Description

Technical Field

[0002] Formaldehyde is a colorless gas with a strong pungent odor. It is easily soluble in water, alcohol and ether. Formaldehyde is in gaseous state at room temperature. The main hazard of formaldehyde is irritation to the skin and mucous membranes. When formaldehyde reaches a certain concentration indoors, people will feel uncomfortable, which may cause red eyes, itchy eyes, throat discomfort or pain, hoarseness, sneezing, chest tightness, asthma, dermatitis, etc. After interior decoration, the formaldehyde content in the room will exceed the standard. If formaldehyde is not removed, it will threaten people's health. Now people mainly remove formaldehyde by activated carbon adsorption and ventilation.

[0003] At present, activated carbon is prone to saturation during use. When the temperature rises, the saturated activated carbon will re-emit some of the adsorbed formaldehyde gas into the room, failing to achieve the desired adsorption effect and reducing the quality of formaldehyde removal.

[0022] The beneficial effects of the present invention are as follows:

[0023] 1. In the present invention, the storage part is moved to the highest point, the conveying mechanism brings the activated carbon particles at the bottom of the No. 1 cylinder into the No. 1 cylindrical structure, the axial flow fan sucks the air outside the box into the containing cavity, the activated carbon particles absorb the formaldehyde in the air, so that the box moves according to the set route to absorb the formaldehyde in the indoor air; after the activated carbon particles in the containing cavity have been used for a period of time, the activated carbon particles slide between the No. 2 cylindrical structure and the No. 3 cylindrical structure and enter the storage part, the conveying mechanism conveys the activated carbon particles at the bottom of the No. 1 cylinder into the containing cavity, and continuously absorbs the formaldehyde in the indoor air; the absorption and purification mechanism absorbs and purifies the formaldehyde adsorbed on the activated carbon particles in the storage part, so that the activated carbon particles restore the adsorption capacity and realize the recycling of the activated carbon particles; the activated carbon particles do not need to be moved all the time, so the activated carbon particles can be recycled, the probability of damage to the activated carbon particles is reduced, the adsorption capacity of the activated carbon is guaranteed, and the formaldehyde removal quality is improved.

[0024] 2. In the present invention, the heating element heats the activated carbon particles close to the No. 2 cylindrical structure, and the No. 2 stirring structure stirs the activated carbon particles to increase the temperature of the activated carbon particles, so that the formaldehyde adsorbed in the activated carbon particles volatilizes, and the formaldehyde passes through the No. 3 cylindrical structure, the No. 1 connecting pipe, the exhaust fan, and the No. 2 connecting pipe into the purification box, and the liquid chemical agent absorbs and purifies the formaldehyde, thereby completing the absorption and purification of the formaldehyde adsorbed on the activated carbon particles; after the formaldehyde adsorbed on the activated carbon particles is absorbed and purified, the No. 3 cylindrical body rotates forward, and the No. 3 drop hole moves When the annular rotating plate continues to rotate, the stirring structure No. 2 pushes the activated carbon particles remaining in the storage component to move, so that the remaining activated carbon particles pass through the No. 1 and No. 3 drop holes and fall into the storage component; after all the activated carbon particles fall, the No. 3 cylinder body rotates in the opposite direction, and the No. 3 bottom plate structure blocks the No. 1 drop hole to prevent the activated carbon particles that enter the storage component later from falling directly into the No. 1 cylinder body, thereby improving the reliability of the absorption and purification mechanism.

[0025] 3. In the present invention, the No. 2 power mechanism drives the conveying member to rotate, and drives the spiral conveying structure to rotate. The spiral conveying structure allows the activated carbon particles at the bottom of the No. 1 cylinder to pass through the No. 4 cylinder and enter the No. 1 cylindrical structure, so that the activated carbon particles enter the containing cavity through the No. 1 opening.

[0026] 4. In the present invention, the semiconductor refrigeration component cools down the activated carbon particles near the No. 2 cylindrical structure. The No. 2 power mechanism drives the stirring member to rotate through the controller, and drives the No. 1 stirring structure to rotate. The No. 1 stirring structure stirs the activated carbon particles, thereby reducing the temperature of the entire activated carbon particles, increasing the adsorption capacity of the activated carbon particles, and improving the formaldehyde removal quality.

[0027] 5. In the present invention, the No. 2 rotating shaft drives the No. 4 rotating member to rotate forward, the No. 4 ball drives the No. 4 limiting structure to rotate together, drives the No. 4 connecting part to rotate forward, drives the No. 4 cylindrical structure to rotate, drives the spiral conveying structure to rotate, and transports the activated carbon particles; when the No. 2 rotating shaft rotates forward, the No. 2 ball moves along the surface of the No. 1 slope structure, so that the No. 2 connecting part forms a rotational connection with the No. 1 connecting part, preventing the No. 1 cylindrical structure from rotating synchronously with the No. 2 rotating shaft, preventing the No. 1 cylindrical structure from rotating synchronously with the spiral conveying structure, and preventing the No. 1 cylindrical structure from rotating synchronously with the spiral conveying structure. The rotation prevents the activated carbon particles from moving upward through the No. 1 cylindrical structure, thereby improving the reliability of the conveying mechanism; the shaft of the No. 2 motor drives the No. 2 rotating shaft to rotate in the opposite direction, and the No. 2 ball drives the No. 1 limiting structure to rotate, which drives the No. 1 connecting part to rotate, which drives the No. 1 cylindrical structure to rotate, and drives the agitator to rotate; when the No. 2 rotating shaft rotates in the opposite direction, the No. 4 ball moves along the surface of the No. 4 slope structure, so that the conveying member remains stationary, preventing the spiral conveying structure from stirring the activated carbon particles in the No. 1 cylinder when the agitator rotates, thereby reducing the chance of damage to the activated carbon particles in the No. 1 cylinder.

[0053] The storage member 5 comprises a No. 1 bottom plate structure 51, a No. 2 cylindrical structure 52 and a No. 3 cylindrical structure 53; a No. 3 cylindrical structure 53 is arranged outside the No. 2 cylindrical structure 52; the lower end of the No. 2 cylindrical structure 52 and the lower end of the No. 3 cylindrical structure 53 are connected through the No. 1 bottom plate structure 51; No. 1 drop holes 511 are evenly spaced on the No. 1 bottom plate structure 51; the No. 1 bottom plate structure 51 is slidably connected to the No. 1 cylinder body 11; the side wall of the No. 2 cylindrical structure 52 is clearance-matched with the side wall of the No. 2 cylinder body 12; the No. 3 cylinder body 13 is rotatably connected to the outer side of the No. 3 cylindrical structure 53; a No. 3 bottom plate structure 131 is arranged at the lower end of the No. 3 cylinder body 13; No. 3 drop holes 1311 are evenly spaced on the No. 3 bottom plate structure 131;

[0054] An absorption and purification mechanism 6 is arranged in the box body 1; the absorption and purification mechanism 6 is used for absorbing and purifying the formaldehyde on the activated carbon particles in the storage member 5; a walking mechanism 7 is connected to the lower end of the box body 1; the walking mechanism 7 is used for driving the box body 1 to move; the conveying mechanism 4 is connected to the No. 2 cylinder body 12; the No. 1 box body 1 is connected to a No. 1 power mechanism 8 and a No. 2 power mechanism 9; the No. 1 power mechanism 8 is used for driving the storage member 5 to rise or fall; the No. 2 power mechanism 9 is used for driving the agitator 3 to rotate; the No. 2 power mechanism 9 is used for driving the conveying mechanism 4 to convey the activated carbon particles.

[0055] During use, the user operates the No. 1 power mechanism 8 through the controller, and the No. 1 power mechanism 8 drives the storage member 5 to move upward, so that the storage member 5 moves to the highest point. At this time, the No. 2 cylindrical structure 52 and the upper end surface of the No. 2 cylinder body 12 form a holding cavity. Then the controller operates the No. 2 power mechanism 9, and the No. 2 power mechanism 9 drives the conveying mechanism 4 to operate. The conveying mechanism 4 brings the activated carbon particles at the bottom of the No. 1 cylinder body 11 into the No. 1 cylindrical structure 31, so that the activated carbon particles enter the holding cavity through the No. 1 opening 311. After the amount of activated carbon particles in the holding cavity meets the requirements, ... The power mechanism 9 stops working, so that the conveying mechanism 4 stops working, and then the controller rotates the axial flow fan 2, and the axial flow fan 2 sucks the air outside the box body 1 into the containing cavity, so that the air passes through the gaps between the activated carbon particles and the No. 2 through hole 122 to move into the No. 2 cylinder body 12, and passes through the No. 2 tubular structure 121 and the No. 1 tubular structure 111 to move to the outside of the box body 1. When the air passes through the activated carbon particles, the activated carbon particles absorb the formaldehyde in the air. At the same time, the controller operates the walking mechanism 7, so that the box body 1 moves according to the set route to absorb the formaldehyde in the indoor air.

[0056] After the activated carbon particles in the holding cavity have been used for a period of time, the activated carbon particles reach a saturated state, and the controller activates the No. 1 power mechanism 8, which drives the storage member 5 to move downward, so that the storage member 5 moves to the lowest position. At this time, the highest point of the upper end of the No. 2 cylindrical structure 52 is flush with the upper end surface of the No. 2 cylinder body 12, and the activated carbon particles slide between the No. 2 cylindrical structure 52 and the No. 3 cylindrical structure 53 and enter the storage member 5 (the No. 3 drop hole 1311 and the No. 1 drop hole 511 are staggered to prevent the activated carbon particles from directly passing through the No. 1 drop hole 511 and the No. 3 drop hole 1311 and falling into the No. 1 cylinder body 11), and then the controller activates the No. 2 power mechanism 8. The mechanism 9 works, the No. 2 power mechanism 9 drives the stirring member 3 to rotate, drives the No. 1 stirring structure 32 to rotate, the No. 1 stirring structure 32 stirs the activated carbon particles remaining on the upper end surface of the No. 2 cylinder 12, so that the activated carbon particles remaining on the upper end surface of the No. 2 cylinder 12 move into the storage member 5, and then the controller stops the No. 2 power mechanism 9 and makes the No. 1 power mechanism 8 work to move the storage member 5 to the highest position, and then makes the No. 2 power mechanism 9 work again, and the No. 2 power mechanism 9 drives the conveying mechanism 4 to work, and the conveying mechanism 4 conveys the activated carbon particles at the bottom of the No. 1 cylinder 11 to the containing cavity, so as to continuously remove the formaldehyde in the indoor air. Continue to absorb; after the storage part 5 moves to the highest position, the controller makes the absorption and purification mechanism 6 work, and the absorption and purification mechanism 6 absorbs and purifies the formaldehyde adsorbed on the activated carbon particles in the storage part 5, so that the activated carbon particles restore their adsorption capacity, and then the absorption and purification mechanism 6 drives the third cylinder 13 to rotate forward, drives the third bottom plate structure 131 to rotate forward, and moves the third drop hole 1311 to the bottom of the first drop hole 511, so that the activated carbon particles in the storage part 5 pass through the first drop hole 511 and the third drop hole 1311 and fall to the lower part of the first cylinder 11, so as to realize the recycling of the activated carbon particles and save the total amount of activated carbon particles; After all the activated carbon particles fall into the No. 1 cylinder 11, the absorption and purification mechanism 6 drives the No. 3 cylinder 13 to rotate in the opposite direction, and drives the No. 3 bottom plate structure 131 to rotate in the opposite direction, so that the No. 3 drop hole 1311 is staggered with the No. 1 drop hole 511, and the No. 3 bottom plate structure 131 blocks the No. 1 drop hole 511 to prevent the activated carbon particles that enter the storage unit 5 later from directly falling into the No. 1 cylinder 11 through the No. 1 drop hole 511, thereby improving the reliability of the absorption and purification mechanism 6; the absorption and purification mechanism 6 absorbs and purifies the formaldehyde adsorbed in the activated carbon particles, thereby preventing the formaldehyde adsorbed in the activated carbon particles from re-entering the air, thereby improving the formaldehyde removal quality;In order to realize the recycling of activated carbon particles, some formaldehyde removal devices keep the activated carbon particles moving, which will increase the friction between the activated carbon particles and between the activated carbon particles and the channels, increase the probability of activated carbon particles being damaged, and reduce the adsorption capacity of activated carbon particles. However, the activated carbon particles in this formaldehyde removal device do not need to be moved all the time, so the activated carbon particles can be recycled, the probability of activated carbon particles being damaged is reduced, the adsorption capacity of activated carbon is guaranteed, and the formaldehyde removal quality is improved. ;

[0057] The absorption and purification mechanism 6 comprises an annular rotating plate 61, a heating element 62, a No. 1 driving element 63, a No. 1 sliding element 64, a No. 1 elastic element 65, a No. 1 fixing element 66, a purification box 67, a No. 3 power assembly 68, an air extractor 69, a No. 1 connecting pipe 691 and a No. 2 connecting pipe 692; the annular rotating plate 61 is rotatably connected in the box body 1; a No. 2 connecting structure 611 is evenly spaced on the lower end surface of the annular rotating plate 61; a No. 2 stirring structure 612 is provided at the lower end of the No. 2 connecting structure 611; the heating element 62 is fixedly connected to the side wall of the No. 2 cylindrical structure 52; an annular connecting structure 613 is provided on the annular rotating plate 61; and a No. 1 groove 6131 is evenly spaced on the lower surface of the annular connecting structure 613;

[0059] A No. 3 avoidance groove 133 is provided on the side wall of the No. 3 cylinder body 13; a No. 3 tubular structure 531 is provided on the outer wall of the No. 3 cylindrical structure 53; the No. 3 tubular structure 531 passes through the No. 3 avoidance groove 133; the box body 1 is fixedly connected to the purification box 67; the purification box 67 contains liquid chemical agents; the box body 1 is fixedly connected to the No. 1 connecting pipe 691; the purification box 67 is fixedly connected to the vacuum pump 69; the air inlet end of the vacuum pump 69 is fixed and connected to the No. 1 connecting pipe 691; the air outlet end of the vacuum pump 69 is connected to the No. 2 connecting pipe 692; one end of the No. 2 connecting pipe 692 is fixed and connected to the air outlet end of the vacuum pump 69; the other end of the No. 2 connecting pipe 692 is arranged close to the bottom plate of the purification box 67;

[0060] The box body 1 is connected to a third power assembly 68 ; the third power assembly 68 is used to drive the annular rotating plate 61 to rotate.

[0061] After the storage unit 5 moves to the highest position (at this time, the No. 3 tubular structure 531 is facing the No. 1 connecting pipe 691, and the No. 3 tubular structure 531 is connected to the No. 1 connecting pipe 691), when it is necessary to absorb and purify the formaldehyde adsorbed on the activated carbon particles in the storage unit 5, the controller makes the heating unit 62 and the No. 3 power assembly 68 work, the heating unit 62 heats the activated carbon particles close to the No. 2 tubular structure 52, and the No. 3 power assembly 68 drives the annular rotating plate 61 to rotate in the opposite direction (at this time, the No. 3 drop hole 1311 is staggered with the No. 1 drop hole 511, and the No. 3 bottom plate structure 131 is aligned with the No. 1 drop hole 511). The second stirring structure 612 is driven to rotate, and the second stirring structure 612 is driven to rotate. The second stirring structure 612 stirs the activated carbon particles to increase the temperature of the activated carbon particles, so that the formaldehyde adsorbed in the activated carbon particles is volatilized. At the same time, the controller operates the vacuum pump 69 to make the formaldehyde enter the purification box 67 through the third tubular structure 531, the first connecting pipe 691, the vacuum pump 69, and the second connecting pipe 692. The liquid chemical agent (the liquid chemical agent is a formaldehyde scavenger or a formaldehyde dissolving enzyme) absorbs and purifies the formaldehyde, thereby completing the absorption and purification of the formaldehyde adsorbed on the activated carbon particles;

[0062] After the formaldehyde adsorbed on the activated carbon particles is absorbed and purified, the controller causes the No. 3 power component 68 to drive the annular rotating plate 61 to rotate forward. When the No. 1 groove 6131 moves to the top of the No. 1 driving member 63, the elastic force of the No. 1 elastic member 65 causes the No. 1 sliding member 64 and the No. 1 driving member 63 to move upward, so that the No. 1 driving member 63 is in contact with the No. 1 groove 6131. ​​When the annular rotating plate 61 rotates, it drives the No. 1 driving member 63 to rotate, and drives the No. 3 cylinder 13 to rotate forward. When the side wall of one side of the No. 3 avoidance groove 133 is in contact with the No. 3 tubular structure 531, the No. 3 cylinder 13 stops rotating. At this time, the No. 3 drop hole 1311 moves to the bottom of the No. 1 drop hole 511. , the activated carbon particles fall into the storage member 5 through the No. 1 drop hole 511 and the No. 3 drop hole 1311. When the annular rotating plate 61 continues to rotate, the force of the side wall of the No. 1 groove 6131 on the No. 1 driving member 63 overcomes the elastic force of the No. 1 elastic member 65, so that the No. 1 driving member 63 and the No. 1 sliding member 64 move downward, so that the No. 1 driving member 63 is separated from the No. 1 groove 6131, and the annular rotating plate 61 continues to rotate, driving the No. 2 connecting structure 611 and the No. 2 stirring structure 612 to rotate, and the No. 2 stirring structure 612 pushes the activated carbon particles remaining in the storage member 5 to move, so that the remaining activated carbon particles pass through the No. 1 drop hole 511 and the No. 3 drop hole 1311 and fall into the storage member 5;

[0063] After all the activated carbon particles have fallen off, the controller enables the No. 3 power assembly 68 to drive the annular rotating plate 61 to rotate in the opposite direction. When the No. 1 groove 6131 moves to the top of the No. 1 driving member 63, the elastic force of the No. 1 elastic member 65 causes the No. 1 sliding member 64 and the No. 1 driving member 63 to move upward, so that the No. 1 driving member 63 is pressed against the No. 1 groove 6131. ​​When the annular rotating plate 61 rotates in the opposite direction, it drives the No. 1 driving member 63 to rotate, and drives the No. 3 cylinder 13 to rotate in the opposite direction. When the side wall on the other side of the No. 3 avoidance groove 133 presses against the No. 3 tubular structure 531, the No. 3 cylinder 13 stops rotating. At this time, the No. 3 falling hole 1311 is staggered with the No. 1 falling hole 511, and the No. 3 bottom plate structure 131 blocks the No. 1 falling hole 511 to prevent the activated carbon particles that enter the storage member 5 at a later time from falling directly into the No. 1 cylinder 11, thereby improving the reliability of the absorption and purification mechanism 6.

[0065] When the conveying mechanism 4 is needed to convey the activated carbon particles into the containing chamber, the controller causes the No. 2 power mechanism 9 to drive the conveying member 42 to rotate, and drives the spiral conveying structure 422 to rotate. The spiral conveying structure 422 causes the activated carbon particles at the bottom of the No. 1 cylinder 11 to pass through the No. 4 cylinder 41 and enter the No. 1 cylindrical structure 31, so that the activated carbon particles pass through the No. 1 opening 311 and enter the containing chamber.
