[0030] This utility model proposes a sand circulation device 2 for use in an aircraft horizontal stabilizer shaft processing equipment 100.

[0031] Please see Figures 1 to 3 In one embodiment of this utility model, the aircraft horizontal stabilizer shaft processing equipment 100 further includes a sandblasting device 1 and a dust removal device 3. The sand circulation device 2 includes a sand storage mechanism 21, a separation mechanism 22, and a fan 23. The sand storage mechanism 21 includes a sand storage tank 211 and a sand quantity control valve 212 disposed on the sand storage tank 211. The sand storage tank 211 stores sand. The sand quantity control valve 212 is connected to the sandblasting device 1 through a conveying pipe. The sand storage tank 211 is usually used to fill high-pressure gas to deliver sand to the sandblasting device 1. The sandblasting device 1 uses high-speed jetting sand to sandblast the inner and outer walls of the aircraft horizontal stabilizer shaft. The separation mechanism 22 includes a recovery floor 221 and a cyclone separator 222. The recovery floor 221 has a collection trough 221a. The recovery floor 221 is disposed below the sandblasting device 1 to collect the waste generated during the sandblasting process. The waste is a mixture of sand and dust.

[0032] Cyclone separator 222 is located above sand storage mechanism 21 and is connected to recovery floor 221 and dust removal device 3. The lower end of cyclone separator 222 is connected to sand storage tank 211. Fan 23 is connected to cyclone separator 222 and sandblasting device 1. When fan 23 is working, it can generate negative pressure in the entire equipment to suck sandblasting waste into cyclone separator 222. Cyclone separator 222 can separate sand and dust from sandblasting waste and recover the sand to sand storage tank 211. Fan 23 transports the separated dust to dust removal device 3 for processing. The sand recycling device 2 proposed in this utility model can continuously recover sand and separate dust, with high recovery efficiency.

[0033] It should be noted that in this embodiment, the sandblasting device 1, the recycling floor 221, the cyclone separator 222, and the dust removal device 3 can be connected through closed pipes, or the devices can be interconnected, or there can be closed channels between the devices for the fan 23 to draw air and generate negative pressure. The specific structure can be designed according to actual needs and is not specifically limited here, as long as the fan 23 can generate negative pressure and transport the sandblasting waste to the cyclone separator 222. The abrasive is generally brown corundum, but quartz sand, steel grit, etc., can also be used, and this is not specifically limited here.

[0034] like Figures 1 to 3As shown, in one embodiment of this utility model, the sand recycling device 2 further includes a waste conveying pipe 24 and a dust removal pipe 25. Specifically, the two ends of the waste conveying pipe 24 are respectively connected to the recycling floor 221 and the cyclone separator 222. The cyclone separator 222 is located above the recycling floor 221. The negative pressure generated by the fan 23 is used to drive the sandblasting waste to flow upward along the height direction and enter the cyclone separator 222. The cyclone separator 222 separates the sandblasting waste into sand and dust. The lower end of the cyclone separator 222 is connected to the sand storage tank 211. The sand is recycled into the sand storage tank 211 under the action of gravity.

[0035] Furthermore, the cyclone separator 222 is also connected to the dust removal device 3 via a dust removal pipe 25. A fan 23 is mounted on the dust removal device 3 and connected to the waste conveying pipe 24 and the dust removal pipe 25. The dust separated by the cyclone separator 222 enters the dust removal device 3 along the dust removal pipe 25 under the action of the fan 23. It is understandable that the cyclone separator 222 is directly connected to the sand storage tank 211, and through the waste conveying pipe 24 and the dust removal pipe 25, rapid separation of sand and dust can be achieved, eliminating the need for manual recycling and effectively avoiding sand waste. This results in higher automation efficiency for the sandblasting process of aircraft horizontal stabilizer shafts.

[0036] like Figure 4 As shown, in one embodiment of this utility model, the cyclone separator 222 is provided with a dust outlet 222a, a feed inlet 222b, and a discharge outlet 222c sequentially from top to bottom along the height direction. Specifically, the feed inlet 222b is connected to the waste conveying pipe 24, the dust outlet 222a is connected to the dust removal pipe 25, and the discharge outlet 222c is connected to the sand storage tank 211. Sandblasting waste enters the cyclone separator 222 along the waste conveying pipe and is separated. Under the action of gravity, the sand falls into the sand storage tank 211 through the discharge outlet 222c, while the dust rises upward under the action of wind and enters the dust removal pipe 25 through the dust outlet 222a. It can be understood that the cyclone separator 222 can efficiently separate sand and dust and achieve automatic sand recovery, avoiding the inefficient method of manual recovery.

[0037] like Figure 4 As shown in one embodiment of this utility model, the cyclone separator 222 is further provided with a filter element 26. Specifically, the filter element 26 is located between the feed inlet 222b and the discharge outlet 222c to collect larger debris and waste materials for regular cleaning, preventing them from entering the sand storage tank 211 and clogging the sandblasting device 1. It should be noted that the filter element 26 can be made of metal mesh, multi-layer screen, etc., as long as it can effectively filter debris.

[0038] like Figure 4As shown, in one embodiment of this utility model, the filter element 26 is configured as a sand collection hopper 261. An installation port is provided on the side wall of the cyclone separator 222 between the inlet 222b and the outlet 222c. The sand collection hopper 261 is inserted into the cyclone separator 222 through the installation port to filter the falling sand. It is understood that by providing the sand collection hopper 261 and the installation port, operators can quickly remove the screened impurities and reinstall the cleaned sand collection hopper 261 back into the cyclone separator 222.

[0039] like Figure 2 As shown, in one embodiment of this utility model, the shape of the recycling floor 221 matches the shape of the sandblasting device 1. The collection trough 221a of the recycling floor 221 has its opening facing upwards, and the collection trough 221a has a flared structure from bottom to top. A small discharge hole is opened at the bottom of the collection trough 221a. After the sandblasting waste enters the collection trough 221a, it flows to the discharge hole. Under the action of the blower 23, the sandblasting device 1 has air intake at the top and air outlet at the bottom, so that the sandblasting waste is sucked from the discharge hole into the waste conveying pipe 24 and enters the cyclone separator 222. It can be understood that the shape of the collection trough 221a is an inverted pyramid structure with a discharge hole at the bottom, which can ensure that the blower 23 generates sufficient negative pressure to convey the sandblasting waste upwards along the waste conveying pipe 24 to the cyclone separator 222, which helps to reduce the operating power of the blower 23.

[0040] like Figure 5 As shown, in one embodiment of this utility model, the sand storage mechanism 21 further includes a pressure regulating valve 213, an air supply pipeline 214, and an exhaust valve 215 disposed on the sand storage tank 211. The pressure regulating valve 213 is used to connect with an external air source to control the air pressure inside the sand storage tank 211. When sand needs to be supplied, the pressure regulating valve 213 is opened and high-pressure gas is introduced. When the sand in the sand storage tank 211 is used up, the pressure regulating valve 213 can be closed and the exhaust valve 215 can be opened to discharge the high-pressure gas in the sand storage tank 211. Furthermore, the sand storage tank 211 is also provided with a four-way valve 217, which is used to connect the pressure regulating valve 213, the air supply line 214 and the pressure indicator. The pressure regulating valve 213 is connected to the air supply line 214 through the four-way valve 217. The sand quantity control valve 212 is connected to the lower end of the sand storage tank 211 and the end of the air supply line 214 away from the four-way valve 217. The high-pressure gas in the air supply line 214 is used to spray the sand in the sand quantity control valve 212 to the conveying pipe and into the sandblasting device 1.

[0041] like Figure 1As shown, in one embodiment of this utility model, the sandblasting device 1 has a first spray gun 11 and a second spray gun (not shown). The first spray gun 11 is located at the top of the sandblasting device 1 and is used to move into the sandblasting device 1 to sandblast the inner wall of the aircraft horizontal stabilizer shaft. The second spray gun is located inside the sandblasting device 1 and is used to sandblast the outer wall of the aircraft horizontal stabilizer shaft. Figure 5 As shown, the sand storage mechanism 21 includes two sand quantity control valves 212 and two air supply lines 214. The two sand quantity control valves 212 are respectively connected to the sand storage tank 211, and the two air supply lines 214 are respectively connected to the four-way valve 217 and the two sand quantity control valves 212. The two sand quantity control valves 212 are connected to the first spray gun 11 and the second spray gun through two material conveying pipes. Each sand quantity control valve 212 is used to control the sand flow rate of the corresponding spray gun.

[0042] Furthermore, after the abrasive in the sand storage tank 211 is used up, the pressure regulating valve 213, the sand quantity control valve 212, and the air control valve 2141 of the air supply pipeline 214 can be closed sequentially. Finally, the exhaust valve 215 can be opened. When the compressed air in the tank is exhausted, the cone valve at the top of the sand storage tank 211 will automatically fall, and the sand separated by the cyclone separator 222 will flow back to the sand storage tank 211 for recycling. It can be understood that by setting two sand quantity control valves 212 to connect the first spray gun 11 and the second spray gun respectively, the processing efficiency of the aircraft horizontal stabilizer shaft can be improved.

[0043] like Figure 5 As shown, in one embodiment of the present invention, the sand storage mechanism 21 further includes an air filter 216 connected to the pressure regulating valve 213. The air filter 216 is used to filter out impurities such as moisture in the air entering the sand storage tank 211 to ensure that clean and dry air enters the sand storage tank 211.

[0044] This utility model also proposes an aircraft horizontal stabilizer shaft processing equipment 100, which includes a sandblasting device 1, a dust removal device 3, and a sand circulation device 2. The specific structure of the sand circulation device 2 is as described in the above embodiments. Since this aircraft horizontal stabilizer shaft processing equipment 100 adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0045] The above description is merely an exemplary embodiment of the present utility model and does not limit the scope of protection of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the scope of protection of the present utility model.
