However, frequent disassembly and assembly not only increases maintenance costs and labor intensity, but may also cause the interlayer plates to be poorly sealed after multiple installations.

[0027] The technical solutions provided by various embodiments of the present invention are described in detail below in conjunction with the accompanying drawings.

[0028] See also Figure 1-Figure 9The present invention discloses an energy-saving chemical-specific heat exchange device, comprising a front panel 100 and a rear panel 101, a support rod assembly 102 is connected between the front panel 100 and the rear panel 101, a partition plate assembly is connected to the support rod assembly 102, the partition plate assembly is composed of a plurality of partition plate bodies and a sealing assembly, a plurality of first water chambers and a second water chamber are arranged between the plurality of partition plate bodies and the sealing assembly, the first water chambers and the second water chambers are arranged alternately, and a plurality of partition plate bodies and the sealing assembly are provided with a water inlet channel a208, a water inlet channel b209, a water outlet channel b208, a water outlet ... The water inlet a208 and the water outlet a210 are connected to the first water cavity, the water inlet b209 and the water outlet b211 are connected to the second water cavity, and the front panel 100 is provided with a water inlet a104, a water inlet b106, a water outlet a105 and a water outlet b107, and the water inlet a104, the water inlet b106, the water outlet a105 and the water outlet b107 are sealed and connected to the water inlet a208, the water inlet b209, the water outlet a210 and the water outlet b211 respectively. The support rod assembly 102 is connected with a locking plate 300 for pressing the interlayer plate group, and a locking member 103 is connected between the locking plate 300 and the front panel 100. A filter assembly is provided in the water inlet channel a208 and the water inlet channel b209, wherein the interlayer plate group includes a first interlayer plate 200, a second interlayer plate 201, a third interlayer plate 203, a fourth interlayer plate 204 and a fifth interlayer plate 205, and the sealing assembly includes two first sealing strips 206 and two second sealing strips 207, and the two first sealing strips 206 are respectively located on the second interlayer plate 201 and the third barrier plate 203, and between the fourth barrier plate 204 and the fifth barrier plate 205. The two second sealing strips 207 are respectively located between the first barrier plate 200 and the second barrier plate 201 and between the third barrier plate 203 and the fourth barrier plate 204. A first water cavity is formed between the first barrier plate 200 and the second barrier plate 201 and between the third barrier plate 203 and the fourth barrier plate 204. A second water cavity is formed between the second barrier plate 201 and the third barrier plate 203 and between the fourth barrier plate 204 and the fifth barrier plate 205.

[0029] By adopting the scheme of the present invention, during operation, the hot fluid and the cold fluid enter the water inlet channel a208 and the water inlet channel b209 respectively through the water inlet a104 and the water inlet b106, and then the hot fluid and the cold fluid enter the corresponding first water chamber and the second water chamber respectively. Therefore, the hot and cold fluids flow in their respective water chambers and exchange heat. The locking plate 300 is used to ensure that the interlayer plate group is tightly fixed to prevent leakage. Since a filter assembly is arranged in the water inlet channel a208 and the water inlet channel b209, impurities in the fluid can be removed and scale generated by the fluid can be prevented from entering the first water chamber and the second water chamber, which simplifies the difficulty of maintenance work and ensures the long-term stable operation of the equipment.

[0030] In a preferred embodiment, the filter drive assembly includes two filter covers 301 installed on a locking plate 300, each filter cover 301 is provided with a leakage groove 311, and the two filter covers 301 are snugly inserted into the water inlet channel a208 and the water inlet channel b209. The leakage groove 311 located in the water inlet channel a208 corresponds to the position of the first water cavity, and the leakage groove 311 located in the water inlet channel b209 corresponds to the position of the second water cavity.

[0031] With such a scheme, the filter cover 301 in the filter assembly is installed on the locking plate 300, and each filter cover 301 is provided with a leakage groove 311. The two filter covers 301 are snugly inserted into the water inlet channel a208 and the water inlet channel b209. The leakage groove 311 located in the water inlet channel a208 corresponds to the position of the first water cavity, and the leakage groove 311 located in the water inlet channel b209 corresponds to the position of the second water cavity. Therefore, the sealing effect can be further improved while realizing the filtering function.

[0032] In a preferred embodiment, two independent reflux chambers 313 are provided in the locking plate 300, and the two reflux chambers 313 are respectively connected to the water inlet channel a208 and the water outlet channel a210 and the water inlet channel b209 and the water outlet channel b211. A first cleaning component is provided on the locking plate 300, and the first cleaning component is located in the filter cover 301 and is used to push the scale on the leakage groove 311 into the reflux chamber 313. The first cleaning component includes a rotating tube 303 that is sealed and rotatably connected to the locking plate 300, and the rotating tube 303 extends into the filter cover 301. A plurality of connecting rods 306 are connected to the surface of the rotating tube 303, and a spiral sheet 305 is connected to the end of the connecting rod 306 away from the rotating tube 303, and the spiral sheet 305 is in contact with the inner wall of the filter cover 301. The locking plate 300 is provided with a driving part for driving the rotating tube 303 to rotate.

[0033] With this solution, two independent reflux chambers 313 are provided in the locking plate 300, which are connected to the water inlet channel a208 and the water outlet channel a210 and the water inlet channel b209 and the water outlet channel b211 respectively. When the heat exchanger is running, impurities in the fluid will be blocked by the leakage groove 311 on the filter cover 301. As time goes by, these impurities will accumulate on the leakage groove 311 to form scale. At this time, by starting the driving part, the rotating tube 303 is driven to rotate, and the rotation of the rotating tube 303 is transmitted to the screw through the connecting rod 306. The spiral blade 305 makes the spiral blade 305 do circular motion on the inner wall of the filter cover 301. Since the spiral blade 305 fits the inner wall of the filter cover 301, it will scrape off the scale attached to the leakage groove 311 and push it into the reflux chamber 313. Through the built-in first cleaning component, the heat exchange device can automatically clean the scale on the filter cover 301 without manual intervention, thereby reducing the maintenance workload. When maintenance is required, it is only necessary to remove the locking plate 300 without removing the interlayer plate group one by one, thereby greatly reducing the difficulty of maintenance.

[0034] Optionally, the driving unit includes a motor 400 mounted on the locking plate 300, the output end of the motor 400 is connected to the first gear 401, the locking plate 300 is rotatably connected to a rotating shaft 402, the rotating shaft 402 is connected to a second gear 403 meshing with the first gear 401, the rotating shaft 402 is connected to a second sprocket 404, the rotating tube 303 extends through the locking plate 300 and is connected to the first sprocket 304, and a first chain 405 is connected between the first sprocket 304 and the second sprocket 404.

[0035] In a preferred embodiment, a second cleaning component is provided on the locking plate 300 , and the second cleaning component is used to spray a descaling agent into the filter cover 301 .

[0036] Specifically, the second cleaning assembly includes a box body 302 mounted on the locking plate 300, the first sprocket 304 is located in the box body 302, the box body 302 is connected to a fixed pipe assembly 307, the fixed pipe assembly 307 is located inside the rotating tube 303 and is sealed with the rotating tube 303, the locking plate 300 is connected to a support frame 501, the support frame 501 is provided with two symmetrical slide grooves 502, the two symmetrical slide grooves 502 are slidably connected to a moving column 503, the moving column 503 is rotatably connected to the third sprocket 504, and the moving column 501 is connected to the third sprocket 504. 03 is connected with a suction pump 505, a coupling is connected between the suction pump 505 and the third sprocket 504, a box body 500 is installed on the locking plate 300, the input end of the suction pump 505 is connected with the box body 500 through a pipeline, the output end of the suction pump 505 is connected with the fixed pipe assembly 307, a first through hole 308 is provided at the bottom of the fixed pipe assembly 307, a second through hole 312 is provided on the rotating tube 303, a two-way cylinder 506 is installed on the support frame 501, and both ends of the two-way cylinder 506 are respectively connected with two movable columns 503.

[0037] With such a scheme, when the two-way cylinder 506 drives the two movable columns 503 to approach each other, the third sprocket 504 contacts the first chain 405 to rotate, thereby driving the suction pump 505 to operate. Therefore, the suction pump 505 extracts the descaling agent in the box body 500 through the pipeline and discharges it into the fixed pipe assembly 307. The descaling agent is discharged between the fixed pipe assembly 307 and the rotating pipe 303 through the first through hole 308 on the fixed pipe assembly 307, and then discharged into the filter cover 301 through the second through hole 312 on the rotating pipe 303. Part of the descaling agent enters the first water cavity and the second water cavity, thereby achieving a scale cleaning effect on the entire heat exchange device, and the contact between the third sprocket 504 and the first chain 405 can also achieve a tensioning effect.

[0038] In a preferred embodiment, a plurality of levers 309 are connected to the fixed tube assembly 307 , and a plurality of grooves 310 are disposed on the inner wall of the rotating tube 303 .

[0039] With such a solution, the multiple levers 309 on the fixed tube assembly 307 are located in the groove 310 in the rotating tube 303. Since the fixed tube assembly 307 is fixed, when the rotating tube 303 rotates, a vibration effect is generated, which is further transmitted to the spiral sheet 305, causing the spiral sheet 305 to vibrate. The vibration effect helps to loosen the scale attached to the spiral sheet 305 and the filter screen of the leakage groove 311, thereby improving the cleaning efficiency and ensuring the long-term stable operation of the heat exchanger.

[0040] In a preferred embodiment, a stirring assembly is provided in the box body 500, a fourth sprocket 507 is rotatably connected to the box body 500, an input end of the stirring assembly is connected to the fourth sprocket 507, a fifth sprocket 509 is connected to the rotating shaft 402, and a second chain 508 is connected between the fourth sprocket 507 and the fifth sprocket 509.

[0041] With such a solution, when the motor 400 drives the rotating shaft 402 to rotate, the fifth sprocket 509 also rotates through the transmission of the second gear 403, the first gear 401 and the rotating shaft 402, and the fourth sprocket 507 also rotates synchronously. The stirring component will work with the rotation of the fourth sprocket 507 to stir the descaling agent in the box 500, ensuring that the descaling agent is evenly distributed in the box 500, thereby improving the use effect of the descaling agent.

[0042] The present invention improves the utilization rate of heat energy and reduces energy consumption by optimizing the heat exchange path and increasing the heat exchange area, meeting the requirements of energy conservation and emission reduction. By setting filter components in the water inlet channel a208 and the water inlet channel b209, solid particles and other impurities in the fluid are effectively removed to protect the inside of the heat exchanger from pollution. When maintenance is required, only the locking plate 300 needs to be removed, which greatly reduces the difficulty of maintenance. At the same time, the first cleaning component and the second cleaning component are provided in the filter cover 301, which can realize automatic cleaning of scale, further reducing the difficulty of maintenance and improving the efficiency and stability of heat treatment.

[0043] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention.
