Obviously, the drawings described below are only some embodiments of the present invention. For ordinary technicians in this field, other drawings can be obtained based on these drawings without creative work. Among them:

[0022] Figure 1It is a schematic diagram of the overall structure of the present invention. DETAILED DESCRIPTION

[0023] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0024] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0025] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0026] Example 1, reference Figure 1 , which is the first embodiment of the present invention, and provides a silicon meter dosing method, including a dosing unit 100, including a sulfuric acid water tank 101 and a molybdic acid water tank 102 arranged on the side of the sulfuric acid water tank 101, and a staff member adds the liquid reagent to be tested from the dosing unit 100 into the detection system; and,

[0027] The debugging unit 200 includes a photometer 201 and an automatic thermostat 205 disposed at the bottom of the photometer 201. The photometer 201 performs an impurity analysis on the liquid medicine reagent before it enters the detection instrument to prevent the reagent with too many impurities from entering the detection instrument. The automatic thermostat 205 can heat the liquid medicine reagent to a suitable temperature to facilitate subsequent detection; and

[0028] The medicine outlet section 300 includes a channel selection valve 302 and a sample water channel 303 arranged at the bottom of the channel selection valve 302. The channel selection valve 302 can divert the medicine reagents. Unqualified medicine reagents detected in the front-end debugging section 200 will be discharged as waste water through the channel selection valve 302. Only qualified medicine that can be tested can pass through the channel selection valve 302 and enter the sample water channel 303.

[0029] Specifically, the staff adds the liquid medicine reagent to be tested from the dosing section 100 into the detection system. The liquid medicine reagent of the dosing section 100 enters the debugging section 200 for debugging and then enters the medicine discharging section 300. The medicine discharging section 300 can divert the reagent and discharge the reagent. The reagent that fails the inspection in the debugging section 200 will be directly discharged from the system as waste water. Only qualified reagents can enter the inspection system. In the dosing section 100, the solution hangs the medicine box vertically upside down above the instrument, uses gravity to let the medicine flow downward automatically, and uses a one-way throttle valve to control the flow of the medicine. Finally, the medicine is sent to the measurement system. Ordinary PVC pipes can replace expensive peristaltic pump pipes, reducing the cost of the entire system.

[0030] Example 2, reference Figure 1 , which is the second embodiment of the present invention. Different from the previous embodiment, sulfuric acid reagent is contained in the sulfuric acid water tank 101, molybdic acid reagent is contained in the molybdic acid water tank 102, an oxalic acid water tank 103 is arranged on the side of the molybdic acid water tank 102, oxalic acid reagent is contained in the oxalic acid water tank 103, and reducing agent water tank 104 is arranged on the side of the oxalic acid water tank 103, and reducing agent water tank 104 is contained in the reducing agent water tank 104. The detection system can perform separate dosing detection on the above various reagents, and can also perform mixed dosing detection.

[0031] Furthermore, the bottoms of the sulfuric acid water tank 101, the molybdic acid water tank 102, the oxalic acid water tank 103 and the reducing agent water tank 104 are all provided with a medicine discharge pipe 105, which is a PVC hose with a diameter of 1 mm to 5 mm. The medicine box is vertically hung upside down above the instrument, and gravity is used to let the medicine flow downward automatically. A one-way throttle valve is used to control the flow of the medicine, and finally the medicine is sent to the measurement system. A first foam tester 202 is provided on the top of the photometer 201. The first foam tester 202 and the medicine discharge pipe 105 are connected. 05 is connected, the first foam tester 202 is connected to the photometer 201, a second foam tester 203 is arranged at the bottom of the photometer 201, the second foam tester 203 is connected to the photometer 201, a turbine agitator 204 is arranged at the bottom of the second foam tester 203, the turbine agitator 204 is connected to the second foam tester 203, an automatic thermostat 205 is arranged at the bottom of the turbine agitator 204, and the automatic thermostat 205 is connected to the turbine agitator 204.

[0032] Specifically, the reagents in various water tanks enter the first foam tester 202 through the medicine discharge pipe 105 to prevent a large amount of air from being mixed into the reagents during the dosing process to form foam. The first foam tester 202 will detect the foam therein. If there is too much foam that is not conducive to detection, it will be directly discharged as waste water. After passing the first foam tester 202, the reagent flows into the photometer 201, and the photometer 201 performs impurity detection on it. If there are too many impurities and it is also unqualified, it will be discharged as waste water without further detection. The qualified reagents detected in the photometer 201 will enter the second foam tester 203 for a second foam detection. After the qualified detection, the reagents that need to be mixed will enter the turbine agitator 204, and after being mixed by the turbine agitator 204, they will enter the automatic thermostat 205 to be heated to a suitable temperature and then enter the medicine outlet section 300, and then be discharged to the detection instrument through the medicine outlet section 300 for detection. If mixing is not required, the reagents will directly enter the automatic thermostat 205 to be heated and then enter the medicine outlet section 300, and enter the medicine solution detection instrument for detection.

[0033] Example 3, reference Figure 1 , which is the third embodiment of the present invention. Different from the previous embodiment, the medicine discharging part 300 includes a connecting pipe 301 arranged at the bottom of the automatic thermostat 205, the connecting pipe 301 is connected to the automatic thermostat 205, the bottom of the connecting pipe 301 is connected to the channel selection valve 302, and an anion exchanger 305 is arranged on the bottom side of the channel selection valve 302.

[0034] Furthermore, a wastewater channel 304 is provided at the bottom of the channel selection valve 302 , the wastewater channel 304 is connected to the channel selection valve 302 , the bottom of the wastewater channel 304 is connected to the anion exchanger 305 , and a sample water channel 303 is provided on the side of the wastewater channel 304 , the sample water channel 303 is connected to the channel selection valve 302 .

[0035] Specifically, the reagent enters the connecting pipe 301 after passing through the automatic thermostat 205, and enters the channel selection valve 302 from the connecting pipe 301. The reagent is diverted from the channel selection valve 302. The qualified reagents tested in the debugging unit 200 will enter the sample water channel 303 and be discharged into the detection instrument, while the unqualified reagents will be discharged from the wastewater channel 304 into the anion exchanger 305 for wastewater treatment.
