Description

Technical Field

[0001] This utility model relates to a heating device, particularly a heating device for chemical analysis, and belongs to the field of chemical machinery design and manufacturing technology. Background Technology

[0002] Chemical analysis is a crucial method for determining the chemical composition or structure of substances. Raw materials, semi-finished products, and finished products in industry; agricultural products, soil, fertilizers, and feed in agriculture; and fuels and lubricants in transportation all require chemical analysis to clarify their composition or structure during research, trial production, manufacturing, or use. This process often involves heating and dissolving the chemical substances. Existing technologies mostly use heating devices to achieve this. Utility model patent CN213160330U discloses a heating device for chemical analysis, but it can only heat the chemical substances in one set of beakers at a time, and the heating relies on a heating element at the bottom of the beakers. This limits the contact area between the heat source and the chemical substances in the beakers, resulting in slow heating rates, long heating times, and significant heat loss. Furthermore, after the chemical substances in the beakers are heated, the beakers are at a high temperature, making it easy for operators to get burned or slip and lose the heated chemical substances when handling them. Therefore, it is necessary to improve the existing technology. Summary of the Invention

[0003] To address the problems of uneven heating, low heating rate, and inconvenience in handling beakers after heating in existing chemical analysis heating devices, this utility model provides a chemical analysis heating device.

[0004] This utility model is achieved through the following technical solution: a heating device for chemical analysis, comprising a base, characterized in that it further comprises a beaker clamping mechanism, a gantry-shaped support, a stirring and heating assembly, a rotating mechanism, and a lifting mechanism; wherein:

[0005] The base is provided with a heating pad for heating a beaker and a slot located outside the heating pad. The beaker clamping mechanism is movably inserted into the slot. Above the beaker clamping mechanism is a stirring and heating assembly for stirring and heating the contents of the beaker. The stirring and heating assembly is connected to a rotating mechanism for driving the stirring and heating assembly. The rotating mechanism is connected to a lifting mechanism located on the portal frame for driving the stirring and heating assembly to insert or detach from the beaker. The portal frame is located on the base and above the beaker clamping mechanism, the stirring and heating assembly, and the rotating mechanism, so that the contents of the beaker can be heated as a whole through the cooperation of the heating pad and the stirring and heating assembly. This improves the heating rate and ensures the uniformity of heating, providing convenience for chemical analysis experiments. It also allows the beaker clamping mechanism to move back and forth in the slot of the base, making it convenient for operators to move the heated beaker and avoiding accidents such as burns or slips caused by directly handling the hot beaker.

[0006] Furthermore, the heating pad is disc-shaped and embedded in a circular groove on the top of the base so as to heat the bottom of the beaker by means of an electric heating pad.

[0007] Furthermore, multiple beaker clamping mechanisms are provided on the base, and multiple corresponding stirring and heating components and rotating mechanisms are also provided, so as to dissolve and analyze various chemical substances separately and improve work efficiency.

[0008] Furthermore, the beaker clamping mechanism includes two symmetrically arranged upper rectangular sleeves and lower trapezoidal plates of gradually decreasing size, each sleeved within its corresponding upper rectangular sleeve. A clamping assembly is provided between the two upper rectangular sleeves, and a moving assembly is provided at the bottom of each lower trapezoidal plate; wherein:

[0009] The clamping assembly includes a horizontal screw rod disposed between two upper rectangular sleeve plates. The threads on both sides of the horizontal screw rod are opposite to each other and are screwed to the left and right vertical clamping plates on the corresponding threaded sections on both sides of the horizontal screw rod. The screw rod is used to drive the left and right vertical clamping plates to move inward simultaneously to clamp the beaker, or to move outward simultaneously to release the clamping of the beaker.

[0010] The two ends of the horizontal screw are respectively rotatably connected to the bearings in the corresponding upper rectangular sleeves, and one end of the horizontal screw extends outward through the bearing in the upper rectangular sleeve and is connected to the handwheel on the outside; a horizontal slide bar is also provided between the tops of the two upper rectangular sleeves, and the horizontal slide bar is slidably engaged with the tops of the left and right vertical clamping plates.

[0011] The moving component includes multiple ball bowls located at the bottom of the lower trapezoidal plate, and a rolling ball movably fitted inside each ball bowl;

[0012] The beaker is clamped by rotating the handwheel so that the horizontal screw can move the left and right vertical clamps inward simultaneously. Conversely, the clamping of the beaker is released by rotating the handwheel. The beaker clamping mechanism and the clamped beaker can be easily moved by the ball bowl and the rolling ball inside the lower trapezoidal plate, avoiding burns or slips caused by directly handling the hot beaker.

[0013] Furthermore, the outer side of the upper rectangular sleeve is provided with an anti-slip pad, and the inner sides of the left and right vertical clamping plates are provided with anti-slip blocks, so that the anti-slip pad can prevent slipping when picking up the beaker clamping mechanism, and the anti-slip blocks can prevent the beaker from falling off when clamping the beaker.

[0014] Furthermore, the slot is configured as a strip-shaped groove that mates with the lower trapezoidal plate. The strip-shaped groove is located on both sides of the heating pad so that the beaker clamping mechanism can be inserted into the strip-shaped groove and fixed by the strip-shaped groove, thereby allowing the beaker clamping mechanism to be stably placed on the heating pad for easy clamping of the heated beaker.

[0015] Furthermore, the stirring and heating assembly includes a vertical stirring rod disposed above the beaker clamping mechanism, and several horizontal blades disposed on the vertical stirring rod. An electric heating tube is movably sleeved inside the vertical stirring rod, and the upper end of the electric heating tube is electrically connected to an external power source through a wire, so that the liquid in the beaker can be rotated and stirred by the vertical stirring rod. The vertical stirring rod is heated first by the electric heating tube, which does not rotate with the vertical stirring rod, and then the liquid and chemical substances in the beaker are heated by the vertical stirring rod.

[0016] Furthermore, the rotating mechanism includes a housing with an internal cavity. A drive gear is horizontally arranged inside the housing cavity, and multiple driven gears mesh with the drive gear. A power unit is located at the top of the housing. The main shaft of the power unit passes downward through the housing and is connected to the drive gear. The driven gears are connected to the upper end of the vertical stirring rod that passes through the housing and is located in the cavity. The upper end of the electric heating tube is fixed to the top of the housing by a washer, and the lower end extends downward through a through hole at the top of the housing and is inserted into the vertical stirring rod. This allows the power unit to sequentially drive the drive gear and the driven gears to rotate the vertical stirring rod and complete the stirring. At the same time, the electric heating tube, which does not rotate with the vertical stirring rod, first heats the vertical stirring rod, and then the vertical stirring rod heats the liquid and chemical substances in the beaker.

[0017] Furthermore, the bottom of the shell is provided with a sealing cap that mates with the beaker. The bottom of the sealing cap is provided with an annular slot that mates with the edge of the beaker's opening, which is used to seal the opening at the top of the beaker, so as to improve the heating efficiency of the beaker and also to keep it warm.

[0018] Furthermore, the lifting mechanism includes a power cylinder located on one side of the top crossbeam of the portal frame. The lower end of the piston rod of the power cylinder extends downward through the corresponding original through hole on the crossbeam and connects to one side of the top of the housing. The other side of the top of the housing is connected to the lower end of a guide rod. The upper end of the guide rod slides through the through hole on the other side of the top crossbeam of the portal frame and extends upward to connect to a stop with a size larger than the through hole. This allows the power cylinder to drive the rotating mechanism and the stirring and heating assembly to rise as a whole and leave the beaker, or to descend as a whole so that the stirring and heating assembly can be inserted into the beaker to complete the heating, stirring, and dissolving of the liquid or chemical substance inside.

[0019] This utility model has the following advantages and effects:

[0020] (1) When performing chemical analysis, the operator can place the beaker on the heating pad and heat the chemical substances inside the beaker from the bottom. At the same time, the inside of the beaker can be heated and stirred by inserting a stirring rod into the beaker. This heating method greatly improves the heating and dissolution efficiency.

[0021] (2) After the chemical substances inside the beaker have been heated and dissolved, the beaker can be fixed on the beaker clamping mechanism by the clamping component. When the beaker needs to be moved, the beaker clamping mechanism can be moved easily by the rolling ball, which effectively reduces the workload of the operator and improves work efficiency.

Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model. Example

[0028] The heating device for chemical analysis provided by this utility model includes a base 1, a beaker clamping mechanism 2, a gantry-shaped support 3, a stirring and heating assembly 4, a rotating mechanism 6, and a lifting mechanism 8; wherein:

[0029] The base 1 is provided with a heating pad 13 for heating the bottom of the beaker and a slot 14 located outside the heating pad 13. The beaker clamping mechanism 2 is movably inserted into the slot 14. Above the beaker clamping mechanism 2 is a stirring and heating assembly 4 for stirring and heating the contents of the beaker. The stirring and heating assembly 4 is connected to the rotating mechanism 6 for driving the stirring and heating assembly 4. The rotating mechanism 6 is connected to the lifting mechanism 8 provided on the portal bracket 3 for driving the stirring and heating assembly 4 to insert or detach from the beaker. The portal bracket 3 is provided on the base 1 and is located above the beaker clamping mechanism 2, the stirring and heating assembly 4, and the rotating mechanism 6, so that the contents of the beaker can be heated as a whole through the cooperation of the heating pad 13 and the stirring and heating assembly 4. While improving the heating rate, it can also ensure the uniformity of heating, providing convenience for chemical analysis experiments. It can also allow the beaker clamping mechanism 2 to move back and forth in the slot 14 of the base 1, making it convenient for operators to move the heated beaker and avoid accidents such as burns or slips caused by directly picking up the hot beaker.

[0030] As an example, the heating pad 13 is a commercially available disc-shaped electric heating pad, and is embedded in the circular groove 17 at the top of the base 1 so as to heat the bottom of the beaker through the heating pad 13.

[0031] In this embodiment, the beaker clamping mechanism 2 is provided on the base 1 in two sets, left and right. Correspondingly, the stirring and heating assembly 4 and the rotating mechanism 6 are also provided in two sets, left and right, so as to dissolve and analyze various chemical substances separately and improve work efficiency.

[0032] As one embodiment, the beaker clamping mechanism 2 includes two symmetrically arranged upper rectangular sleeves 19 and lower trapezoidal plates 16 with gradually decreasing dimensions, each sleeved in its corresponding upper rectangular sleeve 19. A clamping assembly is provided between the two upper rectangular sleeves 19, and a moving assembly is provided at the bottom of each lower trapezoidal plate 16; wherein:

[0033] The clamping assembly includes a horizontal screw 21 disposed between two upper rectangular sleeve plates 19. The threads on both sides of the horizontal screw 21 are opposite to each other. The left and right vertical clamping plates 20 are screwed to the corresponding threaded sections on both sides of the horizontal screw 21. The screw 21 is used to drive the left and right vertical clamping plates 20 to move inward simultaneously to clamp the beaker, or to move outward simultaneously to release the clamping of the beaker.

[0034] The two ends of the horizontal screw 21 are respectively rotatably connected to the bearings in the corresponding upper rectangular sleeve 19, and one end of the horizontal screw 21 extends outward through the bearing in the upper rectangular sleeve 19 and is connected to the handwheel 24 on the outside; a horizontal slide bar 22 is also provided between the tops of the two upper rectangular sleeves 19, and the horizontal slide bar 22 is slidably engaged with the tops of the left and right vertical clamping plates 20;

[0035] The moving component includes a plurality of ball bowls disposed at the bottom of the lower trapezoidal plate 16, and a rolling ball 15 movably fitted inside each ball bowl;

[0036] The beaker is clamped by rotating the handwheel 24 so that the horizontal screw 21 can move the left and right vertical clamping plates 20 inward at the same time. Conversely, the clamping of the beaker is released by rotating the handwheel 24. The beaker clamping mechanism 2 and the clamped beaker can be moved easily by the ball bowl at the bottom of the lower trapezoidal plate 16 and the rolling ball 15 inside it, avoiding the risk of burns or slips caused by directly handling the hot beaker.

[0037] As an example, the upper rectangular sleeve plate 19 is provided with an anti-slip pad 18 on its outer side, and the left and right vertical clamping plates 20 are provided with anti-slip blocks 23 on their opposite inner sides, so that the anti-slip pad 18 can prevent slipping when picking up the beaker clamping mechanism 2, and the anti-slip blocks 23 can prevent the beaker from falling off when clamping the beaker.

[0038] As an example, the slot 14 is configured as a strip-shaped groove that mates with the lower trapezoidal plate 16. The strip-shaped groove is located on the left and right sides of the heating pad 13 so that the beaker clamping mechanism 2 can be inserted into the strip-shaped groove and fixed by the strip-shaped groove, so that the beaker clamping mechanism 2 can be stably placed on the heating pad 13 to facilitate clamping the heated beaker.

[0039] As one embodiment, the stirring and heating assembly 4 includes a vertical stirring rod 26 disposed above the beaker clamping mechanism 2, and a plurality of horizontal blades 25 disposed on the vertical stirring rod 26. An electric heating tube 28 is movably sleeved inside the vertical stirring rod 26. The upper end of the electric heating tube 28 is electrically connected to an external power source through a wire so that the liquid in the beaker can be rotated and stirred by the vertical stirring rod 26. The vertical stirring rod 26 is heated first by the electric heating tube 28, which does not rotate with the vertical stirring rod 26, and then the liquid and chemical substances in the beaker are heated by the vertical stirring rod 26.

[0040] As one embodiment, the rotating mechanism 6 includes a housing 5 with an internal cavity. A drive gear 11 is horizontally arranged inside the cavity of the housing 5, and two driven gears 12 meshing with the drive gear 11 are also provided. A power unit 7 is provided at the top of the housing 5. The main shaft of the power unit 7 passes downward through the housing 5 and is connected to the drive gear 11. The driven gears 12 are connected to the upper end of the vertical stirring rod 26 that passes through the housing 5 and is located in the cavity. The upper end of the electric heating tube 28 is fixed to the top of the housing 5 by a washer, and the lower end extends downward through a through hole at the top of the housing 5 and is inserted into the vertical stirring rod 26. This allows the power unit 7 to sequentially drive the drive gear 12 and the driven gears 12 to rotate the vertical stirring rod 26 and complete the stirring. At the same time, the electric heating tube 28, which does not rotate with the vertical stirring rod 26, first heats the vertical stirring rod 26, and then the vertical stirring rod 26 heats the liquid and chemical substances in the beaker.

[0041] As an example, the bottom of the housing 5 is also provided with a sealing cover 27 that mates with the beaker. The bottom of the sealing cover 27 is provided with an annular slot 29 that mates with the edge of the beaker's opening, which is used to close the opening at the top of the beaker in order to improve the heating efficiency of the beaker and also to keep it warm.

[0042] As one embodiment, the lifting mechanism 8 includes a power cylinder 9 disposed on one side of the top crossbeam of the portal frame 3. The lower end of the piston rod of the power cylinder 9 extends downward through the corresponding through hole on the crossbeam and is connected to one side of the top of the housing 5. The other side of the top of the housing 5 is connected to the lower end of the guide rod 10. The upper end of the guide rod 10 slides through the through hole on the other side of the top crossbeam of the portal frame 3 and extends upward to connect with a stop larger than the through hole. This allows the power cylinder 9 to drive the rotating mechanism 6 and the stirring and heating assembly 4 to rise as a whole and leave the beaker, or to descend as a whole so that the stirring and heating assembly 4 can be inserted into the beaker to complete the heating, stirring, and dissolving of the liquid or chemical substance inside.
