Description

Technical Field

[0001] The invention relates to the technical field of air filtration, in particular to an anti-pollution air filtration device. Background Art

[0002] Since patients in hospitals have low immunity and are easily infected with pathogens, in order to prevent cross-infection between patients from bacteria, viruses and other microorganisms in the air, it is necessary to use anti-pollution air filters that can filter out tiny particles such as dust and pollen in the air to keep the indoor air clean.

[0003] Anti-pollution air filtration devices are primarily used to remove pollutants from the air. Air filters use porous filter materials to capture dust from gas-solid two-phase flows and purify the air. They purify low-dust air before delivering it indoors. During the rainy season, due to frequent and heavy rainfall and high temperatures, moist air easily forms water droplets on the ground, causing the ground and the entire environment to become very humid. However, rising humidity causes dust particles adhering to the filter material to clump together, blocking air circulation and increasing wind resistance. This increases wind pressure loss, reducing wind speed and wind force transmission. Therefore, we propose an anti-pollution air filtration device. Summary of the Invention

[0040] The backflushing assembly 10 is connected to the filter cavity 8 and is arranged at one end of the filter element 7. The backflushing assembly 10 is used to clean the dust in the filter element 7.

[0041] The control component 32 is arranged in the box body 1. When the filter element 7 is backflushed and cleaned, the control component 32 is used to control the time for the detection component 4 to detect the wind resistance of the filter element 7. After the backflushing component 10 completes the cleaning of the filter element 7, if the detection component 4 monitors that the difference in wind resistance on both sides of the filter element 7 is not within the normal value range, the control component 32 extends the backflushing time of the backflushing component 10.

[0042] The detection component 4 includes a placement cavity and a drive cavity 9, both of which are opened in the box body 1. A detection component 1 51 and a detection component 2 52 are provided in the placement cavity, and the detection component 1 51 and the detection component 2 52 are connected in the drive cavity 9. The detection component 1 51 and the detection component 2 52 detect the wind resistance on both sides of the filter element 7. By setting the placement cavity, the detection component 1 51 and the detection component 2 52 can be protected, thereby extending the service life of the detection component 1 51 and the detection component 2 52. The detection component 1 51 detects the wind speed at the air inlet 2 ends, and the detection component 2 52 detects the wind speed after filtration.

[0043] The detection member 51 includes a fan blade 12, which is arranged on one side of the filter element 7, and the fan blade 12 corresponds to the air inlet 2. The fan blade 12 is connected to a rotating rod 18, and the rotating rod 18 is connected to a rotating disk 19. The rotating disk 19 is connected to a number of centrifugal teeth 20, and a damper 21 is connected between the several centrifugal teeth 20 and the rotating disk 19. The centrifugal teeth 20 are connected to the starting member 11. When air enters the air inlet 2, the fan blade 12 is driven to rotate. The rotation of the fan blade 12 can drive the rotating rod 18 to rotate. The rotation of the rotating rod 18 drives the rotating disk 19 to rotate, and then the rotating disk drives the centrifugal teeth 20 to rotate centrifugally, and then the centrifugal teeth 20 are expanded and engaged with the starting member 11, which can trigger the starting member 11. When the fan blade 12 stops rotating, the damper 21 can drive the centrifugal teeth 20 to return to their original position.

[0044] The detection part 2 52 includes a fan blade 2 13, which is arranged on one side of the filter element 7, and the fan blade 2 13 corresponds to the air outlet 3, and is connected to a rotating rod 22, and is connected to a rotating disk 23, and is connected to a plurality of centrifugal teeth 24, and a damper 25 is connected between the plurality of centrifugal teeth 24 and the rotating disk 23, and the centrifugal teeth 24 are connected to the starting member 11, and the fan blade 2 13 can be driven to rotate by the wind filtered by the filter element 7, and the rotation of the fan blade 2 13 can drive the rotating rod 22 to rotate, and the rotating rod 22 can drive the rotating disk 23 to rotate, and the rotation of the rotating disk 23 can drive the centrifugal teeth 24 to rotate centrifugally, thereby making the centrifugal teeth 24 expand and engage with the starting member 11, and thereby triggering the starting member 11, and when the fan blade 2 13 stops rotating, the damper 25 can drive the centrifugal teeth 24 to return to their original position.

[0045] The starting member 11 includes a fixed plate 6, which is connected to the driving chamber 9. T-plate 1 111 and T-plate 2 112 are connected to both sides of the fixed plate 6. Limiting rings 44 are provided on both sides of the fixed plate 6. The limiting rings 44 are used to limit the movement range of the T-plate, and the limiting rings 44 are connected to T-plate 1 111 and T-plate 2 112 respectively. By setting the limiting rings 44, the T-plate 1 111 and T-plate 2 112 can be limited, thereby ensuring that the T-plate 1 111 and T-plate 2 112 work stably. The T-plate 1 111 is engaged with the centrifugal tooth 1 20, and the T-plate 2 1 12 is engaged with the centrifugal tooth 24, the driving chamber 9 is connected to a sliding rheostat 1 27 and a sliding rheostat 2 26, the sliding rheostat 1 27 is connected to a slider 15, the slider 15 corresponds to the T-plate 1 111, the sliding rheostat 2 26 is connected to the slider 2 14, the slider 2 14 corresponds to the T-plate 2 112, the driving chamber 9 is connected to an electromagnet 16, the driving chamber 9 is connected to a slide rail 45, the slide rail 45 is connected to the electromagnet 2 42, and the electromagnet 16 corresponds to the electromagnet 2 42, the electromagnet 16 is electrically connected to the sliding rheostat 1 27, and the electromagnet 2 4 2 is electrically connected to the sliding rheostat 26. The resistance of the sliding rheostat 27 changes to control the magnetic force of the electromagnet 16. The resistance of the sliding rheostat 26 controls the magnet size of the electromagnet 42. A start switch 46 is connected to one side of the electromagnet 42, and the start switch 46 is connected to the drive chamber 9. The fan blade 12 drives the centrifugal tooth 20 to rotate. The centrifugal tooth 20 can drive the T-shaped plate 111 to slide on the fixed plate 6. The T-shaped plate 111 can drive the slider 15 to slide on the sliding rheostat 27. When the sliding rheostat 27 slides to the left, the resistance The larger the value, the smaller the magnetic force of electromagnet 16, and the wind resistance at the air inlet 2 can be detected. The fan blade 2 13 drives the centrifugal tooth 2 24 to rotate, and the centrifugal tooth 24 can drive the T-plate 2 112 to slide on the fixed plate 6, and the T-plate 2 112 can drive the slider 2 14 to slide on the sliding rheostat 2 26. When the sliding rheostat 2 26 slides to the right, the greater the resistance value, and the smaller the magnetic force of electromagnet 2 42, and the opposite surfaces of electromagnet 16 and electromagnet 2 42 repel each other, and then it can be judged whether the filter 7 is blocked according to the resistance value of the sliding rheostat 2 26.

[0046] When the air filter device is started, the air intake volume of the air filter device is the same, and the wind speed at the air inlet 2 is a fixed value, and the magnetic force of the electromagnet 16 is a fixed value. When the filter element 7 is detected to see if it is blocked, if the filter element 7 is not blocked, the magnetic force of the electromagnet 2 42 is equal to or slightly greater than the magnetic force of the electromagnet 16, and the electromagnet 2 42 cannot press the starting element 11. When the filter element 7 is blocked, the rotation speed of the fan blade 2 13 slows down, causing the rotation speed of the rotating rod 2 22 to slow down, and the filter element 7 is blocked. The heart tooth 24 is folded, and the smaller the resistance of the sliding rheostat 26 is, the greater the current is, and the greater the magnetic force of the electromagnet 2 42 is. When the magnetic force of the electromagnet 2 42 is much greater than the magnetic force of the electromagnet 1 16, the electromagnet 1 16 and the electromagnet 2 42 generate a large repulsive force, which triggers the electromagnet 2 42 to slide on the slide rail 45, causing the electromagnet 2 42 to trigger the start switch 46 to start the switch 46, and then the start switch 46 controls the opening of the recoil assembly 10 to perform recoil cleaning on the filter 7.

[0047] Both slider one 15 and slider two 14 are connected to spring one 17. When the filter element 7 needs to be replaced and the air filter device is closed, spring one 17 and spring two 43 can drive slider one 15 and slider two 14 to return to their original positions. A rectangular plate 53 is connected to the driving chamber 9, and a spring six 54 is connected to the rectangular plate 53. The spring six 54 is connected to the electromagnet two 42. When the air filter device is closed, the spring six 54 drives the electromagnet two 42 to return to its original position. When the filter element 7 needs to be replaced, the replaced filter element 7 is re-tested.

[0048] The recoil assembly 10 includes a recoil gas storage barrel 28, which is connected to a heater 29. The heater 29 is used to heat the air in the recoil gas storage barrel 28. By setting the recoil gas storage barrel 28, gas can be stored. When the magnetic force of the electromagnet 2 42 far exceeds the magnetic force of the electromagnet 1 16, and the electromagnet 1 16 and the electromagnet 2 42 generate a repulsive force, the recoil gas storage barrel 28 is opened. By setting the heater 29, the gas in the recoil gas storage barrel 28 can be heated, and then the dust on the filter element 7 can be heated and cleaned, thereby preventing the dust particles on the filter material from sticking together and blocking the air circulation.

[0049] The recoil gas storage barrel 28 is connected to an air supply pipe 30, and the other end of the air supply pipe 30 is connected to a nozzle 31. The nozzle 31 corresponds to the filter element 7. The gas in the gas storage barrel is input into the nozzle 31 through the air supply pipe 30. The nozzle 31 can automatically rotate when impacted by the gas. The electromagnet 16 and the electromagnet 2 42 generate a repulsive force. When the start switch 46 is triggered by the electromagnet 2 42, the recoil gas storage barrel 28 releases gas, and the filter element 7 is recoil-cleaned through the air supply pipe 30 and the nozzle 31, thereby ensuring that the filter element 7 can be cleaned in time.

[0050] Example 2

[0051] The control component 32 includes a connecting plate 34, which is connected to the driving chamber 9. By setting the driving chamber 9, the connecting plate 34 can be protected, thereby extending the service life of the connecting plate 34. A sliding groove 35 is provided on the connecting plate 34, and an electromagnet 4 37 is connected to the sliding groove 35. A connecting rod 36 is connected to the sliding groove 35, and the electromagnet 4 37 is sleeved on the connecting rod 36, so that the electromagnet 4 37 can be slidably connected on the connecting rod 36 to limit the electromagnet. One end of the electromagnet 4 37 is connected to a sealing plate 1 38, and the sealing plate 1 38 is slidably connected to the sliding groove 35. By setting the sliding groove 35, the sealing plate 1 38 can be limited, and the electromagnet 4 37 can be limited. The sealing plate 1 38 fits with the sliding groove 35, thereby forming a negative pressure chamber, thereby preventing the electromagnet 4 37 from deflecting during movement. The sealing plate 1 38 is sleeved on The spring 39 is connected to the connecting rod 36 and the sealing plate 38, and the sliding groove 35 is connected to the pressure switch 40. The pressure switch 40 is used to control the closing of the recoil gas storage barrel 28. A through hole 33 is opened at one end of the sliding groove 35. When the magnetic force of the electromagnet 2 42 far exceeds the magnetic force of the electromagnet 16, the electromagnet 4 37 is activated, and the electromagnet 4 37 moves on the connecting rod 36, thereby driving the sealing plate 38 to move in the sliding groove 35. The gas in the sliding groove 35 is discharged through the through hole 33, and then when the sealing plate 38 triggers the pressure switch 40, the recoil assembly 10 is closed. Since the aperture of the through hole 33 is small, the gas cannot pass through the through hole 33 quickly when squeezed by the sealing plate 38, and the gas is discharged slowly through the through hole 33, which can extend the working time of the recoil gas storage barrel 28, and thus can control the nozzle head 31 to have enough time to recoil the filter element 7.

[0052] The connecting rod 36 is provided with a through hole 2 41, and the electromagnet 4 37 is provided with two grooves 47, and the two grooves 47 are connected to the through hole 2 41, and the two grooves 47 are connected to the spring 4 50, and the two springs 4 50 are commonly connected to the drive plate 55. By setting the groove 47 and the drive plate 55, the spring 4 50 can be limited and fixed, thereby preventing the spring from deflecting during operation. By setting the spring 2 43, the drive plate 55 can be supported, thereby ensuring that when the electromagnet 4 37 slides on the connecting rod 36, the drive plate 55 is in the through hole 2 41. It moves stably, and the driving plate 55 passes through the through hole 2 41 and is connected to the two grooves 47. The sealing plate 2 49 is connected to the through hole 2 41, and the sealing plate 2 49 fits with the through hole 2 41, thereby forming a negative pressure chamber. A spring 511 is connected between the sealing plate 2 49 and the through hole 2 41. A pressure switch 2 522 is connected to the through hole 2 41, and a through hole 3 48 is opened on the through hole 2 41, and the through hole 3 48 passes through the connecting plate 34. An electromagnet 3 321 is provided at the corresponding position of the electromagnet 4 37, and the opposite surfaces of the electromagnet 3 321 and the electromagnet 4 37 repel each other.

[0053] When the magnetic force of electromagnet 2 42 far exceeds the magnetic force of electromagnet 1 16, it starts and is in a recoil state. Subsequently, electromagnet 4 37 and electromagnet 3 321 are started at the same time. Electromagnet 4 37 and electromagnet 3 321 generate relative repulsive forces, driving the driving plate 55 to move in the through hole 2 41, and then the driving plate 55 presses against the sealing plate 2 49. The gas behind the driving plate 55 is discharged through the through hole 3 48. The driving plate 55 pushes the sealing plate 2 49 to slide at the same time. However, due to the small diameter of the through hole 3 48, the gas cannot be discharged from the through hole 3 48 quickly, and the sealing plate 2 49 cannot be directly pushed to the through hole 3 48. At this time, it will be squeezed by the sealing plate 2 49. , here is a single extrusion. After the magnetic force disappears, the sealing plate 2 49 will not be reset directly due to the action of the through hole 3 48, but will be reset slowly. If there is a moist obstruction adhering to the filter element 7, the electromagnet 1 16, the electromagnet 2 42, the electromagnet 3 321 and the electromagnet 4 37 will repeat the above action, and then continue to push the sealing plate 2 49 when the sealing plate 2 49 is not reset in time, until the sealing plate 2 49 is pushed to the squeeze pressure switch 2 522 after multiple pushes. At this time, under the action of recoil, the heater 29 is started at the same time to heat the recoil airflow to realize the heated recoil function, drying the moist obstruction while recoil, and facilitating the removal of the moist obstruction.
