Description

Technical Field

[0001] This utility model relates to the field of filter technology, and in particular to a basket filter for waste mineral oil treatment. Background Technology

[0002] Waste mineral oil treatment refers to the process of purifying, regenerating, or rendering harmless mineral oil that has been contaminated by foreign impurities after use in various industries, businesses, or daily life, through a series of physical and chemical methods. Basket filters are a type of industrial coarse or protective filtration equipment with a simple structure and wide application.

[0003] A search revealed a basket filter with publication number CN223453868U. This basket filter includes a cylinder, a cover, and a filter basket. The cylinder has a first flange at the top, and the cover includes a second flange and a feed pipe connected to the interior of the filter basket. The filter basket has a top-mounted filter basket flange, located between the first and second flanges and cooperating to seal the filter basket. By shifting the installation position of the filter basket flange to between the first and second flanges, the sealing surface between the filter basket and the cylinder is ensured to be evenly subjected to the force from the cover, preventing material from seeping into the sealing surface between the filter basket and the cylinder and being discharged through the discharge pipe without filtration. Furthermore, the feed pipe is appropriately positioned within the cover to connect to the interior of the filter basket, ultimately improving the sealing performance between the filter basket and the cylinder without affecting the filtration process.

[0004] The device in this patent is prone to clogging of the filter basket when the filter particle size is small and the pollution load is high, which affects the continuous operation capability and has low practicality. Utility Model Content

[0005] In response to the technical problems in existing patents, such as the filter basket holes being easily clogged when the filter particle size is small and the pollution load is high, requiring frequent rinsing or replacement of the filter basket, which affects the continuous operation capability and has low practicality, this utility model provides a basket filter for waste mineral oil treatment.

[0028] The following is in conjunction with the appendix Figure 1-5 The present invention will be further described below.

[0029] To address the problems existing in the background art, this application proposes the following technical solution:

[0030] A basket filter for treating waste mineral oil includes: a filter cartridge 1 and an anti-clogging component 4;

[0031] A first motor 2 is bolted to the top of the filter cartridge 1. A filter basket 3 is fixedly mounted on the output shaft of the first motor 2. An oil inlet pipe 5 is installed on one side of the filter cartridge 1. A slag outlet pipe 6 and an oil outlet hole are opened at the bottom of the filter cartridge 1.

[0032] like Figure 1-5 As shown, the anti-clogging component 4 is installed inside the filter cartridge 1. The anti-clogging component 4 is used to prevent oil residue from clogging the filter basket 3.

[0033] The anti-clogging component 4 includes a positioning structure 401 installed on the top of the filter cartridge 1, a scraper 402 installed at the bottom of the positioning structure 401, and a backwashing structure 403 installed inside the filter basket 3. The positioning structure 401 includes a boss 4011 fixedly welded to the top of the filter cartridge 1, a disassembly and assembly component 4012 installed inside the boss 4011, an auxiliary seat 4013 installed on the top of the filter cartridge 1, and an assembly component 4014 installed on one side of the auxiliary seat 4013.

[0034] Furthermore, the boss 4011 has a reset groove inside, and the disassembly and assembly part 4012 includes a reset plate 8 fused to the inner wall of the reset groove by a reset spring 7 and a limiting post 9 and a disassembly and assembly post 10 fixedly welded to one side of the reset plate 8.

[0035] Furthermore, the assembly 4014 includes a positioning plate 11 fixedly welded to one side of the auxiliary seat 4013 and a positioning block 12 fixedly welded to one side of the positioning plate 11. The positioning block 12 has a limiting hole 13, and the limiting post 9 cooperates with the limiting hole 13.

[0036] Furthermore, the backwashing structure 403 includes a liquid storage tank 4031 installed on the top of the filter basket 3 and a spray column 4032 installed at the bottom of the inner top wall of the filter basket 3.

[0037] Furthermore, an oil outlet pipe 14 and a liquid outlet pipe 15 are fixedly welded inside the filter basket 3. The oil outlet pipe 14 is rotatably installed inside the oil outlet hole. An adjustment hole 16 is opened at the top of the filter cylinder 1. A cylinder 17 is installed inside the auxiliary seat 4013. A scraper 402 is fixedly installed on the output shaft of the cylinder 17. The scraper 402 cooperates with the adjustment hole 16. A scraper brush is installed on one side of the scraper 402. The function of the scraper brush is to mechanically destroy the "filter cake layer" attached to the outer wall of the filter basket 3, peel it off from the surface of the filter basket 3, and turn it into loose particles.

[0038] Furthermore, all valves in the pipelines are electric valves, and their opening and closing are controlled by the device's control panel.

[0039] Working principle: When in use, waste mineral oil is pumped into filter cartridge 1 through oil inlet pipe 5 and filtered through filter holes on filter basket 3. Impurities are isolated on the outer wall of filter basket 3. The filtered oil is discharged through oil outlet pipe 14, and the impurity oil is discharged through sludge outlet pipe 6 for the next filtration.

[0040] During the filtration process, the first motor 2 drives the filter basket 3 to rotate, thereby improving the utilization efficiency of the filter basket 3;

[0041] When the filtration efficiency is reduced due to the adhesion of impurities, the first-level cleaning mode can be activated: the scraper plate 402 is pushed by the cylinder 17, and the scraper plate 402 moves in the adjustment hole 16 and fits against the outer wall of the filter basket 3. During the rotation of the filter basket 3, the scraper on the scraper plate 402 is used to scrape and clean the outer wall of the filter basket online. This mode can effectively scrape off the loose filter cake and restore part of the filtration capacity without interrupting the main process.

[0042] If the filtration efficiency still does not meet the requirements after the first-stage cleaning, the second-stage cleaning mode, namely the backwashing mode, is activated: at this time, the valves of the oil outlet pipe 14 and the oil inlet pipe 5 are closed, and the valves of the liquid outlet pipe 15 and the sludge outlet pipe 6 are opened. The cleaning liquid in the liquid storage tank 4031 is sprayed outward from the inside of the filter basket 3 through the spray column 4032 under high pressure. At the same time, the scraper of the scraper plate 402 works together to perform high-intensity composite cleaning on the outer surface of the filter basket 3. The cleaned oil sludge and waste liquid are discharged through the sludge outlet pipe 6.

[0043] By using graded cleaning, the cleaning method can be flexibly selected according to the actual working conditions, ensuring filtration efficiency while reducing interruptions to continuous production, avoiding frequent rinsing, and reducing the consumption of cleaning media.

[0044] The reset plate 8 is moved by the disassembly column 10, the reset plate 8 squeezes the reset spring 7, and the reset plate 8 moves the limit column 9. The relative position of the limit column 9 and the limit hole 13 is controlled, thereby controlling the relative position of the boss 4011 and the positioning block 12. This facilitates the disassembly and assembly of the auxiliary seat 4013 and the boss 4011, and makes it convenient to repair and replace the scraper plate 402 after it is worn.

[0045] One optimized technical solution is that the blade of the scraper adopts a specific sweep angle design. Its working principle is not vertical extrusion, but when the filter basket 3 rotates, it generates a tangential and downward combined force on the impurities, thereby quickly guiding the scraped impurities away from the surface of the filter basket 3 and avoiding local accumulation.

[0046] All standard parts used in this utility model can be purchased from the market, and irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art.
