluted state through the inlet 23 into the mixing tank 20 and then sealed.

Next, by operating a pump (not shown), the raw water is supplied into the reservoir 10 through the water supply pipe 11.

When raw water is supplied to the reservoir 10, the raw water is also supplied to the water supply pipe 11 and the branched inlet pipe 15.

The supplied raw water is supplied to the inlet 31 of the check valve 30, the piston 34 is moved to the discharge port 32 side while overcoming the force of the spring 35 by the hydraulic pressure of the raw water.

Therefore, the opening 39 and the inlet 31, which are closed on the O-ring 38, are opened and at the same time the groove 39 formed in the opening and closing shaft 37 of the piston 34 and the inner wall of the inlet 31 are formed. The raw water is filled in the mixing tank 20 by being discharged to the connector 33 through the cylinder 36 through the flow path formed therebetween.

When raw water is simultaneously supplied into the mixing tank 20 as described above, chlorine pre-injected is properly mixed with the raw water.

Next, air in the mixing tank 20 in the process of mixing the raw water is supplied into the mixing tank 20 is filled into the bellows 42 through the vent pipe 41 of the chemical liquid supply pump 40 The bellows 42 is pushed by the spring 43 and expands while expanding upward while winning the force.

Since the degree of expansion of the bellows 42 is limited by the plate 47 as described above, the bellows 42 will expand until the bellows 42 are in close contact with the plate 47.

When the expansion of the bellows 42 reaches the limit point, the internal pressure of the mixing tank 20 becomes saturated, so that the raw water supply into the mixing tank 20 is stopped, and the raw water supply of the reservoir 10 is filled with water. Are supplied continuously.

Next, when the raw water is filled to the full water level in the reservoir 10, the float valve 14 floating on the surface of the water is operated to stop the operation of the pump (not shown), the supply of raw water is cut off.

Therefore, as the hydraulic pressure applied to the inlet pipe 15 is cut off, the piston of the check valve 30 is moved back to the inlet 31 by the elastic force of the spring 35, so that O- The ring 38 closes the inlet 31, and the O-ring 38 of the opposite opening / closing shaft 37 ′ opens the outlet 32 so that the groove 39 of the opening / closing shaft 37 ′ A discharge flow path is formed between the inner walls of the discharge port 32.

At this time, the compressed air acting inside the mixing tank 20 is started to be discharged through the connector 33, the spring 43 is released as the expansion state applied to the bellows 42 of the chemical liquid supply pump 40 is released. Plate 47 is instantaneously lowered by the elastic force of the force) to compress and pump the bellows 42.

By the pumping action of the bellows 42, the compressed air inside the bellows 42 is discharged into the chlorine chemical solution through the vent pipe 41.

As a result, the pumping operation of the bellows 42 causes the pressure inside the mixing tank 20 to increase momentarily, so that the chlorine chemical is sucked together along the connection pipe 17 in conjunction with the discharge action of the compressed air, and check valve ( It is discharged to the discharge port 32 through the connector 33 of 30) is added to the raw water in the reservoir 10, the chlorine chemical solution is neutralized with the raw water and diluted to complete the appropriate amount of chlorine input.

As described above, the embodiments of the present invention have been described and illustrated, but the present invention is not intended to be limited to the above embodiments, and various modifications may be made without departing from the scope of the present invention. For example, the shape of the check valve can be arbitrarily changed as needed or a known one can be applied, and the position or structure of the chemical liquid supply pump can be selected in an appropriate form.

As described above, the present invention is to increase the pressure in the mixing tank connected to the supply line by the water pressure of the raw water supplied to the inside of the reservoir to expand the inside of the chemical liquid supply pump, the float valve according to the water level of the reservoir Immediately after the pump is stopped by the operation, an air pumping operation by the contracting action of the chemical liquid supply pump enables automatic injection of an appropriate amount of chlorine liquid in proportion to the inflow of raw water.

Therefore, the installation cost of the chlorine input device is low, and the installation, maintenance, and maintenance are easy and economical advantages. The power source for driving the chlorine input device is unnecessary, and thus the economical effect of chlorine input as the non-power can be achieved. Will be.

In addition, in consideration of the amount of raw water used compared to the total capacity of the reservoir, it is possible to adjust and set the air expansion force that is increased inside the chemical liquid supply pump generated by the water pressure when supplying raw water, so that the reservoir installation environment and the reservoir maintenance process Optimal chlorine concentration in proportion to the volume of raw water can be controlled by selectively adjusting the amount of chlorine chemical solution proportional to the amount of raw water inflow.
