Description
Technical Field
[0001] This utility model relates to the field of pneumatic motor exhaust technology, and in particular to a pneumatic motor exhaust blowing device. Background Technology
[0002] A pneumatic motor, also known as a wind-driven motor, is a device that converts the energy of compressed air into continuous rotational mechanical energy. When a pneumatic motor operates, it requires an external air compressor to inject compressed air into the motor, thus enabling it to operate. The compressed air is then discharged from the motor's exhaust port. While the pneumatic motor itself has a good cooling effect, if the air compressor malfunctions, resulting in high-temperature compressed air entering the motor, the motor temperature will also rise, reducing its lifespan and potentially damaging it. Similarly, a malfunctioning air compressor may also prevent the discharge of compressed air, causing the motor to stop operating and reducing overall work efficiency. Utility Model Content

Detailed Implementation
[0013] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.
[0014] A pneumatic motor exhaust blowing device, such as Figures 1-6 As shown, the device includes a pneumatic motor body 1, on which an air inlet 2 and an air outlet 3 are installed. A flow divider 5 is fixedly connected to the top of the air outlet 3. The flow divider 5 can divide the air discharged from the air outlet 3 into two streams of air. The device also includes a cooling component, an air collecting component, and a sealing component. The cooling component is located between the air inlet 2 and the air outlet 3 and can cool the compressed air. The air collecting component is located on one side of the pneumatic motor body 1 and can store the compressed air. The sealing component is located on the inner wall of the air inlet 2 and is used to seal the air collecting component.
[0015] The cooling assembly includes a cooling shell 4. The cooling shell 4 is fixedly sleeved on the top of the air inlet 2. A first delivery pipe 6 is connected between the air inlet of the cooling shell 4 and the distribution shell 5. An exhaust port is opened on the side of the cooling shell 4 away from the first delivery pipe 6.
[0016] The gas collection assembly includes a second delivery pipe 7. The side of the diverter shell 5 away from the first delivery pipe 6 is connected to the second delivery pipe 7. The bottom of the second delivery pipe 7 is fixedly connected to a gas collection shell 12 bolted to the pneumatic motor body 1. The bottom of the gas collection shell 12 is fixedly connected to an expansion air bladder 16. A first one-way valve 15 is provided at the connection between the bottom of the gas collection shell 12 and the expansion air bladder 16. The top of the expansion air bladder 16 is in contact with the bottom of the pneumatic motor body 1. The top of the expansion air bladder 16 is connected to the side wall of the air inlet 2 via a third delivery pipe 18. It should be noted that the expansion air bladder 16 can be replaced according to the actual situation. The expansion air bladder 16 in the attached figure is in an inflated state filled with gas.
[0017] The gas collection assembly also includes a telescopic cylinder 13. The telescopic cylinder 13 is fixedly installed on one side of the top of the gas collection shell 12. The output end of the telescopic cylinder 13 extends downward and penetrates into the interior of the gas collection shell 12. A compression plate 14 is fixedly installed on the output end of the telescopic cylinder 13. The compression plate 14 is slidably connected to the gas collection shell 12. A second one-way valve 19 is installed on the compression plate 14. The gas collection shell 12 has a large gas collection area, an inclined transition area, and a small gas collection area. The large gas collection area is located at the top, the small gas collection area is located at the bottom, and the inclined transition area is located between the large gas collection area and the small gas collection area. The size of the small gas collection area corresponds to that of the compression plate 14. A pressure detector 17 that is electrically connected to the telescopic cylinder 13 is fixedly connected to the top of the expansion airbag 16.
[0018] The sealing assembly includes a rotating plate 10, which is hinged to the inner wall of the air inlet 2 and connected to the third delivery pipe 18. Torsion springs 11 are connected between the two ends of the rotating plate 10 and the air inlet 2.
[0019] The sealing assembly also includes a baffle 8, which is slidably connected to the inner wall of the air inlet 2 and above the rotating plate 10. A spring 9 is connected between the top of the baffle 8 and the inner wall of the air inlet 2.
[0020] When the pneumatic motor body 1 is ready to operate, an air compressor is connected to the top of the air inlet 2. The air compressor injects compressed air into the air inlet 2. The compressed air enters the pneumatic motor body 1 through the air inlet 2 and drives the pneumatic motor body 1 to operate. Subsequently, the compressed air is discharged from the air outlet 3 into the distribution shell 5. The distribution shell 5 can split the compressed air into two streams. One stream of air is discharged into the cooling shell 4 through the first delivery pipe 6 and contacts the top of the air inlet 2, thereby cooling the compressed air that has just entered the air inlet 2. Then, it is discharged from the exhaust port of the cooling shell 4. It should be noted that due to the operation of the pneumatic motor body 1 itself, the air discharged from the air outlet 3... The air temperature is lower than the temperature of the compressed air entering the air inlet 2, and the air discharged from the air outlet 3 can even make the staff feel "cool". Therefore, the pneumatic motor body 1 itself has a good cooling effect. However, if the air compression device malfunctions, resulting in a high temperature of the compressed air entering the air inlet 2, it will also cause the temperature of the pneumatic motor body 1 to rise, thus causing damage to the pneumatic motor body 1. Therefore, the "cool" air discharged at the air outlet 3 enters the cooling shell 4, which can cool down the compressed air entering the air inlet 2, thereby preventing the temperature of the pneumatic motor body 1 from rising due to the high temperature of the compressed air at the air inlet 2. Another stream of air enters the gas collecting shell 12 through the second delivery pipe 7. At this time, the telescopic cylinder 13 is activated, and the telescopic cylinder 13 performs telescopic reciprocating motion, driving the extrusion plate 14 to move up and down synchronously. When the extrusion plate 14 moves upward, it enters the large gas collecting area of the gas collecting shell 12. The size of the large gas collecting area is larger than the extrusion plate 14, so the gas entering the gas collecting shell 12 from the second delivery pipe 7 can flow downward to the small gas collecting area. When the extrusion plate 14 moves downward, it crosses the large gas collecting area and the inclined transition area and enters the small gas collecting area. Since the size of the small gas collecting area corresponds to the extrusion plate 14, the extrusion plate 14 can block the small gas collecting area, allowing the gas in the large gas collecting area to flow downward. The gas cannot enter the small gas collection area. As the extrusion plate 14 continues to move downward, the gas in the small gas collection area will be compressed and enter the expansion bladder 16 through the first one-way valve 15, causing the expansion bladder 16 to start to expand and increase the gas pressure inside the expansion bladder 16. Then the extrusion plate 14 moves upward and enters the large gas collection area. At this time, the above steps are repeated. It should be noted that because the first one-way valve 15 is provided, the air in the expansion bladder 16 will not flow back into the gas collection shell 12 when the extrusion plate 14 moves upward. At the same time, because the second one-way valve 19 is provided, the gas in the large gas collection area and the inclined transition area will enter the small gas collection area through the second one-way valve 19 when the extrusion plate 14 moves upward. When the internal air pressure of the expansion airbag 16 reaches the preset value set by the pressure detector 17, the pressure detector 17 will release a signal to the telescopic cylinder 13, causing the telescopic cylinder 13 to stop operating. At this time, the amount of air inside the expansion airbag 16 will no longer increase, and the internal air pressure of the expansion airbag 16 will no longer increase. Meanwhile, the air collection shell 12 will be filled with air, and no more air will enter the second delivery pipe 7. Instead, it will enter the first delivery pipe 6, which will increase the cooling effect on the compressed air inside the air inlet 2. Then, it will be discharged from the exhaust port of the cooling shell 4. Initially, the baffle 8 and the rotating plate 10 are not in contact. The rotating plate 10 is tilted downwards, and the baffle 8 is located above the rotating plate 10. When the air compressor delivers compressed air into the air inlet 2, the compressed air will impact the top of the baffle 8, causing the baffle 8 to slide downwards and squeeze the rotating plate 10, causing it to rotate downwards by 45°. At this time, the spring 9 is stretched and the torsion spring 11 stores force. After the rotating plate 10 rotates downwards by 45°, it will be in a vertical state and block the third delivery pipe 18. At this time, the baffle 8 will block the rotating plate 10, thereby preventing the rotating plate 10 from rotating. In the subsequent working process, the air pressure inside the inflatable airbag 16 gradually increases, but because the rotating plate 10 is blocked by the baffle 8, the air inside the inflatable airbag 16 cannot be discharged into the air inlet 2 through the third delivery pipe 18. When the air compressor malfunctions or other external factors prevent compressed air from entering the air inlet 2, the baffle 8 will no longer be impacted by the compressed air. At this time, the spring 9 contracts, causing the baffle 8 to move upward. After the baffle 8 moves upward, it no longer obstructs the rotating plate 10. The torsion spring 11 releases, causing the rotating plate 10 to rotate upward by 45°. After rotating 45°, the rotating plate 10 can no longer rotate and is tilted downward. At this time, the rotating plate 10 no longer blocks the third delivery pipe 18, and the gas in the expansion bladder 16 will enter the air inlet 2 through the third delivery pipe 18. The rotating plate 10 can guide the gas, allowing it to flow downwards into the pneumatic motor body 1, thereby continuing to drive the pneumatic motor body 1 to operate. This prevents the compressed air from failing to enter the air inlet 2 due to external factors, which would cause the pneumatic motor body 1 to stop working. It should be noted that the efficiency and operating time of the gas inside the expansion bladder 16 driving the pneumatic motor body 1 can be changed by replacing the expansion bladder 16. The specific selection of different specifications of expansion bladder 16 needs to be based on the actual situation. While the gas inside the inflatable airbag 16 drives the pneumatic motor body 1, the operator can adjust and repair external factors to allow compressed air to re-enter the air inlet 2. If the compressed air can re-enter the air inlet 2, and the gas inside the inflatable airbag 16 is still driving the pneumatic motor body 1, the compressed air entering the air inlet 2 and the gas inside the inflatable airbag 16 will synchronously drive the pneumatic motor body 1. Furthermore, the gas inside the inflatable airbag 16 will impact the bottom of the rotating plate 10, thus preventing the compressed air in the air inlet 2 from impacting the baffle 8 and causing the baffle 8 to be squeezed. As the rotating plate 10 rotates downwards, the internal air pressure of the inflatable airbag 16 gradually decreases with the increase of operating time. The rotating plate 10 also rotates downwards due to the compression of the baffle 8 until the rotating plate 10 rotates to a vertical position. At this time, the gas inside the inflatable airbag 16 no longer enters the air inlet 2, and the internal air pressure of the inflatable airbag 16 is lower than the preset value set by the pressure detector 17. At this time, the pressure detector 17 sends a signal to the telescopic cylinder 13, causing the telescopic cylinder 13 to reciprocate and extend, thereby causing the compression plate 14 to reciprocate up and down again, and gas is re-injected into the inflatable airbag 16, increasing the air pressure.
[0021] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
