Description

Technical Field

[0001] This utility model relates to the field of lubrication pumps, and more particularly to a filter device for a dual-line grease lubrication pump. Background Technology

[0002] A dual-line grease lubrication pump is a lubrication device that injects grease into various lubrication points by alternating operation of two oil supply lines. Its working principle is that the pump alternately pressurizes the two main pipelines through the switching action of a reversing valve. When one pipeline is supplying oil, the other pipeline is in a depressurized state, thereby achieving the flow and distribution of grease.

[0003] A dual-line grease lubrication pump typically consists of core components such as a pump body, a reversing valve, a dual-line distribution valve, and a terminal pressure switch. The pump body is the main part of the lubrication pump, responsible for generating pressure and driving grease flow; the reversing valve is used to switch the working state of the two oil supply lines; the dual-line distribution valve is responsible for distributing grease to each lubrication point; and the terminal pressure switch is used to monitor system pressure and control the pump's start and stop.

[0004] During circulation, lubricating oil inevitably carries metal shavings, dust, and other impurities. If these impurities directly enter the lubrication system, they will accelerate component wear and even lead to equipment failure. Therefore, a filtration device is essential to maintain the cleanliness of the lubricating oil and the normal operation of the system. In related technologies, some existing dual-line grease lubrication systems only have a coarse filtration function, resulting in poor filtration efficiency. Furthermore, most existing filtration devices for lubrication pumps are difficult to disassemble and clean, leading to decreased effectiveness after a period of use and requiring time-consuming and labor-intensive cleaning.

[0005] Therefore, it is necessary to provide a dual-line grease lubrication pump filtration device to solve the above-mentioned technical problems. Utility Model Content

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0023] Please refer to the following: Figure 1 , Figure 2 , Figure 3 and Figure 4 ,in Figure 1 A schematic diagram of a preferred embodiment of the dual-line grease lubrication pump filter device provided by this utility model; Figure 2 for Figure 1 A structural schematic diagram of a partial cross-sectional view of the oil storage tank shown; Figure 3 for Figure 2 The diagram shows a structural schematic of the front view of the oil storage tank section.

[0024] Figure 4 for Figure 3 The structural schematic diagram of the right cross-sectional view of the connecting block shown is a dual-line grease lubrication pump filter device, including: a lubrication pump body 1, and a filter assembly 2 provided on the top of the lubrication pump body 1.

[0025] The filter assembly 2 includes an oil reservoir 21 located on the top left side of the lubrication pump body 1. A cover plate 22 is provided on the top of the oil reservoir 21. An oil filter pipe 23 is provided on the top of the cover plate 22. A connecting block 24 is provided on the right side of the oil filter pipe 23. A coarse filter screen 25 is engaged inside the connecting block 24.

[0026] With the setting of the coarse filter 25, when the lubricating oil enters the oil filter pipe 23, the larger particles of impurities inside the lubricating oil will be intercepted by the coarse filter 25.

[0027] The inner wall of the oil tank 21 is provided with a partition plate 26, the bottom of the partition plate 26 is provided with a filter cylinder 27, the inner wall of the oil tank 21 and above the partition plate 26 is provided with a protrusion 28, and a fine filter screen 29 is provided above the protrusion 28.

[0028] The fine filter 29 is designed to intercept and filter small particles of impurities inside the lubricating oil, preventing damage to the pump body. The protrusion 28 allows the fine filter 29 to be easily lifted for cleaning.

[0029] A sliding rod 3 is vertically arranged on the inner side of the connecting block 24. An insert plate 4 is arranged on the periphery of the sliding rod 3, which can slide up and down along its height direction. A screw 5 is vertically arranged on the top of the connecting block 24, which can rotate. The bottom end of the screw 5 is rotatably connected to the top of the insert plate 4. When the bottom end of the insert plate 4 slides down, it will be inserted into the top of the coarse filter screen 25.

[0030] When disassembling and cleaning the coarse filter screen 25, the bottom plate 4 can be raised by rotating the screw 5, thereby disengaging the bottom of the plate 4 from the coarse filter screen 25 and pulling the coarse filter screen 25 forward. When installing and fixing it, the operation is reversed.

[0031] A cleaning brush 6 is rotatably mounted on the top of the fine filter 29, and a connecting rod 7 is mounted on the bottom of the cleaning brush 6. The bottom end of the connecting rod 7 passes through the top of the fine filter 29 and extends to its bottom.

[0032] By cleaning brush 6, large accumulations of clogging particles can be broken down into smaller accumulations, thereby extending the service life of fine filter 29 and reducing the frequency of cleaning.

[0033] The top of the partition plate 26 is equipped with a drive motor 8 for driving the cleaning brush 6 to rotate, and the output end of the top of the drive motor 8 is engaged with the bottom end of the connecting rod 7.

[0034] When the connecting rod 7 and the top output end of the drive motor 8 are connected, the top output end of the drive motor 8 is block-shaped and inserted into the groove opened at the bottom of the connecting rod 7, so that when the output end of the drive motor 8 rotates, it can drive the connecting rod 7 and the cleaning brush 6 to rotate.

[0035] Both sides of the cover plate 22 are provided with buckles 9, and the right side of the connecting block 24 is provided with a detachable oil inlet pipe 10.

[0036] The oil inlet pipe 10 can be connected to the right side of the connecting block 24 via a quick-connect pipe fitting or a flange, thus ensuring ease of disassembly and sealing after installation.

[0037] The working principle of the dual-line grease lubrication pump filter device provided by this utility model is as follows:

[0038] Step 1: During use, lubricating oil enters the oil filter pipe 23 through the oil inlet pipe 10. During this process, the lubricating oil passes through the inside of the connecting block 24, and under the action of the coarse filter screen 25, larger particles of impurities inside the lubricating oil are intercepted. When the lubricating oil enters the oil storage tank 21, the fine filter screen 29 can intercept and filter smaller particles of impurities inside the lubricating oil. Finally, the lubricating oil is above the partition plate 26 and finally passes through the fine filtration of the filter cylinder 27 before being supplied to the lubrication pump body 1.

[0039] Step 2: When disassembling and cleaning the coarse filter 25, the bottom plate 4 can be raised by rotating the screw 5, thereby disengaging the bottom of the plate 4 from the coarse filter 25, and pulling the coarse filter 25 forward for cleaning. When the fine filter 29 filters slowly, the drive motor 8 can be started to drive the connecting rod 7 and the cleaning brush 6 to rotate, thereby the cleaning brush 6 will concentrate and accumulate the small particles distributed on the top of the fine filter 29, thus reducing the cleaning cycle of the fine filter 29. At the same time, when disassembling the fine filter 29, the cover plate 22 can be removed by the clip 9, and the fine filter 29 and the cleaning brush 6 can be pulled out directly for cleaning.

[0040] Compared with related technologies, the dual-line grease lubrication pump filtration device provided by this utility model has the following advantages:

[0041] Beneficial effects:

[0042] By setting up a coarse filter screen 25, a fine filter screen 29, and a filter cylinder 27, the device can filter impurities inside the lubricating oil in a step-by-step manner, thereby improving the filtration effect and service life of the filter device. At the same time, the setting of a detachable fine filter screen 29, a connecting block 24, and a cover plate 22 makes it convenient to disassemble a certain filter screen and improves the performance.
