Description

Technical Field

[0002] Filter paper is a paper product used for filtering, usually made of cotton (wood) fibers, with a loose structure and numerous small holes that allow liquid particles to pass through while blocking larger solid particles. When producing filter paper, pulp is made by adding fibers and hot water in a mixer, the pulp is spread on a paper machine, and the pulp is ground into straight edges on both sides of the spread pulp by a water gun. The water in the pulp seeps out through the paper machine, and a layer of soft paper is obtained.

[0003] In the prior art, after the water gun grinds both sides of the flattened pulp into straight edges, the flushing water sprayed by the water gun is mixed with the polished pulp residue. Usually, a microfilter is used to filter the flushing water, and the pulp residue and the flushing water are separated to achieve the recycling of the pulp residue and the flushing water.

In the description of the present invention, the meaning of "multiple" is two or more, unless otherwise clearly and specifically defined.

[0019] Please also read Figures 1 to 8 The flushing water filtering device for filter paper production provided by the present invention is now described. It includes a machine base 10, a shell 20, a filtering mechanism 30 and a driving mechanism 50; a water collecting pool 11 is provided below the machine base 10, and the water collecting pool 11 is used to collect the separated flushing water; the shell 20 is provided on the machine base 10, and a cavity is provided inside the shell 20, and a drain port connected to the water collecting pool 11 is provided below the shell 20; the filtering mechanism 30 is located in the cavity and is rotatably connected to the shell 20, and the filtering mechanism 30 has a spiral pipe 40, and the two ends of the spiral pipe 40 respectively form a feed port and a discharge port, and the inner diameter of the spiral pipe 40 gradually decreases along the direction from the feed port to the discharge port; the driving mechanism 50 is provided on the machine base 10, and the output end of the driving mechanism 50 is connected to the spiral pipe 40, and is used to drive the spiral pipe 40 to rotate.

[0020] It should be noted that the bottom wall of the base 10 can be provided with legs to make the base 10 suspended in the air, so that there is space for setting a water collection tank 11 under the base 10; the water collection tank 11 is arranged on the ground, located below the base 10, and the water collection tank 11 can collect the flushing water that filters out the filter paper residue, and can be returned to the papermaking machine to supply water to the water gun, so as to realize the reuse of water resources; a cavity is formed in the shell 20, so that the filter mechanism 30 can be installed inside the cavity, and the inner wall of the cavity can block the flushing water separated from the spiral pipe 40, so that the flushing water can flow along the inner wall of the shell 20 to the drain port and enter the water collection tank 11; the filter mechanism 3 0 is rotatably connected to the housing 20, and the spiral pipe 40 is connected to the output end of the driving mechanism 50. The driving mechanism 50 can drive the filtering mechanism 30 to rotate in the cavity, so that the spiral pipe 40 can transport the filter paper residue, and the filter paper residue entering from the feed inlet passes through the spiral pipe 40 and is discharged from the discharge port; the inner diameter of the spiral pipe 40 decreases along the direction from the feed inlet to the discharge port. When the spiral pipe 40 transports the filter paper residue, the conveying space inside the spiral pipe 40 becomes smaller, and the inner wall of the spiral pipe 40 squeezes the filter paper residue, so that the flushing water adsorbed by the filter paper residue seeps out of the filter paper residue, which can increase the recovery amount of the flushing water.

[0021] The beneficial effect of the flushing water filtering device for filter paper production provided by the present invention is that: compared with the prior art, the present invention separates flushing water from filter paper residues through the filtering mechanism 30, and the mixture of flushing water and filter paper residues enters the spiral pipe 40 through the feed port on the spiral pipe 40, and the flushing water is discharged from the drain port below the housing 20, and the filter paper residues are discharged from the discharge port at the other end of the spiral pipe 40. The inner diameter of the spiral pipe 40 near the discharge port is reduced, and the inner wall of the spiral pipe 40 can squeeze the filter paper residues, providing squeezing force to the filter paper residues, so that the flushing water inside the filter paper residues seeps out of the filter paper residues, which can increase the recovery of flushing water and is conducive to the reuse of water resources; and it can improve the drying degree of the separated filter paper residues, reduce the dehydration time of the filter paper residues, and improve production efficiency.

[0022] In one possible implementation, see Figure 2 The spiral pipeline 40 includes a conveying pipe 41, a spiral blade 42 and a rotating shaft 43; the conveying pipe 41 is located in the cavity, rotatably connected to the shell 20, and connected to the output end of the driving mechanism 50, and a feed port and a discharge port are respectively provided at both ends of the conveying pipe 41; the spiral blade 42 is penetrated in the conveying pipe 41 along the axial direction of the conveying pipe 41, and is rotatably connected to the conveying pipe 41; the rotating shaft 43 is connected to the spiral blade 42, and is connected to the output end of the driving mechanism 50.

[0023] It should be noted that the delivery pipe 41 is rotatably connected to the housing 20, and the two ends form a feed port and a discharge port respectively; when the rotating driving member 51 drives the spiral blade 42 to rotate, due to the gravity of the filter paper residue and the friction generated by the inner wall of the delivery pipe 41, the filter paper residue can only move forward along the delivery pipe 41 under the push of the spiral blade 42. The inner wall of the delivery pipe 41 with a gradually decreasing inner diameter can cooperate with the spiral blade 42 that is close to the inner wall of the delivery pipe 41 to squeeze the filter paper residue, provide an extrusion force to the filter paper residue, and make the flushing water inside the filter paper residue seep out of the filter paper residue, which can increase the recovery of the flushing water. The output end of the drive component is connected to the delivery pipe 41 and the spiral blade 42 respectively, so as to avoid the delivery pipe 41 and the spiral blade 42 from rotating in the same direction and at the same speed to affect the delivery of the filter paper residue. The drive component can make the delivery direction of the delivery pipe 41 opposite to that of the spiral blade 42, so that the spiral blade 42 and the delivery pipe 41 are relatively displaced to realize the delivery of the filter paper residue.

[0024] In one possible implementation, see Figure 3 The driving mechanism 50 includes a rotating driving member 51 and a transmission assembly 52. ​​The rotating driving member 51 and the transmission assembly 52 are both arranged on the machine base 10. The output end of the rotating driving member 51 is connected to the transmission assembly 52, and the transmission assembly 52 is connected to the conveying pipe 41 and the rotating shaft 43.

[0025] It should be noted that the rotating drive member 51 can be a motor, which is arranged on the machine base 10. The output end of the rotating drive member 51 is connected to the transmission assembly 52, and the transmission assembly 52 is connected to the rotating shaft 43 and the conveying pipe 41. The conveying pipe 41 is rotatably connected to the shell 20, and the rotating shaft 43 is rotatably connected to the conveying pipe 41. The rotating drive member 51 can drive the conveying pipe 41 and the rotating shaft 43 to rotate together through the transmission assembly 52. ​​The rotating shaft 43 is connected to the spiral blade 42, and can transmit the rotational driving force to the spiral blade 42, so that the spiral blade 42 can rotate inside the conveying pipe 41, thereby achieving the purpose of conveying filter paper residue.

[0026] In one possible implementation, see Figure 4 and Figure 5 A gear ring 33 is provided at one end of the conveying pipe 41, and the transmission assembly 52 includes a transmission wheel 521 and a gear set 522. The transmission wheel 521 and the gear set 522 are both connected to the output end of the rotating driving member 51. The transmission wheel 521 is in transmission connection with the rotating shaft 43. The gear set 522 is located on the side of the transmission wheel 521 away from the rotating driving member 51, and the gear set 522 is meshed with the gear ring 33.

[0027] It should be noted that when the rotary driving member 51 rotates forward, the rotary driving member 51 drives the transmission wheel 521 and the gear set 522 to rotate forward, and the transmission wheel 521 is connected to the rotating shaft 43. The forward rotating transmission wheel 521 drives the rotating shaft 43 to reverse, and the rotating shaft 43 drives the spiral blade 42 to reverse; the rack is provided with internal teeth, and the gear set 522 has two gears, one of which is connected to the output end of the rotary driving member 51, and the other gear is engaged with the internal teeth of the rack. When the rotary driving member 51 rotates forward, the gear set 522 can drive the conveying pipe 41 to rotate forward, so that the rotation directions of the conveying pipe 41 and the spiral blade 42 are opposite, so that the conveying pipe 41 cooperates with the spiral blade 42 to convey the filter paper residue. At the same time, the spiral blade 42 and the conveying pipe 41 rotate in opposite directions at the same time, which can increase the conveying speed of the filter paper residue and improve production efficiency.

[0028] In one possible implementation, see Figure 2 A filter hole array 411 is provided on the wall of the delivery pipe 41 .

[0029] It should be noted that a filter hole array 411 is provided on the wall of the delivery pipe 41. The filter hole array 411 can intercept filter paper residues, so that the filter paper residues remain in the delivery pipe 41, and discharge flushing water through multiple filter hole arrays 411, thereby realizing the separation of flushing water and filter paper residues and increasing the recovery amount of flushing water, which is conducive to the reuse of water resources.

[0030] In one possible implementation, see Figure 6 The filtering mechanism 30 also includes a plurality of cleaning members 31 and a collecting frame 32. Each cleaning member 31 is circumferentially spaced along the extension direction of the conveying pipe 41 on the outer wall of the conveying pipe 41. The collecting frame 32 is disposed on the shell 20, between the cleaning member 31 and the conveying pipe 41. The height of one end of the cleaning member 31 close to the feed port is greater than the height of the other end close to the discharge port.

[0031] It should be noted that, in the process of the conveying pipe 41 cooperating with the spiral blade 42 to squeeze and separate the filter paper residue from the flushing water, part of the filter paper residue enters the housing 20 through the filter hole array 411 under the action of the squeezing force and adheres to the inner wall of the housing 20. The cleaning member 31 is arranged on the outer wall of the conveying pipe 41, and is used to clean the filter paper residue adhered to the inner wall of the housing 20. The number of the cleaning members 31 can be increased according to the degree of crushing of the filter paper residue to improve the cleaning effect of the filter paper residue. The collecting frame 32 is arranged on the housing 20 and is located above the conveying pipe 41, and is located between the cleaning member 31 and the conveying pipe 41; after the cleaning member 31 scrapes off the filter paper residue adhered to the inner wall of the housing 20, it is collected and discharged from the housing 20 through the collecting frame 32 to prevent the scraped filter paper residue from entering the housing 20 again and adhering.

[0032] In one possible implementation, see Figure 2 and Figure 7 The cleaning member 31 includes a hinged rod 311, a scraper 312 and an elastic member 313; the hinged rod 311 is arranged on the outer wall of the conveying pipe 41, and is located at one end of the conveying pipe 41 close to the feed port; one end of the scraper 312 is hinged to the hinged rod 311, and the scraper 312 abuts against the inner wall of the shell 20; the elastic member 313 is arranged on the outer wall of the conveying pipe 41, and is located at one end of the conveying pipe 41 close to the discharge port, and is connected to the bottom wall of the scraper 312.

[0033] It should be noted that one end of the scraper 312 is hinged to the hinge rod 311 on the outer wall of the delivery tube 41, and the other end is connected to the outer wall of the delivery tube 41 through an elastic member 313. The elastic member 313 can be a spring. The elastic member 313 can provide an elastic force for the scraper 312 to abut against the inner wall of the housing 20, so that the scraper 312 can scrape off the filter paper residues adhering to the inner wall of the housing 20 during the rotation of the delivery tube 41. The length of the elastic member 313 can be greater than the length of the hinge rod 311 to adapt to the delivery tube 41 with a gradually decreasing inner diameter, so that the scraper 312 can remain parallel to the setting direction of the housing 20, so that the scraper 312 can be close to the inner wall of the housing 20 to achieve scraping and cleaning of the filter paper residues.

[0034] In one possible implementation, see Figure 7 Two abutting members 21 are spaced apart at the top of the inner wall of the shell 20 , and bristles 22 are provided between the two abutting members 21 . The bristles 22 are used to clean the filter paper residues on the scraper 312 .

[0035] It should be noted that two abutments 21 are provided at intervals at the top of the inner wall of the shell 20, and the connecting surfaces between the two abutments 21 and the inner wall of the shell 20 are smooth transition surfaces, which can ensure that the scraper 312 can smoothly slide through the two abutments 21 when passing through the abutments 21, thereby avoiding the abutments 21 from being stuck with the scraper 312; there are bristles 22 between the two abutments 21, and when the scraper 312 passes through an abutment 21 and is between the two abutments 21, the bristles 22 can remove the filter paper residues adhering to the scraper 312, and can collect the cleaned filter paper residues through the collection frame 32.

[0036] In one possible implementation, see Figure 6 and Figure 7 Baffles 321 are provided on both sides of the collecting frame 32 along the extending direction of the conveying pipe 41 .

[0037] It should be noted that when the filter paper residue falls into the collecting frame 32 for collection, the baffles 321 on both sides of the collecting frame 32 can prevent the filter paper residue from falling into the inner wall of the shell 20, thereby avoiding multiple scraping and cleaning of the filter paper residue on the inner wall of the shell 20; the height of one end of the collecting frame 32 close to the feed port is higher than the height of the other end of the collecting frame 32 close to the discharge port. The filter paper residue collected by the collecting frame 32 can be removed through the end of the collecting frame 32 close to the discharge port, thereby avoiding the filter paper residue from adhering to the inner wall of the shell 20, thereby improving the recycling rate of the filter paper residue.

[0038] In one possible implementation, see Figure 8 A filter plate 23 is provided on the bottom wall of the housing 20. The filter plate 23 is located in the drain outlet and is aligned with the inner wall of the drain outlet.

[0039] It should be noted that a filter plate 23 is provided on the bottom wall of the shell 20, which can intercept the filter paper residues squeezed into the flushing water from the filter hole array 411. When the filter paper residues leave the delivery pipe 41 through the filter hole array 411, some of the filter paper residues will adhere to the inner wall of the shell 20, and some of the filter paper residues will follow the flushing water through the drain port. The filter plate 23 can intercept the filter paper residues on the upper surface of the filter plate 23. The shape of the filter plate 23 matches the shape of the inner wall of the shell 20. When the scraper 312 rotates on the inner wall of the shell 20, the filter plate 23 is prevented from being stuck with the scraper 312. When the scraper 312 passes through the filter plate 23, the filter paper residues intercepted above the filter plate 23 are swept into the collection frame 32, so as to avoid the filter paper residues clogging the filter plate 23 and affecting the discharge of flushing water, thereby increasing the recovery amount of flushing water, and facilitating the recycling of water resources; at the same time, the recycling rate of the filter paper residues can be improved.

[0040] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
