Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of waste gas pollutant treatment, in particular to an activated carbon collecting device. BACKGROUND

[0002] Activated carbon can effectively adsorb various pollutants in waste gas, such as organic compounds, sulfur dioxide, nitrogen oxides, etc. In the printing, spraying, rubber, petrochemical and other industries, activated carbon is often used to treat volatile organic compound waste gas. These waste gases usually contain harmful substances such as benzene, toluene, xylene, etc., which pose a threat to human health and the ecological environment. Through activated carbon adsorption technology, the emission concentration of these waste gases can be significantly reduced, and the air quality can be improved.

[0003] In related technologies, the adsorption capacity of activated carbon is limited, and when activated carbon reaches a saturated state, its adsorption effect will be greatly reduced. Therefore, in actual application, activated carbon needs to be pretreated by desorption after a long time of adsorption is completed, and the adsorption effect of activated carbon will be significantly improved after desorption treatment. The current conventional method is to collect the activated carbon after adsorption is completed and put it into the corresponding desorption pretreatment device for desorption. However, such a desorption device is often independent of the activated carbon adsorption waste gas device, and the staff often needs to transfer the collected activated carbon to the corresponding desorption device to complete the desorption of the activated carbon, which makes the whole desorption process of the activated carbon very cumbersome and has low flexibility, resulting in that the activated carbon cannot be desorbed in the first time after adsorbing waste gas, which is not conducive to the daily use of activated carbon. SUMMARY

[0004] The present application provides an activated carbon collecting device, which aims to optimize the activated carbon adsorption and desorption pretreatment steps, so that the activated carbon can be pretreated and collected in the first time after completing the adsorption of waste gas, thereby significantly improving the pretreatment efficiency between activated carbon adsorption and desorption, and the activated carbon can be desorbed in time after the pretreatment efficiency of the activated carbon desorption is improved, thereby ensuring the efficiency of the daily treatment of waste gas by activated carbon.

[0005] The present application provides an activated carbon collecting device, which adopts the following technical solution:

[0006] An activated carbon collection device includes a casing with an inlet and an outlet on its upper and lower sides, respectively, which are connected. The casing is hollow, and a first guide plate and a second guide plate are installed inside the casing. The first and second guide plates are staggered vertically within the casing and are both inclined. One end of the first guide plate is located below the inlet, and one end of the second guide plate is located above the outlet. A corresponding material guiding channel is formed between the first guide plate and the second guide plate. The inner wall of the casing is tightly fitted with a smoke exhaust fan and a hot air fan. The end of the first guide plate away from the feed inlet corresponds to the smoke exhaust fan, and the end of the second guide plate near the discharge outlet corresponds to the hot air fan. A smoke outlet is provided on the inner wall of the casing away from the smoke exhaust fan. The smoke outlet is connected to the smoke exhaust fan. A material control plate is added vertically at the feed inlet. The material control plate is used to control the amount of activated carbon entering the casing from the feed inlet.

[0007] The first guide plate includes a fixed frame, a movable plate, and an elastic element. The fixed frame is rotatably installed inside the machine housing. The fixed frame is hollow inside and has an open top. The movable plate is installed near the top of the fixed frame, and the left and right ends of the movable plate are in contact with the left and right sides of the fixed frame. The elastic element is integrally connected between the movable plate and the inner wall of the fixed frame in a direction perpendicular to the movable plate.

[0008] By adopting the above technical solution, activated carbon adsorbs and treats the waste gas entering the machine during the conveying process, and performs desorption pretreatment as soon as possible. After the desorption treatment is completed, the activated carbon is discharged out of the machine through the outlet and collected again for the next use.

[0009] After the activated carbon on the first guide plate adsorbs the waste gas, it is conveyed to the second guide plate. A hot air blower blows hot air onto the second guide plate to heat up the activated carbon after adsorption. The activated carbon will then undergo desorption after heating, which allows the activated carbon to undergo desorption pretreatment as soon as possible. This helps to shorten the time for the activated carbon to have a secondary adsorption function and greatly improves the efficiency of activated carbon reuse.

[0010] This setup optimizes the pretreatment steps of activated carbon adsorption and desorption, allowing activated carbon to undergo desorption pretreatment and be collected immediately after adsorbing waste gas. This significantly improves the efficiency of pretreatment between adsorption and desorption, enabling timely adsorption of waste gas and ensuring the efficiency of daily waste gas treatment by activated carbon.

[0011] In summary, the active carbon is transported on the first guide plate, which is the process of adsorbing the waste gas. The active carbon after adsorption is transported to the second guide plate, and the transportation on the second guide plate is the process of using the hot air machine to desorb the active carbon. The machine box is used to concentrate the adsorption and desorption of the active carbon in one device, which effectively shortens the interval time between the adsorption and desorption of the active carbon, and greatly improves the efficiency of the reuse of the active carbon.

[0012] Preferably, the machine box is further provided with an elastic plate, the elastic plate is located above the fixed frame, the overall installation direction of the elastic plate is parallel to the fixed frame, the left and right sides of the end of the elastic plate away from the fixed frame and the top of the machine box are connected by corresponding connecting rods, the side of the elastic plate close to the fixed frame is curved, and a guide channel for transporting the active carbon is formed between the elastic plate and the movable plate.

[0013] By adopting the above technical scheme, when the active carbon falls on the movable plate from the feeding port, the active carbon bounces up and abuts against the elastic plate, the elastic force of the elastic plate accelerates the speed of the active carbon falling on the movable plate again, thereby increasing the number of times of bouncing of the active carbon between the movable plate and the elastic plate, and thereby increasing the contact time between the waste gas and the active carbon, and thereby effectively increasing the adsorption effect of the active carbon on the waste gas.

[0014] The side of the elastic plate close to the movable plate is curved, which is because the height of each bounce of the active carbon is gradually reduced due to air resistance as the active carbon repeatedly rises and falls between the movable plate and the elastic plate. In order to make the active carbon abut against the elastic plate smoothly when bouncing, the side of the elastic plate close to the movable plate is curved, so that the distance between the part of the elastic plate close to the tail end of the movable plate and the movable plate is closer, thereby facilitating the active carbon to abut against the elastic plate smoothly when bouncing, and thereby effectively ensuring the bouncing of the active carbon between the movable plate and the elastic plate.

[0015] Preferably, the fixed frame is rotatably installed in the machine box.

[0016] By adopting the above technical scheme, when the amount of waste gas to be adsorbed is small, the active carbon and the waste gas do not need to be in contact for a long time. At this time, the angle of inclination of the fixed frame is increased, so that the speed of the active carbon transported on the movable plate is increased, which is beneficial to save time. When the amount of waste gas to be adsorbed is large, the contact time between the active carbon and the waste gas is increased. At this time, the angle of inclination of the fixed frame is reduced, so that the time of the active carbon transported on the movable plate is increased, thereby effectively increasing the contact time between the active carbon and the waste gas, and improving the adsorption effect of the active carbon on the waste gas.

[0017] Preferably, a support box is fastened outside the case, a rotating knob is mounted outside the support box, a drive gear is arranged in the support box, the rotating knob and the drive gear are connected through a corresponding rotating shaft, a drive rack is arranged in the support box, the drive rack is vertically arranged, the drive gear and the drive rack are connected in meshing, and an adapter rod is arranged between the bottom of the drive rack and the fixed frame, and the end of the adapter rod is integrally connected with the fixed frame.

[0018] By adopting the above technical scheme, when the inclination angle of the fixed frame needs to be adjusted, the rotating knob is rotated, the rotating knob drives the drive gear to rotate, the drive gear drives the drive rack to rise and fall in the vertical direction during the rotation of the drive gear, and the drive rack drives the fixed frame to rise and fall through the adapter rod. The end of the fixed frame is hingedly mounted in the case through a corresponding hinge shaft, so that when the middle part of the fixed frame rises and falls in the vertical direction, the fixed frame rotates in the case.

[0019] Preferably, a curved first waist-shaped hole is formed in the vertical direction on the side wall of the case, and a second waist-shaped hole is formed in the horizontal direction on the bottom of the drive rack, and the left and right ends of the adapter rod are respectively inserted into the first waist-shaped hole and the second waist-shaped hole.

[0020] By adopting the above technical scheme, since the rotating track of the fixed frame is overall arc-shaped and the movement track of the drive rack is vertical, the left and right ends of the adapter rod are respectively inserted into the first waist-shaped hole and the second waist-shaped hole, which can effectively avoid movement interference between them.

[0021] Preferably, the control plate is rotatably mounted at the feeding port.

[0022] By adopting the above technical scheme, the purpose is to adaptively adjust the size of the feeding port and the feeding angle of the activated carbon by rotating the control plate. Adjusting the size of the feeding port can adjust the feeding amount of the activated carbon, and adjusting the feeding angle of the activated carbon can effectively adjust the conveying time of the activated carbon on the movable plate, so that the activated carbon can be more flexible and adaptive when adsorbing waste gas.

[0023] Preferably, a drive motor is fastened on the outer wall of the case, a lead screw is mounted on the drive end of the drive motor in the horizontal direction, a moving seat is threadedly sleeved on the lead screw, push plates are integrally connected to the upper and lower ends of the moving seat, and one end of the push plate away from the moving seat abuts against the control plate.

[0024] By adopting the technical scheme, when the angle of the material control plate needs to be adjusted, the driving motor drives the screw rod to rotate, the moving seat slides along the length direction of the screw rod towards the direction of approaching or moving away from the material control plate, the push plate on the moving seat pushes the material control plate, and the angle of the material control plate is adjusted.

[0025] Preferably, the low end of the fixed frame is connected with the inner wall of the smoke exhauster through the left and right linkage rods, and the fixed frame drives the smoke exhauster to ascend and descend in the vertical direction through the two linkage rods during rotation.

[0026] By adopting the technical scheme, the fixed frame rotates in the cabinet, and the smoke exhauster can be synchronously driven to ascend and descend in the vertical direction. This is to keep the outlet of the smoke exhauster at the low end of the fixed frame, thereby effectively avoiding the phenomenon that the outlet of the smoke exhauster is separated from the low end of the fixed frame during rotation of the fixed frame.

[0027] Preferably, the sidewalls of the two linkage rods are provided with corresponding third waist-shaped holes, the sliding blocks are inserted into the third waist-shaped holes, and the sidewalls of the sliding blocks are integrally formed with sliding plates, and the sliding plates are connected with the smoke exhauster.

[0028] By adopting the technical scheme, the sliding blocks move in the corresponding third waist-shaped holes during rotation of the fixed frame, and the sliding plates drive the smoke exhauster to ascend and descend, thereby keeping the air outlet of the smoke exhauster corresponding to the low end of the fixed frame at all times. Meanwhile, movement interference during rotation of the fixed frame and ascending and descending of the smoke exhauster can be effectively avoided.

[0029] In summary, the present application has at least one of the following beneficial technical effects:

[0030] 1. The activated carbon on the first guide plate adsorbs the waste gas and is conveyed to the second guide plate, the hot air blower blows hot air at the second guide plate, the blown hot air is used for temperature rising treatment of the activated carbon after adsorption, the activated carbon after temperature rising treatment is desorbed, thereby the activated carbon after adsorption can be desorbed in the first time, thereby the time for the activated carbon to have secondary adsorption effect is shortened, and the efficiency of repeated use of the activated carbon is greatly improved.

[0031] The setting mode can optimize the activated carbon adsorption and desorption pretreatment steps, the activated carbon can be pretreated and collected for desorption in the first time after completing the action of adsorbing waste gas, thereby the efficiency of pretreatment between activated carbon adsorption and desorption is significantly improved, the activated carbon can be desorbed in time after the efficiency of activated carbon desorption pretreatment is improved, thereby the efficiency of daily treatment of waste gas by the activated carbon is ensured.

[0032] In summary, the conveying of activated carbon on the first guide plate is the process of adsorption of waste gas. The adsorbed activated carbon is then conveyed to the second guide plate, where it undergoes a desorption pretreatment process using a hot air blower. By concentrating both adsorption and desorption pretreatment within a single unit, the time interval between adsorption and desorption pretreatment is effectively shortened, significantly improving the efficiency of activated carbon reuse.

[0033] 2. When the tilt angle of the fixed frame needs to be adjusted, turn the knob to drive the drive gear. During rotation, the drive gear causes the drive rack to move vertically up and down. Simultaneously, the drive rack moves the fixed frame up and down via the adapter rod. The ends of the fixed frame are hinged to the chassis via corresponding hinge shafts. Therefore, when the middle of the fixed frame moves vertically up and down, the fixed frame rotates within the chassis.

[0034] 3. As the fixed frame rotates within the casing, it simultaneously drives the exhaust fan to rise and fall vertically. This is done to ensure that the exhaust fan outlet is always positioned at the lower end of the fixed frame, effectively preventing the exhaust fan outlet from disengaging from the lower end of the fixed frame during rotation.

DETAILED DESCRIPTION

[0043] The following will be described in detail in combination with the accompanying drawings Figure 1 - the accompanying drawings Figure 7 , the present application is further described in detail.

[0044] Embodiment:

[0045] The embodiment of the present application discloses an active carbon collecting device, referring to Figure 1 and Figure 2 , including a cuboid-shaped case 1, the upper and lower sides of the case 1 are respectively provided with a feed inlet 2 and a discharge outlet 3, the feed inlet 2 and the discharge outlet 3 are kept in communication. The inside of the case 1 is hollow, and the inside of the case 1 is additionally provided with a first guide plate 4 and a second guide plate 5, the first guide plate 4 and the second guide plate 5 are staggered distributed up and down in the case 1, the first guide plate 4 is located above the second guide plate 5, and the first guide plate 4 and the second guide plate 5 are both inclinedly arranged. One end of the first guide plate 4 is located below the feed inlet 2, and one end of the second guide plate 5 is located above the discharge outlet 3. A corresponding guide channel is formed between the first guide plate 4 and the second guide plate 5, the active carbon falls on the first guide plate 4 through the feed inlet 2 and is conveyed in the case 1 through the guide channel, the active carbon adsorbs and treats the waste gas entering the case 1 in the conveying process, and carries out desorption pretreatment at the first time, and the active carbon after the desorption treatment is discharged out of the case 1 through the discharge outlet 3 and is collected again for next use.

[0046] Referring to Figure 1 and Figure 2The inner wall of the machine box 1 is fastened with the exhaust fan 6 and the hot air fan 7 through fastening bolts, the end of the first guide plate 4 away from the feeding port 2 corresponds to the exhaust fan 6, and the end of the second guide plate 5 close to the discharging port 3 corresponds to the hot air fan 7. The inner wall of the machine box 1 away from the exhaust fan 6 is provided with a smoke outlet 8, and the smoke outlet 8 and the exhaust fan 6 are in communication. The exhaust fan 6 is used to exhaust the waste gas generated in the production process into the machine box 1, and the waste gas is treated by adsorption through the activated carbon on the first guide plate 4. After the waste gas exhausted into the machine box 1 is adsorbed by the activated carbon, only a small part of the waste gas not adsorbed by the activated carbon is discharged out of the machine box 1 through the smoke outlet 8 for treatment, thereby greatly reducing the amount of waste gas that needs to be treated subsequently, thereby facilitating the reduction of the load of the subsequent waste gas treatment equipment and saving energy consumption.

[0047] The activated carbon on the first guide plate 4 is transported to the second guide plate 5 after adsorbing the waste gas, the hot air fan 7 blows hot air at the second guide plate 5, the activated carbon after adsorption is treated by heating, and the activated carbon after heating treatment will be desorbed, thereby the activated carbon after adsorption can be desorbed for pretreatment at the first time, thereby facilitating the shortening of the time for the activated carbon to have a secondary adsorption effect, and greatly improving the efficiency of the reuse of the activated carbon.

[0048] The setting mode can optimize the activated carbon adsorption and desorption pretreatment steps, so that the activated carbon can be pretreated and collected for desorption at the first time after completing the action of adsorbing the waste gas, thereby facilitating the significant improvement of the efficiency of the pretreatment between the activated carbon adsorption and desorption, and the efficiency of the activated carbon desorption pretreatment is improved, so that the next waste gas adsorption can be carried out in time, thereby facilitating the guarantee of the efficiency of the daily treatment of the waste gas by the activated carbon.

[0049] In summary, the activated carbon is transported on the first guide plate 4 to adsorb the waste gas. The activated carbon after adsorption is transported to the second guide plate 5, and the transportation on the second guide plate 5 is a process of pretreating the activated carbon by desorption using the hot air fan 7. The activated carbon adsorption and desorption pretreatment are concentrated in one device by using the machine box 1, which effectively shortens the interval time between the activated carbon adsorption and desorption pretreatment, and greatly improves the efficiency of the reuse of the activated carbon.

[0050] At the same time, referring to Figure 2 , Figure 3 and Figure 4 , the control plate 9 is additionally provided at the feeding port 2 in the vertical direction, and the control plate 9 is used to control the amount of activated carbon entering the machine box 1 from the feeding port 2, thereby enabling the staff to effectively control the amount of activated carbon according to the specific situation when treating the waste gas.

[0051] Specifically, referring to Figure 2 , Figure 3 andFigure 4 The first material guide plate 4 comprises a fixed frame 41, a movable plate 42 and elastic members 43. The fixed frame 41 is rotatably installed in the cabinet 1. The fixed frame 41 is in the shape of a cuboid, hollow inside and open at the top. The movable plate 42 is in the shape of a cuboid. The movable plate 42 is installed at the position close to the top of the fixed frame 41, and the left and right ends of the movable plate 42 are in close contact with the left and right sides of the fixed frame 41. The elastic members 43 are integrally connected between the bottom of the movable plate 42 and the inner wall of the fixed frame 41 in the direction perpendicular to the movable plate 42.

[0052] Specifically, when the activated carbon enters the cabinet 1 from the feeding port 2, the activated carbon falls on the movable plate 42 in the vertical direction. The movable plate 42 is compressed downward by the downward force of the activated carbon, and then bounces upward by the elastic force of the elastic members 43. The purpose of this is to make the activated carbon on the movable plate 42 continuously have the process of being thrown upward and falling downward when being transported on the movable plate 42. In this process, the exhaust gas discharged by the exhaust fan 6 can fully contact with the activated carbon, thereby improving the effect of the activated carbon on adsorbing the exhaust gas.

[0053] The traditional way of using activated carbon to adsorb exhaust gas is to store the activated carbon on the activated carbon bed, and then pass the exhaust gas into the activated carbon bed for treatment. Since the activated carbon is stored on the bed, the side of the activated carbon in close contact with the bed is in a blocked state, so that the activated carbon and the exhaust gas cannot fully contact, which reduces the effect of the activated carbon on adsorbing the exhaust gas.

[0054] In the embodiment, the movable plate 42 is used to make the activated carbon on the movable plate 42 continuously have the process of being thrown upward and falling downward when being transported on the movable plate 42. In this process, the exhaust gas discharged by the exhaust fan 6 can fully contact with the activated carbon, thereby improving the effect of the activated carbon on adsorbing the exhaust gas.

[0055] In the embodiment, the elastic members 43 are provided in multiple numbers, which are evenly arranged along the length direction of the movable plate 42, and the elastic members 43 can be springs.

[0056] Further, with reference to Figure 2 , Figure 3 and Figure 4The cabinet 1 is additionally provided with an elastic plate 10, which is made of elastic material and has elasticity. The elastic plate 10 is located above the fixed frame 41 and is parallel to the fixed frame 41. The left and right sides of the end of the elastic plate 10 away from the fixed frame 41 and the top of the cabinet 1 are connected by corresponding connecting rods, and the side of the elastic plate 10 close to the fixed frame 41 is curved.

[0057] Specifically, when the activated carbon falls on the movable plate 42 from the feeding port 2, the activated carbon bounces up and abuts against the elastic plate 10, the elastic force of the elastic plate 10 accelerates the speed of the activated carbon falling on the movable plate 42 again, thereby increasing the number of times of rebounding of the activated carbon between the movable plate 42 and the elastic plate 10, and thereby increasing the contact time between the waste gas and the activated carbon, thereby effectively increasing the effect of the activated carbon on the waste gas.

[0058] The side of the elastic plate 10 close to the movable plate 42 is curved, which is to solve the problem that the height of the activated carbon rebounding is gradually reduced due to air resistance when the activated carbon repeatedly rises and falls between the movable plate 42 and the elastic plate 10. In order to make the activated carbon abut against the elastic plate 10 smoothly when rebounding, the side of the elastic plate 10 close to the movable plate 42 is curved, so that the distance between the part of the elastic plate 10 close to the tail end of the movable plate 42 and the movable plate 42 is closer, thereby helping the activated carbon to abut against the elastic plate 10 smoothly when rebounding, thereby effectively ensuring the rebounding of the activated carbon between the movable plate 42 and the elastic plate 10.

[0059] Further, the fixed frame 41 is rotatably installed in the cabinet 1, which is to adjust the speed of the activated carbon flowing on the movable plate 42, thereby adjusting the contact time between the activated carbon and the waste gas.

[0060] When the amount of waste gas to be adsorbed is small, the activated carbon and the waste gas do not need to be in contact for a long time. At this time, the angle of inclination of the fixed frame 41 is increased, so that the speed of the activated carbon transported on the movable plate 42 is increased, which is beneficial to save time. When the amount of waste gas to be adsorbed is large, the contact time between the activated carbon and the waste gas is increased. At this time, the angle of inclination of the fixed frame 41 is reduced, so that the time of the activated carbon transported on the movable plate 42 is increased, thereby effectively increasing the contact time between the activated carbon and the waste gas, and improving the effect of the activated carbon on the waste gas.

[0061] Specifically, referring to Figure 2 and Figure 5The support box 11 is fastened outside the case 1, a rotating knob 12 is installed outside the support box 11, a driving gear 13 is arranged inside the support box 11, the rotating knob 12 and the driving gear 13 are connected through corresponding rotating shafts. Meanwhile, a driving rack 14 is arranged inside the support box 11, the driving rack 14 is arranged vertically, the driving gear 13 and the driving rack 14 are connected in meshing. A connecting rod 15 is arranged between the bottom of the driving rack 14 and the fixed frame 41, the end of the connecting rod 15 is integrally connected with the fixed frame 41. The part where the connecting rod 15 is connected with the fixed frame 41 is close to the middle part of the fixed frame 41.

[0062] Specifically, when the inclination angle of the fixed frame 41 needs to be adjusted, the rotating knob 12 is rotated to drive the driving gear 13 to rotate, the driving gear 13 drives the driving rack 14 to rise and fall in the vertical direction during the rotation, and the driving rack 14 drives the fixed frame 41 to rise and fall through the connecting rod 15 at the same time. The end of the fixed frame 41 is hingedly installed in the case 1 through a corresponding hinge shaft, so that the fixed frame 41 rotates in the case 1 when the middle part of the fixed frame 41 rises and falls in the vertical direction.

[0063] Further, referring to Figure 2 and Figure 5 , a curved first waist-shaped hole 16 is formed in the vertical direction on the side wall of the case 1, and a second waist-shaped hole 17 is formed in the horizontal direction at the bottom of the driving rack 14. The left and right ends of the connecting rod 15 are respectively inserted into the first waist-shaped hole 16 and the second waist-shaped hole 17. Since the rotation track of the fixed frame 41 is overall arc-shaped, and the movement track of the driving rack 14 is vertical, inserting the left and right ends of the connecting rod 15 into the first waist-shaped hole 16 and the second waist-shaped hole 17 respectively can effectively avoid movement interference between them.

[0064] Further, the control plate 9 is rotatably installed at the feeding port 2 of the case 1. The purpose of this is to adaptively adjust the size of the feeding port 2 and the feeding angle of the activated carbon by rotating the control plate 9. Adjusting the size of the feeding port 2 can adjust the feeding amount of the activated carbon, and adjusting the feeding angle of the activated carbon can effectively adjust the time of the activated carbon being conveyed on the movable plate 42, so that the activated carbon can be more flexible and adaptive when adsorbing exhaust gas.

[0065] Specifically, referring to Figure 1 , Figure 4 and Figure 6The outer wall of the cabinet 1 is fastened with a driving motor 18, the driving end of the driving motor 18 is installed with a screw rod 19 in the horizontal direction, the screw rod 19 is threadedly sleeved with a moving seat 20, the upper and lower ends of the moving seat 20 are integrally connected with a push plate 21, and the end of the push plate 21 away from the moving seat 20 abuts to the control material plate 9. The abutting part of the push plate 21 and the control material plate 9 is located in the middle part of the control material plate 9. The top of the control material plate 9 is hingedly installed on the cabinet 1 through a corresponding rotating shaft.

[0066] Specifically, when the angle of the control material plate 9 needs to be adjusted, the driving motor 18 drives the screw rod 19 to rotate, and at the same time, the moving seat 20 slides along the length direction of the screw rod 19 towards the control material plate 9 or away from the control material plate 9, the push plate 21 on the moving seat 20 pushes the control material plate 9, and then the angle of the control material plate 9 is adjusted.

[0067] Further, the fixed frame 41 rotates in the cabinet 1, and at the same time, can synchronously drive the smoke exhaust machine 6 to lift in the vertical direction. The purpose of this is to keep the outlet of the smoke exhaust machine 6 at the low end of the fixed frame 41 at all times, and then the phenomenon that the outlet of the smoke exhaust machine 6 is separated from the low end of the fixed frame 41 during the rotation of the fixed frame 41 can be effectively avoided.

[0068] Specifically, referring to Figure 2 , Figure 6 and Figure 7 , the low end of the fixed frame 41 and the inner wall of the smoke exhaust machine 6 are connected through the left and right two linkage rods 22, and the fixed frame 41 drives the smoke exhaust machine 6 to lift in the vertical direction through the two linkage rods 22 during the rotation.

[0069] At the same time, referring to Figure 2 , Figure 6 and Figure 7 , in order to avoid the motion interference during the rotation of the fixed frame 41 and the lifting of the smoke exhaust machine 6, the side wall of the two linkage rods 22 is provided with a corresponding third waist-shaped hole 23, the third waist-shaped hole 23 is inserted with a sliding block 24, the side wall of the sliding block 24 is integrally formed with a sliding plate 25, and the sliding plate 25 is connected with the smoke exhaust machine 6.

[0070] During the rotation of the fixed frame 41, the sliding block 24 moves in the corresponding third waist-shaped hole 23, and drives the smoke exhaust machine 6 to lift through the sliding plate 25, so that the air outlet of the smoke exhaust machine 6 can always correspond to the low end of the fixed frame 41.

[0071] The implementation principle of the active carbon collecting device in the embodiment of the application is as follows:

[0072] The exhaust fan 6 is used to exhaust the waste gas generated in the production process into the cabinet 1, and the waste gas is adsorbed by the activated carbon on the first guide plate 4. After the waste gas exhausted into the cabinet 1 is adsorbed by the activated carbon, only a small part of the waste gas not adsorbed by the activated carbon is discharged out of the cabinet 1 through the smoke outlet 8 for treatment, thereby greatly reducing the amount of waste gas that needs to be treated subsequently, thereby facilitating the reduction of the load of the subsequent waste gas treatment equipment and saving energy consumption.

[0073] The activated carbon on the first guide plate 4 is adsorbed after the waste gas is adsorbed and transported to the second guide plate 5, and the hot air fan 7 blows hot air at the second guide plate 5. The activated carbon after adsorption is subjected to temperature rising treatment by the blown hot air, and the activated carbon after temperature rising treatment is subjected to desorption, thereby enabling the activated carbon after adsorption to be desorbed in the first time for pretreatment, thereby facilitating the shortening of the time for the activated carbon to have a secondary adsorption effect, and greatly improving the efficiency of the repeated use of the activated carbon.

[0074] This kind of setting mode can optimize the activated carbon adsorption and desorption pretreatment steps, so that the activated carbon can be pretreated and collected in the first time after completing the action of adsorbing waste gas, thereby facilitating the significant improvement of the efficiency of the pretreatment between the activated carbon adsorption and desorption, and the efficiency of the activated carbon desorption pretreatment can be improved to timely perform the next waste gas adsorption, thereby facilitating the guarantee of the efficiency of the daily treatment of waste gas by the activated carbon.

[0075] As described above, the activated carbon is transported on the first guide plate 4 to adsorb the waste gas. The activated carbon after adsorption is transported to the second guide plate 5, and the transportation on the second guide plate 5 is a process of using the hot air fan 7 to pretreat the activated carbon for desorption. The activated carbon adsorption and desorption pretreatment is concentrated in one device by using the cabinet 1, effectively shortening the interval time between the activated carbon adsorption and desorption pretreatment, and greatly improving the efficiency of the repeated use of the activated carbon.

[0076] The above are the preferred embodiments of the present application, which do not limit the protection scope of the present application, therefore: any equivalent changes made on the structure, shape, principle of the present application shall be covered within the protection scope of the present application.
