[0022] The present invention is described in detail below with reference to the various embodiments shown in the accompanying drawings. However, it should be noted that these embodiments are not limitations of the present invention, and any equivalent transformations or substitutions in functions, methods, or structures made by ordinary technicians in this field based on these embodiments are all within the scope of protection of the present invention.

[0023] Please refer to Figures 1 to 3 A specific embodiment of a lubricating oil tank is disclosed.

[0024] Ginseng Figure 1 and Figure 2As shown, in this embodiment, the lubricating oil tank 100 includes: a tank body 1 for storing oil (i.e., lubricating oil); an electric heater 2 for heating the oil in the tank body 1; a lubricating oil pump 3 for extracting oil from the tank body 1; an explosion-proof device 4 for balancing the air pressure inside and outside the tank body 1; an oil mist blower 5 for extracting oil smoke from the tank body 1; a shaft head pump suction oil return assembly 6 for sucking oil from the tank body 1 or returning it to the tank body 1; and a baffle 7 disposed inside the tank body 1, the baffle 7 is used to separate the inside of the tank body 1 into an oil return area 11 and an oil pump suction area 12. The baffle 7 is as shown in FIG. Figure 2 As shown by the dotted line, the left side of the baffle 7 (as shown Figure 2 The direction indicated by the arrow y1 is the oil return area 11, and the right side of the baffle 7 (as shown in FIG. Figure 2 The direction indicated by the arrow y2 is the oil suction area 12.

[0025] An electric heater 2 heats the oil in the housing 1 to the required operating temperature, ensuring the oil has the appropriate viscosity for easy pumping. A lubricating oil pump 3 extracts the oil from the housing 1 and delivers it to an external device (not shown) requiring lubrication. During delivery, the oil passes through a series of devices (such as a cooler, filter, pressure regulating valve, and temperature control valve, all not shown) to adjust the oil's temperature and pressure to the required levels. An explosion-proof device 4 balances the air pressure inside and outside the housing 1. When the pressure differential between the inside and outside is excessive, it automatically opens to release excess gas or liquid, protecting the housing 1 from damage. An oil mist blower 5 is mounted on the top of the housing 1 to remove oil fumes from the housing 1 and keep the interior clean. An external spindle pump unit (not shown) draws the oil from the housing 1 via a spindle pump oil return assembly 6. This assembly ensures smooth oil flow from and back into the housing 1 during forward and reverse rotation of the external spindle pump unit. When the external oil returns to the tank 1 through the return oil pipeline (not marked), the external oil flows from the high point to the low liquid level inside the tank 1, and foam will be generated. The baffle 7 is arranged inside the tank 1 to separate the return oil area 11 and the pump oil suction area 12, thereby effectively preventing foam from entering the lubricating oil pump 3, reducing noise and ensuring the normal operation of the lubricating oil pump 3.

[0026] The baffle 7 and oil mist blower 5 reduce foam and oil smoke inside the tank 1, thereby improving the overall stability of the lubricating oil tank 100 and reducing the frequency of cleaning and maintenance. The explosion-proof device 4 balances the pressure difference between the inside and outside of the tank 1, reducing the risk of accidents and enhancing safety. The electric heater 2 and the spindle head pump oil return assembly 6 control the oil temperature in the tank 1 and ensure smooth oil flow.

[0027] Ginseng Figure 1 and Figure 3As shown, the shaft head pump oil return assembly 6 includes: several groups of first flange pipes 61 for oil circulation, second flange pipes 62 connected to the first flange pipes 61, and a first pipeline 63 connecting the second flange pipes 62 and the housing 1; in the process of the oil being sucked out of the housing 1 through the first flange pipe 61, part of the oil enters the second flange pipe 62, and the second flange pipe 62 is provided with a one-way valve (not shown) for the oil in the first flange pipe 61 to enter the first pipeline 63. The first flange pipe 61 and the second flange pipe 62 are tightly connected to the housing 1 through flanges to ensure good sealing. The external shaft head pump main unit (not shown) sucks the oil in the housing 1 through the first flange pipe 61, and the second flange pipe 62 is connected to the first flange pipe 61. When the oil is sucked out of the housing 1, the oil flows along Figure 3 The direction indicated by the middle arrow a1 flows in the first flange pipe 61, and part of the oil will flow from the first flange pipe 61 along the Figure 3 The direction indicated by the middle arrow a2 enters the second flange pipe 62 through the second pipe 64. A one-way valve is arranged on the second pipe 64. Then the oil flows along Figure 3 The direction indicated by the middle arrow a3 is that the oil enters the first pipeline 63 from the second flange pipe 62. The first pipeline 63 is used to connect the second flange pipe 62 and the box body 1, so that the oil can flow smoothly back to the box body 1 from the first pipeline 63. The one-way valve can ensure that the oil can only flow from the second flange pipe 62 to the box body 1 and cannot flow in the opposite direction.

[0028] Because the external spindle head pump main unit (not shown) in the prior art extracts oil from the tank 1 in a unidirectional manner, the oil can only be extracted and cannot flow back into the tank 1. Therefore, when the external spindle head pump main unit stops operating and reverses, the oil flows back and cannot flow back into the tank 1, resulting in accumulation in the pipeline. When the external spindle head pump main unit (not shown) stops operating and reverses, the lubricating oil tank 100 ensures that the oil can smoothly flow back into the tank 1 through the first flange pipe 61, thereby preventing the oil from accumulating in the pipeline.

[0029] Ginseng Figure 1 and Figure 2As shown, the shaft head pump oil suction return assembly 6 and the electric heater 2 are arranged in the oil return area 11, and the oil extraction pipeline 31 contained in the lubricating oil pump 3 is connected to the pump suction oil outlet area 12. When the external shaft head pump main unit rotates forward, the shaft head pump oil suction return assembly 6 can ensure that the oil is properly sucked out of the casing 1. When the external shaft head pump main unit reverses, the shaft head pump oil suction return assembly 6 can allow the backflowing oil to smoothly return to the oil return area 11 in the casing 1, avoiding the accumulation of oil in the pipeline, thereby preventing abnormal oil pressure or damage to the equipment. The electric heater 2 heats the oil in the oil return area 11 to ensure that the oil reaches a suitable working temperature. The oil pumping area 12 is separated from the oil return area 11, which can effectively reduce the impact of foam generated when the backflow oil returns to the oil return area 11 on the operation of the lubricating oil pump 3, so that the lubricating oil pump 3 can extract high-quality oil, ensure that the oil is in the best condition, reduce the noise level of the lubricating oil pump 3, and protect the normal operation of the lubricating oil pump 3, reducing the noise and potential damage risks during the operation of the lubricating oil pump 3.

[0030] Ginseng Figure 2 As shown, a notch (not shown) is constructed on the side of the baffle 7 away from the shaft head pump oil return assembly 6 to separate the return oil area 11 and the pump oil suction area 12. The notch ensures that the oil flows between the return oil area 11 and the pump oil suction area 12. The oil flows from the return oil area 11 to the pump oil suction area 12 through the notch, ensuring that the lubricating oil pump 3 can absorb the treated (foam-free) oil. The top surface height of the baffle 7 is higher than the oil level in the box 1. To prevent foam from overflowing from the return oil area 11 to the pump oil suction area 12, since foam usually forms on the surface of the oil, the baffle 7 can serve as a physical barrier to prevent foam from directly passing over the top of the baffle 7.
