Abstract
Description
Technical Field
[0001] This utility model relates to the field of white oil treatment technology, specifically to a white oil blending tank. Background Technology
[0002] Currently, most existing white oil blending tanks use a single type of agitator, such as a standard paddle agitator, which can only generate a unidirectional flow of agitation. This results in insufficient mixing of the white oil within the tank and the presence of dead zones. This is particularly problematic for blending high-viscosity white oils or those with multiple added ingredients, making it difficult to achieve uniform mixing and affecting the quality stability of the white oil product. When the white oil blending process changes, such as blending white oils of different viscosities or proportions, existing agitation systems struggle to flexibly adjust the agitation methods and parameters. The fixed structure of the agitator and the single speed setting cannot meet diverse blending needs, limiting the application range and production flexibility of the blending tanks. Utility Model Content
[0003] The purpose of this invention is to provide a white oil mixing tank to address the aforementioned deficiencies.
[0004] A white oil blending tank includes a blending tank body. The top of the blending tank body is provided with a white oil refined material inlet and an auxiliary material inlet. The bottom of the blending tank body has a conical structure and a blending material outlet is provided at the lowest point. The top of the blending tank body is also provided with a breather valve A for balancing the pressure inside the tank. The flange of the outlet pipe of the breather valve A is connected to the flange of the flame arrester B.
[0005] It also includes a stirring and blending mechanism disposed within the mixing tank, the stirring and blending mechanism comprising a central shaft stirring paddle assembly and a side stirring paddle assembly;

[0007] The side-entry agitator assembly includes two sets of side-entry agitators symmetrically arranged on the side wall of the mixing tank. The rotation shaft of the side-entry agitator extends into the interior of the mixing tank and has a propulsion blade at its top.
[0008] Preferably, there are four upper horizontal stirring rods and four middle inclined stirring rods, which are evenly distributed around the stirring shaft. The middle inclined stirring rods are inclined upwards or downwards and have an angle of 60-70° with the stirring shaft.
[0009] Preferably, the number of the lower anchor-type stirring rods is two pairs and they are arranged perpendicular to each other.

[0019] In the description of the embodiments of this utility model, it should be noted that if terms such as "upper," "lower," "inner," or "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the utility model product is in use, they are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the utility model. Furthermore, if terms such as "first" or "second" appear in the description of this utility model, they are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.
[0020] In the description of the embodiments of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0021] As shown in the attached figure, a white oil blending tank includes a blending tank body 30. The top of the blending tank body 30 is provided with a white oil refined material inlet 31 and an auxiliary material inlet 32. The bottom of the blending tank body 30 has a conical structure and a blending material outlet 33 is provided at the lowest point. The top of the blending tank body 30 is also provided with a breather valve A40 for balancing the pressure inside the tank. The flange of the outlet pipe of the breather valve A40 is connected to the flange of the flame arrester B41.
[0022] It also includes a stirring and blending mechanism disposed within the blending tank 30, the stirring and blending mechanism comprising a central shaft stirring paddle assembly and a side stirring paddle assembly;
[0023] The central shaft stirring paddle assembly includes a blending motor 34 located at the top center of the blending tank 30, a stirring shaft 35 connected to the output shaft of the blending motor 34 and extending into the blending tank 30, and an upper horizontal stirring rod 36, a middle inclined stirring rod 37, and a lower anchor stirring rod 38 mounted on the stirring shaft 35. The stirring shaft is vertically arranged at the center of the tank, and multiple layers of different types of stirring blades are installed on the shaft. The uppermost layer is a flat-blade stirring paddle (upper horizontal stirring rod), used to initially disperse the white oil and auxiliary raw materials that have just entered the tank. The middle layer is an inclined-blade stirring paddle (middle inclined stirring rod), which generates axial and radial mixing flow, enhancing the vertical circulation and lateral diffusion of white oil in the tank. The bottommost layer is an anchor stirring paddle (lower anchor stirring rod), close to the bottom of the tank, to prevent white oil from depositing at the bottom of the tank and to ensure that the white oil in all parts of the tank is fully stirred.
[0024] The side-entry agitator assembly includes two sets of side-entry agitators 39 symmetrically arranged on the side wall of the mixing tank 30. The rotation shaft of each side-entry agitator 39 extends into the mixing tank 30, and its top is equipped with a propeller blade 42. Multiple side-entry agitators with propeller blades are installed on the side wall of the tank, and their rotation direction coordinates with the central shaft agitator assembly to form a complex three-dimensional mixing flow field, further improving mixing efficiency and mixing uniformity. The side-entry agitators are driven by independent motors, and their rotation speed can be adjusted according to the mixing process requirements.
[0025] In another technical solution, there are four upper horizontal stirring rods 36 and four middle inclined stirring rods 37, evenly distributed around the circumference of the stirring shaft 35. The middle inclined stirring rods 37 are inclined upwards or downwards at an angle of 60-70° to the stirring shaft 35. The four stirring rods evenly distributed around the circumference make the mixing of white oil and auxiliary additives more uniform.
[0026] In another technical solution, the number of the lower anchor-type stirring rods 38 is two pairs and they are arranged perpendicular to each other, so as to make the white oil and auxiliary additives deposited at the bottom of the tank more thoroughly mixed.
[0027] In another technical solution, the number of each group of side-entry agitators 39 is no less than two. This creates a complex three-dimensional mixing flow field, further improving mixing efficiency and mixing uniformity.
[0028] In another technical solution, the propulsion blade 42 does not come into contact with the central shaft stirring paddle assembly.
[0029] In another technical solution, one or more grounding wires with good conductivity are provided between the mixing tank 30 and the ground to conduct static electricity to the ground and prevent static electricity accumulation from causing fire or explosion accidents.
[0030] The above-described embodiments are only intended to illustrate the technical solution and features of this utility model, and are intended to enable those skilled in the art to implement them. They should not be used to limit the scope of protection of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model are within the scope of protection of this utility model.
