Description

Technical Field

[0001] This utility model relates to the field of waste oil purification technology, specifically a filter component for purifying high-cleanliness waste oil. Background Technology

[0002] High-cleanliness waste oil refers to waste oil that has undergone special treatment and purification to remove most of the impurities and harmful substances, reaching a certain cleanliness standard. This type of waste oil can be reused or safely disposed of to reduce environmental pollution and resource waste. Waste oil purification machines are usually used for waste oil processing.

[0003] When filter bags filter waste oil without effective cleaning, they may clog the purification filter assembly. This is because waste oil contains solid impurities and requires pre-filtration. The filter bag removes these solid impurities from the bag. However, the oil residue on the surface of the impurities increases their viscosity, causing them to adhere to the inner wall of the filter bag and form clumps. This hinders oil penetration and affects the filtration effect. Therefore, a high-cleanliness waste oil purification filter assembly is proposed here. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a filter assembly for purifying high-cleanliness waste oil. It has advantages such as easy cleaning and solves the problem that waste oil contains solid impurities, requiring pre-filtration. While the filter bag removes solid impurities, residual oil on the surface of the impurities increases their viscosity, causing them to adhere to the inner wall of the filter bag and form clumps, thus hindering oil penetration and affecting the filtration effect.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a filter assembly for high-cleanliness waste oil purification, comprising a filter assembly disposed inside the main body of the purifier for high-cleanliness filtration and impurity removal of waste oil;

[0006] The filtration assembly includes a filter cartridge disposed inside the purifier body, and a filter bag is disposed inside the filter cartridge to perform multiple filtrations of waste oil through the cooperation of the filter bag and the filter cartridge. A sealing cover is disposed on the top of the purifier body, and a cleaning component is fixedly disposed on the bottom of the sealing cover.

[0007] The cleaning component includes two support plates, the tops of which are fixed to the bottom of the sealing cap and are located inside the filter bag. Each support plate has an interior cavity containing a corrugated tube. The tops of the corrugated tubes are connected to the inner top walls of the two cavities, and the bottoms of the corrugated tubes have connecting blocks. Scraper rings are fixed to the outer sides of the connecting blocks to clean impurities from the inner wall of the filter bag. Return springs are vertically installed inside the corrugated tubes to return the connecting blocks to their original positions. Air pipes, each connected to one of the corrugated tubes, are located on the outer sides of the two support plates.

[0008] Furthermore, the purifier body is equipped with a flow collection hood located below the filter cartridge, and the outside of the flow collection hood is connected to an oil drain valve for collecting and exporting the filtered oil.

[0009] Furthermore, the upper surface of the sealing cap is connected to a pressure boosting pipe, and a pressure gauge is installed on the outside of the pressure boosting pipe. The inside of the pressure boosting pipe is filled with nitrogen gas to apply pressure to the waste oil to accelerate filtration.

[0010] Furthermore, guide openings are provided on both the front and rear sides of the two support plates, and two connecting blocks are slidably disposed inside the two guide openings to drive the scraper ring to move along a specified path.

[0011] Furthermore, each of the two air tubes is connected to a reversing valve at the end furthest from the bellows to control the inflow and outflow of gas inside the bellows.

[0012] Furthermore, pressure plates are fixedly provided at the bottom of the two support plates, and the diameter of the pressure plates is equal to the diameter of the scraper ring, so as to spread the filter bag and make it fit against the filter cylinder.

[0013] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0014] This filter assembly for high-cleanliness waste oil purification applies pressure to the waste oil through a booster pipe, accelerating the permeation efficiency and thus improving the filtration speed and overall filtration efficiency. The filter cartridge and filter bag work together to effectively remove solid impurities from the waste oil, achieving a high-cleanliness purification effect. By purifying waste oil, it reduces environmental pollution and contributes to environmental protection. Through the cooperation of corrugated pipes, connecting blocks, and scraper rings, it achieves automatic cleaning of impurities on the inner wall of the filter bag, reducing the need for manual cleaning, preventing filter bag clogging, and extending the service life of the filter bag.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example 1: Please refer to Figure 1-2 The filter assembly for high-cleanliness waste oil purification in this embodiment includes a filter assembly 2 disposed inside the purifier body 1 for high-cleanliness filtration and impurity removal of waste oil.

[0023] In this embodiment, the purifier body 1 is provided with a flow collection hood 3 located below the filter cartridge 21, and the outside of the flow collection hood 3 is connected to an oil drain valve for collecting and exporting the filtered oil.

[0024] Example 2: Please refer to Figure 2-5 Based on Embodiment 1, the filter assembly 2 in this embodiment includes a filter cartridge 21 disposed inside the purifier body 1, and a filter bag 22 is disposed inside the filter cartridge 21, so that the waste oil can be filtered multiple times by the filter bag 22 and the filter cartridge 21 working together. The waste oil is introduced into the filter cartridge 21 inside the purifier body 1. After the waste oil enters the filter cartridge 21, it is filtered by the filter bag 22. A sealing cover 23 is disposed on the top of the purifier body 1, and a cleaning component 24 is fixedly disposed at the bottom of the sealing cover 23.

[0025] The cleaning component 24 includes two support plates 241. The top ends of the two support plates 241 are fixed to the bottom of the sealing cover 23, and the two support plates 241 are located inside the filter bag 22. The interior of each support plate 241 has a cavity 242, and the interior of each cavity 242 is provided with a corrugated tube 243. The top ends of the two corrugated tubes 243 are respectively connected to the inner top wall of the two cavities 242, and the bottom ends of the two corrugated tubes 243 are provided with connecting blocks 244. Scraper rings 245 are fixed to the outside of the two connecting blocks 244 to clean impurities from the inner wall of the filter bag 22. The interior of each corrugated tube 243 is vertically provided with a return spring 246 to drive the connecting block 244 back to its original position. The outside of each support plate 241 is provided with an air pipe 247 that is connected to the two corrugated tubes 243 respectively.

[0026] In this embodiment, the upper surface of the sealing cover 23 is connected to a pressure boosting pipe, and a pressure gauge is installed on the outside of the pressure boosting pipe. The inside of the pressure boosting pipe is filled with nitrogen gas to apply pressure to the waste oil to accelerate filtration. The pressure boosting pipe is connected to an external compressed air source to introduce nitrogen gas into the purifier body 1. By applying pressure to the waste oil with nitrogen gas, the permeability of the waste oil is accelerated, thereby achieving the purification and filtration of the waste oil.

[0027] In this embodiment, guide openings are provided on both the front and rear sides of the two support plates 241, and two connecting blocks 244 are slidably disposed inside the two guide openings to drive the scraper ring 245 to move along a designated path. The ends of the two air pipes 247 away from the bellows 243 are connected to reversing valves to control the inflow and outflow of gas inside the bellows 243. The air pipe 247 connected to the external air pump is opened periodically, and the reversing valve controls the gas flow direction. When the reversing valve switches to the input state, compressed air is delivered into the bellows 243. The compressed air pushes the bellows 243 to expand within the cavity 242, and during the expansion process, it pushes the connecting... The connecting block 244 and the scraper ring 245 move along the inner wall of the filter bag 22. The scraper ring 245 scrapes off the impurities adhering to the inner wall of the filter bag 22, thus cleaning the filter bag 22. The bottom of the two support plates 241 is fixedly provided with pressure plates 248, and the diameter of the pressure plates 248 is equal to the diameter of the scraper ring 245, so as to spread the filter bag 22 so that it fits against the filter cylinder 21. After cleaning, the reversing valve reverses to discharge the gas. The reset spring 246 pulls the connecting block 244 and the others back to their original position and compresses the bellows 243 again for the next operation. The filtered oil is collected through the collector 3 and then discharged through the drain valve.

[0028] It should be noted that the pressure plate 248 is fixed to the bottom of the support plate 241, and its diameter is equal to that of the scraper ring 245. It is used to spread the filter bag 22 so that it fits into the filter cartridge 21 and improves the filtration efficiency.

[0029] The working principle of the above embodiments is as follows:

[0030] Waste oil is introduced into the filter cartridge 21 inside the purifier body 1. After entering the filter cartridge 21, the waste oil is filtered through the filter bag 22. The oil permeates the filter bag 22, leaving solid impurities inside. The booster pipe is connected to an external compressed air source, introducing nitrogen into the purifier body 1. The nitrogen applies pressure to the waste oil, accelerating its permeation efficiency and achieving purification and filtration. The air pipe 247, connected to an external air pump, is periodically opened. A reversing valve controls the gas flow direction. When the reversing valve switches to the input state, compressed air is delivered into the bellows 243. The compressed air pushes the bellows 243 to expand within the cavity 242. During the expansion process, the connecting block 244 and the scraper ring 245 are pushed to move along the inner wall of the filter bag 22. The scraper ring 245 scrapes off the impurities adhering to the inner wall of the filter bag 22, thus cleaning the filter bag 22. After cleaning, the reversing valve reverses to discharge the gas. The return spring 246 pulls the connecting block 244 back to its original position and compresses the bellows 243 again for the next operation. The filtered oil is collected through the collector 3 and then discharged through the drain valve. The pressure plate 248 is fixed to the bottom of the support plate 241. Its diameter is equal to that of the scraper ring 245. It is used to spread the filter bag 22 so that it fits into the filter cylinder 21, thereby improving the filtration efficiency.
