Description
Technical Field
[0001] This invention relates to the field of plate heat exchanger technology, and particularly to a corrosion-resistant symmetrical flow channel plate heat exchanger. Background Technology
[0002] During use, existing plate heat exchangers are prone to scale formation on the flow channel surface, such as calcium carbonate, calcium sulfate, and sludge. This leads to a decrease in heat transfer coefficient and an increase in resistance. Traditional stainless steel heat exchange plates also experience localized corrosion and rust formation during long-term use, which exacerbates scale accumulation. Cleaning existing plate heat exchangers requires workers to disassemble the stacked heat exchange plates for individual cleaning. The complete disassembly of the heat exchanger bolts and the manual cleaning and reinstallation of the individual plates consume a lot of time and affect the normal operation of the equipment.
[0003] For example, CN202311793124.5 discloses a plate heat exchanger that uses a movable mechanism mounted above the heat exchanger to move a high-pressure water gun to rinse the edges of the heat exchange plates. The roller brush in the cleaning component at the edge of the heat exchanger can only clean the edge part of the heat exchange plates. Since the plates are tightly squeezed together, there is no structure or function for disassembling and separating the heat exchange plates. In addition, the corrugated structure between the heat exchange plates makes it impossible for the horizontal water flow to powerfully clean the grooves formed by the stamping of the plates. Moreover, the impact of ordinary water flow on hard scale such as calcium carbonate and calcium sulfate is greatly reduced, resulting in low descaling efficiency. This makes the feasibility of this solution questionable. Furthermore, cleaning the gaps between the plates separately by using optical detection in conjunction with a high-pressure water gun would waste a lot of water resources. Therefore, in the field of plate heat exchangers with scaling and corrosion, practical and efficient technical solutions are still needed. Summary of the Invention
[0004] The purpose of this invention is to provide a corrosion-resistant symmetrical flow channel plate heat exchanger to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, the present invention provides the following technical solution: a corrosion-resistant symmetrical flow channel plate heat exchanger, specifically comprising a fixed clamping plate, a horizontal storage hopper, and a vibration mechanism. Guide rods are fixedly installed on the front and rear sides of the top surface of the fixed clamping plate. A movable clamping plate is disposed above the fixed clamping plate. A sleeve rod is fixedly connected to the top surface of the movable clamping plate. A lifting threaded shaft is rotatably connected to the center of the top surface of the movable clamping plate. Four sets of connecting flanges are welded to the top of the movable clamping plate. A bent flange pipe is connected to the top of the connecting flanges via flange connections. An inductive corrosion probe is threadedly connected to the top of the movable clamping plate. A column plate is fixedly connected to the top of the guide rods. A through hole is vertically penetrating the interior of the column plate. A sleeve is provided at the top of the through hole, and the sleeve rod slides inside the sleeve. Two sets of handles are fixedly connected to the top of the column plate. A lifting reducer is provided at the center of the column plate. The lifting reducer is driven by the lifting threaded shaft. A handwheel is installed on the left side of the lifting reducer. Clamping bolts are provided on the left and right sides of the fixed clamping plate and the movable clamping plate. A wastewater pipe is fixedly connected to the bottom of the horizontal storage hopper. An electric valve A is connected to the left end of the wastewater pipe through a flange. An industrial control host is provided on the right side of the horizontal storage hopper. The inductive corrosion probe and the circuit of electric valve A are connected to the industrial control host. The vibrating mechanism is provided inside the horizontal storage hopper. The vibrating mechanism includes a paddle mechanism and a vibration mechanism.
[0006] By adopting the above technical solution, after cleaning, the clamping bolts can be removed, and the lifting reducer handwheel can be turned to drive the lifting threaded shaft to rotate. Through cooperation with the sleeve rod, the movable clamping plate can be moved horizontally upward, so that it can be stably separated from the fixed clamping plate. After cleaning, the lifting reducer handwheel is rotated in the opposite direction to drive the movable clamping plate to reset. The user can then directly reinstall the clamping bolt nuts, saving the time of manually disassembling and assembling the clamping bolts and heat exchange fins in the traditional cleaning method, thus improving cleaning efficiency.
[0007] Optionally, a titanium alloy heat exchange plate is provided between the fixed clamping plate and the movable clamping plate. A base is fixedly connected to the vertical surface of the front end of the fixed clamping plate, the movable clamping plate, and the column plate. The bottom of the fixed clamping plate is provided with four sets of pipe flanges. The bottom of the pipe flanges is connected to four sets of concave blind plates through flange connections. The fixed clamping plate is located inside the horizontal storage hopper. A grooved base is fixedly installed at the bottom of the inner side of the horizontal storage hopper. The groove shape at the top of the grooved base matches the shape of the bottom end of the clamping bolt. A horizontal folded edge is fixedly connected to the top edge of the horizontal storage hopper. A lifting ring is fixedly connected to the top of the folded edge. A vise with a handwheel is fixedly installed at the bottom of the folded edge.
[0008] By adopting the above technical solution, the fixing clamping plate is placed downwards and placed inside the horizontal storage hopper. After inserting the bottom of the clamping bolt into the grooved base, the heat exchanger body is positioned. The bent flange pipe is connected to the heat exchange pipeline for heat exchange. The scale condition of the heat exchanger is monitored regularly by the industrial control host in conjunction with sensors and inductive corrosion probes.
[0009] Optionally, a three-way pipe is provided on the right side of the horizontal storage hopper, and a check valve is provided on the left side of the three-way pipe via a flange. The left end of the check valve is connected to the inside of the horizontal storage hopper via a flange pipe. An electric valve B is provided on the top of the three-way pipe via a flange. A medicine tank is provided on the top of the electric valve B via a flange. A support is provided at the bottom of the medicine tank. The circuit of the electric valve B is connected to the industrial control host, and the end of the three-way pipe is connected to the pressurization pump pipeline.
[0010] By adopting the above technical solution, the descaling agent is pre-poured into the reagent tank for storage. When the cleaning mode is started, the external liquid flows into the storage tank through the three-way pipe. The industrial control host controls the pressurization pump to input the external water flow into the horizontal storage tank through the three-way pipe. At the same time, the electric valve B is opened intermittently, so that the descaling agent in the reagent tank mixes into the three-way pipe. After the diluted descaling agent enters the horizontal storage tank, it dissolves the scale attached to the surface of the separated heat exchange plates by soaking.
[0011] Optionally, the pry mechanism includes a carrying bracket with a handle at the top, the bottom horizontal surface of the carrying bracket being in contact with the top surface of the folded edge, and the bottom plate of the carrying bracket being clamped and fixed by the vise with a handwheel.
[0012] By adopting the above technical solution, when it is necessary to convert the heat exchanger body to a horizontal or vertical position, the user can operate the vise with a handwheel to control the clamping and fixing of the folding edge and the carrying bracket. After the clamping of the folding edge and the carrying bracket is released, the user can hold the handle and lift the carrying brackets on both sides directly.
[0013] Optionally, the carrying bracket has side supports on both sides, and the bottom of the side supports is connected to an integral base by bolts. The bottom of the integral base contacts the bottom edge of the inner side of the horizontal storage hopper. A rack is installed on the side of the carrying bracket, and a reciprocating screw is fixedly installed at the bottom of the carrying bracket. A drive mechanism is provided at the top of the reciprocating screw, and the drive mechanism is fixedly installed on the side of the carrying bracket. A slide is slidably connected to the inner side of the reciprocating screw, and a working bracket is fixedly installed on the side of the slide.
[0014] By adopting the above technical solutions, in the cleaning mode, the industrial control host controls the reciprocating screw to drive the slide table and working support to move back and forth in the horizontal direction.
[0015] Optionally, the working bracket is rotatably connected to drive gears on both sides, the drive gears meshing with racks, and a linkage telescopic mechanism is provided on the side of the drive gears. The drive gears are coaxially connected to the eccentric wheels of the linkage telescopic mechanism, and the ends of the linkage telescopic mechanism are connected to telescopic rods via connecting rods. The telescopic rods are slidably connected within the interlayers at both ends of the working bracket, and the ends of the telescopic rods are fixedly connected to flat plates. Flywheel mechanisms are provided on both sides of the working bracket, and the outer rings of the flywheel mechanisms rotate inside the left and right sides of the working bracket. The inner rings of the ratchet of the flywheel mechanisms are coaxially connected to driven shafts, and driven gears are coaxially connected to driven shafts. Transmission gears are rotatably connected to both sides of the working bracket, one side of the transmission gear meshing with the drive gear, and the other side of the transmission gear meshing with the driven gear. An inner shaft is provided on the inner side of the working bracket, and the left and right ends of the inner shaft are coaxially connected to the outer rings of the flywheel mechanism. Flexible levers are fixedly connected to the curved surfaces of the inner shaft.
[0016] By adopting the above technical solution, when the working support moves vertically downward, the drive gear rotates during the vertical movement and meshing with the rack. The drive gear simultaneously drives the transmission gear meshing on the other side to rotate, and the transmission gear drives the driven gear with a smaller diameter to rotate. The driven gear and the inner shaft drive the coaxial ratchet to rotate. During the downward movement, the ratchet rotates inside the flywheel mechanism, preventing the driven shaft and the flexible lever from rotating. When the working support reaches the bottom and moves upward, the drive gear rotates counterclockwise, and through the transmission gear, the driven gear on the other side rotates counterclockwise. At this time, the ratchet and the flywheel mechanism are internally limited, causing the outer ring of the flywheel mechanism and the coaxial driven shaft to rotate counterclockwise. This achieves the upward pushing and separation of the heat exchange plates during the upward movement of the slide table. After the descaling agent for cleaning is injected, it is convenient for the heat exchange plates to separate and contact with the agent. The gap between the plates is generated, which is conducive to the horizontal dispersing and separation of the dirt between the plates.
[0017] Optionally, the vibration mechanism is located on the front and rear sides inside the horizontal storage hopper. The vibration mechanism includes a corrugated plate, which is disposed on the front and rear sides inside the horizontal storage hopper. The top of the corrugated plate is provided with a perforated flexible plate surface, which is fixed to the folded edge by bolts. One side of the corrugated plate is provided with fins, and an ultrasonic transducer is fixedly installed on the other side of the corrugated plate. The ultrasonic transducer circuit is connected to the industrial control host.
[0018] By adopting the above technical solutions, the industrial control host controls the ultrasonic transducer to start, so that it can oscillate the cleaning liquid inside the horizontal storage tank at high frequency during the cleaning process, which helps the descaling agent react with the scale on the heat exchange plate and helps the dirt attached to the surface of the titanium alloy heat exchange plate to fall off and disperse.
[0019] In summary, the present invention provides a corrosion-resistant symmetrical flow channel plate heat exchanger, which includes at least one of the following beneficial effects:
[0020] 1. The resistance change is monitored by elastic contact of the heat exchanger plate with an inductive corrosion probe, and the scaling rate of the medium is intelligently analyzed by the industrial control host, which makes it convenient for maintenance personnel to monitor the scaling of the heat exchanger plate inside the heat exchanger through the industrial control host.
[0021] 2. The industrial control host controls the operation of the pressurization pump to input external water into the horizontal storage tank through the three-way pipe. At the same time, the electric valve B opens intermittently, allowing the descaling agent inside the chemical tank to mix into the three-way pipe. After the diluted descaling agent enters the horizontal storage tank, it dissolves the scale attached to the surface of the separated heat exchange plates through soaking, which facilitates the automatic soaking and softening of the scale on the plate heat exchanger plates.
[0022] 3. The industrial control host intelligently analyzes and monitors the scale content of the heat exchanger. When the warning value is reached, the host controls the electric valve at the end of the bent flange pipe and the water pump in the heat exchange pipeline to shut down. Then, the program controls the motor of the drive mechanism to run, which drives the lead screw to rotate, thereby driving the slide to move vertically back and forth. During the process of the slide moving the working support upward, the drive gear rotates during the vertical movement and meshes with the rack. At the same time, the drive gear drives the connecting rod telescopic mechanism on the side to run. Through the cooperation of the eccentric wheel and the connecting rod, the telescopic rod moves horizontally back and forth. At this time, during the up and down movement of the slide, the two flat plates on both sides reciprocate to clamp the left and right edges of the titanium alloy heat exchange plate. With the help of the clamping bolts that are not completely removed, the heat exchange plate can be positioned and reset during cleaning and separating the stacked heat exchange plates. This facilitates the rapid assembly of the heat exchange plates in the heat exchanger during descaling.
[0023] 4. Through structural design, the outer ring of the flywheel mechanism and the driven shaft coaxial with it rotate counterclockwise, realizing the upward pushing and separation of the heat exchange plates during the upward translation of the slide table. After the descaling agent for cleaning is injected, it is convenient for the heat exchange plates to separate and come into contact with the agent. The gap between the plates is generated, which is conducive to the horizontal flushing and separation of the dirt between the plates without direct manual operation.
[0024] 5. After the user turns the handwheel to loosen the vise with the handwheel, they can lift the handles upwards with both hands to remove the two-sided diaphragm mechanism directly from inside the horizontal storage hopper. Then, they can grasp the handles on both sides of the top of the column plate to remove the plate heat exchanger body. After removing the bent flange tube from the movable clamping plate, they can replace it with a flat blind plate. At the same time, they can remove the concave blind plate of the fixed clamping plate and connect the pipe of the fixed clamping plate with the heat exchange pipe. This allows for quick conversion between vertical and horizontal configurations of the heat exchanger, making it convenient to adapt to different usage scenarios based on available space.
[0025] 6. Through the vertical lifting structure of the heat exchanger and the cooperation of the vibrating mechanism, when cleaning, after removing the clamping bolts, the lifting reducer and the sleeve rod are rotated to move the movable clamping plate horizontally upward, so that it is stably separated from the fixed clamping plate. After cleaning, the handwheel of the lifting reducer is rotated in the opposite direction to reset the movable clamping plate. The user can then directly reinstall the nuts of the clamping bolts, saving the time of manually disassembling and assembling the clamping bolts and heat exchanger plates in the traditional cleaning method, thus improving cleaning efficiency.
[0026] 7. By monitoring data from the water level sensor and coordinating with the control system, the industrial control host can monitor and control the clear liquid level inside the horizontal storage tank. When the plate heat exchanger leaks, the liquid enters the horizontal storage tank for buffering. The water level sensor detects this and the industrial control host can control the heat exchange pipeline pump to stop immediately and issue an alarm signal, facilitating maintenance personnel to repair the leak as soon as possible. In addition, the structure of the horizontal storage tank can prevent high-temperature media from spraying outward from the gaps between the plates and causing injury to workers in the event of an external leak.

[0043] Please see Figure 1-9Embodiment 1 of the present invention: The present invention provides a corrosion-resistant symmetrical flow channel plate heat exchanger, including a fixed clamping plate 1, a horizontal storage hopper 2, and a vibrating mechanism. Guide rods 101 are fixedly installed on the front and rear sides of the top surface of the fixed clamping plate 1. A movable clamping plate 102 is provided above the fixed clamping plate 1. A sleeve rod 1021 is fixedly connected to the top surface of the movable clamping plate 102.

The fixed clamping plate 1 and the movable clamping plate 102 are connected by clamping bolts 104. Titanium alloy heat exchange fins 105 are provided between plates 102. A base 106 is fixedly connected to the vertical front end of the fixed clamping plate 1, movable clamping plate 102, and column plate 103. The bottom of the fixed clamping plate 1 has four sets of connecting flanges, and the bottom of each connecting flange is connected to four sets of recessed blind plates 107. The fixed clamping plate 1 is placed downwards and inserted into the horizontal storage hopper 2. The heat exchanger body is positioned after the bottom of the clamping bolts 104 are inserted into the grooved base 201. The bent flange pipe 1023 is connected to the heat exchange pipeline for heat exchange. Heat exchange is then performed via the industrial control host 205 in conjunction with sensors and inductive corrosion probe 102. 4. Monitor the scale condition of the heat exchanger regularly. After cleaning, remove the clamping bolt 104 and rotate the handwheel of the lifting reducer 1032 to drive the lifting threaded shaft 1022 to rotate. Through the cooperation of the sleeve rod 1021, the shaft drives the movable clamping plate 102 to move horizontally upward, so that it is stably separated from the fixed clamping plate 1. After cleaning, rotate the handwheel of the lifting reducer 1032 in the opposite direction to drive the movable clamping plate 102 to reset. The user can directly put the nut of the clamping bolt 104 back on, saving the time of manually disassembling and assembling the clamping bolt 104 and heat exchanger plates in the traditional cleaning method, thus improving cleaning efficiency.
[0044] Reference Figures 5 to 7A clamping plate 1 is fixed inside the horizontal storage hopper 2. A grooved base 201 is fixedly installed at the bottom inside the horizontal storage hopper 2. The groove shape at the top of the grooved base 201 matches the shape at the bottom of the clamping bolt 104. A horizontal folded edge 202 is fixedly connected to the top edge of the horizontal storage hopper 2. A lifting ring is fixedly connected to the top of the folded edge 202. A vise 203 with a handwheel is fixedly installed at the bottom of the folded edge 202. A wastewater pipe 204 is fixedly connected to the bottom of the horizontal storage hopper 2. An electric valve A2041 is connected to the left end of the wastewater pipe 204 through a flange. An industrial control host 205 is installed on the right side of the horizontal storage hopper 2. The circuits of the inductive corrosion probe 1024 and the electric valve A2041 are connected to the industrial control host 205. The resistance change is monitored by the elastic contact of the inductive corrosion probe 1024 with the heat exchange plate, which facilitates the maintenance personnel to monitor the scaling of the heat exchange plate inside the heat exchanger.
[0045] Reference Figures 1 to 5 The tremor mechanism is located inside the horizontal storage hopper 2. The tremor mechanism includes a pawl mechanism and a vibration mechanism. A three-way pipe 3 is located on the right side of the horizontal storage hopper 2. A check valve 301 is connected to the left side of the three-way pipe 3 via a flange.

The end of the three-way pipe 3 is connected to the pressurization pump pipeline. The industrial control host 205 controls the pressurization pump to input external water flow from the three-way pipe 3 into the interior of the horizontal storage hopper 2. At the same time, the electric valve B302 opens intermittently, allowing the descaling agent inside the chemical tank 303 to mix into the three-way pipe 3. After the diluted descaling agent enters the interior of the horizontal storage hopper 2, it dissolves the scale attached to the surface of the separated heat exchange plates through soaking.
[0046] Reference Figures 3 to 9The lever mechanism includes a carrying bracket 4, with a handle 401 at the top. The bottom horizontal surface of the carrying bracket 4 is in contact with the top surface of the folded edge 202. The bottom plate of the carrying bracket 4 is clamped and fixed by a vise 203 with a handwheel. Side brackets 402 are provided on both sides of the carrying bracket 4. The bottom of the side brackets 402 is bolted to an integral base 403. The bottom of the integral base 403 contacts the inner bottom edge of the horizontal storage hopper 2. A rack 404 is installed on the side of the carrying bracket 4. Depending on the scenario and the size of the current installation area, when the heat exchanger needs to be installed vertically... After the user turns the handwheel to release the vise 203, they can lift the two side levers directly from the horizontal storage hopper 2 by holding the handles 401 with both hands.

The bent flange pipe 1023 can be removed from the movable clamping plate 102 and replaced with a flat blind plate. At the same time, the concave blind plate 107 of the fixed clamping plate 1 can be removed. The pipe of the fixed clamping plate 1 can be connected to the heat exchange pipe.

[0047] Reference Figures 3 to 9 A reciprocating screw 5 is fixedly installed at the bottom of the portable support 4. A drive mechanism 501 is installed at the top of the reciprocating screw 5. The drive mechanism 501 is fixedly installed on the side of the portable support 4. A slide table 502 is slidably connected to the inner side of the reciprocating screw 5. A working support 503 is fixedly installed on the side of the slide table 502. A drive gear 504 is rotatably connected to the left and right sides of the working support 503. The drive gear 504 meshes with a rack 404. A connecting rod telescopic mechanism 5041 is provided on the side of the drive gear 504. The drive gear 504 and the eccentric wheel of the connecting rod telescopic mechanism 5041 are coaxially connected. A telescopic rod is connected to the end of the connecting rod telescopic mechanism 5041 through a connecting rod. The telescopic rod is slidably connected in the interlayer at both ends of the working support 503. A flat plate 5042 is fixedly connected to the end of the telescopic rod. Flywheel mechanisms 6 are provided on the left and right sides of the working support 503. The heat exchanger water is intelligently analyzed and monitored by the industrial control host 205. When the scale content reaches the warning value, the main unit controls the electric valve at the end of the bent flange pipe 1023 and the water pump in the heat exchange pipeline to shut down. Then, the program controls the motor of the drive mechanism 501 to run, which drives the lead screw to rotate, thereby driving the slide table 502 to move vertically back and forth. During the process of the slide table 502 driving the working bracket 503 to move upward, the drive gear 504 rotates during the vertical movement and meshes with the rack 404. At the same time, the drive gear 504 drives the side connecting rod telescopic mechanism 5041 to run. Through the cooperation of the eccentric wheel and the connecting rod, the telescopic rod is driven to reciprocate and extend. At this time, during the up and down movement of the slide table 502, the two side plates 5042 reciprocate to clamp and position the left and right edges of the titanium alloy heat exchange plate 105. This can position and reset the heat exchange plate during cleaning and separating the stacked heat exchange plates, which is convenient for quick assembly of the heat exchanger during descaling.
[0048] Reference Figures 2 to 9 The outer ring of the flywheel mechanism 6 rotates inside the left and right sides of the working bracket 503. The inner ring of the ratchet of the flywheel mechanism 6 is coaxially connected to the driven shaft 6012, and the driven shaft 6012 is coaxially connected to the driven gear 6011. The two sides of the working bracket 503 are rotatably connected to the transmission gear 505. One side of the transmission gear 505 meshes with the drive gear 504, and the other side of the transmission gear 505 meshes with the driven gear 6011. An inner shaft 601 is provided inside the working bracket 503. The left and right ends of the inner shaft 601 are coaxially connected to the outer ring of the flywheel mechanism 6. The curved surface of the inner shaft 601 is fixedly connected to the flexible lever 6013. As needed, the protruding parts at the left and right ends of the working bracket 503 can be disassembled and reassembled by installing quick-release plates or other quick-disassembly and assembly components. In the cleaning mode, when the working bracket 503 moves vertically downward, the drive gear 504 rotates during the vertical movement process and meshes with the rack 404. 4. Simultaneously, the transmission gear 505 meshing on the other side rotates. The transmission gear 505 drives the driven gear 6011 with a smaller diameter to rotate. The driven gear 6011 and the inner shaft 601 drive the coaxial ratchet to rotate. During the downward movement, the ratchet rotates inside the flywheel mechanism 6, so that the driven shaft 6012 and the flexible lever 6013 do not rotate. When the working bracket 503 reaches the bottom and moves upward, the drive gear 504 rotates counterclockwise in the opposite direction. Through the transmission gear 505, the driven gear 6011 on the other side rotates counterclockwise. At this time, the ratchet is limited inside the flywheel mechanism 6, so that the outer ring of the flywheel mechanism 6 and the coaxial driven shaft 6012 rotate counterclockwise. This realizes the upward pushing and separation of the heat exchange plates during the upward movement of the slide table 502. After the descaling agent for cleaning is injected, it is convenient for the heat exchange plates to separate and contact with the agent. The gap between the plates is generated, which is conducive to the horizontal separation of the dirt between the plates.
[0049] Reference Figures 1 to 8 The vibration mechanism is located on the front and rear sides inside the horizontal storage hopper 2. The vibration mechanism includes a corrugated plate 7. The corrugated plate 7 is set on the front and rear sides inside the horizontal storage hopper 2. The top of the corrugated plate 7 is provided with a perforated flexible plate surface. The perforated flexible plate surface is fixed to the folded edge 202 by bolts. One side of the corrugated plate 7 is provided with fins. An ultrasonic transducer 701 is fixedly installed on the other side of the corrugated plate 7. The circuit of the ultrasonic transducer 701 is connected to the industrial control host 205. The industrial control host 205 controls the ultrasonic transducer 701 to start, so that it oscillates the cleaning liquid inside the horizontal storage hopper 2 at high frequency during the cleaning process, which helps the descaling agent react with the scale on the heat exchange plate and helps the dirt attached to the surface of the titanium alloy heat exchange plate 105 to fall off and disperse.
[0050] Example 2: Based on Example 1, the control circuit of the industrial control host 205 is also connected to the heat exchange pipeline pump body. The horizontal storage hopper 2 is equipped with a water level sensor and a flow promoter connected to the data of the industrial control host 205. During the cleaning process, the flow promoter pushes the liquid inside the storage hopper and facilitates the flow of scale between the plates during the plate movement. By monitoring the data through the water level sensor and cooperating with the control system, the industrial control host 205 can monitor and control the clear liquid level inside the horizontal storage hopper 2. When the plate heat exchanger leaks, the liquid enters the horizontal storage hopper 2 for buffering. The water level sensor detects this and can cause the industrial control host 205 to control the heat exchange pipeline pump body to stop suddenly and issue an alarm signal, which is convenient for maintenance personnel to repair immediately.
[0051] The specific usage and function of this embodiment: When using this invention, the heat exchanger body is tilted so that the fixing clamping plate 1 faces downwards, and placed inside the horizontal storage hopper 2. After inserting the bottom of the clamping bolt 104 into the grooved base 201, the heat exchanger body is positioned. After connecting the bent flange pipe 1023 to the heat exchange pipeline, heat exchange is performed. The industrial control host 205, in conjunction with sensors and inductive corrosion probe 1024, monitors the scale condition of the heat exchanger at regular intervals. The industrial control host 205 monitors the scale content of the heat exchanger. When the warning value is reached, maintenance personnel can set a timed or manual start to activate the cleaning mode. The host controls the electric valve at the end of the bent flange pipe 1023 and the water pump of the heat exchange pipeline to shut down. The subsequent program controls the motor of the drive mechanism 501 to rotate, causing the lead screw to rotate, which in turn drives the slide table 502 to move vertically reciprocally. During the upward translation of the working bracket 503 by the slide table 502, the drive gear 504 rotates during its vertical movement, meshing with the rack 404. Simultaneously, the drive gear 504 drives the side linkage telescopic mechanism 5041 to rotate, which, through the cooperation of the eccentric wheel and the connecting rod, drives the telescopic rod to reciprocate. At this time, during the up-and-down movement of the slide table 502, the two side plates 5042 reciprocate to clamp and position the left and right edges of the titanium alloy heat exchanger 105. During the vertical downward movement of the working bracket 503, the drive gear 504... During the meshing transmission with the rack 404, the drive gear 504 rotates, simultaneously driving the transmission gear 505 on the other side to rotate. The transmission gear 505 drives the driven gear 6011 with a smaller diameter to rotate. The driven gear 6011 and the inner shaft 601 drive the coaxial ratchet to rotate. During the downward movement, the ratchet rotates inside the flywheel mechanism 6, preventing the driven shaft 6012 and the flexible lever 6013 from rotating. When the working bracket 503 reaches the bottom and moves upward, the drive gear 504 rotates counterclockwise, which, through the transmission gear 505, causes the driven gear 6011 on the other side to rotate counterclockwise. At this time, the ratchet is limited inside the flywheel mechanism 6, preventing the flywheel mechanism 6 from rotating externally. The ring and its coaxial driven shaft 6012 rotate counterclockwise, realizing the upward movement and separation of the heat exchange plates during the upward translation of the slide table 502. The industrial control host 205 controls the ultrasonic transducer 701 to start, so that it performs high-frequency oscillation on the cleaning liquid inside the horizontal storage tank 2 during the cleaning process, which helps the descaling agent react with the scale on the heat exchange plates and helps the dirt attached to the surface of the titanium alloy heat exchange plate 105 to fall off and disperse. The flow pusher pushes the liquid inside the storage tank during the cleaning process, and facilitates the flow of scale between the plates during the movement of the plates. After the scale flows out through the gaps between the plates and enters the interior of the horizontal storage tank 2, the electric valve A2041 is opened to discharge the wastewater mixed with dirt through the wastewater pipe 204.
