DETAILED DESCRIPTION

[0032] At present, when oil is used in industry, it is contained in oil drums, which are generally made of iron or plastic in a cylindrical shape. When taking oil, it is usually done manually, and the oil is taken from the top of the drum. The bottom of the drum is flat. After the oil is taken, some residual oil often remains at the bottom of the drum and cannot be used up. Oil is usually of high value. If the residual oil in the drum is not recycled, it will accumulate and cause a huge waste of resources.

[0033] 1 ton of crude oil can be used to refine 50 kg of lubricating oil, while 1 ton of waste oil can be used to refine 700-900 kg of lubricating oil. In addition, the waste oil regeneration process is simple, with low investment and fast returns. It is an important link in saving and fully utilizing oil resources and improving the economic benefits of industrial and mining enterprises.

[0034] If the residual oil is not recovered but discharged directly, only a small amount of the oil can be decomposed by organisms, so improper disposal will cause harm to the natural environment; for example, discharging waste oil into any water body will reduce the oxygen that aquatic plants and animals rely on for survival. In addition, if the oil is burned without any control, harmful gases and harmful combustion residues will be produced, which will also cause serious pollution to the atmosphere and land.

[0035] The existing residual oil recovery methods all adopt manual dumping of oil barrels to take out the residual oil. This collection method has the problems of low efficiency, low collection rate, and easy splashing on the ground.

[0036] In view of the above problems, the present invention provides an oil barrel residual oil collection device 100, which can improve the residual oil collection efficiency and reduce the residual oil residue in the oil barrel, thereby avoiding oil waste and avoiding residual oil discharge, which is beneficial to environmental protection.

[0042] It should be noted that, in the absence of conflict, the features in the embodiments of the present invention may be combined with each other.

[0043] Please refer to Figure 1-Figure 5 The present embodiment provides an oil barrel residual oil collection device 100, which includes an oil collecting box 110, a turning assembly 120, an oil barrel placement rack 130 and a rotating assembly 140;

[0044] The oil collecting tank 110 is provided with an oil inlet 111; the oil barrel placing rack 130 is connected to the flip assembly 120, and the flip assembly 120 is used to drive the oil barrel placing rack 130 to flip relative to the oil collecting tank 110, so that the oil barrel can be flipped to the top of the oil collecting tank 110, and the remaining oil in the oil barrel flows to the oil inlet 111;

[0045] The rotating assembly 140 is connected to the oil barrel rack 130 and is used to drive the oil barrel placed on the oil barrel rack 130 to rotate around its axis direction to adjust the position of the oil outlet of the oil barrel relative to the oil inlet 111.

[0046] Please refer to Figure 1-Figure 5 The working principle of the oil barrel residual oil collection device 100 is:

[0047] The oil drum residual oil collection device 100 comprises an oil collecting box 110, a turning assembly 120, an oil drum placement rack 130 and a rotating assembly 140; the oil collecting box 110 is provided with an oil inlet 111;

[0048] The oil barrel residual oil collection device 100 adopts an inverted oil barrel so that the oil outlet of the oil barrel faces downward, so that the residual oil in the oil barrel can flow through the oil outlet toward the oil inlet 111 of the oil collecting tank 110, thereby playing the role of collecting the residual oil; in this process, the inverted oil barrel is in an inverted state, that is, it is tilted or inverted relative to the oil collecting tank 110, and the residual oil flowing out of its oil outlet will flow into the oil inlet 111;

[0049] Specifically, the oil barrel rack 130 is connected to the flip assembly 120, and the flip assembly 120 is used to drive the oil barrel rack 130 to flip relative to the oil collecting tank 110, so that the oil barrel can be flipped to the top of the oil collecting tank 110, and the remaining oil in the oil barrel flows to the oil inlet 111; and the rotating assembly 140 is connected to the oil barrel rack 130, and is used to drive the oil barrel placed on the oil barrel rack 130 to rotate around its axis direction, so as to adjust the position of the oil outlet of the oil barrel relative to the oil inlet 111;

[0050] Therefore, in the process of collecting the residual oil, the oil barrel residual oil collection device 100 can flip the oil barrel placement rack 130 through the flipping assembly 120, and then adjust the position of the oil barrel on the oil barrel placement rack 130, so that it is flipped from an upright state to an inverted or tilted state, that is, the oil outlet of the oil barrel is downward or toward the oil inlet 111 of the oil collecting tank 110, so that the residual oil guided out of the oil outlet can flow into the oil collecting tank 110 toward the oil inlet 111; in the aforementioned process, in order to improve the collection efficiency of the residual oil, and on the basis of the oil outlet being opened on the top of the existing oil barrel, The residual oil in the oil barrel can quickly flow to the oil collecting box 110 through the oil outlet. Therefore, the oil barrel residual oil collection device 100 is also equipped with a rotating assembly 140, which is used to rotate the oil barrel placed on the oil barrel placement rack 130 around its axis. The purpose of this method is to adjust the oil outlet to the lowest position by rotating the oil barrel when the oil barrel is in an inclined or inverted oil outlet state. That is, this setting method can enable most of the residual oil in the oil barrel to be discharged through the oil outlet, thereby reducing the residual oil residue and improving the collection efficiency of the residual oil.

[0051] In summary, the oil barrel residual oil collection device 100 can improve the residual oil collection efficiency and reduce the residual oil residue in the oil barrel, thereby avoiding oil waste and avoiding the discharge of residual oil, which is beneficial to protecting the environment.

[0052] For further information, please refer to Figure 1-Figure 5 In this embodiment, in order to protect the oil inlet 111 and prevent debris in the environment from entering the oil collecting tank 110 through the oil inlet 111, the oil barrel residual oil collection device 100 includes an oil baffle plate 112 movably connected to the oil collecting tank 110, and the oil baffle plate 112 has a position for opening or blocking the oil inlet 111;

[0053] When the oil baffle plate 112 is at a position to open the oil inlet 111 , it is inclined relative to the oil inlet 111 to guide the oil from the oil barrel to flow toward the oil inlet 111 .

[0054] That is, through the above-mentioned structural setting, the oil inlet 111 can be sealed by the oil baffle plate 112 to prevent debris in the environment from entering the oil collecting tank 110 through the oil inlet 111. When the residual oil needs to be collected, the oil inlet 111 can be opened to guide the oil to prevent the oil from splashing outside the oil collecting tank 110 during the residual oil collection process.

[0055] For further information, please refer to Figure 1-Figure 5 In this embodiment, in the process of collecting the residual oil in the oil barrel, in order to improve the collection efficiency, when the residual oil in the oil barrel is large, the oil can be extracted to improve the collection efficiency. Therefore, the residual oil collection device 100 for the oil barrel further includes an oil pump 171 and an oil extraction pipe 172. The oil extraction pipe 172 is used to transport the oil in the oil barrel to the oil collection tank 110, or to transport the oil in the oil collection tank 110 to the oil barrel. By setting the oil pump 171 and the oil extraction pipe 172, two-way oil guidance can be achieved, that is, the oil in the oil barrel can be transported to the oil collection tank 110, or the oil in the oil collection tank 110 can be transported to the oil barrel, so that the residual oil in the oil barrel can be conveniently guided to the oil collection tank 110, and when the amount of oil in the oil collection tank 110 is large, it can be conveniently guided out for use.

[0056] It should be noted that, in order to monitor the amount of oil in the oil collecting tank 110 , the oil collecting tank 110 is provided with a visual oil level observation window.

[0057] Please refer to Figure 1-Figure 5 In the present embodiment, it can be known from the above content that the present embodiment adopts a flipping oil drum placement rack 130, so that the oil drum is inverted, and its oil outlet is facing downward, so that the residual oil inside can be quickly discharged. Based on this, since the flipping of the oil drum will drive the position of its oil outlet to change during the flipping process, in order to make the residual oil discharged through its oil outlet flow to the oil inlet 111 during the flipping process of the oil drum, the oil drum residual oil collection device 100 also includes a sliding assembly 150, the sliding assembly 150 is connected to the oil collecting box 110, the flipping assembly 120 is connected to the sliding assembly 150, and the sliding assembly 150 is used to drive the flipping assembly 120 to slide relative to the oil collecting box 110, so that the oil outlet of the oil drum is close to or away from the oil inlet 111.

[0058] That is, through such a setting, during the turning process of the oil drum, the sliding assembly 150 can drive the turning assembly 120 to slide relative to the oil collecting box 110, so that the oil outlet of the oil drum is close to or away from the oil inlet 111, and then the oil outlet can be adjusted relative to the oil inlet 111, so that the residual oil flowing out of the oil outlet can flow to the oil inlet 111, thereby reducing the residual oil from being led out to the area outside the oil inlet 111, so as to improve the recovery rate of the residual oil;

[0059] Specifically, the sliding assembly 150 includes a slide rail 151, a slide table 152, and a sliding drive 153; the slide rail 151 is connected to the oil collecting box 110, the slide table 152 is slidably matched with the slide rail 151, and the sliding drive 153 is used to drive the slide table 152 to slide relative to the slide rail 151; wherein, the flip assembly 120 is connected to the slide table 152. Thus, when the oil barrel placing rack 130 is flipped by the flip assembly 120, after the oil barrel is flipped to a horizontal state, when the residual oil in the oil barrel begins to be discharged from the oil outlet, the slide table 152 is driven to slide relative to the slide rail 151 by the sliding drive 153, so that the oil barrel placing rack 130 and the oil barrel are driven to slide by the movement of the slide table 152, so that after the oil barrel begins to discharge oil, the oil can be guided into the oil collecting box 110. It should be noted that the structure of the sliding assembly 150 is only one of the structures for achieving the above purpose. In other embodiments of the present invention, structures such as linear motor modules can also be used.

[0060] When the flip assembly 120 is configured, its function is to drive the oil barrel placement rack 130 to flip, thereby adjusting the position of the oil barrel. Specifically, the flip assembly 120 includes a flip frame 121, a flip shaft 122, a flip member 123 and a flip driving member 124; the flip frame 121 is connected to the slide 152, the flip member 123 is rotatably connected to the flip frame 121 through the flip shaft 122, and the flip driving member 124 is used to drive the flip member 123 to rotate relative to the flip frame 121; wherein, the oil barrel placement rack 130 is connected to the flip member 123. Through such a structural setting, the flip driving member 124 can drive the flip member 123 to rotate relative to the flip frame 121, thereby driving the oil barrel to flip. It should be noted that the structure of the above-mentioned flip assembly 120 is only one of the structures for achieving the above-mentioned purpose. In other embodiments of the present invention, structures such as a winch and a rotating gear can also be used.

[0061] When configuring the oil barrel rack 130, in order to improve the stability of the oil barrel in the oil barrel rack 130 during the turning process, the oil barrel rack 130 includes a main frame 131, a placement table 132 and a top stopper 133;

[0062] The main frame 131 is connected to the flip member 123 , and the placement platform 132 and the top stopper 133 are connected to the main frame 131 at intervals and are respectively supported at two ends of the oil barrel along the axis direction of the oil barrel.

[0063] Among them, the placement platform 132 and the top limit member 133 are connected to the main frame body 131 at intervals, and are respectively supported at both ends of the oil barrel along the axial direction of the oil barrel. The purpose of such a setting is to prevent the oil barrel from slipping along the axial direction of the oil barrel relative to the oil barrel placement rack 130 during the flipping process, thereby improving its stability; and in order to prevent the oil barrel from detaching from the oil barrel placement rack 130 during the flipping process, the oil barrel placement rack 130 also includes a pressing member 134, which presses on the outer periphery of the oil barrel to limit the movement of the oil barrel relative to the placement platform 132.

[0064] It should be noted that the above-mentioned placement platform 132, top stopper 133 and holding member 134 will not affect the rotation of the oil barrel driven by the rotating assembly 140; that is, the flip assembly 120 can drive the oil barrel to flip relative to the oil barrel placement rack 130 when the oil barrel is in a flipping or oil discharge state, and the placement platform 132, top stopper 133 and holding member 134 will not interfere with its rotation. Based on this, when configuring the holding member 134, its role is to ensure that the oil barrel on the oil barrel placement rack 130 has a degree of rotational freedom and prevent it from detaching from the oil barrel placement rack 130. Therefore, it can be set as a clamping ring, a clamp or a limiting ring sleeved on the outer periphery of the oil barrel, which is in smooth contact with the outer periphery of the oil barrel, or a roller is set on the contact with the outer periphery of the oil barrel, so as to reduce its friction and further reduce the restriction on the rotation of the oil barrel.

[0065] For further information, please refer to Figure 1-Figure 5 In this embodiment, when the flip assembly 120 is set, the rotating assembly 140 includes a rotating disk 141 and a rotating motor 142. The rotating disk 141 is rotatably set on the placement table 132 or the top limit member 133, and the rotating disk 141 is used to drive the oil barrel to rotate around its axis under the driving action of the rotating motor 142.

[0066] The present embodiment adopts a method of configuring a rotating disk 141 on both the placement table 132 and the top limit member 133. The purpose is to ensure that after the oil drum is placed on the oil drum placement rack 130, its two ends are relatively abutted against the two rotating disks 141, so that it can have rotational freedom, and the rotating motor 142 can drive one or both of the two rotating disks 141 to rotate.

[0067] It should be noted that, from the above content, it can be seen that in the present embodiment, the rotating disk 141 located on the placement table 132 and the top limit member 133 is respectively abutted against the two ends of the oil barrel. Therefore, on the basis of the rotating disk 141 on the placement table 132 being used to abut and carry the oil barrel, the top limit member 133 and its rotating disk 141 can be configured as a movable structure, that is, it can adjust its position relative to the main frame 131, so that the oil barrel can be loaded and unloaded conveniently, that is, when the oil barrel is assembled or removed, the top limit member 133 can be moved to a position abutting against the oil barrel, and after the oil barrel is assembled, it can be moved to a position abutting against the oil barrel.

[0068] For further information, please refer to Figure 1-Figure 5 In this embodiment, in order to improve the collection efficiency of residual oil, the oil barrel to be recovered for residual oil can be weighed during use to determine the amount of residual oil in the oil barrel. For oil barrels with a large amount of residual oil, oil can be pumped through the oil extraction pipe, and when the amount of residual oil is reduced, the residual oil can be collected by the above-mentioned flipping method. Based on this, the oil barrel residual oil collection device 100 also includes a weighing device 160 arranged on the rotating disk 141 or the placement table 132, which is used to weigh the oil barrel on the placement table 132 to determine the amount of residual oil in the oil barrel. It should be noted that during use, after the oil barrel is placed on the placement table 132, its initial weight needs to be weighed, and then compared with the weight of the empty barrel to determine whether the oil barrel adopts flipping residual oil recovery; or first adopts through the oil extraction pipe 172, and then performs flipping residual oil recovery; after the flipping residual oil recovery action is completed, the oil barrel needs to be weighed again to compare with its initial weight to determine the amount of residual oil recovery.

[0069] Based on the above content, it can be known that when configuring the oil drum placement rack 130, it is necessary to achieve its fixation and also to make the oil drum rotatable. Based on this, the rotating disk 141 can be rotatably set on the placement table 132 and the top limit member 133 through bearings, and the weighing device 160 can be set on the rotating disk 141 connected to the placement table 132.

[0070] The above are only specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by a technician familiar with the technical field within the technical scope disclosed by the present invention should be covered within the protection scope of the present invention.
