Description

Technical Field

[0001] This utility model relates to the field of air compressor technology, specifically to an air drying device for an air compressor. Background Technology

[0002] An air compressor is a device used to compress gas. Similar in construction to a water pump, most air compressors are reciprocating piston, rotary vane, or rotary screw types. Generally, air compressors dry the air before compressing it. The desiccant used for air drying needs to be replaced periodically. However, traditional air compressors require the compressor to be stopped before replacement, which disrupts operation. Furthermore, replacing the desiccant often requires auxiliary tools, making it quite cumbersome. Therefore, we propose an air drying device for air compressors to solve these problems.

[0013] Compared with the prior art, the present invention provides an air drying device for an air compressor, which has the following beneficial effects:

[0014] 1. An air drying device for an air compressor, by setting an air intake pipe, an installation pipe and an air drying filter, can start the air compressor body, and outside air can enter the air intake pipe through the dustproof air intake screen installed on the air intake pipe, and can enter the interior of the installation pipe through the filter screen on the installation pipe. Since an air drying filter is installed in the installation pipe, the air entering the pipe can be dried by the air drying filter.

At this time, pressing down on the movable plate and rotating it moves the locking block out of the slot, allowing the installation pipe to be removed from the intake pipe. Then, rotating the rotating plate allows the installation rod to be rotated out of the installation plate, at which point the air drying filter element can be removed from the installation rod. A new air drying filter element is inserted into the installation rod, and the installation rod is rotated into the installation plate, thus completing the replacement of the air drying filter element. Afterwards, the installation pipe can be inserted into the intake pipe, allowing the sealing sleeve to be inserted into the groove at the top of the intake pipe. Under the compression of the spring, the sealing plate can be tightly attached to the sealing sleeve. Rotating the movable plate then rotates the locking block into the slot in the intake pipe. This not only eliminates the need to stop the air compressor when replacing the air drying filter element but also facilitates the replacement of the air drying filter element.

Air intake pipes 5 are fixedly installed on the top and both sides of the air intake manifold 8, and valves 7 are installed at the lower part of each of the three air intake pipes 5, allowing control of the air intake through the valves 7. An installation pipe 601 is provided inside the air intake pipe 5. Multiple locking blocks 603 are evenly welded to the upper outer ring of the installation pipe 601. A movable plate 6 is welded to the top of the installation pipe 601, and an installation plate 605 is welded to the upper part of the inner wall of the installation pipe 601. An installation bottom cover 11 is provided at the lower part of the interior of the installation pipe 601. An air drying filter element 9 is placed between the installation bottom cover 11 and the installation plate 605, which can dry the air entering the air compressor body 1.

[0024] In this embodiment, a through hole is provided at the lower part of the outer ring of the air intake pipe 5, and a dustproof air intake mesh 501 is fixedly installed in the through hole to prevent dust. A through hole is provided at the lower part of the outer ring of the mounting pipe 601, and a filter screen 602 is installed in the through hole to filter the air. Multiple slots 502 are provided on the upper part of the inner wall of the air intake pipe 5, and the slots 502 are L-shaped. The multiple slots 502 provided on the upper part of the inner wall of the air intake pipe 5 correspond one-to-one with the multiple locking blocks 603 uniformly welded to the upper outer ring of the mounting pipe 601. The multiple slots 502 uniformly provided on the upper part of the inner wall of the air intake pipe 5 correspond to the mounting pipe 601. Multiple locking blocks 603 are evenly welded to the upper outer ring and match each other, so that the locking blocks 603 can be inserted into the locking slot 502. A sealing sleeve 604 is welded to the bottom surface of the movable plate 6 and outside the mounting tube 601. A groove is opened on the top outer wall of the air intake pipe 5 for the sealing sleeve 604 to be inserted. Multiple sets of springs 1201 are evenly installed on the bottom inner wall of the groove opened on the top outer wall of the air intake pipe 5. A sealing plate 12 is installed on the top of the multiple sets of springs 1201. The sealing plate 12 can squeeze the bottom of the sealing sleeve 604 under the action of the springs 1201. The sealing plate 12 can be made of rubber.

[0025] Both the mounting base 11 and the mounting plate 605 have annular grooves on their adjacent sides, and sealing rings 10 are placed in both annular grooves. The top and bottom of the air-drying filter element 9 are provided with annular protrusions, which are respectively installed in the annular grooves on the adjacent sides of the mounting plate 605 and the mounting base 11, facilitating the fixation of the air-drying filter element 9. The air-drying filter element 9 is concentrically shaped and can be inserted into the mounting rod 1101. The air-drying filter element 9 contains substances that dry the air, such as silica gel, calcium oxide (CaO), and solid sodium hydroxide. The mounting rod 1101 is welded to the center of the mounting base 11, and the upper part of the mounting rod 1101 is threaded. The center of the bottom of the mounting plate 605 has a thread that matches the upper thread of the mounting rod 1101. The threaded groove on the mounting rod 1101 can rotate into the threaded groove on the mounting plate 605. The mounting bottom cover 11 is provided with an air inlet mesh 1103 located on the inner ring of the air drying filter element 9, which can facilitate the entry of outside air. Multiple rotating plates 1102 are evenly welded on the bottom surface of the mounting bottom cover 11.

Two traveling wheels 2 are installed on the bottom right side of the air compressor body 1, which can facilitate the movement of the air compressor body 1. A support frame 3 is installed on the bottom left side of the air compressor body 1, which can support the left side of the air compressor body 1. A handle 4 is installed on the top left side of the air compressor body 1. The support frame 3 can be lifted by lifting the handle 4, and the air compressor body 1 can be moved to the corresponding location by the traveling wheels 2.

[0026] The working principle and usage process of this utility model: This air compressor air drying device can lift the support frame 3 by lifting the handle 4 upwards, and can move the air compressor body 1 to the corresponding location by the walking wheels 2. The air compressor body 1 can be started, and outside air can enter the intake pipe 5 through the dustproof intake screen 501 installed on the intake pipe 5, and can enter the interior of the mounting pipe 601 through the filter screen 602 on the mounting pipe 601. Since the mounting pipe 601 is equipped with an air drying filter element 9, the incoming air can be dried by the air drying filter element 9, and the dried air can be compressed by the air compressor body 1. If the air drying filter element 9 needs to be replaced, the valve 7 on the corresponding intake pipe 5 can be closed. At this time, the movable plate 6 can be pressed down and rotated to remove the locking block 603 from the locking slot 502. The movable plate 6 can be lifted upwards to remove the air compressor body 1. The mounting tube 601 is removed from the intake pipe 5. Then, the rotating plate 1102 can be rotated to remove the mounting rod 1101 from the mounting plate 605. At this time, the air drying filter 9 can be removed from the mounting rod 1101 and replaced with a new air drying filter 9. The new air drying filter 9 is inserted into the mounting rod 1101, and the mounting rod 1101 is rotated into the mounting plate 605, thus completing the replacement of the air drying filter 9. Then, the mounting tube 601 can be inserted into the intake pipe 5. At this time, the sealing sleeve 604 can be inserted into the groove opened at the top of the intake pipe 5, and under the compression of the spring 1201, the sealing plate 12 can be tightly attached to the sealing sleeve 604. Then, the movable plate 6 can be rotated to rotate the locking block 603 into the locking groove 502 opened in the intake pipe 5. This not only achieves the goal of replacing the air drying filter 9 without stopping the air compressor body 1, but also facilitates the replacement of the air drying filter 9.
