Description

Technical Field

[0001] The invention relates to the technical field of heat exchange devices, in particular to a stainless steel heat exchange plate for concentrate drying and an assembly structure thereof. Background Art

[0002] In the concentrate drying process, the plate heat exchanger and the drying rotary kiln form a synergistic relationship through heat energy transfer and medium processing, jointly optimizing drying efficiency and energy consumption. The plate heat exchanger is a new type of high-efficiency heat exchanger made of a certain number of metal plates pressed into a corrugated shape. Narrow corrugated channels are formed between the plates, and heat exchange is carried out through the thermal conductivity of the metal plates. Compared with the traditional shell and tube heat exchanger, its heat transfer coefficient is much higher under the same flow resistance and pump power consumption, and it occupies a smaller area. It has a trend of replacing shell and tube heat exchangers within the applicable scope. The existing plate heat exchanger usually fixes the movable splints clamped on the plates with multiple bolts so that the movable splints clamp the plates. When the plates need to be maintained, it is necessary to manually unscrew these bolts one by one to open the movable splints clamped on the plates or clamp the opened movable splints on the plates. This process takes up most of the maintenance time, thereby reducing work efficiency. When the plates are exchanging heat, the medium (such as water) flowing through the plates usually carries some impurities. These impurities will adhere to the inner wall of the through-holes when the medium flows through the through-holes of the plates to form dirt. As these dirt accumulates, the through-holes of the plates will eventually be blocked, causing the plates to fail to work normally, requiring frequent maintenance work on the plates.

DETAILED DESCRIPTION

[0031] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention. Example 1

[0032] See also Figures 1-12A stainless steel heat exchange plate for concentrate drying and its assembly structure, including a main body 1, on which a hot medium inlet 12, a hot medium outlet 13, a cold medium inlet 14 and a cold medium outlet 15 are respectively provided. The main body 1 is provided with a plate 3, a cleaning assembly 4 and a clamping assembly 5. Several plates 3 are stacked on the main body 1 in sequence. Four through holes 32 are opened on the plate 3, each through hole 32 corresponds to the hot medium inlet 12, the hot medium outlet 13, the cold medium inlet 14 and the cold medium outlet 15 respectively. The through hole 32 is used to circulate the medium passing through the plate 3. A support rod 34 is provided in the through hole 32. The cleaning assembly 4 includes a connecting sleeve 41, a push rod 45 and a scraper 46. The connecting sleeve 41 is installed on the support rod 34. A turbine is installed on the connecting sleeve 41 42, a push rod 45 is arranged on the outside of the turbine 42, and a scraper 46 is connected to the push rod 45. The push rod 45 pushes the scraper 46 to contact the side wall of the through hole 32. When the medium passes through the through hole 32, the turbine 42 is driven to drive the scraper 46 on the push rod 45 to rotate, so that the scraper 46 scrapes off the dirt on the inner wall of the through hole 32. The clamping assembly 5 includes a movable splint 51, a columnar pressure block 54 and a driving rod 56. The movable splint 51 is installed on the main body 1. A fixed sleeve 52 is provided on the side of the movable splint 51 away from the plate 3. The columnar pressure block 54 is connected to the fixed sleeve 52. The driving rod 56 is connected to the columnar pressure block 54. When the driving rod 56 rotates forward, it drives the columnar pressure block 54 to push the movable splint 51 to move toward the plate 3, thereby pressing the stacked plates 3.

[0033] In which, when in use, the hot medium and the cold medium enter the corresponding through holes 32 on the plate 3 through the hot medium inlet 12 and the cold medium inlet 14 respectively, and then the hot medium and the cold medium flow into the channels formed between the plates 3 and 3 through the through holes 32. After that, the hot medium is discharged from the hot medium outlet 13, and the cold medium is discharged from the cold medium outlet 15. In this process, the cold medium and the hot medium complete heat exchange. At the same time, the impurities carried by the two media will adhere to the inner wall of the through hole 32 to form dirt. At this time, the cleaning component 4 will clean the dirt in the through hole 32. In this process, the flowing medium will drive the turbine 42 to rotate, and the rotating turbine 42 will drive the scraper 46 on the push rod 45 to scrape the dirt on the inner wall of the through hole 32. The scraped dirt The plate 3 will be carried out by the flowing medium and discharged through the hot medium outlet 13 or the cold medium outlet 15. When the plate 3 needs to be maintained, the driving rod 56 is rotated in the reverse direction so that the driving rod 56 pulls the movable splint 51 pressed on the plate 3 away from the plate 3 through the columnar pressure block 54, and the clamped plate 3 is loosened, so that the staff can remove the plate 3 from the main body 1. After completing the maintenance, the staff places the plate 3 on the main body 1 again. After placing the plate 3, the driving rod 56 is rotated forward again so that the driving rod 56 pushes the movable splint 51 toward the plate 3 through the columnar pressure block 54, thereby clamping the plate 3 stacked on the main body 1 again, so that a channel for medium circulation is formed between the plates 3 and the plates 3, so that the device can be put into use again.

[0034] The difference from the above embodiment is that the main body 1 includes a fixing plate 11 , and a hot medium inlet 12 , a hot medium outlet 13 , a cold medium inlet 14 and a cold medium outlet 15 are respectively opened at the four corners of the fixing plate 11 .

[0035] The difference from the above embodiment is that the main body 1 also includes a pillar 16, a threaded sleeve 161 is fixedly installed on the pillar 16, two guide rods 17 are fixedly connected between the pillar 16 and the fixed plate 11, and the two guide rods 17 are respectively located at the upper and lower ends of the pillar 16, and four sliding rods 18 are fixedly connected between the pillar 16 and the upper and lower ends of the fixed plate 11, and a pair of sliding rods 18 are provided on both sides of the guide rod 17.

[0036] The difference from the above embodiment is that the plate 3 is made of stainless steel, and recesses 31 are provided at the upper and lower ends of the plate 3. The two recesses 31 correspond to the two guide rods 17 respectively. The plate 3 is slidably mounted on the guide rods 17 through the recesses 31. The four through holes 32 on the plate 3 are respectively located at the four corners of the plate 3. A fixing frame 33 is provided at both ends of each through hole 32. The fixing frame 33 is fixedly connected to the plate 3, and a support rod 34 is fixedly connected between the fixing frames 33 at both ends of the through hole 32.

[0037] Among them, the plate 3 is slidably installed between the two guide rods 17 through the notches 31 at the upper and lower ends. After several plates 3 are placed on the guide rods 17 in turn, the driving rod 56 drives the fixed splint to push several plates 3 to slide on the guide rods 17, approach each other, and finally stack them tightly together, so that channels for medium circulation are formed between the plates 3 and the plates 3. The plates 3 are made of stainless steel, so that the plates 3 have extremely high corrosion resistance, high strength and hardness, so that the plates 3 can be used for a long time in harsh environments and are not easily deformed or damaged, thereby improving the service life of the plates 3.

[0038] The difference from the above embodiment is that the connecting sleeve 41 is slidably mounted on the support rod 34, and the turbine 42 is rotatably mounted on the connecting sleeve 41, wherein the turbines 42 in the two through holes 32 corresponding to the hot medium inlet 12 and the cold medium inlet 14 are located at one end of the through hole 32 close to the fixed plate 11, and the turbines 42 in the two through holes 32 corresponding to the hot medium outlet 13 and the cold medium outlet 15 are located at one end of the through hole 32 away from the fixed plate 11, so that the turbine 42 corresponds to the flow direction of the medium, and a return spring 47 is fixedly connected between one end of the connecting sleeve 41 and one of the fixing frames 33, and the return spring 47 pushes the connecting sleeve 41 to contact the other fixing frame 33.

[0039] Among them, when the medium flows through the through hole 32, the flowing medium will drive the turbine 42 to rotate on the connecting sleeve 41, so that the turbine 42 drives the scraper 46 to scrape the dirt on the side wall of the through hole 32. At the same time, the flowing medium will also apply thrust to the turbine 42, so that the turbine 42 moves in the same direction as the medium on the support rod 34 through the connecting sleeve 41 and compresses the return spring 47. In this process, when the medium impacts the fan blades of the turbine 42, the thrust of the medium to push the turbine 42 to move will be reduced, and the elastic force of the compressed return spring 47 is greater than the thrust of the medium at this time, so that the return spring 47 recovers its deformation and pushes the turbine 42 to move in the opposite direction back to its original position. After the spring recovers its deformation, the flowing medium pushes the turbine 42 to move again and compresses the return spring 47. The above process is repeated, so that the turbine 42 drives the scraper 46 to rotate while also driving the scraper 46 to move back and forth in the through hole 32, thereby improving the cleaning effect of the scraper 46.

[0040] The difference from the above embodiment is that a plurality of storage boxes 43 are fixedly connected to the outer side of the turbine 42, and the plurality of storage boxes 43 are evenly arranged in a circular shape on the turbine 42. A support spring 44 is fixedly connected inside the storage box 43, and the lower end of the push rod 45 is slidably installed in the storage box 43. The bottom of the push rod 45 is in conflict with the support spring 44, and the scraper 46 is fixedly installed at the upper end of the push rod 45. The support spring 44 pushes the push rod 45 out of the storage box 43, so that the scraper 46 is in conflict with the inside of the through hole 32.

[0041] Among them, when cleaning dirt, the support spring 44 of the storage box 43 always pushes the push rod 45 to the top of the storage box 43, ensuring that the scraper 46 can be in close contact with the side wall of the through hole 32, and can effectively scrape off the dirt, thereby further improving the cleaning effect of the scraper 46. When a protrusion that is difficult to scrape off appears on the inner wall of the through hole 32, the scraper 46 will adaptively push the push rod 45 to retract into the storage box 43 during the process of scraping dirt, pass through the protrusion, and compress the support spring 44. After the scraper 46 passes, the compressed support spring 44 pushes the push rod 45 out of the storage box 43 again, so that the scraper 46 contacts the side wall of the through hole 32 again, thereby avoiding the scraper 46 scratching the inner wall of the through hole 32 and damaging itself, thereby ensuring the normal operation of the device. Example 2

[0042] The difference from the above embodiment is that the movable splint 51 is slidably installed on the slide rod 18, the fixed sleeve 52 is fixedly connected to the movable splint 51, and a plurality of limit plates 53 are evenly arranged on the outer side of the fixed sleeve 52 in a circular shape. The limit plates 53 are fixedly connected to the movable splint 51, and a gap is provided between the limit plates 53 and the fixed sleeve 52. The four corners of the movable splint 51 are fixedly connected with sliding rails 511.

[0043] The gap between the limiting plate 53 and the fixing sleeve 52 allows the cylindrical pressing block 54 to pass through.

[0044] The difference from the above embodiment is that the interior of the cylindrical pressure block 54 is hollow, and the cylindrical pressure block 54 is slidably installed on the fixed sleeve 52. A number of limit grooves 541 are provided on the outside of the cylindrical pressure block 54, and the limit plate 53 is slidably installed in the limit groove 541. The outside of the cylindrical pressure block 54 is also fixedly connected to a mounting seat 542, and the mounting seat 542 corresponds to the slide rail 511. A pressure spring 55 is provided in the fixed sleeve 52, and the two ends of the pressure spring 55 are respectively fixedly connected to the side wall of the movable splint 51 and the inner wall of the cylindrical pressure block 54. The driving rod 56 is a threaded rod, and one end of the driving rod 56 is rotatably connected to the cylindrical pressure block 54. The other end of the driving rod 56 is assembled in the threaded sleeve 161 and extends out of the threaded sleeve 161. A turntable 57 is fixedly connected to the protruding end of the driving rod 56.

[0045] When the movable splint 51 is needed to clamp the plate 3, the driving rod 56 is rotated forward so that the driving rod 56 pushes the cylindrical pressure block 54 under the cooperation of the thread, so that the movable splint 51 moves toward the plate 3. At this time, the pressure spring 55 in the fixed sleeve 52 pushes the cylindrical pressure block 54 to the end of the fixed sleeve 52 close to the support 16. After the movable splint 51 pushes several plates 3 to be stacked together, the movable splint 51 no longer moves. At this time, the driving rod 56 is continued to be rotated so that the cylindrical pressure block 54 approaches the fixed splint and compresses the pressure spring 55. After the cylindrical pressure block 54 moves to the end of the fixed sleeve 52 close to the movable splint 51, the driving rod 56 is stopped. The spring 44 applies pressure to the movable splint 51, so that the several plates 3 are stacked more tightly together. When the movable splint 51 needs to release the clamped plate 3, the drive rod 56 is rotated in the opposite direction by the turntable 57, so that the drive rod 56 pulls the columnar pressure block 54 toward the pillar 16 with the cooperation of the thread. After the columnar pressure block 54 moves from one end of the fixed sleeve 52 close to the movable splint 51 to the other end of the fixed sleeve 52, the compressed pressure spring 55 recovers its deformation, and the columnar pressure block 54 pulls the movable splint 51 away from the plate 3, loosening the clamped plate 3. Through the cooperation of the limit plate 53 and the limit groove 541, the columnar pressure block 54 can move linearly on the fixed sleeve 52.

[0046] The difference from the above embodiment is that the clamping assembly 5 further includes a pressure rod 58 , one end of which is rotatably connected to the mounting seat 542 , and the other end of the pressure rod 58 is rotatably connected to a pressure plate 59 , which is rotatably mounted on the slide rail 511 .

[0047] Among them, when the columnar pressure block 54 is located at one end of the fixed sleeve 52 close to the pillar 16, the pressure rod 58 pulls the pressure plate 59 to the end of the slide rail 511 close to the fixed sleeve 52. When the columnar pressure block 54 moves toward the end of the fixed sleeve 52 close to the movable splint 51, the pressure rod 58 pushes the pressure plate 59 to move toward the other end of the slide rail 511, and applies pressure to the corners of the movable splint 51 through the pressure plate 59. When the movable splint 51 clamps the plate 3, the cooperation between the columnar pressure block 54, the pressure rod 58 and the pressure plate 59 enables the movable splint 51 to evenly apply pressure to the plate 3, ensuring that several plates 3 can be stacked tightly together.

[0048] The present invention also provides an assembly structure using a concentrate-dried stainless steel heat exchange plate, and the specific steps are: first, the cold and hot media are respectively introduced from the cold medium inlet 14 and the hot medium inlet 12 through the corresponding through holes 32 into the channels between the plates 3 and the plates 3, so that the two media are heat exchanged, and then the two media are discharged from the cold medium outlet 15 and the hot medium outlet 13 respectively. During the heat exchange process, the cleaning component 4 in the through hole 32 drives the scraper 46 through the turbine 42 to scrape off the dirt on the side wall of the through hole 32, so that the through hole 32 of the plate 3 remains unobstructed. When the plate 3 needs to be maintained, the drive rod 56 of the clamping component 5 is rotated so that the drive rod 56 drives the movable clamp 51 through the cylindrical pressure block 54 to quickly loosen or clamp the plate 3.

[0049] Working principle: When in use, the hot medium and the cold medium enter the corresponding through-holes 32 on the plate 3 through the hot medium inlet 12 and the cold medium inlet 14 respectively, and then the hot medium and the cold medium flow into the channels formed between the plates 3 and 3 through the through-holes 32. After that, the hot medium is discharged from the hot medium outlet 13, and the cold medium is discharged from the cold medium outlet 15. In this process, the cold medium and the hot medium complete the heat exchange. At the same time, the impurities carried by the two media will adhere to the inner wall of the through-hole 32 to form dirt. At this time, the cleaning component 4 will clean the dirt in the through-hole 32. In this process, the flowing medium will drive the turbine 42 to rotate on the connecting sleeve 41, so that the turbine 42 drives the scraper 46 to scrape the dirt on the side wall of the through-hole 32. At the same time, the flowing medium will also apply thrust to the turbine 42, so that the turbine The wheel 42 moves in the same direction as the medium on the support rod 34 through the connecting sleeve 41 and compresses the return spring 47. During this process, when the medium impacts the fan blades of the turbine 42, the thrust of the medium pushing the turbine 42 to move is reduced. The elastic force of the compressed return spring 47 is now greater than the thrust of the medium, so that the return spring 47 recovers its deformation and pushes the turbine 42 to move in the opposite direction back to its original position. After the spring recovers its deformation, the flowing medium pushes the turbine 42 to move again and compresses the return spring 47. The above process is repeated, so that the turbine 42 drives the scraper 46 to rotate and also drives the scraper 46 to reciprocate in the through hole 32, thereby improving the cleaning effect of the scraper 46. The scraped dirt will be carried out of the plate 3 by the flowing medium and discharged through the hot medium outlet 13 or the cold medium outlet 15.

[0050] When it is necessary to maintain the plate 3, the drive rod 56 is rotated in the opposite direction by the turntable 57, so that the drive rod 56 pulls the columnar pressing block 54 toward the pillar 16 under the cooperation of the thread. After the columnar pressing block 54 moves from one end of the fixed sleeve 52 close to the movable splint 51 to the other end of the fixed sleeve 52, the compressed pressure spring 55 recovers its deformation, and the columnar pressing block 54 pulls the movable splint 51 away from the plate 3, loosening the clamped plate 3, so that the staff can remove the plate 3 from the main body 1. After the maintenance is completed, , the staff then places the plate 3 on the main body 1. After placing the plate 3, the staff rotates the driving rod 56 in the forward direction, so that the driving rod 56 pushes the cylindrical pressing block 54 under the cooperation of the thread, so that the movable splint 51 moves toward the plate 3. At this time, the pressure spring 55 in the fixed sleeve 52 pushes the cylindrical pressing block 54 to the end of the fixed sleeve 52 close to the support 16. After the movable splint 51 pushes several plates 3 to be stacked together, the movable splint 51 no longer moves. At this time, the driving rod 56 is continued to be rotated so that the cylindrical pressing block 54 approaches the fixed splint and compresses the pressing spring 55. After the cylindrical pressing block 54 moves to the end of the fixed sleeve 52 close to the movable splint 51, the driving rod 56 stops rotating. At this time, the compressed supporting spring 44 applies pressure to the movable splint 51, so that the plates 3 are stacked more tightly together to form a channel for the flow of the medium, so that the device can be put into use again. Among them, when the cylindrical pressing block 54 is located at the end of the fixed sleeve 52 close to the pillar 16, the pressing rod 58 pulls the pressing plate 59 to The slide rail 511 is close to one end of the fixed sleeve 52. When the columnar pressure block 54 moves toward one end of the fixed sleeve 52 close to the movable splint 51, the pressure rod 58 pushes the pressure plate 59 to move toward the other end of the slide rail 511, and applies pressure to the corners of the movable splint 51 through the pressure plate 59. When the movable splint 51 clamps the plate 3, the columnar pressure block 54 cooperates with the pressure rod 58 and the pressure plate 59, so that the movable splint 51 can evenly apply pressure to the plate 3, ensuring that several plates 3 can be stacked tightly together.
