Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0024] Please see Figures 1-5 As shown, an oil blending device for an atmospheric pressure storage tank includes a base 1, and a blending assembly 2 is provided on the top of the base 1. The blending assembly 2 includes a first mixing chamber 21, a suction pipe 29 is fixedly installed on one side of the first mixing chamber 21, the other end of the suction pipe 29 is fixedly installed at the input end of a first pump 31, a delivery pipe 32 is fixedly installed at the output end of the first pump 31, a filter 33 is fixedly installed at the other end of the delivery pipe 32, an inlet pipe 34 is fixedly installed on one side of the back of the filter 33, a control channel 35 is fixedly installed at one end of the inlet pipe 34, a first return oil pipe 39 is fixedly installed on one side of the control channel 35, one end of the first return oil pipe 39 is fixedly installed to a second return oil pipe 41 through a tee, one end of the second return oil pipe 41 is fixedly installed at the input end of a second pump 42, a connecting pipe 43 is fixedly installed at the output end of the second pump 42, the other end of the connecting pipe 43 is fixedly installed on one side of the first mixing chamber 21, and the inlet pipe 34 is connected to the first return oil pipe 39 and the input pipe 36 respectively.

[0025] During operation, the first pump 31 starts and draws oil from the first mixing chamber 21 through the suction pipe 29. The oil is then transported to the filter 33 through the delivery pipe 32 to remove impurities. The filtered oil enters the control channel 35 through the inlet pipe 34. When the solenoid valve 38 in the control channel 35 opens the first return oil pipe 39, the oil enters the second pump 42 through the first return oil pipe 39 and the second return oil pipe 41, and is then pumped back to the first mixing chamber 21 through the connecting pipe 43, forming a circulating mixture. At the same time, the first servo motor 22 drives the first stirring paddle 23 to stir, achieving multi-dimensional mixing.

[0026] Furthermore, the blending assembly 2 also includes a second mixing chamber 24. An input pipe 36 is fixedly installed on one side of the second mixing chamber 24. The input pipe 36 is used to transport oil into the inner cavity of the second mixing chamber 24. The input pipe 36 is fixedly installed on one side of the control channel 35. An output pipe 37 is fixedly installed on the control channel 35. The other end of the output pipe 37 is fixedly installed on one side of the second mixing chamber 24. The output pipe 37 is used to draw oil out of the inner cavity of the second mixing chamber 24.

[0027] During operation, if staged blending is required, the solenoid valve 38 of the control channel 35 switches to the input pipe 36 passage. The filtered oil enters the second mixing chamber 24 through the input pipe 36. The second servo motor 25 drives the second stirring paddle 26 to perform preliminary stirring of the oil in the second mixing chamber 24. Then, the output pipe 37 draws the preliminarily mixed oil back to the control channel 35 and merges it with the circulating oil in the first mixing chamber 21 to achieve staged blending.

[0028] Furthermore, a second return oil pipe 41 is fixedly installed on one side of the control channel 35, and a solenoid valve 38 is electrically connected to one side of the control channel 35.

[0029] During operation, the solenoid valve 38 controls the flow of oil through electrical signals, and can switch between single-compartment circulating blending or dual-compartment staged blending modes to meet the blending needs of different oils.

[0030] Furthermore, a first servo motor 22 is fixedly installed on the top of the first mixing chamber 21, a first stirring paddle 23 is fixedly installed on the output end of the first servo motor 22, and a first chamber cover 27 is threadedly connected to the top of the first mixing chamber 21.

[0031] During operation, the first servo motor 22 drives the first stirring paddle 23 to rotate, stirring the oil in the first mixing chamber 21. Combined with the circulating flow through the pipeline, this improves the uniformity of mixing. The first chamber cover 27 is removable for easy maintenance and cleaning.

[0032] Furthermore, a second servo motor 25 is fixedly installed on the top of the second mixing chamber 24, a second stirring paddle 26 is fixedly installed on the output end of the second servo motor 25, and a second chamber cover 28 is threadedly connected to the top of the second mixing chamber 24.

[0033] During operation, the second servo motor 25 drives the second stirring paddle 26 to stir the oil in the second mixing chamber 24, achieving the initial mixing in the graded blending process.

[0034] Furthermore, the base 1 includes a support frame 11, a first mixing chamber 21 and a second mixing chamber 24 are fixedly installed on the top of the support frame 11, an mounting frame 12 is fixedly installed on the top of the support frame 11, and four casters 13 are fixedly installed on the bottom of the support frame 11.

[0035] During operation, the casters 13 facilitate the movement of the device and adapt to the mixing requirements of different storage tanks; the mounting bracket 12 can be used to fix equipment components and improve structural stability.

[0036] Working principle: The oil is driven by the first pump 31 and the second pump 42 to circulate between the mixing chamber and the control channel. Impurities are removed by the filter 33. At the same time, the mechanical stirring of the first agitator 23 and the second agitator 26 is used to achieve multi-dimensional blending by combining pipeline circulation mixing and in-chamber stirring. This solves the problem of uneven mixing in traditional equipment. The oil flow direction can be switched by the control channel 35 and the solenoid valve 38. The single-chamber circulation or double-chamber stage blending mode can be flexibly selected to meet the personalized blending process of different component oils and improve the adaptability and blending efficiency of the equipment.
