Description

Technical Field

[0001] The invention relates to the technical field of grease processing, in particular to an industrial grease high-efficiency grinding and filtering device and an operating method thereof. Background Art

[0002] Industrial grease is a lubricating material composed of an oil base and a thickener. It is usually a viscous semi-fluid or solid. It can form a protective film between mechanical parts that need lubrication to reduce friction and improve the operating efficiency of mechanical equipment, thereby extending the service life of mechanical equipment. The main functions of grease are lubrication, protection and sealing. Most greases are semi-solid substances with unique fluidity. Most greases are used for lubrication and are called anti-friction greases. Anti-friction greases mainly reduce mechanical friction and prevent mechanical wear. At the same time, they also protect against metal corrosion and seal against dust. Some greases are mainly used to prevent Greases used to prevent metals from rusting or corroding are called protective greases, such as industrial vaseline. There are also a few greases specifically used for sealing, called sealing greases, such as thread grease. The working principle of grease is that the thickener keeps the oil in the position where lubrication is needed. When there is a load, the thickener releases the oil, thereby playing a lubricating role. At room temperature and in a static state, it is like a solid and can maintain its shape without flowing, and can adhere to metal without slipping. At high temperatures or when subjected to external forces exceeding a certain limit, it can flow like a liquid, and when affected by moving parts in a machine, it can reduce friction and wear between moving surfaces. When the action stops, it can restore a certain viscosity.

[0003] However, in the current production process of industrial grease, the grease is often ground in two rounds by a grinding disc and a grinding roller. In fact, for grease, especially synthetic oil-based grease, more rounds of fine grinding are required to ensure the quality of synthetic oil-based grease. In the existing grinding device, if the quality of the grease is to be improved, the grease needs to be repeatedly ground. Moreover, since the existing grinding device cannot freely adjust the number of grinding times, the grease needs to be repeatedly poured into the feed hopper manually for grinding, which is troublesome and inefficient. In addition, during the grinding process, since the grease has a large viscosity, the existing methods such as gravity and vibration cannot make it enter the grinding area quickly, which may affect the overall grinding efficiency.

[0004] For example, Chinese patent announcement number: CN215541222U discloses a multi-stage grinding device for industrial grease, including a machine base and a support frame, the support frame is installed on the upper surface of the machine base, and a grinding assembly, a material guide assembly and a grinding roller are installed in the support frame from top to bottom in sequence, the material guide assembly includes a material guide hopper, a first spring seat, a cushion block, a second spring seat and a vibration motor, the two side walls of the opening end of the material guide hopper are fixedly connected to the first spring seat, the first spring seat is fixedly connected to the second spring seat through the cushion block, the second spring seat is installed on the inner wall of the support frame, and the vibration motor is fixedly connected to the front position of the material guide hopper. By installing the grinding assembly and the grinding roller inside the support frame, the grease is subjected to secondary grinding processing to improve the accuracy and product quality; however, this technical solution still cannot freely adjust the number of grinding times of the grease. If the grinding quality is to be improved, it is still necessary to manually pour the ground grease into the device repeatedly for re-grinding, which greatly reduces the low production efficiency of the grease.

[0005] Therefore, how to automatically and repeatedly grind industrial grease to improve the quality and efficiency of grease production is a technical problem that technicians currently need to solve. Summary of the invention

DETAILED DESCRIPTION

[0036] The following will be combined with the drawings in the specification of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0037] Please refer to the attached Figure 1 , Attachment Figure 3 , Attachment Figure 4 and attached Figure 7 The embodiment of the present invention provides an industrial grease high-efficiency grinding and filtering device and an operating method thereof, comprising a chassis 1, a housing 2 is fixedly connected to the top of the chassis 1, a grinding mechanism 3 is arranged in the middle of the housing 2, and a pressing mechanism 4 is arranged in the upper part of the housing 2;

[0038] The grinding mechanism 3 includes a fixed plate 301, the outer side of the fixed plate 301 is fixedly connected to the middle part of the shell 2, a plurality of inclined grooves 302 are provided inside the fixed plate 301, a transmission rod 303 is rotatably connected to the middle part of the fixed plate 301, a grinding head 304 is fixedly connected to the upper outer part of the transmission rod 303, a receiving pool 305 is rotatably connected to the lower outer part of the transmission rod 303, a driven wheel 306 is fixedly connected to the bottom end of the transmission rod 303, and driving wheels 307 are meshed on both sides of the driven wheel 306, and servo motors 308 are fixedly connected to both sides of the bottom end of the shell 2, and the servo motors 308 on both sides are meshed with driving wheels 307 on both sides. The output ends of the servo motors 308 pass through the shell 2 and are fixedly connected to the bottom end of the driving wheel 307. Hollow tubes 309 are fixedly connected on both sides of the shell 2. Spiral blades 310 are rotatably connected inside the hollow tubes 309 on both sides. Rotating rods 311 are fixedly connected to the middle of the spiral blades 310 on both sides. The bottom ends of the rotating rods 311 on both sides pass through the hollow tubes 309 and are fixedly connected to the top end of the driving wheel 307. The sides of the hollow tubes 309 that are close to each other are fixedly connected with inclined tubes 312. The ends of the inclined tubes 312 that are close to each other are respectively fixedly connected to the two sides of the receiving pool 305.

[0039] The funnel-shaped housing 2 can be separated into two parts, the upper and lower parts, by the fixing plate 301, so as to prevent the grease from falling directly along the inner surface of the housing 2 to the receiving pool 305. At the same time, the evenly distributed inclined grooves 302 can provide a channel for the ground grease to be transferred to the lower part of the housing 2. When the servo motors 308 on both sides are started, the driving wheels 307 on both sides can rotate synchronously to drive the driven wheel 306 to rotate together. At the same time, since the driven wheel 306 is connected to the transmission rod 303, the transmission rod 303 can obtain the power output by the servo motor 308 to drive the grinding head 304 to rotate continuously. Because there is a certain distance between the fixed disk 301 and the grinding head 304, and the truncated cone-shaped grinding head 304 is not in contact with the housing 2, the grease that gradually slides along the inner surface of the housing 2 to the area where the fixed disk 301 and the grinding head 304 are located under the action of gravity can gradually enter the area between the fixed disk 301 and the grinding head 304 under the push of the subsequent grease to be ground, and then the ground grease can pass through the fixed disk 301 through the inclined grooves 302 evenly distributed inside the fixed disk 301 and close to the transmission rod 303 and fall into the receiving pool directly below. 305, and at the same time, since the receiving pool 305 is connected to the hollow tube 309 through the inclined inclined tube 312, when the grease inside the receiving pool 305 accumulates to a certain extent, it can slide into the hollow tube 309 along the inclined tube 312. Furthermore, since the driving wheel 307 is also connected to the spiral blade 310 through the rotating rod 311, the spiral blade 310 can continuously transfer the grease entering the hollow tube 309 upward while rotating along the inner surface of the hollow tube 309, until it is transferred to the upper part of the shell 2 along the hollow tube 309, and at this time, the ground grease can slide along the inner surface of the shell 2 again. The grease is re-ground toward the fixed disk 301 and the grinding head 304, and before the servo motor 308 stops working, the grease inside the shell 2 can be repeatedly ground and transferred. In summary, any type of grease can be ground any number of times and for any time, which improves the practicability of the device, and the grinding and transfer processes can be carried out automatically without human intervention, reducing the demand for manpower. In addition, there must be a certain height difference between the upper outlet of the hollow tube 309 and the middle area of ​​the funnel-shaped shell 2, so that the grease can be directly collected from the upper outlet of the hollow tube 309 after the grinding requirements are met.

[0040] Please refer to the attached Figure 7 The grinding head 304 is located above the fixed disk 301 , and a plurality of support blocks 313 are fixedly connected to the bottom end of the fixed disk 301 . The plurality of support blocks 313 are fixedly connected to the inside of the housing 2 at the far side.

[0041] Since the grinding head 304 is located above the fixed disk 301, it can be ensured that the grease first passes through the area where the grinding head 304 is located, and then is retained by the fixed disk 301, so that the grinding head 304 can further grind the grease retained by the fixed disk 301. In addition, the evenly distributed support blocks 313 can provide support for the fixed disk 301 to enhance the connection strength between the fixed disk 301 and the shell 2, and then the fixed disk 301 can improve the stability of the transmission rod 303 during rotation, thereby preventing the transmission rod 303 from shaking during rotation due to its long length.

[0042] Please refer to the attached Figure 3 -Attached Figure 5 The bottom end of the receiving pool 305 is fixedly connected with a disc 314, the middle part of the disc 314 is rotatably connected to the outside of the transmission rod 303, the outside of the disc 314 is fixedly connected to the lower part of the shell 2, and the bottom ends of the hollow tubes 309 on both sides are fixedly connected to the top of the disc 314.

[0043] The housing 2 can provide support for the disc 314. Similarly, the disc 314 can provide support for the transmission rod 303, the receiving pool 305 and the hollow tube 309, so that they can all function stably and avoid deviation or shaking that affects normal use.

[0044] Please refer to the attached Figure 3 and attached Figure 4 The outer sides of the bottom ends of the driving wheels 307 on both sides are rotatably connected to the limit ring 1 315, and the bottom ends of the limit ring 1 315 on both sides are fixedly connected to the bottom end inside the shell 2. The bottom end of the driven wheel 306 is rotatably connected to the limit ring 2 316, and the bottom end of the limit ring 2 316 is fixedly connected to the middle part of the bottom end inside the shell 2.

[0045] The driving wheel 307 and the driven wheel 306 can be supported and limited by the limiting ring 1 315 and the limiting ring 2 316 respectively to ensure that they will not be displaced when the driving wheel 307 and the driven wheel 306 rotate, so that the driving wheel 307 and the driven wheel 306 can always maintain effective meshing.

[0046] Please refer to the attached Figure 3 -Attached Figure 5 A truncated table 317 is fixedly connected to the bottom end of the receiving pool 305, the middle part of the truncated table 317 is rotatably connected to the outside of the transmission rod 303, the top of the truncated table 317 is rotatably connected to a sleeve 318, the middle part of the sleeve 318 is fixedly connected to the outside of the transmission rod 303, the front and rear sides of the sleeve 318 are fixedly connected to T-shaped scrapers 319, the side of the T-shaped scraper 319 away from the sleeve 318 is slidably connected to the front and rear sides of the receiving pool 305 respectively, and a retaining ring 320 is fixedly connected to the top of the receiving pool 305.

[0047] The contact area between the transmission rod 303 and the receiving pool 305 can be increased by the frustum 317, thereby also improving the stability of the transmission rod 303 during movement, and the inclined surface of the frustum 317 can be used to accelerate the grease to slide toward the inclined tube 312, and the sleeve 318 can be used to transmit the power output by the transmission rod 303 to the T-shaped scraper 319, and further, the T-shaped scraper 319 can be made to rotate synchronously with the transmission rod 303 to scrape the inner surface of the receiving pool 305, so as to prevent part of the grease from being unable to enter the hollow tube 309 due to the distance from the inclined tube 312, thereby preventing the part of the grease from failing to be ground multiple times, and in addition, the inwardly inclined retaining ring 320 can prevent the T-shaped scraper 319 from cleaning the grease on the inner surface of the receiving pool 305, and part of the grease from being squeezed and pushed away from the receiving pool 305.

[0048] Please refer to the attached Figure 4 and attached Figure 6 The top ends of the rotating rods 311 on both sides are rotatably connected with baffles 321 , and the outer sides of the baffles 321 on both sides are fixedly connected to the upper inner part of the hollow tube 309 .

[0049] The hollow tube 309 can provide support for the baffle 321, and the baffle 321 can cooperate with the continuously rotating rotating rod 311 and spiral blade 310 to push the grease inside the hollow tube 309 away from the hollow tube 309. At the same time, the baffle 321 can cooperate with the hollow tube 309 to jointly limit the movement trajectory of the rotating rod 311 to prevent the rotating rod 311 and spiral blade 310 from shaking during movement.

[0050] Please refer to the attached Figure 4 , Attachment Figure 5 , Attachment Figure 8 and attached Fig. 9 The pressing mechanism 4 includes a rotating disk 401, the bottom end of which is fixedly connected to the top of the transmission rod 303, a plurality of arc-shaped inclined blocks 402 are fixedly connected to the outer side of the top of the rotating disk 401, and the tops of the plurality of arc-shaped inclined blocks 402 are slidably connected to push rods 403, a connecting disk 404 is arranged on the upper inner part of the shell 2, the tops of the plurality of push rods 403 are fixedly connected to the bottom of the connecting disk 404, a pressing cylinder 405 is fixedly connected to the outer side of the bottom end of the connecting disk 404, the pressing cylinder 405 is directly opposite to the grinding head 304, and a counterweight 406 is fixedly connected to the outer side of the top of the connecting disk 404.

[0051] The power output by the transmission rod 303 can be transmitted to the arc-shaped inclined blocks 402 evenly distributed on its upper surface through the rotating disk 401. Since the upper surfaces of the arc-shaped inclined blocks 402 have a certain slope, when the transmission rod 303 drives the rotating disk 401 and the arc-shaped inclined blocks 402 to rotate, the push rods 403 matched with the arc-shaped inclined blocks 402 can be pushed to move up along the upper surface of the arc-shaped inclined blocks 402 until they move to the top of the upper surface of the arc-shaped inclined blocks 402. Then, when the transmission rod 303, the rotating disk 401 and the arc-shaped inclined blocks 402 continue to rotate, each push rod 403 can fall to the lowest point on the upper surface of the next arc-shaped inclined block 402. Then, when the push rod 403 makes a vertical reciprocating linear motion along the upper surface of the arc-shaped inclined blocks 402, the lower pressing cylinder 405 can be driven to move synchronously through the connecting disk 404. When the push rod 403 moves downward, the lower pressure cylinder 405 facing the grinding head 304 can slide down along the inner wall of the middle part of the funnel-shaped shell 2 and press the grease in the area toward the fixed plate 301 and the grinding head 304 to prevent the grease from sliding slowly toward the fixed plate 301 and the grinding head 304 due to its high viscosity, thereby avoiding affecting the overall grinding efficiency due to viscosity. At the same time, the squeezing of the lower pressure cylinder 405 can also accelerate the grease to pass through the inclined groove 302. When the lower pressure cylinder 405, the connecting plate 404 and the push rod 403 move upward and leave the middle area of ​​the funnel-shaped shell 2, the grease in the upper part of the shell 2 can continue to slide toward the fixed plate 301 and the grinding head 304. In addition, the weight of the counterweight block 406 can increase the pressure applied to the grease by the lower pressure cylinder 405, thereby ensuring that the lower pressure cylinder 405 can effectively push the grease downward.

[0052] Please refer to the attached Figure 2 , Attachment Figure 5 and attached Figure 8 A cross plate 407 is slidably connected to the middle of the connecting disk 404, a cross plate 408 is fixedly connected to the top of the cross plate 407, and both sides of the cross plate 408 are fixedly connected to the tops of both sides of the shell 2.

[0053] The transverse plate 408 can be fixed by the shell 2, and the transverse plate 408 can prevent the cross plate 407 from being displaced. Furthermore, the connecting plate 404 can be guided by the cross plate 407 to prevent the connecting plate 404, the push rod 403 and the lower pressure cylinder 405 from rotating and being unable to move up and down normally when affected by the arc-shaped inclined block 402, the transmission rod 303, etc.

[0054] Please refer to the attached Figure 5 , Attachment Figure 8 and attached Fig. 9A second truncated table 409 is fixedly connected to the outer side of the bottom end of the turntable 401, and the middle part of the second truncated table 409 is fixedly connected to the outer side of the transmission rod 303. The middle part of the bottom end of the lower pressure cylinder 405 is slidably connected to the outer side of the transmission rod 303. A guide frame 410 is slidably connected to the outer side of the lower pressure cylinder 405, and the top of the guide frame 410 is fixedly connected to the bottom end of the horizontal plate 408.

[0055] The contact area between the turntable 401 and the transmission rod 303 can be increased by using the second frustum 409 to prevent the connection between the turntable 401 and the transmission rod 303 from being broken due to excessive force. At the same time, the guide frame 410 can be used to guide the lower pressure cylinder 405, and the movement of the lower pressure cylinder 405 along the transmission rod 303 can further ensure the stability of the transmission rod 303. In addition, the guide frame 410 can also be used to scrape off the grease adhered to the surface of the lower pressure cylinder 405 when the lower pressure cylinder 405 moves upward.

[0056] An operating method of an industrial grease high-efficiency grinding and filtering device comprises the following operating steps:

[0057] S1: Pour the grease to be ground into the housing 2, use the curvature of the inner surface of the housing 2 to make the grease slide toward the fixed plate 301 and the grinding head 304, start the servo motor 308, drive the driven wheel 306 to rotate through the driving wheel 307, and at the same time, make the rotating plate 401 drive each arc-shaped inclined block 402 to rotate through the transmission rod 303, so that each push rod 403 drives the connecting plate 404 and the lower pressing cylinder 405 to move up and down;

[0058] S2: After the lower pressure cylinder 405 pushes the grease close to the fixed plate 301 and the grinding head 304, the fixed plate 301 cooperates with the grinding head 304 rotating with the transmission rod 303 to grind the grease, and at the same time, the ground grease falls into the receiving pool 305 along the inclined grooves 302 under the pressure of the lower pressure cylinder 405;

[0059] S3: The grease inside the receiving pool 305 enters the hollow tube 309 through the inclined tube 312, and at the same time, the spiral blade 310 is driven to rotate through the rotating rod 311 connected to the driving wheel 307 to transfer the grease entering the hollow tube 309 to the upper part of the shell 2, and cooperate with the baffle 321 to make the grease leave the hollow tube 309 and slide back to the fixed plate 301 and the grinding head 304.

[0060] Working principle: When in use, the servo motor 308 is started, so that the driving wheel 307 can simultaneously drive the driven wheel 306 and the rotating rod 311 to rotate, wherein the driven wheel 306 can drive the rotating disk 401 and the evenly distributed arc-shaped inclined blocks 402 to rotate through the transmission rod 303, and since the upper surface of the arc-shaped inclined blocks 402 has a certain slope, the push rod 403 can only drive the connecting disk 404 and the lower pressure cylinder 405 to do reciprocating up and down motion under the cooperation of the cross plate 408, the cross plate 407, the guide frame 410 and the connecting disk 404, and then the lower pressure cylinder 405 can be used to push the grease to accelerate to approach the fixed disk 301 and the grinding head 304, so as to avoid the grease from moving slowly due to its high viscosity, thereby preventing the overall grinding efficiency from being affected, and at the same time, the grinding head 304 connected to the transmission rod 303 can also cooperate with the fixed disk 301 during the rotation process to grind the nearby grease, and because the inclined groove 3 02 is in the overlapping area of ​​the fixed disk 301 and the grinding head 304 and is close to the transmission rod 303, so only the ground grease can pass through the fixed disk 301 through the evenly distributed inclined grooves 302 and fall into the receiving pool 305. Further, when the grease inside the receiving pool 305 accumulates to a certain extent, it can slide to the hollow tube 309 through the inclined tube 312 under the action of gravity. At the same time, since the rotating rod 311 inside the hollow tube 309 is also connected to the spiral blade 310, the grease entering the hollow tube 309 can be continuously transferred upward along the hollow tube 309 through the continuously rotating spiral blade 310 until it returns to the upper area inside the shell 2 from the upper part of the hollow tube 309. At this time, this part of the grease can be re-ground to ensure that it meets the required quality through multiple grindings, and the grinding, transfer and pressing processes do not require manual intervention, and there is no need to add a power source, which is more in line with the development concept of green production.
