Description

Technical Field

[0001] This utility model relates to the field of evaporator technology, and in particular to a sealed evaporator and a snow ice machine. Background Technology

[0002] A shaved ice machine is a device used to rapidly freeze liquid materials into ice and scrape the ice into shaved ice that can be eaten immediately. Current shaved ice machines generally include a refrigeration unit and a snow-making unit. The snow-making unit includes a cylindrical evaporator that freezes the liquid materials dripping onto its outer wall. One end of the evaporator is connected to a pipe for refrigerant input and output. Currently, the internal sealing of the evaporator typically uses O-rings for axial sealing. When the cylindrical evaporator is stationary, the O-rings provide a good seal. However, when the evaporator rotates, there is relative movement between the evaporator and the sealing ring, and the high pressure inside the evaporator reduces the sealing effectiveness of the O-rings, potentially causing refrigerant leakage and affecting the refrigeration effect. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a sealed evaporator and a snow ice machine, which can improve the internal sealing effect of the evaporator, ensure that there is no refrigerant liquid leakage during the operation of the evaporator cylinder, and improve the refrigeration effect.

[0004] To solve the above-mentioned technical problems, this utility model provides a sealed evaporator, including an evaporator cylinder and a refrigerant pipe. A rotating part of the evaporator cylinder is embedded with the refrigerant pipe, and the two enclose a sealed mounting cavity. The refrigerant pipe communicates with the inner cavity of the evaporator cylinder. The sealed mounting cavity is provided with at least one sealing ring and at least two Glyd rings. The sealing ring and the Glyd ring are nested on the refrigerant pipe at intervals and are arranged sequentially from the inside to the outside along the axial direction of the evaporator cylinder. The sealing ring is close to the inner cavity of the evaporator cylinder.

[0005] As an improvement to the above solution, the sealing mounting cavity includes a first sealing mounting cavity and a second sealing mounting cavity spaced apart. The first sealing mounting cavity is provided with the sealing ring, and the second sealing mounting cavity is provided with the Gladger ring. A spacer ring is provided between two adjacent Gladger rings.

[0006] As an improvement to the above solution, a hollow mounting groove is provided at one end of the rotating shaft away from the inner cavity of the evaporator cylinder, and a bearing assembly is installed in the mounting groove. The bearing assembly is nested on the refrigerant pipe; the rotating shaft, the bearing assembly and the refrigerant pipe together form the sealed mounting cavity.

[0007] As an improvement to the above solution, the Glad ring includes a rubber ring and a sealing ring. The sealing ring is nested on the refrigerant pipe, and the rubber ring is nested on the sealing ring. The two ends of the rubber ring abut against the inner wall of the second sealing installation cavity and the sealing ring, respectively.

[0008] As an improvement to the above solution, the sealing ring is provided with an abutment end and a sealing end at both ends. The abutment end is provided with an annular mounting groove, which abuts against the rubber ring. The sealing end is sealed to the outer surface of the refrigerant pipe.

[0009] As an improvement to the above solution, the sealing end is provided with multiple annular grooves at intervals.

[0010] As an improvement to the above solution, the bearing assembly includes a bearing and an isolating ring, the isolating ring being mounted on the mounting groove and abutting against the nearest Glyd ring; a limiting protrusion is provided at one end of the refrigerant pipe away from the inner cavity of the evaporator cylinder, and the bearing abuts against the limiting protrusion and the isolating ring respectively.

[0011] As an improvement to the above solution, a hollow limiting installation groove is provided at one end of the rotating shaft away from the inner cavity of the evaporator cylinder. The limiting installation groove is located on the outside of the installation groove, and a retaining ring is provided in the limiting installation groove.

[0014] The beneficial effects of implementing this utility model are as follows:

[0015] The present invention provides a sealed mounting cavity between the evaporator shell and the refrigerant pipe. The sealed mounting cavity contains a sealing ring and a Glyd ring arranged in sequence. The sealing ring can withstand most of the internal pressure and play a preliminary sealing role.

[0020] To make the objectives, technical solutions and advantages of this utility model clearer, the utility model will be described in further detail below with reference to the accompanying drawings.

[0021] like Figures 1 to 2 As shown in the figure, a specific embodiment of this utility model provides a sealed evaporator, including an evaporator cylinder 1 and a refrigerant pipe 2. A rotating shaft 11 of the evaporator cylinder 1 is embedded with the refrigerant pipe 2, and the two enclose a sealed mounting cavity 3. The refrigerant pipe 2 communicates with the inner cavity of the evaporator cylinder 1. The refrigerant in the condenser can enter the evaporator cylinder 1 through the refrigerant pipe 2, so that the evaporator cylinder 1 can perform heat exchange and ice making. The refrigerant after heat exchange also returns to the compressor through the refrigerant pipe 2.

[0022] The sealed mounting cavity 3 is provided with at least one sealing ring 4 and at least two Glyd rings 5. The sealing ring 4 and the Glyd ring 5 are nested on the refrigerant pipe 2 at intervals, which can prevent the sealing ring 4 and the Glyd ring 5 from contacting or rubbing against each other, thus affecting the sealing effect. Moreover, the sealing ring 4 and the Glyd ring 5 are arranged sequentially from the inside to the outside along the axial direction of the evaporator cylinder 1, with the sealing ring 4 close to the inner cavity of the evaporator cylinder 1. When the evaporator cylinder 1 rotates to make ice or is running, the internal pressure of the evaporator cylinder 1 first acts on the sealing ring 4. The sealing ring 4 can withstand most of the internal pressure and play a first-level sealing role. When the internal pressure rises or is too high, the sealing connection effect of the sealing ring 4, which rotates relative to the evaporator cylinder 1, will weaken. Some of the internal pressure acts on multiple Glyd rings 5 ​​after passing through the first-level sealing ring 4. When there is no internal pressure, the Glyd ring 5 can fit tightly between the rotating shaft 11 and the refrigerant pipe 2. When the Glyd ring 5 is deformed by pressure, it can fit even more tightly between the rotating shaft 11 and the refrigerant pipe 2, playing a second-level sealing role and maintaining the internal sealing effect of the evaporator. The sealing effect can be further improved by multiple Glyd rings 5, ensuring that there is no refrigerant liquid leakage when the evaporator cylinder 1 is running, and improving the refrigeration effect.

[0023] Specifically, such as Figures 1 to 2As shown, the sealing mounting cavity 3 includes a first sealing mounting cavity 31 and a second sealing mounting cavity 32 spaced apart. The first sealing mounting cavity 31 contains one sealing ring 4, and the second sealing mounting cavity 32 contains two Glyd rings 5, forming a first and second sealing area respectively, thereby improving the sealing effect. A spacer ring 6 is provided between adjacent Glyd rings 5 ​​to further separate the sealing rings 4 and Glyd rings 5, preventing contact or friction between the rings and affecting the sealing effect. In other embodiments, the spacer ring 6 can also be provided for multiple sealing rings 4 to separate them and improve the sealing effect. The sealing ring 4 is a conventional O-ring.

[0024] Furthermore, the Gladius ring 5 includes a rubber ring 51 and a sealing ring 52. The sealing ring 52 is nested on the refrigerant pipe 2, and the rubber ring 51 is nested on the sealing ring 52. The two ends of the rubber ring 51 abut against the inner wall of the second sealing mounting cavity 32 and the sealing ring 52, respectively. In the initial state, one end of the rubber ring 51 presses against the sealing ring 52, causing the sealing ring 52 to adhere to the refrigerant pipe 2, forming a sealed connection between the sealing ring 52 and the refrigerant pipe 2. The other end of the rubber ring 51 abuts tightly against the inner wall of the second sealing mounting cavity 32, forming a sealed connection between the rubber ring 51 and the rotating shaft 11. Thus, the sealing between the rotating shaft 11 and the refrigerant pipe 2 is achieved through the Glyd ring 5. When there is internal pressure in the evaporator, the rubber ring 51 deforms under pressure and abuts even more tightly against the inner wall of the second sealing mounting cavity 32, further pressing the sealing ring 52, making the sealing ring 52 even more tightly fitted to the refrigerant pipe 2, thereby maintaining the internal sealing effect of the evaporator and ensuring that there is no refrigerant liquid leakage when the evaporator cylinder 1 is running, thus improving the refrigeration effect.

[0025] The sealing ring 52 has an abutment end 521 and a sealing end 522 at its two ends. The abutment end 521 has an annular mounting groove 523, which abuts against the rubber ring 51. The sealing end 522 is sealed to the outer surface of the refrigerant pipe 2. The annular mounting groove 523 allows the rubber ring 51 to apply more force to the sealing ring 52, improving the sealing effect of the sealing ring 52.

[0026] Preferably, the sealing end 522 is provided with a plurality of annular grooves 524 at intervals, thereby increasing the amount of compression deformation, improving the sealing performance, and reducing the contact wear area, thus extending its service life.

[0027] like Figures 1 to 2As shown, a hollow mounting groove 12 is provided at one end of the rotating shaft 11 away from the inner cavity of the evaporator cylinder 1. A bearing 71 assembly 7 is installed in the mounting groove 12. The bearing 71 assembly 7 is nested on the refrigerant pipe 2, which can reduce the friction loss of the evaporator cylinder 1 during rotation and guide the rotation of the evaporator cylinder 1. The rotating shaft 11, the bearing 71 assembly 7, and the refrigerant pipe 2 enclose and form the sealed mounting cavity 3. The bearing 71 assembly 7 can prevent external debris from entering the sealed mounting cavity 3 and prevent the internal lubricant from leaking out, ensuring the normal operation of the bearing 71 and the evaporator cylinder 1.

[0028] The bearing assembly 71 includes a bearing 71 and an isolating ring 72. The isolating ring 72 is installed on the mounting groove 12 and abuts against the nearest Glyd ring 5 to separate the Glyd ring 5 and the bearing 71 and avoid unnecessary friction. The end of the refrigerant pipe 2 away from the inner cavity of the evaporator cylinder 1 is provided with a limiting protrusion ring 21. The bearing 71 abuts against the limiting protrusion ring 21 and the isolating ring 72 respectively to limit and fix the bearing 71 and the various components in the second sealed mounting cavity 32.

[0029] To further improve the limiting effect of bearing 71, such as Figures 2 to 3 As shown, a hollow limiting installation groove 13 is provided at one end of the rotating shaft away from the inner cavity of the evaporator cylinder 1. The limiting installation groove 13 is located outside the installation groove 12. A retaining ring 73 is provided in the limiting installation groove 13. The retaining ring 73 and the limiting convex ring 21 abut against the same end face of the bearing 71 to further improve the limiting effect of the bearing 71, thereby restricting the axial movement of the bearing 71 and its inner components and ensuring the stable operation of each component.

[0030] To improve the installation stability of refrigerant pipe 2, such as Figures 2 to 3 As shown, the refrigerant pipe 2 is provided with a fixing groove 22 on the outside of the limiting protrusion ring 21. The fixing groove 22 is provided with a positioning baffle 23. One end of the positioning baffle 23 is engaged with the fixing groove 22, and the other end is fixedly set on the external body 8, thereby fixing the refrigerant pipe 2, improving its installation firmness, and thus limiting the bearing 71 and the entire evaporator cylinder 1.

[0031] like Figure 4 As shown in the figure, a specific embodiment of this utility model also provides a shaved ice machine, including a body 8, wherein the body 8 is provided with an evaporator mounting cavity 81, and the evaporator mounting cavity 81 is provided with the aforementioned sealed evaporator 9. Since the aforementioned sealed evaporator 9 has the above-mentioned technical effects, the shaved ice machine including the sealed evaporator 9 should also have the above-mentioned technical effects, and will not be described in detail here.

[0032] In summary, the present invention provides a sealed mounting cavity between the evaporator shell and the refrigerant pipe. The sealed mounting cavity contains a sealing ring and a Glyd ring arranged in sequence. The sealing ring can withstand most of the internal pressure and provide a preliminary seal, while the Glyd ring can maintain the internal sealing effect of the evaporator regardless of whether there is internal pressure. This ensures that there will be no refrigerant leakage when the evaporator shell is running, thereby improving the refrigeration effect.

[0033] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications are also considered to be within the protection scope of this utility model.
