[0017] To facilitate the understanding of the present invention, the present invention will be described more comprehensively below with reference to the relevant drawings. The preferred embodiments of the present invention are shown in the drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, these embodiments are provided to make the understanding of the disclosure of the present invention more thorough and comprehensive.

[0018] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly on the other element or there may also be an intermediate element. When an element is considered to be "connected" to another element, it can be directly connected to the other element or there may be an intermediate element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only.

[0019] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the technical field to which this invention belongs. The terms used in the description of the present invention herein are for the purpose of describing specific embodiments only and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0020] Combined with Figures 1 to 15 As shown, schematically shown is a paraffin treatment device for building thermal insulation materials of the present invention, including a heat absorption device 30, a heat release device 40, a first stirring cylinder 10, and a second stirring cylinder 20.

[0021] As Figure 2 , both the first stirring cylinder 10 and the second stirring cylinder 20 are cylindrical structures. The difference is that the first stirring cylinder 10 has a first head end 11 and a first tail end 12, the first head end 11 and the first tail end 12 are through, the first head end 11 has a feed port 111, and the first tail end 12 has a material passing port 121. The second stirring cylinder 20 has a second head end 21 and a second tail end 22. Among them, the second head end 21 has a discharge port 211, and the second tail end 22 is closed. The radius of the first stirring cylinder 10 is smaller than the radius of the second stirring cylinder 20. The first stirring cylinder 10 is located inside the second stirring cylinder 20 and the two are rotationally connected. The rotation directions of the first stirring cylinder 10 and the second stirring cylinder 20 are opposite. The material passing port 121 of the first stirring cylinder 10 is disposed opposite to the inner end face of the second tail end 22 of the second stirring cylinder 20. The material in the first stirring cylinder 10 can enter the second tail end 22 of the second stirring cylinder 20 through the material passing port 121. As Figure 1 , the feed port 111 and the discharge port 211 are adjacent to each other, which is beneficial to the layout of the material conveying pipelines around the device.

[0022] As Figure 2 and Figure 6 , the heat release device 40 is located inside the first stirring cylinder 10, and the heat absorption device 30 is located between the first stirring cylinder 10 and the second stirring cylinder 20. The heat release device 40 is used to release heat and heat the material inside the first stirring cylinder 10, and the heat absorption device 30 is used to absorb heat and cool the material between the second stirring cylinder 20 and the first stirring cylinder 10.

[0023] The feed port 111 of the first stirring cylinder 10 is used to input aggregates (such as sand and gravel) and paraffin in a solid-liquid mixed state. The paraffin in the solid-liquid mixed state has a certain fluidity. Therefore, the aggregates and the paraffin in the solid-liquid mixed state can slowly flow to the first tail end 12 of the first stirring cylinder 10 under the rotation and stirring of the first stirring cylinder 10. During this process, the heat release device 40 can continuously heat the paraffin in the solid-liquid mixed state inside the first stirring cylinder 10, so that the paraffin in the solid-liquid mixed state is heated and transformed into liquid paraffin. With the stirring of the first stirring cylinder 10, the liquid paraffin can also be fully stirred and mixed with the aggregates.

[0024] As Figure 15 , the mixture composed of liquid paraffin and aggregate enters the second tail end 22 of the second mixing drum 20 from the material passing port 121 of the first mixing drum 10, and gradually moves to the second head end 21 of the second mixing drum 20 as the second mixing drum 20 rotates and stirs. During this process, the heat absorption device 30 absorbs the heat of the mixture to lower the temperature of the mixture, but the liquid paraffin remains in a liquid state to ensure its fluidity, which makes the temperature of the mixture discharged from the discharge port 211 more controllable. The mixture discharged from the discharge port 211 is poured into the wall interlayer, so that the temperature of the paraffin aggregate mixture in the wall interlayer can be controlled. After the paraffin aggregate mixture solidifies, the density of the paraffin aggregate mixture in the wall interlayer is uniform and the heat insulation performance is better.

[0025] The first mixing drum 10, the second mixing drum 20, the heat release device 40 and the heat absorption device 30 of the equipment can continuously process the solid-liquid mixed paraffin and aggregate, and produce a liquid paraffin and aggregate mixture with a stable temperature, which is beneficial to improving the heat insulation performance and structural strength of the building heat insulation wall. In addition, the movement direction of the mixture composed of liquid paraffin and aggregate in the equipment is first from the first head end 11 to the first tail end 12, and then from the second tail end 22 to the second head end 21, and the front and back movement directions are opposite, which can achieve a longer processing stroke of the mixture in a limited structural space, the stirring is more uniform, and the discharge temperature of the discharge port 211 is also more stable.

[0026] More specifically, the heat release device 40 can be provided with heating wires, and when the heating wires are energized, heat can be generated and used to heat the solid-liquid mixed paraffin in the first mixing drum 10. In order to save energy, the paraffin treatment equipment for building heat insulation materials of the present invention further includes a compressor and a throttling device. A heat release flow channel 41 is provided in the heat release device 40, and a heat absorption flow channel 31 is provided in the heat absorption device 30; the compressor, the heat release flow channel 41, the throttling device and the heat absorption flow channel 31 are sequentially connected in a cycle. A heat conduction medium is filled in the heat absorption flow channel 31 and the heat release flow channel 41, and the heat conduction medium circulates through the compressor, the heat release flow channel 41, the throttling device and the heat absorption flow channel 31, so as to realize the heat release of the heat conduction medium in the heat release flow channel 41 and the heat absorption in the heat absorption flow channel 31, and realize the transfer of heat energy. Through the setting of the compressor, the heat release flow channel 41, the throttling device and the heat absorption flow channel 31, the energy consumption of the heating wires in the heat release device 40 can be reduced.

[0027] Combined with Figures 3 to 5As shown, in this embodiment, the heat release device 40 is in a cylindrical structure, which is coaxially arranged with the first mixing drum 10 and the two can rotate relative to each other. The building insulation material paraffin treatment device further has a base 50. The second mixing drum 20 and the first mixing drum 10 are respectively rotatably connected to the base 50. The heat release device 40 is connected to the base 50, and the heat release device 40 is relatively fixed to the base 50 and the two cannot rotate relative to each other. The heat absorption device 30 is in a cylindrical shape and is coaxially arranged with the second mixing drum 20. The heat absorption device 30 is connected to the base 50, and the heat absorption device 30 is relatively fixed to the base 50 and the two cannot rotate relative to each other; a plurality of material passing groove holes 32 are arranged along the axial direction of the heat absorption device 30. Since the heat absorption device 30 is located between the first mixing drum 10 and the second mixing drum 20, when the mixture at the second tail end 22 flows towards the second head end 21, there are two spaces for the mixture to flow. One is the space between the outer wall surface of the first mixing drum 10 and the inner wall surface of the heat absorption device 30, and the other is the space between the outer wall surface of the heat absorption device 30 and the inner wall surface of the second mixing drum 20. In order to mix and stir the mixture in these two spaces, the above-mentioned material passing groove holes 32 are opened on the heat absorption device 30, and the material passing groove holes 32 communicate the outer wall surface and the inner wall surface of the heat absorption device 30.

[0028] Further, as Figure 4 and Figure 5 , the inner wall surface of the first mixing drum 10 is provided with a first mixing component 13 opposite to the heat release device 40. The first mixing component 13 is spirally arranged along the axial direction of the first mixing drum 10. In other words, the first mixing component 13 is in a spiral shape. When the first mixing drum 10 rotates, the spiral first mixing component 13 drives the mixture in the first mixing drum 10 to move from the first head end 11 to the first tail end 12, and at the same time forces the mixture to slide on the surface of the heat release device 40 and absorb heat. The inner wall surface of the second mixing drum 20 is provided with a second mixing component 23 opposite to the heat absorption device 30. The second mixing component 23 is spirally arranged along the axial direction of the second mixing drum 20. Similarly, the second mixing component 23 is in a spiral shape. When the second mixing drum 20 rotates, the spiral second mixing component 23 drives the mixture between the first mixing drum 10 and the second mixing drum 20 to move from the second tail end 22 to the second head end 21, and forces the mixture to slide on the surface of the heat absorption device 30 and absorb heat. The rotation directions of the first mixing drum 10 and the second mixing drum 20 are opposite, and the spiral directions of the first mixing component 13 and the second mixing component 23 are the same, which makes the directions of the first mixing component 13 and the second mixing component 23 driving the mixture opposite.

[0029] In addition, a third stirring member 14 is provided on the outer wall surface of the first mixing drum 10 and is disposed opposite to the heat absorption device 30. The third stirring member 14 and the first stirring member 13 are disposed back to back. The third stirring member 14 is spirally arranged along the axial direction of the first mixing drum 10. The third stirring member 14 is spiral. When the first mixing drum 10 rotates, the spiral third stirring member 14 drives the mixture between the first mixing drum 10 and the second mixing drum 20 to move from the second tail end 22 to the second head end 21. Further, the second stirring member 23 and the third stirring member 14 jointly drive the mixture between the first mixing drum 10 and the second mixing drum 20 to move from the second tail end 22 to the second head end 21. The spiral directions of the third stirring member 14 and the first stirring member 13 are opposite. When the rotation directions of the first mixing drum 10 and the second mixing drum 20 are opposite, the directions of the third stirring member 14 and the second stirring member 23 for driving the mixture are the same.

[0030] The third stirring member 14 is located in the space between the outer wall surface of the first mixing drum 10 and the inner wall surface of the heat absorption device 30. The second stirring member 23 is located in the space between the outer wall surface of the heat absorption device 30 and the inner wall surface of the second mixing drum 20. The arrangement of the second stirring member 23 and the third stirring member 14 is also beneficial to forcing the mixtures in the above two spaces to be further mixed and stirred with each other.

[0031] In this embodiment, as shown in Figures 8 to 12 shown, the rotation speed of the first mixing drum 10 relative to the base 50 is greater than the rotation speed of the second mixing drum 20 relative to the base 50. One reason is that the volume inside the first mixing drum 10 is smaller than the volume of the space between the second mixing drum 20 and the first mixing drum 10. A greater rotation speed of the first mixing drum 10 can input more mixture to match the volume of the space between the second mixing drum 20 and the first mixing drum 10. Another reason is that the conveying speeds of the second stirring member 23 and the third stirring member 14 for the mixture can be made inconsistent. More specifically, the pitches of the second stirring member 23 and the third stirring member 14 are the same, and the conveying speed of the third stirring member 14 for the mixture is greater than the conveying speed of the second stirring member 23 for the mixture. The advantage is that on the premise that the second stirring member 23 and the third stirring member 14 jointly convey the mixture from the second tail end 22 to the second head end 21, there is a difference in the conveying speeds of the second stirring member 23 and the third stirring member 14, which can force the mixture between the first mixing drum 10 and the second mixing drum 20 to roll under the stirring of the second stirring member 23 and the third stirring member 14, and the rolling mixture can pass through the material passing groove hole 32.

[0032] To drive the first mixing drum 10 and the second mixing drum 20 to rotate, the paraffin treatment device for building thermal insulation materials further includes a first transmission belt 60, a second transmission belt 70, and a drive shaft 51 rotatably connected to the base 50.

[0033] AsFigure 11 and Figure 12 , a drive sleeve 15 arranged coaxially with the first end 12 of the first mixing drum 10 is provided at the first end 12 of the first mixing drum 10. The drive sleeve 15 communicates with the interior of the first mixing drum 10, and the end of the heat release device 40 rotatably penetrates through the drive sleeve 15. An assembly hole 26 and a second driven pulley 27 arranged around the assembly hole 26 are provided at the second end 22 of the second mixing drum 20. The drive sleeve 15 rotatably penetrates through the assembly hole 26, and a first driven pulley 151 is provided on the part of the drive sleeve 15 outside the assembly hole 26. A first transmission belt 60 is wound around the drive shaft 51 and the first driven pulley 151, and a second transmission belt 70 is wound around the drive shaft 51 and the second driven pulley 27. The drive shaft 51 can be driven by an existing electric motor. The drive shaft 51 drives the first driven pulley 151 and the second driven pulley 27 to rotate respectively through the first transmission belt 60 and the second transmission belt 70, so as to drive the first mixing drum 10 and the second mixing drum 20 to rotate. More specifically, the inner side of the first transmission belt 60 is wound around the drive shaft 51 and the first driven pulley 151, the inner side of the second transmission belt 70 is wound around the second driven pulley 27, and the outer side of the second transmission belt 70 is wound around the drive shaft 51, so that one drive shaft 51 can drive the first mixing drum 10 and the second mixing drum 20 to rotate in opposite directions at the same time. The radius of the second driven pulley 27 is greater than the radius of the first driven pulley 151, so that the rotation speed of the first mixing drum 10 is greater than the rotation speed of the second mixing drum 20.

[0034] In order to make the process of the mixture flowing into the second end 22 at the material passing opening 121 and turning to flow to the second head end 21 smoother, a flow guiding groove 24 is provided on the inner end surface of the second end 22 of the second mixing drum 20. The flow guiding groove 24 is annular. The projection of the material passing opening 121 on the groove bottom surface of the flow guiding groove 24 is located in the middle of the flow guiding groove 24. A flow guiding conical surface 25 is provided on one side of the flow guiding groove 24. The generatrix of the flow guiding conical surface 25 is inclined with respect to the axis of the second mixing drum 20. The mixture flowing into the second mixing drum 20 at the material passing opening 121 first impacts on the flow guiding conical surface 25. The flow guiding conical surface 25 forces the mixture to turn and flow into the flow guiding groove 24. The cross section of the flow guiding groove 24 is trapezoidal in reverse. Such a structure can force the mixture to gradually turn to flow towards the second head end 21.

[0035] As Figure 7 and Figure 8, the paraffin treatment equipment for building thermal insulation materials further includes a material guiding device 80. The material guiding device 80 is provided with a feed pipe opening 81 and a discharge cavity 83 arranged around the feed pipe opening 81. A discharge pipe opening 82 communicating with the discharge cavity 83 is formed on the material guiding device 80. The feed pipe opening 81 can be connected to an existing heating barrel through a flange. The heating barrel can heat a large amount of solid paraffin to a solid-liquid mixture state. The discharge pipe opening 82 can be connected to a conveying pipe through a flange. Construction workers can place the conveying pipe in the wall interlayer to pour the liquid paraffin and aggregate mixture; the material guiding device 80 is respectively rotatably connected to the first stirring cylinder 10 and the second stirring cylinder 20. The feed pipe opening 81 communicates with the feed port 111, and the discharge cavity 83 communicates with the discharge port 211.

[0036] In some alternative embodiments, a housing 90 is detachably provided on the base 50. It can be seen that Figure 13 and Figure 14 , the second stirring cylinder 20 is located inside the housing 90, and the housing 90 can be used to protect the second stirring cylinder 20.

[0037] In summary, the radius of the first stirring cylinder 10 is smaller than that of the second stirring cylinder 20. The first stirring cylinder 10 is located inside the second stirring cylinder 20 and the two are rotatably connected. The rotation directions of the first stirring cylinder 10 and the second stirring cylinder 20 are opposite, so as to realize the long-distance transportation of paraffin with a smaller equipment volume, and the paraffin can have a longer processing distance inside the equipment; one end of the first stirring cylinder 10 is provided with a feed port 111 for injecting the solid-liquid mixture of paraffin and aggregate, and the other end is provided with a material passing port 121 communicating with the second stirring cylinder 20. The end of the second stirring cylinder 20 is provided with a discharge port 211 adjacent to the feed port 111. The heat release device 40 is located inside the first stirring cylinder 10, and the heat absorption device 30 is located between the first stirring cylinder 10 and the second stirring cylinder 20; as the first stirring cylinder 10 rotates and stirs, the solid-liquid mixture of paraffin is heated by the heat release device 40 and becomes liquid. The liquid paraffin enters the second stirring cylinder 20 through the material passing port 121 for continuous stirring. The heat absorption device 30 between the second stirring cylinder 20 and the first stirring cylinder 10 absorbs the heat of the liquid paraffin and cools the paraffin, so that the temperature of the liquid paraffin discharged from the discharge port 211 is lower and it cools and solidifies faster to reduce the construction working hours of the thermal insulation wall, and the equipment can continuously process and output liquid paraffin.

[0038] The above are only the embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. All equivalent structural or equivalent process transformations made by using the content of the specification and drawings of the present invention, or directly or indirectly applied to other related technical fields, are equally included in the patent protection scope of the present invention.
