Description

Technical Field

[0001] This utility model relates to the field of support devices, and in particular to a movable plate support device for a multi-flow plate heat exchanger. Background Technology

[0002] Currently, Chinese utility model patent CN217785940U discloses a movable plate support device for a plate heat exchanger, including a fixed base, a support, a fixed block, a first bolt, a first nut, a roller shaft, a bearing, a lead screw, a support block, a second bolt, and a second nut. The fixed base has a support on one side and a square groove on the other side. The outer ends of the fixed base on both sides of the square groove are connected to the fixed block via the first bolt. A roller shaft is located between the fixed block and the support, with bearings at both ends connecting it to the support and the fixed block respectively. Both sides of the square groove have elongated holes on the fixed base, through which the second bolt passes and is locked with the second nut. The side of the fixed base without the square groove is longitudinally connected to the lead screw, which is threaded onto the support block and the first nut. This movable plate support device provides support for the movable plate, and the roller shaft facilitates the movement of the movable plate.

[0003] While existing support devices allow roller shafts to slide quickly on the lower guide rail of the heat exchanger, they still have other problems during use. For example, they lack side guidance, and the bottom of the device only contacts the lower guide rail with the roller shafts. When the device shifts back and forth during sliding, it is very easy for it to fall off the lower guide rail to the ground, resulting in poor stability. Moreover, they cannot fix moving plates of different thicknesses. The types and thicknesses of moving plates are all different. If fixed-size square slots are used to place the moving plates, those that are too large cannot be placed, while those that are too small will have gaps, resulting in low flexibility. To solve the above problems, we propose a movable moving plate support device for multi-flow plate heat exchangers. Utility Model Content

[0004] The purpose of this invention is to provide a movable plate support device for a multi-flow plate heat exchanger, which solves the problems of existing support devices lacking side guiding function and being unable to fix movable plates of different thicknesses.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a movable plate support device for a multi-flow plate heat exchanger, comprising a fixed base, a U-shaped plate symmetrically welded to the bottom of the fixed base, a roller shaft rotatably connected inside the U-shaped plate, two guide plates arranged inside the U-shaped plate, threaded rods rotatably connected to the opposite sides of the two guide plates, threaded grooves opened on both sides of the U-shaped plate, an installation groove opened on the top of the fixed base, a bidirectional screw rotatably connected inside the installation groove, two threaded plates threadedly connected to the surface of the bidirectional screw, and a clamping plate welded to the top of the threaded plates.

[0006] The above technical solution can provide side guidance, preventing the device from slipping off the lower guide rail during sliding and ensuring the stability of the movable plate during sliding. At the same time, it can fix movable plates of different thicknesses, which is not only reliable, but also simple and quick to assemble and disassemble, and has good flexibility.

[0007] The present invention is further configured such that: a limiting rod is welded to one side of each of the two guide plates facing away from each other, and the other end of the limiting rod passes through and extends to the outside of the U-shaped plate.

[0008] By adopting the above technical solution, the guide plate can be limited by the setting of the limiting rod, so as to prevent the guide plate from rotating during the back and forth movement.

[0009] The present invention is further configured such that a first throttle is welded to the other end of the threaded rod.

[0010] By adopting the above technical solution, the setting of the first throttle makes it easy for personnel to rotate the threaded rod.

[0011] The present invention is further configured such that: two slide rails are bolted inside the mounting groove, and sliders that are slidably connected to the slide rails are welded to both sides of the threaded plate.

[0012] By adopting the above technical solution, the threaded plate can be limited by the setting of slide rail and slider, preventing the threaded plate from flipping over when moving back and forth.

[0013] The present invention is further configured such that: the other end of the bidirectional screw extends through to the outside of the fixed base and is welded with a second throttle.

[0014] By adopting the above technical solution and setting the second throttle, it is easy for personnel to rotate the bidirectional screw.

[0015] The present invention is further configured such that both the threaded rod and the bidirectional screw are made of stainless steel.

[0016] Using the above technical solutions, threaded rods and bidirectional screws have the characteristics of high strength, low density and excellent corrosion resistance.

[0017] The present invention is further configured such that rubber pads are installed on the opposite sides of both clamping plates.

[0018] By adopting the above technical solution, the rubber pad can protect the movable plate and prevent the clamping plate from scratching the surface of the movable block when clamping.

[0019] In summary, this utility model has the following beneficial effects:

[0020] 1. This utility model involves first placing the device on the lower guide rail of the heat exchanger, so that the surface of the roller shaft contacts the top of the lower guide rail. After the device is placed stably, the first throttle is held by hand to drive the threaded rod to rotate. When the threaded rod rotates, it will drive the guide plate to fit against the side of the lower guide rail through the cooperation of the bearing and the limit rod. After the guide plate fits against the lower guide rail, the threaded rod is rotated in the opposite direction to allow the roller shaft to slide. This provides a side guiding function, preventing the device from slipping off the lower guide rail during sliding and ensuring the stability of the movable plate during sliding.

[0021] 2. This utility model involves picking up the movable plate and placing it between the two clamping plates on the fixed base. Then, by holding the second throttle, the double-ended screw is rotated. When the double-ended screw rotates, it drives the two threaded plates to move synchronously together through the cooperation of the slide rail and the slider. When the threaded plates move, they drive the clamping plates to clamp the movable plate. This method can fix movable plates of different thicknesses. It is not only secure but also simple and quick to assemble and disassemble, and has good flexibility. Attached Figure Description

[0026] The present invention will be further described in detail below with reference to the accompanying drawings.

[0027] Example 1: Reference Figure 1 and Figure 2A movable plate support device for a multi-flow plate heat exchanger includes a fixed base 1. A U-shaped plate 2 is symmetrically welded to the bottom of the fixed base 1. A roller shaft 3 is rotatably connected inside the U-shaped plate 2. Two guide plates 4 are provided inside the U-shaped plate 2. Threaded rods 5 are rotatably connected to the opposite sides of each guide plate 4. Threaded grooves are provided on both sides of the U-shaped plate 2. The device is first placed on the lower guide rail of the heat exchanger, so that the surface of the roller shaft 3 contacts the top of the lower guide rail. After the device is placed stably, the first handle 11 is held by hand to rotate the threaded rod 5. When the threaded rod 5 rotates, it drives the guide plate 4 to fit against the side of the lower guide rail through the cooperation of the bearing and the limiting rod 10. After the guide plate 4 fits against the lower guide rail, the threaded rod 5 rotates in the opposite direction, allowing the roller shaft 3 to slide. This provides a side guiding function, preventing the device from slipping off the lower guide rail during sliding and ensuring the stability of the movable plate during sliding.

[0028] refer to Figure 1 and Figure 2 Each of the two guide plates 4 has a limiting rod 10 welded to one side facing away from the other. The other end of the limiting rod 10 passes through and extends to the outside of the U-shaped plate 2. By setting the limiting rod 10, the guide plate 4 can be limited to prevent it from rotating during the back-and-forth movement.

[0029] refer to Figure 1 and Figure 2 The other end of the threaded rod 5 is welded with a first throttle 11, which makes it easy for personnel to rotate the threaded rod 5.

[0030] Brief description of the usage process: First, place the device on the lower guide rail of the heat exchanger so that the surface of the roller shaft 3 contacts the top of the lower guide rail. After the device is placed stably, hold the first throttle 11 and rotate the threaded rod 5. When the threaded rod 5 rotates, it will drive the guide plate 4 to fit against the side of the lower guide rail through the cooperation of the bearing and the limit rod 10. After the guide plate 4 fits against the lower guide rail, rotate the threaded rod 5 in the opposite direction so that the roller shaft 3 can slide.

[0031] Example 2: Reference Figure 1 , Figure 2 and Figure 3A movable plate support device for a multi-flow plate heat exchanger is disclosed. A mounting groove 6 is provided on the top of a fixed base 1. A bidirectional screw 7 is rotatably connected inside the mounting groove 6. Two threaded plates 8 are threadedly connected to the surface of the bidirectional screw 7. A clamping plate 9 is welded to the top of the threaded plates 8. By lifting the movable plate and placing it between the two clamping plates 9 on the fixed base 1, and then holding the second throttle 14, the bidirectional screw 7 is rotated. When the bidirectional screw 7 rotates, it drives the two threaded plates 8 to move synchronously together through the cooperation of the slide rail 12 and the slider 13. As the threaded plates 8 move, they drive the clamping plates 9 to clamp the movable plate. This device can fix movable plates of different thicknesses, providing not only a secure fixation but also simple and quick assembly and disassembly, offering good flexibility.

[0032] refer to Figure 3 The mounting groove 6 has two slide rails 12 bolted inside. Both sides of the threaded plate 8 are welded with sliders 13 that are slidably connected to the slide rails 12. The slide rails 12 and sliders 13 can limit the threaded plate 8 and prevent it from flipping when it moves back and forth.

[0033] refer to Figure 1 , Figure 2 and Figure 3 The other end of the bidirectional screw 7 extends through the outside of the fixed base 1 and is welded with a second throttle 14. The second throttle 14 makes it easy for personnel to rotate the bidirectional screw 7.

[0034] refer to Figure 1 , Figure 2 and Figure 3 Both the threaded rod 5 and the double-acting screw 7 are made of stainless steel and have the characteristics of high strength, low density and excellent corrosion resistance.

[0035] refer to Figure 1 Rubber pads 15 are installed on opposite sides of the two clamping plates 9. The rubber pads 15 protect the movable plate and prevent the clamping plates 9 from scratching the surface of the movable block when clamping.

[0036] Brief description of the usage process: By picking up the movable plate and placing it between the two clamping plates 9 on the fixed base 1, then holding the second throttle 14 to drive the bidirectional screw 7 to rotate. When the bidirectional screw 7 rotates, it will drive the two threaded plates 8 to move synchronously through the cooperation of the slide rail 12 and the slider 13. When the threaded plates 8 move, they will drive the clamping plates 9 to clamp the movable plate.
