Description

Technical Field

[0001] The utility model relates to the technical field of lubricating grease proportioning, in particular to a lubricating grease preparation device capable of automatically proportioning. Background Art

[0002] Lubricating oil and grease, in general, are a type of "lubricant." Simply put, a lubricant is something that exists between two objects in relative motion and reduces the friction caused by contact.

[0003] In the prior art, when using, the proportioning preparation device of lubricating grease is mostly connected to the raw material storage tank and the mixing tank, and quantitative supply is carried out by means of a metering pump or a solenoid valve. However, in actual use, the lubricating grease remaining stationary in the raw material storage tank may slowly settle when it remains stationary for a long time, and the heavier particles or substances in the lubricating grease may cause uneven distribution of the grease components, and the concentration of the grease components in different parts of the raw material tank may be inconsistent. For example, the concentration of the thickener or additive in a certain part of the grease is too high or too low, which will cause inaccurate proportions in subsequent proportions and affect the quality of the final product. Therefore, it is necessary to propose a lubricating grease preparation device that can automatically proportion to address the above problems. Utility Model Content

The multiple groups of raw material tanks are fixedly spaced apart and are connected to the interior of the mixing tank through connecting pipes. Solenoid valves are installed in the connecting pipes. Feed pipes are fixedly connected to the outer walls of the multiple groups of raw material tanks and are connected to the interior of the raw material tanks. A device barrel is fixedly connected to the raw material tank, a flow groove is opened in the device barrel, and a spiral blade is rotatably connected to the device barrel.

[0007] Preferably, a discharge pipe is fixedly connected to the outer wall of the mixing tank and is communicated with the interior of the mixing tank. The two groups of flow grooves are respectively located at the upper and lower ends of the device barrel and are both opened through.

[0008] Preferably, the bottom of the mixing tank is rotatably connected to a rotating rod, and the outer wall of the rotating rod is equipped with multiple groups of stirring rods.

[0009] Preferably, the plurality of stirring rods are annular and distributed on the outer wall of the rotating rod at equal intervals. The upper end of the frame is fixedly connected to a side plate, and the outer wall of the side plate is L-shaped.

[0010] Preferably, the upper end surface of the frame is rotatably connected to a plurality of sprockets, and the plurality of sprockets are coaxially fixedly connected to the spiral blades and the rotating rod respectively.

[0011] Preferably, a servo motor is fixedly connected to the upper end surface of the side plate, and the end of the output shaft of the servo motor is coaxially fixedly connected to the adjacent sprocket.

[0012] Preferably, the multiple groups of sprockets are interconnected by chains, and sealing plugs are installed at the pipe openings of the multiple groups of feed pipes.

[0013] The utility model has the following beneficial effects:

[0014] 1. The utility model can transport heavier substances such as thickeners or additives precipitated at the bottom of the raw material tank to the flow groove on the top of the tank through the coordinated design of the spiral blades and the device barrel, thereby preventing the problem of precipitation accumulation caused by the raw materials standing still in the tank for a long time, ensuring that all kinds of raw materials are evenly distributed before proportioning, thereby solving the problems of inaccurate proportioning and uneven material composition caused by precipitation.

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0023] Reference Figure 1-5 , a lubricating grease preparation device that can automatically proportion, includes a frame 1, on which are installed multiple groups of raw material tanks 2 and a single group mixing tank 3, the multiple groups of raw material tanks 2 are fixed in distance, and are all connected to the interior of the mixing tank 3 through connecting pipes, and solenoid valves are installed in the connecting pipes, the outer walls of the multiple groups of raw material tanks 2 are fixedly connected with feeding pipes 4, and are all connected to the interior of the raw material tank 2, and the raw material tank 2 is fixedly connected with a device barrel 10, the device barrel 10 is provided with a flow groove 14, a spiral blade 11 is rotatably connected to the device barrel 10, and a discharge pipe 9 is fixedly connected to the outer wall of the mixing tank 3 and is connected to the interior of the mixing tank 3, the two groups of flow grooves 14 are respectively located at the upper and lower ends of the device barrel 10, and are both opened through; the spiral blade 11 is combined with the device barrel 10, and the material precipitated at the bottom of the raw material tank 2 can be transported to the flow groove 14 at the top of the raw material tank 2, so as to prevent the material from being deposited at the bottom of the tank for a long time, thereby helping to maintain a uniform distribution of the material in the tank and avoid the problem of uneven material composition due to local deposition.

[0024] A rotating rod 12 is rotatably connected to the bottom of the mixing tank 3, and multiple groups of stirring rods 13 are installed on the outer wall of the rotating rod 12. The multiple groups of stirring rods 13 are all annular and evenly spaced on the outer wall of the rotating rod 12. The upper end of the frame 1 is fixedly connected to a side plate 7, and the outer wall of the side plate 7 is L-shaped; the rotation of the multiple groups of stirring rods 13 can evenly mix different raw materials, avoid stratification and uneven proportioning problems, and improve the uniformity and stability of oil preparation.

[0025] The upper end surface of the frame 1 is rotatably connected to multiple sets of sprockets 5, and the multiple sets of sprockets 5 are coaxially fixedly connected to the spiral blades 11 and the rotating rod 12 respectively. The upper end surface of the side plate 7 is fixedly connected to a servo motor 8, and the end of the output shaft of the servo motor 8 is coaxially fixedly connected to the adjacent sprocket 5. The multiple sets of sprockets 5 are interconnected by chains 6, and sealing plugs are installed at the pipe openings of the multiple sets of feed pipes 4. The design of the sprocket 5 group can drive the multiple sets of spiral blades 11 and the stirring rod 13 to rotate through a single set of output mechanisms.

[0026] In the present invention, when the device is used specifically: different types of lubricating grease raw materials such as base oil, thickener, additives, etc. are stored in multiple groups of raw material tanks 2. Before the equipment is operated, the servo motor 8 drives the spiral blade 11 in the device through the sprocket 5, and the chain 6 is arranged to synchronously drive the multiple groups of sprockets 5 and the spiral blade 11 to rotate. The spiral blade 11 cooperates with the device barrel 10 to transport the heavier substances such as thickeners or additives precipitated at the bottom of the raw material tank 2 to the flow groove 14 at the top, preventing the problem of precipitation accumulation caused by long-term stillness of the raw materials, ensuring uniform distribution of materials in the tank, and maintaining the consistency of each component.

[0027] Then, the solenoid valve in the connecting pipe controls the raw materials in each raw material tank 2 to be accurately transported to the mixing tank 3 through the connecting pipe according to the set formula ratio. Due to the action of the spiral blade 11, all kinds of raw materials in the raw material tank 2 are kept evenly distributed, avoiding the situation of excessive or insufficient local components during the raw material transportation process.

[0028] During the process of conveying the raw materials to the mixing tank 3, the rotating rod 12 and the stirring rod 13 in the mixing tank 3 rotate synchronously, and the raw materials from different sources are fully mixed through stirring, further avoiding the separation or unevenness of the components, and ensuring the uniformity and consistency of the finished lubricating grease.

[0029] After the mixing is completed, the lubricating grease in the mixing tank 3 flows out through the discharge pipe 9 and enters the next process link.

[0030] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
