[0002] In addition to formaldehyde, the building and decoration materials used in home house decoration also produce radon gas. The main sources of radon pollution are underground rocks and soil as well as building and decoration materials. The filter materials in existing home air purification equipment generally use activated carbon particles (activated carbon has a good adsorption effect on radon gas), and the activated carbon particles are generally packaged in a small bag structure, and a filtration system is formed by stacking multiple bags. When the use time is too long, the entire package needs to be replaced. First of all, this situation will cause a waste of activated carbon. This is because the adsorption effect of bagged activated carbon is gradually from the surface to the inside, which can easily lead to insufficient reaction of the middle part of the bagged activated carbon; secondly, the existing home air purification equipment cannot automatically replace the saturated activated carbon, and needs to be manually installed and placed, which is time-consuming and laborious.

DETAILED DESCRIPTION

[0035] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] Embodiment 1

[0037] See also Figure 1-Figure 16 The present invention provides a mobile radon removal air purification device, comprising a body 1 with universal wheels at the bottom, a fan device 2 and an intelligent control system 3 are arranged in the body 1, a filter element 41 is arranged above the fan device 2, and a modified activated carbon cotton filter 4 is arranged on the inner wall of the body 1; it also comprises a sleeve tube 5 connected and fixed with the filter element 41, a self-rotating plate 6 is rotatably connected in the sleeve tube 5, a rotating plate 7 is rotatably matched in the sleeve tube 5, a conveying channel is arranged on the side of the rotating plate 7, a matching rod 8 is fixedly connected to the rotating plate 7, a first sleeve 9 is arranged on the central axis of the sleeve tube 5, a rotating rod 10 connected and fixed to the rotating plate 7 is penetrated in the first sleeve 9, and the rotating rod A plurality of wedge blocks 11 are fixedly connected to 10, telescopic sleeves 12 are fixedly connected to both ends of the rotating plate 7, and a telescopic input pipe 13 connected to the rotating plate 7 is fixedly connected to the middle of the rotating plate 7; a rotating assembly, the rotating assembly is used to make the rotating rod 10 move downward at intervals and always keep rotating, and through the telescopic sleeve 12, the telescopic input pipe 13 and the conveying channel, the saturated activated carbon is conveyed layer by layer and new activated carbon is released; a switching assembly, the switching assembly acts on the wedge blocks 11 through the matching rod 8 that performs a circular motion, so that the rotating rod 10 moves downward at intervals, and when the rotating rod 10 moves to the bottom, the rotating rod 10 instantly resets upward;

[0038] The overall idea of ​​the present application is as follows: the motor 20 is started, driving the rotating rod 10 to rotate counterclockwise, thereby causing the rotating plate 7 to rotate, thereby pressing and pushing the activated carbon particles between the filter screen plate 26 and the rotating plate 6, and the saturated activated carbon particles are transported into the telescopic sleeve 12 through the sliding groove 14, and enter the release pipe 25 through the movable channel between the rotating ring plate 23 and the movable ring plate 24, thereby releasing the saturated activated carbon particles;

[0039] At the same time, the telescopic input tube 13 allows new activated carbon particles to enter between the filter screen plate 26 and the rotating plate 6 through the connecting hole 15 and the through hole 16, thereby replenishing and replacing new activated carbon particles. In this solution, the saturated activated carbon particles are first released, and then new activated carbon particles are input through the telescopic input tube 13;

[0040] After the rotating plate 7 rotates one circle, the rotating plate 7 moves downward a certain distance (the height distance of the wedge block 11), and then the rotating plate 7 continues to rotate one circle, and then the rotating plate 7 continues to move downward, and repeats this process in sequence, so that the rotating plate 7 replaces the activated carbon particles between the filter mesh plate 26 and the self-rotating plate 6 at intervals, that is, the activated carbon particles between the filter mesh plate 26 and the self-rotating plate 6 are replaced layer by layer. By replacing the activated carbon particles layer by layer, the activated carbon particles are replaced from top to bottom, thereby ensuring the full utilization of the activated carbon to the greatest extent. In addition, in this scheme, there is no need for multiple bagged activated carbon bags to be piled up between the filter mesh plate 26 and the self-rotating plate 6 as in the prior art. Only scattered activated carbon particles are required to be filled between the filter mesh plate 26 and the self-rotating plate 6. Compared with multiple bagged activated carbon bags, the method in this scheme is more helpful to fully utilize the adsorption capacity of the activated carbon.

[0041] The conveying channel includes two sliding grooves 14 and a connecting hole 15 located above the sliding grooves 14. The two sliding grooves 14 are respectively located at the left side of the front end of the bottom of the rotating plate 7 and the right side of the rear end of the bottom. The inner ends of the two sliding grooves 14 are connected to each other. The other end of the sliding groove 14 is connected and fixed to the telescopic sleeve 12. The two connecting holes 15 are respectively located at the left side of the rear end of the top of the rotating plate 7 and the right end of the front side of the top. The inner ends of the two connecting holes 15 are connected and fixed to the telescopic input pipe 13 that penetrates into the rotating plate 7. A plurality of through holes 16 connected to the connecting holes 15 are opened on the rotating plate 7.

[0042] In the present application, the rotating plate 7 rotates counterclockwise, and the saturated activated carbon particles enter the telescopic sleeve 12 through the sliding groove 14, and enter the release tube 25 through the movable channel between the rotating ring plate 23 and the movable ring plate 24, thereby releasing the saturated activated carbon particles. In this solution, the movable rotating plate and the telescopic sleeve 12 rotate, and the rotating ring plate 23 and the sleeve tube 5 are fixed in position;

[0043] When the saturated activated carbon particles are cleaned, the telescopic input pipe 13 allows the activated carbon particles to enter the rotating plate 7, and enter between the filter screen plate 26 and the rotating plate 6 through the connecting hole 15 and the through hole 16, thereby completing the replacement and replenishment of the activated carbon particles.

[0044] The rotating assembly includes a second sleeve 17 movably matched with the rotating rod 10 , the second sleeve 17 is fixedly connected with a first fixed plate 18 and a second fixed plate 19 , the first sleeve 9 is connected and fixed with the rotating plate 7 , and the first sleeve 9 is movably matched with the rotating plate 6 .

[0045] The rotating assembly also includes a motor 20 connected and fixed to the filter element 41, an L-shaped rod 21 is fixedly connected between the motor 20 and the second sleeve 17, a rectangular rod 22 that penetrates the rotating rod 10 is fixedly connected to the output shaft of the motor 20, a rotating ring plate 23 is fixedly connected to the bottom of the sleeve tube 5, a movable ring plate 24 that is connected to the telescopic sleeve 12 is rotatably connected to the rotating ring plate 23, an inclined release pipe 25 is connected and fixed to the rotating ring plate 23, a filter screen plate 26 is fixedly connected to the top of the sleeve tube 5, a third sleeve 27 that is movably matched with the filter screen plate 26 is fixedly connected to the rotating plate 7, a tension spring 28 is fixedly connected between the telescopic input pipe 13 and the third sleeve 27, and in the present application, the second sleeve 17 is fixed in position and does not rotate or move.

[0046] The switching assembly includes a pressure rod 29 movable in the first fixed plate 18 and the second sleeve 17. The pressure rod 29 is pressed and matched with the truncated cone-shaped wedge block 11. The first fixed plate 18 is rotatably connected with a first arc rod 30 through a first torsion spring rod. The end of the first arc rod 30 is fixedly connected with a pressure block 31 that is pressed and matched with the matching rod 8. The first arc rod 30 and the pressure rod 29 are rotatably connected through a torsion spring.

[0047] The switching assembly also includes a pressure plate 32 rotatably connected to the second fixed plate 19 through a second torsion spring rod, a second arc rod 33 is rotatably connected inside the second fixed plate 19, a sliding groove 34 is provided on the pressure plate 32, the end of the second arc rod 33 is slidably matched with the sliding groove 34, a limiting rod 35 slidably matched with the pressure plate 32 is fixedly connected to the end of the second arc rod 33, and a wedge plate 36 is fixedly connected to the matching rod 8 and is pressed against the second arc rod 33.

[0048] In the present application, when the rotating plate 7 rotates, it drives the matching rod 8 to make a circular motion, and the matching rod 8 contacts the pressing block 31 (the pressing block 31 is conical), so that the first arc rod 30 rotates, and the pressing rod 29 presses the wedge block 11, so that the rotating rod 10 overcomes the action of the tension spring 28, moves downward, and maintains the state of the rotating rod 10 after the adjustment position under the action of the pressing plate 32;

[0049] At the same time, the signal control causes the motor 20 to rotate the rectangular rod 22, thereby causing the rotating rod 10 and the rotating plate 7 to rotate (the rotating rod 10 and the rectangular rod 22 are movably matched);

[0050] When the rotating plate 7 moves down to the bottom position, the wedge plate 36 (the two sides of the wedge plate 36 are inclined at an angle) contacts the second arc rod 33, causing the second arc rod 33 to rotate, thereby causing the pressing plate 32 to rotate downward, thereby loosening the restriction of the pressing plate 32 on the wedge block 11, and under the action of the tension spring 28, the rotating plate 7 is quickly reset upward, and then the rotating plate 7 continues to move downward at intervals, and reciprocates in sequence;

[0051] In this solution, when the wedge block 11 is at the highest point, the wedge block 11 is located lower than the first fixing plate 18;

[0052] The first sleeve 9, the second sleeve 17 and the third sleeve 27 are used to prevent activated carbon particles from entering and affecting the use of the equipment;

[0053] It is worth noting that, while the rotating plate 7 moves downward in intervals, the telescopic sleeve 12 is extended and retracted, and the telescopic movement facilitates the saturated activated carbon particles to enter the release tube 25;

[0054] The telescopic input pipe 13 is self-rotatingly matched with an external input device (conventional technology) and connected, and new activated carbon particles are input into the telescopic input pipe 13 through the input device and enter the rotating plate 7, and the new activated carbon particles are transported into between the filter screen plate 26 and the rotating plate 7 through the through hole 16;

[0055] The release tube 25 is used to transport the activated carbon particles that have been absorbed saturated out of the body 1. In the present application, the outer end of the release tube can be connected to an external negative suction device (conventional technology). On the one hand, it helps to transport the saturated activated carbon particles out of the body 1. On the other hand, by maintaining the negative pressure device, the activated carbon particles are not transported out of the body 1, and the rotating plate 7 is rotated to stir the activated carbon particles located between the filter plate 26 and the rotating plate 6 to ensure that the activated carbon particles are fully utilized, thereby avoiding the situation where only the activated carbon particles on the surface are saturated, while the activated carbon particles at the bottom do not fully utilize the adsorption effect.

[0056] A pressing column 37 is fixedly connected to the pressing rod 29 , and an inclined plate 38 that presses against the pressing column 37 is fixedly connected inside the first fixing plate 18 .

[0057] In the present application, after the pressure rod 29 presses the wedge block 11 downward, the pressure column 37 moves downward synchronously and slides with the inclined plate 38, so that the end of the pressure rod 29 is away from the wedge block 11, making it easier for the pressure rod 29 to reciprocate to act on the wedge block 11 and cooperate with the pressure plate 32 to stabilize the wedge block 11.

[0058] The filter element 41 is a modified coconut shell activated carbon block filter, a modified activated carbon honeycomb activated carbon filter and a high efficiency filter which are arranged in sequence.

[0059] In the present application, the radon and its factors in the air are initially adsorbed by the high-efficiency coconut shell modified activated carbon cotton filter 4, and then the airflow is driven by the fan device 2 to send the airflow to the modified coconut shell activated carbon block filter for the second adsorption filtration, and then the airflow is purified and adsorbed by the third modified activated carbon honeycomb activated carbon filter, and then reaches the fourth H13 high-efficiency filter for purification and filtration before being discharged, and the radon and its factors are continuously circulated and adsorbed and purified. The structural mode of the existing products is mostly a steel structure + high-voltage electrostatic field purification filter element or a micro-electrostatic dust collection filter element, etc. The effect of this method in removing radon and its factors is not very ideal;

[0060] Modified activated carbon cotton filter 4: The function is to initially adsorb and purify radon gas in indoor air;

[0061] Modified coconut shell activated carbon block filter: It is used for secondary adsorption of radon gas and its factors in indoor air to achieve secondary treatment adsorption;

[0062] Modified activated carbon honeycomb activated carbon filter: It is used to adsorb and purify indoor radon and its factors for the third time. After three purifications of the adsorbed air, radon and its factors can reach a higher purification emission standard.

[0063] High efficiency filter: Its function is to improve the air to high quality emission standards through high efficiency filter modules;

[0064] Intelligent control system 3: Through the detection data of radon gas and its factors, the intelligent control operation of the purification and radon removal device can be achieved.

[0065] Embodiment 2

[0066] See also Figure 8-Figure 9 and Figure 13-Figure 16 The motor 20 is fixedly connected with a pneumatic cylinder 39 , and the end of the pneumatic rod of the pneumatic cylinder 39 is fixedly connected with a moving rod 40 , and the moving rod 40 is pressed and matched with the first arc rod 30 .

[0067] The pneumatic cylinder 39 is controlled by a signal to move the moving rod 40 up and down. Under the action of the first torsion spring rod, the angle of the first arc rod 30 is adjusted to control the interval time of the descent of the rotating rod 10. For example, after the rotating rod 10 rotates multiple times, the angle of the first arc rod 30 is changed by the moving rod 40, so that the position of the pressure block 31 can contact the matching rod 8, thereby completing the descent of the rotating rod 10. When the rotating rod 10 needs to continue to rotate in the original position, the position of the pressure block 31 is prevented from contacting the matching rod 8 by the moving rod 40. In this embodiment, a detection sensor that cooperates with the signal of the pneumatic cylinder 39 is set on the rotating plate 7. The detection sensor detects the saturation degree of the activated carbon. When the detection sensor detects that the saturation degree of the activated carbon reaches a certain value, the moving rod 40 adjusts the position of the pressure block 31 to enable the rotating plate 7 to fully rotate in the original position.
