Description

Technical Field

[0001] This invention relates to the field of petrochemical adsorption filter element devices, specifically to an adsorption type filter element oil filtration machine. Background Technology

[0002] The sum of polarization loss and conductivity loss caused by transformer oil under the action of an alternating electric field is collectively referred to as the dielectric loss factor. It sensitively reflects the quality of transformer insulation; the degree of aging of transformer oil under the influence of electric fields, oxidation, and high temperatures; and the degree of contamination from polar impurities and charged colloids in the oil. Colloidal impurities, microorganisms, and metal ions easily increase the dielectric loss factor. Before leaving the factory, transformers contain dust and impurities in the oil or solid insulation materials. After a period of operation, colloidal impurities gradually precipitate, easily leading to an increase in the dielectric loss factor. Microbial and bacterial infections mainly occur during installation and major overhauls, where flies, mosquitoes, and bacteria can easily penetrate the transformer oil and damage the dielectric. Wear or corrosion of the transformer's copper metal components (such as wear of the oil pump shaft or corrosion of exposed copper leads), severe overheating or burning of the coil copper wires, etc., can all cause copper ions to dissolve into the oil, increasing the copper ion concentration in the transformer oil and leading to increased dielectric loss. The existing methods for treating transformer oil with increased dielectric loss also have drawbacks. Increased dielectric loss leads to a decrease in transformer insulation, affecting the safe operation of the transformer. The usual method is to adsorb the impurities in the oil using a silica gel adsorption tank, and then filter out the remaining impurities through a filter element. However, this method has the following shortcomings: (1) When the adsorption tank treats dark-colored transformer oil, the silica gel adsorbent is easily saturated and cannot achieve the decolorization effect, and the dark-colored oil will dirty the transformer; (2) When the adsorption tank treats oil with a high acid value, the acid value of the transformer oil is reduced only to a limited extent, and the treatment effect is very poor; (3) When the adsorption tank treats oil with a high moisture content, the silica gel is easily saturated by water and loses its adsorption effect, and the silica gel will be crushed and clog the filter element; (4) After filtering for a period of time, the upper surface of the silica gel will move downward as a whole, and the oil will flow away quickly from the filter element without silica gel, resulting in a large portion of the oil not being adsorbed by the silica gel. These ordinary adsorption tanks can only treat dielectric loss to ensure that it does not exceed the range, but cannot completely constrain the dielectric loss from increasing. Moreover, for transformer oil with a good color, the amount of treatment agent used is large, and the investment cost is high.

[0003] Chinese patent CN206033681U discloses an adsorption filter element device, including a shell, an adsorption medium inlet at the upper end of the shell, a liquid outlet channel at the lower end of the shell, an adsorption medium layer, and an oil inlet filter element. The device is characterized by further including a lower end cap connected to the lower end of the liquid outlet channel and a central tube with openings at both ends. The lower end opening of the central tube is connected to the lower surface of the lower end cap, and the upper end is placed inside the shell and connected to the oil inlet filter element. The entire central tube passes through the lower end cap and the liquid outlet channel and is placed inside the shell. An oil outlet filter plate is provided on the bottom surface inside the shell. The adsorption medium layer is divided into three layers and sequentially filled within the space formed by the central tube and the shell.

[0004] Although the above solution can achieve the effects of decolorization and deodorization, the oil inlet filter element is located inside the device and has a filtering function. After a period of use, the oil inlet filter element will inevitably become clogged, requiring frequent maintenance. Furthermore, due to the limited installation location of the oil inlet filter element, it is not convenient to replace it. Summary of the Invention

[0041] To further understand the features, technical means, and specific objectives and functions achieved by the present invention, the present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments.

[0042] Reference Figures 1-13 An adsorption-type filter cartridge oil filtration machine includes a filter housing 1, a filter device 2, and a feed pipe 3. The filter device 2 includes a drive device 21, a transmission assembly 22, a filter assembly 23, and a cleaning assembly 24. The feed pipe 3 extends from the outside of the filter housing 1 into the inside of the filter housing 1. The drive device 21 is mounted on the feed pipe 3 located on the outside of the filter housing 1. The filter assembly 23 is rotatably mounted on one end of the feed pipe 3 located inside the filter housing 1 and is mounted through the side wall of the filter housing 1. The transmission assembly 22 is located below the filter assembly 23, and the drive device 21 drives the filter assembly 23 to rotate through the transmission assembly 22. The cleaning assembly 24 is located on the side of the filter assembly 23 away from the feed pipe 3 and is used to clean the filter assembly 23.

[0043] The bottom of the filter housing 1 has a discharge port, and the filter assembly 23 is connected to the discharge port through a connecting pipe. The filter housing 1 has multiple filter layers with baffles between them. The feed pipe 3 contains unfiltered oil. A pump body 241 is located on the side of the feed pipe 3 away from the filter housing 1. After the oil filter is started, the feed pipe 3, under the action of the pump body 241, transports the oil into the filter housing 1. The oil entering the filter housing 1 is filtered through multiple filter layers under the action of gravity and then flows out from the discharge port. Since the upper part of the feed pipe 3 is located on the filter assembly 23, the oil entering the filter housing 1 from the upper part of the feed pipe 3 will inevitably pass through the filter assembly 23. The filter assembly 23 can perform preliminary filtration on the passing oil, that is, filter out large particles of impurities in the oil. If the filter assembly 23 does not rotate at this time, after a period of use, a large amount of impurities will clog the filter assembly 23, which will cause the feed pipe 3 to become blocked. The flow rate of the oil entering the filter housing 1 decreases. To avoid affecting the flow rate, the filter assembly 23 can be rotated by the drive device 21. When the filter assembly 23 rotates, since it has a ring structure, impurities in the oil will not accumulate in the same place on the filter assembly 23, thereby increasing the amount of impurities that the filter assembly 23 can hold and extending the service life of the oil filter. However, even so, clogging will still occur after a long time. Therefore, a cleaning component 24 is set on the side of the filter assembly 23 away from the feed pipe 3. The cleaning component 24 can ensure that the impurities in the filter assembly 23 passing through the feed pipe 3 can be cleaned in time. This ensures that the filter assembly 23 is in a clean state before passing through the upper part of the feed pipe 3, so that the oil filter will not clog during the initial filtration of the oil and the maintenance cycle of the oil filter will be extended.

[0044] Reference Figure 1 , Figure 6 and Figure 9 The filter assembly 23 includes a drive disk 231, filter holes 232, a filter screen 233, and a sealing assembly 234. The drive disk 231 is disposed through the side wall of the filter housing 1 and is rotatably disposed on the upper part of the feed pipe 3. Multiple filter holes 232 are provided and are evenly distributed around the axis of the drive disk 231 on the upper part of the drive disk 231. The filter screen 233 is fixedly disposed on the filter holes 232. The sealing assembly 234 is a shell structure and is disposed on the outside of the drive disk 231. The sealing assembly 234 is used to ensure that the oil inside the filter housing 1 does not leak.

[0045] When the oil filter is started, the drive unit 21 drives the drive disk 231 to rotate through the transmission component 22. Since the drive disk 231 is provided with multiple filter holes 232, it is worth noting that the filter holes 232 will inevitably pass through the upper part of the feed pipe 3 under the drive of the drive disk 231. At the same time, when the filter holes 232 pass through the upper part of the feed pipe 3, the axis of the filter holes 232 is collinear with the axis of the feed pipe. When the feed pipe 3 discharges the oil into the filter shell 1, the oil will pass through the filter screen 233 on the filter holes 232. Larger impurities in the oil will be blocked by the filter screen 233. At the same time, due to the thrust of the oil, the impurities blocked by the filter screen 233 will not fall down. Thus, the impurities will be confined in the filter holes 232 and carried out with the rotation of the drive disk 231.

[0046] Reference Figure 3 , Figure 6 and Figure 10 The drive unit 21 includes a turbine 211 and a first toothed ring 212. The turbine 211 is rotatably mounted on the feed pipe 3. The first toothed ring 212 is rotatably mounted on the feed pipe 3 outside the turbine 211 along the axis of the turbine 211. The inner wall of the first toothed ring 212 is fixedly connected to the outer side of the blades of the turbine 211. The feed pipe 3 at the upper part of the first toothed ring 212 and the feed pipe 3 at the lower part of the first toothed ring 212 are connected by a connecting shell.

[0047] When the oil flows through the feed pipe 3, the turbine 211 installed on the feed pipe 3 will be driven to rotate by the oil because the oil has a certain pressure. Since the first toothed ring 212 is fixedly connected to the turbine 211, the first toothed ring 212 will also be driven to rotate after the turbine 211 is driven to rotate by the oil. Since the first toothed ring 212 is connected to the transmission component 22, the transmission component 22 will be driven.

[0048] Reference Figure 7 and Figure 8The transmission assembly 22 includes a first gear 221, a second gear 222, and a drive shaft 223. The first gear 221 is disposed on one side of the first gear ring 212, and the first gear 221 and the first gear ring 212 mesh with each other. The second gear 222 is disposed on the side of the first gear 221 away from the first gear ring 212. The axis of the second gear 222 is collinear with the axis of the drive disk 231. The second gear 222 meshes with the first gear 221, and there is a first gap between the second gear 222 and the drive disk 231. The drive shaft 223 is disposed in the first gap along the axis of the second gear 222, and both ends of the drive shaft 223 are fixedly connected to the second gear 222 and the drive disk 231, respectively.

[0049] When the first gear ring 212 rotates, the first gear 221 meshes with the first gear ring 212. Thus, when the first gear ring 212 rotates, the first gear 221 will also rotate. The second gear 222 meshes with the first gear 221. The second gear 222 and the drive disk 231 are fixedly connected by the drive shaft 223. Therefore, when the second gear 222 rotates, the drive shaft 223 on the second gear 222 will also drive the drive disk 231 to rotate.

[0050] Reference Figure 3 and Figure 5 The cleaning component 24 includes a pump body 241, a processing component 242, a return component 243, and an extension pipe 244. The pump body 241 is located above the drive disk 231 on the side away from the feed pipe 3, with its output end pointing vertically downward. A cleaning hole is provided through the sealing component 234 along the extension direction of the output end of the pump body 241. The pump body 241 and the cleaning hole at the top of the sealing component 234 are connected by a connecting pipe. The extension pipe 244 is located in the cleaning hole at the bottom of the sealing component 234. A base plate is horizontally arranged below the filter shell 1, and the extension pipe 244 passes through the base plate. The processing component 242 is located below the base plate, and the portion of the extension pipe 244 located below the base plate is located inside the processing component 242. The return component 243 is located between the processing component 242 and the feed pipe 3, and is used to drain the oil in the processing component 242 back into the feed pipe 3.

[0051] After the drive disc 231 is driven to rotate by the drive device 21, the filter screen 233 on the drive disc 231 will rotate to the outside of the filter shell 1 after passing the upper part of the feed pipe 3. It is worth noting that the filter hole 232 in the rotating state will inevitably pass through the extension pipe 244. The axis of the extension pipe 244 is collinear with the axis of the connecting pipe, and when the filter hole 232 passes through the extension pipe 244, the axis of the filter hole 232 and the axis of the extension pipe 244 are collinear. Since the drive disc 231 is fitted with a sealing component 234 on the outside, when the filter hole 232 on the drive disc 231 passes through the feed pipe 3, the filter hole 232 and the sealing component 234 will form a... The sealed space temporarily traps impurities on the filter screen 233. As the drive disc 231 rotates, when it passes the extension pipe 244, the pump body 241 pumps clean oil into the connecting pipe. The oil then enters the filter hole 232 through the connecting pipe. At this time, the impurities on the filter screen 233 are pushed downwards. Thus, driven by the oil in the connecting pipe, the oil and impurities in the filter hole 232 enter the extension pipe 244 and eventually flow into the processing component 242. After being processed by the processing component 242, the oil flows back into the feed pipe 3 through the return component 243. It is worth noting that the bottom of the filter shell 1 is provided with a discharge port. The clean oil filtered by the filter shell 1 flows out through the discharge port at the bottom of the filter shell 1. The input and output of the pump body 241 are connected to the discharge port through the connecting pipe, so the pump body 241 can obtain clean oil.

[0052] Reference Figure 9 , Figure 11 , Figure 12 and Figure 13 The processing component 242 includes a working outer shell 2421, a working inner shell 2422, a second gear ring 2423, and a guide plate 2424. The second gear ring 2423 is rotatably mounted on a substrate along the axis of the extension tube 244. The substrate has a through hole extending through the axis of the extension tube 244. The second gear ring 2423 meshes with the second gear 222. The working inner shell 2422 is fixedly mounted on the lower part of the second gear ring 2423 through the through hole. Filter holes are provided on the side wall of the working inner shell 2422. The working outer shell 2421 is located at the bottom of the substrate surrounding the working inner shell 2422. Multiple guide plates 2424 are provided and are uniformly fixedly mounted on the inner peripheral wall of the working inner shell 2422 around the axis of the working inner shell 2422.

[0053] When the drive device 21 is started, the second gear 222 is driven to rotate, which causes the second gear ring 2423, which meshes with the second gear 222, to rotate. Since the inner working shell 2422 is fixedly set at the bottom of the second gear ring 2423 and the inner working shell 2422 has a circular barrel structure, while the outer working shell 2421 is fixedly set at the lower part of the base plate, the outer working shell 2421 remains stationary when the second gear ring 2423 drives the inner working shell 2422 to rotate. An inclined guide plate 2424 is provided inside the inner working shell 2422. When the inner working shell 2422 rotates, the guide plate 2424 guides the oil in the inner working shell 2422 to move towards the peripheral wall of the inner working shell 2422 under the action of centrifugal force. The inner working shell 2422 has a filtering function. Thus, when the oil moves to the peripheral wall of the inner working shell 2422, the oil will pass through the inner working shell 2422, while impurities in the oil will not pass through the inner working shell 2422.

[0054] Reference Figure 4 and Figure 5 The reflux assembly 243 includes a reflux pipe 2431 and a one-way valve 2432; the reflux pipe 2431 is disposed between the working housing 2421 and the feed pipe 3; the one-way valve 2432 is disposed on the side of the reflux pipe 2431 near the feed pipe 3.

[0055] When the pump body 241 draws the oil into the processing component 242, the oil pressure inside the processing component 242 will rise because the processing component 242 already contains oil. As a result, the oil in the processing component 242 will flow into the feed pipe 3 through the return pipe 2431. The one-way valve 2432 installed on the return pipe 2431 is to prevent the oil in the feed pipe 3 from flowing back into the processing component 242 through the return pipe 2431.

[0056] Reference Figure 6 and Figure 7 The sealing assembly 234 includes a first sealing shell 2341 and a second sealing shell 2342. The first sealing shell 2341 is sleeved on the side of the drive disk 231 located inside the filter shell 1 and is fixedly connected to the inner wall of the filter shell 1. The second sealing shell 2342 is sleeved on the side of the drive disk 231 located outside the filter shell 1 and is fixedly connected to the outer wall of the filter shell 1.

[0057] By setting up a first sealing shell 2341 and a second sealing shell 2342, the oil is always inside the first sealing shell 2341 and the second sealing shell 2342 when the drive disc 231 rotates, ensuring that the oil in the filter shell 1 will not leak due to the drive disc 231 being in a rotating state.

[0058] Reference Figure 7 and Figure 8The filter device 2 also includes a water-permeable component, which includes water-permeable holes 235, water-permeable grooves 236, and an insulating filter plate 237. Multiple water-permeable holes 235 are provided, and the water-permeable holes 235 are evenly opened around the axis of the drive disk 231 on the side of the filter hole 232 near the center of the drive disk 231. The water-permeable grooves 236 are opened along the height direction of the filter shell 1 on the first sealing shell 2341. The insulating filter plate 237 is provided on the upper part of the water-permeable grooves 236, and the insulating filter plate 237 is provided with filter holes.

[0059] When the oil enters the filter housing 1 through the filter assembly 23, the sealing assembly 234 will hinder the filtration of the oil. By setting the water permeable hole 235 and the water permeable groove 236, the oil can be better circulated. The isolation filter plate 237 set on the water permeable groove 236 is to ensure that the filter layer material on the upper part of the sealing assembly 234 will not enter the hole of the water permeable groove 236.

[0060] Reference Figure 8 The filter device 2 also includes a bracket 25; the bracket 25 is fixedly mounted on the filter housing 1 and is used to provide support for the drive shaft 223.

[0061] By setting the bracket 25, the rotation of the drive shaft 223 can be ensured to be more stable.

[0062] The above embodiments only illustrate one or more implementations of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this patent should be determined by the appended claims.
