Description

Technical Field

[0001] This invention relates to the field of thermal energy storage equipment technology, specifically to a solid particle thermal energy storage device that integrates heat storage and heat exchange. Background Technology

[0002] As the global energy structure transitions towards a cleaner and lower-carbon model, the large-scale utilization of renewable energy sources such as solar and wind power, as well as the efficient recovery of industrial waste heat, have become crucial. However, these energy sources are generally intermittent and unstable, which severely restricts their grid connection, consumption, and efficient utilization. Thermal energy storage technology is a key core technology for solving these problems. It can achieve peak shaving and valley filling of energy, improving the flexibility and economy of the energy system. Among the many thermal storage technologies, they can be divided into sensible thermal storage, latent thermal storage, and thermochemical thermal storage according to the thermal storage principle. Among them, sensible thermal storage technology is widely used due to its wide availability of materials, relatively low cost, and high technological maturity. Traditional sensible thermal storage media mainly include heat transfer oil, molten salt, water or steam, and solid materials.

[0003] In existing technologies, solid particles often flow into the tank from a single pipe, causing localized accumulation and resulting in low heat exchange efficiency. Furthermore, due to their poor fluidity, solid particles are prone to uneven heat exchange during contact with the heat source, preventing them from fully storing heat. Summary of the Invention

[0004] To solve the above technical problems, the present invention is achieved through the following technical solution: a solid particle sample heat storage device integrating heat storage and exchange, comprising a support base, an insulated tank fixedly connected to the top of the support base, a feed pipe connected to the top of the insulated tank, a holding cylinder fixedly connected to the top and bottom of the inner wall of the insulated tank, a heat insulation device sleeved and slidably connected to the outer surface of the holding cylinder, the side of the heat insulation device being fixedly connected to the inner wall of the insulated tank, and a heat exchange tube fixedly connected to the inner wall of the holding cylinder, with both ends of the heat exchange tube penetrating the inside of the insulated tank. The top and bottom of the inner wall are fixedly connected to the heat insulation tank. A feeding device is rotatably connected to the top of the inner wall of the heat insulation tank. The top of the feeding device is connected to the feed pipe. A fixing rod is fixedly connected to the inner wall of the material container. A conical guide plate is fixedly connected to the end of the fixing rod away from the material container. A stirring and blowing device is rotatably connected to the bottom of the inner wall of the heat insulation tank located inside the material container. A discharge pipe is connected to the bottom of the heat insulation tank. A solenoid valve is fixedly connected to the discharge pipe. Air outlet holes are evenly opened on the inner wall of the material container.

[0005] Preferably, the feeding device includes a feeding pipe, a driven gear ring is sleeved and fixedly connected to the feeding pipe, a driving gear is meshed on the side of the driven gear ring, a drive shaft of a first motor is fixedly connected to the top of the driving gear, a cross connecting pipe is connected to the bottom of the feeding pipe, a sprinkling pipe is connected to the bottom of the cross connecting pipe, and feeding holes are opened on the side and bottom of the sprinkling pipe.

[0006] Preferably, a first connecting rod is fixedly connected to the inner wall of the feeding pipe, a first rotating shaft is fixedly connected to one end of the first connecting rod, a second rotating shaft is fixedly connected to the bottom of the first rotating shaft, and a spiral blade is sleeved and fixedly connected to the second rotating shaft. The top of the feeding pipe is connected to the feeding pipe, and the top of the feeding pipe is rotatably connected to the feeding pipe. The first motor is fixedly connected to the top of the heat insulation tank. High-temperature molten particles enter the cross connecting pipe through the feeding pipe and the feeding pipe, and are then conveyed to the spreading pipe. When the first motor is started, the drive shaft drives the active gear and the driven gear ring to rotate, thereby causing the feeding pipe to rotate. When the feeding pipe rotates, the first connecting rod drives the first and second rotating shafts and the spiral blades to rotate, pushing the particles to be conveyed downwards stably to prevent particle blockage. At the same time, the feeding pipe drives the cross connecting pipe and the spreading pipe to rotate, and the feeding hole of the spreading pipe makes a circular motion. Under the action of centrifugal force, the particles are evenly spread into the holding cylinder, and the conical guide plate further disperses the particles, causing them to fall into the area close to the heat exchange tube.

[0007] Preferably, the stirring and blowing device includes a rotating tube, with an arc-shaped heating and stirring plate evenly fixedly connected to the side of the rotating tube. The arc-shaped heating and stirring plate has through holes evenly opened on its side. The output end of a belt drive mechanism is sleeved and fixedly connected to the bottom of the side of the rotating tube, and the input end of the belt drive mechanism is fixedly connected to the drive shaft of a second motor. The rotating tube passes through the bottom of the inner wall of the heat insulation tank and is fixedly connected to the heat insulation tank. The second motor is fixedly connected to the bottom of the heat insulation tank through a bracket. After the particles fall into the holding cylinder, the second motor is started, and the drive shaft drives the rotating tube to rotate through the belt drive mechanism. The rotating tube drives the arc-shaped heating and stirring plate to rotate, stirring and heating the particles at the same time to prevent heat loss from the particles. The through holes on the stirring plate promote particle flow and mixing, ensuring that the particle temperature is uniform in all parts of the holding cylinder.

[0008] Preferably, the rotating tube has air outlet pipes evenly connected to its side, and air jet holes are evenly opened on the side of the air outlet pipes. The bottom of the rotating tube is connected to a connecting air pipe, and the end of the connecting air pipe away from the rotating tube is connected to the air outlet of an induced draft fan. The induced draft fan is fixedly connected to the bottom of the heat insulation tank. When the second motor drives the rotating tube to rotate, the induced draft fan starts synchronously, sending external air into the rotating tube through the air inlet, air outlet, and connecting air pipe. The air is transported to the air outlet pipe through the rotating tube and sprayed into the material container from the air jet holes. The rotating tube drives the air outlet pipe to rotate, and the air jet holes make circular motion, so that the gas acts evenly on the particle layer in the form of rotational diffusion.

[0009] Preferably, the insulation device includes a slide rail, a sliding guide block slidably connected to the inner wall of the slide rail, an insulation shell fixedly connected to the side of the sliding guide block away from the slide rail, air inlets evenly distributed on the side of the insulation shell, connecting blocks evenly fixedly connected to the bottom of the insulation shell, a movable end of a pneumatic piston rod fixedly connected to the bottom of the connecting blocks, the slide rail fixedly connected to the inner wall of the insulation tank, multiple sets of slide rails evenly distributed on the inner wall of the insulation tank, a fixed end of the pneumatic piston rod fixedly connected to the bottom of the insulation tank, and a movable end of the pneumatic piston rod penetrating... The insulation shell penetrates the bottom of the inner wall of the heat-insulating tank and is fixedly connected to the connecting block. The inner wall of the insulation shell is slidably connected to the side of the material container. When the equipment is not in operation and needs to be kept warm, the pneumatic piston rod is activated, and the movable end extends to push the connecting block and the insulation shell upward. The insulation shell slides stably along the slide rail through the sliding guide block, and the inner wall moves upward against the side of the material container. When the air inlet of the insulation shell is connected to the air outlet of the material container, the two form a closed insulation space. The residual heat gas of the stirring and blowing device enters the insulation space through the air outlet and air inlet, using the residual heat to keep the particles warm, while the insulation shell blocks the outside cold air.

[0010] This invention provides a solid particle sample thermal storage device integrating heat storage and exchange. It has the following beneficial effects: 1. This integrated heat storage and heat exchange device for solid particles utilizes a first motor to drive the feed pipe, enabling continuous and stable rotation. Simultaneously, the closely linked spiral blades also rotate, achieving stable conveying by leveraging the unique structure of the spiral blades. This applies a stable and continuous downward conveying force to the molten particles, effectively preventing particle accumulation and blockage within the feed and discharge pipes. This is particularly beneficial as molten particles tend to adhere to the pipe walls during cooling, preventing blockages. This ensures the continuity and stability of the entire conveying process. Furthermore, the first motor also drives the spreading... The feed tube rotates in a circular motion, allowing the particles to fall evenly from the feed hole under centrifugal force. Combined with the conical guide plate inside the feeding cylinder, the particles are further dispersed, ensuring that each particle falls precisely into the area close to the heat exchange tube. This achieves the dual purpose of anti-clogging conveying and uniform material distribution, significantly increasing the contact area between the high-temperature particles and the heat exchange tube. Compared to the traditional centralized feeding method, this method effectively avoids the problem of heat insulation layer formed by particle accumulation, which reduces heat exchange efficiency. It also reduces equipment downtime and energy waste caused by blockage or uneven material distribution, improving the overall operating efficiency and economic benefits of the system.

[0011] 2. This integrated heat storage and heat exchange device for solid particles features a second motor driving an arc-shaped heating and stirring plate. On one hand, the stirring breaks the static accumulation of particles, forcing them into full contact with the heat exchange tubes, thus addressing the issues of insufficient particle adhesion to the walls and weak heat exchange in the center. On the other hand, the arc-shaped plate's own heating function compensates for heat loss during particle transport, preventing a decrease in temperature difference due to particle temperature drop, thus providing continuous temperature control. Simultaneously, the through-holes on the stirring plate reduce resistance during particle stirring, promoting particle flow and mixing, ensuring consistent particle temperature across the container, avoiding localized overheating or low-temperature dead zones, further optimizing heat exchange efficiency, and improving the overall stability of heat storage and transfer within the heat storage and heat exchange device.

[0012] 3. This integrated heat storage and heat exchange device for solid particles utilizes a dynamic air jet system created by the combination of an induced draft fan and a rotating exhaust pipe. The air delivered by the induced draft fan is ejected circumferentially through the rotating exhaust nozzle. This airflow not only enhances the flow between particles, preventing particle agglomeration (which would hinder heat exchange), but also breaks up slightly accumulated particles through airflow impact, keeping them loose and increasing the probability of contact with the heat exchange tubes. This solves the problem of insufficient dispersion of fine particles by simple stirring, making it particularly suitable for particles with extremely poor flowability. It prevents particle agglomeration from affecting equipment operation and promotes uniform heat transfer within the particle group, allowing the heat from high-temperature particles to be more fully transferred to the heat exchange tubes, thus improving heat storage and heat exchange efficiency and equipment stability.

[0013] 4. This integrated heat storage and heat exchange device for solid particles, when not in operation, uses a pneumatic piston rod to push the insulation shell upwards. A sliding guide block ensures precise contact between the shell and the container, forming a relatively enclosed insulation space. Simultaneously, residual heat from the stirring and blowing device is introduced into the insulation space through the air outlet and inlet. This utilizes the residual heat to continuously insulate the particles in the container, preventing rapid heat loss due to low ambient temperatures and avoiding the need for reheating upon startup, thus saving energy. Furthermore, the insulation shell prevents the intrusion of cold air, reducing heat loss. This achieves both waste heat reuse and improved insulation performance during non-operation periods, reducing energy consumption and establishing a constant temperature foundation for the next heat exchange operation. It also shortens the preheating time after startup and improves overall energy efficiency. Attached Figure Description

[0016] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0017] For the first embodiment, please refer to... Figures 1-5This invention provides a technical solution: a solid particle sample heat storage device integrating heat storage and exchange, including a support base 1, an insulated tank 2 fixedly connected to the top of the support base 1, a feed pipe 3 connected to the top of the insulated tank 2, a holding cylinder 4 fixedly connected to the top and bottom of the inner wall of the insulated tank 2, a heat insulation device 5 sleeved and slidably connected to the outer surface of the holding cylinder 4, the side of the heat insulation device 5 fixedly connected to the inner wall of the insulated tank 2, a heat exchange pipe 6 fixedly connected to the inner wall of the holding cylinder 4, the two ends of the heat exchange pipe 6 passing through the top and bottom of the inner wall of the insulated tank 2 respectively and fixedly connected to the insulated tank 2, a feeding device 7 rotatably connected to the top of the inner wall of the insulated tank 2, the top of the feeding device 7 connected to the feed pipe 3, a fixing rod 8 fixedly connected to the inner wall of the holding cylinder 4, a conical guide plate 9 fixedly connected to the end of the fixing rod 8 away from the holding cylinder 4, a stirring and blowing device 10 passing through and rotatably connected to the bottom of the inner wall of the insulated tank 2 inside the holding cylinder 4, and a discharge pipe 11 connected to the bottom of the insulated tank 2. A solenoid valve 12 is fixedly connected to the upper part of the material cylinder 4. Air vents 13 are evenly distributed on the inner wall of the material cylinder 4. The feeding device 7 includes a feeding pipe 71. A driven gear ring 72 is sleeved and fixedly connected to the feeding pipe 71. A drive gear 73 meshes with the side of the driven gear ring 72. The drive shaft of the first motor 74 is fixedly connected to the top of the drive gear 73. A cross connecting pipe 75 is connected to the bottom of the feeding pipe 71. A sprinkling pipe 76 is connected to the bottom of the cross connecting pipe 75. Feeding holes 77 are opened on the side and bottom of the sprinkling pipe 76. A first connecting rod 711 is fixedly connected to the inner wall of the feeding pipe 71. A first rotating shaft 712 is fixedly connected to one end of the first connecting rod 711. A second rotating shaft 713 is fixedly connected to the bottom of the first rotating shaft 712. A spiral blade 714 is sleeved and fixedly connected to the second rotating shaft 713. The top of the feeding pipe 71 is connected to the feed pipe 3. The top of the feeding pipe 71 is rotatably connected to the feed pipe 3. The first motor 74 is fixedly connected to the top of the heat insulation tank 2.

[0018] In use, the molten granules are first introduced into the tank through the feed pipe 3. These granules are then fed into the discharge pipe 71. The molten granules continue to flow through the discharge pipe 71, passing through the connecting channel into the cross-shaped connecting pipe 75. Inside the cross-shaped connecting pipe 75, the granules are transported to the bottom sprinkling pipe 76. Finally, the granules are discharged through the side of the sprinkling pipe 76 and the bottom discharge hole 77. Simultaneously, the first motor 74 is started, and its drive shaft begins to rotate. The rotation of the drive shaft drives the connected drive gear 73 to rotate, which in turn drives the driven gear ring 72. The driven gear ring 72 then drives the discharge pipe 71 to rotate. During the rotation of the discharge pipe 71, the first connecting rod 711 on its inner wall also rotates. The rotation of the first connecting rod 711 drives the first rotating shaft 712 to rotate, which in turn drives the second rotating shaft 713 to rotate. The rotation of the rotating shaft 713 ultimately drives the spiral blades 714 to rotate. The rotation of the spiral blades 714 can effectively and stably transport the high-temperature molten granular material downwards, avoiding possible blockages during the transportation process, thus ensuring the smooth operation of the entire system. In addition, the rotation of the feed pipe 71 will also drive the cross connecting pipe 75 to rotate, and the rotation of the cross connecting pipe 75 will further drive the spreading pipe 76 to rotate. The rotation of the spreading pipe 76 causes the feed hole 77 to perform a circular motion. This motion allows the high-temperature molten granular material to be evenly scattered inside the holding cylinder 4 under the action of centrifugal force. Since the holding cylinder 4 is equipped with a conical guide plate 9, the scattered granular material can be further dispersed, ensuring that these granular materials can fall on the inner wall of the holding cylinder 4 near the heat exchange tube 6. This not only increases the contact area between the high-temperature granular material and the heat exchange tube 6, thereby improving the heat exchange efficiency, but also effectively avoids the accumulation problem caused by concentrated feeding of granular material, further ensuring the smoothness and efficiency of the heat exchange process.

[0019] For the second embodiment, please refer to... Figures 1-6 Based on the first embodiment, the present invention provides a technical solution: the stirring and blowing device 10 includes a rotating tube 101, an arc-shaped heating and stirring plate 102 is uniformly fixedly connected to the side of the rotating tube 101, through holes 103 are uniformly opened on the side of the arc-shaped heating and stirring plate 102, the output end of the belt drive mechanism 104 is sleeved and fixedly connected to the bottom of the side of the rotating tube 101, the input end of the belt drive mechanism 104 is fixedly connected to the drive shaft of the second motor 105, the rotating tube 101 penetrates the bottom of the inner wall of the heat insulation tank 2 and is fixedly connected to the heat insulation tank 2, and the second motor 105 is fixedly connected to the bottom of the heat insulation tank 2 by a bracket.

[0020] When in use, when the high-temperature molten salt is evenly sprinkled into the inside of the container cylinder 4 through the feeding device 7, the solid particles themselves have relatively poor fluidity, which makes it impossible for them to fully exchange heat with the heat exchange tube 6, thus affecting the heat storage effect, and the second motor 105 is started. The drive shaft of the second motor 105 begins to rotate, which in turn drives the input end of the belt drive mechanism 104 to rotate. The rotation of the input end of the belt drive mechanism 104 further drives its output end to rotate, which in turn drives the rotating tube 101 to rotate. The rotation of the rotating tube 101, in turn, drives the arc-shaped heating and stirring plate 102 to rotate. While the arc-shaped heating and stirring plate 102 is rotating, it also heats the particles inside the material container 4. This effectively prevents the particles from losing heat, thus achieving continuous temperature control. In addition, the through holes 103 on the arc-shaped heating and stirring plate 102 promote the stirring process, helping the particles to flow and mix better, ensuring that the temperature of the particles in all parts of the material container 4 is evenly distributed. This not only improves the heat exchange efficiency between the particles and the heat exchange tube 6, but also further improves the overall heat exchange efficiency of the entire heat storage and heat exchange equipment, making the operation of the entire device more efficient and stable.

[0021] Third embodiment, please refer to Figures 1-7 Based on the second embodiment, the present invention provides a technical solution: the side of the rotating tube 101 is uniformly connected with an air outlet pipe 1011, the side of the air outlet pipe 1011 is uniformly provided with air jet holes 1012, the bottom of the rotating tube 101 is connected with a connecting air pipe 1013, the end of the connecting air pipe 1013 away from the rotating tube 101 is connected with the air outlet of the induced draft fan 1014, and the induced draft fan 1014 is fixedly connected to the bottom of the heat insulation tank 2.

[0022] In use, when the drive shaft of the second motor 105 rotates, it drives the rotating tube 101 to rotate, and simultaneously starts the induced draft fan 1014. The induced draft fan 1014 then starts working, forcefully drawing in external air through the air inlet and guiding it to the air outlet. Subsequently, this air is transported through the air outlet of the induced draft fan 1014 to the connecting air pipe 1013. The connecting air pipe 1013 is responsible for transporting this air into the interior of the rotating tube 101. Inside the rotating tube 101, the air continues to flow along the pipe and is eventually transported to the air outlet pipe 1011 on the side of the rotating tube 101. The jet nozzle 1012 on the side of the air outlet pipe 1011 then sprays this air into the material container 4 in the form of a jet. At the same time, the rotation of the rotating tube 101 drives the air outlet pipe 1011 to rotate as well. The rotation of the nozzle further drives the jet nozzle 1012 to rotate, so that the gas ejected from the jet nozzle 1012 can act evenly on the particle layer inside the container 4 in a rotational diffusion manner. This dynamic jetting method not only enhances the air flow between particles and effectively avoids local overheating or agglomeration, but also further disperses those particles that are piled up through the impact of the airflow. This dynamic jetting method can also promote the uniform transfer of heat in the particle group, thereby increasing the contact probability between the particles and the heat exchange tube 6, so that the particles and the heat exchange tube 6 can achieve more sufficient contact, and thus make the heat exchange and heat storage process between the high-temperature particles and the heat exchange tube 6 more efficient, thereby improving the heat storage and exchange efficiency of the entire system and ensuring the efficient utilization of thermal energy.

[0023] For the fourth embodiment, please refer to [link / reference]. Figures 1-8 Based on the third embodiment, the present invention provides a technical solution: the heat preservation device 5 includes a slide rail 51, a sliding guide block 52 is slidably connected to the inner wall of the slide rail 51, a heat preservation shell 53 is fixedly connected to the side of the sliding guide block 52 away from the slide rail 51, air inlets 54 are evenly opened on the side of the heat preservation shell 53, connecting blocks 55 are evenly fixedly connected to the bottom of the heat preservation shell 53, the movable end of a pneumatic piston rod 56 is fixedly connected to the bottom of the connecting block 55, the slide rail 51 is fixedly connected to the inner wall of the heat insulation tank 2, multiple sets of slide rails 51 are provided and evenly distributed on the inner wall of the heat insulation tank 2, the fixed end of the pneumatic piston rod 56 is fixedly connected to the bottom of the heat insulation tank 2, the movable end of the pneumatic piston rod 56 penetrates the bottom of the inner wall of the heat insulation tank 2 and is fixedly connected to the connecting block 55, and the inner wall of the heat preservation shell 53 is slidably connected to the side of the material container 4.

[0024] In use, when the heat exchange equipment has completed heat exchange and is in a non-working state requiring special insulation, the gas injected by the stirring and blowing device 10, after the work is completed, utilizes the residual preheating of the injected gas after heat exchange for insulation, thereby activating the pneumatic piston rod 56. The movable end of the pneumatic piston rod 56 extends upward, pushing the connecting block 55 to move upward. The connecting block 55 drives the insulation shell 53 to move upward. The insulation shell 53 slides on the inner wall of the slide rail 51 via the sliding guide block 52, ensuring the stability and accuracy of the movement. As the insulation shell 53 rises, its inner wall tightly adheres to the side of the material cylinder 4 and slides upward along the side of the material cylinder 4. The rise of the insulation shell 53 drives the air inlet 54 to rise. When the air inlet 54 rises... When connected to the vent 13, a relatively closed insulation space is formed between the insulation shell 53 and the material container 4. At this time, the gas with residual heat previously blown out by the stirring and blowing device 10 enters this insulation space through the vent 13 and the inlet 54. Due to the blocking effect of the insulation shell 53, the intrusion of cold air from the outside is effectively reduced. At the same time, the residual heat of the gas is used to continuously keep the particles in the material container 4 warm, preventing the particles from losing heat quickly due to the low ambient temperature during the next heat exchange. This ensures that the inside of the tank can still maintain a suitable temperature when not in operation, preparing for the next heat exchange operation. This improves the insulation performance of the entire heat storage and exchange equipment during non-operation periods and reduces energy loss.

[0025] Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by those skilled in the art and related fields based on the embodiments of the present invention without inventive effort should fall within the scope of protection of the present invention. Structures, devices, and operating methods not specifically described and explained in the present invention, unless otherwise specified or limited, shall be implemented according to conventional means in the art.
