Description

Technical Field

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

[0002] In the concentrate drying process, a plate heat exchanger and a drying rotary kiln form a synergistic relationship through heat energy transfer and medium treatment to jointly optimize drying efficiency and energy consumption. The plate heat exchanger is a new type of high-efficiency heat exchanger formed by stacking a certain number of metal plate sheets pressed into corrugated shapes. Narrow corrugated channels are formed between the plate sheets, and heat exchange is carried out through the heat conductivity of the metal plate sheets. Compared with the traditional shell-and-tube heat exchanger, under the same flow resistance and pump power consumption, its heat transfer coefficient is much higher, and it occupies a small area. There is a trend to replace the shell-and-tube heat exchanger within the applicable range. The existing plate heat exchanger usually fixes the movable clamping plates sandwiched between the plate sheets through a plurality of bolts, so that the movable clamping plates clamp the plate sheets. When it is necessary to maintain the plate sheets, it is necessary for workers to twist these bolts one by one manually to open the movable clamping plates sandwiched between the plate sheets or clamp the opened movable clamping plates on the plate sheets. This process takes up most of the maintenance time, thus reducing work efficiency. Moreover, when the plate sheets are conducting heat exchange, the medium (such as water) flowing through the plate sheets usually carries some impurities. These impurities will adhere to the inner wall of the through holes of the plate sheets to form dirt when the medium flows through the through holes of the plate sheets. With the accumulation of these dirt, the through holes of the plate sheets will eventually be blocked, resulting in the abnormal operation of the plate sheets and making the plate sheets need to be maintained frequently.

[0015] 2. For the stainless steel heat exchange plate for concentrate drying and its assembly structure, through the setting of the cleaning component, when the medium flows in the through-hole of the plate and the impurities it carries adhere to the inner wall of the through-hole, the turbine of the cleaning component will be driven by the flowing medium, so that the turbine drives the scraper to rotate on the inner wall of the through-hole, scraping off the dirt adhering to the inner wall of the through-hole, thus ensuring the normal use of the plate. And in this process, the medium will also push the rotating turbine to reciprocate on the support rod through the connecting sleeve, so that the scraper can scrape the dirt more comprehensively, further improving the cleaning effect of the scraper.

[0018] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention. Embodiment 1

[0019] Please refer to Figures 1 - 12, A stainless steel heat exchange plate for concentrate drying and its assembly structure, including a main body 1, on which there are respectively a heat medium inlet 12, a heat medium outlet 13, a cold medium inlet 14 and a cold medium outlet 15. A plate 3, a cleaning component 4 and a clamping component 5 are arranged on the main body 1. A number of plates 3 are stacked on the main body 1 in sequence. Four through holes 32 are opened on the plate 3, and each through hole 32 corresponds to the heat medium inlet 12, the heat medium outlet 13, the cold medium inlet 14 and the cold medium outlet 15 respectively. The through holes 32 are used for the medium flowing through the plate 3. A support rod 34 is arranged in the through hole 32. The cleaning component 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 42 is installed on the connecting sleeve 41, the push rod 45 is arranged outside the turbine 42, and the scraper 46 is connected to the push rod 45. The push rod 45 pushes the scraper 46 to abut against the side wall of the through hole 32. When the medium passes through the through hole 32, it drives the turbine 42 to drive the scraper 46 on the push rod 45 to rotate, so that the scraper 46 scrapes the dirt on the inner wall of the through hole 32. The clamping component 5 includes a movable clamping plate 51, a cylindrical pressing block 54 and a driving rod 56. The movable clamping plate 51 is installed on the main body 1. A fixed sleeve 52 is arranged on the side of the movable clamping plate 51 away from the plate 3. The cylindrical pressing block 54 is connected to the fixed sleeve 52, and the driving rod 56 is connected to the cylindrical pressing block 54. When the driving rod 56 rotates forward, it drives the cylindrical pressing block 54 to push the movable clamping plate 51 to move towards the plate 3 direction, and presses a number of plates 3 stacked together.

[0020] Among them, during use, the hot medium and the cold medium respectively enter the corresponding through holes 32 on the plate 3 through the hot medium inlet 12 and the cold medium inlet 14. Subsequently, the hot medium and the cold medium flow into the channels formed between several plates 3 through the through holes 32. After that, the hot medium is discharged from the hot medium outlet 13, while the cold medium is discharged from the cold medium outlet 15. During this process, the cold medium and the hot medium complete heat exchange. At the same time, impurities carried in the two media will adhere to the inner wall of the through hole 32 to form dirt. At this time, the cleaning assembly 4 will clean the dirt in the through hole 32. During 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 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. When the plate 3 needs to be maintained, by rotating the driving rod 56 in the reverse direction, the driving rod 56 will pull the movable clamping plate 51 pressing on the plate 3 away from the plate 3 through the cylindrical pressing block 54, 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 will place the plate 3 on the main body 1 again. After placing the plate 3, rotate the driving rod 56 in the forward direction, so that the driving rod 56 will push the movable clamping plate 51 to move towards the plate 3 through the cylindrical pressing block 54, thereby clamping the plates 3 stacked on the main body 1 again, so that a channel for the medium to flow through is formed between the plates 3, enabling the device to be put into use again.

[0021] The difference from the above embodiment is that the main body 1 includes a fixed 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 fixed plate 11.

[0022] The difference from the above embodiment is that the main body 1 further includes a support column 16, a threaded sleeve 161 is fixedly installed on the support column 16, two guide rods 17 are fixedly connected between the support column 16 and the fixed plate 11, the two guide rods 17 are respectively located at the upper and lower ends of the support column 16, and four slide rods 18 are fixedly connected between the upper and lower ends of the support column 16 and the fixed plate 11. A pair of slide rods 18 are respectively arranged on both sides of the guide rod 17.

[0023] The difference from the above embodiment is that the plate 3 is made of stainless steel, concave openings 31 are opened at both the upper and lower ends of the plate 3, the two concave openings 31 respectively correspond to the two guide rods 17, the plate 3 is slidably installed on the guide rod 17 through the concave openings 31, the four through holes 32 on the plate 3 are respectively located at the four corners of the plate 3, fixed frames 33 are provided at both ends of each through hole 32, the fixed frames 33 are fixedly connected to the plate 3, and a support rod 34 is fixedly connected between the fixed frames 33 at both ends of the through hole 32.

[0024] Among them, the plate 3 is slidably installed between two guide rods 17 through the notches 31 at the upper and lower ends. After a number of plates 3 are sequentially placed on the guide rods 17, the driving rod 56 drives the fixed clamping plate to push a number of plates 3 to slide on the guide rods 17 and approach each other, and finally stack tightly together, forming a channel for the medium to flow between the plates 3. Moreover, the plate 3 made of stainless steel material has extremely high corrosion resistance, and relatively high strength and hardness, enabling the plate 3 to be used for a long time in a harsh environment without being easily deformed or damaged, thereby improving the service life of the plate 3.

[0025] The difference from the above embodiment is that the connecting sleeve 41 is slidably installed on the support rod 34, and the turbine 42 is rotatably installed on the connecting sleeve 41. Among them, 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 holes 32 close to the fixed plate 11, while 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 holes 32 far from the fixed plate 11, so that the turbines 42 are corresponding in the flowing direction of the medium. 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 abut against the other fixing frame 33.

[0026] 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 scraping plate 46 to scrape the dirt on the side wall of the through hole 32. At the same time, the flowing medium will also exert a thrust on 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 restores its deformation and pushes the turbine 42 to move back to its original position. After the spring restores its deformation, the flowing medium pushes the turbine 42 to move again and compresses the return spring 47. Repeating the above process, while the turbine 42 drives the scraping plate 46 to rotate, it will also drive the scraping plate 46 to reciprocate in the through hole 32, thereby improving the cleaning effect of the scraping plate 46.

[0027] The difference from the above embodiment is that a number of storage boxes 43 are fixedly connected to the outside of the turbine 42. The number of storage boxes 43 is evenly arranged in a circular shape on the turbine 42. A support spring 44 is fixedly connected in the storage box 43. The lower end of the push rod 45 is slidably installed in the storage box 43. The bottom of the push rod 45 abuts against the support spring 44. The scraping plate 46 is fixedly installed at the upper end of the push rod 45. The support spring 44 pushes the push rod 45 to extend out of the storage box 43, so that the scraping plate 46 abuts against the inside of the through hole 32.

[0028] Among them, when cleaning the 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 scraping plate 46 can be in close contact with the side wall of the through hole 32, and can strongly scrape off the dirt, thereby further improving the cleaning effect of the scraping plate 46. When there are protrusions on the inner wall of the through hole 32 that are difficult to scrape off, during the process of scraping the dirt, the scraping plate 46 will adaptively push the push rod 45 to contract into the storage box 43, pass through from this protrusion, and compress the support spring 44. After the scraping plate 46 passes, the compressed support spring 44 will push the push rod 45 to extend out of the storage box 43 again, so that the scraping plate 46 contacts the side wall of the through hole 32 again, thus preventing the scraping plate 46 from scratching the inner wall of the through hole 32 and damaging itself, ensuring the normal operation of the device. Embodiment 2

[0029] The difference from the above embodiment is that the movable clamping plate 51 is slidably installed on the sliding rod 18, the fixed sleeve 52 is fixedly connected to the movable clamping plate 51, a plurality of limiting plates 53 are uniformly arranged in a circular shape on the outer side of the fixed sleeve 52, the limiting plates 53 are fixedly connected to the movable clamping plate 51, and there is a gap between the limiting plates 53 and the fixed sleeve 52. Slide rails 511 are fixedly connected to the four corners of the movable clamping plate 51.

[0030] Among them, the gap between the limiting plate 53 and the fixed sleeve 52 allows the cylindrical pressing block 54 to pass through.

[0031] The difference from the above embodiment is that the inside of the cylindrical pressing block 54 is hollow, the cylindrical pressing block 54 is slidably installed on the fixed sleeve 52, a plurality of limiting grooves 541 are formed on the outer side of the cylindrical pressing block 54, the limiting plates 53 are slidably installed in the limiting grooves 541, an installation seat 542 is also fixedly connected to the outer side of the cylindrical pressing block 54, the installation seat 542 corresponds to the slide rail 511, a pressing spring 55 is arranged in the fixed sleeve 52, and the two ends of the pressing spring 55 are respectively fixedly connected to the side wall of the movable clamping plate 51 and the inner wall of the cylindrical pressing block 54. The driving rod 56 is a threaded rod, one end of the driving rod 56 is rotatably connected to the cylindrical pressing 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, and a turntable 57 is fixedly connected to the extending end of the driving rod 56.

[0032] Among them, when the movable clamping plate 51 needs to clamp the plate 3, by rotating the driving rod 56 forward, the driving rod 56 pushes the cylindrical pressing block 54 under the cooperation of the thread, so that the movable clamping plate 51 moves towards the plate 3. At this time, the pressing 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 column 16. After the movable clamping plate 51 pushes several plates 3 together, the movable clamping plate 51 stops moving. Then continue to rotate the driving rod 56, so that the cylindrical pressing block 54 moves towards the fixed clamping plate 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 clamping plate 51, stop rotating the driving rod 56. At this time, the compressed support spring 44 exerts pressure on the movable clamping plate 51, so that several plates 3 are stacked more closely together. When it is necessary to release the plate 3 clamped by the movable clamping plate 51, rotate the driving rod 56 reversely through the turntable 57, so that the driving rod 56 pulls the cylindrical pressing block 54 to move towards the support column 16 under the cooperation of the thread. After the cylindrical pressing block 54 moves from the end of the fixed sleeve 52 close to the movable clamping plate 51 to the other end of the fixed sleeve 52, the compressed pressing spring 55 restores its deformation, and the cylindrical pressing block 54 pulls the movable clamping plate 51 away from the plate 3 to release the clamped plate 3. Through the cooperation of the limiting plate 53 and the limiting groove 541, the cylindrical pressing block 54 can move linearly on the fixed sleeve 52.

[0033] The difference from the above embodiment is that the clamping assembly 5 further includes a pressure rod 58. One end of the pressure rod 58 is rotatably connected to the mounting seat 542, and the other end of the pressure rod 58 is rotatably connected with a pressure plate 59. The pressure plate 59 is rotatably mounted on the slide rail 511.

[0034] Among them, when the cylindrical pressing block 54 is located at the end of the fixed sleeve 52 close to the support column 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 cylindrical pressing block 54 moves towards the end of the fixed sleeve 52 close to the movable clamping plate 51, the pressure rod 58 pushes the pressure plate 59 to move towards the other end of the slide rail 511, and applies pressure to the corners of the movable clamping plate 51 through the pressure plate 59. When the movable clamping plate 51 clamps the plate 3, through the cooperation of the cylindrical pressing block 54, the pressure rod 58 and the pressure plate 59, the movable clamping plate 51 can apply pressure to the plate 3 evenly, ensuring that several plates 3 can be stacked closely together.

[0035] The present invention also provides an assembly structure, which uses a stainless-steel heat exchange plate for concentrate drying. The specific steps are as follows: First, cold and hot media are respectively introduced into the channels between several plates 3 through the corresponding through-holes 32 from the cold medium inlet 14 and the hot medium inlet 12, so that the two media exchange heat. Then, the two media are respectively discharged from the cold medium outlet 15 and the hot medium outlet 13. During the heat exchange process, the cleaning component 4 in the through-hole 32 drives the scraper 46 through the turbine 42 to scrape 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 driving rod 56 of the clamping component 5 is rotated, so that the driving rod 56 drives the movable clamping plate 51 through the cylindrical pressing block 54 to quickly loosen or clamp the plate 3.

[0036] Working principle: When in use, the hot medium and the cold medium respectively enter the corresponding through-holes 32 on the plate 3 through the hot medium inlet 12 and the cold medium inlet 14. Subsequently, the hot medium and the cold medium flow into the channels formed between several plates 3 through the through-holes 32. Then, the hot medium is discharged from the hot medium outlet 13, while the cold medium is discharged from the cold medium outlet 15. During this process, the cold medium and the hot medium complete heat exchange. At the same time, the impurities carried in 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. During 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 a thrust to the turbine 42, so that the turbine 42 moves in the same direction as the medium along 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 will be reduced, and the elastic force of the compressed return spring 47 is greater than the thrust of the medium at this time. As a result, the return spring 47 restores its deformation and pushes the turbine 42 to move back to its original position. After the spring restores its deformation, the flowing medium again pushes the turbine 42 to move and compresses the return spring 47. By repeating the above process, while the turbine 42 drives the scraper 46 to rotate, it will also drive 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. When it is necessary to maintain the plate 3, the driving rod 56 is rotated in the reverse direction by the turntable 57, so that the driving rod 56 pulls the cylindrical pressing block 54 to move towards the support column 16 under the cooperation of the thread. After the cylindrical pressing block 54 moves from one end of the fixed sleeve 52 close to the movable clamping plate 51 to the other end of the fixed sleeve 52, the compressed pressing spring 55 restores its deformation. Then the cylindrical pressing block 54 pulls the movable clamping plate 51 away from the plate 3, releasing the clamped plate 3, enabling the staff to remove the plate 3 from the main body 1. After the maintenance is completed, the staff places the plate 3 on the main body 1 again. After the plate 3 is placed, by rotating the driving rod 56 in the forward direction, the driving rod 56 pushes the cylindrical pressing block 54 under the cooperation of the thread, causing the movable clamping plate 51 to move towards the plate 3. At this time, the pressing spring 55 in the fixed sleeve 52 pushes the cylindrical pressing block 54 to one end of the fixed sleeve 52 close to the support column 16. After the movable clamping plate 51 pushes several plates 3 to stack together, the movable clamping plate 51 stops moving. Then continue to rotate the driving rod 56, making the cylindrical pressing block 54 move towards the fixed clamping plate and compressing the pressing spring 55. After the cylindrical pressing block 54 moves to one end of the fixed sleeve 52 close to the movable clamping plate 51, stop rotating the driving rod 56. At this time, the compressed support spring 44 applies pressure to the movable clamping plate 51, so that several plates 3 stack together more tightly, forming a channel for the medium to flow through, enabling the device to be put into use again. Among them, when the cylindrical pressing block 54 is located at one end of the fixed sleeve 52 close to the support column 16, the pressing rod 58 pulls the pressing plate 59 to one end of the slide rail 511 close to the fixed sleeve 52. When the cylindrical pressing block 54 moves towards one end of the fixed sleeve 52 close to the movable clamping plate 51, the pressing rod 58 pushes the pressing plate 59 to move towards the other end of the slide rail 511, and applies pressure to the corners of the movable clamping plate 51 through the pressing plate 59. When the movable clamping plate 51 clamps the plate 3, through the cooperation of the cylindrical pressing block 54 with the pressing rod 58 and the pressing plate 59, the movable clamping plate 51 can evenly apply pressure to the plate 3, ensuring that several plates 3 can stack together tightly.
