[0079] Therefore, the system is used in the spray dust reduction system or the spray system working with liquid liquid (water or additive) as medium, and is used on the operation machine of the railway screening operation. The screening machine digs out the ballast on the sleeper bottom, excavates, and then screens and backfills the track bed, so that a large amount of dust is generated. The spray dust reduction technology is adopted to cover the excavating area, the backfilling area, the ballast falling area and the vibrating screen area, so that the dust can be effectively reduced and the operation environment can be improved. The second pump body 6 on the screening machine can be started after receiving the water pressure signal of the water inlet, water is delivered to each nozzle through pressure, atomized water mist is sprayed out from the nozzle, and each area plays a dust reduction role.

[0085] In another embodiment, the first pump body 2 is a centrifugal water supply pump, and the second pump body 6 is a high-pressure water pump. The centrifugal water supply pump is installed above the screening machine frame 1 and below the main soil belt. The centrifugal water supply pump inlet communicates with the first water tank 4, and the centrifugal water supply pump outlet communicates with the second water tank 7.

[0086] In actual use, first, through the control button, the high-pressure water pump is controlled to work, the high-pressure water pump sucks water in the second water tank 7, the water is pressurized by the high-pressure water pump and then delivered to each sprayer of the dust suppression device 9 through the pipeline, and the water mist is sprayed through the sprayer, thereby playing a dust suppression role. When the water in the second water tank 7 reaches a low water level, the second liquid level detection device 77 provided on the second water tank 7 has a low water level alarm function, the water level alarm is associated with the centrifugal water supply pump, and the alarm information is fed back to the control device. After receiving the signal, the control device will make the centrifugal water supply pump work, and the centrifugal water supply pump will suck water to the first water tank 4 and supplement water to the second water tank 7.

[0087] When the water in the two water tanks is insufficient, the first liquid level detection device 48 and the second liquid level detection device 77 will send alarm information to the control device, and after receiving the signal, the control device will make the centrifugal water supply pump and the high-pressure water pump stop working, thereby avoiding the water pump from idling and protecting the water pump.

[0088] As described above, the water tanks are installed on the QS-650K screen cleaner itself to avoid the problem that the screen cleaner cannot be installed with water tanks due to space limitations, and to provide a water source for the dust suppression system and meet the water demand.

[0089] In addition, after the dust suppression system is installed, dynamic and static analysis is performed to ensure that the installation of the dust suppression system does not affect the vehicle dynamics and the strength of the vehicle frame. Through dynamic calculation and analysis, the critical speed of the vehicle under the conditions of empty and full water tanks after the installation of the dust suppression system is 152 km / h, the instability critical speed of the snake motion is greater than the required hitching speed; the maximum values of the front and rear driver's room transverse and vertical accelerations are less than the standard requirements; the front and rear driver's room transverse and vertical stability indicators in the speed range of 50-100 km / h are "excellent"; in summary, the installation of the water tanks does not affect the dynamic performance of the vehicle. Through static analysis of the vehicle frame, the frame tolerance value before the installation of the water tanks is 26.086 mm, and the frame tolerance value after the installation of the water tanks is 26.859 mm. It can be seen that the installation of the two water tanks has a small effect on the frame tolerance value. The equivalent stress value of the frame before the installation of the water tanks reaches 256.62 MPa, and after the installation of the water tanks, the equivalent stress value of the frame reaches 268.751 MPa, which increases by 12.131 MPa, which is a small increase, and is less than the allowable stress of the material 309 MPa. It can be seen that after the installation of the water tanks, in terms of strength, the strength of the frame meets the standard requirements.

[0090] The system retains the necessary components of the dust suppression system, provides a water source from the water tank, does not need to rely on external water supply, simplifies the structure of the equipment, improves the reliability of the equipment, and avoids the risk of affecting the normal operation of the equipment due to insufficient water source; the high-pressure water pump is used to suck water from the water tank, pressurize the water, and deliver the water to the spraying equipment, and the atomizing nozzle can effectively control the spraying intensity and spraying range, thereby avoiding waste of water resources; the low water level alarm and water pump association module are provided to protect the water pump when the water quantity is insufficient and the water flow does not reach the plunger pump inlet.
