Description

Technical Field

[0001] This invention belongs to the technical field of roller shutter filters, specifically a roller shutter filter for filtering paper fibers. Background Technology

[0002] In the entire papermaking process, the system operates virtually 24 / 7 / 30. Typical fans operate at pressures exceeding 6000 Pa and flow rates of 5000 cubic meters per hour. The inlet temperature of the hot air system is at room temperature, while the temperature in the circulating ducts reaches over 100 degrees Celsius. Furthermore, the high humidity in the hot air system results in a large amount of paper lint and dust being trapped in the ductwork. This paper lint, being numerous and small in size, can clog the ducts if not properly treated, affecting the heating efficiency of subsequent finned radiators and severely clogging nozzles and spray nozzles. This prevents airflow from effectively reaching the paper surface, leading to heat waste and significant energy loss. Therefore, the papermaking industry is traditionally considered a high-pollution, high-energy-consuming sector. Addressing the current technological challenges in papermaking and the problems with existing filtration methods, a specialized paper lint filter has been developed. This device automatically cleans and collects paper lint, eliminating the need for manual cleaning of clogged filters during machine shutdowns and in high-temperature environments. From ensuring smooth daily operation and easy maintenance of the papermaking machine to promoting clean production, energy conservation, and emission reduction for sustainable development in papermaking enterprises, the development and production of this filter has significant implications.

[0003] Traditional papermaking processes generally employ the following methods for filtering paper fibers:

[0004] A. For plate filters, manual cleaning is used. The filter is pulled out from the side of the pipe and then purged with compressed air.

[0005] B. Bag filter: This type of filter uses a high-temperature resistant bag filter to collect paper fibers. It is manually replaced and then discarded after reaching its limit. The disadvantage of using this type of filter is that the high-temperature resistant filter is expensive to manufacture and has high operating costs.

[0006] C. Online reciprocating adsorption filter, which uses a dust collection system to move back and forth to adsorb and clean the paper fibers on the filter cross section.

[0007] However, the above-mentioned filters are widely used in current papermaking waste gas treatment systems, but they all have some defects and shortcomings:

[0008] Plate filters require manual operation. Due to the high paper lint content in the waste gas from the paper industry, the filters are prone to clogging and require frequent replacement, necessitating frequent cleaning and consuming manpower. Customer feedback indicates that manual cleaning is generally required every 4-8 hours. The paper lint removed during manual cleaning spreads throughout the workshop, causing secondary pollution. Furthermore, the high temperatures and scattered paper lint during cleaning create a harsh working environment, posing a significant hazard to operators.

[0009] Bag filters require high-temperature resistant frames and filter fibers, making them up to three times more expensive than ordinary filters, resulting in high long-term operating costs. Furthermore, each replacement requires a complete system shutdown, waiting for the equipment temperature to drop from over 100 degrees Celsius to a level tolerable for personnel before replacement can occur, which is far from meeting the 24-hour uninterrupted operation requirements of customers' papermaking processes.

[0010] While reciprocating adsorption filters do not have the above problems, in actual production, they often need to be cleaned every 30 to 60 minutes. Because of their long cleaning time per cycle, they cannot meet the requirements for high-frequency cleaning. Furthermore, the adsorption effect is not ideal, requiring multiple reciprocating adsorption cycles, which is time-consuming. Increasing the power of the adsorption fan would lead to increased energy consumption and costs.

[0011] In view of this, a roller shutter filter for filtering paper fibers is proposed. Summary of the Invention

[0049] Example 1

[0050] Reference Figure 1 , 2 3, 4, 5, 8, and 9 are the first embodiment of the present invention, which provides a roller shutter filter for filtering paper fibers, including a filter housing 100, a ventilation housing 101, and a storage chamber 102, wherein the storage chamber 102 is configured in two sets, upper and lower, and a support frame 103 is disposed in the ventilation housing 101. A first cover 104 and a second cover 105 are respectively connected to both sides of the storage chamber 102; a paper fiber external cleaning component is disposed in the storage chamber 102, wherein the paper fiber external cleaning component includes... The system includes a lead screw 203, a first traction bar 205, a storage housing 207, a second traction bar 210, and a bearing plate 212. A motor 201 is mounted on the outer wall of a cover 104. A linkage shaft 200 is located at the rotating shaft of the motor 201. A coupling 202 is mounted at the mating position between the linkage shaft 200 and the lead screw 203. In actual use, the bottom of the coupling 202 has a bearing seat located on the inner wall of the storage chamber 102, which is not shown in the design. A lead screw bearing sleeve is threaded onto the outer side of the lead screw 203. 204. The wire bearing sleeve 204 is movably connected to the side of the traction bar 205. A traction seat 206 is provided at the connection point between the wire bearing sleeve 204 and the traction bar 205. A cavity is reserved on the side of the traction seat 206, and a movably connected linkage seat 209 is arranged in the cavity. The storage shell 207 is located at the mirror axis of the two traction bars 205. A brush roller 208 is arranged at the opening of the storage shell 207. The brush roller 208 can remove paper fibers from the outside of the filter screen 218. The brush roller 208 can be equipped with a micro motor on its side, so that the brush roller 208 can rotate autonomously when it moves outside the filter screen 218, thereby improving the paper lint removal effect. The storage shell 207 is hinged to the linkage seat 209. The connection between the storage shell 207 and the traction bar 210 is hinged through the linkage seat 211. The lower part of the bearing plate 212 is movably connected to the upper part of the traction bar 210. The upper part of the bearing plate 212 is connected to the lower part of the top seat 213.

[0051] Example 2

[0052] Reference Figures 4 to 6As shown, this is the second embodiment of the present invention. This embodiment differs from the previous embodiment in that: a support plate 214 is disposed in the storage chamber 102, and an operating port is milled on the side of the support plate 214 to facilitate the movement of the paper lint removal assembly 300. The side of the support plate 214 is aligned with the inner edge of the storage chamber 102. A second motor 215 is mounted on the outer side of the support plate 214, wherein the second motor 215 can be extended and disposed on the outer side of the filter housing 100. An active roller 21 is disposed at the rotating shaft of the second motor 215. 6. The drive roller 216 is linked to the driven roller 217 via a belt. A filter screen 218 is arranged on the outer side of the drive roller 216 and the driven roller 217. A paper lint removal assembly 300 and a paper lint collection assembly 400 are arranged between the drive roller 216 and the driven roller 217. The paper lint removal assembly 300 is located on the inner edge of the cover 104. The function of the paper lint removal assembly 300 is to clean the paper lint on the inner edge of the filter screen 218. The function of the paper lint collection assembly 400 is to collect the cleaned paper lint.

[0053] Furthermore, the distance between corresponding points of traction bar 205 and traction bar 210 is the same, thus ensuring that the storage shell 207 is lifted smoothly upwards. When the screw bearing sleeve 204 is lifted, the storage shell 207 moves upwards on the side of traction bar 205 by means of traction seat 206 and linkage seat 209. When the lower part of the bearing plate 212 is in contact with the position of linkage seat 211, the storage shell 207 can open and deflect. The distance between the upper and lower ends of traction bar 210 is recorded as L1, the distance between the upper and lower ends of traction bar 205 is recorded as L2, and the distance between linkage seat 209 and linkage seat 211 is recorded as L3, where L1+L3=L2. Linkage seat 209 achieves variable lifting movement by means of traction seat 206 and linkage seat 211, and the storage shell 207 achieves opening and deflection by means of traction bar 210 and linkage seat 209.

[0054] Example 3

[0055] Reference Figure 7As shown, this is the third embodiment of the present invention. This embodiment differs from the previous embodiments in that the paper lint removal assembly 300 includes a cylinder 301, a transverse seat 307, and a linkage frame 310. The bottom of the cylinder 301 is equipped with a mounting base that docks with the inner side of the cover 104. A rotating seat 302 is positioned above the cylinder 301, and a linkage bar 303 is hinged to the top of the rotating seat 302. A linkage cavity 304 is pre-reserved on the rotating seat 302 for the normal rotation of the linkage bar 303. A supporting straight cylinder 305 is positioned at one end of the linkage bar 303 away from the rotating seat 302. The linkage bar 303 and the supporting straight cylinder 305 are perpendicularly distributed, with the linkage bar 303 located at the centerline of the supporting straight cylinder 305. The two ends of the supporting straight cylinder 305... All are equipped with an arc-shaped disk 306. A transverse sliding seat 307 is arranged on the side of the arc-shaped disk 306. A groove 308 is reserved at the docking position of the transverse sliding seat 307 and the arc-shaped disk 306. A straight cylinder is arranged on the arc-shaped disk 306 and docked in the groove 308. An arc-shaped groove 309 is milled on the surface wall of the arc-shaped disk 306. The arc-shaped groove 309 is distributed in an arc shape. A straight cylinder is arranged at the end of the transverse sliding seat 307 facing the arc-shaped disk 306 and docked in the arc-shaped groove 309. A linkage frame 310 is hinged to one end of the transverse sliding seat 307. The lower part of the linkage frame 310 is hinged to the side wall of the bearing disk 214. A groove 311 is reserved at the docking position of the linkage frame 310 and the transverse sliding seat 307. A paper scraping pad 312 is docked on the inner edge of the linkage frame 310.

[0056] Furthermore, the paper scraper pad 312 is used to remove paper fibers from the inside of the filter screen 218. The rotating seat 302 is driven by the cylinder 301 to move upwards. During this upward movement, the rotating seat 302 uses the linkage bar 303 to cause the supporting straight cylinder 305 and the arc-shaped disk 306 to rotate. At this time, the horizontal moving seat 307 moves laterally due to the interaction between the second straight cylinder and the arc-shaped groove 309, and the interaction between the first straight cylinder and the first groove 308. Under the action of the second groove 311, the linkage frame 310 and the paper scraper pad 312 move to contact the inner edge surface of the filter screen 218, thereby removing the paper fibers from the inner edge of the filter screen 218. The linkage cavity 304 has a cross-section... The surface is U-shaped. The linkage bar 303, the bearing cylinder 305 and the linkage bar 306 are produced as a set. The arc-shaped disc 306 is produced in pairs to ensure the stability of the linkage frame 310 and the paper scraper pad 312 during movement. The transverse shift seat 307 can move laterally by relying on the groove 308 and the cylinder. The left and right distance of the groove 308 is L4, and the distance from the axis of the bearing cylinder 305 to the arc groove 309 is L5, where L4 = L5. The linkage frame 310 can shake by using the second groove 311 to adjust whether the paper scraper pad 312 contacts the inner edge of the filter screen 218.

[0057] Example 4

[0058] Reference Figure 10 As shown, this is the fourth embodiment of the present invention. This embodiment differs from the previous embodiments in that the paper lint collection assembly 400 includes a motor 401, a transverse shift seat 405, a storage box 408, and a cover 414. A rotating frame 402 is connected to the drive shaft of the motor 401. A rotating frame 403 is connected to the side of the rotating frame 402. One end of the rotating frame 403 is hinged to the support at the bottom of the motor 401. A groove 404 is pre-reserved on the surface of the rotating frame 403. A straight cylinder is positioned at one end of the rotating frame 402 facing the rotating frame 403 and connected to the groove 404. The end of the rotating frame 403, offset from the support, connects to the transverse sliding seat 405 via a docking seat 406. A compression pad 407 is positioned at the end of the transverse sliding seat 405 facing the storage box 408. A groove 409 is pre-formed on the outer side of the compression pad 407. A linkage disc 410 is positioned on the side of the storage box 408. A linkage disc 411 is positioned in the groove 409. A cover 4... 14 is hinged to the storage box 408. The side of the cover 414 is hinged to a connecting strip 415. The side of the connecting strip 415 is equipped with a linkage cylinder 413. The linkage cylinder 413 is externally fitted with a traction strip 412. The traction strip 412 is fixedly connected to the linkage disc 410. The motor 401 controls the rotation of the rotating frame 402. When the rotating frame 402 rotates, it relies on the groove 404 and the hinged relationship between the rotating frame 403 and the support, and uses the connecting seat 406 to cause the transverse moving seat 405 to move. The paper fibers move within the storage box 408, compressing them and converging them towards a corner (a collection box can be placed on the other side of the corner). During this process, the transverse shift seat 405 moves, and the shape of the channel 409 causes the linkage disc 411 to move in conjunction with the linkage disc 410. This, along with the traction bar 412, the linkage cylinder 413, and the connecting bar 415, allows the cover 414 to open, facilitating the collection of paper fibers.

[0059] Furthermore, relying on the rotating frame 402 and the channel 404, the rotating frame 403 can set its range of motion when rotating. Relying on the hinge relationship between the rotating frame 403 and the docking seat 406, the transverse seat 405 can move in the storage box 408. The overall distance of the rotating frame 403 is denoted as L6, and the moving segment of the transverse seat 405 is denoted as L7. L6 = L7. The channel 409 is sloped near the storage box 408, so that when the transverse seat 405 moves, the linkage plate 411 can change its height position in the channel 409.

[0060] It should be understood that numerous specific implementation decisions can be made during the development of any practical implementation, such as in any engineering or design project. Such development efforts may be complex and time-consuming, but for those of ordinary skill in the art who benefit from this disclosure, the development effort will be a routine task in design, manufacturing, and production without requiring extensive experimentation.

[0061] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
