Description

Technical Field

[0001] This utility model relates to the field of waste gas treatment technology, specifically to a two-stage activated carbon adsorption device for core-making waste gas. Background Technology

[0002] To reduce air pollution, waste gas generated during production needs to be purified before being emitted. Activated carbon adsorption devices are commonly used waste gas treatment devices, which have the advantages of being easy to use, having a large waste gas treatment capacity, low energy consumption, and wide applicability.

[0003] Traditional activated carbon adsorption devices have two problems. First, when replacing activated carbon adsorption plates that have lost their ability to purify properly after long-term use, it is necessary to stop supplying waste gas to the adsorption device, which is not conducive to ensuring waste gas treatment efficiency. Second, as the amount of solid impurities in the waste gas accumulates on the surface of the activated carbon adsorption plates, the risk of solid impurities clogging the activated carbon adsorption plates increases. Clogged activated carbon adsorption plates cannot allow waste gas to pass through smoothly, reducing the usable time of the activated carbon adsorption plates. Utility Model Content

[0004] The purpose of this invention is to provide a two-stage activated carbon adsorption device for core-making waste gas, which has the functions of not needing to stop gas supply when replacing activated carbon adsorption plates and being able to clean solid impurities on the surface of activated carbon adsorption plates.

[0005] The technical solution of this utility model is as follows:

[0006] A two-stage activated carbon adsorption device for core-making waste gas includes an adsorption box. The adsorption box has an inlet and an outlet at its left and right ends, respectively. The middle section of the adsorption box is divided into two air passages by a vertical plate. Each air passage has a baffle at its left and right ends, with several horizontally connected air vents evenly distributed from top to bottom. The air vents of adjacent baffles are staggered in height. Each of the left and right ends of the adsorption box has a blocking plate on the outer side of the baffle, with the inner surface of the blocking plate abutting against the outer surface of the baffle. The blocking plate has ventilation openings corresponding to the air vents. A lifting assembly connected to the blocking plate is provided inside the adsorption box, and the lifting assembly adjusts the blocking plate... The height of the plate is adjusted by controlling the overlap between the ventilation openings of the baffle plate and the air inlets of the baffle plate to change the opening and closing state of the air passage ports. Each of the two air passages is provided with two pairs of mounting seats, and an activated carbon adsorption plate is installed between each pair of mounting seats. The activated carbon adsorption plate is higher on the left and lower on the right. Inside the adsorption box, a cleaning component is provided on the left side of the activated carbon adsorption plate. The cleaning component slides against the left side of the activated carbon adsorption plate. At the bottom of the adsorption box, below the cleaning component, there is a waste collection trough. The bottom of the waste collection trough has a waste removal port, and a sealing door is hinged to the waste removal port. The front and rear sides of the adsorption box have mounting ports corresponding to each pair of mounting seats, and safety doors are detachably connected to the mounting ports.

[0007] Preferably, the lifting assembly includes a support frame, a telescopic rod, and a connecting rod. The top of the adsorption box is provided with a support frame, and the support frame is provided with a telescopic rod in the vertical direction. The movable part of the telescopic rod is coaxially connected to the connecting rod, and the lower end of the connecting rod passes into the adsorption box and is connected to the top of the blocking plate.

[0008] Preferably, the adsorption box has support columns at both the left and right ends, the support columns have vertical grooves, and the blocking plate has a slider that is slidably connected to the grooves.

[0009] Preferably, the cleaning assembly includes a motor, a docking rod, a threaded rod, a moving plate, a sliding rod, a sliding sleeve, a support rod, and a cleaning brush. Inside the adsorption box, a threaded rod is rotatably connected to the left side of the activated carbon adsorption plate. The threaded rod is in a vertical plane and parallel to the activated carbon adsorption plate. The upper end of the threaded rod is coaxially connected to the lower end of the docking rod. A motor is located at the top of the adsorption box, and the motor's drive rod is coaxially connected to the upper end of the docking rod. The moving plate has a cleaning brush that abuts against the left side of the activated carbon adsorption plate. The moving plate has a threaded through hole, which is threadedly connected to the threaded rod. The front and rear ends of the support rod are connected to the front and rear inner walls of the air passage. A sliding rod parallel to the threaded rod is provided on the support rod, and a sliding sleeve is slidably connected to the sliding rod. The sliding sleeve is connected to the moving plate.

[0010] Preferably, the cleaning brush has an insertion port on its back, and the movable plate has an insertion rod corresponding to the insertion port. The insertion port and the insertion rod are slidably connected. A spring is provided between the back of the cleaning brush and the movable plate. The bottom of the insertion port and the end of the insertion rod each have corresponding buckles and slots. When the buckle is engaged in the slot, the cleaning brush separates from the left side of the activated carbon adsorption plate. The upper and lower ends of the cleaning brush each have inclined grooves. The mounting bases on the upper and lower sides each have inclined blocks corresponding to the inclined grooves. When the cleaning brush rises to the point where the upper inclined block is pushed into the upper inclined groove, the cleaning brush moves away from the movable plate. When the cleaning brush descends to the point where the lower inclined block is pushed into the lower inclined groove, the cleaning brush moves towards the movable plate.

[0011] Preferably, the safety door and the installation opening are provided with corresponding latches at the closing point, and the safety door is provided with a handle.

[0012] Preferably, the bottom of the adsorption box is uniformly provided with support platforms.

[0013] The beneficial technical effects of this utility model are as follows:

[0014] 1. By using a combination of lifting components, blocking plates, and baffles, the opening and closing states of the two ventilation channels can be controlled. When the activated carbon adsorption plate in the ventilation channel under use is severely blocked, affecting the smooth passage of exhaust gas, the blocked ventilation channel can be closed and the other ventilation channel can be opened simultaneously. The exhaust gas can be treated in the newly opened ventilation channel. At the same time, the staff can replace the activated carbon adsorption plate in the closed ventilation channel through the installation port without stopping the gas supply, ensuring that the exhaust gas treatment can continue.

[0015] 2. The cleaning component cleans the side of the activated carbon adsorption plate facing the air inlet, thereby reducing the speed at which impurities clog the activated carbon adsorption plate, reducing the risk of clogging, and extending the service life.

Detailed Implementation

[0026] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0027] Example:

[0028] like Figures 1 to 8 As shown, this embodiment provides a two-stage activated carbon adsorption device for core-making waste gas, including an adsorption box 1. The adsorption box 1 has an air inlet 2 and an air outlet 3 at its left and right ends, respectively. The middle section of the adsorption box 1 is divided into two air passages 5 by a vertical plate 4. Each of the two air passages 5 has a baffle 6 at its left and right ends. The baffle 6 has several horizontally connected air vents 7 evenly distributed from top to bottom. The air vents 7 of adjacent baffles 6 are staggered in height. Each of the left and right ends of the adsorption box 1 has a blocking plate 8 on the outer side of the baffle 6. The inner surface of the blocking plate 8 is in contact with the outer surface of the baffle 6. The blocking plate 8 has ventilation openings 9 corresponding to the air vents 7. The adsorption box 1 has a lifting assembly 10 connected to the blocking plate 8, which adjusts the height of the blocking plate 8. The opening and closing state of the air passage 5 is changed by controlling the overlap between the ventilation opening 9 of the baffle 8 and the air inlet 7 of the baffle 6. Each of the two air passages 5 is provided with two pairs of mounting seats 11, and an activated carbon adsorption plate 12 is installed between each pair of mounting seats 11. The activated carbon adsorption plate 12 is higher on the left and lower on the right. Inside the adsorption box 1, a cleaning component 13 is provided on the left side of the activated carbon adsorption plate 12. The cleaning component 13 slides against the left side of the activated carbon adsorption plate 12. The bottom of the adsorption box 1 is provided with a waste collection trough 14 below the cleaning component 13. The bottom of the waste collection trough 14 is provided with a waste removal port 15. A sealing door 16 is hinged on the waste removal port 15. The front and rear sides of the adsorption box 1 are provided with mounting ports 17 corresponding to each pair of mounting seats 11. A safety door 18 is detachably connected to the mounting port 17.

[0029] The lifting assembly 10, the blocking plate 8, and the baffle 6 work together to control the opening and closing of the two ventilation channels 5. When the activated carbon adsorption plate 12 in the ventilation channel 5 is severely blocked, affecting the smooth passage of exhaust gas, the blocked ventilation channel 5 can be closed and the other ventilation channel 5 can be opened simultaneously. The exhaust gas can be treated in the newly opened ventilation channel 5. At the same time, the staff can replace the activated carbon adsorption plate 12 in the closed ventilation channel 5 through the installation port 17 without stopping the gas supply, ensuring that the exhaust gas treatment can continue. The cleaning assembly 13 cleans the side of the activated carbon adsorption plate 12 facing the air inlet, thereby reducing the speed at which impurities block the activated carbon adsorption plate 12, reducing the risk of blockage, and extending the service life. The cleaned impurities fall into the waste collection tank 14 below, and the staff can remove the accumulated impurities from the adsorption box 1 through the waste removal port 15, making cleaning convenient.

[0030] Furthermore, the lifting assembly 10 includes a support frame 19, a telescopic rod 20, and a connecting rod 21. The top of the adsorption box 1 is provided with a support frame 19, and the support frame 19 is provided with a telescopic rod 20 in the vertical direction. The movable rod of the telescopic rod 20 is coaxially connected to the connecting rod 21, and the lower end of the connecting rod 21 passes into the adsorption box 1 and is connected to the top of the blocking plate 8.

[0031] By adjusting the extension length of the movable rod of the telescopic rod 20, the height of the indirectly connected blocking plate 8 is changed, thereby adjusting the overlap between the vent 9 and the air inlet 7, and thus controlling the opening and closing state of the air inlet 5.

[0032] Furthermore, the adsorption box 1 has support columns 22 at both the left and right ends, and the support columns 22 have vertical grooves 23. The blocking plate 8 has a slider 24 that is slidably connected to the grooves 23.

[0033] The support column 22 can support the internal structure of the adsorption box 1. By using the sliding groove 23 and the slider 24 together, the movement direction of the block plate 8 connected to the slider 24 can be restricted, thereby improving the stability of the block plate 8 in its lifting and lowering activities.

[0034] Furthermore, the cleaning component 13 includes a motor 25, a docking rod 26, a threaded rod 27, a moving plate 28, a sliding rod 29, a sliding sleeve 30, a support rod 31, and a cleaning brush 32. Inside the adsorption box 1, a threaded rod 27 is rotatably connected to the left side of the activated carbon adsorption plate 12. The threaded rod 27 is in a vertical plane and parallel to the activated carbon adsorption plate 12. The upper end of the threaded rod 27 is coaxially connected to the lower end of the docking rod 26. A motor 25 is located at the top of the adsorption box 1. The motor 25 drives... The moving rod and the upper end of the docking rod 26 are coaxially connected. The moving plate 28 is provided with a cleaning brush 32 that abuts against the left side of the activated carbon adsorption plate 12. The moving plate 28 is provided with a threaded through hole 33, which is threadedly connected to the threaded rod 27. The front and rear ends of the support rod 31 are connected to the front and rear inner walls of the air passage 5. The support rod 31 is provided with a sliding rod 29 that is parallel to the threaded rod 27. A sliding sleeve 30 is slidably connected to the sliding rod 29, and the sliding sleeve 30 is connected to the moving plate 28.

[0035] By using the sliding sleeve 30 and the sliding rod 29 together, the moving direction of the movable plate 28 connected to the sliding sleeve 30 and the ability of the movable plate 28 to rotate with the rotation of the threaded rod 27 are restricted. The motor 25 drives the threaded rod 27 to rotate via the docking rod 26. The rotating threaded rod 27 drives the movable plate 28 connected to it to move along the axial direction of the threaded rod 27. The cleaning brush 32 connected to the movable plate 28 also moves accordingly. The reciprocating cleaning brush 32 brushes over the left side of the activated carbon adsorption plate 12 and brushes off the impurities adhering to it.

[0036] Furthermore, the cleaning brush 32 has an insertion port 34 on its back, and the moving plate 28 has an insertion rod 35 corresponding to the insertion port 34. The insertion port 34 and the insertion rod 35 are slidably connected. A spring 36 is provided between the back of the cleaning brush 32 and the moving plate 28. The bottom of the insertion port 34 and the end of the insertion rod 35 are respectively provided with corresponding buckles 37 and slots 38. When the buckle 37 is engaged in the slot 38, the cleaning brush 32 is separated from the left side of the activated carbon adsorption plate 12. The upper and lower ends of the cleaning brush 32 are each provided with inclined grooves 42. The mounting bases 11 on the upper and lower sides are each provided with inclined blocks 43 corresponding to the inclined grooves 42. When the cleaning brush 32 rises to push the upper inclined block 43 into the upper inclined groove 42, the cleaning brush 32 moves away from the moving plate 28. When the cleaning brush 32 falls to push the lower inclined block 43 into the lower inclined groove 42, the cleaning brush 32 moves towards the moving plate 28.

[0037] The cleaning brush 32 reciprocates along the axial direction of the threaded rod 27. When the cleaning brush 32 reaches its highest point, under the combined action of the upper inclined block 43 and the upper inclined groove 42, the cleaning brush 32 moves away from the moving plate 28 until the latch 37 disengages from the groove 38. Under the action of the spring 36, the cleaning brush 32 presses against the activated carbon adsorption plate 12. As the cleaning brush 32 moves from the highest point to the lowest point, under the action of the spring 36, the cleaning brush 32 abuts against the activated carbon adsorption plate 12, and the cleaning brush 32 brushes off impurities downwards. When the cleaning brush 32 reaches its lowest point, under the action of the lower inclined block 43, the cleaning brush 32 moves away from the moving plate 28 until the latch 37 disengages from the groove 38. With the combined action of block 43 and the inclined groove 42 at the lower end, the cleaning brush 32 moves towards the moving plate 28 until the buckle 37 engages with the slot 38, and the cleaning brush 32 separates from the activated carbon adsorption plate 12. During the process of the cleaning brush 32 moving from the lowest point to the highest point, the buckle 37 and the slot 38 fix the cleaning brush 32, so that the cleaning brush 32 does not come into contact with the activated carbon adsorption plate 12. This can prevent the cleaning brush 32 from brushing impurities upward when it moves upward, thereby reducing the scattering range of impurities and allowing the impurities to be better concentrated and fall into the waste collection tank 14, which is convenient for the staff to clean up afterwards.

[0038] Furthermore, the safety door 18 and the mounting port 17 are provided with corresponding latches 39 at the closing point, and the safety door 18 is provided with a handle 40.

[0039] The latch 39 is easy to unlock, and the handle 40 makes it easy for staff to lift and put down the safety door 18.

[0040] Furthermore, the bottom of the adsorption box 1 is uniformly provided with support platforms 41.

[0041] The adsorption box 1 is lifted by the support platform 41, leaving space for cleaning the waste collection tank 14 from the waste removal port 15.

[0042] Working principle and usage process of this utility model:

[0043] The staff changes the height of the blocking plate 8 by operating the lifting component 10, opening both the left and right ports of the air passage 5 on one side. At the same time, the left and right ports of the air passage 5 on the other side are closed simultaneously. The waste gas to be treated is introduced into the adsorption box 1 from the air inlet 2. The waste gas enters the opened air passage 5 and undergoes secondary adsorption by the two activated carbon adsorption plates 12. Finally, the treated waste gas leaves the adsorption box 1 from the air outlet 3. The cleaning component 13 of the air passage 5 that introduces the waste gas is turned on, and the impurities on the side of the activated carbon adsorption plate 12 facing the air inlet direction are brushed off. The brushed-off impurities fall into the waste collection tank 14.

[0044] When the purification capacity of the activated carbon adsorption plate 12 in the opened air passage 5 is insufficient, the staff operates the lifting component 10 to open the air passage 5 on the other side, and the previously used air passage 5 closes simultaneously. The exhaust gas then passes through the air passage 5 on the other side. The cleaning component of the newly opened air passage 5 is then opened, and the two activated carbon adsorption plates 12 in the closed air passage 5 are replaced.

[0045] When cleaning the waste collection tank 14 afterwards, open the sealed door 16 and clean the impurities accumulated in the waste collection tank 14 out of the adsorption box 1 through the waste removal port 15.

[0046] The above are merely specific application examples of this utility model and do not constitute any limitation on the scope of protection of this utility model. All technical solutions formed by equivalent transformations or equivalent substitutions fall within the scope of protection of this utility model.
