[0026] The technical solutions in the embodiments of the present utility model will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts shall fall within the protection scope of the present utility model.

[0027] The present utility model provides: a cleaning device for large bearings by spray method, as Figures 1-6 shown, which includes a spray working box 1. An atomization disk 5 is movably installed inside the spray working box 1. An oil injection pipe 6 is connected and installed at the top end of the atomization disk 5. The oil injection pipe 6 extends out from inside the spray working box 1, and a pressurized air pipe 8 is connected and installed at the position of the oil injection pipe 6 outside the spray working box 1 through a connecting bellows 7. A control box 11 is fixedly installed at the bottom of the spray working box 1. A rotating placement disk 13 is rotatably installed at the top end of the control box 11. An annular protection pipe 14 is movably installed on the upper part of the rotating placement disk 13. The atomization disk 5 is movably in contact with the annular protection pipe 14. An air compression box 15 is installed at the bottom of the control box 11. Filters 16 are installed through both sides of the air compression box 15. A draw plate 18 is movably installed inside the air compression box 15. A filter box 20 is arranged on the upper part of the draw plate 18. A porous filter material 22 is filled in the filter box 20. An air collecting box 23 is installed at the top end of the filter box 20. An air supply pipe 25 is connected and installed at the rear side of the air collecting box 23. The air supply pipe 25 penetrates through the air compression box 15 and is connected and installed with the pressurized air pipe 8.

[0028] Preferably, a rotating door 2 is rotatably installed on the front side of the spray working box 1. A driving box 3 is installed at the top end of the spray working box 1. Two groups of electric push rods 4 are arranged at the output end of the driving box 3. The electric push rods 4 penetrate through the spray working box 1 and are installed, and the telescopic ends of the electric push rods 4 are bolted to the atomization disk 5. The rotating door 2 installed on the front side of the spray working box 1 ensures that the atomization rust removal process will not be affected by the outside. The driving box 3 installed at the top end of the spray working box 1 controls the telescopic movement of the electric push rods 4, thereby ensuring the lifting of the atomization disk 5, so that the atomization disk 5 can be used in contact with the annular protection pipe 14 to avoid the splashing of atomized rust removal oil.

[0029] Furthermore, a sliding groove 9 is formed through the rear side of the spray working box 1. A limit sleeve 10 is slidably installed inside the sliding groove 9. The oil injection pipe 6 extends out from inside the limit sleeve 10. The sliding groove 9 formed on the rear side of the spray working box 1 limits the limit sleeve 10, and the oil injection pipe 6 extends out from inside the limit sleeve 10, so that when the electric push rod 4 works to control the lifting of the atomizing disc 5, it can ensure the movement of the oil injection pipe 6. At the same time, since the oil injection pipe 6 and the pressurized air pipe 8 are connected through the connecting bellows 7, after the pressurized air pipe 8 is connected to the air supply pipe 25, its position can remain unchanged, while the oil injection pipe 6 can be lifted independently to complete the continuous supply to the atomizing disc 5.

[0030] Furthermore, a protection seat 12 is installed at the top end of the control box 11. A motor is arranged inside the control box 11. The output end of the motor is key-connected with a rotating shaft, and the rotating shaft extends out from inside the protection seat 12 and is key-connected with the rotating placement disc 13. The motor inside the control box 11 controls the rotation of the rotating placement disc 13, so that the air compression box 15 can better perform the atomizing rust removal work on the placed bearings. At the same time, the annular protection pipe 14 can be disassembled and placed, so that the staff can clean the rotating placement disc 13 and the annular protection pipe 14 well, and can also place and take the bearings better.

[0031] It should be noted that a limit seat 19 is bolted to the upper surface of the draw plate 18. The filter box 20 is installed on the upper surface of the limit seat 19. A set of connection ports 21 are respectively installed on the left and right sides of the filter box 20 corresponding to the two side filter meshes 16. The connection ports 21 slide and dock with the filter meshes 16. The limit seat 19 bolted to the upper surface of the draw plate 18 limits the filter box 20, so that after the draw plate 18 is pushed into the air compression box 15, the connection ports 21 can correspond to the filter meshes 16, and the air is filtered through the cooperation of the filter meshes 16 and the porous filter material 22, greatly improving the quality of the atomizing rust removal oil.

[0032] Specifically, two air pumps 24 are bolted to the top end of the filter box 20. The air suction ends of the two air pumps 24 are hermetically installed deep inside the filter box 20, and the output ends of the air pumps 24 extend into the air collecting box 23 and are hermetically installed. The operation of the air pumps 24 greatly increases the air suction volume to complete the pressurization and delivery of the air, and the pressurization operation is completed through the air collecting box 23.

[0033] In addition, a limit protection pipe 17 is installed through the rear side of the air compression box 15 corresponding to the position of the air supply pipe 25. The air supply pipe 25 extends out from inside the limit protection pipe 17. A one-way air valve 26 is installed at the position of the air supply pipe 25 inside the air compression box 15. The limit protection pipe 17 limits the air supply pipe 25, and the installed one-way air valve 26 prevents gas from flowing back and ensures the stability of gas delivery.
