Abstract
Description
Technical Field
[0001] This utility model relates to the field of gas filtration technology, and more specifically, to a composite activated carbon fiber oil and gas adsorption core structure. Background Technology
[0002] Common activated carbon adsorption filter cartridges have activated carbon sections that are compacted, preventing them from forming a three-dimensional spatial structure. This results in low flow rates, high pressure losses, and even clogging during filtration. Additionally, some activated carbon particles fail to provide effective filtration, impacting adsorption efficiency. Therefore, it is necessary to optimize the structure of the adsorption cartridge to improve adsorption performance and effectiveness.
[0003] A search revealed that Chinese patent CN222829275U discloses a "Gas Impurity Filtering Device," which addresses the problem of poor sealing performance in existing gas filtering devices, allowing air impurities to easily enter the tank during filtration and compromising filtration effectiveness. The device includes a base providing installation space; a filter cylinder mounted on the base with an internal filtration chamber and an opening at one end communicating with the filtration chamber; an inlet and an outlet also communicating with the filtration chamber; a sealing unit positioned over the opening to raise the filter cylinder; and a filtering unit within the filtration chamber to filter impurities from the gas. This invention features a sealing unit design, including a sealing cover and a sealing gasket, effectively preventing external impurities from entering the filtration chamber during filtration, ensuring stable and reliable filtration. However, it still has the following drawbacks:
[0004] (1) When the above application is used, after long-term use, the pores of activated carbon are filled with pollutants and can no longer adsorb particles, harmful gases, etc. If it is not cleaned in time, it may even lead to the reverse release of pollutants.
[0005] When the above-mentioned applications are in use, larger particles in the oil and gas cannot be discharged in time and will accumulate in pipes and valves. The inability to discharge them automatically in time will cause grease to clog the channels. To address this, a composite activated carbon fiber oil and gas adsorption core structure is proposed. Utility Model Content
[0006] The purpose of this invention is to address the problem that after long-term use, the pores of the activated carbon in the filter element become filled with pollutants, making it unable to adsorb particles and harmful gases, thus causing blockage.
[0007] To achieve the above-mentioned objectives, this utility model provides the following technical solution:
[0008] The present invention is as follows: a composite activated carbon fiber oil and gas adsorption core structure includes a placement base, a tank fixedly installed on the inner wall of the placement base, an air inlet on the left side of the tank, an air outlet on the right side of the tank, a fixed end of a servo motor at the top of the tank, a drive rod fixedly installed at the output end of the servo motor, a filter element sleeved on the circumferential surface of the drive rod, and a filtration mechanism inside the tank; the filtration mechanism includes a connecting seat sleeved on the circumferential surface of the drive rod, a guide plate fixedly installed on the surface of the connecting seat, a round rod fixedly installed at the bottom of the drive rod, a reciprocating spiral groove on the circumferential surface of the round rod, a sliding seat threaded on the circumferential surface of the round rod, an adsorption plate fixedly installed on the surface of the sliding seat, a hinge seat on the inner wall of the tank, a toggle plate rotatably installed on the inner wall of the hinge seat, and a spring piece between the toggle plate and the tank; the above structure achieves a self-cleaning effect for the filter element.
[0009] As a preferred technical solution of this utility model, the filter element is provided with an activated carbon layer inside, a transfer seat is provided at the bottom of the filter element, and the number of guide plates is set to several and arranged in a circular array along the center of the tank. The oil and gas are allowed to move downward through the guide plates and then diffuse around the circumference of the filter element.
[0010] As a preferred technical solution of this utility model, the adsorption plate is in contact with the inner wall of the filter element, and an activated carbon layer is provided inside the adsorption plate. When the sliding seat moves, it drives the adsorption plate to move, so that the adsorption plate comes into contact with the inner wall of the filter element.
[0011] As a preferred technical solution of this utility model, the number of the hinge seat, the actuating plate and the spring sheet is set to three, and they are arranged in a circular array along the center of the tank. After the adsorption plate disengages from the contact with the actuating plate, the spring sheet drives the actuating plate to reset. The reset of the actuating plate makes contact with the transmission seat at the bottom of the filter element, thereby generating oscillation.
[0012] As a preferred technical solution of this utility model, the bottom of the round rod is provided with an oil removal mechanism. The oil removal mechanism includes a drive seat, which is fixedly installed at the bottom of the round rod. An oil suction plate is fixedly installed on the surface of the drive seat near the inner wall of the tank. When the drive seat rotates, it drives the oil suction plate to rotate. The rotation of the oil suction plate causes the sponge to absorb the attached impurities.
[0013] As a preferred technical solution of this utility model, the surface of the oil-absorbing plate near the inner wall of the tank is provided with a sponge, and the number of oil-absorbing plates is set to three, which are arranged in a circular array along the center of the tank to reduce adsorption dead angles and reduce the amount of oil residue.
[0014] As a preferred technical solution of this utility model, a reciprocating screw is fixedly installed at the bottom of the drive seat, an oil outlet is provided at the bottom of the tank, and a sealing plug is installed on the circumferential thread of the reciprocating screw. When the sealing plug moves upward, it will gradually open the oil outlet, allowing some of the cleaned grease to be discharged.
[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0016] 1. Through the designed filtration mechanism, under long-term use, the adsorption capacity of activated carbon filter cartridges has an upper limit. After long-term use, the pores of activated carbon become filled with pollutants, making it unable to adsorb odors, harmful gases, etc., and may even lead to the reverse release of pollutants. At this time, the adsorption plate contacts and adheres to the inner wall of the filter cartridge, using the oleophilicity and adsorption properties of activated carbon to adhere these residual impurities, reducing the accumulation of pollutants on the surface of the filter cartridge and slowing down the rate of filter cartridge reclogging. By resetting the toggle plate, it contacts the transfer seat at the bottom of the filter cartridge, causing vibration. The vibration is then transmitted to the inside of the filter cartridge through the transfer seat. For some fine particles embedded in the pores of the filter cartridge, the resonance effect can shake them out of the pores, reducing pore blockage and restoring the filtration area and throughput of the filter cartridge to a certain extent.
[0017] 2. Through the set oil removal mechanism, large particles located at the bottom of the tank will gradually accumulate on the inner wall of the tank. At this time, the sponge absorbs the attached impurities. Compared with rigid adsorption materials, the sponge can fit more closely to the irregular inner wall of the tank, such as the arc and corner, reducing adsorption dead areas and reducing the amount of grease residue. The reciprocating screw rotates to make the sealing plug move up and down. When the sealing plug moves upward, it will gradually open the oil outlet, allowing some of the cleaned grease to be discharged. Intermittent automatic discharge does not require interruption of the normal operation of the tank, reducing production downtime caused by cleaning and improving equipment utilization.

[0028] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, this embodiment proposes a composite activated carbon fiber oil and gas adsorption core structure, including a placement base 1, a tank 2 fixedly installed on the inner wall of the placement base 1, an air inlet 3 on the left side of the tank 2, an air outlet 4 on the right side of the tank 2, a fixed end of a servo motor 5 on the top of the tank 2, a drive rod 6 fixedly installed on the output end of the servo motor 5, a filter element 7 sleeved on the circumferential surface of the drive rod 6, and a filtration mechanism 8 inside the tank 2; the filtration mechanism 8 includes a connecting seat 80, which is sleeved on the circumferential surface of the drive rod 6, connecting... A guide plate 81 is fixedly installed on the surface of the receiving seat 80. A round rod 82 is fixedly installed at the bottom of the drive rod 6. A reciprocating spiral groove is opened on the circumferential surface of the round rod 82. A sliding seat 83 is threaded on the circumferential surface of the round rod 82. An adsorption plate 84 is fixedly installed on the surface of the sliding seat 83. A hinge seat 85 is provided on the inner wall of the tank 2. An actuating plate 86 is rotatably installed on the inner wall of the hinge seat 85. A spring piece 87 is provided between the actuating plate 86 and the tank 2. Through the above structure, the filter element 7 can perform intermittent self-cleaning measures, thereby improving the service life of the filter element 7.
[0029] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, in a preferred embodiment, based on the above method, the filter element 7 is further provided with an activated carbon layer inside, a transfer seat is provided at the bottom of the filter element 7, and the number of guide plates 81 is set to several, and they are arranged in a circular array along the center of the tank 2, so as to guide the flow of oil and gas through the guide plates 81.
[0030] like Figure 4 As shown, in a preferred embodiment, based on the above method, the adsorption plate 84 is further in contact with the inner wall of the filter element 7, and an activated carbon layer is provided inside the adsorption plate 84. The adsorption plate 84 utilizes the oleophilicity and adsorption properties of the activated carbon to adhere these residual impurities, thereby reducing the accumulation of pollutants on the surface of the filter element 7.
[0031] like Figure 5 As shown, in a preferred embodiment, based on the above method, the number of hinge seat 85, toggle plate 86 and spring piece 87 is further set to three, and they are arranged in a circular array along the center of the tank 2. Through the resonance effect, they are shaken out of the pores, reducing pore blockage and restoring the filtration area and throughput of the filter element 7 to a certain extent.
[0032] like Figure 3 and Figure 5 As shown, in a preferred embodiment, based on the above method, the bottom of the round rod 82 is further provided with an oil removal mechanism 9. The oil removal mechanism 9 includes a drive seat 90, which is fixedly installed at the bottom of the round rod 82. An oil suction plate 91 is fixedly installed on the surface of the drive seat 90 near the inner wall of the tank 2, so as to absorb the attached impurities.
[0033] like Figure 5 As shown, in a preferred embodiment, based on the above method, a sponge is further provided on the surface of the oil-absorbing plate 91 near the inner wall of the tank 2. Compared with rigid adsorption materials, the sponge can fit more closely to the irregular inner wall of the tank 2, such as the arc and corner, reducing adsorption dead angles and reducing the amount of oil residue. The number of oil-absorbing plates 91 is set to three, and they are arranged in a circular array along the center circumference of the tank 2.
[0034] like Figure 5 As shown, in a preferred embodiment, based on the above method, a reciprocating screw 92 is fixedly installed at the bottom of the drive seat 90, an oil outlet 93 is provided at the bottom of the tank 2, and a sealing plug 94 is installed on the circumferential thread of the reciprocating screw 92, so that some of the cleaned grease can be discharged. The intermittent automatic discharge can eliminate the need to interrupt the normal operation of the tank 2, reduce the production downtime caused by cleaning, and improve the equipment utilization rate.
[0035] Specifically, in use, the composite activated carbon fiber oil and gas adsorption core structure works as follows: oil and gas enter the tank 2 through the inlet 3 and then enter the guide plate 81. The guide plate 81 guides the oil and gas downwards, allowing it to diffuse around the circumference of the filter element 7. Larger particles in the oil and gas are separated to the bottom of the tank 2 by centrifugal force and gravity, while other substances are adsorbed by the filter element 7 and subsequently discharged through the filter element 7 to the outlet 4. However, with long-term use, the adsorption capacity of the activated carbon filter element 7 has an upper limit. After prolonged use, the pores of the activated carbon become filled with pollutants, making it unable to adsorb odors, harmful gases, etc., and may even lead to the reverse release of pollutants. At this point, the servo motor 5 drives the drive rod 6 to rotate, which in turn causes the circular rod 82 to rotate. The rotation of the circular rod 82, with the opening of the reciprocating spiral groove, causes the sliding seat 83 to move up and down reciprocally. As filter element 83 moves, it also moves adsorption plate 84. Adsorption plate 84 contacts the inner wall of filter element 7, and through contact and adhesion, the oleophilic and adsorption properties of activated carbon adhere to these residual impurities, reducing the accumulation of pollutants on the surface of filter element 7 and slowing down the rate at which filter element 7 becomes clogged again. At this time, adsorption plate 84 continues to move downward, eventually contacting actuating plate 86, causing actuating plate 86 to rotate downward. The downward rotation of actuating plate 86 compresses spring 87. After adsorption plate 84 disengages from actuating plate 86, spring 87 drives actuating plate 86 to reset. The reset of actuating plate 86 brings it into contact with the transmission seat at the bottom of filter element 7, causing oscillation. The oscillation is then transmitted to the interior of filter element 7 through the transmission seat. For fine particles partially embedded in the pores of filter element 7, the resonance effect can shake them out of the pores, reducing pore clogging and restoring the filtration area and flow rate of filter element 7 to a certain extent.
[0036] Large particles located at the bottom of the tank 2 will gradually accumulate on the inner wall of the tank 2. At this time, the rotation of the round rod 82 drives the drive seat 90 to rotate, which in turn drives the oil suction plate 91 to rotate. The rotation of the oil suction plate 91 causes the sponge to absorb the attached impurities. Compared with rigid adsorption materials, the sponge can fit more closely to the irregular inner wall of the tank 2, such as the arc and corner, reducing adsorption dead areas and reducing the amount of grease residue. At the same time, the rotation of the drive seat 90 drives the reciprocating screw 92 to rotate. The rotation of the reciprocating screw 92 causes the sealing plug 94 to move up and down. When the sealing plug 94 moves upward, it will gradually open the oil outlet 93, allowing some of the cleaned grease to be discharged. The intermittent automatic discharge does not require interruption of the normal operation of the tank 2, reducing the production downtime caused by cleaning and improving equipment utilization.
[0037] All technical features in this embodiment can be freely combined according to actual needs.
[0038] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
