Description

Technical Field

[0001] This invention relates to the field of defrosting technology, and in particular to an automatic defrosting evaporation device for quick-freezing tunnels. Background Technology

[0002] In food processing, cold chain logistics and other fields, quick-freezing tunnels are an important type of freezing equipment used to rapidly freeze products to the required low temperatures in order to maintain their quality and extend their shelf life.

[0003] Quick-freezing tunnels typically generate a low-temperature environment through refrigeration modules and use air supply modules to force the circulation of cold air for efficient heat exchange. However, during operation, frost easily forms on the fins of the refrigeration modules. The accumulation of frost significantly reduces heat exchange efficiency, increases energy consumption, and can even affect the normal operation of the equipment. Therefore, regular defrosting is a necessary measure to maintain the efficient operation of quick-freezing tunnels.

[0004] Electric defrosting is a common defrosting method. The heating wire heats the passing air to form hot air, which blows directly onto the fins, causing the frost on the fin surface to melt into water. However, the melted water is difficult to drain and collect in the quick-freezing tunnel. At the same time, the hot air used for defrosting stays in the freezing tunnel for a long time, resulting in a long downtime during defrosting in the freezing tunnel, which affects work efficiency. To address this, we propose an automatic defrosting evaporation device for quick-freezing tunnels. Summary of the Invention

[0056] The technical effects and advantages of this invention are as follows:

[0057] (1) The present invention utilizes the defrosting mechanism and the suction mechanism. The liquid flowing into the liquid receiving hopper will be discharged from the seat body in sequence through the liquid guide groove, bottom groove, connecting pipe and sleeve, avoiding the liquid remaining in the tunnel and frosting again. The outer wall of the connecting pipe and the inner wall of the sleeve are set with an interference fit, so that the liquid in the connecting pipe can be stably discharged through the sleeve, but will not be discharged through the gap between the connecting pipe and the sleeve. The servo motor can drive the rotating rod to rotate, and the rotating rod drives the fan blade to rotate. The rotation of the fan blade can generate suction in the liquid guide groove. This negative pressure can assist the liquid in the connecting pipe and the sleeve to be discharged quickly. At the same time, it can also directly absorb the hot air in the defrosting process and then discharge it through the connecting pipe and the sleeve, thereby reducing the residence time of hot air in the freezing tunnel, thereby reducing the downtime of the freezing tunnel and improving work efficiency.

[0058] (2) This invention utilizes the first sealing mechanism, where four sector-shaped baffles can be combined to form a complete circular disc, thereby sealing the top of the bottom groove. When the defrosting mechanism is not working, the multiple sector-shaped baffles can isolate the liquid guide groove from the bottom groove, preventing cold air in the freezing tunnel from escaping through the connecting pipe and sleeve. However, when the defrosting mechanism is working, the servo motor drives the rotating rod to rotate. Then, with the connection between the second and first fixing bars, the rotating rod's rotation drives the first ring to rotate. Furthermore, with the connection of the connecting plate, the second ring rotates synchronously with the first ring. During this rotation... Due to the mutual limiting of the first connecting rod and the first connecting hole, the sector baffle rotates. Under the action of centrifugal force, the sector baffle moves towards the second ring together with the connecting piece, thereby separating the four sector baffles and connecting the liquid guide tank with the bottom tank. This allows liquid and hot air to enter the bottom tank stably. During the movement of the sector baffle and the connecting piece, the first spring is compressed. After defrosting is completed, the rotating rod stops rotating. At this time, the sector baffle loses the effect of centrifugal force and can move back to its original position under the elastic action of the first spring, so that the four sector baffles combine into a disc for sealing.

[0059] (3) The present invention utilizes the cooperation of the inflation mechanism, the second sealing mechanism and the cleaning mechanism. When the defrosting mechanism is working, the inflation mechanism works simultaneously to inflate the air into the air storage chamber. The second piston block in the connecting plate will also move towards the fixed ring under the action of centrifugal force and compress the second spring. The movement of the second piston block drives the hydraulic oil to move, thereby driving the first piston block to move down. The movement of the first piston block drives the second connecting rod to move down. The movement of the second connecting rod drives the extrusion ring to move down. The movement of the extrusion ring will press down on the stop block, causing the stop block to move down and block the opening of the first connecting hole. Thus, the air in the air storage chamber cannot enter the active chamber through the first connecting hole. Until defrosting is completed, the connecting plate stops rotating. Under the elastic action of the second spring, the second piston block moves in the opposite direction, thereby causing the first piston block and the second connecting rod to rise. At this time, the stop block can rise under the elastic action of the third spring, thereby connecting the first connecting hole with the active chamber, allowing the air in the air storage chamber to be blown into the active chamber for cleaning.

[0060] (4) The present invention utilizes the exhaust mechanism. The air storage chamber is inflated under the operation of the inflation mechanism. At this time, the piston plate descends and drives the extrusion block to descend until the inclined surface extrudes the rotating wheel, so that the movable baffle moves in the connecting groove to compress the fifth spring until the second connecting hole is connected to the second external connecting hole. At this time, the air that enters the movable groove through the first one-way valve is directly discharged through the second external connecting hole and will not enter the air storage chamber through the second one-way valve again. At this time, the air storage capacity in the air storage chamber reaches the maximum, which is also enough to clean the movable chamber once. This avoids the phenomenon of high air pressure in the air storage chamber due to the long working time of the defrosting mechanism, thereby improving the stability of the inflation mechanism.

Detailed Implementation

[0071] 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.

[0072] This invention provides, for example Figures 1-9An automatic defrosting evaporation device for a quick-freezing tunnel is shown, comprising a base 101, a defrosting mechanism, a suction mechanism, a first sealing mechanism, and a cleaning mechanism. A conveying module 102 is installed inside the base 101, and a refrigeration module 103 is installed inside the base 101. An air supply module 104 is installed on the inner wall of the base 101 above the refrigeration module 103. The defrosting mechanism is located inside the base 101, the suction mechanism is located below the refrigeration module 103, the first sealing mechanism is located above the suction mechanism, and the cleaning mechanism is located inside the defrosting mechanism. When the defrosting mechanism is working, the suction mechanism allows the defrosted water collected in the receiving hopper 203 to be quickly discharged from the freezing tunnel, and also allows the hot air generated during the operation of the defrosting mechanism to be directly extracted. This allows the hot air to pass through the refrigeration module 103 and then be discharged from the freezing tunnel, reducing the residence time of the hot air in the freezing tunnel and thus improving work efficiency.

[0073] The defrosting mechanism includes a fixed frame 201, a heating wire 202, a liquid receiving hopper 203, and an electric telescopic rod 205. The fixed frame 201 is fixedly connected to the inside of the base 101 and is located between the air supply module 104 and the cooling module 103. The heating wire 202 is installed on the inner wall of the fixed frame 201. The liquid receiving hopper 203 is slidably disposed inside the base 101. A suction mechanism is disposed inside the liquid receiving hopper 203. A mounting base 204 is fixedly connected to the inner wall of the base 101. The electric telescopic rod 205 is installed on one side of the mounting base 204. The output end of the electric telescopic rod 205 is connected to one side of the liquid receiving hopper 203 via a drive mechanism. When defrosting is required... When defrosting, the refrigeration module 103 and the conveying module 102 stop working, and the heating wire 202 starts working. At this time, the air blown out by the air supply module 104 blows towards the heating wire 202 and becomes hot air. The hot air then blows towards the refrigeration module 103, which can defrost the refrigeration module 103. Before defrosting, the liquid receiving hopper 203 needs to be moved to the bottom of the refrigeration module 103 by the operation of the electric telescopic rod 205 so that the liquid generated during the defrosting process can flow into the liquid receiving hopper 203 for collection. A sliding seat and a sliding rail are provided between the liquid receiving hopper 203 and the base 101 so that the liquid receiving hopper 203 can move stably under the operation of the electric telescopic rod 205.

[0074] The suction mechanism includes a liquid guide trough 208, a fan blade 210, and a connecting pipe 206. The liquid guide trough 208 is located at the top of the receiving hopper 203. A bottom groove 209 is formed at the bottom end of the inner wall of the liquid guide trough 208. A first sealing mechanism is located inside the bottom groove 209. A rotating rod 211 is rotatably connected to the bottom end of the inner wall of the bottom groove 209. The bottom end of the fan blade 210 is fixedly connected to the top end of the rotating rod 211. A servo motor 212 is installed inside the receiving hopper 203. The output end of the servo motor 212 is connected to the bottom of the rotating rod 211. The connection is via an end drive. A connecting pipe 206 is fixedly inserted into the outer wall of the receiving hopper 203. The interior of the connecting pipe 206 is connected to the interior of the bottom groove 209. A sleeve 207 is fixedly connected to the inner wall of the seat 101. The connecting pipe 206 is movably inserted into the inner wall of the sleeve 207. The outlet end of the sleeve 207 penetrates the inner wall of the seat 101 and extends to the outside of the seat 101. Liquid flowing into the receiving hopper 203 will sequentially pass through the guide groove 208, the bottom groove 209, the connecting pipe 206, and the sleeve 207 before being discharged from the seat 101. 1. To prevent liquid residue from re-frostning inside the tunnel, the outer wall of the connecting pipe 206 and the inner wall of the sleeve 207 are designed with an interference fit, allowing the liquid in the connecting pipe 206 to be stably discharged through the sleeve 207, but not through the space between the connecting pipe 206 and the sleeve 207. The servo motor 212 drives the rotating rod 211 to rotate, which in turn drives the fan blades 210. The fan blades 210 generate suction in the liquid guide groove 208, and this negative pressure helps to quickly discharge the liquid in the connecting pipe 206 and the sleeve 207. It also directly absorbs the hot air during the defrosting process, which is then discharged through the connecting pipe 206 and the sleeve 207, reducing the time hot air stays in the freezing tunnel and thus reducing downtime, improving work efficiency. The servo motor 212, the electric telescopic rod 205, and the heating wire 202 are electrically connected to an external power supply via external switches, allowing operators to control them individually, improving operational safety and convenience.

[0075] The first sealing mechanism includes a fan-shaped baffle 301, a first ring 303, a second ring 304, a connecting piece 307, and a first spring 309. A movable cavity 302 is formed on the inner wall of the bottom groove 209. Multiple fan-shaped baffles 301 are movably disposed inside the movable cavity 302. A cleaning mechanism is used to remove liquid entering the movable cavity 302. A first fixing strip 310 is symmetrically fixed to the inner wall of the first ring 303. A second fixing strip 312 is fixedly connected to the end of the first fixing strip 310. One end of the second fixing strip 312 is fixedly connected to the outer wall of the rotating rod 211. The second ring 304 is disposed inside the movable cavity 302. The inner wall of the second ring 304 is connected to the first ring 307. Connecting plates 305 are fixedly connected at intervals between the outer walls of ring 303. The top end of connecting piece 307 is fixedly connected to the top end of fan-shaped baffle 301. A first connecting rod 306 is fixedly connected between the outer wall of the first ring 303 and the inner wall of the second ring 304. A first connecting hole 308 is opened on one side of connecting piece 307. The first connecting rod 306 is movably inserted into the inner wall of the first connecting hole 308. A first spring 309 is disposed between the inner wall of connecting piece 307 and the second ring 304. The first spring 309 is sleeved on the outer wall of the first connecting rod 306. The four fan-shaped baffles 301 can be combined to form a complete disc, thereby sealing the top of the bottom groove 209, thus making... When the defrosting mechanism is not in operation, multiple sector-shaped baffles 301 can seal the liquid guide groove 208 and the bottom groove 209, thereby preventing cold air in the freezing tunnel from being discharged through the connecting pipe 206 and the sleeve 207. However, when the defrosting mechanism is in operation, as the servo motor 212 drives the rotating rod 211 to rotate, and then, under the connection of the second fixed bar 312 and the first fixed bar 310, the rotation of the rotating rod 211 can drive the first ring 303 to rotate. Then, under the connection of the connecting plate 305, the second ring 304 rotates synchronously with the first ring 303. During the rotation, due to the mutual limiting of the first connecting rod 306 and the first connecting hole 308, the sector-shaped baffles 301... As it rotates, the sector baffles 301, under the action of centrifugal force, move together with the connecting piece 307 toward the second ring 304, thereby separating the four sector baffles 301 and connecting the liquid guide groove 208 with the bottom groove 209, allowing liquid and hot air to enter the bottom groove 209 stably. During the movement of the sector baffles 301 and the connecting piece 307, the first spring 309 is compressed until defrosting is completed. Then the rotating rod 211 stops rotating. At this time, the sector baffles 301 lose the action of centrifugal force and, under the elastic action of the first spring 309, the sector baffles 301 move in the opposite direction to reset, so that the four sector baffles 301 combine to form a disc for sealing.

The air storage chamber 401 is located inside the liquid receiving hopper 203. An air inflation mechanism is provided on the inner wall of the air storage chamber 401.

After defrosting, the second sealing mechanism is unlocked, allowing the air stored in the air storage chamber 401 to enter the movable chamber 302 through the first connecting hole 402. This blows the liquid in the movable chamber 302 into the bottom tank 209, thereby preventing liquid residue in the movable chamber 302.

[0077] The second sealing mechanism includes a stop block 403, a limiting block 417, a third spring 418, and a compression ring 404. The stop block 403 is slidably disposed on the inner wall of the movable cavity 302. The limiting block 417 is fixedly connected to the outer wall of the stop block 403.

Hydraulic oil 411 is provided between the second piston block 410 and the first piston block 406. A fixing ring 412 is fixedly connected to the inner wall of the connecting cavity 409. A second spring 413 is located between the fixing ring 412 and the second piston block 410. When the defrosting mechanism is working, the rotating rod 211 rotates, causing the connecting plate 305 and the second ring 304 to also rotate. At this time, the second piston block 410 inside the connecting plate 305 will also move towards the fixing ring 412 under the action of centrifugal force, and... The second spring 413 is compressed, causing the second piston block 410 to move, which in turn moves the hydraulic oil 411, thereby causing the first piston block 406 to move downwards. The downward movement of the first piston block 406 causes the second connecting rod 407 to move downwards, which in turn causes the compression ring 404 to move downwards. The downward movement of the compression ring 404 presses down on the stop block 403, causing the stop block 403 to block the opening of the first connecting hole 402. This prevents air in the air storage chamber 401 from entering the movable chamber 302 through the first connecting hole 402. Only after defrosting is completed and the connecting plate 305 stops rotating can the second piston block 410 move in the opposite direction under the elastic action of the second spring 413, causing the first piston block 406 and the second connecting rod 407 to rise.At this point, the stop block 403 can rise under the elastic action of the third spring 418, thereby connecting the first connecting hole 402 with the movable cavity 302, allowing air from the air storage cavity 401 to be blown into the movable cavity 302 for cleaning. Since the compression ring 404 rotates together with the second ring 304, and the stop block 403 only moves longitudinally, the compression ring 404 contacts the ball 415 when it presses down on the stop block 403, thus reducing the friction on the rotating compression ring 404 and making the second sealing mechanism work more smoothly.

[0078] The inflation mechanism includes a piston plate 501, a movable groove 502, a second one-way valve 506, and a fourth spring 515. The outer wall of the piston plate 501 is slidably connected to the inner wall of the air storage chamber 401. The movable groove 502 is opened on the inner wall of the air storage chamber 401. A third piston block 503 is slidably connected to the inner wall of the movable groove 502. A moving mechanism is provided between the third piston block 503 and the rotating rod 211. An exhaust mechanism is provided on the inner wall of the movable groove 502. The second one-way valve 506 is installed on the inner wall of the movable groove 502. A first external connection hole 504 is opened on the inner wall of the movable groove 502. A first one-way valve 505 is installed on the inner wall of the first external connection hole 504. The fourth spring 515 is disposed on the piston plate 501. At the bottom end of the piston plate 501, a guide rod 514 is fixedly connected to the bottom end. A guide sleeve 513 is fixedly connected to the bottom end of the inner wall of the gas storage chamber 401. The guide rod 514 is movably inserted into the inner wall of the guide sleeve 513. A fourth spring 515 is sleeved on the outside of the guide rod 514 and the third piston block 503. The moving mechanism includes an elliptical disk 508, a third connecting rod 509, and an annular groove 510. A rotating cavity 507 is opened inside the liquid receiving hopper 203. The elliptical disk 508 is disposed inside the rotating cavity 507. The inside of the rotating cavity 507 is connected to the inside of the movable groove 502. The elliptical disk 508 is fixedly sleeved on the outer wall of the rotating rod 211. The third connecting rod 509 is fixedly connected to one side of the third piston block 503. On the side, an annular groove 510 is formed on the outer wall of the elliptical disk 508. One end of the third connecting rod 509 is inserted into the interior of the annular groove 510. The end of the third connecting rod 509 is symmetrically rotatably connected to a rotating shaft 511. Guide grooves 512 are formed at the top and bottom of the inner wall of the annular groove 510. The rotating shaft 511 is movably disposed on the inner wall of the guide groove 512. When the defrosting mechanism is working, the rotating rod 211 rotates, driving the elliptical disk 508 to rotate. Through the elliptical shape of the elliptical disk 508 and the limiting and guiding of the rotating shaft 511 by the guide groove 512, the third piston block 503 can reciprocate within the movable groove 502, thereby allowing air outside the liquid receiving hopper 203 to pass through the first one-way valve 505. The air enters the movable slot 502 and then passes through the second one-way valve 506 to enter the air storage chamber 401 for collection. Since the second sealing mechanism also works automatically when the defrosting mechanism is working, the air entering the air storage chamber 401 cannot be discharged through the first connecting hole 402. Instead, it can only squeeze the piston plate 501 in the air storage chamber 401, causing the piston plate 501 to move down and compressing the fourth spring 515. After the defrosting mechanism is completed, the second sealing mechanism unlocks, and then the piston plate 501 automatically rises under the elastic action of the fourth spring 515, which blows the air stored in the air storage chamber 401 into the movable chamber 302 through the first connecting hole 402.

[0079] The exhaust mechanism includes a second external connection hole 601, a movable baffle 603, a fifth spring 609, a rotating wheel 606, and a pressing block 607. The second external connection hole 601 is located on the inner wall of the movable groove 502, and a connecting groove 602 is formed on the inner wall of the second external connection hole 601. The interior of the connecting groove 602 is connected to the interior of the air storage chamber 401. The outer wall of the movable baffle 603 is slidably connected to the inner wall of the connecting groove 602. A second connecting hole 604 is formed at the top of the movable baffle 603. The fifth spring 609 is fixedly connected between one side of the movable baffle 603 and the inner wall of the connecting groove 602. A slot 605 is formed on the other side of the movable baffle 603. The rotating wheel 606 is rotatably connected to the inner wall of the slot 605. The pressing block 607 is fixedly connected to the bottom end of the piston plate 501, and an inclined surface 608 is formed at the bottom end of the pressing block 607. The working time of the mechanism cannot be directly limited, but the air storage space in the air storage chamber 401 is limited. As the piston plate 501 descends, it drives the extrusion block 607 to descend until the inclined plane 608 extrudes the rotating wheel 606. This causes the movable baffle 603 to move in the connecting groove 602 and compress the fifth spring 609 until the second connecting hole 604 connects with the second external connecting hole 601. At this time, the air that enters the movable groove 502 through the first one-way valve 505 is directly discharged through the second external connecting hole 601 and will not enter the air storage chamber 401 through the second one-way valve 506. At this time, the air storage capacity in the air storage chamber 401 reaches its maximum, which is also sufficient to clean the movable chamber 302 once. This avoids the phenomenon of high air pressure in the air storage chamber 401 due to the long working time of the defrosting mechanism, thereby improving the stability of the inflation mechanism.
