The can 11 and the can lid 12 may be detachably and fixedly coupled together by means of a mounting member (e.g., a bolt, a pin, a buckle, etc.), thereby facilitating replacement and maintenance of the internal components. In some embodiments, the can 11 and the can lid 12 may also be non-detachably connected together, improving assembly efficiency. The tank 11 is substantially conical, thereby improving the mixing and drying effect of the material. The radial cross section of the tank 11 in the radial direction Y of the drying tank 10 is gradually reduced in size in the discharging direction.

The material of the stirring shaft 30 includes, but is not limited to, a metal material such as copper, aluminum, or the like, an alloy material such as copper alloy, aluminum alloy, tungsten titanium alloy, or the like, graphene, or the like.

It will be appreciated that during drying of the material, the stirring shaft section 32 is in contact with the material in the drying tank 10, so that the stirring shaft section 32 absorbs heat in the drying chamber 101 and transfers it to the drive shaft section 31, while the mounting fitting 70 is provided outside the drive shaft section 31 to absorb heat of the drive shaft section 31, and both the drive shaft section 31 and the mounting fitting 70 are subject to frictional heat. Therefore, in the embodiment of the present utility model, the cooling structure 80 is disposed on the transmission shaft segment 31, and the cooling structure 80 is used for cooling the mounting accessory 70, so that the probability of the mounting accessory 70 being damaged by high temperature is reduced, and the service life of the mounting accessory 70 is prolonged. The structure of the cooling structure 80 will be described in detail below.

Referring to fig. 1 to 3 together, fig. 3 is an enlarged view of part I of the drying apparatus 100 in fig. 2. Illustratively, in the present embodiment, the cooling structure 80 is configured as a cooling flow channel 810. The drive shaft section 31 is provided with a flow guide groove 3101 along the axial direction X of the drying tank 10. A flow guiding sleeve 82 is arranged in the flow guiding groove 3101, and the flow guiding sleeve 82 and the transmission shaft section 31 form a cooling flow channel 810. The cooling flow channel 810 is used for accommodating a cooling medium, and the cooling medium is used for cooling the mounting fitting 70. The cooling medium may include, but is not limited to, a liquid; or may be a gas. For example, the cooling medium may be water, oil, or the like.

The flow sleeve 82 is rotatably or fixedly arranged relative to the drive shaft segment 31. Illustratively, in the present embodiment, the flow sleeve 82 is disposed on the mounting base 50 and is rotatable relative to the drive shaft segment 31. In this way, the transmission shaft section 31 only drives the stirring shaft section 32 to rotate, so that the stirring shaft section 32 rotates relative to the drying tank 10, stirring of materials is achieved, and the flow guide sleeve 82 is fixed relative to the drying tank 10, so that assembly of the flow guide sleeve 82 is facilitated. Illustratively, in the present embodiment, the flow sleeve 82 is detachably and fixedly coupled to the mounting base 50, thereby facilitating operations such as assembly and replacement of the flow sleeve 82. In some embodiments, the flow sleeve 82 is integrally formed with the mounting base 50, thereby improving the assembly efficiency and connection stability between the flow sleeve 82 and the mounting base 50. In other embodiments, the flow sleeve 82 may be rotatably coupled to the mounting base 50.

In other embodiments, the flow guiding sleeve 82 is disposed on the transmission shaft section 31 and is fixedly disposed relative to the transmission shaft section 31, so that the transmission shaft section 31 drives the stirring shaft section 32 and the flow guiding sleeve 82 to rotate synchronously, thereby avoiding the problem of rotation interference between the flow guiding sleeve 82 and the transmission shaft section 31, and improving the reliability and stability of rotation.

In some embodiments, the mounting accessory 70 is mounted on the side of the transmission shaft section 31 away from the stirring shaft section 32, and the cooling flow channel 810 passes through the mounting accessory 70, so that the heat of the transmission shaft section 31 can be timely dissipated through the cooling medium in the cooling flow channel 810, and further, the problem that the heat of the transmission shaft section 31 is transferred to the mounting accessory 70 to cause abnormal work or damage is avoided, and the service life of the mounting accessory 70 is prolonged. In the axial direction X of the drying tank 10, the height of the tank bottom of the diversion trench 3101 and the end surface of the stirring shaft section 32 close to the transmission shaft section 31 is a first height H1, the height of the mounting fitting 70 and the end surface of the stirring shaft section 32 close to the transmission shaft section 31 is a second height H2, and the first height H1 is smaller than or equal to the second height H2. When the mounting fittings 70 include a plurality of mounting fittings 70, the height of the mounting fittings 70 and the end face of the stirring shaft section 32 near the transmission shaft section 31 refers to the height of the mounting fittings 70 and the end face of the stirring shaft section 32 near the transmission shaft section 31 closest to the stirring shaft section 32. In this way, the high temperature of the transmission shaft section 31 is ensured to be timely dispersed through the cooling medium in the cooling flow channel 810, so that the probability of damage to the mounting accessory 70 by the high temperature is reduced, and the service life of the mounting accessory 70 is prolonged. In some embodiments, at least a portion of the mounting fitting 70 may also be disposed at a location of the propeller shaft segment 31 where the cooling flow channel 810 is not disposed, and disposed proximate to the cooling flow channel 810, the utility model is not limited in particular. The mounting fitting 70 includes, but is not limited to, at least one of a bearing, a seal, and other temperature sensitive elements.

The flow guide sleeve 82 is spaced from the transmission shaft section 31 and coaxially arranged, so that on one hand, the flow channel of the cooling medium in the cooling flow channel 810 is smoother, and on the other hand, the cooling medium is contacted with the flow guide sleeve 82 and the transmission shaft section 31 more uniformly, thereby realizing the effect of uniformly cooling the transmission shaft section 31 and improving the cooling effect. The flow sleeve 82 may also be configured as a thermally conductive structure, so that a portion of the heat of the drive shaft section 31 may also be exhausted through the thermally conductive sleeve, thereby improving the cooling effect of the drive shaft section 31. In some implementations, the flow sleeve 82 may also be configured as a non-thermally conductive structure that transports a thermally conductive medium. The flow sleeve 82 may be spaced from but not coaxially disposed with the drive shaft segment 31; or the flow sleeve 82 at least partially abuts the groove wall of the flow groove 3101 of the drive shaft segment 31.

Referring to fig. 2 and 4 together, fig. 4 is an enlarged view of an embodiment of the drive shaft section 31 and the flow sleeve 82 of the drying apparatus 100 of fig. 2. The diameter of the flow guiding sleeve 82 is larger than the gap between the outer side wall of the flow guiding sleeve 82 and the groove wall of the flow guiding groove 3101, so that the cooling medium can quickly enter the bottom of the flow guiding groove 3101, and the heat dissipation effect of the transmission shaft section 31 is improved. The distance between the end surface of the flow guide sleeve 82, which is close to the stirring shaft section 32, and the groove bottom of the flow guide groove 3101 is a first distance L1, the distance between the outer side wall of the flow guide sleeve 82 and the inner side wall of the transmission shaft section 31 is a second distance L2, and the first distance L1 is greater than the second distance L2, so that the cooling medium flows out of the inner cavity of the flow guide sleeve 82 and diverges to the periphery of the flow guide groove 3101, the impact force of the cooling medium on the groove bottom wall of the flow guide groove 3101 is reduced, and the stirring shaft 30 is prevented from being damaged. In some implementations, a bottom wall of the channel 3101 is provided with a buffer to buffer the impact of the cooling medium against the bottom wall of the channel 3101. Cushioning members include, but are not limited to, sponges.

In some embodiments, the end of the flow sleeve 82 adjacent to the stirring shaft segment 32 is provided with a flow guiding hole 821, so that part of the cooling medium flows out of the flow guiding hole 821, thereby reducing the impact force of the cooling medium on the bottom wall of the flow guiding groove 3101 and preventing the stirring shaft 30 from being damaged. The deflector hole 821 is provided extending in the circumferential direction Z of the deflector sleeve 82. In some embodiments, the flow bore 821 is disposed extending along the axial direction X of the flow sleeve 82. The number of the guide holes 821 may include one or more. Illustratively, in the present embodiment, the number of the flow guide holes 821 includes a plurality of the flow guide holes 821 that are spaced around the circumferential direction Z of the flow sleeve 82. The deflector aperture 821 may be a circular aperture, an elliptical aperture, a square aperture, etc.

Referring again to fig. 1-4, in the present embodiment, the mounting base 50 includes a motor mount 51, for example. The mounting fitting 70 includes a first seal 71 disposed within the motor mount 51. The first seal 71 is sealingly disposed between the inner sidewall of the motor mount 51 and the outer sidewall of the drive shaft segment 31. The first seal 71 forms a discharge chamber 5101 with the motor mount 51 and the drive shaft segment 31. The cooling flow passage 810 includes a first flow passage 811 and a second flow passage 812 communicating with the first flow passage 811. One end of the first flow passage 811 facing away from the second flow passage 812 is connected to an external cooling device, and one end of the second flow passage 812 facing away from the first flow passage 811 is communicated with the discharge chamber 5101.

An external cooling device is used to provide a cooling medium to the cooling flow channels 810. External cooling devices may include, but are not limited to, transfer pumps, pressure transfer devices, gravity transfer devices, and the like. Illustratively, in the present embodiment, the first flow passage 811 is disposed within the flow sleeve 82, and the second flow passage 812 is disposed between the flow sleeve 82 and the drive shaft section 31, so that, on the one hand, the cooling medium can quickly enter the first flow passage 811 and flow toward the end of the second flow passage 812 near the stirring shaft section 32, reducing the flow resistance of the cooling medium; on the other hand, since the temperature of the end of the driving shaft section 31 close to the stirring shaft section 32 is higher than the temperature of the end of the driving shaft section 31 far away from the stirring shaft section 32, the cooling medium can timely take away the temperature of the end of the driving shaft section 31 close to the stirring shaft section 32, and the cooling effect of the driving shaft section 31 is improved. In some embodiments, a first flow passage 811 may also be provided between the flow sleeve 82 and the drive shaft segment 31, and a second flow passage 812 may also be provided within the flow sleeve 82.

The air guide sleeve 82 is fixed to the motor housing 51. Specifically, the air guide sleeve 82 is fixed to the top wall of the motor housing 51. The guide sleeve penetrates through the top wall of the motor base 51 and is communicated with external cooling equipment. The flow sleeve 82 is in sealing connection with the motor base 51 through the sealing sleeve 72. The motor housing 51 has a through hole 5104 formed in the top wall thereof. The sealing sleeve 72 is sleeved on the outer wall of the flow guiding sleeve 82 and is in interference fit with the hole wall of the through hole 5104. The sealing sleeve 72 is provided with a stop flange 721 which stops against the top wall of the motor housing 51. The limiting flange 721 is used to limit the depth of insertion of the flow sleeve 82 into the flow groove 3101, so that the flow sleeve 82 is suspended relative to the transmission shaft section 31 of the stirring shaft 30, thereby improving the smoothness of the flow of the cooling medium from the first flow channel 811 to the second flow channel 812.

Referring to fig. 1 to 4 together, when the drying apparatus 100 is used, the cooling medium sequentially passes through the first flow passage 811, the second flow passage 812 and the discharge chamber 5101 and is discharged through the discharge pipe 5103, wherein the dashed arrow in fig. 3 indicates the flow direction of the cooling medium. The temperature of the cooling medium is lower than that of the transmission shaft section 31, so that the cooling medium can absorb heat of the transmission shaft section 31 and discharge the heat out of the drying equipment 100, thereby avoiding the problem that the high temperature of the stirring shaft section 32 is abnormally operated or damaged due to heat transfer to the mounting accessory 70 through the transmission shaft section 31, improving the working efficiency of the drying equipment 100 and prolonging the service life of the drying equipment 100. In addition, the stirring shaft section 32 is not provided with the cooling structure 80, so that the temperature in the tank 11 is reduced and taken away by the stirring shaft section 32, and the processing quality of materials is improved.

Referring to fig. 2 and 5 together, fig. 5 is an enlarged view of another embodiment of the drive shaft section 31 and the flow sleeve 82 of the drying apparatus 100 of fig. 2. The cooling structure 80 is configured as a phase change heat storage structure 820. The drive shaft segment 31 is provided with a receiving cavity 3102 receiving the phase change heat storage structure 820. Illustratively, in this embodiment, the housing cavity 3102 is configured as a sealed cavity that prevents the phase change heat storage structure 820 from flowing out of the housing cavity 3102. For example, the drive shaft section 31 is provided with a guide groove 3101 along the axial direction X of the drying tank 10, and the top of the guide groove 3101 is provided with a blocking structure for sealing the notch of the guide groove 3101, so that the sealing structure and the drive shaft section 31 form a housing cavity 3102. The sealing structure and the transmission shaft section 31 can be detachably connected together in a threaded connection, a clamping connection and the like, so that the phase change heat storage structure 820 can be conveniently assembled and replaced. The sealing structure and the transmission shaft segment 31 can also be non-detachably connected together by welding, bonding or the like. In some embodiments, the receiving cavity 3102 may also be configured as a semi-open cavity, thereby facilitating assembly and replacement of the phase change heat storage structure 820. The material of the phase-change heat storage structure 820 may be solid-liquid phase-change material such as paraffin, or solid-solid phase-change material such as copper-aluminum-nickel alloy, which is not limited in particular.

Referring to fig. 2 and 5 together, when the drying apparatus 100 is used, the stirring shaft section 32 contacts the material in the drying tank 10, so that the stirring shaft section 32 absorbs heat in the drying chamber 101 and transfers the heat to the driving shaft section 31, the mounting fitting 70 is disposed outside the driving shaft section 31 to absorb heat of the driving shaft section 31, and both the driving shaft section 31 and the mounting fitting 70 are prone to generate heat by friction. The phase-change heat storage structure 820 arranged on the transmission shaft section 31 can perform phase change and absorb the heat, and takes away the heat of the transmission shaft section 31 to cool the transmission shaft section 31, so that the heat of the transmission shaft section 31 is prevented from being transmitted to the mounting accessory 70, the probability of the mounting accessory 70 being damaged by high temperature is reduced, and the service life of the mounting accessory 70 is prolonged.
