Description

Technical Field

[0001] This utility model relates to the field of recycling device technology, and in particular to a mobile, non-sticky BDO material heating and recycling device. Background Technology

[0002] In BDO production, the low temperatures of winter cause an exponential increase in material viscosity, becoming a core bottleneck restricting the stable operation of the equipment. BDO is extremely sensitive to temperature; as ambient temperature drops, molecular motion slows significantly, intermolecular forces increase sharply, and the material almost completely loses its fluidity, even exhibiting semi-solid characteristics, greatly increasing the difficulty of recycling. While existing recycling equipment can heat the material to reduce viscosity, it suffers from significant deficiencies in heating uniformity. Current heating methods mostly employ direct contact heating, where the heating elements are in direct contact with the material. This easily leads to material adhesion and scaling; furthermore, uneven heat dissipation easily causes localized overheating and underheating, greatly affecting the viscosity reduction effect. Summary of the Invention

[0003] The technical problem to be solved by this utility model is that the existing heating methods mostly adopt direct contact heating, where the heating components are in direct contact with the material. On the one hand, this easily leads to the adhesion and scaling of the material. On the other hand, the heat is unevenly distributed, which easily causes local overheating and underheating to coexist. To address this, we propose a portable, non-stick BDO material heating and recovery device.

[0004] To achieve the above objectives, this application adopts the following technical solution: a movable, non-stick BDO material heating and recovery device, comprising a recovery tank and a protective frame fixedly connected to the outer wall of the recovery tank. A lower connecting plate is fixedly connected to the lower wall of the protective frame, and a caster wheel is installed at the lower end of the lower connecting plate. A heating component is provided on the outer wall of the recovery tank. The heating component includes an air inlet pipe penetrating through the outer wall of the recovery tank. An external connecting pipe is fixedly connected to the end of the air inlet pipe away from the recovery tank, and a heating steam coil is connected to the end of the air inlet pipe away from the external connecting pipe. A heat-conducting layer is attached to the outer wall of the heating steam coil.

[0005] Furthermore, multiple sets of heating steam coils are provided, and all sets of heating steam coils are evenly distributed around the inner wall of the recovery tank.

[0006] Furthermore, the heat-conducting layer is a component made of ceramic material.

[0007] Furthermore, the upper end of the recycling tank is provided with a feeding channel, the inner wall of the feeding channel is provided with a sliding rod, and the lower end of the sliding rod is fixedly connected to a partition body. The partition body has a conical structure, and the bottom of the partition body matches the inner diameter of the feeding channel.

[0008] Furthermore, a chute body is provided on both sides of the inner wall of the feeding channel. A slider body is slidably connected to the inner wall of the chute body. The slider body is fixedly connected to the sliding rod. An inner rod body is fixedly connected to the lower wall of the slider body. An outer rod body is provided at the lower end of the inner rod body. The inner rod body and the inner wall of the outer rod body are slidably connected. The lower wall of the outer rod body is fixedly connected to the bottom of the cavity of the chute body.

[0009] Furthermore, a support spring is fitted on the outer wall of the inner rod body, the upper wall of the support spring is fixedly connected to the slider body, and the lower wall of the support spring is fixedly connected to the upper wall of the outer rod body.

[0010] The technical effects and advantages of this utility model are as follows:

[0011] In this invention, an external steam source is connected to an external pipe. Steam is introduced into the external pipe and then into a heating steam coil. The steam flows within the heating steam coil, transferring heat to the material through the coil wall. The heat-conducting layer, made of nano-ceramic coating, greatly reduces the adhesion between the material and the coil due to its nanoscale ultra-smooth surface, fundamentally avoiding the problem of material adhesion and scaling. At the same time, the high thermal conductivity of the nano-ceramic coating, combined with the uniformly coiled heating steam coil, can quickly and evenly transfer heat to the material, avoiding local overheating or underheating, effectively improving the material viscosity reduction effect, and ensuring that the BDO material maintains good fluidity throughout the recycling process. This solves the problem that existing heating methods mostly use direct contact heating, where the heating element is in direct contact with the material. On the one hand, this easily leads to material adhesion and scaling; on the other hand, uneven heat dissipation easily causes local overheating and underheating, greatly affecting the viscosity reduction effect.

Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0020] Reference Figures 1-5 To address the problems of existing heating methods that mostly employ direct contact heating, where the heating element is in direct contact with the material, which easily leads to material adhesion and scaling, and uneven heat dissipation, resulting in both localized overheating and underheating, significantly impacting the viscosity reduction effect, the following preferred technical solution is provided:

[0021] A portable, non-stick BDO material heating and recovery device includes a recovery tank 1, which serves as the core container for storing BDO material. A protective frame 2 is fixedly connected to the outer wall of the tank. The protective frame 2 not only protects the recovery tank but also enhances the overall structural strength of the device. A caster wheel 4 is installed at the lower end of a lower plate 3 fixed to the lower wall of the protective frame 2, enabling the device to move flexibly and easily to different material recovery points. The heating assembly 5 is a key component of the device, including an air inlet pipe 51, an external pipe 52, heating steam coils 53, and a heat-conducting layer 54. The air inlet pipe 51 penetrates the outer wall of the recovery tank 1, with one end connected to the external pipe 52 for accessing an external steam source, and the other end connected to the heating steam coils 53. Multiple sets of heating steam coils 53 are evenly coiled around the inner wall of the recovery tank 1 to maximize the contact area with the material. A heat-conducting layer 54 made of a nano-ceramic coating is adhered to the outer wall of the coils. This nano-ceramic coating has high thermal conductivity, an ultra-smooth surface, and excellent chemical stability.

[0022] The upper end of the recycling tank 1 is provided with a feeding channel 6. The inner wall of the feeding channel 6 is provided with a sliding rod 7. The lower end of the sliding rod 7 is fixedly connected to a partition body 8. The partition body 8 has a conical structure. The bottom of the partition body 8 matches the inner diameter of the feeding channel. Both sides of the inner wall of the feeding channel 6 are provided with a groove body. The inner wall of the groove body is slidably connected to a slider body 9. The slider body 9 is fixedly connected to the sliding rod 7. The lower wall of the slider body 9 is fixedly connected to an inner rod body 10. The lower end of the inner rod body 10 is provided with an outer rod body 11. The inner rod body 10 and the inner wall of the outer rod body 11 are slidably connected. The lower wall of the outer rod body 11 is fixedly connected to the bottom of the cavity of the groove body. The outer wall of the inner rod body 10 is fitted with a support spring 12. The upper wall of the support spring 12 is fixedly connected to the slider body 9. The lower wall of the support spring 12 is fixedly connected to the upper wall of the outer rod body 11.

[0023] Specifically, when heating the material in the tank, an external steam source is connected to the external pipe 52. Steam is introduced into the external pipe 52 and then into the heating steam coil 53. The steam flows within the heating steam coil 53, transferring heat to the material through the coil wall. The heat-conducting layer 54, made of nano-ceramic coating, greatly reduces the adhesion between the material and the coil due to its nano-level ultra-smooth surface, fundamentally avoiding the problem of material adhesion and scaling. At the same time, the high thermal conductivity of the nano-ceramic coating, combined with the uniformly coiled heating steam coil 53, can quickly and evenly transfer heat to the material, avoiding local overheating or underheating, effectively improving the material viscosity reduction effect, and ensuring that the BDO material maintains good fluidity throughout the recycling process. This solves the problem that existing heating methods mostly use direct contact heating, where the heating components are in direct contact with the material. On the one hand, this easily leads to material adhesion and scaling; on the other hand, uneven heat dissipation easily causes local overheating and underheating, greatly affecting the viscosity reduction effect.

[0024] When no material enters, the partition block 8, under the combined action of its own weight and the elastic force of the support spring 12, tightly adheres to the bottom of the feed channel, forming an effective seal to prevent heat loss and material vapor from escaping from the tank. As BDO material continues to accumulate on the upper surface of the partition block 8, the weight of the material gradually exceeds the elastic force of the support spring 12, pushing the partition block 8 down along the slide body, causing the sliding rod 7 and the slider body 9 to descend synchronously. The inner rod body 10 stretches the spring and slides within the outer rod body 11. At this time, the conical structure of the partition block 8 is exposed, disengaging from the sealed position at the bottom of the feed channel. The accumulated material can slide naturally into the recovery tank by gravity along the inclined angle of the conical surface, achieving unobstructed feeding. When the material is transported, the support spring 12 releases its elastic potential energy, pushing the partition block 8 upward to reset and reseal the feed channel. This ensures the sealing and controllability of the feeding process and effectively reduces the entry of cold air from the outside, maintaining a stable temperature of the material inside the tank.

[0025] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
