DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the utility model are described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] This embodiment provides a vacuum high-efficiency steam-water separator, which is mainly used to improve the effect of water vapor separation.

[0025] like Figure 1 As shown, it includes a cylinder 1, wherein the side wall of the cylinder 1 is provided with an air inlet 11 and an air outlet 12 connected to the inner cavity of the cylinder 1, as shown in FIG. Figure 2 As shown, it also includes a partition plate 21 that divides the inner cavity of the cylinder 1 into a first inner cavity 101 and a second inner cavity 102. Specifically, the first inner cavity 101 is located on the upper side of the partition plate 21, and the second inner cavity 102 is located on the lower side of the partition plate 21. The air inlet 11 is connected to the second inner cavity 102, and the air outlet 12 is connected to the first inner cavity 101.

[0026] Under normal circumstances, in order to improve the gas-water separation effect, such as Figure 2 As shown, a vertically arranged inner cylinder 22 is also provided in the inner cavity of the cylinder body 1, wherein the inner cylinder 22 is fixedly mounted on the bottom wall of the partition plate 21, the chamber of the inner cylinder 22 connects the first inner cavity 101 and the second inner cavity 102, and the outer wall of the inner cylinder 22 is also provided with a circulation baffle 25 which is spirally arranged downward.

[0027] Through the above arrangement, the vacuum compressed gas is sprayed from the air inlet 11 into the inner cavity of the cylinder 1 toward the outer wall of the inner cylinder 22. At this time, the gas flows downward in a spiral along the annular baffle 25, and the water vapor in the gas is centrifugally separated by gravity. At this time, water droplets will condense on the inner wall of the cylinder 1 and flow downward, and the water on the inner wall of the cylinder 1 will accumulate at the bottom of the inner cavity of the cylinder 1.

[0028] It is worth mentioning here that the bottom wall of the inner tube 22 is located above the accumulated water surface. At this time, the gas flowing along the circulation baffle 25 flows upward through the gap between the accumulated water surface and the inner tube 22, flows into the first inner cavity 101 through the inner cavity of the inner tube 22, and is finally discharged outward from the gas outlet 12.

[0029] During this process, the gas moving along the annular baffle 25 will still come into contact with the accumulated water, resulting in a poor gas-water separation effect.

[0030] Therefore, in this embodiment, if Figure 2 , Figure 3 and Figure 4 As shown, the outer side of the inner cylinder 22 is sleeved with an outer cylinder 23, and the outer cylinder 23 is provided with a sealing bottom plate 234 that closes the bottom opening, and the peripheral wall of the outer cylinder 23 is provided with a plurality of through holes 232 for water to be discharged outward, wherein a circulation cavity 24 for compressed gas to flow through is reserved between the inner wall of the outer cylinder 23 and the outer wall of the inner cylinder 22, and the circulation baffle 25 is installed in the circulation cavity 24 and spirally coiled around the axial direction of the inner cylinder 22, specifically, the inner wall of the circulation baffle 25 is fixedly connected to the outer wall of the inner cylinder 22, and the outer wall of the circulation baffle 25 is fixedly connected to the inner wall of the outer cylinder 23, and a gap for gas to pass through is reserved between the bottom of the inner cylinder 22 and the sealing bottom plate 234.

[0031] Through the above arrangement, the gas entering from the air inlet 11 enters the second inner cavity 102 on the lower side of the partition plate 21, and then enters the annular cavity 24. At this time, the gas spirals downward along the inner cylinder 22 under the guiding action of the annular baffle 25. At this time, the water vapor in the compressed gas is thrown out to the outside of the outer cylinder 23 through the through hole 232 under the action of centrifugal force, thereby realizing the steam-water separation operation. At this time, the gas flows from the gap between the sealing bottom plate 234 and the bottom of the inner cylinder 22 to the inner cavity of the inner cylinder 22, and the gas rises into the first inner cavity 101, and then flows out from the air outlet 12. In this process, the gas after the steam-water separation will not contact the water accumulated at the bottom of the cylinder 1 again, thereby reducing the water vapor content in the exhaust gas and improving the steam-water separation effect.

[0032] In order to prevent the gas in the annular cavity 24 from passing through the through hole 232 to the outside of the outer cylinder 23, in this embodiment, Figure 2 , Figure 3 and Figure 5As shown, the peripheral wall of the outer cylinder 23 is sleeved with absorbent cotton 3, wherein the absorbent cotton 3 is wrapped around the outer side of the outer cylinder 23 to seal the through hole 232, and the outer side of the absorbent cotton 3 is also wrapped with a sealing film 4.

[0033] Through the above-mentioned arrangement, since the absorbent cotton 3 blocks the through hole 232 from the outside of the outer tube 23, when the compressed air flows inside the annular cavity 24, the separated water will be absorbed by the absorbent cotton 3 through the through hole 232. At this time, the absorbent cotton 3 has a certain effect on preventing the gas from passing out from the through hole 232; however, when the gas flows faster and there is not enough water in the absorbent cotton 3, the absorbent cotton 3 cannot form a barrier to block the flow of gas. At this time, part of the gas can still pass through the absorbent cotton 3. Here, since the outer side of the absorbent cotton 3 is wrapped with a closed film 4, the effect of the absorbent cotton 3 on blocking the gas flow is enhanced, the effect of gas-water separation is improved, and the gas is prevented from passing out of the outer tube 23.

[0034] With the use of the steam-water separator, the moisture accumulated in the absorbent cotton 3 gradually increases. When the absorbent cotton 3 is in a saturated state, if the absorbent cotton 3 is not treated, the steam-water separation effect will be reduced. Therefore, the moisture accumulated in the absorbent cotton 3 needs to be cleaned.

[0035] In this embodiment, if Figure 2 , Figure 4 and Figure 5 As shown, it includes a squeezing roller 5, wherein the squeezing roller 5 is arranged on the outside of the outer cylinder 23 and along the axial direction of the outer cylinder 23, the peripheral wall of the squeezing roller 5 abuts against the closing film 4 and squeezes the absorbent cotton 3, and also includes a driving mechanism for driving the squeezing roller 5 to rotate around the axis of the outer cylinder 23.

[0036] Through the above arrangement, during the process of steam-water separation, the steam-water separation equipment uses the driving mechanism to drive the squeezing roller 5 to rotate around the axis of the outer cylinder 23, so that the squeezing roller 5 squeezes the absorbent cotton 3, and then the water in the absorbent cotton 3 drips down from the bottom of the absorbent cotton 3, and then the absorbent cotton 3 is processed, so that the absorbent cotton 3 can continuously absorb water to prevent the absorbent cotton 3 from being saturated; the water squeezed out of the absorbent cotton 3 will drip down to the bottom of the inner cavity of the cylinder 1.

[0037] Since the absorbent cotton 3 is squeezed by the squeezing roller 5, there is a risk that the water in the absorbent cotton 3 will flow back to the circulation chamber 24 through the through hole 232. In order to avoid the water flowing back to the circulation chamber 24 from contacting with the gas as much as possible, in this embodiment, Figure 3 and Figure 6As shown, the outer wall of the circulating baffle 25 is provided with a bent edge 26, wherein the bent edge 26 and the inner wall of the outer tube 23 form a drainage groove 27, and the drainage groove 27 is spirally wound downward along with the circulating baffle 25. A drainage hole 233 is provided on the side wall at the bottom of the outer tube 23, and the tail end of the drainage groove 27 penetrates into the drainage hole 233.

[0038] Through the above arrangement, when the absorbent cotton 3 is squeezed by the squeezing roller 5, the water that flows back to the circulation chamber 24 through the through hole 232 flows downward along the inner wall of the outer tube 23 and is received by the drainage groove 27, wherein the water in the drainage groove 27 is drained to the bottom of the absorbent cotton 3 outside the outer tube 23 through the drainage hole 233, thereby reducing the risk of the water in the circulation chamber 24 being carried away by the air again.

[0039] In order to discharge the water accumulated at the bottom of the cylinder 1, in this embodiment, Figure 1 and Figure 2 As shown, a drain port 13 is installed at the bottom of the cylinder 1, wherein a valve is installed on the drain port 13. When the valve is opened, the accumulated water at the bottom of the inner cavity of the cylinder 1 is discharged outward through the drain port 13.

[0040] In order to realize the rotation of the squeezing roller 5, in this embodiment, as shown in FIG. Figure 2 and Figure 5 As shown, the driving mechanism includes a motor 7 and a rotating plate 6, wherein the output shaft of the motor 7 is fixedly connected to the rotating plate 6, the output shaft of the motor 7 coincides with the axis of the outer cylinder 23, and the squeezing roller 5 is rotatably mounted on the rotating plate 6.

[0041] In order to realize the installation of the motor 7, in this embodiment, as shown in FIG. Figure 2 and Figure 6 As shown, the blocking bottom plate 234 is recessed upward to form a storage cavity 28, including a closing plate 29 that blocks the bottom opening of the storage cavity 28, wherein the closing plate 29 is fixedly connected to the blocking bottom plate 234 by bolts, and the motor 7 is installed in the storage cavity 28.

[0042] Here, the motor 7 is located in the storage chamber 28 , which can reduce the influence of water accumulated at the bottom of the cylinder 1 on the normal operation of the motor 7 .

[0043] The outer cylinder 23 and the inner cylinder 22 are fixed to form a whole through the annular partition plate 25, wherein the partition plate 21 is fixedly installed on the top of the inner cylinder 22. In order to install the structure here into the inner cavity of the cylinder 1, in this embodiment, as shown in FIG. Figure 2 , Figure 3 and Figure 4As shown, the cylinder 1 includes an end cover 14, wherein the end cover 14 is fixedly connected to the cylinder 1 by bolts. When the end cover 14 is removed from the cylinder 1, an opening is left on the cylinder 1 for the partition plate 21, the inner cylinder 22 and the outer cylinder 23 to be installed into the inner cavity of the cylinder 1. After the installation is completed, the end cover 14 is fixed to the cylinder 1.

[0044] In order to fix the outer cylinder 23, a space for storing accumulated water is reserved between the bottom of the outer cylinder 23 and the bottom wall of the inner cavity of the cylinder body 1. In this embodiment, Figure 3 As shown, a supporting retaining ring 15 is fixedly provided on the inner wall of the cylinder 1, wherein the supporting retaining ring 15 is located below the air inlet 11 and the air outlet 12, and the top side wall of the outer cylinder 23 is provided with a retaining edge 231 extending radially outward, and when installed, the bottom wall of the retaining edge 231 abuts against the top wall of the supporting retaining ring 15.

[0045] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims are included in the present invention.
