Specific meanings of the above terms in the embodiments of the present application can be understood in specific cases by those of ordinary skill in the art.

The embodiment of the application discloses a moisture measuring instrument auxiliary device and a method.

Referring to fig. 1, an auxiliary device of a moisture meter provided in an embodiment of the present application includes: vacuum pump 1, three-way valve 2, controller (not shown), reagent bottle 3, waste oil bottle 4, electrolysis bottle 5, first pipe 6 and second pipe 7.

The waste oil bottle 4 is arranged in a sealing way, oil liquid is contained in the waste oil bottle, and the inner part of the waste oil bottle is divided into an oil liquid area and a gas area; the reagent bottle 3 is arranged in a sealing way and contains reagents; the electrolytic bottle 5 is internally provided with a reagent and oil floating on the reagent.

The three-way valve 2 has a first end 21 connected to the vacuum pump 1, a second end 22 connected to the inside of the reagent bottle 3, and a third end connected to the gas area of the waste oil bottle 23. The first end of the first conduit 6 extends into the waste oil bottle 4, and the second end extends into the electrolytic bottle 5 and is positioned at a first preset height; the first preset height is the reagent height when the reagent in the electrolytic bottle 5 is a test required value; the first end of the second conduit 7 extends into the bottom of the reagent bottle 3, and the second end extends into the bottom of the electrolytic bottle 5; the controller is connected with the vacuum pump 1 and the three-way valve 2 and is used for controlling the starting and stopping of the vacuum pump 1 and controlling the opening and closing of the first end, the second end and the third end of the three-way valve 2.

Specifically, the vacuum pump 1 can control the air pressure inside the reagent bottle 3 and the waste oil bottle 4 through the three-way valve 2. When the vacuum pump 1 inflates the reagent bottle 3, the reagent in the reagent bottle 3 is supplied to the second conduit 7 by the increasing gas pressure, so that the reagent can be supplied to the electrolytic bottle. When the vacuum pump 1 sucks air into the waste oil bottle 4, the air pressure in the waste oil bottle 4 is reduced to suck the waste oil in the electrolytic bottle 5 into the waste oil bottle.

The first preset height corresponds to a test requirement value of a reagent in the electrolytic bottle 5, so that the height is oil upwards and the height is the reagent downwards. Correspondingly, with the progress of the moisture measurement test, the reagent in the electrolytic bottle 5 is gradually reduced, and when the reagent height in the electrolytic bottle 5 is lower than the first preset height, the reagent can be supplemented through the reagent bottle 3, so that the reagent in the electrolytic bottle 5 is ensured to meet the requirement of the test requirement value, and the test accuracy is prevented from being influenced.

It should be noted that the reagent used in the moisture measurement test is generally a reagent of karya, which affects the life of a person when the reagent comes into contact with a human body. By the aid of the auxiliary device for the moisture measuring instrument, reagents can be automatically supplemented, the possibility that workers contact the Karl Fischer's reagent is reduced, and accordingly the incidence rate of safety accidents is reduced; moreover, the oil in the electrolytic bottle 5 is sucked, so that the worker does not need to frequently clean the electrolytic bottle 5, and the work load of the worker is reduced.

Further, the device also comprises an electromagnetic valve 11; the electromagnetic valve 11 is arranged on the electrolytic bottle 5; the controller is electrically connected with the electromagnetic valve 11 and is used for controlling the conduction or the isolation of the electrolytic bottle 5 and the external atmosphere by controlling the opening and the closing of the electromagnetic valve 11.

Specifically, when the controller adjusts the volume of the oil and the reagent in the electrolytic bottle 5, the electromagnetic valve 11 is opened to keep the air pressure in the electrolytic bottle 5 balanced.

Further, a dryer 12 is also included; both ends of the dryer 12 are connected to a first end of the three-way valve 21 and the vacuum pump 1, respectively.

In the embodiment, the dryer 12 is a silica gel dryer, and may be a container capable of containing silica gel desiccant, which has good overall sealing performance, and the container can be conveniently opened and closed by a worker to replace the desiccant. The dryer 12 is used to dry the gas inside the duct, reducing the effect of moisture on the vacuum pump 1.

Further, still include: a fuel level sensor 8; the oil level sensor 8 is disposed at a first end of the first conduit 6, and is connected to the controller for sensing the height of the oil in the waste oil bottle 4.

Therefore, when the oil in the waste oil bottle 4 is too high, a prompt can be sent; the staff can change the waste oil bottle according to reminding.

It should be noted that the manner of the controller sending out the reminder may be connected to a display screen for display or an alarm sent out by an alarm.

Further, still include: a flow sensor 9; the flow sensor 9 is disposed on the first conduit 6, and is connected to the controller, for sensing the oil flow of the first conduit 6.

Specifically, the controller senses the oil quantity of the first conduit 6 through the flow sensor 9, so that the oil storage quantity in the electrolytic bottle 5 can be judged, and when the flow of the flow sensor 9 is lower than a preset flow value, the oil quantity in the electrolytic bottle 5 is indicated to meet the requirement, so that the next operation of supplementing the reagent or a moisture measurement test can be directly carried out.

Further, still include: a mass sensor 10; the quality sensor 10 is arranged at the bottom of the electrolytic bottle 5 and is connected with the controller for sensing the height of the liquid in the electrolytic bottle 5.

Specifically, the mass sensor 10 is configured to sense the weight of the reagent after the oil in the electrolytic bottle 5 is completely sucked, determine whether the reagent in the electrolytic bottle 5 satisfies the test requirement, and feed back the result to the controller, and if not, replenish the reagent in the electrolytic bottle 5 through the reagent bottle 3.

Further, the first conduit is a glass conduit, avoiding reaction with the reagent.

Further, the second conduit is a polytetrafluoroethylene conduit.

The first embodiment provided above is an embodiment 2 provided below, and a second aspect of the present application provides a method for assisting a moisture meter, which is applied to the device for assisting a moisture meter according to any one of the above embodiments;

this moisture content measuring apparatu auxiliary device includes:

the device comprises a vacuum pump 1, a three-way valve 2, a controller, a reagent bottle 3, a waste oil bottle 4, an electrolytic bottle 5, a first conduit 6 and a second conduit 7;

the method comprises the following steps:

s1, the controller judges whether the oil level in the waste oil bottle 4 is higher than a second preset level, if not, the step S2 is executed;

the controller determines the oil level of the waste oil bottle 4 by arranging an oil level sensor 8 at the first end of the first conduit 6, so as to sense the oil level in the waste oil bottle 4; if the height is higher than the second preset height, the waste oil bottle is prompted to be replaced, and if not, the next step can be carried out.

Correspondingly, the second preset height can be set according to actual needs without limitation.

S2, the controller controls the first end 21 and the third end 23 of the three-way valve 2 to be opened and the second end 22 to be closed, then the vacuum pump 1 reduces the air pressure in the waste oil bottle 4, so that the oil in the electrolytic bottle 5 flows into the waste oil bottle 4 along the first conduit 6 until the oil in the electrolytic bottle 5 is lower than the preset volume, and the step S3 is performed;

the mode that the controller judges that the oil in the electrolytic bottle 5 is lower than the preset volume can be that the flow sensor 9 is arranged on the first conduit 6, when the flow sensor 9 senses that the flow in the first conduit 6 is lower than the preset flow value, it indicates that the second end of the first conduit 6 cannot absorb enough oil, and further the oil in the electrolytic bottle 5 is lower than the preset volume, and then the next step can be carried out.

S3, the controller judges whether the reagent in the electrolytic bottle 5 meets the preset range, if not, the first end 21 and the second end 22 of the three-way valve 2 are controlled to be opened, the third end 23 is controlled to be closed, and then the air pressure in the reagent bottle 3 is increased through the vacuum pump 1, so that the reagent in the reagent bottle 3 flows into the electrolytic bottle 5 along the second conduit 7 until the reagent in the electrolytic bottle 5 meets the preset range.

The controller judges whether the reagent in the electrolytic bottle 5 meets the preset range, and can sense the height of the liquid left after the oil is absorbed by arranging a liquid level sensor and the like in the electrolytic bottle 5; in this embodiment, be through the mode that sets up quality sensor 10 in the bottom of electrolysis bottle 5, thereby to the quality of remaining liquid after fluid is absorbed in the electrolysis bottle thereby judge whether the interior reagent of electrolysis bottle 5 satisfies preset range, if unsatisfied, then supply reagent through reagent bottle 3, if satisfy, then can show through devices such as display screen: the test conditions are satisfied, and the like, which indicates that the moisture measurement test can be performed.

By the aid of the auxiliary method for the moisture measuring instrument, automatic operation can be achieved, so that the device meets the pre-test requirements of a moisture measuring test, and the moisture measuring instrument can be balanced more quickly in the test process due to the fact that waste oil does not exist in the electrolytic bottle 5, so that working efficiency is improved, and accuracy of a measuring result is improved; moreover, the oil in the electrolytic bottle 5 can be automatically sucked, the reagent can be automatically supplemented, the workload of workers for cleaning the electrolytic bottle 5 and the probability of the workers contacting the reagent can be reduced, and therefore the safety of the test is improved.

Although the present invention has been described in detail with reference to examples, it will be apparent to those skilled in the art that various changes may be made and equivalents may be substituted for elements thereof without departing from the scope of the invention.
