[0004] With respect to the above-mentioned related technologies, the inventors found that by passing hot water into the hot water pipe to heat Tank No. 1 or passing cold water into the cold water pipe to cool Tank No. 2, the heat exchange medium needs to transfer heat through the pipe wall and the inner wall of the tank to exchange heat with the substances in the tank, and the heat exchange effect is not good.

[0008] By adopting the above technical solution, hot water or cold water enters the water inlet channel through the water inlet pipe, and then flows into the heat exchange channel in each stirring blade from the water inlet channel. In the process of stirring the material by driving the stirring shaft to rotate through the driving member, the heat exchange medium exchanges heat with the material in the heat exchange channel and the water inlet channel. Since heat is transferred between the heat exchange medium and the material only through the stirring blades, and the heat exchange time and path are extended, the heat exchange effect is improved to a certain extent, which facilitates the heating or cooling of the material; the water in the water inlet channel enters the water outlet channel through the notch on the mounting ring, and is then discharged from the return pipe.

[0009] Preferably, a first connecting ring is rotatably provided on the top wall of the tank body, and the rotation axis of the first connecting ring is parallel to the rotation axis of the stirring shaft. A second connecting ring is arranged inside the first connecting ring.

[0012] By adopting the above technical solution, hot water or cold water enters the channel formed by the first connecting ring and the second connecting ring through the water inlet pipe, and water drops fall on the impeller, driving the impeller to rotate relative to the stirring shaft. The impeller is driven to rotate through the transmission member to drive the stirring shaft to slide, thereby achieving the up and down sliding of the stirring shaft while rotating, making the heat exchange more uniform, helping to improve the heating or cooling effect, and saving costs at the same time.

[0013] Preferably, the transmission member includes a transmission ring arranged on the side of the impeller close to the stirring shaft and a transmission rod arranged on the inner wall of the stirring shaft, the transmission rod and the end surface of the transmission ring close to the stirring shaft are slidingly connected, and the end surface of the transmission ring close to the transmission rod is a slope.

[0014] By adopting the above technical solution, the impeller drives the transmission ring to rotate relative to the stirring shaft. Through the sliding cooperation between the transmission ring and the transmission rod, the transmission rod drives the stirring shaft to slide up and down, making the heat exchange more uniform and helping to improve the heating or cooling effect.

[0015] Preferably, a heat exchange cover is provided on the outer wall and the bottom wall of the tank body, and a water inlet and a water outlet are provided on the heat exchange cover.

[0016] By adopting the above technical solution, hot water or cold water enters through the water inlet and is discharged through the water outlet, and heat is conducted between the heat exchange medium and the material through the tank wall of the tank body, thereby reducing the barrier between the heat exchange medium and the material, which is beneficial to improving the heat exchange effect.

[0017] Preferably, a first spiral water guide plate is arranged between the bottom wall of the tank body and the heat exchange cover, and a first water inlet pipeline is formed between the first spiral water guide plate, the heat exchange cover and the bottom wall of the tank body; a second spiral water guide plate is arranged between the side wall of the tank body and the heat exchange cover, and a second water inlet pipeline is formed between the second spiral water guide plate, the heat exchange cover and the side wall of the tank body; the first water inlet pipeline and the second water inlet pipeline are connected, the first water inlet pipeline and the water inlet are connected, and the second water inlet pipeline and the water outlet are connected.

[0018] By adopting the above technical solution, the first spiral water guide plate and the second spiral water guide plate guide the flow of the heat exchange medium, so that the hot water or cold water flows out along the first water inlet pipe and the second water inlet pipe, and it is not easy for the heat exchange medium to mix in the heat exchange cover, which helps to improve the heating or cooling effect to a certain extent.

[0019] Preferably, a cleaning pipe is provided on the stirring blade, the cleaning pipe is connected to the heat exchange channel, the cleaning pipe is provided with a high-pressure nozzle, the cleaning pipe is provided with an electric valve for opening and closing the cleaning pipe, the stirring blade is provided with a protective cover, the protective cover is arranged outside the cleaning pipe and the high-pressure nozzle, the protective cover is provided with an opening for spraying water from the high-pressure nozzle, the protective cover is hinged with an opening and closing plate for opening and closing the opening, and the protective cover is provided with an elastic driving member for driving the opening and closing plate to rotate in a direction close to the opening to close the opening.

[0020] By adopting the above technical solution, water is introduced into the water inlet channel, and the electric valve is opened to allow the water in the heat exchange channel to be sprayed out from the high-pressure nozzle through the cleaning pipe. The water impacts the opening and closing plate, causing the opening and closing plate to open, thereby cleaning the inner wall of the tank body. The method is simple and convenient, and the first connecting ring is driven by the driving member to drive the stirring shaft to rotate, so that the cleaning effect is better.

[0021] Preferably, a rotating shaft is provided on the opening and closing plate, and the rotating shaft rotates on the protective cover. The elastic driving member includes a torsion spring for driving the opening and closing plate to rotate toward a direction close to the opening. The torsion spring is sleeved on the rotating shaft, and one end of the torsion spring is provided on the protective cover, and the other end is provided on the opening and closing plate.

[0022] By adopting the above technical solution, the torsion spring drives the opening and closing plate to rotate toward the opening, so that the opening and closing plate closes the opening, thereby making it difficult for the material to enter the protective cover when the tank is filled with material, thereby reducing the possibility of the high-pressure nozzle being blocked.

[0023] Preferably, a first sliding groove for slidingly cooperating with the stirring shaft is provided on the side of the first connecting ring close to the stirring shaft, and sealing elastic strips are provided on the inner and outer walls of the first connecting ring close to the stirring shaft. The sealing elastic strip is arranged along the circumference of the first connecting ring, and the sealing elastic strip is arranged on the stirring shaft away from the first connecting ring.

[0024] By adopting the above technical solution, the sliding connection between the first connecting ring and the stirring shaft is sealed by the sealing elastic strip, which can reduce the possibility of leakage of the heat exchange medium.

[0026] By adopting the above technical solution, when the first connecting ring drives the stirring shaft to rotate, the end surface of the connecting rod and the fixed cylinder close to the stirring shaft slide relative to each other. Since the end surface of the fixed cylinder close to the stirring shaft is an inclined surface, the connecting rod drives the stirring shaft to slide up and down, which helps to make the heat exchange more uniform and improve the heating or cooling effect.

[0027] In summary, the present application includes at least one of the following beneficial technical effects:

[0028] Hot water or cold water enters the water inlet channel through the water inlet pipe, and then flows into the heat exchange channel in each stirring blade from the water inlet channel. During the process of stirring the material by driving the stirring shaft to rotate through the driving member, the heat exchange medium exchanges heat with the material in the heat exchange channel and the water inlet channel. Since there is only the inner wall of the stirring blade blocking the heat exchange medium and the material, and the heat exchange time and path are extended, the heat exchange effect is improved to a certain extent.

[0029] Hot water or cold water enters the channel formed by the first connecting ring and the second connecting ring through the water inlet pipe. Water drops fall on the impeller, driving the impeller to rotate relative to the stirring shaft.

[0040] Reference Figure 1 and Figure 2 The first connecting ring 11 on the tank body 1 is rotatably connected to the water inlet pipe 36, the stirring shaft 2 is rotatably connected to the water inlet pipe 36 through the first connecting ring 11, the second connecting ring 12 is rotatably connected to the return pipe 37, the mounting ring 5 is rotatably connected to the return pipe 37 through the second connecting ring 12, the first connecting ring 11 is provided with a sliding assembly for driving the stirring shaft 2 to slide up and down, and the tank body 1 is provided with a driving member 10 for driving the first connecting ring 11 to drive the stirring shaft 2 to rotate.

[0041] Reference Figure 1 and Figure 2The driving member 10 includes a worm wheel 101, a worm 102 and a motor 103. The worm wheel 101 is fixedly sleeved outside the first connecting ring 11, the worm 102 is rotatably arranged on the tank body 1, the worm wheel 101 and the worm 102 are meshed, the motor 103 is fixedly installed on the tank body 1, and the output ends of the worm 102 and the motor 103 are coaxially connected. In other embodiments, the worm wheel 101 and the worm 102 can be replaced by a first gear sleeved on the first connecting ring 11 and a second gear fixedly connected to the output end of the motor 103, and the first gear and the second gear are meshed.

[0042] When it is necessary to heat or cool the material in the tank body 1, hot water or cold water enters the channel formed by the first connecting ring 11 and the second connecting ring 12 through the water inlet pipe 36, and then flows into the water inlet channel 6, and then enters the heat exchange channel 9 on each stirring blade 3 from the water inlet channel 6 in turn, and then enters the water outlet channel 7 from the notch 8 at the bottom of the mounting ring 5, and finally is discharged from the return pipe 37; by starting the motor 103, the motor 103 drives the worm 102 to rotate, and the worm 102 drives the worm wheel 101 to rotate, so that the first connecting ring 11 drives the stirring shaft 2 and the mounting ring 5 to rotate, stirring and exchanging heat with the material, increasing the heat exchange path and heat exchange area, and reducing the barrier between the heat exchange medium and the material, and at the same time, the driving component drives the stirring shaft 2 to slide up and down along the length direction of the first connecting ring 11 while rotating, and the sliding cooperation of the guide block 38 and the guide groove 39 guides the sliding of the stirring shaft 2, so that the heat exchange of the material is more uniform, and the heating or cooling effect is improved to a certain extent.

[0043] Reference Figure 2 and Figure 3In order to facilitate driving the stirring shaft 2 to slide up and down, the sliding assembly includes an impeller 13 rotatably arranged on the inner wall of the first connecting ring 11 and a transmission member 14 arranged on the impeller 13. The rotation axis of the impeller 13 is parallel to the rotation axis of the first connecting ring 11. The impeller 13 is rotatably sleeved outside the second connecting ring 12 through a bearing. The transmission member 14 is used to drive the impeller 13 to rotate and drive the stirring shaft 2 to slide. The transmission member 14 includes a transmission ring 141 fixedly connected to the side of the impeller 13 close to the stirring shaft 2 and a transmission rod 142 fixedly connected to the inner wall of the stirring shaft 2. The inner diameter of the transmission ring 141 is larger than the outer diameter of the second connecting ring 12. The transmission rod 14 2 is parallel to the length direction of the stirring shaft 2, the transmission rod 142 and the end surface of the transmission ring 141 close to the stirring shaft 2 are slidably connected, the end surface of the transmission ring 141 close to the transmission rod 142 is an inclined surface, and a spherical slider 42 is fixedly connected to the side of the transmission rod 142 close to the transmission ring 141. The end surface of the transmission ring 141 close to the transmission rod 142 is provided with an annular groove 41 that slidably cooperates with the slider 42. The annular groove 41 is provided along the circumference of the transmission ring 141, and the slider 42 slides in the annular groove 41. The diameter of the slider 42 is greater than the width of the transmission rod 142, so that the slider 42 is not easily separated from the annular groove 41.

[0044] The water entering from the water inlet pipe 36 flows into the channel between the first connecting ring 11 and the second connecting ring 12, thereby driving the impeller 13 to rotate in the first connecting ring 11. Since there is a speed difference between the rotation of the impeller 13 and the rotation of the agitator shaft 2 driven by the first connecting ring 11, the slider 42 and the annular groove 41 on the transmission rod 142 slide relative to each other. Since the end face of the annular groove 41 close to the agitator shaft 2 is an inclined surface, the transmission ring 141 drives the transmission rod 142 to slide up and down, thereby realizing the up and down sliding of the agitator shaft 2, making the heat exchange more uniform and improving the heating or cooling effect. At the same time, the gravity of the water itself drives the impeller 13 to rotate, thereby realizing the up and down sliding of the agitator shaft 2, which helps to save costs.

[0045] Reference Figure 2 A heat exchange cover 17 is fixedly provided on the outer wall and the bottom wall of the tank body 1, a first spiral water guide sheet 20 is fixed between the bottom wall of the tank body 1 and the heat exchange cover 17, a first water inlet pipeline 21 is formed between the first spiral water guide sheet 20, the heat exchange cover 17 and the bottom wall of the tank body 1, the first water inlet pipeline 21 is spirally shaped, a second spiral water guide sheet 22 is fixedly connected between the side wall of the tank body 1 and the heat exchange cover 17, a second water inlet pipeline 23 is formed between the second spiral water guide sheet 22, the heat exchange cover 17 and the side wall of the tank body 1, the second water inlet pipeline 23 is spirally arranged along the height direction of the tank body 1, the first water inlet pipeline 21 and the second water inlet pipeline 23 are connected, a water inlet 18 is opened on the first water inlet pipeline 21, the water inlet 18 is connected to the water inlet pipe 36 through the first connecting pipe 43, a water outlet 19 is opened at the top of the second water inlet pipeline 23, and the water outlet 19 is connected to the return pipe 37 through the second connecting pipe 44.

[0046] The water in the water inlet pipe 36 enters the first water inlet pipeline 21 through the water inlet 18, and the water flows through the first water inlet pipeline 21 and the second water inlet pipeline 23 and returns to the return pipe 37 from the water outlet 19. Since the water and the material are separated only by the tank wall of the tank body 1, the barrier between the heat exchange medium and the material is reduced, which helps to improve the heating or cooling effect. At the same time, the first water inlet pipeline 21 and the second water inlet pipeline 23 are spiral channels, which makes it difficult for the heat exchange medium to mix in the heat exchange cover 17, which helps to improve the heat exchange effect.

[0047] Reference Figure 3 The first connecting ring 11 and the second connecting ring 12 are fixedly bonded with a sealing elastic strip 33 on the inner and outer walls of the side close to the stirring shaft 2. The sealing elastic strip 33 is a food-grade nylon strip. The sealing elastic strip 33 is respectively arranged along the circumference of the first connecting ring 11 and the second connecting ring 12. The side of the sealing elastic strip 33 on the first connecting ring 11 away from the first connecting ring 11 is bonded to the inner and outer walls of the stirring shaft 2, and the side of the sealing elastic strip 33 on the second connecting ring 12 away from the second connecting ring 12 is bonded to the inner and outer walls of the mounting ring 5. The provision of the sealing elastic strip 33 helps to reduce the leakage of the heat exchange medium and improve the product quality.

[0048] Reference Figure 2 and Figure 4 A cleaning pipe 24 is provided on the stirring blade 3, and the length direction of the cleaning pipe 24 is perpendicular to the length direction of the stirring shaft 2. The cleaning pipe 24 is connected to the heat exchange channel 9. A high-pressure nozzle 25 is provided at one end of the cleaning pipe 24 away from the stirring blade 3. The high-pressure nozzle 25 is arranged in a direction perpendicular to the stirring shaft 2. An electric valve 26 for opening and closing the cleaning pipe 24 is provided on the cleaning pipe 24. A protective cover 27 is provided on the stirring blade 3. The protective cover 27 is arranged outside the cleaning pipe 24 and the high-pressure nozzle 25. An opening 28 for spraying water from the high-pressure nozzle 25 is opened at one end of the protective cover 27 away from the stirring blade 3, and the opening 28 corresponds to the high-pressure nozzle 25. An opening and closing plate 29 for opening and closing the opening 28 is hinged on the protective cover 27, and a rotating shaft 30 is fixedly connected to the opening and closing plate 29. The rotating shaft 30 rotates on the protective cover 27, and the rotation axis of the rotating shaft 30 is in the length direction of the stirring shaft 2. The protective cover 27 is provided with an elastic driving member for driving the rotating shaft 30 to drive the opening and closing plate 29 to rotate toward the direction close to the opening 28 to close the opening 28. The elastic driving member includes a torsion spring 31 for driving the opening and closing plate 29 to rotate toward the direction close to the opening 28. The torsion spring 31 is sleeved on the rotating shaft 30, one end of the torsion spring 31 is fixedly connected to the protective cover 27, and the other end is fixedly connected to the opening and closing plate 29.

[0049] When it is necessary to clean the inner wall of the tank body 1, water is introduced into the water inlet pipe 36, and the water enters the heat exchange channel 9 through the water inlet channel 6. At this time, the electric valve 26 is controlled to open, so that water passes through the cleaning pipe 24 and is sprayed from the high-pressure nozzle 25. The high-pressure nozzle 25 sprays toward the opening and closing plate 29 to rotate the opening and closing plate 29 in a direction away from the opening 28, thereby opening the opening 28, so that water is sprayed onto the inner wall of the tank body 1, and the stirring shaft 2 is driven to rotate by starting the motor 103. The impeller 13 drives the stirring shaft 2 to slide up and down through the transmission member 14, and then the tank body 1 is cleaned, which is simple and convenient. When the tank body 1 is filled with materials, there is no impact force of the high-pressure nozzle 25 spraying water, and the torsion spring 31 drives the opening and closing plate 29 to close the opening 28, so that the materials in the tank body 1 are not easy to enter the protective cover 27, reducing the possibility of the high-pressure nozzle 25 being blocked.

[0050] The implementation principle of Example 1 of the present application is as follows: when it is necessary to heat or cool the material in the tank body 1, the heat exchange medium enters the channel formed by the first connecting ring 11 and the second connecting ring 12 through the water inlet pipe 36, and drives the impeller 13 to rotate. The heat exchange medium enters the water inlet channel 6 from the channel formed by the first connecting ring 11 and the second connecting ring 12, and then enters the heat exchange channel 9 on the stirring blade 3 from the water inlet channel 6 in sequence, and then enters the water outlet channel 7 from the notch 8 at the bottom of the mounting ring 5, and finally is discharged from the return pipe 37. At the same time, the heat exchange medium enters the first water inlet pipeline 21 through the first connecting pipe 43 and the water inlet 18, and then flows from the first water inlet pipeline 21 into the second water inlet pipeline 23, and finally flows from the water outlet 19 and the second connecting pipe 37. The pipe 44 returns to the return pipe 37, thereby increasing the heat exchange path and heat exchange area, and reducing the barrier between the heat exchange medium and the material; at this time, the motor 103 is started, and the motor 103 drives the worm 102 to rotate, and the worm 102 drives the worm wheel 101 and the first connecting ring 11 to rotate in the opposite direction of the impeller 13, and the first connecting ring 11 drives the stirring shaft 2 and the mounting ring 5 to rotate, so as to stir and exchange heat with the material. At this time, there is a speed difference between the impeller 13 and the stirring shaft 2, so that the slider 42 on the transmission rod 142 slides relatively in the annular groove 41, and then the transmission rod 142 drives the stirring shaft 2 to slide up and down in a small range, so that the heat exchange of the material is more uniform, and the heating or cooling effect is improved to a certain extent.

[0051] When it is necessary to clean the inner wall of the tank body 1, water flows into the water inlet channel 6 through the water inlet pipe 36, and then flows into the heat exchange channel 9 from the water inlet channel 6. At this time, the electric valve 26 is started to open the cleaning pipe 24, so that water flows from the high-pressure nozzle 25 to the opening and closing plate 29, and pushes the opening and closing plate 29 to rotate in a direction away from the opening 28 to open the opening 28. The motor 103 is started to drive the stirring shaft 2 to rotate, and the impeller 13 drives the stirring shaft 2 to rotate while sliding up and down, thereby cleaning the inner wall of the tank body 1.
