Description

Technical Field

[0001] This utility model relates to the field of filter element clogging and flushing, specifically to a waste oil precision filter element clogging and flushing assembly. Background Technology

[0002] Filter cartridge clogging flushing refers to the process of removing blockages and restoring filter cartridge performance when the filtration efficiency of a filter cartridge decreases due to the accumulation of impurities. This is achieved through physical methods such as backwashing, forward washing, or chemical cleaning. The core principle is to remove deposits from the surface of the filter cartridge through reverse water flow, airflow, or mechanical action, ensuring the continuous and effective operation of the filtration system. The waste oil precision filter cartridge clogging flushing component is an automated device specifically designed for treating high-viscosity, high-impurity waste oils such as lubricating oil and hydraulic oil in waste oil precision filtration systems. Its core function is to extend the life of the filter cartridge through efficient flushing, ensuring filtration accuracy and system stability.

[0003] Existing waste oil precision filter cartridge clogging flushing components lack multi-stage synergistic flushing capabilities during use. This means that a single flush cannot remove the tiny particles embedded in the filter cartridge pores. Furthermore, a single method requires manual disassembly of the filter cartridge for deep cleaning. Under long-term use, when emulsified oil and metal particles are present in the waste oil, a single physical flush cannot break the emulsion and is insufficient to flush away solid particles. This further reduces the adaptability of waste oil precision filter cartridge clogging flushing components and limits the process.

[0004] Therefore, it is necessary to invent a waste oil precision filter cartridge clogging flushing assembly to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a waste oil precision filter cartridge clogging flushing assembly. This assembly, consisting of a waste oil filter cartridge, a tank cover, a vacuum pump, a self-cleaning air rod, an inner flushing chamber, an outer flushing chamber, a chemical tank, and a cleaning water tank, enables multi-stage coordinated flushing. This design allows gas to impact the inside of the filter cartridge, preventing internal bridging blockage, while high-pressure water flushing removes external residues, achieving thorough cleaning. Furthermore, the multi-stage coordinated flushing significantly improves cleaning efficiency compared to single-stage methods, enhances filter cartridge pressure differential recovery, and prevents dirt accumulation. The problem of filter element deformation or puncture is addressed by improving the adaptability of this waste oil precision filter element clogging flushing assembly to complex waste oil conditions. This solves the problem that existing waste oil precision filter element clogging flushing assemblies lack multi-stage synergistic flushing capabilities, resulting in single flushing being unable to remove tiny particles embedded in the filter element pores. Moreover, a single method requires manual disassembly of the filter element for deep cleaning. Under long-term use, when there are emulsified oil and metal particles in the waste oil, single physical flushing cannot break the emulsion and is difficult to flush away solid particles. This also reduces the adaptability and process limitations of the waste oil precision filter element clogging flushing assembly.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a waste oil precision filter element clogging flushing assembly, including a flushing filter tank and a main body for flushing the filter element;

[0007] An inner sliding groove is formed on the inner wall of the flushing filter tank for internal sliding connection of an inner sliding plate. A positioning groove is formed on the upper part of each inner sliding plate. A positioning block is embedded in the positioning groove. A funnel ring is fixedly installed on the upper part of the positioning block. A waste oil filter element is fixedly installed inside the funnel ring.

[0008] A can lid is fixedly installed on top of the rinsing filter can to seal the can body. A vacuum pump is fixedly installed on top of the can lid. An air supply pipe is fixedly installed on the output end of the vacuum pump. An inlet is fixedly connected to the other end of the air supply pipe. A self-cleaning air rod is fixedly installed at the bottom of the inlet. An inner cleaning head is fixedly installed on the outside of the self-cleaning air rod.

[0009] An inner flushing chamber is fixedly installed inside the flushing filter tank for flushing the inside of the filter element. An outer flushing chamber is fixedly installed inside the flushing filter tank. A chemical tank is fixedly installed outside the flushing filter tank. A first pressurized water pump is fixedly installed above the chemical tank. A cleaning water tank is fixedly installed outside the flushing filter tank. A second pressurized water pump is fixedly installed above the cleaning water tank.

[0010] Preferably, the bottom of the rinsing filter tank is provided with a drain outlet and the bottom of the rinsing filter tank is provided with a filter outlet.

[0011] Preferably, the positioning block fixedly installed at the bottom of the funnel ring engages with the positioning grooves opened on the top of the inner slide plate, and the positioning block and the positioning grooves are used in conjunction.

[0012] Preferably, a sealed cavity is fixedly installed on both sides of the inside of the rinsing filter tank, and a telescopic cylinder is fixedly installed inside the sealed cavity. An outer ring scraper is fixedly installed on the top of the telescopic cylinder.

[0013] Preferably, the output end of the first pressurized water pump is fixedly connected to the outside of the inner flushing chamber, and the output end of the second pressurized water pump is fixedly connected to the outside of the outer flushing chamber.

[0014] Preferably, flushing nozzles are fixedly installed on the exterior of both the inner and outer flushing cavities, and the flushing nozzles are arranged in a ring array on the inner and outer flushing cavities.

[0015] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0016] This utility model includes a waste oil filter element, a tank cover, a vacuum pump, a self-cleaning air rod, an inner flushing chamber, an outer flushing chamber, a chemical tank, and a cleaning water tank. When the waste oil precision filter element becomes clogged in the flushing assembly, the vacuum pump first supplies a certain amount of gas to the self-cleaning air rod. The air rod then passes through the inner cleaning head inside the waste oil filter element, impacting some of the dirt adhering to it. The gas impact removes loose dirt from the filter element surface, reducing the load on subsequent processing. Then, the dissolving agent sprayed from the inner flushing chamber dissolves the stubborn dirt on the waste oil filter element. The chemical agent specifically dissolves stubborn sludge or carbon deposits, overcoming the limitations of simple physical flushing. The system then flushes the waste oil filter element from the outside through the external flushing chamber, while the self-cleaning air column continues to flush the inside of the waste oil filter element through airflow. This combined use gives the waste oil precision filter element clogging flushing component a multi-stage synergistic flushing capability. This design allows the gas to impact the inside of the filter element, preventing bridging blockage inside the filter element, and the external high-pressure water flushing removes external residues, achieving thorough cleaning. Moreover, the cleaning efficiency of multi-stage synergistic flushing is significantly improved compared to a single method, and the filter element pressure differential recovery rate is also improved. At the same time, thorough cleaning avoids problems such as filter element deformation or puncture caused by dirt accumulation, and also makes the waste oil precision filter element clogging flushing component adaptable to complex waste oil working conditions.

[0025] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0026] This utility model provides, for example Figure 1-5 The waste oil precision filter cartridge clogging flushing assembly shown includes a flushing filter tank 1 and a main body for flushing the filter cartridge;

[0027] The inner slide groove 4 is opened on the inner wall of the flushing filter tank 1 and is used to slide the inner slide plate 5 inside. The upper part of the inner slide plate 5 is provided with a positioning groove 6. The positioning groove 6 is inlaid with a positioning block 7. The upper part of the positioning block 7 is fixedly installed with a funnel ring 8. The inside of the funnel ring 8 is fixedly installed with a waste oil filter element 9.

[0028] The can lid 10 is fixedly installed on the top of the flushing filter can 1 to seal the can body. A vacuum pump 11 is fixedly installed on the top of the can lid 10. An air supply pipe 12 is fixedly installed at the output end of the vacuum pump 11. An inlet 13 is fixedly connected to the other end of the air supply pipe 12. A self-cleaning air rod 14 is fixedly installed at the bottom of the inlet 13. An inner cleaning head 15 is fixedly installed on the outside of the self-cleaning air rod 14.

[0029] The inner flushing chamber 19 is fixedly installed inside the flushing filter tank 1 for flushing the inside of the filter element. The outer flushing chamber 20 is fixedly installed inside the flushing filter tank 1, and the chemical tank 21 is fixedly installed outside the flushing filter tank 1. A first pressurized water pump 22 is fixedly installed above the chemical tank 21. A cleaning water tank 23 is fixedly installed outside the flushing filter tank 1, and a second pressurized water pump 24 is fixedly installed above the cleaning water tank 23. The dissolving agent sprayed from the inner flushing chamber 19 dissolves the stubborn dirt on the waste oil filter element 9. The chemical agent specifically dissolves stubborn sludge or carbon deposits, breaking through the limits of single physical flushing. Then, the outer flushing chamber 20 flushes the waste oil filter element 9 from the outside. The self-cleaning air rod 14 continues to flush the inside of the waste oil filter element 9 through airflow. With this combination, the waste oil precision filter element clogging flushing component has the ability of multi-stage coordinated flushing.

[0030] like Figure 1 , Figure 2 and Figure 3 As shown, the bottom of the flushing filter tank 1 is provided with a drain port 2 and a filter outlet 3. The drain port 2 and the filter outlet 3 can be switched by an electromagnetic control valve, which facilitates the flushing and drainage of the internal filter element. The positioning block 7 fixedly installed at the bottom of the funnel ring 8 is engaged with the positioning groove 6 opened on the top of the inner slide plate 5. The positioning block 7 and the positioning groove 6 are used in conjunction. The funnel ring 8 is installed above the waste oil filter element 9, which not only facilitates the installation and use of the waste oil filter element 9 inside the flushing filter tank 1, but also facilitates the concentrated flow of sprayed agents into the filter element.

[0031] like Figure 1 , Figure 4 and Figure 5 As shown, sealed cavities 16 are fixedly installed on both sides of the inner flushing filter tank 1. Telescopic cylinders 17 are fixedly installed inside the sealed cavities 16. An outer ring scraper 18 is fixedly installed on the top of the telescopic cylinder 17. The telescopic cylinder 17 can drive the outer ring scraper 18 to the outside of the waste oil filter element 9, assisting in scraping away external dirt during the cleaning of the waste oil filter element 9. The output end of the first pressurized water pump 22 is fixedly connected to the outside of the inner flushing cavity 19, and the output of the second pressurized water pump 24... The end is fixedly connected to the outside of the outer flushing chamber 20. The dissolving agent sprayed from the inner flushing chamber 19 dissolves the stubborn dirt on the waste oil filter element 9. The chemical agent specifically dissolves stubborn sludge or carbon deposits, breaking through the limit of single physical flushing. Both the inner flushing chamber 19 and the outer flushing chamber 20 are fixedly installed with flushing nozzles 25. The flushing nozzles 25 are arranged in a ring array on the inner flushing chamber 19 and the outer flushing chamber 20. The outer flushing chamber 20 flushes the waste oil filter element 9 from the outside.

[0032] The working principle of this utility model is as follows: First, connect the external power supply, take out the waste oil filter element 9 that needs to be flushed, and insert the waste oil filter element 9 directly into the inner slide plate 5 through the funnel ring 8 for fixation. Then, insert the self-cleaning air rod 14 of the canister cap 10 into the inside of the waste oil filter element 9. This allows the flushing work to begin on the clogged waste oil precision filter element. First, the vacuum pump 11 can supply a certain amount of air to the self-cleaning air rod 14, allowing the self-cleaning air rod 14 to pass through the inner cleaning head 15 inside the waste oil filter element 9, impacting a portion of the clogged waste oil. The dirt on filter element 9 is loosened by gas impact and peeled off, reducing the load on subsequent treatment. Then, the switch of the first pressurized water pump 22 on the chemical tank 21 is turned on, allowing the first pressurized water pump 22 to provide a certain amount of chemical agent to the inner flushing chamber 19. The dissolving agent sprayed through the inner flushing chamber 19 dissolves the stubborn dirt on the waste oil filter element 9. The chemical agent specifically dissolves stubborn sludge or carbon deposits, breaking through the limitations of single physical flushing. Then, the switch of the second pressurized water pump 24 on the cleaning water tank 23 is turned on, allowing the outer flushing chamber 20 to flush the waste oil filter element 9 from the outside. During the rinsing process, the self-cleaning air column 14 continues to rinse the inside of the waste oil filter element 9 through airflow. Simultaneously, the telescopic cylinder 17 drives the outer ring scraper 18 to scrape away external dirt from the waste oil filter element 9. Then, the filter outlet 3 is closed, and the drain outlet 2 is opened, allowing the cleaned dirt and wastewater to flow out together through the drain outlet 2. This design provides the waste oil precision filter element clogging rinsing assembly with multi-stage coordinated rinsing capabilities. This design allows gas to impact the inside of the filter element, preventing internal bridging blockage and external blockage. High-pressure water flushing removes external residues, achieving thorough cleaning. The multi-stage synergistic flushing significantly improves cleaning efficiency compared to a single method, and also enhances the filter element pressure differential recovery rate. After completing the installation and use of the waste oil precision filter element clogging flushing assembly according to the above procedures, turn off the vacuum pump 11, the telescopic cylinder 17, and the first and second pressurized water pumps 22 and 24. If not in use for an extended period, simply disconnect the external power supply. This completes the usage process of the waste oil precision filter element clogging flushing assembly.

Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
