Description

Technical Field

[0001] This invention relates to the field of material mixing technology, and in particular to a mixing device. Background Technology

[0002] Mixing equipment has a wide range of applications in industrial production, covering multiple fields such as papermaking, chemical industry, metallurgy, building materials, food, pharmaceuticals, ceramics, and batteries. During the mixing process, various raw materials need to be mixed in a predetermined ratio. Some materials need to be mixed under high temperature conditions to promote dispersion, while others need to be cooled to a low temperature environment to counteract the heat generated during high-speed dispersion and prevent modification. Therefore, some raw materials have strict requirements on the temperature during mixing.

[0003] However, existing mixing equipment typically only has heating or cooling functions, rarely possessing both simultaneously. Therefore, existing mixing equipment often cannot complete the mixing of powders at specific temperatures, resulting in uneven material mixing, low mixing efficiency, and consequently affecting the performance of the powder in subsequent processes. Furthermore, when changing materials or performing equipment maintenance, operators need to wait a considerable amount of time for the mixing tank to cool down before performing the necessary operations, a cumbersome process that impacts production efficiency. Summary of the Invention

[0004] The purpose of this invention is to provide a mixing device to alleviate the technical problems existing in the prior art. These devices are usually only equipped with heating or cooling functions, which cannot complete the mixing of powders at a specific temperature. This results in uneven material mixing, low mixing efficiency, and the inability to quickly lower the temperature of the mixing tank during material change or equipment maintenance, affecting the operator's ability to perform corresponding operations and thus reducing production efficiency.

[0011] The hot flow return port and the medium outlet are connected by a hot flow return pipe. The hot flow return pipe is equipped with a hot flow return valve, which is used to open when the cold valve is opened.

[0012] In an optional embodiment, the heat-conducting channel includes a first spiral channel and a second spiral channel;

[0013] The first spiral channel and the second spiral channel extend spirally from one end of the mixing tank to the other end in the same direction of rotation around the axial direction of the mixing tank; one end of the first spiral channel is the medium inlet, and the other end is connected to one end of the second spiral channel, and the other end of the second spiral channel is the medium outlet.

[0014] In an optional embodiment, a flow divider is provided on one side of the mixing tank. The flow divider is provided with a first groove and a second groove. The cold flow outlet and the hot flow outlet are both connected to the medium inlet through the first groove, and the medium outlet is connected to the second groove.

[0015] In an optional embodiment, a medium inflow pipe and a medium outflow pipe are also included, each of which is provided with an inlet and an outlet.

[0016] Both the cold flow outlet and the hot flow outlet are connected to the inlet of the medium inflow pipe, the outlet of the medium inflow pipe is connected to the first groove, and the inlet of the medium outflow pipe is connected to the second groove.

[0017] In an optional embodiment, the diverter plate is annular, the first groove is provided on one side of the diverter plate, and the bottom of the first groove is provided with a first through hole communicating with the annular space of the diverter plate.

[0018] The first through hole has an annular extension and the inner edge of the extension is connected to the outlet of the medium inflow pipe, and the groove of the first groove is connected to the medium inlet.

[0019] In an optional embodiment, the side of the extension opposite to the first groove forms a second groove with the annular space of the diverter plate, and the inlet of the medium outlet pipe communicates with the slot of the second groove.

[0020] The inside of the diverter plate is formed with a return cavity extending circumferentially therein. The circumferential sidewall of the second groove is provided with a second through hole communicating with the return cavity. The outer circumferential wall of the diverter plate is provided with a third through hole communicating with the return cavity. The medium outlet is connected to the third through hole.

[0021] In an optional embodiment, a temperature measuring component is also included, which is disposed on the mixing tank and used to detect the temperature inside the mixing chamber.

[0022] The mixing equipment provided by this invention includes a refrigeration device, a heating device, and a mixing tank. The mixing tank has a mixing chamber inside, and a heat-conducting channel is provided on the side wall of the mixing chamber. The heat-conducting channel has a medium inlet and a medium outlet. The refrigeration device has a cold flow outlet, which is connected to the medium inlet. The refrigeration device is used to supply cooling medium to the heat-conducting channel to exchange heat and lower the temperature of the mixing chamber. The heating device has a hot flow outlet, which is connected to the medium inlet. The heating device is used to supply heating medium to the heat-conducting channel to exchange heat and raise the temperature of the mixing chamber. When mixing powders requiring a high-temperature mixing environment, the powder can be first added to the mixing chamber of the mixing tank of this mixing equipment, and then mixed in the mixing tank. Simultaneously, the heating device is activated and the refrigeration device is turned off. The heating device supplies heating medium to the heat-conducting channel, thereby exchanging heat and raising the temperature of the mixing chamber. This keeps the powder in the mixing chamber in a high-temperature environment, promoting powder dispersion and improving mixing uniformity and efficiency. When mixing powders requiring a low-temperature mixing environment, the powder is placed into the mixing chamber of the mixing tank, and mixing takes place within the tank. Simultaneously, the refrigeration unit is activated and the heating unit is deactivated. The refrigeration unit supplies cooling medium through the heat conduction channel, thereby cooling the mixing chamber and maintaining a low-temperature environment for the powder. This counteracts the heat generated during high-speed dispersion of the powder, preventing powder modification. Therefore, the mixing equipment provided by this invention can perform powder mixing processes not only in high-temperature environments but also in low-temperature environments, meeting the mixing needs of various powders. Furthermore, after mixing, if the mixing tank temperature is high and needs to be changed or maintained, it needs to be cooled to facilitate subsequent operations. In this case, the heating unit is deactivated and the refrigeration unit is activated, supplying cooling medium through the heat conduction channel to rapidly cool the mixing tank, facilitating operations and improving production efficiency.

[0023] Compared with the prior art, the mixing equipment provided by the present invention can have both heating and cooling functions through a refrigeration device and a heating device, which can meet the requirements of high temperature or low temperature environment in the powder mixing process. Moreover, when changing materials or maintaining equipment, the mixing equipment can use the refrigeration device to quickly cool down the mixing tank to facilitate subsequent operations, thereby effectively improving production efficiency.

Detailed Implementation

[0034] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0035] Therefore, the following detailed description of the embodiments of the invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention.

[0036] The following detailed description of some embodiments of the present invention is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0037] Example:

[0038] like Figures 1-5 As shown, the mixing equipment provided in this embodiment includes a refrigeration device 1, a heating device 2, and a mixing tank 3. The mixing tank 3 has a mixing chamber inside, and a heat conduction channel 4 is provided on the side wall of the mixing chamber. The heat conduction channel 4 is provided with a medium inlet 40 and a medium outlet 41. The refrigeration device 1 is provided with a cold flow outlet, which is connected to the medium inlet 40. The refrigeration device 1 is used to supply cooling medium to the heat conduction channel 4 to exchange heat and cool the mixing chamber. The heating device 2 is provided with a hot flow outlet, which is connected to the medium inlet 40. The heating device 2 is used to supply heating medium to the heat conduction channel 4 to exchange heat and raise the temperature of the mixing chamber.

[0039] When mixing powders that require a high-temperature mixing environment, the powders can be first put into the mixing chamber of the mixing tank 3 of the mixing equipment, and then mixed in the mixing tank 3. At the same time, the heating device 2 is started and the cooling device 1 is turned off, so that the heating device 2 can supply heating medium to the heat conduction channel 4, thereby exchanging heat and raising the temperature of the mixing chamber, so that the powders in the mixing chamber are in a high-temperature environment, thereby promoting the dispersion of powders and improving the uniformity and efficiency of mixing.

[0040] When mixing powders requiring a low-temperature mixing environment, the powder can be added to the mixing chamber of mixing tank 3, and then mixed within mixing tank 3. Simultaneously, the refrigeration device 1 is activated and the heating device 2 is turned off. The refrigeration device 1 supplies cooling medium to the heat conduction channel 4, thereby exchanging heat and cooling the mixing chamber. This keeps the powder in the mixing chamber at a low temperature, offsetting the heat generated during high-speed dispersion of the powder and preventing powder modification. Therefore, the mixing equipment provided in this embodiment can achieve powder mixing processes not only in high-temperature environments but also in low-temperature environments, thus meeting the mixing requirements of various powders.

[0041] In addition, after the mixing is completed, if the temperature of the mixing tank 3 is high, it is necessary to cool down the mixing tank 3 to facilitate subsequent operations. At this time, the heating device 2 can be turned off and the cooling device 1 can be turned on. The cooling device 1 can then supply cooling medium to the heat conduction channel 4, so that the mixing tank 3 can be cooled down quickly so that the operators can perform the corresponding operations, thereby improving production efficiency.

[0042] Compared with the prior art, the mixing equipment provided in this embodiment can have both heating and cooling functions through the refrigeration device 1 and the heating device 2, which can meet the requirements of high temperature or low temperature environment in the powder mixing process. In addition, when changing materials or maintaining equipment, the mixing equipment can use the refrigeration device 1 to quickly cool down the mixing tank 3 to facilitate subsequent operations, thereby effectively improving production efficiency.

[0043] There are no restrictions on the specific structure of the refrigeration device 1 and the heating device 2, as long as they can achieve the functions of refrigeration and heating. For example, the refrigeration device 1 can be a refrigeration mold temperature controller, and the heating device 2 can be a heating mold temperature controller.

[0044] It should be noted that the mixing equipment provided in this embodiment may also include a stirring component 5, such as... Figure 1 As shown, the stirring assembly 5 includes a first motor 50 and a stirring blade 51. The output shaft of the first motor 50 is connected to the stirring blade 51, and the stirring blade 51 can extend into the mixing chamber of the mixing tank 3. The stirring blade 51 is used to rotate in the mixing chamber under the drive of the first motor 50, thereby stirring the powder in the mixing chamber, achieving the purpose of dispersing the powder and further improving the powder mixing efficiency.

[0045] In addition, such as Figure 1 and Figure 2 As shown, the top of the mixing tank 3 may be provided with a tank opening, and a cover plate 30 is provided at the tank opening. The cover plate 30 is used to close or open the tank opening. The stirring blade 51 may be provided on the side of the cover plate 30 facing the mixing chamber. The output end of the first motor 50 passes through the perforation on the cover plate 30 and is connected to the stirring blade 51. When the cover plate 30 closes the tank opening, the stirring blade 51 extends into the mixing chamber of the mixing tank 3; when the cover plate 30 opens the tank opening, the stirring blade 51 retracts from the mixing chamber along with the cover plate 30.

[0046] Furthermore, the stirring assembly 5 may also include a transmission structure 52 and a first transmission shaft 53. The transmission structure 52 is connected between the output end of the first motor 50 and the first transmission shaft 53. The stirring blades 51 are fixed to the shaft of the first transmission shaft 53 and extend spirally along the axial direction of the first transmission shaft 53.

[0047] The transmission structure 52 can be a transmission mechanism consisting of a transmission belt, a driving wheel and a driven wheel. The first motor 50 drives the first transmission shaft 53 to rotate through the transmission structure 52, thereby driving the stirring blades 51 on the first transmission shaft 53 to rotate.

[0048] To further improve mixing efficiency, such as Figure 2 As shown, the mixing equipment provided in this embodiment may also include a second motor 6 and a second transmission shaft 60. The output end of the second motor 6 is connected to the second transmission shaft 60, and the second transmission shaft 60 is connected to the bottom of the mixing tank 3. The second motor 6 is used to drive the mixing tank 3 to rotate through the second transmission shaft 60, thereby cooperating with the stirring blades 51 to effectively improve the mixing uniformity and mixing efficiency of the powder in the mixing chamber.

[0049] like Figure 1 As shown, the mixing equipment provided in this embodiment may further include a base 7, on which the mixing tank 3 is mounted. A switch drive assembly may also be mounted on the base 7, and the cover plate 30 is connected to the output terminal of the switch drive assembly. The switch drive assembly is used to drive the cover plate 30 to move closer to or further away from the mixing tank 3, so that the cover plate 30 opens or closes the opening of the mixing tank 3.

[0050] The switch drive assembly can be a telescopic actuator such as a hydraulic cylinder or a pneumatic cylinder. When the cover plate 30 is hinged to one side of the tank opening of the mixing tank 3, the switch drive assembly can also be a hydraulic swing cylinder.

[0051] In this embodiment, the refrigeration device 1 is also provided with a cold flow return port, which is connected to the medium outlet 41; the heating device 2 is also provided with a hot flow return port, which is connected to the medium outlet 41.

[0052] The cold flow return port in the refrigeration device 1 is connected to the medium outlet 41, which allows the medium in the heat conduction channel 4 at the mixing tank 3 to flow back to the refrigeration device 1 after mixing is completed, so that it can be used again after re-cooling; the hot flow return port in the heating device 2 is connected to the medium outlet 41, which allows the medium in the heat conduction channel 4 at the mixing tank 3 to flow back to the heating device 2 after mixing is completed, so that it can be used again after re-heating.

[0053] As can be seen, the cold flow return port and the hot flow return port are connected to the medium outlet 41, which can achieve the purpose of recovering the medium for recycling and effectively reduce resource waste.

[0054] Furthermore, such as Figure 1 As shown, the cold flow outlet and the medium inlet 40 are connected by a cold flow pipe 10, and a cold valve 100 is provided on the cold flow pipe 10; the hot flow outlet and the medium inlet 40 are connected by a hot flow pipe 20, and a hot valve 200 is provided on the hot flow pipe 20; either the cold valve 100 or the hot valve 200 can be opened.

[0055] Opening either the cold valve 100 or the hot valve 200 allows either the cold flow pipe 10 or the hot flow pipe 20 to be connected, thereby allowing either the refrigeration device 1 or the heating device 2 to supply the medium to the heat conduction channel 4 at the mixing tank 3. This ensures that the environment inside the mixing chamber of the mixing tank 3 is either a high-temperature environment or a low-temperature environment, thus meeting the mixing requirements of the corresponding powder and preventing the refrigeration device 1 and the heating device 2 from simultaneously supplying the medium to the heat conduction channel 4 and interfering with each other.

[0056] like Figure 1 As shown, the cold flow return port and the medium outlet 41 are connected by a cold flow return pipe 11. The cold flow return pipe 11 is equipped with a cold flow return valve 110, which is used to open when the hot valve 200 is opened. The hot flow return port and the medium outlet 41 are connected by a hot flow return pipe 21. The hot flow return pipe 21 is equipped with a hot flow return valve 210, which is used to open when the cold valve 100 is opened.

[0057] The cold return valve 110 is used to control the opening and closing of the cold flow return pipe 11, thereby controlling the process of the medium returning to the refrigeration unit 1; the hot return valve 210 is used to control the opening and closing of the hot flow return pipe 21, thereby controlling the process of the medium returning to the heating unit 2.

[0058] Since the mixing environment is a high-temperature environment, that is, when the heating device 2 is working, the heating medium supplied by the heating device 2 to the heat channel 4 will exchange heat and raise the temperature of the mixing chamber. Based on the law of conservation of heat, after the mixing chamber is heated by heat exchange, the medium will cool down. Therefore, the cold return valve 110 opens when the hot valve 200 is opened, which allows the cooled medium to flow back to the refrigeration device 1 through the cold return pipe 11. Thus, the refrigeration device 1 can cool the return medium into a cooling medium with less power consumption.

[0059] Compared to returning the cooled medium to the heating device 2 to be reheated as a heating medium, returning the cooled medium to the cooling device 1 to be cooled as a cooling medium consumes less energy and can effectively reduce energy consumption. Therefore, in this embodiment, it is preferred that the cold return valve 110 is opened when the hot valve 200 is opened.

[0060] Correspondingly, since the mixing environment is at a low temperature, that is, when the refrigeration device 1 is working, the cooling medium supplied by the refrigeration device 1 to the heat channel 4 will exchange heat and cool down the mixing chamber. Based on the law of conservation of heat, after the mixing chamber is cooled down by heat exchange, the medium will heat up. Therefore, the heat return valve 210 opens when the cold valve 100 is opened, which allows the heated medium to flow back to the heating device 2 through the heat return pipe 21, so that the heating device 2 can heat the return medium into a heating medium with less power.

[0061] Compared to returning the heated medium to the refrigeration device 1 to cool it down again as a cooling medium, returning the heated medium to the heating device 2 to heat it up as a heating medium consumes less energy and can further effectively reduce energy consumption. Therefore, in this embodiment, it is preferred that the heat return valve 210 is opened when the cold valve 100 is opened.

[0062] like Figure 4 and Figure 5 As shown, the heat conduction channel 4 includes a first spiral channel 42 and a second spiral channel 43; the first spiral channel 42 and the second spiral channel 43 extend spirally from one end of the mixing tank 3 to the other end in the same direction of rotation around the axial direction of the mixing tank 3; and one end of the first spiral channel 42 is the medium inlet 40, the other end is connected to one end of the second spiral channel 43, and the other end of the second spiral channel 43 is the medium outlet 41.

[0063] The first spiral channel 42 is used to allow the heating or cooling medium to flow around the mixing tank 3 during the mixing process, thereby exchanging heat with the powder in the mixing chamber of the mixing tank 3. The second spiral channel 43 is used to allow the heat-exchanged medium to flow out from the side of the mixing tank 3 after the mixing is completed.

[0064] Since the first spiral channel 42 and the second spiral channel 43 extend spirally around the mixing tank 3 in the same direction of rotation, and the other end of the first spiral channel 42 is connected to one end of the second spiral channel 43, the heating medium or cooling medium will flow from one end of the mixing tank 3 to the other end of the mixing tank 3 through the medium inlet 40 along the first spiral channel 42 during the heat exchange process. After heat exchange, it will flow in the opposite direction in the second spiral channel 43 from the other end of the mixing tank 3 to one end, and finally flow out from the medium outlet 41.

[0065] For example, such as Figure 5 As shown, the end of the first spiral channel 42 serving as the medium inlet 40 and the end of the second spiral channel 43 serving as the medium outlet 41 are both located at the bottom of the mixing tank 3, and the other ends of the first spiral channel 42 and the second spiral channel 43 are both located at the top of the mixing tank 3. During the heat exchange process, the heating medium or cooling medium will flow from the medium inlet 40 in the first spiral channel 42 from the bottom to the top of the mixing tank 3. That is, during the heat exchange process, the medium will flow from bottom to top. After the heat exchange, the medium will flow in the opposite direction, that is, it will flow from top to bottom in the second spiral channel 43 to the bottom of the mixing tank 3, and finally flow out from the medium outlet 41 at the bottom of the mixing tank 3.

[0066] The first spiral channel 42 and the second spiral channel 43 can be formed directly by a pipe surrounding the mixing tank 3, or by a channel excavated inside the side wall of the mixing tank 3.

[0067] To facilitate the formation of the first spiral channel 42 and the second spiral channel 43 within the side wall of the mixing tank 3, such as Figure 3 As shown, in this embodiment, the mixing tank 3 preferably includes two sidewalls, namely an inner sidewall and an outer sidewall. The outer sidewall is sleeved outside the inner sidewall and forms an interlayer between the outer sidewall and the inner sidewall. At this time, by setting a spiral blade in the interlayer and fixing the spiral blade between the inner sidewall and the outer sidewall, the first spiral channel 42 and the second spiral channel 43 can be formed.

[0068] To improve heat exchange efficiency while preventing the external ambient temperature from affecting the temperature inside the mixing chamber, the inner sidewall of the mixing tank 3 can be made of a thermally conductive material with good thermal conductivity, while the outer sidewall of the mixing tank 3 can be made of an insulating material. Alternatively, both the inner and outer sidewalls of the mixing tank 3 can be made of thermally conductive materials with good thermal conductivity, but the outer sidewall of the mixing tank 3 can be covered with an insulating layer.

[0069] When the outer sidewall of the mixing tank 3 is also covered with an insulation layer, in order to improve the installation stability of the insulation layer and extend its service life, the mixing tank 3 may also include three sidewalls, namely an inner sidewall, an outer sidewall, and a reinforced sidewall. The outer sidewall is fitted outside the inner sidewall and forms a first interlayer 31 between the outer sidewall and the inner sidewall. The reinforced sidewall is fitted outside the outer sidewall and forms a second interlayer 32 between the outer sidewall and the outer sidewall. The first interlayer 31 is used to install spiral blades to form a first spiral channel 42 and a second spiral channel 43. The second interlayer 32 is used to install the insulation layer.

[0070] The insulation layer can be made of thermal insulation cotton.

[0071] It should be noted that the structure of the heat conduction channel 4 is not limited to the above-mentioned form including the first spiral channel 42 and the second spiral channel 43. The heat conduction channel 4 can also be formed directly by the interlayer between the double sidewalls of the mixing tank 3, or the heat conduction channel 4 can be formed by a pipe embedded in the sidewall of the mixing tank 3.

[0072] like Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, a flow divider plate 8 is provided on one side of the mixing tank 3. The flow divider plate 8 is provided with a first groove 80 and a second groove 81. The cold flow outlet and the hot flow outlet are both connected to the medium inlet 40 through the first groove 80, and the medium outlet 41 is connected to the second groove 81.

[0073] To improve the heat exchange efficiency of the heat conduction channel 4 to the mixing chamber inside the mixing tank 3, there can be multiple medium inlets 40 and medium outlets 41 provided on the heat conduction channel 4. The multiple medium inlets 40 are distributed at intervals along the circumference of the mixing tank 3, and the multiple medium inlets 40 are all connected to the first groove 80; the multiple medium outlets 41 are distributed at intervals along the circumference of the mixing tank 3, and the multiple medium outlets 41 are all connected to the second groove 81.

[0074] During the flow of the heating medium from the hot outlet to the medium inlet 40, the heating medium first enters the first groove 80, and then flows through the first groove 80 to multiple medium inlets 40 simultaneously. This ensures that the heating medium flows into the periphery of the mixing tank 3 simultaneously, effectively improving heating efficiency. Similarly, during the flow of the cooling medium from the cold outlet to the medium inlet 40, the cooling medium first enters the first groove 80, and then flows through the first groove 80 to multiple medium inlets 40 simultaneously. This ensures that the cooling medium flows into the periphery of the mixing tank 3 simultaneously, effectively improving cooling efficiency.

[0075] When mixing is complete and the heat-exchanged medium needs to flow out of the heat conduction channel 4, the medium in the heat conduction channel 4 can simultaneously flow to the second groove 81 through multiple medium outlets 41 on the circumference of the mixing tank 3, thereby effectively improving the medium outflow efficiency. The second groove 81 can be used to store the medium, or it can be connected to an external collection container for medium collection. To recycle the medium and save resources, the second groove 81 can also be connected to the cold flow return pipe 11 and the hot flow return pipe 21.

[0076] It should be noted that, in order to prevent the medium inflow and outflow processes from interfering with each other, the first groove 80 and the second groove 81 on the distribution plate 8 need to be set separately from each other. At this time, the first groove 80 and the second groove 81 will not be connected to each other, which can effectively prevent the medium before heat exchange and the medium after heat exchange from mixing and affecting each other.

[0077] It can be seen that setting the diversion plate 8 can effectively improve the heat exchange efficiency of the heating medium and the cooling medium during the heat exchange process, and can also improve the outflow efficiency of the medium after heat exchange. Therefore, in this embodiment, it is preferable to set the diversion plate 8 below the mixing tank 3 to improve the working efficiency of the mixing equipment.

[0078] like Figure 3 As shown, the mixing equipment provided in this embodiment also includes a medium inflow pipe 400 and a medium outflow pipe 410. Both the medium inflow pipe 400 and the medium outflow pipe 410 are provided with an inlet and an outlet. The cold flow outlet and the hot flow outlet are both connected to the inlet of the medium inflow pipe 400, the outlet of the medium inflow pipe 400 is connected to the first groove 80, and the inlet of the medium outflow pipe 410 is connected to the second groove 81.

[0079] The medium inflow pipe 400 is used to connect the cold flow outlet and the first groove 80, and to connect the hot flow outlet and the first groove 80. When the cold flow outlet and the medium inlet 40 are connected by the cold flow pipe 10, and the hot flow outlet and the medium inlet 40 are connected by the hot flow pipe 20, one end of the cold flow pipe 10 can be connected to the cold flow outlet, one end of the hot flow pipe 20 can be connected to the hot flow outlet, and the other ends of the cold flow pipe 10 and the hot flow pipe 20 are both connected to the inlet of the medium inflow pipe 400. At this time, the cold flow pipe 10, the hot flow pipe 20 and the medium inflow pipe 400 can be connected to each other by a three-way valve 9 such as a three-way ball valve.

[0080] The medium outlet pipe 410 is used to connect with the second groove 81 as a medium discharge pipe. When the refrigeration device 1 is also provided with a cold flow return port and the cold flow return port is connected to the medium outlet 41 through the cold flow return pipe 11, and the heating device 2 is also provided with a hot flow return port and the hot flow return port is connected to the medium outlet 41 through the hot flow return pipe 21, one end of the cold flow return pipe 11 can be connected to the cold flow return port, one end of the hot flow return pipe 21 can be connected to the hot flow return port, and the other end of the cold flow return pipe 11 and the other end of the hot flow return pipe 21 are both connected to the outlet of the medium outlet pipe 410. At this time, the cold flow return pipe 11, the hot flow return pipe 21 and the medium outlet pipe 410 can also be connected to each other through a three-way valve 9 such as a three-way ball valve.

[0081] It should be noted that when the mixing equipment provided in this embodiment also includes a second motor 6 and a second drive shaft 60, in order to prevent the above-mentioned pipeline from interfering with the process of the second motor 6 driving the mixing tank 3 to rotate, such as Figure 2 As shown, the medium inflow pipe 400 can be interconnected with the corresponding three-way valve 9 via the rotary joint 90, and correspondingly, the medium outflow pipe 410 can also be interconnected with the corresponding three-way valve 9 via the rotary joint 90.

[0082] like Figure 6 and Figure 7 As shown, the distribution plate 8 is annular, the first groove 80 is provided on one side of the distribution plate 8 and the bottom of the groove of the first groove 80 is provided with a first through hole 800 that communicates with the inner space of the annular space of the distribution plate 8; the first through hole 800 is provided with an annular extension 801 and the inner edge of the extension 801 communicates with the outlet of the medium inflow pipe 400, and the groove opening of the first groove 80 communicates with the medium inlet 40.

[0083] During the flow of heating or cooling medium into the heat-guiding channel 4, the heating or cooling medium will first flow through its corresponding cold flow pipe 10 or hot flow pipe 20 to the medium inlet pipe 400. Since the outlet of the medium inlet pipe 400 is connected to the inner edge of the extension 801, and the extension 801 is located in the first through hole 800 at the bottom of the first groove 80, the heating or cooling medium flowing into the medium inlet pipe 400 can continue to flow into the first groove 80, and then flow through the groove opening of the first groove 80 to the medium inlet 40 of the heat-guiding channel 4.

[0084] The side of the diverter plate 8 facing the mixing tank 3 is its top, and the side facing away from the mixing tank 3 is its bottom. To facilitate the connection between the first groove 80 and the medium inlet 40, the first groove 80 can be located on the top of the diverter plate 8. Correspondingly, the extension 801 is also located on the top of the diverter plate 8.

[0085] Furthermore, the first groove 80 can be cross-shaped, and there can be four medium inlets 40 at the bottom of the mixing tank 3, and the four medium inlets 40 are connected to the four ends of the first groove 80 one by one.

[0086] Since the first through hole 800 is provided with an annular extension 801 and the inner edge of the extension 801 is connected to the outlet of the medium inflow pipe 400, in order to facilitate the assembly of the diverter plate 8 and the medium inflow pipe 400, the outlet of the medium inflow pipe 400 can pass through the annular space of the diverter plate 8 and be fixedly connected to the extension 801 at the top of the diverter plate 8, so that the hollow part of the extension 801 is connected to the medium inflow pipe 400.

[0087] Furthermore, to improve the connection stability and ease of connection between the extension 801 and the outlet of the medium inflow pipe 400, the extension 801 and the outlet of the medium inflow pipe 400 can be interconnected via a tubular connector. Specifically, the top end of the tubular connector is flush with and fixedly connected to the inner edge of the extension 801, the bottom end of the tubular connector is flush with the bottom of the distribution plate 8, and the bottom end of the tubular connector is fixedly connected to the outlet of the medium inflow pipe 400.

[0088] like Figure 7 As shown, the side of the extension 801 facing away from the first groove 80 forms a second groove 81 with the inner space of the diverter plate 8. The inlet of the medium outlet pipe 410 is connected to the groove opening of the second groove 81. A return cavity extending circumferentially is formed inside the diverter plate 8. The circumferential sidewall of the second groove 81 is provided with a second through hole 810 communicating with the return cavity. The outer circumferential wall of the diverter plate 8 is provided with a third through hole 82 communicating with the return cavity. The medium outlet 41 is connected to the third through hole 82.

[0089] When the mixing is finished and the heat-exchanged medium needs to flow out, the heat-exchanged medium will first flow through the medium outlet 41 of the heat conduction channel 4 to the third through hole 82 on the outer peripheral wall of the distribution plate 8, and then enter the return cavity of the distribution plate 8. Since the circumferential side wall of the second groove 81 is provided with a second through hole 810 that communicates with the return cavity, after the heat-exchanged medium flows into the return cavity through the third through hole 82, it will continue to flow through the second through hole 810 to the second groove 81, and then flow through the slot of the second groove 81 to the inlet of the medium outlet pipe 410, and finally be discharged through the medium outlet pipe 410.

[0090] The second groove 81 is formed by the side of the extension 801 opposite to the first groove 80 and the inner space of the diverter plate 8. This not only allows the first groove 80 and the second groove 81 to be located on both sides of the diverter plate 8 to separate the first groove 80 and the second groove 81, but also simplifies the structure of the diverter plate 8.

[0091] Since the opening of the second groove 81 faces downwards from the distribution plate 8, it is convenient to connect the second groove 81 to the inlet of the medium outlet pipe 410 below the distribution plate 8. Furthermore, since the outlet of the medium inflow pipe 400 passes through the annular space of the distribution plate 8 and connects to the hollow of the extension 801, and the second groove 81 is formed by the extension 801 and the annular space of the distribution plate 8, the edge of the groove opening of the second groove 81 is located outside the outlet of the medium inflow pipe 400. The diameter of the second groove 81 is larger than the diameter of the outlet of the medium inflow pipe 400. Therefore, the medium outlet pipe 410 can be fitted over the medium inflow pipe 400, and then the inlet of the medium outlet pipe 410 can be fixed and connected to the groove opening of the second groove 81.

[0092] When the media outlet pipe 410 is fitted outside the media inlet pipe 400, the space between the inner wall of the media outlet pipe 410 and the outer wall of the media inlet pipe 400 serves as a media outlet channel. Although the media outlet space is reduced at this time, it can effectively improve the neatness of the assembly of the media inlet pipe 400 and the media outlet pipe 410, simplify the piping structure of the mixing equipment, and reduce the space occupied by the media inlet pipe 400 and the media outlet pipe 410. In addition, the media outlet pipe 410 can also protect the media inlet pipe 400 at this time, extending the service life of the media inlet pipe 400.

[0093] The second groove 81 has a second through hole 810 communicating with the return cavity on its circumferential sidewall, and a third through hole 82 communicating with the return cavity on its outer circumferential wall of the diverter plate 8. The medium outlet 41 is connected to the third through hole 82, so that the medium outlet 41 and the second groove 81 can be interconnected by using the return cavity inside the diverter plate 8.

[0094] like Figure 1 and Figure 8As shown, the mixing equipment provided in this embodiment also includes a temperature measuring component 300, which is disposed on the mixing tank 3 and is used to detect the temperature inside the mixing chamber.

[0095] The temperature measuring component 300 is used to detect the temperature inside the mixing chamber in real time so that the staff can control the ambient temperature during the mixing process in a timely manner, thereby facilitating the staff to turn the heating device 2 or the cooling device 1 on or off in a timely manner, so that the mixing ambient temperature is within the target range.

[0096] Furthermore, the mixing equipment provided in this embodiment may also include a control device. The temperature measuring component 300, cold valve 100, hot valve 200, cold return valve 110, and hot return valve 210 can all be connected to the control device. The control device has a preset target temperature range. The control device is used to receive the temperature value detected by the temperature measuring component 300 and determine whether the temperature in the mixing chamber exceeds the target temperature range based on the temperature value. In addition, the control device can also control the cold valve 100 and the hot return valve 210 to close when the temperature in the mixing chamber is lower than the minimum value of the target temperature range. The control device closes the heating valve 200 and the cold return valve 110, and simultaneously opens the heating valve 200 and the cold return valve 110, so that the heating device 2 supplies heating medium to the heat channel 4; when the temperature in the mixing chamber is within the target temperature range, the control device closes the cold valve 100, the hot return valve 210, the hot valve 200, and the cold return valve 110; when the temperature in the mixing chamber is higher than the highest value of the target temperature range, the control device closes the hot valve 200 and the cold return valve 110, and simultaneously opens the cold valve 100 and the hot return valve 210, so that the cooling device 1 supplies cooling medium to the heat channel 4.

[0097] In addition, both the heating device 2 and the cooling device 1 can be equipped with a gear switch, and both the gear switch of the heating device 2 and the gear switch of the cooling device 1 can be connected to the control device. The control device can also adjust the gear switch of the heating device 2 or the gear switch of the cooling device 1 according to the temperature value detected by the temperature measuring component 300 when the temperature value exceeds the target temperature range, so as to adjust the heating power of the heating device 2 or the cooling power of the cooling device 1 so that the temperature in the mixing chamber is maintained within the target temperature range.

[0098] The temperature measuring component 300 can be a temperature sensor, and the control device can be a microcontroller or a programmable logic controller.

[0099] As can be seen, the mixing equipment provided in this embodiment can also achieve precise temperature control by cooperating with the temperature measuring component 300 and the control device, which can ensure that the materials are mixed within the optimal temperature range, thereby obtaining the best dispersion, mixing and fiberization effect, and avoiding poor mixing effect due to excessively high or low ambient temperature.

[0100] When the mixing tank 3 is equipped with a cover plate 30, in order to facilitate the detection of the temperature inside the mixing chamber, the temperature measuring component 300 can be installed on the cover plate 30, and the temperature measuring probe of the temperature measuring component 300 extends into the mixing chamber.

[0101] Specifically, the cover plate 30 may be provided with a threaded hole, and the temperature measuring component 300 is provided with an external thread that matches the threaded hole. In this case, the temperature measuring component 300 is installed on the cover plate 30 by means of threaded connection.

[0102] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
