Description

Technical Field

[0001] The present invention relates to the technical field of air compressors, and particularly to a multi-rotor air intake type air compressor. Background Art

[0002] An air compressor, also known as an air compressor, is a device used to compress gas. The application range of air compressors is relatively wide, especially in the application on cement tank trucks, and it is an essential component. The air compressors installed on traditional cement tank trucks use the natural air intake method. By pressurizing the gas and storing it in the vehicle's storage tank, a high pressure is formed in the storage tank, and then the storage tank is instantaneously released through a pipeline, so that the materials in the storage tank are transported to the silo in the form of air transportation. The whole process is called ash injection. Through ash injection, the phenomenon of dust flying can be avoided, and the materials can be stored in the silo in sufficient quantity.

[0003] Currently, the cement ash in the cement tank truck needs to be transported to the silo at a higher position with the help of an air compressor. Therefore, a higher power requirement is imposed on the air compressor. A low-power air compressor cannot meet the usage requirements. While a high-power air compressor can make the air pressure in the storage tank meet the requirements, the inflation time each time is too long, usually taking more than one hour to complete inflation, and its working efficiency is low, and it cannot quickly complete ash injection. In addition, a high-power air compressor has a relatively large self-weight, which not only increases the fuel consumption of the cement tank truck, but also undoubtedly imposes an additional burden on a vehicle with limited space resources. Summary of the Invention

[0004] In order to make up for the deficiencies of the prior art, the present invention provides a multi-rotor air intake type air compressor, which has a reasonable structural design and is easy to operate.

The lower end of the air compressor drive shaft 27 passes through the upper air compressor fixing plate 28 and is movably clamped to the lower air compressor fixing plate 28. An air compressor gear 29 is sleeved on the air compressor drive shaft 27 between the two air compressor fixing plates 28. The air compressor gear 29 is matched with the left-handed gear 9 through a transmission member; a rotating cylinder 30 is sleeved on the air compressor drive shaft 27 in the air pressure chamber 26. The front side of the rotating cylinder 30 is closely attached to the front side of the inner wall of the air pressure chamber 26, and there is a gap between the rear side of the rotating cylinder 30 and the rear side of the inner wall of the air pressure chamber 26. A plurality of sliding grooves 31 are uniformly provided on the side wall of the rotating cylinder 30 along its circumferential direction. A telescopic plate 32 is movably clamped in each sliding groove 31. A plurality of positioning holes 33 are respectively provided in the inner ends of the telescopic plates 32 along their height directions from top to bottom. Springs 34 are provided in each positioning hole 33. The outer ends of the telescopic plates 32 are provided with rounded corners and are tightly abutted against the inner wall of the air pressure chamber 26.

[0033] Optionally, the rotating cylinder 30 is movably sleeved on the air compressor drive shaft 27. A limiting block 35 is vertically provided on the air compressor drive shaft 27 along its height direction.

[0034] Optionally, filter plates 37 are respectively provided at the air inlet and air outlet of the air compressor. A plurality of ventilation holes 38 are respectively provided in the filter plates 37 to improve the stability when the air flow enters and prevent the local air flow from being too large and affecting the normal operation of the air compressor.

[0035] Optionally, the air compressor drive shaft 27 passes through the air pressure tank 25 upward and is movably clamped to the support plate 39 on the top of the air pressure tank 25, further improving the rotation stability of the air compressor drive shaft 27.

[0036] Optionally, the transmission member includes right transmission fixing plates 40 symmetrically provided on the upper and lower sides of the inner wall of the air compressor drive box 2. A right transmission shaft 41 is vertically and movably clamped between the two right transmission fixing plates 40. A right transmission gear 42 is sleeved on the right transmission shaft 41. The left side of the right transmission gear 42 meshes with the left-handed gear 9, and the right side of it meshes with the air compressor gear 29.

[0037] Optionally, a dust-proof cover 43 is movably clamped on the air inlet at the top of the air guide cover 11, and a plurality of air inlet holes 44 are provided on the dust-proof cover. This prevents sundries from entering the air guide cover 11 through the air inlet, thus avoiding damage to the left cyclone blade 5 and the right cyclone blade 10.

[0038] Optionally, the diameters of the upper and lower ends of the air guide cover 11 are both lower than the diameter at its middle position. The design with the upper and lower ends of the air guide cover 11 being thinner and the middle being thicker can effectively increase the air guiding effect, enabling the air to enter the elbow 14 more smoothly and reducing the air resistance.

[0039] Before using this device, it is necessary to install the device on the vehicle and drive the driving gear 15 to rotate through the motor. At the same time, connect the air outlet of the air compressor to the storage tank of the vehicle through a pipeline. When in use, start the motor to work. The driving gear 15 drives the driving gear 17 to rotate through the rotating shaft 16. On the one hand, the driving gear 17 drives the lower transmission gear 21 to rotate, thereby driving the upper transmission gear 22 to rotate through the left transmission shaft 20, and further driving the right-handed gear 7 to rotate. As the right-handed gear 7 rotates, it drives the blower sleeve 6 to rotate radially, thereby driving the right cyclone blade 10 to rotate clockwise. On the other hand, the driving gear 17 drives the left-handed gear 9 to rotate, and further drives the blower main shaft 3 to rotate radially, thereby driving the left cyclone blade 5 to rotate counterclockwise. It should be noted that the left cyclone blade 5 and the right cyclone blade 10 rotate in opposite directions, thus effectively sucking air from the air inlet of the air guide cover 11 and making it quickly enter the elbow 14 along the air guide cover 11, effectively preventing the air in the air guide cover 11 from discharging out of the air inlet again. A large amount of air can be collected in a short time. The function of the collar 12 is on the one hand to fix the position of the air guide cover 11, and on the other hand, it also plays a role in limiting the rotation of the blower main shaft 3 to prevent deviation.

[0040] When the wind enters the air compressor from the elbow 14, the driving shaft 27 of the air compressor is powered by the right transmission gear 42. As the driving shaft 27 of the air compressor rotates, it drives the rotating cylinder 30 to rotate, and then drives each telescopic plate 32 to rotate. When each telescopic plate 32 rotates, the telescopic plate 32 near the front side of the inner wall of the air storage tank 25 contracts into the corresponding chute 31. At this time, each spring 34 in the telescopic plate 32 tightens in its positioning hole 33, while the telescopic plate 32 near the rear side of the inner wall of the air storage tank 25 extends out under the support of the elastic force of each spring 34 on the telescopic plate 32, so that it tightly abuts against the inner wall of the air compression chamber 26, thus avoiding air leakage. The air flow entering the air storage tank 25 is quickly compressed and then discharged into the storage tank from the exhaust port of the air compressor. Even when using a low-power air compressor on a cement tanker, it can easily complete the inflation process of the storage tank, and can greatly shorten the entire inflation time, shortening the original inflation time of more than one hour to minutes, greatly improving work efficiency and the ash discharging effect. It not only reduces fuel consumption, but also improves the space utilization rate of the vehicle, reduces unnecessary burdens, and solves many problems existing in the prior art.
