Description

Technical Field

[0001] The utility model relates to the technical field of lubricating oil production equipment, in particular to a turbine stirrer. Background Art

[0002] In the production process of lubricating oil, it is usually necessary to use a turbine agitator to stir the lubricating oil. After stirring, the blades of the turbine agitator need to be cleaned in time to prevent the lubricating oil from solidifying on the blades. At present, there are two types of turbine agitators on the market. The first type is to weld the stirring blades directly on the disc, and the second type is to open an inclined slot on the disc, insert the stirring blades into the slots and fix them with bolts. The above two types of turbine agitators have the following technical problems:

[0003] The stirring blades of the first type of agitator are directly welded to the disc and cannot be disassembled. Since the stirring blades are usually set at an angle, and the thickness of the stirring blades is very thin, and the gap between adjacent blades near the disc is relatively small, it is easy to scratch the palms of the staff when cleaning the stirring blades in this case, posing a safety hazard. Although the stirring blades of the second type of agitator can be disassembled and cleaned, the edge of the disc needs to be cut and polished to form an inclined slot. This processing process undoubtedly increases the cost of use. The precise cutting of the inclined slot requires high-precision equipment, which is expensive. In addition, the plug-in connection method will cause mechanical wear after multiple disassembly and assembly, resulting in reduced installation accuracy, which will affect the stirring efficiency of the blades. Utility Model Content

DETAILED DESCRIPTION

[0020] The following will disclose multiple embodiments of the utility model with diagrams. For the purpose of clear description, many physical details will be described together in the following description. However, it should be understood that these physical details should not be used to limit the utility model. In other words, in some embodiments of the utility model, these physical details are not necessary. In addition, for the purpose of simplifying the diagram, some conventional structures and components will be depicted in a simple schematic manner in the diagram.

[0021] In addition, the terms "horizontal", "vertical", "overhanging" and the like do not mean that the components are required to be absolutely horizontal or overhanging, but can be slightly tilted. For example, "horizontal" only means that its direction is more horizontal than "vertical", and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0022] In the description of this technology, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this technology can be understood according to specific circumstances.

[0023] In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the fact that ordinary technicians in the field can implement it. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the present utility model.

[0024] See also Figure 1-4The utility model is a turbine agitator, comprising an oil drum 1 and a stirring mechanism, wherein an oil filling nozzle 1 is arranged near the top of the oil drum 1, a sealing cover 4 is arranged on the top of the oil drum 1, a motor 5 is installed on the top of the sealing cover 4, the bottom of the output end of the motor 5 passes through the bottom of the sealing cover 4 and is installed with a coupling 6, the stirring mechanism comprises a connecting sleeve 7, a rotating shaft 11 is inserted at the top of the connecting sleeve 7, the top of the rotating shaft 11 is fixedly connected to the bottom of the coupling 6, a connecting plate 8 is fixedly connected to the surface of the connecting sleeve 7 at an equal distance in an annular manner, a stirring paddle 9 is detachably installed on the surface of the connecting plate 8, and a plurality of oil discharge pipes 3 are installed outside the oil drum 1 and near the bottom.

[0025] In this embodiment, there are four connecting plates 8, the inclination angle between the connecting plates 8 and the connecting sleeve 7 is 30°-60°, and the inclination angle between the stirring paddle 9 and the connecting sleeve 7 is the same as the inclination angle between the connecting plates 8 and the connecting sleeve 7.

[0026] By setting an inclined agitator paddle 9, it is possible to provide the fluid with both circumferential velocity and axial velocity, which is helpful for mixing and stirring the fluid. As the inclination angle increases, the axial velocity provided by the agitator paddle 9 to the fluid will also increase accordingly. This means that at a larger inclination angle, the fluid can be better mixed in the axial direction during the stirring process, thereby achieving a more uniform stirring effect. The increase in the inclination angle will cause the rotation speed of the agitator paddle 9 to decrease accordingly, thereby reducing the energy consumption of the agitator. However, an excessively large inclination angle may cause the degree of rotational motion of the fluid to deteriorate, thereby affecting the stirring effect.

[0027] Further comparison revealed that the 60° inclination angle performed better than the 30° structure in terms of the intensity of internal fluid stirring and mixing, which means that when the 9-blade stirring paddle has an inclination angle of 60°, the fluid mixing effect may be more ideal.

[0028] In this embodiment, four threaded holes are provided on the surface of the connecting plate 8, and a connecting hole is provided on the surface of the stirring paddle 9 at a position corresponding to the connecting hole. A second bolt 10 is installed between the connecting hole and the threaded hole. A countersunk hole 701 is provided at the bottom of the connecting sleeve 7, and a first bolt 702 is arranged in the countersunk hole 701 for fixing the connecting sleeve 7 and the rotating shaft 11. A sealing plug is movably inserted in the countersunk hole 701.

[0029] The above technical solution makes it easy for the staff to disassemble and install the stirring blade 9 and the connecting sleeve 7, thus facilitating the cleaning work.

[0030] Compared with the traditional one-piece turbine agitator, the staff can use tools to easily remove the stirring paddle 9 from the connecting plate 8 for cleaning. It will not be difficult to clean due to the small distance between the stirring paddles 9. The connecting plate 8 has a certain thickness and will not scratch the staff during cleaning. The length of the connecting plate 8 is also short, which is convenient for cleaning. At the same time, compared with the traditional method of cutting the disc and then installing the stirring paddle 9, the setting of the connecting plate 8 does not require positioning cutting, grinding, etc. of the connecting sleeve 7, thereby reducing production costs.

[0031] In this embodiment, the bottom of the inner wall of the oil barrel 1 is spherical in shape, at least two oil drain pipes 3 are provided, and the two oil drain pipes 3 are symmetrically distributed with the center of the oil barrel 1 as the origin. A valve is also installed on the oil drain pipe 3 to control the flow rate during oil discharge.

[0032] In this embodiment, handles 12 are provided on both sides of the top of the sealing cover 4 to facilitate the staff to open the sealing cover 4, and connecting columns 13 are fixedly connected on both sides of the oil drum 1 and near the top to facilitate the staff to lift the oil drum 1 for movement.
