Description

Technical Field

[0001] The invention relates to the technical field of lobster automatic processing, in particular to a crayfish quick-freezing device. Background Art

[0002] Lobster processing often refers to the conversion of farmed lobsters into various forms of products to meet market demand. During lobster processing, the cleaned lobsters often need to be quick-frozen. In an automated way, the quick-frozen lobsters are reduced in size for easier storage and transportation, reducing logistics costs and quality losses during storage and transportation.

[0003] The existing Chinese patent with announcement number CN220229666U discloses a liquid nitrogen quick-freezing device, including a box body and a bracket. A rolling assembly is installed on the inner side of the bracket and the box body. The rolling assembly includes a main roller and a sliding roller. A loading assembly is placed on the top of the sliding roller. The loading assembly includes a material box and a filter. A driving assembly is installed on the main roller. The driving assembly includes a motor and a gear to avoid direct discharge of low-temperature nitrogen to the outside, saving the consumption of liquid nitrogen. The nitrogen with increased temperature is discharged to the outside of the workshop through a discharge pipe to avoid the danger of excessive nitrogen in the workshop, ensuring the safety of personnel. The device is suitable for quick-freezing processing of crayfish.

[0004] Based on the above situation, the inventors believe that the current quick freezing of lobsters often uses a conveyor belt to transport the lobsters into a freezing warehouse containing a freezing medium. Since lobsters are often sent to the quick freezing process after being cleaned and simply filtered, it is difficult to perform a secondary water filtration in traditional quick freezing warehouses, resulting in ice crystals often attached to the surface of the lobsters, which can easily cause specific gravity errors and affect quality. In addition, the simple conveying and quick freezing method limits the cold air area of ​​the lobsters, making it difficult to comprehensively and dispersedly quick freeze the lobsters.

[0044] The technical solution of the present invention will be clearly and completely described below in conjunction with specific embodiments. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than 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.

[0045] The embodiment of the present invention specifically provides a crayfish quick freezing device, please refer to Figure 1 , including a frame 1, a re-filtration tank 2, a connection warehouse 3, a quick freezing warehouse 4, a gas transmission component 5 and a displacement component 6.

[0046] Among them, a re-filter tank 2 is fixedly arranged on the top of the frame 1, and a connecting chamber 3 and a quick-freezing chamber 4 are fixedly arranged on the re-filter tank 2 in sequence. After the lobster is sent into the re-filter tank 2, a secondary water filtration treatment is performed, and then the lobster is sent into the quick-freezing chamber 4 through the connecting chamber 3 for quick freezing. A refrigeration component 11 is fixedly arranged on the frame 1, and the refrigeration component 11 is connected to the quick-freezing chamber 4 through the air transmission component 5 to provide quick-freezing cold air for the quick-freezing chamber 4;

[0047] For further information, please refer to Figure 2 The re-filtration tank 2 includes a tank body 21 fixedly connected to the frame 1 on the outside, a feed pipe 22 fixed to the top of the tank body 21, a drain pipe 23 connected to the bottom of the tank body 21 and a water filtering mechanism arranged inside the tank body 21, through which the crayfish fed in are subjected to secondary water filtering treatment.

[0048] For details, please refer to Figure 3 The water filtering mechanism includes a dispersion component 24 located below the feed pipe 22, a water-spinning component 25 connected to the dispersion component 24 at the top, a water filtering component 26 fixed to the bottom end of the tank body 21, a discharge component 27 connected to the water filtering component 26 at the top, and a driving component 28 connected to the water-spinning component 25 and the discharge component 27. The driving component 28 drives the discharge component 27 and the water-spinning component 25 to move, so that the water-spinning component 25 can spin the water on the lobster and disperse the material through the discharge component 27.

[0049] Please refer to Figure 4 The dispersion assembly 24 includes a conical disk 241 coaxially arranged in the tank body 21, a fixing frame 242 fixed to the inner wall of the tank body 21 at one end, and a fixing column 243 coaxially fixed to the bottom end of the conical disk 241. The other end of the fixing frame 242 is fixed to the conical disk 241, so that when the lobster falls into the conical disk 241, it can slide and disperse to the surroundings in a centrifugal manner along the upper surface of the conical disk 241.

[0050] During implementation, the water-throwing assembly 25 includes an inner cylinder 251 and an outer cylinder 252 coaxially arranged in the tank body 21. The top ends of the inner cylinder 251 and the outer cylinder 252 are fixed to the periphery of the conical disk 241 and the inner wall of the tank body 21 respectively through the first connecting cloth 253. A space for lobster feeding is formed between the outer side of the inner cylinder 251 and the outer cylinder 252. A first frame rod 254 is fixed in the space to fix the inner cylinder 251 and the outer cylinder 252 as a whole through the first frame rod 254. After the lobster slides off the conical disk 241, it can first slide to the feeding space outside the inner cylinder 251 for continuing to feed. There is a gap between the outer side of the outer cylinder 252 and the tank body 21 to provide space for the horizontal movement of the outer cylinder 252. The inner wall of the inner cylinder 251 is fixed to the fixed column 243 through the guide rod assembly, thereby ensuring the activity stability of the inner cylinder 251.

[0051] The guide rod assembly includes a fixed cylinder 255 fixedly connected to the inner wall of the inner cylinder 251, a slide rod 256 with one end slidably connected to the inside of the fixed cylinder 255, and a spring 257 fixed between the fixed cylinder 255 and the slide rod 256. The other end of the slide rod 256 is fixedly connected to the fixed column 243. When the inner cylinder 251 is subjected to a horizontal push and pull force, it will drive the fixed cylinder 255 and the slide rod 256 to slide and cooperate, and the elastic force of the spring 257 will improve the activity reset effect of the inner cylinder 251.

[0052] Furthermore, the water filtering assembly 26 includes a sieve plate 261 fixedly connected to the inner wall of the tank body 21, a discharge port 262 coaxially opened on the tank body 21 and the sieve plate 261, and a retaining tube 263 arranged in the discharge port 262. The outer wall of the retaining tube 263 is fixed to the discharge port 262 by a second frame rod 264. The sieve plate 261 is provided with sieve holes, and the water thrown off the lobster can flow into the bottom of the tank body 21 along the sieve holes and be discharged outwardly through the drain pipe 23.

[0053] The discharge assembly 27 includes an outer ring 271 and an inner ring 272 coaxially arranged below the discharge port 262. The outer ring 271 and the inner ring 272 are fixed by a third frame rod 273, and the tops of the outer ring 271 and the inner ring 272 are fixedly connected to the discharge port 262 and the retaining tube 263 respectively by a second connecting cloth 274, so that after the lobster falls on the sieve plate 261, it continues to be discharged from the discharge port 262 and falls between the outer ring 271 and the inner ring 272. A positioning assembly connected to the driving assembly 28 is arranged inside the inner ring 272, and the outer ring 271 and the inner ring 272 are reciprocated left and right by the driving assembly 28, so as to adjust the left and right feeding positions of the lobster and avoid the lobster feeding direction being single;

[0054] Specifically, the driving assembly 28 includes a support cylinder 281 coaxially arranged below the inner ring 272, a support rod 282 fixed at one end to the support cylinder 281, a rotating rod 283 rotatably mounted on the support cylinder 281, a rotating disk 284 fixedly connected to the rotating rod 283 at the bottom end, a pull rod 285 rotatably connected to the upper surface of the rotating disk 284 at one end, a support disk 286 fixedly arranged below the support rod 282, and a motor 287 fixed to the outer side of the support disk 286, the output shaft of the motor 287 is fixed to the rotating rod 283, so that the rotating rod 283 is driven to rotate by the motor 287, and the pull rod 285 The other end is rotatably connected to the inner cylinder 251. When the rotating rod 283 rotates, the rotating disk 284 can be driven to rotate synchronously, so that the pull rod 285 applies a push-pull force to the inner cylinder 251, allowing the inner cylinder 251 and the outer cylinder 252 to reciprocate left and right, so that when the lobster is fed between the inner cylinder 251 and the outer cylinder 252, it can obtain a reciprocating push-pull vibration force, which is convenient for shaking out the moisture on the surface of the lobster and making the moisture fall under the sieve plate 261. The lobster that has filtered out the moisture for the second time can continue to be fed from the discharge port 262 and fall between the outer ring 271 and the inner ring 272 to continue feeding.

[0055] For further information, please refer to Figure 3 and Figure 4 The connecting chamber 3 includes a chamber body 31 fixedly connected to the tank body 21 at the top and a third connecting cloth 32 fixedly arranged at the bottom of the chamber body 31. The other end of the support rod 282 is fixedly connected to the chamber body 31, thereby providing a stable support for the support tube 281. It is worth noting that the three connecting cloths 32 are all made of rubber material, so as to facilitate the stretching of the activity while ensuring that the lobster does not leak out;

[0056] Please refer to Figure 5 The positioning assembly includes a push rod 275 fixed to the outside of the rotating rod 283, a matching plate 276 symmetrically fixed to the inner wall of the inner ring 272, and an undulating slope 277 arranged on the matching plate 276 near the push rod 275. The outer end of the push rod 275 slides with the undulating slope 277, and the outer side of the outer ring 271 slides linearly along the straight rod 278. When the rotating rod 283 rotates, it will drive the push rod 275 to rotate synchronously, and make the push rod 275 apply force to the undulating slopes 277 symmetrically arranged on both sides one by one, first apply force to the undulating slope 277 on the left side through rotation, so that after the matching plate 276 is subjected to force, it drives the outer ring 271 to move left along the straight rod 278 in a straight line, and after the push rod 275 is separated from the undulating slope 277, it rotates and contacts the undulating slope 277 at the right end, so that the outer ring 271 moves right, so that when the lobster is sent out in the outer ring 271 and the inner ring 272, it can be dispersed in the left and right directions.

[0057] For further information, please refer to Figure 3The quick-freezing bin 4 includes a vertical bin 41 fixedly connected to the third connecting cloth 32 at the top, and a partition 42 fixedly arranged inside the vertical bin 41. Two conveying chambers 43 are formed in the vertical bin 41 through the partition 42. A retarding component 44 is arranged in the conveying chamber 43, so that the lobsters can be dispersedly fed into different conveying chambers 43 after being dispersedly fed to the left and right sides, so as to avoid excessive accumulation of the lobsters during quick freezing, which affects the quick freezing effect. The vertical bin 41 adopts a bent structure, and the lobsters can be fed by gravity, which is more convenient. At the same time, they can also be dispersed and quick-frozen to improve the quick freezing efficiency. Moreover, the retarding component 44 can prevent the lobsters from being fed too quickly, thereby ensuring the quick freezing effect.

[0058] Please refer to Figure 6 The deceleration component 44 is provided at more than two locations along the surface of the conveying chamber 43, so that the lobster can be sufficiently decelerated during the feeding process. The deceleration component 44 includes a first baffle 441 and a second baffle 442 fixedly provided on the inner wall of the conveying chamber 43. The first baffle 441 and the second baffle 442 are arranged at intervals along the width direction of the conveying chamber 43. The first baffle 441 and the second baffle 442 are arranged in an up-and-down staggered manner, so that when the lobster is fed, the staggered blocking effect of the first baffle 411 and the second baffle 442 can slow down the feeding speed, so that the lobster can be fully contacted with the cold air for cooling;

[0059] For further information, please refer to Figure 7 The gas delivery component 5 includes a delivery pipe 51 connected to the refrigeration component 11 at the bottom, a side pipe 52 connected to the delivery pipe 51 at one end, a three-way pipe 53 connected to the delivery chamber 43 at the output end, and a hose 54 connected between the side pipe 52 and the three-way pipe 53. An empty slot 12 is opened on the frame 1, and the side pipe 52 is inserted into the empty slot 12. The refrigeration component 11 is a refrigeration equipment commonly used in existing lobster processing and is not described in detail here. The quick-frozen cold air is delivered to the delivery pipe 51 through the refrigeration component 11, and is delivered to the four delivery chambers 43 through the three-way pipe 53 to complete the cold delivery to the inside of the delivery chamber 43.

[0060] Please refer to 1 and Figure 2 The displacement assembly 6 includes a guide assembly 61 fixed between the vertical bin 41 and the frame 1 and a reciprocating assembly 62 fixed to the outer side of the vertical bin 41. The reciprocating assembly 62 applies force to the vertical bin 41, so that the vertical bin 41 can maintain a straight line movement forward and backward on the frame 1 through the guide assembly 61, so that the vertical bin 41 can reciprocate slightly forward and backward, thereby improving the smooth feeding of lobsters between the baffles and avoiding jamming.

[0061] Specifically, the guide assembly 61 includes a slide bar 611 fixed to the vertical bin 41 at one end and a support 612 fixed to the outer side of the frame 1. The outer wall of the slide bar 611 is slidably arranged on the support 612, so that when the vertical bin 41 is subjected to force, the slide bar 611 can be driven to slide linearly on the support 612.

[0062] Among them, the reciprocating component 62 includes a push cylinder 621, a connecting rod 622 one end of which is fixedly connected to the output end of the push cylinder 621, and a fixed plate 623 fixedly arranged on the outside of the vertical bin 41. The outer side of the push cylinder 621 is fixedly connected to the frame 1 through a mounting seat 624, and the other end of the connecting rod 622 is fixedly connected to the fixed plate 623. The connecting rod 622 can be pushed and pulled back and forth by the push cylinder 621, so that the vertical bin 41 can move back and forth, meeting the needs of smooth lobster unloading, so that the lobster can finally be quickly frozen from the vertical bin 41 and fall out from the bottom of the vertical bin 41.

[0063] The control method of the present invention is to control by manually starting and closing the switch. The wiring diagram of the power element and the provision of power supply are common knowledge in the field, and the present invention is mainly used to protect mechanical devices, so the present invention will no longer explain the control method and wiring layout in detail.

[0064] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
