Description

Technical Field

[0001] This utility model relates to the technical field of lubricating oil preparation equipment, and more specifically, to a lubricating oil additive mixing device. Background Technology

[0002] In the preparation of lubricating oil, various liquid additives are usually added to the base oil, and the mixture is stirred to form a stable product. Existing lubricating oil mixing equipment generally consists of a mixing tank, a feed inlet, and a stirring mechanism.

[0003] Existing lubricating oil mixing devices typically add base oil to the mixing tank through an inlet located at the top of the tank. Operators usually add the base oil manually or via a pump. However, in practice, it is difficult to accurately measure the amount of base oil added, whether manually or using a pump, leading to the easy occurrence of over-addition. Excessive base oil not only affects the physicochemical properties of the finished lubricating oil but can also cause liquid spillage, resulting in material waste and environmental pollution. Furthermore, excessive base oil can alter the volume and viscosity distribution of the liquid within the mixing tank, increasing mixing resistance, reducing mixing uniformity and efficiency, and even causing excessive mixing load and increased energy consumption. Summary of the Invention

[0004] The purpose of this invention is to provide a lubricating oil additive mixing device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A lubricating oil additive mixing device includes a tank, a cover on the top of the tank, a stirring rod extending into the tank body on the cover, a motor on the cover for driving the stirring rod to rotate, a feed hopper on the cover communicating with the inside of the tank, a discharge pipe at the bottom of the tank, a circular hole at the edge of the cover, a hollow rod on the cover located at the circular hole, the interior of the hollow rod communicating with the circular hole, a telescopic rod inside the hollow rod extending into the tank body through the circular hole, a float at the bottom of the telescopic rod, graduations on the outer wall of the hollow rod, and multiple sets of detachable stirring blades on the stirring rod.

[0006] Furthermore, an indicator ring is fitted on the outer wall of the hollow rod, a lower crossbar is provided on the outer wall of the indicator ring, an upper crossbar is provided on the outer wall of the telescopic rod near the upper end, a connecting rod is provided between the upper crossbar and the lower crossbar, and a pull block is provided at the top of the telescopic rod.

[0007] Furthermore, an extension rod is provided on the outer wall near the upper end of the hollow rod, and a connecting block is provided on the end of the extension rod away from the hollow rod. A plug rod is threaded onto the connecting block, and a column is provided on the outer wall of the indicator ring. A plug hole for the plug rod to be inserted is provided inside the column.

[0008] Furthermore, the outer wall of the stirring rod is symmetrically provided with connecting plates, and multiple adjustment holes are evenly spaced on the connecting plates. Multiple sets of retaining rings are symmetrically provided on the stirring rod, and fixing plates are provided on both sides of the retaining rings. The fixing plates are provided with holes that match the adjustment holes, and bolts are inserted into the holes.

[0009] Furthermore, the bottom of the feed hopper is provided with a bent pipe, the bottom end of which faces the inner wall of the tank, and the bottom end of the bent pipe is provided with a flared opening that communicates with the bent pipe.

[0010] Furthermore, the float is equipped with a mounting post, and the mounting post has a threaded hole, with the lower end of the telescopic rod threadedly connected to the threaded hole.

[0011] Furthermore, multiple support legs are provided on the outer wall of the tank near the bottom.

[0012] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model uses a float ball that moves the telescopic rod and indicator ring along the scale as the liquid level rises, allowing operators to intuitively read the liquid level in the tank. This avoids excessive addition of base oil due to manual estimation or the inability of the delivery pump to measure, thus ensuring the accuracy of the mixing ratio.

[0013] This invention achieves flexible adjustment of the stirring blades in the height direction by setting multiple sets of retaining rings on the outer wall of the stirring rod and fixing them with bolts and nuts. The distribution position and number of stirring blades can be freely adjusted according to the volume, viscosity and mixing requirements of different batches of lubricating oil.

[0014] This invention features a pull block at the top of the telescopic rod, which allows the float to be lifted off the liquid surface once the liquid level stabilizes. The telescopic rod is then limited by inserting a rod into the insertion hole, thus preventing the float from repeatedly shaking due to liquid fluctuations during stirring, reducing component wear, and extending the service life of the device.

Detailed Implementation

[0021] To further understand the content of this utility model, a detailed description of this utility model will be provided in conjunction with the accompanying drawings and embodiments. It should be understood that the embodiments are merely illustrative of this utility model and are not intended to limit it.

[0022] The following is in conjunction with the appendix Figures 1-5 This embodiment will be described in further detail.

[0023] Please see Figures 1-5 This embodiment of a lubricating oil additive mixing device includes a tank 100, with a cover 101 detachably connected to the top of the tank 100. The cover 101 is provided with a stirring rod 102 extending into the tank 100. The stirring rod 102 is rotatably connected to the cover 101 via a bearing. The upper end of the stirring rod 102 passes through the cover 101 and is connected to the output end of a motor 103 fixedly installed on the cover 101. The motor 103 can drive the stirring rod 102 to rotate, thereby driving the liquid in the tank 100 to be fully mixed.

[0024] In this embodiment, connecting plates 300 are symmetrically welded to both sides of the outer wall of the stirring rod 102. The connecting plates 300 are arranged along the axial direction of the stirring rod 102, and multiple adjusting holes 301 are evenly spaced on the connecting plates 300. Multiple sets of retaining rings 302 are symmetrically arranged on the stirring rod 102. Fixing plates 303 are welded to both sides of the retaining rings 302. The fixing plates 303 have holes 304 that are adapted to the corresponding adjusting holes 301. Bolts 305 that pass through the corresponding adjusting holes 301 are inserted into the holes 304. The ends of the bolts 305 are then tightened and fixed by nuts, so that the retaining rings 302 can be stably locked at the selected position of the adjusting hole 301. The stirring blades 109 are welded to the outer wall of the retaining rings 302. The stirring blades 109 are integrally installed on the stirring rod 102 along with the retaining rings 302, so that the stirring rod 102 rotates to drive the stirring blades 109 to stir. This structure allows operators to loosen the connection between the nut and bolt 305 and remove the bolt 305 during actual use, enabling the retaining ring 302 to slide freely up and down on the stirring rod 102. After selecting a suitable height, the bolt 305 and nut are then used to re-lock the rod, thus achieving flexible adjustment of the stirring blade 109 height. Since the stirring blade 109 and retaining ring 302 are welded together, the blade installation is secure. Furthermore, the retaining ring 302, as an independent component, can be disassembled as a whole, making the replacement and maintenance of the stirring blade 109 more convenient. The distribution and number of the stirring blades 109 can be freely adjusted according to the volume, viscosity, and mixing requirements of different batches of lubricating oil to improve the uniformity of mixing and enhance the mixing effect.

[0025] In this embodiment, when replacement or adjustment is required, the cover 101 on the top of the tank 100 can be lifted as a whole by a hoisting device. The cover 101 drives the stirring rod 102 to rise together. At this time, the stirring blade 109 extends out of the tank 100 along with the stirring rod 102, and the operator can adjust or replace the stirring blade 109.

[0026] The cover 101 is fixedly connected to a feed hopper 104 that communicates with the interior of the tank 100. Base oil or additives can be added into the tank 100 through the feed hopper 104. A bent pipe 110 is fixedly connected to the bottom of the feed hopper 104. The bottom port of the bent pipe 110 faces the inner wall of the tank 100. The bottom port of the bent pipe 110 has a flared mouth 111 that communicates with the bent pipe 110. This allows the base oil to fall smoothly along the inner wall of the tank 100 when it is added into the tank 100, avoiding direct impact of the liquid on the liquid surface and causing splashing or bubbles. This reduces the turbulence before oil mixing and makes subsequent mixing more stable and efficient.

[0027] Specifically, the bottom of the tank 100 is provided with a discharge pipe 105, and a valve is provided on the discharge pipe 105 for discharging lubricating oil after mixing is completed; in order to support the discharge pipe 105, multiple support legs 113 are provided on the outer wall of the tank 100 near the bottom for suspending the bottom of the tank 100 so as to install the discharge pipe 105.

[0028] Please see Figures 2-3 In this embodiment, a circular hole is provided at the edge of the cover 101, and a hollow rod 106 located at the circular hole is provided on the cover 101. The hollow rod 106 is fixedly connected to the cover 101, and the interior of the hollow rod 106 is connected to the circular hole. A telescopic rod 107 is provided inside the hollow rod 106, which passes through the circular hole and extends into the tank 100. A float 108 is fixedly provided at the bottom end of the telescopic rod 107. The float 108 can float upward as the liquid level in the tank 100 rises, causing the telescopic rod 107 to slide upward inside the hollow rod 106. The hollow rod 106 has evenly marked scale lines and numerical values ​​on its outer wall. An indicator ring 200 is fitted on the outer wall of the hollow rod 106. A lower crossbar 201 is fixedly connected to the outer wall of the indicator ring 200. An upper crossbar 202 is fixedly connected to the outer wall of the telescopic rod 107 near its upper end. A connecting rod 203 is fixedly connected between the upper crossbar 202 and the lower crossbar 201. When the telescopic rod 107 rises with the liquid level under the action of the float 108, the upper crossbar 202 drives the lower crossbar 201 through the connecting rod 203, thereby causing the indicator ring 200 to slide upward along the outer wall of the hollow rod 106. Thus, the operator can intuitively read the height of the liquid level in the tank 100 by observing the position of the indicator ring 200 at the scale line of the hollow rod 106, realizing real-time monitoring of the amount of base oil added and avoiding excessive addition of base oil.

[0029] In this embodiment, the float 108 is located at the edge of the tank 100 and is spaced a certain distance from the outer end of the stirring blade 109, so that the float 108 will not touch the stirring blade 109 when the liquid level rises and floats, thereby avoiding interference with the upward movement of the float 108.

[0030] Please see Figures 2-3 In this embodiment, a pull block 204 is fixedly connected to the top of the telescopic rod 107. When the height of the base oil level in the tank 100 reaches the expected value and remains stable, the operator can lift the telescopic rod 107 upward through the pull block 204 to make the float 108 leave the liquid surface, thereby avoiding the continuous shaking of the float 108 caused by the fluctuation of the liquid surface during the stirring process, which would lead to the wear of the telescopic rod 107 and its driving components.

[0031] To further stabilize the position of the float 108, an extension rod 205 is fixedly connected to the outer wall of the hollow rod 106. A connecting block 206 is fixedly connected to the end of the extension rod 205 away from the hollow rod 106. A threaded insertion rod 207 is threaded onto the connecting block 206. A column 208 is provided on the outer wall of the indicator ring 200, and an insertion hole 209 is provided inside the column 208. When the float 108 is lifted to a position above the liquid surface, the insertion rod 207 is rotated to insert it into the insertion hole 209, thereby limiting the extension rod 107 and keeping the float 108 suspended, preventing it from falling back and re-contacting the liquid surface, thus ensuring the durability of the components during stirring. If the insertion rod 207 and the insertion hole 209 are not aligned after the extension rod 107 is pulled up, the pull block 204 can be rotated to rotate the column 208, aligning the insertion hole 209 with the insertion rod 207, and then the insertion rod 207 can be rotated to insert it into the insertion hole 209.

[0032] Please see Figure 2 In this embodiment, a mounting post 112 is fixedly connected to the float 108. The mounting post 112 has a threaded hole. The lower end of the telescopic rod 107 is threaded into the threaded hole, so that the float 108 can be easily disassembled and replaced. Operators can select floats 108 with different buoyancy as needed to adapt to different liquid densities and working conditions.

[0033] In summary, the above description is only a preferred embodiment of the present utility model. All equivalent changes and modifications made within the scope of the patent application of the present utility model shall fall within the scope of the patent of the present utility model.
