[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] In the description of the present invention, it should be understood that terms such as "opening", "upper", "lower", "thickness", "top", "middle", "length", "inside", "all around" and the like indicating orientation or positional relationship are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the present invention.

[0028] See also Figure 1-4As shown, the utility model is a raw material filling device for producing lubricating oil, comprising a raw material mixing tank 1, a filling tank 2 is provided at the upper end of the raw material mixing tank 1, a tank cover 3 is hinged on the filling tank 2, a filling pipe 4 is connected to the bottom of the filling tank 2, a flow pump 5 is installed on the filling pipe 4, the filling pipe 4 is also interconnected with the inside of the raw material mixing tank 1, a sliding piston 6 is provided inside the filling tank 2, an extension rod 7 connected to the tank cover 3 is provided on the piston 6, the piston 6 can slide out from the upper end of the filling tank 2, and also includes a one-way valve sheet 8 that can realize the opening and closing of the airflow of the piston 6.

[0029] Among them, the tank cover 3 is provided with a guide sleeve 32 for the extension rod 7 to pass through and be slidably connected. The upper end of the extension rod 7 is fixed with a limit block 71 that cooperates with the top of the guide sleeve 32. The limit block 71 is fixed with a handle 72 located outside the tank cover 3. In this embodiment, the extension rod 7 is convenient for manually resetting the piston 6 after the raw material liquid in the filling tank 2 is exhausted.

[0030] Among them, the outer ring of the piston 6 is provided with a sealing ring 61 that can be in sealing contact with the inner side of the filling tank 2 and the tank cover 3. The inside of the piston 6 is also formed with an upwardly formed inner groove 62, and the one-way valve plate 8 is installed on the inner groove 62 through a torsion spring. In this embodiment, the outer ring of the piston 6 is interference fit with the filling tank 2 and the tank cover 3, and the sealing ring 61 is in extrusion contact with the inside of the filling tank 2 and the tank cover 3, thereby forming a sliding seal between the outer ring of the piston 6 and the filling tank 2 and the tank cover 3.

[0031] Among them, a storage cover 33 is provided on the tank cover 3, and an external rod 9 slides through the inside of the storage cover 33, and a connecting rod 10 is hinged between the bottom of the external rod 9 and the upper end of the one-way valve plate 8. The one-way valve plate 8 is hinged at the upper end of the other side that is connected to the inner sink groove 62 through a torsion spring. In this embodiment, the storage cover 33 is used for avoiding the inner sink groove 62, the one-way valve plate 8 and the connecting rod 10. The one-way valve plate 8 fits with the inner sink groove 62 under the action of the torsion spring to form a seal, and the opening direction of the one-way valve plate 8 is upward. When the liquid level inside the filling tank 2 moves down, the one-way valve plate 8 cannot be opened by air pressure, thereby ensuring that the piston 6 slides stably following the liquid level.

[0032] Among them, a limiting seat 21 is fixed to the upper end side of the filling tank 2, and a limiting plate 31 is fixed to the bottom side of the tank cover 3. The tank cover 3 is limited and positioned at an opening and closing angle on the filling tank 2 by the limiting seat 21 and the limiting plate 31. In this embodiment, the limiting seat 21 and the limiting plate 31 can limit the opening and closing angle of the tank cover 3, and at the same time, can form a support after the tank cover 3 is opened, thereby facilitating the filling of raw materials inside the filling tank 2.

[0033] Among them, the outer wall of the filling tank 2 is provided with a glass scale 22 for observing the internal liquid volume. In this embodiment, the glass scale 22 can intuitively know the internal liquid volume of the filling tank 2 and can replenish raw materials in time.

[0034] Among them, a ventilation pipe 34 communicating with the inside and outside is opened at the upper end of the tank cover 3. In this embodiment, the ventilation pipe 34 connects the air between the upper part of the piston 6 and the filling tank 2 and the tank cover 3 with the outside, and can follow the air replenishment or exhaust during the sliding process of the piston 6 to ensure the smooth movement of the piston 6 inside the filling tank 2.

[0035] It can be understood that, firstly, the piston 6 is provided for cleaning the inner wall of the filling tank 2, and the air pressure principle and the flow pump 5 are used to achieve the filling of raw materials and the cleaning of the inner wall of the filling tank 2 at the same time, and the operation of the piston 6 can be facilitated by the extension rod 7. Secondly, a one-way valve sheet 8 is provided on the piston 6 to facilitate the communication or isolation between the liquid and the piston 6 and the air and the outside, so as to facilitate the detachment of the piston 6 and the filling of raw materials.

[0036] A specific application of this embodiment is: Figure 1 As shown, raw material liquid for lubricating oil production is added into the filling tank 2, and the tank cover 3 is covered on the upper end of the filling tank 2 by hinged rotation. At this time, the other end of the hinge between the filling tank 2 and the tank cover 3 can be stably connected by a quick lock or the like, and the one-way valve plate 8 seals the piston 6 under the action of the torsion spring. At this time, the air between the lower end of the piston 6 and the upper part of the liquid is isolated from the outside;

[0037] During use, the raw material liquid in the filling tank 2 is transported to the raw material mixing tank 1 through the flow pump 5 and the filling pipe 4. During the transportation process, the liquid level will move downward. At this time, the liquid will drive the piston 6 to move downward under the action of air pressure. The piston 6 will scrape the residue on the inner wall of the filling tank 2. During the downward movement of the piston 6, the extension rod 7 moves downward outside the guide sleeve 32, and the external rod 9 moves downward in the storage cover 33. Then, the same amount of external air enters between the upper end of the piston 6 and the filling tank 2 and the tank cover 3 through the ventilation pipe 34. The amount of raw materials in the filling tank 2 can be directly observed through the limit seat 21;

[0038] When the raw material is used up, hold the handle 72 and lift the external rod 9 upward. The external rod 9 drives the one-way valve plate 8 to open, and the external rod 9 and the extension rod 7 are moved upward at the same time until the piston 6 is pulled to the inside of the tank cover 3. At this time, the tank cover 3 can be directly opened and the lubricating oil raw material can continue to be added to the filling tank 2.
