Chemical heat exchanger with energy-saving improved structural design

Abstract

This invention discloses a chemical heat exchanger with an energy-saving improved structural design, including a heat exchange tank. A connecting plate is fixedly installed at the end of the heat exchange tank, and a tank cover is provided on the side of the connecting plate away from the heat exchange tank. A processing component is provided inside the tank cover. When heat exchange is performed, hot and cold liquids flow inside the heat exchange tank, and the scale generated by the liquids adheres to the inside of the heat exchange tank and needs to be cleaned. At this time, a waterproof motor is started, and a rotating rod fixedly installed at its output end begins to rotate. A limiting ring fixedly installed at the end of the rotating rod drives a reciprocating screw to rotate accordingly. Because the scraper ring is slidably set against the outer wall of the heat exchange tube, under its restriction, the rotating reciprocating screw drives the sleeve plate fitted on its outer wall to move back and forth, so that the sleeve plate drives the scraper ring to slide against the outer wall of the heat exchange tube through the extrusion rod. Because the scraper ring slides in close contact with the outer wall of the heat exchange tube, the scale attached to the outer wall of the heat exchange tube can be cleaned.

Description

Technical Field

[0001] This invention relates to the field of chemical heat exchangers, specifically a chemical heat exchanger with an energy-saving improved structural design. Background Technology

[0002] Chemical heat exchangers are crucial equipment in chemical production processes. Their main function is to achieve heat exchange between different media. In chemical reactions and material handling, heat exchangers can be used to heat, cool, evaporate, or condense materials, thereby ensuring the normal operation of the process and the stability of product quality. Energy-saving and structurally improved chemical heat exchangers refer to equipment that improves heat exchange efficiency and reduces energy consumption by optimizing the design based on traditional heat exchangers.

[0003] For example, a chemical heat exchanger with an energy-saving improved structural design disclosed in Chinese patent CN213363495U has baffles installed on a baffle fixing frame, which is inserted into the shell. When the baffles need to be cleaned or replaced, the baffle fixing frame can be pulled out of the shell for cleaning or replacement without removing the baffles from the shell, saving time and costs. The baffle fixing frame is positioned using a fixing frame positioning block, which is simple in structure and easy to operate. The outer end of the baffle fixing frame is provided with a fixing frame guide strip, which makes the positioning more accurate when the baffle fixing frame is inserted into the shell.

[0004] While the baffles can be disassembled to clean scale in this structure, this operation will gradually reduce the heat exchange effect until a large amount of scale adheres before disassembly. Therefore, we propose a chemical heat exchanger with an energy-saving improved structural design that can clean scale in the heat exchanger in a timely manner and ensure a uniform heat exchange effect. Summary of the Invention

[0005] The purpose of this invention is to provide a chemical heat exchanger with an energy-saving improved structural design to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a chemical heat exchanger with an energy-saving improved structural design, including a heat exchange tank, a connecting plate fixedly installed at the end of the heat exchange tank, a tank cover provided on the side of the connecting plate away from the heat exchange tank, and a processing component provided inside the tank cover. The processing component includes a cleaning component provided inside the heat exchange tank, a heat exchange component provided inside the cleaning component, and a vibration damping component provided below the heat exchange component.

[0007] According to the above technical solution, the cleaning component includes a support plate fixedly installed on the inner wall of the connecting plate, an installation plate fixedly installed on the outer wall of the support plate, a waterproof motor fixedly installed on the outer wall of the installation plate, a rotating rod fixedly installed on the output end of the waterproof motor, a limit ring fixedly installed on the end of the rotating rod away from the waterproof motor, a reciprocating screw fixedly installed on the side of the limit ring away from the rotating rod, a sleeve plate sleeved on the outer wall of the reciprocating screw, a pressing rod fixedly installed on the side wall of the sleeve plate, a scraper ring fixedly installed on the outer wall of the sleeve plate, a connecting plate fixedly installed on the outer wall of the scraper ring, a scraper ring fixedly installed on the end of the connecting plate away from the scraper ring, a fixing plate fixedly installed on the inner wall of the heat exchange tank, a limit rod fixedly installed on the side wall of the fixing plate, a first magnetic ring fixedly installed on the outer wall of the limit rod, a sleeve block slidably arranged on the outer wall of the limit rod, a second magnetic ring fixedly installed on the side wall of the sleeve block, and a baffle plate fixedly installed on the outer wall of the sleeve block.

[0008] According to the above technical solution, the heat exchange assembly includes a hot fluid inlet connected to the tank cover, a hot fluid outlet connected to the outer wall of the heat exchange tank, a cold fluid inlet at the end of the heat exchange tank away from the hot fluid inlet, a water collection tray connected to the end of the cold fluid inlet, a heat exchange tube connected to the outer wall of the water collection tray, a water collection ring connected to the end of the heat exchange tube away from the water collection tray, and a cold fluid outlet connected to the outer wall of the water collection ring.

[0009] According to the above technical solution, the shock absorption component includes a fixed ring fixedly installed on the outer wall of the heat exchange tank, a bracket fixedly installed on the outer wall of the fixed ring, a sliding plate fixedly installed at the bottom of the bracket, a sliding rod slidably arranged inside the sliding plate, a spring sleeved on the outer wall of the sliding rod, a base plate fixedly installed at the end of the sliding rod, and a damper fixedly installed on the top surface of the base plate.

[0010] According to the above technical solution, the scraper ring is slidably disposed with the outer wall of the heat exchange tube, and the sleeve plate is movably sleeved with the reciprocating screw. Under the sliding restriction of the scraper ring and the heat exchange tube, the rotating reciprocating screw can drive the sleeve plate to reciprocate.

[0011] According to the above technical solution, the baffle plate is slidably arranged inside the heat exchange tank. The first magnetic ring and the second magnetic ring are magnetically repulsive. When the baffle plate is not squeezed, under the restriction of magnetic repulsion, the baffle plate is reset and pushed, so that the baffle plate vibrates and cleans the scale attached to its outer wall.

[0012] According to the above technical solution, there are eight heat exchange tubes distributed around the center of the water collection tray. The heat exchange tubes are arranged in a U-shape, which can increase the heat exchange area and improve the heat exchange effect.

[0013] According to the above technical solution, one end of the spring is fixedly installed to the bottom of the slide plate, and the end of the spring away from the slide plate is fixedly installed to the top surface of the base plate. Under the constraint of the spring, the swaying heat exchange tank can be buffered and the force can be released. With the help of the damper, the shock absorption and buffering effect can be achieved.

[0014] Compared with the prior art, the beneficial effects achieved by the present invention are:

[0015] 1. This invention relates to a chemical heat exchanger with an energy-saving and improved structural design. One component is a cleaning assembly. During heat exchange, hot and cold liquids flow inside the heat exchange tank, and scale generated by the liquids adheres to the inside of the tank, requiring cleaning. At this time, a waterproof motor is started, and a rotating rod fixedly installed at its output end begins to rotate. A limiting ring fixedly installed at the end of the rotating rod drives a reciprocating screw to rotate accordingly. Due to the sliding arrangement of the scraper ring against the outer wall of the heat exchange tube, under its constraint, the rotating reciprocating screw drives the sleeve plate fitted on its outer wall to move back and forth, causing the sleeve plate to drive the scraper ring through the pressing rod. The scraper ring slides along the outer wall of the heat exchange tube, effectively cleaning the scale adhering to the outer wall. As the scraper ring reciprocates inside the heat exchange tank, the connecting plate fixed to its outer wall moves the scraper ring accordingly, causing it to slide against the inner wall of the heat exchange tank, cleaning the scale on the inner wall and preventing scale from adhering to the inner wall for extended periods, thus extending the service life of the heat exchange tank. This structure allows for timely cleaning of scale adhering to the outer wall of the heat exchange tube, resulting in better heat exchange performance, and the cleaning of the inner wall of the heat exchange tank extends its service life.

[0016] 2. The present invention relates to a chemical heat exchanger with an energy-saving improved structural design. One component is a cleaning assembly. When the sleeve plate reciprocates inside the heat exchange tank, the pressing rod fixedly installed on its side wall moves accordingly. The outer wall of the pressing rod contacts and presses against the baffle plate, causing the sleeve block fixedly installed on the outer wall of the baffle plate to slide on the outer wall of the limiting rod. This pushes the baffle plate and the second magnetic ring fixedly installed on its outer wall towards the first magnetic ring. When the pressing rod collides with the baffle plate, the baffle plate vibrates, shaking off the scale adhering to its outer wall. When the pressing rod moves away from the baffle plate, the baffle plate is no longer compressed. Under the magnetic repulsion between the second and first magnetic rings, it pushes the baffle plate towards the pressing rod, causing the baffle plate to slide and shaking off the scale adhering to its outer wall. This structure causes the baffle plate to reciprocate, generating a vibration effect to shake off the scale adhering to its outer wall, thereby improving the overall heat exchange efficiency.

[0017] 3. The present invention provides a chemical heat exchanger with an energy-saving and improved structural design. One component consists of heat exchange elements. When heat exchange is required, hot liquid is transported into the heat exchange tank through a hot fluid inlet, while cold liquid is transported into a water collection pan through a cold fluid inlet. From the water collection pan, the liquid is transported into the heat exchange tubes. The hot liquid passes through the heat exchange tubes and is cooled by the cold liquid inside, thus performing heat exchange. The hot liquid after heat exchange is discharged through a hot fluid outlet, while the cold liquid is transported into a water collection ring and then discharged through the cold fluid outlet. Because the heat exchange tubes are U-shaped, the heat exchange area is increased, thereby improving the heat exchange effect.

[0018] 4. The chemical heat exchanger of this invention features an energy-saving and improved structural design. One component is a shock-absorbing assembly. When the heat exchanger is working, the liquid flowing and colliding inside the heat exchange tank causes it to shake, requiring buffering. When the heat exchange tank shakes, the fixing ring causes the sliding plate fixedly installed at the bottom of the support to slide against the outer wall of the sliding rod fixedly installed on the top surface of the base plate. The sliding plate compresses the spring fitted onto the outer wall of the sliding rod. Under the elastic action of the spring, the shaking force is buffered. During spring buffering, elastic potential energy is generated, which is then offset by a damper to reduce overall shock absorption and extend the service life of the heat exchanger.

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0034] Example 1: A preferred embodiment of the chemical heat exchanger with an energy-saving improved structural design provided by the present invention is as follows: Figures 1 to 9 As shown: A chemical heat exchanger with an energy-saving improved structural design includes a heat exchange tank 1;

[0035] A connecting plate 2 is fixedly installed at one end of the heat exchange tank body 1;

[0036] A tank cover 3 is provided on the side of the connecting plate 2 away from the heat exchange tank 1;

[0037] And a processing component 4 disposed inside the tank cover 3. The processing component 4 includes a cleaning component 41 disposed inside the heat exchange tank 1. The cleaning component 41 includes a support plate 427 fixedly installed on the inner wall of the connecting plate 2. An installation plate 411 is fixedly installed on the outer wall of the support plate 427. A waterproof motor 412 is fixedly installed on the outer wall of the installation plate 411. A rotating rod 413 is fixedly installed at the output end of the waterproof motor 412. A limit ring 414 is fixedly installed at the end of the rotating rod 413 away from the waterproof motor 412. A reciprocating screw 415 is fixedly installed on the side of the limit ring 414 away from the rotating rod 413. A sleeve plate is fitted on the outer wall of the reciprocating screw 415. 416, a squeezing rod 417 is fixedly installed on the side wall of the sleeve plate 416, a scraper ring 418 is fixedly installed on the outer wall of the sleeve plate 416, a connecting plate 419 is fixedly installed on the outer wall of the scraper ring 418, a scraper ring 420 is fixedly installed on the end of the connecting plate 419 away from the scraper ring 418, a fixing plate 421 is fixedly installed on the inner wall of the heat exchange tank 1, a limit rod 422 is fixedly installed on the side wall of the fixing plate 421, a first magnetic ring 423 is fixedly installed on the outer wall of the limit rod 422, a sleeve block 424 is slidably arranged on the outer wall of the limit rod 422, a second magnetic ring 425 is fixedly installed on the side wall of the sleeve block 424, and a baffle plate 426 is fixedly installed on the outer wall of the sleeve block 424.

[0038] In this embodiment, during heat exchange, hot and cold liquids flow inside the heat exchange tank 1. Scale generated by the liquids adheres to the inside of the heat exchange tank 1 and needs to be cleaned. At this time, the waterproof motor 412 is started, and the rotating rod 413 fixedly installed at its output end begins to rotate. The limiting ring 414 fixedly installed at the end of the rotating rod 413 drives the reciprocating screw 415 to rotate accordingly. Because the scraper ring 418 slides against the outer wall of the heat exchange tube 435, under its constraint, the rotating reciprocating screw 415 drives the sleeve plate 416 fitted on its outer wall to move back and forth, causing the sleeve plate 416 to pass through the extrusion rod. 417 drives the scraper ring 418 to slide on the outer wall of the heat exchange tube 435. Because the scraper ring 418 slides in close contact with the outer wall of the heat exchange tube 435, the scale adhering to the outer wall of the heat exchange tube 435 can be cleaned. When the scraper ring 418 reciprocates inside the heat exchange tank 1, the connecting plate 419 fixedly installed on its outer wall drives the scraper ring 420 to move accordingly, causing the scraper ring 420 to contact and slide against the inner wall of the heat exchange tank 1, cleaning the scale on the inner wall of the heat exchange tank 1. This prevents scale from adhering to the inner wall of the heat exchange tank 1 for a long time, affecting the service life of the heat exchange tank 1. This structure can effectively clean the outer wall of the heat exchange tube 435. Timely cleaning of adhering scale improves the heat exchange efficiency of heat exchange tube 435 and extends the service life of heat exchange tank 1 by cleaning the inner wall of heat exchange tank 1. When sleeve plate 416 reciprocates inside heat exchange tank 1, the extrusion rod 417 fixedly installed on its side wall moves accordingly. The outer wall of extrusion rod 417 contacts and extrudes baffle plate 426, causing sleeve block 424 fixedly installed on the outer wall of baffle plate 426 to slide on the outer wall of limit rod 422, pushing baffle plate 426 and its second magnetic ring 425 fixedly installed on its outer wall towards the first magnetic ring 423. When extrusion rod 417 contacts baffle plate 426, the extrusion rod 417 reciprocates and extrudes the baffle plate 426. When the baffle plate 426 collides, it vibrates, shaking off the scale adhering to its outer wall. When the extrusion rod 417 moves away from the baffle plate 426, the baffle plate 426 is no longer compressed. Under the magnetic repulsion between the second magnetic ring 425 and the first magnetic ring 423, it pushes the baffle plate 426 towards the extrusion rod 417, causing the baffle plate 426 to slide and shaking off the scale adhering to its outer wall. This structure causes the baffle plate 426 to move back and forth to generate a vibration effect, shaking off the scale adhering to its outer wall and improving the overall heat exchange effect.

[0039] Example 2: A preferred embodiment of the chemical heat exchanger with an energy-saving improved structural design provided by the present invention is as follows: Figures 1 to 9 As shown: The heat exchange assembly 43 includes a hot fluid inlet 431 connected to the tank cover 3, a hot fluid outlet 432 connected to the outer wall of the heat exchange tank 1, a cold fluid inlet 433 at the end of the heat exchange tank 1 away from the hot fluid inlet 431, a water collection tray 434 connected to the end of the cold fluid inlet 433, a heat exchange tube 435 connected to the outer wall of the water collection tray 434, a water collection ring 436 connected to the end of the heat exchange tube 435 away from the water collection tray 434, and a cold fluid outlet 437 connected to the outer wall of the water collection ring 436.

[0040] In this embodiment, when heat exchange is required, hot liquid is transported into the heat exchange tank 1 through hot fluid inlet 431, and cold liquid is transported into the water collection pan 434 through cold fluid inlet 433. The water collection pan 434 then transports the hot liquid into the heat exchange tube 435. The hot liquid passes through the heat exchange tube 435 and is cooled by the cold liquid inside the heat exchange tube 435 to perform heat exchange. The hot liquid after heat exchange is discharged through hot fluid outlet 432, and the cold liquid is transported into the water collection ring 436 and then discharged through the cold fluid outlet 437 to perform heat exchange. Since the heat exchange tube 435 is U-shaped, the heat exchange area is increased to improve the heat exchange effect.

[0041] Example 3: A preferred embodiment of the chemical heat exchanger with an energy-saving improved structural design provided by the present invention is as follows: Figures 1 to 9 As shown: The shock absorption assembly 44 includes a fixing ring 441 fixedly installed on the outer wall of the heat exchange tank 1. A bracket 442 is fixedly installed on the outer wall of the fixing ring 441. A sliding plate 443 is fixedly installed at the bottom of the bracket 442. A sliding rod 444 is slidably arranged inside the sliding plate 443. A spring 445 is sleeved on the outer wall of the sliding rod 444. A base plate 447 is fixedly installed at the end of the sliding rod 444. A damper 446 is fixedly installed on the top surface of the base plate 447.

[0042] In this embodiment, when the heat exchanger is working, the liquid flows and collides inside the heat exchange tank 1, causing the heat exchange tank 1 to shake. It needs to be buffered. When the heat exchange tank 1 shakes, the fixing ring 441 causes the sliding plate 443 fixedly installed at the bottom of the bracket 442 to slide on the outer wall of the sliding rod 444 fixedly installed on the top surface of the base plate 447. The sliding plate 443 compresses the spring 445 sleeved on the outer wall of the sliding rod 444. Under the elastic action of the spring 445, the shaking force is buffered. When the spring 445 buffers, it generates elastic potential energy, which is then offset by the damper 446 to reduce the vibration of the heat exchanger as a whole and extend the service life of the heat exchanger.

[0043] The scraper ring 418 is slidably disposed on the outer wall of the heat exchange tube 435, and the sleeve plate 416 is movably sleeved on the reciprocating screw 415. Under the sliding restriction of the scraper ring 418 and the heat exchange tube 435, the rotating reciprocating screw 415 can drive the sleeve plate 416 to reciprocate.

[0044] The baffle plate 426 is slidably disposed inside the heat exchange tank 1. The first magnetic ring 423 and the second magnetic ring 425 are magnetically repulsive. When the baffle plate 426 is not squeezed, under the restriction of magnetic repulsion, the baffle plate 426 is reset and pushed, so that the baffle plate 426 vibrates and cleans the scale attached to its outer wall.

[0045] There are eight heat exchange tubes 435, which are distributed around the center of the water collection plate 434. The heat exchange tubes 435 are arranged in a U-shape, which can increase the heat exchange area and improve the heat exchange effect.

[0046] One end of the spring 445 is fixedly installed at the bottom of the slide plate 443, and the other end of the spring 445 away from the slide plate 443 is fixedly installed at the top surface of the base plate 447. Under the restriction of the spring 445, the swaying heat exchange tank 1 can be buffered and the force can be released. With the help of the damper 446, the shock absorption and buffering effect can be achieved.
