[0014] As a preferred technical solution of the present invention, the pre-filter cartridge and the high-efficiency filter cartridge are both cylinders.

[0015] The beneficial effects of the present invention are: 1. This kind of mobile activated carbon iodine adsorber loading and unloading unit is coordinated with a vehicle frame, a pre-filter cartridge, a high-efficiency filter cartridge, a pre-filter assembly, a high-efficiency filter, a high-pressure fan, and a cyclone dust removal assembly. When in use, after starting the high-pressure fan, the activated carbon is separated from the inside of the type III iodine adsorber, and then the activated carbon dust is initially removed by the cyclone dust collector, thereby maximizing the overall filtering effect of the device while helping to reduce the filtering burden of the subsequent pre-filter assembly and the high-efficiency filter. Then the airflow enters the pre-filter cartridge, and then enters the filter bag through the air inlet, and is discharged to the outside of the filter bag after being filtered by the filter bag. In this process, due to the action of air pressure, the upper fixed cover, the sliding frame and the sliding sleeve move upward, and the filter bag is unfolded. When the high-pressure fan is turned off, the upper fixed cover, the sliding frame and the sliding sleeve fall naturally due to the loss of air pressure. Since the high-pressure fan needs to be frequently started intermittently during use, the filter bag will continuously switch between the contracted and unfolded states, thereby peeling off part of the activated carbon dust attached to the surface of the filter bag, thereby further reducing the running resistance of the pre-filter and increasing the service life of the pre-filter. 2. This kind of mobile activated carbon iodine adsorber loading and unloading unit cooperates with the support frame, support pad, filter sealing pad, rotating rod, rotating drum, limiting slide groove, limiting slide bar, slot, lower brush, upper brush and driving blade. When the high-pressure fan is turned on, the airflow enters the filter bag through the air inlet, and the upper fixed cover, sliding frame and sliding sleeve move upward along the support rod to unfold the filter bag. At the same time, the rotating drum follows the upper fixed cover and the limiting slide groove to move upward along the limiting slide bar. The driving blade located at the bottom end of the outer wall of the rotating rod starts to rotate under the impetus of the airflow and drives the rotating rod to rotate accordingly. Due to the limiting effect of the limiting slide bar and the limiting slide groove, the rotating drum rotates synchronously with the rotating rod. In this process, the upper brush and the lower brush clean the filter bag at the same time, thereby further reducing the adhesion of activated carbon dust on the surface of the filter bag and increasing the service life of the pre-filter. 3. This type of mobile activated carbon iodine adsorber loading and unloading unit, by setting the pre-filter cartridge and the high-efficiency filter cartridge as cylinders, when the high-pressure fan is running, the pre-filter cartridge and the high-efficiency filter cartridge need to bear a large negative pressure (about 20000~35000Pa negative pressure). In the prior art, the pre-filter cartridge and the high-efficiency filter cartridge both adopt a square cylinder structure, so the tube wall thickness needs to be greater than 3mm, and reinforcing ribs are set inside to ensure the pressure bearing capacity of the pre-filter cartridge and the high-efficiency filter cartridge. By setting the pre-filter cartridge and the high-efficiency filter cartridge as cylinders, since the pressure bearing capacity of the cylindrical shell is much higher than that of the square cylindrical shell, the shell plate of 1.5~2mm can meet its pressure bearing requirements, thereby reducing the overall weight of the device as much as possible; 4. This type of mobile activated carbon iodine adsorber loading and unloading unit can further reduce the overall weight of the device without affecting the pressure-bearing effect of the pre-filter cartridge and the high-efficiency filter cartridge through the setting of hollow holes.

[0018] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0019] Reference Figure 1 , Figure 2 and Figure 3 The present invention discloses a mobile activated carbon iodine adsorber loading and unloading unit, comprising a vehicle frame 1, a pre-filter cartridge 2 arranged on one side of the top of the vehicle frame 1, a high-efficiency filter cartridge 3 arranged on one side of the top of the vehicle frame 1 away from the pre-filter cartridge 2 and connected to the pre-filter cartridge 2, a pre-filter assembly 4 arranged in the pre-filter cartridge 2, a high-efficiency filter 5 arranged in the high-efficiency filter cartridge 3, a first cover plate 6 for sealing the pre-filter cartridge 2, and a second cover plate 7 for sealing the high-efficiency filter cartridge 3, and an air outlet pipe 27 connected to the output end of a high-pressure blower 8 is fixedly connected to one side of the outer side wall of the vehicle frame 1; A high-pressure fan 8 connected to the bottom of the high-efficiency filter cartridge 3 is fixedly installed on one side of the inner bottom wall of the vehicle body frame 1. The pre-filter cartridge 2 and the high-efficiency filter cartridge 3 are both cylinders. When the high-pressure fan 8 is running, the pre-filter cartridge 2 and the high-efficiency filter cartridge 3 need to bear a large negative pressure (about 20,000~35,000Pa negative pressure). In the prior art, the pre-filter cartridge 2 and the high-efficiency filter cartridge 3 both adopt a square cylinder structure, so the tube wall thickness needs to be greater than 3mm, and reinforcing ribs are arranged inside to ensure the pressure-bearing capacity of the pre-filter cartridge 2 and the high-efficiency filter cartridge 3. By setting the pre-filter cartridge 2 and the high-efficiency filter cartridge 3 as cylinders, since the pressure-bearing capacity of the cylindrical shell is much higher than that of the square cylindrical shell, a shell plate of 1.5~2mm can meet its pressure-bearing requirements, thereby minimizing the overall weight of the device.

[0020] Reference Figure 1 , Figure 2 and Figure 3 The bottom of the pre-filter cartridge 2 is provided with a cyclone dust removal assembly 9 connected to the pre-filter cartridge 2, and universal wheels 22 are provided at the four corners of the lower surface of the vehicle frame 1, and a moving handle 23 is fixedly connected to the side of the outer wall of the vehicle frame 1 away from the air inlet pipe 95; When the staff needs to move the vehicle frame 1, they can push and pull the vehicle frame 1 by moving the handle 23, so that the vehicle frame 1 can be moved through the universal wheel 22. The outer wall of the vehicle frame 1 is evenly provided with hollow holes 24. By setting the hollow holes 24, the weight of the vehicle frame 1 can be reduced as much as possible, thereby further reducing the weight of the entire device; The cyclone dust removal assembly 9 includes a conical shell 91 fixedly connected to the bottom of the pre-filter cartridge 2, a communication port 92 opened at the center of the inner bottom wall of the pre-filter cartridge 2, an exhaust pipe 93 fixedly connected to the bottom of the pre-filter cartridge 2 and located around the communication port 92, and a dust collecting bucket 94 fixedly installed at the bottom of the conical shell 91. An air inlet pipe 95 connected to the conical shell 91 is fixedly connected to one side of the outer wall of the conical shell 91. When the high-pressure blower 8 is started, the activated carbon leaves the interior of the Type III iodine adsorber and first enters the conical outer shell 91 through the air inlet pipe 95. At the same time, a rotating airflow from top to bottom is formed inside the conical outer shell. Under the action of the internal rotating airflow, the activated carbon dust is thrown to the inner wall of the conical outer shell 91 under the action of centrifugal force, and then falls into the dust collecting bucket 94 at the bottom through the connecting port 92. The gas from which the activated carbon dust is initially removed can flow upward through the exhaust pipe 93 and the connecting port 92 into the pre-filter cartridge 2, and is further filtered through the pre-filter component 4, thereby helping to reduce the filtering burden of the subsequent pre-filter component 4 and the high-efficiency filter 5 while maximizing the overall filtering effect of the device.

[0021] Reference Figure 3 , Figure 4 and Figure 5 The pre-filter assembly 4 includes a bottom plate 41, support rods 42 fixedly connected to the upper surface of the bottom plate 41 and distributed in an annular shape, and a top plate 43 fixedly connected to the top of the support rods 42. The bottom plate 41 is evenly provided with air inlets 44 distributed in an annular shape. The bottom of the bottom plate 41 is fixedly connected to a support frame 11, and the bottom of the support frame 11 is fixedly connected to a support pad 12 distributed in an annular shape. By setting the support frame 11 and the support pad 12, the support pad 12 and the support frame 11 can support the bottom plate 41, so that there is a space between the bottom plate 41 and the inner bottom wall of the pre-filter cartridge 2 that allows airflow to circulate and enter the air inlet 44. The bottom plate 41 is fixedly connected with a filter sealing pad 13 around the lower surface. By setting the filter sealing pad 13, the air tightness between the lower surface of the bottom plate 41 and the inner bottom wall of the pre-filter cartridge 2 can be ensured, so as to try to ensure that the airflow can only flow upward through the air inlet 44 after entering the pre-filter cartridge 2 through the connecting port 92, so as to ensure that the airflow flows according to the predetermined path; A lower fixed ring 45 is fixedly connected to the upper surface of the bottom plate 41 around the air inlet 44, a sliding sleeve 46 is slidably connected to the support rod 42, a sliding frame 47 is fixedly connected to the outer wall of the sliding sleeve 46, and an upper fixed cover 48 distributed in a ring is fixedly connected to the lower surface of the sliding frame 47 around, and a filter bag 49 is arranged between the lower fixed ring 45 and the upper fixed cover 48; The two ends of the filter bag 49 are respectively fixedly connected to the lower fixing ring 45 and the upper fixing cover 48 by throat clamps. When the airflow passes through the connecting port 92 and the air inlet 44, it enters the interior of the filter bag 49 located at the lower fixing ring 45 and the upper fixing cover 48, and is discharged to the outside of the filter bag 49 after being filtered by the filter bag 49. In the process of the airflow passing through the filter bag 49 for filtering, due to the effect of air pressure, the upper fixing cover 48, the sliding frame 47 and the sliding sleeve 46 will move upward along the support rod 42 and expand the filter bag 49, thereby increasing the filtering area of ​​the filter bag 49 and maximizing the filtering efficiency of the airflow passing through the filter bag 49 for filtering. When the high-pressure fan 8 is turned off, due to the loss of air pressure, the upper fixing cover 48, the sliding frame 47 and the sliding sleeve 46 will naturally fall along the support rod 42 again. Since the high-pressure fan 8 needs to be frequently started and stopped during use, the filter bag 49 will continuously switch between the contracted and expanded states, thereby peeling off part of the activated carbon dust attached to the surface of the filter bag 49, thereby minimizing the operating resistance of the pre-filter and increasing the service life of the pre-filter.

[0022] Reference Figure 1 and Figure 2 The upper surface of the vehicle body frame 1 is provided with a clamping assembly 10 for making the first cover plate 6 and the second cover plate 7 closely fit the vehicle body frame 1. The lower surfaces of the first cover plate 6 and the second cover plate 7 are fixedly connected with external sealing gaskets 25 all around. The external sealing gaskets 25 can maximize the airtightness between the first cover plate 6 and the second cover plate 7 when they are closely fitted to the vehicle body frame 1. The upper surfaces of the first cover plate 6 and the second cover plate 7 are fixedly connected with lifting handles 26. The clamping assembly 10 includes a bolt 101 fixedly connected to the upper surface of the vehicle frame 1 and located around the pre-filter cartridge 2 and the high-efficiency filter cartridge 3, a collar 102 is sleeved on the bolt 101, a pressing tongue 103 is fixedly connected to one side of the outer wall of the collar 102, a nut 104 is threadedly connected to the bolt 101 above the collar 102, and a gasket 105 is provided on the outer wall of the bolt 101 between the nut 104 and the collar 102; When the pre-filter cartridge 2 and the high-efficiency filter cartridge 3 need to be sealed by the first cover plate 6 and the second cover plate 7, the nut 104 is first rotated to move the nut 104 to the side away from the collar 102 until the nut 104 is completely out of contact with the gasket 105, and then the collar 102 is rotated until the tongue 103 is away from the pre-filter cartridge 2 and the high-efficiency filter cartridge 3, and then the first cover plate 6 and the second cover plate 7 are placed at the position where the pre-filter cartridge 2 and the high-efficiency filter cartridge 3 are sealed; After placement is completed, the ring 102 is rotated again until the pressing tongue 103 is close to the first cover plate 6 and the second cover plate 7, and the nut 104 is screwed again until the nut 104 and the gasket 105 press the ring 102, so that the pressing tongue 103 presses the first cover plate 6 and the second cover plate 7. At the same time, the first cover plate 6 and the second cover plate 7 that are tightly fitted to the vehicle body frame 1 can press the pre-filter component 4 in the pre-filter cartridge 2 and the high-efficiency filter 5 in the high-efficiency filter cartridge 3, thereby minimizing the stability of the pre-filter component 4 and the high-efficiency filter 5 during use and the airtightness between the pre-filter component 4 and the inner bottom wall of the pre-filter cartridge 2, and between the high-efficiency filter 5 and the inner bottom wall of the high-efficiency filter cartridge 3.

[0023] Reference Figure 5 , Figure 6 and Figure 7 , the upper surface of the support frame 11 is located in the air inlet 44 and is rotatably connected to a rotating rod 14, the center of the inner top wall of the upper fixed cover 48 is rotatably connected to a rotating drum 15, both sides of the inner side wall of the rotating drum 15 are provided with limited sliding grooves 16, both sides of the outer side wall of the rotating rod 14 are fixedly connected with limited sliding strips 17 adapted to the limited sliding grooves 16, and the rotating drum 15 is provided with grooves 18 on both sides away from the limited sliding grooves 16, and the outer side wall of the rotating rod 14 is provided with lower brushes 19 on both sides close to the grooves 18, and the outer side wall of the rotating drum 15 is provided with upper brushes 20 on both sides away from the grooves 18, and the bottom end of the outer side wall of the rotating rod 14 is fixedly connected with a driving blade 21; When the high-pressure fan 8 is turned on, the airflow enters the filter bag 49 through the air inlet 44, and while the upper fixed cover 48, the sliding frame 47 and the sliding sleeve 46 move upward along the support rod 42 to unfold the filter bag 49, the rotating drum 15 follows the upper fixed cover 48 and the limiting slide groove 16 to move upward along the limiting slide bar 17, and the driving fan blade 21 located at the bottom end of the outer wall of the rotating rod 14 starts to rotate under the push of the airflow, and drives the rotating rod 14 to rotate accordingly. Due to the limiting effect of the limiting slide bar 17 and the limiting slide groove 16, the rotating drum 15 rotates synchronously with the rotating rod 14. In this process, the upper brush 20 and the lower brush 19 clean the filter bag 49 at the same time, thereby further reducing the adhesion of activated carbon dust on the surface of the filter bag 49.

[0024] The working principle of the present invention is: When the type III iodine adsorber needs to be unloaded, the staff can first push and pull the body frame 1 by moving the handle 23, so that the body frame 1 moves through the universal wheel 22. When the body frame 1 moves to the working position, the air inlet pipe 95 is connected to the discharge port of the type III iodine adsorber, and then the high-pressure blower 8 is started. When the high-pressure blower 8 is started, the activated carbon is separated from the inside of the type III iodine adsorber and first enters the conical shell 91 through the air inlet pipe 95, and a rotating airflow from top to bottom is formed inside the conical shell; Under the action of the internal rotating airflow, the activated carbon dust is thrown toward the inner wall of the conical shell 91 under the action of centrifugal force, and then falls into the dust collecting bucket 94 at the bottom through the connecting port 92. The gas that has initially removed the activated carbon dust can flow upward into the pre-filter cartridge 2 through the exhaust pipe 93 and the connecting port 92, and is further filtered through the pre-filter component 4, thereby helping to reduce the filtering burden of the subsequent pre-filter component 4 and the high-efficiency filter 5 while maximizing the overall filtering effect of the device; After passing through the connecting port 92 and the exhaust pipe 93, the airflow first flows into the space between the support frame 11 and the inner bottom wall of the pre-filter cartridge 2, and then enters the interior of the filter bag 49 located at the lower fixing ring 45 and the upper fixing cover 48 through the air inlet 44, and is discharged to the outside of the filter bag 49 after being filtered by the filter bag 49. In the process of the airflow passing through the filter bag 49 for filtering, due to the effect of air pressure, the upper fixing cover 48, the sliding frame 47 and the sliding sleeve 46 will move upward along the support rod 42 and expand the filter bag 49, thereby increasing the filtering area of ​​the filter bag 49 and maximizing the filtering efficiency of the airflow passing through the filter bag 49 for filtering; When the high-pressure fan 8 is turned off, due to the loss of air pressure, the upper fixed cover 48, the sliding frame 47 and the sliding sleeve 46 naturally fall down along the support rod 42 again. Since the high-pressure fan 8 needs to be frequently started and stopped during use, the filter bag 49 will continuously switch between the contracted and expanded states, thereby partially peeling off the activated carbon dust attached to the surface of the filter bag 49, thereby minimizing the running resistance of the pre-filter and increasing the service life of the pre-filter. At the same time, when the high-pressure fan 8 is turned on, the airflow enters the filter bag 49 through the air inlet 44, and while the upper fixed cover 48, the sliding frame 47 and the sliding sleeve 46 move upward along the support rod 42 and unfold the filter bag 49, the rotating drum 15 follows the upper fixed cover 48 and the limiting slide groove 16 to move upward along the limiting slide bar 17, and the driving fan blade 21 located at the bottom end of the outer wall of the rotating rod 14 starts to rotate under the impetus of the airflow, and drives the rotating rod 14 to rotate accordingly. Due to the limiting effect of the limiting slide bar 17 and the limiting slide groove 16, the rotating drum 15 rotates synchronously with the rotating rod 14. In this process, the upper brush 20 and the lower brush 19 clean the filter bag 49 at the same time, thereby further reducing the adhesion of activated carbon dust on the surface of the filter bag 49; After the airflow containing activated carbon dust is filtered by the pre-filter assembly 4, it flows into the high-efficiency filter cartridge 3, and after being filtered by the high-efficiency filter 5, it is discharged through the high-pressure fan 8 and the outlet pipe 27.
