Description

Technical Field

[0001] The utility model relates to the technical field of stirring equipment, in particular to a rotary temperature measuring power mixer. Background Art

[0002] The power mixer is a mixing equipment that combines low-speed mixing and high-speed mixing. It is equipped with a coaxially arranged high-speed shaft and a low-speed shaft. Its working principle is: the planetary frame is fixed on the low-speed shaft by locking the upper and lower nuts, the scraper assembly is installed on the planetary frame and rotates at a low speed with the planetary frame, and the high-speed shaft drives the dispersion shaft to rotate at a high speed through gears.

[0003] During the operation of the power mixer, it is necessary to measure the temperature of the material in the material cylinder. In order to ensure accurate temperature measurement, it is necessary to perform rotational temperature measurement at multiple points in the mixing chamber. For this purpose, the temperature measuring probe will be installed on the scraping assembly, and the temperature measuring probe will rotate with the scraping assembly at a low speed to achieve rotational temperature measurement. The temperature measuring line of the temperature measuring probe must be led out at the top of the equipment, so the low-speed rotating temperature measuring line needs to pass through the high-speed shaft, but the low-speed rotating temperature measuring line and the high-speed shaft have different rotation speeds, which will make it difficult to lead the temperature measuring line of the temperature measuring probe to the outside of the equipment. Utility Model Content

[0004] In order to overcome the defects of the prior art, the utility model provides a rotary temperature measuring power mixer to solve the above problems.

[0005] The technical solution adopted by the utility model to solve the technical problem is: a rotary temperature measuring power mixer, comprising a low-speed stirring module, a high-speed mixing module, a temperature measuring probe, a temperature measuring line, a conductive slip ring and a mixing chamber;

[0008] The scraping edge assembly and the dispersion shaft are both arranged in the mixing chamber;

[0009] The high-speed rotating shaft is arranged in the low-speed rotating shaft, and the lower end of the high-speed rotating shaft is connected to the lower end of the low-speed rotating shaft through a lower bearing, and the upper end of the high-speed rotating shaft is connected to the upper end of the low-speed rotating shaft through an upper bearing, and the conductive slip ring is connected to the upper bearing so that the conductive slip ring and the low-speed rotating shaft rotate synchronously, one end of the temperature measuring wire is electrically connected to the temperature measuring probe, and the other end of the temperature measuring wire is electrically connected to the conductive slip ring after passing through the high-speed rotating shaft, and the temperature measuring wire will not contact the wall surface of the high-speed rotating shaft.

[0010] Preferably, it further comprises a frame, and the low-speed rotating shaft is arranged on the frame and is rotationally connected to the frame.

[0011] Optionally, the low-speed stirring module further comprises a planetary frame, in which a planetary gear set is arranged, and the scraping assembly and the dispersion shaft are both drivingly connected to the low-speed rotating shaft via the planetary gear set.

[0012] Specifically, the dispersion shaft is rotationally connected to a corresponding gear in the planetary gear set;

[0013] The high-speed hybrid module further comprises an output driving wheel and an output driven wheel, wherein the output driving wheel is arranged on the high-speed rotating shaft, the output driven wheel is arranged on the dispersion shaft, and the output driving wheel is meshingly connected with the output driven wheel.

[0014] It is worth noting that the low-speed stirring module also includes a low-speed motor, a first input driving wheel and a first input driven wheel. The output shaft of the low-speed motor is provided with the first input driving wheel, and the low-speed rotating shaft is provided with the first input driven wheel.

[0016] The beneficial effect of the utility model is that in the power mixer with rotary temperature measurement, by setting the upper bearing and the lower bearing, the high-speed shaft and the low-speed shaft can rotate relative to each other at different speeds. At this time, the temperature measuring probe rotates with the scraping assembly, and the scraping assembly rotates with the low-speed shaft. It can be seen that the temperature measuring probe rotates with the low-speed shaft, and the temperature measuring line also rotates with the low-speed shaft, thereby realizing rotary temperature measurement. Since the temperature measuring line does not contact the wall of the high-speed shaft, the rotation of the high-speed shaft will not affect the rotation of the temperature measuring line. In addition, since the conductive slip ring rotates synchronously with the low-speed shaft, after the temperature measuring line passes through the high-speed shaft and is electrically connected to the conductive slip ring, it can continue to rotate synchronously with the low-speed shaft, thereby achieving the purpose of leading the temperature measuring line of the temperature measuring probe to the outside of the equipment, thereby realizing the temperature measurement function of the power mixer.

DETAILED DESCRIPTION

[0021] The specific implementation methods of the present invention are further described below in conjunction with the accompanying drawings. It should be noted that the description of these implementation methods is used to help understand the present invention, but does not constitute a limitation of the present invention. In addition, the technical features involved in each implementation method of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0022] like Figure 1-3 As shown, a rotary temperature measuring power mixer comprises a low-speed stirring module 1, a high-speed mixing module 2, a temperature measuring probe 5, a temperature measuring line 6, a conductive slip ring 7 and a mixing chamber 8;

[0023] The low-speed stirring module 1 comprises a low-speed rotating shaft 11 and a scraping assembly 12, the low-speed rotating shaft 11 is in transmission connection with the scraping assembly 12, and the temperature measuring probe 5 is arranged on the scraping assembly 12;

[0024] The high-speed mixing module 2 includes a high-speed rotating shaft 21 and a dispersion shaft 22, and the high-speed rotating shaft 21 is transmission-connected with the dispersion shaft 22;

[0025] The scraping assembly 12 and the dispersion shaft 22 are both disposed in the mixing chamber 8;

[0026] The high-speed rotating shaft 21 is arranged in the low-speed rotating shaft 11, and the lower end of the high-speed rotating shaft 21 is connected to the lower end of the low-speed rotating shaft 11 through a lower bearing 3, and the upper end of the high-speed rotating shaft 21 is connected to the upper end of the low-speed rotating shaft 11 through an upper bearing 4. The conductive slip ring 7 is connected to the upper bearing 4 so that the conductive slip ring 7 and the low-speed rotating shaft 11 rotate synchronously. One end of the temperature measuring wire 6 is electrically connected to the temperature measuring probe 5, and the other end of the temperature measuring wire 6 is electrically connected to the conductive slip ring 7 after passing through the high-speed rotating shaft 21, and the temperature measuring wire 6 will not contact the wall surface of the high-speed rotating shaft 21.

[0027] In the rotary temperature measurement power mixer, by setting the upper bearing 4 and the lower bearing 3, the high-speed shaft 21 and the low-speed shaft 11 can rotate relative to each other at different speeds. At this time, the temperature measuring probe 5 rotates following the scraping assembly 12, and the scraping assembly 12 rotates following the low-speed shaft 11. It can be seen that the temperature measuring probe 5 rotates following the low-speed shaft 11, and the temperature measuring line 6 also rotates following the low-speed shaft 11, thereby realizing rotary temperature measurement. Since the temperature measuring line 6 does not contact the wall surface of the high-speed shaft 21, the rotation of the high-speed shaft 21 will not affect the rotation of the temperature measuring line 6. In addition, since the conductive slip ring 7 rotates synchronously with the low-speed shaft 11, after the temperature measuring line 6 passes through the high-speed shaft 21 and is electrically connected to the conductive slip ring 7, it can continue to rotate synchronously with the low-speed shaft 11, achieving the purpose of leading the temperature measuring line 6 of the temperature measuring probe 5 to the outside of the device, thereby realizing the temperature measurement function of the power mixer.

[0028] In this embodiment, the purpose of describing high speed and low speed is to distinguish the different rotation speeds between the high-speed shaft 21 and the low-speed shaft 11. In comparison, the rotation speed of the high-speed shaft 21 is higher than that of the low-speed shaft 11, and the rotation speed of the low-speed shaft 11 is lower than that of the high-speed shaft 21.

[0029] It is worth noting that the machine frame 9 is also included, and the low-speed shaft 11 is disposed on the frame 9 and is rotatably connected to the frame 9. In this way, the low-speed shaft 11 can rotate relative to the frame 9, and since the high-speed shaft 21 is connected to the low-speed shaft 11 through a bearing, the high-speed shaft 21 can also rotate relative to the frame 9.

[0030] Optionally, the low-speed stirring module 1 further includes a planetary frame 13, in which a planetary gear set is provided, and the scraping assembly 12 and the dispersion shaft 22 are both connected to the low-speed rotating shaft 11 through the planetary gear set. The planetary frame 13 and the planetary gear set are existing structures, and by connecting the low-speed rotating shaft 11 to the middle gear in the planetary gear set, and connecting the scraping assembly 12 and the dispersion shaft 22 to the peripheral gears outside the middle gear in the planetary gear set, when the low-speed rotating shaft 11 rotates, the scraping assembly 12 and the dispersion shaft 22 can be driven to rotate around the low-speed rotating shaft 11. The purpose of stirring the dispersion shaft 22 in the mixing chamber 8 is achieved, and the purpose of the scraping assembly 12 scraping the inner wall of the mixing chamber 8 is achieved.

[0031] Preferably, the dispersion shaft 22 is rotationally connected with the corresponding gear in the planetary gear set; the high-speed mixing module 2 also includes an output driving wheel 23 and an output driven wheel 24, the output driving wheel 23 is arranged on the high-speed rotating shaft 21, the output driven wheel 24 is arranged on the dispersion shaft 22, and the output driving wheel 23 is meshed and connected with the output driven wheel 24. The high-speed rotating shaft 21 and the low-speed rotating shaft 11 are coaxially arranged, when the dispersion shaft 22 rotates around the low-speed rotating shaft 11, the distance between the dispersion shaft 22 and the high-speed rotating shaft 21 remains unchanged, so that the high-speed rotating shaft 21 can drive the dispersion shaft 22 to rotate through the output driving wheel 23 and the output driven wheel 24, so as to achieve the purpose of material mixing.

[0032] Specifically, the low-speed stirring module 1 further includes a low-speed motor 14, a first input driving wheel 15 and a first input driven wheel 16. The output shaft of the low-speed motor 14 is provided with the first input driving wheel 15, and the low-speed rotating shaft 11 is provided with the first input driven wheel 16. The first input driving wheel 15 is transmission-connected with the first input driving wheel 15. The low-speed motor 14 can drive the low-speed rotating shaft 11 to rotate through the first input driving wheel 15 and the first input driven wheel 16.

[0033] It is worth noting that the high-speed hybrid module 2 further includes a high-speed motor 25, a second input driving wheel 26, and a second input driven wheel 27. The output shaft of the high-speed motor 25 is provided with a second input driving wheel 26, and the high-speed rotating shaft 21 is provided with a second input driven wheel 27. The second input driving wheel 26 is transmission-connected with the second input driving wheel 26.
