Technical Field

[0001] The utility model relates to the technical field of lubricating grease storage, and more specifically, to a lubricating grease storage tank. Background Art

[0002] Grease is mainly used in the friction part of machinery to play the role of lubrication and sealing. It is mainly made of mineral oil (or synthetic lubricant) and thickener. In addition to the basic ingredients, antioxidants, rust inhibitors, anti-wear agents and other additives may also be added to improve its performance. It is suitable for a variety of mechanical equipment, can effectively reduce friction and wear, and improve the working efficiency and life of mechanical equipment.

[0003] Finished grease is usually stored in storage tanks. However, long-term storage of grease is prone to precipitation, making the grease in the tank uneven. In addition, due to the viscous texture of the grease, some of the grease adheres to the tank wall during discharge, which makes discharge and cleaning inconvenient and easily leads to material waste.

The upper end of the grease injection tube cooperates with the sealing cover thread. The inside of the grease injection tube has a funnel-shaped channel with large openings at both ends and a small inner diameter in the middle. The bottom sealing plate and the grease injection tube are hinged by a hinge axis and a torsion spring is arranged at the hinge axis.

DETAILED DESCRIPTION

[0014] The utility model is described in detail below in conjunction with the accompanying drawings.

[0015] Specific embodiment 1 of a grease storage tank of the utility model:

[0016] like Figure 1 As shown, the grease storage tank comprises a tank body 1, a cover body 2 and a stirring and cleaning mechanism. The cover body 2 is installed on the top of the tank body 1 through threads. A grease injection interface is arranged on the cover body 2. The grease injection interface comprises a grease injection tube 3, a sealing cap 4 located outside the grease injection tube 3, and a bottom plate 5 located at the bottom of the grease injection tube 3. The sealing cap 4 is installed through threads to seal the top of the grease injection tube 3. A grease discharge port 17 is opened at the bottom of the tank body 1. The stirring and cleaning mechanism is arranged on the cover body 2, and is mainly composed of a mounting frame 6, a driving motor 8, an electric push rod 7, a central shaft 9, a rotating sleeve 10, a stirring part and a scraper 15. The mounting frame 6 is fixed to the upper part of the cover body 2 and is used to fix the driving motor 8 and the electric push rod 7. A rotating sleeve 10 is rotatably installed in the middle position of the cover body 2 through a sealing ring and a rotating bearing. The output end of the driving motor 8 extends downward and is used to drive the rotating sleeve 10 to rotate. Specifically, a driving gear 11 is disposed at the output end of the driving motor 8 , and a driven gear ring 10 is disposed outside the rotating sleeve 10 . The rotating movement of the rotating sleeve 10 is achieved through the meshing transmission between the driving gear 11 and the driven gear ring 10 .

[0017] The central shaft 9 passes through the rotating sleeve 10 and extends into the tank body 1, and is arranged coaxially with the tank body 1. The rotating sleeve 10 maintains a spline fit with the central shaft 9 to ensure that the central shaft 9 can slide up and down relative to the central shaft 9 while bearing torque. The output end of the electric push rod 7 extends downward and is connected to the upper end of the central shaft 9 through a bearing, so that it can drive the central shaft 9 to rotate and move linearly up and down at the same time. The part of the central shaft 9 extending into the tank body 1 is provided with a stirring part for stirring the grease, and the stirring part includes an open square ring 13 in the shape of "[" and a connecting stirring rod 14. The open square ring 13 includes a vertical part and a horizontal part connected between the two ends of the vertical part and the central shaft. The middle of the inner side of the vertical part of the open square ring 13 is connected to the central shaft through the connecting stirring rod 14, and a scraper 15 is provided on the outer side of the vertical part of the open square ring 13. During the storage of grease, the drive motor 8 and the electric push rod 7 are turned on, and the drive motor 8 drives the central shaft 9 and the stirring part to rotate through the rotating sleeve 10. The electric push rod 7 applies force to the central shaft 9, so that the central shaft 9 rotates and moves up and down at the same time, so as to stir the grease in the tank body in a large range and comprehensively, so as to avoid the grease from being precipitated due to long-term static storage, and at the same time, the grease adhering to the inner wall of the tank body is scraped to prevent it from being difficult to clean due to long-term adhesion; when discharging grease, the grease discharge port is opened, the drive motor 8 and the electric push rod 7 are turned on, and the scraper 15 is used to scrape the grease on the inner wall of the tank body during the grease discharge process, so that the raw materials inside the tank body are discharged cleanly, which is convenient for material discharge and subsequent cleaning, and at the same time reduces material waste.

[0018] The bottom of the tank body is a slope 16 with one side lower and the other side higher. The grease discharge port 17 is located on the lower side of the slope 16. At the end of the discharge, a small amount of grease remaining is guided by gravity to automatically flow to the grease discharge port 17 for discharge, thereby solving the problem that the grease at the bottom is difficult to discharge at the end of the discharge.

[0019] In addition, in the present embodiment, the interior of the grease injection tube 3 has a funnel-shaped channel with large openings at both ends and a small inner diameter in the middle, and the funnel-shaped channel has the effect of gathering materials and evenly distributing the materials; the bottom plate 5 and the grease injection tube 3 are hinged by a hinge shaft and a torsion spring is arranged at the hinge shaft. During grease injection, the bottom plate 5 is flipped down by the gravity of the grease to open the lower opening of the grease injection tube; after the grease injection is stopped, the bottom plate is automatically flipped up by the restoring force of the torsion spring to seal the lower opening of the grease injection tube; in the non-grease injection state, the contact between the grease and the air is minimized to prevent the grease from oxidizing and deteriorating.

[0020] The grease storage tank of the utility model is used so that the electric push rod and the driving motor are turned on during use, so that the central axis drives the stirring part and the scraper to rotate and move up and down at the same time, and the grease is fully stirred from top to bottom, so that the grease is kept uniform everywhere and the occurrence of precipitation is avoided, thereby ensuring the quality of the grease; when discharging the grease, the scraper is used to scrape the grease on the inner wall of the tank body from top to bottom in sequence, thereby reducing the amount of residual oil on the inner wall of the tank body, bringing convenience to discharging and subsequent cleaning, and reducing the amount of grease wasted.

[0021] The above are only preferred implementations of the utility model. The protection scope of the utility model is not limited to the above embodiments. All technical solutions under the idea of ​​the utility model belong to the protection scope of the utility model. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the utility model should also be regarded as the protection scope of the utility model.
