Description

Technical Field

[0001] This utility model relates to the field of centrifugal air compressors, and more particularly to a low-loss centrifugal air compressor. Background Technology

[0002] Centrifugal air compressors rely on high-speed rotating impellers to do work on gas. With their advantages of large flow rate and continuous air supply, they are widely used in mining, municipal engineering, and field pipeline construction. Trailer-mounted centrifugal air compressors have mobile transportation capabilities and can be quickly moved with the construction site, making them the core equipment for mobile air supply operations.

[0003] In daily operations, it has been observed that when equipment operates for extended periods in dusty or sandy environments, high concentrations of dust and particulate matter in the air tend to accumulate on the surface of the air intake filter, forming a blockage layer that obstructs normal airflow. This significantly increases the flow resistance within the air duct, reducing not only the cooling system's heat dissipation efficiency but also decreasing the airflow into the main unit. This, in turn, increases the load on the cooling system and the energy loss of the main unit's intake air, ultimately affecting the overall stability and energy efficiency of the equipment. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a low-loss centrifugal air compressor.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a low-loss centrifugal air compressor, including a base, a traction component at the bottom of the base, and a protective chamber fixedly installed at the top of the base. A centrifugal host is fixedly installed inside the protective chamber, and a volute air intake branch pipe is fixedly installed at the end of the centrifugal host. An air intake unit is detachably connected to one side of the volute air intake branch pipe via a quick-release component. The quick-release assembly includes a first connector, a second connector, a sealing ring, and a fixing sleeve. The first connector is fixedly installed on the side of the air intake branch pipe of the volute, and the second connector is fixedly installed on the side of the air intake unit. A guide plate is fixedly installed on the inner wall of the second connector. A filter plate is snapped into the downstream side of the airflow of the guide plate on the inner wall of the second connector. A bracket is fixedly connected to the inner wall of the second connector between the guide plate and the filter plate. One end of the bracket is fixedly connected to the inner wall of the second connector. The sealing ring is sandwiched between the mating end faces of the first connector and the second connector. The fixing sleeve is sleeved on the circumferential surface of the second connector and is threadedly connected to the first connector for locking and fixing the first connector and the second connector. A steam turbine is rotatably mounted on the side of the guide plate, and a scraper is rotatably mounted on the bracket. One end of the scraper is fixedly mounted on one end of the drive shaft, and the other end of the drive shaft is coaxially and fixedly connected to the steam turbine. The scraper cooperates with the surface of the filter plate for scraping.

[0006] As a further embodiment of this utility model, the surface of the first pair of connectors is provided with a first thread, and the inner wall of the fixing sleeve is provided with a second thread that can cooperate with the first thread, and the first pair of connectors and the second pair of connectors abut against the sealing ring for sealing.

[0007] As a further embodiment of this utility model, the traction assembly includes a traction arm, a wheel body, and a threaded block. The end of the traction arm is rotatably mounted on the bottom of the base, the wheel body is rotatably mounted on both sides of the base, and the threaded block is fixedly mounted in the center of the traction arm.

[0008] As a further embodiment of this utility model, a traction hook is fixedly installed on the side of the traction arm away from the base, and a screw is threadedly connected to the surface of the threaded block.

[0009] As a further embodiment of this utility model, a handwheel is fixedly installed on the top of the screw, and a support foot that can be rotatably installed on the bottom of the screw to abut against the ground.

[0010] Compared with the prior art, the advantages and positive effects of this utility model are as follows: In this invention, by connecting the towing hook to the towing vehicle, the entire machine can be towed and transported to the field construction site. After the machine is in place, turning the handwheel causes the screw to extend downwards, allowing the support legs to contact the ground and support the towing arm, locking the machine in position and preventing it from shifting during operation. During unit operation, the centrifugal main unit continuously compresses air, and the high-pressure gas is delivered to the quick-release assembly through the volute intake branch pipe. The airflow enters the second pair of joints from the first pair of joints, first flowing past the guide plate and impacting the turbine. The airflow pressure drives the turbine to rotate continuously. The turbine drives the scraper on the support to rotate synchronously through the drive shaft, and the scraper moves along the inner side of the filter plate. The circumferential scraping action removes accumulated sand and particles from the filter plate surface in real time, preventing filter plate blockage and increased air intake duct resistance, reducing the main unit's air intake energy consumption, and ensuring stable air intake flow. Furthermore, when the filter plate and scraper are heavily soiled and require deep cleaning, rotating the fixing sleeve and using the threaded connection to disengage the fixing sleeve from the first pair of connectors allows for the separation of the first and second pairs of connectors, enabling quick removal of the internal filter plate and scraper for cleaning and maintenance. After cleaning, the sealing ring is reattached to the two connector end faces, and the fixing sleeve is tightened in the opposite direction to complete the pipeline sealing assembly. The disassembly and assembly operations are simple and require no special tools. Attached Figure Description

[0016] A low-loss centrifugal air compressor, such as Figures 1-5As shown, the system includes a base 1, a traction assembly 5 at the bottom of the base 1, the traction assembly 5 including a traction arm 51, a wheel 52, and a threaded block 53, and a protective chamber 2 fixedly installed on the top of the base 1. A centrifuge host 3 is fixedly installed inside the protective chamber 2, and a volute air intake branch pipe 31 is fixedly installed at the end of the centrifuge host 3. An air intake unit 32 is fixedly installed on one side of the volute air intake branch pipe 31 inside the protective chamber 2. A quick-release assembly 4 is provided between the volute air intake branch pipe 31 and the air intake unit 32. The quick-release assembly 4 includes a first connector 41, a second connector 42, a sealing ring 43, and a fixing sleeve 44.

[0017] To reduce the energy consumption of the main unit's intake and ensure stable intake flow, such as Figure 2-4 As shown, the first connector 41 is fixedly installed on the side of the air intake branch pipe 31 of the volute, and the second connector 42 is fixedly installed on the side of the air intake unit 32; the sealing ring 43 is sandwiched between the mating end faces of the first connector 41 and the second connector 42, and the fixing sleeve 44 is sleeved on the circumferential surface of the second connector 42. The surface of the first connector 41 is provided with a first thread 411, and the inner wall of the fixing sleeve 44 is provided with a second thread 441 that can cooperate with the first thread 411. The first connector 41 and the second connector 42 abut against the sealing ring 43 for sealing. The second thread 441 of the fixing sleeve 44 is threadedly connected to the first thread 411 of the first connector 41 for locking and fixing the first connector 41 and the second connector 42.

[0018] Rotate the fixing sleeve 44 to disengage it from the first connector 41 through the threaded engagement, and then separate the first connector 41 and the second connector 42. Quickly remove the internal filter plate 46 and scraper 471 for cleaning and maintenance. After cleaning, reattach the sealing ring 43 to the two connector end faces and tighten the fixing sleeve 44 in the opposite direction to complete the pipeline sealing assembly. The disassembly and assembly operation is simple and does not require special tools.

[0019] A guide plate 45 is fixedly installed on the inner wall of the second connector 42. A filter plate 46 is snapped into the downstream side of the airflow of the guide plate 45 on the inner wall of the second connector 42. A bracket 47 is fixedly connected between the guide plate 45 and the filter plate 46 on the inner wall of the second connector 42. One end of the bracket 47 is fixedly connected to the inner wall of the second connector 42. A turbine 451 is rotatably mounted on the side of the guide plate 45, and a scraper 471 is rotatably mounted on one side of the bracket 47. The end of the scraper 471 is fixedly mounted on one end of the drive shaft 472. The other end of the drive shaft 472 is coaxially and fixedly connected to the turbine 451. The scraper 471 is engaged with the surface of the filter plate 46 for scraping.

[0020] During unit operation, the centrifugal main unit 3 continuously compresses air. The high-pressure gas is delivered to the quick-release assembly 4 through the volute intake branch pipe 31. The airflow enters the interior of the second pair of connectors 42 through the first pair of connectors 41, and first flows through the guide plate 45 to impact the turbine 451. The airflow pressure drives the turbine 451 to rotate continuously. The turbine 451 drives the scraper 471 on the support 47 to rotate synchronously through the drive shaft 472. The scraper 471 performs a circumferential scraping action along the inner side of the filter plate 46 to remove the sand and dust and particles accumulated on the surface of the filter plate 46 in real time, so as to avoid the filter plate 46 from being blocked and causing the air intake duct resistance to increase, thereby reducing the energy consumption of the main unit's air intake and ensuring stable air intake flow.

[0021] For ease of transport and securing, such as Figure 1 , 5 As shown, the end of the traction arm 51 is rotatably mounted on the bottom of the base 1, the wheel body 52 is rotatably mounted on both sides of the base 1, and the threaded block 53 is fixedly mounted in the center of the traction arm 51; a traction hook 511 is fixedly mounted on the side of the traction arm 51 away from the base 1, and a screw 531 is threadedly connected to the surface of the threaded block 53; a handwheel 532 is fixedly mounted on the top of the screw 531, and a support foot 533 that can abut against the ground is rotatably mounted on the bottom of the screw 531.

After the machine is in place, turn the handwheel 532 to drive the screw 531 to extend downward, so that the support foot 533 is in contact with the ground to support the towing arm 51, lock the position of the whole machine, and prevent the machine from shifting during operation.

[0023] Working principle: By connecting the towing hook 511 of the traction assembly 5 to the towing vehicle, the entire machine can be towed and transported to the field construction site. After the machine is in place, turn the handwheel 532 to extend the screw 531 downwards, so that the support foot 533 is in contact with the ground to support the towing arm 51, locking the position of the entire machine and preventing the machine from shifting during operation. During the operation of the unit, the centrifugal host 3 continuously compresses air. The high-pressure gas is delivered to the quick-release assembly 4 through the air intake branch pipe 31 of the volute. The airflow enters the interior of the second pair of joints 42 through the first pair of joints 41, first flowing through the guide plate 45 to impact the turbine 451. The airflow pressure drives the turbine 451 to rotate continuously. The turbine 451 drives the scraper 471 on the support 47 to rotate synchronously through the drive shaft 472. 71. Perform a circumferential scraping motion along the inner side of the filter plate 46 to remove the sand and dust accumulated on the surface of the filter plate 46 in real time, so as to avoid the filter plate 46 from clogging and causing the air intake duct resistance to increase, reduce the energy consumption of the main unit's air intake, and ensure stable air intake flow. Furthermore, when the filter plate 46 and scraper 471 are heavily soiled and require deep cleaning, rotate the fixing sleeve 44 and use the threaded engagement to disengage the fixing sleeve 44 from the first joint 41, so that the first joint 41 and the second joint 42 can be separated, and the internal filter plate 46 and scraper 471 can be quickly removed for cleaning and maintenance. After cleaning, reattach the sealing ring 43 to the two joint end faces, and tighten the fixing sleeve 44 in the opposite direction to complete the pipeline sealing assembly. The disassembly and assembly operation is simple and does not require special tools.
