Description

Technical Field

[0001] This utility model relates to the field of plate heat exchanger technology, and in particular to a detachable high heat transfer plate heat exchanger. Background Technology

[0002] A heat exchanger is a device that transfers part of the heat from a hot fluid to a cold fluid; it is also called a heat exchanger. Heat exchangers play an important role in chemical, petroleum, power, food, and many other industrial production processes. In chemical production, heat exchangers can be used as heaters, coolers, condensers, evaporators, and reboilers, and are widely applied. Plate heat exchangers are a new type of high-efficiency heat exchanger composed of a series of metal plates with a certain corrugated shape stacked together. Thin rectangular channels are formed between the plates, through which heat exchange occurs. They feature high heat exchange efficiency, low heat loss, compact and lightweight structure, small footprint, convenient installation and cleaning, wide application, and long service life.

[0003] Existing detachable high-heat-transfer plate heat exchangers still have the following problems:

[0004] Some detachable high-heat-transfer plate heat exchangers have a detachable structure, but some detachable plate heat exchangers are not designed reasonably, resulting in complicated installation and disassembly processes that require many tools and consume a lot of time and manpower. In addition, some detachable plate heat exchangers are not fastened properly, which leads to increased gaps between plates, causing liquid-vapor leakage, reducing heat exchange efficiency, reducing structural stability, accelerating component wear, shortening equipment lifespan, and may also cause abnormal vibration and noise due to loosening, and even cause safety hazards. Utility Model Content

[0005] The purpose of this utility model is to provide a detachable high heat transfer plate heat exchanger, which solves the problems of some existing detachable high heat transfer plate heat exchangers having unreasonable structural design, resulting in complicated installation and disassembly processes that require many tools and consume a lot of time and manpower. In addition, some detachable plate heat exchangers are not properly fastened, which leads to increased gaps between plates, causing liquid-vapor leakage, reducing heat exchange efficiency, reducing structural stability, aggravating component wear, shortening equipment lifespan, and may also cause abnormal vibration and noise due to loosening, and even cause safety hazards.

[0006] To achieve the above objectives, a detachable high heat transfer plate heat exchanger is provided, comprising a base, a fixing plate 1 fixedly mounted on the left end of the base, a slot in the middle of the base, limit posts fixedly mounted at both ends of the slot, a lead screw rotatably mounted in the middle of the slot, one end of the lead screw passing through the base and connected to a servo motor via a coupling, the servo motor being fixedly mounted on one side of the base, a fixing plate 2 fitted onto the lead screw, the fixing plate 2 being slidably mounted on the limit posts, a plurality of plate heat exchangers 1 tightly fitted between the fixing plate 1 and the fixing plate 2, and connecting pipes fixedly mounted on one side of each fixing plate 2.

[0008] Both ends of the base are fixed with slide rails 2. The bottom ends of the fixing plate 1, plate heat exchanger 1 and fixing plate 2 are all provided with slide grooves 1, which are adapted to slide rails 2.

[0009] Several threaded holes are provided at both ends of the first fixed plate, the first plate heat exchanger, and the second fixed plate. Fastening bolts are installed in the threaded holes, and nuts are installed at the ends of the fastening bolts.

[0014] 1. The design of this patent is simple and reasonable, easy to install and disassemble, requires few tools, and reduces installation time and manpower;

[0015] 2.

Detailed Implementation

[0022] Reference Figure 1-4 This utility model discloses a detachable high-heat-transfer plate heat exchanger, comprising a base 1, a fixing plate 3 fixedly mounted on the left end of the base 1, a slot 16 formed in the middle of the base 1, limit posts 14 fixedly mounted at both ends of the slot 16, a lead screw 15 rotatably mounted in the middle of the slot 16, one end of the lead screw 15 passing through the base 1 and connected to a servo motor 2 via a coupling, the servo motor 2 being fixedly mounted on one side of the base 1, a second fixing plate 5 fitted onto the lead screw 15, the second fixing plate 5 being slidably mounted on the limit posts 14, a plurality of plate heat exchangers 12 tightly fitted between the first fixing plate 3 and the second fixing plate 5, and one side of the second fixing plate 5... All are fixedly installed with connecting pipes 11. In use, first loosen bolt 9 to remove the limit block 10. Then, start the servo motor 2 to drive the lead screw 15 connected to the output end of the servo motor 2 through the coupling to rotate. This will cause the fixing plate 2 5, which is installed on the lead screw 15 and slidably installed on the limit post 14, to move forward, thereby disassembling the fixing plate 2 5. Then, slide the plate heat exchanger 12 on the base 1 through the slide rail 1 4 and the slide rail 2 13. After installation, install the fixing plate 2 5 on the lead screw 15. Start the servo motor 2 again to drive the fixing plate 2 5 to move back, thereby fixing the plate heat exchanger 12.

[0023] A slide rail 4 is fixedly installed at the upper center of one side of the fixed plate 3. A slide groove 18 is provided at the upper center of the fixed plate 3, the plate heat exchanger 12, and the fixed plate 5, and the slide groove 18 is adapted to the slide rail 4. Slide rails 13 are fixed at both ends of the base 1. Slide grooves 17 are provided at both ends of the bottom of the fixed plate 3, the plate heat exchanger 12, and the fixed plate 5, and the slide grooves 17 are adapted to the slide rails 13. Several threaded holes 8 are provided at both ends of the fixed plate 3, the plate heat exchanger 12, and the fixed plate 5. Fastening bolts 7 are installed in the threaded holes 8, and nuts 6 are installed at the ends of the fastening bolts 7. During use, the nuts 6 are tightened to secure the bolts. The fastening bolts 7 and nuts 6 can be used to perform secondary fixing of the fixing plate 3, the fixing plate 5 and the plate heat exchanger 12. Through double fastening, the gaps between the plates are prevented from increasing, which could lead to liquid-vapor leakage, thus improving heat exchange efficiency. At the same time, the structural stability is improved, component wear is reduced, and the service life of the equipment is extended. The base 1 is threaded with a limit block 10 on one side of the slot 16. Bolts 9 are threaded on both the base 1 and the limit block 10. A limit hole 19 is opened in the middle of one side of the limit block 10, and limit holes 20 are opened at both ends of one side of the limit block 10. The limit hole 19 is adapted to the lead screw 15, and the limit hole 20 is adapted to the limit post 14.

[0024] When using a detachable high heat transfer plate heat exchanger, first loosen bolt 9 to remove the limiting block 10. Then, start the servo motor 2 to drive the lead screw 15 connected to the output end of the servo motor 2 via the coupling to rotate, thereby moving the fixing plate 2 5, which is fitted on the lead screw 15 and slidably mounted on the limiting post 14, forward, thus disassembling the fixing plate 2 5. Then, slide the plate heat exchanger 12 onto the base 1 via slide rail 1 4 and slide rail 2 13. After installation, fit the fixing plate 2 5 onto the lead screw 15. Start the servo motor 2 again to drive the fixing plate 2 5 back, thereby fixing the plate heat exchanger 12. Finally, by loosening the fastening bolt 7 and nut 6, a second fixing of the fixing plate 3, fixing plate 2 5, and plate heat exchanger 12 can be initiated.
