Description

Technical Field

[0001] This invention relates to the field of cleaning equipment technology, and in particular to a cleaning device for oil-contaminated filter media. Background Technology

[0002] In scenarios such as cleaning oily filter media in industrial wastewater treatment, regenerating cutting fluid in machining, cleaning exhaust gas filter media in automotive painting workshops, treating oily sludge in sewage treatment plants, and maintaining oil-gas separation filter media in petrochemical plants, cleaning devices for oily contaminated filter media are often needed to precisely control cleaning efficiency, filter media regeneration rate, anti-clogging properties, automation level, water conservation and environmental protection, and equipment durability.

[0003] Existing cleaning devices for oil-contaminated filter media have significant shortcomings in terms of cleaning effectiveness and ease of oleophobic layer maintenance. Their cleaning methods are relatively simple, often relying on direct rinsing, which fails to effectively remove stubborn oil contaminants adhering to the filter media and wire mesh surfaces, resulting in poor cleaning performance. Direct rinsing only removes surface oil and cannot penetrate the pores of the filter media and the gaps in the wire mesh, easily leading to oil residue. This not only affects the subsequent filtration efficiency and lifespan of the filter media but also increases the workload and water consumption of repeated cleaning. Furthermore, the oleophobic layer on the wire mesh surface gradually wears down after repeated rinsing. Existing equipment often uses manual spraying to replenish the oleophobic layer, which is cumbersome and prone to uneven application. Excessively thick oleophobic layers in some areas can lead to buildup, while thin layers fail to achieve effective oleophobicity, causing oil to re-adhere to the wire mesh surface, accelerating filter media contamination, further reducing the overall operating efficiency of the cleaning device, and increasing labor costs and material losses during equipment maintenance.

[0030] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0031] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0032] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments.

[0033] Example 1, referring to Figure 1 and Figure 2 This is the first embodiment of the present invention. This embodiment provides a cleaning device for oil-contaminated filter media. The cleaning device for oil-contaminated filter media includes a cleaning component 1 and an auxiliary component 2.

[0034] Through the collaborative design of cleaning component 1 and auxiliary component 2, the shortcomings of oil-contaminated filter media cleaning devices, such as poor cleaning effect, cumbersome maintenance of oleophobic layer, and easy re-adhesion of oil, are effectively solved. On the one hand, the single direct rinsing mode is abandoned, and a cleaning process of strong rinsing and soaking separation is constructed to meet the oil cleaning needs of filter media and metal wire mesh: first, the surface floating oil is removed by low-pressure spraying, then the excess floating oil is removed by soaking cleaning, and stubborn oil-containing pollutants are decomposed. Finally, the cleaning is completed by hot air drying, eliminating oil residue, improving the subsequent filtration efficiency of filter media, and extending service life. On the other hand, the oleophobic layer recoating mode is optimized to replace manual spraying, avoid the problems of local accumulation or excessively thin spraying, ensure effective oleophobic effect, delay the re-adhesion of oil, and reduce the rate of filter media contamination.

[0035] Specifically, the cleaning assembly 1 includes a cleaning tank 11, a movable door 12 is movably connected to one side of the cleaning tank 11, a soaking component 13 is slidably connected to the inner wall of the cleaning tank 11, a top cover 14 is provided on the top of the cleaning tank 11, and a drying component 15 is fixed to the inner wall of the cleaning tank 11.

[0036] Specifically, auxiliary component 2 includes a locking member 21, which is fixed to one side of the top cover 14. An air-driven adjusting member 22 is provided on the outside of the cleaning tank 11, and a valve adjusting member 23 is fixed on the top of the top cover 14.

[0037] Example 2, refer to Figures 2 to 10 This is the second embodiment of the present invention. Based on the previous embodiment, this embodiment focuses on optimizing the linkage between soaking and cleaning of the cleaning tank, the uniformity of spraying, the reliability of locking and fixing, and the accuracy of air-driven valve adjustment. The specific structure is described below.

[0038] Specifically, the soaking component 13 includes a soaking tank 131 that is slidably connected to the inner wall of the cleaning tank 11. A guide rod 132 is fixed to the inner wall of the soaking tank 131, and a limiting cross plate 133 is fixed to the top of the guide rod 132.

[0039] The soaking component 13 achieves the soaking and cleaning of materials. The soaking tank 131 is made of wear-resistant and corrosion-resistant material and slides smoothly along the inner wall of the cleaning tank 11 to adapt to the soaking requirements of different materials. The guide rod 132 provides precise sliding guidance for the soaking tank 131, and the limiting plate 133 limits the maximum sliding stroke of the soaking tank 131 to prevent it from falling off and ensure operational safety. At the same time, it ensures that the soaking tank 131 is accurately positioned when it slides to the designated position.

[0040] Specifically, the top cover 14 includes a top cover body 141 disposed on the top of the cleaning tank 11, a connecting vertical pipe 144 fixed to the bottom of the top cover body 141, and a spray plate 145 fixed to the bottom of the connecting vertical pipe 144.

[0041] The top cover 14 enables spray cleaning. The top cover body 141 is sealed to the top of the cleaning tank 11 to ensure no liquid splashing during spraying. The connecting vertical pipe 144 rigidly connects the top cover body 141 to the spray plate 145. The spray nozzles of the spray plate 145 are evenly distributed, which can achieve all-round spraying and improve the uniformity of cleaning.

[0042] Specifically, a sliding rod 142 is fixed to the bottom of the top cover body 141, and a drive piston 143 is fixed to the bottom of the sliding rod 142. The drying component 15 includes an air jet plate 152 embedded in the inner wall of the cleaning box 11, and an air inlet pipe 151 is fixed to one side of the air jet plate 152.

[0043] The sliding rod 142 provides precise guidance for the drive piston 143, and it is fixedly connected to the top cover body 141 to ensure that the piston moves without deviation; the drive piston 143 cooperates with the air storage chamber 225 of the pneumatic adjustment component 22 to realize the basis of power drive.

[0044] Specifically, the locking member 21 includes a first fixing plate 211 fixed to the top of the sliding rod 142, a second fixing plate 212 fixed to one side of the first fixing plate 211, a movable frame 214 fixed to one side of the second fixing plate 212, and a fixed frame 213 slidably connected to the surface of the movable frame 214.

[0045] The locking component 21 enables quick positioning of the metal wire mesh that needs to be cleaned. The first fixing plate 211 and the second fixing plate 212 enhance the installation stability of the movable frame 214. The movable frame 214 and the fixed frame 213 slide together, providing flexible adjustment space for the locking action.

[0046] Specifically, a fixing rod 215 is fixed to the top of the movable frame 214, the fixing frame 213 is slidably connected to the surface of the fixing rod 215, a locking spring 216 is sleeved on the surface of the fixing rod 215, an irregularly shaped connecting block 219 is fixed to the surface of the movable frame 214, a connecting seat 218 is sleeved on the surface of the irregularly shaped connecting block 219, and a sliding ring 217 that cooperates with the guide rod 132 is fixed to one side of the connecting seat 218.

[0047] The locking spring 216 provides elastic preload to the fixed frame 213, which pushes the fixed frame 213 to maintain the locked state under normal conditions; the sliding ring 217 is precisely matched with the guide rod 132 to achieve precise positioning of the locking structure, ensuring stable connection between the top cover 14 and the cleaning box 11 and preventing shaking. Both the movable frame 214 and the fixed frame 213 have one side with an arc surface, so the movable frame 214 can be pushed open by directly pushing the wire mesh, thus completing the quick installation of the wire mesh.

[0048] Specifically, the pneumatic adjustment component 22 includes a connecting pipe 221 fixed to the outside of the cleaning tank 11, a first flexible hose 222 fixed to the bottom of the connecting pipe 221, an air storage chamber 225 that cooperates with the drive piston 143 opened on the top of the cleaning tank 11, a two-way pressure valve 224 fixed to one side of the connecting pipe 221, a manual valve 223 fixed to the surface of the connecting pipe 221, and the first flexible hose 222 fixed to one side of the air storage chamber 225.

[0049] The pneumatic adjustment component 22 drives the top cover component 14 to move by air pressure. The air storage chamber 225 stores gas to provide power for the driving piston 143. The two-way pressure valve 224 controls the input and output of gas to ensure stable air pressure. The manual valve 223 adjusts the gas flow rate to adapt to different spray pressure requirements and improves the driving accuracy.

[0050] Specifically, the valve regulating component 23 includes a three-way pipe 231 fixed to the top of the top cover body 141, a three-way valve 233 sleeved on the surface of the three-way pipe 231, a valve stem 235 fixed on one side of the three-way valve 233, a transmission gear 234 sleeved on the surface of the valve stem 235, and a transmission gear frame 236 sleeved on the surface of the transmission gear 234.

[0051] One end of the three-way pipe 231 is connected to the flushing fluid, and the other end is connected to the oleophobic coating. The valve regulating component 23 adjusts the connection direction. The three-way valve 233 can switch the fluid path by rotating the valve stem 235 to adapt to different cleaning conditions. The transmission gear 234 meshes with the transmission gear frame 236 to achieve precise power transmission and ensure the stability of valve adjustment.

[0052] Specifically, the valve regulating component 23 also includes a fixing pipe 239 fixed to the top of the top cover body 141, and a second flexible hose 237 fixed to one side of the fixing pipe 239. The second flexible hose 237 is fixed to the top of the connecting pipe 221.

[0053] The second hose 237 connects the fixed pipe 239 and the connecting pipe 221 to realize the linkage adjustment of the air circuit and the liquid circuit, ensuring that the air pressure output of the air-driven regulating component 22 and the flow regulation of the valve regulating component 23 are precisely matched, thereby improving the overall cleaning efficiency.

[0054] Example 3, referring to Figures 2 to 10 This is the third embodiment of the present invention, which is based on the first two embodiments.

[0055] Specifically, a transmission piston 232 is slidably connected to the inner wall of the fixed tube 239, and a transmission rod 238 is fixed to one side of the transmission piston 232. The transmission rod 238 is fixed to one side of the transmission gear frame 236.

[0056] In use, before use, in the initial state, the cleaning tank 11 of the cleaning assembly 1 is placed securely, the movable door 12 on one side is closed, the soaking tank 131 of the soaking component 13 on the inner wall is located at the bottom of the cleaning tank 11, the guide rod 132 is vertically fixed, the limiting horizontal plate 133 limits the maximum sliding stroke of the soaking tank 131, the top cover body 141 of the top cover 14 is at the highest point, the sliding rod 142 drives the drive piston 143 to be at the top of the air storage chamber 225, and the first fixing plate 211 of the locking component 21 is fixed to the second fixing plate 212. With the movable frame 214 and the fixed frame 213 locked, the air storage chamber 225 of the pneumatic adjustment component 22 stores gas, the two-way pressure valve 224 is closed, the manual valve 223 is closed, the first hose 222 is connected to the air storage chamber 225, the three-way pipe 231 of the valve adjustment component 23 is connected to the three-way valve 233, the transmission gear 234 meshes with the transmission gear frame 236, the transmission piston 232 is located at the bottom of the fixed pipe 239, the transmission rod 238 is not connected to the transmission gear frame 236, and the second hose 237 is connected to the connecting pipe 221.

[0057] During cleaning, the worker pushes the metal mesh to be cleaned into the opposite side of the movable frame 214 and fixed frame 213 of the locking component 21. The movable frame 214 is pushed open, the locking spring 216 is compressed and accumulates elastic potential energy, the metal mesh is limited, and the sliding ring 217 slides along the guide rod 132 to ensure precise positioning of the locking structure. Then, the top cover body 141 is pressed down, and the sliding rod 142 drives the drive piston 143 to move downward, compressing the gas inside the gas storage chamber 225. The gas is then transported through the connecting pipe 221. The fluid is fed into the second hose 237 and enters the fixed pipe 239. The drive piston 232 slides along the inner wall of the fixed pipe 239. The drive piston 232 drives the drive rod 238 to move. The drive rod 238 drives the drive gear frame 236 to rotate. The drive gear frame 236 meshes with the drive gear 234, which drives the valve stem 235 to rotate. The three-way valve 233 switches the fluid path. The flushing fluid is delivered to the spray plate 145 through the three-way pipe 231 and the connecting vertical pipe 144. The nozzles of the spray plate 145 spray out the flushing fluid to perform a powerful vertical flushing of the metal wire mesh.

[0058] During the rinsing process, the top cover body 141 continues to drive the locking part 21 to descend, and the movable frame 214 and the fixed frame 213 fall into the inner cavity of the soaking tank 131 until the soaking tank 131 is filled with rinsing liquid to remove floating oil. At this time, the driving piston 143 continuously squeezes the gas in the gas storage chamber 225, and the excess gas is discharged through the two-way pressure valve 224. It will not drive the three-way valve 233 to switch, and the rinsing continues to maintain, ensuring that stubborn oily contaminants are decomposed.

[0059] After soaking, if the wire mesh is to be removed directly for cleaning, the operator pulls up the top cover body 141. When it moves to the point where the three-way valve 233 is closed, the operator rotates to open the manual valve 223, so that the connecting pipe 221 is connected to the outside gas. Continuing to move it up will not cause any additional drive to the three-way valve 233. After the top cover body 141 is removed from the soaking tank 131, the operator can dry the wire mesh through the drying component 15 by starting an external hot air source. If an oleophobic coating needs to be applied after drying, the operator manually rotates to close the manual valve 223. At this time, the operator continues to move the top cover body 141 up, and the air-driven regulating component 22 drives the valve regulating component 23 to move in the opposite direction. The valve stem 235 is rotated in the opposite direction, and the three-way valve 233 switches to the oleophobic coating path. The oleophobic coating is delivered to the spray plate 145 through the three-way pipe 231 and the connecting vertical pipe 144 to apply the oleophobic coating to the wire mesh.

[0060] When the top cover body 141 is pulled to the highest point, the movable frame 214 pulls the limiting horizontal plate 133 upward through the sliding ring 217. The limiting horizontal plate 133 drives the guide rod 132 and the soaking tank 131 to move upward synchronously. Then, the staff opens the movable door 12 and can pull out the soaking tank 131 for cleaning, thus completing the cleaning process.

[0061] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
