Description

Technical Field

[0001] The present invention relates to the technical field of fiber separators, in particular to a fixed plate and a fiber separator. Background Art

[0002] The fiber separator is a papermaking wood chip fiber processing equipment. It uses the difference in specific gravity between wood chip fibers and impurities to remove light and heavy impurities in wood chip fiber raw materials. It also has the function of debonding and screening. The fiber separator uses high-speed centrifugal force to separate heavy debris, fibers and light debris into layers due to different specific gravities, and pushes them forward through the hydraulic pressure generated by the rotation of the impeller for separation.

[0003] The fixed plate is an important component of the fiber separator. It works with the rotor and plays a vital role in the separation effect and stability of the fiber separator. Due to design defects, the existing fixed plate has a large gap between it and the cavity, and the sealing performance is poor, which affects the separation effect. In addition, the weight of the fixed plate is too large, and the fixing method in the cavity is unstable, which makes the fixed plate easy to shift during operation and touch the rotor, resulting in loss of dynamic balance, causing abnormal shaking of the whole machine, howling and metal friction sound, and finally leading to emergency shutdown, affecting the service life of the fiber separator.

DETAILED DESCRIPTION

[0032] In order to more clearly understand the technical means of the present invention and implement it according to the contents of the specification, the specific implementation methods of the present invention are further described in detail below in conjunction with the drawings and examples. The following examples are used to illustrate the present invention but are not used to limit the scope of the present invention.

[0033] The present invention provides a fiber separator (not shown). The fiber separator includes a slurry inlet, a slurry outlet, and a cavity arranged between the slurry inlet and the slurry outlet, wherein a rotor and a fixed plate 100 are arranged in the cavity. The rotor rotates at high speed to separate and screen the fiber slurry. The fixed plate 100 is arranged in the middle of the rotor to separate the cavity into a suction chamber and a separation chamber. In addition, the fixed plate 100 can provide the rotor with necessary structural support and working interface to ensure that the rotor maintains the correct position and dynamic balance when rotating at high speed.

[0034] Please continue reading Figures 1 to 9 As shown, the fixed plate 100 includes a shell 10 and a plurality of telescopic connection blocks 20 disposed in the shell 10. The plurality of telescopic connection blocks 20 can pass through the avoidance opening 131 on the shell 10 to abut against the cavity of the fiber separator, thereby fixing the fixed plate 100 in the cavity and dividing the cavity into a suction cavity and a separation cavity.

[0035] The housing 10 includes a top plate 11 and a bottom plate 12 that are arranged opposite to each other, and an outer plate 13 and an inner plate 14 that are arranged between the top plate 11 and the bottom plate 12. A hollow receiving chamber 15 is formed between the top plate 11, the bottom plate 12, the outer plate 13 and the inner plate 14. A plurality of telescopic connection blocks 20 are arranged in the receiving chamber 15, and a avoidance opening 131 is arranged at a position corresponding to the telescopic connection block 20 of the outer plate 13. The telescopic connection block 20 is configured to at least partially pass through the avoidance opening 131 to abut against the cavity of the fiber separator. By providing the hollow receiving chamber 15, the material usage of the fixed plate 100 is reduced, thereby reducing the overall weight of the fixed plate 100, and reducing the manufacturing cost, reducing the operating burden of the fiber separator, and improving the energy efficiency of the fiber separator.

[0036] By arranging a plurality of telescopic connection blocks 20 in the receiving cavity 15, the telescopic connection blocks 20 can pass through the avoidance opening 131 on the outer plate 13 to abut against the cavity of the fiber separator, thereby making the connection between the fixed plate 100 and the cavity of the fiber separator more stable. In addition, the arrangement of the telescopic connection blocks 20 allows the telescopic connection blocks 20 to be retracted into the receiving cavity 15 when the fixed plate 100 is installed, flush with the outer wall, so that the fixed plate 100 can be easily installed in the gap of the rotor. In addition, the arrangement of the telescopic connection blocks 20 can allow fine-tuning to a certain extent to facilitate adaptation to different cavities, thereby improving the adaptability and reliability of the fixed plate 100. In addition, the telescopic connection blocks 20 can pass through the special avoidance opening 131 on the outer plate 13 to abut against the cavity, and this design helps to improve the sealing between the fixed plate 100 and the cavity. Good sealing performance can prevent the leakage of fibers and impurities, and ensure the efficiency and quality of the separation process. By reducing the weight of the fixed plate 100 and improving the connection method between the fixed plate 100 and the cavity, it helps to improve the dynamic balance of the fiber separator, reduce vibration and noise during operation, improve the stability and safety of equipment operation, reduce maintenance costs and replacement frequency, and extend the service life of the fiber separator.

[0037] Please continue reading Figures 1 to 6 As shown, the top plate 11 and the bottom plate 12 are both annular thin plates, and the thickness thereof is about 8 to 15 mm.

[0038] Optionally, in the present embodiment, the top plate 11 is two semicircular thin plates, and the two semicircular thin plates are fixedly connected by the first locking member 16. That is, by welding the first locking member 16 to the two semicircular thin plates, the fixed plate 100 becomes a complete circular thin plate. Similarly, the bottom plate 12 is also two semicircular thin plates, which are formed into a complete circular thin plate by the second locking member 17. Of course, in other embodiments, the top plate 11 and the bottom plate 12 can also be designed as complete circular thin plates, or designed as multiple segments, which are connected and fixed by the connecting structure or the first locking member 16 and the second locking member 17.

[0039] An inner plate 14 and an outer plate 13 are welded between the top plate 11 and the bottom plate 12, so that the fixed plate 100 as a whole presents a hollow cavity cylinder with a thickness of about 100 mm and a diameter of about 1000 mm. With such an arrangement, the original fixed plate 100 can be improved from a machined thick plate to a welded sheet metal part, which greatly reduces the weight. Optionally, the weight of the fixed plate 100 of the present invention can be reduced to 1 / 3 of the weight of the original fixed plate 100, thereby reducing the material usage of the fixed plate 100, thereby reducing the overall weight of the fixed plate 100, and reducing the manufacturing cost, reducing the operating burden of the fiber separator, and improving the energy efficiency of the fiber separator. In addition, the weight reduction also makes it easier to install it to the center of the rotor, improving the convenience of installation.

[0040] Please continue reading Figure 5 and Figure 6 , and combined with Figures 1 to 4 As shown, the top plate 11 is provided with a first locking member 16, and the bottom plate 12 is correspondingly provided with a second locking member 17, and the top plate 11 and the bottom plate 12 are detachably connected through the first locking member 16 and the second locking member 17. Such a configuration makes it easy to disassemble the fixed plate 100 structure, so as to facilitate maintenance and replacement (for example, replacing the internal telescopic connection block 20 and other structures or replacing the top plate 11 and the bottom plate 12), thereby reducing maintenance costs.

[0041] Furthermore, at least one first locking member 16 is provided on the top plate 11. In the present embodiment, two first locking members 16 are provided, and the two first locking members 16 are respectively welded to the top plate 11. Moreover, the two first locking members 16 are symmetrically arranged around the center of the top plate 11. Such arrangement provides better balance and stability. Moreover, the two first locking members 16 can make the connection of the top plate 11 more stable, and at the same time make the connection between the top plate 11 and the bottom plate 12 more stable. Of course, in other embodiments, one or more first locking members 16 can also be provided, and the present invention is not limited thereto.

[0042] Correspondingly, at least one second locking member 17 is also provided on the bottom plate 12. In this embodiment, two second locking members 17 are also provided, and the two second locking members 17 are respectively welded to the bottom plate 12. In addition, the two second locking members 17 are symmetrically arranged around the center of the bottom plate 12. Such arrangement provides better balance and stability. In addition, the two first locking members 16 can make the connection of the bottom plate 12 more stable, and at the same time make the connection between the top plate 11 and the bottom plate 12 more stable. Of course, in other embodiments, one or more second locking members 17 can also be provided, and the present invention is not limited to this.

[0043] Further, one of the first locking member 16 and / or the second locking member 17 is provided with a threaded hole, and the other is provided with a countersunk hole or a threaded hole corresponding thereto. Fasteners, such as screws, etc., can be inserted into the threaded hole and the countersunk hole, thereby realizing a detachable connection between the top plate 11 and the bottom plate 12.

[0044] Furthermore, both the first locking member 16 and the second locking member 17 are provided with step portions, and the two step portions abut against each other, so that the first locking member 16 and the second locking member 17 are staggered, thereby improving the stability of the connection between the top plate 11 and the bottom plate 12.

[0045] Furthermore, the first locking member 16 is provided with a first positioning member 161, and the second locking member 17 is correspondingly provided with a second positioning member 171. The first locking member 16 and the second locking member 17 are quickly positioned and connected through the first positioning member 161 and the second positioning member 171 to prevent misalignment and achieve quick installation.

[0046] In this embodiment, one of the first positioning member 161 and the second positioning member 171 is a positioning hole, and the other is a positioning column. In other embodiments, the first positioning member 161 and the second positioning member 171 may also be other structures.

[0047] See also Figure 7 , and combined with Figure 2 and Figure 3 As shown, a plurality of telescopic connecting blocks 20 are arranged in the accommodating cavity 15 of the outer shell 10, and the telescopic connecting blocks 20 can pass through the avoidance opening 131 on the outer plate 13 to abut against the cavity of the fiber separator, thereby making the connection between the fixed plate 100 and the cavity of the fiber separator more stable, and various parts of the outer wall of the fixed plate 100 can maintain the same gap with the cavity, thereby stabilizing the airflow and helping to improve the dynamic balance of the fiber separator.

[0048] Furthermore, the extension lines of the plurality of telescopic connection blocks 20 intersect at a central point, and the plurality of telescopic connection blocks 20 are uniformly radially arranged with the central point as the center of the circle. In this way, the plurality of telescopic connection blocks 20 are uniformly distributed in the receiving cavity 15 of the housing 10 to balance the stress and reduce the local stress concentration, thereby improving the durability and reliability of the entire structure, optimizing the dynamic balance of the entire fiber separator, and reducing vibration and noise.

[0049] In this embodiment, six telescopic connection blocks 20 are disposed in the receiving cavity 15 of the housing 10. The six telescopic connection blocks 20 are evenly radiated from the center of the housing 10 in the receiving cavity 15. In other embodiments, other numbers of telescopic connection blocks 20 may be designed as required.

[0050] The telescopic connection block 20 includes a slider end 21 and a connecting rod 22 connected to the slider end 21. The slider end 21 can be at least partially exposed in the avoidance opening 131 on the outer wall to abut against the cavity of the fiber separator. Through the setting of the telescopic connection block 20, it is convenient to install the fixed plate 100 in the rotor, and at the same time, it is convenient to fix the fixed plate 100 in the cavity, thereby improving the connection stability and balance between the fixed plate 100 and the cavity. In addition, since at least part of the slider end 21 is still located in the avoidance opening 131, it can play a good sealing role, thereby effectively isolating the suction chamber and the separation chamber.

[0051] Furthermore, a positioning protrusion 211 is provided on the side of the slider end 21 away from the connecting rod 22. A positioning groove is provided in the cavity of the fiber separator at a position corresponding to the positioning protrusion 211. By providing the positioning protrusion 211 and the positioning groove, the fixed plate 100 can be quickly installed in the cavity, realizing a foolproof design. In addition, the positioning protrusion 211 and the positioning groove can also improve the connection stability between the fixed plate 100 and the cavity.

[0052] Furthermore, the outer surface of the positioning protrusion 211 is an arc-shaped surface, and the curvature of the arc-shaped surface is the same as or similar to the curvature of the housing 10, thereby improving the sealing performance between the telescopic connecting block 20 and the cavity.

[0053] Furthermore, in the present embodiment, the connecting rod 22 is a screw provided with threads. Through the active connection between the connecting rod 22 with threads and the embedded adjustment member 30, the position of the slider end 21 can be conveniently adjusted, so that the slider end 21 can be telescopically connected to the avoidance opening 131. Of course, in other embodiments, the telescopic connecting block 20 can also be movably connected to the avoidance opening 131 of the housing 10 in other ways. For example, in the form of a sleeve and a telescopic rod, or by setting a locking structure, etc., the present invention is not limited to this.

[0054] See also Figure 8 Combined with the diagram Figure 2 , Figure 3 and Figure 7 As shown, the fixed plate 100 further includes an embedded adjustment member 30 disposed in the receiving cavity 15. The number of the embedded adjustment members 30 is arranged in a one-to-one correspondence with the telescopic connection block 20. The position of the telescopic connection block 20 can be effectively adjusted by the embedded adjustment member 30.

[0055] Furthermore, the embedded adjustment member 30 includes a support member 31 and at least one fixing member 32. The support member 31 is used to provide support for the connecting rod 22, and the position of the slider end 21 is adjusted and fixed to the installation position by the tightness of the fixing member 32.

[0056] Specifically, the support member 31 includes a first wall 311 facing the slider end 21, a second wall 312 away from the slider end 21, and at least one separation wall 313 disposed between the first wall 311 and the second wall 312. That is, the support member 31 is a partition-type cubic structure.

[0057] In this embodiment, there is only one separation wall 313, and the support member 31 is divided into two rectangular cavities by the separation wall 313. In other embodiments, multiple separation walls 313 may be designed as needed, and the present invention is not limited thereto.

[0058] Optionally, the width of the cavity matches the special long arm tool, so that the special long arm tool can be easily inserted into the cavity to adjust the fixing member 32, thereby adjusting the position of the telescopic connecting block 20. In addition, the setting of the cavity also provides a moving space for the displacement adjustment of the connecting rod 22.

[0059] The first wall 311 and the separation wall 313 are provided with connection holes 314 at positions corresponding to the connection rod 22 , and the connection rod 22 passes through the connection hole 314 , and the connection rod 22 is fixedly connected to the support member 31 through the cooperation between the fixing member 32 and the separation wall 313 .

[0060] In this embodiment, the fixing member 32 is two nuts disposed on both sides of the separation wall 313. The end of the connecting rod 22 away from the slider end 21 extends into the connection hole 314, and the two nuts are respectively sleeved on the connecting rod 22 and located on both sides of the separation wall 313. When the position of the telescopic connection block 20 needs to be adjusted, the nuts can be loosened to adjust the position of the telescopic connection block 20. When the position of the telescopic connection block 20 is adjusted, the nuts are tightened to fix the position of the connecting rod 22 and the support member 31.

[0061] Furthermore, the thickness of the separation wall 313 is greater than the thickness of the first wall 311 and the second wall 312 , so that the locking strength of the fixing member 32 can be significantly improved, thereby improving the stability of the connection between the telescopic connecting rod 22 and the cavity.

[0062] Furthermore, the first wall 311 can provide support for the connecting rod 22, thereby improving the structural stability of the telescopic connecting block 20. The second wall 312 can limit the retracted position of the telescopic connecting block 20, thereby preventing excessive contraction or disengagement.

[0063] In addition, the support member 31 embedded in the adjustment member 30 is disposed between the top plate 11 and the bottom plate 12 , which can effectively support the top plate 11 and the bottom plate 12 and improve the structural strength of the fixed plate 100 .

[0064] For further information, see Figure 4 As shown, the top plate 11 is provided with a first notch 111 at a position corresponding to the embedded adjustment member 30. The first notch 111 is provided to facilitate adjusting the position of the telescopic connection block 20 through the first notch 111.

[0065] See also Fig. 9 Combined with Figure 2 , Figure 3 and Figure 7 As shown, the fixed plate 100 further includes a stop plate adjusting member 40. The stop plate adjusting member 40 is disposed in the receiving cavity 15 and is disposed near the slider end 21. That is, the stop plate adjusting member 40 is disposed in a one-to-one correspondence with the telescopic connecting block 20. This arrangement can improve the structural stability of the telescopic connecting block 20 while reducing the weight of the fixed plate 100, reducing consumables and reducing costs.

[0066] The stop plate adjustment member 40 includes a first portion 41 and a second portion 42 in a stepped shape. The thickness of the first portion 41 is greater than the thickness of the second portion 42. A receiving groove 43 for receiving the slider end 21 is provided between the first portion 41 and the second portion 42. By providing the receiving groove 43, the slider end 21 can be easily retracted into the receiving cavity 15, which facilitates the installation of the stop plate 100. At the same time, the retracted position of the slider end 21 is limited to avoid excessive retraction or disengagement.

[0067] Further, the first part 41 is arranged above the slider end 21 and abuts against the top surface of the slider end 21. The first part 41 is provided with a fixing hole 411 for a fastener to pass through. Optionally, the fixing hole 411 is a threaded hole. A fastener (e.g., a bolt, etc.) can pass through the fixing hole 411 to fix the first part 41 and the slider end 21 to abut against each other, and the slider end 21 is limited and fixed in the thickness direction, thereby further improving the connection firmness and stability between the telescopic connection block 20 and the cavity.

[0068] Furthermore, a limiting protrusion 44 for limiting the outer plate 13 is provided on the side of the first part 41 facing the outer plate 13. The limiting protrusion 44 can clamp the outer plate 13 between the first part 41 and the slider end 21 to improve the stability of the overall structure. At the same time, since the slider end 21 is clamped between the outer plate 13 and the bottom plate 12, the connection firmness and stability of the telescopic connection block 20 and the cavity are improved.

[0069] Further, the second portion 42 is located between the slider end 21 and the embedded adjustment member 30. In addition, the second portion 42 is provided with an avoidance hole 421 at a position corresponding to the connecting rod 22. By providing the second portion 42, the top plate 11 and the bottom plate 12 can be effectively supported, thereby improving the structural strength of the fixed plate 100. By providing the avoidance hole 421 on the second portion 42, the connecting rod 22 can be supported, thereby improving the structural stability of the telescopic connecting block 20.

[0070] Further, referring to FIG. 4 , the top plate 11 is provided with a second notch 112 at a position corresponding to the stop plate adjustment member 40. The second notch 112 is provided to facilitate fixing the telescopic connecting rod 22 by fasteners after the telescopic connecting block 20 is in the installation position, thereby improving the convenience of operation.

[0071] When it is necessary to install the fixed plate 100 in the gap of the rotor, the fixing piece 32 can be loosened, and the slider end 21 can be retracted into the receiving groove 43, so that the outermost side of the slider end 21 is flush with the outer wall, or does not exceed the outer wall, so that the volume of the entire fixed plate 100 is small, and the fixed plate 100 can be conveniently installed in the gap of the rotor. After the fixed plate 100 is installed in the cavity as a whole, from the front end of the impeller of the rotor, the interval on the circumference of each impeller is the operating space, and the fixing piece 32 embedded in the adjustment block is tightened and adjusted using a special long arm tool. Since the weight of the fixed plate 100 becomes lighter, the nut selection operation is relatively easy, and the six slider ends 21 can be screwed out until the positioning protrusion 211 on the slider end 21 is clamped in the positioning groove. Then, the fixing piece 32 is tightened through the first notch 111, and the fastener is tightened through the second notch 112, so that the fixed plate 100 is firmly connected to the cavity. When the rotor rotates, the fixed plate 100 can play a role of separation. Through the provision of a plurality of telescopic connecting blocks 20, the load bearing capacity of the fixed plate 100 can be increased by 2 times, and the connection between the fixed plate 100 and the cavity can be made firm, the gaps on all sides of the circumference are uniform, and the gaps can be reduced to 50% of the original.

[0072] In summary, the present invention provides a fixed plate 100 and a fiber separator having the fixed plate 100. By setting a hollow receiving cavity 15 on the fixed plate 100, the material usage of the fixed plate 100 is reduced, thereby reducing the overall weight of the fixed plate 100, and reducing the manufacturing cost, reducing the operating burden of the fiber separator, and improving the energy efficiency of the fiber separator. By setting a plurality of telescopic connection blocks 20 in the receiving cavity 15, the telescopic connection blocks 20 can pass through the avoidance opening 131 on the outer plate 13 and abut against the cavity of the fiber separator, so that the connection between the fixed plate 100 and the cavity of the fiber separator is more stable. In addition, the setting of the telescopic connection block 20 allows the telescopic connection block 20 to be retracted into the receiving cavity 15 when the fixed plate 100 is installed, flush with the outer wall, so that the fixed plate 100 can be conveniently installed in the gap of the rotor. In addition, the setting of the telescopic connection block 20 can allow fine-tuning to a certain extent to facilitate adaptation to different cavities, thereby improving the adaptability and reliability of the fixed plate 100. In addition, the telescopic connection block 20 can pass through the special avoidance opening 131 on the outer plate 13 to abut against the cavity. This design helps to improve the sealing between the fixed plate 100 and the cavity. Good sealing performance can prevent the leakage of fibers and impurities, ensuring the efficiency and quality of the separation process. By reducing the weight of the fixed plate 100 and improving the connection method between the fixed plate 100 and the cavity, it helps to improve the dynamic balance of the fiber separator, reduce vibration and noise during operation, improve the stability and safety of the equipment operation, reduce maintenance costs and replacement frequency, and extend the service life of the fiber separator.

[0073] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
