Description

Technical Field

[0001] The utility model relates to the technical field of air compressors, in particular to an air intake drying device for an air compressor. Background Art

[0002] An air compressor, namely an air-type compressor, is a device that pressurizes air through a compressor and then enters the tank body, so that the air pressure is greater than the atmospheric pressure. Usually, when air enters the tank body, it needs to be dried to remove moisture in the air. In the existing drying cylinder, desiccants are filled inside, and the two ends of the drying cylinder limit the desiccants by interference fit, so that the air can be dried by the dryer and then enter the tank body. However, the use of interference fit makes it impossible to replace the desiccants after they fail, and the entire drying cylinder needs to be replaced, resulting in complex replacement and high cost. In addition, in the existing drying cylinder, after the desiccants are encapsulated, the cover body is clamped with the cylinder body by interference fit. Long-term use and vibration will cause the gap between the desiccants to become larger, resulting in the desiccants rubbing out powder. The powder is easily carried into the valve port or the air tank body by the air, resulting in problems such as valve port blockage or powder entering the tank body, which affects the purity of the compressed air. Content of the Utility Model

[0043] An air compressor intake drying device provided according to the present utility model includes a first cylinder group and a second cylinder group.

[0044] Hereinafter, the specific structures of the above components of the air compressor intake drying device according to the present embodiment will be described.

[0045] In the present embodiment, as Figures 1 to 5 shown, the first cylinder group includes a first cylinder body 10 and a first cover body 11. An accommodation cavity 100 is formed inside the first cylinder body 10. The first cylinder body 10 may be a cylindrical or prismatic tubular structure. The first cover body 11 is detachably connected to the first cylinder body 10 to close one end of the accommodation cavity 100 when the first cover body 11 and the first cylinder body 10 are connected, and to disassemble the first cover body 11 and the first cylinder body 10 to separate them when the desiccant needs to be replaced. The connection manner between the first cover body 11 and the first cylinder body 10 may be by connecting with fasteners such as screws or bolts, or by threaded connection, or by snap connection or other connection manners.

[0046] Preferably, the first cylinder group is made of a metal material, such as steel, and thus has a relatively high mechanical structure strength.

[0047] As Figures 1 to 3As shown, the second cylinder group is disposed within the accommodation cavity 100; specifically, the second cylinder group includes a second cylinder body 20 and a lifting member 30. A drying cavity 200 is formed within the second cylinder body 20 for containing a desiccant, which can be a molecular sieve. The structure of the second cylinder body 20 can be the same as that of the first cylinder body 10. The lifting member 30 is connected to the second cylinder body 20 and is capable of sliding relative to the accommodation cavity 100 so that when the desiccant needs to be replaced, the second cylinder body 20 can be extracted from the accommodation cavity 100 via the lifting member 30, facilitating the replacement of the desiccant and reducing costs.

[0048] Preferably, the second cylinder body 20 is made of a plastic material, such as PC material, which is simple to manufacture and helps reduce costs.

[0049] In this embodiment, as Figures 1 to 5 shown, the end of the lifting member 30 away from the second cylinder body 20 extends towards the first cover 11, such that the lifting member 30 is formed as a rod-shaped structure disposed between the second cylinder body 20 and the first cover 11, thereby facilitating the replacement personnel to easily pull out the second cylinder body 20 via the lifting member 30 at the end side of the accommodation cavity 100.

[0050] In a preferred embodiment, as Figure 2 shown, the end of the lifting member 30 away from the second cylinder body 20 is formed as a lifting portion 31 having an annular structure, further facilitating the fingers of the replacement personnel to extend in for applying force to take out the second cylinder body 20; in this embodiment, the lifting portion 31 can be an annular structure such as a circle, a triangle or a polygon, and the lifting portion 31 can be an annular structure with an opening 211 or a closed annular structure.

[0051] Furthermore, as Figure 2 and Figure 5 shown, the two ends of the accommodation cavity 100 are provided with a first air port 111, a second air port 121 and a secondary port 122. The first air port 111, the second air port 121 and the secondary port 122 are all through-hole structures communicating with the accommodation cavity 100. One of the first air port 111 and the second air port 121 is for intake air and the other is for exhaust air. The secondary port 122 can be used for draining water and / or installing accessories such as a pressure valve. In this embodiment, the first air port 111 is opened on the first cover 11; the first air port 111 can be opened on the side wall of the first cover 11. However, the opening position of the first air port 111 is not limited thereto, as long as it can ensure the communication between the first air port 111 and the accommodation cavity 100.

[0052] In addition, as Figure 1 and Figure 2As shown, the first cylinder group further includes a second cover body 12 connected to the first cylinder body 10. The first cover body 11 and the second cover body 12 are arranged on both sides of the first cylinder body 10 in the axial direction. The first cover body 11 is arranged on the top of the first cylinder body 10, and the second cover body 12 is arranged on the bottom of the first cylinder body 10. The second cover body 12 and the first cylinder body 10 can be detachably connected by screw and bolt fasteners, threaded connection or snap connection. The second air port 121 and the auxiliary port 122 are opened on the second cover body 12. The second air port 121 can be opened on the side wall of the second cover body 12, and the auxiliary port 122 can be opened on the bottom wall of the second cover body 12. However, the opening positions of the second air port 121 and the auxiliary port 122 are not limited to this, as long as it can be ensured that the second air port 121 and the auxiliary port 122 can communicate with the accommodation cavity 100.

[0053] In a preferred embodiment, as Figure 2 and Figure 3 shown, the circumferential side wall of the second cylinder body 20 partially abuts against the cavity wall of the accommodation cavity 100, so as to ensure that the gas entering the accommodation cavity 100 can completely enter the drying cavity 200, avoiding the gas directly passing through the accommodation cavity 100 and discharging without entering the drying cavity 200, thereby realizing effective drying of the gas. In addition, a gap is also formed between the circumferential side wall of the remaining part of the second cylinder body 20 and the cavity wall of the accommodation cavity 100, so as to facilitate the removal of the second cylinder body 20.

[0054] Specifically, in this embodiment, as Figures 2 to 5 shown, the second cylinder body 20 includes a pipe body 21 and a cover body assembly 22. The pipe body 21 can be a cylindrical or prismatic tubular structure. The drying cavity 200 is surrounded by the inner wall of the pipe body 21, that is, the desiccant is arranged inside the pipe body 21, and an opening 211 is provided at the end of the pipe body 21; the cover body assembly 22 is arranged at the opening 211 to close the opening 211 of the pipe body 21 and prevent the desiccant from leaking out. The lifting member 30 is connected to the cover body assembly 22, and the lifting member 30 and the cover body assembly 22 can be assembled by welding, bonding, threaded connection or snap connection, etc.

[0055] More specifically, in this implementation, as Figures 2 to 5As shown in the figure, the cover assembly 22 includes a support member 221 and a throttling member 222. The support member 221 is connected to the tube body 21 and can be snap-fitted on the inner wall of the tube body 21. The throttling member 222 is disposed on the side of the support member 221 facing the drying chamber 200. The throttling member 222 is a plate-like structure, and a ventilation opening 2221 is formed in the throttling member 222 to ensure gas flow. The ventilation opening 2221 is a through-hole structure, and preferably a plurality of ventilation openings 2221 are provided and distributed on the plate surface of the throttling member 222. The support member 221 can press the throttling member 222 against the desiccant in the tube body 21 to play a limiting role on the throttling member 222, ensuring that the tube body 21 is filled with desiccant to meet the drying requirements of the gas. The throttling member 222 preferably has a certain stiffness so that it can press the desiccant to avoid the situation that the desiccant is rubbed against each other due to too large gaps between the desiccants, resulting in powder falling and blocking the valve port or entering the compressed gas container. The throttling member 222 is preferably made of stainless steel material.

[0056] In this embodiment, the lifting member 30 is connected to the throttling member 222 for easy installation.

[0057] In addition, in this embodiment, as Figures 2 to 5 shown, the cover assembly 22 further includes a filter member 223. The filter member 223 can be filter cotton. The filter member 223 is disposed on the side of the support member 221 facing the drying chamber 200, preferably on the side of the throttling member 222 facing away from the support member 221, so as to avoid the desiccant or impurities from blocking the ventilation opening 2221 and also ensure filtration while drying the gas.

[0058] In this embodiment, as Figure 4 and Figure 5 shown, openings 211 are provided at both ends of the tube body 21 in the axial direction, and two sets of cover plate assemblies are correspondingly provided. The lifting member 30 is connected to one of the cover plate assemblies.

[0059] In a preferred embodiment, as Figures 2 to 5 shown, the air compressor intake drying device further includes an elastic member 40. The elastic member 40 can be a spring. The two ends of the elastic member 40 in the telescopic direction respectively abut against the throttling member 222 and the first cover 11, so as to increase the pressing force applied by the throttling member 222 to the desiccant, ensure that the filled desiccants are pressed tightly against each other without movable gaps, and avoid the desiccants from loosening and rubbing against each other to generate more powder, thereby avoiding the situation that the powder falls into the valve port and causes blockage or the powder enters the compressed gas container and reduces the gas cleanliness. In this embodiment, after the second cylinder body 20 is assembled, the elastic member 40 is installed in the accommodating cavity 100 and then the first cover 11 is installed, so that the elastic member 40 is in a compressed state in the accommodating cavity 100 to apply a pressing force to the throttling member 222 acting on the desiccant.

[0060] In addition, under the action of the elastic member 40, one end of the second cylinder group away from the elastic member 40 can tightly abut against the second cover body 12 as described above, so that the gas flowing through the second air port 121 can all lead to the drying chamber 200, preventing the un-dried gas from entering the container filled with compressed gas. In a preferred embodiment, the first air port 111 as described above is for discharging gas, and the second air port 121 is for admitting gas.

[0061] Further, in this embodiment, as Figure 2 shown, the elastic member 40 is sleeved on the circumferential side wall of the lifting member 30 to play a guiding role in the expansion and contraction of the elastic member 40. The support member 221 is formed as an annular structure surrounding a part of the side wall of the elastic member 40, so as to ensure gas flow and can limit the elastic member 40, ensuring reliable pressing connection between the elastic member 40 and the throttling member 222.

[0062] It should be noted that when the desiccant needs to be replaced, after removing the first cover body 11 and taking out the elastic member 40, the lifting member 30 is lifted directly to take out the second cylinder body 20, and a new second cylinder body 20 can be replaced.

[0063] In addition, in this embodiment, as Figure 3 shown, the second cylinder body 20 further includes a sealing member 50. The sealing member 50 can be an elastic sealing ring. The sealing ring is annular and is clamped between the cover body assembly 22 and the tube body 21 to ensure the sealed connection between the cover body assembly 22 and the tube body 21 and prevent air leakage.

[0064] Preferably, as Figure 3 shown, a ring groove is formed on the outer wall of the support member 221, and the sealing member 50 is installed in the ring groove to play a role in limiting the sealing member 50, so that the sealing member 50 is firmly clamped between the support member 221 and the tube body 21.

[0065] The air compressor intake drying device according to the present invention includes a first cylinder body and a second cylinder body. The second cylinder body is formed with a drying chamber for containing a desiccant. The second cylinder body is disposed in the accommodating cavity of the first cylinder body, so as to realize the detachable connection between the first cylinder body and the second cylinder body. The lifting member is connected to the second cylinder body and can slide relative to the accommodating cavity, so as to extract the second cylinder body from the accommodating cavity via the lifting member when the desiccant needs to be replaced, facilitating the replacement of the desiccant and reducing costs. In addition, the setting of the elastic member can make the throttling member press the desiccant tightly, preventing dust from being generated due to friction between the desiccants.

[0066] Finally, it should be noted that the above-described embodiments are only specific embodiments of the present application, which are used to illustrate the technical solutions of the present application, rather than limiting it. The protection scope of the present application is not limited thereto. Although the present application has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that any person skilled in the art within the technical scope disclosed in the present application can still modify the technical solutions described in the foregoing embodiments or can easily think of changes, or perform equivalent replacements on some of the technical features; and these modifications, changes or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present application, and should all be covered within the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
