Description

Technical Field

[0002] With the rapid development of modern industry and the continuous improvement of people's requirements for the quality of living environment, the problem of impurity pollution in the air has received increasing attention. In the process of industrial production, such as chemical, pharmaceutical, electronic manufacturing and other industries, a large amount of waste gas containing various harmful impurities (such as dust, smoke, harmful gases, etc.) will be generated. If it is directly discharged without effective treatment, it will not only cause serious pollution to the surrounding environment, but also endanger human health. In the civilian field, indoor air pollution has also become an important problem. For example, harmful substances such as formaldehyde and benzene released by decoration materials, as well as the intrusion of outdoor polluted air, require efficient air purification equipment to ensure indoor air quality. Traditional air purification equipment has many shortcomings in terms of filtration efficiency, purification stability, and filter cloth replacement and maintenance, and it is difficult to meet the increasingly stringent air quality standards and diversified usage needs.

[0003] Traditional equipment often requires complex disassembly procedures to replace filter cloths, which is time-consuming and laborious. In addition, the filter cloth is prone to problems such as loose fixation and uneven force during use, resulting in damage to the filter cloth or reduced filtering effect. At the same time, due to the lack of an effective filter cloth winding and sorting mechanism, the replaced filter cloth is difficult to reuse, increasing operating costs. For example, the replacement of filter cloths for some large industrial air purifiers requires professional technicians to use special tools to operate, which not only results in long downtime, but also high costs for filter cloth replacement.

[0014] According to another aspect of the present invention, more specifically, an intelligent constant impurity gas purification method, using the intelligent constant impurity gas purification device, comprises the following steps:

[0015] S1. Move the purification device to the area to be purified by using the universal wheels;

[0016] S2, the personnel controls the electric push rod to retract, so that the slip ring slides, and uses the connecting rod to move the cross bar and the drum away from the filter cartridge, so as to create space for the personnel to place the telescopic filter cloth inside the spiral groove, and the spiral groove shields the airway, and controls the cross bar and the drum to reset and fit the surface of the filter cloth;

[0017] S3, the two fans are operated to exhaust air to the outside, so that the inside of the filter cartridge is in a negative pressure state, and the external air is attracted by the negative pressure, passes through the filter cloth, and then enters the airway and the inside of the filter cartridge in turn, and is finally exhausted by the fans, completing the gas circulation filtration;

[0018] S4, and by setting a program, the motor is made to run at a certain time and intermittently. When the motor is running, the gear one and the gear three are rotated through the single-axis dual output, the gear one drives the two gear twos to rotate, and then the two reels are rotated under the drive of the rectangular rod one, one of the reels extends the filter cloth to supply the filter cloth that has not been filtered, and the other reel reels the filter cloth to collect the filter cloth after filtering; at the same time, under the transmission of the gear three, the gear four and the gear ring, the filter drum is rotated so that the filter cloth on its outer side can be moved better, thereby realizing the continuous replacement of the filter cloth after use and maintaining a high-efficiency filtering and purification effect.

[0019] The beneficial effects of the intelligent constant impurity gas purification device and method of the present invention are:

[0020] (1) The present invention adopts a design in which the filter cloth is spirally wound on the outer surface of the filter cartridge, and combines the spiral grooves and air ducts on the filter cartridge to greatly increase the filtration area and the contact time between the air and the filter cloth, thereby effectively improving the filtration efficiency. By controlling the operating power of the fan, a constant purification effect can be accurately achieved, ensuring that the purified air volume that meets the requirements can be stably output under different working conditions, meeting the application scenarios with strict requirements on air quality and flow.

[0021] (2) In the process of winding the filter cloth, the motor drives the gear transmission to rotate the reel to wind up the used filter cloth. At the same time, through the linkage of a series of gears and screws, the slide drives the reel to slide along the rectangular rod, so that the filter cloth is evenly wound on the reel in a spiral form, avoiding the problems of filter cloth folding, uneven tightness, friction with the slide, and excessive pulling due to thickness changes. This is not only conducive to the cleaning and reuse of the filter cloth, but also reduces the damage of the filter cloth caused by improper winding, thereby reducing the operating cost.

[0022] When the drum is disassembled, the fixing of the drum by the limit plate can be easily released by rotating the rotating wheel, which makes it easy to replace the new drum. The entire filter cloth replacement and maintenance setting can greatly improve the operability and maintenance convenience of the equipment.

[0023] (2) The present invention sets a motor as a power source and realizes precise driving and coordinated operation of multiple components such as a reel and a filter cartridge through a combination of multiple gears. It effectively avoids equipment failure caused by uneven force or uncoordinated movement of a single component. When the filter cloth is rolled up, the synchronous rotation of the filter cartridge effectively prevents the filter cloth from being deformed and damaged due to excessive pulling force, thereby improving the stability and reliability of the equipment operation and reducing the maintenance frequency and repair cost of the equipment.

[0037] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments. It should be noted that the embodiments and features in the embodiments of the present application can be combined with each other without conflict.

[0038] In order to make the technical solution of the present invention clearer, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0039] Reference Figure 1-11 , intelligent constant impurity gas purification equipment, including a base 1, two pillars 2 are fixed on the upper surface of the base 1, a filtering mechanism 3 is fixed on the top of the two pillars 2, a positioning mechanism 4 is arranged on the outer surface of the filtering mechanism 3, a support plate 5 is fixed on the right side of the upper surface of the base 1, a motor 6 is fixed on the left side of the support plate 5, a gear 7 is fixed on the left end of the output shaft of the motor 6, the front and rear ends of the gear 7 are meshed and connected with a gear 2 8, the right side of the rear gear 2 8 and the left side of the front gear 2 8 are rotatably connected with a support plate 2 9, the bottom ends of the two support plates 2 9 are fixedly connected with the base 1, a rectangular rod 10 is fixed in the middle of the gear 2 8, and a reel 11 is slidably connected to the outer surface of the rectangular rod 10;

[0040] The filter mechanism 3 includes a filter cartridge 12, the outer surface of the filter cartridge 12 is provided with a spiral groove 13, the inner surface of the spiral groove 13 is penetrated with a plurality of air passages 14, the inside of the air passages 14 is connected with the inside of the filter cartridge 12, the left and right ends of the filter cartridge 12 are rotatably connected with support cylinders 15, the outer surfaces of the two reels 11 are jointly rolled with filter cloth 16, the outer surface of the filter cloth 16 is located inside the spiral groove 13, the support cylinder 15 is rotatably connected with a fan 17, and a constant purification effect is achieved by controlling the operating power of the fan 17, a motor 2 18 is fixed above the outer surface of the support cylinder 15, and the bottom end of the output shaft of the motor 2 18 penetrates into the inside of the support cylinder 15, And it is fixedly connected with the fan 17, and a fixing ring 19 is fixed on the outer surface of the support cylinder 15. The motor 18 is controlled to operate to rotate the fan 17 as needed, so as to control the blowing direction of the fan 17. When the two fans 17 synchronously input external gas into the filter cartridge 12, the gas will pass through the filter cloth 16 from the inside to the outside, so that impurities remain in the filter cartridge 12 and the inner side of the filter cloth 16. When the two fans 17 blow air outward, the negative pressure inside the filter cartridge 12 will attract the external gas through the filter cloth 16 into the filter cartridge 12 through the airway 14 and discharge it, so that the fan 17 outputs the filtered air. The two filtering modes can be adjusted and used according to needs;

[0041] The device spirally wraps the filter cloth 16 around the filter cartridge 12, and then generates airflow through the fan 17 to drive the gas to pass through the filter cloth 16 spirally wrapped around the surface of the filter cartridge 12. The airflow will contact the filter cloth 16; large particles of impurities have greater inertia and are easily intercepted by the filter cloth 16 fibers when the airflow changes direction; smaller particles may diffuse to the filter cloth 16 fibers due to Brownian motion and other reasons and be adsorbed, thereby filtering air impurities;

[0042] By changing the material, pore size and other parameters of the filter cloth 16, it can adapt to different conditions such as air flow rate and impurity concentration, and has strong applicability.

[0043] Reference Figure 2-6 The positioning mechanism 4 includes a slip ring 20, which is located on the outer surface of the support cylinder 15. A plurality of electric push rods 21 are fixed between the slip ring 20 and the fixed ring 19. A plurality of fixed blocks 22 are fixed on the outer surface of the slip ring 20. The outer surface of the fixed block 22 is rotatably connected with a connecting rod 23. The opposite ends of the two connecting rods 23 symmetrically on the left and right are rotatably connected with a cross bar 24. The outer surface of the cross bar 24 is rotatably connected with a roller 25. The outer surface of the roller 25 fits the outer surface of the filter cartridge 12 and the filter cloth 16. Under the limit of the plurality of rollers 25, the filter cloth 16 is prevented from being loosely fixed, loosened, tilted, shifted, etc. under the action of air flow, thereby affecting the filtering effect. By contracting the electric push rod 21, the slip ring 20 is pulled to slide close to the filter cartridge 12, which will push the connecting rod 23. The connecting rods 23 on both sides rotate and move the cross bar 24 and the roller 25 outward, away from the surface of the filter cartridge 12, thereby creating a certain space for personnel to wear a new filter cloth 16.

[0044] Reference Figure 2-4 A gear ring 28 is fixed to the outer surface of the right end of the filter cartridge 12, and the right end of the output shaft of the motor 16 passes through the right side of the support plate 15 and is fixed with a gear three 26. The top of the gear three 26 is meshedly connected with a gear four 27, and the gear four 27 is rotatably connected to the support plate 5, and the gear four 27 is meshedly connected with the gear ring 28. When the motor 16 is operating, the gear ring 28 and the filter cartridge 12 are rotated through the sequential transmission of the gear three 26 and the gear four 27, so as to cooperate with a reel 11 to pull the filter cloth 16 for the winding operation, and also avoid the situation that the reel 11 pulls the winding filter cloth 16 to cause the filter cloth 16 to be pulled excessively and deformed. If the filter cartridge 12 is not driven to rotate by the gear ring 28, when the reel 11 winds up the filter cloth 16, it will pull the filter cartridge 12 to rotate, and the filter cartridge 12 will rotate due to the pulling force of the filter cloth 16, which will generate a certain resistance, so that the filter cloth 16 is subjected to force, which may cause the filter cloth 16 to be damaged.

[0045] Reference Figure 7-11 Two slide grooves 29 are formed through the upper surface of the base 1. A through slot 30 is formed at the left end of the rear slide groove 29 and the right end of the front slide groove 29. A slide 31 is slidably connected inside the slide groove 29. A limit plate 32 is integrally formed on the top of the slide 31. The two limit plates 32 are respectively located on the opposite sides of the two reels 11. Protruding rods 33 are fixed on the opposite sides of the two slides 31. Limiting plates 2 34 and gears 5 35 are fixed on the outer surfaces of the protruding rods 33. Limiting plates 2 34 are fixedly connected with gears 5 35. Gears 6 36 are meshed and connected at the bottom end of gears 5 35. Gears 6 36 are located inside the through slot 30. A rotating drum 37 is fixed on the left end of gears 6. The rotating drum 37 is rotatably connected to the inside of the slide 31. A rectangular rod 2 38 is slidably connected inside the rotating drum 37. Two support plates 42 and two support plates 5 4 are fixed on the lower surface of the base 1. 5. The support plate 42 is close to the slide groove 29. The end of the rectangular rod 238 away from the gear 636 penetrates to the other side of the support plate 42 and is fixed with a worm gear 43. The upper part of the slide 31 is threadedly connected with a screw 41. The upper surface of the base 1 is located on the opposite sides of the two slides 31 and the support plates 39 are fixed. The end of the screw 41 away from the slide 31 penetrates to the other side of the support plate 39 and is fixed with a gear 7 40. The gear 7 40 is meshed with the gear 28. The gear 7 40 is rotatably connected with the support plate 39. The bottoms of the two worm gears 43 are meshed with worms 44. The opposite ends of the two worms 44 penetrate between the two support plates 5 45 and are jointly fixed with a rotating wheel 46. The limiting plate 1 32 and the limiting plate 2 34 are respectively located on both sides of the reel 11, and the opposite sides of the limiting plate 1 32 and the limiting plate 2 34 are respectively in contact with the left and right sides of the reel 11.

[0046] When the motor 16 drives the gear 17 to rotate, and drives the two reels 11 to rotate through the two gear 28 to respectively extend the unused section of the filter cloth 16 and reel in the used section of the filter cloth 16, the gear 7 40 is driven by the gear 28 to drive the screw 41 to rotate, and the rotating screw 41 causes the slide 31, the rotating drum 37, the limit plate 234 and other structures to slide along the slide groove 29 through the thread, and the limit plate 132 pushes the reel 11 to slide along the surface of the rectangular rod 10, so that when the used filter cloth 16 is reeled in, it can be evenly wrapped on the surface of the reel 11 in a spiral form to avoid uneven reeling, resulting in folding of the filter cloth 16, over-feeding and over-tightening, or too thick after reeling, resulting in contact and friction with the slide 31, too thick causing the diameter of the reel to change, resulting in a change in the circumference of one rotation and excessive pulling of the filter cloth 16, etc., and uniform reeling is convenient for subsequent cleaning and processing. The second use; when the reel 11 after winding or putting out the filter cloth 16 is disassembled, the personnel can rotate the rotating wheel 46 to rotate the two worms 44, and under the transmission of the worm wheel 43, the rectangular rod 2 38 drives the rotating drum 37 and the gear 6 36 to rotate, and under the transmission of the gear 5 35, the limiting plate 2 34 rotates and no longer contacts the reel 11, and does not limit and fix it, and the personnel can remove the reel 11 from the rectangular rod 10 and replace it with a new reel 11 for use; when the slide 31 drives the reel 11 to slide, the rectangular rod 2 38 does not move, so that no matter what position the slide 31 moves to, the limiting plate 2 34 can be rotated to release the reel 11 through the rotation of the rectangular rod 2 38; the limiting function of the limiting plate 2 34 is to prevent the reel 11 from shaking when it rotates; Velcro can be set on the surface of the reel 11 as needed to stick and fix the filter cloth 16.

[0047] Reference Figure 1-2 Four universal wheels 47 are provided on the lower surface of the base 1 for moving the device. The universal wheels 47 are driven by a motor and can be adapted to the external air detection system to control the device to move.

[0049] S1. Move the purification device to the area to be purified by the universal wheel 47;

[0050] S2, the personnel controls the electric push rod 21 to retract, so that the slip ring 20 slides, and the cross bar 24 and the roller 25 are moved away from the filter cartridge 12 through the connecting rod 23, so as to create space for the personnel to place the telescopic filter cloth 16 inside the spiral groove 13, and the spiral groove 13 blocks the airway 14, and controls the cross bar 24 and the roller 25 to reset and fit the surface of the filter cloth 16;

[0051] S3, two fans 17 operate to exhaust air to the outside, so that the inside of the filter cartridge 12 is in a negative pressure state. The external air is attracted by the negative pressure, filtered by the filter cloth 16, and then enters the air duct 14 and the inside of the filter cartridge 12 in turn, and is finally discharged by the fan 17, completing the gas circulation filtration;

[0052] S4, and by setting the program, the motor 16 is made to run regularly and intermittently. When the motor 16 is running, the single-axis dual output makes the gear 17 and the gear 3 26 rotate, the gear 17 drives the two gear 2 8 to rotate, and then the two reels 11 rotate under the drive of the rectangular rod 10, one of the reels 11 extends the filter cloth 16 to supply the filter cloth 16 that has not been filtered, and the other reel 11 rolls up the filter cloth 16 to roll up and collect the filter cloth 16 after filtering; at the same time, under the transmission of the gear 3 26, the gear 4 27 and the gear ring 28, the filter cartridge 12 is rotated, so that the filter cloth 16 on its outer side can be better moved, thereby realizing the continuous replacement of the filter cloth 16 after use and maintaining a high-efficiency filtering and purification effect.
