Description

Technical Field

[0001] The utility model relates to the technical field of oil processing, in particular to a solid-liquid mixer used for oil refining. Background Art

[0002] When oils and fats are refined, solid powders are usually used as adsorbents. The adsorbents are mainly used to adsorb free fatty acids and phospholipids in crude oils or to decolorize crude oils, thereby effectively removing harmful substances in crude oils.

[0003] The utility model patent with patent application publication number CN 214973739 U discloses a solid-liquid mixer for oil refining, including a stirring tank and a quantitative feeder, the quantitative feeder includes a hopper and a discharger, the discharger includes a discharger shell and a discharge wheel, a plurality of fan-shaped plates are evenly arranged on the discharge wheel, the fan-shaped plates and the discharger shell are tightly matched to form a plurality of airtight spaces, the airtight spaces are capacity bins, an air suction port is provided on the discharger shell, and the air suction port is connected to a vacuum pump.

[0004] The utility model is a solid-liquid mixer for oil refining. When solid powder needs to be charged, the solid powder can be sucked into the capacity bin through vacuum negative pressure, which can effectively avoid the bridging phenomenon when the solid powder is unloaded and improve the measurement accuracy.

[0005] However, the above device still has some shortcomings in actual use. The most obvious one is that when the powder falls from the feed port to the inner wall of the mixing tank, it is very easy to form a clumping phenomenon under the coating of the crude oil. Although the clumping powder can be broken up by using a stirring rod later, this operation will lead to a longer crude oil processing time and have a significant impact on the crude oil processing efficiency.

[0006] Therefore, it is necessary to invent a solid-liquid mixer for oil refining to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0020] 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.

[0021] The utility model provides Figure 1-2 A solid-liquid mixer for oil refining is shown, comprising a mixing tank 1, a powder supply mechanism 2 is arranged on the top of the mixing tank 1, a stirring mechanism 3 is arranged inside the powder supply mechanism 2, and a lifting centrifugal dispersion mechanism 4 is arranged on the top of the stirring mechanism 3.

[0022] It should also be noted that the powder supply mechanism 2 is a solution that has been disclosed in the prior art and is not an essential technical feature of the present application, so the present application does not elaborate on its specific structure.

[0023] like Figure 1 As shown, the stirring mechanism 3 includes a driving motor 31, a reciprocating screw 32, a rotating disk 33 and a stirring rod 34, wherein the driving motor 31 is fixedly arranged at the bottom of the mixing tank 1, the reciprocating screw 32 passes through the bottom of the mixing tank 1 and is transmission-connected to the driving motor 31, the rotating disk 33 is fixedly sleeved at the outer bottom of the reciprocating screw 32, and a plurality of stirring rods 34 are provided, and the plurality of stirring rods 34 are evenly fixedly arranged at the top of the rotating disk 33.

[0024] By setting the above structure, the grease to be treated can be added into the mixing tank 1 through the pipe on the left top of the mixing tank 1, and the driving motor 31 is started at the same time. The driving motor 31 drives the reciprocating screw 32 to rotate continuously. When the reciprocating screw 32 rotates, it drives multiple stirring rods 34 to rotate through the rotating disk 33, thereby stirring the grease.

[0025] like Figure 2 As shown, the lifting centrifugal dispersion mechanism 4 includes a square shaft 41, a dispersion disc 42, a threaded sleeve 43, a limit rod 44, a limit slider 45 and a limit slide 46, wherein the square shaft 41 is slidably nested at the top of the reciprocating screw 32, the dispersion disc 42 is fixedly arranged at the top of the square shaft 41, the threaded sleeve 43 is rotatably arranged at the bottom of the dispersion disc 42 through a bearing and is arranged on the outside of the reciprocating screw 32 through a reciprocating threaded transmission sleeve, the limit rod 44 is fixedly arranged on the side of the threaded sleeve 43, the limit slider 45 is fixedly arranged at the end of the limit rod 44, the limit slide 46 is opened on the inner wall of the mixing tank 1, and the limit slider 45 is slidably arranged on the inner side of the limit slide 46.

[0026] By setting the above structure, during the stirring process, the powder supply mechanism 2 continuously adds powder to the top of the dispersion plate 42. Due to the rotation of the reciprocating screw 32, the threaded sleeve 43 drives the dispersion plate 42 to repeat the lifting operation, and the square shaft 41 drives the dispersion plate 42 to rotate synchronously, so that the dispersion plate 42 can sprinkle the powder during the rotation and lifting process, so that the powder is evenly mixed into the continuously stirred oil. Compared with the same type of device in the prior art, the powder can be more evenly mixed into the oil, avoiding the agglomeration of the powder under the coating of the crude oil, improving the efficiency of the crude oil processing, and shortening the time required for the crude oil processing.

[0027] Working principle of this utility model:

[0028] During actual use, the grease to be treated is added into the mixing tank 1 through the pipe on the top left side of the mixing tank 1, and the driving motor 31 is started at the same time. The driving motor 31 drives the reciprocating screw 32 to rotate continuously. When the reciprocating screw 32 rotates, the rotating disk 33 drives the multiple stirring rods 34 to rotate, thereby stirring the grease.

[0029] During the stirring process, the powder supply mechanism 2 continuously adds powder to the top of the dispersion disk 42. Due to the rotation of the reciprocating screw 32, the threaded sleeve 43 drives the dispersion disk 42 to repeat the lifting operation, and the square shaft 41 drives the dispersion disk 42 to rotate synchronously, so that the dispersion disk 42 sprinkles the powder during the rotation and lifting process, so that the powder is evenly mixed into the continuously stirred oil.

[0030] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
