Description

Technical Field

[0001] The present invention relates to the technical field of gas purification, and in particular to a gas purification method and device. Background Art

[0002] Gas purification is an important process that aims to remove impurities and harmful substances in the gas to obtain purer gas. This process plays an important role in many industrial fields and daily life. These gas purification technologies not only help to improve product quality and meet production standards, but also effectively protect the environment and ensure personal safety, and reduce the negative impact on the ecology. Among the many gas purification technologies, the adsorption method is highly favored due to its high efficiency and environmental protection. This method is based on a variety of adsorbents, such as activated carbon, silica gel and molecular sieves, and uses its surface and internal developed pore structure to show excellent adsorption capacity. The adsorbent can effectively capture and fix various impurities and harmful substances in the fluid, including organic gases, odors and particles, and is widely used in the air purification process.

[0003] After the existing gas purification device has been used for a period of time, the pollutants adsorbed on the surface of the adsorbent gradually increase, resulting in a significant decrease in its adsorption capacity. This process is called adsorption saturation, which makes the adsorbent unable to effectively capture and remove impurities and harmful substances in the gas, thereby affecting the efficiency and quality of gas purification. In order to maintain the normal operation and purification effect of the device, the adsorbent must be replaced or regenerated regularly. However, the service life of the adsorbent is closely related to the amount of impurities in the gas. When there are more impurities and harmful substances in the gas, the adsorbent will be adsorbed and saturated prematurely, resulting in untimely replacement of the adsorbent, which may further reduce the purification efficiency. Untreated harmful substances enter the process system and the environment, increasing the risk of environmental pollution and may cause equipment damage and safety hazards. Summary of the invention

[0004] The purpose of the present invention is to solve the problem that after the existing gas purification device has been used for a period of time, the pollutants adsorbed on the surface of the adsorbent gradually increase, resulting in a significant decrease in its adsorption capacity. This process is called adsorption saturation, which makes the adsorbent unable to effectively capture and remove impurities and harmful substances in the gas, thereby affecting the efficiency and quality of gas purification. In order to maintain the normal operation and purification effect of the device, the adsorbent must be replaced or regenerated regularly. However, the service life of the adsorbent is closely related to the amount of impurities in the gas. When there are more impurities and harmful substances in the gas, the adsorbent will be adsorbed and saturated in advance, resulting in untimely replacement of the adsorbent, which may further reduce the purification efficiency. Untreated harmful substances enter the process system and the environment, increasing the risk of environmental pollution and possibly causing damage to the equipment and safety hazards. A gas purification method and device are provided.

[0007] Among them, when the adsorbent in the adsorbent box is in an adsorption saturation state, the weight of the adsorbent reaches a maximum value. At this time, the adsorbent box presses down the push rod to shrink the spring until the bottom end of the adsorbent box is magnetically adsorbed and connected to the bottom end of the adjusting groove. At the same time, due to the downward movement of the push rod, it will contact the linkage block at the top of the limit groove and push the linkage block downward, causing the baffle to move downward in the installation groove and leak out the discharge port. At this time, the adsorbent in the adsorbent box is discharged through the discharge port.

[0009] As a further solution of the present invention: a feed box is fixedly connected to the upper end of the outer side of the outer barrel, one end of the feed pipe passes through the outer barrel and is connected with the feed box, a box cover is slidably connected to the top of the feed box, a waste box is fixedly connected to the lower end of the outer side of the outer barrel, the feed port and the discharge port of the waste box are connected, the bottom end of the waste box is also slidably connected to a box cover, the bottom end of the waste box is fixedly connected to a support seat, and the top end of the outer barrel is fixedly connected to a fan.

[0011] As a further solution of the present invention: the discharging device also includes a rotating column arranged in the feed pipe, the top of the rotating column is fixedly connected to a connecting rod, one end of the connecting rod passes through the feed pipe and is rotatably connected to the feed pipe, the outer side of the rotating column is fixedly connected to a stirring blade, the bottom end of the rotating column is provided with a slot, the top column is adapted to the slot, the inner wall of the slot is fixedly connected to a guide block, and the guide block is adapted to the guide groove.

[0012] As a further solution of the present invention: the anti-discharge device includes a mounting frame fixedly connected to the outer side of the feed pipe, a block is slidably inserted on the mounting frame, and two groups of blocks and mounting frames are arranged. The side ends of the two groups of blocks are provided with spring two, and the two ends of the spring two are respectively fixedly connected to the two groups of blocks.

[0013] As a further solution of the present invention: a push plate is fixedly connected to the bottom end of the stopper, a group of closing plates are slidably inserted into the corresponding surfaces of the stopper on both sides, and the corresponding surfaces of the two groups of closing plates are magnetically adsorbed.

[0014] A gas purification method comprises the following steps:

[0015] S1. First, the adsorbent box without adsorbent is lifted up by the lifting device, so that the adsorbent box is moved to the upper limit position of the adjusting tank. During the movement, the top column and the support plate at the top of the feed pipe of the adsorbent box activate and open the anti-discharge device, so that the feed pipe of the adsorbent box is fully inserted into the feed pipe, and enters the feeding state;

[0016] S2. Afterwards, as the top column enters the feed pipe and is inserted into the rotating column in the feed pipe, the rotating column is driven to rotate, so that the adsorbent in the feed box falls into the adsorbent box through the feed pipe. As the adsorbent gradually enters the adsorbent box, the weight of the adsorbent box gradually increases, causing the adsorbent box to press down on the lifting device. When the adsorbent box is filled with adsorbent, the adsorbent box moves to the middle position of the adjustment tank, causing the top column to fall off from the rotating column, and the anti-discharge device blocks the discharge port of the feed pipe again, entering the filtering state;

[0017] S3. Finally, start the fan at the top of the outer barrel to allow air to enter the outer barrel from bottom to top. When the air passes through the adsorbent box, the adsorbent in the adsorbent box absorbs and filters the impurities in the air, increasing its weight and gradually pressing down the lifting device. When the adsorbent is in an adsorption saturation state, the weight of the adsorbent and the adsorbent box causes the adsorbent box to move to the limit position at the bottom of the adjusting groove. At this time, the adsorbent box and the bottom of the adjusting groove produce magnetic adsorption, so that the adsorbent box remains in the current position, and as the lifting device moves downward, the baffle moves downward in the installation groove, exposing the discharge port, so that the adsorbent in the adsorbent box enters the waste box through the discharge port, and the device enters the discharge state.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. In the present invention, the height of the adsorbent box can be automatically adjusted according to the weight of the adsorbent in the adsorbent box through the synergistic effect of the push rod and the spring 1 in the lifting device. When the adsorbent is saturated, the weight of the adsorbent box increases, the push rod is pressed down, and the spring 1 contracts. When the adsorbent is discharged, the spring 1 recovers its original length and pushes the adsorbent box upward, ensuring that the adsorbent box is always at the optimal working height. The automatic opening and closing of the baffle is realized through the linkage of the push rod and the elastic rope. When the adsorbent box presses the push rod down, the baffle opens to allow the adsorbent to be discharged and automatically discharge. When the adsorbent box moves upward, the baffle closes to prevent the adsorbent from leaking. This automatic control system simplifies the operation process and improves the automation of the system.

[0020] 2. The present invention uses an anti-discharge device to ensure that when the adsorbent box leaves the feed pipe, the closing plate can move quickly and tightly close the stopper, thereby preventing the adsorbent from leaking from the feed pipe. This design enhances the sealing of the system and reduces the risk of adsorbent waste and environmental pollution. The push plate can automatically move outward under the action of the top column, so that the closing plate retracts into the stopper to keep the feed pipe unobstructed. This automatic control system reduces manual intervention and improves the convenience and efficiency of operation;

[0021] 3. In the present invention, the coordination of the cloth block and the feed hopper in the discharge device ensures that the adsorbent can be evenly distributed inside the adsorbent box when it is discharged from the feed pipe. This uniform distribution helps to improve the use efficiency of the adsorbent and the gas purification effect, and ensures that the airflow can fully contact the adsorbent when passing through it, so as to better remove impurities and harmful gases in the air. The rotating column rotates under the action of the top column, driving the stirring blades to rotate, driving the adsorbent in the feed pipe to slide downward and enter the feed hopper in the adsorbent box. This automatic stirring system ensures the fluidity and uniform distribution of the adsorbent, and avoids blockage or uneven distribution of the adsorbent in the feed pipe.

For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances. The following is an explanation of an embodiment of the present invention based on the overall structure of the present invention.

[0036] Reference Figures 1 to 7In an embodiment of the present invention, a gas purification method and device include: an outer barrel 1, an adjustment groove 11 is opened in the outer barrel 1, an adsorbent box 5 is slidably connected in the adjustment groove 11, the adsorbent box 5 is composed of two groups of conical upper and lower plates and a group of cylinders, the cylinder is arranged at the top of the conical upper plate, and penetrates the upper plate and the lower plate and is fixedly connected, and a feed port is opened through the side end of the cylinder between the conical upper and lower plates, and through holes for air to pass through are evenly opened on the conical upper and lower plates, the bottom end of the adsorbent box 5 and the bottom end of the inner part of the adjustment groove 11 are both embedded with magnetic blocks, and the corresponding surfaces of the two groups of circular magnetic blocks are of different poles, and a height of the adsorbent box 5 is automatically adjusted in the outer barrel 1. The lifting device 6 is provided with multiple groups of lifting devices 6, which are evenly distributed in the outer barrel 1. A discharge port 12 is provided through the side end of the outer barrel 1. A support column is fixedly connected in the discharge port 12 to support the outer barrel 1 divided into upper and lower ends by the discharge port 12. The discharge port 12 is connected through the adjusting groove 11, and the bottom end of the discharge port 12 is flush with the top of the conical lower plate of the adsorbent box 5 as an inclined surface, so that the adsorbent can slide along the top of the conical lower plate of the adsorbent box 5 and the bottom end of the discharge port 12 to the outside of the outer barrel 1. A mounting groove 13 is provided in the discharge port 12, and a baffle 14 is slidably inserted in the mounting groove 13 to prevent the adsorbent in the adsorbent box 5 from being discharged from the discharge port 12;

[0037] The lifting device 6 includes a moving groove 61 opened at the bottom end of the adjusting groove 11, and a limiting groove 62 is opened at the bottom end of the moving groove 61. The limiting groove 62 is wide at the bottom and narrow at the top. The limiting groove 62 is connected with the moving groove 61 and the installation groove 13 respectively. A push rod 63 is slidably inserted in the moving groove 61. The top end of the push rod 63 abuts against the bottom end of the adsorbent box 5. The bottom end of the push rod 63 is fixedly connected with an elastic rope 64. One end of the elastic rope 64 is fixedly connected with a linkage block 65. The linkage block 65 is composed of a group of cylinders and a group of straight plates. One end of the straight plate is fixedly connected to the cylinder, and the other end passes through the limiting groove 62. and the mounting groove 13, which is fixedly connected with the baffle 14. The diameter of the cylinder is larger than the width of the top end of the limiting groove 62 and smaller than the width of the bottom end of the limiting groove 62. A spring 67 is arranged in the movable groove 61. One end of the spring 67 is fixedly connected with the bottom end of the push rod 63, and the other end of the spring 67 is fixedly connected with the bottom end inside the movable groove 61. The push rod 63 is composed of a group of upper rods and a group of lower rods. The diameter of the upper rod is smaller than the width of the movable groove 61 and larger than the width of the limiting groove 62. The diameter of the lower rod is smaller than the diameter of the limiting groove 62, so that the lower rod can be inserted into the limiting groove 62 to push the linkage block 65 to move.

[0038] Among them, when the adsorbent in the adsorbent box 5 is in the adsorption saturation state, the weight of the adsorbent reaches the maximum value. At this time, the adsorbent box 5 presses down the top rod 63 to shrink the spring 67 until the bottom end of the adsorbent box 5 is magnetically adsorbed and connected with the bottom end of the adjusting groove 11. At this time, the weight of the adsorbent box 5 plus the magnetic adsorption force of the magnet at the bottom end of the adsorbent box 5 and the bottom end of the adjusting groove 11 is greater than the elastic force of the spring 67, so that the adsorbent box 5 is restricted to the current state. At the same time, due to the downward movement of the top rod 63, it will contact the linkage block 65 at the top end of the limiting groove 62, and push the linkage block 65 to move downward, so that the baffle 14 moves downward in the installation groove 13, The discharge port 12 leaks out. At this time, the adsorbent in the adsorbent box 5 is discharged through the discharge port 12. When the adsorbent in the adsorbent box 5 is completely discharged, the weight of the adsorbent box 5 plus the magnetic adsorption force of the magnet at the bottom end of the adsorbent box 5 and the bottom end of the adjusting groove 11 is less than the elastic force of the spring 67, so that the spring 67 restores its original length and pushes the adsorbent box 5 upward, so that the adsorbent box 5 is moved to the top limit position of the adjusting groove 11. At the same time, as the spring 67 pushes the top rod 63 upward, the elastic rope 64 at the bottom end of the top rod 63 pulls the linkage block 65 upward, so that the linkage block 65 drives the baffle 14 to move upward, and the discharge port 12 is blocked again.

[0039] It is explained that in the present technical solution, the adsorbent filled in the adsorbent box 5 is a composite adsorbent, which is a material composed of two or more different adsorbent materials, and adsorbs impurities and harmful gases in the air, and absorbs moisture in the air. When the composite adsorbent is in an adsorption saturation state, its weight can increase rapidly relative to the initial state, so that it can press down the spring 67.

[0040] Reference Figures 1 to 5A feed pipe 4 is fixedly arranged in the outer barrel 1, and the feed pipe 4 is composed of multiple groups of connecting pipes, a group of connecting plates and a group of connecting frames. The multiple groups of connecting pipes are movably connected with the connecting plates, and the top of the connecting plates is fixedly connected with the connecting frame, and the connecting frame is fixedly connected with the top of the inner part of the outer barrel 1. A discharge device 8 is arranged on the feed pipe 4 to make the adsorbent flow into the adsorbent box 5, and an anti-discharge device 7 is arranged on the feed pipe 4 to block the discharge port of the feed pipe 4. A feed replenishment box 2 is fixedly connected to the upper end of the outer side of the outer barrel 1, and one end of the multiple groups of connecting pipes in the feed pipe 4 passes through the outer barrel 1 and is connected with the feed replenishment box 2. A box cover 21 is slidably connected to the top of the feed replenishment box 2, and a waste box 3 is fixedly connected to the lower end of the outer side of the outer barrel 1. The waste The feed port of the box 3 is through-connected with the discharge port 12, and the bottom end of the waste box 3 is also slidably connected with a box cover 21, and the bottom end of the waste box 3 is fixedly connected with a support seat 10. The top of the outer barrel 1 is through-opened with a plurality of groups of through holes for air to flow out, and each group of through holes is fixedly connected with a group of fans 9, and the bottom end of the outer barrel 1 is through-opened with through holes for air to flow into the outer barrel 1. When the fan 9 is started, the outside air enters the outer barrel 1 through the through holes at the bottom of the outer barrel 1 and moves upward. During the movement, the air passes through the through holes opened on the adsorbent box 5, contacts with the adsorbent in the adsorbent box 5, removes impurities, harmful gases and part of the moisture in the air, and is finally discharged through the through holes below the fan 9.

[0041] The above solution promotes the reloading of the adsorbent through the feed pipe 4 and ensures sufficient adsorption material during the gas purification process, thereby improving the overall utilization of the adsorbent and reducing the operating cost.

[0042] Reference Figures 8 to 11The discharge device 8 includes a cloth block 81 fixedly connected to the bottom end of the feed port of the adsorbent box 5. The cloth block 81 is conical, so that the fallen adsorbent contacts the conical surface and slides down for random distribution. A feed hopper 82 is arranged above the cloth block 81. The feed hopper 82 is in an inverted cone, so that the adsorbent discharged from the feed pipe 4 moves to the top of the cloth block 81 and falls, avoiding uneven distribution of the adsorbent. The feed hopper 82 is fixedly connected to the inner end of the feed port of the adsorbent box 5, and the top of the feed port of the adsorbent box 5 A support plate 83 is fixedly connected, the top of the support plate 83 is an arc surface, and the support plate 83 is provided with two groups, which are symmetrically distributed at the top of the feed port of the adsorbent box 5. A top column 84 is fixedly connected to the top of the support plate 83, and the top column 84 is composed of a group of cylinders and a group of cones. The cone is fixedly connected to the top of the cylinder. A guide groove 841 is opened at the side end of the top column 84, and the guide groove 841 is spiral. There are two groups of guide grooves 841, which are symmetrically distributed at the side ends of the cylinders in the top column 84. The discharge device 8 also includes a feed port provided at the feed port. The rotating column 85 in the tube 4, the top of the rotating column 85 is fixedly connected to a connecting rod 86, one end of the connecting rod 86 passes through the feed tube 4 and is rotatably connected to the feed tube 4, the outer side of the rotating column 85 is fixedly connected to a stirring blade 851, the stirring blade 851 is spiral, the bottom end of the rotating column 85 is provided with a slot 852, the top column 84 is adapted to the slot 852, the inner wall of the slot 852 is fixedly connected to a guide block 853, the guide block 853 is spiral, and two groups of guide blocks 853 are arranged, symmetrically distributed on the slot The inner wall of the groove 852 and the guide block 853 are adapted to the guide groove 841. When the top column 84 moves up, it is inserted into the slot 852. Under the action of the guide groove 841 and the guide block 853, the rotating column 85 is rotated, and the stirring blade 851 is driven to rotate. With the rotation of the stirring blade 851, the adsorbent in the feed pipe 4 is driven to slide downward and enter the feed hopper 82 in the adsorbent box 5. It is guided by the feed hopper 82 so that the adsorbent falls on the cloth block 81 and slides into the inside of the adsorbent box 5.

[0043] The above scheme is adopted: the cooperation between the cloth block 81 and the feed hopper 82 ensures that when the adsorbent is discharged from the feed pipe 4, it can be evenly distributed inside the adsorbent box 5. This uniform distribution helps to improve the use efficiency of the adsorbent and the gas purification effect, ensuring that the airflow can fully contact the adsorbent when passing through it, thereby better removing impurities and harmful gases in the air.

[0044] Reference Figure 10 to Figure 11The anti-discharging device 7 includes a mounting frame 71 fixedly connected to the outside of the feed pipe 4. The mounting frame 71 is provided with two groups, which are symmetrically distributed on the outside of the feed pipe 4. A stopper 72 is slidably inserted on each group of mounting frames 71. The side ends of the two groups of stoppers 72 are provided with springs 73. The two ends of the springs 73 are respectively fixedly connected to the two groups of stoppers 72. There are two groups of springs 73, which are symmetrically distributed on both sides of the stoppers 72. The bottom end of the stopper 72 is fixedly connected to a push plate 74. The push plate 74 is C-shaped. A ball is embedded at the bottom end of the push plate 74, and the ball is rotatably connected to the push plate 74. There are multiple groups of balls, which are evenly distributed on the push plate 74. At the bottom, a group of closing plates 75 are slidably inserted at the corresponding surfaces of the stoppers 72 on both sides, and a group of magnetic blocks are embedded in the corresponding surfaces of the two groups of closing plates 75. The corresponding surfaces of the two groups of magnetic blocks are of different poles. A group of C-shaped notches are opened at the corresponding surfaces of each group of closing plates 75. The C-shaped notches are adapted to the top column 84. When the top column 84 moves up, the conical surface at the top of the top column 84 abuts against the ball at the bottom end of the push plate 74, and pushes the two groups of push plates 74 to move outward, so that the spring 2 73 is stretched. When the two groups of push plates 74 are pushed open, the closing plates 75 therein are connected due to the adsorption of the magnetic blocks, so that the top column 84 is inserted into the C-shaped notch. As the movement continues, the arc surface at the top of the support plate 83 abuts against the ball at the bottom of the push plate 74, pushing the push plate 74 to continue to move outward. As the movement continues, the arc surface at the top of the support plate 83 abuts against the lower contour of the C-shaped notch of the closing plate 75, causing the two sets of closing plates 75 to retract into the stopper 72 until the width of the stopper 72 is the same as the diameter of the feed cylinder in the adsorbent box 5, so that the feed cylinder in the adsorbent box 5 is inserted into the feed pipe 4. As the adsorbent in the adsorbent box 5 increases, the weight of the adsorbent box 5 continues to increase, causing the adsorbent box 5 to push the top rod 63 downward until the adsorbent box 5 moves to The middle position of the adjustment groove 11, during the movement, the top column 84 and the feed cylinder in the adsorbent box 5 gradually withdraw from the feed pipe 4. When the feed cylinder in the adsorbent box 5 withdraws first, the block 72 gradually closes under the action of the spring 73 until the block 72 abuts against the side end of the top column 84. At this time, under the action of the magnetic block, the two groups of closing plates 75 move toward each other until they abut, so that the feed cylinder in the adsorbent box 5 moves out of the feed pipe 4, while the top column 84 continues to remain in the feed pipe 4. Finally, with the withdrawal of the top column 84 and under the action of its top cone, the block 72 gradually closes and enters a closed state.

[0045] The above solution is adopted: the combination of the closing plate 75 and the magnetic block ensures that when the adsorbent box 5 leaves the feed pipe 4, the closing plate 75 can move quickly and tightly close the stopper 72, thereby preventing the adsorbent from leaking from the feed pipe 4. This design ensures the sealing of the system and reduces the risk of adsorbent waste and environmental pollution.

[0046] The working principle of the present invention is as follows: in the initial state, the push rod 63 in the lifting device 6 pushes the adsorbent box 5 upward under the action of the spring 1 67, so that the adsorbent box 5 is moved to the top limit position of the adjustment groove 11. At the same time, as the spring 1 67 pushes the push rod 63 upward, the elastic rope 64 at the bottom end of the push rod 63 pulls the linkage block 65 upward, so that the linkage block 65 drives the baffle plate 14 to move upward to block the discharge port 12. When the adsorbent box 5 moves upward, it drives the push column 84 upward, so that the conical surface at the top of the push column 84 abuts against the ball at the bottom end of the push plate 74, and pushes the two groups of push plates 74 to move outward, so that the spring 2 73 is stretched. When the two groups of push plates 74 are pushed open, the closing plate 75 therein is connected due to the adsorption of the magnetic block, so that the push column 84 is inserted into the C-shaped notch. As the top column 84 continues to move upward, the arc surface at the top of the support plate 83 abuts against the ball at the bottom of the push plate 74, pushing the push plate 74 to continue to move outward. As the movement continues, the arc surface at the top of the support plate 83 abuts against the lower contour of the C-shaped notch of the closing plate 75, causing the two sets of closing plates 75 to retract into the stopper 72 until the width of the stopper 72 is the same as the diameter of the feed cylinder in the adsorbent box 5, so that the feed cylinder in the adsorbent box 5 is inserted into the feed pipe 4. When the top column 84 continues to move upward, it is inserted into the slot 852. Under the action of the guide groove 841 and the guide block 853, the rotating column 85 rotates and drives the stirring blade 851 to rotate. As the stirring blade 851 rotates, the adsorbent in the feed pipe 4 is driven to slide downward and enter the adsorbent box 5 The adsorbent is guided by the feed hopper 82 so that it falls on the cloth block 81 and slides into the adsorbent box 5. As the adsorbent in the adsorbent box 5 increases, the weight of the adsorbent box 5 continues to increase, causing the adsorbent box 5 to push the top rod 63 to move downward until the adsorbent box 5 moves to the middle position of the adjustment slot 11. During the movement, the top column 84 and the feed cylinder in the adsorbent box 5 gradually withdraw from the feed pipe 4. When the feed cylinder in the adsorbent box 5 withdraws first, the stopper 72 gradually closes under the action of the spring 73 until the stopper 72 abuts against the side end of the top column 84. At this time, under the action of the magnetic block, the two sets of closing plates 75 move toward each other until they abut, causing the feed cylinder in the adsorbent box 5 to move out of the feed pipe 4, and the top column 84 Continue to stay in the feed pipe 4, and finally, with the withdrawal of the top column 84 and the action of its top cone, the stopper 72 gradually closes and enters a closed state. Then, when the fan 9 is started, the outside air passes through the through hole at the bottom of the outer barrel 1, enters the outer barrel 1, and moves upward. During the movement, the air passes through the through hole opened on the adsorbent box 5, contacts with the adsorbent in the adsorbent box 5, removes impurities, harmful gases and part of the moisture in the air, and is finally discharged through the through hole below the fan 9. When the adsorbent in the adsorbent box 5 is in an adsorption saturation state, the weight of the adsorbent reaches the maximum value. At this time, the adsorbent box 5 presses down the top rod 63 to shrink the spring 67 until the bottom end of the adsorbent box 5 is magnetically adsorbed and connected to the bottom end of the inside of the adjustment slot 11. At this time,The weight of the adsorbent box 5 plus the magnetic attraction force of the magnet at the bottom end of the adsorbent box 5 and the bottom end of the adjusting slot 11 is greater than the elastic force of the spring 67, so that the adsorbent box 5 is restricted in the current state. At the same time, due to the downward movement of the top rod 63, it will contact the linkage block 65 at the top end of the limiting slot 62, and push the linkage block 65 to move downward, so that the baffle 14 moves downward in the installation slot 13, and the discharge port 12 leaks out. At this time, the adsorbent in the adsorbent box 5 is discharged through the discharge port 12. When the adsorbent in the adsorbent box 5 is completely discharged, the weight of the adsorbent box 5 plus the magnetic attraction force of the magnet at the bottom end of the adsorbent box 5 and the bottom end of the adjusting slot 11 is less than the elastic force of the spring 67, so that the spring 67 returns to its original length and pushes the adsorbent box 5 to move upward, so that the adsorbent The box 5 is moved to the top limit position of the adjustment groove 11, and at the same time, as the spring 167 pushes the top rod 63 to move up, the elastic rope 64 at the bottom end of the top rod 63 pulls the linkage block 65 to move up, so that the linkage block 65 drives the baffle 14 to move up and block the discharge port 12 again; through the coordinated action of the top rod 63 and the spring 167 in the lifting device 6, the height of the adsorbent box 5 can be automatically adjusted according to the weight of the adsorbent in the adsorbent box 5. When the adsorbent is saturated, the weight of the adsorbent box 5 increases, pressing the top rod 63 downward to shrink the spring 167. When the adsorbent is discharged, the spring 167 returns to its original length and pushes the adsorbent box 5 up, ensuring that the adsorbent box 5 is always at the optimal working height, and through the linkage of the top rod 63 and the elastic rope 64, the baffle is realized. 14 is an automatic switch. When the adsorbent box 5 presses down the push rod 63, the baffle 14 opens to allow the adsorbent to be discharged and automatically discharge. When the adsorbent box 5 moves up, the baffle 14 closes to prevent the adsorbent from leaking. This automatic control system simplifies the operation process and improves the automation level of the system. The anti-discharge device 7 ensures that when the adsorbent box 5 leaves the feed pipe 4, the closing plate 75 can move quickly and tightly close the stopper 72 to prevent the adsorbent from leaking from the feed pipe 4. This design enhances the sealing of the system and reduces the risk of adsorbent waste and environmental pollution. The push plate 74 can automatically move outward under the action of the top column 84, so that the closing plate 75 retracts into the stopper 72 to keep the feed pipe 4 unobstructed. This automatic control system The system reduces manual intervention and improves the convenience and efficiency of operation. Through the cooperation of the cloth block 81 and the feed hopper 82 in the discharge device 8, it is ensured that the adsorbent can be evenly distributed inside the adsorbent box 5 when discharged from the feed pipe 4. This uniform distribution helps to improve the use efficiency of the adsorbent and the gas purification effect, ensuring that the airflow can fully contact the adsorbent when passing through it, so as to better remove impurities and harmful gases in the air. The rotating column 85 rotates under the action of the top column 84, driving the stirring blade 851 to rotate, driving the adsorbent in the feed pipe 4 to slide downward and enter the feed hopper 82 in the adsorbent box 5. This automatic stirring system ensures the fluidity and uniform distribution of the adsorbent, and avoids the adsorbent from being blocked or unevenly distributed in the feed pipe 4.

First, the adsorbent box (5) not filled with adsorbent is lifted up by the lifting device (6) to move the adsorbent box (5) to the upper limit position of the regulating tank (11). During the movement, the top column (84) and the support plate (82) at the top of the feed pipe of the adsorbent box (5) activate and open the anti-discharge device (7), so that the feed pipe of the adsorbent box (5) is completely inserted into the feed pipe (4), and enters the feeding state; S2.
