Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of chemical detection, and particularly relates to a chemical test probe electrolyte, a preparation method and an automatic electrolyte supplementing device. BACKGROUND

[0002] In the detection and analysis process of the chemical composition of some liquid, various chemical analysis equipment needs to be used. Some chemical analysis equipment uses a detection probe to extend into the liquid to be detected to detect and analyze the composition of the liquid. In order to avoid that the probe is exposed to the air for a long time, so that other substances are attached to the surface of the probe, and the detection accuracy is affected, the probe is usually placed in potassium chloride electrolyte to protect the probe when the probe is not used. However, after the probe is placed in the potassium chloride electrolyte, white crystals are precipitated from the potassium chloride electrolyte and attached to the probe, which affects the detection accuracy of the probe on the liquid to be detected and accelerates the degree of wear of the probe. Therefore, an electrolyte that can protect the probe and is not prone to crystallization needs to be proposed. The chemical test probe needs to be taken out from the electrolyte constantly during use, and therefore the electrolyte in the mechanism for containing the probe needs to be supplemented and replaced. If the electrolyte is not supplemented and replaced in time, the use of the probe will be affected, and the probe cannot be sufficiently protected. Therefore, an automatic electrolyte supplementing device needs to be proposed. SUMMARY

[0003] In view of the above, it is necessary to propose a chemical test probe electrolyte that can protect the probe and is not prone to crystallization.

[0004] In addition, the application also provides a preparation method of the chemical test probe electrolyte.

[0016] In some possible implementations, a remote monitoring system is further included, which is electrically connected with the controller and the monitoring assembly and is used for receiving data of the controller and the monitoring assembly.

[0017] The automatic electrolyte supplementing device provided in the present application contains the electrolyte and the chemical test probe through the containing member, discharges the electrolyte in the containing member through the emptying valve, transmits the electrolyte in the liquid storage barrel to the containing member through the liquid supply pump, controls the emptying valve and the liquid supply pump to work through the controller to discharge the electrolyte in the containing member or add the electrolyte to the containing member, and detects the amount of the electrolyte in the containing member in real time through the detection assembly.

[0036] The commonly used chemical detection probe protection electrolyte is a potassium chloride solution, which has the advantages of good protection effect and convenient preparation. In order to play a protective role, a saturated potassium chloride solution with a concentration of 3 mol / L is usually used. However, when the chemical detection probe is placed in the potassium chloride solution, potassium chloride is easy to precipitate, and white crystals are formed on the chemical detection probe. If not handled in time, the chemical detection probe may even be wrapped. If white crystals are formed on the chemical detection probe, the accuracy of the detection result will be affected, and even the chemical detection probe will be damaged.

[0037] The present application provides a chemical test probe electrolyte, which comprises, by weight percentage: 0.3% to 0.6% of inorganic salt, 25% to 30% of magnesium sulfate, 0.1% to 0.6% of boric acid, 2% to 5% of preservative, and the rest is water.

[0038] In some embodiments, the content of magnesium sulfate is 26% to 28%. In some embodiments, the content of magnesium sulfate is 26% to 28%.

[0039] In some embodiments, the content of boric acid is 0.1% to 0.3%.

[0040] In some embodiments, the content of preservative is 3% to 4%.

[0041] In some embodiments, the inorganic salt is sodium chloride.

[0042] In some embodiments, the preservative is selected from cyclododecyl alcohol, benzoic acid, sodium benzoate, potassium sorbate or calcium propionate.

[0043] In some embodiments, the preservative is cyclododecyl alcohol.

[0044] The chemical test probe of the present application, such as pH meter test probe, is placed in the electrolyte for protection when not in use. The chemical test probe electrolyte provided by the present application contains 0.3% to 0.6% of inorganic salt, which can maintain the ionic balance of the solution. The chemical test probe placed in the chemical test probe electrolyte provides protection, avoiding the shortening of the service life caused by long-term dry storage or immersion in distilled water. The chemical test probe electrolyte also contains 25% to 30% of magnesium sulfate, which can effectively inhibit the crystallization of inorganic salt and avoid the attachment of crystals on the probe to affect the accuracy of detection. The 0.1% to 0.6% boric acid in the chemical test probe electrolyte can play a lubricating and sterilizing role, which can effectively prevent bacteria from growing in the chemical test probe electrolyte and improve the service life of the electrolyte. The 2% to 5% preservative in the chemical test probe electrolyte can play a preservative role, further improving the service life of the chemical test probe electrolyte.

[0045] Referring to Figure 1 The present application also provides a preparation method of the chemical test probe electrolyte, which comprises the following steps:

[0046] S1: Dissolve the inorganic salt and boric acid in water and stir to dissolve;

[0047] S2: Dissolve magnesium sulfate in water and slowly boil for 10 minutes, then filter after cooling;

[0048] S3: Mix the solution prepared in step S1 and the solution prepared in step S2 together, then add the preservative and stir uniformly.

[0049] The preparation method of the chemical test probe electrolyte is simple, easy to operate and easy to use in industrial production, and is a chemical test probe electrolyte with high commercial value.

[0050] Referring to Figure 2The application also provides an automatic electrolyte supplementing device 100, comprising a containing assembly 10, a liquid storage barrel 20, a liquid supply pump 30, a controller (not shown in the figure) and a monitoring assembly 40.

[0051] Specifically, please continue to refer to Figure 2 The containing assembly 10 comprises a containing member 11 for containing the chemical test probe 200 and the electrolyte, and a discharge valve 12 installed on the containing member 11 for discharging the electrolyte in the containing assembly 10; the liquid storage barrel 20 is used for storing the electrolyte; the liquid supply pump 30 is in communication with the containing member 11 and the liquid storage barrel 20 respectively, and is used for transmitting the electrolyte in the liquid storage barrel 20 to the containing member 11; the controller is electrically connected with the liquid supply pump 30 and the discharge valve 12, and is used for controlling the liquid supply pump 30 to supply liquid to the containing member 11 at intervals and controlling the opening and closing of the discharge valve 12; the monitoring assembly 40 is arranged in the liquid storage barrel 20 and is used for monitoring the amount of electrolyte in the liquid storage barrel 20.

[0052] The containing member 11 is, for example, a liquid-containing bottle with an opening, which can be cylindrical, leaky, etc. The containing member 11 is used for containing the electrolyte, which is, for example, the electrolyte of the chemical test probe 200 described above. The containing member 11 is also used for containing the chemical test probe 200. It can be understood that when the probe 200 is not used for detection, the probe 200 is placed in the containing member 11 through the opening at the upper part of the containing member 11, so that the probe 200 is soaked in the electrolyte in the containing member 11. The lower end of the containing member 11 is provided with the discharge valve 12, which is, for example, a peristaltic pump or the like, which can extract the electrolyte in the containing member 11 and then discharge the electrolyte in the containing member 11, so as to replace the new electrolyte.

[0053] The liquid storage barrel 20 is used for storing the unused electrolyte. During use, a large amount of electrolyte can be configured and injected into the liquid storage barrel 20 for use. In this way, the liquid storage barrel 20 not only provides the containing member 11 with electrolyte, but also stores the electrolyte, so as to reduce the frequency of configuring the electrolyte and improve the work efficiency.

[0054] The liquid supply pump 30 is connected with the containing member 11 and the liquid storage barrel 20 respectively, and is used for injecting the electrolyte in the liquid storage barrel 20 into the containing member 11 after the electrolyte in the containing member 11 is discharged, so as to cooperate with the discharge valve 12 to continuously update the electrolyte in the containing member 11.

[0055] The controller is electrically connected with the liquid supply pump 30 and the discharge valve 12, and is used for controlling the discharge valve 12 to be opened to discharge the used electrolyte in the containing member 11, then controlling the discharge valve 12 to be closed, and controlling the liquid supply pump 30 to inject the new electrolyte into the containing member 11.

[0056] The monitoring assembly 40 is arranged in the liquid storage tank 20 and is configured to monitor the amount of electrolyte in the liquid storage tank 20. The monitoring assembly 40 can be a water level detector or the like. It is to be understood that the monitoring assembly 40 can also be provided with an alarm device such as a warning light, a siren or the like. The monitoring assembly 40 can monitor the upper and lower liquid levels in the liquid storage tank 20. When the electrolyte added to the liquid storage tank 20 reaches the upper liquid level, the monitoring assembly 40 can send a reminder such as a flashing light or a siren. When the electrolyte in the liquid storage tank 20 is used to the lower liquid level, the monitoring assembly 40 also sends a reminder such as a flashing light or a siren.

[0057] In some embodiments, the automatic electrolyte replenishing device 100 further comprises a remote monitoring system (not shown in the drawings) electrically connected to the controller and the monitoring assembly 40 for receiving data from the controller and the monitoring assembly 40. In this way, the use of electrolyte can be monitored in real time by the remote monitoring system.

[0058] The working process of the automatic electrolyte replenishing device provided by some embodiments is as follows. First, electrolyte is added to the liquid storage tank 20, and the maximum amount of electrolyte in the liquid storage tank 20 reaches the upper liquid level monitored by the monitoring assembly 40. Then, the controller controls the liquid supply pump 30 to inject electrolyte from the liquid storage tank 20 into the container 11. It is to be understood that when the controller controls the liquid supply pump 30 to inject electrolyte into the container 11, the amount of electrolyte injected at one time can be set according to the volume of the container 11, so that the amount of electrolyte injected at one time by the liquid supply pump 30 into the container 11 will not overflow after the probe 200 is placed in the container 11, and the probe 200 can be immersed in the electrolyte. When the probe 200 is removed from the container 11 for detection, the controller controls the emptying valve 12 to open, and the remaining electrolyte in the container 11 is discharged. Then, the controller controls the emptying valve 12 to close. After the remaining electrolyte in the container 11 is discharged, the controller controls the liquid supply pump 30 to work, and electrolyte is injected from the liquid storage tank 20 into the container 11. In this way, automatic electrolyte replenishing can be achieved. When the electrolyte in the liquid storage tank 20 is used to the minimum liquid level, the monitoring assembly 40 sends a signal to remind that electrolyte should be added to the liquid storage tank 20.

[0059] The controller and the monitoring assembly 40 are electrically connected to the remote monitoring system, which can be arranged in a device such as a computer. The controller and the monitoring assembly 40 upload real-time data to the remote monitoring system, and the working status and historical records of the controller and the monitoring assembly 40 can be viewed by the operator through the remote monitoring system, so that the operator can timely understand the working status of the automatic electrolyte replenishing device 100.

[0060] The automatic electrolyte supplementing device 100 provided by the embodiment of the present application contains electrolyte and a chemical test probe 200 through a containing member 11, can discharge the electrolyte in the containing member 11 through a discharge valve 12, can transmit the electrolyte in a liquid storage barrel 20 to the containing member 11 through a liquid supply pump 30, and can control the discharge valve 12 and the liquid supply pump 30 to work through a controller to discharge the electrolyte in the containing member 11 or add electrolyte to the containing member 11. The amount of electrolyte in the containing member 11 can be monitored and the electrolyte in the containing member 11 can be automatically supplemented or replaced in real time through a detection assembly.

[0132]

[0133]

[0134] Table 2. Protection effect of solution in Comparative Examples 1-16 on probe

[0135]

[0136]

[0137] From the experimental results in Table 1, it can be seen that the electrolyte prepared by using 7.5g-15g of sodium chloride, 2.5g-7.5g of boric acid, 700g-800g of magnesium sulfate, and 50mL-100mL of cyclododecylpropanol, and 1500mL of distilled water, is not easy to crystallize, has a long storage time, and has an effective period of 90 days, and the probe has no corrosion phenomenon. When converted to weight percentage, the electrolyte is composed of 0.3%-0.6% of inorganic salt, 25%-30% of magnesium sulfate, 0.1%-0.6% of boric acid, 2%-5% of preservative, and distilled water, which is not easy to crystallize and can effectively protect the probe, and has a long storage time.

[0138] Meanwhile, according to the experimental results in Table 2, Comparative Example 1-3 is a potassium chloride solution, when only using a potassium chloride solution, it is easy to produce crystallization, and the probe has a slight oxidation phenomenon. Comparative Example 2 and Comparative Example 3 are experiments after reducing the concentration of potassium chloride, and the results still have crystallization phenomenon and probe oxidation phenomenon, and the only difference from Comparative Example 1 is that the crystallization time is prolonged. Therefore, from Comparative Examples 1-3, it can be seen that only reducing the concentration of potassium chloride cannot achieve the purpose of no crystallization of the electrolyte.

[0139] Comparative Examples 4-7 are experiments of adding inhibitors to the potassium chloride solution, in which the inhibitors are citric acid, antioxidants, sodium benzoate, and hydrofluoric acid. When citric acid is added to the potassium chloride solution, the electrolyte has no crystallization, but the probe still has an oxidation phenomenon, which cannot effectively protect the probe. When an antioxidant such as calcium carbonate, disodium ethylenediaminetetraacetate, etc. is added to the potassium chloride solution, the electrolyte is easy to crystallize and has flocculent matter, which cannot meet the requirements. When sodium benzoate is added to the potassium chloride solution, sodium benzoate will undergo a chemical reaction to precipitate sodium carbonate solid, which cannot meet the requirements of the present application. When hydrofluoric acid is added to the potassium chloride solution, since hydrofluoric acid is a strong acid, it will corrode the probe, resulting in serious corrosion of the probe. Therefore, from Comparative Examples 4-7, it can be seen that only adding inhibitors to the potassium chloride solution cannot obtain an electrolyte that has no crystallization and can protect the probe.

[0140] Comparative Examples 8-16 are verification tests for the electrolyte components. Comparative Example 8 uses hydrogen peroxide as the electrolyte, although no crystals are formed, it has strong corrosive properties, has safety hazards, and the probe is severely damaged. Comparative Example 9 uses distilled water to test the probe, distilled water does not contain electrolyte ions, and cannot meet the working requirements of the probe. Comparative Example 10 uses a 0.5% sodium chloride solution, although no crystals are formed during the experiment, bacteria are easily produced in the solution, and after several experiments, the storage time is 3 days. Therefore, the sodium chloride solution has a short storage time and cannot meet the requirements. Comparative Example 11 uses a 0.5% sodium chloride and 0.1% potassium permanganate mixed solution. When potassium permanganate is added to the solution, the liquid turns purple, which causes the probe to be damaged and affects the accuracy of the probe during detection, so it does not meet the requirements. Comparative Example 12 uses a 0.5% sodium chloride and 0.2% boric acid mixed solution. Boric acid can play a sterilizing role to avoid bacteria in the electrolyte, but the mixed solution of sodium chloride and boric acid will have a small amount of crystals, so it also does not meet the requirements. Comparative Example 13 uses a 0.5% sodium chloride, 0.2% boric acid, and 5% sodium sulfate mixed solution. The solution produces flocculation, which causes the mixed solution to be unable to protect the electrolyte of the probe. Comparative Example 14 uses a 0.5% sodium chloride, 0.2% boric acid, and 15% magnesium sulfate mixed solution. The mixed solution does not form crystals for fifteen days, which greatly extends the crystal formation time, but the probe is slightly corroded, so it also does not meet the requirements. Comparative Example 15 uses a 0.5% sodium chloride, 0.2% boric acid, and 30% magnesium sulfate mixed solution. Compared with Comparative Example 14, the concentration of magnesium sulfate is increased. The mixed solution does not form crystals for thirty-five days, which greatly improves the effect of inhibiting crystals compared with Comparative Example 14, but the probe is still slightly corroded. Comparative Example 16 uses a 0.5% sodium chloride, 0.2% boric acid, 30% magnesium sulfate, and 2% sodium dehydroacetate mixed solution. Compared with Comparative Example 15, sodium dehydroacetate is added to prevent corrosion. The mixed solution does not form crystals for ninety days, which further improves the effect of inhibiting crystals, but the probe is still corroded. Examples 1-5 replace sodium dehydroacetate with cyclododecylpropanol on the basis of Comparative Example 16, which can inhibit crystallization and protect the probe. It can be understood that cyclododecylpropanol can also be replaced by, for example, benzoic acid, sodium benzoate, potassium sorbate, or calcium propionate.
