[0021] The technical scheme in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model, obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0022] Please refer to Figures 1-6The integrated granular ice evaporation condensing device comprises an ice making cylinder 1, and a spiral-shaped ice cutter 2 is rotationally connected in the ice making cylinder 1. The ice cutter 2 is mainly used to form a spiral ice extruding structure by the interaction between the spiral shape of the ice cutter 2 and the inner wall of the ice making cylinder 1. An end cover 4 is arranged at the top of the ice making cylinder 1. The end cover 4 is mainly used to close the ice making cylinder 1 to prevent water or ice from splashing during the ice making process. The end cover 4 and the ice making cylinder 1 are fixedly connected through welding. The welding connection can effectively prevent the gap between the end cover 4 and the ice making cylinder 1 due to thermal expansion and cold contraction, thereby avoiding water leakage and other problems. At the same time, the welding connection does not require additional fasteners, so that the connection position has no protruding fastener head or gap, thereby reducing the volume of the connection position and improving the overall integrity of the device. A plurality of ice outlets 5 are arranged on the end cover 4 along the circumferential direction thereof. The ice outlets 5 are mainly used to smoothly discharge the ice blocks made from the ice making cylinder 1. When the ice cutter 2 rotates and cuts the ice blocks in the ice making cylinder 1, the ice blocks will be pushed to the ice outlets 5 and discharged from the ice outlets 5. An axle hole is arranged at the center of the end cover 4. A rotating shaft 6 is arranged at the top of the ice cutter 2 and is coaxially rotationally connected to the axle hole. This design can ensure that the ice cutter 2 stably rotates in the ice making cylinder 1 and interacts with the spiral thread 8 to cut and extrude the ice blocks. At the same time, the design of the rotating shaft 6 and the axle hole can also ensure the stability and reliability of the ice cutter 2 during rotation.

[0023] Please refer to Figures 1-6The evaporation coil 3 is coaxially fixed to the outer wall of the ice making cylinder 1. The refrigerant flows through the evaporation coil 3. When the refrigerant evaporates in the coil, it absorbs the heat from the surrounding environment, thereby reducing the temperature inside the ice making cylinder 1. The sealing bearing 7 is arranged between the rotating shaft 6 and the shaft hole. The sealing bearing 7 mainly reduces the friction and wear of the rotating shaft 6 during rotation, and prevents water or other impurities from entering the inside of the shaft hole, affecting the normal operation of the equipment. The two groups of helical grooves on the ice cutter 2 are arranged equidistantly along the axial direction of the rotating shaft 6 and form a double helix structure. The diameter of the ice cutter 2 is smaller than the diameter of the ice making cylinder 1. The double helix structure can make more efficient use of the internal space of the ice making cylinder 1, improving the ice making efficiency. At the same time, the design that the diameter of the ice cutter 2 is smaller than the diameter of the ice making cylinder 1 can ensure that the ice cutter 2 does not produce excessive friction with the inner wall of the ice making cylinder 1 during rotation, reducing energy loss and wear. In addition, this design also makes the ice cutter 2 easier to cut into the ice layer, improving the cutting effect. The inner wall of the ice making cylinder 1 is provided with a spiral groove 8 which is recessed relative to the inner wall of the ice making cylinder 1. The pitch of the spiral groove 8 matches the pitch of the ice cutter 2, and the spiral groove 8 and the ice cutter 2 form a spiral ice extrusion structure. This structure can ensure that the ice is continuously extruded and sheared in the ice making cylinder 1, thereby peeling the ice from the inner wall of the ice making cylinder 1 and pushing it to the ice outlet 5. The design of the spiral groove 8 can also make the ice block receive uniform force during extrusion, avoiding cracks or deformation of the ice block due to uneven force. In addition, the spiral groove 8 can also guide the water that has not condensed into ice back to the bottom of the ice making cylinder 1 to continue participating in the ice making process, thereby improving the utilization rate of water resources and the ice making efficiency.

[0024] Working principle: In the utility model, the end cover 4 and the ice making cylinder 1 are connected by welding. The welding connection can effectively prevent the gap between the end cover 4 and the ice making cylinder 1 due to thermal expansion and contraction, and can avoid water leakage between the end cover 4 and the ice making cylinder 1 due to the cold and hot relationship. At the same time, the welding connection does not require additional fasteners, so there is no protruding fastener head or gap at the connection position, thereby reducing the volume of the connection position.

[0025] At the same time, when the ice cutter 2 adopts a double helix structure, the contact area between the ice cutter 2 and the inner wall of the ice making cylinder 1 is larger than that of a single helix structure. This makes more ice be cut and extruded into ice particles in the same rotation time, thereby improving the ice making capacity. Moreover, the two groups of ice cutters 2 can cut ice simultaneously, forming more ice crystals. These ice crystals are then further extruded and shaped under the action of the spiral ice extrusion structure, improving the overall ice making speed.

[0026] And because in the device, the spiral thread 8 and the spiral ice extruding structure of the ice knife 2 are adopted, the design of the spiral thread 8 makes the ice in the ice making cylinder 1 continuously extruded and sheared. When the ice knife 2 rotates in the spiral shape, it will interact with the spiral thread 8, peel the ice from the inner wall of the ice making cylinder 1 and push it to the ice outlet 5, and can ensure that the ice block is uniformly forced during the extrusion, thereby avoiding the cracks or deformation of the ice block due to uneven force, effectively breaking and extruding the ice block, thereby improving the ice extruding efficiency. At the same time, the spiral thread 8 can guide the water that has not condensed into ice to flow back to the bottom of the ice making cylinder 1.
