Description

Technical Field

[0001] The invention relates to an oil remover, in particular to a stable activated carbon oil remover. Background Art

[0002] Activated carbon deoilers are widely used in new energy, chemical, pharmaceutical, food processing and other industries. Their main purpose is to remove oily substances and other impurities in the gas to achieve the effect of purification. In industrial production, especially in areas requiring high-purity raw materials or products, activated carbon deoilers play an important role. They can effectively adsorb and fix oily substances and other pollutants to ensure that the treated gas meets the requirements of subsequent processes or uses. In addition, activated carbon deoilers can also help extend the service life of related equipment, reduce maintenance costs and improve production efficiency.

[0003] During long-term use of traditional activated carbon degreasers, the activated carbon in them will be affected by factors such as mechanical vibration and airflow impact, causing the activated carbon layer to loosen or be damaged, thereby affecting the degreasing effect and stability. Some existing activated carbon degreasers will fill the activated carbon into certain regular tooling to improve the stability of the activated carbon during use, thereby improving the stability of the activated carbon. However, this method is likely to limit the loading and unloading of the activated carbon, which is inconvenient both when using and replacing, and each time it is reinstalled, it is necessary to reconsider whether the distribution and setting of the activated carbon are within a reasonable range.

[0004] Therefore, this case aims to provide a stable activated carbon deoiler, which can not only absorb impurities such as suspended particles and organic matter in the air to further improve the quality of the gas, but also has efficient adsorption capacity and a long service life, which can reduce the frequency of replacing the adsorbent and reduce maintenance costs. Summary of the invention

[0005] The present invention provides a stable activated carbon deoiler, which can effectively solve the above problems.

[0006] The present invention is achieved in that: A stable activated carbon degreasing device comprises an oil removal tank, a matching plate is arranged on the top surface of the oil removal tank, a tank cover is arranged on the top of the oil removal tank, the outer side of the tank cover is matched with the matching plate through a locking plate, an air outlet pipe is arranged on the top of the tank cover, an air inlet pipe is connected to the bottom of the outer side of the oil removal tank, the oil removal tank is filled with activated carbon, and the activated carbon degreasing device also comprises: The activated carbon compression structure comprises a lower compression assembly arranged at the bottom of the de-oiling tank, an upper compression assembly is arranged inside the tank cover, and an oblique pipe is arranged at the lower end of the outer side of the de-oiling tank. The de-oiling tank is filled with the activated carbon. When the tank cover is locked with the de-oiling tank, the activated carbon is compressed between the upper compression assembly and the lower compression assembly. After the activated carbon is used for a fixed time, the activated carbon is discharged through the oblique pipe. The inner top plate decontamination structure comprises a heating element arranged inside the upper pressing assembly, the heating element passes through the upper pressing assembly through an external conduit and communicates with an external circuit, and when the upper pressing assembly presses the activated carbon downward, the heating element is closely attached to the bottom of the inner side of the upper pressing assembly; The segmented arrangement structure is characterized in that the activated carbon is divided into large-particle activated carbon and small-particle activated carbon. The segmented arrangement structure comprises a containing fixture arranged in the oil removal tank. The containing fixture is divided into an upper and lower part by a divider. The large-particle activated carbon is filled in the lower half of the containing fixture, and the small-particle activated carbon is contained in the upper half of the containing fixture. When the activated carbon is discharged, the large-particle activated carbon is discharged through the oblique pipe. When the divider is actuated, the small-particle activated carbon is discharged into the lower half of the containing fixture.

[0007] As a further improvement, the upper clamping assembly includes an upper pressure plate welded to the outer side wall of the outlet pipe, and an exhaust chamber is bolted to the position corresponding to the air inlet of the outlet pipe below the upper pressure plate. A plurality of springs are also arranged below the upper pressure plate, and a spring clamping plate is connected to the bottom of the plurality of springs. A plurality of passing areas are provided on the spring clamping plate, and the spring clamping plate is clamped on the upper end of the activated carbon. After being filtered by the activated carbon, the gas will pass through the passing area and then be discharged from the outlet pipe from the area of ​​the exhaust chamber.

[0008] As a further improvement, the exhaust chamber includes a stainless steel mesh connected to the lower end of the upper pressure plate, the stainless steel mesh is connected to a through cavity, and the gas enters through the stainless steel mesh and flows into the exhaust pipe through the through cavity.

[0009] As a further improvement, the lower clamping assembly includes a lower pressure plate arranged in the inner wall of the oil removal tank, and a screen is connected below the lower pressure plate. The lower pressure plate supports large-particle activated carbon, and the oil filtered by the large-particle activated carbon will drip through the screen to the bottom of the oil removal tank.

[0010] As a further improvement, a drain pipe is connected to the bottom of the oil removal tank, and the drain pipe is connected to an external negative pressure suction structure.

[0011] As a further improvement, the heating element includes a heater fixedly connected to the bottom of the exhaust chamber, and a heating plate is connected to the lower end of the heater. After the spring pressure plate is squeezed upward by the activated carbon, the heating plate is tightly attached to the top of the spring pressure plate.

[0012] As a further improvement, the divider is arranged in the middle position of the accommodating tooling, and the divider includes a rotating part arranged on the outer wall of the oil removal tank. A partition mesh plate is connected to the output end of the rotating part, and the diameter of the holes on the partition mesh plate is smaller than the particle diameter of the small-particle activated carbon.

[0013] As a further improvement, it also includes a lower adjustment structure, the lower pressure plate, the screen are movably connected to the inner wall of the oil removal tank, the side walls of the lower pressure plate and the screen are open, the lower adjustment structure includes a plurality of pushing members connected under the screen, and a positioning member is opened on the outer side wall of the oil removal tank. When the lower pressure plate and the screen are moved to the correct position, the positioning member is locked on the opening of the side wall of the lower pressure plate and the screen.

[0014] As a further improvement, the alignment member includes a matching tube embedded in the outer wall of the oil removal tank, a docking pin is threaded in the matching tube, and the docking pin passes through the matching tube and is connected to the openings of the lower pressure plate and the side wall of the screen.

[0015] The beneficial effects of the present invention are: In the existing oil removers, fixed tooling is mostly used to fix the installation of activated carbon. Not only is the installation and setting of the tooling complicated, but the loading and unloading of the activated carbon is also difficult and very labor-intensive. Not only is the activated carbon in the oil remover unstable, but the oil removal efficiency still needs to be considered. Therefore, the present invention uses an additional activated carbon compression structure to standardize the activated carbon in a fixed space through the lower compression component and the upper compression component, thereby forming a stable activated carbon filter layer. When the pressurized gas passes through the activated carbon area, the activated carbon can deeply remove oily substances in the compressed air. The porous structure of the activated carbon gives it a large specific surface area, which can effectively adsorb and fix oily substances and reduce the oil content in the compressed air. At the same time, since the activity of the activated carbon is limited, it can be relatively stable. While the oil removal effect is guaranteed, the overall oil removal process is very stable.

[0016] During the clamping process of the upper clamping assembly, it not only needs to compress the activated carbon, but also needs to allow the gas to be smoothly discharged to the position of the outlet pipe. Therefore, the upper clamping assembly of the present invention is not only provided with a spring and a spring clamping plate for the clamping function, but also a passing area is opened on the spring clamping plate, and an exhaust chamber is set at the position of the upper clamping plate to allow the gas to have circulation conditions, thereby forming an effect of discharging high-quality gas under the filtration of stable activated carbon.

[0017] The through cavity in the entire exhaust chamber is hollow, so that the gas can be discharged easily. Before entering the through cavity, it needs to be filtered through a stainless steel mesh to avoid particles from settling in the through cavity. The setting of the stainless steel mesh can also greatly reduce the precipitation that may be formed in the through cavity, thereby improving the exhaust quality.

[0018] During the compaction process of the lower compaction component, a supporting method is adopted. The activated carbon is initially laid in this area, and an activated carbon layer is formed after layer-by-layer stacking. Therefore, all oily substances and dirt will also be concentrated in this area. In order to avoid blockage of the sewage pipe, a screen is also required to be set in the lower compaction component to form an inner support and outer filtering and screening effect.

[0019] Although the activated carbon is bound by the lower clamping assembly and the upper clamping assembly, it also brings a problem. That is, the upward oily components will partially adhere to the lower end of the upper clamping assembly, thereby forming an oily layer that is difficult to clean. The newly introduced air will always be disturbed by the oily layer, and the overall oil removal effect is affected. Therefore, the present invention provides an inner top plate decontamination structure in the upper clamping assembly on the basis of the lower clamping assembly and the upper clamping assembly. The contact position of the upper clamping assembly and the activated carbon can be heated by a heating element, thereby continuously keeping the area of ​​the upper clamping assembly where the oily substance may adhere to a state of constant heating. The oily substance cannot solidify and can only be continuously discharged downward, so that the compressed air will not be repeatedly contaminated when passing through the coverage area of ​​the upper clamping assembly.

[0020] During heating, since the upper clamping assembly is provided with a spring and a spring clamping plate, the internal space of the entire upper clamping assembly will be compressed. Therefore, the setting of the inner top plate decontamination structure cannot be set to be completely fitted at the beginning, but will be completely fitted to the heating plate only after the spring clamping plate is clamped. The spring clamping plate is heated by the heating of the heating plate, so that the side of the spring clamping plate close to the activated carbon is not easy to accumulate oil stains, thereby greatly improving the practical effect of the present invention.

[0021] In the setting of conventional oil removers, activated carbons are all of uniform specifications. Although they can also play the role of filtering and separation, in fact, the load of activated carbon at the lower end is greater than that at the upper end. Therefore, the present invention sets a segmented arrangement structure on the inner side of the oil removal tank, and divides the area containing activated carbon in the entire oil removal tank into two parts through a containing tool and a divider, and fills two types of activated carbons with different diameters. Large-particle activated carbon is set at the lower end, which can achieve better adsorption effect and better discharge in the sewage discharge stage, while small-particle activated carbon is set in the top area, with a denser arrangement density and a larger arrangement quantity, thereby achieving a high-precision full coverage effect.

[0022] When discharging, the large particles below will be discharged first, and the small particles of activated carbon will be discharged after the lower part is discharged. After the lower end is discharged, you only need to rotate the rotating parts in the separator to create a gap between the partition mesh plate and the inner wall of the oil removal tank, so that the upper material can be discharged downward, and the material can be discharged in grades, and the activated carbon with different usage functions can be separated, and graded regeneration treatment can be carried out after recovery.

[0023] When laying the materials, in order to fully achieve the stability between the activated carbons and improve the practical effect of the present invention, the present invention also sets a lower adjustment structure in the area of ​​the oil removal tank corresponding to the lower pressure plate. Through the pushing member and the positioning member set in the lower adjustment structure, the lower pressure plate can reach the accurate area, so that the gaps between the activated carbons are fully filled, and the filtering surface is more comprehensively stable. In addition, the overall weight after adjustment is not only borne by the pushing member, but also shared by the laterally fixed positioning members, so that the bearing pressure of the lower pressure plate is more stable.

In the description of the present invention, the meaning of "multiple" is two or more, unless otherwise clearly and specifically defined.

[0035] Reference Figure 1 to Figure 7As shown, a stable activated carbon deoiler comprises an oil removal tank 10, the top surface of the oil removal tank 10 is provided with a matching plate 11, the top of the oil removal tank 10 is provided with a tank cover 20, the outer side of the tank cover 20 is matched with the matching plate 11 through a locking plate 21, the top of the tank cover 20 is provided with an air outlet pipe 22, the bottom of the outer side of the oil removal tank 10 is connected with an air inlet pipe 12, the oil removal tank 10 is filled with activated carbon, the activated carbon deoiler also includes: an activated carbon pressing structure 30, comprising a lower pressing component 31 arranged at the bottom of the oil removal tank 10, an upper pressing component 32 is arranged inside the tank cover 20, and an oblique pipe 33 is arranged at the lower end of the outer side of the oil removal tank 10, the activated carbon is filled in the oil removal tank 10, when the tank cover 20 is locked and matched with the oil removal tank 10, the activated carbon is pressed between the upper pressing component 32 and the lower pressing component 31, after the activated carbon is used for a fixed time, through the The oblique pipe 33 discharges the activated carbon; the inner top plate decontamination structure includes a heating element 41 arranged inside the upper clamping component 32, and the heating element 41 passes through the upper clamping component 32 through an external guide tube to communicate with the external circuit. When the upper clamping component 32 presses the activated carbon downward, the heating element 41 is tightly attached to the bottom of the inner side of the upper clamping component 32; a segmented arrangement structure 50, the activated carbon is divided into large-particle activated carbon and small-particle activated carbon, and the segmented arrangement structure 50 includes a containing tool 51 arranged in the oil removal tank 10, and the containing tool 51 is divided into an upper and lower part by a divider 52. The large-particle activated carbon is filled in the lower half of the containing tool 51, and the small-particle activated carbon is contained in the upper half of the containing tool 51. When the activated carbon is discharged, the large-particle activated carbon is discharged through the oblique pipe 33, and when the divider 52 is actuated, the small-particle activated carbon is discharged into the lower half of the containing tool 51.

[0036] In the process of degreasing with activated carbon, it is necessary to first arrange the activated carbon. First, open the tank cover 20, and put large particles of activated carbon into the lower part of the containing tooling 51. After the lower half area is completely covered, adjust the divider 52, and then put small particles of activated carbon. Finally, cover the tank cover 20 to achieve a limited seal between the two areas.

[0037] The compressed gas (which may be air) is introduced through the air inlet pipe 12 , and is discharged from the air outlet pipe 22 after passing through the lower pressing plate 311 , the activated carbon layer and the upper pressing assembly 32 .

[0038] In the existing oil removers, fixed tooling is mostly used to fix the installation of activated carbon. Not only is the installation and setting of the tooling cumbersome, but the loading and unloading of the activated carbon is also relatively difficult and very labor-intensive. Not only is the activated carbon in the oil remover unstable, but the oil removal efficiency still needs to be considered. Therefore, the present invention uses an additional activated carbon pressing structure 30 to regulate the activated carbon in a fixed space through the lower pressing component 31 and the upper pressing component 32, thereby forming a stable activated carbon filter layer. When the pressurized gas passes through the activated carbon area, the activated carbon can deeply remove oily substances in the compressed air. The porous structure of the activated carbon gives it a large specific surface area, which can effectively adsorb and fix oily substances and reduce the oil content in the compressed air. At the same time, since the activity of the activated carbon is limited, it can be relatively stable. While the oil removal effect is guaranteed, the overall oil removal process is very stable.

[0039] During the compression process of the upper compression component 32, it not only needs to play the role of compressing the activated carbon, but also needs to allow the gas to be smoothly discharged to the position of the outlet pipe 22. Therefore, the upper compression component 32 of this embodiment includes an upper compression plate 321 welded to the outer wall of the outlet pipe 22, and an exhaust chamber 322 is bolted to the position corresponding to the air inlet of the outlet pipe 22 below the upper compression plate 321. A plurality of springs 323 are also provided below the upper compression plate 321, and the bottoms of the plurality of springs 323 are connected to spring compression plates 324, and the spring compression plates 324 have openings. A plurality of passing areas 325 are provided, and the spring clamping plate 324 is pressed on the upper end of the activated carbon, and the gas will be discharged from the exhaust chamber 322 through the passing area 325 after being filtered by the activated carbon and discharged from the exhaust pipe 22. The upper clamping component 32 is not only provided with a spring 323 and a spring clamping plate 324 for the clamping function, but also a passing area 325 is opened on the spring clamping plate 324, and an exhaust chamber 322 is set at the position of the upper pressure plate 321, so that the gas can have circulation conditions, thereby forming an effect of discharging high-quality gas under the filtration of stable activated carbon.

[0040] The through cavity 3222 in the entire exhaust chamber 322 is a hollow setting. Specifically, the exhaust chamber 322 includes a stainless steel mesh 3221 connected to the lower end of the upper pressure plate 321, and the stainless steel mesh 3221 is connected to a through cavity 3222. After the gas enters through the stainless steel mesh 3221, it flows into the exhaust pipe 22 through the through cavity 3222, so that the gas can be discharged easily. Before entering the through cavity 3222, it needs to be finally filtered through the stainless steel mesh 3221 to avoid particles from being deposited in the through cavity 3222. The setting of the stainless steel mesh 3221 can also greatly reduce the precipitation phenomenon that may be formed in the through cavity 3222, thereby improving the exhaust quality.

[0041] Furthermore, a sewage pipe 70 is connected to the bottom of the oil removal tank 10, and the sewage pipe 70 is connected to an external negative pressure suction structure.

[0042] During the compacting process of the lower compacting component 31, a supporting method is adopted. The activated carbon is initially arranged in this area, and an activated carbon layer is formed after being stacked layer by layer. Therefore, all oily substances and dirt will also be concentrated in this area. In order to avoid clogging of the sewage pipe 70, the lower compacting component 31 of this embodiment includes a lower pressure plate 311 arranged in the inner wall of the oil removal tank 10, and a screen 312 is connected below the lower pressure plate 311. The lower pressure plate 311 supports large-particle activated carbon. The oil filtered by the large-particle activated carbon will drip through the screen to the bottom of the oil removal tank 10. By arranging the screen 312 in the lower compacting component 31, the inner side of the lower pressure plate 311 is supported, and the outer side of the screen 312 is filtered and screened.

[0043] Although the activated carbon is bound by the lower clamping component 31 and the upper clamping component 32, it also brings a problem. That is, the upward oily components will partially adhere to the lower end of the upper clamping component 32, thereby forming an oily layer that is difficult to clean. The newly introduced air will always be disturbed by the oily layer, and the overall oil removal effect is affected. Therefore, the present invention provides an inner top plate decontamination structure in the upper clamping component 32 on the basis of the lower clamping component 31 and the upper clamping component 32, and can heat the position where the upper clamping component 32 and the activated carbon are in contact through the heating element 41, so that the area of ​​the upper clamping component 32 where the oily substance may adhere is constantly heated. The oily substance cannot solidify and can only be continuously discharged downward, so that the compressed air will not be repeatedly contaminated when passing through the coverage area of ​​the upper clamping component 32.

[0044] During heating, since the upper clamping assembly 32 is provided with a spring 323 and a spring clamping plate 324, the internal space of the entire upper clamping assembly 32 will be compressed. Therefore, the heating element 41 includes a heater 411 fixedly connected to the bottom of the exhaust chamber 322, and the lower end of the heater 411 is connected to a heating plate 412. After the spring clamping plate 324 is squeezed upward by the activated carbon, the heating plate 412 is tightly attached to the top of the spring clamping plate 324. The setting of the inner top plate decontamination structure cannot be set to be completely fitted at the beginning, but will be completely fitted to the heating plate 412 only after the spring clamping plate 324 is clamped. The spring clamping plate 324 is heated by the heating of the heating plate 412, so that the side of the spring clamping plate 324 close to the activated carbon is not easy to accumulate oil stains, thereby greatly improving the practical effect of the present invention.

[0045] In the setting of conventional oil removers, activated carbons are all of uniform specifications. Although they can also play the role of filtering and separation, in fact, the load of activated carbon at the lower end is greater than that at the upper end. Therefore, the present invention sets a segmented arrangement structure 50 on the inner side of the oil removal tank 10, and divides the area containing activated carbon in the entire oil removal tank 10 into two parts through a containing tool 51 and a divider 52, and fills two types of activated carbons with different diameters. Large-particle activated carbon is set at the lower end, which can achieve better adsorption effect and better discharge in the sewage discharge stage, while small-particle activated carbon is set in the top area, with a denser arrangement density and a larger arrangement quantity, thereby achieving a high-precision full coverage effect.

[0046] Specifically, the divider 52 is arranged in the middle position of the accommodating tooling 51, and the divider 52 includes a rotating member 521 arranged on the outer wall of the oil removal tank 10. A partition mesh plate 522 is connected to the output end of the rotating member 521. The diameter of the holes on the partition mesh plate 522 is smaller than the particle diameter of the small-particle activated carbon. When discharging, the large particles below will be discharged first, and the small-particle activated carbon will be discharged after the lower part is discharged. After the lower end is discharged, it is only necessary to rotate the rotating member 521 in the divider 52 to allow a gap to exist between the partition mesh plate 522 and the inner wall of the oil removal tank 10, so that the upper layer of material can be discharged downward, and the material can be discharged in stages, and the activated carbon with different usage functions can be separated, and graded regeneration treatment can be performed after recovery.

[0047] During the distribution, in order to fully realize the stability between the activated carbons and improve the practical effect of the present invention, the present invention further sets a lower adjustment structure 60 in the area of ​​the deoiling tank 10 corresponding to the lower pressure plate 311, and the lower pressure plate 311 and the screen 312 are movably connected to the inner wall of the deoiling tank 10, and the side walls of the lower pressure plate 311 and the screen 312 are open, and the lower adjustment structure 60 includes a plurality of pushers 61 connected to the bottom of the screen 312, and a positioning member 62 is provided on the outer side wall of the deoiling tank 10. When the lower pressure plate 31 1. When the screen 312 moves to the accurate position, the alignment member 62 is locked on the openings of the lower pressure plate 311 and the side walls of the screen 312. The pushing member 61 and the alignment member 62 arranged in the lower adjustment structure 60 can enable the lower pressure plate 311 to reach the accurate area, so that the gaps between the activated carbons are fully filled, and the filtering surface is more comprehensively stable. In addition, the overall weight after adjustment is not only borne by the pushing member 61, but also shared by the laterally fixed alignment member 62, so that the bearing pressure of the lower pressure plate 311 is more stable.

[0048] Specifically, the alignment member 62 includes a matching tube 621 embedded on the outer wall of the oil removal tank 10, and a docking pin 622 is screwed in the matching tube 621. The docking pin 622 passes through the matching tube 621 and is connected to the openings of the side walls of the lower pressure plate 311 and the screen 312.

For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
