[0022] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0023] Example 1:

[0024] like Figures 1-9 As shown, this utility model discloses a laboratory chemical product testing device, including a main frame 1, a magnetic ultrasonic host 4, and a replaceable coupling plate 5. The magnetic ultrasonic host 4 is located below the main frame 1. The replaceable coupling plate 5 is located between the magnetic ultrasonic host 4 and the main frame 1. A test sleeve 11 is located inside the main frame 1 above the replaceable coupling plate 5. A test cylinder 12 is located inside the test sleeve 11. The test sleeve 11 is used to cool or heat the test cylinder 12. A sealing cover 2 is located on the main frame 1 at the top of the test sleeve 11. The sealing cover 2 is used to seal the test cylinder 12. A test probe 21 is located on the lower surface of the sealing cover 2 and extends into the test cylinder 12.

[0025] The main frame 1 is used to assemble and connect various components, serving as a support carrier; its specific structural shape is not limited. The interior of the main frame 1 can be filled with flame-retardant ultrasonic adsorption material, such as flame-retardant foam. Below the main frame 1 is a magnetic ultrasonic host 4 and a replaceable coupling plate 5. The magnetic ultrasonic host 4 and replaceable coupling plate 5 are existing commercially available products; their specific structures are not described in detail. The magnetic ultrasonic host 4 has a magnetic stirring function module and an ultrasonic generator module. The replaceable coupling plate 5 can be an ultrasonic converter function plate or a magnetic stirring tray. When the replaceable coupling plate 5 uses a magnetic stirring tray, a magnetic stirring rotor 13 can be placed inside the test cylinder 12. Under the action of the magnetic stirring function module activated by the magnetic ultrasonic host 4, the material inside the test cylinder 12 is stirred. The test cylinder 12 is an upward-opening barrel with a closed bottom. The test sleeve 11 can heat or cool the test cylinder 12, while the sealing cover 2 can seal the test cylinder 12. At the same time, the lower surface of the sealing cover 2 is provided with a test probe 21, which extends into the interior of the test cylinder 12. The test probe 21 can be one or more, such as a temperature sensor, a pressure sensor, etc., which can be set according to actual needs.

[0026] The sealing cover 2 and the main frame 1 can be connected by an interlock switch 15 to ensure a tight connection between them. The lower surface of the sealing cover 2 can be provided with a downwardly protruding boss 20, which is consistent with the opening structure of the test cylinder 12. The boss 20 is inserted into the test cylinder 12 to seal the test cylinder 12. Of course, a sealing ring can be provided around the boss 20 to improve the sealing effect between the sealing cover 2 and the test cylinder 12.

[0027] The testing device in this embodiment can be equipped with a controller, and a main unit panel can be installed on the main frame 1. The main unit panel is connected to the controller, and the controller is operated by the main unit panel. The controller controls the operation of the magnetic ultrasonic host 4, the replaceable coupling plate 5, the test sleeve 11, the sealing cover 2, and the interlock switch 15.

[0028] Inside the sealing cover 2, one or more of the following are provided: nitrogen pipe 22, vent pipe 23, washing pipe 24, and vacuum pipe 25. One end of the nitrogen pipe 22, vent pipe 23, washing pipe 24, and vacuum pipe 25 extends into the sealing cover 2 area corresponding to the test cylinder 12, and the other end extends to the side wall of the sealing cover 2 to form a nitrogen interface 26, a vent interface 27, a washing interface 28, and a vacuum interface 29. Solenoid valves are provided in the nitrogen pipe 22, vent pipe 23, washing pipe 24, and vacuum pipe 25.

[0029] To meet the requirements of the testing environment, this embodiment includes four pipes inside the sealing cover 2: a nitrogen pipe 22, a vent pipe 23, a washing pipe 24, and a vacuum pipe 25. One end of each of these four pipes extends into the sealing cover 2 corresponding to the test cylinder 12, specifically into the interior of the boss 20. Thus, in actual use, after the sealing cover 2 is sealed to the test cylinder 12, the nitrogen port 26, vent port 27, washing port 28, and vacuum port 29 are all connected to the test cylinder 12. The nitrogen port 26 can be connected to a nitrogen source, allowing nitrogen to be introduced into the test cylinder 12 when a nitrogen environment is required for testing the materials inside. The vent port 27 can be connected to an exhaust gas pipe; if exhaust gas is generated during sample testing, it can be directly discharged into the exhaust gas pipe and transported to the exhaust gas treatment system. The washing port 28 can be connected to a washing liquid tank, where a water pump delivers washing liquid into the test cylinder 12. The washing liquid is then agitated by the magnetic stirring rotor 13, thus cleaning the test cylinder 12. If the sample needs to be tested in a vacuum environment, a vacuum pump can be connected to the vacuum interface 29 to evacuate the inside of the test cylinder 12. Solenoid valves are installed in all four pipes, which are used to close or open the corresponding pipes to maintain a stable testing environment.

[0030] The structure of the test sleeve 11 is as follows: it includes a heating sleeve 16, axial flow channels 18 are spaced apart on the heating sleeve 16, ceramic heat-conducting plates 17 are embedded on the heating sleeve 16 between adjacent axial flow channels 18, a cylinder protective sleeve 19 is provided inside the heating sleeve 16, and annular heat insulation layers are provided at both ends of the heating sleeve 16. A circumferential flow channel is provided inside the heat insulation layer. The axial flow channel 18 is connected to the circumferential flow channel. The axial flow channel 18 and the circumferential flow channel form a refrigerant channel. The refrigerant channel is connected to the side wall of the main frame 1 through a pipe to form a refrigerant inlet 8 and a refrigerant outlet 9.

[0031] The heating sleeve 16 is capable of heating and can be made of composite materials such as alloy wire springs, alkali-free glass fiber, and aluminum silicate cotton, enabling electric heating. The insulation layers at both ends are primarily used to create circumferential flow channels, allowing the axial flow channels 18 to connect and form refrigerant channels. A ceramic heat-conducting plate 17 is installed inside the heating sleeve 16 between the axial flow channels 18. The thickness of the heating sleeve 16 is reduced where the ceramic heat-conducting plate 17 is located, allowing the ceramic heat-conducting plate 17 to be embedded in the heating sleeve 16, while maintaining the flatness of the inner and outer walls of the entire test sleeve 11. The refrigerant channel connects to the side wall of the main frame 1, forming a refrigerant inlet 8 and a refrigerant outlet 9, enabling refrigerant circulation within the test sleeve 11 to cool the test cylinder 12 when needed. If heating of the test cylinder 12 is required, the heating sleeve 16 is used for heating, and the heat is transferred to the test cylinder 12 via the ceramic heat-conducting plate 17. The ceramic heat-conducting plate 17 adopts a vertical plate shape to achieve uniform heat transfer. At the same time, it may contain a multi-pore structure to absorb and scatter the ultrasonic waves generated by the magnetic ultrasonic host 4, preventing the ultrasonic waves from escaping. The cylinder protective sleeve 19 is made of stainless steel and coated with a wear-resistant coating with good thermal conductivity on both the inside and outside.

[0032] It also includes an auxiliary mechanism 3, which is mounted on the main frame 1. The auxiliary mechanism 3 includes a frequency converter 30, and a mounting frame 31 is provided on the frequency converter 30 for mounting the stirring rotor 13. When continuous and stable stirring of the sample in the test cylinder 12 is required, the auxiliary mechanism 3 can be used. The test cylinder 12 is removed and placed under the auxiliary mechanism 3, and the stirring rotor 13 on the frequency converter 30 of the auxiliary mechanism 3 extends into the test cylinder 12. The frequency converter 30 is then started, allowing the stirring rotor 13 to continuously and stably stir the sample in the test cylinder 12. Of course, a stirring rotor 13 of a suitable shape can be selected and installed on the mounting frame 31 according to actual needs. The stirring rotor 13 can be made of metal or non-metal.

[0033] A rotor guard 14 is provided on the mounting frame 31. When rotational viscosity measurement is required, the rotor guard 14 is assembled and used with different stirring rotors 13 to measure samples with different viscosity ranges.

[0034] A lifting platform 7 is installed on the main frame 1 below the auxiliary mechanism 3. Since the height of the auxiliary mechanism 3 remains constant, the lifting platform 7 can be used to adjust the height of the test cylinder 12 so that the test cylinder 12 and the stirring rotor 13 of the auxiliary mechanism 3 are properly matched. The lifting platform 7 can adopt a shear-folding structure. The lifting platform 7 is a known existing structure and will not be described in detail.

[0035] A counterweight 6 is provided on the main frame 1. One side of the counterweight 6 is recessed to form a trapezoidal groove 10. The trapezoidal groove 10 extends vertically through the counterweight 6. The lifting platform 7 is located in the trapezoidal groove 10 of the counterweight 6.

[0036] The counterweight 6 is set to maintain the stability of the entire device, and at the same time, it can keep the test cylinder 12 below the auxiliary mechanism 3 stable during the stirring process.
