Description

Technical Field

[0001] This utility model relates to the field of papermaking wire technology, specifically a papermaking forming wire cleaning device. Background Technology

[0002] In the papermaking process, the forming wire is a crucial component of the paper machine, used to hold the pulp and form the wet paper web. As the papermaking process progresses, a large amount of pulp residue, fiber impurities, and other contaminants accumulate on the surface of the forming wire. If not cleaned in time, this will affect the air permeability and filtration performance of the forming wire, thereby impacting paper quality and production efficiency.

[0003] For example, patent CN218478965U discloses a papermaking wire cleaning device, including a vertical plate, a rotating roller rotatably mounted on the inner wall of the vertical plate, a papermaking wire body disposed on the surface of the rotating roller, a cleaning device fixedly mounted on the surface of the vertical plate, the cleaning device including a water pipe fixedly connected to the surface of the vertical plate, a nozzle fixedly mounted on the surface of the water pipe, a collection box disposed directly below the rotating roller, a filter screen slidably mounted on the inner wall of the collection box, a fixed cylinder fixedly mounted on the surface of the collection box, a second magnetic block slidably mounted in the inner wall of the fixed cylinder, and a spring fixedly mounted on the upper surface of the second magnetic block.

[0004] However, in existing equipment, as the proportion of fine fibers in the pulp increases and the amount of functional fillers added increases, impurities such as ink, adhesives, and residual chemicals in the papermaking system are largely trapped and adhered to the wire surface during the dewatering process. These adherents not only clog the filter channels of the wire, leading to a significant decrease in wire filtration efficiency, but also, due to the continuous accumulation of adhesives, form voids and defects during the paper forming stage. In severe cases, this can even cause paper machine breakage accidents, directly disrupting the stability and continuity of production. Furthermore, the cleaning method lacks the ability to spray and clean the wire in real time, failing to remove impurities as soon as they adhere, leading to continuous accumulation of impurities and further exacerbating production problems.

[0005] Therefore, in order to solve such problems, we propose a paper forming wire cleaning device. Utility Model Content

[0006] The purpose of this invention is to provide a paper forming wire cleaning device to solve the problem mentioned in the background art. When using existing devices, as the proportion of fine fibers in the pulp increases and the amount of functional fillers is added, impurities such as ink, adhesives, and residual chemicals in the papermaking system are largely trapped and adhered to the wire surface during the dewatering process. These adherents not only clog the filter channels of the forming wire, leading to a significant decrease in the wire's filtration efficiency, but also, due to the continuous accumulation of adhesives, form voids and defects during the paper forming stage. In severe cases, this can even cause paper machine breakage accidents, directly disrupting the stability and continuity of production. Furthermore, the cleaning method lacks the ability to spray and clean the forming wire in real time, failing to remove impurities as soon as they adhere, leading to continuous accumulation of impurities and further exacerbating the problem of slow production.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a paper forming wire cleaning device, comprising a base and a housing fixedly connected to the top of the base. Slide grooves are provided on both inner walls of the housing. A forming wire body is disposed inside the housing. A double-threaded rod is rotatably connected to the slide groove at the front of the housing. A servo motor is fixedly connected to the right end of the double-threaded rod. Slider blocks are threaded to both ends of the double-threaded rod. A scraper is fixedly connected above and below the inner walls of the sliders. The blade of the scraper abuts against the forming wire body. Circular holes are evenly distributed at the bottom of the scraper. A telescopic rod is fixedly connected inside the circular holes. A return spring is sleeved on the outer wall of the telescopic rod. A guide is fixedly connected to the bottom of the telescopic rod. Friction balls are evenly fixedly connected to the outer wall of the guide.

[0008] Furthermore, mounting grooves are evenly provided on the inner walls of both sides of the shell, and mounting blocks are fixedly connected to the outer walls of both sides of the formed mesh body, and the shell and the mounting blocks are fixedly engaged by the mounting grooves.

[0009] Furthermore, a connecting column is fixedly connected to the outer wall of the scraper, and a telescopic baffle is fixedly connected between the connecting columns.

[0010] Furthermore, a drain pipe is connected through the right outer wall of the housing, a drain valve is installed on the drain pipe, and a guide plate is fixedly connected inside the housing, with the inclined surface of the guide plate facing the drain pipe.

[0011] Furthermore, a water storage tank is fixedly connected to the front of the top shell of the base, a main water pipe is fixedly connected to the top of the water storage tank, a pressure detector is fixedly connected to the outer wall of the main water pipe, a high-pressure water pump is fixedly connected to the top of the main water pipe, and branch water pipes are fixedly connected to both sides of the high-pressure water pump, with the branch water pipes penetrating the outer wall of the shell.

[0012] Furthermore, a nozzle is fixedly connected to the end of the water distribution pipe, and a fixing member is also fixedly connected to the end of the water distribution pipe, with the bottom of the fixing member fixedly connected to the top of the scraper.

[0013] Compared with the prior art, the beneficial effects of this utility model are: a paper forming wire cleaning device, which adopts a novel structural design, the specific details of which are as follows:

[0014] (1) The paper forming wire cleaning device drives the slider through a double threaded rod, which can drive the scraper to precisely scrape the upper and lower surfaces of the forming wire body, effectively removing attached impurities. At the same time, the telescopic rod at the bottom of the scraper can push the guide to fit tightly into the forming wire under the elastic action of the return spring. The friction ball on its outer wall can penetrate into the holes of the forming wire to specifically remove stubborn impurities such as fine fibers, ink, and adhesives. This synergistic effect can effectively prevent the clogging of the forming wire's water filtration channel, prevent the paper from developing hole defects due to the accumulation of impurities during the forming stage, and even cause paper breakage accidents, thereby effectively ensuring the stability and continuity of production.

[0015] (2) The paper forming wire cleaning device consists of a water storage tank, a high-pressure water pump, a water distribution pipe and a spraying system. It is firmly connected to the scraper through a fixing part and can move synchronously with the scraper to achieve real-time and precise rinsing of the forming wire body. It can quickly remove impurities when they just adhere to the wire surface, thus preventing impurities from clogging the water filtration channel and affecting the water filtration efficiency due to continuous accumulation. It effectively prevents production problems from further aggravating and significantly improves the timeliness and thoroughness of cleaning.

[0016] Furthermore, the shell and the forming mesh body are locked together by mounting grooves and mounting blocks. This connection method makes installation and disassembly convenient and efficient, greatly simplifying the maintenance and replacement process of the forming mesh. The guide plate inside the shell can guide the cleaning wastewater to converge into the drain pipe. With the help of the drain valve, the wastewater can be discharged in time, effectively maintaining the cleanliness of the inside of the device. The telescopic baffle connected to the outer wall of the scraper can form a protective barrier during the cleaning process to prevent impurities from splashing and ensure a clean and orderly cleaning environment. The pressure detector on the main water pipe can monitor the water pressure in real time, providing data support for the stable operation of the high-pressure water pump, thereby ensuring the consistency and reliability of the spray cleaning effect.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Example 1: A paper forming wire cleaning device uses a double-threaded rod 13 connected to a slider 131 to horizontally adjust the scrapers 132 on both sides, allowing the scrapers 132 to clean the top and bottom of the forming wire body 121. The device also utilizes the coordinated action of a telescopic rod 14, a return spring 141, a guide 15, and a friction ball 151 to remove impurities from the holes on the forming wire body 121. This prevents impurities such as ink, adhesives, and residual chemicals from being trapped and adhering to the wire surface during the dewatering process, as the proportion of fine fibers in the pulp increases and the amount of functional fillers is added. These adhering substances not only clog the filter channels of the forming wire, significantly reducing the wire's filtration efficiency, but also cause hole defects during the paper forming stage due to the continuous accumulation of adhesives. In severe cases, this can even lead to paper machine breakage, directly disrupting the stability and continuity of production.

[0027] like Figure 1 - Figure 6As shown, a paper forming wire cleaning device includes a base 1 and a housing 11 fixedly connected to the top of the base 1. Slide grooves 111 are provided on both inner walls of the housing 11. A forming wire body 121 is disposed inside the housing 11. A double-threaded rod 13 is rotatably connected to the slide groove 111 at the front of the housing 11. A servo motor is fixedly connected to the right end of the double-threaded rod 13, which can drive the double-threaded rod 13 to rotate. Because the threads at both ends of the double-threaded rod 13 are in opposite directions, it can drive related components to move. Slider blocks 131 are threadedly connected to both ends of the double-threaded rod 13. Under the action of the double-threaded rod 13, the sliders 131 on both sides move. 1. The slider 131 can move in opposite directions within the slide groove 111. Scrapers 132 are fixedly connected above and below the inner walls of the slider 131. As the slider 131 moves, the scrapers 132 can closely adhere to the surface of the formed mesh body 121, efficiently performing scraping operations. The blade surface of the scrapers 132 abuts against the formed mesh body 121. Circular holes are evenly distributed at the bottom of the scrapers 132, and telescopic rods 14 are fixedly connected within these holes. Return springs 141 are sleeved on the outer wall of the telescopic rods 14. Under the elastic force of the return springs 141, the telescopic rods 14 can push the bottom component. A fixed connection is made to the bottom of the telescopic rods 14. Guide member 15, pushed by telescopic rod 14, has friction balls 151 on its outer wall that can fully contact the holes of the forming mesh. Friction balls 151 are evenly fixedly connected to the outer wall of guide member 15. After contacting the holes of the forming mesh, friction is generated by the friction balls 151, thereby deeply removing stubborn impurities in the holes. Mounting grooves 112 are evenly opened on the inner walls of both sides of housing 11. Mounting blocks 12 are fixedly connected to the outer walls of both sides of forming mesh body 121. Housing 11 and mounting blocks 12 are locked together by mounting grooves 112. This locking method not only achieves the stability of the forming mesh, but also... The fixed installation ensures that the forming mesh is accurately fixed during cleaning operations, guaranteeing a stable and efficient cleaning process. A connecting column is fixedly connected to the outer wall of the scraper 132, and a telescopic baffle 16 is fixedly connected between the connecting columns. A drain pipe 18 is connected through the right outer wall of the housing 11, and the sewage generated during cleaning can be discharged through the drain pipe 18. A drain valve 181 is installed on the drain pipe 18. Opening the drain valve 181 can promptly discharge the sewage. A guide plate 17 is fixedly connected inside the housing 11, and the inclined surface of the guide plate 17 faces the drain pipe 18. The sewage flows to the drain pipe 18 under the directional guidance of the guide plate 17.

[0028] Example 2: Unlike Example 1, the water inside the water storage tank 2 is pumped by the high-pressure water pump 23 through the main water pipe 21, the branch water pipe 24 and the nozzle 25 to wash the forming mesh body 121. The water is moved synchronously with the scraper 132 to prevent the cleaning method from lacking the ability to spray and clean the forming mesh in real time. This prevents the impurities from being removed in time when they first adhere to the mesh, which would cause the impurities to accumulate and further aggravate the problem of slow production.

[0029] like Figure 7As shown, a water storage tank 2 is fixedly connected to the front of the top shell 11 of the base 1. The water storage tank 2 is used to store clean water to provide a water source for subsequent cleaning operations. A main water pipe 21 is fixedly connected to the top of the water storage tank 2. The main water pipe 21 is the main channel for clean water transportation and is responsible for transmitting the water in the water storage tank 2 upwards. A pressure detector 22 is fixedly connected to the outer wall of the main water pipe 21. The pressure detector 22 can monitor the water pressure in the main water pipe 21 in real time to ensure that the water supply pressure is within a suitable range. A high-pressure water pump 23 is fixedly connected to the top of the main water pipe 21. The high-pressure water pump 23 provides power for water transportation and can drive the clean water in the water storage tank 2 through the main water pipe. Water is delivered to the distribution pipe 24. Both sides of the high-pressure water pump 23 are fixedly connected to the distribution pipe 24. The distribution pipe 24 receives clean water from the high-pressure water pump 23 and delivers it to the nozzle 25. The distribution pipe 24 penetrates the outer wall of the housing 11. At the same time, the distribution pipe 24 is firmly connected to the scraper 132 with the help of the fixing parts, so that the spraying position can be adjusted synchronously with the movement of the scraper 132. Finally, the clean water is accurately sprayed onto the surface of the forming mesh body 121 through the nozzle 25, realizing the coordinated operation of scraping and rinsing, effectively enhancing the removal effect of impurities on the surface and gaps of the forming mesh, and greatly improving the thoroughness and efficiency of cleaning.
