Description

Technical Field

[0001] This utility model relates to the field of heat exchange equipment, specifically a novel plate heat exchanger. Background Technology

[0002] Plate heat exchangers are high-efficiency heat exchangers composed of multiple 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, featuring high heat exchange efficiency, low heat loss, compact and lightweight structure, small footprint, wide application, and long service life. In contrast, while some heat exchange plates in a detachable heat exchanger may only require replacement, disassembly still necessitates removing the entire set of plates. This can lead to displacement between the plates, causing leaks, wasting installation time, and increasing the risk of damage to the plates during the replacement process.

[0003] To address the aforementioned issues, the prior patent CN209945090U describes a detachable plate heat exchanger, including a frame with rails at both ends. The frame has fixed and movable end plates, and a heat exchange plate assembly is positioned between them. The fixed and movable end plates are connected by connecting rods on both sides of the heat exchange plate assembly. These connecting rods include a front connecting rod and a rear connecting rod, which are threaded together. In this device, only the heat exchange plate to be replaced needs to be removed and reinstalled; other heat exchange plates that do not require replacement can remain in the heat exchanger. Disassembly and installation are convenient and quick, and the heat exchange plates are less likely to be damaged during disassembly. However, when disassembling and assembling the heat exchange plate assembly, the front and rear connecting rods need to be separated. Since there are many connecting rods, multiple rods need to be disassembled during the disassembly process, making disassembly inconvenient. Utility Model Content

[0004] The purpose of this utility model is to provide a plate heat exchanger that solves the problem that in the existing plate heat exchanger, disassembly is not convenient because there are many connecting rods and multiple connecting rods need to be disassembled.

[0005] The technical solution of this utility model:

[0006] A plate heat exchanger includes a fixed plate, a movable plate, and a gantry. A heat exchange plate assembly is installed between the fixed plate and the movable plate. An adjustable clamping device is provided between the fixed plate and the movable plate on both sides of the heat exchange plate assembly. The adjustable clamping device includes two clamping devices and an adjustment mechanism between the two clamping devices.

[0007] The clamping device includes a clamping plate, a rotating screw, a washer nut, and a rubber ring. The clamping plate has two socket holes in the middle and a locking hole between the two socket holes. Two rotating screws with external threads are fixedly welded to the side of the clamping plate facing the heat exchange plate. The rotating screws pass through the snap-fit ​​groove on the side of the fixed plate or movable plate. A washer nut is installed on the end of the rotating screw that passes through the snap-fit ​​groove. The outer shape of the washer nut is larger than the snap-fit ​​groove. A rubber ring is provided between the rotating screw and the snap-fit ​​groove.

[0008] The adjusting device includes a fixed sleeve plate and a movable sleeve plate, both of which are L-shaped. One end of the movable sleeve plate is inserted into the fixed sleeve plate. The inner sides of the other ends of both the movable and fixed sleeve plates are provided with two upper and lower locking bolts. A fixed sleeve is fixedly installed between the two locking bolts of the fixed sleeve plate. A rotating bolt is installed between the two locking bolts of the movable sleeve plate. The rotating bolt passes through the movable plate and is threadedly connected to the fixed sleeve. Two sliding grooves are opened on the inner side of the end of the fixed and movable sleeve plates where they are inserted. A limit block is installed on the movable sleeve plate at the position corresponding to the sliding groove. The limit block slides back and forth in the sliding groove.

[0009] The two snap-fit ​​bolts on the fixed sleeve are inserted into the socket holes on the clamping plate of a clamping device, the fixed sleeve is inserted into the locking hole on the clamping plate, the two snap-fit ​​bolts on the movable sleeve are inserted into the socket holes on the clamping plate of another clamping device, and the rotating bolt is inserted into the locking hole on the clamping plate.

[0010] The beneficial effects of this utility model are:

[0011] 1. During the disassembly and assembly of the plate heat exchanger of this application, the two clamping plates on both sides of the heat exchange plate assembly are separated by rotating the rotating bolts, and the movable plate is slid to the side along the guide rod, thereby removing and replacing the heat exchange plates. During assembly, the adjusting device is installed on both sides of the clamping plate, and the movable plate and the fixed plate are pulled by the washer nut to fix the internal heat exchange plate assembly. In this way, one side can be completely disassembled and assembled in one go, saving manpower and time and improving the disassembly and assembly efficiency of the device.

[0012] 2. The limiting grooves of the heat exchange plates of the plate heat exchanger of this application are attached to the side of the rotating screw of the clamping device, and the upper and lower ends are clamped inside the guide rod to limit the heat exchange plates. At the same time, the magnetic blocks at the corners of multiple heat exchange plates make multiple heat exchange plates stick together, avoiding the problem of multiple heat exchange plates slipping when the operator picks up one heat exchange plate, which facilitates installation and provides convenience for disassembly and assembly.

Detailed Implementation

[0021] To address the problems in the background art, this application presents a novel plate heat exchanger, which adds clamping and adjusting devices to both sides of the heat exchange plate assembly. When it is necessary to replace the heat exchange plates, it is not necessary to remove all the rotating screws to achieve the disassembly and assembly of each heat exchange plate.

[0022] To make the technical problems, technical solutions and advantages of this application clearer, a detailed description will be provided below in conjunction with the accompanying drawings and specific embodiments.

[0023] As attached Figure 1-2As shown, this application discloses a plate heat exchanger, including a fixed plate 1, a movable plate 2, and a gantry 3. A heat exchange plate assembly 4 is detachably installed between the fixed plate 1 and the movable plate 2. A crossbeam 5 and a guide rod 6 are installed between the fixed plate 1, the movable plate 2, and the gantry 3. One guide rod 6 is installed at each of the upper and lower ends. The crossbeam 5 and the guide rod 6 are fixedly connected to the fixed plate and the gantry 3. The movable plate 2 can slide back and forth on the guide rod and the crossbeam. The upper and lower ends of both sides of the fixed plate 1 and the movable plate 2 are provided with locking grooves 7. An adjustable clamping device is provided between the fixed plate 1 and the movable plate 2 on both sides of the heat exchange plate assembly 4. The adjustable clamping device includes two clamping devices 8 and an adjustment device 9 between the two clamping devices 8.

[0024] As attached Figure 1 , 3 As shown, the clamping device 8 includes a clamping plate 81, a rotating screw 82, a washer nut 83, and a rubber ring 84. The clamping plate 81 has two socket holes 85 in its center, and a locking hole 86 between the two socket holes 85. Two externally threaded rotating screws 82 are fixedly welded to the side of the clamping plate 81 facing the heat exchange plate. The rotating screws 82 pass through a locking groove 7 on the side of the fixed plate 1 or the movable plate 2. A washer nut 83 is installed on the end of the rotating screw 82 that extends out of the locking groove 7. The washer nut 83 is larger than the locking groove 7. A rubber ring 84 is provided between the rotating screw 82 and the locking groove 7. The rubber ring secures the rotating screw inside the locking groove, preventing it from wobbling inside the groove. In use, the clamping grooves of the fixed plate and the movable plate are respectively clamped by the washer nut. At the same time, the distance between the two clamping plates is adjusted by the rotation of the washer nut on the rotating screw, that is, the distance between the heat exchange plates. This allows the clamping device to adapt to heat exchange plate groups of different thicknesses, thus improving the applicability of the device.

[0025] As attached Figure 1 , 4As shown, the adjusting device 9 includes a fixed sleeve 91 and a movable sleeve 92. Both the fixed sleeve 91 and the movable sleeve 92 are L-shaped structures. One end of the movable sleeve 92 is inserted into the fixed sleeve 91 (the end where the fixed sleeve and the movable sleeve are inserted is a flat groove structure, and the movable sleeve is inserted into the flat groove). The inner side of the other end of the movable sleeve 92 and the fixed sleeve 91 is provided with two upper and lower locking bolts 93. A fixed sleeve 94 is fixedly installed between the two locking bolts 93 of the fixed sleeve 91. A rotating bolt 95 is installed between the two locking bolts 93 of the movable sleeve 92. The rotating bolt 95 passes through the movable sleeve 92 and is threadedly connected to the fixed sleeve 94. Two upper and lower sliding grooves 96 are opened on the inner side of the part where the fixed sleeve 91 and the movable sleeve 92 are fitted together. A limit block 97 is installed on the movable sleeve 92 at the position corresponding to the sliding groove 96. The limit block 97 slides back and forth in the sliding groove 96. The sliding groove limits the movement of the limiting block, allowing the movable sleeve to move inside the fixed sleeve, thus preventing the fixed sleeve 91 from separating from the movable sleeve 92.

[0026] The two snap-fit ​​bolts 93 on the fixed sleeve 91 are inserted into the socket holes 85 on the clamping plate 81 of the first clamping device, and the fixed sleeve 94 is inserted into the locking hole 86 on the first clamping plate 81. The two snap-fit ​​bolts 93 on the movable sleeve 92 are inserted into the socket holes 85 on the clamping plate 81 of the second clamping device, and the rotating bolt 95 is inserted into the locking hole 86 on the second clamping plate 81.

[0027] As attached Figure 5 As shown, the heat exchange plate assembly 4 includes several heat exchange plates 41. Magnet blocks 42 are fixedly installed at each of the four corners of each heat exchange plate 41. Limiting grooves 43 corresponding to the rotating screw are provided at the upper and lower ends of both sides of each heat exchange plate 41. The rotating screw 82 of the clamping device is embedded in the limiting grooves 43. The magnet blocks ensure that the multiple heat exchange plates automatically adhere to each other, preventing them from scattering during replacement and thus avoiding difficulties in assembly and installation.

[0028] The working process of the plate heat exchanger in this application is as follows:

[0029] During the disassembly and assembly of the plate heat exchanger, the fixed sleeve is separated from the rotating bolt by rotating the rotating bolt. The locking plates on the fixed and movable sleeves are then removed from the socket holes on the two clamping plates, thus separating the two clamping plates. The movable plate is then slid away from the fixed plate along the guide rod, allowing the heat exchange plates that need to be replaced to be removed and replaced. Similarly, by installing the adjusting device on both sides of the two clamping plates using the same method, the rotating bolt is tightened into the fixed sleeve using a wrench. The clamping plates on both sides, through the use of washer nuts, pull the movable and fixed plates to clamp and fix the internal heat exchange plate assembly. During installation, the screw can be secured to the locking grooves of the fixed plate and the movable plate using rubber rings. When the heat exchange plates are installed between the fixed plate and the movable plate, the limiting grooves of the heat exchange plates are made to fit against the side of the rotating screw. At the same time, the upper and lower ends are secured to the guide rod to limit the position of the heat exchange plates. Meanwhile, the magnetic blocks at the corners of multiple heat exchange plates are used to keep the multiple heat exchange plates in contact with each other, preventing multiple heat exchange plates from slipping when the operator removes another heat exchange plate.

[0030] Finally, the following points should be noted: First, in the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection", and "linkage" should be interpreted broadly, and can be mechanical or electrical connections, or internal connections between two components, or direct connections.
