Description

Technical Field

[0001] The invention relates to the technical field of papermaking machines, in particular to a glass panel of a vacuum dehydration box of a papermaking machine. Background Art

[0002] The glass panel of the vacuum dehydration box of the paper machine is one of the key equipment used to separate water from the pulp in the papermaking process. It is usually installed in the dehydration part of the papermaking machine to accelerate the removal of water and the formation of paper. In the papermaking process, after the pulp is stirred and the liquid level is adjusted, it is placed on the glass panel of the vacuum dehydration box. Through the action of external forces such as vacuum suction, most of the water in the pulp is drained through the drainage holes set on the dehydration plate, which can not only quickly dehydrate, but also help control the formation and quality of paper; The defects of the existing glass panel of the vacuum dehydration box of the paper machine are: 1. Patent document CN1017454B discloses a glass panel of a vacuum dehydration box of a paper machine. "It uses glass to replace the widely used polymer materials such as rubber and polyethylene. This greatly reduces the wear of the forming net of the paper machine, prolongs the service life, and improves the product quality. This dehydration panel with glass as the surface material also has the advantages of low cost and easy processing, and is an ideal new material for dehydration panels." However, the glass panel of a vacuum dehydration box of a paper machine in the above-mentioned public document mainly considers reducing the wear of the forming net of the paper machine, prolonging the service life, and improving the product quality, but does not consider the problem of improving the installation stability. Therefore, it is necessary to develop a glass panel of a vacuum dehydration box of a paper machine, which can avoid the occurrence of shaking of the glass panel of the vacuum dehydration box of a paper machine during use through the stability of the installation; 2. Patent document CN209162511U discloses a wear-resistant dewatering panel for the wire section of a paper machine, "including a dewatering structure and a conveying structure, the conveying structure is embedded and movably connected to the upper surface of the dewatering structure, the dewatering structure includes a dewatering box, a dewatering panel and a dewatering base, the dewatering base is fixedly welded to the top of the dewatering box, and the dewatering panels are arranged at intervals on the dewatering base. By arranging a conveying wheel in the device, the dewatering panel rolls in the dewatering base during the dewatering process, and the sliding friction on the dewatering panel when conveying the paper forming net is changed into rolling conveying in contact with the surface of the conveying wheel, so that the high-speed operation During the process, there will be no heat generated due to friction, the friction resistance is reduced, the wear of the dehydration panel and the paper forming net caused by friction is avoided, and it is suitable for the production and use of wear-resistant paper machine net dehydration panel". However, the wear-resistant paper machine net dehydration panel in the above-mentioned public document mainly considers avoiding the wear of the dehydration panel and the paper forming net caused by friction, and does not consider the problem of filtering and purifying the discharged water source. Therefore, it is necessary to study a method that can filter the water source discharged from the glass panel of the vacuum dehydration box of the paper machine, so as to avoid the discharged water source carrying impurities to pollute the environment; 3. Patent document CN210712356U discloses a dewatering scraper for a papermaking machine, "including a base, a transverse sliding adjustment member is provided in the middle of the upper side of the base, the right side of the adjustment member is threadedly connected to a screw rod through a transverse threaded groove, the screw rod is rotatably connected to the scraper housing through a bearing, a scraper is provided on the upper side of the adjustment member, and a ceramic layer is provided on the top of the scraper. The advantage compared with the prior art is that the device can finely adjust the height of the dewatering scraper at will through a handwheel valve, the dewatering scraper is made of corrosion-resistant material as a whole, and adopts an all-in-one structure ceramic layer, which is strong and wear-resistant and can meet the needs of current papermaking dewatering work". However, the dewatering scraper for a papermaking machine in the above-mentioned public document mainly considers the fine adjustment of the height of the dewatering scraper at will, and does not consider the problem of facilitating the replacement of the worn support plate separately. Therefore, it is necessary to develop a structure that is convenient for the support plate to be replaced separately, thereby avoiding the phenomenon of replacing the entire component when it is worn, thereby avoiding waste of resources.

[0012] A method for using a glass panel of a vacuum dehydration box of a papermaking machine, comprising: S1. First, when using the glass panel of the vacuum dehydration box of the paper machine, the position of the frame is fixed by bolts through the mounting plate. After the glass panel of the vacuum dehydration box of the paper machine is installed on the top of the vacuum dehydration box, in order to improve the installation stability of the glass panel of the vacuum dehydration box of the paper machine, after the position of the frame is fixed and installed, the position of the slip ring is moved by rotating the screw rod. When the position of the slip ring moves, the position of the connecting plate is driven to move. When the position of the connecting plate moves, the piston is driven to slide in the cylinder through the driving rod, and then the air inside the first suction cup is extracted, so that the inside of the first suction cup is in a negative pressure state, and then the first suction cup is adsorbed on the top of the vacuum dehydration box, thereby improving the installation stability of the glass panel of the vacuum dehydration box of the paper machine, achieving the purpose of improving the installation stability of the glass panel of the vacuum dehydration box of the paper machine, and avoiding the phenomenon of loosening during use; S2. After fixing the glass panel of the vacuum dehydration box of the paper machine, the support plate is also made of glass, and the top is arc-shaped, which is used to support the forming net of the paper machine, so as to facilitate the sliding position of the forming net of the paper machine. When the forming net of the paper machine moves with the unformed pulp, since the pulp has not dried yet, the water carried will slide and drip on the top of the glass plate, and the water source will flow into the interior of the filter component. The filter screen will filter and purify the water source entering the interior of the filter component. After the purified water source is collected by the water collection tank, it is discharged to the outside through the drain pipe, so as to achieve the purpose of filtering and purifying the water source; S3. When the filter needs to be replaced and cleaned, the position of the limit bolt is rotated so that the limit bolt moves out of the thread groove, and the position of the square frame is no longer limited. The driving spring reset will push the position of the driving plate to move. When the position of the driving plate moves, it will push the position of the square frame to move, and then the square frame will drive the filter to move out of the filter assembly, so that the filter can be cleaned and replaced, so as to facilitate the removal and collection of filtered impurities.

When the support plate is fixed, the glass plate will squeeze the second suction cup, which will cause the inside of the second suction cup to be in a negative pressure state and adsorb on the surface of the glass plate, thus improving the stability of the support plate installation, achieving the purpose of facilitating the replacement of the support plate individually and improving its installation stability. When the support plate is worn out, it can be replaced individually without replacing the glass panel of the vacuum dehydration box of the paper machine as a whole, thus avoiding the waste of materials.

[0013] Furthermore, in step S1, the following steps are also included: S11, the movable groove is rectangular to provide a movable space for the connecting plate, thereby facilitating the movement of the connecting plate and the movement of the driving rod; In step S3, the following steps are also included: S31, when the position of the driving plate moves, the guide ring guides the driving plate so that the driving plate slides vertically; In the step S4, the following steps are also included: S41, the square groove is used to install and fix the position of the second suction cup through the installation block.

After the glass panel of the vacuum dehydration box of the papermaking machine is installed on the upper part of the vacuum dehydration box, in order to improve the installation stability of the glass panel of the vacuum dehydration box of the papermaking machine, after the position of the frame is fixed and installed, the position of the slip ring is moved by rotating the threaded screw. When the position of the slip ring moves, the position of the connecting plate is driven to move. When the position of the connecting plate moves, the piston is driven to slide in the internal position of the cylinder through the driving rod, and then the air inside the first suction cup is extracted, so that the inside of the first suction cup is in a negative pressure state, and then the first suction cup is adsorbed on the upper part of the vacuum dehydration box, thereby improving the installation stability of the glass panel of the vacuum dehydration box of the papermaking machine, achieving the purpose of improving the installation stability of the glass panel of the vacuum dehydration box of the papermaking machine, and avoiding the phenomenon of loosening during use; Second, the present invention is convenient for filtering the water source discharged from the glass panel of the vacuum dehydration box of the paper machine by installing a filter assembly. When the forming net of the paper machine carries the unformed pulp and moves, since the pulp has not dried yet, the water carried will slide and drip on the top of the glass plate, and the water source will flow into the interior of the filter assembly. The filter screen will filter and purify the water source entering the interior of the filter assembly. After the purified water source is collected by the water collection tank, it will be discharged to the outside through the drain pipe to achieve the purpose of filtering and purifying the water source. When the filter screen is replaced and cleaned, the position of the limit bolt is rotated to make the limit bolt move out of the interior of the threaded groove, and the position of the square frame is no longer limited. The driving spring reset will push the position of the driving plate to move. When the position of the driving plate moves, it will push the position of the square frame to move, and then the square frame will drive the filter screen to move out of the interior of the filter assembly, so as to facilitate the cleaning and replacement of the filter screen, thereby achieving the purpose of facilitating the removal and collection of filtered impurities. 3. The present invention facilitates the individual replacement of the support plate used for the glass panel of the vacuum dehydration box of the paper machine by installing a positioning plate and a second suction cup. After the support plate becomes worn, it can be replaced and maintained individually without replacing the entire plate, thereby reducing waste of resources. When the support plate is replaced, the cooperation among the positioning bolts, the positioning plate and the nuts facilitates the fixing of the replaced support plate on the surface of the glass plate. When the support plate is fixed, the glass plate will squeeze the second suction cup, thereby causing the interior of the second suction cup to be in a negative pressure state and adsorbed on the surface of the glass plate, thereby improving the stability of the installation of the support plate, achieving the purpose of facilitating the individual replacement of the support plate and improving its installation stability. When the support plate becomes worn, it can be replaced individually without replacing the entire glass panel of the vacuum dehydration box of the paper machine, thereby avoiding waste of materials.

When the position of the driving plate 20 moves, it will push the position of the square frame 24 to move, and then the square frame 24 will drive the filter screen 25 to move out of the inside of the filter assembly 17, so as to facilitate the cleaning and replacement of the filter screen 25, so as to achieve the purpose of removing and collecting the filtered impurities. After the support plate 4 is worn, , can be replaced and maintained individually without replacing the whole, reducing the waste of resources. When replacing the support plate 4, the cooperation between the positioning bolts 6, the positioning plate 5 and the nuts 7 makes it convenient to fix the replaced support plate 4 on the surface of the glass plate 2. When fixing the support plate 4, the glass plate 2 will squeeze the second suction cup 30, and then the inside of the second suction cup 30 will be called a negative pressure state, adsorbed on the surface of the glass plate 2, improving the stability of the installation of the support plate 4, achieving the purpose of facilitating the replacement of the support plate 4 separately, and improving its installation stability. When the support plate 4 is worn, it can be replaced separately without replacing the glass panel of the vacuum dehydration box of the paper machine as a whole, avoiding waste of materials.

A method for using a glass panel of a vacuum dehydration box of a papermaking machine, applicable to a glass panel of a vacuum dehydration box of a papermaking machine according to any one of claims 1 to 7, characterized in that: include: S1. First, when using the glass panel of the vacuum dehydration box of the paper machine, the position of the frame (1) is fixed by bolts through the mounting plate (3). After the glass panel of the vacuum dehydration box of the paper machine is mounted on the top of the vacuum dehydration box, in order to improve the installation stability of the glass panel of the vacuum dehydration box of the paper machine, after the position of the frame (1) is fixed and mounted, the screw rod (12) is rotated to move the position of the slip ring (11). When the position of the slip ring (11) moves, the position of the connecting plate (10) is driven to move. When the position of the connecting plate (10) moves, the piston (15) is driven to slide in the cylinder (13) through the driving rod (16), thereby extracting the air inside the first suction cup (14), so that the inside of the first suction cup (14) becomes a negative pressure state, and then the first suction cup (14) is adsorbed on the top of the vacuum dehydration box, thereby improving the installation stability of the glass panel of the vacuum dehydration box of the paper machine, achieving the purpose of improving the installation stability of the glass panel of the vacuum dehydration box of the paper machine, and avoiding the phenomenon of loosening during use; S2. After the glass panel of the vacuum dehydration box of the paper machine is fixed, the support plate (4) is also made of glass and has an arc-shaped top, which is used to support the forming net of the paper machine to facilitate the sliding position of the forming net of the paper machine. When the forming net of the paper machine moves with unformed pulp, since the pulp has not yet dried, the water carried by it will slide and drip on the top of the glass plate (2), and the water source will flow into the interior of the filter component (17). The filter screen (25) will filter and purify the water source entering the interior of the filter component (17). The purified water source is collected by the water collection tank (22) and discharged to the outside through the drainage pipe (23), thereby achieving the purpose of filtering and purifying the water source; S3.

The position of the square frame (24) is no longer limited, and the driving spring (19) is reset to push the position of the driving plate (20) to move. When the position of the driving plate (20) moves, the position of the square frame (24) is pushed to move, and the square frame (24) drives the filter (25) to move out of the filter assembly (17), so that the filter (25) can be cleaned and replaced, thereby facilitating the removal and collection of filtered impurities. S4. After the support plate (4) is worn, it can be replaced and maintained separately without replacing the entire plate, thereby reducing waste of resources. When the support plate (4) is replaced, the replaced support plate (4) is conveniently fixed to the surface of the glass plate (2) through the cooperation between the positioning bolt (6), the positioning plate (5) and the nut (7). When the support plate (4) is fixed, the glass plate (2) presses the second suction cup (30), thereby causing the inside of the second suction cup (30) to be in a negative pressure state and adsorbed on the surface of the glass plate (2), thereby improving the stability of the installation of the support plate (4), achieving the purpose of facilitating the replacement of the support plate (4) separately and improving its installation stability. When the support plate (4) is worn, it can be replaced separately without replacing the glass panel of the vacuum dehydration box of the paper machine as a whole, thereby avoiding waste of materials.
