Description

Technical Field

[0001] The utility model relates to the technical field of oil production, and more specifically to an oil refining, impurity removal and preheating device. Background Art

[0002] In the oil refining process, filtering, removing impurities and preheating the crude oil are essential steps, so the filtering effect and efficiency of the crude oil are particularly important in the oil refining process.

[0003] The utility model patent with announcement number: CN219323958U discloses a preheating device for oil refining and impurity removal, which comprises an outer tank body and a filling cover installed at the upper end of the outer tank body, wherein the upper side wall of the outer tank body is connected with a feed pipe, the bottom of the outer tank body is connected with a discharge pipe, an inner tank body is arranged in the outer tank body, a preheating chamber for preheating by circulating hot liquid is arranged between the inner tank body and the outer tank body, a filter assembly for impurity removal and filtration is installed in the middle of the inner tank body, and a pressurizing assembly for pressurizing downward to accelerate oil filtration is arranged above the filter assembly.

[0004] Although the oil refining and impurity removal preheating device is provided with a filtering component to fully filter the oil, the filtering efficiency can be accelerated by cooperating with a pressurizing component.

[0005] However, during the process of filtering oil and fat with this oil refining, impurity removal and preheating device, as oil and fat are continuously added, the impurities accumulated on the filter component will also increase accordingly. Since the impurities are accumulated on the surface of the filter component, the oil and fat containing impurities added from the top needs to penetrate the impurities below and then penetrate downward into the tank body through the filter component. When the holes on the filter component are blocked, it is difficult for the oil and fat above the filter component to penetrate downward into the tank body, thereby reducing the filtering efficiency of the oil and fat. At the same time, since the heat source of the tank body is located in the side wall of the tank body, it is easy to cause the oil and fat in the middle part of the tank body to be difficult to heat, thereby affecting the preheating effect of the oil and fat.

A semicircular baffle is fixedly connected to one end of the discharge barrel 6 away from the loading box 1. The arc wall of the semicircular baffle is fixedly connected to the bottom of the discharge barrel 6, which can effectively prevent the grease at the bottom of the arc groove 5 from flowing out through the discharge barrel 6. During the process of conveying impurities by the spiral conveying plate 15, the spiral conveying plate 15 and the semicircular baffle are squeezed to squeeze out the residual grease in the impurities, thereby reducing the residual grease in the impurities.

[0028] A rectangular through hole 12 is provided on the filter plate 4, and a filter screen 13 is laid on the rectangular through hole 12. The filter plate 4 is arranged at an inclination, and the inclined surfaces of the two upper and lower adjacent filter plates 4 are arranged facing each other, that is, the grease at the lower end of the upper filter plate 4 drips downward onto the upper end of the lower filter plate 4, thereby facilitating the filtering of impurities in the grease, and the hole diameters of the mesh holes on the filter screen 13 decrease successively from top to bottom, thereby facilitating multiple filtering of impurities in the grease.

[0029] At least two rotating shafts 14 are rotatably connected to the inner wall of the loading box 1, one end of the rotating shaft 14 penetrates the side wall of the loading box 1 and extends to the outside of the loading box 1, and a spiral feed plate 15 is fixedly connected to the rotating shaft 14, one end of the spiral feed plate 15 extends into the discharge barrel 6, and the side wall of the spiral feed plate 15 is in contact with the side wall of the arc groove 5, and a plurality of filtering holes are provided at the bottom of the arc groove 5, which is convenient for filtering grease in the impurities collected in the arc groove 5, and the spiral feed plate 15 is convenient for conveying the collected impurities to the outside of the loading box 1.

[0030] A rotating shaft 16 is fixedly connected to the side wall of the circular plate 7 , and the rotating shaft 16 is rotatably connected to the side wall of the loading box 1 , and an end of the rotating shaft 16 penetrates the side wall of the loading box 1 and extends to the outside of the loading box 1 .

[0032] Working principle: The grease that needs to be filtered of impurities is introduced into the filter plate 4 in the loading box 1, and the filter screen 13 on the filter plate 4 blocks the impurities in the grease, and the grease drips downwards through the holes in the filter screen 13 onto the filter plate 4 on the lower side, realizing multi-layer filtration of the grease, further reducing the impurities contained in the grease, and the impurities intercepted on the filter screen 13 slide downwards into the arc groove 5 due to gravity, and the grease in the impurities drips downwards through the through holes at the bottom of the arc groove 5 onto the filter plate 4 on the lower side, and the drive motor 17 and the wires on the heating tube 8 are electrically connected to the power storage device such as a battery, and then the drive motor 17 and the heating tube 8 are started, and the heating tube 8 preheats the filtered grease in the loading box 1 The output shaft of the driving motor 17 drives the pulley 18 to rotate, and the cooperation of the pulley 18 and the belt 19 drives the rotating shaft 16 and the rotating shaft 14 to rotate. The rotating shaft 16 drives the circular plate 7 and the heating tube 8 to rotate during the rotation, and the heating tube 8 stirs the grease in the loading box 1 during the heating process, so that the grease in the loading box 1 is heated more evenly, and the grease is preheated; the rotation of the rotating shaft 14 drives the rotation of the spiral feed plate 15, and the spiral feed plate 15 outputs the impurities accumulated in the arc groove 5 into the loading box 1 through the discharge barrel 6 during the rotation, so as to avoid the accumulation of impurities on the filter screen 13 and cause the mesh to be blocked, thereby ensuring the filtering efficiency of the filter screen 13.

[0033] When the grease in the loading box 1 enters the fixed box 9 through the strip through hole 11, and when the liquid level of the grease in the loading box 1 is higher than the height value of the discharge pipe 10, the heated grease seeps upward through the fixed box 9 and flows out through the discharge pipe 10, thereby realizing the discharge of the preheated grease and ensuring the grease loading capacity inside the loading box 1.

All technical solutions under the concept of the present invention belong to the protection scope of the present invention.
