[0046] The technical solution of the utility model is further described in conjunction with the following embodiments.

[0047] Example 1

[0048] A tunnel transport type cryo-hibernation device, such as Figure 1 As shown, a housing 100, a conveying mechanism 300 for conveying frozen objects, a spraying mechanism for precooling the frozen objects by spraying freezing liquid on the frozen objects, a freezing liquid storage chamber 400, and an air supply mechanism 500 for removing freezing liquid attached to the frozen objects are provided. The spraying mechanism and the air supply mechanism 500 are fixedly assembled inside the housing 100, the freezing liquid storage chamber 400 is located inside the housing 100, the conveying mechanism 300 is assembled inside the housing 100, and the spraying mechanism is located above the front end of the conveying mechanism 300, the middle part of the conveying mechanism 300 is located inside the freezing liquid storage chamber 400, and the rear section of the conveying mechanism is located below the air supply mechanism 500. When the freezing device is in normal use, the ground direction is defined as the bottom.

[0049] The tunnel conveyor type freezing equipment of the present invention is also provided with a material receiving rack 700 and a material discharging rack 800. The material receiving rack 700 is located at the material inlet 120 of the shell 100, and the material discharging rack 800 is located at the material outlet 110 of the shell 100. The material discharging rack 800 is used to store the frozen objects to be frozen, and the material receiving rack 700 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 1The shadow in the freezing liquid storage chamber 400 is freezing liquid. The objects above the conveying mechanism 300 in the figure are frozen objects.

[0050] The conveying mechanism 300 is provided with a first conveyor belt 310 for conveying the frozen objects from the outside to the inside of the shell 100, a second conveyor belt 320 for transferring the frozen objects from the first conveyor belt 310, a third conveyor belt 330 for conveying the frozen objects in the freezing liquid, a fourth conveyor belt 340 for transporting the frozen objects out of the freezing liquid, and a fifth conveyor belt 350 for conveying the frozen objects to the outside of the shell 100. The first conveyor belt 310, the second conveyor belt 320, the third conveyor belt 330, the fourth conveyor belt 340 and the fifth conveyor belt 350 are all assembled inside the shell 100. The first conveyor belt 310, the second conveyor belt 320 and the third conveyor belt 330 are arranged horizontally from top to bottom, one end of the first conveyor belt 310 extends to the feed port 120 of the shell 100, the first conveyor belt 310 is located at the lower part of the spray mechanism and is higher than the horizontal position of the freezing liquid storage chamber 400, and the third conveyor belt 330 is located inside the freezing liquid storage chamber 400. The fourth conveyor belt 340 is arranged at an angle, and the fifth conveyor belt 350 is arranged horizontally. One end of the fourth conveyor belt 340 is located inside the cryomnium liquid storage chamber 400 and connected to the third conveyor belt 330. The other end of the fourth conveyor belt 340 is located outside the cryomnium liquid storage chamber 400 and above one end of the fifth conveyor belt 350, and the other end of the fifth conveyor belt 350 extends to the discharge port 110 of the shell 100.

[0051] It should be noted that the first conveyor belt 310 and the second conveyor belt 320 of the conveying mechanism 300 of the utility model are used to increase the freezing time of the frozen objects in the tunnel conveying type freezing device. The fourth conveyor belt 340 and the fifth conveyor belt 350 are divided into two separate conveyor belts. Since one end of the fourth conveyor belt 340 needs to be immersed in the freezing liquid, and since a large amount of freezing liquid is attached to the surface of the fourth conveyor belt 340, most of this part of the freezing liquid will not be transmitted to the fifth conveyor belt 350 but will flow back to the inside of the freezing liquid storage chamber 400, thereby reducing the loss of freezing liquid.

[0052] The air supply mechanism 500 is provided with a first air supply unit 510 for removing the freezing liquid of the frozen objects in the fifth conveyor belt 350 and a second air supply unit 520 for removing the freezing liquid attached to the fourth conveyor belt 340 and the freezing liquid attached to the frozen objects. The first air supply unit 510 and the second air supply unit 520 are both fixedly assembled inside the housing 100. The first air supply unit 510 is located above the fifth conveyor belt 350, and the second air supply unit 520 is located above the fourth conveyor belt 340. The fourth conveyor belt 340 is divided into two sections, the first section is inside the freezing liquid storage chamber 400, and the second section is outside the freezing liquid storage chamber 400. The second air supply unit 520 is located above the second section.

[0053] It should be noted that the purpose of arranging the second air supply unit 520 above the second section of the fourth transmission is to remove the freezing liquid attached to the fourth transmission belt 340 and the freezing liquid attached to the frozen objects, reduce the amount of freezing liquid entering the fifth transmission belt 350, and further reduce the loss of freezing liquid. The first air supply unit 510 and the second air supply unit 520 of the utility model are specifically fans, and the air supply mechanism 500 generates a high-speed airflow through the first air supply unit 510 and the second air supply unit 520 to blow away the attached freezing liquid, and the airflow temperature generated by the first air supply unit 510 and the second air supply unit 520 is less than -40°C. Therefore, the first air supply unit 510 and the second air supply unit 520 will not increase the temperature of the frozen objects.

[0054] The liquid inlet end of the spray mechanism is connected to the freezing liquid storage chamber 400 ; the spray mechanism is provided with multiple spray heads 200 , which are fixedly assembled on the inner wall of the shell 100 , and the spray heads 200 are located directly above the first conveyor belt 310 .

[0055] The housing 100 is provided with openings on both sides. The opening close to the first conveyor belt 310 is used as the feed port 120, and the opening close to the fifth conveyor belt 350 is used as the discharge port 110. The upper wall of the discharge port 110 is a first curved wall 111 for forming a vortex of the cold air, and the first curved wall 111 extends toward the inside of the housing 100; the lower wall of the discharge port 110 is a second curved wall 112 for forming a vortex of the cold air, and the second curved wall 112 extends toward the inside of the housing 100, as shown in FIG. Figure 2 As shown, in Figure 2 The arrow in the middle indicates the airflow direction.

[0056] It should be noted that the first curved wall 111 and the second curved wall 112 enable the airflow generated by the air supply mechanism 500 to be diverted to the inside of the shell 100 when it hits the surface, forming an airflow toward the inside of the shell 100, thereby preventing the freezing liquid from volatilizing from the discharge port 110.

[0057] The area of ​​the housing 100 directly below the fifth conveyor belt 350 is defined as a liquid removal area. The surface of the liquid removal area is an inclined surface 130 , and the inclined surface 130 is inclined toward the cryostasis liquid storage chamber 400 .

[0058] The tunnel conveying type freezing and hibernation equipment works as follows: the operator puts the frozen object into the first conveyor belt 310 from the feed port 120; the first conveyor belt 310 transports the frozen object and then the frozen object is transported to the end of the first conveyor belt 310, and at the same time, the spraying mechanism sprays the freezing and hibernation liquid inside the freezing and hibernation liquid storage chamber 400 to pre-cool the frozen object, and then the frozen object falls from the end of the first conveyor belt 310 to the second conveyor belt 320; the second conveyor belt 320 transports the frozen object and then the frozen object is transported to the end of the third conveyor belt 330 and falls to the third conveyor belt 330. 30, the third conveyor belt 330 allows the frozen objects to be frozen in the freezing liquid, and then the third conveyor belt 330 transports the frozen objects to the fourth conveyor belt 340; the fourth conveyor belt 340 causes the frozen objects to rise and leave the freezing liquid, and at the same time the second air supply unit 520 generates a high-speed low-temperature airflow to remove the freezing liquid attached to the fourth conveyor belt 340 and the freezing liquid attached to the frozen objects; then the objects fall to the fifth conveyor belt 350, and the first air supply unit 510 generates a high-speed low-temperature airflow to continue to remove the freezing liquid attached to the frozen objects, and finally the freezing is completed and transported to the discharge port 110.

[0059] When the total length of the tunnel transport type freezing hibernation equipment is 12m, its freezing capacity is 2t / h. The air flow temperature of the air supply mechanism 500 of the utility model is -45℃.

[0060] The tunnel conveying type freezing hibernation equipment continuously conveys the frozen objects to the inside through the conveying mechanism 300, wherein the spraying mechanism pre-cools the frozen objects by spraying freezing liquid on the front section, and then the conveying mechanism 300 conveys the pre-cooled frozen objects to the freezing liquid storage chamber 400, so that the frozen objects are immersed in the freezing liquid for rapid cooling, and finally the conveying mechanism 300 conveys the frozen objects to the bottom of the air supply mechanism 500, and blows out cold wind below -40°C to blow away the freezing liquid attached to the frozen objects, thereby reducing the freezing liquid being taken away from the outside of the tunnel conveying type freezing hibernation equipment and reducing the loss of freezing liquid. The tunnel conveying type freezing hibernation equipment can perform continuous freezing hibernation operations, and at the same time, by first touching the frozen objects with the freezing liquid for pre-cooling by spraying freezing liquid, and then immersing them in the freezing liquid for freezing hibernation, the freezing hibernation efficiency can be improved.

[0061] Example 2

[0062] A tunnel transport type cryo-hibernation device, such as Figure 3 and Figure 4 The other features are the same as those of the first embodiment, and also have the following features: two baffles 600 are provided for closing the openings, one end of the baffle 600 is located above the corresponding opening and is fixedly assembled on the outside of the housing 100, and the other end of the baffle 600 is detachably mounted on the housing 100;

[0063] During operation, one end of the baffle 600 is clamped on the outside of the housing 100 .

[0064] The baffle 600 is provided with a first sub-plate 610 and a second sub-plate 620. One end of the first sub-plate 610 is hinged to the outside of the housing 100, and the other end of the first sub-plate 610 is hinged to one end of the second sub-plate 620. The other end of the second sub-plate 620 is provided with a notch 621, and the notch 621 is detachably mounted on the housing 100. The housing 100 is provided with a slot 140, and the slot 140 is detachably assembled with the other end of the second sub-plate 620. The lower edge of the slot 140 is integrally connected with a buckle 141, and the buckle 141 is detachably mounted on the notch 621. Figure 5 and Figure 6 shown.

[0065] It should be noted that when working, the operator folds the first sub-plate 610 and the second sub-plate 620, inserting the other end of the second sub-plate 620 into the card slot 140. At this time, under the action of gravity, the notch 621 abuts against the buckle 141, thereby fixing the baffle 600. When not working, the operator lifts the second sub-plate 620, removes the other end of the second sub-plate 620 from the card slot 140, and then covers the opening with the baffle 600 to prevent the opening from being opened and prevent the cryotherapy liquid from volatilizing.

[0066] Compared with the first embodiment, the baffle 600 of the present embodiment can fix the tunnel transport type cryo-hibernation device when it is working without any additional accessories, and can cover the opening when it is not working to prevent the cryo-hibernation liquid from volatilizing.

[0067] 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.
