Description

Technical Field

[0001] This utility model relates to the field of pharmaceutical technology, and in particular to a heat exchanger for pharmaceutical equipment. Background Technology

[0002] A heat exchanger is a device used for heat exchange and is widely used in various industrial fields, including pharmaceuticals, chemicals, food processing, and energy. It is mainly used to heat, cool, and maintain the temperature of reactants. By regulating the temperature of the fluid, it ensures that the chemical reaction takes place within the optimal temperature range, improves reaction efficiency, ensures product quality, and meets the needs of various industries.

[0003] In certain special applications, heat exchangers need to adjust the distance between baffles according to requirements. However, existing heat exchanger baffles are fixedly installed, making it inconvenient to adjust the baffle spacing. Moreover, heat exchangers are usually one-piece units, making disassembly troublesome when internal problems occur. Therefore, this application provides a heat exchanger for pharmaceutical equipment to meet these requirements. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a heat exchanger for pharmaceutical equipment to solve the problems of existing heat exchangers where the baffles are fixedly installed, making it inconvenient to adjust the spacing of the baffles, and the fact that heat exchangers are usually one piece, making disassembly troublesome when there are internal problems.

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

[0006] A heat exchanger for pharmaceutical equipment includes a housing. A disassembly groove is provided on one side of the housing. An inlet pipe (II) and an outlet pipe (II) are fixedly connected to the two sides of the housing, respectively, leading to the interior of the housing. An inlet pipe (I) and an outlet pipe (II) are provided on the outer surface of the housing, also leading to the interior of the housing. A through groove is provided on the side of the housing away from the disassembly groove. A baffle mechanism is installed inside the housing. The baffle mechanism includes a support rod and a plurality of cross-arranged baffles (I and II) sleeved on the support rod. Both ends of the support rod are threaded with round caps. Fixed plates are provided at both ends of the interior of the housing. The baffles (I and II) are connected to the baffles... The two flow plates are located between the fixed plates. Several heat exchange tubes are also installed between the fixed plates, penetrating the first and second flow plates. The heat exchange tubes and the fixed plates, as well as the first and second flow plates, are nested together. A retaining plate is provided inside the shell near the through groove. The retaining plate is adapted to and abuts against the inner wall of the shell. Multiple sliding grooves and recesses are provided on the side of the retaining plate away from the inner wall of the shell. The first flow plate is located inside the sliding groove. The second flow plate is engaged with the recess. A recess is provided on the side of the retaining plate that abuts against the inner wall of the shell. The recess communicates with the through groove.

[0007] Preferably, the top and bottom of the through groove are provided with sliding grooves II, and a sliding rod is slidably connected inside the through groove. One end of the sliding rod is adapted to the groove I. The top and bottom of the sliding rod are fixedly connected with sliders located inside the sliding grooves II. A spring is fixedly connected to the side of the slider near the inside of the housing, and the end of the spring away from the slider abuts against the inner wall of the sliding grooves II.

[0008] Preferably, the disassembly groove has a protrusion slidably connected inside, and a cover is fixedly connected to one side of the protrusion extending out of the housing. The side of the protrusion away from the cover is a semi-circular arc shape adapted to the inside of the housing and has several slots. The slots are engaged with the baffle plate.

[0009] Preferably, a sealing gasket is fixedly connected to the connection between the protrusion and the cover, and a pulley is provided at the bottom of the cover.

[0010] Preferably, a support frame is fixedly connected to the bottom of the outer surface of the housing, a support platform is fixedly connected to one side of the support frame, and the top of the support platform abuts against the pulley.

[0011] Preferably, one side of the housing is rotatably connected to the top of the cover, which can limit the position of the cover.

[0012] Compared with the prior art, this utility model has at least the following beneficial effects:

[0013] In the above scheme, by setting up a baffle mechanism, when it is necessary to adjust the gap between baffle one and baffle two, first press the slide rod so that one end of the slide rod extends from the inside of the through groove into the groove one on the retaining plate. The slider squeezes the spring and then pushes the slide rod, allowing the slide rod to slide inside the through groove, which in turn drives the retaining plate to slide inside the shell. When the retaining plate slides, it will drive baffle two to slide on the support rod and heat exchange tube through the groove two. Baffle one is stuck by the slot on the protrusion and will not move, so that baffle one slides in the slide groove one when the retaining plate slides. This allows the movement of baffle two to shorten the gap between baffle one and baffle two. The advantage of doing this is that the distance between baffle one and baffle two can be controlled to change the flow rate of the heat exchange medium inside the shell, so that the temperature of the heat exchange medium will also be adjusted accordingly. This can be changed according to the needs of the application scenario, thus expanding the application scenarios.

[0014] By setting up a cover and a protrusion, when a problem occurs inside the shell, rotating the rotating block releases the limit on the cover, and then pulling the cover causes the protrusion to leave the shell. This, in turn, causes the first baffle plate, which is held in place by the slot on the protrusion, to move the support rod, heat exchange tube, second baffle plate, fixing plate, and clamping plate out of the shell together. This allows for the cleaning and replacement of the removed parts. To replace the heat exchange tube, simply pull it out. To replace the first and second baffle plates, simply remove the first baffle plate from the slot, remove the clamping plate, slide out the fixing plates on both sides of the heat exchange tube, and then rotate the round cover to slide the first and second baffle plates off the support rod and heat exchange tube. By setting up pulleys and a support platform, the sliding of the cover is assisted, making the process of pulling the protrusion out of the shell easier. Attached Figure Description

[0030] like Figures 1-6As shown, an embodiment of this utility model provides a heat exchanger for pharmaceutical equipment, including a housing 1. A disassembly groove 2 is provided on one side of the housing 1. An inlet pipe 6 and an outlet pipe 7, which communicate with the interior of the housing 1, are respectively fixedly connected to both sides of the housing 1. An inlet pipe 4 and an outlet pipe 5, which communicate with the interior of the housing 1, are provided on the outer surface of the housing 1. A through groove 11 is provided on the side of the housing 1 away from the disassembly groove 2. A baffle mechanism 9 is installed inside the housing 1. The baffle mechanism 9 includes a support rod 904 and a plurality of cross-shaped components sleeved on the support rod 904. The baffles 901 and 902 are arranged in a row. Both ends of the support rod 904 are threaded with round caps 905. Fixed plates 903 are installed at both ends of the interior of the shell 1. Baffles 901 and 902 are located between the fixed plates 903. Several heat exchange tubes 906 are installed between the fixed plates 903, penetrating baffles 901 and 902. The heat exchange tubes 906, fixed plates 903, and baffles 901 and 902 are nested together. A retaining device is installed inside the shell 1 near the through slot 11. Plate 907 is adapted to and abuts against the inner wall of housing 1. Multiple sliding grooves 909 and recesses 910 are provided on the side of plate 907 away from the inner wall of housing 1. A first baffle plate 901 is located inside the first sliding groove 909. A second baffle plate 902 engages with the second recess 910. A first recess 908 is provided on the side of plate 907 that abuts against the inner wall of housing 1. The first recess 908 communicates with a through groove 11. Sliding grooves 12 are provided at both the top and bottom of the through groove 11. A sliding rod 13 is slidably connected inside the through groove 11. One end of the sliding rod 13 is connected to… The groove 1 is adapted to the slide bar 13. The top and bottom of the slide bar 13 are fixedly connected to the slider 14 located inside the slide bar 12. The side of the slider 14 closest to the inside of the housing 1 is fixedly connected to the spring 15. The end of the spring 15 away from the slider 14 abuts against the inner wall of the slide bar 12. The inside of the disassembly groove 2 is slidably connected to the protrusion 8. The protrusion 8 extends out of the housing 1 and is fixedly connected to the cover 3. The side of the protrusion 8 away from the cover 3 is a semi-circular arc shape adapted to the inside of the housing 1 and has several slots 10. The slots 10 are engaged with the baffle plate 1 901.

[0031] By setting the baffle mechanism 9, when it is necessary to adjust the gap between baffle one 901 and baffle two 902, first press the slide rod 13 so that one end of the slide rod 13 extends from the inside of the through groove 11 into the groove one 908 on the clamping plate 907. The slider 14 squeezes the spring 15, and then pushes the slide rod 13 so that the slide rod 13 slides inside the through groove 11, causing the clamping plate 907 to slide inside the housing 1. When the clamping plate 907 slides, it will drive the baffle two 902 to slide on the support rod 904 and the heat exchange tube 906 through the groove two 910. When the baffle plate 901 is in motion, it is held in place by the slot 10 on the protrusion 8 and will not move. This allows the baffle plate 901 to slide within the slide groove 909 when the plate 907 slides, thereby shortening the gap between the baffle plate 902 and the baffle plate 901. The advantage of this is that the distance between the baffle plate 901 and the baffle plate 902 can be controlled to change the flow rate of the heat exchange medium inside the shell 1, so that the temperature of the heat exchange medium will also change accordingly. This can be changed according to the needs of the application scenario, thus expanding the application scenarios.

[0032] like Figures 1-3 and Figure 5 As shown, sealing gaskets 16 are fixedly connected at the connection between the protrusion 8 and the cover 3. A pulley 17 is provided at the bottom of the cover 3. A support frame 18 is fixedly connected to the bottom of the outer surface of the housing 1. A support platform 19 is fixedly connected to one side of the support frame 18. The top of the support platform 19 abuts against the pulley 17. A rotating block 20 that can limit the position of the cover 3 is rotatably connected to one side of the housing 1 at the top of the cover 3.

[0033] By setting up the cover 3 and the protrusion 8, when a problem occurs inside the housing 1, rotating the rotating block 20 releases the restriction on the cover 3, and then pulling the cover 3 causes the protrusion 8 to leave the inside of the housing 1. This causes the first baffle 901, which is held in place by the slot 10 on the protrusion 8, to move the support rod 904, heat exchange tube 906, second baffle 902, fixing plate 903, and clamping plate 907 out of the housing 1 together. This allows the removed parts to be cleaned and replaced. When replacing the heat exchange tube 906, ... The heat exchange tube 906 can be pulled out directly. To replace the first baffle 901 and the second baffle 902, simply remove the first baffle 901 from the slot 10, remove the retaining plate 907, slide out the fixing plates 903 on both sides of the heat exchange tube 906, and then rotate the round cover 905 to slide the first baffle 901 and the second baffle 902 to remove them from the support rod 904 and the heat exchange tube 906. By setting the pulley 17 and the support platform 19, the sliding of the cover 3 can be assisted, making it easier to pull the protrusion 8 away from the inside of the shell 1.

[0034] The technical solution provided by this utility model, by setting a baffle mechanism 9, when it is necessary to adjust the gap between baffle one 901 and baffle two 902, first press the slide rod 13, so that one end of the slide rod 13 extends from the inside of the through groove 11 into the groove one 908 on the card plate 907. The slider 14 compresses the spring 15, and then pushes the slide rod 13, so that the slide rod 13 slides inside the through groove 11, causing the card plate 907 to slide inside the housing 1. When the card plate 907 slides, it will drive the baffle two 902 through the groove two 910 to support the rod 904 and the heat exchanger. When the tube 906 slides, the first baffle 901 is held in place by the slot 10 on the protrusion 8 and will not move. This allows the first baffle 901 to slide within the first slide groove 909 when the plate 907 slides, thereby shortening the gap between the second baffle 902 and the first baffle 901. The advantage of this is that the distance between the first baffle 901 and the second baffle 902 can be controlled to change the flow rate of the heat exchange medium inside the shell 1, so that the temperature of the heat exchange medium will also change accordingly. This can be changed according to the needs of the application scenario, thus expanding the application scenarios.

[0035] By setting up the cover 3 and the protrusion 8, when a problem occurs inside the housing 1, rotating the rotating block 20 releases the restriction on the cover 3, and then pulling the cover 3 causes the protrusion 8 to leave the inside of the housing 1. This causes the first baffle 901, which is held in place by the slot 10 on the protrusion 8, to move the support rod 904, heat exchange tube 906, second baffle 902, fixing plate 903, and clamping plate 907 out of the housing 1 together. This allows the removed parts to be cleaned and replaced. When replacing the heat exchange tube 906, ... The heat exchange tube 906 can be pulled out directly. To replace the first baffle 901 and the second baffle 902, simply remove the first baffle 901 from the slot 10, remove the retaining plate 907, slide out the fixing plates 903 on both sides of the heat exchange tube 906, and then rotate the round cover 905 to slide the first baffle 901 and the second baffle 902 to remove them from the support rod 904 and the heat exchange tube 906. By setting the pulley 17 and the support platform 19, the sliding of the cover 3 can be assisted, making it easier to pull the protrusion 8 away from the inside of the shell 1.
