Abstract
Description
Technical Field
[0001] This utility model specifically relates to a chemical analysis heating device, belonging to the field of chemical heating technology. Background Technology
[0002] In materials research and industrial and agricultural quality inspection, the observation of heating granular materials and industrial and agricultural scraps is a key chemical analysis method. By monitoring the changes in color and morphology during the heating process, core objectives such as component identification, purity detection, and thermal stability assessment can be achieved, providing important basis for material performance judgment and product quality control.
[0003] The current mainstream method typically involves placing the material in a glass container for fixed heating. The glass container is usually vertical. If the glass container is placed vertically on a heating plate, the heating source only acts on a local area of the glass container, resulting in uneven heating around the tube. This leads to some areas being too hot and others not hot enough. Furthermore, the material inside the tube will accumulate due to gravity. The material at the bottom, which is in prolonged contact with high temperatures, is prone to overheating or even carbonization, while the material at the top is difficult to heat sufficiently, resulting in thermal stratification. This seriously affects the accuracy of observing changes in color and shape after heating, and makes it difficult to truly reflect the thermal stability and compositional characteristics of the material.
[0004] To address the above problems, this application proposes a chemical analysis heating device. Summary of the Invention
[0005] The purpose of this invention is to address the shortcomings of existing technologies by providing a chemical analysis heating device. By integrating drive, lifting, and heating components, multiple sets of materials to be analyzed are first loaded into a glass container. The container is then circumferentially mounted on the front of a rotating plate via a disassembly and assembly component. The lifting component drives the rotating plate to descend, causing the target glass container to enter the arc-shaped groove. The heating plate then initiates heating. During heating, the gear ring and transmission gear drive the glass container to rotate via a linkage shaft, achieving uniform heating of the glass container and preventing material accumulation by rolling within the container. This improves analytical reliability and solves the problems mentioned in the background art.
[0006] A chemical analysis heating device, comprising: The drive assembly includes a rotating plate. Multiple sets of glass containers are evenly arranged circumferentially on the front side of the rotating plate. A disassembly and assembly component is provided on the rear side of each glass container to facilitate easy disassembly and assembly. A gear ring is rotatably mounted on the back of the rotating plate. Multiple sets of transmission gears are circumferentially meshed on the outer side of the gear ring, and each set of transmission gears corresponds to a set of glass containers. The multiple sets of glass containers are rotated synchronously through the transmission between the gear ring and the transmission gears. A rotating component is provided on the rear side of the rotating plate to drive the rotating plate to rotate and switch the multiple sets of glass containers circumferentially. The heating assembly includes a fixing block disposed below a glass container, wherein an arc-shaped groove is formed above the fixing block and a heating plate is installed on the inner wall of the arc-shaped groove; The lifting assembly, located behind the rotating plate, is used to drive the rotating plate to rise and fall, thereby causing the glass container below to rise and fall into / out of the arc-shaped groove.
[0007] In a preferred embodiment, the glass container has an opening at its front end, and a sealing plug is installed inside the opening. An air tube is installed inside the sealing plug, and the front end of the air tube extends outward from the sealing plug.
[0008] In a preferred embodiment, the disassembly and assembly component includes a connecting plate installed at the rear end of the glass container. A threaded block is installed at the rear end of the connecting plate, and a screw cylinder is threadedly connected to the rear end of the threaded block. A linkage shaft is installed at the rear end of the screw cylinder. The rear end of the linkage shaft passes through the rotating plate and is connected to a transmission gear at a corresponding position. The linkage shaft is rotatably connected to the rotating plate.
[0009] In a preferred embodiment, a brake motor is provided on the rear side of one set of transmission gears, and the output shaft of the brake motor is connected to the transmission gears.
[0010] In a preferred embodiment, a drive rod is installed in the middle of the rotating plate, and a stepper motor is provided behind the drive rod. The output shaft of the stepper motor is connected to the rear end of the drive rod.
[0011] In a preferred embodiment, the lifting assembly includes a concave frame located behind the drive rod, a stepper motor installed inside the concave frame, and a set of rear limiting rods slidably connected to the rear two sides of the concave frame. The rear limiting rods are vertically arranged and have an L-shaped structure in their top view. An electric push rod is provided below the concave frame, and the telescopic end of the electric push rod is connected to the concave frame. A set of side limiting blocks are installed on the lower two sides of the concave frame, and side limiting rods are slidably connected inside the side limiting blocks.
[0012] In a preferred embodiment, a base plate is provided below the concave frame. The base plate has a trapezoidal structure that is narrower at the front and wider at the back, and an anti-slip pad is installed at its bottom. The lower ends of the side limiting rod, the rear limiting rod, and the electric push rod are all fixedly connected to the base plate.
[0013] In a preferred embodiment, a fixing block is installed above the base plate, a temperature display is installed on the front side of the fixing block, a controller is installed on one side of the base plate, and the temperature display, heating plate, brake motor, stepper motor and electric push rod are all electrically connected to the controller. The temperature display is electrically connected to the heating plate through a temperature sensor. Beneficial effects
[0014] By designing a drive assembly, a lifting assembly, and a heating assembly, multiple sets of materials to be analyzed are loaded into glass containers. The test tubes are then evenly installed circumferentially in front of the rotating plate using a disassembly and assembly component. Subsequently, the rotating plate is lowered by the lifting assembly, allowing the target glass container below to enter the arc-shaped groove. The material inside the glass container is heated by the heating plate. During the heating process, the gear ring and the transmission gear form a transmission, which drives the glass container to rotate through the linkage shaft. This ensures that the glass container is evenly contacted with the heat source circumferentially, avoiding local overheating or underheating. It also promotes the continuous rolling and dispersion of the material inside the test tube as it rotates, solving the problem of uneven heating caused by the accumulation of materials due to gravity during traditional static heating, and improving the reliability of the analysis results. Staff can observe the color and shape changes of the material in real time during or after heating to determine its thermal properties and complete chemical analysis. After a set of glass containers has been heated and analyzed, the lifting component drives the rotating plate to rise, causing the glass containers to detach from the arc-shaped groove. Then, the drive component drives the rotating plate to rotate, switching the next set of glass containers to be heated to the top of the arc-shaped groove. The lifting component then drives the rotating plate to descend again, starting a new round of heating and analysis, enabling continuous processing of multiple sets of samples and significantly improving analysis efficiency.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0018] Please see Figures 1-6 As shown, a chemical analysis heating device includes: The drive assembly 1 includes a rotating plate 11. Multiple sets of glass containers 12 are evenly arranged circumferentially on the front side of the rotating plate 11. A disassembly and assembly component is provided on the rear side of the glass containers 12 to facilitate the disassembly and assembly of the glass containers 12. A gear ring 16 is rotatably mounted on the back of the rotating plate 11. Multiple sets of transmission gears 17 are circumferentially meshed on the outer side of the gear ring 16. Each set of transmission gears 17 is respectively set to a set of glass containers 12. The multiple sets of glass containers 12 are rotated synchronously through the transmission of the gear ring 16 and the transmission gears 17. A rotating component is provided on the rear side of the rotating plate 11 to drive the rotating plate 11 to rotate and switch the multiple sets of glass containers 12 circumferentially. The heating component 3 includes a fixing block 31 disposed below the glass container 12, an arc-shaped groove is provided above the fixing block 31, and a heating plate 34 is installed on the inner wall of the arc-shaped groove; The lifting assembly 2 is located behind the rotating plate 11 and is used to drive the rotating plate 11 to lift and lower, so as to drive the glass container 12 below to lift and lower into / out of the arc-shaped groove.
[0019] Please see Figures 1-3 As shown, the glass container 12 has an opening at the front end, and a sealing plug 13 is installed inside the opening. A gas tube 111 is installed inside the sealing plug 13, and the front end of the gas tube 111 extends outward from the sealing plug 13. The opening of the glass container 12 is used to load the material to be analyzed. The sealing plug 13 can seal the tube opening to prevent the material inside the tube from leaking out. The gas generated by heating inside the tube can be discharged through the gas tube 111.
[0020] Please see Figures 1-4 As shown, the disassembly and assembly components include a connecting plate installed at the rear end of the glass container 12. A threaded block 19 is installed at the rear end of the connecting plate. A screw cylinder 14 is threadedly connected to the rear end of the threaded block 19. A linkage shaft 110 is installed at the rear end of the screw cylinder 14. The rear end of the linkage shaft 110 passes through the rotating plate 11 and is connected to the transmission gear 17 at the corresponding position. The linkage shaft 110 is rotatably connected to the rotating plate 11. The threaded block 19 and the screw cylinder 14 form a detachable connection structure through threaded engagement, realizing convenient disassembly and assembly of the glass container 12. The linkage shaft 110 can transmit the rotational power of the transmission gear 17 to the glass container 12, driving the glass container 12 to rotate.
[0021] Please see Figures 1-3As shown, a brake motor 112 is provided on the rear side of one set of transmission gears 17. The output shaft of the brake motor 112 is connected to the transmission gear 17. When the brake motor 112 is running, its output shaft can drive the connected transmission gear 17 to rotate. The transmission gear 17 further drives the gear ring 16 to rotate, and the gear ring 16 then drives the other transmission gears 17 to rotate synchronously, ultimately achieving synchronous rotation of all glass containers 12 and ensuring uniform heating. At the same time, the brake motor 112 has a power-off locking function, which can fix the transmission gear 17 when heating stops or when the glass container 12 does not need to rotate, to prevent the glass container 12 from rotating accidentally due to external force.
[0022] Please see Figures 1-3 As shown, a drive rod 15 is installed in the middle of the rotating plate 11, and a stepper motor 18 is provided behind the drive rod 15. The output shaft of the stepper motor 18 is connected to the rear end of the drive rod 15. The stepper motor 18 can drive the drive rod 15 to rotate through the output shaft, thereby driving the rotating plate 11 to rotate in the circumferential direction, which can realize the switching of different groups of glass containers 12.
[0023] Please see Figures 1-3 As shown, the lifting assembly 2 includes a concave frame 21 located behind the drive rod 15. A stepper motor 18 is installed inside the concave frame 21. A set of rear limit rods 22 are slidably connected to the two rear sides of the concave frame 21. The rear limit rods 22 are vertically arranged and have an L-shaped structure in their top view. An electric push rod 24 is provided below the concave frame 21. The telescopic end of the electric push rod 24 is connected to the concave frame 21. A set of side limit blocks 25 are installed on the two lower sides of the concave frame 21, and a side limit rod 23 is slidably connected inside the side limit blocks 25. When the electric push rod 24 extends or retracts, it can drive the concave frame 21 to rise and fall in the vertical direction, and then drive the glass container 12 to rise and fall through the rotating plate 11, so as to realize the action of the glass container 12 entering or leaving the arc-shaped groove.
[0024] Please see Figure 1 , Figure 2 , Figure 3 as well as Figure 6 As shown, a base plate is provided below the concave frame 21. The base plate has a trapezoidal structure that is narrower at the front and wider at the back, so that the container will be in an inclined state when the base plate is placed, which facilitates the exhaust of gas generated by heating inside the container. An anti-slip pad is installed at the bottom of the base plate to increase its anti-slip properties and make it more stable and less prone to sliding. The lower ends of the side limit rod 23, the rear limit rod 22, and the electric push rod 24 are all fixedly connected to the base plate. The rear limit rod 22 and the side limit block 25 cooperate with the side limit rod 23 to limit and guide the lifting trajectory of the concave frame 21.
[0025] Please see Figure 1 , Figure 2 , Figure 3 as well as Figure 5As shown, the fixing block 31 is installed above the base plate, and a temperature display 33 is installed on the front side of the fixing block 31. A controller 32 is installed on one side of the base plate. The temperature display 33, heating plate 34, brake motor 112, stepper motor 18, and electric push rod 24 are all electrically connected to the controller 32. The temperature display 33 is electrically connected to the heating plate 34 through a temperature sensor. The temperature sensor collects the temperature data of the heating plate 34 in real time and transmits the data to the temperature display 33, which is convenient for the staff to intuitively monitor the heating temperature. The controller 32 is the control core of the device. It can receive the temperature information fed back by the temperature display 33 and centrally control the heating power of the heating plate 34, the start, stop and speed of the brake motor 112, the rotation angle of the stepper motor 18, and the extension and retraction stroke of the electric push rod 24, so as to realize the coordinated operation of various functions of the device.
[0026] In practical use, the working principle of this utility model is as follows: During the analysis of the heating process, multiple sets of materials to be analyzed are first loaded into the glass container 12, and then the opening of the glass container 12 is sealed with a plug 13 to prevent material leakage. The next step is to use the threaded connection between the threaded block 19 and the screw barrel 14 to facilitate the loading and unloading of the glass container 12.
[0027] After installation, the controller 32 controls the operation of each electronic component. The electric push rod 24 extends and retracts, causing the concave frame 21 to descend along the path defined by the rear limit rod 22 and the side limit block 25 along the path defined by the side limit rod 23. This, in turn, causes the rotating plate 11 to descend, allowing the target glass container 12 below the rotating plate 11 to enter the arc-shaped groove. Next, the controller 32 controls the heating plate 34 to start heating (the heating plate 34 can be preheated). At this time, the brake motor 112 is controlled to operate, and its output shaft drives the connected transmission gear 17 to rotate. This transmission gear 17 drives the gear ring 16 to rotate, and the gear ring 16 then drives the other transmission gears 17 to rotate synchronously, creating a linkage. Shaft 110 transmits power to make glass container 12 rotate. During this process, under the action of heating plate 34, glass container 12 is heated evenly in the circumference to avoid uneven local heating. At the same time, the material inside the tube continues to roll and disperse as glass container 12 rotates to prevent accumulation (and other unheated glass containers 12 also rotate synchronously to prevent the material inside them from accumulating and to disperse the material). Temperature sensor collects the temperature of heating plate 34 in real time and displays it through temperature display 33. The staff can observe the color and shape changes of the material in real time (or observe after heating) to complete the analysis. During the heating process, hot air inside the tube can be discharged to the outside through air pipe 111. After a set of glass containers 12 are heated, the electric push rod 24 drives the rotating plate 11 to rise, causing the glass containers 12 to detach from the arc-shaped groove. Then, the controller 32 controls the stepper motor 18 to operate, and its output shaft drives the rotating plate 11 to rotate through the drive rod 15, switching the next set of test tubes to be heated to the top of the arc-shaped groove. The electric push rod 24 drives the rotating plate 11 to fall again, repeating the heating and analysis process to achieve continuous processing of multiple sets of samples.
