[0031] Please see Figures 1 to 4 To better understand the multi-temperature probe stirred tank 10 of this application, the following further explanation of the multi-temperature probe stirred tank 10 is provided:

[0032] The multi-temperature probe stirring kettle 10 of one embodiment comprises a kettle body 100, a stirring assembly 200 and a temperature sensing assembly 300. The kettle body 100 comprises a kettle cover 110 and a kettle body 120; the kettle cover 110 is arranged on the kettle body 120, and the kettle cover 110 and the kettle body 120 jointly form a stirring chamber 101 for containing slurry; the stirring assembly 200 comprises a stirring driving member 210 and a stirrer 220; the stirring driving member 210 is located above the kettle cover 110, one end of the stirrer 220 penetrates through the kettle cover 110 and is connected with the power output end of the stirring driving member 210, and the other end of the stirrer 220 is used for stirring the slurry; the temperature sensing assembly 300 comprises a plurality of temperature probes 310, the plurality of temperature probes 310 are distributed around the rotation center axis of the stirrer 220, the monitoring ends of the plurality of temperature probes 310 all penetrate through the kettle cover 110 and extend into the stirring chamber 101, and the conductive ends of the plurality of temperature probes 310 are all electrically connected with the control end of the stirring driving member 210.

[0033] In the embodiment, since the plurality of temperature probes 310 are distributed around the rotation center axis of the stirrer 220, and the monitoring ends of the plurality of temperature probes 310 all penetrate through the kettle cover 110 and extend into the stirring chamber 101, the monitoring ends of the plurality of temperature probes 310 can monitor the temperature of the slurry being heated and stirred in the stirring chamber 101 in all directions in real time, so that the stirring driving member 210 can output a corresponding stirring speed according to the monitored temperature of the slurry, so as to effectively drive the stirrer 220 to stir the slurry in different gelatinization stages, so that the mixing uniformity and viscosity of the slurry are better.

[0034] As shown in FIGS. 1 to 3, in one embodiment, the conductive end of each temperature probe 310 protrudes from the kettle cover 110, and the monitoring end of each temperature probe 310 penetrates through the kettle cover 110. Figure 1 Figure 3 As shown in FIGS. 1 to 3, in one embodiment, the conductive end of each temperature probe 310 protrudes from the kettle cover 110, and the monitoring end of each temperature probe 310 penetrates through the kettle cover 110.

[0035] ​It can be understood that in the present embodiment, the number of temperature probes 310 is four, i.e. four temperature probes 310 are arranged around the rotation center axis of the stirrer 220, ensuring that the plurality of temperature probes 310 can monitor the temperature of the slurry in all directions in real time; Specifically, for example, when the plurality of temperature probes 310 monitor that the local temperature difference of the slurry is too large, the temperature probe 310 can transmit an electrical signal to the stirring driving member 210, so that the stirring driving member 210 increases the stirring speed, thereby improving the uniformity of the slurry heating. For another example, the plurality of temperature probes 310 can make the stirring driving member 210 output the corresponding stirring speed according to the temperature change of the slurry at different gelatinization stages; in the early stage of slurry gelatinization, the plurality of temperature probes 310 monitor that the slurry temperature is low, and the stirring driving member 210 outputs a high stirring speed to ensure the uniformity of the slurry mixing; in the later stage of slurry gelatinization, the plurality of temperature probes 310 monitor that the slurry temperature reaches the preset temperature, and the stirring driving member 210 outputs a low stirring speed to ensure the viscosity of the slurry.

[0036] As shown in Figures 2 to 4 In one embodiment, the multi-temperature probe stirring kettle 10 further comprises a heating assembly 400, the heating assembly 400 comprises a hot gas delivery pipe 410 and a hose 420; one end of the hot gas delivery pipe 410 penetrates through the kettle cover 110 and extends into the stirring chamber 101, the other end of the hot gas delivery pipe 410 protrudes from the kettle cover 110, and the other end of the hot gas delivery pipe 410 is connected to a hot gas supply system through the hose 420.

[0037] It can be understood that in the present embodiment, the hot gas supply system (not shown) supplies water vapor for heating the slurry to the hot gas delivery pipe 410 through the hose 420, i.e. uses water vapor with heat to heat the slurry, so that the uniformity of the slurry heating is good, thereby avoiding the problem of local overheating of the slurry leading to burning paste; at the same time, in combination with the corresponding stirring speed output by the stirring driving member 210, the stirring speed of the stirring driving member 210 is effectively driven to stir the slurry at different gelatinization stages, thereby effectively ensuring the mixing uniformity and viscosity of the slurry.

[0038] As shown in Figure 1 and Figure 4 In one embodiment, the heating assembly 400 further comprises a fixing block 430, the fixing block 430 is provided with a positioning through hole 4301, and the fixing block 430 is welded to the inner wall of the stirring chamber 101, and the other end of the hot gas delivery pipe 410 penetrates through the positioning through hole 4301.

[0039] It can be understood that the positioning through hole 4301 can better limit the shaking of the other end of the hot gas delivery pipe 410, thereby improving the installation stability of the other end of the hot gas delivery pipe 410.

[0040] As Figure 1 shown, in one embodiment, the kettle cover 110 is provided with a first member 1110 and a second member 1120; the first member 1110 and the second member 1120 are arranged in a spaced manner, so that a spacing gap 1102 is formed between the first member 1110 and the second member 1120. In one embodiment, the stirring drive 210 includes a stirring motor 2110 and a reducer 2120; the reducer 2120 is fixedly arranged above the first member 1110 and above the second member 1120, the output shaft of the stirring motor 2110 is connected with the input shaft of the reducer 2120, and one end of the stirrer 220 penetrates the kettle cover 110 and the spacing gap 1102 in sequence and is connected with the output shaft of the reducer 2120.

[0041] It can be understood that the first member 1110 and the second member 1120 provide an installation platform with good structural strength for the reducer 2120, so as to ensure that the stirring motor 2110 can output larger torque to the stirrer 220 through the reducer 2120, so that the stirrer 220 can output reliable stirring speed.

[0042] Specifically, in the embodiment, the other end of the stirrer 220 is fixedly installed with a stirring blade for stirring the slurry, wherein the other end of the hot gas delivery pipe 410 is located at the periphery of the stirring area of the stirring blade, so that the other end of the hot gas delivery pipe 410 cannot interfere with the rotation and stirring of the stirring blade, and the structural rationality of the multi-temperature probe stirring kettle 10 is ensured.

[0043] As Figure 1 shown, in one embodiment, the first member 1110 and the second member 1120 are both channel steels. In this way, the first member 1110 and the second member 1120 have good weighing performance, so as to ensure the reliability of the installation of the stirring motor 2110 and the reducer 2120. Of course, this is not limited here, and those skilled in the art can also make other selections according to needs. For example, in other embodiments, the first member 1110 and the second member 1120 are both square tubes, I-beams and H-shaped steels.

[0044] As Figure 1 shown, in one embodiment, the reducer 2120 is a right-angle reducer 2120. In this way, the installation structure of the stirring motor 2110 and the reducer 2120 is more flexible, and the overall structure of the multi-temperature probe stirring kettle 10 is better in compactness.

[0045] As Figure 1As shown in one of the embodiments, the kettle cover 110 is provided with a feeding opening 1101 communicated with the stirring chamber 101, and a rotating cover plate (not shown) is arranged on the kettle cover 110 and covers the feeding opening 1101. In this way, the heating effect of the slurry in the stirring chamber 101 is effectively ensured, and the excessive loss of heat is avoided.

[0046] As shown in one of the embodiments, the kettle cover 110 is provided with a feeding opening 1101 communicated with the stirring chamber 101, and a rotating cover plate (not shown) is arranged on the kettle cover 110 and covers the feeding opening 1101. In this way, the heating effect of the slurry in the stirring chamber 101 is effectively ensured, and the excessive loss of heat is avoided. Figure 1 Figure 3 As shown in one of the embodiments, the kettle cover 110 is provided with a pressure reducing pipe 1130, one end of which is communicated with the stirring chamber 101, and the other end of which is communicated with the external space.

[0047] It can be understood that during the gelatinization of the slurry, the gas in the stirring chamber 101 will be heat-expanded, so that the pressure difference between the stirring chamber 101 and the external space is generated. In this way, the excessive heat-expanded gas can be guided out of the external space through the pressure reducing pipe 1130, so as to maintain the pressure balance between the stirring chamber 101 and the external space.

[0048] It should be noted that the multi-temperature probe stirring kettle 10 of the present disclosure only protects the electrical connection relationship between the temperature probe 310 and the stirring motor 2110, and the control method of adjusting the output stirring rate of the stirring motor 2110 according to the monitoring temperature of the temperature probe 310 belongs to the prior art and is not within the protection scope of the present disclosure.

[0049] Compared with the prior art, the present utility model has at least the following advantages:

[0050] Since the multiple temperature probes are distributed around the rotation center axis of the stirrer, and the monitoring ends of the multiple temperature probes are all penetrated through the kettle cover and extended into the stirring chamber, the monitoring ends of the multiple temperature probes can monitor the temperature of the slurry being heated and stirred in the stirring chamber in all directions in real time. Therefore, the stirring driving member can output the corresponding stirring rate according to the monitored slurry temperature, so as to effectively drive the stirrer to stir the slurry in different gelatinization stages. In this way, the mixing uniformity and viscosity of the slurry are good.

[0051] The above-described embodiments only express several implementation manners of the present utility model, and the description is relatively specific and detailed, but it should not be understood as a limitation on the scope of the utility model patent. It should be noted that, for ordinary skilled persons in the art, without departing from the concept of the present utility model, a number of modifications and improvements can be made, which all belong to the protection scope of the present utility model. Therefore, the protection scope of the utility model patent should be subject to the appended claims.​
