を生じるという欠点がある。In the above-described conventional quantitative chemical solution supply device, a small amount of the chemical solution passes through the pump in which the operation is stopped, and flows into the processing tank due to a synergistic effect of the pressure due to the depth of the chemical solution in the chemical solution storage tank and the siphon phenomenon due to the second pipe. Since it is discharged, there is a drawback that the discharge amount varies.

構成されている。In FIG. 1, a fixed-quantity chemical supply device includes a chemical storage tank 1.
And a fixed-rate discharge pump 2 provided at a lower portion of the chemical solution storage tank 1 and connected to the chemical solution storage tank 1 by a first pipe 3. A chemical solution discharged from the pump connected to the fixed-rate discharge pump 2 is supplied to the processing tank. 6 and a second pipe 4 for supplying
A third pipe 5 having one end connected to a portion 4A located above the surface of the chemical solution 7 in the chemical solution storage tank 1 and the other open end connected to the upper surface of the chemical solution storage tank 1 It is composed of

定となる。When the chemical liquid 7 in the chemical liquid storage tank 1 is discharged by the constant-rate discharge pump 2 in a fixed amount by using the present embodiment configured as described above, the discharged chemical liquid is temporarily supplied from the second pipe 4 by the pressure of the pump. Although it rises into the third pipe 5, it falls as the chemical solution flows into the processing tank 6, and disappears from the third pipe 5. Then, the chemical liquid stays near the connection point B of the third pipe 5. For this reason, the pressure on the fixed-rate discharge pump 2 due to the depth of the chemical solution 7 is substantially balanced by the chemical solution 7A in the second pipe 4, and the siphon phenomenon due to the tip of the second pipe 4 also decreases. It is resolved by the inflow of air from the air. Therefore, there is no chemical liquid passing through the fixed-rate discharge pump 2 after the operation is stopped as in the related art, and the discharge amount is constant.

で、正確に一定量の薬液を供給できる効果がある。As described above, according to the present invention, the third pipe having one end opened is provided in a portion of the second pipe for supplying the chemical solution from the constant-rate discharge pump to the processing tank, which is located above the chemical solution surface of the chemical solution storage tank. This can eliminate the influence of the pressure due to the depth of the chemical solution and the siphon phenomenon caused by the second pipe, so that there is an effect that a certain amount of the chemical solution can be accurately supplied.
