[0016] An evaporator for a tube ice machine, as Figure 1 , 2, as shown in FIGS. 3, it includes a tank body 1. A transverse plate 2 is fixedly installed inside the tank body 1. The transverse plate 2 is located on the upper side inside the tank body 1. The transverse plate 2 divides the tank body 1 into a first cavity 3 and a second cavity 4. Several ice-making tubes 5 are fixedly installed on the transverse plate 2. The several ice-making tubes 5 are evenly distributed along the circumference inside the tank body 1. The two ends of the ice-making tube 5 are sequentially communicated with the first cavity 3 and the outside. There are a plurality of reserved holes on the transverse plate 2. The ice-making tubes 5 are respectively fixedly installed in the corresponding reserved holes. The upper ends of the ice-making tubes 5 extend into the first cavity 3. A first through hole is opened at the bottom of the tank body 1 corresponding to the ice-making tube 5. The bottom of the ice-making tube 5 is fixedly installed in the corresponding first through hole. A water inlet pipe 6 is communicated and installed on one side of the first cavity 3. An inlet opening communicated with the first cavity 3 is opened on the part of the tank body 1 located in the first cavity 3. The water inlet pipe 6 is fixedly installed in the inlet opening. A hot gas inlet pipe 13, a hot gas outlet pipe 7, a refrigerant inlet pipe 8, and a refrigerant outlet pipe 9 are sequentially communicated and installed on both sides of the second cavity 4. A first baffle plate 10 and a second baffle plate 11 are arranged inside the second cavity 4. The first baffle plate 10 and the second baffle plate 11 are arranged vertically. The first baffle plate 10 and the second baffle plate 11 are sequentially arranged on both sides of the tank body 1 and have different heights. It is characterized in that: both the first baffle plate 10 and the second baffle plate 11 are semi-circular plates and can be spliced into a complete circular plate. The first baffle plate 10 and the second baffle plate 11 are slidably installed inside the second cavity 4. The outer circumferences of the first baffle plate 10 and the second baffle plate 11 are in sliding contact and cooperation with the inner wall of the tank body 1. Through slots 12 are opened on the first baffle plate 10 and the second baffle plate 11 corresponding to the ice-making tubes 5. Semi-circular through slots are opened on the sides of the first baffle plate 10 and the second baffle plate 11 close to each other corresponding to the ice-making tubes 5. The two semi-circular through slots can be spliced into a through slot 12. The ice-making tubes 5 are slidably installed in the corresponding through slots 12. A linear movement mechanism capable of driving the first baffle plate 10 and the second baffle plate 11 to move up and down is provided on the tank body 1. The structure of the utility model is simple and ingenious. It can drive the baffle plate to move up and down, increase the fluidity of the refrigerant, enable the refrigerant to fully exchange heat with the water in the ice-making tube 5, and at the same time can scrape the frost or ice on the outer periphery of the refrigeration tube 5 to prevent the attachment of frost or ice on the outer periphery of the ice-making tube 5 from affecting the ice-making efficiency. It can meet the actual needs and is suitable for popularization.When the present utility model is used, first, water is introduced into the first cavity 3 through the water inlet pipe 6. When the height of the water in the first cavity 3 is higher than the height of the ice-making tube 5, the water flows into the ice-making tube 5. At the same time, a refrigerant is introduced into the second cavity 4 through the refrigerant inlet pipe 8. The refrigerant enters the second cavity 4 and exchanges heat with the water in the ice-making tube 5. The temperature of the refrigerant rises, and the temperature of the water drops below the freezing point. After the heat exchange, the refrigerant is discharged from the tank body 1 through the refrigerant outlet pipe 9. The water freezes in the ice-making tube 5. After reaching the required thickness, hot air is introduced into the tank body 1 through the hot air inlet pipe 13. The ice layer in contact with the ice-making tube 5 of the tubular ice melts and falls off from the refrigeration tube 5. Finally, the hot air is discharged from the tank body 1 through the hot air outlet pipe 7. During this process, the linear movement mechanism is controlled to work. The linear movement mechanism drives the first baffle 10 and the second baffle 11 to move, which can increase the fluidity of the refrigerant in the second cavity 3, so that the refrigerant can fully exchange heat with the water in the ice-making tube 5. During this process, the ice-making tube 5 is always in sliding contact and cooperation with the corresponding through groove 12, which can scrape off the frost or ice attached to the outer periphery of the ice-making tube 5, preventing the frost or ice attached to the outer periphery of the ice-making tube 5 from affecting the ice-making efficiency.

[0017] Specifically, as shown in the figure, the linear movement mechanism in this embodiment includes a lead screw 20. The lead screw 20 is rotatably installed on the tank body 1. The lead screws 20 are symmetrically distributed left and right. A nut 21 is installed in threaded cooperation with the outer periphery of the lead screw 20.

The nuts 21 are respectively fixedly installed in the corresponding second through holes. A driving device capable of driving the two lead screws 20 to rotate is provided on the tank body. The driving device is controlled to drive the lead screw 20 to rotate. The nut 21 drives the corresponding first baffle 10 or second baffle 11 to move up and down. When the first baffle 10 or the second baffle 11 moves up and down, the ice-making tube 5 is in sliding contact and cooperation with the corresponding through groove 12. The first baffle 10 or the second baffle 11 can scrape the outer periphery of the ice-making tube 5.

[0018] Specifically, as shown in the figure, the driving device in this embodiment includes a biaxial motor 30, which is fixedly installed on the tank body 1. One end of the lead screw 20 extends out of the tank body 1. Reserved holes are provided on both the cross plate 2 and the tank body 1. The outer circumference of the lead screw 20 is rotatably installed in the corresponding reserved hole through a sealed bearing. One end of the lead screw 20 extends out of the tank body 1 through the reserved hole on the tank body 1. Coaxial first bevel gears 31 are respectively fixedly installed on the lead screw 20. Coaxial horizontal shafts 32 are respectively fixedly installed on the output shafts of the biaxial motor 30. The two horizontal shafts 32 are symmetrically distributed left and right. The horizontal shaft 32 is rotatably installed on the tank body 1. The outer circumference of the horizontal shaft 32 is rotatably connected to the inner hole of the shaft seat through a bearing. The shaft seat is fixedly installed on the tank body 1. Coaxial second bevel gears 33 are respectively fixedly installed on the horizontal shaft 32. The first bevel gear 31 is meshed and cooperated with the corresponding second bevel gear 33. When the biaxial motor 30 is started, the output shaft of the biaxial motor 30 can drive the horizontal shaft 32 and the second bevel gear 33 to rotate. The second gear 33 drives the corresponding first bevel gear 31 to rotate, and the first bevel gear 31 drives the corresponding lead screw 20 to rotate.

[0019] Further, as shown in the figure, the lead screw 20 in this embodiment is a reciprocating lead screw. The reciprocating lead screw can drive the nut 21 to move up and down reciprocally without changing the rotation direction of the output shaft of the biaxial motor 30.

[0020] Further, as shown in the figure, a partition plate 50 is fixedly installed at the bottom of the tank body 1 in this embodiment. The partition plate 50 and the cross plate 2 cooperate to divide the tank body 1 into a first cavity 3, a second cavity 4, and a third cavity 51. Several reserved holes are respectively opened on the partition plate 50. The ice-making pipe 5 is fixedly installed in the corresponding reserved hole and passes through the corresponding reserved hole. Horizontal pipes 52 are respectively connected and installed on both sides of the third cavity 51. The third cavity 51 can be communicated with the outside through the horizontal pipes 52.

[0021] Further, as shown in the figure, two fixing rings 60 are respectively provided on the outer periphery of the lead screw 20 in this embodiment. In this embodiment, there are four fixing rings 60, and the fixing rings 60 are respectively fixedly installed in the tank body 1. The fixing rings 60 are coaxial with the corresponding lead screw 20. The fixing rings 60 do not affect the movement of the nut 21. A guide block 61 is fixedly installed on one side within the circumference of the fixing ring 60. A coaxial spring rod 62 is fixedly installed on the outer periphery of the lead screw 20. The fixed ends of the spring rods 62 are respectively fixedly installed on the lead screw 20. When the movable end of the spring rod 62 contacts the guide block 61, it can be gradually compressed. The side of the guide block 61 in contact with the movable end of the spring rod 62 is an arc-shaped inclined surface. One side of the guide block 61 is fixedly connected to the fixing block 60, and there is a height difference between the other side of the wire guide block 61 and the fixing ring 60. When the lead screw 20 rotates, it can drive the spring rod 62 to rotate. When the spring rod 62 contacts the guide block 61, the movable end of the spring rod 62 is gradually compressed. When the spring rod 62 separates from the guide block 61, the movable end of the spring rod 62 elongates, which can give a vibration force to the fixing ring 60, drive the fixing ring 60 to vibrate, and thus drive the tank body 1 to vibrate, thereby accelerating the shedding of the ice in the ice-making tube 5.
