Description

Technical Field

[0001] The present invention belongs to the technical field of heat exchangers, and specifically relates to an intelligent chemical heat exchanger with a drainage structure. Background Art

[0002] In the process of chemical production, as a key device for realizing effective heat transfer, recovery, and utilization, the performance of a heat exchanger directly affects production efficiency and energy consumption. Existing chemical heat exchangers generally have problems such as low heat transfer efficiency, easy fouling and blockage, and poor adaptability to changes in working conditions. On the one hand, the layout of the heat exchange chamber and the fluid guiding method of traditional heat exchangers are single, resulting in uneven fluid distribution and inability to fully utilize the heat exchange area, leading to a large amount of heat loss. At the same time, during long-term operation, impurities contained in the fluid, such as particulate deposits and chemical crystals, are extremely likely to deposit on the heat exchange surface, forming a fouling layer. To address this problem, some heat exchangers use a scraping method to remove fouling. However, due to the limitations of the structure and operation mode of ordinary scrapers, it is difficult to fully cover the heat exchange surface. In the corners, edges, and complex structure parts of the heat exchange chamber, the scrapers cannot reach, resulting in dead corners in fouling cleaning. Over time, the fouling in these dead corners accumulates, not only reducing the heat transfer efficiency but also causing equipment failures such as pipeline perforation and leakage due to the corrosion of the fouling, greatly increasing the maintenance cost.

[0003] In view of this, the present invention is specifically proposed. Summary of the Invention

[0018] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention.

[0019] Example 1: Figures 1 to 7As shown in the figure, an intelligent chemical heat exchanger with a drainage structure includes a heat exchange cover 1. Inside the heat exchange cover 1, a partition plate 11 is installed for dividing its heat exchange chamber. There is a communicating heat exchange interlayer 12 between the partition plate 11 and the inner part of the heat exchange cover 1. An inlet pipe 2 is installed inside the heat exchange cover 1, and a notch 243 connecting different heat exchange chambers is opened on its surface. A cavity-changing component is installed inside the inlet pipe 2. The cavity-changing component includes a turbulent flow fan blade 23 and two sealing blocks 241 that are coaxially connected and used to seal the corresponding notch 243. Opposite-direction inner grooves 242 are opened on the two sealing blocks 241. A compression component that slides along the inner groove to change the size of the heat exchange chamber is installed inside the heat exchange cover 1. A drainage component is installed on the partition plate 11. The drainage component includes a drainage plate 4 that is rotatably installed on the partition plate 11 and is in an arc state. Drainage holes 42 are opened on the surface of the drainage plate 4, and the inner cavity of the drainage plate 4 communicates with the heat exchange interlayer 12. On the rotation center of the drainage plate 4, there is a push plate 44 located in different heat exchange chambers. A sealing component for sealing the discharge port of the corresponding heat exchange chamber is arranged on the surface of the push plate 44.

[0020] As Figures 1 to 7 shown, in the specific implementation, a connecting plate 13 is installed on the outer shell of the heat exchange cover 1. A positioning plate 131 is installed at the end of the connecting plate 13, and the positioning plate 131 forms a 90-degree angle with the connecting plate 13. Positioning holes 132 for fixed installation are opened on the surface of the positioning plate 131, and the positioning holes 132 are through holes. Reinforcing ribs 133 are installed on the surface of the positioning plate 131, and the reinforcing ribs 133 are connected to the connecting plate 13. The reinforcing ribs 133 are triangular. This design significantly enhances the stability of the connection between the positioning plate 131 and the connecting plate 13, ensuring that the equipment can withstand greater external forces after installation, reducing the risk of equipment loosening caused by factors such as vibration and impact, and extending the service life of the equipment.

[0021] As Figures 1 to 7 shown, further, the partition plate 11 is placed at the central position of the heat exchange cover 1. A first heat exchange chamber 111 is formed between the upper part of the partition plate 11 and the inner wall of the heat exchange cover 1, and a second heat exchange chamber 112 is formed between the lower part of the partition plate 11 and the inner wall of the heat exchange cover 1. Fixing blocks 121 for strengthening the heat exchange interlayer 12 are installed inside the heat exchange interlayer 12 to improve its stability. An input pipe 122 is installed on one side wall of the heat exchange cover 1, and an output end 123 is installed on the other side wall of the heat exchange cover 1. The input pipe 122 and the output end 123 are interconnected. The above structure discloses the specific structure of the heat exchange cover 1.

[0022] Example 2: Different from Example 1 in this example: As Figures 1 to 7As shown in the figure, a mounting plate 21 is welded to the outer wall of the liquid inlet pipe 2. The mounting plate 21 is in contact with the side wall of the heat exchange cover 1, and a locking bolt is installed between the mounting plate 21 and the side wall of the heat exchange cover 1. This installation method makes the connection between the liquid inlet pipe 2 and the heat exchange cover 1 more firm, and at the same time facilitates the disassembly and maintenance of the equipment. A connecting flange 22 is installed at the top of the liquid inlet pipe 2, and through holes are provided on the connecting flange 22. It is convenient to connect with other pipes, improving the versatility of the equipment.

[0023] As Figures 1 to 7 shown, in the specific implementation, an outer cover 231 is provided on the liquid inlet pipe 2. The diameter of the outer cover 231 is larger than that of the liquid inlet pipe 2. The turbulence fan blade 23 is placed in the outer cover 231. A synchronous shaft 232 is installed at the rotation center of the turbulence fan blade 23. A cross bracket 233 is movably installed on the side wall of the synchronous shaft 232. The cross bracket 233 is installed on the side wall of the liquid inlet pipe 2. A transmission shaft 24 is installed at the end of the synchronous shaft 232. The transmission shaft 24 is connected to the rotation centers of the two sealing blocks 241. During the process of transporting the heat exchange liquid, the heat exchange liquid can flow in the liquid inlet pipe 2, impact the turbulence fan blade 23, and then drive the turbulence fan blade 23 to start rotating. While the turbulence fan blade 23 is rotating, the synchronous shaft 232 at the rotation center rotates on the cross bracket 233, and the synchronous shaft 232 drives the transmission shaft 24 at the bottom to rotate. At this time, the transmission shaft 24 at the bottom can drive the two sealing blocks 241 to rotate.

[0024] As Figures 1 to 7 shown, further, the compression assembly includes a compression plate 3. The compression plate 3 is slidably arranged in the corresponding first heat exchange chamber 111 and second heat exchange chamber 112. A top rod 31 is installed on the compression plate 3. The top rod 31 movably penetrates the side wall of the heat exchange cover 1, and the end of the top rod 31 is slidably connected to the side wall of the sealing block 241. A power storage rod 324 is installed on the compression plate 3. The power storage rod 324 movably penetrates the heat exchange cover 1, and the end of the power storage rod 324 is movably inserted into a power storage cover 32 installed on the side wall of the heat exchange cover 1. A fixing plate 321 is installed on the side wall of the power storage cover 32, and the fixing plate 321 is installed on the side wall of the heat exchange cover 1. A sliding plate 322 is slidably arranged inside the power storage cover 32. One end of the sliding plate 322 is connected to the power storage rod 324, and a power storage spring 323 is clamped between the other end of the sliding plate 322 and the side wall of the power storage cover 32. The compression direction of the power storage spring 323 and the moving direction of the power storage rod 324 are on the same straight line. When the top rod 31 is in contact with the inner groove 242, the top rod 31 moves to the right. The top rod 31 can drive the compression plate 3 to move to the right, thereby compressing the space of the first heat exchange chamber 111, enabling the water body to fill the entire first heat exchange chamber 111, and thus making the heat exchange more sufficient. Among them, the power storage spring 323 in the power storage cover 32 drives the power storage rod 324 to always have a tendency to move to the right, and the top rod 31 is always in contact with the side wall of the sealing block 241.

[0025] Embodiment 3: The difference from Embodiment 2 in this embodiment is as follows: As Figures 1 to 7 shown, a connecting pipe 411 is installed on the drainage plate 4. The connecting pipe 411 is connected to a cavity 412 formed inside the drainage plate 4. A hollow shaft 41 is installed at the bottom of the connecting pipe 411. The hollow shaft 41 is communicated with the connecting pipe 411 and the heat exchange interlayer 12. The hollow shaft 41 is rotatably installed in an installation groove 431 formed on the surface of the partition plate 11. A sealing plate 43 is installed on the side wall of the drainage plate 4. The size of the sealing plate 43 is adapted to the size of the installation groove 431. The sealing plate 43 and the installation groove 431 are adapted to achieve a sealing effect. The side wall of the hollow shaft 41 is connected to a push plate 44. A bending groove 46 is formed on the inner wall of the heat exchange cover 1 corresponding to the push plate 44. The bending groove 46 increases the heat exchange area.

[0026] As Figures 1 to 7 shown, in the specific implementation, the sealing component includes a push rod 45 that slides horizontally. A limit seat 451 is slidably arranged on the side wall of the push rod 45, and the limit seat 451 is installed on the partition plate 11. A sliding rod 452 is installed at the end of the push rod 45. A pair of U-shaped frames 441 are installed on the side wall of the push plate 44. A gap 442 is left between the pair of U-shaped frames 441. The push rod 45 passes through the gap 442. A sliding groove 443 is formed between the pair of U-shaped frames 441 and the side wall of the push plate 44. The sliding rod 452 is slidably arranged in the sliding groove 443. The push rod 45 passes through the side wall of the heat exchange cover 1 movably. A blocking block 453 is installed at the end of the push rod 45. A sleeve 454 communicated with the heat exchange chamber is arranged on the side wall of the heat exchange cover 1. The push rod 45 passes through the sleeve 454 movably. The diameter of the push rod 45 is smaller than that of the sleeve 454, and the diameter of the blocking block 453 is larger than that of the sleeve 454. A connecting cover 251 is installed on the side wall of the heat exchange cover 1, and the connecting cover 251 covers the outside of the sleeve 454. A liquid outlet pipe 25 is connected to the top of the connecting cover 251. When the push plate 44 rotates, the push plate 44 can push the push rod 45 installed with the sliding rod 452 to slide along the limit seat 451 at this time. The blocking block 453 at the end of the push rod 45 is separated from the sleeve 454, controlling the opening and closing of the outlet of the heat exchange cavity.

[0027] The implementation principle of an intelligent chemical heat exchanger with a drainage structure of the present invention is as follows: When this chemical heat exchanger is in normal use, a heat exchange medium is input into it along the input pipe 122. Then the heat exchange medium can flow along the heat exchange interlayer 12 in the heat exchange cover 1. Finally, the medium can be transported out along the output end 123. Among them, the liquid that needs to be heat-exchanged at this time can be placed in the first heat exchange chamber 111 and the second heat exchange chamber 112, thus completing the heat exchange operation.

[0028] Taking Figure 3At this time, the state of the first heat exchange chamber 111 at the top is as follows: the notch 243 of the liquid inlet pipe 2 connected to the first heat exchange chamber 111 is open, and the discharge port of the first heat exchange chamber 111, the plugging block 453 and the sleeve 454 are separated. Therefore, the entire first heat exchange chamber 111 is in a flowing state at this time, so heat exchange operations can be performed on the flowing heat exchange liquid. During the heat exchange process, the deposits that may be generated are simultaneously transported outwards by the flowing liquid, reducing the possibility of accumulation in the heat exchange chamber.

[0029] At this time, the state of the second heat exchange chamber is as follows: the notch 243 of the liquid inlet pipe 2 connected to the second heat exchange chamber 112 is closed, and the discharge port of the second heat exchange chamber 112 is simultaneously sealed. Therefore, the second heat exchange chamber 112 is sealed at this time, so better heat exchange operations can be performed on the heat exchange liquid.

[0030] In the above specific operation, the states of the first heat exchange chamber 111 and the second heat exchange chamber 112 will change. During the transportation of the heat exchange liquid, the heat exchange liquid can flow in the liquid inlet pipe 2, impact the turbulence fan blades 23, and then drive the turbulence fan blades 23 to start rotating. While the turbulence fan blades 23 are rotating, the synchronous shaft 232 at the center of rotation rotates on the cross support 233, and the synchronous shaft 232 drives the bottom drive shaft 24 to rotate. At this time, the bottom drive shaft 24 can drive the two sealing blocks 241 to rotate. During the rotation process, the sealing block 241 connected to the first heat exchange chamber 111 can plug the notch 243 of the first heat exchange chamber 111, and at this time, the inner groove 242 of the other sealing block 241 can correspond to the notch 243 of the second heat exchange chamber 112, opening the notch.

[0031] Therefore, at this time, the liquid inlet states of the first heat exchange chamber 111 and the second heat exchange chamber 112 change alternately.

[0032] Then, at this time, the liquid can enter the second heat exchange chamber 112 through the liquid inlet pipe 2. The liquid can flow at a high speed in the second heat exchange chamber 112, and then push the push plate 44 inside the second heat exchange chamber 112 to rotate counterclockwise. When the push plate 44 rotates, the push plate 44 can push the push rod 45 installed with the slide rod 452 to slide along the limit seat 451. The plugging block 453 at the end of the push rod 45 and the sleeve 454 are separated, and then the state of the liquid flow inside the second heat exchange chamber 112 changes.

[0033] And when the push plate 44 rotates, the push plate 44 drives the hollow shaft 41 to rotate. At this time, the hollow shaft 41 drives the drainage plate 4 to rotate. At this time, the drainage plate 4 rotates from the first heat exchange chamber 111 to the second heat exchange chamber 112. Then, the fluid that has just entered the second heat exchange chamber 112 is dispersed into multiple thin streams, enabling the fluid to uniformly contact the inner wall of the heat exchange chamber, greatly improving the heat exchange efficiency. And since the drainage plate 4 is hollow, during the drainage process, the liquid can also conduct heat exchange on the surface of the drainage plate 4, increasing the heat exchange area and making the heat exchange efficiency higher.

[0034] When the hollow shaft 41 rotates, the push plate 44 located in the first heat exchange chamber 111 rotates synchronously, pulling the push rod 45 of the first heat exchange chamber 111 to move leftward at this time, thereby sealing the sleeve 454 at this position, and then ensuring that the inside of the first heat exchange chamber 111 is in a sealed state and the liquid is in a static state synchronously.

[0035] However, for the first heat exchange chamber 111, the drainage plate 4 originally located inside the first heat exchange chamber 111 has now rotated into the second heat exchange chamber 112. As a result, the space of the first heat exchange chamber 111 has become larger. Therefore, the liquid in the first heat exchange chamber 111 may not completely fill the entire chamber at this time, which may lead to low heat exchange efficiency. However, during this process, the inner groove 242 located in the first heat exchange chamber 111 is in contact with the ejector rod 31, so the ejector rod 31 moves rightward. The ejector rod 31 can drive the compression plate 3 to move rightward, thereby compressing the space of the first heat exchange chamber 111, enabling the water body to fill the entire first heat exchange chamber 111, and then making the heat exchange more sufficient. Among them, the energy storage spring 323 in the energy storage cover 32 drives the energy storage rod 324 to always have a tendency to move rightward, and the ejector rod 31 is always in contact with the side wall of the sealing block 241.

[0036] As the turbulence fan blades 23 continuously rotate, the first heat exchange chamber 111 and the second heat exchange chamber 112 can rotate alternately.

[0037] During heat exchange of the present invention, the design of alternately feeding liquid into the double heat exchange chambers and the dynamic adjustment of the diversion plate 4 greatly improve the heat exchange efficiency. When the fluid enters the second heat exchange chamber 112, the diversion plate 4 disperses it into multiple thin streams, which not only allows the fluid to uniformly contact the inner wall of the chamber, but also the hollow diversion plate 4 increases the heat exchange area and strengthens the heat exchange. At the same time, the compression component adjusts the space of the first heat exchange chamber 111 to ensure that the chamber is filled with liquid and avoid the reduction of heat exchange efficiency due to wasted space. During the whole process, the chamber in the flowing state transports the sediments outwards synchronously by means of the liquid flow, realizing automatic silt cleaning and blockage prevention, reducing the decline of heat exchange efficiency caused by dirt accumulation and the risk of equipment failure, while the chamber in the static state can fully exchange heat with the heat of the input liquid, reducing heat loss. In addition, the present invention senses the fluid flow through the turbulence fan blade 23 and automatically drives the sealing block 241, the push plate 44 and the compression component to move in cooperation, realizing the dynamic adjustment of the liquid inlet state, the space size of the heat exchange chamber and the position of the diversion plate. This design not only enables the heat exchanger to maintain its own cleanliness while efficiently exchanging heat, but also can automatically adjust the operating parameters according to different fluid flow rates, temperatures and properties to adapt to the complex and changeable chemical production working conditions.
