Description

Technical Field

[0001] This invention relates to the field of resin material pretreatment, and more specifically to a resin heating furnace. Background Technology

[0002] Heating resin in tonnes is a crucial process in industrial production for the storage and transportation of viscous resinous liquids. Resin materials are classified into thermosetting and thermoplastic types based on their molecular chain structure. Thermoplastic resins (such as PEEK and polyurethane) can be melted and flowed by heating, facilitating subsequent processing or transportation, while thermosetting resins cannot be remelted after curing. In tonne storage scenarios, low temperatures can easily cause resin viscosity to increase or even solidify, affecting unloading efficiency; therefore, heating is necessary to reduce viscosity.

[0003] The heating process requires strict control of the heating intensity. When the existing heating device heats the resin in the ton container, the heating intensity distribution is often uneven, which causes the resin to overheat in some areas and fail due to its own properties, which has a great impact on the subsequent use of the resin.

[0004] Therefore, a resin heating furnace is needed to solve the above-mentioned technical problems. Summary of the Invention

[0005] To achieve the above objectives, the present invention provides the following technical solution: a resin heating furnace, comprising: an outer shell, an observation box, an opening and closing door, a ton barrel mechanism, a drive mechanism, and a heating mechanism;

[0009] Furthermore, as a preferred embodiment, the drive mechanism includes: a drive component, a main bevel gear, a secondary bevel gear, a stabilizer, a rotating rod, a threaded portion, and a guide frame; The driving component is located at the center of the top of the outer shell. The output shaft of the driving component rotates through the outer shell and extends into the heating zone. The main bevel gear is connected to one end of the output shaft of the driving component located in the heating zone. Multiple stabilizing frames are arranged around the top circumference inside the outer shell. Each stabilizing frame is rotatably equipped with a rotating rod. One end of each rotating rod is rotatably connected to the side wall of the outer shell, and the other end is meshed with the main bevel gear through the secondary bevel gear. The outer wall of the end of each rotating rod near the side wall of the outer shell is provided with a threaded portion. The guide frame is arranged in a grid shape and is mounted between the inner walls of the outer shell via the stabilizing frame. The guide frame is located on the side of the plurality of rotating rods near the top of the outer shell.

[0010] Furthermore, as a preferred embodiment, the guide frame has a heat inlet on the outer wall of the heating zone near the ton barrel mechanism, and the guide frame has a heat dissipation outlet on the outer wall of the heat dissipation cavity.

[0011] Furthermore, preferably, the heating mechanism includes: a movable plate, a heating tape, and a sliding sleeve; The movable plate is connected to the threaded part through the sliding sleeve. Multiple heat tracing tapes are evenly arranged on the side of the movable plate away from the inner wall of the outer shell. The movable plate is slidably connected to the outer wall of the guide frame.

[0012] Furthermore, as a preferred embodiment, the control mechanism includes: a control housing, a trigger rod, a blade, a receiving port, a connecting frame, and a control assembly; The control housing is located at the top of the inside of the ton barrel. The end of the main bevel gear away from the drive component is connected to the trigger rod. The end of the trigger rod away from the main bevel gear rotates through the control housing and is circumferentially arranged with multiple blades. The control housing has multiple receiving ports around its circumference, and the multiple receiving ports form a group of receiving ports. The multiple receiving ports are equidistantly arranged along the axis of the control housing. Each receiving port is provided with a connecting frame, and each connecting frame is provided with a control component. Each connecting frame is rotatably connected to the trigger rod.

[0013] Furthermore, as a preferred embodiment, the control component includes: a sliding column, a rocker arm, a trigger block, and a trigger spring; The sliding column is slidably connected to the connecting frame. One end of the sliding column is rotatably provided with a symmetrical swing rod, and the other end is provided with a trigger block.

[0014] Furthermore, preferably, the trigger rod includes a protrusion and a recess; The trigger rod has multiple trigger groups equidistantly arranged on its outer wall along its axial direction.

[0015] Furthermore, as a preferred embodiment, the control mechanism further includes: a guide wheel; The guide wheel is rotatably mounted on the control housing at the receiving opening position, and the guide wheel abuts against the swing arm.

[0016] Compared with the prior art, the present invention provides a resin heating furnace, which has the following beneficial effects: Advantage 1: This application enables the preheating and subsequent enhanced heating of resin within the container, providing gradient heating to the resin. Simultaneously, the two swing arms exert alternating outward and inward clamping movements on the resin, collectively creating a disturbance. This disturbance occurs in two phases: the first occurs when the heating mechanism enhances the resin's heating, and the second occurs when the heating mechanism resets and waits for the resin to dissipate heat. These two identical disturbances serve different purposes: preventing localized overheating during the enhanced heating process and improving the resin's heat dissipation efficiency before use, thus saving time spent waiting for the resin to cool down.

[0017] Advantage 2: This application features a heat dissipation cavity that efficiently dissipates residual heat during the resin heating process, preventing heat damage to personnel and the equipment itself. Specifically: Excess heat generated in the heating zone during heating, along with a small amount of gas volatilized during resin heating, flows into the guide frame through the heat inlet and then into the heat dissipation cavity through the heat dissipation outlet. Heat flows along the cavity, exchanging heat with the outer wall of the outer casing. Some heat is naturally dissipated through the outer wall of the outer casing, while the remaining heat and gas are discharged through the heat dissipation cavity.

[0018] Advantage 3: Compared with traditional heating methods, the heating cable used in this application features precise temperature control and rapid thermal response, allowing for adjustment of heating power according to actual needs and avoiding energy waste. Furthermore, the heating cable does not produce combustion exhaust gases, making it environmentally friendly and meeting the environmental protection requirements of modern industry. For media requiring the maintenance of a specific temperature, the heating cable can compensate for heat loss, keeping the medium temperature within the set range.

[0019] Advantage 4: This application features a fire blanket on the exterior of the outer casing. The fire blanket is woven from non-combustible fibers and, when placed over a fire source, effectively blocks contact between air and flames. The fire blanket itself is non-combustible and forms a physical barrier, preventing the flames from spreading to surrounding flammable materials, effectively preventing the fire from escalating, buying time for evacuation and subsequent rescue, and ensuring personnel safety.

[0021] Please see Figures 1-8 The present invention provides a resin heating furnace, comprising: an outer shell 1, an observation box 2, an opening and closing door 3, a ton barrel mechanism 4, a drive mechanism 5, and a heating mechanism 6; Among them, an observation box 2 is provided on one side of the outer shell 1, an opening and closing door 3 is provided on the observation box 2, a ton barrel mechanism 4 is provided in the center of the outer shell 1, a drive mechanism 5 is provided on the outer shell 1, and multiple heating mechanisms 6 are arranged around the inner circumference of the outer shell 1. One side wall of the outer shell 1 is detachable, and the observation box 2 is connected to this side wall. The observation box 2 is hollow. A heating zone is formed between the outer shell 1 and the ton barrel mechanism 4.

[0022] In this embodiment, please refer to Figure 1 As shown, the outer shell 1 is made of high-temperature resistant stainless steel, and the observation box 2 is made of the same stainless steel as the outer shell 1. A ton container mechanism 4 is coaxially arranged at the center of the inner shell 1. The ton container mechanism 4 is used to hold the resin to be heated. A drive mechanism 5 is fixedly arranged at the center of the top of the outer shell 1. The drive mechanism 5 provides power to drive the heating mechanism 6. Multiple heating mechanisms 6 are evenly distributed along the circumference inside the outer shell 1. The heating mechanisms 6 generate heat. A heating zone is formed between the inner wall of the outer shell 1 and the outer wall of the ton container mechanism 4. The heating mechanisms 6 are located within this heating zone, ensuring that the heat is concentrated on the ton container mechanism 4.

[0023] Furthermore, heat dissipation cavities 11 are provided in the side walls of the outer casing 1.

[0024] In this embodiment, the heat dissipation cavity 11 has a rectangular cross-section and is manufactured using an integral molding process, which is synchronously processed with the side wall of the outer shell 1 to ensure the airtightness of the heat dissipation cavity 11 and prevent heat leakage.

[0025] Furthermore, the ton container mechanism 4 includes: a ton container 41, a mounting frame 42, an inlet pipe 43, and an outlet 44; The ton container 41 is installed inside the mounting frame 42, which is a mesh structure. One end of the inlet pipe 43 is connected to the external supply mechanism, and the other end is connected to the inside of the ton container 41. One end of the outlet 44 is connected to the inside of the ton container 41, and the other end is equipped with a discharge switch. The ton container 41 is equipped with a control mechanism 7.

[0026] In this embodiment, please refer to Figure 2As shown, the ton container 41 is a high-temperature resistant plastic container, designed to handle large-scale resin processing. The mounting frame 42 is a stainless steel mesh structure, its shape matching that of the ton container 41. The ton container 41 is snapped into the mounting frame 42. The mesh structure of the mounting frame 42 facilitates heat penetration from the heating zone to the outer wall of the ton container 41, ensuring uniform heating. The inlet pipe 43 is a high-temperature resistant rubber hose, one end of which is sealed to an external supply mechanism via a quick connector, and the other end is connected to the ton container 41. A shut-off valve is installed on the inlet pipe 43 to control the delivery and shut-off of the resin. The outlet pipe 44 is a stainless steel pipe with a high-temperature resistant sealing valve to control the discharge of the heated resin.

[0027] In this embodiment, during use, the shut-off valve of the inlet pipe 43 is first opened, and the external supply mechanism injects the resin to be processed into the ton 41 through the inlet pipe 43. After the injection is completed, the shut-off valve is closed. After the resin is heated, the sealing valve of the outlet 44 is opened, and the resin is discharged from the outlet 44 under the action of gravity, thus completing the batch processing.

[0028] Furthermore, the drive mechanism 5 includes: a drive component 51, a main bevel gear 52, a secondary bevel gear 53, a stabilizing frame 54, a rotating rod 55, a threaded portion 56, and a guide frame 57; The drive component 51 is located at the center of the top of the outer shell 1. The output shaft of the drive component 51 rotates through the outer shell 1 and extends into the heating zone. One end of the output shaft of the drive component 51 located in the heating zone is connected to the main bevel gear 52. Multiple stabilizing frames 54 are arranged around the top of the inner shell 1. Each stabilizing frame 54 is rotatably equipped with a rotating rod 55. One end of each rotating rod 55 is rotatably connected to the side wall of the outer shell 1, and the other end is meshed with the main bevel gear 52 through the secondary bevel gear 53. Each rotating rod 55 has a threaded part 56 on the outer wall of the end near the side wall of the outer shell 1. The guide frame 57 is arranged in a grid shape. The guide frame 57 is set between the inner walls of the outer shell 1 through the stabilizing frame 54. The guide frame 57 is located on the side of the multiple rotating rods 55 near the top of the outer shell 1.

[0029] Furthermore, the guide frame 57 has a heat inlet 571 on the outer wall of the side of the heating zone near the ton barrel mechanism 4, and a heat dissipation port 572 on the outer wall of the guide frame 57 inside the heat dissipation cavity 11.

[0030] Furthermore, the heating mechanism 6 includes: a movable plate 61, a heating tape 62, and a sliding sleeve 63; The movable plate 61 is connected to the threaded part 56 through the sliding sleeve 63. Multiple heat tracing tapes 62 are evenly arranged on the side of the movable plate 61 away from the inner wall of the outer shell 1. The movable plate 61 is slidably connected to the outer wall of the guide frame 57.

[0031] In this embodiment, the application also includes a heating element that controls the heat tracing cable 62 to generate heat and transfer it to the heating zone. Compared to traditional heating methods, the heat tracing cable 62 features precise temperature control and rapid thermal response, allowing for adjustment of heating power according to actual needs and avoiding energy waste. Furthermore, the heat tracing cable 62 does not produce combustion exhaust gases, making it environmentally friendly and meeting the environmental protection requirements of modern industry. For media requiring a specific temperature, the heat tracing cable 62 can compensate for heat loss, maintaining the medium temperature within a set range.

[0032] In this application, the number of heating mechanisms 6 is set to four, and the four heating mechanisms 6 are located around the ton 41. It should be noted that when the four moving plates 61 are in the initial position, their upper sliding sleeves 63 are engaged with the threaded part 56 at one end near the inner wall of the outer casing 1. Figure 5 As shown.

[0033] For a preferred embodiment, please refer to Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, after the resin is added to the ton container 41, the heating element is activated, controlling the heating cables 62 on the four movable plates 61 located around the ton container 41 in their initial positions to generate heat. At this time, the heat will enter the heating zone as shown... Figure 5 The annular area shown in Figure A contacts the outer wall of the ton container 41 through the mesh structure of the mounting bracket 42, preheating the resin inside. After preheating, the drive unit 51 is activated, driving the main bevel gear 52 to rotate. Through meshing, the four secondary bevel gears 53 rotate synchronously, and the four rotating rods 55 also rotate synchronously. Through the meshing relationship between the threaded portions 56 (each threaded portion 56 has the same rotation direction) and the sliding sleeve 63, the four moving plates 61 move synchronously towards the outer wall of the ton container 41, reducing the distance between the multiple heating tapes 62 and the outer wall of the ton container 41. Therefore, the heating intensity received by the outer wall of the ton container 41 increases, completing the enhanced heating of the resin. In this application, while the drive unit 51 drives each heating mechanism 6 to perform enhanced heating, the control mechanism 7 can perform disturbance operation on the resin inside the ton container 41, avoiding the phenomenon of local overheating and damage to resin properties during the enhanced heating process.

[0034] In this embodiment, after the resin is heated and strengthened, simply controlling the drive unit 51 to reverse its direction will cause the four moving plates 61 to move synchronously away from the outer wall of the ton container 41. During this process, the control mechanism 7 will still agitate the resin inside the ton container 41. Unlike the agitation operation described above, this agitation operation is to improve the heat dissipation efficiency of the resin before use, thus saving time waiting for the resin to cool down. It should be noted that in this embodiment, the drive unit 51 can be a motor capable of both forward and reverse rotation.

[0035] In this embodiment, during the heating process, excess heat generated in the heating zone and a small amount of gas volatilized during resin heating enter the interior of the guide frame 57 through the heat inlet 571, and then enter the heat dissipation cavity 11 through the heat dissipation outlet 572. Heat flows along the cavity within the heat dissipation cavity 11, exchanging heat with the outer wall of the outer shell 1. Some heat is naturally dissipated through the outer wall of the outer shell 1, while the remaining heat and gas are discharged through the heat dissipation cavity 11.

[0036] Furthermore, the control mechanism 7 includes: a control housing 71, a trigger rod 72, a blade 73, a receiving port 74, a connecting frame 75, and a control assembly 76; The control housing 71 is located at the top of the inside of the ton 41. The end of the main bevel gear 52 away from the drive component 51 is connected to a trigger rod 72. The end of the trigger rod 72 away from the main bevel gear 52 rotates through the control housing 71 and is circumferentially arranged with multiple blades 73. The control housing 71 has multiple receiving ports 74 around its circumference. The multiple receiving ports 74 form a receiving group. The multiple receiving groups are arranged at equal intervals along the axis of the control housing 71. Each receiving port 74 is provided with a connecting frame 75. Each connecting frame 75 is provided with a control component 76. Each connecting frame 75 is rotatably connected to the trigger rod 72.

[0037] Furthermore, the control component 76 includes: a slide bar 761, a rocker arm 762, a trigger block 763, and a trigger spring 764; Among them, the sliding column 761 is slidably connected to the connecting frame 75, one end of the sliding column 761 is rotatably provided with a symmetrical rocker arm 762, the other end is provided with a trigger block 763, and a torsion spring is provided at the connection of the two rocker arms 762. The outer wall of the sliding column 761 is fitted with a trigger spring 764 that connects the connecting frame 75 and the trigger block 763.

[0038] Furthermore, the trigger lever 72 includes a protrusion 722 and a recess 721; Among them, multiple trigger groups are equidistantly arranged on the outer wall of the trigger rod 72 along its axial direction. Each trigger group is composed of multiple protrusions 722 and multiple recesses 721 arranged circumferentially on the outer wall of the trigger rod 72. The trigger surface shape of the trigger block 763 matches the protrusion 722 and the recess 721, and the number of trigger groups is the same as the number of receiving groups.

[0039] For a preferred embodiment, please refer to Figure 7 and Figure 8As shown, the trigger spring 764 is initially in a compressed, stored state. When the trigger block 763 is in its initial state, it abuts against the outer wall between the protrusion 722 and the recess 721 located in the same trigger group on the trigger rod 72. The drive member 51 drives the main bevel gear 52 to rotate, and simultaneously drives the trigger rod 72 to rotate synchronously. As the trigger rod 72 rotates, the trigger block 763 will engage with the trigger rod 72 and its components in a specified sequence, which is a cycle of "trigger rod 72 outer wall - protrusion 722 - trigger rod 72 outer wall - recess 721 - trigger rod 72 outer wall - protrusion 722".

[0040] In this embodiment, when the contact object of the trigger block 763 is the "transition from the outer wall of the trigger rod 72 to the protrusion 722", the protrusion 722 pushes the trigger block 763 up, and then the slide bar 761 will move away from the trigger rod 72. Figure 7 As shown by the solid straight arrow, the angle between the two pendulum rods 762 increases as follows: Figure 7 As shown by the solid arc, the resin exhibits an outward-expanding motion tendency. When the contact object of the trigger block 763 is the "transition from the protrusion 722 to the outer wall of the trigger rod 72", all components return to their initial state. When the contact object of the trigger block 763 is the "transition from the outer wall of the trigger rod 72 to the recess 721", the trigger block 763 will quickly extend into the recess 721 under the elastic force of the trigger spring 764, and then the slide rod 761 will move towards the trigger rod 72 as... Figure 7 As shown by the dashed straight arrow, this reduces the angle between the two pendulum rods 762. Figure 7 As shown by the dashed arc, the resin tends to be clamped inward. When the contact object of the trigger block 763 is the "transition from the recess 721 to the outer wall of the trigger rod 72", each component returns to its initial state.

[0041] In a preferred embodiment, the two levers 762 exert an alternating outward and inward clamping motion on the resin, collectively creating a disturbance operation on the resin. This disturbance operation occurs in two phases: the first occurs when the heating mechanism 6 intensifies the heating of the resin, and the second occurs when the heating mechanism 6 resets and waits for the resin to dissipate heat. These two identical disturbance operations serve different purposes: preventing localized overheating that could damage the resin's properties during the intensified heating process and improving the resin's heat dissipation efficiency before use, thus saving time spent waiting for the resin to cool down.

[0042] Furthermore, the control mechanism 7 also includes: a guide wheel 77; The guide wheel 77 is rotatably mounted on the control housing 71 at the receiving port 74, and the guide wheel 77 abuts against the swing arm 762.

[0043] In this embodiment, the guide wheel 77 can guide the two swing rods 762 during swinging, and also prevent the two swing rods 762 from being damaged by repeated contact friction with the receiving port 74, thus extending the service life of the device.

[0044] In another embodiment of this application, the threaded portions 56 on each rotating rod 55 are configured with different directions of rotation. In this case, the initial position of each moving plate 61 will change to the middle position of the threaded portion 56. Therefore, the execution method of the preheating treatment and enhanced heating processes in this application is changed, specifically: In a preferred embodiment, the positions of each moving plate 61 remain unchanged during preheating. During enhanced heating, the drive unit 51 is activated to drive the main bevel gear 52 to rotate alternately in both directions. Through the meshing of each secondary bevel gear 53, each rotating rod 55 rotates synchronously in both directions. At this time, due to the different rotation directions of each threaded part 56, each moving plate 61 will move alternately "closer to the outer wall of the ton 41 or away from the outer wall of the ton 41". The four side walls of the ton 41 will be subjected to alternating intensity of "low-intensity heating or high-intensity heating", which can more effectively prevent the resin inside the ton 41 from overheating locally and causing its own properties to fail.

[0045] It should be noted that in another embodiment of this application, a fire blanket (not shown in the figure) is provided on the outside of the outer casing 1. The fire blanket is woven from non-combustible fibers and, when covered on the fire source, can effectively block the contact between air and flame. The fire blanket itself is non-combustible and can form a physical barrier to prevent the flame from spreading to surrounding flammable materials, effectively preventing the fire from spreading, buying time for personnel evacuation and subsequent rescue, and ensuring the safety of personnel.

[0046] In specific implementation, a ton barrel mechanism 4 is coaxially arranged at the center of the outer shell 1. The ton barrel mechanism 4 is used to hold the resin to be heated. A drive mechanism 5 is fixedly arranged at the center of the top of the outer shell 1. The drive mechanism 5 is used to provide power to drive the heating mechanism 6 to move. Multiple heating mechanisms 6 are evenly distributed along the circumference inside the outer shell 1. The heating mechanism 6 is used to generate heat. A heating zone is formed between the inner wall of the outer shell 1 and the outer wall of the ton barrel mechanism 4. The heating mechanism 6 is located in this heating zone to ensure that the heat is concentrated on the ton barrel mechanism 4.

[0047] The above description is merely a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
