Description

Technical Field

[0001] The invention relates to the technical field of vacuum suction roller washing, and in particular to a vacuum suction roller washing device for a papermaking machine. Background Art

[0002] After the pulp is evenly processed in the papermaking process, it needs to be squeezed and the moisture is drained because there is a large amount of moisture in the pulp. The device for removing water from the pulp in the papermaking machine is the vacuum suction roller. The suction holes on the upper surface of the vacuum suction roller are mainly used to form negative pressure to adsorb the roll and prevent it from slipping, and discharge the squeezed moisture through the holes.

[0003] After the vacuum suction roller squeezes the pulp, the squeezed pulp debris is easy to adhere to its surface, resulting in inconvenience in flushing. At the same time, some pulp debris may also enter the inside of the water absorption hole and cause blockage of the water absorption hole, thereby affecting the subsequent papermaking production process. Therefore, if the impurities and debris on its surface are not flushed, it will affect the continued use of the vacuum suction roller. Therefore, the present invention designs a vacuum suction roller flushing device for a papermaking machine to solve the above problems. Summary of the invention

[0014] The beneficial effects of the present invention are as follows:

[0015] 1. This device uses a flushing pipe to perform circular cleaning around the outer surface of the vacuum suction roller body, which can flush away impurities on the outer surface of the vacuum suction roller body to avoid the problem of residual dead corners that cannot be cleaned. At the same time, before cleaning, the rotation of the sponge block inside the scraper component can scrape off the pulp debris and impurities with strong adhesion to the outer surface of the vacuum suction roller body and the surface of the suction hole in advance, avoiding the flushing pipe flushing the outer surface of the vacuum suction roller body. The pulp debris on the surface of the suction hole is not flushed into the inside of the suction hole, which causes the suction hole to be blocked, affecting the subsequent use of the vacuum suction roller body.

[0016] 2. When the sponge block of this device is damaged after working for a long time and needs to be replaced, the lower plate can be rotated around the rotating shaft to make the lower plate and the sponge block disengage, and then a new sponge block can be replaced. The sponge block can be clamped and positioned by the cooperation of the upper plate and the lower plate, so as to avoid the problem that after the sponge block is damaged, it still adheres to the outer surface of the vacuum suction roller to scrape it, thereby reducing the scraping effect.

[0017] 3. During the process of circular cleaning around the outer surface of the vacuum suction roller, the flushing tube will rotate to the bottom of the vacuum suction roller. Therefore, the water used by the flushing tube to clean the vacuum suction roller will fall to the outer surface of the flushing tube again along with impurities and pulp debris under the action of gravity. Therefore, the impurities and pulp debris attached to the surface of the flushing tube can be scraped off by the sliding ring, avoiding the adhesion of some pulp debris to the surface of the flushing tube, which makes the discarded pulp debris unable to be recycled.

[0018] 4. When the ring slides along the outer surface of the flushing tube, the movement of the ball inside the pressure-sensitive component and the cooperation of the spring belts on both sides can squeeze the pressure gauges on both sides to determine where the flushing tube rotates. Only when the flushing tube is in a horizontal position on both sides of the vacuum suction roller body, the ring will slide along the outer surface of the flushing tube. In this way, the impurities scraped off the material can fall from both sides of the vacuum suction roller body instead of falling on the surface of the vacuum suction roller body and the fixed box, which may cause the vacuum suction roller body to fail to clean.

[0019] 5. When the circular ring of this device slides to a certain distance, some impurities and debris will accumulate on its surface and the surface of the flushing pipe. The circular ring drives the push plate to push the stamping plate to move, so that the stamping plate slides along the inside of the stamping box and squeezes the gas inside the stamping box, so that the squeezed gas is sprayed from the air holes on the surface of the stamping box to the upper and lower surfaces of the circular ring and the flushing pipe, and the impurities and paper scraps attached to and accumulated on the surface of the circular ring and the flushing pipe are blown off, so as to prevent the circular ring from leaving impurities and debris on the surface of the flushing pipe during the resetting process, thereby affecting the subsequent flushing of the vacuum suction roller by the flushing pipe.

DETAILED DESCRIPTION

[0029] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. The embodiments of the present invention are provided for the purpose of illustration and description, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiments are selected and described in order to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and thereby design various embodiments with various modifications suitable for specific uses.

[0030] For example, see Figure 1-Figure 4 The present invention provides a technical solution: a vacuum suction roller washing device for a papermaking machine, comprising a support frame 1, a washing mechanism 2 is fixedly connected to the upper surface of the support frame 1, a vacuum suction roller body 3 is fixedly connected to the upper surface of the washing mechanism 2, and an erasing mechanism 4 is fixedly connected to the outer surface of the washing mechanism 2; the support frame 1 provides support for the washing mechanism 2, the vacuum suction roller body 3 and the erasing mechanism 4, the washing mechanism 2 can wash impurities and pulp debris on the outer surface of the vacuum suction roller body 3, and the erasing mechanism 4 scrapes and cleans impurities attached to the internal parts of the washing mechanism 2.

[0031] First, when it is necessary to flush the pulp debris on the outer surface of the vacuum suction roller body 3, the vacuum suction roller body 3 is lifted to the upper surface of the flushing mechanism 2 by an external lifting device. After the vacuum suction roller body 3 is placed, its outer surface is flushed in a circular manner by the flushing mechanism 2.

[0032] The flushing mechanism 2 includes a connecting frame 21, the outer surface of which is fixedly connected to a placement plate 22, a circular rail 23 is fixedly connected to the side of the connecting frame 21 close to the placement plate 22, a slide 24 is rotatably connected to the outer surface of the circular rail 23, a flushing pipe 25 is fixedly connected to the side of the slide 24 close to the placement plate 22, a scraper component 26 is sleeved on the outer surface of the flushing pipe 25, a water inlet pipe 27 is fixedly connected to the outer surface of the flushing pipe 25, a rotating plate 28 is fixedly connected to the end of the water inlet pipe 27 away from the flushing pipe 25, and a water tank 29 is rotatably connected to the outer surface of the rotating plate 28. The placement plate 22 provides support for the vacuum suction roller body 3, the slide 24 can rotate along the outer surface of the circular rail 23, and during the rotation, it will also drive the flushing pipe 25 to rotate around the outer surface of the vacuum suction roller body 3, and flush the outer surface of the vacuum suction roller body 3 through the flushing pipe 25. The water inside the water tank 29 supplies water to the flushing pipe 25 through the water inlet pipe 27 . A water pump is provided inside the water tank 29 to facilitate supplying water into the water inlet pipe 27 and the inside of the flushing pipe 25 .

[0033] The lower surface of the connecting frame 21 is fixedly connected to the upper surface of the supporting frame 1 , the upper surface of the placing plate 22 is fixedly connected to the lower surface of the vacuum suction roller body 3 , and the bottom of the water tank 29 is fixedly connected to the upper surface of the supporting frame 1 .

[0034] After the external hoisting equipment places the vacuum suction roller body 3 on the upper surface of the placement plate 22, the slide 24 rotates along the outer surface of the circular rail 23, and drives the rotation of the flushing pipe 25, the water inlet pipe 27, and the rotating plate 28. The rotating plate 28 can rotate along the inner wall of the water tank 29. A water pump is provided inside the water tank 29 to pump water from the inside of the water tank 29 to the inside of the water inlet pipe 27 and the flushing pipe 25. The flushing pipe 25 can perform circular flushing around the outer surface of the vacuum suction roller body 3 to flush away impurities and pulp debris on the outer surface of the vacuum suction roller body 3, so as to prevent pulp and impurities from remaining on the outer surface of the vacuum suction roller body 3 and affecting its subsequent squeezing effect on the pulp. The circular flushing can flush multiple directions of the outer surface of the vacuum suction roller body 3 to avoid the problem of residual dead corners that cannot be cleaned.

[0035] The scraper component 26 includes a sleeve plate 261, one end of which is fixedly connected to an upper plate 262, a sponge block 263 is slidably connected to the lower surface of the upper plate 262, a lower plate 264 is fixedly connected to the lower surface of the sponge block 263, a rotating shaft 265 is fixedly connected to the inner wall of the lower plate 264, and a rubber rod 266 is fixedly connected to the side of the lower plate 264 close to the rotating shaft 265. The sleeve plate 261 plays a role in fixing and connecting the upper plate 262 and the flushing tube 25, the sponge block 263 is made of soft material and can rotate in contact with the outer surface of the vacuum suction roller body 3, and the upper plate 262 and the lower plate 264 cooperate to clamp and position the upper and lower sides of the sponge block 263.

[0036] The inner surface of the sleeve plate 261 is fixedly connected to the outer surface of the flushing tube 25 , both ends of the rotating shaft 265 are rotatably connected to the inner wall of the upper plate 262 , and one end of the rubber rod 266 away from the lower plate 264 is fixedly connected to the lower surface of the upper plate 262 .

[0037] When the flushing pipe 25 performs circular flushing on the outer surface of the vacuum suction roller body 3, the flushing pipe 25 will also drive the rotation of the sleeve plate 261 and the upper plate 262, the lower plate 264, and the sponge block 263. The sponge block 263 will fit the outer surface of the vacuum suction roller body 3 during rotation, so as to scrape off the pulp debris near the suction hole on the outer surface of the vacuum suction roller body 3 and the pulp debris attached to the outer surface of the vacuum suction roller body 3. First, the outer surface of the vacuum suction roller body 3 is cleaned by the sponge block 263, and then the outer surface of the vacuum suction roller body 3 is rinsed by the water flow sprayed from the flushing pipe 25. Therefore, the scraping effect of the sponge block 263 can, on the one hand, scrape off the pulp with strong adhesion to the outer surface of the vacuum suction roller body 3, and on the other hand, scrape off the pulp debris attached to the outside of the water absorption hole, so as to avoid the flushing pipe 25 from flushing the outer surface of the vacuum suction roller body 3. The pulp debris on the surface of the suction hole is not flushed into the inside of the suction hole, thereby causing the suction hole to be blocked. The sponge block 263 can achieve the effect of early cleaning.

[0038] When the sponge block 263 is damaged by friction after working for a long time, or there are too many impurities attached to the surface, it needs to be replaced. When the sponge block 263 is out of contact with the outer surface of the vacuum suction roller body 3, the lower plate 264 is rotated around the outer surface of the rotating shaft 265 toward the side close to the rubber rod 266. After the lower plate 264 is rotated to a certain angle, the upper surface of the lower plate 264 will be out of contact with the lower surface of the sponge block 263. At this time, the sponge block 263 is taken out from between the upper plate 262 and the lower plate 264, and a new sponge block 263 can be replaced. When the new sponge block 263 is placed between the upper plate 262 and the lower plate 264, the lower plate 264 is released, and the lower plate 264 is reset under the elasticity of the rubber rod 266, and the sponge block 263 is clamped and positioned in cooperation with the upper plate 262.

[0039] For example 2, please refer to Figure 1-Figure 8 The present invention provides a technical solution: on the basis of the first embodiment, the erasing mechanism 4 comprises a fixed box 41, the upper and lower surfaces of the fixed box 41 are fixedly connected with a blowing component 42, the inner surface of the fixed box 41 is slidably connected with a ring 43, the side of the ring 43 close to the fixed box 41 is fixedly connected with a push plate 44, a slider 45 is arranged below the push plate 44, and the lower surface of the slider 45 is slidably connected with a slide rail 46. The ring 43 can slide along the outer surface of the flushing pipe 25 and scrape off the impurities or pulp debris attached to the surface of the flushing pipe 25, and the slider 45 can slide along the surface of the slide rail 46.

[0040] The side of the fixed box 41 close to the flushing pipe 25 is fixedly connected to the side of the sleeve plate 261 away from the upper plate 262 , and the lower surface of the slide rail 46 is fixedly connected to the inner surface of the fixed box 41 .

[0041] During the process of circular flushing of the vacuum suction roller body 3, the flushing tube 25 will rotate to the bottom of the vacuum suction roller body 3 to flush its surface. A part of the flushing water will fall onto the surface of the flushing tube 25. The water contains certain impurities and pulp debris. Therefore, it is necessary to scrape off the impurities and debris on the surface of the flushing tube 25 to prevent the impurities on its surface from falling onto the surface of the vacuum suction roller body 3 again when the flushing tube 25 rotates to the top of the vacuum suction roller body 3.

[0042] Two sliders 45 are provided on the outer surface of the slide rail 46. Both sliders 45 can slide in opposite directions along the outer surface of the slide rail 46. During the sliding process, the sliders 45 can drive the ring 43 to slide along the outer surface of the flushing pipe 25, scraping off impurities and pulp debris that may be attached to the surface of the flushing pipe 25.

[0043] The blowing component 42 includes a stamping plate 421, a pressing spring 422 is fixedly connected to one side of the stamping plate 421, a stamping box 423 is fixedly connected to one end of the pressing spring 422 away from the stamping plate 421, a connecting plate 424 is fixedly connected to the outer surface of the stamping box 423, and a pressure-sensitive component 425 is fixedly connected to one side of the connecting plate 424 away from the stamping box 423. The stamping plate 421 can slide along the inner wall of the stamping box 423, and by squeezing the gas inside the stamping box 423, the squeezed gas can be blown out from the air holes opened on the outer surface of the stamping box 423.

[0044] When the circular ring 43 moves a larger distance, some impurities and pulp debris may fall from the flushing pipe 25 and the surface of the circular ring 43, but there will still be some impurities and pulp debris attached to the upper surface of the flushing pipe 25 and the outer surface of the circular ring 43. Therefore, when the circular ring 43 moves a certain distance, the circular ring 43 can drive the push plate 44 to move, and the push plate 44 pushes the movement of the punching plate 421, so that the punching plate 421 slides along the inside of the punching box 423 and squeezes the gas inside the punching box 423. The squeezed gas is sprayed from the air holes opened on the surface of the punching box 423 to the upper and lower surfaces of the circular ring 43 and the flushing pipe 25, blowing off the impurities attached to the surface. When the circular ring 43 is reset under the drive of the slide 24, the punching plate 421 is also reset under the elasticity of the squeezing spring 422, and slides to its original position along the inner wall of the punching box 423.

[0045] The pressure sensing component 425 includes a pressure sensing box 4251, a rolling ball 4252 is rollingly connected to the inner wall of the pressure sensing box 4251, a pressure measuring device 4253 is fixedly connected to the inner wall of the pressure sensing box 4251, a pressing plate 4254 is slidingly connected to the inner wall of the pressing plate 4254, a limiting rod 4255 is slidingly connected to the inner wall of the pressing plate 4254, and a spring belt 4256 is fixedly connected to the side of the pressing plate 4254 close to the pressure measuring device 4253. The rolling ball 4252 can slide left and right along the inner wall of the pressure sensing box 4251 and squeeze the spring belts 4256 on both sides, and the limiting rod 4255 can limit the rolling distance of the rolling ball 4252 to a certain extent. The spring belt 4256 has the same function as the spring, and both have elasticity and reset functions.

[0046] The outer surface of the stamping plate 421 is slidably connected to the inner surface of the stamping box 423 , the side of the pressure sensing box 4251 close to the stamping box 423 is fixedly connected to the side of the connecting plate 424 away from the stamping box 423 , and both ends of the limiting rod 4255 are fixedly connected to the inner wall of the pressure sensing box 4251 .

[0047] When the ring 43 slides along the outer surface of the flushing tube 25, the impurities and pulp debris attached to the surface of the flushing tube 25 are scraped off by the ring 43. During the scraping process, the ring 43 rotates synchronously with the flushing tube 25. Therefore, when the flushing tube 25 rotates to above the vacuum suction roller body 3, the impurities scraped off by the ring 43 may fall onto the surface of the vacuum suction roller body 3 again. Therefore, it is necessary to make the flushing tube 25 in a suitable position and scrape off the impurities on its surface by the ring 43.

[0048] The fixed box 41 will drive the connection plate 424 and the pressure-sensing box 4251 to rotate during rotation. When the pressure-sensing box 4251 rotates to a horizontal position, the rolling ball 4252 will not roll along the inner wall of the pressure-sensing box 4251. When the pressure-sensing box 4251 is out of the horizontal position and is at an inclined angle, the rolling ball 4252 will roll along the inner wall of the pressure-sensing box 4251 and squeeze any one of the squeezing plates 4254 on both sides, so that the squeezing plate 4254 slides along the inner wall of the pressure-sensing box 4251 and drives the movement of the spring belt 4256, so that the end of the spring belt 4256 away from the squeezing plate 4254 touches the outer surface of the pressure sensor 4253 When extrusion is performed and the pressure sensor 4253 senses the pressure, the surface pressure sensing box 4251 is at an inclined angle. Only when the pressure sensing box 4251 is rotated to a horizontal position, the rolling ball 4252 will be in the middle area inside the pressure sensing box 4251 and will not squeeze the extrusion plates 4254 on both sides. Therefore, when the pressure sensors 4253 on both sides feel extremely small pressure or even no pressure, the ring 43 will slide along the outer surface of the flushing tube 25 to scrape off the impurities on the surface of the flushing tube 25. In this way, the scraped impurities will fall from both sides of the vacuum suction roller body 3 instead of falling on the surface of the vacuum suction roller body 3 and the fixed box 41.

[0049] The specific working process of the present invention is as follows:

[0050] First, the vacuum suction roller body 3 is hoisted to the upper surface of the flushing mechanism 2 by an external hoisting device. After the vacuum suction roller body 3 is placed, the flushing mechanism 2 performs an annular flushing on the outer surface thereof.

[0051] After the external hoisting equipment places the vacuum suction roller body 3 on the upper surface of the placement plate 22, the internal slide 24 of the flushing mechanism 2 drives the flushing pipe 25 to rotate around the outer surface of the vacuum suction roller body 3 to flush it, so that the impurities and pulp debris on the outer surface of the vacuum suction roller body 3 can be flushed off to prevent pulp and impurities from remaining on the outer surface of the vacuum suction roller body 3 and affecting the subsequent squeezing effect on the pulp. The circular flushing can flush multiple directions of the outer surface of the vacuum suction roller body 3 to avoid the problem of residual dead corners that cannot be cleaned.

[0052] During the process of flushing the outer surface of the vacuum suction roller body 3 by the flushing pipe 25, the pulp with strong adhesion to the outer surface of the vacuum suction roller body 3 can be scraped off in advance through the rotation of the sponge block 263 inside the scraper part 26, and the pulp debris attached to the outside of the water absorption hole can be scraped off at the same time, so as to avoid the flushing pipe 25 flushing the pulp debris on the surface of the suction hole into the inside of the suction hole when flushing the outer surface of the vacuum suction roller body 3, thereby causing the suction hole to be blocked, thereby affecting the subsequent use of the vacuum suction roller body 3.

[0053] When the sponge block 263 is damaged by friction after working for a long time, or too many impurities are attached to the surface, it needs to be replaced. The lower plate 264 can be rotated to make the lower plate 264 and the sponge block 263 disengage, and then a new sponge block 263 can be replaced. The upper plate 262 cooperates with the lower plate 264 to achieve the clamping and positioning of the sponge block 263, so as to avoid the problem that the sponge block 263 is still scraping the outer surface of the vacuum suction roller body 3 after being damaged, resulting in a reduced scraping effect.

[0054] During the process of the flushing tube 25 performing circular cleaning around the outer surface of the vacuum suction roller body 3, when the flushing tube 25 rotates to the bottom of the vacuum suction roller body 3, the cleaning water may fall onto the outer surface of the flushing tube 25 again along with impurities and pulp debris. Therefore, the impurities and pulp debris attached to the surface of the flushing tube 25 are scraped off by the sliding ring 43, thereby preventing some pulp debris from adhering to the surface of the flushing tube 25 and making it impossible to recover.

[0055] When the ring 43 slides along the outer surface of the flushing tube 25, the movement of the ball 4252 inside the pressure-sensing component 425 and the cooperation of the spring belts 4256 on both sides can squeeze the pressure gauges 4253 on both sides to determine the position to which the flushing tube 25 rotates. Only when the flushing tube 25 is in a horizontal position on both sides of the vacuum suction roller body 3, the ring 43 will slide along the outer surface of the flushing tube 25. In this way, the impurities scraped off the material can fall from both sides of the vacuum suction roller body 3 instead of falling on the surface of the vacuum suction roller body 3 and the fixed box 41, resulting in the problem of cleaning failure of the vacuum suction roller body 3.

[0056] Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments.
