Description

Technical Field

[0001] The present invention relates to the technical field of heat exchanger descaling, and in particular to an anti-scaling heat exchanger with a descaling function. Background Art

[0002] Large, single-pass modular heat exchangers are devices used for heat transfer, without internal baffles. By transferring heat from one fluid to another, they achieve efficient energy utilization or process temperature control. They are key equipment in numerous industries, including chemical, petroleum, power, refrigeration, HVAC, and food processing.

[0003] When a large single-pass module heat exchanger is put into operation and continues to work for a period of time, scale will inevitably adhere to the outer surface of its internal pipes. The accumulation of this scale will change the heat transfer characteristics of the pipe surface, thereby affecting the overall heat exchange efficiency of the heat exchanger.

[0004] Therefore, it is necessary to descale the pipes inside the heat exchanger of the large single-return module. The existing descaling method is to use an ultrasonic descaling device to descale the pipe surface. Generally, the method of using an ultrasonic descaling device to descale the pipe surface is divided into contact and non-contact. Although the contact descaling efficiency is high, the vibration end of the ultrasonic descaling device needs to directly contact the pipe and be rigidly connected to the pipe. This high-frequency vibration will cause certain damage to the pipe and the connection between the pipe and the heat exchanger. However, the non-contact descaling efficiency is low. When using non-contact descaling, the ultrasonic descaling device is fixedly installed on the outside of the heat exchanger, and its vibration head is located inside the heat exchanger. The ultrasonic wave is transmitted to the scale layer through the fluid medium. The ultrasonic wave produces a cavitation effect in the fluid, indirectly acting on the scale layer to make it fall off, but the descaling efficiency is low.

[0005] Therefore, it is necessary to provide an anti-scaling heat exchanger with a descaling function to solve the above technical problems. Summary of the Invention

[0006] In order to solve the above technical problems, the present invention provides an anti-scaling heat exchanger with a descaling function.

[0007] The present invention provides an anti-scaling heat exchanger with a descaling function, which includes a heat exchanger and a pipeline, and the pipeline is located inside the heat exchanger. Frames are provided on both sides of the heat exchanger, and the frame and the heat exchanger are interconnected. A transmission mechanism is linearly provided inside the frame, and the movable end of the transmission mechanism is connected to a mounting plate.

The ultrasonic descaling mechanism is wrapped around the periphery of the pipeline, and a descaling promotion mechanism for assisting the ultrasonic descaling mechanism in uniform descaling is rotatably provided at one end of the mounting plate near the ultrasonic descaling mechanism, and the elastic end of the descaling promotion mechanism is in contact with the outer wall of the pipeline.

[0008] Preferably, the transmission mechanism includes a motor, a screw, a moving block, and a guide rod.

[0009] Preferably, the ultrasonic descaling mechanism includes an ultrasonic descaling device, an arc-shaped plate 1, and a vibrating body. The surface of the mounting plate is provided with an ultrasonic descaling device. One end of the ultrasonic descaling device is fixedly connected to the arc-shaped plate 1. The inner arc surface of the arc-shaped plate 1 is connected to multiple vibrating bodies, and the vibrating bodies are sleeved on the outside of the pipe.

[0010] Preferably, the vibrating body includes a vibrating ring and a vibrating rod, the inner arc surface of the arc-shaped plate 1 is connected to the vibrating ring, and the inner circular surface of the vibrating ring is fixedly connected to a plurality of vibrating rods.

[0011] Preferably, the promotion mechanism includes a connecting rod, an arc-shaped plate 2, and a knocking assembly. One end of the mounting plate is fixedly connected to the connecting rod, one end of the connecting rod is fixedly connected to the arc-shaped plate 2, and the inner arc surface of the arc-shaped plate 2 is fixedly connected to multiple knocking assemblies. The knocking assembly is sleeved on the outside of the pipe, and the knocking end of the knocking assembly is in contact with the outer wall of the pipe.

[0012] Preferably, the knocking assembly includes a fixed sleeve, a rotating sleeve, a driving blade, a sliding rod, and a spring.

[0013] Compared with related technologies, the anti-scaling heat exchanger with a descaling function provided by the present invention has the following beneficial effects: 1. The ultrasonic descaling mechanism uses ultrasonic technology to accurately transmit high-frequency vibrations to its descaling end. Since the descaling end adopts a unique wrapping design, it can fit tightly to each pipe, so that the vibration source is extremely close to the scale layer on the pipe surface. This close-range vibration transmission method greatly enhances the descaling effect and ensures the efficiency of the descaling operation. At the same time, the wrapping design also ensures the uniformity of descaling, avoiding the problem of incomplete local descaling that may occur in traditional descaling methods. Driven continuously by the transmission mechanism, the ultrasonic descaling mechanism can perform comprehensive and dead-angle descaling operations along the pipeline.

[0014] 2. Driven by the transmission mechanism, the descaling mechanism also moves synchronously on the pipe surface. The fan blade structure cleverly arranged on the surface of the descaling mechanism generates corresponding power, causing its rotating part to rotate during movement, driving the elastic part of the descaling mechanism to slide on the scale layer on the pipe surface. Due to the uneven surface of the scale layer, the elastic part will continuously jump during the sliding process, producing an elastic knocking and plucking effect on the scale layer. This elastic knocking and plucking effect can effectively promote the shedding of the scale layer and significantly improve the descaling efficiency of the ultrasonic descaling mechanism.

[0017] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0018] Please refer to Figures 1 to 7 A scale-resistant heat exchanger with a scale removal function includes a heat exchanger 1 and a pipeline 7, and the pipeline 7 is located inside the heat exchanger 1. A frame 2 is provided on both sides of the heat exchanger 1. The frame 2 and the heat exchanger 1 are connected to each other. A transmission mechanism 3 is linearly provided inside the frame 2. The movable end of the transmission mechanism 3 is connected to a mounting plate 4. One end of the mounting plate 4 is fixedly provided with an ultrasonic scale removal mechanism 5 for uniformly descaling the outside of the pipeline 7 in an arc shape. The ultrasonic scale removal mechanism 5 is wrapped around the periphery of the pipeline 7. One end of the mounting plate 4 is close to the ultrasonic scale removal mechanism 5 and is rotatably provided with a descaling promotion mechanism 6 for assisting the ultrasonic scale removal mechanism 5 in uniform descaling, and the elastic end of the descaling promotion mechanism 6 is in contact with the outer wall of the pipeline 7.

[0019] During the specific implementation process, when it is necessary to remove stubborn scale on the surface of the internal pipe 7 of the heat exchanger 1, the user can start the transmission mechanism 3. Under the drive of the transmission mechanism 3, the mounting plate 4 starts to move in a predetermined direction, thereby driving the ultrasonic descaling mechanism 5 and the descaling promotion mechanism 6 to move synchronously along the axial direction of the pipe 7.

[0020] The ultrasonic descaling mechanism 5 uses ultrasonic technology to accurately transmit high-frequency vibrations to its descaling end. Since the descaling end adopts a unique wrapping design, it can fit tightly to each pipe 7, so that the vibration source is extremely close to the scale layer on the surface of the pipe 7. This close-range vibration transmission method greatly enhances the descaling effect and ensures the high efficiency of the descaling operation. At the same time, the wrapping design also ensures the uniformity of descaling and avoids the problem of incomplete local descaling that may occur in traditional descaling methods. Under the continuous drive of the transmission mechanism 3, the ultrasonic descaling mechanism 5 can perform comprehensive and dead-angle descaling operations along the pipe 7.

[0021] At the same time, driven by the transmission mechanism 3, the descaling mechanism 6 also moves synchronously on the surface of the pipe 7. The fan blade structure is cleverly set on the surface of the descaling mechanism 6. The fan blade structure generates corresponding power, causing its rotating part to rotate during the movement, driving the elastic part of the descaling mechanism 6 to slide on the scale layer on the surface of the pipe 7. Due to the uneven surface of the scale layer, the elastic part will continue to jump during the sliding process, producing an elastic knocking and plucking effect on the scale layer. This elastic knocking and plucking effect can effectively promote the shedding of the scale layer and significantly improve the descaling efficiency of the ultrasonic descaling mechanism 5.

[0022] Under the coordinated action of the transmission mechanism 3, the ultrasonic descaling mechanism 5 and the descaling promotion mechanism 6, the descaling operation of the internal pipe 7 of the heat exchanger 1 can be completed efficiently and comprehensively, providing a strong guarantee for the stable operation and efficient heat exchange of the heat exchanger 1.

[0023] refer to Figure 2 and Figure 3 As shown, the transmission mechanism 3 includes a motor 31, a screw rod 32, a moving block 33, and a guide rod 34. The motor 31 is installed at one end of the frame 2, and the output end of the motor 31 passes through the inner wall of the frame 2 and is fixedly connected to the screw rod 32. One end of the screw rod 32 is rotatably connected to the inner wall of the frame 2, and the inside of the frame 2 is fixedly connected to the guide rod 34. The surface of the screw rod 32 is threadedly connected to the moving block 33. The guide rod 34 passes through the moving block 33 and is slidably connected to the moving block 33. The moving block 33 is fixedly connected to the mounting plate 4.

[0024] It should be noted that when descaling pipe 7 is to be performed, the user activates motor 31. Upon receiving the activation signal, the power output shaft within motor 31 begins to rotate at high speed, thereby driving the connected screw 32 to rotate synchronously. Driven by motor 31, screw 32 rotates at a stable speed and torque.

[0025] As the screw shaft 32 rotates, the threaded movable block 33, influenced by the force of the threads, begins to move along the screw shaft 32. Simultaneously, the movable block 33 closely adheres to the guide rod 34 and slides smoothly along its surface. Like a precise navigator, the guide rod 34 provides stable guidance for the movable block 33, ensuring that it does not deviate or wobble during movement.

[0026] Under the precise guidance of the guide rod 34, the moving block 33 moves along a predetermined path, driving the mounting plate 4 to move smoothly along the axial direction of the pipe 7. The mounting plate 4 serves as a supporting platform for the ultrasonic descaling mechanism 5 and the descaling promotion mechanism 6. Its movement directly drives these two mechanisms to move synchronously along the axial direction of the pipe 7.

[0027] In this way, the ultrasonic descaling mechanism 5 and the descaling promotion mechanism 6 can perform all-round and dead-angle descaling operations on the surface of the entire pipeline 7 during the movement, ensuring that their descaling effect can completely cover every area of the pipeline 7, thereby effectively improving the descaling efficiency and effect.

[0028] refer to Figure 3 and Figure 4 as well as Figure 5 As shown, the ultrasonic descaling mechanism 5 includes an ultrasonic descaling device 51, an arc-shaped plate 52, and a vibrating body 53. The surface of the mounting plate 4 is provided with the ultrasonic descaling device 51, one end of the ultrasonic descaling device 51 is fixedly connected to the arc-shaped plate 52, and the inner arc surface of the arc-shaped plate 52 is connected to multiple vibrating bodies 53, and the vibrating bodies 53 are sleeved on the outside of the pipe 7.

[0029] It should be noted that when the transmission mechanism 3 drives the mounting plate 4 to move, it will drive the ultrasonic descaling device 51 to move, thereby driving the arc plate 1 52 to move. Since the arc plate 1 52 moves, the vibrating body 53 is driven to move on the surface of the pipe 7. The vibration of the ultrasonic descaling device 51 can be transmitted to the vibrating body 53 through the arc plate 1 52. Since the vibrating body 53 wraps the pipe 7 and vibrates, the vibrating body 53 can ensure the uniformity of descaling, avoiding the problem of incomplete local descaling that may occur in traditional descaling methods.

[0030] refer to Figure 7 As shown, the vibrating body 53 includes a vibrating ring 531 and vibrating rods 532 . The inner arc surface of the arc-shaped plate 1 52 is connected to the vibrating ring 531 , and the inner circular surface of the vibrating ring 531 is fixedly connected to a plurality of vibrating rods 532 .

[0031] It should be noted that the vibration ring 531 drives the vibration rods 532 to move on the surface of the pipe 7, and the vibration ring 531 drives the multiple vibration rods 532 to vibrate, and the vibration rods 532 are used to loosen the scale layer on the surface of the pipe 7, or even make it fall off.

[0032] refer to Figure 5 and Figure 6 As shown, the promotion mechanism 6 includes a connecting rod 61, an arc plate 2 62, and a knocking assembly 63. One end of the mounting plate 4 is fixedly connected to the connecting rod 61, one end of the connecting rod 61 is fixedly connected to the arc plate 2 62, and the inner arc surface of the arc plate 2 62 is fixedly connected to multiple knocking assemblies 63. The knocking assembly 63 is sleeved on the outside of the pipe 7, and the knocking end of the knocking assembly 63 is in contact with the outer wall of the pipe 7.

[0033] It should be noted that: when the mounting plate 4 moves, the connecting rod 61 is driven to move, and the arc plate 2 62 is driven to move, and the knocking component 63 is driven to slide on the surface of the pipe 7. Since the rotating part of the knocking component 63 is provided with fan blades, when the knocking component 63 moves, the fan blades provided on the surface of the rotating part can make the rotating part rotate. The rotating part of the knocking component 63 drives its elastic part to move on the outer wall of the pipe 7 and rotate at the same time. Since the scale layer on the outer wall of the pipe 7 is uneven, the elastic part of the knocking component 63 can jump on the surface of the scale layer, thereby knocking and plucking the scale layer, thereby increasing the speed of scale shedding.

[0034] refer to Figure 6As shown, the knocking assembly 63 includes a fixed sleeve 631, a rotating sleeve 632, a driving blade 633, a sliding rod 634, and a spring 635. The inner arc surface of the arc plate 2 62 is fixedly connected to the fixed sleeve 631, and the rotating sleeve 632 is rotatably provided inside the fixed sleeve 631. The outer circular surface of the rotating sleeve 632 is circularly provided with multiple driving blades 633. The surface of the rotating sleeve 632 is slidably connected to multiple sliding rods 634. The surface of the sliding rod 634 is wrapped with a spring 635. One end of the spring 635 is fixedly connected to the handle end of the sliding rod 634, and the other end of the spring 635 is fixedly connected to the surface of the rotating sleeve 632.

[0035] It should be noted that when the arc-shaped plate 2 62 starts to move, it pulls the fixed sleeve 631 to move synchronously. During the movement of the fixed sleeve 631, the driving blades 633 begin to play a key role. These driving blades 633 generate power under the push of the medium, thereby driving the rotating sleeve 632 to rotate smoothly and stably relative to the fixed sleeve 631.

[0036] The rotation of the rotating sleeve 632 drives the multiple sliding rods 634 connected thereto to rotate synchronously. At this time, the sliding rods 634 not only move along the surface of the pipe 7 with the fixed sleeve 631, but also rotate due to the rotation of the rotating sleeve 632, forming a unique composite motion mode.

[0037] On the surface of the scale layer, this composite motion mode demonstrates a strong potential for scale removal. Since the surface of the scale layer is uneven and filled with various tiny bumps and depressions, the sliding rod 634 will constantly collide and squeeze with these uneven surfaces during the movement and rotation process. With the perfect elastic force of the spring 635, the sliding rod 634 jumps on the surface of the scale layer.

[0038] The sliding rod 634 uses its knocking end to knock the scale layer forcefully and move it skillfully. This knocking and moving penetrates deep into the scale layer. It cooperates with the ultrasonic descaling mechanism 5 to form a powerful descaling force, which greatly accelerates the shedding speed of the scale layer, allowing the surface of the pipeline 7 to quickly return to cleanliness, ensuring the normal operation and high efficiency of the pipeline 7 system.

[0039] refer to Figure 6 As shown, the striking end of the sliding rod 634 is arranged in an arc shape, and a non-slip rubber sleeve is provided on the surface.

[0040] It should be noted that by providing an anti-slip rubber sleeve on the knocking end of the sliding rod 634, the friction between the knocking end of the sliding rod 634 and the scale layer can be increased, thereby improving the knocking end of the sliding rod 634's ability to peel off the scale layer, thereby accelerating the shedding speed of the scale layer.

[0041] The working principle of the anti-scaling heat exchanger with a descaling function provided by the present invention is as follows: the user first starts the motor 31 and the ultrasonic descaling device 51. Due to the rotation of the output end of the motor 31, the screw 32 is driven to rotate, and then the moving block 33 and the mounting plate 4 are driven to move along the axial direction of the pipe 7 under the guidance of the guide rod 34, so that the ultrasonic descaling mechanism 5 and the descaling mechanism 6 are moved along the axial direction of the pipe 7. At the same time, the vibration of the ultrasonic descaling device 51 passes through the arc plate 1 52 and is transmitted to the vibration ring 531 and the vibration rod 532. The vibration of the vibration rod 532 is used to loosen and remove the scale on the surface of the pipe 7. Since the vibration rod 532 wraps the pipe 7, The pipeline 7 can be descaled more efficiently and evenly. At the same time, the mounting plate 4 drives the connecting rod 61, the arc-shaped plate 2 62, and the knocking assembly 63 to move. The knocking assembly 63 drives the rotating sleeve 632 to rotate by driving the blade 633, thereby driving the sliding rod 634 to move and rotate on the uneven scale surface. The elastic force of the spring 635 causes the sliding rod 634 to jump on the uneven scale surface. On the one hand, the knocking effect generated by the jumping is used to accelerate the shedding of the scale. On the other hand, the anti-slip rubber sleeve is used to peel off the uneven scale to increase the shedding speed of the scale loosened by the ultrasonic descaling device 51.
