The storage chamber 400 is located inside the main body, and the spraying mechanism and the conveying mechanism 300 are both assembled inside the main body, and the spraying mechanism is located at the front end of the conveying mechanism 300. The main body is provided with a shell 100 and an air supply mechanism 500 for removing the freezing liquid attached to the frozen object, and the spraying mechanism, the air supply mechanism 500 and the conveying mechanism 300 are all assembled inside the shell 100.

[0046] It should be noted that the air supply mechanism 500 of the present invention is used to remove the freezing liquid attached to the surface of the frozen object after freezing. The air supply mechanism 500 of the present invention is specifically a fan, and the air flow temperature generated by the air supply mechanism 500 is -45°C.

[0047] The freezing device is also provided with a material receiving rack 600 and a material discharging rack 700. The material receiving rack 600 is located at the material inlet of the housing 100, and the material discharging rack 700 is located at the material outlet of the housing 100. The material discharging rack 700 is used to store the frozen objects to be frozen, and the material receiving rack 600 is used to collect the frozen objects that have been frozen. Figure 1 In the figure, the arrow indicates the direction of transportation of frozen objects. Figure 1 The shadow in the storage chamber 400 is the freezing liquid. The frozen object is above the conveying mechanism 300 in the figure. The spray mechanism is provided with a spray head 200 and a pump body (not shown in the figure), and the spray head 200 is fixedly assembled inside the main body. The pump body is arranged outside the main body, and the liquid inlet of the pump body is connected to the storage chamber 400 by a pipeline, and the spray head 200 is connected to the liquid outlet of the pump body.

[0048] like Figures 2 to 4 As shown, the spray head 200 is provided with an upper cover 210, a spray ring 220 for dispersing the cryo-hibernation liquid and a rotating core 230 for generating a rotating liquid flow. The upper cover 210 is sealingly fastened to the upper surface of the spray ring 220, and the rotating core 230 can be rotatably and sealably assembled inside the spray ring 220, and the inside of the upper cover 210 is in contact with the rotating core 230.

[0049] like Figure 5 and Figure 6 As shown, the rotating core 230 is provided with a rotating vane 231 and an extension tube 232. The rotating vane 231 can be rotatably sealed and assembled inside the spray ring 220. The interior of the upper cover 210 abuts against the upper surface of the rotating vane 231. The extension tube 232 is integrally connected to the lower surface of the rotating vane 231, and the extension tube 232 protrudes from the spray ring 220. The central axis of the rotating vane 231 is colinear with the central axis of the extension tube 232. The outer diameter of the extension tube 232 increases from top to bottom.

[0050] The rotor 231 is provided with a plurality of through swirl holes 233, which are evenly arranged around the rotor 231, and all the swirl holes 233 have the same swirl direction. The swirl holes 233 are located on the outer periphery of the extension tube 232; the cryo-hibernation liquid sprayed from the swirl holes 233 diffuses to the surroundings along the outer surface of the extension tube 232.

[0051] The cross-sectional area of ​​the swirl hole 233 is 20 times the cross-sectional area of ​​the first spray hole 234 .

[0052] It should be noted that the spray ring 220 disperses the frozen dormant liquid into smaller liquid flows and sprays them downward, while the swirl holes 233 in the swirl vane 231 cause the frozen dormant liquid to generate a larger swirl liquid flow, thereby spraying the frozen dormant liquid to a farther area. At the same time, after the swirl, the frozen dormant liquid generates swirl potential energy, which can be drawn into the air during the spraying process, driving the liquid flow of the spray ring 220 to disperse outward. Moreover, after the swirl liquid flow sprays out the swirl vane 231, it spreads conically along the surface of the extension tube 232, so that the water flow is dispersed and further covers a larger area.

[0053] The rotary vane 231 is also provided with a plurality of through first spray holes 234 and abutment grooves 235. The first spray holes 234 are located directly above the extension tube 232 and are surrounded by the abutment grooves 235. The abutment grooves 235 and the extension tube 232 are rotatably embedded. The freezing liquid sprayed from the first spray holes 234 is sprayed from the inside of the extension tube 232 to the outside.

[0054] It should be noted that the first spray hole 234 is used to spray the freezing liquid to the bottom of the spray head 200. The abutment groove 235 and the extension tube 232 are rotatably embedded, which can prevent the rotating core 230 from being dislocated.

[0056] The outer tube 212 is provided with a plurality of liquid outlet holes 214 ; the freezing liquid enters the outer tube 212 from the outer tube 212 , and then part of the freezing liquid is sprayed out of the spray head 200 from the rotating core 230 ; the other part of the freezing liquid enters the interior of the cover body 211 through the liquid outlet holes 214 , and then sprays out of the spray head 200 from the spray ring 220 .

[0057] like Fig. 9 As shown, the spray ring 220 is provided with a plurality of second spray holes 221 and an assembly hole 222 for rotationally sealing and assembling the rotary vane 231 . The rotary vane 231 can be rotationally sealed and assembled inside the assembly hole 222 .

[0058] The conveying mechanism 300 is provided with a first conveyor belt 310, a second conveyor belt 320, a third conveyor belt 330 for conveying external frozen objects to the inside of the shell 100, a fourth conveyor belt 340 for transferring frozen objects on the third conveyor belt 330, and a fifth conveyor belt 350 for conveying frozen objects to the outside of the shell 100. The first conveyor belt 310 is located inside the storage cavity 400, the second conveyor belt 320 is connected to the first conveyor belt 310, and one end of the second conveyor belt 320 is located inside the storage cavity 400, and the other end of the second conveyor belt 320 is located outside the storage cavity 400. The third conveyor belt 330 is located below the spray mechanism, the fourth conveyor belt 340 is located between the third conveyor belt 330 and the first conveyor belt 310, the fifth conveyor belt 350 is located below the second conveyor belt 320, and the fifth conveyor belt 350 is located directly below the air supply mechanism 500.

[0059] It should be noted that the third conveyor belt 330 and the fourth conveyor belt 340 of the transmission mechanism 300 of the utility model are used to increase the freezing time of the frozen objects in the tunnel freezing device. When the freezing device is in normal use, the ground direction is defined as the bottom.

[0060] The freezing and hibernation equipment works as follows: the operator puts the frozen objects into the third conveyor belt 330 from the feed port; the third conveyor belt transports the frozen objects and then the frozen objects are transported to the end of the fourth conveyor belt 340, and at the same time, the spraying mechanism sprays the freezing and hibernation liquid inside the storage chamber 400 to pre-cool the frozen objects, and then the frozen objects fall from the end of the third conveyor belt 330 to the fourth conveyor belt 340; the fourth conveyor belt 340 transports the frozen objects and then the frozen objects are transported to the end of the fourth conveyor belt 340 and fall to the first conveyor belt 310, the first conveyor belt 310 makes the frozen objects inside the freezing and hibernation liquid, and then the first conveyor belt 310 transports the frozen objects and enters the second conveyor belt 320; the second conveyor belt 320 makes the frozen objects rise and leave the freezing and hibernation liquid; then the frozen objects fall from the second conveyor belt to the fifth conveyor belt 350, the air supply mechanism 500 generates a high-speed airflow to remove the freezing and hibernation liquid attached to the frozen objects, and finally the freezing and hibernation are completed and transported to the discharge port.

[0061] When the total length of the freezing device is 12m, the freezing capacity is 2t / h. The air flow temperature of the air supply mechanism 500 of the utility model is -45℃.

[0062] The freezing device with spray pre-cooling function continuously transports the frozen objects to the inside through the conveying mechanism 300, and makes the frozen objects be transported in the freezing liquid for continuous freezing operation, thereby improving the freezing efficiency. Moreover, the freezing device sprays the freezing liquid in the storage chamber 400 onto the surface of the frozen objects through the spraying mechanism at the front end of the conveying mechanism 300, so as to achieve pre-cooling of the frozen objects and improve the freezing effect. The spray head 200 of the utility model sprays the freezing liquid to cover the entire surface by generating a rotating liquid flow.

[0063] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit the protection scope of the utility model. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the utility model.
