Description

Technical Field

[0001] This utility model relates to the field of heating device technology, and in particular to an energy-saving heating device. Background Technology

[0002] A heating device is a device that can convert various forms of energy, such as electrical energy, thermal energy, and chemical energy, into heat energy and use this heat energy to heat objects or spaces. During the transportation of raw materials, some raw materials may undergo a phase transition from liquid to solid. Since solid raw materials are inconvenient to access in storage containers, it is necessary to restore them to their original liquid state.

[0003] A search revealed Chinese patent publication number CN215638029U, which discloses an energy-saving heating device for building heating. The device includes a heating chamber and a heating pipe. A section of the heating pipe is externally fitted with a heating tube. The heating chamber contains a heating mechanism, which includes a circulating pump, a movable frame, a flow guide, a telescopic cylinder, a cylindrical transmission frame, a lead screw, a lead screw slider, an electric heating rod, a round shaft, and fan blades. The heating pipe has a first conduit and a second conduit connected externally. A third conduit is located between the first and second conduits, and a flow relief bladder is located between the third conduits. This device uses a water circulation heating method to heat the heating pipe, achieving uniform heating of the water, increasing the heating rate, saving energy, and providing pressure relief protection for the pipeline, thus extending the pipeline's service life.

[0004] The aforementioned patent mentions the beneficial effects: "This device uses a water circulation heating method to heat the heating pipe. The provided heating mechanism can achieve uniform heating of the water, which can increase the water heating rate and thus achieve energy saving. The provided third conduit and unloading bladder can realize pressure relief protection of the pipeline in the device, thereby increasing the service life of the pipeline." Although the above solution can improve the water heating rate, in the use of some existing heating devices, calcium and magnesium ions in the water will form scale during heating. The scale adheres to the inner wall of the heating device, which will reduce the heat transfer efficiency, resulting in a longer heating time, increased energy consumption, and reduced energy saving effect of the energy-saving heating device. Therefore, an energy-saving heating device is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an energy-saving heating device, which aims to improve the problem that some existing heating devices are difficult to clean of scale, thereby reducing heat transfer efficiency.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An energy-saving heating device includes a metal shell, a drive mechanism fixedly connected to the rear side of the metal shell, a tensioning mechanism fixedly connected to the bottom inner wall of the metal shell, multiple support columns fixedly connected to the left and right inner walls of the metal shell, a bushing fixedly connected to the inner wall of the metal shell, a steam pipe fixedly connected to the inner bottom of the metal shell, four heating copper tubes fixedly connected to the inner bottom of the steam pipe, a disassembly mechanism fixedly connected to the bottom of the heating copper tubes, a fixing frame provided inside the metal shell, and a storage tank provided inside the fixing frame.

[0008] The driving mechanism includes a base, the front side of which is fixedly connected to the rear left side of the metal shell, a motor is fixedly connected to the top of the base, a rotating rod one is fixedly connected to the driving end of the motor, a rotating rod two is rotatably connected to the inside right side of the metal shell, a belt is sleeved on the outside of the rotating rod one, multiple fixing plates are fixedly connected to the outside of the belt, and multiple brushes are fixedly connected to the other side of each fixing plate.

[0009] Furthermore, after the motor starts, it acts as a power source, driving rotating rod one to rotate. Rotating rod one, via a belt, drives rotating rod two to rotate synchronously, thus realizing the transmission and conversion of power. During the rotation of the belt, multiple fixed plates on its surface move accordingly. These fixed plates drive multiple brushes to move, cleaning the scale on the inner wall of the bottom of the metal casing, thereby restoring the good heat transfer efficiency of the metal casing. This enables the energy-saving heating device to operate efficiently, truly achieving the energy-saving goal.

[0010] As a further description of the above technical solution:

[0011] The tensioning mechanism includes two support plates. The bottom of the two support plates is fixedly connected to the bottom inner wall of the metal shell. An inner cavity is opened inside the support plate. A movable plate is slidably connected to the inner wall of the inner cavity. A rotating rod is fixedly connected to the adjacent side of the two movable plates. A tensioning wheel is rotatably connected to the outside of the rotating rod. Bolts are threadedly connected to both the front and rear sides of the metal shell.

[0012] Furthermore, during operation, the sliding direction and distance of the moving plate within the inner cavity can be precisely controlled by rotating the bolts on the front and rear sides of the metal casing. The movement of the moving plate causes the rotating rod to shift, thereby changing the position of the tensioning wheel. Because the tensioning wheel is rotatably connected to the rotating rod, its angle can be flexibly adjusted to fit the belt. This process precisely maintains the belt tension, ensuring that the power output from the motor is smoothly transmitted to the belt via the rotating rod. This guarantees that the brush continuously and efficiently cleans the scale on the inner wall of the bottom of the metal casing, maintains good heat transfer efficiency, and contributes to the efficient operation of the energy-saving heating device.

[0013] As a further description of the above technical solution:

[0014] The disassembly mechanism includes multiple connecting plates. The tops of two connecting plates are fixedly connected to the bottom sides of the heating copper tube. The connecting plates have square openings inside. The bottom of the metal shell has multiple cavities. The inner walls of the cavities are slidably connected to sliding plates. Square plates are fixedly connected to the bottom sides of the sliding plates. A rotating frame is rotatably connected to the adjacent sides of the two square plates. A telescopic rod is rotatably connected to the bottom of the sliding plates. A spring is sleeved on the outside of the telescopic rod. A locking block is fixedly connected to the top side of the rotating frame.

[0015] Furthermore, when it is necessary to fix the heating copper tube, rotate the rotating frame to engage the locking block with the elongated opening inside the metal casing. At this time, the sliding plate is fixed in position, and the square plates on both sides of the bottom of the sliding plate are embedded in the square opening inside the connecting plate, thus firmly connecting the heating copper tube to the metal casing and ensuring the stability of the heating copper tube during operation. When it is necessary to disassemble the heating copper tube, rotate the rotating frame in the opposite direction to disengage the locking block from the elongated opening. The sliding plate is unlocked and can move freely, thereby driving the square plates to disengage from the square opening, realizing the disassembly of the heating copper tube. During this process, the telescopic rod and the externally sleeved spring work together. When the rotating frame rotates, the telescopic rod extends and retracts, and the spring provides elastic force to assist the rotation. At the same time, it plays a buffering role during disassembly, avoiding damage to various components due to improper operation, facilitating timely maintenance and replacement of the heating copper tube, and ensuring the normal operation of the device.

[0016] As a further description of the above technical solution:

[0017] The outer side of the rotating rod one is rotatably connected to the inside of the left side of the metal shell, and the inner right side of the belt is sleeved on the outside of the rotating rod two;

[0018] Furthermore, driven by the motor, rotating rod one rotates at high speed inside the left side of the metal casing, establishing a power connection with rotating rod two via a belt. The right side of the belt is fitted over rotating rod two; when rotating rod one rotates, the belt moves in a circular motion, thus causing rotating rod two to rotate synchronously. This connection method ensures the continuity and stability of power transmission in the drive mechanism. With the assistance of the tensioning mechanism, the belt maintains appropriate tension, ensuring efficient and stable power transmission from the motor to the brush, providing stable power support for continuously cleaning scale from the bottom inner wall of the metal casing, and maintaining the efficient operation of the energy-saving heating device.

[0019] As a further description of the above technical solution:

[0020] The outer side of the tensioning wheel is in contact with the outer side of the belt, the adjacent side of the two bolts is in contact with the distant side of the two moving plates, and the bottom of the brush is in contact with the bottom inner wall of the metal casing.

[0021] Furthermore, the tensioning pulley is in close contact with the outer surface of the belt. The friction between them effectively alters the belt tension when the tensioning pulley is adjusted. Rotating the bolts on the front and rear sides of the metal casing causes the bolts on the closer side to push the two moving plates on the farther side, allowing the plates to slide within the inner cavity. This sliding motion of the moving plates displaces the rotating rod and the connected tensioning pulley, thus precisely adjusting the belt tension. The contact between the bottom of the brush and the inner wall of the bottom of the metal casing allows the brush to effectively scrape away scale as the belt moves. Stable belt tension ensures uniform brush movement speed, making the scale removal process more efficient and stable, thereby maintaining good heat transfer performance of the metal casing and contributing to the long-term stable and energy-saving operation of the energy-efficient heating device.

[0022] As a further description of the above technical solution:

[0023] The first rotating rod is externally rotatably connected to the inside left side of the two support plates, and the second rotating rod is externally rotatably connected to the inside right side of the two support plates.

[0024] Furthermore, during the belt drive process, the two support plates ensure that rotating rod one and rotating rod two always maintain a parallel and stable rotation state. In conjunction with the tensioning wheel, the belt is always in the optimal tension state during operation, creating favorable conditions for stable power transmission to the brush. This ensures that the brush can clean the scale on the bottom inner wall of the metal shell at a uniform speed and efficiently, maintaining the efficient operation of the energy-saving heating device.

[0025] As a further description of the above technical solution:

[0026] The steam pipes are provided with multiple steam holes inside, and the bottom of the sliding plate is rotatably connected to the top of the rotating frame.

[0027] Furthermore, when the rotating frame rotates, it can easily move the sliding plate up and down, allowing the square plates on both sides of the bottom of the sliding plate to smoothly connect or separate from the square opening inside the connecting plate, thereby achieving the fixing or disassembly of the heating copper tube.

[0028] As a further description of the above technical solution:

[0029] The interior of the metal casing has multiple elongated openings, and the outer side of the locking block engages with the inner wall of the elongated openings.

[0030] Furthermore, when it is necessary to disassemble the heating copper tube for maintenance or replacement, simply rotate the rotating frame in the opposite direction to disengage the locking block from the inner wall of the long slot. The sliding plate will then be unlocked and can move freely, causing the square plate to disengage from the square slot. This enables convenient disassembly of the heating copper tube, ensuring efficient maintenance of the device and maintaining the long-term stable operation of the energy-saving heating device.

[0031] This utility model has the following beneficial effects:

[0032] 1. In this utility model, after the motor is started, the motor drives the rotating rod to rotate, the rotating rod drives the belt to rotate, the belt drives the fixed plate to move, and the fixed plate drives the brush to move. When the brush contacts the bottom inner wall of the metal shell, the scale on the metal shell is cleaned, thereby restoring good heat transfer efficiency, enabling the energy-saving heating device to operate efficiently and truly achieve the energy-saving goal.

[0033] 2. In this utility model, by pressing the rotating frame, the rotating frame drives the telescopic rod to extend and retract, which in turn drives the spring to extend and retract. After the rotating frame is moved to the designated position, the sliding plate is disassembled from the connecting plate, thus enabling the disassembly of the heating copper tube. This allows for the timely detection and repair of minor corrosion problems in the copper tube, preventing it from developing into a serious leakage fault. This reduces the cost of large-scale maintenance or equipment replacement and improves the return on investment of the equipment. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

A fixing frame 9 is provided inside the metal shell 1, and the storage tank 10 is located inside the fixing frame 9.

[0044] Specifically, the various structures of the energy-saving heating device work closely together. The metal casing 1 provides protection and a mounting base, reducing heat loss; the motor 202 in the drive mechanism 2 drives the brush 207 to clean scale via a rotating rod and belt 205; the tensioning mechanism 3 adjusts the tension of the belt 205 to ensure power transmission; the support column 4 stabilizes the internal components; the bushing 5 buffers, protects, and enhances heat insulation; the steam pipe 6 and the heating copper pipe 7 generate and transport steam; the disassembly mechanism 8 facilitates maintenance of the heating copper pipe 7; and the fixing frame 9 fixes the storage tank 10, which is used to hold the material to be heated.

[0045] Reference Figure 3 The drive mechanism 2 includes a base 201, the front of which is fixedly connected to the rear left side of the metal casing 1. A motor 202 is fixedly connected to the top of the base 201, providing stable support for the motor 202 to ensure that the motor does not shake or shift during operation. A rotating rod 203 is fixedly connected to the drive end of the motor 202. The motor 202 serves as a power source, and its drive end is connected to the rotating rod 203. After starting, it outputs power to drive the rotating rod 203 to rotate, providing the power basis for subsequent operations such as cleaning scale. A rotating rod 204 is rotatably connected to the right side of the inside of the metal casing 1. A belt 205 is fitted around the outside of the rotating rod 203. The rotating rod 203 rotates under the drive of the motor 202, and the belt 205 drives the rotating rod 204 to rotate synchronously. The belt 205 is driven to rotate, and multiple fixing plates 206 are fixedly connected to the outside of the belt 205. Multiple brushes 207 are fixedly connected to the other side of the fixing plate 206. The belt 205 connects to rotating rod 1 203 and rotating rod 204. During the rotation, the multiple fixing plates 206 fixed on its surface drive the brushes 207 to move, thereby cleaning the bottom inner wall of the metal shell 1. The outside of rotating rod 1 203 is rotatably connected to the inside of the left side of the metal shell 1, and the inside right side of the belt 205 is sleeved on the outside of rotating rod 204. The fixing plate 206 converts the rotation of the belt 205 into the movement of the brushes 207. The brushes 207 contact the bottom inner wall of the metal shell 1 and remove scale through friction, restoring heat transfer efficiency and achieving energy saving.

[0046] Specifically, in the drive mechanism 2, the base 201 is fixed to the left rear of the metal shell 1, providing a stable support for the motor 202 and ensuring its stable operation; the motor 202, as a power source, drives the rotating rod 1 203 to rotate, and the rotating rod 1 203 drives the rotating rod 204 to rotate synchronously through the belt 205, realizing power transmission and conversion; the fixing plate 206 on the surface of the belt 205 drives the brush 207 to move, clean the bottom inner wall of the metal shell 1, remove scale to restore heat transfer efficiency, and finally achieve the purpose of energy saving.

[0047] Reference Figure 4The tensioning mechanism 3 includes two support plates 301, which provide mounting carriers for components such as the tensioning wheel 305 and ensure the stability of the entire tensioning mechanism 3. The bottom of the two support plates 301 is fixedly connected to the bottom inner wall of the metal shell 1. The support plates 301 have an inner cavity 302, and a movable plate 303 is slidably connected to the inner wall of the inner cavity 302. A rotating rod 304 is fixedly connected to the adjacent side of the two movable plates 303. The tensioning wheel 305 is rotatably connected to the outside of the rotating rod 304. Bolts 306 are threadedly connected to both the front and rear sides of the metal shell 1. The outside of the tensioning wheel 305 is in contact with the outside of the belt 205. The rotating rod 304 connects the movable plate 303 and the tensioning wheel 305, allowing the tensioning wheel 305 to rotate flexibly. The tensioning pulley 305 contacts the belt 205. By adjusting the position of the tensioning pulley 305, the belt 205 is always kept at a suitable tension to ensure stable power transmission. The adjacent sides of the two bolts 306 are in contact with the distant sides of the two moving plates 303. The moving plates 303 can slide in the inner cavity 302 under the action of the bolts 306. By adjusting their positions, the rotating rod 304 and the tensioning pulley 305 are moved, thereby adjusting the tension of the belt 205. The bottom of the brush 207 is in contact with the bottom inner wall of the metal shell 1. The external rotating rod 1 203 is rotatably connected to the inner left side of the two support plates 301, and the external rotating rod 204 is rotatably connected to the inner right side of the two support plates 301.

[0048] Specifically, the two support plates 301 of the tensioning mechanism 3 are firmly installed on the bottom inner wall of the metal shell 1, providing support for the entire mechanism. The inner cavity 302 inside the mechanism allows the moving plate 303 to slide flexibly. By rotating the bolts 306 on the front and rear sides of the metal shell 1, the moving plate 303 can be pushed, which in turn drives the tensioning wheel 305 to move via the rotating rod 304. This ensures that the tensioning wheel 305 flexibly fits the belt 205, accurately maintains the tension of the belt 205, and ensures that the power is stably transmitted from the motor 202 through the rotating rod and the belt 205 to the brush 207, helping the brush 207 to continuously and efficiently clean the scale on the bottom inner wall of the metal shell 1.

[0049] Reference Figure 5 and Figure 6The disassembly mechanism 8 includes multiple connecting plates 801. The tops of two connecting plates 801 are fixedly connected to the bottom sides of the heating copper tube 7. Square openings 802 are provided inside the connecting plates 801. Multiple cavities 803 are provided at the bottom of the metal outer shell 1. Sliding plates 804 are slidably connected to the inner walls of the cavities 803. Square plates 805 are fixedly connected to the bottom sides of the sliding plates 804. A rotating frame 806 is rotatably connected to the adjacent side of two square plates 805. A telescopic rod 807 is rotatably connected to the bottom of the sliding plates 804. The telescopic rod 807 cooperates with a spring 808. When the rotating frame 806 rotates, the telescopic rod 807 extends and retracts, and the spring 808 provides elastic force to assist the rotation of the rotating frame 806. It also acts as a buffer during disassembly. A spring 808 is sleeved on the outside of the telescopic rod 807. The top of the rotating frame 806... A locking block 809 is fixedly connected to the side of the rotating frame 806. The locking block 809 engages with the elongated opening inside the metal shell 1. When the locking block 809 engages with the elongated opening, the sliding plate 804 is fixed in position, thereby fixing the heating copper tube 7. When disassembly is required, the rotating frame 806 is rotated to disengage the locking block 809 from the elongated opening, thereby disassembling the heating copper tube 7. The rotating frame 806 connects the sliding plate 804 and the locking block 809. The rotation of the rotating frame 806 drives the sliding plate 804 to move up and down. At the same time, the locking block 809 engages with the elongated opening to lock the position of the sliding plate 804. The steam pipe 6 has multiple steam holes inside. The bottom of the sliding plate 804 is rotatably connected to the top of the rotating frame 806. The metal shell 1 has multiple elongated openings inside. The outside of the locking block 809 engages with the inner wall of the elongated opening.

[0050] Specifically, in the disassembly mechanism 8, the tops of multiple connecting plates 801 are fixed to both sides of the bottom of the heating copper tube 7. Their internal square openings 802 cooperate with the square plate 805 at the bottom of the sliding plate 804 inside the bottom cavity 803 of the metal casing 1, achieving initial positioning of the heating copper tube 7. The rotating frame 806 connects the sliding plate 804 and the locking block 809. When rotated, it drives the sliding plate 804 to move up and down. The locking block 809 engages or disengages from the elongated opening inside the metal casing 1, locking or unlocking the position of the sliding plate 804, thereby fixing or disassembling the heating copper tube 7. The telescopic rod 807 cooperates with the spring 808 to provide elastic assistance and buffering when the rotating frame 806 rotates, ensuring smooth disassembly operation, facilitating timely maintenance of the heating copper tube 7, and ensuring the normal operation of the device.

[0051] Working principle: When the water inside the metal casing 1 is heated, the motor 202 is started, which drives the rotating rod 203 to rotate. The rotating rod 203 drives the belt 205 to rotate, which in turn drives the rotating rod 204 to rotate. The belt 205 then moves the fixed plate 206, which in turn moves the brush 207. When the brush 207 contacts the bottom inner wall of the metal casing 1, it cleans the scale on the metal casing 1, thereby restoring good heat transfer efficiency and enabling the energy-saving heating device to operate efficiently, truly achieving the energy-saving goal.

[0052] When it is necessary to disassemble the heating copper tube 7, the rotating frame 806 is pressed first, which causes the telescopic rod 807 to extend and retract, and the telescopic rod 807 causes the spring 808 to extend and retract. After the rotating frame 806 is moved to the designated position, the sliding plate 804 is disassembled from the connecting plate 801, thus disassembling the heating copper tube 7. This allows for the timely detection and repair of minor corrosion problems in the copper tube, preventing them from developing into serious leakage faults. This reduces the cost of large-scale repair or replacement of equipment and improves the return on investment of the equipment.

[0053] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
