Further, the described water pipe that spreads is airtight ring pipe, is distributed with some apopores on the described ring pipe.Described apopore aperture equates, and equidistant being arranged on the ring pipe; Or: the grouping of described apopore is arranged, and the aperture of apopore equates in same group, and does not arrange after by forward direction from big to small by direction of rotation in aperture on the same group.
Further, described water receiving unit comprises drip tray, water fender and the water receiving tank that is loop configuration, described water receiving tank is located at the below of described cylindrical shell, and described drip tray is accepted described cylindrical shell and water receiving tank, and described water fender is located at the position between drip tray and the water receiving tank.Described water receiving tank also is connected to described water supply unit.
Advantage of the present utility model is: evaporator of flake ice maker peculiar to vessel of the present utility model adopts the special tube structure design of suitable seawater ice making, and revolving design of spreading water pipe and skates assembly, can realize directly also can carrying out continuously with the seawater ice making, it is little to have volume, accounts for long-pending little, energy-efficient, the environmental protection of deck, simple to operate, characteristics such as applicability is strong.And the inside and outside wall of described inner barrel is equipped with groove, can increase contact area, improves heat exchanger effectiveness, energy savings and raw material.

Fig. 2 is the plan structure schematic diagram of the cylindrical shell of ice making of the present utility model unit.
Fig. 3 is the distribution schematic diagram that spreads apopore one embodiment on the water pipe of the present utility model.
The specific embodiment
See also Fig. 1 to shown in Figure 2, evaporator of flake ice maker peculiar to vessel of the present utility model, an important component part for slice ice machine peculiar to vessel system comprises water supply unit 1, ice making unit 2 and water receiving unit 3, water supply unit 1 supplies water for ice making unit 2, and water receiving unit 3 is positioned at the below of ice making unit 2.
Described ice making unit 2 comprises cylindrical shell 21, driving mechanism 22, rotating shaft 23, spread water pipe 24 and skates assembly 25, described cylindrical shell 21 comprises inner barrel 211 and outer cylinder body 212, space between inner barrel 211 and the outer cylinder body 212 is provided with refrigerant flow path 213, described rotating shaft 23 vertically is arranged on the interior space 214 of inner barrel 21 and by driving mechanism 22 driven rotary, driving mechanism 22 can be reducing motor.Describedly spread water pipe 24 and skates assembly 25 is fixed on the rotating shaft 23, described skates assembly 25 is positioned at the below of spreading water pipe 24 and makes the blade of skates assembly 25 be adjacent to the inwall 2111 of inner barrel 211.Mainly as shown in Figure 2, inwall 2111, the outer wall 2112 of described inner barrel 211 are equipped with groove 215, can increase contact area, improve heat exchanger effectiveness, energy savings and raw material.
Mainly as shown in Figure 1, the described water pipe 24 that spreads is airtight ring pipe, is distributed with some apopores 242 on the ring pipe.Water sprays to the inwall 2111 of inner barrel 211 from the apopore 242 that spreads water pipe 24, and carries out heat exchange with cold-producing medium in the refrigerant flow path 213, and then forms ice sheet at the inwall 2111 of inner barrel 211.The aperture size of ring footpath size, apopore 242 angles and apopore 242 of spreading water pipe 24 is all essential through calculating and experiment and determine.
Described apopore aperture design has dual mode, and first kind is, described apopore 242 apertures equate, and equidistant being arranged on the ring pipe; This design processing is simple, but more not energy-conservation.Second kind as shown in Figure 3: 242 groupings of described apopore are arranged, and the aperture of apopore 242 equates in same group, and does not arrange after by forward direction from big to small by direction of rotation in apopore 242 apertures on the same group; This design processing is complicated a little, but more energy-conservation, because rotating shaft 23 when rotated, the used water yield demand of ice making before is bigger, and required afterwards water need not be so much originally, so the aperture reduces gradually, make water yield generation variation from more to less, avoid the waste of water and the waste of cold-producing medium.
Again as shown in Figure 1, described water receiving unit 3 comprises drip tray 31, water fender 32 and the water receiving tank 33 that is loop configuration, described water receiving tank 33 is located at the below of described cylindrical shell 21, described drip tray 31 is accepted described cylindrical shell 21 and water receiving tank 33, and described water fender 32 is located at the position between drip tray 31 and the water receiving tank 33.Described water receiving tank 33 also is connected to described water supply unit 1, specifically can be the water tank 11 that is connected to water supply unit 1, imports water receiving tank 33 to realize unnecessary water through drip tray 31, through delivery port reflow tank 11, and can be effectively energy-conservation.
Though more than described the specific embodiment of the present utility model; but being familiar with those skilled in the art is to be understood that; our described specific embodiment is illustrative; rather than for the restriction to scope of the present utility model; those of ordinary skill in the art are in modification and the variation of the equivalence of doing according to spirit of the present utility model, all should be encompassed in the scope that claim of the present utility model protects.
