A heat storage and heat release device based on calcium-based materials

Abstract

This invention discloses a heat storage and release device based on calcium-based materials, including a heat exchanger. Multiple branch pipes distributed on the same pitch circle are arranged within the heat exchanger. Each branch pipe contains calcium-based heat storage and release material and a chain. One end of the chain is driven by a connecting handle sliding on the branch pipe, and the other end is driven by a reset mechanism on the heat exchanger. Through the chain within the branch pipe, the calcium-based material is stirred under the drive of the reset mechanism and the hook, eliminating localized accumulation of the calcium-based material, accelerating the reaction rate of the calcium-based material, and improving the heat storage and release efficiency. A crank-rocker mechanism, following a mushroom-shaped trajectory at point A, enables the hook to automatically complete the hooking, pulling, and separating actions with the connecting handle. In conjunction with the rotation of the rotating drum, the hook completes its rotation during its approach to the heat exchanger, sequentially aligning with the connecting handle of the next branch pipe, thus achieving sequential pulling of the chain within each of the multiple branch pipes, ensuring that the calcium-based material in all branch pipes is stirred.

Description

Technical Field

[0001] This invention relates to the field of stirring and mixing technology, specifically to a heat storage and release device based on calcium-based materials. Background Technology

[0002] A thermal energy storage and release device is a device that can store excess heat and release it for utilization when needed. Among various thermal energy storage and release systems, the calcium-based thermochemical energy storage system using calcium carbonate as a raw material has advantages such as low raw material cost, high reaction temperature, and high energy storage density. In existing technologies, thermal energy storage and release devices based on calcium-based materials place the calcium-based material inside a specific container, utilizing the container's outer wall to exchange heat with a heat exchange medium (such as air or molten salt). During the thermal storage phase, an external heat source provides energy to decompose calcium carbonate into calcium oxide and carbon dioxide; during the thermal release phase, carbon dioxide is introduced and recombines with calcium oxide to form calcium carbonate, releasing heat.

[0003] However, calcium-based materials may experience localized accumulation during the reaction process, leading to insufficient heat exchange between them and the heat exchange medium. This, in turn, limits the reaction rate and hinders further improvement in heat storage and release efficiency. Summary of the Invention

[0004] The purpose of this invention is to provide a heat storage and release device based on calcium-based materials to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a heat storage and heat release device based on calcium-based materials, comprising a heat exchanger, wherein a plurality of circumferentially arranged branch pipes are provided inside the heat exchanger, and each branch pipe is provided with calcium-based heat storage and heat release material and a chain, wherein one end of the chain is driven by a connecting handle slidably provided on the branch pipe, and the other end is driven by a reset mechanism provided on the heat exchanger.

[0006] The connecting handle has lugs that can be hooked by a hook, the bottom ends of multiple lugs are on the pitch circle, and the hook has a hook head that can come close to the connecting handle from behind the lugs so that the hook can hook the connecting handle.

[0007] The hook is driven by an active crank-rocker mechanism and a driven crank-rocker mechanism with the same structure. The rockers of the two crank-rocker mechanisms remain parallel during rotation. There is a point A on each of the two connecting rods. The trajectory of point A is mushroom-shaped. Both points A are rotatably connected to the hook. When point A is far away from the heat exchanger, the hook is on the outside of the pitch circle.

[0008] Both crank-rocker mechanisms are set inside a rotating cylinder concentric with the pitch circle. The rotating cylinder is set inside the support. At point A, near the heat exchanger, the hook is inside the pitch circle. The rotating cylinder rotates once, and the support and heat exchanger can be fixed to the ground.

[0009] Preferably, the crank-rocker mechanism has a crank length of L1, a connecting rod length of L2, a rocker length of L3, a distance from the crank rotation center to the rocker rotation center of L4, a vertical distance from point A to the connecting rod of L5, and a vertical distance from the hinge point of the crank and connecting rod to a straight line passing through point A and perpendicular to the connecting rod of L6. The ratio of L1:L2:L3:L4:L5:L6 is 1:2.5:2:2.5:0.5:2.

[0010] Preferably, multiple planetary gears are rotatably mounted on the rotating drum. The planetary gears are meshed with an internal gear ring, which can be fixed to the ground. The planetary gears are driven by an incomplete gear mechanism mounted on the rotating drum. The incomplete gear mechanism is driven by the active crank of the active crank-rocker mechanism. During the stroke near the heat exchanger at point A, the incomplete gear mechanism drives the planetary gears to rotate. During the stroke away from the heat exchanger at point A, the incomplete gear mechanism restricts the rotation of the planetary gears.

[0011] Preferably, the incomplete gear mechanism includes a driving incomplete gear and a driven incomplete gear. The driving incomplete gear is coaxially fixed with the driving crank of the driving crank rocker mechanism. One rotation of the driving incomplete gear can drive one rotation of the driven incomplete gear. The driven incomplete gear is mounted on a rotating drum and can drive a planetary gear.

[0012] Preferably, the driven incomplete gear is coaxially fixed with a worm gear, which is rotatably mounted inside the rotating drum. The worm gear is meshed with an input worm, which is also rotatably mounted inside the rotating drum. The worm gear and the input worm do not have self-locking characteristics. The worm is coaxially fixed with a gear A, which is rotatably mounted on the rotating drum. Gear B is meshed with a gear B, which is also rotatably mounted on the rotating drum. Gear B is meshed with a planetary gear.

[0013] Preferably, the active crank of the active crank rocker mechanism is driven by a main motor, which is fixed inside the rotating drum.

[0014] Preferably, an electric slip ring is installed on the side of the rotating drum away from the heat exchanger, and the electric slip ring is electrically connected to the main motor.

[0015] Preferably, the active crank rocker mechanism has a driven sprocket coaxially fixed to the active crank, the driven sprocket is connected to the active sprocket through a roller chain, the active sprocket is rotatably disposed inside the rotating drum, and the active sprocket is fixed on the input shaft of the main motor.

[0016] Preferably, the reset mechanism includes a mounting box and a coil spring. The mounting box is fixed on the heat exchanger, and a coil spring is provided inside the mounting box. One end of a rope is fixed to the output end of the coil spring, and the other end of the rope is fixed to a chain.

[0017] Preferably, the heat exchanger is externally fixed with insulation cotton.

[0018] Compared with the prior art, the beneficial effects of the present invention are: by using the chain in the branch pipe, under the drive of the reset mechanism and the hook, the calcium-based material is stirred, eliminating the problem of local accumulation of the calcium-based material, accelerating the reaction rate of the calcium-based material, and improving the heat storage and release efficiency.

[0019] The crank-rocker mechanism's mushroom-shaped trajectory at point A enables the hook to automatically engage, pull, and disengage from the connecting handle. In conjunction with the rotation of the drum, the hook completes its rotation as it approaches the heat exchanger, sequentially aligning with the connecting handle of the next branch pipe. This allows for the pull of the chains within multiple branch pipes one by one, ensuring that the calcium-based material in all branch pipes is stirred. Attached Figure Description

[0031] 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.

[0032] This invention provides a technical solution: a heat storage and release device based on calcium-based materials, such as... Figure 1 , 2 As shown, to facilitate heat storage and release, a heat exchanger 101 is included. The heat exchanger 101 is provided with multiple branch pipes 102. Each branch pipe 102 is provided with a calcium-based material for heat storage and release. The heat exchange medium enters from the inlet of the heat exchanger 101, passes between the branch pipes 102, exchanges heat with the branch pipes 102, and then leaves from the outlet of the heat exchanger 101. The branch pipes 102 have gas inlets and outlets. When storing heat, the calcium-based material decomposes calcium carbonate into calcium oxide and carbon dioxide when heated. When releasing heat, carbon dioxide is introduced into the calcium oxide to generate calcium carbonate and release heat.

[0033] like Figure 1-3 As shown, in order to promote the reaction of the calcium-based material, multiple branch pipes 102 are arranged circumferentially, and a chain 104 is provided in each branch pipe 102. One end of the chain 104 is fixed to the connecting handle 105, which is slidably disposed in the branch pipe 102. The other end of the chain 104 is driven by a reset mechanism 106, which is disposed on the heat exchanger 101. By pulling the connecting handle 105, the chain 104 can be driven, thereby stirring the calcium-based material in the branch pipe 102 and promoting the reaction of the calcium-based material. After the connecting handle 105 is released, the chain 104 returns to its initial position under the action of the reset mechanism 106.

[0034] like Figure 1-5 As shown, to facilitate the operation of the connecting handle 105, the connecting handle 105 can be hooked by the hook 107, and the connecting handle 105 has an ear plate 115 (shown in...). Figure 2 In the middle), the bottom ends of multiple ear plates 115 are located on the pitch circle 103, that is, the ear plates 115 of the connecting handle 105 are located outside the pitch circle 103, and the hook 107 has a hook head 116 (shown in the middle). Figure 4 (In the middle), the hook 116 can approach the ear plate 115 from the back of the ear plate 115 (i.e., the side of the ear plate 115 closest to the heat exchanger 101) and then approach the connecting handle 105 (e.g. Figure 10 As shown), when the hook head 116 contacts the ear plate 115, the pull hook 107 hooks the connecting handle 105.

[0035] The hook 107 is driven by an active crank-rocker mechanism 200 and a driven crank-rocker mechanism 300, which are identical in structure. The crank-rocker mechanism is a common mechanism, including a crank, connecting rod, rocker arm, and frame. One end of the crank is hinged to the frame, the other end of the crank is hinged to one end of the connecting rod, the other end of the connecting rod is hinged to one end of the rocker arm, and the other end of the rocker arm is also hinged to the frame. In this embodiment, the frame is fixed inside the rotating drum 108. The active rocker arm 203 of the active crank-rocker mechanism 200 and the driven rocker arm 303 of the driven crank-rocker mechanism 300 remain parallel during rotation. Both the active connecting rod 202 and the driven connecting rod 302 have a point A. The trajectory of point A is mushroom-shaped (the trajectory is shown in...). Figure 5 (In the middle), the mushroom-shaped trajectory has two extreme positions, one of which is the furthest from the heat exchanger 101 (i.e., Figure 5 (Middle left extreme position), another extreme position (i.e.) Figure 5 The distance from the rightmost extreme position to the heat exchanger 101 is minimized. The mushroom-shaped trajectory is divided into an upper and lower trajectory by these two extreme positions. The rotation direction of the active crank 201 needs to satisfy the following condition: when point A is close to the heat exchanger 101, that is, when the horizontal distance between point A and the heat exchanger 101 is shortened (i.e.,... Figure 4 The middle hook moves to the left. Figure 5 and Figure 6 As the middle hook 107 moves to the right, point A moves along a mushroom-shaped downward trajectory. When point A moves away from heat exchanger 101, that is, when the horizontal distance between point A and heat exchanger 101 increases (i.e., when...), the horizontal distance between point A and heat exchanger 101 increases. Figure 4 The middle hook moves to the right. Figure 5 and Figure 6 (The middle hook 107 moves to the left), point A moves along the upper trajectory of the mushroom shape, in... Figure 5 , 6 In the middle, the driving crank 201 needs to be rotated counterclockwise, that is Figure 5The driven crank 301 rotates in the direction indicated by the arrow, and both points A are rotatably connected to the hook 107. Since the driving rocker 203 and the driven rocker 303 remain parallel during rotation, the motion trajectory of any point on the hook 107 is the same in size as the motion trajectory of point A but in a different position. When the stroke of point A is close to the heat exchanger 101, the top of the hook head 116 of the hook 107 is inside the pitch circle 103. At this time, the hook 107 is separated from the connecting handle 105. When the stroke of point A is away from the heat exchanger 101, the top of the hook head 116 of the hook 107 is outside the pitch circle 103. The hook head 116 approaches the ear plate 115 from behind and then approaches the connecting handle 105. At this time, the hook 107 can hook the connecting handle 105.

[0036] The rotation of the active crank 201 of the active crank-rocker mechanism 200 drives the active connecting rod 202 to move, which in turn drives the active rocker 203 to rotate. The movement of the active connecting rod 202 drives the hook 107 to move, which in turn drives the driven connecting rod 302 of the driven crank-rocker mechanism 300 to move, which in turn drives the driven crank 301 and the driven rocker 303 to rotate. At point A, near the heat exchanger 101, the hook 107 is inside the pitch circle 103 and can approach the connecting handle 105. At point A, away from the heat exchanger 101, the hook 107 is outside the pitch circle 103 and can hook the connecting handle 105, which in turn drives the connecting handle 105 to slide, thereby pulling the chain 104.

[0037] like Figure 1 As shown, in order to facilitate the pulling of the chains 104 in the multiple branch pipes 102, the active crank rocker mechanism 200 and the driven crank rocker mechanism 300 are both set in the rotating drum 108. The rotation center of the rotating drum 108 coincides with the center of the pitch circle 103. The rotating drum 108 is rotatably set in the bracket 109. When the stroke is close to the heat exchanger 101 at point A, the rotating drum 108 performs one rotation, so that the movement plane of the hook 107 coincides with the plane where the center of the next connecting handle 105 is located (that is, the hook 107 moves to be close to the next connecting handle 105). The bracket 109 and the heat exchanger 101 can be fixed on the ground.

[0038] As the travel distance from point A away from heat exchanger 101 decreases, the rotating drum 108 stops rotating, and the hook 107 engages with the connecting handle 105, causing the connecting handle 105 to slide, which in turn pulls the chain 104, moving point A to... Figure 5 , 6When the hook 107 is in the left extreme position, the top of the hook head 116 moves from the outside of the pitch circle 103 to the inside of the pitch circle 103. At this time, the hook 107 separates from the connecting handle 105, and the chain 104 is reset under the action of the reset mechanism 106. Then, point A changes direction and moves towards the heat exchanger 101. At this time, the hook 107 is inside the pitch circle 103. Rotating the rotating drum 108 can make the movement plane of the hook 107 coincide with the plane where the center of the next connecting handle 105 is located.

[0039] In summary, the chain 104 inside the branch pipe 102, driven by the reset mechanism 106 and the hook 107, stirs the calcium-based material, eliminates the problem of local accumulation of the calcium-based material, accelerates the reaction rate of the calcium-based material, and improves the heat storage and release efficiency.

[0040] By using the mushroom-shaped trajectory of the active crank rocker mechanism 200 and the driven crank rocker mechanism 300 at point A, the hook 107 can automatically complete the hooking, pulling and separating actions with the connecting handle 105. In conjunction with the rotation of the rotating drum 108, the hook 107 completes the rotation during its stroke as it approaches the heat exchanger 101, and is sequentially aligned with the connecting handle 105 of the next branch pipe 102, thereby realizing the sequential pulling of the chain 104 in multiple branch pipes 102, ensuring that the calcium-based material in all branch pipes 102 can be stirred.

[0041] like Figure 5 As shown, the specific proportions for the mushroom-shaped trajectory achieved by the active crank-rocker mechanism 200 and the driven crank-rocker mechanism 300 are as follows: the length of the crank in the crank-rocker mechanism is L1, the length of the connecting rod is L2, the length of the rocker is L3, the distance from the rotation center of the crank to the rotation center of the rocker is L4, the vertical distance from point A to the connecting rod is L5, and the vertical distance from the hinge point of the crank and the connecting rod to the straight line passing through point A and perpendicular to the connecting rod is L6. The ratio of L1:L2:L3:L4:L5:L6 is 1:2.5:2:2.5:0.5:2.

[0042] like Figure 6 As shown, to facilitate the driving of the rotating drum 108, multiple planetary gears 110 are rotatably mounted on the rotating drum 108. The planetary gears 110 are meshed with an internal gear ring 111, which can be fixed to the ground. The planetary gears 110 are driven by an incomplete gear mechanism 400, which is mounted on the rotating drum 108 and driven by the active crank 201 of the active crank rocker mechanism 200. During the stroke near the heat exchanger 101 at point A, the incomplete gear mechanism 400 drives the planetary gears 110 to rotate. During the stroke away from the heat exchanger 101 at point A, the incomplete gear mechanism 400 restricts the rotation of the planetary gears 110.

[0043] During the stroke near heat exchanger 101 at point A, the rotation of the drive crank 201 drives the planetary gear 110 to rotate via the incomplete gear mechanism 400. That is, the rotation of the drive crank 201 in the drive crank-rocker mechanism 200 drives the incomplete gear mechanism 400, which in turn causes the planetary gear 110 to rotate relative to the rotating cylinder 108. Since the planetary gear 110 is meshed with the fixed internal gear ring 111, according to the gear meshing principle, when the planetary gear 110 rotates, it inevitably rolls along the tooth surface of the internal gear ring 111. This rolling motion forces the planetary gear 110 to revolve around the central axis of the internal gear ring 111. Because the planetary gear 110 is rotatably mounted on the rotating cylinder 108, its revolve motion is directly converted into the rotational motion of the rotating cylinder 108 around the center of the internal gear ring 111, thus realizing the rotation of the rotating cylinder 108 relative to the fixed internal gear ring 111. At point A, away from heat exchanger 101, the incomplete gear mechanism 400 restricts the rotation of planetary gear 110, thereby restricting the rotation of drum 108.

[0044] like Figure 7 , 8 As shown, the specific structure of the incomplete gear mechanism 400 is as follows: The incomplete gear mechanism 400 includes a driving incomplete gear 401 and a driven incomplete gear 402. The driving incomplete gear 401 is coaxially fixed with the driving crank 201 of the driving crank rocker mechanism 200. The driving incomplete gear 401 is provided with a convex arc 403, and the driven incomplete gear 402 is provided with a concave arc 404. During one revolution of the driving incomplete gear 401, the driving incomplete gear 401 first meshes with the driven incomplete gear 402. When the driving incomplete gear 401 and the driven incomplete gear 402 disengage, the convex arc 403 of the driving incomplete gear 401 contacts the concave arc 404 of the driven incomplete gear 402. The driven incomplete gear 402 is rotatably mounted on the rotating drum 108 and can drive a planetary gear 110.

[0045] When the travel is near heat exchanger 101 at point A, the rotation of the active crank 201 of the active crank rocker mechanism 200 can drive the active incomplete gear 401 to rotate. The active incomplete gear 401 meshes with the driven incomplete gear 402, thereby driving the driven incomplete gear 402 to rotate, which in turn drives the planetary gear 110 to rotate. When the travel is away from heat exchanger 101 at point A, the active incomplete gear 401 and the driven incomplete gear 402 disengage. The convex arc 403 of the active incomplete gear 401 contacts the concave arc 404 of the driven incomplete gear 402, thereby restricting the rotation of the driven incomplete gear 402, which in turn restricts the rotation of the planetary gear 110.

[0046] like Figure 6 , 7As shown in Figure 9, the specific structure of the driven incomplete gear 402 driving the planetary gear 110 is as follows: The driven incomplete gear 402 is coaxially fixed with a worm gear 405, which is rotatably disposed inside the rotating drum 108. The worm gear 405 is meshed with a worm 406, which is also rotatably disposed inside the rotating drum 108. The worm gear 405 and the worm 406 do not have self-locking characteristics. The worm 406 is coaxially fixed with an A gear 407, which is rotatably disposed on the rotating drum 108. The A gear 407 is meshed with a B gear 408, which is also rotatably disposed on the rotating drum 108. The B gear 408 is meshed with a planetary gear 110.

[0047] The rotation of the driven incomplete gear 402 can drive the worm gear 405 to rotate, which in turn drives the worm 406 to rotate, which in turn drives the A gear 407 to rotate, which in turn drives the B gear 408 to rotate, which in turn drives the planetary gear 110 meshing with the B gear to rotate. The other planetary gears 110 are driven structures and play an auxiliary support role.

[0048] like Figure 6 As shown, the specific driving method of the active crank rocker mechanism 200 is as follows: the active crank 201 of the active crank rocker mechanism 200 is driven by the main motor 113, which is fixed inside the rotating drum 108.

[0049] like Figure 6 As shown, since the main motor 113 is installed inside the rotating drum 108, and the power supply line needs to be connected from the fixed component, an electric slip ring 112 is installed on the side of the drum 108 away from the heat exchanger 101 to ensure reliable power transmission between the rotating and fixed components. The electric slip ring 112 is a common component for transmitting power between the rotating and fixed components, comprising two core components: an annular conductive component fixedly connected to the rotating component and a contact component fixedly connected to the fixed component. The contact component is used to connect to an external power source. In this embodiment, the rotating component is the drum 108, and the fixed component is the internal gear ring 111. The annular conductive component of the electric slip ring 112 is fixed to the drum 108 and electrically connected to the main motor 113. The contact component of the electric slip ring 112 is fixedly installed on the internal gear ring 111. When the drum 108 rotates, the annular conductive component rotates accordingly, while the contact component remains stationary, and the two continuously conduct current through sliding contact. This structure ensures a stable power supply to the main motor 113 during rotation and prevents the power cord from getting tangled due to the rotation of the drum 108, thus ensuring the long-term reliable operation of the device.

[0050] like Figure 7As shown, the specific structure of the main motor 113 driving the active crank rocker mechanism 200 is as follows: the active crank 201 of the active crank rocker mechanism 200 is coaxially fixed with a driven sprocket, the driven sprocket is connected to the active sprocket through a roller chain 114, and the active sprocket is fixed on the input shaft of the main motor 113.

[0051] The main motor 113 can drive the drive sprocket to rotate, which in turn drives the driven sprocket to rotate through the roller chain 114, thereby driving the drive crank 201 to rotate.

[0052] like Figure 1 As shown, in order to facilitate the reset of chain 104, the reset mechanism 106 includes a mounting box and a coil spring. The mounting box is fixed on the heat exchanger 101, and a coil spring is provided inside the mounting box. One end of a rope is fixed to the output end of the coil spring, and the other end of the rope is fixed to the chain 104.

[0053] After the connecting handle 105 separates from the hook 107, the coil spring tightens, which in turn causes the rope to slide, which in turn causes the chain 104 to slide, so that the chain 104 returns to its initial position.

[0054] To improve the heat insulation effect of heat exchanger 101, heat exchanger 101 is externally fixed with insulation cotton.

[0055] Working process: The rotation of the active crank 201 of the active crank rocker mechanism 200 can drive the active connecting rod 202 to move, which in turn drives the active rocker 203 to rotate. The movement of the active connecting rod 202 can drive the hook 107 to move, which in turn drives the driven connecting rod 302 of the driven crank rocker mechanism 300 to move, which in turn drives the driven crank 301 and the driven rocker 303 to rotate. At point A, near the heat exchanger 101, the hook 107 is inside the pitch circle 103 and can approach the connecting handle 105. At point A, away from the heat exchanger 101, the hook 107 is outside the pitch circle 103 and can hook the connecting handle 105, which in turn drives the connecting handle 105 to slide, thereby pulling the chain 104.

[0056] When point A moves away from heat exchanger 101, the rotating drum 108 stops rotating, and the hook 107 can hook the connecting handle 105, thereby causing the connecting handle 105 to slide, which in turn pulls the chain 104. When point A moves to its limit position, the hook 107 separates from the connecting handle 105, and the chain 104 is reset under the action of the reset mechanism 106. Then point A changes direction and moves towards heat exchanger 101. At this time, the hook 107 is inside the pitch circle 103. Rotating the rotating drum 108 can make the plane of motion of the hook 107 coincide with the plane where the center of the next connecting handle 105 is located.

[0057] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
