[0037] As shown in the following examples, a barrel structure applied to a snow melting machine is provided. Figures 1-6
[0038] Example 1
[0039] A barrel structure applied to a snow melting machine, comprising an outer barrel 100, the inside of the outer barrel 100 inputs refrigerant, liquid is sprayed onto the outer surface of the outer barrel 100 and condenses under the action of the refrigerant, and then is scraped off by a scraper;
[0040] Further comprising,
[0041] The inner barrel 200 is arranged as a cylindrical shell with both ends open and coaxial with the outer barrel 100, and forms an annular refrigeration chamber a with the outer barrel 100;
[0042] The two ends of the inner barrel 200 are arranged in close contact with the outer barrel 100, and are welded and fixed between the inner wall of the outer barrel and the inner wall of the outer barrel, so that the refrigeration chamber a forms a sealed chamber;
[0043] The inner barrel 200 is provided with an air inlet pipe 300 and an air outlet pipe 400 connected to the inside of the refrigeration chamber a, and the refrigeration medium is input into the refrigeration chamber a through the air inlet pipe 300 to cool the two side walls of the refrigeration chamber a.
[0044] The above is the basic scheme of the embodiment.
[0045] Referring to Figure 1 and Figure 2 As shown, the outer barrel 100 is arranged as a shell with at least one end open, the inner barrel 200 is located inside the outer barrel 100 and arranged coaxially with the outer barrel 100, and the outer barrel 100 is welded and fixed with the inner barrel 200.
[0046] For the convenience of welding, in the embodiment, the outer barrel 100 is arranged as a shell with both ends open, the outer walls of the two ends of the inner barrel 200 are welded to the inner walls of the outer barrel 100 respectively, and after the sealing of the refrigeration chamber a is completed, the bottom cover 500 is fixed with the outer barrel 100 or the inner barrel 200 to form a complete cylinder.
[0047] In this way, the airtightness of the refrigeration chamber a can be ensured, thereby avoiding the problem that the refrigeration chamber a is not sealed due to improper assembly or long use time in the prior art, thereby affecting the use effect of the snow melting machine.
[0048] In addition, in the embodiment, the air inlet pipe 300 and the air outlet pipe 400 are arranged to input the refrigeration medium and discharge the internal air, so as to ensure the refrigeration effect of the refrigeration chamber a.
[0049] Preferably, in the embodiment, the two ends of the inner barrel 200 are arranged as fixed ring parts 210, and the fixed ring parts 210 and the main body of the inner barrel 200 are fixed through inclined connecting ring parts 220.
[0050] Referring to Figure 2As shown, in the embodiment, the adapter ring part 220 and the fixed ring part 210 are formed at the two ends of the inner barrel 200 and are integrally formed with the main body. The cross section of the adapter ring part 220 is provided as an inclined surface, that is, the inner diameter of the end adapted to the main body of the inner barrel 200 is smaller than the inner diameter of the end adapted to the fixed ring part 210, so as to satisfy the condition that the diameter of the main body of the inner barrel 200 is smaller than the diameter of the fixed ring part 210, and a stepped structure is formed between the main body of the inner barrel 200 and the fixed ring part 210, so that when the outer wall of the fixed ring part 210 is welded to the outer barrel 100, a gap is left between the outer wall of the main body of the inner barrel 200 and the outer barrel 100, thereby forming the refrigeration chamber a.
[0051] Compared with other assembly methods in the prior art, the welding structure in the embodiment has better sealing performance and does not need to be assembled by using a sealing ring or the like to ensure the sealing performance.
[0052] The refrigeration chamber a is also provided with a liquid guiding member 600, which separates a liquid guiding area and a filling area in the refrigeration chamber a. The air inlet pipe 300 communicates with the liquid guiding area, and the air outlet pipe 400 communicates with the filling area.
[0053] When the air inlet pipe 300 inputs the refrigeration medium into the refrigeration chamber a, the air in the refrigeration chamber a needs to be discharged, so that the refrigeration medium can smoothly enter. Preferably, in the embodiment, the pipe opening of the air inlet pipe 300 is directly arranged in the liquid guiding area, that is, the refrigeration medium is directly input into the liquid guiding area and enters other filling areas of the refrigeration chamber a along the liquid guiding area. Therefore, the pipe opening of the air outlet pipe 400 is arranged in the filling area, and the air is directly discharged from the filling area.
[0054] By arranging the liquid guiding member 600, the flow path of the refrigeration medium in the refrigeration chamber a can be optimized, and the refrigeration efficiency can be improved.
[0055] Embodiment 2
[0056] The embodiment is an improvement based on Embodiment 1, and aims to provide a specific structure of a liquid guiding member, which is mainly applied to a horizontal snow melting machine. The specific implementation manner is as follows:
[0057] The liquid guiding member 600 is provided with at least one liquid guiding groove 601 extending along the axis of the cylinder. The liquid guiding groove 601 is arranged as a recess toward one side of the inner barrel 200, and a gap is left between the groove bottom of the liquid guiding groove 601 and the outer wall of the inner barrel 200.
[0058] The cylinder of the horizontal snow melting machine is in a lying state, that is, the axis of the cylinder is in a horizontal direction. When the refrigeration medium is input, the refrigeration medium flows along the circumference of the cylinder under the action of gravity, so as to fill the entire refrigeration chamber a.
[0059] Specifically refer to Figure 3As shown, in the embodiment, the liquid guide member 600 is arranged along the axial direction of the cylinder body, and the refrigeration medium is input into the liquid guide groove 601 through the air inlet pipe 300, flows along the liquid guide groove 601 first, fills the liquid guide groove 601, and then overflows from the opening side of the liquid guide groove 601. Since the opening side is close to the inner wall of the outer barrel 100, the refrigeration medium first contacts the outer barrel 100, thereby cooling the outer barrel 100 and rapidly refrigerating the outer barrel 100.
[0060] During the filling process of the refrigeration medium, the air inside needs to be discharged, and at the same time, the refrigeration medium needs to uniformly fill the entire refrigeration chamber a. In the embodiment, a gap is left between the groove bottom of the liquid guide groove 601 and the outer wall of the inner barrel 200, so that the refrigeration medium on both sides of the liquid guide groove 601 can pass through, thereby ensuring the uniformity of the refrigeration medium during the filling process.
[0061] To ensure the input position of the refrigeration medium, the liquid guide member 600 needs to be fixed. In the embodiment, at least one deep groove 602 is arranged in the liquid guide groove 601, and the groove bottom of the deep groove 602 is fixed between the outer wall of the inner barrel 200.
[0062] In this way, the liquid guide member 600 is fixed only at the position of the deep groove 602 and the inner barrel 200, and a gap is left between the groove bottom of the liquid guide groove 601 and the inner barrel 200 at other positions, which does not affect the passing of the refrigeration medium.
[0063] The arrangement of the deep groove 602 further optimizes the flow and distribution of the refrigeration medium, which helps to improve the refrigeration effect.
[0064] In the embodiment, to ensure that the refrigeration medium first contacts the outer barrel 100 when overflowing, side wings 610 are arranged on both sides of the liquid guide groove 601, and a plurality of support grooves 611 are arranged on the side wings 610 towards the inner barrel 200.
[0065] When the refrigeration medium overflows from the opening side of the liquid guide groove 601, it first contacts the inner wall of the outer barrel 100 due to the arrangement of the side wings 610, then moves to the outside of the side wings 610 along the side wings 610, and then fills other spaces. In this process, the refrigeration medium always contacts the inner wall of the outer barrel 100, thereby refrigerating the outer barrel 100.
[0066] Specifically refer to Figure 4As shown, since the side wing 610 is a sheet, in order to avoid the refrigeration medium from being extruded, the side wing 610 is pressed to the inner barrel 200 to block the flow of the refrigeration medium on both sides of the liquid guide groove 601. In this embodiment, a support groove 611 is arranged on the side wing 610, the support groove 611 protrudes towards the side of the inner barrel 200, when the support groove 611 is in contact with the outer wall of the inner barrel 200, the liquid still flows through the gap b between the two sides of the support groove 611 and the outer wall of the inner barrel 200, thereby ensuring the space continuity on both sides of the liquid guide groove 601.
[0067] In this embodiment, the liquid guide member 600 is provided with a baffle 700, which can at least receive most of the refrigeration medium input by the air inlet pipe 300.
[0068] With reference to the drawings Figure 5 As shown, when the refrigeration medium is input, due to the large input speed, the refrigeration medium at the pipe opening of the air inlet pipe 300 will present a jet shape, resulting in uneven input of the refrigeration medium. Therefore, a baffle 700 is arranged on the liquid guide member 600 to stop the jet part of the air inlet pipe 300. When the air inlet pipe 300 inputs the refrigeration medium, the refrigeration medium is sprayed onto the baffle 700, thereby effectively controlling the initial flow direction and speed of the refrigeration medium, so that the refrigeration medium enters the liquid guide area more uniformly.
[0069] Embodiment 3
[0070] This embodiment is an improvement based on embodiment 1, and aims to provide another specific structure of the liquid guide member, which is mainly applied to a vertical snow melting machine. The specific implementation manner is:
[0071] The liquid guide member 600 is provided with at least one liquid guide groove 601 extending along the circumference of the cylinder, and the liquid guide groove 601 is provided with a groove wall, and a gap is left between the groove wall and the outer barrel 100.
[0072] With reference to the drawings Figure 6 As shown, the cylinder of the vertical snow melting machine is in a vertical state, and the axis is in a vertical direction. After the refrigeration medium is input, it flows from top to bottom along the axis of the cylinder. Therefore, in this embodiment, the liquid guide member 600 is arranged at the upper part of the refrigeration chamber a, thereby ensuring that the refrigeration medium can fill the entire refrigeration chamber a when it enters.
[0073] Preferably, in this embodiment, the pipe opening position of the air inlet pipe 300 is located inside the liquid guide groove 601 or above the liquid guide groove 601, and a groove wall is arranged below the liquid guide groove 601. The refrigeration medium first fills the liquid guide groove 601, and then overflows in the gap between the groove wall and the outer barrel 100 to flow downward.
[0074] Preferably, in this embodiment, the liquid guide member 600 is arranged in a ring structure with a notch.
[0075] The pipe opening of the air outlet pipe 400 is arranged at the notch position, and the end of the liquid guide groove 601 at the notch position is also provided with a groove wall to avoid the direct filling of the refrigerant to the notch and to block the output of the internal air.
[0076] The liquid guide groove 601 is provided with a baffle, which can at least receive most of the refrigerant input by the air inlet pipe 300.
[0077] When the air inlet pipe 300 inputs the refrigerant, the refrigerant is sprayed onto the baffle, so as to effectively control the initial flow direction and speed of the refrigerant, and make the refrigerant more uniformly enter the liquid guide area.
[0078] The function of the baffle in the embodiment is the same as that in Embodiment 2, and will not be repeated here.
[0079] The above is only a preferred embodiment of the present application, and does not limit the present application in any form. Although the present application has been disclosed as above with a preferred embodiment, it is not intended to limit the present application. Any person skilled in the art can make some changes or modifications to the above disclosed technical content to obtain equivalent embodiments with equivalent changes, without departing from the technical solution of the present application.
