[0039] When the gas injection partition plate is integrally cast and processed, the gas injection volute is located inside the gas injection partition plate, and the size of the gas injection port is small, making it difficult to clean the sand inside the gas injection partition plate, resulting in casting defects and poor forming of the gas injection volute, and reducing the surface finish of the gas injection volute.

[0040] In view of this, as shown in Figures 1 to 6 The gas injection partition plate assembly 100 includes a first partition plate 10 and a second partition plate 20. The surface of one side of the first partition plate 10 is provided with a gas guide groove 11. The second partition plate 20 is arranged on one side of the first partition plate 10. The surface of one side of the second partition plate 20 facing the first partition plate 10 is provided with an annular groove 21. The annular groove 21 corresponds to the position of the gas guide groove 11. Wherein, the gas guide groove 11 and the annular groove 21 form a gas injection volute 30.

[0041] In the embodiment, the gas injection partition plate assembly 100 includes a first partition plate 10 and a second partition plate 20, and the second partition plate 20 is arranged on one side of the first partition plate 10. That is, the gas injection partition plate assembly 100 is a split structure composed of the first partition plate 10 and the second partition plate 20, which is convenient for structure processing.

[0042] In this embodiment, the surface of one side of the first partition plate 10 is provided with the air guide groove 11, and the surface of one side of the second partition plate 20 facing the first partition plate 10 is provided with the annular groove 21. That is, on the opposite sides of the first partition plate 10 and the second partition plate 20, the surface of the first partition plate 10 is provided with the air guide groove 11, and the surface of the second partition plate 20 is provided with the annular groove 21, which facilitates the processing of the air guide groove 11 and the annular groove 21 and helps to improve the surface finish of the air guide groove 11 and the annular groove 21. The annular groove 21 corresponds to the position of the air guide groove 11, so that the air guide groove 11 and the annular groove 21 can be enclosed to form the air charging volute 30, which improves the surface finish of the air charging volute 30 and reduces the flow loss of the gas flow inside the air charging volute 30.

[0043] Compared with the integral structure of the air charging partition plate in the related art, the air charging partition plate assembly 100 in this embodiment is a split structure composed of the first partition plate 10 and the second partition plate 20. The air guide groove 11 is located on the surface of the first partition plate 10, and the annular groove 21 is located on the surface of the second partition plate 20, which facilitates the processing by means other than casting and helps to improve the surface finish of the air charging volute 30. It can be understood that the specific processing method of the air charging partition plate assembly 100 in this embodiment is not limited.

[0044] For example, the air charging partition plate assembly 100 is a split structure composed of the first partition plate 10 and the second partition plate 20. In actual processing, the first partition plate 10 and the second partition plate 20 can be processed by machining, which can improve the controllability of the shape of the air guide groove 11 and the annular groove 21, thereby improving the formability controllability of the air charging volute 30 and improving the surface finish of the air guide groove 11 and the annular groove 21. In this example, the air guide groove 11 and the annular groove 21 can be further processed by mechanical finishing to improve the surface finish of the air guide groove 11 and the annular groove 21, thereby improving the surface finish of the air charging volute 30 and effectively reducing the flow loss of the gas flow inside the air charging volute 30, and the processing is convenient.

[0045] In actual application, the air charging partition plate assembly 100 can be applied to a compressor to guide and control the flow of gas in the compressor. The specific installation position of the air charging partition plate assembly 100 in the compressor is not limited. For example, the air charging partition plate assembly 100 can be used as an air inlet partition plate of the compressor to guide the gas to the inlet of the impeller.

[0046] It can be understood that the specific shape of the first partition plate 10 and the second partition plate 20 is not limited and can be adjusted as required according to the installation and use environment. For example, a circular shape.

[0047] In some embodiments, as Figure 1 and Figures 3 to 6As shown, the first partition 10 includes a first annular mating portion 12. The first annular mating portion 12 surrounds the outside of the air guide groove 11. The second partition 20 includes a first annular protrusion 22 and a second annular protrusion 23. The first annular protrusion 22 is located at the outer circle of the annular groove 21. The first annular protrusion 22 is provided with a second annular mating portion 27 that mates with the first annular mating portion 12. The second annular protrusion 23 is located at the inner circle of the annular groove 21. Wherein, when the first annular mating portion 12 and the second annular mating portion 27 are mated, there is a gap between the second annular protrusion 23 and the first partition 10.

[0048] In this embodiment, the first partition 10 includes a first annular mating portion 12, which surrounds the outside of the air guide groove 11. That is, the air guide groove 11 is located on the side of the first annular mating portion 12 near the middle of the first partition 10.

[0049] In this embodiment, the second partition 20 includes a first annular protrusion 22 and a second annular protrusion 23, the first annular protrusion 22 being located at the outer circumference of the annular groove 21 (e.g., Figure 5 (e in the image), the second annular protrusion 23 is located at the inner circle of the annular groove 21 (as shown in the image). Figure 5 (at point f in the text). That is, the first annular protrusion 22 and the second annular protrusion 23 are located on opposite sides of the annular groove 21, with the first annular protrusion 22 near the edge of the second partition 20 and the second annular protrusion 23 near the middle of the second partition 20. The first annular protrusion 22 and the second annular protrusion 23 define the annular groove 21.

[0050] In this embodiment, the first annular protrusion 22 is provided with a second annular mating portion 27 that mates with the first annular mating portion 12. That is, on the opposite sides of the first partition 10 and the second partition 20, the first annular protrusion 22 corresponds to the position of the first annular mating portion 12, and the first annular protrusion 22 is provided with a second annular mating portion 27 that can mate with the first annular mating portion 12. Through the mating connection of the first annular mating portion 12 and the second annular mating portion 27, the positioning and connection between the first partition 10 and the second partition 20 are achieved, thereby allowing the air guide groove 11 and the annular groove 21 to enclose and form the gas filling chamber 30. When the first annular mating portion 12 and the second annular mating portion 27 are mated, a gap exists between the second annular protrusion 23 and the first partition 10, allowing gas in the gas filling chamber 30 to flow out through this gap.

[0051] In practical applications, after the first annular mating part 12 and the second annular mating part 27 are engaged, the first partition 10 and the second partition 20 can be fixedly connected, facilitating the installation of the gas filling partition assembly 100. The specific method of fixing the first partition 10 and the second partition 20 is not limited, such as welding or bolt connection.

[0052] In some embodiments, as shown in Figure 1 , Figure 3 and Figure 4 , the gas injection baffle assembly 100 further comprises a plurality of guide vanes 40. The length direction of the guide vanes 40 extends along the radial direction of the first baffle 10. The plurality of guide vanes 40 are arranged in sequence and are located in the gap between the second annular protrusion 23 and the first baffle 10.

[0053] In this embodiment, the gas injection baffle assembly 100 further comprises a plurality of guide vanes 40, the length direction of the guide vanes 40 extends along the radial direction of the first baffle 10, so that the guide vanes 40 can adjust the flow angle of the gas flow. The plurality of guide vanes 40 are arranged in sequence and are located in the gap between the second annular protrusion 23 and the first baffle 10. That is, when the gas in the gas injection volute 30 flows out from the gap between the second annular protrusion 23 and the first baffle 10, the plurality of guide vanes 40 can adjust the flow angle of the gas flow, reduce the impact loss of the upstream gas, realize uniform mixing with the upstream gas, and improve the gas injection efficiency. When applied to a compressor, the overall performance of the unit can be improved.

[0054] Optionally, the plurality of guide vanes 40 are arranged on the first baffle 10 and / or the second baffle 20. When the guide vanes 40 are arranged on the first baffle 10, the guide vanes 40 are located on the surface of the first baffle 10 on the side facing the second annular protrusion 23. When the guide vanes 40 are arranged on the second baffle 20, the guide vanes 40 are located on the surface of the second annular protrusion 23 on the side facing the first baffle 10.

[0055] In this embodiment, the plurality of guide vanes 40 are arranged on the first baffle 10 and / or the second baffle 20. That is, as shown in Figure 3 , the plurality of guide vanes 40 are arranged on the first baffle 10. Alternatively, the plurality of guide vanes 40 are arranged on the second baffle 20. Alternatively, the plurality of guide vanes 40 are arranged in two parts, one part of the guide vanes 40 is arranged on the first baffle 10, and the other part of the guide vanes 40 is arranged on the second baffle 20. Moreover, when the first annular fitting part 12 and the second annular fitting part 27 are fitted, the plurality of guide vanes 40 are arranged in sequence and are located in the gap between the second annular protrusion 23 and the first baffle 10, so as to adjust the flow angle of the gas flow.

[0056] Optionally, as shown in Figure 1 , Figure 3 and Figure 4 , the plurality of guide vanes 40 are arranged in sequence and uniformly, so as to improve the uniformity of the gas guide.

[0057] Optionally, as shown in Figure 1 , Figure 3 and Figure 4 , the plurality of guide vanes 40 are arranged in sequence and uniformly, so as to improve the uniformity of the gas guide.As shown, the plurality of guide vanes 40 are arranged in a ring shape in sequence and at intervals, so that the plurality of guide vanes 40 are located in the gap between the second annular protrusion 23 and the first partition plate 10, improving the uniformity of air guiding.

[0058] It can be understood that the shape of the guide vanes 40 is not limited and can be designed as needed.

[0059] In some embodiments, as shown in Figure 1 , Figure 4 and Figure 6 , the first annular fitting part 12 and the second annular fitting part 27 are fitted in a way of a stop opening.

[0060] In this embodiment, the first annular fitting part 12 and the second annular fitting part 27 are fitted in a way of a stop opening, so that the first partition plate 10 and the second partition plate 20 are spliced to form the gas injection partition plate assembly 100, and the air guiding groove 11 and the annular groove 21 are enclosed to form the gas injection volute 30.

[0061] It can be understood that the specific structure of the first annular fitting part 12 and the second annular fitting part 27 is not limited, and the first annular fitting part 12 and the second annular fitting part 27 can be fitted in a way of a stop opening. For example, the first annular fitting part 12 is one of a convex stop opening and a concave stop opening, and the second annular fitting part 27 is the other one of a convex stop opening and a concave stop opening.

[0062] In some embodiments, as shown in Figures 2 to 6 , the gas injection partition plate assembly 100 further comprises an air inlet 31. The air inlet 31 is arranged on the first partition plate 10 and / or the second partition plate 20, and the air inlet 31 is in communication with the gas injection volute 30, so that external gas enters the gas injection volute 30 through the air inlet 31.

[0063] In this embodiment, the gas injection partition plate assembly 100 further comprises an air inlet 31, and the air inlet 31 is in communication with the gas injection volute 30, so that external gas enters the gas injection volute 30 through the air inlet 31, that is, the gas outside the gas injection partition plate assembly 100 enters the gas injection volute 30 through the air inlet 31, so as to guide and mix the gas.

[0064] In this embodiment, the air inlet 31 is arranged on the first partition plate 10 and / or the second partition plate 20. That is, the air inlet 31 is arranged on the first partition plate 10. Alternatively, the air inlet 31 is arranged on the second partition plate 20. Alternatively, the air inlet 31 is arranged on the first partition plate 10 and the second partition plate 20.

[0065] Optionally, as shown in Figures 2 to 6As shown, when the air inlet 31 is disposed on the first partition 10 and the second partition 20, the air inlet 31 is located at the junction of the first partition 10 and the second partition 20. That is, a part of the structure of the air inlet 31 is located on the first partition 10, and another part of the air inlet 31 is located on the second partition 20. When the first partition 10 and the second partition 20 are spliced ​​together, a part and another part of the air inlet 31 form the air inlet 31, so that the gas outside the gas filling partition assembly 100 enters the gas filling volute 30 through the air inlet 31.

[0066] In some embodiments, such as Figure 1 , Figure 5 and Figure 6 As shown, the refueling baffle assembly 100 also includes a flow divider 24. The flow divider 24 is disposed within the annular groove 21 and located on the side away from the air inlet 31. The flow divider 24 is intersecting with the second baffle 20. Wherein, when the air guide groove 11 and the annular groove 21 enclose the refueling volute 30, the flow divider 24 can divide the refueling volute 30 into two parts.

[0067] In this embodiment, the flow divider 24 is disposed within the annular groove 21 and located on the side away from the air inlet 31. Gas entering the gas filling chamber 30 through the air inlet 31 flows along the inner wall of the gas filling chamber 30 towards the flow divider 24. When the gas flows to the flow divider 24, the flow divider 24 can change the direction and speed of the gas flow. Specifically, Figure 3 and Figure 5 The dashed arrows in the diagram indicate the flow direction of gas after it enters the gas filling chamber 30 from the inlet 31. For example... Figure 5 As shown, the gas entering the gas filling chamber 30 through the air inlet 31 can flow to the flow divider 24 in both left and right directions. The flow divider 24 can change the flow direction and speed of the gas and improve the stability of the gas flow.

[0068] In this embodiment, the flow divider 24 is disposed within the annular groove 21, and the flow divider 24 intersects with the second partition 20. That is, as... Figure 5 As shown, the flow divider 24 protrudes from the second partition 20 to divide the annular groove 21 into left and right parts. Therefore, when the air guide groove 11 and the annular groove 21 form the air filling chamber 30, the flow divider 24 can divide the air filling chamber 30 into left and right parts. In practical applications, such as... Figure 5 As shown, the gas entering the gas filling volute 30 through the air inlet 31 flows towards the flow divider 24 from both the left and right sides, and changes the direction and speed of the flow at the flow divider 24 so that the gas can flow out of the gas filling volute 30 smoothly, improve the stability of the gas flow, and thus improve the gas guiding effect of the gas filling baffle assembly 100.

[0069] In some embodiments, such as Figure 1 , Figure 5 andFigure 6 As shown, the air filling baffle assembly 100 also includes a first baffle plate 25 and / or a second baffle plate 26. The first baffle plate 25 is disposed on one side of the flow divider 24. One end of the first baffle plate 25 is connected to the flow divider 24, and the other end of the first baffle plate 25 is connected to the groove wall of the annular groove 21. The second baffle plate 26 is disposed on the other side of the flow divider 24. One end of the second baffle plate 26 is connected to the flow divider 24, and the other end of the second baffle plate 26 is connected to the groove wall of the annular groove 21. Both the first baffle plate 25 and the second baffle plate 26 protrude in a direction away from the air inlet 31.

[0070] In this embodiment, the gas filling baffle assembly 100 further includes a first brow plate 25 and / or a second brow plate 26. That is, the gas filling baffle assembly 100 further includes a first brow plate 25. Alternatively, the gas filling baffle assembly 100 further includes a second brow plate 26. Alternatively, the gas filling baffle assembly 100 further includes a first brow plate 25 and a second brow plate 26.

[0071] In this embodiment, Figure 3 and Figure 5 The dashed arrows in the diagram indicate the flow direction of gas after it enters the gas filling chamber 30 from the inlet 31. The first eyebrow plate 25 is located on one side of the flow divider 24, and the second eyebrow plate 26 is located on the other side of the flow divider 24. Specifically, as shown... Figure 5 As shown, the first eyebrow plate 25 is located on the left side of the flow divider plate 24, and the second eyebrow plate 26 is located on the right side of the flow divider plate 24. That is, the first eyebrow plate 25 and the second eyebrow plate 26 are located on opposite sides of the flow divider plate 24. One end of the first eyebrow plate 25 is connected to the flow divider plate 24, and the other end is connected to the wall of the annular groove 21. The first eyebrow plate 25 guides the gas in the annular groove 21 to the flow divider plate 24, providing stable guidance for the gas flow. One end of the second eyebrow plate 26 is connected to the flow divider plate 24, and the other end is connected to the wall of the annular groove 21. The second eyebrow plate 26 also guides the gas in the annular groove 21 to the flow divider plate 24, providing stable guidance for the gas flow. Both the first eyebrow plate 25 and the second eyebrow plate 26 protrude in a direction away from the air inlet 31. That is to say, both the first eyebrow plate 25 and the second eyebrow plate 26 are arc-shaped plate structures, with the protruding part in the middle of the arc-shaped plate structure facing away from the air inlet 31, so that the gas in the annular groove 21 can flow smoothly to the diverter plate 24 through the first eyebrow plate 25 and the second eyebrow plate 26, thereby realizing the regulation of the gas flow direction and speed.

[0072] When the gas filling baffle assembly 100 of this embodiment is applied to the compressor 200, the flow direction and speed of the gas can be adjusted through the flow divider 24, the first baffle 25 and the second baffle 26, which helps to distribute the airflow evenly to the impeller and improve the efficiency and stability of the compressor 200.

[0074] Optionally, as shown in Figure 5 As shown, the one end of the second brow plate 26 away from the shunt plate 24 is tangentially connected with the groove wall of the annular groove 21, that is, the connection between the one end of the second brow plate 26 away from the shunt plate 24 and the groove wall of the annular groove 21 is smoothly transitioned, so that the gas in the annular groove 21 can smoothly flow to the shunt plate 24 through the second brow plate 26.

[0075] In some embodiments, as shown in Figure 1 , Figures 3 to 6 The gas injection baffle assembly 100 further comprises a gas outlet hole 32. The gas outlet hole 32 penetrates the middle part of the first baffle 10 and the second baffle 20. The gas outlet hole 32 extends along the axial direction of the first baffle 10 and the second baffle 20. The gas outlet hole 32 is in communication with the gas injection volute 30. The gas in the gas injection volute 30 can be discharged through the gas outlet hole 32.

[0076] In this embodiment, the gas outlet hole 32 is in communication with the gas injection volute 30, so that the gas in the gas injection volute 30 can be discharged through the gas outlet hole 32. The gas injection volute 30 of this embodiment is formed by the gas guide groove 11 located on the first baffle 10 and the annular groove 21 located on the second baffle 20. The gas outlet hole 32 penetrates the middle part of the first baffle 10 and the second baffle 20, and extends along the axial direction of the first baffle 10 and the second baffle 20, so as to realize the communication between the gas outlet hole 32 and the gas injection volute 30, and smoothly discharge the gas in the gas injection volute 30.

[0077] In some embodiments, as shown in Figure 1 , Figure 3 and Figure 4 The groove wall of the gas guide groove 11 close to the gas outlet hole 32 is inclined to extend to the gas outlet hole 32, so as to guide the gas in the gas injection volute 30 to the gas outlet hole 32.

[0078] In this embodiment, Figure 1 , Figure 3 and Figure 4 a in the above formula is used to indicate the groove wall of the gas guide groove 11 close to the gas outlet hole 32. The groove wall of the gas guide groove 11 close to the gas outlet hole 32 is inclined to extend to the gas outlet hole 32, specifically, as shown in Figure 1As shown, the groove wall of the gas guide groove 11 close to the gas outlet hole 32 is inclined towards the second baffle 20. That is, in the radial direction of the first baffle 10, as the groove wall of the gas guide groove 11 close to the gas outlet hole 32 gradually extends towards the axis of the first baffle 10, the distance between the groove wall and the second baffle 20 gradually decreases, improving the gas guiding effect of the gas guide groove 11 to smoothly guide the gas in the gas charging volute 30 to the gas outlet hole 32, thereby achieving smooth delivery of the gas in the gas charging volute 30.

[0079] As shown, Figures 1 to 7 The present disclosure also provides a compressor 200. The compressor 200 includes a compressor body and the gas charging baffle assembly 100 according to any one of the preceding embodiments. The compressor body includes a cylinder 201.
