Description

Technical Field

[0001] This utility model relates to the field of drying cylinder roller technology, specifically a high-temperature resistant drying cylinder roller. Background Technology

[0002] A drying cylinder is a piece of machinery used in papermaking to continuously dry paper blanks after pulp has been formed. It is a roller-type pressure vessel with rotatable shafts at both ends, through which steam for drying the paper is introduced. Drying cylinders are generally made of cast iron with a polished outer surface. The presence of many graphite flakes in cast iron allows the paper blank to be easily separated from the cylinder surface, preventing the paper from sticking together during drying. Drying cylinder rollers are used in various industries, including papermaking, textiles, and printing. In the papermaking industry, they are used to dry the moisture in paper to achieve the desired degree of dryness.

[0003] Based on the above, the inventors have discovered the following problem: the current drying cylinder rollers are not convenient to adjust the heating length range of the drying cylinder rollers according to the paper width. When the paper width is less than the heating length range of the drying cylinder rollers, heat is wasted on the surface of the drying cylinder rollers that are not in contact with the paper, thereby reducing the practicality of the drying cylinder rollers.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided a high-temperature resistant drying cylinder roller in order to achieve a more practical purpose. Utility Model Content

[0005] The purpose of this invention is to provide a high-temperature resistant drying cylinder roller to solve the problems mentioned in the background art.

[0006] In view of the above problems, the technical solution proposed by this utility model is as follows:

[0007] A high-temperature resistant drying cylinder roller includes a roller body, which includes a roller shell. The outer wall of the roller shell has several flow holes, and an outer casing is fitted over the roller shell. A first circular plate and a second circular plate are respectively connected to both ends of the roller shell. An adjustment mechanism is provided on the side of the first circular plate away from the roller shell. The adjustment mechanism includes a circular seat, one side of which is connected to the side of the first circular plate away from the roller shell. Sliding grooves are provided on both sides of the inner wall of the circular seat. A connecting plate is slidably connected between a pair of sliding grooves. A stop block is connected to one side of the connecting plate. A screw is connected to the inner sidewall of the circular seat through a bearing. One end of the screw passes through the connecting plate and extends into the interior of the stop block, and is threadedly connected to the stop block. One end of the stop block passes through the first circular plate and the roller shell, and extends into the interior of the roller shell. One end of the stop block is clearance-fitted with the through holes of the first circular plate and the roller shell. Furthermore, a power box is connected to the outer wall of the circular seat, and the end of the screw away from the inside of the abutment extends through the power box into the inside. A rotating shaft is rotatably connected inside the power box away from the screw. Synchronous pulleys are fitted on the outside of both the rotating shaft and the screw, and a synchronous belt is wound between a pair of synchronous pulleys.

[0008] The beneficial effect of adopting the above-mentioned further solution is that by fitting a synchronous pulley around the outside of the screw and the shaft, and winding a synchronous belt between a pair of synchronous pulleys, when the shaft rotates, the synchronous pulley outside the shaft will rotate, and the other synchronous pulley and the screw will rotate under the transmission action of the synchronous belt.

[0009] Furthermore, a motor is provided on the outer wall of the power box, and the output end of the motor is connected to the rotating shaft for transmission.

[0010] The advantage of adopting the above-mentioned further solution is that by setting up a motor, it is easy to drive the shaft to rotate when the motor is working.

[0011] Furthermore, a steam inlet is provided at the center of the side of the roller housing away from the first circular plate, and a connecting pipe is connected to one side of the second circular plate. A solenoid valve is installed on the outside of the connecting pipe, and the steam inlet and the connecting pipe are located on the same axis.

[0012] The beneficial effect of adopting the above-mentioned further solution is that, by using the solenoid valve and the connecting pipe in combination, the solenoid valve is opened first. Since the connecting pipe and the steam inlet are located on the same axis, it is convenient to introduce steam into the interior of the roller housing through the connecting pipe.

[0013] Furthermore, a first hollow ring and a second hollow ring are respectively fitted onto the outside of the first circular plate and the second circular plate. The inner walls of the first hollow ring and the second hollow ring are respectively attached to the outer walls of the first circular plate and the second circular plate, and the opposite sides of the first hollow ring and the second hollow ring are respectively connected to the outer sides of the outer shell.

[0014] The beneficial effect of adopting the above-mentioned further solution is that by connecting the opposite sides of the first hollow ring and the second hollow ring to the outer sides of the outer shell, the first hollow ring, the outer shell, and the second hollow ring can be fitted onto the outside of the first circular plate, the roller shell, and the second circular plate, and the inner walls of the first hollow ring and the second hollow ring are respectively attached to the outer walls of the first circular plate and the second circular plate, so that the inner wall of the outer shell is attached to the outer wall of the roller shell.

[0015] Furthermore, both the first hollow ring and the second hollow ring are provided with a set of slots, and the interior of both sets of slots is rotatably connected with hinge plates. The opposite sides of the two sets of hinge plates are respectively attached to the opposite sides of the first circular plate and the second circular plate.

[0016] The beneficial effect of adopting the above-mentioned further solution is that by opening a set of slots on the first hollow ring and the second hollow ring respectively, and rotatably connecting hinge plates in both sets of slots, when the hinge plates are pushed inward to rotate from the horizontal to the vertical state, the opposite sides of the two sets of hinge plates are respectively attached to the opposite sides of the first circular plate and the second circular plate, thereby limiting the outer shell to the roller shell.

[0017] Furthermore, both the first and second circular plates are provided with two sets of first threaded holes, and both sets of the hinge plates are provided with second threaded holes. The first and second threaded holes are connected by bolts.

[0018] The beneficial effect of adopting the above-mentioned further solution is that, through the cooperation of the first threaded hole, the second threaded hole and the bolt, the two sets of hinge plates are connected to the first circular plate and the second circular plate respectively, thereby realizing the connection of the first hollow ring and the second hollow ring to the first circular plate and the second circular plate respectively, so that the outer shell is stably installed outside the roller shell. When the bolt is removed and the hinge plate is pulled outward, the hinge plate rotates from vertical to horizontal, making it easy for the operator to pull the outer shell to one side, so as to separate the outer shell from the roller shell, thereby replacing the worn outer shell.

[0019] Furthermore, both the roller housing and the outer shell are made of high-chromium cast iron.

[0020] The beneficial effect of adopting the above-mentioned further solution is that by setting the roller housing and outer shell to high-chromium cast iron, which has high temperature resistance and corrosion resistance, the roller housing and outer shell are made resistant to high temperature and corrosion, thereby improving the service life of the roller housing and outer shell.

[0021] Compared with the prior art, the beneficial effects of this utility model are as follows: This high-temperature resistant drying cylinder roller has several flow holes on the outer wall of the roller housing, which facilitates the steam inside the roller housing to contact the outer shell through the flow holes, thereby heating the outer shell and heating the paper sheet running on the surface of the outer shell, thus drying the paper sheet. The first circular plate facilitates the installation of the circular seat, and the circular seat facilitates the installation of the screw. When the screw rotates, the connecting plate and the abutment connected by its external threads can move linearly under the sliding limit action of the connecting plate and the slide groove. When the abutment moves into the roller housing, since one end of the abutment penetrates the first circular plate and the roller housing and is clearance-fitted with the through hole of the first circular plate and the roller housing, the outer wall of the abutment is tightly attached to the inner wall of the roller housing, thereby blocking the flow holes on the outer wall of the roller housing, thus facilitating the adjustment of the heating length range of the outer shell according to the width of the paper.

Detailed Implementation

[0028] 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.

[0029] Please see Figures 1-5This utility model provides a technical solution: a high-temperature resistant drying cylinder roller, including a roller body 100, a roller shell 1001, a plurality of flow holes 1002 on the outer wall of the roller shell 1001, and an outer shell 1003 fitted over the roller shell 1001. A first circular plate 1005 and a second circular plate 1006 are respectively connected to both ends of the roller shell 1001. An adjustment mechanism 200 is provided on the side of the first circular plate 1005 away from the roller shell 1001. The adjustment mechanism 200 includes a circular seat 2001, one side of which is adjacent to the first circular plate 1005 away from the roller. One side of the housing 1001 is connected, and both sides of the inner wall of the circular seat 2001 are provided with sliding grooves 2002. A connecting plate 2003 is slidably connected between a pair of sliding grooves 2002. A stop block 2004 is connected to one side of the connecting plate 2003. A screw 2005 is connected to the inner side wall of the circular seat 2001 through a bearing. One end of the screw 2005 passes through the connecting plate 2003 and extends into the interior of the stop block 2004, and is threadedly connected to the stop block 2004. One end of the stop block 2004 passes through the first circular plate 1005 and the roller housing 1001, and extends into the interior of the roller housing 1001. One end of the stop block 2004 is connected to the roller housing 1001. The first circular plate 1005 and the roller housing 1001 are fitted with a clearance through hole. Several flow holes 1002 are formed on the outer wall of the roller housing 1001, facilitating the contact of steam inside the roller housing 1001 with the outer shell 1003 through the flow holes 1002. This heats the outer shell 1003, thereby heating the paper sheet running on its surface and drying it. The first circular plate 1005 facilitates the installation of the circular seat 2001, which in turn facilitates the installation of the screw 2005. When the screw 2005 rotates, its external threaded connection is easily accessible. The connecting plate 2003 and the abutment 2004 move linearly under the sliding limit action of the connecting plate 2003 and the slide groove 2002. When the abutment 2004 moves into the roller housing 1001, since one end of the abutment 2004 passes through the first circular plate 1005 and the roller housing 1001 and is in clearance fit with the through hole of the first circular plate 1005 and the roller housing 1001, the outer wall of the abutment 2004 is tightly fitted with the inner wall of the roller housing 1001, thereby blocking the flow hole 1002 on the outer wall of the roller housing 1001, so as to facilitate the adjustment of the heating length range of the outer shell 1003 according to the width of the paper.

[0030] 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.

[0031] Please see Figures 1-5 This utility model provides a technical solution: a power box 2006 is connected to the outer wall of a circular seat 2001; one end of a screw 2005, away from the interior of the stop block 2004, extends through the power box 2006 into its interior; a rotating shaft 2007 is rotatably connected inside the power box 2006, away from the screw 2005; synchronous pulleys 2008 are fitted on the outside of both the rotating shaft 2007 and the screw 2005; a synchronous belt 2009 is wound between a pair of synchronous pulleys 2008; a motor 2010 is provided on the outer wall of the power box 2006. The output end of 010 is connected to the rotating shaft 2007 via a transmission connection. By providing a motor 2010, the rotating shaft 2007 can be easily driven to rotate when the motor 2010 is working. A synchronous pulley 2008 is sleeved outside the screw 2005 and the rotating shaft 2007, and a synchronous belt 2009 is wound between the pair of synchronous pulleys 2008. When the rotating shaft 2007 rotates, the synchronous pulley 2008 outside the rotating shaft 2007 will rotate, and under the transmission action of the synchronous belt 2009, the other synchronous pulley 2008 and the screw 2005 will rotate. The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0032] Please see Figures 1-5This utility model provides a technical solution: a steam inlet 1004 is provided at the center of the side of the roller housing 1001 away from the first circular plate 1005; a connecting pipe 1007 is connected to one side of the second circular plate 1006; a solenoid valve 1008 is installed on the outside of the connecting pipe 1007; and the steam inlet 1004 and the connecting pipe 1007 are located on the same axis. A first hollow ring 1009 and a second hollow ring 1010 are respectively fitted on the outside of the first circular plate 1005 and the second circular plate 1006. The inner walls of the first hollow ring 1009 and the second hollow ring 1010 are respectively in contact with the outer walls of the first circular plate 1005 and the second circular plate 1006, and the opposite sides of the first hollow ring 1009 and the second hollow ring 1010 are respectively connected to the outer shell 1006. The outer sides of the 03 are connected. A set of slots 1011 are provided on both the first hollow ring 1009 and the second hollow ring 1010. Hinges 1012 are rotatably connected inside both sets of slots 1011. The opposite sides of the two sets of hinges 1012 are respectively in contact with the opposite sides of the first circular plate 1005 and the second circular plate 1006. Two sets of first threaded holes 1013 are provided on both the first circular plate 1005 and the second circular plate 1006. Second threaded holes are provided on both sets of hinges 1012. Bolts 1014 are threaded between the opposite first threaded holes 1013 and second threaded holes. Both the roller housing 1001 and the outer housing 1003 are made of high-chromium cast iron. Through the cooperation of the solenoid valve 1008 and the connecting pipe 1007, the first... First, open the solenoid valve 1008. Since the connecting pipe 1007 and the steam inlet 1004 are on the same axis, it is convenient to introduce steam into the roller housing 1001 through the connecting pipe 1007. A set of slots 1011 are respectively opened on the first hollow ring 1009 and the second hollow ring 1010, and both sets of slots 1011 are rotatably connected to hinge plates 1012. When the hinge plates 1012 are pushed inward to rotate them from a horizontal to a vertical state, the opposite sides of the two sets of hinge plates 1012 are respectively attached to the opposite sides of the first circular plate 1005 and the second circular plate 1006, thereby limiting the outer shell 1003 on the roller housing 1001. The first threaded hole 1013, the second threaded hole and the bolt 1014 are used in conjunction. This system connects two sets of hinge plates 1012 to the first circular plate 1005 and the second circular plate 1006, respectively, thereby connecting the first hollow ring 1009 and the second hollow ring 1010 to the first circular plate 1005 and the second circular plate 1006, respectively. This ensures that the outer shell 1003 is stably installed outside the roller shell 1001. When the surface of the outer shell 1003 suffers severe friction damage due to prolonged contact with water, acidic chemical slurries, or friction from a high-hardness scraper, the bolt 1014 is removed, and then the hinge plate 1012 is pulled outward, rotating it from vertical to horizontal. This allows the operator to pull the outer shell 1003 to one side, separating it from the roller shell 1001.This allows for the replacement of the worn outer casing 1003. By using high-chromium cast iron for both the roller casing 1001 and the outer casing 1003, which possesses high-temperature and corrosion resistance, the roller casing 1001 and the outer casing 1003 become more resistant to high temperatures and corrosion, thus extending their service life.

[0033] Specifically, the working principle of this high-temperature resistant drying cylinder roller is as follows: During use, through the cooperation of solenoid valve 1008 and connecting pipe 1007, solenoid valve 1008 is first opened. Since connecting pipe 1007 and steam inlet 1004 are located on the same axis, steam is easily introduced into the roller housing 1001 through connecting pipe 1007. A motor 2010 is installed; when motor 2010 is working, it easily drives the rotating shaft 2007 to rotate. Through the connection between screw 2005 and rotating shaft 2007... The shaft 2007 is externally fitted with a synchronous pulley 2008, and a synchronous belt 2009 is wound between the pair of synchronous pulleys 2008. When the shaft 2007 rotates, the synchronous pulley 2008 outside the shaft 2007 will rotate, and under the transmission action of the synchronous belt 2009, the other synchronous pulley 2008 and the screw 2005 will rotate. When the screw 2005 rotates, the connecting plate 2003 and the abutment 2004, which facilitate the external threaded connection, are limited by the sliding limit action of the connecting plate 2003 and the slide groove 2002. To achieve linear movement, when the abutment 2004 moves into the roller housing 1001, one end of the abutment 2004 penetrates the first circular plate 1005 and the roller housing 1001, and is clearance-fitted with the through holes of the first circular plate 1005 and the roller housing 1001. This causes the outer wall of the abutment 2004 to fit tightly against the inner wall of the roller housing 1001, thereby blocking the flow hole 1002 on the outer wall of the roller housing 1001. This facilitates the adjustment of the heating of the outer shell 1003 according to the paper width. Within the length range, when the surface of the outer shell 1003 is severely damaged due to prolonged contact with media such as water and acidic chemical slurries, and the friction with a high-hardness scraper, the bolt 1014 is removed, and then the hinge plate 1012 is pulled outward to rotate it from vertical to horizontal. This allows the operator to pull the outer shell 1003 to one side, separating it from the roller shell 1001, thereby replacing the worn outer shell 1003.
