Description

Technical Field

[0001] The utility model relates to the technical field of vortex gas compressors, in particular to an air filtering mechanism of a vortex gas compressor based on the automatic drainage principle. Background Art

[0002] The scroll gas compressor is a compressor that uses the rotation of the body to cause the volume change of the volume chamber to compress the gas. It is mainly composed of a fixed involute scroll and an involute moving scroll that eccentrically rotates and translates. The two scrolls are interlocked, and the gas is gradually compressed in several crescent-shaped compression chambers formed by the interlocking of the moving and static disks through the eccentric movement of the moving scroll. During the compression process, the gas is sucked into the periphery of the static disk through the air filter element. As the eccentric shaft rotates, the gas is gradually compressed and finally discharged continuously from the axial hole of the central component of the static disk.

[0003] During the gas compression process, as the air is compressed and cooled, the moisture in the air tends to condense into liquid water. If this condensed water is not discharged in time, it will accumulate inside the compressor or in the pipeline, causing the condensed water to occupy the volume of the compressor and reduce the compression efficiency; secondly, the long-term accumulation of condensed water may cause corrosion and bacterial growth, causing pollution to the compressor and the output air; finally, the condensed water may also block the airflow channel and affect the normal operation of the compressor. Utility Model Content

[0004] In view of the above problems, the purpose of the utility model is to overcome the deficiencies of the prior art and design an air filter mechanism for a vortex gas compressor based on the principle of automatic drainage.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an air filtering mechanism of a vortex gas compressor based on the principle of automatic drainage, comprising a shell, a vortex generator, an intake pipe, an exhaust pipe and a filter assembly, a separation chamber is provided in the shell, the vortex generator is arranged in the separation chamber, one end of the intake pipe and the exhaust pipe are connected to the vortex generator, the filter assembly is arranged at the other end of the intake pipe, and a drainage port is provided at the bottom of the separation chamber.

[0007] As a preferred embodiment of the utility model, a spiral guide groove is provided in the vortex generator, one end of the guide groove is connected to the second opening, and the other end of the guide groove is located at the third opening.

[0008] As a preferred embodiment of the present invention, the filter assembly comprises a filter sleeve, and the filter sleeve is detachably mounted on an end of the air intake pipe away from the vortex generator.

[0010] As a preferred embodiment of the utility model, an outer side of one end of the air inlet pipe away from the vortex generator is provided with an external thread, and an inner thread matching with the external thread is provided in the filter sleeve.

[0011] As a preferred embodiment of the utility model, an inverted cone-shaped guide surface is provided at the bottom of the separation chamber, a through hole is provided at the bottom end of the guide surface, and the through hole is connected to the drain outlet.

[0026] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0027] like Figures 1 to 7 As shown, the utility model describes an air filtering mechanism for a vortex gas compressor based on the principle of automatic drainage, comprising a shell 1, a vortex generator 2, an air intake pipe 3, an exhaust pipe 4 and a filter assembly 5, wherein a separation chamber 11 is provided in the shell 1, the vortex generator 2 is arranged in the separation chamber 11, one end of the air intake pipe 3 and the exhaust pipe 4 are connected to the vortex generator 2, the filter assembly 5 is arranged at the other end of the air intake pipe 3, and a drainage port 12 is provided at the bottom of the separation chamber 11.

[0028] The utility model intercepts large particles of impurities and dust in the air through the filter assembly 5, thereby ensuring that the air entering the vortex gas compressor reaches a certain cleanliness standard, improving the service life and performance of the vortex gas compressor, and avoiding malfunctions and damage caused by impurities entering the interior of the vortex gas compressor. When the air filtered by the filter assembly 5 enters the vortex generator 2, the vortex generator 2 causes the air to form a high-speed rotating vortex. This rotational motion not only helps to further remove impurities in the air, but also can separate the moisture in the air. Due to the effect of centrifugal force, the moisture is thrown to the wall of the separation chamber 11, while the dry air continues to remain in the center of the vortex. The separated moisture and impurities accumulate at the bottom of the separation chamber 11 under the action of gravity, and are finally discharged through the drain 12. Thereby reducing the moisture in the air entering the vortex gas compressor, and then reducing the generation of condensed water when the air is compressed.

[0029] Further, refer to Figure 2 , Figure 3 and Figure 4 As shown, a first opening 21 is provided at the top of the vortex generator 2, and the first opening 21 is connected to the exhaust pipe 4. A second opening 22 is provided at the side of the vortex generator 2, and the second opening 22 is connected to the intake pipe 3. A third opening 23 is provided at the bottom of the vortex generator 2.

[0030] The first opening 21 is connected to the exhaust pipe 4, ensuring that the dry air processed by the vortex generator 2 can be discharged smoothly for subsequent use or entering other process links. The first opening 21 is located at the top, which is conducive to the smooth flow of dry air and avoids poor airflow caused by structural obstruction.

[0031] The second opening 22 is connected to the air intake pipe 3, and the air preliminarily filtered by the filter assembly 5 can enter the vortex generator 2 through the air intake pipe 3. The side position allows the air intake pipe 3 to be conveniently connected to the vortex generator 2, while also providing sufficient space for the air to enter, ensuring smooth air flow.

[0032] Inside the vortex generator 2, due to the centrifugal force, the water is thrown toward the wall and accumulates at the bottom. The water enters the separation chamber 11 connected to the drain port 12 through the third opening 23, so that the accumulated water can be discharged smoothly, thereby reducing the water content in the air entering the vortex gas compressor, and further reducing the generation of condensed water when the air is compressed.

[0033] Further, refer to Figure 5 As shown, a spiral guide groove 24 is provided in the vortex generator 2 , one end of the guide groove 24 is connected to the second opening 22 , and the other end of the guide groove 24 is located at the third opening 23 .

[0034] First, one end of the guide groove 24 is connected to the second opening 22, and the air preliminarily filtered by the filter assembly 5 can smoothly enter the guide groove 24. The spiral structure of the guide groove 24 enables the air to flow along a specific path when entering the vortex generator 2, forming a stronger vortex effect. This vortex effect not only helps to further remove impurities in the air, but also can more effectively separate moisture from the air.

[0035] Secondly, the other end of the guide groove 24 is located at the third opening 23. When the air forms a vortex in the vortex generator 2, due to the centrifugal force, the water flows along the guide groove 24 and finally enters the separation chamber 11 through the third opening 23. It leaves the separation chamber 11 through the drain port 12, thereby ensuring the effective discharge of the water.

[0036] Further, refer to Figure 1 and Figure 7 As shown, the filter assembly 5 includes a filter sleeve 51 , and the filter sleeve 51 is detachably mounted on an end of the intake pipe 3 away from the vortex generator 2 .

[0037] Specifically, the filter sleeve 51 is detachably mounted on the end of the air intake pipe 3 away from the vortex generator 2. This allows the filter sleeve 51 to be easily connected to and separated from the air intake pipe 3. After the filter sleeve 51 has been used for a period of time, its filtering effect will gradually decrease due to the accumulation of impurities and dust in the air. At this time, the user can easily remove the filter sleeve 51 from the air intake pipe 3, clean or replace it, and thus restore its filtering performance.

[0038] At the same time, the detachable design also facilitates users to select appropriate filter sleeves 51 according to different working environments and needs. For example, in some environments, there may be more impurities and dust in the air, and in this case, a filter sleeve 51 with better filtering effect can be selected; while in other environments, only basic filtering functions may be required, so a relatively simple filter sleeve 51 can be selected. This flexibility enables the air filtering mechanism of the utility model to adapt to different application scenarios.

[0039] Further, refer to Figure 7 As shown, a filter cavity 52 is provided in the filter sleeve 51 , and a plurality of filter holes 53 arranged at equal intervals are provided on the wall of the filter sleeve 51 .

[0040] Specifically, a filter chamber 52 is provided in the filter sleeve 51. The shape and size of the filter chamber 52 can be optimized by the user according to different working environments and requirements to ensure that the air can fully contact the filter material when passing through, thereby achieving an efficient filtering effect. A plurality of filter holes 53 arranged at equal intervals are provided on the cylinder wall of the filter sleeve 51. The filter holes 53 allow the air that has undergone preliminary filtration to enter the vortex generator 2 while preventing large particles of impurities from passing through. The diameter and distribution density of the filter holes 53 can be optimized according to different working environments and requirements to ensure that impurities are effectively intercepted while maintaining sufficient ventilation. The equidistant arrangement not only ensures the uniformity of filtration, but also helps to improve the structural stability of the filter sleeve 51.

[0041] Furthermore, an outer side of the end of the air intake pipe 3 away from the vortex generator 2 is provided with an external thread, and an internal thread matching the external thread is provided in the filter sleeve 51. By rotating the air intake pipe 3 and the filter sleeve 51, the external thread and the internal thread can be tightly engaged together to form a connection that is not easy to loosen. This connection method not only ensures the smoothness of air passing through the air intake pipe 3 and the filter sleeve 51, but also avoids the problem of air leakage caused by loose connection.

[0042] Further, refer to Figure 6 As shown, the bottom of the separation chamber 11 is provided with an inverted cone-shaped guide surface 13, and the bottom end of the guide surface 13 is provided with a through hole, which is connected to the drain port 12. The inverted cone-shaped guide surface 13 has a natural guiding effect, which can make the condensed water accumulated in the separation chamber 11 flow smoothly along the guide surface 13 under the action of gravity. Since the guide surface 13 is inverted cone shape, the condensed water can flow to the through hole at the bottom thereof more quickly, thereby avoiding the retention of water at the bottom of the separation chamber 11.

[0043] Further, refer to Figure 1 As shown, a one-way valve 6 is provided at the drain port 12. The main function of the one-way valve 6 is to allow the fluid to pass through in a single direction while preventing it from flowing in the opposite direction. In the air filtration mechanism of the vortex gas compressor based on the principle of automatic drainage, the one-way valve 6 is installed at the drain port 12. The main purpose is to ensure that the condensed water can be discharged smoothly while preventing external gas or impurities from entering the compressor through the drain port 12. When moisture in the air accumulates in the vortex generator 2 and flows to the drain port 12, the one-way valve 6 automatically opens under the pressure of the water to allow the moisture to be discharged. When there is no moisture to be discharged, the one-way valve 6 remains closed, effectively isolating the internal and external environments of the compressor.
