Description

Technical Field

[0001] The present invention relates to the technical field of heat exchange devices, and specifically to an energy-saving heat exchange heater. Background Art

[0002] The application of traditional heat exchangers in the fields of ocean engineering, ship power, etc. has long faced two major technical bottlenecks: First, the fixed baffle structure leads to a rigid flow field distribution, making it difficult to adapt to fluctuations in heat source parameters, easily forming local heat transfer dead zones, and causing attenuation of heat transfer efficiency; Second, high salinity, microorganisms, and suspended solids in seawater medium are likely to deposit on the pipe wall and in the flow channel, forming a fouling layer, significantly increasing the thermal resistance and exacerbating the corrosion risk. Existing improvement schemes mostly adopt static anti-scaling coatings or periodic chemical cleaning, but there are problems such as poor adaptability, high maintenance costs, and large shutdown losses.

[0003] In recent years, although technologies such as variable pitch baffles and vibration scale cleaning have developed, they mostly rely on independent drive units, and there are defects such as structural redundancy, increased energy consumption, and insufficient sealing reliability. For example, although traditional threaded tubes can enhance turbulence, it is difficult to clean the dirt accumulated in the threaded gaps; and dynamic seal designs often leak and fail under high-pressure seawater conditions. In addition, the dirt collection system mostly adopts an open filter structure, which has the risk of secondary pollution and low cleaning efficiency.

[0015] Compared with the prior art, the present invention provides an energy-saving heat exchange heater with the following beneficial effects: 1. The motor in the adjustment mechanism drives the bevel gear set, linking the threaded rod and the baffle to move horizontally, thereby realizing dynamic adjustment of the baffle spacing. The baffle spacing automatically adapts to changes in thermal fluid parameters such as temperature and flow, optimizes the distribution of seawater flow channels, eliminates local heat exchange dead zones, and combines the threads on the outer wall of the heat flow tube to enhance turbulence, so that low-temperature seawater spirally flushes the surface of the heat flow tube, improving heat exchange efficiency. The elliptical heat exchange tank reduces fluid resistance and cooperates with the dynamic adjustment function of the baffle to reduce the energy consumption required for pumping seawater. At the same time, efficient heat exchange shortens the residence time of the thermal fluid, reduces heating energy consumption, and achieves comprehensive energy-saving effects. When the baffle moves, the silicon carbide scraper synchronously scrapes the inner wall of the tank, and the second sleeve drives the rotating cleaning brush to clean the gap between the threads of the heat flow tube, realizing cleaning while running. Combined with the scale inhibitor spray system, a dual descaling mechanism of chemical softening and mechanical stripping is formed, which reduces the thermal resistance of fouling and maintains stable heat exchange performance for a long time.

[0016] 2. The waterproof sleeve cleaning brush and the vibration mechanism work in conjunction. The waterproof sleeve rotates to brush the baffle surface and the gap between the heat flow tube to peel off loose dirt. The rubber vibration plate intermittently knocks on the tank body to generate shock waves to shake off stubborn scale layers. The combination of the two covers more than 90% of the surface area. Through the dirt removal rate, the auger rod and the aggregate trough form a closed dirt treatment chain. The stripped scale residue settles to the aggregate trough with the fluid. The auger rod rotates and pushes it to the solenoid valve port to realize automatic collection and timed discharge of dirt. The stirring rod maintains the uniformity of the agent. The electromagnetic spray head rotates and sprays to make the scale inhibitor evenly cover the heat exchange surface, inhibiting microbial attachment and crystallization precipitation.

[0017] 3. The L-shaped bracket, eccentric cylinder, and spring vibration system form a low-power resonance unit. The eccentric rotation generates a periodic excitation force, which is transmitted to multiple rubber vibration plates through the sliding rod and pressure rod, forming global vibration of the tank body. The spring buffer design avoids overload, and the limit wheel guides to ensure stable amplitude. While removing scale, it protects the weld structure. The heat flow pipe and the second sleeve are thread-engaged, and with the elastic fitting design of the waterproof sleeve, dynamic sealing is achieved. Even during the adjustment of the baffle, zero leakage can still be maintained, and it is applicable to high-pressure (≤2.5 MPa) seawater conditions. Brief Description of the Drawings

Detailed Description of the Invention

[0020] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0021] Please refer to Figures 1 - 8 , an energy-saving heat exchange heater, including a heat exchange tank 1. The heat exchange tank 1 is designed in an oval shape. Two sets of symmetric cold flow pipes 2 are fixedly connected to both ends of the heat exchange tank 1. A heat flow pipe 3 is fixedly connected inside the heat exchange tank 1.

[0022] In this embodiment, the adjusting mechanism 4 includes a first bracket 41 fixedly connected to the heat exchange tank 1. A motor 42 is installed at the upper end of the first bracket 41. The output shaft of the motor 42 is fixedly connected to a first bevel gear 43. Two sets of symmetric second bevel gears 44 are meshed and connected to the outer side of the first bevel gear 43. One end of one of the two sets of second bevel gears 44 is fixedly connected to a threaded rod 45. The two ends of the threaded rod 45 are rotatably connected inside the heat exchange tank 1 through a rotating shaft.

[0023] Specifically, the first bracket 41 provides installation support for the motor 42 to ensure its stable operation. The motor 42 serves as a power source and drives the first bevel gear 43 to rotate through the output shaft. The first bevel gear 43 is meshed with two sets of symmetric second bevel gears 44 to split and transmit the power of the motor 42. One of the second bevel gears 44 drives the threaded rod 45 to rotate, providing power input for the subsequent adjustment of the distance between the baffle plates 6, making the threaded rod 45 a key transmission component connecting the power of the motor 42 and the movement of the baffle plate 6.

[0024] In this embodiment, a first sleeve 46 is rotatably connected to the outer side of the threaded rod 45. A first electric telescopic rod 47 is installed inside the first sleeve 46.

The output shaft of the second electric telescopic rod 49 is fixedly connected to the waterproof sleeve 412. One end of the waterproof sleeve 412 is fixedly connected to the third sleeve 411. A cleaning brush is arranged on the side of the waterproof sleeve 412 that is in contact with the baffle 6.

[0027] Please refer to Figures 1 - 8 , an energy-saving heat exchange heater, including a heat exchange tank 1. The heat exchange tank 1 is designed in an oval shape. Two symmetrically arranged cold flow pipes 2 are fixedly connected to both ends of the heat exchange tank 1. A heat flow pipe 3 is fixedly connected inside the heat exchange tank 1. Threads are arranged on the outer side of the heat flow pipe 3. An adjusting mechanism 4 for adjusting the impact flow of seawater and cleaning dirt is installed on the inner side of the heat exchange tank 1. A vibration mechanism 5 for vibrating and cleaning impurities is installed on the outer side of the heat exchange tank 1. A plurality of groups of symmetrically crossed baffles 6 are installed on the inner side of the heat exchange tank 1. The outer side of the baffle 6 is in contact with the inner wall of the heat exchange tank 1. A silicon carbide scraping strip 7 is fixedly connected to the outer side of the baffle 6.

[0028] In this embodiment, the adjusting mechanism 4 includes a first bracket 41 fixedly connected to the heat exchange tank 1. A motor 42 is installed at the upper end of the first bracket 41. The output shaft of the motor 42 is fixedly connected to a first bevel gear 43. Two symmetrically arranged second bevel gears 44 are meshed outside the first bevel gear 43. One end of a second bevel gear 44 in the two groups of second bevel gears 44 is fixedly connected to a threaded rod 45. Both ends of the threaded rod 45 are rotatably connected inside the heat exchange tank 1 through a rotating shaft.

[0029] Specifically, the first bracket 41 provides installation support for the motor 42 to ensure its stable operation. As the power source, the motor 42 drives the first bevel gear 43 to rotate through the output shaft. The first bevel gear 43 meshes with two groups of symmetric second bevel gears 44 to split and transmit the power of the motor 42. One group of second bevel gears 44 drives the threaded rod 45 to rotate, providing power input for the subsequent adjustment of the spacing of the baffle 6, making the threaded rod 45 a key transmission component connecting the power of the motor 42 and the movement of the baffle 6.

[0030] In this embodiment, a first sleeve 46 is rotatably connected to the outside of the threaded rod 45. A first electric telescopic rod 47 is installed inside the first sleeve 46. The output shaft of the first electric telescopic rod 47 is fixedly connected to an arc-shaped pressing plate 48. The upper end of the arc-shaped pressing plate 48 meshes with the threaded rod 45. A rubber pad is fixedly connected to the upper end of the arc-shaped pressing plate 48. The outside of the first sleeve 46 is fixedly connected to the baffle 6.

[0031] Specifically, the first sleeve 46 on the outside of the threaded rod 45 is fixedly connected to the baffle 6, playing a role in supporting and connecting the baffle 6. The first electric telescopic rod 47 controls the expansion and contraction of the arc-shaped pressing plate 48 through the output shaft. When the spacing of the baffle 6 needs to be adjusted, the first electric telescopic rod 47 extends, making the arc-shaped pressing plate 48 mesh with the threaded rod 45. Utilizing the characteristics of screw transmission, the rotational motion is converted into the axial movement of the first sleeve 46, thereby driving the baffle 6 to translate. The rubber pad at the upper end of the arc-shaped pressing plate 48 increases the friction with the threaded rod 45, ensuring the stability of the meshing, avoiding slipping, and guaranteeing the accuracy of the adjustment of the spacing of the baffle 6.

[0032] In this embodiment, the adjusting mechanism 4 further includes a plurality of second sleeves 410 threadedly connected to the heat flow pipe 3. The outside of the plurality of second sleeves 410 is respectively rotatably connected to a plurality of baffles 6. Both the front and rear ends of the second sleeve 410 are fixedly connected to a third sleeve 411. Two groups of symmetric second electric telescopic rods 49 are installed on the outside of the third sleeve 411. A waterproof sleeve 412 is arranged on the outside of the second electric telescopic rod 49. The output shaft of the second electric telescopic rod 49 is fixedly connected to the waterproof sleeve 412. One end of the waterproof sleeve 412 is fixedly connected to the third sleeve 411. A cleaning brush is arranged on the side of the waterproof sleeve 412 that fits the baffle 6.

[0033] Specifically, the second sleeve 410 threadedly connected to the hot flow tube 3 has its inner side threadedly engaged with the cold flow tube 2. When the deflector 6 moves, it rotates due to the threaded engagement relationship, thereby driving the third sleeve 411 on the outside to rotate. The second electric telescopic rod 49 on the outside of the third sleeve 411 controls the opening and contraction of the waterproof sleeve 412 through the output shaft, so that the waterproof sleeve 412 always fits the outside of the deflector 6. The cleaning brush on the side where the waterproof sleeve 412 fits the deflector 6, driven by the third sleeve 411, continuously scrubs the attachments on the surface of the deflector 6 and the thread gap of the hot flow tube 3, thereby achieving mechanical stripping of stubborn scale layers and cleaning dirt.

[0034] In this embodiment, the other end of the threaded rod 45 is fixedly connected to the first spur gear 413, the outer side of the first spur gear 413 is rotatably connected to the first chain 414, the inner side of the first chain 414 is rotatably connected to the second spur gear 415, and one end of the second spur gear 415 is rotatably connected to the heat exchange tank 1 through a rotating shaft.

[0035] Specifically, the first spur gear 413 at the other end of the threaded rod 45 is engaged with the first chain 414, transmitting the rotational power of the threaded rod 45 to the second spur gear 415. The second spur gear 415 is rotatably connected to the heat exchange tank 1 through a rotating shaft, and serves as an intermediate transmission component to further transmit power to the subsequent auger rod 416, so that the entire transmission system forms a coherent power transmission chain, providing power support for the collection and discharge of scale and residue in the aggregate trough 417.

[0036] In this embodiment, one end of the second spur gear 415 is rotatably connected to the auger rod 416 through a rotating shaft, and the outer side of the auger rod 416 is rotatably connected to the collection trough 417. The upper end of the collection trough 417 is fixedly connected to the heat exchange tank 1, and the lower end of the collection trough 417 is installed with two sets of symmetrical solenoid valves 418.

[0037] Specifically, the auger rod 416 at one end of the second spur gear 415 rotates in the aggregate trough 417, and utilizes the structural characteristics of the spiral blade to stir and push the scale and residue gathered in the aggregate trough 417, so that it moves toward the solenoid valve 418. The aggregate trough 417 is used to collect the scale and residue peeled off during the heat exchange process. Its upper end is fixedly connected to the heat exchange tank 1 to ensure structural stability. The two sets of symmetrical solenoid valves 418 at the lower end automatically open according to the control system instructions after the heat exchange cycle ends, and the scale and residue in the aggregate trough 417 are discharged, thereby realizing the self-cleaning function and avoiding manual intervention.

[0039] Specifically, the scale inhibitor liquid tank 419 on one side of the first bracket 41 is used to store the scale inhibitor. The stirring rod 420 is driven to rotate by another set of second bevel gears 44 to stir the scale inhibitor in the scale inhibitor liquid tank 419, prevent the agent from depositing, ensure that the scale inhibitor is in a uniformly mixed state before spraying, so that the subsequent electromagnetic spray head 422 can spray a better effect of scale inhibitor, better soften the water scale and inhibit the attachment of new scale.

[0040] In this embodiment, a third spur gear 421 is fixedly connected to the outer side of the stirring rod 420. A second chain 423 is rotatably connected to the outer side of the third spur gear 421. A fourth spur gear 424 is rotatably connected to the inner side of the second chain 423. An electromagnetic spray head 422 is fixedly connected to the inner side of the fourth spur gear 424. The outer side of the electromagnetic spray head 422 is rotatably connected to the heat exchange tank 1. The output inlet of the electromagnetic spray head 422 is rotatably connected to the scale inhibitor liquid tank 419 through a pipeline.

[0041] Specifically, the third spur gear 421 on the outer side of the stirring rod 420 meshes with the fourth spur gear 424 through the second chain 423 to transmit the rotational power of the stirring rod 420 to the electromagnetic spray head 422. The electromagnetic spray head 422 fixedly connected to the inner side of the fourth spur gear 424 rotates uniformly under the drive of power, and the scale inhibitor is directionally sprayed into the heat exchange tank 1 through a pipeline connected to the scale inhibitor liquid tank 419 at the output inlet. This design enables the scale inhibitor to be evenly diffused under the impact of seawater, improves the effect of the scale inhibitor, and realizes the functions of softening the water scale and inhibiting the attachment of microorganisms.

[0042] In this embodiment, the vibration mechanism 5 includes a second bracket 51. The second bracket 51 is designed in an L shape. The rear end of the second bracket 51 is fixedly connected to the heat exchange tank 1 through a fixture block. An eccentric cylinder 52 is provided at the front end of the second bracket 51. The rear end of the eccentric cylinder 52 is fixedly connected to the first spur gear 413 through a rotating shaft. A roller 53 is rotatably connected to the inner wall of the eccentric cylinder 52. The rear end of the roller 53 is rotatably connected to a mounting plate 54 through a rotating shaft. A sliding rod 55 is fixedly connected to one side of the mounting plate 54. The outer side of the sliding rod 55 is slidably connected to the second bracket 51. A spring 56 is provided on the outer side of the sliding rod 55. One end of the spring 56 is fixedly connected to the mounting plate 54, and the other end of the spring 56 is fixedly connected to the second bracket 51. A limiting rod 57 is fixedly connected to one side of the mounting plate 54. The outer side of the limiting rod 57 is slidably connected to the second bracket 51.

[0043] Specifically, the second support 51 of the vibration mechanism 5 is designed in an L shape. The rear end is fixedly connected to the heat exchange tank 1 through a clamping block, providing a stable installation foundation for the entire vibration mechanism 5. The eccentric cylinder 52 at the front end is fixedly connected to the first straight gear 413 and rotates with the first straight gear 413. Using its eccentric structure, it generates centrifugal force to push the roller 53 on the inner wall to move reciprocally. The roller 53 is connected to the mounting plate 54 through a rotating shaft, converting the rotational motion of the eccentric cylinder 52 into the linear motion of the mounting plate 54. The sliding rod 55 on one side of the mounting plate 54 slides within the second support 51, and the spring 56 on the outside compresses and expands when the sliding rod 55 moves, storing and releasing elastic potential energy to form a periodic vibration excitation. The limiting rod 57 is slidably connected to the second support 51 to ensure that the sliding rod 55 moves in a straight line, avoiding deviation and ensuring the stability and reliability of the vibration mechanism 5.

[0044] In this embodiment, a limiting plate 58 is fixedly connected to one end of the sliding rod 55, a pressing rod 59 is fixedly connected to the other end of the limiting plate 58, multiple groups of rubber vibration plates 510 are fixedly connected to the outside of the pressing rod 59, and a limiting wheel 511 is rotatably connected to the other end of the pressing rod 59. The limiting wheel 511 is slidably connected to the inside of the heat exchange tank 1.

[0045] Specifically, the limiting plate 58 at one end of the sliding rod 55 prevents the sliding rod 55 from sliding out of the second support 51, playing a limiting role. The pressing rod 59 at the other end is connected to multiple groups of rubber vibration plates 510 and performs an axial movement driven by the sliding rod 55, causing the rubber vibration plates 510 to strike the outside of the heat exchange tank 1, generating vibration waves and conducting them to the inner wall to shake off stubbornly attached scale layers. The limiting wheel 511 at the other end of the pressing rod 59 slides inside the heat exchange tank 1, providing support and guidance for the pressing rod 59 to ensure its stable movement trajectory, avoiding the off-load failure of the vibration mechanism 5 and making the vibration scale removal effect more uniform and effective.

[0046] Working principle: During use, low-temperature seawater symmetrically flows into the elliptical heat exchange tank 1 through the cold flow pipe 2 and spirally flushes the outer wall of the heat flow pipe 3 along the cross-flow channels formed by the baffle plates 6; high-temperature fluid is conveyed inside the heat flow pipe 3, and the threaded structure on its surface increases the degree of turbulence and strengthens the convective heat transfer inside and outside the pipe. In the initial state, multiple groups of symmetrically crossed baffle plates 6 are tightly attached to the inner wall of the tank through the silicon carbide scraping strips 7 on the outside. The initial spacing is preset by the adjusting mechanism 4 to form a stable turbulent flow field, ensuring that the seawater evenly covers the surface of the heat flow pipe 3. When the temperature or flow rate of the hot fluid changes, the control system starts the motor 42 on the first bracket 41, and its output shaft drives two groups of symmetric second bevel gears 44 through the first bevel gear 43; one group of second bevel gears 44 drives the threaded rod 45 to rotate. At this time, the first electric telescopic rod 47 extends so that the arc-shaped pressing plate 48 is threadedly engaged with the threaded rod 45, and through screw drive, it pushes the first sleeve 46 to move axially, thereby driving the entire group of baffle plates 6 to translate, realizing the synchronous adjustment of the spacing of multiple groups of baffle plates 6. When the seawater flows through the variable-spacing flow channel, the flow rate and impact angle are dynamically adapted to the parameters of the hot fluid, avoiding local heat exchange dead zones. The other group of second bevel gears 44 drives the stirring rod 420 to rotate, stirring the scale inhibitor liquid tank 419 to prevent the precipitation of the agent; During the movement of the baffle plate 6, the silicon carbide scraping strip 7 on the outside synchronously scrapes the scale on the inner wall of the tank; at the same time, the second sleeve 410 threadedly connected to the heat flow pipe 3 translates with the baffle plate 6 and rotates automatically due to the threaded engagement relationship, driving the second electric telescopic rod 49 and the waterproof sleeve 412 outside the third sleeve 411 to rotate around the heat flow pipe 3. The cleaning brush on one side of the waterproof sleeve 412 continuously brushes the surface of the baffle plate 6, and the attached substances in the thread gap of the heat flow pipe 3 are cleaned by the rotational friction of the third sleeve 411, realizing the mechanical peeling of stubborn scale layers; The third spur gear 421 at the end of the stirring rod 420 drives the fourth spur gear 424 through the second chain 423, making the electromagnetic spray head 422 rotate at a constant speed and spray the scale inhibitor in a directional manner. The agent is evenly diffused under the impact of the seawater, softening the formed scale and inhibiting the adhesion of new scale. With the guiding effect of the elliptical tank body, the loose scale residues converge towards the bottom aggregate tank 417. The first spur gear 413 at the end of the threaded rod 45 drives the second spur gear 415 through the first chain 414, driving the auger rod ## The first spur gear 413 synchronously drives the eccentric cylinder 52 to rotate, and its eccentric contour pushes the roller 53 to reciprocate. The slide bar 55 is driven to slide in the second bracket 51 through the mounting plate 54, compressing the spring 56 to store elastic potential energy, and the linear movement of the slide bar 55 is maintained by the limiting rod 57. When the eccentric cylinder 52 rotates past the critical point, the tension of the spring 56 causes the roller 53 to remain in contact with the inner wall of the eccentric cylinder 52, forming a periodic vibration excitation. The limiting plate 58 at the end of the slide bar 55 drives the pressure bar 59 to move axially, causing multiple rubber vibration plates 510 to intermittently strike the outer side of the tank body. The vibration waves are evenly conducted to the inner wall through the elliptical shell, shaking off stubbornly adhering scale layers. Moreover, using the rubber vibration plates 510 to intermittently strike the outer wall of the tank body will not cause damage to the welds of the tank body. The limiting wheel 511 slides along the inner side of the heat exchange tank 1 to ensure the stable movement track of the pressure bar 59 and prevent the vibration mechanism 5 from failing due to eccentric loading.
