Description

Technical Field

[0001] This utility model relates to the field of lubricating grease dispensing, specifically a filtration device for dispensing lubricating grease. Background Technology

[0002] The filtration device for lubricating grease dispensing is a device used to remove impurities and ensure the purity of grease during the dispensing process. It can effectively filter out contaminants such as solid particles, metal shavings, and dust from the grease. The core part of the filter uses multi-layer filter screens or filter elements. The appropriate filtration precision is selected according to the viscosity of the grease and the size of the impurities. During the dispensing process, the grease is transported to the filter by the pump body. After being filtered layer by layer by the filter screens or filter elements, it enters the dispensing container to ensure the cleanliness and quality of the grease.

[0003] Chinese Patent Publication No. CN221964627U discloses a filter device for dispensing lubricating grease, including a box cover, locking mechanisms on the lower parts of both sides of the box cover, a feed pipe inserted into the middle of one side of the upper part of the box cover, a rotating mechanism in the middle of the upper part of the box cover, a connecting rod at the lower end of the rotating mechanism, and a mixing box at the lower end of the box cover. The lubricating oil is first put into the mixing box through the feed pipe on the box cover, and then the rotating mechanism on the box cover drives the mixing rod in the mixing box to stir the grease, preventing the grease from solidifying and sticking together, making the filtration more thorough and the grease more uniform, and facilitating the installation, fixing and disassembly of the filter plate.

[0004] When the aforementioned patented filtration device sends lubricating grease into the device for filtration, the filter plate used for filtration is not easy to replace temporarily. When replacing and cleaning the filter plate, it is necessary to stop supplying lubricating grease into the device, which causes the lubricating grease filtration to be interrupted and the filtration efficiency to be reduced. Utility Model Content

[0005] The purpose of this invention is to provide a filtration device for dispensing lubricating grease. Two filter cartridges are wrapped and restrained by a transmission disc. When adjusting the position of the filter cartridges, the transmission disc is driven to rotate, allowing the two cartridges to be interchanged. The replacement of the filter cartridges can be done directly by rotation. The transmission disc restricts the discharge of material from the temporary storage tank. When replacing the filter cartridges, it is not necessary to stop the delivery of lubricating grease to the feed pipe. The replaced filter cartridges can be directly removed from the support ring, facilitating cleaning and installation by the user. This invention solves the problems mentioned in the background section.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a filter device for dispensing lubricating grease, comprising a housing, a telescopic rod provided on one side of the upper end inside the housing, a second transmission rod and a transmission disc sequentially provided at the lower end of the telescopic rod, the telescopic rod and the second transmission rod being rotatably connected, support rings provided on both sides inside the transmission disc, a filter cartridge provided inside the support ring, and a suspension ring surrounding the upper end of the filter cartridge, a temporary storage tank provided in the middle inside the housing, an installation groove provided at the lower end of the temporary storage tank, the installation groove being connected to the upper end slot of the suspension ring, the transmission disc being pushed away from the temporary storage tank by the extension of the telescopic rod, facilitating the rotation of the transmission disc and the replacement of the filter cartridge after being away from the temporary storage tank.

[0007] Preferably, the second transmission rod is provided with a toothed groove around its outer side, and a meshing gear is provided on one side of the outer side of the toothed groove. The rotation of the gear can drive the second transmission rod with the toothed groove to rotate.

[0008] Preferably, a guide plate is provided on one side of the outer shell. The guide plate can wrap the filter cartridge that is replaced at the top, and receive and guide the lubricating grease that is retained inside the filter cartridge, so as to prevent the lubricating grease from not being able to flow to the filter plate after filtration.

[0009] Preferably, a protective cover is provided at the upper end of the filter cartridge, and the lower end of the protective cover is connected to the upper end of the guide plate through a slot, so that the upper area of ​​the guide plate can be wrapped by the protective cover.

[0010] Preferably, a filter plate is horizontally arranged at the lower end of the filter cartridge, and a mounting hole is provided at the front end of the filter plate. A handle is provided on one side outside the mounting hole, and the handle is welded and fixed to the filter plate. By holding the handle, the filter plate can be moved, so that the filter plate can be installed and removed along the mounting hole.

[0011] Preferably, a first transmission rod is provided on one side of the telescopic rod, and a motor is provided between the upper end of the first transmission rod and the outer shell. The transmission of the first transmission rod can drive the gear to rotate. When the gear rotates, it can continuously drive the second transmission rod with toothed grooves to rotate. The rotation of the second transmission rod can drive and adjust the position of the filter cartridge.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] In this invention, when lubricating grease is fed through the feed pipe for filtration, the grease is filtered one by one by the filter cartridge and filter plate. The filter plate can be quickly removed from the mounting hole by pulling the handle, allowing for rapid replacement and cleaning. Conversely, the extension and retraction of the telescopic rod and the rotation of the gears allow the lower mounting slot of the temporary storage tank to be removed from the transmission disc. After removal, rotation allows for direct replacement of the spare filter cartridge. The rotation of the transmission disc effectively restricts the material falling from the temporary storage tank, preventing unfiltered lubricating grease from falling directly from the tank during filter cartridge replacement, thus avoiding a decrease in filtration efficiency. Finally, the filter cartridge moves to the protective cover position as the transmission disc rotates. Removing the protective cover from the outer shell exposes the filter cartridge to be cleaned. The filter cartridge can then be removed longitudinally from the support ring, facilitating cleaning and replacement, improving filtration efficiency, and preventing any impact on the filtration effect.

Detailed Implementation

[0020] The present invention will be further described below with reference to specific embodiments.

[0021] like Figure 1 and Figure 2As shown, the filter device for dispensing lubricating grease in this embodiment includes a housing 1. A telescopic rod 7 is provided on one side of the upper end inside the housing 1. A second transmission rod 9 is provided at the lower end of the telescopic rod 7. A transmission disk 11 is provided at the lower end of the second transmission rod 9. The telescopic rod 7 and the second transmission rod 9 are rotatably connected. The lower end of the second transmission rod 9 is welded and fixed to the center position of the transmission disk 11. The extension of the telescopic rod 7, combined with the transmission of the second transmission rod 9, can drive the transmission disk 11 to adjust its longitudinal horizontal position. When the transmission disk 11 is adjusted to a horizontal position, the filter cartridge 13 can be replaced.

[0022] Among them, such as Figure 3 and Figure 5 As shown, a temporary storage tank 2 is provided in the middle of the inner shell 1. The lubricating grease is pre-filled into the temporary storage tank 2 before filtration. Support rings 12 are provided on both sides of the inner drive plate 11. Filter cylinder 13 is provided inside the support ring 12, and a suspension ring 14 is provided around the upper end of the filter cylinder 13. When installing and placing the filter cylinder 13, the filter cylinder 13 can be placed by resting on the upper end of the support ring 12 through the suspension ring 14. There is no additional structure to restrict the filter cylinder 13, which makes it easy to remove and replace the filter cylinder 13.

[0023] The lower end of the temporary storage tank 2 is provided with an installation groove 15, which is connected to the upper end slot of the suspension ring 14. The slot connection facilitates the stable transfer of the lubricating grease inside the temporary storage tank 2 to the filter cartridge 13 for filtration.

[0024] During the replacement of the filter cartridge 13, the circular drive disc 11 can fill and temporarily restrict the lower end of the temporary storage tank 2, so as to prevent the lubricating grease inside the temporary storage tank 2 from falling directly without being filtered when the filter cartridge 13 is replaced.

[0025] In order to provide power to the second transmission rod 9 so that it can drive the filter cartridge 13 at the lower end to rotate, the second transmission rod 9 is surrounded by a toothed groove 18. A gear 10 is provided on one side of the toothed groove 18, and the outside of the gear 10 is meshed with the toothed groove 18. The rotation of the gear 10 can drive the second transmission rod 9 to rotate through the toothed groove 18. The second transmission rod 9 and the toothed groove 18, which are longer than the gear 10, can continuously transmit power to the transmission disc 11 when the telescopic rod 7 extends and pushes the transmission disc 11, thus causing the transmission disc 11 to rotate.

[0026] Among them, a guide plate 6 is provided on one side of the outer shell 1. The filter cylinders 13 on both sides inside the transmission disk 11 are located at the lower end of the temporary storage tank 2 and the upper end of the guide plate 6, respectively. The filter cylinder 13 at the lower end of the temporary storage tank 2 is used to receive and filter the lubricating grease discharged from the temporary storage tank 2. The filter cylinder 13 that is rotated and replaced will move to the upper end of the guide plate 6. The lubricating grease retained inside the filter cylinder 13 can be filtered by the filter cylinder 13 and then guided by the guide plate 6 and flow towards the filter plate 16.

[0027] In addition, in order to cover the upper part of the guide vane 6, a protective cover 5 is provided on the upper part of the filter cartridge 13. The lower end of the protective cover 5 is connected to the upper end of the guide vane 6 through a slot. The protective cover 5 can be directly attached to the outside of the guide vane 6. The protective cover 5 protects the area of ​​the guide vane 6 and the filter cartridge 13 inside the area of ​​the guide vane 6. The filter cartridge 13 can be directly removed and cleaned after the protective cover 5 is removed, and the filter cartridge 13 can be replaced later.

[0028] In order to further filter the material filtered at the position of filter cartridge 13, a filter plate 16 is horizontally arranged at the lower end of filter cartridge 13. The lubricating grease filtered by filter cartridge 13 passes through filter plate 16 and completes the final filtration. A mounting hole 17 is provided at the front end of filter plate 16, and the mounting hole 17 penetrates the outer shell 1. The filter plate 16 can be installed and removed through the mounting hole 17.

[0029] Among them, such as Figure 4 As shown, a handle 4 is provided on one side of the mounting hole 17, and the handle 4 is welded and fixed to the filter plate 16. The user can remove and replace the filter plate 16 through the handle 4.

[0030] A feed pipe 3 is provided on one side of the upper end of the temporary storage tank 2. The lubricating grease to be filtered is sent into the temporary storage tank 2 through the feed pipe 3. The grease can be filtered and processed in the temporary storage tank 2.

[0031] In order to transmit and fix the gear 10, a first transmission rod 8 is provided on one side of the telescopic rod 7, and a motor is provided between the upper end of the first transmission rod 8 and the outer casing 1. The output shaft of the outer casing 1, the first transmission rod 8 and the upper end of the gear 10 are welded and fixed. The output shaft of the second transmission rod 9 can be driven by the motor to rotate the gear 10, and the rotation of the gear 10 can drive the second transmission rod 9 to rotate.

[0032] Working Principle: The device filters the lubricating grease. The lubricating grease is fed into the temporary storage tank 2 through the inlet pipe 3. After being filtered by the filter cylinder 13 and filter plate 16, the grease falls down and is discharged for subsequent dispensing. When the filter cylinder 13 needs to be replaced, the extension of the telescopic rod 7 causes the second transmission rod 9 to drive the transmission disc 11, support ring 12, and filter cylinder 13 to move longitudinally together. After the longitudinal movement, the temporary storage tank 2 loses connection with the lower filter cylinder 13. The motor at the upper end of the first transmission rod 8 is started. The motor drives the gear 10 to rotate through the first transmission rod 8. The gear 10 drives the second transmission rod 9 to rotate through the tooth groove 18. The rotation of the second transmission rod 9 drives the transmission disc 11 and filter cylinder 13 to rotate and replace the position of the filter cylinder 13, adjusting the corresponding filter cylinder at the lower end of the temporary storage tank 2. Position 13 allows the filter cartridge 13 previously located at the lower end of the temporary storage tank 2 to be replaced by the filter cartridge 13 at the lower end of the protective cover 5. During the replacement process, the rotation of the transmission disc 11 covers and restricts the lower end of the temporary storage tank 2 until the filter cartridge 13 is replaced. Then, the motor corresponding to the first transmission rod 8 stops starting, and the retraction of the telescopic rod 7 causes the mounting groove 15 at the lower end of the temporary storage tank 2 to be locked outside the suspension ring 14. The replaced filter cartridge 13 can be removed by removing the protective cover 5. The filter cartridge 13 can be cleaned and replaced. The grip at the handle 4 position allows the filter plate 16 to be removed from the mounting hole 17. The filter plate 16 can be replaced and cleaned. When cleaning the filter plate 16, the transmission disc 11 rotates to cover and restrict the lower end of the temporary storage tank 2, causing the filled lubricating grease to temporarily remain inside the temporary storage tank 2.
