Description

Technical Field

[0001] This utility model relates to the technical field of grease production equipment, and in particular to a stirring device for grease production. Background Technology

[0002] Grease is a thick, oily, semi-solid substance used in the friction parts of machinery for lubrication and sealing. It is also used on metal surfaces to fill gaps and prevent rust. Grease is mainly composed of three parts: thickener, base oil, and additives. The working principle of grease is that the thickener keeps the oil in the position that needs lubrication. When there is a load, the thickener releases the oil, thereby achieving the lubrication effect. The quality of grease depends on the mixing and blending of the components. Therefore, mixing equipment is an essential piece of equipment in the grease production process.

[0003] The characteristic of grease is that it has a certain viscosity. This characteristic also leads to some problems with existing grease mixing equipment. The main problems are as follows: First, grease tends to stick to the mixing container, making cleaning inconvenient. Second, after the grease is mixed, the discharge is slow, resulting in low production efficiency. Utility Model Content

[0004] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a stirring device for grease production, which facilitates the cleaning of residual grease and has high discharge efficiency.

[0005] A stirring device for producing lubricating grease according to an embodiment of the present invention includes:

[0006] A mixing tank, wherein the top of the mixing tank is open and the bottom is provided with a discharge pipe;

[0007] A lifting unit is provided on the upper side of the mixing tank in a lifting manner;

[0008] A rotating part is rotatably disposed on the lifting part about a first axis, wherein the first axis is vertically distributed.

[0009] A stirring section is rotatably disposed on the rotating section about a second axis, the second axis being vertically distributed;

[0010] An extrusion section is disposed on the rotating section;

[0011] The lifting unit has at least a first position during the lifting process. When the lifting unit is in the first position, the rotating unit can rotate so that either the stirring unit or the extrusion unit is directly above the mixing tank. When the stirring unit is directly above the mixing tank, the lifting unit can move downward to allow the stirring unit to extend into the mixing tank. When the extrusion unit is directly above the mixing tank, the lifting unit can move downward to allow the extrusion unit to extend into the mixing tank and extrude the material in the mixing tank downward.

[0012] The mixing equipment for producing lubricating grease according to the embodiments of the present invention has at least the following beneficial effects:

[0013] In operation, first raise the lifting unit to the first position, then add the thickener, base oil, additives, and other raw materials for producing lubricating grease into the mixing tank. Next, rotate the rotating unit to position the mixing unit directly above the mixing tank. Then, lower the lifting unit to allow the mixing unit to extend into the mixing tank. Stop lowering the lifting unit at the target position, and then rotate the mixing unit to agitate the materials inside the tank. After agitation, raise the lifting unit to the first position, open the discharge pipe, and then rotate the rotating unit to position the extrusion unit directly above the mixing tank. Lower the lifting unit to allow the extrusion unit to extend into the mixing tank and extrude downwards, squeezing the materials inside to discharge them quickly and efficiently from the discharge pipe. Stop lowering the lifting unit at the target position. After discharge, raise the lifting unit back to the first position. When cleaning the mixing tank, position the lifting unit to the first position and rotate the rotating unit to ensure that both the extrusion unit and the mixing unit are away from the top of the mixing tank. The operator can then clean the inside of the mixing tank through the top opening, making operation very convenient. The above-mentioned structure allows for fast and efficient material discharge, and also facilitates the cleaning of residual grease inside the mixing tank.

[0025] According to some embodiments of the present invention, the extrusion plate is provided with a plurality of sliding rods, the sliding rods being vertically slidably inserted through the rotating part, and a limiting structure being detachably connected to the sliding rods. The limiting structure is used to abut against the rotating part to limit the downward displacement of the sliding rods relative to the rotating part.

[0026] According to some embodiments of the present invention, the elastic part is configured as a compression spring and sleeved on the slide rod, with the upper and lower ends of the compression spring respectively abutting the rotating part and the pressing plate.

The use of "first" and "second" is for distinguishing technical features only and should not be construed as indicating or implying relative importance, or implicitly indicating the number of technical features or their sequential relationship.

[0049] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0050] The characteristic of grease is that it has a certain viscosity. This characteristic also leads to some problems with existing grease mixing equipment. The main problems are as follows: First, grease tends to stick to the mixing container, making cleaning inconvenient. Second, after the grease is mixed, the discharge is slow, resulting in low production efficiency.

[0051] Therefore, this utility model proposes a stirring device for producing lubricating grease, which can effectively improve the above-mentioned problems.

[0052] The mixing equipment for producing lubricating grease according to an embodiment of the present invention is described below with reference to the accompanying drawings.

[0053] Reference Figures 1 to 4 As shown, a mixing device for producing lubricating grease according to an embodiment of the present invention includes: a mixing tank 100, a lifting part 200, a rotating part 300, a mixing part 400, and an extrusion part 500.

[0054] The mixing tank 100 has an opening at the top and a discharge pipe 110 at the bottom. It is conceivable that materials can be added from the top opening of the mixing tank 100 and discharged from the discharge pipe 110. A container can be set on the lower side of the discharge pipe 110 to receive the discharged materials. Obviously, a valve is set on the discharge pipe 110 to control the opening and closing of the discharge pipe 110.

[0055] The lifting unit 200 is vertically mounted on the upper side of the mixing tank 100.

[0056] The rotating part 300 is rotatably disposed on the lifting part 200 about a first axis, which is vertically distributed, meaning that the rotating part 300 can rotate relative to the lifting part 200 about the first axis.

[0057] The stirring part 400 is rotatably disposed on the rotating part 300 about the second axis, which is vertically distributed, meaning that the stirring part 400 can rotate about the second axis relative to the rotating part 300. It should be noted that the first axis and the second axis are staggered in the horizontal direction.

[0058] The extrusion section 500 is disposed on the rotation section 300, and the extrusion section 500 and the stirring section 400 are respectively located on opposite sides of the first axis.

[0059] The lifting part 200 has at least a first position during the lifting process. When the lifting part 200 is in the first position, the rotating part 300 can rotate so that either the stirring part 400 or the extrusion part 500 is directly above the mixing tank 100. When the stirring part 400 is directly above the mixing tank 100, the lifting part 200 can move downward so that the stirring part 400 extends into the mixing tank 100. After the stirring part 400 extends into the mixing tank 100, the stirring part 400 can rotate relative to the rotating part 300 around the second axis to stir the material in the mixing tank 100. When the extrusion part 500 is directly above the mixing tank 100, the lifting part 200 can move downward so that the extrusion part 500 extends into the mixing tank 100 and extrudes the material in the mixing tank 100 downward, so that the material (grease) can be discharged from the discharge pipe 110 by the extrusion force during discharge.

[0060] It is understandable that the lifting unit 200 has a second position and a third position during the lifting process. The height of the second position and the third position is lower than the height of the first position. When the stirring unit 400 is directly above the stirring tank 100, the lifting unit 200 can move downward from the first position to the second position (e.g., Figure 2 As shown), so that the stirring part 400 extends into the mixing tank 100 until the bottom end of the stirring part 400 is slightly higher than the inner bottom wall of the mixing tank 100; when the extrusion part 500 is directly above the mixing tank 100, the lifting part 200 can move downward from the first position to the third position (as shown). Figure 3As shown), the extrusion section 500 extends into the mixing tank 100 and extrudes the material inside the mixing tank 100 from top to bottom until the bottom end of the extrusion section 500 contacts the inner bottom wall of the mixing tank 100; obviously, the second position and the third position can be at the same height or at different heights. For ease of control, the second position and the third position can be at the same height.

[0061] Furthermore, it is obvious that when the lifting part 200 is in the first position, during the rotation of the rotating part 300, the stirring part 400 and the extrusion part 500 can both avoid being directly above the mixing tank 100.

[0062] In this embodiment of the grease production mixing equipment, during use, the lifting unit 200 is first raised to the first position, and then thickeners, base oils, additives, and other raw materials for producing grease are added to the mixing tank 100. Then, the rotating unit 300 is rotated so that the mixing unit 400 is directly above the mixing tank 100. Next, the lifting unit 200 is lowered so that the mixing unit 400 extends into the mixing tank 100. When it reaches the target position (second position), the lifting unit 200 stops descending. Then, the mixing unit 400 is rotated to mix the materials in the mixing tank 100. After mixing is complete, the lifting unit 200 is raised to the first position, the discharge pipe 110 is opened, and then the rotating unit 300 is rotated so that the extrusion unit 500 is positioned... The lifting unit 200 is positioned directly above the mixing tank 100. The lifting unit 200 is then lowered to allow the extrusion unit 500 to extend into the mixing tank 100 and extrude downwards, squeezing the material inside. This allows the material to be discharged quickly and efficiently from the discharge pipe 110. The lifting unit 200 stops descending at the target position (third position). After discharge, the lifting unit 200 is raised back to the first position. When cleaning the mixing tank 100 is required, the lifting unit 200 is positioned in the first position, and the rotating unit 300 is rotated so that the extrusion unit 500 and the mixing unit 400 avoid the upper side of the mixing tank 100. At this point, the operator can clean the interior of the mixing tank 100 through the top opening, making operation very convenient. This grease production mixing equipment with the above-described structure can discharge material quickly and efficiently, and also facilitates the cleaning of residual grease inside the mixing tank 100.

[0063] It should be noted that both the lifting part 200 and the rotating part 300 are frame structures, and their shapes can take many forms. This embodiment does not limit their specific shapes.

[0064] It is understood that, in some embodiments of this utility model, reference is made to... Figures 1 to 4 As shown, the mixing equipment for producing grease also includes a frame 800, a mixing tank 100, and a lifting unit 200, all of which are mounted on the frame 800.

[0065] The frame 800 is equipped with a first drive unit 810. A lifting unit 200 is connected to the output end of the first drive unit 810 and can be raised and lowered under the drive of the first drive unit 810. The first drive unit 810 can be a hydraulic rod or a cylinder. A guide sleeve 820 is provided on the cylinder body of the hydraulic cylinder or the cylinder. The lifting unit 200 is equipped with a vertically extending guide rod 210, which slides vertically through the guide sleeve 820 to provide vertical sliding guidance. A second drive unit 220 is provided on the lifting unit 200. A rotating unit 300 is connected to the output end of the second drive unit 220 and can rotate relative to the lifting unit 200 around a first axis under the drive of the second drive unit 220. The second drive unit 220 can be a combination structure of a motor, a synchronous belt and a synchronous pulley, or a combination structure of a motor, a belt and a pulley. A third drive unit 320 is provided on the rotating part 300. The stirring part 400 is connected to the output end of the third drive unit 320 and can rotate relative to the rotating part 300 around the second axis under the drive of the third drive unit 320. The third drive unit 320 can be a motor. The above drive structure is a conventional technical means, so it will not be described in detail here.

[0066] Reference Figure 1 , Figure 2 and Figure 4 As shown, in some embodiments of this utility model, the stirring unit 400 includes a stirring shaft 401, stirring blades 402, and a scraper 403. The central axis of the stirring shaft 401 is collinear with the second axis, and the stirring shaft 401 is used to connect to the third drive unit 320. The stirring blades 402 are connected to the peripheral wall of the stirring shaft 401 and extend radially along the stirring shaft 401. The scraper 403 is connected to the end of the stirring blades 402 away from the stirring shaft 401 and extends vertically, and the scraper 403 is used to contact the inner wall of the stirring tank 100. Obviously, multiple stirring blades 402 can be provided.

[0067] Based on the above configuration, when the stirring part 400 extends into the mixing tank 100, the stirring shaft 401 can be rotated to stir the material in the mixing tank 100 using the stirring blades 402, while the scraper 403 can scrape off the material on the inner wall of the mixing tank 100 to prevent the material from adhering to the inner wall of the mixing tank 100.

[0068] Based on the above configuration, in some specific embodiments, there are two sets of stirring blades 402, located on opposite sides of the stirring shaft 401. Each set of stirring blades 402 includes multiple stirring blades 402 arranged vertically at intervals. Two scrapers 403 are also provided, which are respectively connected to the two sets of stirring blades 402.

[0069] Reference Figure 1 and Figure 2As shown, in some embodiments of this utility model, a cover plate 310 is provided on the rotating part 300. The cover plate 310 is coaxially arranged with the stirring shaft 401 and the two can rotate relative to each other on the same axis. That is, when the stirring shaft 401 rotates, it will not drive the cover plate 310 to rotate. The stirring blade 402 and the scraper 403 are both located on the lower side of the cover plate 310. In the process of the lifting part 200 moving downward from the first position, the cover plate 310 can abut against the top of the stirring tank 100 to close the stirring tank 100. Specifically, when the lifting part 200 moves to the second position, the cover plate 310 can abut against the top of the stirring tank 100.

[0070] In some specific embodiments, the cover plate 310 is provided with a through hole for the stirring shaft 401 to pass through.

[0071] Based on the above configuration, when stirring the material in the mixing tank 100, the top of the mixing tank 100 can be sealed with the cover plate 310 to prevent the material from splashing out to the outside of the mixing tank 100.

[0072] Reference Figure 1 , Figure 3 and Figure 4 As shown, in some embodiments of this utility model, the extrusion section 500 includes an extrusion plate 501 and a sealing ring 502. The extrusion plate 501 is connected to the rotating section 300 and arranged horizontally. The extrusion plate 501 is used to extrude material downwards into the mixing tank 100 during discharge. The sealing ring 502 is disposed at the edge of the extrusion plate 501 and is distributed circumferentially along the extrusion plate 501. A sealing structure is provided on the circumference of the sealing ring 502. The sealing structure is used to contact the inner wall of the mixing tank 100 during discharge, thereby preventing material from leaking from between the extrusion section 500 and the inner wall of the mixing tank 100 to the upper side of the extrusion section 500 when the extrusion section 500 extrudes material downwards, ensuring that the material can be fully discharged.

[0073] Based on the above settings, in some specific embodiments, the sealing structure includes multiple sealing rings 503, which are arranged vertically at intervals and are all sleeved on the sealing ring 502.

[0074] Reference Figure 3 and Figure 4As shown, in some embodiments of this utility model, the extrusion part 500 is vertically slidably mounted on the rotation part 300 relative to the rotation part 300. An elastic part 600 is provided between the rotation part 300 and the extrusion part 500. The elastic part 600 is used to apply a downward elastic force to the extrusion part 500, that is, the extrusion part 500 has space for vertical elastic movement relative to the rotation part 300. The advantage of this arrangement is that, on the one hand, during the discharge process, when the extrusion part 500 extrudes the material downward, it can avoid excessive extrusion force that would cause the material to leak upward from between the extrusion part 500 and the inner wall of the mixing tank 100. On the other hand, it can also avoid the bottom end of the extrusion part 500 rigidly contacting the inner bottom wall of the mixing tank 100 and damaging the mixing tank 100, thus improving safety.

[0075] It should be noted that during the discharge process of mixing tank 100, when the lifting unit 200 is raised to the third position, if... Figure 3 As shown, the bottom end of the extrusion section 500 is in contact with the inner bottom wall of the mixing tank 100.

[0076] Reference Figure 3 and Figure 4 As shown, in some embodiments of this utility model, the extrusion plate 501 is provided with a plurality of slide rods 504. The slide rods 504 extend vertically and slide vertically through the rotating part 300. A limiting structure 505 is detachably connected to the slide rods 504. The limiting structure 505 is used to abut against the rotating part 300 to limit the downward displacement of the slide rods 504 relative to the rotating part 300 and prevent the slide rods 504 from disengaging from the rotating part 300. The above arrangement realizes the sliding connection between the extrusion part 500 and the rotating part 300, which is simple and reliable.

[0077] Reference Figure 4 As shown, in some embodiments of this utility model, the elastic part 600 is configured as a compression spring and sleeved on the slide rod 504. The upper and lower ends of the compression spring abut against the rotating part 300 and the pressing plate 501 respectively, thereby applying a downward elastic force to the pressing plate 501. The structure is simple and practical.

[0078] Obviously, since the limiting structure 505 is detachably provided on the slide bar 504, it is convenient to assemble and disassemble the pressing part 500 and the elastic part 600.

[0079] Reference Figure 4 As shown, in some embodiments of this utility model, the limiting structure 505 is configured as a limiting pin, which is horizontally inserted through the slide rod 504, resulting in a simple structure and convenient assembly and disassembly. Of course, in some embodiments, the limiting structure 505 can also be a limiting nut.

[0080] Reference Figures 1 to 3As shown, in some embodiments of this utility model, the mixing equipment for producing lubricating grease also includes a receiving bucket 700. The receiving bucket 700 is disposed on the frame 800, and the top of the receiving bucket 700 is open. When the mixing part 400 is located directly above the mixing tank 100, the extrusion part 500 is located directly above the receiving bucket 700; when the extrusion part 500 is located directly above the mixing tank 100, the mixing part 400 is located directly above the receiving bucket 700. It is understood that both the mixing part 400 and the extrusion part 500 may have material adhering to them after contact with the material. To prevent the material adhering to the mixing part 400 or the extrusion part 500 from dripping onto the frame 800 or the ground, this embodiment provides a receiving bucket 700. When the mixing part 400 is working, the receiving bucket 700 can be used to catch the material dripping from the extrusion part 500, and when the extrusion part 500 is working, the receiving bucket 700 can be used to catch the material dripping from the mixing part 400.

[0081] In addition, it should be noted that, in order to avoid excessive material adhering to the mixing part 400 and the extrusion part 500, when the mixing part 400 is removed from the mixing tank 100 after mixing, the mixing part 400 can be left to stand still directly above the mixing tank 100 for a period of time, so that the material with low adhesion on the mixing part 400 drips back into the mixing tank 100. Then, the rotating part 300 is rotated so that the extrusion part 500 moves to directly above the mixing tank 100.
