Detailed Implementation

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0023] A structure with automatically switchable filter cotton includes a lower filter box 5, a middle filter box 4 fixedly mounted on the upper side of the lower filter box 5, an upper filter box 3 fixedly mounted on the upper side of the middle filter box 4, a fan cover 2 fixedly mounted on the upper side of the upper filter box 3, a fan fixedly mounted inside the fan cover 2, and an exhaust pipe 1 fixedly mounted on the upper part of the fan cover 2. A filter cotton conveying module is provided inside the lower filter box 5. The filter cotton conveying module includes a conveying component and a filter cotton pressing component. The filter cotton pressing component includes a first fixing seat 13, which is fixedly mounted on both sides of an upper clamping plate 14. The first fixing seat 13 is fixedly connected to the lower filter box 5. On both sides of the filter box 5, a lower clamping plate 17 is provided on the lower side of the upper clamping plate 14. A top plate frame 19 is fixedly provided on the lower side of the lower clamping plate 17. Telescopic rods of electric push rods 15 are fixedly provided on both sides of the top plate frame 19. The outer shell of the electric push rod 15 is fixedly connected to the second fixed seat 16. The second fixed seat 16 is fixedly connected to both sides of the lower filter box 5. The lower clamping plate 17 and the upper clamping plate 14 are inclinedly arranged inside the lower filter box 5. The conveying assembly is installed at both ends of the lower filter box 5. Filter cotton through holes 25 are provided at both ends of the lower filter box 5 corresponding to the positions of the conveying assembly. A sealing ring is provided between the filter cotton through holes 25 and the filter cotton.

[0024] The electric push rod 15 extends and retracts, driving the top plate frame 19 to move up and down, thereby causing the lower clamping plate 17 and the upper clamping plate 14 to move closer or further apart, realizing the pressing and loosening operation of the filter cotton. When the filter cotton is loosened, the conveying component transports the filter cotton into the lower filter box 5. Unused filter cotton is firmly fixed when clamped by the upper clamping plate 14 and the lower clamping plate 17. After the exhaust gas enters the lower filter box 5, the exhaust gas moves upward under the action of the fan, passing through the lower filter box 5, the middle filter box 4, and the upper filter box 3 in sequence. After the exhaust gas enters the lower filter box 5, it will pass through the filter cotton in the filter cotton conveying module. The filter cotton performs filtration. After the filter cotton becomes ineffective, it is released, and the conveying component transports the ineffective part away. The unused filter cotton is transported between the upper clamping plate 14 and the lower clamping plate 17, ensuring that the filter cotton always has good filtration performance, thereby continuously and efficiently filtration the exhaust gas.

[0025] The driving wheel 9 is a roller for winding the used filter cotton, and the driven wheel is a rotating shaft for the filter cotton roll.

[0026] The conveying assembly includes a first outer cover 6 and a second outer cover 10. The first outer cover 6 is installed on the upper part of one side of the lower filter box 5, corresponding to the upper end position of the lower clamping plate 17 and the upper clamping plate 14. The second outer cover 10 is installed on the lower part of the other side of the lower filter box 5, corresponding to the lower end position of the lower clamping plate 17 and the upper clamping plate 14. The driven wheel 7 is detachably installed on the bearing seat of the first outer cover 6, and the driving wheel 9 is detachably installed on the bearing seat of the second outer cover 10. The rotating end of the bearing seat of the second outer cover 10 is fixedly connected to the drive sprocket 8, and the drive sprocket 8 is fixedly connected to the output shaft of the motor. The filter cotton through-hole 25 corresponds to the first outer cover 6 and the second outer cover 10, facilitating the passage of the filter cotton. The first outer cover 6 and the second outer cover 10 respectively include a support base 23 and an upper cover 24. The bearings of the first outer cover 6 and the second outer cover 10 are mounted on the support base 23. The upper cover 24 and the support base 23 are detachably connected. By opening the upper cover 24 of the first outer cover 6 and the upper cover 24 of the second outer cover 10, the driving wheel 9 is mounted on the bearing of the second outer cover 10, and the driven wheel is mounted on the bearing of the first outer cover 6. The outer end of the filter cotton is manually pulled through the upper clamping plate 14 and the lower... Between the clamping plates 17, the outer end of the filter cotton is passed through the corresponding filter cotton through hole 25 and then wound around the drive wheel 9. In use, the filter cotton is clamped by the lower clamping plate 17 moving upward to fix it. When it fails, the lower clamping plate 17 moves downward to release the filter cotton. The motor drives the drive sprocket 8 to rotate, which in turn drives the drive wheel 9 to rotate, pulling the filter cotton to move. The filter cotton drives the driven wheel to rotate, thus releasing the filter cotton. When all the filter cotton between the upper clamping plate 14 and the lower clamping plate 17 is unused, the motor is stopped, and the electric push rod 15 is controlled to drive the lower clamping plate 17 to move upward to clamp the filter cotton.

[0027] The upper clamping plate 14 and the lower clamping plate 17 are frame-shaped.

[0028] A pair of mesh frames 18 are fixedly installed inside the middle layer filter box 4, and filter plates 12 are arranged between the mesh frames 18 in an M-shape. The M-shape saves space, has a large contact area, and facilitates better filtration.

[0029] A granular carbon support mesh 301 is fixedly installed inside the upper filter box 3, and a heat insulation layer is provided on the inner wall of the upper filter box 3. Granular carbon 11 is disposed on the granular carbon support mesh 301. The granular carbon 11 performs further adsorption and filtration.

[0030] A fan is fixedly installed inside the fan casing 2. The air inlet of the fan is fixedly connected to the upper filter box 3, and the air outlet of the fan is fixedly connected to the exhaust pipe 1.

[0031] A maintenance window is provided on one side of the upper filter box 3.

[0032] An air inlet pipe 20 is provided on one side of the lower filter box 5 below the second outer cover 10, and an inspection door 21 and an inspection window 22 are provided on the front side of the lower filter box 5.

[0033] The maintenance window facilitates the replacement of the filter carbon and filter plate 12, which is an M6 filter plate 12.

[0034] The inspection door 21 facilitates maintenance, and the inspection window 22 allows for easy observation of the filter cotton's condition and convenient adjustments at any time.

[0035] The method of using this utility model is as follows: First, ensure that the entire structure of automatically switchable filter cotton is installed and that all parts are securely connected. Open the upper cover 24 of the first outer cover 6 and the upper cover 24 of the second outer cover 10. Install the drive wheel 9 on the bearing of the second outer cover 10 and the driven wheel on the bearing of the first outer cover 6. Manually pull the outer end of the filter cotton through the upper clamping plate 14 and the lower clamping plate 17. After passing the outer end of the filter cotton through the corresponding filter cotton through hole 25, wrap it around the drive wheel 9. Control the electric push rod 15 to drive the lower clamping plate 17 to move upward, so that the lower clamping plate 17 is close to the upper clamping plate 14 and clamps the filter cotton to fix it. At this time, the unused filter cotton is securely fixed between the upper clamping plate 14 and the lower clamping plate 17.

[0036] The exhaust gas is introduced into the lower filter box 5 through the air inlet pipe 20. The fan is turned on and the exhaust gas moves upward under the action of the fan, passing through the lower filter box 5, the middle filter box 4 and the upper filter box 3 in sequence. After entering the lower filter box 5, the exhaust gas passes through the filter cotton in the filter cotton conveying module. The filter cotton performs preliminary filtration of the exhaust gas, and then passes through the filter plate 12 and granular carbon 11. Finally, it is discharged from the exhaust pipe 1 under the action of the fan.

[0037] When the filter plate 12 and granular carbon 11 need to be replaced, the operation can be carried out through the maintenance window on one side of the upper filter box 3; when the filter cotton in the lower filter box 5 needs to be adjusted or replaced, the electric push rod 15 can be controlled to move the lower clamping plate 17 down to release the filter cotton, and then the motor can be turned on. The motor drives the drive sprocket 8 to rotate, and the drive sprocket 8 drives the drive wheel 9 to rotate, pulling the filter cotton to move. The filter cotton drives the driven wheel to rotate, realizing the release of the filter cotton. When all the filter cotton between the upper clamping plate 14 and the lower clamping plate 17 is unused, the motor can be stopped, and then the electric push rod 15 can be controlled to move the lower clamping plate 17 up to clamp the filter cotton.

[0038] During equipment operation, the condition of the filter cotton can be observed through the inspection window 22 on the front side of the lower filter box 5, making it convenient to make adjustments at any time; if the equipment malfunctions, it can be repaired through the inspection door 21.

[0039] The above-disclosed embodiments are merely specific examples of this utility model. However, this utility model is not limited thereto, and any variations that can be conceived by those skilled in the art should fall within the protection scope of this utility model.
