[0002] A mixer is a mechanical device that mixes two or more materials evenly.

[0003] Currently, mixers do not have heating functions, which cannot meet the requirements of mixing certain types of materials at specific temperature environments.

The mixing body is disposed inside the device body, and a heating chamber is formed between the device body and the mixing body. The heat-generating device is connected to the heating chamber and is used to introduce hot air into the heating chamber to achieve heat-generating heating of the mixing body.

[0006] In some embodiments, the main body of the device has an air inlet and an air outlet communicating with the heating chamber, and the air-heating device is connected to the air inlet and the air outlet through an air pipe.

[0007] In some embodiments, the device body includes a first door and a second door located on the outer periphery of the heating cavity, the second door being rotatable and openable relative to the first door.

[0008] In some embodiments, the main body of the device is provided with a second door on both sides of the heating cavity, the air inlet and the air outlet are located on the same side of the heating cavity and the air inlet and the air outlet are opened on different second doors.

Detailed Implementation

[0024] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0025] To enable those skilled in the art to better understand the present application, the present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0026] Existing mixing devices do not have heating functions and mix materials at room temperature, with the mixture heating up due to friction during the mixing process. On the one hand, the mixing effect changes when the ambient temperature changes (due to temperature differences between winter and summer); on the other hand, when materials need to be mixed at a specific temperature, traditional mixing devices cannot achieve temperature control of the mixing environment.

[0027] Specifically, certain types of materials require mixing at specific temperature conditions to achieve the desired effect, such as maintaining the ambient temperature between 60°C and 80°C during the mixing process. Therefore, at least one additional step is needed before mixing: preheating the materials to the predetermined temperature range before mixing. This increases both time and equipment costs.

[0028] To address the aforementioned technical problems, this application provides a temperature-controlled mixing device, which enables materials to be mixed directly without requiring preheating by other equipment.

[0029] Please refer to Figures 1 to 4 ,in, Figure 1 This is a schematic diagram of the structure of the temperature-controlled mixing device provided in the embodiments of this application. Figure 2 This is an internal structural diagram of the temperature-controlled mixing device provided in the embodiments of this application. Figure 3 for Figure 1 Front view of a medium-temperature controlled mixing device. Figure 4 for Figure 2 A schematic diagram of the structure of the first gate body and the flow guiding component.

[0030] The temperature-controlled mixing equipment mainly includes a main body 1, a mixing body 2, and a heating element 3. The mixing body 2 is located inside the main body 1, and a heating chamber 11 is formed between the main body 1 and the mixing body 2. The main body 1 and the mixing body 2 are the basic components of the temperature-controlled mixing equipment for realizing the mixing function (stirring, granulation, etc.). The mixing body 2 mainly includes a mixing cylinder 21, which serves to load materials. The main body 1 is equivalent to the part of the mixer excluding the mixing cylinder 21, and it drives the mixing cylinder 21 to rotate for material mixing. Details regarding the main body 1 and the mixing body 2 are not improvements to this embodiment and can be found in existing technologies; they will not be elaborated upon here.

[0031] In one configuration, the mixing body 2, or mixing cylinder 21, has a circular cross-sectional shape. A heating cavity 11 is formed between the inner wall of the equipment body 1 and the outer wall of the mixing cylinder 21. The heating cavity 11 can have an annular cross-sectional shape. The mixing cylinder 21 is surrounded and enclosed by the heating cavity 11 at all circumferential angles. The mixing cylinder 21 should be made of a material with good thermal conductivity.

[0032] The air-heating device 3 is an additional component of the temperature-controlled mixing equipment to realize the added air-heating function. The air-heating device 3 is connected to the heating chamber 11. The air-heating device 3 can heat and blow the airflow, thereby enabling the air-heating device 3 to introduce hot air into the heating chamber 11, and then heat the mixing body 2 in the heating chamber 11 through heat conduction.

[0033] In one scenario, the hot air generated by the air-heating device 3 flows through the heating chamber 11. Under the action of heat conduction, the mixing cylinder 21 is heated by the hot air, thereby raising the ambient temperature of the mixing cylinder 21 as the material, thus achieving the purpose of heating the material.

[0034] During the use of this temperature-controlled mixing equipment, the mixing body 2, namely the mixing cylinder 21, is used to load and mix the materials, and the air-heating device 3 is used to heat the environment in which the materials are located, thereby achieving mixing of the materials at the set ambient temperature.

[0035] In one scenario, before adding materials to the mixing body 2 (mixing cylinder 21), hot air is introduced into the heating chamber 11 using a hot air heating device 3 to heat the mixing body 2 in the form of hot air, and the temperature is controlled within a set range. Then, materials are added to the mixing body 2. At this point, the materials can be directly mixed without needing to undergo preheating treatment by other equipment. Based on the above structural and process description, this temperature-controlled mixing equipment can control the ambient temperature during material mixing, ensuring the mixing effect; the hot air has a fast flow rate, resulting in high heating efficiency and uniform temperature distribution.

[0036] Furthermore, the temperature-controlled mixing equipment also includes a controller and sensors. The controller is connected to the sensors and the heating element 3. The sensors monitor the temperature of the mixing body 2, i.e., the mixing drum 21, to obtain the temperature of the material's environment. A temperature control range is set in the controller. Based on the temperature monitored by the sensors and the set temperature control range, the controller controls the operation of the heating element 3, thereby maintaining the temperature of the material's environment within the set temperature control range. In some cases, the sensor is a temperature sensor, which is installed on the outer wall of the mixing drum 21 and is connected to the controller via a signal connection. The controller is also connected to the heating element 3 via a signal connection. Based on the set temperature control range and the temperature information monitored by the temperature sensor, the controller sends control signals to the heating element 3 to change its operating state, such as turning it on and off, and adjusting the heating level.

[0037] It should be noted that the temperature control strategy of the above-mentioned temperature-controlled mixing equipment is suitable for controlling the ambient temperature of the material to be within the temperature range required for heating, so as to ensure that the mixing effect of the material is sufficient and meets the standards. On this basis, it is also suitable for balancing the ambient temperature of the material. For example, the material will heat up due to friction during the mixing process. At this time, by monitoring and controlling the temperature, the temperature can still be controlled within the expected range, which is equivalent to reducing the heating function of the air-heating device 3 and achieving the effect of balancing the temperature of the material.

[0038] Please continue to refer to this. Figure 2 and Figure 3 In some embodiments, the main body 1 of the device has an air inlet 12 and an air outlet 13, and the air inlet 12 and the air outlet 13 are connected to the heating chamber 11 inside the main body 1 at different positions.

[0039] In this embodiment, the air-heating device 3 is connected to the air inlet 12 and the air outlet 13 through an air pipe. At this time, the air-heating device 3 blows hot air from the air outlet 13 into the heating chamber 11 inside the main body of the equipment. The air in the heating chamber 11 inside the main body of the equipment enters the air-heating device 3 through the air inlet 12. The air-heating device 3 and the heating chamber 11 inside the main body of the equipment form an internal gas circulation. That is to say, the air-heating device 3 heats the air in the heating chamber 11 inside the main body of the equipment and then blows it back into the heating chamber 11. This setting helps to improve the heating efficiency, save energy and protect the environment, and has a good heat preservation effect after heating.

[0040] It should be noted that this embodiment does not limit the positional relationship between the air-heating device 3 and the main body 1. That is to say, whether the air-heating device 3 is assembled with the main body 1 or not assembled with the main body 1, both are permissible implementations of the air-heating device 3 and should fall within the scope of this embodiment.

[0041] Please continue to refer to this. Figure 1 For example, the air-heating device 3 is installed on the main body 1 of the equipment. At this time, the air-heating device 3 and the main body 1 of the equipment are assembled together. This arrangement has a stronger overall integrity and allows for unified management of the main body 1 of the equipment and the air-heating device 3.

[0042] In some embodiments, the air-heating device 3 includes a heating component 31, an air inlet pipe 33, and an air outlet pipe 34. The heating component 31 has an air inlet end and an air outlet end. The air inlet pipe 33 connects the air inlet end of the heating component 31 to the air outlet 13 of the device body 1. The air outlet pipe 34 connects the air outlet end of the heating component 31 to the air inlet 12 of the device body 1.

[0043] Furthermore, the air-heating device 3 also includes a fan assembly 32. The function of the fan assembly 32 is to promote the air in the heating chamber 11 inside the main body of the equipment to enter the heating component 31 for heating through the air outlet 13 and the air inlet 33, and to promote the hot air obtained by the heating component 31 to be blown into the heating chamber 11 inside the main body of the equipment through the air outlet 34 and the air inlet 12.

[0044] It should be noted that this embodiment does not limit the location of the fan assembly 32. That is to say, the fan assembly 32 can be located between the air outlet 13 and the air inlet pipe 33, between the air outlet pipe 34 and the air inlet 12, or even in the main body 1 or the heating assembly 31. These are all permissible implementations of the fan assembly 32 and should be within the scope of this embodiment.

[0045] For example, the fan assembly 32 is connected to the air outlet 13, and the air inlet of the heating assembly 31 is connected to the fan assembly 32 through the air inlet pipe 33. In this case, the fan assembly 32 is positioned between the air outlet 13 and the air inlet pipe 33. The fan assembly 32 blows air from the heating chamber 11 inside the equipment body 1 into the heating assembly 31 for heating, and blows the hot air heated by the heating assembly 31 into the heating chamber 11 inside the equipment body 1. In some cases, the heating assembly 31 includes a housing and a heating pipe located inside the housing; the fan assembly 32 includes a high-temperature resistant fan.

[0046] In one specific embodiment, the main body of the device 1 includes a first door 14 and a second door 15 located on the outer periphery of the heating chamber 11, and the second door 15 can be rotated and opened relative to the first door 14.

[0047] like Figure 2 As shown, the first door 14, the second door 15, and the support 16 are located on the outer periphery of the heating chamber 11, together forming a wrapping and surrounding effect on the outer periphery of the heating chamber 11. In addition, the main body 1 of the equipment also includes a base and a bottom plate. The bottom plate and the support 16 are fixed to the upper side of the base, and the first door 14 is fixed to the upper side of the bottom plate. The second door 15 is rotatably connected to the first door 14 via a hinge, or the second door 15 is rotatably connected to the support 16 via a hinge. In use, the second door 15 can rotate and open relative to the first door 14. After opening the second door 15, the mixing cylinder 21 in the heating chamber 11 is exposed, allowing for observation and other operations on the mixing cylinder 21 and the materials within it.

[0048] Furthermore, the main body 1 of the equipment is provided with second doors 15 on both sides opposite to the heating chamber 11, corresponding to... Figure 2 The front and rear sides of the mixing cylinder 21. The air inlet 12 and air outlet 13 are located on the same side of the heating chamber 11, corresponding to... Figure 2 The rear side of the mixing cylinder 21. The air inlet 12 and air outlet 13 are located on different second doors 15, corresponding to... Figure 2 The two second doors 15 on the rear side of the mixing cylinder 21 are arranged to open and close as double doors. In addition, there are also two second doors 15 on the front side of the mixing cylinder 21, which are also double doors. The mixing cylinder 21 has openings at corresponding positions and is equipped with hinged doors.

[0049] For better technical results, the first door 14, the second door 15, and the support 16 are insulated. During the heating process, the heating chamber 11, as a relatively sealed space, transfers heat to the mixing cylinder 21 to the maximum extent, thereby achieving rapid heating.

[0050] In one specific implementation, the distance between the air inlet 12 and the bottom surface of the equipment body 1 is less than the distance between the air outlet 13 and the bottom surface of the equipment body 1.

[0051] In this embodiment, the height of the air inlet 12 is lower than the height of the air outlet 13, thereby defining the air inlet and outlet positions into the heating chamber 11 inside the main body 1. During use, based on the airflow effect of the fan assembly 32, hot air enters the heating chamber 11 from the lower position. After flowing through the heating chamber 11 and heating the mixing cylinder 21, the hot air leaves the heating chamber 11 from the higher position. This arrangement helps to expand the flow range of hot air in the heating chamber 11, improving the sufficiency of hot air flow. Furthermore, since the material in the mixing cylinder 21 is mostly concentrated at the lower position, directly blowing hot air to the lower position helps to improve energy utilization efficiency.

[0052] In addition, the axial direction of the air inlet 12 coincides with the tangential direction of the heating chamber 11 at the air inlet 12. With this arrangement, hot air is blown into the heating chamber 11 along the tangential direction. On the one hand, the kinetic energy loss of the hot air is small, and on the other hand, the hot air circulates in a circular shape in the heating chamber 11, providing comprehensive and sufficient coverage of the space.

[0053] Furthermore, the inner wall of the main body 1 of the equipment is provided with a flow guiding component 17. The function of the flow guiding component 17 is to guide the airflow and promote the hot air to flow regularly and orderly in the heating chamber 11, thereby improving the uniformity of temperature distribution and increasing the heating efficiency.

[0054] For example, a flow guide assembly 17 is provided on the inner side of the first door body 14.

[0055] In one specific implementation, the bottom surface of the device body 1 has an inclined angle with the horizontal plane.

[0056] like Figure 3 As shown, the temperature-controlled mixing equipment is tilted at a certain angle to the ground, so there is relatively more material on the side closer to the ground, and the heated air will rise. The flow guiding component 17 includes a first flow guiding plate 171 that is inclined towards the end of the bottom surface of the equipment body 1 that is closer to the horizontal plane. The first flow guiding plate 171 can effectively guide the hot air to the lower part of the heating chamber 11 inside the equipment body 1, ensuring that the material in the mixing cylinder 21 is better heated.

[0057] In addition, the flow guiding assembly 17 also includes a second flow guiding plate 172 that is perpendicular to the bottom surface of the device body 1.

[0058] In this embodiment, in addition to the first horizontally inclined guide plate 171, the guide assembly 17 also includes a vertical second guide plate 172. Taking the first door 14 as an example, the second guide plate 172 forms a certain angle with the first door 14, which is equivalent to being inclined towards the mixing cylinder 21 on the outer periphery of the mixing cylinder 21. The second guide plate 172 can effectively guide the hot air to the outer wall of the mixing cylinder 21, thereby improving the heating efficiency.
