DETAILED DESCRIPTION

[0031] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0032] Existing spiral plate heat exchangers are often equipped with guide plates inside to increase the heat exchange rate. However, since the guide plates are fixed, the flow direction of the refrigerant and heat medium inside them is fixed, which causes the refrigerant and heat medium to accumulate in local areas and cannot participate in the flow, thereby reducing the heat exchange rate.

[0033] Example 1: A plate heat exchanger with an anti-internal leakage function for heating, such as Figure 1-Figure 5As shown, it includes a base 1, the base 1 is fixedly connected to the shell 2, the shell 2 is fixedly connected to the first partition 3 and the second partition 4, the first partition 3 and the second partition 4 are both spiral plates, the first partition 3 and the second partition 4 are distributed in a mosquito coil disc, the adjacent ends of the first partition 3 and the second partition 4 are fixedly connected to each other, the first partition 3 and the second partition 4 divide the shell 2 into a spiral refrigerant cavity and a spiral heat medium cavity, the top of the shell 2 is fixedly connected to the refrigerant inlet pipe 5 and the heat medium inlet pipe 6, the shell 2 The right and left sides of the outer shell are respectively fixedly connected with a refrigerant outlet pipe 7 and a heat medium outlet pipe 8. The refrigerant inlet pipe 5 and the refrigerant outlet pipe 7 are both connected to the refrigerant cavity in the shell 2, so that the refrigerant enters the refrigerant cavity along the refrigerant inlet pipe 5 and is discharged along the refrigerant outlet pipe 7. The heat medium inlet pipe 6 and the heat medium outlet pipe 8 are both connected to the heat medium cavity in the shell 2, so that the heat medium enters the heat medium cavity along the heat medium inlet pipe 6 and is discharged along the heat medium outlet pipe 8, and heat exchange is performed with the refrigerant in the refrigerant cavity in the heat medium cavity. The first partition 3 and the second partition 4 are fixedly connected. There are six fixed frames 9 connected to a linear array, and the fixed frames 9 are rotatably connected to the guide plates 10 of the linear array. A first elastic element 11 is provided between the guide plates 10 of the linear array and the adjacent fixed frames 9. The first elastic element 11 is a torsion spring. The first elastic element 11 is used to drive the adjacent guide plates 10 to reset. A pull rope 12 is fixedly connected between two adjacent guide plates 10 on the same fixed frame 9, and the pull rope 12 between the two adjacent guide plates 10 is in a entangled state with the guide plate 10 located above, and is used to pull the guide plates 10 to rotate. A driving component for driving the guide plates 10 to rotate is provided at the bottom of the shell 2, and a filtering component for filtering impurities in the refrigerant and heat medium is provided inside the shell 2. By making the rotation angle of the guide plate 10 dynamically change, and then continuously changing the guide angle of the refrigerant and heat medium, the flow direction of the refrigerant and heat medium is always changing, avoiding the flow direction being too fixed, resulting in a flow dead angle, and reducing the heat exchange rate between the two.

[0034] like Figure 1 、 Figure 5 and Figure 6As shown, the driving assembly includes a first servo motor 201, which is fixedly connected to the front side of the base 1, and the output shaft of the first servo motor 201 is fixedly connected to the first gear 202. The base 1 is rotatably connected to the rotating frame 203, and the outside of the rotating frame 203 is fixedly connected to the teeth of the annular array. The first gear 202 is transmission-connected to the rotating frame 203 through the teeth of the annular array. The first servo motor 201 drives the rotating frame 203 to rotate through the first gear 202 and the teeth of the annular array. The rotating frame 203 is provided with three groups of grooves 204 in annular arrays. The array radius of the grooves 204 of the three groups of annular arrays gradually decreases. The grooves 204 are isosceles trapezoidal grooves. The lower bottom of the grooves 204 is coplanar with the upper plane of the rotating frame 203. The bottom of the shell 2 is fixedly connected to a straight line. The six adjustment cylinders 205 of the array and the six adjustment cylinders 205 of the linear array are all slidably connected with the first piston shaft 206. A second elastic element 207 is arranged between the adjustment cylinder 205 and the adjacent first piston shaft 206. The second elastic element 207 is initially in a stretched state. The second elastic element 207 is a tension spring. The second elastic element 207 is used to drive the adjacent first piston shaft 206 to move downward. The elastic coefficient of the second elastic element 207 is greater than the sum of the elastic coefficients of the first elastic elements 11 of the adjacent linear arrays. The first piston shaft 206 and the adjacent guide plate 10 are connected through a pull rope 12, and the pull rope 12 between the two is in a wound state on the guide plate 10, so that the first piston shaft 206 moves downward and pulls the adjacent guide plate 10 to rotate through the adjacent pull rope 12.

[0035] like Figure 5 and Figure 6 As shown, the bottom of the first piston shaft 206 of the linear array is slidably connected with a mating shaft 208, and the six first piston shafts 206 of the linear array are all threadedly connected with a fixed pin shaft 209, and the fixed pin shaft 209 is limitedly matched with the adjacent mating shaft 208. The fixed pin shaft 209 slides inward along the adjacent first piston shaft 206 to squeeze and fix the adjacent mating shaft 208. The grooves 204 of the annular array are all squeezed and matched with the adjacent mating shaft 208. When the mating shaft 208 moves downward along the waist of the groove 204, the mating shaft 208 drives the first piston shaft 206 to move downward. When the mating shaft 208 slides upward along the waist of the groove 204, the first piston shaft 206 is reset.

[0036] like Figure 3 、 Figure 7 and Figure 8As shown, the filter assembly includes a second servo motor 301, which is fixedly connected to the bottom of the shell 2 through a connecting piece, and the output shaft of the second servo motor 301 is fixedly connected to the second gear 302. Two mirror-distributed filter cartridges 303 are fixedly connected in the shell 2. The two mirror-distributed filter cartridges 303 are respectively located in the refrigerant cavity and the heat medium cavity in the shell 2, and the refrigerant inlet pipe 5 and the heat medium inlet pipe 6 are respectively connected to the adjacent filter cartridges 303. The filter cartridges 303 are used to filter impurities in the refrigerant and the heat medium to prevent impurities from adhering to the first partition plate 3 and the second partition plate 4, thereby preventing the impurities from adhering to the first partition plate 3 and the second partition plate 4. Impurities block the refrigerant cavity and the heat medium cavity, causing internal leakage in the device. The filter cartridge 303 is rotatably connected to the inner shell 304, and the inner shell 304 is fixedly connected to the scraper 305 that fits the adjacent filter cartridge 303. The inner shell 304 is fixedly connected to the third gear 306 located on the outside of the outer shell 2. The mirror-distributed third gears 306 are all engaged with the second gear 302. The second servo motor 301 drives the inner shell 304 to rotate synchronously through the second gear 302 and the third gear 306, so that the inner shell 304 drives the adjacent scraper 305 to rotate and scrape off impurities attached to the inner side of the adjacent filter cartridge 303.

[0037] When heat exchange is required, the staff adjusts the distance between the six mating shafts 208 of the linear array and the adjacent first piston shaft 206 according to the flow rate of the refrigerant and the heat medium, and then adjusts the distance of the groove 204 to squeeze the mating shaft 208, and then adjusts the diversion amplitude of the guide plate 10 to avoid the refrigerant and heat medium flowing too fast, which causes excessive force on the guide plate 10 and causes damage. When the mating shaft 208 is adjusted to the required position, the staff rotates the fixing pin 209, and the fixing pin 209 moves inward along the adjacent first piston shaft 206 until the fixing pin 209 contacts the adjacent mating shaft 208 and squeezes it to fix it, and then stops rotating the fixing pin 209.

[0038] When the guide amplitude adjustment of the guide plate 10 is completed, the refrigerant inlet pipe 5 and the heat medium inlet pipe 6 are opened. At this time, the refrigerant enters the refrigerant cavity in the shell 2 along the refrigerant, and the heat medium enters the heat medium cavity in the shell 2 along the heat medium inlet pipe 6. Then the refrigerant flows along the spiral refrigerant cavity, and at the same time, the heat medium flows along the spiral heat medium cavity. At this time, the heat medium in the heat medium cavity exchanges heat with the refrigerant in the refrigerant cavity, so that the temperature of the refrigerant in the refrigerant cavity increases, and this continues until the refrigerant is discharged along the refrigerant outlet pipe 7 and the heat medium is discharged along the heat medium outlet pipe 8. When the refrigerant inlet pipe 5 and the heat medium inlet pipe 6 are opened, the first servo motor 201 is turned on, and the first servo motor 20 The output shaft of 1 drives the first gear 202 thereon to rotate synchronously. The first gear 202 drives the rotating frame 203 to rotate through the teeth of the annular array. The rotation of the rotating frame 203 drives the three groups of annular array grooves 204 thereon to rotate. When the matching shaft 208 enters the adjacent groove 204, the second elastic element 207 is compressed and drives the adjacent first piston shaft 206 to move downward. The first piston shaft 206 drives the matching shaft 208 thereon to move downward along the waist of the groove 204. The first piston shaft 206 pulls the adjacent pull rope 12. At this time, the pull rope 12 pulls the adjacent guide plate 10 to rotate, and the guide plate 10 is rotated. The flow plate 10 rotates to drive the adjacent first elastic element 11 to twist, and at the same time, the guide plate 10 pulls the pull rope 12 above it, and drives the guide plate 10 above it to rotate synchronously, and so on. The cycle continues until all the guide plates 10 rotate to guide the refrigerant and heat media, and so on until the matching shaft 208 moves to the upper bottom of the adjacent groove 204, which is the maximum angle of rotation of the guide plate 10. Then, when the matching shaft 208 contacts the other waist, the matching shaft 208 slides along the other waist to drive the adjacent first piston shaft 206 to reset, and the second elastic element 207 begins to stretch. At this time, the first piston shaft The pull rope 12 between 206 and the adjacent guide plate 10 is loose, and at the same time, the first elastic element 11 is reset to drive the guide plate 10 to reset and reel in the pull rope 12, so that the mating shaft 208 is separated from the adjacent groove 204. At this time, the second elastic element 207 is stretched to the initial state, and the rotation angle of the guide plate 10 is in dynamic change, thereby continuously changing the diversion angle of the refrigerant and the heat medium, so that the flow direction of the refrigerant and the heat medium in the refrigerant cavity and the heat medium cavity respectively is always changing, avoiding the flow direction of the refrigerant and the heat medium being too fixed, resulting in flow dead angles, and reducing the heat exchange rate between the two.

[0039] When heat exchange begins, impurities in the refrigerant and heat medium are filtered into the interior of the filter cartridge 303 and adhere to its inner side, preventing impurities from adhering to the first partition plate 3 and the second partition plate 4 to form dirt that blocks the refrigerant cavity and the heat medium cavity, causing local pressure to increase and causing leakage. When the refrigerant inlet pipe 5 and the heat medium inlet pipe 6 are opened, the staff turns on the second servo motor 301, and the output shaft of the second servo motor 301 drives the second gear 302 thereon to rotate, and the second gear 302 drives the two third gears 306 to rotate synchronously. The rotation of the third gear 306 drives the adjacent inner shell 304 to rotate, and the inner shell 304 drives the scraper 305 thereon to scrape off impurities attached to the inner side of the filter cartridge 303, preventing impurities from adhering to the inside of the filter cartridge 303, and reducing the circulation of the refrigerant and heat medium.

[0040] When the heat exchange is completed, the staff closes the refrigerant inlet pipe 5 and the heat medium inlet pipe 6, and turns off the first servo motor 201 and the second servo motor 301. When heat exchange is performed again, the above steps are repeated, and the device is disassembled regularly to clean the impurities in the two filter cartridges 303.

[0041] Example 2: Based on Example 1, Figures 8-10 As shown, it also includes two knocking components with mirror distribution and used to separate impurities from adjacent filter cartridges 303. The knocking components are arranged inside the adjacent filter cartridges 303. The knocking components include an inner shaft 307. The inner shaft 307 is fixedly connected to the bottom of the outer shell 2 through a connecting piece. The inner shaft 307 is fixedly connected to a first fixed plate 308 of a linear array. The first fixed plate 308 of the linear array is located inside the adjacent inner shell 304. The outside of the inner shell 304 is fixedly connected to a first fixed cylinder 309 of a linear array. The first fixed plate 308 is provided with a first slide 310. The first slide 310 is composed of four straight grooves of an annular array and four oblique grooves of an annular array alternating head to tail. The oblique groove is longer than the straight groove, and the symmetry line of the straight groove coincides with the radius line of the adjacent first fixed plate 308. The first fixed cylinder 309 is slidably connected to the through groove. The second piston shaft 311 passes through the adjacent inner shell 304, and a third elastic element 312 is provided between the first fixed cylinder 309 and the adjacent second piston shaft 311. The third elastic element 312 is a spring. The third elastic element 312 is used to drive the adjacent second piston shaft 311 to reset. The second piston shaft 311 is fixedly connected to the first clamping shaft 313 located inside the adjacent inner shell 304. The first clamping shaft 313 is slidingly connected to the adjacent first slide groove 310. When the first clamping shaft 313 slides along the oblique groove of the first slide groove 310, the first clamping shaft 313 drives the adjacent second piston shaft 311 to slide into the adjacent inner shell 304. When the first clamping shaft 313 slides in the straight groove of the first slide groove 310, the third elastic element 312 pushes the adjacent second piston shaft 311 to reset, so that the second piston shaft 311 performs linear reciprocating motion.

[0042] like Figure 9 and Figure 11 As shown, it also includes two collecting components with mirror distribution and for collecting impurities, the collecting components are arranged in adjacent inner shells 304, and the collecting components include a second fixed cylinder 401 in a linear array, the second fixed cylinders 401 in the linear array are all fixedly connected to the outside of the adjacent inner shells 304, and are located on the same side as the adjacent scraper 305, the second fixed cylinder 401 is slidably connected to a third piston shaft 402 that passes through the adjacent inner shell 304, a fourth elastic element 403 is arranged between the third piston shaft 402 and the adjacent second fixed cylinder 401, the fourth elastic element 403 is a spring, and the fourth elastic element 403 is used to drive the adjacent third piston shaft 402 to reset, the third piston shaft 402 is fixedly connected to the second clamping shaft 404 located inside the adjacent inner shell 304, the inner shaft 307 is fixedly connected to the second fixed plate 405 in the linear array, and the second fixed plate 405 of the linear array is intersected with the first fixed plate 308 of the linear array. The second fixing plate 405 is alternately distributed, and a second slide groove 406 is provided with an adjacent second clamping shaft 404 in sliding connection. The second slide groove 406 is formed by a straight groove and a spiral groove connected end to end. When the second clamping shaft 404 slides along the spiral groove on the adjacent second slide groove 406, the second clamping shaft 404 drives the adjacent third piston shaft 402 to slide into the adjacent inner shell 304. The filter cartridge 303 is fixedly connected and connected to the collection shell 407. The straight groove of the second slide groove 406 is located on the same side as the adjacent collection shell 407, and is used to reset the third piston shaft 402 at the adjacent collection shell 407 and push impurities into the adjacent collection shell 407. The inner shell 304 is provided with a limiting component for preventing impurities from swimming. By pushing and impacting the impurities scraped off by the scraper 305 to the collection shell 407 for storage, the impurities in the filter cartridge 303 are prevented from gradually increasing, resulting in a gradual increase in the probability of blockage of the filter cartridge 303 and a reduction in the heat exchange rate.

[0043] like Figure 12 As shown, the limiting assembly includes a sealing plate 408, which is slidably connected to the adjacent filter cartridge 303, and the sealing plate 408 is sealed with the adjacent collection shell 407. A fifth elastic element 409 is provided between the collection shell 407 and the adjacent sealing plate 408. The fifth elastic element 409 is a spring for driving the adjacent sealing plate 408 to reset. The second fixed cylinder 401 is slidably connected to the side away from the adjacent scraper 305 with a block 410, and the block 410 is connected to the adjacent second fixed cylinder 401. A spring (not shown in the figure) is provided, which is used to drive the adjacent block 410 to reset. The sealing plate 408 is provided with a blind hole that cooperates with the block 410. The second fixed cylinder 401 drives the upper block 410 to dock with the blind hole, and pushes the sealing plate 408 to open the adjacent collection shell 407. At this time, impurities are flushed into the collection shell 407, and the collection shell 407 is closed to prevent the impurities in the collection shell 407 from floating into the adjacent filter cartridge 303 again, resulting in a decrease in the flow rate of the filter cartridge 303.

[0044] When the inner shell 304 rotates and drives the scraper 305 on it to scrape impurities inside the adjacent filter cylinder 303, the inner shell 304 drives the first fixed cylinder 309 in the linear array on it to rotate synchronously. The rotation of the first fixed cylinder 309 drives the second piston shaft 311 inside it to rotate synchronously. The second piston shaft 311 drives the first clamping shaft 313 on it to rotate synchronously. The first clamping shaft 313 slides along the adjacent first sliding groove 310. When the first clamping shaft 313 slides along the oblique groove of the first sliding groove 310, the first clamping shaft 313 drives the adjacent second piston shaft 311 to slide inward. At this time, the third elastic element 312 is compressed. When the first clamping shaft 313 slides to the straight groove, the third elastic element 312 resets and pushes the adjacent second piston shaft 311 to quickly reset and knock on the adjacent filter cylinder 303. The filter cylinder 303 is knocked to generate a vibration force, so that the impurities attached to it are separated from the filter cylinder 303 by the vibration force.

[0045] When the inner shell 304 drives the first fixed cylinder 309 on it to rotate, it synchronously drives the second fixed cylinder 401 of the linear array on it to rotate, and the second fixed cylinder 401 drives the third piston shaft 402 inside it to rotate synchronously, and the third piston shaft 402 drives the second clamping shaft 404 on it to rotate, and the second clamping shaft 404 rotates and slides along the adjacent second sliding groove 406. When the second clamping shaft 404 slides along the spiral groove of the adjacent second sliding groove 406, the second clamping shaft 404 drives the adjacent third piston shaft 402 to slide inward, and at the same time the fourth elastic element 403 is compressed, so that the block 410 on the second fixed cylinder 401 is docked with the blind hole on the sealing plate 408. At this time, the second fixed cylinder 401 drives the sealing plate 408 to rotate synchronously through the block 410, the fifth elastic element 409 is compressed, and the sealing plate 408 gradually opens the adjacent collecting shell 407. Then, when the second fixed cylinder 401 rotates to face the collecting shell 4 At 07, the third piston shaft 402 slides along the spiral groove of the adjacent second slide groove 406 to the straight groove. At this time, the fourth elastic element 403 resets and drives the adjacent third piston shaft 402 to reset synchronously. At this time, the third piston shaft 402 impacts the impurities scraped by the adjacent scraper 305 into the collection shell 407, and then the second fixed cylinder 401 continues to rotate until the sealing plate 408 slides to the limit state, and then the block 410 compresses the adjacent spring under the extrusion force and separates from the blind hole on the sealing plate 408. At this time, the fifth elastic element 409 resets and drives the adjacent sealing plate 408 to block the adjacent collection shell 407 again, and so on. The cycle is repeated, and the impurities scraped by the scraper 305 are diverted to the collection shell 407 and pushed into the collection shell 407 for storage, thereby avoiding the gradual increase of impurities in the filter cartridge 303, resulting in a gradual increase in the probability of the filter cartridge 303 being blocked, thereby reducing the heat exchange rate, and so on until the heat exchange is completed.
