Description

Technical Field

[0001] The invention relates to the field of heat exchangers, in particular to a heat exchanger for chemical industry which is easy to disassemble and clean. Background Art

[0002] Chemical heat exchangers are very critical equipment in the chemical production process. Their main function is to achieve heat exchange between different media. In chemical reactions and material handling processes, heat exchangers can be used to heat, cool, evaporate or condense materials, thereby ensuring the normal progress of the process and the stability of product quality. In the chemical industry, heat exchangers are key heat exchange equipment. They are used for heating, cooling, evaporation and condensation in a variety of process operations. In order to ensure high efficiency and long-term stable operation, heat exchangers need to be disassembled and cleaned regularly to remove accumulated dirt and sediment. Heat exchanger designs that are easy to disassemble and clean are particularly important for chemical applications because they can reduce maintenance costs, reduce downtime, and maintain heat exchange efficiency.

[0003] For example, Chinese patent CN116697775B discloses a heat exchanger for chemical industry that is easy to disassemble and clean. The protective shell of the heat exchanger can be supported and limited by the support frame. When the heat exchanger needs to be cleaned, the personnel will remove the bolts connecting the heat exchange mechanism, the protective shell and the removable end cover, start the second adjustment mechanism to drive the removable end cover to move through the second support moving mechanism, and start the first adjustment mechanism to drive the heat exchange mechanism to move out of the protective shell through the first support moving mechanism, so that it is convenient for personnel to separate and clean the removable end cover, the heat exchange mechanism and the protective shell. At the same time, it can also keep the position of the removable end cover, the heat exchange mechanism and the protective shell as much as possible, which is convenient for personnel to install the removable end cover, the heat exchange mechanism and the protective shell in situ later, making the present application more convenient during disassembly and cleaning, and at the same time can The disassembly and cleaning efficiency is improved to a certain extent. The water inlet pipe and the water outlet pipe are arranged to cooperate with each other to control the flow of liquid inside the shell. The second connecting flange plate can limit the connection position between the tube box, the tube sheet and the first connecting flange plate by cooperating with the bolts. The heat exchange liquid inlet can transport the heat exchange liquid into the tube box above the partition plate. The heat exchange liquid enters the heat exchange tube through the tube sheet for heat exchange, and then is transported into the tube box below the partition plate and discharged outward through the heat exchange liquid outlet. The forward and reverse motors arranged are started to drive the threaded rod to rotate, which can drive the first movable plate to move. When the first movable plate moves, the tube sheet can be driven to move by cooperating with the first triangular support plate and the first arc-shaped connecting plate. When the second adjusting mechanism is started, the second movable plate can drive the tube box to move by cooperating with the second triangular support plate and the second arc-shaped connecting plate.

[0004] For this structure, although the heat exchanger can be disassembled and cleaned, the heat exchanger needs to remove the bolts, which will rust after long-term use, making it inconvenient to disassemble the heat exchanger. Therefore, we propose a chemical heat exchanger that can quickly disassemble and assemble the heat exchanger, making it more convenient to clean and easy to disassemble and clean. Summary of the invention

[0008] According to the above technical solution, the lifting assembly includes a second bracket fixedly installed on the top surface of the base, a second motor is fixedly installed on the outer wall of the second bracket, a second opposing threaded rod is fixedly installed on the output end of the second motor, a sleeve block is sleeved on the outer wall of the second opposing threaded rod, a connecting frame is fixedly installed on the outer wall of the sleeve block, a limiting strip is slidingly arranged at the bottom of the sleeve block, the outer wall of the sleeve block is hingedly connected to a connecting plate, and the connecting plate is hingedly connected to a fixing ring at one end away from the sleeve block.

[0009] According to the above technical solution, the clamping assembly includes a heat exchange tube that is slidably arranged inside the baffle and is connected to each other. A baffle is fixedly installed on the outer wall of the heat exchange tube. A slide groove is provided on the outer wall of the baffle. A first magnetic plate is fixedly installed on the inner wall of the slide groove. A second magnetic plate is slidably arranged inside the slide groove. A clamping column is fixedly installed on the side wall of the second magnetic plate. A clamping groove is provided on the inner wall of the heat exchange tank.

[0010] According to the above technical solution, the ring gasket is sleeved inside the ring groove, and the ring gasket is made of rubber. Under its limitation, the sealing of the connection between the heat exchange tank and the end cover can be increased to avoid leakage of the heat exchange liquid.

[0011] According to the above technical solution, the outer wall of the first sealing ring is slidably arranged inside the bent pipe, and the outer wall of the second sealing ring is slidably arranged inside the bent pipe. Since the first sealing ring and the second sealing ring are sealed and slidably arranged inside the bent pipe, under their restriction, when the first sealing ring slides toward the inside of the bent pipe, it can push the gas inside the bent pipe to make the second sealing ring slide toward the outside of the bent pipe, so as to push the push rod fixedly installed on the side wall of the second sealing ring, so that the push rod pushes the protective ring.

[0012] According to the above technical solution, the fixing ring is fixedly installed on the outer wall of the heat exchange tank, and the sleeve block is slidably arranged on the outer wall of the limiting strip. Under the restriction of the limiting strip, the rotating second opposing threaded rod drives the sleeve block to move.

[0013] According to the above technical solution, the first magnetic plate and the second magnetic plate magnetically repel each other, and the end of the clamping column is arranged in a spherical surface, under which the clamping column is stably clamped with the inside of the clamping slot.

[0014] Compared with the prior art, the beneficial effects achieved by the present invention are: 1. The chemical heat exchanger of the present invention is easy to disassemble and clean, and one of its components is composed of a disassembly assembly component. When the inside of the heat exchange tank needs to be cleaned, the first motor is started, and the first opposing threaded rods fixedly installed at the output end of the motor start to rotate. Since the sleeve ring fixedly installed at the end of the sleeve plate and the outer wall of the limit rod are slidingly arranged, under their restriction, the rotating first opposing threaded rods drive the two sleeve plates to move in the opposite direction, and the sleeve plate drives the sleeve ring and the fixed plate fixedly installed on the outer wall of the sleeve ring to move, so that the fixed plate drives the end cover to move, so that the annular groove provided on the outer wall of the end cover is no longer clamped with the ring gasket fixedly installed at the end of the heat exchange tank. At this time, the end cover and the inside of the heat exchange tank can be cleaned. This structure can quickly disassemble the end cover and the heat exchange tank, making cleaning more convenient. Under the restriction of the clamping connection between the ring gasket and the annular groove, the end cover and the heat exchange tank are more sealed.

[0015] 2. The chemical heat exchanger of the present invention is easy to disassemble and clean, and one of its components is composed of a disassembly assembly component. When the heat exchange tank and the end cover are cleaned, the first motor is started to drive the first opposing threaded rod to rotate, so that the two sleeves move in opposite directions. The sleeve ring fixedly installed at the end of the sleeve plate slides on the outer wall of the limit rod, so that the sleeve ring drives the fixed plate and the end cover fixedly installed at the end of the fixed plate to move toward the heat exchange tank. The side wall of the end cover contacts and squeezes the pressure rod, so that the first sealing ring fixedly installed at the end of the pressure rod slides toward the inside of the elbow. Under the support of the retaining ring, the spring is compressed. Since the first sealing ring slides with the inner wall of the elbow in a sealed manner, under its restriction, the first sealing ring pushes the gas inside the elbow to make the second sealing ring sliding inside the elbow and the push rod move toward The push rod pushes the protective ring to make the protective ring and the rubber ring fixedly installed on its inner wall slide toward the outside of the end cover, and the protective ring and the rubber ring seal the connection between the end cover and the heat exchange tank to prevent leakage of the heat exchange liquid. When the end cover moves away from the heat exchange tank, the end cover no longer squeezes the pressure rod. Under the elastic action of the spring, it resets and pushes the pressure rod. The first sealing ring fixedly installed on the end of the pressure rod slides toward the outside of the elbow, and the first sealing ring pumps the gas inside the elbow to make the second sealing ring fixedly installed on the end of the push rod slide toward the inside of the elbow. The push rod pulls the protective ring, so that the protective ring and the rubber ring fixedly installed on its inner wall are no longer mounted on the connection between the heat exchange tank and the end cover, so the inside of the heat exchange tank and the end cover can be cleaned.

[0016] 3. The chemical heat exchanger of the present invention is easy to disassemble and clean, and one of its components is composed of a lifting assembly. When the end cover moves away from the heat exchange tank, the second motor is started, and the second opposing threaded rods fixedly installed at the output end thereof rotate accordingly. Since the sleeve block fixedly installed at the end of the connecting frame is sleeved with the second opposing threaded rods, and the sleeve block and the outer wall of the limit bar are slidably arranged, under the restriction of the sleeve block, the rotating second opposing threaded rods can drive the two groups of sleeve blocks to move in the opposite direction. Since the end of the connecting plate is hingedly connected to the sleeve block and the fixed ring, under the restriction of the sleeve block, the sleeve block pushes the fixed ring through the connecting plate, so that the heat exchange tank fixedly installed inside the fixed ring moves upward, and the heat exchange tank is pushed upward. At this time, the heat exchange tubes and baffles arranged inside the heat exchange tank can be disassembled. This structure can make the cleaning of the heat exchange tank more convenient.

[0017] 4. The chemical heat exchanger of the present invention is easy to disassemble and clean, and one of its components is composed of a snap-on assembly. When the heat exchanger needs to be cleaned, the heat exchange tank and the end cover are opened to clean the inside. At this time, the heat exchange tank is lifted up, and the baffle is pulled. The end of the card column slidingly arranged inside the slide groove opened on the outer wall of the baffle is squeezed with the slot opened on the inner wall of the heat exchange tank. Since the end of the card column is spherical, the card column and the slot can be smoothly squeezed under its restriction, so that the baffle, heat exchange tube and baffle can be disassembled. After cleaning, the card column is aligned and snapped with the slot. When the card column is not squeezed, under the restriction of the magnetic repulsion between the second magnetic plate and the first magnetic plate, the card column is slid toward the outside of the slide groove, so that the card column and the slot are snapped, so as to prevent the baffle from sliding inside the base when the heat exchange tank is raised or lowered.

[0021] In this embodiment, when it is necessary to clean the inside of the heat exchange tank 2, the first motor 412 is started, and the first opposing threaded rods 413 fixedly installed at the output end thereof begin to rotate. Since the collar 415 fixedly installed at the end of the collar plate 414 is slidably arranged with the outer wall of the limiting rod 416, under its restriction, the rotating first opposing threaded rods 413 drive the two collar plates 414 to move in the opposite direction, and the collar plate 414 drives the collar 415 and the fixing plate 417 fixedly installed on the outer wall of the collar 415 to move, so that the fixing plate 417 drives the end cover 3 to move, so that the annular groove 418 provided on the outer wall of the end cover 3 is no longer engaged with the annular gasket 419 fixedly installed at the end of the heat exchange tank 2.

Under the clamping restriction of the ring gasket 419 and the ring groove 418, the end cover 3 and the heat exchange tank 2 are more sealed. When the heat exchange tank 2 and the end cover 3 are cleaned, the first motor 412 is started, which drives the first opposing threaded rod 413 to rotate, so that the two sleeve plates 414 move in opposite directions, and the sleeve ring 415 fixedly installed at the end of the sleeve plate 414 slides on the outer wall of the limit rod 416, so that the sleeve ring 415 drives the fixed plate 417 and the end cover 3 fixedly installed at the end of the fixed plate 417 to move toward the heat exchange tank 2, and the side wall of the end cover 3 contacts and squeezes the pressure rod 425, so that the pressure rod 42 The first sealing ring 424 fixedly installed at the end slides toward the inside of the elbow 421, and under the support of the retaining ring 422, the spring 423 is compressed.

[0023] In this embodiment, when the end cover 3 moves away from the heat exchange tank 2, the second motor 432 is started, and the second opposing threaded rod 433 fixedly installed at its output end rotates accordingly. Since the sleeve block 434 fixedly installed at the end of the connecting frame 435 is sleeved with the second opposing threaded rod 433, and the sleeve block 434 and the outer wall of the limit bar 437 are slidably arranged, under its restriction, the rotating second opposing threaded rod 433 can drive the two groups of sleeve blocks 434 to move in the opposite direction.

After cleaning, the card column 447 is aligned and clamped with the card groove 448. When the card column 447 is not squeezed, under the restriction of the magnetic repulsion between the second magnetic plate 446 and the first magnetic plate 445, the card column 447 is slid toward the outside of the slide groove 444, so that the card column 447 and the card groove 448 are clamped, so as to prevent the baffle 441 from sliding inside the base 1 when the heat exchange tank 2 is raised or lowered.

Since the first sealing ring 424 and the second sealing ring 426 are sealed and slidably arranged inside the curved pipe 421, under their restriction, when the first sealing ring 424 slides toward the inside of the curved pipe 421, it can push the internal gas of the curved pipe 421 to make the second sealing ring 426 slide toward the outside of the curved pipe 421, so as to push the push rod 427 fixedly installed on the side wall of the second sealing ring 426, so that the push rod 427 pushes the protective ring 428.

[0028] The fixing ring 438 is fixedly installed on the outer wall of the heat exchange tank 2, and the sleeve block 434 is slidably arranged on the outer wall of the limiting strip 437. Under the restriction thereof, the rotating second opposing threaded rod 433 drives the sleeve block 434 to move.
