DETAILED DESCRIPTION OF THE EMBODIMENTS
[0021] The following further describes in detail the specific embodiments of the present utility model in conjunction with the accompanying drawings and embodiments. The following embodiments are used to illustrate the present utility model, but are not used to limit the scope of the present utility model.
[0022] As Figures 1 to 3 shown, the exhaust device with integrated oil control function provided by the embodiment of the present utility model includes an exhaust straight cylinder 1. A screw port 2 for connecting to the exhaust port of the exhaust device is fixedly connected to the bottom end of the exhaust straight cylinder 1. A top cover 5 is movably connected to the top end of the exhaust straight cylinder 1. The top cover 5 includes a frustum 5-1 and a straight cylinder 5-2. The diameter of the top surface of the frustum 5-1 is larger than the diameter of the bottom surface of the frustum 5-1. The straight cylinder 5-2 is fixedly connected to the bottom surface of the frustum 5-1. The diameter of the bottom surface of the frustum 5-1 is equal to the diameter of the straight cylinder 5-2. The diameter of the top surface of the frustum 5-1 is larger than the outer diameter of the exhaust straight cylinder 1. The diameter of the straight cylinder 5-2 is smaller than the inner diameter of the exhaust straight cylinder 1. A connecting body 3 is fixedly connected to the bottom end of the straight cylinder 5-2. A cone 8 is fixedly connected to the bottom end of the connecting body 3. A spiral chute 6 is provided on the cone 8. A plurality of top cover exhaust holes 4 are provided on the top cover 5. The top cover exhaust holes 4 extend from the bottom surface of the straight cylinder 5-2 to the top of the frustum 5-1 and are higher than the top surface of the exhaust straight cylinder 1. A plurality of cone exhaust holes 7 that penetrate from the middle of the cone 8 to its top surface are provided on the cone 8.
[0023] Among them, the exhaust device can be the shaft bearings of the main exhaust fan of the sintering machine, the shaft bearings of the motor, the gearbox and bearings of the wind turbine, the industrial compressor, the equipment in the metallurgical industry such as rolling mills and blowers, the ball mills and rotary kilns in the cement production line, and various types of speed reducers and thin oil stations.
[0024] When the exhaust device with integrated oil control function provided by the embodiment of the present invention is in use, screw the screw port 2 onto the exhaust port of the exhaust device, and place the top cover 5 on the exhaust straight tube 1. At this time, a connected space is formed between the present utility model and the exhaust port. When the bearings and gears inside the exhaust device rotate, due to the effect of mechanical movement, the oil-gas mixture will be driven and overflow outwards from the exhaust port; when the oil-gas mixture overflows to the cone 8, the heavy oil droplets and the oil droplets condensed from part of the gas will flow back to the inside of the exhaust device along the spiral slideway 6, realizing the oil control function, and the remaining gas continues to exhaust upwards through the cone exhaust holes 7. After part of the gas overflows to the top cover 5 and the connecting body 3, due to cooling and deceleration, it condenses into oil droplets and flows back to the inside of the exhaust device along the outer wall of the connecting body 3, the cone exhaust holes 7 and the spiral slideway 6, realizing the recycling of oil, and the remaining weak gas is discharged along the top cover exhaust holes 4, which not only reduces the waste of oil, but also reduces the amount of harmful gases discharged into the atmosphere.
[0025] In summary, the working principle of the exhaust device with integrated oil control function provided by the embodiment of the present invention is: through the method of physical separation, the oil-gas mixture generated during the operation of the exhaust device is separated to achieve the purpose of saving oil and reducing emissions.
[0026] The exhaust device with integrated oil control function provided by the embodiment of the present invention has the following characteristics:
[0027] 1. By fixedly connecting the bottom surface of the exhaust straight tube 1 to the screw port 2, it is realized to be connected to the exhaust port of the exhaust device in the form of a screw thread, ensuring firm and reliable connection. 2. By setting the top cover exhaust holes 4 extending from the bottom surface of the straight cylinder body 5-2 to the top of the frustum 5-1 and higher than the top surface of the exhaust straight tube 1, the top cover exhaust holes 4 are in an inclined state, which can not only ensure the smooth discharge of oil and gas, but also enable the generated oil stains to flow back, solving the problem of oil leakage, and at the same time can prevent dust from entering the inside of the device and causing equipment wear. 3. By opening a spiral slideway 6 on the cone 8, the splashed grease can drip back to the inside of the exhaust device along the cone tip by itself, effectively reducing the loss of grease. 4. By opening cone exhaust holes 7 on the cone 8, the oil and gas can be discharged along the cone exhaust holes 7 to the upper space of the structure to continue to agglomerate oil droplets, and the remaining gas is discharged along the top cover exhaust holes 4. 5. The top cover 5 and the cone 8 are connected by a connecting body 3 with a cylindrical structure, which is beneficial to the backflow of oil droplets.
[0028] In another embodiment, the exhaust device with integrated oil control function further includes a lock nut 9 and an O-ring 10. The bottom end of the lock nut 9 is provided with a washer groove, the O-ring 10 is stuck in the washer groove, and the lock nut 9 is threadedly connected to the screw port 2. Specifically, the lock nut 9 can be a hexagonal lock nut.
[0029] When this embodiment is in use, screw nut 9 is screwed onto the top end of screw thread 2. Then, O-ring washer 10 is stuck in the washer groove, and they are screwed onto the exhaust port of the exhaust device as a whole and then tightened with screw nut 9. Screw nut 9 has an internal screw thread and is tightened with screw thread 2 to ensure that exhaust straight tube 1 will not become loose during operation. By providing washer groove 10, the O-ring washer can be tightly clamped, increasing the sealing performance of the entire device, avoiding the deformation and deviation of O-ring washer 10 during the tightening process of screw nut 9, which may cause secondary leakage of oil stains, and at the same time enabling the utility model to be more tightly connected to the exhaust device.
[0030] In another embodiment, cone 8, connecting body 3 and top cover 5 are integrally formed. Integral forming not only makes the overall structure relatively strong, but also can avoid oil stain leakage caused by the gaps in the split design.
[0031] In another embodiment, the number of top cover exhaust holes 4 is four, and the four top cover exhaust holes 4 are evenly distributed along the circumference. By setting it like this, uniform and high-efficiency exhaust can be achieved.
[0032] In another embodiment, the number of cone exhaust holes 7 is four, and the four cone exhaust holes 7 are evenly distributed along the circumference. By setting it like this, uniform and high-efficiency exhaust can be achieved.
[0033] In a specific embodiment, the length of exhaust straight tube 1 is 130 mm, the outer diameter is 50 mm, and the inner diameter is 38 mm; the outer diameter of screw thread 2 is 45 mm and the height is 30 mm; the diameter of the top surface of cone 8 is 38 mm and the cone height is 40 mm; the diameter of spiral chute 6 is 3 mm; the diameter of cone exhaust hole 7 is 3 mm; the diameter of the top surface of frustum 5-1 is 60 mm, the diameter of the bottom surface is 34 mm, and the sum of the heights of frustum 5-1 and straight cylinder 5-2 is 15 mm; the diameter of connecting body 3 is 20 mm and the height is 40 mm; the diameter of top cover exhaust hole 4 is 4 mm. The inner diameter of screw nut 9 is 45 mm, the height is 5 mm, and the cross-sectional diameter of washer groove 10 is 2.5 mm; the cross-sectional diameter of the ring of O-ring washer is 2.5 mm and the inner diameter of the ring is 45 mm.
[0034] By setting the length of exhaust straight tube 1 to 130 mm, the overall device has a moderate length, thus avoiding the influence on maintenance due to excessive length and the easy splashing of oil droplets due to too short length. It can reduce the impact force of the grease hitting the wall during high-speed rotation, thereby reducing the ejection of grease.
[0035] In another embodiment, O-ring washer 10 is made of rubber material to increase the elasticity of the O-ring washer and enhance the sealing performance. O-ring washer 10 has a ring structure, which can reduce leakage caused by deformation during the tightening process of screw nut 9.
[0036] The exhaust device provided by the embodiments of the present invention can effectively separate the oil-gas mixture generated during the operation of mechanical equipment, effectively solve the problem of oil leakage, realize the recycling of oil, reduce the waste of oil and environmental pollution, reduce the maintenance cost of the exhaust equipment, be both economical and environmentally friendly, improve the operation efficiency and stability of the exhaust equipment, and thus improve the production efficiency.
[0037] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. It should be noted that for those of ordinary skill in the art in the technical field, without departing from the technical principle of the present utility model, several improvements and modifications can be made, and these improvements and modifications should also be regarded as the protection scope of the present utility model.
