The shells include two upper shells 201, two middle shells 202 and two lower shells 203 arranged from top to bottom. The heat exchange core includes multiple liquid outlet plates 204, multiple heat exchange plates 205 and multiple liquid inlet plates 206 arranged from top to bottom. Both ends of the upper shell 201, the lower shell 203, the liquid outlet plate 204 and the liquid inlet plate 206 are provided with through holes 207 for gas and liquid circulation. 06 are respectively provided with a connecting cavity 208 at both ends thereof, and a heat exchange cavity 210 is respectively provided at both ends thereof. The liquid outlet plate 204 and the liquid inlet plate 206 at one end thereof corresponding to the heat exchange plate 205 are respectively provided with a first through groove 209, so that the connecting cavity 208 is connected to the heat exchange cavity 210 through the first through groove 209. The connecting cavities 208 are not connected to the two adjacent through holes 207 at the same time. The two adjacent connecting cavities 208 are staggered in the horizontal direction, and the two adjacent connecting cavities 208 are symmetrical in the vertical direction. A first sealing strip 215 is provided between the two adjacent liquid outlet plates 204, between the liquid outlet plate 204 and the upper shell 201, between the two adjacent liquid inlet plates 206, and between the liquid inlet plate 206 and the lower shell 203. A second sealing strip 216 is provided between the two adjacent heat exchange plates 205 and between the heat exchange plate 205 and the middle shell 202. A third sealing strip 217 is provided on the surface of the liquid outlet plate 204 and the liquid inlet plate 206, respectively, and the third sealing strip 217 is tightly fitted with the upper shell 201 and the lower shell 203, so that gas and liquid do not leak when flowing inside the through holes 207, the connecting cavities 208, the first through grooves 209 and the heat exchange cavity 210. A groove 218 is provided on the surface of the middle shell 202.

[0019] When the above structure is in use, when the gas and liquid substances enter the inner wall of the communication cavity 208 through the through hole 207, the normal state is that the gas and liquid substances enter the inner wall of the heat exchange cavity 210 through the first through groove 209 to perform heat exchange operation.

[0020] A plurality of dividing strips 211 are fixedly installed on the inner wall of the upper shell 201 and the lower shell 203 corresponding to the first through groove 209, and the plurality of dividing strips 211 are respectively located at the two ends of the liquid outlet plate 204 and the liquid inlet plate 206, and a baffle rod 212 is movably connected between the two adjacent dividing strips 211. The baffle rod 212 is movably connected to the middle of the upper shell 201 and the lower shell 203, and the baffle rod 212 is movably connected between the liquid outlet plate 204 and the heat exchange plate 205 and the liquid inlet plate 206 and the heat exchange plate 205. A second through groove 213 is opened on the surface of the baffle rod 212 corresponding to the first through groove 209, so that when the baffle rod 212 drives the second through groove 213 to coincide with the first through groove 209, the communicating cavity 208 and the first through groove 209 at the same end are connected. 9 and the heat exchange cavity 210 are connected. When the baffle rod 212 drives the second through groove 213 to intersect with the first through groove 209, the heat exchange cavity 210 is not connected with the first through groove 209 and the connecting cavity 208. At this time, the middle shell 202 is pushed horizontally to drive the heat exchange plate 205 to separate from the heat exchange module. The width of the first through groove 209 is equal to the width of the second through groove 213. A sealing layer is provided on the surface of the baffle rod 212 to form a dynamic seal between the baffle rod 212 and the partition bar 211, the liquid outlet plate 204, the heat exchange plate 205 and the liquid inlet plate 206. The baffle rod 212 movably penetrates and extends to the outside of the upper shell 201 and the lower shell 203. The end of the baffle rod 212 away from the position of the upper shell 201 and the lower shell 203 is fixedly installed with a connecting plate 214.

[0021] When the above structure is in use, the baffle rod 212 drives the second through groove 213 to intersect with the first through groove 209, and makes the connecting cavity 208 disconnected from the heat exchange cavity 210 through the first through groove 209. At this time, the middle shell 202 can be taken out and replaced with the heat exchange plate 205. Conversely, when the cleaned middle shell 202 needs to be reinstalled, it is only necessary to align the middle shell 202 with the position between the upper shell 201 and the lower shell 203 to be installed, and insert the middle shell 202 into the target position, that is, align it with the upper shell 201 and the lower shell 203. Then, push the connecting plate 214 so that the connecting plate 214 drives the second through groove 213 to overlap with the first through groove 209 through the baffle rod 212. The heat exchange plate 205 can be cleaned and replaced without stopping the machine, thereby achieving the purpose of facilitating online disassembly and cleaning.

[0022] The outer shell assembly includes a front end plate 101 and a rear end plate 102, the top and bottom of one end of the front end plate 101 are respectively fixedly installed with a guide rod 103 and a supporting bottom rod 105, the guide rod 103 movably passes through the top of the rear end plate 102, and the guide rod 103 and the supporting bottom rod 105 are fixedly installed with a rear vertical rod 104 at one end away from the front end plate 101, and the bottom of the guide rod 103 is in an I-shaped structure. An I-shaped groove is provided on the top of the upper shell 201 corresponding to the guide rod 103, so that the upper shell 201 can be stacked in order in the outer shell assembly, and the lower shell 203 can be movably overlapped on the top of the supporting bottom rod 105, and a connecting pipe 106 is fixedly embedded in the middle of the front end plate 101 and the rear end plate 102 corresponding to the through hole 207. Positioning rods 107 are respectively movably passed through both ends of the front end plate 101 and the rear end plate 102, so that the heat exchange module can be neatly stacked in the outer shell assembly.

[0023] When the above structure is in use, when assembling the device, the front end plate 101, the guide rod 103 and the supporting bottom rod 105 are first assembled so that the rear end plate 102 can move along the direction of the guide rod 103. At this time, multiple heat exchange modules are placed between the front end plate 101 and the rear end plate 102 in sequence, and the I-shaped groove on the top of the upper shell 201 is movably plugged into the I-shaped structure at the bottom of the guide rod 103, so that multiple heat exchange modules are stacked in order. Then, the rear end plate 102 is put on the surface of the guide rod 103, and the front end plate 101, the heat exchange module and the rear end plate 102 are locked by multiple positioning rods 107, thereby realizing the installation of the device.

[0024] The cam 308 is a kind of cam which is used to move the cam 308 to the support frame 310, and the cam 308 is a kind of cam which moves the cam 308 to the support frame 310. The cam 308 is a kind of cam which moves the cam 308 to the support frame 310, and the cam 308 is a kind of cam which moves the cam 308 to the support frame 310. A return spring 306 is fixedly installed at one end corresponding to the position of the driving rod 305, and an arc-shaped driving plate 310 is fixedly installed at the middle part of the connecting plate 214 corresponding to the position of the driving arm 307. A hole is opened in the middle part of the connecting plate 214 corresponding to the position of the hinged arm 303, and a first guide rod 308 is fixedly installed at one end of the driving arm 307, and the first guide rod 308 is movable through and extends to the two ends of the movable plate 301, so that the first guide rod 308 cooperates with the movable plate 301 to guide the movement of the driving arm 307. The width of the hinged arm 303 is smaller than the width of the hole in the middle of the connecting plate 214. The driving arm 307 and the arc-shaped driving plate 310 are both arc-shaped structures, so that when the driving arm 307 is located on the inner wall of the arc-shaped driving plate 310, when the driving arm 307 moves outward, the arc-shaped driving plate 310 cooperates with the connecting plate 214 to drive the baffle rod 212 to move.

[0025] When the above structure is in use, the pull plate 309 is pulled in the direction of the second guide rod 311, and the pull plate 309 drives the movable plate 301 to move on the surface of the second guide rod 311 through the driving rod 305 until the driving arm 307 moves to the connection plate 214 position of the target heat exchange module, and the driving arm 307 is located on the inner wall of the arc-shaped driving plate 310. At this time, the pull plate 309 is pulled in the direction of the driving rod 305, and the pull plate 309 drives the hinge seat 304 to be hinged through the driving rod 305. At the same time, the hinge seat 304 cooperates with the return spring 306 to drive the driving arm 307 to move in the direction of the driving rod 305. The hinge arm 303 enters the connection plate 214 position. At the same time, the driving arm 307 in the hole of the plate 214 drives the arc driving plate 310 to move toward one end of the pulling plate 309, that is, the driving arm 307 will preferentially drive the flow blocking rod 212 to move through the arc driving plate 310 in cooperation with the connecting plate 214, and make the flow blocking rod 212 drive the second through groove 213 and the first through groove 209 to stagger and block the fluid channel. Then, under the action of continuous pulling of the pulling plate 309, the hinged arm 303 will pass through the hole of the connecting plate 214 and contact the middle shell 202, thereby pushing the middle shell 202 out of the position between the upper shell 201 and the lower shell 203. At this time, the middle shell 202 carrying the heat exchange plate 205 can be taken out for replacement through the groove 218.

[0026] Working principle: When in use, the invention assembles the front end plate 101, the guide rod 103 and the supporting bottom rod 105 first, so that the rear end plate 102 can move along the direction of the guide rod 103. At this time, multiple heat exchange modules are placed between the front end plate 101 and the rear end plate 102 in turn, and the I-shaped groove on the top of the upper shell 201 is movably plugged into the I-shaped structure at the bottom of the guide rod 103, so that multiple heat exchange modules are stacked in order. Then, the rear end plate 102 is put on the surface of the guide rod 103, and the front end plate 101, the heat exchange module and the rear end plate 102 are locked by multiple positioning rods 107, thereby realizing the installation of the present device.

[0027] When the heat exchange chamber 210 in a heat exchange module is blocked after long-term use, the pull plate 309 is pulled along the direction of the second guide rod 311, and the pull plate 309 drives the movable plate 301 to move on the surface of the second guide rod 311 through the driving rod 305 until the driving arm 307 moves to the connecting plate 214 position of the target heat exchange module, and the driving arm 307 is located on the inner wall of the arc-shaped driving plate 310. At this time, the pull plate 309 is pulled along the direction of the driving rod 305, and the pull plate 309 drives the hinge seat 304 to be hinged through the driving rod 305. At the same time, the hinge seat 304 cooperates with the reset spring 306 to drive the driving arm 307 to move along the direction of the driving rod 305.

[0028] During the above process, when the articulated arm 303 enters the hole of the connecting plate 214, the driving arm 307 drives the arc-shaped driving plate 310 to move toward one end of the pulling plate 309, that is, the driving arm 307 will preferentially drive the flow-blocking rod 212 to move through the arc-shaped driving plate 310 in cooperation with the connecting plate 214, and make the flow-blocking rod 212 drive the second through groove 213 and the first through groove 209 to intersect and block the fluid channel. Then, under the action of the continuous pulling of the pulling plate 309, the articulated arm 303 will pass through the hole of the connecting plate 214 and contact the middle shell 202, thereby pushing the middle shell 202 out of the position between the upper shell 201 and the lower shell 203. At this time, the middle shell 202 carrying the heat exchange plate 205 can be taken out for replacement through the groove 218.

[0029] When the gas and liquid enter the inner wall of the communication cavity 208 through the through hole 207, the normal state is that the gas and liquid enter the inner wall of the heat exchange cavity 210 through the first through groove 209 to perform heat exchange operation. When disassembly is required, as the baffle rod 212 moves, the baffle rod 212 drives the second through groove 213 to intersect with the first through groove 209, and the communication cavity 208 is disconnected from the heat exchange cavity 210 through the first through groove 209. At this time, the middle shell 202 can be taken out to replace the heat exchange plate 205. On the contrary, when disassembly is required, the baffle rod 212 drives the second through groove 213 to intersect with the first through groove 209, and the heat exchange plate 205 can be taken out to replace the heat exchange plate 205. When reinstalling the cleaned middle shell 202, it is only necessary to align the middle shell 202 with the position between the upper shell 201 and the lower shell 203 to be installed, and insert the middle shell 202 into the target position, that is, align it with the upper shell 201 and the lower shell 203. Then, push the connecting plate 214 so that the connecting plate 214 drives the second through groove 213 to coincide with the first through groove 209 through the baffle rod 212. The heat exchange plate 205 can be cleaned and replaced without stopping the machine, thereby achieving the purpose of facilitating online disassembly and cleaning.
