[0001] The utility model relates to the technical field of liquid combustion, in particular to a liquid continuous combustion tester. Background Technique

[0002] Liquid is one of the three major states of matter. It has no definite shape and is often affected by the container. However, its volume remains fixed in an environment with constant pressure and temperature. The distance between liquid molecules is relatively far, the molecular movement is relatively intense, and the attraction between molecules is relatively small. Combustion is a process in which an object rapidly oxidizes, generating light and heat. The essence of combustion is an oxidation-reduction reaction. In a broad sense, combustion does not necessarily require the participation of oxygen. Any luminous, heat-generating, and intense oxidation-reduction reaction can be called combustion. Therefore, a liquid continuous combustion tester is needed.

[0003] When operators conduct combustion tests on liquids, they often use corresponding liquid continuous combustion testers. Although existing instruments can achieve the purpose of combustion tests, in actual test processes, the sample tanks for holding liquids are mostly fixedly installed, which is inconvenient to replace and cannot meet the test work of different liquids. Moreover, the degree of automation of the instruments is low, and the practicality is reduced. Content of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0018] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0019] Please refer to Figures 1-4 , the present invention provides a technical solution: a liquid continuous combustion tester, including an instrument body 1, which is embedded with an industrial control PC main board and a 10.1-inch capacitive touch screen, uses the Windows7 operating system, pre-installs professional operation software, supports wireless networking, and a single computer can remotely control multiple instruments through a wireless network, and realizes centralized storage and management of data, thereby improving its automation degree. A detection module 2 is fixedly installed on the top of the instrument body 1 for detection work. A test sample plate 3 is movably installed on the top of the instrument body 1 on the right side of the detection module 2. The material of the test sample plate 3 is aluminum alloy and stainless steel. Aluminum alloy is an alloy with aluminum as the base and a certain amount of other alloying elements added, and it is one of the light metal materials. A steel type that is resistant to weak corrosive media such as air, steam, and water or has stainless properties is called stainless steel. A sample groove 4 is opened on the top of the test sample plate 3. The sample groove 4 is divided into an aluminum alloy sample groove and a stainless steel sample groove. The aluminum alloy sample groove has good thermal conductivity, and the stainless steel sample groove is used to hold samples with high viscosity, which is convenient for cleaning but has poor thermal conductivity. When the viscosity of the sample itself is not very high, the aluminum alloy sample groove is generally selected. A handle 5 is fixedly installed on the top of the test sample plate 3, and the handle 5 facilitates the rotation of the test sample plate 3. And an ignition needle 6 is fixedly installed on the top of the instrument body 1 for ignition work. The material of the ignition needle 6 is silicon nitride. Silicon nitride is an important structural ceramic material, with high hardness, lubricity itself, and wear resistance. It is an atomic crystal, resistant to oxidation at high temperatures, and it can also resist thermal shock. When heated to more than 1000 °C in the air, cooled rapidly and then heated rapidly, it will not break. A level 7 is fixedly installed on the top of the instrument body 1. The working principle of the level 7 is based on the principle of hydrostatics. Under the action of gravity, the liquid generates different liquid levels in the container. When the level 7 is in a horizontal state, the liquid levels at both ends of the observer are equal, and the bubble is located at the midpoint. When the level 7 is tilted, the liquid levels are different, and the bubble will move to the tilted direction, indicating the deviation degree of the level 7, thereby detecting the levelness of the instrument body 1. And an air regulating valve 8 is movably installed on one side of the instrument body 1. The air regulating valve 8 can adjust the size of the flame. This test process is automated, automatically completing ignition, positioning, timing, data recording, and automatically judging the test results. It can also adjust the heating temperature and the sample injection volume, taking into account the standardization and flexibility of the test.

[0020] One end of the instrument body 1 is fixedly installed with a protective frame 9, which can protect the display screen 10. And the display screen 10 is fixedly installed inside the protective frame 9, which can display the detection data. One end of the instrument body 1 is fixedly installed with a switch button 11 on the right side of the protective frame 9. The switch button 11 is used to turn on and off the instrument body 1. And the other end of the instrument body 1 is fixedly installed with an emergency stop switch 12, which can perform an emergency stop with one key and directly cut off the power in case of an accident to ensure the safety of the test personnel. The other end of the instrument body 1 is fixedly installed with a power switch 13, which can control the input of the power supply. And the other end of the instrument body 1 is fixedly installed with a power indicator light 14 on the right side of the power switch 13, which is convenient for observation. The other end of the instrument body 1 is provided with a power interface 15, which is used to connect the power supply. And the other end of the instrument body 1 is fixedly installed with an air switch 16 above the power interface 15. The detection work can be carried out only when the air switch 16 is in the on state.

[0021] Working principle: First, connect the power supply through the power interface 15 and make sure that the air switch 16 is in the on state. Then turn on the power switch 13 on the back of the instrument body 1 and make the power indicator light 14 light up. Subsequently, confirm that the emergency stop switch 12 is in the popped-up state. Press the switch button 11 at one end of the instrument body 1, and the instrument body 1 starts to start. At this time, place the test sample plate 3 on the test platform, then use a 10 mL syringe to take 6 mL of the test liquid and place it inside the sample tank 4. After the sample preparation is completed, automatically ignite through the ignition needle 6 and adjust the flame size through the gas adjustment valve 8. At the same time, the automatic detection can be carried out through the detection module 2 and the detection data can be displayed through the display screen 10.

[0022] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
