Description

Technical Field

[0001] This utility model relates to the field of heat exchanger technology, and in particular to a heat exchanger that is easy to maintain. Background Technology

[0002] Heat exchangers, as important heat exchange equipment in industrial production, are widely used in chemical, power, pharmaceutical and other fields. In the long-term use of traditional heat exchangers, scale, oil and other deposits are easy to accumulate on the surface of the heat exchange plates, which seriously affects the heat exchange efficiency.

[0003] Currently, the main types of heat exchangers on the market are: shell and tube heat exchangers, plate heat exchangers, and coaxial heat exchangers. The maintenance process for plate heat exchangers includes first stopping the machine and disconnecting the medium connection, then disassembling the heat exchanger and removing the heat exchange plates one by one, cleaning the heat exchange plates to remove dirt, checking for deformation, cracks, or other damage to the heat exchange plates, replacing damaged heat exchange plates and aged gaskets, and finally reassembling them in the correct order.

[0004] The above-mentioned existing technical solutions have the following drawbacks: when repairing the heat exchanger, the heat exchange plates need to be completely disassembled, which is not only labor-intensive but also time-consuming. Utility Model Content

[0005] The purpose of this invention is to provide a heat exchanger that is easy to maintain, so as to solve the problems existing in the prior art.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0007] A heat exchanger that is easy to maintain, including a base plate, and further including:

[0008] Mounting plate, which is detachably mounted vertically on the left side of the base plate. The top of the mounting plate extends to the right with an integrally formed support plate. The front and rear sides of the mounting plate are equally spaced with multiple first clearance openings along the height direction. The center of the bottom right side of the mounting plate extends to the right with a crossbeam. The left end of the mounting plate has a first circular hole that runs through the left and right sides.

[0009] A movable plate is provided, which is parallel to the mounting plate. A through hole is provided at the center of the bottom end of the mounting plate. The right end of the crossbeam passes through and extends to the outside of the through hole. The movable plate and the crossbeam are slidably installed. Multiple second clearance openings along the height direction are provided at equal intervals on the front and rear sides of the movable plate. A second circular hole that runs through the left and right sides is opened at the right end of the movable plate. The same water pipe is detachably installed in the first and second circular holes. Multiple heat exchange fins are sleeved on the water pipe. The bottom end of the heat exchange fins is snapped into the top end of the crossbeam.

[0010] The locking module is provided in two parts, which are screwed to the top of the base plate. The two locking modules are symmetrically arranged about the top of the crossbeam. The locking module is used to lock the moving plate.

[0011] A connecting component, the connecting component being used to abut against the heat exchange plate, the connecting component being snapped into the first clearance port and the second clearance port;

[0012] A cleaning module is fixedly installed at the bottom of the support plate and is used to clean the heat exchange fins.

[0013] By adopting the above technical solution, when the heat exchanger needs maintenance, the water pipe is removed from the mounting plate and the moving plate. Then, the position of the connecting assembly and the locking module is adjusted to move the moving plate away from the mounting plate. The locking module then locks the moving plate onto the crossbeam. The connecting assembly locks the heat exchanger between the moving plate and the mounting plate to prevent the heat exchanger from slipping off the crossbeam. Then, the heat exchanger is moved to increase the distance between adjacent heat exchangers. Next, the cleaning module is activated to rinse the heat exchanger. Throughout the process, the staff does not need to remove the heat exchangers one by one from the crossbeam; the heat exchangers can be cleaned directly on the crossbeam. After the heat exchangers are cleaned, the staff can directly inspect and maintain them, achieving the goal of saving time and effort throughout the maintenance process.

[0014] In a further embodiment, the cleaning module includes:

[0015] A movable rod unit, wherein multiple sets of the movable rod units are arranged at equal intervals, and each movable rod unit consists of at least one vertical rod, the bottom of which is fixedly connected to a rectangular plate;

[0016] The nozzles are provided in multiple ways, and the multiple nozzles are fixedly installed on the left and right sides of the rectangular plate;

[0017] And an isolation strip, which is sleeved on the bottom end of the vertical rod, and is used to isolate two adjacent heat exchange fins.

[0018] By adopting the above technical solution, the isolation strip keeps a certain distance between adjacent heat exchange plates. Then, the vertical rod is activated to move up and down, which in turn drives the nozzle on the rectangular plate at the bottom of the vertical rod to move up and down, so that the nozzle can rinse the heat exchange plates close to its nozzle direction.

[0019] In a further embodiment, the locking module includes:

[0020] The fixing block has a centrifugal extension extending from its bottom periphery. The top of the extension has multiple through holes that pass through vertically. Locking bolts are inserted into the through holes. The top of the fixing block has a downward groove along its length. The front and rear sides of the groove are completely open. The left and right ends of the groove have threaded holes that pass through horizontally. The interior of the groove has a downward guide groove along its length.

[0021] The sliding plate is provided in two parts, which are slidably installed in the guide groove. One sliding plate is located on the left side of the moving plate, and the other sliding plate is located on the right side of the moving plate.

[0022] The screw unit includes a first screw and a second screw. The two ends of the first screw pass through and extend to the outside of the threaded hole at the left end of the groove. The right end of the first screw is fixedly connected to a sliding plate located on the left side of the moving plate. The two ends of the second screw pass through and extend to the outside of the threaded hole at the right end of the groove. The left end of the second screw is fixedly connected to a sliding plate located on the right side of the moving plate.

[0023] By adopting the above technical solution, the rotating screw unit can drive the two sliding plates to move linearly in the left and right directions along the guide groove. When it is necessary to move the moving plate to the right, the first screw is rotated to drive the sliding plate on the right side of the moving plate to move to the right. After the sliding plate on the right side of the moving plate moves to the appropriate position, the moving plate slides to the right along the crossbeam. After the moving plate is moved to the position where it is in contact with the sliding plate on the right side of the moving plate, the second screw is rotated to drive the sliding plate on the left side of the moving plate to move to the right, so that the moving plate is finally clamped between the two sliding plates.

[0024] In a further embodiment, the connecting assembly consists of multiple threaded rods, with a first internal threaded sleeve fitted on the left side of the threaded rod and a second internal threaded sleeve passing through the right end of the threaded rod. Both the first and second internal threaded sleeves are screwed to the threaded rods. The outer diameter of the ends of the first and second internal threaded sleeves that are close to each other is smaller than the outer diameter of the ends of the first and second internal threaded sleeves that are far apart from each other.

[0025] By adopting the above technical solution, since both the first internal threaded sleeve and the second internal threaded sleeve are screwed to the threaded rod, the distance between the second internal threaded sleeve and the first internal threaded sleeve can be adjusted by rotating the second internal threaded sleeve. The left end of the first internal threaded sleeve can provide a rightward support force for the mounting plate to prevent the mounting plate from tilting.

[0026] In a further embodiment, a handle is fixedly installed at the opposite ends of the first screw and the second screw.

[0027] By adopting the above technical solution, the design of fixing handles at the left end of the first screw and the right end of the second screw respectively facilitates the rotation of the first screw and the second screw by the staff.

[0028] In a further embodiment, the nozzle is a multi-head nozzle, and the inlet of the multi-head nozzle is connected to a high-pressure water pump.

[0029] By adopting the above technical solution, multi-head nozzles can expand the rinsing area of ​​the heat exchange fins.

[0030] In summary, this utility model has the following beneficial effects:

[0031] 1. By using the connecting components and locking modules, when the heat exchanger needs maintenance, the water pipes are removed from the mounting plate and the moving plate. Then, the positions of the connecting components and locking modules are adjusted, moving the moving plate away from the mounting plate. The locking module then locks the moving plate onto the crossbeam. The connecting components lock the heat exchanger between the moving plate and the mounting plate, preventing the heat exchanger from slipping off the crossbeam. The heat exchanger is then moved to increase the distance between adjacent heat exchangers. The cleaning module is then activated to rinse the heat exchanger. Throughout the process, workers do not need to remove each heat exchanger from the crossbeam individually; the heat exchangers can be cleaned directly on the crossbeam. After cleaning, workers can directly inspect and maintain the heat exchangers, saving time and effort throughout the maintenance process. Attached Figure Description

The bottom ends of the heat exchange fins 4 are snapped onto the top of the crossbeam. Two locking modules 6 are provided, screwed onto the top of the base plate 1. The two locking modules 6 are symmetrically arranged about the top of the crossbeam 3. The locking modules 6 are used to lock the moving plate 5. A connecting component 7 is used to abut the heat exchange fins 4 and is snapped into the first and second clearance openings. A cleaning module 8 is fixedly installed on the support. At the bottom of the support plate, the cleaning module 8 is used to clean the heat exchange plates 4. The cleaning module 8 includes a moving rod unit 81, a nozzle 82, and an isolation strip 83.

A rectangular plate 84 is fixedly connected to the bottom of the vertical rod. Multiple nozzles 82 are provided. Multiple nozzles 82 are fixedly installed on the left and right sides of the rectangular plate 84. The nozzles 82 are multi-head nozzles. The inlet of the multi-head nozzles is connected to a high-pressure water pump. The isolation strip 83 is sleeved on the bottom end of the vertical rod. The isolation strip 83 is used to isolate two adjacent heat exchange plates 4.The locking module 6 includes a fixing block 61, a sliding plate 62, and a screw unit 63. The bottom periphery of the fixing block 61 has a centrifugal extension edge, and the top of the extension edge has multiple through holes extending vertically. Locking bolts are inserted into these through holes and screwed into one of the locking holes on the top of the base plate. The top of the fixing block 61 has a downward-facing groove along its length, with the front and rear sides of the groove completely open. The left and right ends of the groove each have a through-hole. The interior of the groove has a downward-facing guide groove along its length.

[0041] Specific implementation process: When it is necessary to maintain the heat exchanger 4, first rotate the second internal threaded sleeve 10 to move it to the right along the threaded rod 71. After moving it to the appropriate position, remove the water pipe completely from the mounting plate 2 and the moving plate 5. At this time, the heat exchanger 4 is still attached to the crossbeam 3, but the constraint of the water pipe has been released. Next, rotate the handle located on the right side of the moving plate 5 to move the first screw 631 to the right, thereby driving the sliding plate 62 on the first screw 631 to the appropriate position. Then slide the moving plate 5 to the right along the crossbeam 3 until the moving plate 5 and the sliding plate 62 on its right side are in contact. Then rotate the handle located on the left side of the moving plate 5 to move the second screw 632 to the right, thereby driving the sliding plate 62 on the second screw 631 to the appropriate position. The sliding plate 62 and the moving plate 5 are attached together, so that the moving plate 5 is finally clamped between the sliding plate 62 and the fixed block 61. Then, the staff moves the heat exchange plate 4 to increase the distance between adjacent heat exchange plates 4. Then, the vertical rod is started to move downward, and the staff manually adjusts the spacer strip 83 to insert between adjacent heat exchange plates 4 to maintain a fixed distance. Then, the high-pressure water pump is started, and the water flows through the nozzle 82 to form a high-pressure water mist. By controlling the vertical rod to retract up and down, the rectangular strip 84 is moved up and down, so that the nozzle 82 rinses and removes dirt along the surface of the heat exchange plate 4. After cleaning, the high-pressure water pump is turned off, and the staff checks the cleanliness and integrity of the surface of the heat exchange plate 4. Damaged parts are repaired. After the repair is completed, the above process is reversed to restore the original arrangement of the heat exchange plate 4.
