DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the specification of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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 creative work are within the scope of protection of the present invention.

[0020] Please see attached Figure 1 -Attached Fig. 9 An embodiment of the present invention provides a plate heat exchanger with adjustable partition spacing, including a mounting frame 1, a partition spacing moving mechanism 2 is arranged inside the mounting frame 1, a locking mechanism 3 is arranged on the inner side of the mounting frame 1, the locking mechanism 3 is used to lock and stabilize the partition spacing moving mechanism 2, a connecting mechanism 4 is arranged on the side of the partition spacing moving mechanism 2 away from the locking mechanism 3, after rotating the locking mechanism 3, the distance between each plate in the partition spacing moving mechanism 2 can be adjusted, and at the same time, the connecting mechanism 4 can be used to realize the connection between the exchanger and the external pipeline.

[0021] The partition spacing moving mechanism 2 includes four mounting rods 201, which can provide mounting positions. The outer ends of the four mounting rods 201 are respectively fixedly connected to the four inner corners of the mounting frame 1. A plurality of baffles 202 are slidably connected between the outer parts of the four mounting rods 201. The four inner corners of the baffles 202 are fixedly connected to a base 203. The base 203 provides a mounting position. The inner part of the base 203 is slidably connected to a limiting ring 204, which plays a limiting role. The outer side of the limiting ring 204 is fixedly connected to a movable tube 205, which can slide inside the base 203 so as to adjust the distance between the plurality of baffles 202. A return spring is fixedly connected between the inside of the movable tube 205 and the inside of the base 203. 206, the action of the return spring 206 can make the movable tube 205 move out of the interior of the base 203, so that the spacing between the multiple baffles 202 can be expanded at the same time, and the outer walls of several bases 203 and movable tubes 205 are provided with water holes 207, and the water holes 207 can flow in and out of water, and the bases 203 and movable tubes 205 with water holes 207 and the bases 203 and movable tubes 205 without water holes 207 are staggered. Therefore, after the fluid enters the interior of the base 203 and the movable tube 205 through the connecting mechanism 4 and flows out, the base 203 and movable tube 205 with water holes 207 will flow in or out of the fluid. Therefore, in the space formed by the heat-resistant flexible sleeve 210 and the baffle 202, there will be intervals of fluid. The body can be separated by cold fluid and hot fluid, a sliding plate 208 is slidably connected between the outsides of the four mounting rods 201, and the sliding plate 208 can drive the baffle 202 to move, a fixed plate 209 is fixedly connected between the ends of the four mounting rods 201 away from the mounting frame 1, and the fixed plate 209 can be combined with the baffle 202 away from the mounting frame 1 to form a space, a heat-resistant flexible sleeve 210 is fixedly connected between the multiple baffles 202, and the heat-resistant flexible sleeve 210 is flexible, so it can be folded and unfolded, a threaded rod 211 is rotatably connected between the upper and lower ends of the mounting frame 1 and the fixed plate 209, a mounting frame 212 is fixedly connected to the inner side of the mounting frame 1, and the upper and lower ends of the sliding plate 208 are respectively threadedly connected to the outsides of the two threaded rods 211 The movable tube 205 is slidably connected to one side of the base 203, and one side of the baffle 202 close to the locking mechanism 3 is fixedly connected to the side of the sliding plate 208 away from the locking mechanism 3. When adjusting the spacing of the baffles 202, the rotating locking mechanism 3 drives the threaded rod 211 to rotate through the belt. After the threaded rod 211 rotates, it can drive the sliding plate 208 to move in the direction of the fixed plate 209. After the sliding plate 208 moves, it drives the baffle 202 to move in the direction of the fixed plate 209, thereby driving the base 203 to compress the reset spring 206. At this time, the movable tube 205 moves toward the inside of the base 203, thereby driving the limit ring 204 to move toward the inside of the base 203. At this time, the distance between the baffles 202 can be shortened.If the distance between the baffles 202 is increased, the locking mechanism 3 can be rotated in the reverse direction, so that the sliding plate 208 can be driven to move away from the fixed plate 209, and then the baffle 202 can be driven to move away from the fixed plate 209. At this time, the return spring 206 uses its own reaction force to drive the movable tube 205 to move toward the outside of the base 203, so that the spacing between the multiple baffles 202 can be equal.

[0022] The locking mechanism 3 includes a rotating shaft 301, which provides an installation position and can drive the structure thereon to rotate. The side of the rotating shaft 301 close to the connecting mechanism 4 is rotatably connected to the outside of the mounting frame 212. The side of the rotating shaft 301 close to the mounting frame 212 is fixedly connected with a card gear 302. The side of the card gear 302 away from the mounting frame 212 is rotatably connected with a rotating mounting disk 303. The rotating mounting disk 303 can provide an installation position. The outside of the rotating mounting disk 303 is fixedly connected with a mounting shell 306. The mounting shell 306 can provide an installation shell. The inside of the mounting shell 306 is rotatably connected with a rotating rod 304. The side of the rotating rod 304 away from the mounting frame 212 is fixedly connected with a turning handle 305. The outer side of the rod 304 is fixedly connected with a claw 307 on the side close to the mounting bracket 212, and the turning handle 305 can drive the rotating rod 304 to rotate. The side of the rotating rod 304 close to the connecting mechanism 4 is rotatably connected to the middle part of the mounting bracket 212. The middle part of the rotating rod 304 is sleeved with a torsion spring 308, which can drive the rotating rod 304 to reset. One end of the torsion spring 308 is fixedly connected to the outer side of the rotating rod 304, and the other end of the torsion spring 308 is fixedly connected to the inside of the mounting shell 306. The side of the rotating shaft 301 away from the mounting bracket 212 is fixedly connected with a rotating handle 309, and the rotating handle 309 can drive the rotating shaft 301 to rotate. The claw 307 is engaged with the outer side of the card gear 302, and the rotating shaft 301 is connected to the threaded rod 2 One end of the four mounting rods 201 is connected by a belt, and the sides of the four mounting rods 201 away from the mounting frame 1 are detachably connected to the four corners of the fixing plate 209. When the locking mechanism 3 is rotated, the rotating handle 309 is rotated first. After the rotating handle 309 is rotated, the rotating shaft 301 is driven to rotate. After the rotating shaft 301 is rotated, the threaded rod 211 can be driven to rotate through the belt. The rotation of the rotating shaft 301 can drive the card gear 302 to rotate. At this time, when the side of the claw 307 close to the rotating shaft 301 passes through the inclined surface on the card gear 302, the claw 307 will rotate to the side away from the rotating shaft 301, and then the rotating rod 304 can be driven to rotate through the claw 307, and then the compression torsion spring 308 can be twisted. When the claw 307 passes over the inclined surface on the card gear 302, the claw 307 will rotate to the side away from the rotating shaft 301. When the inclined surface of the card gear 302 reaches the straight surface of the teeth of the card gear 302, the reaction force of the torsion spring 308 drives the rotating rod 304 to rotate in the direction of the card gear 302, and then the claw 307 can be driven to rotate in the direction of the card gear 302, and then the claw 307 can be used to press against the straight surface of the teeth of the card gear 302 to complete the engagement of the claw 307 and the card gear 302, preventing the card gear 302 from reversing, thereby preventing the rotating shaft 301 from reversing. If the rotating shaft 301 is reversed, the turning handle 305 is turned downward, which can drive the rotating rod 304 to rotate downward and then drive the claw 307 to rotate upward, releasing the engagement between the claw 307 and the card gear 302, and the rotating handle 309 can be reversed at this time.

[0023] The connecting mechanism 4 includes a liquid passage 401, which can play the role of installing water. The side of the liquid passage 401 close to the mounting frame 212 is fixedly connected to the side of the fixing plate 209 away from the mounting frame 212. The outside of the liquid passage 401 is fixedly connected with a fixing ring 402, and the fixing ring 402 can provide an installation position. The side of the fixing ring 402 away from the fixing plate 209 is fixedly connected with a tension spring 403, and the side of the tension spring 403 away from the fixing plate 209 is fixedly connected with a sliding ring 404, and the sliding ring 404 can provide an installation position. The outside of the sliding ring 404 is rotatably connected with a plurality of locking arms 405, and the locking arms 405 are close to the fixing plate 209. A spring piece 406 is fixedly connected to the inner side of the end, a sealing head 408 is arranged on the side of the liquid passage tube 401 away from the fixed plate 209, and the sealing head 408 can be installed on the side of the liquid passage tube 401 away from the partition spacing moving mechanism 2, and the sealing head 408 is fixedly connected to the side away from the fixed plate 209. A connecting pipe 407 is fixedly connected to the outside of the sealing head 408, and the clamping ring 409 is clamped with a plurality of clamping arms 405. The tension spring 403 is sleeved on the outside of the liquid passage tube 401, and the sliding ring 404 is slidably connected to the outside of the liquid passage tube 401. A sealing sleeve is fixedly connected to the inner side of the sealing head 408, and the spring piece 406 is fixed on the side away from the clamping arm 405. When connecting the pipeline to the outside of the sliding ring 404, first move the connecting pipe 407 toward the direction of the liquid pipe 401. At this time, the sealing head 408 can be engaged with the end of the liquid pipe 401 away from the fixed plate 209. At this time, move the sliding ring 404 toward the connecting pipe 407 to stretch the tension spring 403. The sliding ring 404 drives the locking arm 405 to move toward the connecting pipe 407. At this time, since the head of the locking arm 405 is a curved surface, and the direction of the locking ring 409 close to the sliding ring 404 is a curved surface, the locking arm 405 can push the head of the locking arm 405 outward after contacting the locking ring 409. The locking arm 405 is in a state of being moved toward the sliding ring 404 by the spring 406. At this time, the tail of the locking arm 405 compresses the spring 406. When the locking arm 405 is stuck on the side of the locking ring 409 away from the sliding ring 404, the head of the locking arm 405 is driven to rotate toward the middle under the action of the spring 406, so that the locking arm 405 and the locking ring 409 can be locked. At this time, under the pulling force of the tension spring 403, the sliding ring 404 can be given a force toward the fixed plate 209, so that the locking arm 405 can tighten the locking ring 409, and then the sealing head 408 can be tightly squeezed on the side of the liquid passage 401 away from the fixed plate 209.

[0024] Working principle: when adjusting the spacing between the baffles 202, the rotating locking mechanism 3 drives the threaded rod 211 to rotate through the belt. After the threaded rod 211 rotates, it can drive the sliding plate 208 to move in the direction of the fixed plate 209. After the sliding plate 208 moves, it drives the baffle 202 to move in the direction of the fixed plate 209, thereby driving the base 203 to compress the return spring 206. At this time, the movable tube 205 moves toward the inside of the base 203, thereby driving the limit ring 204 to move toward the inside of the base 203. At this time, the distance between the baffles 202 can be shortened. If the distance between the baffles 202 is increased, the locking mechanism 3 can be rotated in the opposite direction, thereby driving the sliding plate 208 to move away from the fixed plate 209, and then driving the baffle 202 to move away from the fixed plate 209. At this time, the return spring 206 uses its own reaction force to drive the movable tube 205 to move toward the outside of the base 203, so that the distances between multiple baffles 202 can be equal. When the locking mechanism 3 is rotated, the rotating handle 309 is rotated first. After the rotating handle 309 is rotated, the rotating shaft 301 is driven to rotate. After the rotating shaft 301 is rotated, the threaded rod 211 can be driven to rotate through the belt. The rotation of the rotating shaft 301 can drive the card gear 302 to rotate. At this time, when the side of the claw 307 close to the rotating shaft 301 passes through the inclined surface on the card gear 302, the claw 307 will rotate to the side away from the rotating shaft 301, and then the rotating rod 304 can be driven to rotate through the claw 307, and then the compression torsion spring 308 can be twisted. When the claw 307 passes over the inclined surface of the card gear 302 and reaches the straight surface of the card gear 302 teeth, Under the reaction force of the torsion spring 308, the rotating rod 304 is driven to rotate in the direction of the card gear 302, and then the claw 307 can be driven to rotate in the direction of the card gear 302, and then the claw 307 can be used to abut against the straight surface of the card gear 302 teeth to complete the engagement of the claw 307 and the card gear 302, preventing the card gear 302 from reversing, thereby preventing the rotating shaft 301 from reversing. If the rotating shaft 301 is reversed, the turning handle 305 is turned downward, so that the rotating rod 304 can be driven to rotate downward, and then the claw 307 can be driven to rotate upward, releasing the engagement of the claw 307 and the card gear 302, and at this time, the rotating handle 309 can be reversed; When connecting the pipelines, first move the connecting pipe 407 toward the direction of the liquid passage pipe 401. At this time, the sealing head 408 can be engaged with the end of the liquid passage pipe 401 away from the fixed plate 209. At this time, move the sliding ring 404 toward the connecting pipe 407 to stretch the tension spring 403. The sliding ring 404 drives the locking arm 405 to move toward the direction of the connecting pipe 407. At this time, since the head of the locking arm 405 is a curved surface, and the direction of the locking ring 409 close to the sliding ring 404 is a curved surface, the locking arm 405 can push the head of the locking arm 405 outward after contacting the locking ring 409. At this time, the locking arm 405 The tail of the arm 405 moves toward the sliding ring 404. At this time, the tail of the locking arm 405 compresses the spring piece 406. When the locking arm 405 is locked in the side of the locking ring 409 away from the sliding ring 404, the head of the locking arm 405 is driven to rotate toward the middle under the action of the spring piece 406, so that the locking arm 405 and the locking ring 409 can be locked. At this time, under the pulling force of the tension spring 403, the sliding ring 404 can be given a force toward the fixed plate 209, so that the locking arm 405 can tighten the locking ring 409, and then the sealing head 408 can be tightly squeezed on the side of the liquid tube 401 away from the fixed plate 209.
