Description

Technical Field

[0001] The present application relates to the technical field of compressors, and in particular to a skid-mounted compressor gas processing device and process. Background Art

[0002] The skid-mounted compressor is a compressor that has the compressor body and related ancillary equipment (such as motors, cooling systems, control systems, buffers, separators, heat exchangers, valves, instruments, oil pumps, water pumps, etc.) installed on a common base (usually made of steel sections such as channel steels and I-beams, etc.), forming an integrated, modular, movable, and integrally installable compressor unit.

[0003] At the beginning of the compressor gas treatment process, the air is first filtered through an air filter, which mainly filters impurities in the air to prevent solid particles and other impurities from entering the compressor, reducing the wear and damage of the compressor, and extending the service life of the compressor. At the same time, it can also improve the quality of compressed gas, reduce the burden of subsequent processing links, and ensure that the final output gas has high purity and quality. After using the filter element in a conventional air filter for a period of time, the air filter shell needs to be opened and the filter element cleaned to ensure the filtering effect of the filter element during subsequent use.

[0004] In actual use, the outer shell needs to be opened every time the filter element is cleaned, which has the defect of inconvenient cleaning and maintenance of the filter element. Summary of the invention

[0005] In order to facilitate timely cleaning and maintenance of the filter element and improve the convenience of cleaning and maintenance of the filter element, the present application provides a skid-mounted compressor gas processing device and process.

[0006] In a first aspect, the present application provides a skid-mounted compressor gas processing device, which adopts the following technical solution:

[0007] A skid-mounted compressor gas processing device comprises a housing and a filter element arranged in the housing, wherein there is a distance between an outer wall of the filter element and an inner wall of the housing, and further comprises:

[0008] A cleaning ring is slidably arranged inside the housing, the cleaning ring reciprocates along the length direction of the filter element, the cleaning ring is sleeved outside the filter element, and there is a distance between the inner wall of the cleaning ring and the outer wall of the filter element, and there is a distance between the outer wall of the cleaning ring and the inner wall of the housing;

[0009] A cleaning brush is slidably arranged on the cleaning ring and reciprocates in a direction approaching or moving away from the filter element;

[0010] An air extraction pipe penetrates the housing and is slidably arranged relative to the housing. A first air inlet is provided on the cleaning ring. One end of the air extraction pipe is located outside the housing, and the other end penetrates into the housing and is fixed to the cleaning ring for communication with the first air inlet. The inlet end of the first air inlet is arranged toward the filter element.

[0011] A drive assembly is used to provide power for sliding of the cleaning ring.

[0012] By adopting the above technical solution, when cleaning and maintaining the filter element, the driving component is started, and the cleaning ring is slid along the length direction of the filter element. The cleaning ring drives the first air inlet to sweep along the length direction of the filter element, and air suction is performed on the impurities on the filter element, thereby reducing direct contact with the filter element and reducing damage to and disturbance of the fibers and nano-coating on the surface of the filter element. If a filter element type that can be cleaned is encountered, the cleaning brush is slid while air suction is applied so that the bristles of the cleaning brush abut against the surface of the filter element. As the cleaning ring moves, the cleaning brush cleans the surface of the filter element. The combination of the two methods can cope with the cleaning of different types of filter elements. At the same time, there is no need to repeatedly open the outer shell, thereby achieving the effect of facilitating timely cleaning and maintenance of the filter element.

[0013] Optionally, a groove is provided on the cleaning ring, and the groove is provided along the circumferential direction of the outer wall of the cleaning ring. An air supply pipe and an airbag are provided on the cleaning ring. The airbag is annularly sleeved in the groove. One end of the air supply pipe is located outside the outer shell, and the other end is fixed to the cleaning ring for supplying air into the airbag; when the airbag is inflated, the edge of the airbag abuts against the inner wall of the outer shell.

[0014] By adopting the above technical solution, air is inflated into the airbag through the air supply pipe to expand the airbag. In the expanded state, the edge of the airbag can abut against the inner wall of the outer shell, so that the airbag can clean the inner wall of the outer shell as the cleaning ring moves. When there is no need to clean the inner wall of the outer shell, the gas in the airbag is extracted through the air supply pipe, so that the airbag retracts into the groove in a deflated state without affecting the movement of the cleaning ring.

[0015] Optionally, a hidden groove is provided on the cleaning ring, and a first spring is arranged on the cleaning ring, one end of the cleaning brush is located in the hidden groove, one end of the first spring is fixed to the end of the cleaning brush located in the hidden groove, and the other end is fixedly connected to the groove wall of the hidden groove, and the first spring is used to push the cleaning brush to move away from the filter element; the cleaning ring is provided with an adjustment component for pushing the cleaning brush to move toward the filter element.

[0016] By adopting the above technical solution, when not subject to external force, the first spring pushes the cleaning brush to move away from the filter element, thereby ensuring that the cleaning brush does not wear the outer wall of the filter element. By adjusting the coordination of the components, when the filter element type can withstand physical cleaning, the cleaning brush is pushed to abut against the outer wall of the filter element to clean the outer wall of the filter element.

[0017] Optionally, the adjustment assembly includes an adjustment ring and a boss, the adjustment ring is rotatably set on the cleaning ring, the center lines of the adjustment ring and the cleaning ring are colinear, the adjustment ring rotates relative to the adjustment ring, the adjustment ring and the cleaning brush are located on the same side wall of the adjustment ring, the boss is fixed on the inner wall of the adjustment ring, and the boss is located on the side of the cleaning brush away from the filter element; the boss follows the movement of the adjustment ring to push the cleaning brush to move closer to the filter element.

[0018] By adopting the above technical solution, when the filter element type can withstand physical cleaning, the adjusting ring is rotated and the boss moves with the adjusting ring. During the movement, the boss gradually approaches the cleaning brush and then abuts against the cleaning brush, and then pushes the cleaning brush to abut against the outer wall of the filter element, so that the cleaning brush cleans the outer wall of the filter element.

[0019] Optionally, a locking assembly is provided on the cleaning ring, the locking assembly includes a locking box, a latch and a second spring, the locking box and the adjusting ring are located on the same side wall of the cleaning ring, the locking box is located on the side of the adjusting ring away from the filter element, the locking box is fixed on the cleaning ring, the latch is slidably arranged on the locking box and slides in a direction close to or away from the adjusting ring, and the second spring is used to push the latch to slide in a direction close to the adjusting ring; a slot for inserting the end of the latch is provided on the adjusting ring.

[0020] By adopting the above technical solution, the locking assembly can limit the position of the adjusting ring, so that the adjusting ring can remain fixed relative to the cleaning ring when it does not need to rotate. This is achieved by the second spring pushing the end of the latch pin to be inserted into the corresponding slot.

[0021] Optionally, the shell includes a connecting ring, which is located at one end of the shell and rotates relative to the shell, the center line of the connecting ring is collinear with the center line of the adjustment ring, and an insertion rod is fixed on the connecting ring, the insertion rod passes through the connecting ring, and the insertion rod is located at one end inside the shell for being inserted into a slot and pushing the pin out of the slot.

[0022] By adopting the above technical solution, when the cleaning ring moves along the length direction of the filter element with the adjusting ring until it moves close to one end of the outer shell, the insertion rod is inserted into the slot in the horizontal direction. As the insertion rod goes deeper, the insertion rod eventually pushes the pin out of the slot. At this time, the connecting ring is rotated, and the insertion rod and the slot can limit each other in the rotation direction. The adjusting ring can be rotated by the insertion rod to change the position of the cleaning brush.

[0023] Optionally, the cleaning brush is arc-shaped at one end close to the filter element and the arc-shaped concave surface is arranged toward the filter element, four cleaning brushes are provided, adjacent cleaning brushes are distributed at intervals along the circumference of the cleaning ring, and the four cleaning brushes form a full circle when they are abutted end to end; the bosses are set corresponding to the number of cleaning brushes, and adjacent bosses are distributed at intervals along the circumference of the adjustment ring.

[0024] By adopting the above technical solution and setting the number and shape of the cleaning brushes, all the cleaning brushes can fully cover the surface of the filter element when working, and fully clean the surface of the filter element.

[0025] Optionally, a second air inlet is provided on the cleaning ring, and an inlet end of the second air inlet is arranged toward the inner wall of the shell, and the end of the exhaust pipe fixed to the cleaning ring is simultaneously connected to the second air inlet.

[0026] By adopting the above technical solution, after the airbag cleans the inner wall of the shell, the debris and dust dropped after cleaning are sucked into the second air inlet and then discharged through the exhaust pipe, thereby reducing the phenomenon of debris falling on the filter element.

[0027] Optionally, a driving wheel and a pressure plate are provided on the outer wall of the shell, and the outer walls of the air supply pipe and the air exhaust pipe are provided with pressure grooves spaced apart along their own length directions. The driving wheel is gear-shaped, and the teeth of the driving wheel itself are engaged with the pressure grooves. The driving wheel is arranged to rotate relative to the shell, and the pressure plate is used to press the air supply pipe and the air exhaust pipe to keep them in an engaged state with the driving wheel.

[0028] By adopting the above technical solution, the air supply pipe and the air exhaust pipe move with the movement of the cleaning ring. When the movement state of the cleaning ring is the return state, the air supply pipe and the air exhaust pipe parts located inside the shell need to be poured out of the shell. At this time, the pressure plate ensures that the air supply pipe and the air exhaust pipe can engage with the driving wheel. The rotation of the driving wheel ensures that the air supply pipe and the air exhaust pipe are poured out of the shell in an orderly manner, avoiding the phenomenon of the air supply pipe and the air exhaust pipe being blocked in the shell.
