Description

Technical Field

[0001] The invention relates to the technical field of plate heat exchanger production, in particular to a pressing and assembling device for plate sheets of a plate heat exchanger. Background Art

[0002] Plate heat exchanger plates are specially used in plate heat exchangers to isolate media and perform heat exchange. Each plate contains two parts: the metal plate is a metal sheet pressed with corrugations, sealing grooves and corner holes. The metal plate is an important heat transfer element. The corrugations can not only enhance heat transfer, but also increase the rigidity of the thin plate, thereby improving the pressure bearing capacity of the plate heat exchanger. The sealing gasket is installed in the gasket groove along the periphery of the plate to seal the periphery between the plates to prevent fluid leakage. According to the design requirements, a part of the corner holes of the plate is sealed to allow the cold and hot liquids to flow according to their respective flow channels. According to the requirements of plate heat exchanger production, the thick steel plates on both sides of the heat exchanger plates need to be tightened by bolts to complete the compression process of multiple sets of plates and sealing rings of the plate heat exchanger. The compression process of multiple sets of plates of the heat exchanger needs to compress the plates to the process thickness by manually tightening the bolts multiple times to ensure the airtightness between multiple sets of plates. When assembling a plate heat exchanger, the plates need to be stacked and installed between two sets of mounting plates in sequence, and the positions of multiple plates need to be clamped and fixed by corresponding bolts. During this process, the upper and lower sets of guide rods provided on the mounting plates can guide and constrain the installation of the plates to facilitate the installation of the plates. However, the upper and lower sets of guide rods cannot be adjusted in the vertical direction to clamp and fix the plates. When two adjacent plates are misaligned in the vertical direction, the effective heat exchange area of ​​a single plate will be reduced, thereby affecting the actual heat exchange power of the entire heat exchanger.

[0003] Due to structural design defects, the existing plate heat exchanger plate compression and assembly equipment has the problem that when assembling the plate heat exchanger, two adjacent plates are misaligned in the vertical direction, which affects the actual heat exchange power of the entire heat exchanger, and the plates are compressed by manually tightening bolts multiple times, resulting in low heat exchanger assembly efficiency.

The device fixes the limiting plate on the surface of the fixed seat and fixes the mechanism body on the surface of the pressing seat. It is easy to disassemble and save space when used. After multiple plates are stacked close to the fixed seat, the top and bottom of the pressing seat slide into the guide assembly, the guide assembly connects the winding wheel with the docking assembly, and the guide assembly pushes the pressing seat close to the stacked plates.

[0024] The present invention provides a plate heat exchanger plate pressing and assembling device, which has the following beneficial effects:

[0025] 1. The plate-type heat exchanger plate pressing and assembling equipment has hydraulic pressure introduced into the inside of the liquid pipe, which enables the stabilizing component to clamp the inner side of the plate, and the hoist drives the stabilizing component to approach the fixed seat. There will not be too much friction between the sealing strip and the guide component. The four stabilizing components firmly clamp the plate, and the stabilizing component pushes multiple plates to the fixed seat. The liquid pipe slides back and forth on the inner side of the limit plate. The driving of the stabilizing component avoids uneven force, deflection and dislocation of the plate, and solves the problem that when assembling the plate heat exchanger, the vertical dislocation of two adjacent plates will affect the actual heat exchange power of the entire heat exchanger.

[0026] 2. The plate-type heat exchanger plate pressing and assembling equipment uses a liquid pipe to simultaneously introduce liquid into the four rubber bags, and the liquid squeezes the rubber bags. Due to the limitation of the shrinkage piece, the rubber bags squeeze the curved clamps when they expand, and the curved clamps are pushed away from the rubber bags by the rubber bags to slide. The grooves on the surface of the curved clamps are embedded into the inner side of the plates, so that the plates are evenly clamped by the liquid flow holes on the surface of the plates, and the surface of the guide rails is embedded into the surface of the plates, and the top and bottom of the plates are limited. At the same time, the four sides of the plates are restricted by the curved clamps to move smoothly, and the surface of the plates is evenly stressed, thereby effectively avoiding the deflection and dislocation of the plates.

[0027] 3. The plate-type heat exchanger plate compression and assembly equipment has a rotating shaft at the output end of the motor fixedly connected to a driving gear, which causes the clamping plate assembly to rotate. The clamping plate assembly cooperates with the bolts to push the clamping seat close to the plate. The clamping of the clamping seat and the fixed seat compresses multiple plates to the process thickness. The number of the clamping plate assembly is the same as the number of bolts, so that multiple bolts can be tightened at the same time, which solves the problem of low heat exchanger assembly efficiency caused by manually tightening the bolts multiple times to compress the plates.

[0028] 4. The plate-type heat exchanger plate compression assembly equipment, when the gear body rotates, the compression nut is driven to rotate by the gear body, when the steel strand is pulled and wound, the docking body pushes the mechanism body close to the plate, as the compression nut rotates and moves close to the plate, the compression nut is screwed into the surface of the bolt, the screwing of the compression nut causes the compression seat to compress the plate, and multiple compression nuts are pressed on multiple bolts at the same time, avoiding deformation and damage of the plate due to uneven force when the compression nut is compressed.

[0029] 5. The plate-type heat exchanger plate compression assembly equipment uses an elastic body to prevent the threaded block from hitting the limiter. When the plates are stacked, the compression seat slides into the inner side of the guide rail, pulls the threaded block and screws it into the inner side of the docking body, the winding wheel is driven to rotate, the steel strand shrinks, the lead roller and the pulley support the steel strand, the pulley slides on the inner side of the slide groove, and the compression seat is guided and pushed close to the plate so that multiple plates are compressed, thereby making the plates more efficient when compressed.

[0039] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0040] First embodiment: Figure 1-Figure 3 As shown, the present invention provides a technical solution: a pressing and assembling device for a plate heat exchanger plate, comprising a fixing seat 1; and further comprising:

[0041] A pressing seat 4, which is used to press a plurality of plates against the surface of the fixing seat 1, and a bolt 6 arranged on the surface of the fixing seat 1, the surface of the bolt 6 being sleeved on the inner side of the fixing seat 1, and the pressing seat 4 being arranged opposite to the fixing seat 1;

[0042] An anti-deflection mechanism 2 is fixedly mounted on the surface of the fixing seat 1. The anti-deflection mechanism 2 is used to guide a plurality of plates close to the fixing seat 1. The plates are clamped and driven by the anti-deflection mechanism 2 and are not easily deflected;

[0043] A guide component 3, one end of which is fixedly mounted on the surface of the fixed seat 1, and the guide component 3 is used to limit and guide the plurality of plates, and the surface of the pressing seat 4 is slidably connected to the surface of the guide component 3;

[0044] The assembly mechanism 5 is fixedly installed at the middle position of the surface of the pressing seat 4. The assembly mechanism 5 is used to push the pressing seat 4 toward the plate. The assembly mechanism 5 pushes the pressing seat 4 to be pressed against the fixing seat 1;

[0045] The anti-deflection mechanism 2 includes a gate hoist 22, the inner side of the gate hoist 22 is connected with a stabilizing component 23 through threads, and the stabilizing component 23 is used to clamp the inner side of the plate. The gate hoist 22 controls the stabilizing component 23 to guide the plate to the fixing seat 1;

[0046] The anti-deflection mechanism 2 also includes a liquid pipe 24 and a limit plate 21. The liquid pipe 24 is fixedly installed on the surface of the stabilizing component 23, and the limit plate 21 is fixedly installed on the surface of the fixing seat 1. The surface of the limit plate 21 is rotatably connected to a winding wheel 25, and the surface of the fixing seat 1 near the guide component 3 is rotatably connected to a lead roller 26.

[0047] When in use, there are two guide components 3, and the plate is composed of a metal plate and a sealing strip on the edge. When the plate is put on, the surface of the sealing strip is in close contact with the surface of the guide component 3. When the plate is pushed close to the fixed seat 1, the resistance of the sealing strip is too large, causing the plate to deflect. When a large gap is set between the guide component 3 and the sealing strip, the movement resistance is reduced, but the plates will be misaligned in the vertical direction. In the device, hydraulic pressure is passed into the interior of the liquid pipe 24, and the hydraulic pressure enables the stabilizing component 23 to clamp the inner side of the plate, and the opening and closing machine 22 drives the stabilizing component 23 to approach the fixed seat 1. There will not be too much friction between the sealing strip and the guide component 3. The four stabilizing components 23 firmly clamp the plate, and the stabilizing component 23 pushes multiple plates to the fixed seat 1. The liquid pipe 24 slides back and forth on the inner side of the limit plate 21. The drive of the stabilizing component 23 prevents the plate from being unevenly stressed, deflected and misaligned, and solves the problem that when the plate heat exchanger is assembled, the vertical misalignment of two adjacent plates will affect the actual heat exchange power of the entire heat exchanger.

[0048] Second embodiment: Figure 3 , Figure 4 , Figure 5 As shown, the stabilizing component 23 includes a screw rod 231, the surface of which is connected to the inner side of the gate hoist 22 through a thread, and the end of the screw rod 231 away from the gate hoist 22 is rotatably connected to a fixed shell 232, and the stabilizing component 23 also includes a shrinking piece 233 and an arc-surface clamping block 235, the surface of the shrinking piece 233 is fixedly connected to the inner side of the fixed shell 232, and a rubber bag 234 is fixedly connected to the middle position of the inner side of the fixed shell 232, and the arc-surface clamping block 235 is fixedly installed on the rubber bag 234 on the side close to the arc surface The surface of the rubber bag 234 is connected to the interior of the liquid tube 24. The guide component 3 includes a guide rail 31, which is fixedly installed on the surface of the fixed seat 1. A slide groove 32 is provided on the inner side of the guide rail 31. A steel rope 35 is slidably connected to the inner side of the guide rail 31. The guide component 3 also includes a pulley 33. The surface of the pulley 33 is slidably connected to the inner side of the guide rail 31. The surface of the guide rail 31 is fixedly connected to a limiting body 34. The limiting body 34 is used to limit the pulley 33 to prevent it from slipping.

[0049] When in use, the guide rail 31 guides the plate sealing strip to slide. Manually pushing the plates to overlap can easily cause the plates to deform and deflect. The hoist 22 controls the screw rod 231 to approach or move away from the fixed seat 1. In this process, the fixed shell 232 will be driven to extend into the liquid flow hole on the inner side of the plate. The liquid pipe 24 restricts the movement of the fixed shell 232, so that the fixed shell 232 moves back and forth with the liquid pipe 24. The liquid pipe 24 simultaneously passes liquid into the inside of the four rubber bags 234. The liquid squeezes the rubber bags 234. Due to the shrinkage piece 233 is restricted, the rubber bag 234 expands and squeezes the arc clamp 235, and the arc clamp 235 is pushed by the rubber bag 234 to slide away from the rubber bag 234, and the groove on the surface of the arc clamp 235 is embedded in the inner side of the plate, so that the plate is evenly clamped by the liquid flow holes on the surface of the plate, and the surface of the guide rail 31 is embedded in the surface of the plate, and the top and bottom of the plate are limited. At the same time, the four sides of the plate are restricted by the arc clamp 235 to move smoothly, and the surface of the plate is evenly stressed, thereby effectively avoiding the deflection and dislocation of the plate.

[0050] The third embodiment: Figure 3 , Figure 6 As shown, the inner side of the gate hoist 22 is connected with a stabilizing component 23 through threads, and the stabilizing component 23 is used to clamp the inner side of the plate. The gate hoist 22 controls the stabilizing component 23 to guide the plate to the fixing seat 1;

[0051] The anti-deflection mechanism 2 also includes a liquid pipe 24 and a limit plate 21. The liquid pipe 24 is fixedly mounted on the surface of the stabilizing component 23.

The surface of the fixing seat 1 near the guide component 3 is rotatably connected to a lead roller 26.

[0052] The assembly mechanism 5 includes a mechanism body 51, the surface of which is fixedly mounted on the middle position of the surface of the clamping seat 4, the surface of the mechanism body 51 is fixedly connected to a T-shaped cover plate 52, the surface of the T-shaped cover plate 52 is fixedly connected to a motor 54, the assembly mechanism 5 also includes a limiting circular plate 53, the limiting circular plate 53 is fixedly mounted on the surface of the T-shaped cover plate 52, the middle position of the surface of the mechanism body 51 is fixedly connected to a docking assembly 56, and the position between the mechanism body 51 and the T-shaped cover plate 52 is rotatably connected to a tightening plate assembly 55.

[0053] When in use, the plate heat exchanger is too large to be conveniently compressed and assembled using a press. The device fixes the limit plate 21 on the surface of the fixing seat 1 and fixes the mechanism body 51 on the surface of the compression seat 4. It is easy to disassemble and saves space when in use. After multiple plates are stacked close to the fixing seat 1, the top and bottom of the compression seat 4 slide into the guide assembly 3, and the guide assembly 3 connects the winding wheel 25 with the docking assembly 56. The guide assembly 3 pushes the compression seat 4 close to the overlapped plates. The rotating shaft at the output end of the motor 54 is fixedly connected with a driving gear, which drives the tightening plate assembly 55 to rotate. The tightening plate assembly 55 cooperates with the bolts 6 to push the compression seat 4 close to the plates. The compression of the compression seat 4 and the fixing seat 1 compresses multiple plates to the process thickness. The number of the tightening plate assembly 55 is the same as that of the bolts 6, so that multiple bolts 6 are tightened at the same time, which solves the problem of low assembly efficiency of the heat exchanger caused by manually tightening the bolts multiple times to compress the plates.

[0054] Fourth embodiment: Figure 6 , Figure 7 , Figure 8 As shown, the clamping plate assembly 55 includes a gear body 551, which is arranged at a position between the mechanism body 51 and the T-shaped cover plate 52.

The surface of the docking body 561 is fixedly connected to the middle position of the surface of the mechanism body 51. The inner side surface of the docking body 561 is connected with a threaded block 562 through a thread. The docking assembly 56 also includes an elastic body 564. The surface of the elastic body 564 is fixedly installed on the surface of the threaded block 562. The inner side surface of the threaded block 562 is provided with an internal thread groove 563. The inner side surface of the threaded block 562 is connected with a column 565 through a thread.

[0055] When in use, the surface of the driving gear meshes with the surface of the gear body 551, and the gear bodies 551 mesh with each other. The surface of the clamping nut 554 is embedded in the inner side of the gear body 551, and the mechanism body 51 and the T-shaped cover plate 52 are matched to limit the gear body 551. The limiting groove 552 and the embedded body 553 limit the gear body 551 to the position between the mechanism body 51 and the T-shaped cover plate 52. One side of the clamping nut 554 is in close contact with the surface of the limiting circular plate 53, and the other side of the clamping nut 554 passes through the mechanism body 51 and the clamping The surface of the seat 4 is in close contact. When the gear body 551 rotates, the clamping nut 554 is driven to rotate by the gear body 551. When the steel strand 35 is pulled and wound, the docking body 561 pushes the mechanism body 51 close to the plate. As the clamping nut 554 rotates and moves close to the plate, the clamping nut 554 is screwed into the surface of the bolt 6. The screwing of the clamping nut 554 causes the clamping seat 4 to clamp the plate. Multiple clamping nuts 554 clamp multiple bolts 6 at the same time, avoiding deformation and damage of the plate due to uneven force when the clamping nuts 554 are clamped.

[0056] Fifth embodiment: Figure 5 , Figure 8 As shown, the guide rail 31 is fixedly installed on the surface of the fixed seat 1, and a slide groove 32 is provided on the inner side surface of the guide rail 31. A steel rope 35 is slidably connected to the inner side surface of the guide rail 31. The guide assembly 3 also includes a pulley 33. The surface of the pulley 33 is slidably connected to the inner side surface of the guide rail 31. The surface of the guide rail 31 is fixedly connected to a limiting body 34. The limiting body 34 is used to limit the pulley 33 to prevent it from sliding off. The surface of the docking body 561 is fixedly connected to the middle position of the surface of the mechanism body 51. The inner side surface of the docking body 561 is threadedly connected to a threaded block 562. The docking assembly 56 also includes an elastic body 564. The surface of the elastic body 564 is fixedly installed on the surface of the threaded block 562. An internal thread groove 563 is provided on the inner side surface of the threaded block 562. The inner side surface of the threaded block 562 is threadedly connected to a column 565.

[0057] When in use, one end of the steel strand 35 is fixedly mounted on the surface of the winding wheel 25, and the winding wheel 25 is externally connected to a driving motor to rotate it. The other end of the steel strand 35 is fixed with a column 565. When the device is installed, after the column 565 drives the steel strand 35 to pass through the inner side of the guide rail 31, the column 565 is screwed into the inner side of the threaded block 562, and the surface of the column 565 is matched with the internal thread groove 563. At this time, the restriction of the threaded block 562 makes it impossible for the steel strand 35 to be rewound to the surface of the winding wheel 25 The elastic body 564 prevents the threaded block 562 from hitting the limit body 34. When the plates are overlapped, the clamping seat 4 slides into the inner side of the guide rail 31, pulls the threaded block 562 and screws it into the inner side of the docking body 561, and the winding wheel 25 is driven to rotate, the steel strand 35 shrinks, the lead roller 26 and the pulley 33 support the steel strand 35, and the pulley 33 slides on the inner side of the slide groove 32. The clamping seat 4 is guided and pushed close to the plate so that multiple plates are compressed, thereby making the plates more efficient when being compressed.
