Description

Technical Field

[0001] This utility model relates to the technical field of spiral plate heat exchangers, specifically a combined spiral plate heat exchanger. Background Technology

[0002] A spiral plate heat exchanger is a high-efficiency heat exchange device that uses spiral plates as heat transfer elements. It is mainly made of two parallel metal plates rolled together to form two uniform spiral channels, and heat exchange between two media is achieved through the plate walls.

[0003] Traditional spiral plate heat exchangers mostly use a fixed support structure, lack height adjustment function, and are difficult to adapt to unevenness errors in complex installation environments. When encountering uneven ground, external pads are needed to adjust it, resulting in low flexibility during installation. Utility Model Content

[0004] The purpose of this utility model is to provide a combined spiral plate heat exchanger that solves the problem that traditional spiral plate heat exchangers mostly adopt a fixed support structure, lack height adjustment function, are difficult to adapt to unevenness errors in complex installation environments, and require external pads for adjustment when encountering uneven ground.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to a combined spiral plate heat exchanger, including a spiral plate heat exchanger body. Two sets of support mechanisms are fixedly installed on the lower surface of the spiral plate heat exchanger body. The support ends of the support mechanisms are all located below the spiral plate heat exchanger body, and each support end of the support mechanism is equipped with a buffer pad.

[0007] Furthermore, the support mechanism includes a support plate, which is fixedly installed on the lower surface of the spiral plate heat exchanger body. The support plate has an internal cavity, and sliding grooves are provided on both sides of the support plate. A lead screw is rotatably connected inside the cavity, and a worm gear is fixedly installed on the peripheral side of the lead screw.

[0008] Furthermore, a movable plate is threadedly connected to the outer surface of the lead screw, and connecting rods are fixedly installed on both sides of the movable plate. A limiting plate is fixedly installed at one end of each connecting rod. The limiting plates are slidably connected inside the slide groove, and the limiting plates extend to the outer surface of the support plate through the slide groove.

[0009] Furthermore, a support rod is fixedly installed on the lower surface of each limiting plate, and a balance plate is fixedly installed on one end of each support rod.

[0010] Furthermore, a rotating rod is rotatably connected inside the support plate. A worm gear is fixedly installed at one end of the rotating rod, and the worm gear is meshed with a worm wheel. A throttle handle is fixedly installed at the other end of the rotating rod, and the worm wheel is meshed with the worm gear.

[0011] Furthermore, buffer pads are fixedly installed on the lower surfaces of both the balance plate and the support plate.

[0012] This utility model has the following beneficial effects:

[0013] (1) When the spiral plate heat exchanger body is placed on an uneven ground, the operator can rotate the handle on the corresponding support mechanism. The handle drives the rotating rod fixed thereto to rotate synchronously. Since the worm and worm wheel are meshed, the rotational motion is transmitted to the worm wheel and drives it to rotate, which in turn causes the lead screw fixed on the same axis to rotate. The thread of the lead screw is engaged with the moving plate. Since the two sides of the moving plate are fixed with limit plates through connecting rods, and the limit plates slide in the groove of the support plate, the rotation of the lead screw will drive the moving plate to move the limit plates along the groove. The displacement of the limit plates will further push the support rod below to extend and retract, and finally realize the height adjustment of the balance plate, thereby adapting to the unevenness error of complex installation surfaces and improving practicality.

[0014] (2) In the two sets of symmetrically arranged support mechanisms of this utility model, all balance plates and the bottom of the original support plates are equipped with buffer pads, which can effectively absorb the vibration and impact loads during equipment operation, ensure the overall stability, and achieve the effect of greatly reducing the resonance risk caused by fluid pulsation.

[0015] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1-4 As shown, this utility model is a combined spiral plate heat exchanger, including a spiral plate heat exchanger body 1. Two sets of support mechanisms 2 are fixedly installed on the lower surface of the spiral plate heat exchanger body 1. The support ends of the support mechanisms 2 are all located below the spiral plate heat exchanger body 1, and buffer pads 3 are installed on the support ends of the support mechanisms 2.

[0025] When the spiral plate heat exchanger body 1 is placed on an uneven ground, the operator rotates the handle 213 on the corresponding support mechanism 2. The handle 213 drives the rotating rod 211 fixed thereto to rotate synchronously. Since the worm 212 is meshed with the worm wheel 205, the rotational motion is transmitted to the worm wheel 205 and drives it to rotate, which in turn causes the coaxially fixed lead screw 204 to rotate. The thread of the lead screw 204 is engaged with the moving plate 206. Since the moving plate 206 is fixed with limit plates 208 on both sides by connecting rods 207, and the limit plates 208 slide in the groove 203 of the support plate 201, the rotation of the lead screw 204 will drive the moving plate 206 to move the limit plates 208 along the groove 203. The displacement of the limit plates 208 further pushes the support rod 209 below to extend and retract, ultimately realizing the height adjustment of the balance plate 210, thereby adapting to the unevenness error of complex installation surfaces and improving practicality.

[0026] The support mechanism 2 includes a support plate 201, which is fixedly installed on the lower surface of the spiral plate heat exchanger body 1. The support plate 201 has a receiving cavity 202 inside, and sliding grooves 203 are provided on both sides of the support plate 201. A lead screw 204 is rotatably connected inside the receiving cavity 202, and a worm gear 205 is fixedly installed on the circumferential side of the lead screw 204.

[0027] The outer surface of the lead screw 204 is threaded with a movable plate 206. Connecting rods 207 are fixedly installed on both sides of the movable plate 206. Limiting plates 208 are fixedly installed at one end of each connecting rod 207. The limiting plates 208 are slidably connected inside the slide groove 203. The limiting plates 208 extend to the outer surface of the support plate 201 through the slide groove 203.

[0028] Support rods 209 are fixedly installed on the lower surface of the limiting plate 208, and a balance plate 210 is fixedly installed on one end of each support rod 209.

[0029] The support plate 201 is rotatably connected to a rotating rod 211. A worm 212 is fixedly installed at one end of the rotating rod 211. The worm 212 and the worm wheel 205 are meshed and connected. A throttle 213 is fixedly installed at the other end of the rotating rod 211. The worm wheel 205 and the worm 212 are meshed and connected.

[0030] A buffer pad 3 is fixedly installed on the lower surface of both the balance plate 210 and the support plate 201;

[0031] In the two sets of symmetrically arranged support mechanisms 2, all balance plates 210 and the bottom of the original support plate 201 are equipped with buffer pads 3, which can effectively absorb the vibration and impact loads during equipment operation, ensure the overall stability, and significantly reduce the risk of resonance caused by fluid pulsation.

[0032] When in use, when the spiral plate heat exchanger body 1 is placed on an uneven ground, the operator can rotate the handle 213 on the corresponding support mechanism 2. The handle 213 drives the rotating rod 211 fixed thereto to rotate synchronously. Since the worm 212 is meshed with the worm wheel 205, the rotational motion is transmitted to the worm wheel 205 and drives it to rotate, which in turn causes the coaxially fixed lead screw 204 to rotate. The thread of the lead screw 204 is engaged with the moving plate 206. Since the moving plate 206 is fixed with the limit plate 208 on both sides by the connecting rod 207, and the limit plate 208 slides in the groove 203 of the support plate 201, the rotation of the lead screw 204 will drive the moving plate 206 to drive the limit plate 208 to move along the groove 203. The displacement of the limit plate 208 further pushes the support rod 209 below to extend and retract, and finally realizes the height adjustment of the balance plate 210, thereby adapting to the unevenness error of the complex installation surface and improving practicality.

[0033] In the two sets of symmetrically arranged support mechanisms 2, all balance plates 210 and the bottom of the original support plate 201 are equipped with buffer pads 3, which can effectively absorb the vibration and impact loads during equipment operation, ensure the overall stability, and significantly reduce the risk of resonance caused by fluid pulsation.
