Technical Field

[0001] This invention belongs to the technical field of artificial snowmaking devices, and in particular relates to an integrated ice-making and snow-making evaporator based on a flake ice evaporator. Background Technology

[0002] Flake ice evaporators have existed for many years and have been developed since the 1970s. Their structure is simple and their performance is stable. There have been no structural changes, resulting in no functional innovation. Their main function is limited to the production of flake ice.

[0003] With the emergence of the demand for high-temperature snowmaking, since 2000 only a small number of companies have produced artificial snow by first using flake ice evaporators to make ice, and then combining it with other independent crushing mechanisms. Summary of the Invention

[0004] The purpose of this invention is to provide an integrated ice-making and snow-making evaporator based on a flake ice evaporator, which integrates the flake ice evaporator and the snow-making mechanism into one unit, and can make ice or snow as needed.

[0005] The present invention adopts the following technical solution: an integrated ice-making and snow-making evaporator based on a flake ice evaporator, comprising a flake ice evaporator, wherein the ice outlet of the flake ice evaporator is located at its bottom;

[0006] The main shaft of the flake ice evaporator is a hollow main shaft, and a rotating shaft is inserted inside the main shaft. The top and bottom ends of the rotating shaft extend out of the flake ice evaporator.

[0007] The rotating shaft and the main shaft are set coaxially;

[0008] An impeller is mounted at the bottom of the shaft, and a motor is connected to the top of the shaft.

[0009] Furthermore, the impeller includes a shaft, and a number of blades are evenly arranged on the outer circumference of the shaft;

[0010] The wheel axle is connected to and coaxially mounted with the rotating shaft;

[0011] The width direction of the blade is the same as the length direction of the shaft.

[0012] Furthermore, a guard plate is provided at the bottom of the impeller, and the guard plate is arranged perpendicular to the impeller shaft.

[0013] Furthermore, the guard plate is a circular plate, and the radius of the guard plate is less than or equal to the sum of the radius of the wheel axle and the length of the blade.

[0014] Furthermore, the impeller also includes a retaining ring, the inner ring of which is connected to the free end of each blade.

[0015] Furthermore, the motor is mounted on top of the flake ice evaporator via a bracket.

[0016] Furthermore, a guide tube is installed on the ice outlet of the flake ice evaporator. The guide tube is funnel-shaped, and its top opening is larger than its bottom opening.

[0017] The bottom opening of the guide tube is located directly above the impeller.

[0018] Furthermore, there is a gap between the outer circumferential surface of the rotating shaft and the inner circumferential surface of the main shaft.

[0019] Furthermore, a bearing is installed between the rotating shaft and the main shaft.

[0020] The beneficial effects of this invention are: by modifying the main shaft of the flake ice evaporator and inserting the impeller shaft inside the main shaft, the flake ice evaporator and the crushing mechanism located at its ice outlet are integrated into one unit, simplifying the structure.

[0029] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0030] Currently, no innovative improvements have been made to the structure of the flake ice evaporator. The flake ice evaporator is only used for ice making, and the produced flake ice is then transferred to the snowmaking device for snow production. However, the flake ice transfer process needs to be adjusted according to the amount of snow to be produced. Furthermore, since the current demand is for high-temperature snowmaking, some of the flake ice will melt during the transfer process, thereby changing the size and weight of the flake ice raw material and affecting the snowmaking effect.

[0031] This invention modifies the structure of the central drive shaft of the flake ice evaporator by incorporating a coaxial powder ice mechanism into the flake ice evaporator body. This allows a single unit to produce ice or snow according to different user needs without requiring any external independent equipment, thus fulfilling the structural requirement of an integrated ice and snow function.

[0032] This invention discloses an integrated ice-making and snow-making evaporator based on a flake ice evaporator, such as... Figure 1 and Figure 2 As shown, it includes a flake ice evaporator 10, with the ice outlet of the flake ice evaporator 10 located at its bottom; the main shaft 11 of the flake ice evaporator 10 is a hollow main shaft, and a rotating shaft 30 is inserted inside the main shaft 11, with both the top and bottom ends of the rotating shaft 30 extending out of the flake ice evaporator 10; the rotating shaft 30 is coaxially arranged with the main shaft 11; an impeller 60 is installed at the bottom end of the rotating shaft 30, and a motor 20 is connected to the top end of the rotating shaft 30.

[0033] This invention modifies the main shaft 11 of the flake ice evaporator 10 by inserting the rotating shaft 30 of the impeller 60 through the main shaft 11, thereby integrating the flake ice evaporator 10 and the crushing mechanism located at its ice outlet into one unit, integrating ice making and snow making into one unit. It can make ice or snow according to user needs, improve snow making efficiency, and adjust the ice production amount according to snow making requirements.

[0034] The flake ice evaporator 10 is a type of ice maker, generally an industrial ice maker, which produces flake ice. Flake ice is thin, dry, and loose white ice, with a thickness of 10 to 15 millimeters, an irregular shape, and a diameter of approximately 12 to 45 millimeters. Flake ice has no sharp edges and will not puncture frozen objects.

[0035] In this embodiment of the invention, flake ice can be directly produced through the flake ice evaporator 10. The flake ice is discharged from the ice outlet under the action of gravity. When the flake ice falls to the position of the impeller 60, it is broken into snow by the blades 61, forming snowflakes that fall downwards. The snowmaking device of this invention can be installed at a high place, so that snowflakes fall naturally. It can be applied to the tops of large shopping malls, film and television bases, etc., to simulate snow scenes.

[0036] In this embodiment of the invention, although the main shaft 11 of the flake ice evaporator 10 is made hollow, its outer shell thickness can be increased to enhance its strength.

[0037] By extending both the top and bottom ends of the rotating shaft 30 out of the flake ice evaporator 10, the snowmaking mechanism can be prevented from affecting the operation of the flake ice evaporator 10, minimizing modifications to the flake ice evaporator 10, thereby reducing costs and simplifying the structure.

[0038] In one embodiment, such as Figure 3 As shown, the impeller 60 includes a shaft 62, and a plurality of blades 61 are evenly arranged on the outer circumference of the shaft 62; the shaft 62 is connected to and coaxially arranged with the rotating shaft 30; the width direction of the blades 61 is the same as the length direction of the rotating shaft 30. Of course, the blades 61 have an inclination angle, and the specific parameters of the inclination angle can be designed according to the snowmaking parameters. By designing the orientation of the width direction of the blades 61, it can be ensured that the blades 61 can break up ice fragments to generate snowflakes.

[0039] Specifically, the tilt angle of blade 61 refers to the angle between its tilt direction and the cross-section of axle 62. In this embodiment, this angle can be changed according to the user's needs, adjustable from any angle from 0 degrees to 90 degrees. Furthermore, an adjustment device can be added between the blade and axle 62 to facilitate adjustment. By adjusting the angle, the wind pressure and the impact pressure during crushing can be changed, thereby altering the particle size of the artificial snow.

[0040] Moreover, the motor speed can be adjusted by a frequency converter. By coordinating the motor speed and the angle between the blades 61, the torque of the rotation angle can be changed, thereby changing the particle size of the artificial snow and generating artificial snow of different specifications.

[0041] In another embodiment, a protective plate 63 is also provided at the bottom of the impeller 60, and the protective plate 63 is arranged perpendicular to the wheel shaft 62. The protective plate 63 is also connected to the bottom of each blade 61, which can increase the strength of the blade 61 and prevent deformation. On the other hand, when water droplets fall from the flake ice evaporator 10, they can fall onto the protective plate 63. If applied to the top of a shopping mall, this prevents water droplets from falling directly, and instead disperses them around as the impeller 60 rotates, mixing with snowflakes before falling.

[0042] More specifically, the guard plate 63 is a circular plate, and the radius of the guard plate 63 is less than or equal to the sum of the radius of the wheel shaft 62 and the length of the blade 61. This prevents the guard plate 63 from being too large and affecting the rotational balance of the impeller 60.

[0043] In another embodiment, such as Figure 5 As shown, the impeller 60 also includes a retaining ring 64, the inner ring of which is connected to the free end of each blade 61. Specifically, the retaining ring 64 is annular and can be an annular plate, annular rod, etc., and its purpose is to reinforce the blades and increase the stability of the impeller.

[0044] In this embodiment of the invention, the motor 20 is mounted on the top of the flake ice evaporator 10 via a bracket 40. Using the top of the flake ice evaporator 10 as a mounting base allows for better integration of the flake ice evaporator 10 and the crushing mechanism.

[0045] In one embodiment, a guide cylinder 50 is installed on the ice outlet of the flake ice evaporator 10. The guide cylinder 50 is funnel-shaped, with its top opening larger than its bottom opening; the bottom opening of the guide cylinder 50 is located directly above the impeller 60. Since the ice outlet of the flake ice evaporator 10 is usually large, in this embodiment, the guide cylinder 50 is added to its ice outlet to reduce the size of the ice outlet, which can reduce the volume of the crushing mechanism and achieve energy saving.

[0046] As a specific implementation, to avoid mutual interference between the rotating shaft 30 and the main shaft 11 during operation, a gap is provided between the outer circumferential surface of the rotating shaft 30 and the inner circumferential surface of the main shaft 11. More specifically, a bearing is installed between the rotating shaft 30 and the main shaft 11. The bearing can prevent mutual interference between the two and can also form a support between them, preventing the crushing mechanism from swaying left and right, which would affect the snowmaking effect.

[0047] This invention improves the structure of the flake ice evaporator 10, integrating ice-making and snow-making functions into a unified structure. Various components can be installed according to different user needs. During snow making, the number of components required is reduced, significantly decreasing the weight compared to existing equipment, thereby increasing the adjustability of the snow-making mechanism and greatly reducing power consumption.

[0048] The process of using this invention is as follows:

[0049] When ice making is required, the rotating shaft 30 and impeller 60 can be omitted, and the flake ice evaporator 10 can be used directly to make ice.

[0050] When snowmaking is needed, install the rotating shaft 30 and impeller 60. Turn on the flake ice evaporator 10 to make ice. When flake ice falls, turn on the motor 20 to drive the crushing mechanism to break the flake ice into snowflakes. The snowflakes are scattered in all directions by the action of the blades 61 and then slowly fall to form a snow scene.
