This process is complex and costly. Furthermore, the evaporator only contacts the liquid on one side, resulting in low refrigeration efficiency, high operating losses, and insufficient utilization of the refrigerant. The uneven cooling on one side also affects the refrigeration effect. Utility Model Content

[0010] As a preferred embodiment of this utility model, the connecting hole is located at the side end of the evaporator cylinder, slightly higher than the partition plate.

[0011] As a preferred embodiment of this utility model, the top of the inner stirring blade is fixedly connected to the outer stirring blade, and the outer stirring blade is also equipped with a connecting frame that is rotatably connected to the outside of the evaporation cylinder.

[0013] As a preferred embodiment of this utility model, an installation ring is installed at the bottom of the evaporator, and a refrigeration cylinder is installed in the snow melting machine body. The evaporator is installed in the refrigeration cylinder through the installation ring.

[0014] Compared with the prior art, this utility model provides a high-efficiency evaporator for a snow melting machine, which has the following beneficial effects:

[0015] 1.

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example 1

[0026] Please see the appendix Figure 1-7 This utility model discloses a high-efficiency evaporator for a snow melting machine, including a snow melting machine body 4 and an evaporation cylinder 1 installed inside the snow melting machine, and also includes a stirring assembly 2, wherein:

[0027] The evaporator cylinder 1 is open at both ends, and the cylinder body of the evaporator cylinder 1 is provided with a fully enclosed and annular evaporation chamber 12. The side end of the evaporator cylinder 1 is provided with a connecting hole 3 that penetrates the cylinder wall of the evaporator cylinder 1.

[0028] The stirring assembly 2 includes an inner stirring blade 22 and an outer stirring blade 21 that are rotatably connected to the inner and outer sides of the evaporation cylinder 1, respectively.

[0029] The bottom of the inner wall of the evaporator cylinder 1 is equipped with a refrigerant inlet pipe 13 and a refrigerant outlet pipe 14, which are connected to the evaporation chamber 12.

[0030] Please refer to the appendix. Figure 3 , Figure 4 The inner stirring blade 22 is equipped with a power shaft 23 that is coaxial with the evaporator 1. The inner wall of the evaporator 1 near the bottom is equipped with a partition plate 11. A mechanical seal 25 is installed at the connection between the power shaft 23 and the partition plate 11.

[0031] Specifically, the power shaft 23 is connected to the motor in the snow melting machine to drive the inner stirring blades 22, so that the inner stirring blades 22 stir the liquid in the evaporation cylinder 1, making the cooling effect of the liquid in the evaporation cylinder 1 more uniform, and the partition plate 11 and the mechanical seal 25 can prevent liquid from seeping and leaking to the motor.

[0032] Furthermore, the connection hole 3 is located at the side end of the evaporator cylinder 1, slightly higher than the partition plate 11.

[0033] Furthermore, the top of the inner stirring blade 22 is fixedly connected to the outer stirring blade 21, and the outer stirring blade 21 is also equipped with a connecting frame 24 that is rotatably connected to the outside of the evaporation cylinder 1.

[0034] Specifically, when the inner stirring blade 22 rotates under the drive of the power shaft 23, it can simultaneously drive the outer stirring blade 21 to rotate and stir, stirring the liquid on the outer wall of the evaporator 1, so that the cooling effect of the liquid in contact with the outside of the evaporator 1 is more uniform.

[0035] Please refer to the appendix. Figure 6 , Figure 7 An installation ring 15 is installed at the bottom of the evaporator cylinder 1, and a refrigeration cylinder 41 is installed in the snow melting machine body 4. The evaporator cylinder 1 is installed in the refrigeration cylinder 41 through the installation ring 15. Example 2

[0036] Based on the above embodiment one, please refer to the appendix. Figure 5 The connection hole 3 is provided in multiple ways, preferably two, and the two connection holes 3 are located at the same height and are symmetrically arranged on the outer wall of the evaporator cylinder 1.

[0037] In this embodiment, by increasing the number of connection holes 3, the circulation speed of the liquid inside and outside the evaporator 1 can be accelerated during refrigeration, thereby improving the refrigeration effect.

[0038] The working principle and usage process of this utility model are as follows: The refrigerant enters the evaporation chamber 12 from the refrigerant inlet pipe 13 and evaporates on one side, releasing into the entire evaporation chamber 12 for cooling. The liquid in the refrigeration cylinder 41 of the snow melting machine enters the evaporation cylinder 1 from the connection hole 3. At this time, the liquid on the inner and outer sides of the evaporation cylinder 1 contacts the inner and outer walls of the evaporation cylinder 1 for cooling. During the cooling process, the motor connected to the power shaft 23 in the snow melting machine starts and drives the power shaft 23 to rotate. The power shaft 23 drives the inner stirring blade 22 and the outer stirring blade 21 to stir and homogenize the liquid on the inner and outer sides of the evaporation cylinder 1 to achieve the cooling effect. The gaseous refrigerant after evaporation and cooling is extracted from the refrigerant outlet pipe, completing the cooling process.
