Description

[0047] The liquid storage mechanism comprises a liquid storage tank 26, a pressurizing pump 27 and a pressurizing tank 28. The pressurizing tank 28 is connected with the pressurizing pump 27 and communicates with the liquid storage tank 26 through a pipeline. A main switch 29 is arranged on the pipeline communicating the pressurizing tank 28 with the liquid storage tank 26. The liquid storage tank 26 is communicated with a plurality of liquid inlet pipes 30 corresponding to the jet pipes 13 in the control units. The liquid inlet pipes 30 on the liquid storage tank 26 are all provided with liquid stopping clamps (not shown in the figure).

[0048] The specific working principle is as follows:

[0049] Firstly, the staff pushes the hand pushing handle 8 on the fixed frame 4 to move the fixed frame 4 on the cylindrical guide rail 3 to the vertical position above the waste oil collecting channel 11. Then, the plurality of oil buckets 1 to be cleaned are inverted on the plurality of oil bucket fixing stations on the fixed frame 4, so that the outer side cylinder wall of the oil bucket 1 is in contact with the inner arc surface of the arc-shaped supporting plate 5. Then, according to the width size of each oil bucket 1, the limiting baffle 6 is inserted into the limiting slot 9 in the oil limiting station on both sides of the oil bucket 1 and is in contact with the outer side cylinder wall of the oil bucket 1, so as to separate and fix the plurality of oil buckets 1. At this time, the waste oil in the plurality of oil buckets 1 is poured into the waste oil collecting channel 11 to realize waste oil pouring and collecting.

[0050] Then, the staff pulls the hand pushing handle 8 to move the fixed frame 4 on the cylindrical guide rail 3 to the vertical position above the cleaning liquid collecting channel 12. The fixed frame 8 simultaneously abuts and contacts the plurality of control units and pushes the screw rod 19 to move axially along the cylindrical guide rail 3. Since the screw rod 19 is threadedly connected with the push rod 18 and the T-shaped sliding block 22 on the push rod 18 is embedded in the T-shaped slot 21 on the fixed plate 14, the screw rod 19 moves under the pushing action of the fixed frame 4, and at the same time, the push rod 18 also moves together with the screw rod 19 under the auxiliary guiding action between the T-shaped sliding block 22 and the T-shaped slot 21. This causes the push wheel 20 on the push rod 18 to slide on the side of the swing rod 23 away from the bottom of the fixed plate 14 from the hinge between the swing rod 23 and the fixed plate 14 towards the direction of the guide sliding head 24, and constantly compresses the buffer spring 15, so that the guide sliding head 24 on the swing rod 23 moves along the arc of the arc-shaped sliding groove 16 on the fixed plate 14. The guide sliding head 24 can drive the arc-shaped jet pipe 13 on the fixed block 25 to extend into the corresponding oil bucket 1 during the sliding process.

[0051] When the injection pipes 13 in the control units are inserted into the oil tank 1, the staff holds the push handles 8 and keeps them still, so that the fixed frame 4 and the screw rods 19 in the control units are in abutting contact. Then, the staff releases any one of the push handles 8, opens the total switch 29 between the pressurizing tank 28 and the liquid storage tank 26 and the pressurizing pump 27, and opens the liquid stopper on the liquid inlet pipe 30 corresponding to the injection pipes 13 inserted into the oil tank 1, so that the cleaning liquid in the liquid storage tank 26 is sprayed onto the inner wall of the oil tank 1 through the liquid inlet pipe 30 and the injection pipes 13 under the action of the pressurizing pump 27, to clean the inside of the oil tank 1. The cleaned cleaning liquid flows into the cleaning liquid collection channel 12 from the tank opening of the oil tank 1, to be collected and treated.

[0052] After the cleaning is completed, the staff closes the total switch 29, the pressurizing pump 27 and the corresponding liquid stopper, and releases the push handles 8. The buffer spring 15 loses the force and returns to the original position, the swing rod 23 drives the guide sliding head 24 to slide reversely in the arc-shaped sliding groove 16 under the elastic force of the buffer spring 15, so that the injection pipes 13 are separated from the oil tank 1, and the fixed frame 4 is pushed and separated from the screw rod 19 under the transmission of the push wheel 20, the push rod 18, the T-shaped slot 21 and the T-shaped sliding block 22. The structure in each control unit returns to the original position. Then, the limiting baffle 6 is taken out from the limiting slot 9 of each oil tank limiting station, and each cleaned oil tank 1 is taken out from each oil tank fixing station.

[0053] The above description of disclosed embodiments enables those skilled in the art to carry out or use the present application. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present application. Therefore, the present application will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
