Description

Technical Field

[0001] This application belongs to the field of heat exchangers, and specifically relates to a device for installing compressor plate fins. Background Technology

[0002] A compressor is a driven fluid machine that raises low-pressure gas to high-pressure gas. A heat exchanger, such as a plate heat exchanger, is usually connected to the side of the compressor to facilitate the exchange of hot and cold media, achieving cooling. A plate heat exchanger is a high-efficiency heat exchanger composed of a series of corrugated metal plates stacked together. Thin rectangular channels are formed between the plates, allowing heat exchange to occur. Plate heat exchangers are ideal for liquid-liquid and liquid-vapor heat exchange. They feature high heat exchange efficiency, low heat loss, compact and lightweight structure, small footprint, easy installation and cleaning, wide application, and long service life.

[0003] Figure 1 A schematic diagram of a plate heat exchanger is shown, including multiple stacked metal plates 2, side plates 3 positioned on both sides of the metal plates, and multiple tension bolts 4 connecting the two side plates and used to tighten the metal plates. The metal plates need to be cleaned periodically to ensure heat exchange efficiency. After cleaning, the metal plates need to be installed between the two side plates and then tightened using the tension bolts. The existing metal plate replacement process includes: before disassembling the metal plates, the distance between the two side plates needs to be measured and the data recorded. Measuring the distance between the two side plates is for subsequent plate installation and to avoid leakage due to inadequate tightening later; the plates are disassembled and cleaned, and after initial installation of the cleaned plates, the tension bolts are tightened while simultaneously measuring the distance between the two side plates. Tightening is stopped once the measured data meets the original data before disassembly, and the installation is complete. In this process, after the metal plates are assembled in sequence, workers use wrenches to tighten the tension bolts to press the plates together, which is time-consuming and increases the labor intensity of maintenance personnel. Utility Model Content

[0004] To address the problems existing in the prior art, this utility model provides a device for installing compressor plate blades, which shortens installation time and reduces labor intensity.

[0005] The technical solution adopted in this utility model is as follows:

[0006] A device for installing plate heat exchanger plates of a compressor is generally a frame structure, including two spaced-apart tension plates and a crossbeam mounted on the top of the two tension plates. The tension plates and the crossbeam are detachably connected. The tension plates can slide along the length of the crossbeam to adjust the distance between the two tension plates. The bottom of the tension plates is provided with multiple hanging plates for supporting the plate heat exchanger. Below the crossbeam is a pressurizing component for pressing the metal plates of the plate heat exchanger.

[0007] Furthermore, the frame structure is U-shaped, with two tightening plates placed vertically to provide support, and a crossbeam forming the connection structure between the two tightening plates. The plate heat exchanger is placed between the two tightening plates below the crossbeam.

[0008] Furthermore, the two tightening plates are arranged one on the left and one on the right. Each tightening plate includes a tightening column and a limiting plate fixed to the top of the tightening column. The tightening column includes a web and two symmetrically fixed flanges on the web. The web has a certain width. The limiting plate overlaps with the web, thereby increasing the connection area between the limiting plate and the web and improving the stability of the connection between the limiting plate and the web. The two limiting plates have corresponding limiting grooves. The limiting grooves are through grooves, for example, in the shape of an I-beam. The tightening column can be, for example, a 12# channel steel.

[0009] Furthermore, the outer surface of the wing plate is equipped with a scale. The scales on the two tightening plates are symmetrically arranged. The scales are arranged from top to bottom along the height direction of the wing plate. The scales are used to measure the thickness of the metal plates of the plate heat exchanger. There is no need to use a tape measure to measure. The data can be read directly through the scale, which is convenient and quick.

[0010] Furthermore, the cross-sectional shape and size of the crossbeam are adapted to the shape and size of the limiting groove, so that the crossbeam passes through the limiting groove of the two limiting plates. The crossbeam can be, for example, an I-beam. The crossbeam is provided with multiple first through holes. Preferably, the multiple first through holes are arranged in a linear array along the length of the crossbeam. The distance between adjacent first through holes can be, for example, 50-100mm. The position of the first through holes is adapted to the length or width of the plate heat exchanger. When the tightening plate moves along the crossbeam to the required position, the positioning bolt passes through the outer side of the tightening plate and is tightened with the matching nut after passing through the first through hole adjacent to the tightening plate to prevent the crossbeam from moving. The crossbeam can be, for example, a 12# I-beam.

[0011] Furthermore, each hanging plate is an L-shaped plate, for example, cut from steel plate, to recycle scraps from the construction site. Each hanging plate is fixed to the bottom of the wing plate of the tightening column. The hanging plate includes a vertical part connected to the wing plate and a horizontal part connected perpendicularly to the vertical part. The hanging plates fixed to the same tightening column are arranged in parallel, and the horizontal part is arranged inside the tightening plate. The horizontal parts of all hanging plates are at the same height and are placed on the ground. The plate heat exchanger is placed on the horizontal part and supports the plate heat exchanger. The horizontal part has a second through hole. The second through hole of the hanging plate connected to the same tightening column is coaxial, and the second through holes of the hanging plates connected to different tightening columns are set at the same height.

[0012] Furthermore, a limiting rod is connected between the second through holes on different sides. The limiting rod includes a support rod passing through the second through hole and a main rod connected between the two support rods. The main rod is preferably telescopic and includes a sleeve and a telescopic rod that moves along the inner wall of the sleeve. The sleeve has a threaded hole on its wall, and a bolt is threaded into the threaded hole. When the telescopic rod is adjusted to a suitable length, the bolt is tightened to abut against the telescopic rod to prevent it from sliding. The limiting rod is used to prevent the tightening plate from spreading outward.

[0013] Furthermore, the pressurizing component is either a manually operated jack or an automatic hydraulic pressurizer. The jack is placed on the top side plate of the plate heat exchanger, with its tip pressing against the crossbeam. Manually pressing the jack handle compresses the metal plates. The automatic hydraulic pressurizer is fixed below the crossbeam and electrically connected to the start button. The automatic hydraulic pressurizer includes a cylinder and a piston rod that extends and retracts along the cylinder. The piston rod is positioned directly below the midpoint of the two tightening plates. When the start button is pressed, the piston rod extends and compresses the top side plate of the plate heat exchanger. When the metal plates are compressed to the specified thickness, the start button is turned off, stopping the compression. By using a pressurizing component to compress the metal plates, the labor intensity of workers is reduced, work efficiency is improved, and the installation time of the metal plates is shortened.

[0014] The beneficial effects of this utility model are:

[0015] This utility model discloses a device for installing compressor plate heat exchangers. The overall structure is a U-shaped frame, including tightening plates and a crossbeam supported at the top of two tightening plates. The plate heat exchanger is placed between the two tightening plates below the crossbeam and supported by a hanging plate. A pressurizing component is provided between the plate heat exchanger and the crossbeam. The pressurizing component applies pressure, compressing the metal plates. The thickness of the metal plates can be manually fine-tuned by tightening bolts. Using the pressurizing component to compress the metal plates reduces the labor intensity of workers, improves work efficiency, and shortens the installation time of the metal plates. A scale is provided on the tightening plates for direct data reading, which is convenient and quick. A limiting rod inserted into the second through hole prevents the tightening plates from spreading outwards. This utility model's device for installing compressor plate heat exchangers has a simple structure, saves time, and enables convenient installation of metal plates. The crossbeam and tightening plates, and the limiting rod and tightening plates are detachable for easy storage. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0027] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0028] like Figure 2-6 As shown, a device for installing a compressor plate heat exchanger has an overall frame structure, including two spaced-apart tension plates 5 and a crossbeam 6 mounted on the top of the two tension plates 5. The tension plates 5 and the crossbeam 6 are detachably connected. The tension plates 5 can slide along the length of the crossbeam 6 to adjust the distance between the two tension plates 5. The bottom end of the tension plates 5 is provided with multiple hanging plates 7 for supporting the plate heat exchanger 1. Below the crossbeam 6 is a pressurizing component 8 for pressing the metal plates 2 of the plate heat exchanger 1.

[0029] like Figure 2 , Figure 6 As shown, the frame structure is U-shaped, with two tightening plates 5 placed vertically to provide support, and a crossbeam 6 forming the connection structure between the two tightening plates 5. The plate heat exchanger 1 is placed between the two tightening plates 5 below the crossbeam 6.

[0030] like Figure 2 , Figure 3 As shown, the two tightening plates 5 are arranged on the left and right. The tightening plate 5 includes a tightening column 501 and a limiting plate 502 fixed to the top of the tightening column 501. The tightening column 501 includes a web plate 5011 and two wing plates 5012 symmetrically fixed on the web plate 5011. The web plate 5011 has a certain width. The limiting plate 502 partially overlaps with the web plate 5011, thereby increasing the connection area between the limiting plate 502 and the web plate 5011 and improving the stability of the connection between the limiting plate 502 and the web plate 5011. The two limiting plates 502 have corresponding limiting grooves 503. The limiting grooves 503 are through grooves, and the limiting grooves 503 are, for example, I-shaped. The tightening column 501 can be, for example, a No. 12 channel steel.

[0031] like Figure 2 , Figure 3 As shown, a scale 9 is provided on the outer surface of the wing plate 5012. The scales 9 on the two tightening plates 5 are symmetrically arranged, and the scales 9 are arranged from top to bottom along the height direction of the wing plate 5012. The scales 9 are used to measure the thickness of the metal plates 2 of the plate heat exchanger 1. There is no need to use an additional tape measure. The data can be read directly through the scales 9, which is convenient and quick. Moreover, the symmetrically arranged scales 9 allow direct observation of whether the metal plates 2 of the plate heat exchanger 1 are horizontally aligned. This improves the sealing performance of the metal plates 2 of the plate heat exchanger 1 during installation, prevents potential sealing problems caused by misalignment of the metal plates 2 due to not being placed horizontally, improves the reliability of installation, and ensures installation efficiency.

[0032] like Figure 2 , Figure 4As shown, the cross-sectional shape and size of the crossbeam 6 are adapted to the shape and size of the limiting groove 503, so that the crossbeam 6 passes through the limiting groove 503 of the two limiting plates 502. The crossbeam 6 can be, for example, an I-beam. The crossbeam 6 is provided with multiple first through holes 10. Preferably, the multiple first through holes 10 are arranged in a linear array along the length direction of the crossbeam 6. The distance between adjacent first through holes 10 can be, for example, 50-100mm. The position of the first through holes 10 is adapted to the length or width of the plate heat exchanger 1. When the tightening plate 5 moves along the crossbeam 6 to the required position, the positioning bolt 11 passes through the outer side of the tightening plate 5 and is adjacent to the first through hole 10, and is then tightened with a matching nut to prevent the crossbeam 6 from moving. The crossbeam 6 can be, for example, a 12# I-beam.

[0033] like Figure 2 , Figure 3 As shown, each hanging plate 7 is an L-shaped plate, for example, made by cutting steel plates to recycle scraps from the construction site. Each hanging plate 7 is fixed to the bottom end of the wing plate 5012 of the tightening column 501. The hanging plate 7 includes a vertical part 701 connected to the wing plate 5012 and a horizontal part 702 connected to the vertical part 701 perpendicularly. The hanging plates 7 fixed to the same tightening column 501 are arranged in parallel and the horizontal part 702 is arranged inside the tightening plate 5. The horizontal parts 702 of all hanging plates 7 are at the same height and are placed on the ground. The plate heat exchanger 1 is placed on the horizontal part 702 and supports the plate heat exchanger 1. The horizontal part 702 has a second through hole 703. The second through hole 703 of the hanging plate 7 connected to the same tightening column 501 is coaxial and the second through hole 703 of the hanging plate 7 connected to different tightening columns 501 are at the same height.

[0034] Figure 2 , Figure 5 As shown, a limiting rod 12 is connected between the second through holes 703 on different sides. The limiting rod 12 includes a support rod 1201 that passes through the second through hole 703 and a main rod 1202 connected between the two support rods 1201. The main rod 1202 is preferably telescopic. The main rod 1202 includes a sleeve and a telescopic rod that moves along the inner wall of the sleeve. A threaded hole is opened on the sleeve wall, and a bolt is connected to the threaded hole. When the telescopic rod is adjusted to a suitable length, the bolt is tightened to abut against the telescopic rod to prevent the telescopic rod from sliding. The limiting rod 12 is used to prevent the tightening piece 5 from spreading outward.

[0035] like Figure 2 , Figure 6As shown, the pressurizing component 8 is either a manually operated jack or an automatic hydraulic pressurizer. The jack is placed on the top side plate 3 of the plate heat exchanger 1, with its top end pressing against the crossbeam 6. Manually pressing the jack handle compresses the metal plate 2. The automatic hydraulic pressurizer is fixed below the crossbeam 6 and is electrically connected to the start button. The automatic hydraulic pressurizer includes a cylinder 801 and a piston rod 802 that extends and retracts along the cylinder 801. The piston rod 802 is positioned directly below the midpoint of the two tightening plates 5. When the start button is turned on, the piston rod 802 extends and compresses the top side plate 3 of the plate heat exchanger 1. When the metal plate 2 is compressed to the specified thickness, the start button is turned off, stopping the compression. By using the pressurizing component 8 to compress the metal plate 2, the labor intensity of workers is reduced, work efficiency is improved, and the installation time of the metal plate 2 is shortened. Example

[0036] A method of using a device for mounting compressor plate fin changers includes:

[0037] (1) First, the metal plates 2 of the plate heat exchanger 1 are initially installed (each metal plate 2 has a groove, and they are stacked in opposite directions and locked together. When compressed, they will be locked tighter and tighter). The distance between the two tightening pieces 5 is preset according to the length of the plate heat exchanger 1 and the two tightening pieces 5 are positioned. The plate heat exchanger 1 that has been initially installed is placed on the horizontal part 702. The side plate 3 of the plate heat exchanger 1 located below is placed on the horizontal part 702. The hanging plate 7 hooks the plate heat exchanger 1. The plate heat exchanger 1 is suspended. The two tightening pieces 5 are brought together until the two tightening pieces 5 are against the edge of the side plate 3 of the plate heat exchanger 1.

[0038] (2) Adjust the length of the main rod 1202 so that the support rod 1201 can be inserted into the second through hole 703. After the length of the main rod 1202 is determined, tighten the bolt to hold the telescopic rod and fix the length of the main rod 1202. Then insert the support rod 1201 into the second through hole 703 to prevent the two tightening pieces 5 from spreading outward.

[0039] (3) The crossbeam 6 passes through the two limiting grooves 503. Adjust the position of the crossbeam 6. The positioning bolt 11 passes through the outer side of the tightening plate 5 and the first through hole 10 adjacent to the tightening plate 5. Then tighten it with the matching nut. Since the crossbeam 6 on the outer side of the two tightening plates 5 is equipped with positioning bolts 11, it can prevent the crossbeam 6 from moving. The pressure component 8 applies pressure to squeeze the metal plate 2. When the metal plate 2 is compressed to the specified thickness and the readings of the scale 9 on the two tightening plates 5 at both ends of the metal plate 2 are consistent, stop the compression. Finally, tighten the tension bolt 4 and manually fine-tune it. The compression is completed.

[0040] (4) Loosen the nut of the positioning bolt 11, remove the positioning bolt 11, and at the same time pull out the limit rod 12 from the second through hole 703, separate the tightening plate 5 outward, and take out the compressed plate heat exchanger 1.

[0041] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the scope of protection of the present invention. Therefore, the scope of protection of this patent should be determined by the appended claims.
