Description

Technical Field

[0001] The present invention relates to the field of carbon fiber felt recycling, and particularly to a dust cleaning device for recycling activated carbon fiber felt. Background Art

[0002] Activated carbon fiber felt is a felt-like material made of activated carbon fibers. It has a highly developed pore structure and a large specific surface area, and can efficiently adsorb impurities and pollutants in various gases and liquids. Its pore size distribution is uniform, the adsorption speed is fast, and the regeneration performance is good. It can be widely used in the fields of air purification, sewage treatment, solvent recovery, etc., and is an adsorption material with excellent performance.

[0003] During the dust treatment process of activated carbon fiber felt, due to its complex microporous structure inside, dust is likely to hide in it and is difficult to be thoroughly cleaned. This not only reduces the adsorption efficiency of the activated carbon fiber felt, but also may affect its service life. In order to improve the cleaning effect, it is usually necessary to stretch and unfold the activated carbon fiber felt. Stretching and unfolding can generate gaps between the originally closely packed fiber layers, thereby exposing more internal pores and adsorption sites, making it easier to clean the dust. Summary of the Invention

[0004] The purpose of the present invention is to solve the deficiencies existing in the prior art, and to propose a dust cleaning device for recycling activated carbon fiber felt.

[0005] The present invention provides a dust cleaning device for recycling activated carbon fiber felt, including an outer box body, and further including:

[0006] Two openings, respectively penetrating and opened at the top of the outer box body for the activated carbon fiber felt to penetrate and pass through;

[0007] A stretching component, installed inside the outer box body for stretching and expanding the passing activated carbon fiber felt;

[0008] A cleaning component, installed inside the outer box body for cleaning the expanded activated carbon fiber felt;

[0009] A first driving member, installed inside the outer box body for driving the cleaned activated carbon fiber felt to pass out through one of the openings;

[0010] When cleaning the activated carbon fiber felt, the activated carbon fiber felt to be cleaned is inserted from the inside of the opening. After the activated carbon fiber felt is inserted, the stretching assembly first conveys the activated carbon fiber felt into the interior of the outer box until the activated carbon fiber felt is conveyed and guided to the bottom of the stretching assembly. Then, the stretching assembly starts to stretch and expand the activated carbon fiber felt, so that the activated carbon fiber felt is expanded around under the stretching action of the stretching assembly, creating gaps between the originally tightly packed fiber layers, thereby exposing more internal pores and adsorption sites, making it easier to clean out the dust. After the activated carbon fiber felt is stretched and unfolded, the cleaning assembly cleans the unfolded activated carbon fiber felt, thereby improving the cleaning effect of the activated carbon fiber felt;

[0011] After the cleaning of the activated carbon fiber felt is completed, under the driving action of the first driving member, the activated carbon fiber felt is output from the inside of the other opening, thus completing the entire cleaning process of the activated carbon fiber felt;

[0012] The first driving member includes two horizontal driving rollers symmetrically arranged on both sides of the activated carbon fiber felt, and two driving motors for driving the horizontal driving rollers to rotate. After the horizontal driving rollers rotate, they jointly squeeze and convey the activated carbon fiber felt to realize the output driving of the cleaned activated carbon fiber felt.

[0013] Preferably, the stretching assembly includes:

[0014] Two groups of mounting frames, with two mounting frames in a group, symmetrically installed inside the outer box;

[0015] Four groups of inclined driving rollers, with two inclined driving rollers in a group. The four groups of inclined driving rollers are respectively rotationally installed on the four mounting frames in an up-and-down symmetrical manner;

[0016] Four groups of first motors, with two first motors in a group, respectively fixedly installed on the four mounting frames, respectively driving the respective inclined driving rollers to rotate;

[0017] A support frame, installed inside the outer box. One end of all the inclined driving rollers facing away from the mounting frames is rotationally supported by the support frame;

[0018] The mounting bracket can mount and support the inclined drive rollers. After the first motor is started, the output shaft drives the connected inclined drive rollers to rotate. The other end of the inclined drive roller is rotationally supported by the support frame. The four groups of inclined drive rollers are arranged to drive the activated carbon fiber felt from the two edges on both sides of the activated carbon fiber felt. Among the two inclined drive rollers in the same group, the inclined drive roller located above has a smaller extrusion force on the activated carbon fiber felt. When the inclined drive roller located above drives the activated carbon fiber felt, it will not cause the activated carbon fiber felt to be driven backward upward due to the driving direction being opposite to that of the inclined drive roller below. Instead, the driving direction of the activated carbon fiber felt is controlled by the inclined drive roller below. And the driving direction of the inclined drive roller located above is to drive towards the upper edge of the activated carbon fiber felt, and the driving direction of the inclined drive roller located below is to drive towards the lower edge of the activated carbon fiber felt. Thus, through the arrangement of the four groups of inclined drive rollers, the four corners of the activated carbon fiber felt are driven towards the edge of the activated carbon fiber felt, thereby realizing the stretching and unfolding of the activated carbon fiber felt.

[0019] Preferably, the stretching assembly further includes:

[0020] Four mounting grooves, respectively opened on the outer walls of the inclined drive rollers located above in each group;

[0021] Four rolling combs, respectively fixedly installed inside the four mounting grooves;

[0022] Mounting grooves are opened on the outer walls of the inclined drive rollers located above, enabling the installation of rolling combs inside the mounting grooves. Thus, when the inclined drive rollers located above rotate and drive, they can drive the rolling combs to rotate. On the one hand, when the rolling combs rotate, they can also realize the stretching effect on the activated carbon fiber felt. On the other hand, when the rolling combs rotate, they can comb and clean the surface of the activated carbon fiber felt. Therefore, when driving, stretching and unfolding the activated carbon fiber felt, it can comb and clean the dust on the surface of the activated carbon fiber felt, which is beneficial for the preliminary cleaning of the activated carbon fiber felt to avoid excessive dust adhering to the surface of the activated carbon fiber felt and causing a burden on the cleaning assembly.

[0023] Preferably, the cleaning assembly includes:

[0024] The first air pressure tank, the second air pressure tank, the third air pressure tank, and the fourth air pressure tank are all fixed inside the outer box body, and a through port is provided at one end facing the activated carbon fiber felt. The end of the activated carbon fiber felt passes downward between the third air pressure tank and the fourth air pressure tank, and then passes upward between the first air pressure tank and the second air pressure tank;

[0025] A gas-liquid dual-use pump, fixed inside the outer box body, and connected to the fourth air pressure tank through the input end;

[0026] A collection box, fixed on the outer wall of the outer box body, and communicating with the output end of the gas-liquid dual-purpose pump;

[0027] A first air pump, fixed between the second air pressure box and the third air pressure box, communicating with the second air pressure box through the input end, and communicating with the third air pressure box through the output end;

[0028] A second air pump, fixed inside the outer box body, and communicating with the first air pressure box through the output end;

[0029] After the second air pump is started, air is conveyed into the first air pressure box. The air inside the first air pressure box is conveyed to the surface of the activated carbon fiber felt along the through hole. After the first air pump is started, the gas inside the second air pressure box is pumped out and conveyed into the third air pressure box, so that a negative pressure is generated inside the second air pressure box. Under the action of the negative pressure, combined with the through hole opposite to the first air pressure box of the second air pressure box, the air flow discharged from the first air pressure box passes through the activated carbon fiber felt through the through hole and then enters the second air pressure box. Therefore, it is beneficial to promote the air flow to pass through the activated carbon fiber felt to perform secondary cleaning or drying treatment on the cleaned activated carbon fiber felt. The air flow entering the third air pressure box passes through the through hole and is conveyed to the surface of the activated carbon fiber felt. The gas-liquid dual-purpose pump pumps out the gas inside the fourth air pressure box to make the inside of the fourth air pressure box in a negative pressure state, and also makes the air flow pass through the activated carbon fiber felt and then enter the fourth air pressure box through the through hole. Therefore, within the stretching range of the stretching assembly, the dust attached inside the activated carbon fiber felt is cleaned by the high-pressure air flow.

[0030] Preferably, the cleaning assembly further includes:

[0031] An ultrasonic water tank, fixed inside the outer box body;

[0032] An arc-shaped guiding plate, arranged inside the ultrasonic water tank;

[0033] Two cylinders, symmetrically fixed inside the ultrasonic water tank, and the two cylinders jointly drive the arc-shaped guiding plate to move vertically through the telescopic ends;

[0034] Two second driving members, installed inside the ultrasonic water tank, for driving the activated carbon fiber felt to bend and turn inside the ultrasonic water tank;

[0035] The cylinder drives the arc-shaped guide plate to move vertically through the end of the telescopic rod. When the arc-shaped guide plate moves vertically to the highest point, after the activated carbon fiber felt passes through the stretching assembly, it turns under the guiding action of the arc-shaped guide plate, so that the activated carbon fiber felt turns to move upward after passing through the arc-shaped guide plate. Subsequently, it is driven by the first driving part to output. After guiding the activated carbon fiber felt, the cylinder drives the arc-shaped guide plate to move downward to the lowest point, and no longer guides and supports the activated carbon fiber felt, so that the activated carbon fiber felt is completely exposed inside the ultrasonic water tank. The inside of the ultrasonic water tank contains a cleaning liquid, and the cleaning liquid cleans the activated carbon fiber felt immersed and exposed in the cleaning liquid inside the ultrasonic water tank under the action of ultrasonic waves, which is beneficial to cleaning the activated carbon fiber felt again, cleaning the residual dust inside the activated carbon fiber felt again, and cleaning the dust attached to the surface after the high-pressure air flow cleaning again, so as to improve the cleaning effect of the activated carbon fiber felt;

[0036] Two second driving parts can clamp and drive the position where the activated carbon fiber felt enters the ultrasonic water tank and the position where it exits the ultrasonic water tank. The second driving part has the same structure as the first driving part to clamp and drive the activated carbon fiber felt.

[0037] Preferably, the cleaning assembly further includes:

[0038] A heating wire is installed inside the first air pressure tank;

[0039] The heating wire can heat the air flow entering the inside of the first air pressure tank, so that the air flow discharged from the inside of the first air pressure tank and passing through the activated carbon fiber felt is a heated air flow. Thus, through the heating effect on the air flow, the drying effect of the air flow on the activated carbon fiber felt is improved.

[0040] Preferably, the cleaning assembly further includes:

[0041] A water tank, fixed on the top of the third air pressure tank;

[0042] A number of high-pressure spray heads, connected and fixed on the side wall of the water tank facing the activated carbon fiber felt;

[0043] A water pump, fixed on the outer wall of the ultrasonic water tank, used to transport the cleaning liquid inside the ultrasonic water tank to the water tank;

[0044] A recovery water tank, fixed on the top of the fourth air pressure tank, connected to the fourth air pressure tank through a communication port, arranged opposite to the water tank, and also provided with a through hole on the side facing the activated carbon fiber felt;

[0045] The water pump transports the cleaning liquid inside the ultrasonic water tank to the water tank. The cleaning liquid inside the water tank is sprayed out under high pressure by a high-pressure nozzle. The sprayed high-pressure cleaning liquid passes through the activated carbon fiber felt. Thus, when stretching the activated carbon fiber felt, the high-pressure cleaning liquid passes through it to improve the dust cleaning effect on the activated carbon fiber felt. After the cleaning liquid passes through the activated carbon fiber felt, it enters the inside of the recovery water tank. The inside of the recovery water tank is connected to the third air pressure tank through a communication port. At this time, the flow rate of the gas-liquid dual-use pump is greater than that of the first air pump, so that the air flow output by the first air pump into the third air pressure tank is not sufficient to meet the discharge volume inside the fourth air pressure tank. As a result, a negative pressure is formed inside the third air pressure tank. Under the action of the negative pressure, the air flow and the cleaning liquid inside the recovery water tank pass through the communication port and enter the inside of the third air pressure tank, and then pass through the activated carbon fiber felt again and enter the inside of the fourth air pressure tank, which is conducive to improving the dust cleaning efficiency of the activated carbon fiber felt.

[0046] Preferably, the cleaning assembly further includes:

[0047] A one-way valve, which is installed through the top of the recovery water tank;

[0048] The setting of the one-way valve enables the air flow to only enter the inside of the recovery water tank unidirectionally. When the air flow inside the recovery water tank is not sufficient to supplement the flow difference of the third air pressure tank, the external air flow can be supplemented through the one-way valve to avoid the situation of forming too large an air pressure difference and affecting the cleaning effect.

[0049] Preferably, the cleaning assembly further includes:

[0050] An inlet pipe, which is fixedly connected to the top of one end of the ultrasonic water tank;

[0051] An outlet pipe, which is fixedly connected to the bottom of the other end of the ultrasonic water tank. Control valves are installed inside both the inlet pipe and the outlet pipe;

[0052] The inlet pipe can be connected to an external water tank and a water pump to transport new cleaning liquid into the ultrasonic water tank. The outlet pipe can be connected to an external sewage tank and a water pump to discharge the cleaned cleaning liquid inside the ultrasonic water tank, which is conducive to replacing the cleaning liquid inside the ultrasonic water tank and thus conducive to maintaining the cleaning effect on the activated carbon fiber felt.

[0053] Preferably, the stretching assembly further includes:

[0054] Two first inner cavities, which are opened inside the upper end of the support frame;

[0055] Four second inner cavities, which are opened inside the upper inclined driving roller. The first inner cavity communicates with the second inner cavity;

[0056] The first connecting pipe communicates with one of the first inner cavities and the input end of the gas-liquid dual-purpose pump;

[0057] The second connecting pipe communicates with the other first inner cavity and the input end of the first air pump;

[0058] The first connecting pipe connects one of the first inner cavities and the input end of the gas-liquid dual-purpose pump, and the second connecting pipe communicates with the other first inner cavity and the input end of the first air pump, so as to generate negative pressure inside the first inner cavity, and thus generate negative pressure inside the second inner cavity. The second inner cavity communicates with the rolling comb through a number of ventilation holes, so that when the rolling comb combs and cleans the surface of the activated carbon fiber felt, the dust brushed out can be recovered synchronously, which is beneficial to avoid the situation that the brushed dust accumulates and affects the cleaning effect.

[0059] Compared with the prior art, the present invention has the following beneficial effects:

[0060] Through the setting of the stretching component and the cleaning component, the activated carbon fiber felt is expanded in all directions under the stretching action of the stretching component, so that gaps are generated between the originally tightly packed fiber layers, thereby exposing more internal pores and adsorption sites, making it easier to clean the dust. After the activated carbon fiber felt is stretched and unfolded, the cleaning component cleans the unfolded activated carbon fiber felt, thereby improving the cleaning effect on the activated carbon fiber felt.

[0070] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments in the following description are only examples, and those skilled in the art can think of other obvious variations.

[0071] As Figures 1 to 8 shown, a dust cleaning device for recycling activated carbon fiber felt includes an outer box body 1, and further includes:

[0072] Two openings 103, respectively penetrating through the top of the outer box body 1 for the activated carbon fiber felt to penetrate in and out;

[0073] A stretching assembly, installed inside the outer box body 1, for stretching and expanding the passing activated carbon fiber felt;

[0074] A cleaning assembly, installed inside the outer box body 1, for cleaning the expanded activated carbon fiber felt;

[0075] A first driving member 102, installed inside the outer box body 1, for driving the cleaned activated carbon fiber felt to pass out through one of the openings 103;

[0076] During the dust treatment process of activated carbon fiber felt, due to its complex microporous structure inside, dust is likely to hide in it and is difficult to be thoroughly cleaned. This not only reduces the adsorption efficiency of the activated carbon fiber felt, but also may affect its service life. In order to improve the cleaning effect, it is usually necessary to stretch and expand the activated carbon fiber felt. Stretching and expanding can create gaps between the originally tightly packed fiber layers, thereby exposing more internal pores and adsorption sites, making it easier for dust to be cleaned out;

[0077] This embodiment of the present invention can solve the above problems. The specific implementation is as follows. When cleaning the activated carbon fiber felt, the activated carbon fiber felt to be cleaned is inserted into the interior of the opening 103. After the activated carbon fiber felt is inserted, the stretching assembly first conveys the activated carbon fiber felt into the interior of the outer box 1 until the activated carbon fiber felt is conveyed and guided to the bottom of the stretching assembly. Then, the stretching assembly starts to stretch and expand the activated carbon fiber felt, so that the activated carbon fiber felt is expanded in all directions under the stretching action of the stretching assembly, causing gaps to be generated between the originally closely packed fiber layers, thereby exposing more internal pores and adsorption sites, making it easier to clean out the dust. After the activated carbon fiber felt is stretched and unfolded, the cleaning assembly cleans the unfolded activated carbon fiber felt, thereby improving the cleaning effect of the activated carbon fiber felt;

[0078] After the cleaning of the activated carbon fiber felt is completed, under the driving action of the first driving member 102, the activated carbon fiber felt is output outward from the interior of the other opening 103, thus completing the entire cleaning process of the activated carbon fiber felt;

[0079] The first driving member 102 includes two horizontal driving rollers symmetrically arranged on both sides of the activated carbon fiber felt, and two driving motors for driving the horizontal driving rollers to rotate. After the horizontal driving rollers rotate, they jointly squeeze and convey the activated carbon fiber felt to realize the output driving of the cleaned activated carbon fiber felt.

[0080] As an alternative embodiment, the stretching assembly includes:

[0081] Two sets of mounting frames 201. Two mounting frames 201 form a set and are symmetrically mounted inside the outer box 1;

[0082] Four sets of inclined driving rollers 2. Two inclined driving rollers 2 form a set. The four sets of inclined driving rollers 2 are respectively and symmetrically rotatably mounted on the four mounting frames 201 up and down;

[0083] Four sets of first motors 202. Two first motors 202 form a set and are respectively fixedly mounted on the four mounting frames 201 to drive the respective inclined driving rollers 2 to rotate;

[0084] A support frame 203 is mounted inside the outer box 1. One end of all the inclined driving rollers 2 facing away from the mounting frame 201 is rotatably supported by the support frame 203;

[0085] The mounting bracket 201 can mount and support the inclined drive roller 2. After the first motor 202 is started, it drives the connected inclined drive roller 2 to rotate through the output shaft. The other end of the inclined drive roller 2 is rotationally supported by the support frame 203. The four groups of inclined drive rollers 2 are arranged to drive the activated carbon fiber felt from the two edges on both sides of the activated carbon fiber felt. Among the two inclined drive rollers 2 in the same group, the inclined drive roller 2 located above has a smaller extrusion force on the activated carbon fiber felt. When the inclined drive roller 2 located above drives the activated carbon fiber felt, it will not cause the activated carbon fiber felt to be driven back upward due to the driving direction being opposite to that of the inclined drive roller 2 below. Instead, the driving direction of the activated carbon fiber felt is controlled by the inclined drive roller 2 below, and the driving direction of the inclined drive roller 2 located above is to drive towards the upper edge of the activated carbon fiber felt, and the driving direction of the inclined drive roller 2 located below is to drive towards the lower edge of the activated carbon fiber felt. Thus, through the arrangement of the four groups of inclined drive rollers 2, the four corners of the activated carbon fiber felt are driven towards the edge of the activated carbon fiber felt, thereby realizing the stretching and unfolding of the activated carbon fiber felt.

[0086] As an alternative embodiment, the stretching assembly further includes:

[0087] Four mounting grooves 301 are respectively opened on the outer walls of the inclined drive rollers 2 located above in each group;

[0088] Four rolling combs 3 are respectively fixedly installed inside the four mounting grooves 301;

[0089] The mounting grooves 301 are opened on the outer walls of the inclined drive rollers 2 located above, enabling the rolling combs 3 to be installed inside the mounting grooves 301. Thus, when the inclined drive rollers 2 located above rotate and drive, they can drive the rolling combs 3 to rotate. On the one hand, when the rolling combs 3 rotate, they can also realize the stretching effect on the activated carbon fiber felt. On the other hand, when the rolling combs 3 rotate, they can comb and clean the surface of the activated carbon fiber felt. Therefore, when driving and stretching the activated carbon fiber felt, the dust on the surface of the activated carbon fiber felt can be combed and cleaned, which is beneficial for the preliminary cleaning of the activated carbon fiber felt to avoid overloading the cleaning assembly when the amount of dust attached to the surface of the activated carbon fiber felt is too large.

[0090] As an alternative embodiment, the cleaning assembly includes:

[0091] The first air pressure box 4, the second air pressure box 401, the third air pressure box 402, and the fourth air pressure box 403 are all fixed inside the outer box 1, and a through hole is provided at one end facing the activated carbon fiber felt. The end of the activated carbon fiber felt passes downward between the third air pressure box 402 and the fourth air pressure box 403, and then passes upward between the first air pressure box 4 and the second air pressure box 401;

[0092] The gas-liquid dual-use pump 404 is fixed inside the outer box body 1 and is connected to the fourth air pressure tank 403 through the input end;

[0093] The collection tank 405 is fixed on the outer wall of the outer box body 1 and is connected to the output end of the gas-liquid dual-use pump 404;

[0094] The first air pump 406 is fixed between the second air pressure tank 401 and the third air pressure tank 402, is connected to the second air pressure tank 401 through the input end, and is connected to the third air pressure tank 402 through the output end;

[0095] The second air pump 407 is fixed inside the outer box body 1 and is connected to the first air pressure tank 4 through the output end;

[0096] After the second air pump 407 is started, air flow is delivered into the first air pressure tank 4. The air flow inside the first air pressure tank 4 is delivered to the surface of the activated carbon fiber felt along the through-hole. After the first air pump 406 is started, the gas inside the second air pressure tank 401 is pumped out and delivered into the third air pressure tank 402, so that a negative pressure is generated inside the second air pressure tank 401. Under the action of the negative pressure, combined with the through-hole between the second air pressure tank 401 and the first air pressure tank 4, the air flow discharged from the first air pressure tank 4 passes through the activated carbon fiber felt through the through-hole and then enters the second air pressure tank 401, which is beneficial to promoting the air flow to pass through the activated carbon fiber felt to perform secondary cleaning or drying treatment on the activated carbon fiber felt after cleaning. The air flow entering the third air pressure tank 402 passes through the through-hole and is delivered to the surface of the activated carbon fiber felt. The gas-liquid dual-use pump 404 pumps out the gas inside the fourth air pressure tank 403 to make the inside of the fourth air pressure tank 403 in a negative pressure state, and similarly makes the air flow pass through the activated carbon fiber felt and then enter the fourth air pressure tank 403 through the through-hole, so that inside the stretching range of the stretching assembly, the dust attached to the inside of the activated carbon fiber felt is cleaned by the high-pressure air flow.

[0097] As an alternative embodiment, the cleaning assembly further includes:

[0098] The ultrasonic water tank 101 is fixed inside the outer box body 1;

[0099] The arc-shaped guide plate 5 is arranged inside the ultrasonic water tank 101;

[0100] Two air cylinders 501 are symmetrically fixed inside the ultrasonic water tank 101, and the two air cylinders 501 jointly drive the arc-shaped guide plate 5 to move vertically through the telescopic ends;

[0101] Two second driving members 502 are installed inside the ultrasonic water tank 101 and are used to drive the activated carbon fiber felt to bend and turn inside the ultrasonic water tank 101;

[0102] The cylinder 501 drives the arc-shaped guide plate 5 to move vertically through the end of the telescopic rod. When the arc-shaped guide plate 5 moves vertically to the highest point, after passing through the stretching assembly, the activated carbon fiber felt is steered under the guiding action of the arc-shaped guide plate 5, so that the activated carbon fiber felt turns to move upward after passing through the arc-shaped guide plate 5. Subsequently, it is driven by the first driving member 102 to output. After guiding the activated carbon fiber felt, the cylinder 501 drives the arc-shaped guide plate 5 to move downward to the lowest point, and no longer guides and supports the activated carbon fiber felt, making the activated carbon fiber felt completely exposed inside the ultrasonic water tank 101. The ultrasonic water tank 101 contains a cleaning liquid, and the cleaning liquid cleans the activated carbon fiber felt immersed and exposed in the cleaning liquid inside the ultrasonic water tank 101 under the ultrasonic action, which is beneficial to cleaning the activated carbon fiber felt again, cleaning the residual dust inside the activated carbon fiber felt again, and cleaning the dust attached to the surface after cleaning by high-pressure air flow again, so as to improve the cleaning effect of the activated carbon fiber felt;

[0103] The two second driving members 502 can clamp and drive the position where the activated carbon fiber felt enters the ultrasonic water tank 101 and the position where it exits the ultrasonic water tank 101. The second driving member 502 has the same structure as the first driving member 102 to clamp and drive the activated carbon fiber felt.

[0104] As an alternative embodiment, the cleaning assembly further includes:

[0105] A heating wire is installed inside the first air pressure tank 4;

[0106] The heating wire can heat the air flow entering the inside of the first air pressure tank 4, so that the air flow discharged from the inside of the first air pressure tank 4 and passing through the activated carbon fiber felt is heated air flow. Thus, through the heating effect on the air flow, the drying effect of the air flow on the activated carbon fiber felt is improved.

[0107] As an alternative embodiment, the cleaning assembly further includes:

[0108] A water tank 6 is fixed to the top of the third air pressure tank 402;

[0109] A number of high-pressure nozzles 601 are connected and fixed to one side wall of the water tank 6 facing the activated carbon fiber felt;

[0110] A water pump 602 is fixed to the outer wall of the ultrasonic water tank 101 and is used to convey the cleaning liquid inside the ultrasonic water tank 101 to the water tank 6;

[0111] A recovery water tank 603 is fixed to the top of the fourth air pressure tank 403, is connected to the fourth air pressure tank 403 through a communication port 604, is arranged opposite to the water tank 6, and a through hole is also opened on the side facing the activated carbon fiber felt;

[0112] The water pump 602 transports the cleaning liquid inside the ultrasonic water tank 101 to the water tank 6. The cleaning liquid transported to the inside of the water tank 6 is ejected under high pressure by the high-pressure nozzle 601. The ejected high-pressure cleaning liquid passes through the activated carbon fiber felt. Thus, when the activated carbon fiber felt is stretched, the high-pressure cleaning liquid passes through it to improve the dust cleaning effect on the activated carbon fiber felt. After the cleaning liquid passes through the activated carbon fiber felt, it enters the inside of the recovery water tank 603. The inside of the recovery water tank 603 is connected to the third air pressure tank 402 through the communication port 604. At this time, the flow rate of the air-liquid dual-purpose pump 404 is set to be greater than the flow rate of the first air pump 406, so that the air flow output by the first air pump 406 to the inside of the third air pressure tank 402 is not sufficient to meet the discharge amount inside the fourth air pressure tank 403. As a result, a negative pressure is formed inside the third air pressure tank 402. Under the action of the negative pressure, the air flow and the cleaning liquid inside the recovery water tank 603 pass through the communication port 604 and enter the inside of the third air pressure tank 402, and then pass through the activated carbon fiber felt again and enter the inside of the fourth air pressure tank 403, which is beneficial to improving the dust cleaning efficiency of the activated carbon fiber felt.

[0113] As an alternative embodiment, the cleaning assembly further includes:

[0114] A one-way valve 8, which is installed through the top of the recovery water tank 603;

[0115] The setting of the one-way valve 8 enables the air flow to only enter the inside of the recovery water tank 603 unidirectionally. When the air flow inside the recovery water tank 603 is not sufficient to supplement the flow rate difference of the third air pressure tank 402, the external air flow can be supplemented through the one-way valve 8 to avoid the occurrence of a situation where an excessive air pressure difference affects the cleaning effect.

[0116] As an alternative embodiment, the cleaning assembly further includes:

[0117] An inlet pipe 901, which is fixedly connected to the top of one end of the ultrasonic water tank 101;

[0118] An outlet pipe 902, which is fixedly connected to the bottom of the other end of the ultrasonic water tank 101. Control valves are installed inside both the inlet pipe 901 and the outlet pipe 902;

[0119] The inlet pipe 901 can be connected to an external water tank and a water pump to transport new cleaning liquid to the inside of the ultrasonic water tank 101. The outlet pipe 902 can be connected to an external sewage tank and a water pump to discharge the cleaned cleaning liquid inside the ultrasonic water tank 101, which is beneficial to replacing the cleaning liquid inside the ultrasonic water tank 101 and thus beneficial to maintaining the cleaning effect on the activated carbon fiber felt.

[0120] As an alternative embodiment, the stretching assembly further includes:

[0121] Two first inner cavities 7, which are opened inside the upper end of the support frame 203;

[0122] Four second inner cavities 701 are opened inside the inclined driving roller 2 located above, and the first inner cavity 7 communicates with the second inner cavity 701;

[0123] The first connecting pipe 702 communicates one of the first inner cavities 7 with the input end of the gas-liquid dual-purpose pump 404;

[0124] The second connecting pipe 703 communicates the other first inner cavity 7 with the input end of the first air pump 406;

[0125] The first connecting pipe 702 connects one of the first inner cavities 7 with the input end of the gas-liquid dual-purpose pump 404, and the second connecting pipe 703 communicates the other first inner cavity 7 with the input end of the first air pump 406, so as to generate negative pressure inside the first inner cavity 7, thereby generating negative pressure inside the second inner cavity 701. The second inner cavity 701 communicates with the rolling comb 3 through a plurality of ventilation holes, so that when the rolling comb 3 combs and cleans the surface of the activated carbon fiber felt, the brushed dust can be recycled synchronously, which is beneficial to avoiding the situation that the brushed dust accumulates and affects the cleaning effect.

[0126] The working principle of the present invention: When cleaning the activated carbon fiber felt, the activated carbon fiber felt to be cleaned is inserted from the inside of the opening 103. After the activated carbon fiber felt is inserted, the stretching assembly first conveys the activated carbon fiber felt into the inner part of the outer box body 1 until the activated carbon fiber felt is conveyed and guided to the bottom of the stretching assembly. Then the stretching assembly starts to stretch and expand the activated carbon fiber felt, so that the activated carbon fiber felt is expanded around under the stretching action of the stretching assembly, so as to generate gaps between the originally tightly packed fiber layers, thereby exposing more internal pores and adsorption sites, making it easier to clean the dust. After the activated carbon fiber felt is stretched and unfolded, the cleaning assembly cleans the unfolded activated carbon fiber felt, thereby improving the cleaning effect on the activated carbon fiber felt;

[0127] After the activated carbon fiber felt is cleaned, through the driving action of the first driving member 102, the activated carbon fiber felt is output from the inside of the other opening 103, thereby completing the entire cleaning process of the activated carbon fiber felt;

[0128] The first driving member 102 includes two horizontal driving rollers symmetrically arranged on both sides of the activated carbon fiber felt, and two driving motors for driving the horizontal driving rollers to rotate. After the horizontal driving rollers rotate, they jointly squeeze and convey the activated carbon fiber felt to realize the output driving of the cleaned activated carbon fiber felt.

Those skilled in the art should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification is only the principle of the present invention. Without departing from the spirit and scope of the present invention, various changes and improvements will occur to the present invention, and all these changes and improvements fall within the scope of the present invention claimed.
