Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of cremation devices, and specifically discloses a bone ash cooling device. BACKGROUND

[0002] The temperature of bone ash generated after the cremation of a corpse is extremely high, and can reach several hundred degrees. In view of the safety and efficiency of the subsequent embalming process (such as being put into a bone ash box), the bone ash must be cooled. At present, the industry generally uses a wind-cooled cooling device, and the basic principle is to form a negative pressure above the bone ash container through a suction hood, so as to suck away hot air and introduce surrounding cold air, thereby achieving the purpose of cooling. However, the bone ash cooling device in the prior art has obvious defects in structure design and functional principle, resulting in low cooling efficiency, uneven effect, and potential risks. At present, the common suction hood has a horizontal suction mode towards the center. That is, the cold air flows into the container horizontally from the edge, and is sucked away upwards after converging at the center of the container. This air flow mode has inherent technical drawbacks. The air flow will preferentially pass through the path with the smallest resistance, that is, the area near the edge and the surface of the container. This results in a large amount of cold air flowing through only the surface layer of the bone ash and the area near the container wall, and failing to fully penetrate and replace the hot air inside the bone ash pile. In the central bottom area of the bone ash container, due to the difficulty of the horizontal air flow in effectively covering and penetrating, a continuous high-temperature "core heat island" or "cooling dead zone" is easily formed. The cooling speed of the bone ash in this area is much slower than that of the surrounding and surface layer. In addition, when the bone ash is naturally accumulated, there are a large number of small pores inside. The air in these pores is a poor conductor of heat, and forms an effective heat insulation layer. Simply relying on external air flow suction is difficult to break through this "heat insulation barrier", and the speed of heat conduction from the inside to the outside is very slow.

[0003] Therefore, the application provides a bone ash cooling device to solve the above-mentioned defects. SUMMARY

[0004] The purpose of this invention is to solve the problems existing in the background art, and to propose a cremated remains cooling device, including a rail frame, a hydraulic drive device, a transport vehicle, a support plate, a fan, and a suction hood. Two sets of hydraulic drive devices are provided and respectively installed on both sides of the outer wall of the rail frame. The telescopic ends of the two sets of hydraulic drive devices are connected to one side of the outer wall of the transport vehicle. The transport vehicle slides above and outside the rail frame. The fan is located on one side of the rail frame. The fan's exhaust port is connected to an L-shaped rigid pipe, and the fan's exhaust port is connected to an external pipe. A [further details about the L-shaped rigid pipe are missing]. The clamp mechanism is connected to a telescopic component. An L-shaped frame is fixedly installed at the telescopic end of the telescopic component. The bottom end of the L-shaped frame is connected to the top of the suction hood through a set clamping component. The end of the L-shaped rigid pipe away from the fan is connected to a telescopic flexible hose. Both sides of the lower interior of the telescopic flexible hose are connected to the interior of the suction hood through connected bends. Slide rail mechanisms are symmetrically installed on both sides of the outer wall of the suction hood. A connecting rod is fixedly installed on the upper surface of one side of the slide rail mechanism. A swing deflector mechanism is set above the connecting rod. A lever is installed at equal intervals along the horizontal direction on the lower surface of the connecting rod.

[0005] In the above technical solution, the clamping mechanism further includes a clamp that is fixedly sleeved on the outside of the L-shaped rigid pipe, and fixed plates are fixedly installed on both sides of the outer wall of the clamp, and the telescopic component is arranged inside the fixed plate.

[0006] In the above technical solution, the telescopic component further includes a first hydraulic rod fixedly installed inside the upper part of the fixed plate, and the telescopic end of the first hydraulic rod is connected to the upper surface of the L-shaped frame.

[0007] In the above technical solution, the slide rail mechanism further includes a guide frame fixedly installed on one side of the outer wall of the suction hood, a slide groove is provided inside the guide frame, a slide rod is slidably installed inside the slide groove, and the connecting rod is fixedly installed on the upper surface of one side of the slide rod.

[0008] In the above technical solution, further, multiple telescopic hydraulic rods are fixedly installed inside one end of the guide frame, and the telescopic ends of the multiple telescopic hydraulic rods are fixedly connected to the outer wall of one side of the slide rod.

[0009] In the above technical solution, the swing deflector mechanism further includes a connecting seat fixedly installed above the connecting rod, a second rotating shaft rotatably installed inside the lower part of the connecting seat, a first rotating shaft rotatably installed inside the upper part of the connecting seat, a second gear fixedly sleeved on one end of the second rotating shaft, a first gear fixedly sleeved on one end of the first rotating shaft, the first gear meshing with the second gear, a fixed seat fixedly sleeved on the side of the first rotating shaft away from the first gear, and an arc-shaped plate fixedly installed above the fixed seat.

[0010] In the above technical solution, further, there are slopes extending downward on both sides of the arc plate, a motor is fixedly installed at the end of the second rotating shaft away from the second gear, a protective shell is fixedly sleeved on the outside of the motor, and the protective shell is fixedly installed on the outer wall of the connecting seat.

[0011] In the above technical solution, the mounting component further includes mounting rods that are fixedly installed on both sides of the top of the suction hood. U-shaped tubes are fixedly installed on both sides of the inner side of the two mounting rods. One end of the L-shaped frame is fixedly fitted into the middle of the outside of the U-shaped tube. Reinforcing frames are fixedly installed on both outer walls of the L-shaped frame near the corner.

[0012] Compared with the prior art, the present invention has the following beneficial effects: 1. By using multiple levers installed on the suction hood that can move synchronously with it, during the cooling process, the levers can penetrate deep into the surface of the ashes and move horizontally, thereby effectively breaking the heat-insulating air layer formed inside the ashes due to static accumulation, exposing the high-temperature parts buried deep inside, greatly increasing the contact area and ventilation efficiency between the ashes and the cooling airflow, fundamentally overcoming the technical obstacle that it is difficult to overcome the heat insulation effect of the accumulated body by simply relying on airflow.

[0013] 2. Through the installation of a motor, first gear, second gear, first shaft, and second shaft, the baffle plate can be driven to swing. Combined with a horizontally movable sliding rod, this breaks the traditional, single, fixed horizontal centripetal airflow pattern. The periodic swinging of the baffle plate continuously changes the airflow direction and pressure distribution within the enclosure, forming a dynamic, dead-zone-free three-dimensional airflow field. This forces cold air to penetrate all layers of the urn, especially the central bottom area, thus solving the problem of localized overheating caused by uneven airflow distribution and ensuring uniform and rapid cooling of the entire urn.

[0014] 3. Through the coordinated use of the telescopic and sliding mechanisms, the relative position of the swing baffle mechanism inside the suction hood and the cremated remains can be precisely adjusted. Combined with the adjustable airflow guiding structure, it can adapt to the size of various cremated remains containers and the height of cremated remains stacking. There is no need to manually adjust the shape of the cremated remains, which not only improves the convenience of operation, but also avoids the loss of cremated remains that may be caused by manual contact.

[0017] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0018] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and therefore the invention is not limited to the specific embodiments disclosed below.

[0019] like Figures 1-7The illustrated cremated remains cooling device includes a rail frame 1, a hydraulic drive unit 2, a transport vehicle 3, a support plate 4, a fan 6, and a suction hood 5. Two sets of hydraulic drive units 2 are installed on opposite sides of the outer wall of the rail frame 1. The telescopic ends of the two sets of hydraulic drive units 2 are connected to one side of the outer wall of the transport vehicle 3. The transport vehicle 3 slides above and outside the rail frame 1. The fan 6 is located on one side of the rail frame 1. An L-shaped rigid pipe 8 is connected to the fan 6's exhaust port, and an external pipe 7 is connected to the fan 6's exhaust port. Telescopic components are correspondingly connected to the upper part of the L-shaped rigid pipe 8 via a clamping mechanism. An L-shaped frame 13 is fixedly installed at the telescopic end of the telescopic component. The bottom end of the L-shaped frame 13 is connected to the top of the suction hood 5 through a set clamping piece. The end of the L-shaped rigid pipe 8 away from the fan 6 is connected to a telescopic flexible hose 12. The lower sides of the telescopic flexible hose 12 are connected to the inside of the suction hood 5 through a connecting bend 17. A slide rail mechanism is symmetrically installed on both sides of the outer wall of the suction hood 5. A connecting rod 27 is fixedly installed on the upper surface of one side of the slide rail mechanism. A swing baffle mechanism is set above the connecting rod 27. A toggle rod 18 is installed at equal intervals along the horizontal direction on the lower surface of the connecting rod 27. In this embodiment, the transport vehicle 3 has a groove for a suitable rail frame 1 inside, and a bearing is installed in the groove. This is a common industrial transport mechanism. The fan 6 is a low-noise centrifugal fan 6. The external pipe 7 of the exhaust port is connected to the outside through an external pipe to avoid hot air backflow. The telescopic hose 12 can move and deform as the suction hood 5 moves up and down, avoiding the pipe from being pulled and torn.

[0020] Specifically, during operation, the transport vehicle 3 moves along the rail frame 1 under the push of the hydraulic drive device 2, delivering the carrying plate 4 to the working position below the suction hood 5. After the fan 6 is started, hot air is drawn in through the L-shaped rigid pipe 8 and the telescopic flexible hose 12. At the same time, the lever 18 mechanically turns the ashes, and the swing baffle mechanism changes the airflow distribution to achieve three-dimensional uniform cooling.

[0021] The clamping mechanism includes a clamp 10 that is fixedly sleeved on the outside of the L-shaped rigid tube 8. Fixed plates 9 are fixedly installed on both sides of the outer wall of the clamp 10. The telescopic component is set inside the fixed plate 9. The telescopic component includes a first hydraulic rod 11 that is fixedly installed inside the fixed plate 9. The telescopic end of the first hydraulic rod 11 is connected to the upper surface of the L-shaped frame 13. In this embodiment, the sleeve 10 is made of stainless steel and is fitted onto the L-shaped rigid pipe 8. Then, the installation of the first hydraulic rod 11 is supported by the fixing plates 9 on both sides, thereby ensuring that the extension and retraction of the first hydraulic rod 11 drives the suction hood 5 to rise and fall more stably.

[0022] The slide rail mechanism includes a guide frame 22 fixedly installed on one side of the outer wall of the suction hood 5. A slide groove 33 is opened inside the guide frame 22. A slide rod 16 is slidably installed inside the slide groove 33. A connecting rod 27 is fixedly installed on the upper surface of one side of the slide rod 16. A multi-section telescopic hydraulic rod 21 is fixedly installed inside one end of the guide frame 22. The telescopic end of the multi-section telescopic hydraulic rod 21 is fixedly connected to the outer wall of one side of the slide rod 16. In this embodiment, the slide rod 16 slides along the slide groove 33 of the guide frame 22, and the connecting rod 27 connects the slide rod 16 and the actuating rod 18 into a whole. When the multi-section telescopic hydraulic rod 21 drives the slide rod 16 to move, the actuating rod 18 moves horizontally to gently stir the ashes, breaking the porous heat insulation layer, thereby facilitating better heat absorption by the suction hood 5.

[0023] The oscillating deflector mechanism includes a connecting seat 23 fixedly installed above the connecting rod 27. A second rotating shaft 30 is rotatably installed inside the lower part of the connecting seat 23, and a first rotating shaft 25 is rotatably installed inside the upper part of the connecting seat 23. A second gear 28 is fixedly sleeved on one end of the second rotating shaft 30, and a first gear 24 is fixedly sleeved on one end of the first rotating shaft 25. The first gear 24 and the second gear 28 are meshed and connected. A fixed seat 32 is fixedly sleeved on the side of the first rotating shaft 25 away from the first gear 24. An arc-shaped plate 19 is fixedly installed above the fixed seat 32. Slope plates 20 extend downward on both sides of the arc-shaped plate 19. A motor 29 is fixedly installed on the end of the second rotating shaft 30 away from the second gear 28. A protective shell 26 is fixedly sleeved on the outside of the motor 29. The protective shell 26 is fixedly installed on the outer wall of the connecting seat 23. In this embodiment, when the curved tube 17 is sucking forcefully, the symmetrically arranged arc plates 19 on both sides can first move to the ends that are far apart from each other, so that the curved tube 17 can concentrate on sucking the ash on both sides. Then, the arc plates 19 are moved to the bottom of the curved tube 17. At this time, the motor 29 drives the second rotating shaft 30 to rotate, and the second gear 28 meshes to drive the first rotating shaft 25 to rotate. The first rotating shaft 25 drives the arc plate 19 to swing through the fixed seat 32, changing the airflow trajectory in the suction hood 5 and guiding the cold air to penetrate the ash pile. At the same time, it can avoid the problem of uneven heating caused by the concentrated adsorption of hot air in a fixed position. When the arc plate 19 swings, the slope plates 20 on both sides of the arc plate 19 swing synchronously, expanding the airflow guidance range and covering the edge of the ash pile to the center, avoiding airflow leakage. A protective shell 26 is installed outside the motor 29 to isolate high temperature and protect the motor 29.

[0024] The mounting components include mounting rods 15 that are fixedly installed on both sides of the top of the suction hood 5. U-shaped tubes 14 are fixedly installed on both sides of the inside of the two mounting rods 15. One end of the L-shaped frame 13 is fixedly fitted into the middle of the outside of the U-shaped tube 14. Reinforcing frames 31 are fixedly installed on both outer walls of the L-shaped frame 13 near the corner. In this embodiment, the L-shaped frame 13 is fitted onto the outside of the U-shaped tube 14 through the internally preset holes, and the mounting rod 15 fixes the U-shaped tube 14 to the suction hood 5, so as to achieve a stable connection between the L-shaped frame 13 and the suction hood 5 and ensure that the power of the telescopic component can be stably transmitted to the suction hood 5.

[0025] In summary, this invention solves the core technical problems of uneven cooling and low heat exchange efficiency in the prior art by using the semi-sealed lowering of the suction hood 5, the continuous exhaust of the fan 6, the mechanical turning of the cremated ash by the lever 18, and the dynamic interference of the internal airflow by the arc plate 19. This achieves rapid, uniform, and safe cooling of the cremated ash.

[0026] Working principle: After the cremation urn is transported out of the incinerator, it is moved to the support plate 4. The transport vehicle 3 is driven by the hydraulic drive device 2 to move along the outside of the rail frame 1 until the support plate 4 is accurately delivered to the bottom of the suction hood 5. When the ash on the carrier plate 4 is below the suction hood 5, the telescopic end of the first hydraulic rod 11 extends downward, driving the L-shaped frame 13 to descend as a whole. The L-shaped frame 13 drives the suction hood 5 to descend through the clamping parts until the lower edge of the suction hood 5 and the upper part of the carrier plate 4 maintain a gap in the suction state (ensuring the negative pressure suction effect while avoiding contact with the ash). Then, the fan 6 on one side of the rail frame 1 is started. The air intake of the fan 6 generates negative pressure through the L-shaped rigid pipe 8. The negative pressure is transmitted through the telescopic hose 12 to the bends 17 on both sides, and finally acts on the inside of the suction hood 5. The high-temperature hot air inside the suction hood 5 is drawn in by the negative pressure and enters the fan 6 in sequence through the bends 17, telescopic hose 12, and L-shaped rigid pipe 8. Then it is discharged to the designated area (such as outdoors or exhaust gas treatment device) through the external pipe 7 of the exhaust port of the fan 6, forming a continuous hot airflow circulation, which initially removes the heat from the surface of the ash. While the air is being drawn in for cooling, the motor 29 is powered on and its output drives the second shaft 30 to rotate. The second gear 28 outside the second shaft 30 meshes with the first gear 24 outside the first shaft 25, driving the first shaft 25 to rotate synchronously. The first shaft 25 drives the arc plate 19 to swing around the first shaft 25 through the fixed seat 32. The slope plates 20 on both sides of the arc plate 19 swing together. During the swing, the arc plate 19 and the slope plates 20 change the airflow direction inside the suction hood 5, so that the cold air that originally flowed horizontally to the center forms a downward airflow under the guidance of the baffle structure. This airflow accurately penetrates the surface of the ash pile and reaches the center area of ​​the bearing plate 4, eliminating the cooling dead zone of the traditional device and realizing synchronous heat exchange between the inside and the surface of the ash pile. The multi-section telescopic hydraulic rod 21 of the slide rail mechanism is activated simultaneously. Its telescopic end pushes the slide rod 16 in the slide groove 33 inside the guide frame 22 to slide. The connecting rod 27 on the upper surface of the slide rod 16 moves together. The agitator 18 on the lower surface of the connecting rod 27 gently stirs the ashes in the bearing plate 4 in the horizontal direction. The stirring action breaks the static air insulation layer formed by the pores inside the ashe pile, accelerates the heat conduction from the inside of the ashes to the surface, and, together with the airflow suction, greatly improves the heat exchange efficiency, avoiding the problem of surface cooling and internal residual heat in traditional devices. Once the ashes have cooled sufficiently, the fan 6 stops running, the mechanism resets, the suction hood 5 is lifted, and finally, the hydraulic drive unit 2 restarts, transporting the transport vehicle 3, connected to the cooled carrier plate 4 and the urn, to the work area, completing the entire cooling process.

[0027] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely principles of the invention.
