Description

Technical Field

[0001] This utility model relates to the field of lubricating oil production technology, specifically to a lubricating oil mixing device. Background Technology

[0002] Lubricating oil is a liquid or semi-solid lubricant used between mechanical parts. Its main function is to reduce friction and wear, while also providing cooling, cleaning, and sealing functions. In the lubricating oil processing, the base oil and additives must first be mixed in a mixing tank. However, because both the base oil and additives have high viscosity and poor flowability, the mixing is uneven, resulting in a long mixing time and hindering efficient production. In related technologies, such as the lubricating oil mixing equipment described in patent CN215428695U, an outlet hole 8 is provided on the side wall of the primary mixing tank 7, and a primary stirring device is also provided in the cover 3, located inside the primary mixing tank 7. The lubricating oil mixing device 1 has a primary mixing tank 7 set on the cover 3. During mixing, the additives first enter the primary mixing tank 7 through the feeding hole 6. The primary mixing device in the primary mixing tank 7 pre-stirs the various additives. The pre-stirred additives flow into the tank 2 through the outlet hole 8. The base oil enters from the feed port 5 at the bottom of the tank 2 and mixes with the pre-stirred additives. This mixing method has a better mixing effect and can avoid uneven mixing of various additives and base oil, thus ensuring the properties of the lubricating oil.

[0003] In the aforementioned apparatus and technical solution, although the two-step mixing method can improve the uniformity of the additive and base oil mixing to some extent, the main mixing method still uses a conventional single-bar stirring mechanism. This results in relatively low mixing efficiency and slow material alternation between the upper and lower layers when mixing viscous lubricating oils. Furthermore, due to the poor fluidity of the lubricating oil and additives, natural leakage through the primary mixing tank and outlet further increases the mixing time with the base oil. Therefore, the processing mixing efficiency and practicality need further improvement. Utility Model Content

[0004] The purpose of this section is to outline some aspects of the embodiments of this utility model and to briefly introduce some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be used to limit the scope of this utility model.

[0005] Therefore, the purpose of this utility model is to provide a lubricating oil mixing device to solve the problem mentioned in the background art that the existing lubricating oil mixing devices still use conventional single-bar stirring in the main mixing method of additives and base oil, which results in low mixing efficiency and slow alternation of upper and lower layers of materials when stirring viscous lubricating oil; in addition, due to the poor fluidity of lubricating oil and additives, the natural leakage through the primary mixing tank and the outlet hole further increases the mixing time with the base oil.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a lubricating oil mixing device, comprising a mixing tank hopper, the top of the mixing tank hopper having an opening and a top cover covering the opening, parallel spiral push rods being rotatably installed on both sides of the lower end inside the mixing tank hopper, a rotary drive assembly for driving the spiral push rods on both sides to rotate synchronously at one end of the mixing tank hopper, and a primary mixing injection cylinder and an injection pipe pump connected to the primary mixing injection cylinder being arranged in the center of the upper end of the top cover;

[0007] The base oil and additives are pumped to the primary mixing injection cylinder by the injection pipe pump. After being rapidly mixed in the primary mixing injection cylinder, they are directly introduced into the inner cavity of the mixing tank hopper.

[0008] In a preferred embodiment of the lubricating oil mixing device described in this utility model, the spiral push rod is horizontally arranged inside the mixing tank hopper, and both ends of the spiral push rod are rotatably installed inside the mixing tank hopper via a sealing shaft. The bottom sides of the mixing tank hopper also have arc-shaped grooves corresponding to the spiral push rod.

[0009] As a preferred embodiment of the lubricating oil mixing device described in this utility model, the rotary drive assembly includes passive gears coaxially fixed to the ends of the spiral push rods on both sides, a drive gear meshing with the passive gears on both sides, a first motor for driving the drive gear to rotate axially, and a protective cover fixed to the outside of the mixing tank hopper and fixedly installed with the first motor.

[0010] As a preferred embodiment of the lubricating oil mixing device of this utility model, the primary mixing and feeding cylinder includes a conveying cylinder vertically fixed to the top of the top cover, a discharge port located at the bottom of the conveying cylinder and connected to the inner cavity of the mixing tank, a rotating shaft vertically and movably installed on the inner side of the conveying cylinder, multiple stirring blades fixed on the outer periphery of the rotating shaft, and a second motor disposed at the upper end of the conveying cylinder for driving the rotating shaft to rotate axially.

[0011] As a preferred embodiment of the lubricating oil mixing device described in this utility model, the injection pump includes a main pipe with one end connected to the upper part of the inner cavity of the conveying cylinder and the other end being a sealing structure, an oil pump disposed on the main pipe at the connection point with the conveying cylinder, and a lubricating oil delivery pipe joint and an additive delivery pipe joint respectively connected to the main pipe.

[0012] Electromagnetic flow valves are also installed on the lubricating oil delivery pipe joint and the additive delivery pipe joint, respectively.

[0013] As a preferred embodiment of the lubricating oil mixing device described in this utility model, the bottom of the mixing tank has a discharge port and a discharge gate corresponding to the discharge port.

[0014] In a preferred embodiment of the lubricating oil mixing device described in this utility model, multiple support legs are fixed on both sides of the mixing tank, and a connecting base plate is fixed between the bottoms of adjacent support legs.

[0015] In a preferred embodiment of the lubricating oil mixing device described in this utility model, a drain valve is also connected to the bottom of one end of the mixing tank.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows: During mixing, the base oil and additives are quantitatively pumped into the conveying cylinder by a pump. Driven by a second motor, multiple longitudinally arranged stirring blades rotate, rapidly mixing the base oil and additives within the cylinder. After initial mixing, the oil quickly falls into the central area of ​​the mixing tank wall under gravity and pressure, significantly reducing natural leakage and increasing the mixing time with the base oil. Simultaneously, the rotary drive assembly drives the two spiral push rods on both sides to rotate relative to each other, causing the falling oil to spread out quickly. During this process, the spiral push rods on both sides horizontally push, rub, and mix the oil in the tank, while the radially rotating oil on both sides is forcibly mixed and agitated. This combined effect effectively improves the mixing effect and progress between the base oil and additives, significantly enhancing processing efficiency and practicality compared to the prior art.

[0024] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0025] Secondly, this utility model is described in detail with reference to the schematic diagrams. When describing the embodiments of this utility model, for ease of explanation, the cross-sectional views showing the device structure may be partially enlarged, not according to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of this utility model. In addition, in actual manufacturing, the three-dimensional spatial dimensions of length, width, and depth should be included.

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0027] Figures 1-6 The diagram shown is a complete structural schematic of a lubricating oil mixing device according to this utility model. Please refer to [link / reference]. Figures 1-6This embodiment of a lubricating oil mixing device includes a mixing tank 100, the top of which has an open opening and a top cover 120 covering the opening. Parallel spiral push rods 200 are rotatably mounted on both sides of the lower end inside the mixing tank 100. One end of the mixing tank 100 has a rotary drive assembly 300 for driving the spiral push rods 200 on both sides to rotate synchronously. A primary mixing injection cylinder 400 and an injection pipe pump 500 connected to the primary mixing injection cylinder 400 are arranged in the center of the upper end of the top cover 120. Base oil and additives are pumped to the primary mixing injection cylinder 400 through the injection pipe pump 500, and after being rapidly mixed by the primary mixing injection cylinder 400, they are directly introduced into the inner cavity of the mixing tank 100.

[0028] The spiral pusher rod 200 is horizontally arranged inside the mixing hopper 100. Both ends of the spiral pusher rod 200 are rotatably mounted inside the mixing hopper 100 via sealing shafts. The bottom sides of the mixing hopper 100 also have arc-shaped grooves corresponding to the spiral pusher rod 200. It should be noted that... Figure 2 and attached Figure 6It can be seen that the upward or downward rotation of the two spiral push rods 200 is intended to physically squeeze the oil from both sides towards the center, thereby accelerating the fusion process. It is also important to note that the blades of the two spiral push rods 200 push in opposite directions to prevent lubricating oil from piling up at one end of the mixing tank. The rotary drive assembly 300 includes driven gears 310 coaxially fixed to the ends of the two spiral push rods 200, driving gears 320 meshing with the driven gears 310, a first motor 330 for driving the driving gears 320 axially, and a protective cover 340 fixed to the outside of the mixing tank 100 and fixedly installed with the first motor 330. In other embodiments, independent drive or other rotary drive methods may also be used, and this is not limited. The primary mixing and feeding cylinder 400 includes a feeding cylinder 410 vertically fixed to the top of the top cover 120, a discharge port 4101 located at the bottom of the feeding cylinder 410 and connected to the inner cavity of the mixing tank 100, a rotating shaft 420 vertically and movably installed inside the feeding cylinder 410, multiple stirring blades 430 fixed to the outer periphery of the rotating shaft 420, and a second motor 440 disposed at the upper end of the feeding cylinder 410 for driving the rotating shaft 420 to rotate axially. The feeding pipe pump 500 includes a main pipe 510 with one end connected to the upper part of the inner cavity of the feeding cylinder 410 and the other end being a sealing structure, an oil pump 520 disposed on the main pipe 510 at the connection point with the feeding cylinder 410, and a lubricating oil delivery pipe joint 530 and an additive delivery pipe joint 540 respectively connected to the main pipe 510; wherein, the lubricating oil delivery pipe joint 530 and the additive delivery pipe joint 540 are also respectively provided with electromagnetic flow valves. It is understood that the electromagnetic flow valve can control and detect the flow of base oil and additives input into the main pipe 510 through the lubricating oil delivery pipe joint 510 and the additive delivery pipe joint 540, thereby forming a stable unit delivery volume in conjunction with the oil pump 520 and the control system. In addition, the lubricating oil delivery pipe joint 530 and the additive delivery pipe joint 540 are respectively connected to the corresponding base oil pool and additive pool through external pipelines. Specifically, during mixing, the base oil and additives are quantitatively pumped into the conveying cylinder 410 by the injection pump 500. Driven by the second motor 440, multiple longitudinally arranged stirring blades 430 rotate and rapidly stir and mix the base oil and additives in the cylinder. After initial fusion, the oil falls rapidly into the central area of ​​the inner wall of the mixing tank 100 under the action of gravity and pressure, greatly reducing natural leakage and increasing the mixing time with the base oil. At the same time, the rotary drive assembly 300 drives the two spiral push rods 200 on both sides to rotate relative to each other, causing the falling oil to spread out quickly. During this process, the two spiral push rods 200 on both sides will horizontally push, rub and fuse the oil in the tank, while the oil on both sides will be forcibly fused and crushed by the radially rotating oil.

[0029] Furthermore, the bottom of the mixing tank 100 has a discharge port 1001 and a discharge gate 110 corresponding to the discharge port 1001. It can be understood that the discharge gate 110 in this embodiment can be manual or automatic, with automatic gates, such as electric, pneumatic or hydraulic gates, being preferred here; in actual applications, a guide channel corresponding to the collection unit should also be connected to the bottom of the mixing tank 100, which can be determined according to the actual situation.

[0030] Furthermore, multiple support legs 600 are fixed on both sides of the mixing tank 100, and a connecting base plate 610 is fixed between the bottoms of adjacent support legs 600. The support legs 600 and the connecting base plate 610 can be used to stably support and stabilize the mixing tank 100.

[0031] Furthermore, a drain valve 130 is connected to the bottom of one end of the mixing tank 100. When the mixing tank 100 needs to be cleaned, the top cover 120 can be opened and cleaning agent and cleaning liquid can be introduced into the tank. After cleaning, the drain valve 130 can be opened to discharge the sewage. In addition, the top cover 120 and the mixing tank 100 can be vertically overlapped, hinged, etc.

[0032] In summary, the lubricating oil mixing device of this embodiment, during mixing, uses a delivery pump 500 to quantitatively pump base oil and additives into a delivery cylinder 410. Driven by a second motor 440, multiple longitudinally arranged stirring blades 430 rotate, rapidly stirring and mixing the base oil and additives in the cylinder. After initial fusion, the oil quickly falls into the central area of ​​the inner wall of the mixing tank 100 under the action of gravity and pressure, greatly reducing natural leakage and increasing the mixing time with the base oil. At the same time, the rotary drive assembly 300 drives the two spiral push rods 200 on both sides to rotate relative to each other, causing the falling oil to spread out quickly. During this process, the two spiral push rods 200 on both sides horizontally push, rub, and fuse the oil in the tank, while the oil on both sides is forcibly fused and agitated by the radial rotation. With the cooperation of both, the mixing effect and progress between the base oil and additives are effectively improved, and the processing efficiency and practicality are significantly improved compared with the prior art.

[0033] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
