Description

Technical Field

[0001] The present application relates to the technical field of measuring instruments, and more specifically, to an automatic heating, dissolution-aiding and stirring device for a moisture tester. Background Art

[0002] The principle of the moisture tester is to extract the moisture from the sample first and then measure the moisture.

[0003] The basic principle of existing moisture testers is that the moisture in the sample reacts with the Karl Fischer reagent, and the waste liquid needs to be discharged after the moisture test is completed. However, for the moisture test of some samples that are difficult to dissolve at room temperature, the moisture in the sample is difficult to release, for example, the moisture test of samples that are difficult to dissolve at room temperature, such as chocolate and sugar, and the discharge of waste liquid with high viscosity after the moisture test is completed, such as sugar water, polyurethane solution or epoxy resin adhesive liquid. Existing moisture testers cannot meet the needs of testing these samples that are difficult to dissolve at room temperature and discharging waste liquid after the test is completed. Utility Model Content

[0004] In view of the shortcomings of the prior art, the purpose of this application is to provide an automatic heating and dissolution-aiding stirring device for a moisture tester. For the moisture test of insoluble samples at room temperature, the insoluble samples are heated while being stirred, thereby accelerating the dissolution rate of the insoluble samples, making it easier to release the moisture in the samples and improving the efficiency of discharging waste liquid.

[0005] To achieve the above objectives, this application provides the following technical solutions:

[0010] A temperature control module connected to the heating module is used to adjust the temperature of the heat-conducting container according to a preset temperature so that the temperature in the sample bottle is within a preset range, thereby facilitating the melting of the sample for moisture testing;

[0011] The stirring speed control module is used to adjust the stirring speed of the sample in the sample bottle according to a preset stirring speed so that the sample is heated evenly.

[0012] Furthermore, the material of the heat-conducting container is aluminum alloy.

[0013] Furthermore, the cavity of the heat-conducting container is in the shape of a wedge-shaped hole, and the larger opening of the wedge-shaped hole extends toward the direction in which the sample bottle extends into the cavity of the heat-conducting container.

[0014] Furthermore, the smaller inner hole surface of the wedge-shaped hole of the heat-conducting container is matched with the bottle wall surface of the sample bottle with a very small gap.

[0015] Furthermore, the stirring speed control module includes a speed regulating knob, and the speed regulating knob is used to convert the rotation position signal into a voltage signal, so that the stirring speed control module generates a stirring speed signal according to the voltage signal.

[0016] Furthermore, the automatic heating, dissolution-aiding and stirring device for the moisture tester further comprises:

[0017] A bracket is fixedly arranged on the thermally conductive container, wherein the bracket is provided with a clamping portion, and the clamping portion is configured to fix the sample bottle in the thermally conductive container during a moisture test.

[0025] This application has at least the following beneficial effects:

[0026] The heating module provides heat energy to the thermal container, which transfers the heat to the sample bottle.

DETAILED DESCRIPTION

[0032] In order to make the purpose, technical solution and advantages of the present application clearer, the technical solution of the present application will be clearly and completely described below in combination with the specific embodiments of the present application and the corresponding drawings. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present application.

[0033] Please refer to Figure 1 The present application provides an automatic heating, dissolution-aiding and stirring device 100 for a moisture tester, comprising:

[0034] A heat-conducting container 2 with an opening on one side is provided, and the heat-conducting container 2 is provided with a cavity for accommodating the sample bottle 1;

[0035] A heating module 3 detachably connected to the heat-conducting container 2, the heating module being used to provide heat energy;

[0036] A stirring component 4 disposed on the heat-conducting container 2, the stirring component 4 is used to stir the sample in the sample bottle 1;

[0037] The temperature control module 5 connected to the heating module 3 is used to adjust the temperature of the heat-conducting container 2 according to a preset temperature, so that the temperature in the sample bottle 1 is within a preset range, thereby facilitating the melting and discharge of the sample;

[0038] The stirring speed control module 6 is used to adjust the stirring speed of the sample in the sample bottle 1 according to a preset stirring speed so that the sample is heated evenly.

[0039] In the present application, the heat-conducting container 2 can be a cylindrical shape with one end open. The axis of the heat-conducting cup is specifically arranged along the direction of gravity. The automatic heating, dissolution-aiding and stirring device 100 for a moisture tester also includes a base. The heat-conducting cup is fixedly arranged on the base. The stirring assembly 4 is arranged at the bottom of the heat-conducting cup. The heating module 3 converts electrical energy into thermal energy. The heating module 3 is specifically a heating rod.

[0040] The temperature control module 5 is specifically a chip storing a temperature control program. The temperature control module 5 is connected to the heating rod via a wire. The stirring speed control module 6 is specifically a circuit board storing a stirring speed control program. The stirring speed control module 6 is connected to the stirring assembly 4 via a wire.

[0041] The temperature control module 5 is also electrically connected to the stirring speed control module 6, so that the stirring assembly 4 controls the stirring speed according to the temperature of the sample, or the heating temperature of the heating rod is set according to the stirring speed of the sample. The detachable connection between the heating rod and the heat-conducting container 2 can be a bolt connection or a clamping connection.

[0042] It is understandable that during the use of existing moisture testers, samples with high viscosity such as sugar and chocolate are solid at room temperature, which is not conducive to moisture testing and waste liquid discharge after the test. Therefore, for the moisture test of samples that are difficult to dissolve at room temperature, the automatic heating and dissolution-aiding stirring device of the utility model has a heating and stirring function. During the moisture test, the samples that are difficult to dissolve at room temperature are heated to the dissolution temperature, for example, the temperature is heated to 50°C, so that the moisture test can be carried out after the sample is dissolved. It should be particularly noted that in the utility model, samples that are difficult to dissolve at room temperature are solid or semi-solid at room temperature and need to be heated before they can become liquid.

[0043] When the sample to be tested is a poorly soluble sample at room temperature, the heating of the poorly soluble sample at room temperature can be achieved by controlling the opening of the temperature control module. Of course, if the sample to be tested is a sample that is easily soluble at room temperature, the temperature control module does not need to be turned on.

[0044] The heating rod of the present application generates heat to provide heat for the thermal cup, so that the temperature of the thermal cup increases, thereby increasing the temperature in the sample bottle 1. The viscosity of the sugar water, polyurethane solution or epoxy resin adhesive liquid in the sample bottle 1 decreases with the increase of temperature, which accelerates the release of water in the sample to facilitate moisture testing. After the test is completed, it is convenient for waste liquid to be discharged from the sample bottle 1, increasing the efficiency of the device to discharge waste liquid. Furthermore, the stirring component 4 accelerates the flow rate of the sample, which not only heats the sample evenly, ensures that the water is fully released, and improves the accuracy of moisture detection, but also accelerates the heating rate of the sample, reduces the time of moisture release, and improves the efficiency of moisture testing. Furthermore, the detachable connection between the heating rod and the thermally conductive container 2 facilitates the installation and disassembly of the heating rod when the maintenance device is used. When the model of the heating rod is changed according to the heating demand, it is convenient to replace the heating rod without replacing the thermally conductive container 2, saving costs.

[0045] In one embodiment provided in the present application, the material of the heat-conducting container 2 is aluminum alloy.

[0046] In the present application, aluminum alloy has the characteristic of fast heat conduction. It is understandable that the heat-conducting cup made of aluminum alloy accelerates the heating speed of the whole cup, accelerates the heating of the sample bottle 1, reduces the time of water release, improves the efficiency of water detection, and also improves the efficiency of waste liquid discharge.

[0047] In one embodiment provided in the present application, the cavity of the heat-conducting container 2 is in the shape of a wedge-shaped hole, and the larger mouth of the wedge-shaped hole extends into the direction of the cavity of the heat-conducting container 2 toward the sample bottle 1 .

[0048] Specifically, the wedge-shaped hole can be a hole with a circular cross section. The inner hole surface of the wedge-shaped hole is specifically an inner truncated cone hole surface. The axis of the wedge-shaped hole is arranged along the gravity direction. The smaller opening of the wedge-shaped hole is specifically the cup bottom of the thermal conductive container 2. The larger opening of the wedge-shaped hole is arranged upward along the gravity direction. The sample bottle 1 extends from the top opening of the thermal conductive cup into the wedge-shaped hole of the thermal conductive cup.

[0049] It can be understood that the inclined inner surface of the wedge-shaped hole guides the sample bottle 1 to the bottom center of the heat transfer cup, avoiding uneven heating of the sample bottle 1 due to the small distance between the sample bottle 1 and the side wall of the heat transfer cup and the large distance in another part, thereby ensuring that the sample is evenly heated and improving the efficiency of moisture testing.

[0050] In one embodiment provided in the present application, a small clearance is provided between the inner surface of the smaller opening of the wedge-shaped hole of the heat-conducting container 2 and the wall surface of the sample bottle 1 .

[0051] It can be understood that a very small gap is left between the sample bottle 1 and the smaller mouth of the wedge-shaped hole of the thermal cup, which not only ensures that the sample bottle 1 can extend into the bottom of the thermal cup and fully contact the bottom of the cup to increase the heating area, but also reduces the distance between the sample bottle 1 and the side wall of the thermal cup near the bottom, reduces heat loss, and improves the efficiency of heat transfer, thereby increasing the heating speed of the sample, improving the water evaporation efficiency, and improving the water testing efficiency.

[0052] In one embodiment provided in the present application, the stirring speed control module 6 includes a speed knob, and the speed knob is used to convert the rotation position signal into a voltage signal, so that the stirring speed control module 6 generates a stirring speed signal according to the voltage signal.

[0053] It is understandable that the speed knob can be a cylindrical knob. The cylindrical structure of the speed knob itself is convenient for manual rotation, and it is convenient to adjust the stirring speed. The speed knob generates different voltage signals when it is rotated to different positions, which has a simple structure, low manufacturing cost and is easy to use.

[0054] In one embodiment provided in the present application, the automatic heating and stirring device of the moisture tester further includes:

[0055] The support 7 is fixedly arranged on the heat-conducting container 2 , and the support 7 is provided with a clamping portion 71 . The clamping portion 71 is configured to fix the sample bottle 1 in the heat-conducting container 2 during the water content test.

[0056] In the present application, the clamping part 71 can be specifically a flask clamp. It is understandable that the clamping part 71 fixes the sample bottle 1 in the heat-conducting container 2 to avoid leakage of the sample caused by the sample bottle 1 tipping over during the stirring process, thereby polluting the environment and ensuring the accuracy of the water content measurement.

[0057] In one embodiment provided in the present application, the stirring assembly 4 includes:

[0058] A stirring member 41 is disposed in the sample bottle 1, and the material of the stirring member 41 is a magnet;

[0059] The electromagnetic coil 42 is disposed adjacent to the sample bottle 1 and is configured to rotate the stirring member 41 when energized.

[0060] In the present application, the electromagnetic coil 42 is specifically an electric wire spirally arranged at the bottom of the heat-conducting container 2. The electromagnetic coil 42 is electrically connected to the stirring speed control module 6. It is understandable that the stirring member 41 made of a magnet is magnetic. The electromagnetic coil 42 is magnetic when powered on. The alternating current produces a changing magnetic field, and the magnetic force between the changing magnetic field and the stirring member 41 changes. The stirring member 41 moves under the action of the changing magnetic force, which can drive the sample to move and achieve stirring of the sample. During the test, there is no need to open the sample bottle 1 to stir the sample, and all moisture can be collected to improve the accuracy of the moisture test. In addition, in the process of pouring out the waste liquid in the sample bottle 1, the stirring member 41 continues to stir the sample in the magnetic field range of the electromagnetic coil 42, following the movement of the sample bottle 1, to facilitate the discharge of the waste liquid.

[0061] In one embodiment provided in the present application, the automatic heating and stirring device of the moisture tester further includes:

[0062] A power interface connected to the temperature control module 5, used to connect to an external power supply device;

[0063] A power control switch 8 connected to the power interface is configured to power on the temperature control module 5, the stirring speed control module 6, the stirring assembly 4, and the heating rod when closed.

[0064] Specifically, the power interface is also electrically connected to the stirring assembly 4, the stirring speed control module 6, and the heating module 3. It can be understood that the power interface is a connection port between the automatic heating device and the external power supply device to realize the power supply to the automatic heating device. When the power control switch 8 is closed, the device is prevented from being damaged by an inappropriate voltage at the moment when the power interface is connected to the external power supply device, thereby protecting the device and extending its service life.

[0065] In one embodiment provided in the present application, the temperature control module 5 includes a temperature sensor for obtaining the temperature of the heat-conducting container 2, a display screen for displaying the temperature, and a control panel for sending temperature control instructions.

[0066] Specifically, the temperature control module 5 also includes a temperature control chip connected to the temperature sensor. The chip stores a temperature control program. The temperature sensor transmits temperature data to the temperature control chip. The temperature control chip outputs a temperature control instruction based on the temperature data and the temperature control program. The temperature control chip can also output a temperature control instruction based on the temperature data input by the control panel to control the temperature in the sample bottle 1. The control panel can manually input temperature data to facilitate the control of the sample temperature. The display screen makes it easy for people to know the temperature of the heat-conducting container 2, which is convenient to use.

[0067] Although the preferred embodiments of the present application have been described, those skilled in the art may make other changes and modifications to these embodiments once they have learned the basic creative concept. Therefore, the appended claims are intended to be interpreted as including the preferred embodiments and all changes and modifications falling within the scope of the present application.

[0068] Obviously, those skilled in the art can make various changes and modifications to the present application without departing from the spirit and scope of the present application. Thus, if these modifications and variations of the present application fall within the scope of the claims of the present application and their equivalents, the present application is also intended to include these modifications and variations.
