Description

Technical Field

[0001] This invention relates to the field of fiber separator technology, and more particularly to a plate setter and a fiber separator. Background Technology

[0002] A fiber separator is a papermaking wood chip fiber processing device that utilizes the density difference between wood chip fibers and impurities to remove light and heavy impurities from the wood chip fiber raw material. It also has the functions of loosening and screening. The fiber separator uses high-speed centrifugal force to cause heavy impurities, fibers, and light impurities to separate into strata due to their different densities. These strata are then separated by the hydraulic pressure generated by the impeller's rotation.

[0003] The stator plate is a crucial component of the fiber separator. Working in conjunction with the rotor, it plays a vital role in the separator's separation efficiency and stability. Existing stators suffer from design flaws, resulting in large gaps between the stator plate and the cavity, leading to poor sealing and impacting separation performance. Furthermore, the stator plate's excessive weight and unstable fixing method within the cavity make it prone to displacement during operation, potentially causing it to contact the rotor, disrupting dynamic balance, and resulting in abnormal machine vibration, whistling, and metallic friction noises. Ultimately, this can lead to emergency shutdowns and shorten the fiber separator's lifespan. Summary of the Invention

[0004] To solve the above-mentioned technical problems, the present invention provides a mounting plate that is lightweight, securely positioned, easy to install, and has good sealing performance.

[0005] The technical solution of this invention is:

[0006] A plate, used in a fiber separator, comprising:

[0007] The outer casing includes a top plate and a bottom plate disposed opposite each other, and an outer side plate surrounding the top plate and the bottom plate, wherein a receiving cavity is formed between the top plate, the bottom plate and the outer side plate.

[0008] Several telescopic connecting blocks are disposed within the receiving cavity;

[0009] The outer side plate has a clearance opening corresponding to the position of the telescopic connecting block. The telescopic connecting block is configured to pass through the clearance opening at least partially to abut against the cavity of the fiber separator.

[0010] Furthermore, it also includes an embedded adjustment member disposed within the receiving cavity. The telescopic connecting block includes a slider end that is at least partially exposed outside the clearance opening and a connecting rod connected to the slider end. The connecting rod is at least partially inserted into the embedded adjustment member, and the position of the telescopic connecting block is adjusted by the embedded adjustment member.

[0011] Furthermore, the embedded adjustment member includes a support member and at least one fixing member. The support member includes a first wall facing the slider end, a second wall away from the slider end, and at least one separating wall disposed between the first wall and the second wall. The first wall and the separating wall are provided with connecting holes corresponding to the position of the connecting rod. The connecting rod passes through the connecting holes and is fixedly connected to the support member by the fixing member.

[0012] Furthermore, a positioning protrusion is provided on the side of the slider end opposite to the connecting rod.

[0013] Furthermore, it also includes a stop plate adjustment member disposed within the receiving cavity and near the end of the slider. The stop plate adjustment member includes a first part and a second part in a stepped shape, and a receiving groove for accommodating the end of the slider is provided between the first part and the second part.

[0014] Furthermore, the first part is disposed above the slider end and abuts against the slider end, the first part is provided with a fixing hole for fasteners to pass through, the second part is located between the slider end and the embedded adjustment member, and the second part is provided with a clearance hole corresponding to the position of the connecting rod.

[0015] Furthermore, the top plate is provided with a first notch and a second notch respectively corresponding to the positions of the embedded adjustment member and the stop plate adjustment member.

[0016] Furthermore, the top plate is provided with a first locking member, and the bottom plate is provided with a corresponding second locking member. The top plate and the bottom plate are detachably connected by the first locking member and the second locking member.

[0017] Furthermore, the extension lines of several telescopic connecting blocks converge at a central point, and the several telescopic connecting blocks radiate uniformly with the central point as the center.

[0018] The present invention also provides a fiber separator having the aforementioned fixed plate, the fiber separator comprising a cavity and a rotor disposed within the cavity and the aforementioned fixed plate.

[0019] The beneficial technical effects of this invention are:

[0020] This invention provides a fixed plate and a fiber separator having the fixed plate. By setting a hollow receiving cavity in the fixed plate, the amount of material used in the fixed plate is reduced, thereby reducing the overall weight of the fixed plate, manufacturing costs, and the operating burden of the fiber separator, and improving the energy efficiency of the fiber separator. By setting several telescopic connecting blocks in the receiving cavity, the telescopic connecting blocks can pass through the clearance openings on the outer side plate and abut against the cavity of the fiber separator, thereby making the connection between the fixed plate and the cavity of the fiber separator more stable. In addition, the setting of the telescopic connecting blocks allows the telescopic connecting blocks to be retracted into the receiving cavity and flush with the outer side wall during the installation of the fixed plate, thereby facilitating the installation of the fixed plate in the gap of the rotor. Furthermore, the setting of the telescopic connecting blocks allows for a certain degree of fine adjustment to accommodate different cavities, improving the adaptability and reliability of the fixed plate. In addition, the telescopic connecting blocks can pass through the specially designed clearance openings on the outer side plate and abut against the cavity, a design that helps to improve the sealing between the fixed plate 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 stationary plate and improving the connection between the stationary plate and the cavity, the dynamic balance of the fiber separator can be improved, vibration and noise during operation can be reduced, the stability and safety of equipment operation can be improved, maintenance costs and replacement frequency can be reduced, and the service life of the fiber separator can be extended.

Detailed Implementation

[0032] In order to better understand the technical means of the present invention and to implement it in accordance with the contents of the specification, the specific embodiments of the present invention will be further described in detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0033] This invention provides a fiber separator (not shown). The fiber separator includes a pulp inlet, a pulp outlet, and a cavity disposed between the pulp inlet and the pulp outlet. A rotor and a stationary plate 100 are disposed within the cavity. The rotor rotates at high speed to separate and screen the fiber pulp. The stationary plate 100 is disposed in the middle of the rotor to divide the cavity into an intake cavity and a separation cavity. Furthermore, the stationary plate 100 provides necessary structural support and a working interface for the rotor, ensuring that the rotor maintains the correct position and dynamic balance during high-speed rotation.

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

[0035] The outer casing 10 includes a top plate 11 and a bottom plate 12 disposed opposite to each other, and an outer side plate 13 and an inner side plate 14 surrounding the top plate 11 and the bottom plate 12. A hollow receiving cavity 15 is formed between the top plate 11, the bottom plate 12, the outer side plate 13, and the inner side plate 14. A plurality of telescopic connecting blocks 20 are provided within the receiving cavity 15. The outer side plate 13 has clearance openings 131 corresponding to the positions of the telescopic connecting blocks 20. The telescopic connecting blocks 20 are configured to at least partially pass through the clearance openings 131 to abut against the cavity of the fiber separator. By providing the hollow receiving cavity 15, the amount of material used in the fixed plate 100 is reduced, thereby reducing the overall weight of the fixed plate 100, lowering manufacturing costs, reducing the operating burden of the fiber separator, and improving the energy efficiency of the fiber separator.

[0036] By providing several telescopic connecting blocks 20 within the receiving cavity 15, the telescopic connecting blocks 20 can pass through the clearance openings 131 on the outer side plate 13 and 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. Furthermore, the telescopic connecting blocks 20 allow the fixed plate 100 to be retracted into the receiving cavity 15 and flush with the outer side wall during installation, facilitating installation of the fixed plate 100 in the gaps of the rotor. Moreover, the telescopic connecting blocks 20 allow for a certain degree of fine-tuning to accommodate different cavities, improving the adaptability and reliability of the fixed plate 100. Additionally, the telescopic connecting blocks 20 can pass through the specially provided clearance openings 131 on the outer side plate 13 and abut against the cavity; this design helps improve the sealing performance between the fixed plate 100 and the cavity. Good sealing performance prevents 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 between the fixed plate 100 and the cavity, the dynamic balance of the fiber separator can be improved, vibration and noise during operation can be reduced, the stability and safety of equipment operation can be improved, maintenance costs and replacement frequency can be reduced, and the service life of the fiber separator can be extended.

[0037] Please continue reading. Figures 1 to 6 As shown, both the top plate 11 and the bottom plate 12 are annular thin plates with a thickness of approximately 8 to 15 millimeters.

[0038] Optionally, in this embodiment, the top plate 11 consists of two semi-circular thin plates, which are fixedly connected by a first locking member 16. That is, by welding the first locking member 16 to the two semi-circular thin plates, the fixed plate 100 becomes a complete circular thin plate. Similarly, the bottom plate 12 also consists of two semi-circular thin plates, which are connected by a second locking member 17 to form a complete circular thin plate. Of course, in other embodiments, the top plate 11 and the bottom plate 12 may be designed as complete circular thin plates themselves, or as multiple segments, which are connected and fixed by a connecting structure or by 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 is a hollow cylindrical cavity with a thickness of approximately 100 mm and a diameter of approximately 1000 mm. This design improves the original fixed plate 100 from a machined thick plate to a welded sheet metal assembly, significantly reducing its weight. Optionally, the weight of the fixed plate 100 can be reduced to one-third of its original weight, thereby reducing the amount of material used and the overall weight of the fixed plate 100. This also reduces manufacturing costs, decreases the operating burden on the fiber separator, and improves the energy efficiency of the fiber separator. Furthermore, the reduced weight facilitates its installation at the rotor center, improving installation convenience.

[0040] Please continue reading. Figure 5 and Figure 6 and combined Figures 1 to 4 As shown, the top plate 11 is provided with a first locking member 16, and the bottom plate 12 is provided with a corresponding second locking member 17. The top plate 11 and the bottom plate 12 are detachably connected by the first locking member 16 and the second locking member 17. This arrangement allows the fixed plate 100 structure to be easily disassembled for maintenance and replacement (e.g., replacing the internal telescopic connecting block 20 or other structures, or replacing the top plate 11 and the bottom plate 12), thereby reducing maintenance costs.

[0041] Furthermore, the top plate 11 is provided with at least one first locking member 16. In this embodiment, there are two first locking members 16, which are respectively welded to the top plate 11. The two first locking members 16 are arranged symmetrically about the center of the top plate 11. This arrangement provides better balance and stability. Furthermore, the two first locking members 16 enable a more stable connection between the top plate 11 and the bottom plate 12, and also make the connection between the top plate 11 and the bottom plate 12 more secure. Of course, in other embodiments, one or more first locking members 16 may be provided, and the present invention is not limited to this.

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

[0043] Furthermore, 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 corresponding countersunk hole or threaded hole. Fasteners, such as screws, 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 stepped portions, and the two stepped 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 provided with a corresponding 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 during installation and to achieve rapid 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 post. In other embodiments, the first positioning member 161 and the second positioning member 171 may also have other structures.

[0047] Please see Figure 7 and combined Figure 2 and Figure 3 As shown, several telescopic connecting blocks 20 are disposed in the receiving cavity 15 of the outer shell 10. The telescopic connecting blocks 20 can pass through the clearance opening 131 on the outer side 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. Furthermore, each part of the outer side 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 several telescopic connecting blocks 20 converge at a central point, and the telescopic connecting blocks 20 are arranged in a uniform radial pattern with the central point as the center. This arrangement ensures that the telescopic connecting blocks 20 are evenly distributed within the receiving cavity 15 of the outer shell 10, thereby balancing stress, reducing local stress concentration, 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, the housing 10 has six telescopic connecting blocks 20 within its receiving cavity 15. The six telescopic connecting blocks 20 are evenly distributed within the receiving cavity 15 around the center of the housing 10. In other embodiments, other numbers of telescopic connecting blocks 20 may be designed as needed.

[0050] The telescopic connecting block 20 includes a slider end 21 and a connecting rod 22 connected to the slider end 21. The slider end 21 is at least partially exposed outside the clearance opening 131 on the outer side wall to abut against the cavity of the fiber separator. The telescopic connecting block 20 facilitates the installation of the fixed plate 100 inside the rotor and the fixing of the fixed plate 100 within the cavity, improving the stability and balance of the connection between the fixed plate 100 and the cavity. Furthermore, since the slider end 21 remains at least partially within the clearance opening 131, it provides a good seal, effectively isolating the suction cavity and the separation cavity.

[0051] Furthermore, a positioning protrusion 211 is provided on the side of the slider end 21 facing away from the connecting rod 22. A positioning groove is provided in the cavity of the fiber separator corresponding to the position of the positioning protrusion 211. The positioning protrusion 211 and the positioning groove enable the fixed plate 100 to be quickly installed in the cavity, achieving 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 outer shell 10, thereby improving the sealing performance between the telescopic connecting block 20 and the cavity.

[0053] Furthermore, in this embodiment, the connecting rod 22 is a threaded screw. The threaded connecting rod 22 is movably connected to the embedded adjusting member 30, thereby facilitating the adjustment of the position of the slider end 21, allowing the slider end 21 to be telescopically connected to the clearance opening 131. Of course, in other embodiments, the telescopic connecting block 20 can also be movably connected to the clearance opening 131 of the housing 10 in other ways. For example, it can be achieved through a sleeve and telescopic rod, or by setting a locking structure, etc. This invention is not limited to these methods.

[0054] Please see Figure 8 And in conjunction with the diagram Figure 2 , Figure 3 and Figure 7 As shown, the fixed plate 100 also includes an embedded adjustment member 30 disposed within the receiving cavity 15. The number of embedded adjustment members 30 corresponds one-to-one with the telescopic connecting block 20. The position of the telescopic connecting block 20 can be effectively adjusted by means of 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 provides support for the connecting rod 22, and the tightness of the fixing member 32 is used to adjust the position of the slider end 21 and fix it to the installation position.

[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 separating wall 313 disposed between the first wall 311 and the second wall 312. That is, the support member 31 is a partition-type cuboid structure.

[0057] In this embodiment, a separation wall 313 is provided, which divides the support member 31 into two cuboid cavities. 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 is matched to a dedicated long-arm tool, facilitating the insertion of the tool into the cavity to adjust the fixing member 32, thereby adjusting the position of the telescopic connecting block 20. Additionally, the cavity provides space for the displacement adjustment of the connecting rod 22.

[0059] The first wall 311 and the separating wall 313 are provided with connecting holes 314 corresponding to the position of the connecting rod 22. The connecting rod 22 passes through the connecting hole 314 and is fixedly connected to the support member 31 through the cooperation of the fixing member 32 and the separating wall 313.

[0060] In this embodiment, the fixing member 32 consists of two nuts disposed on both sides of the separating wall 313. The end of the connecting rod 22 furthest from the slider end 21 extends into the connecting hole 314, and the two nuts are respectively fitted onto the connecting rod 22, located on both sides of the separating wall 313. When it is necessary to adjust the position of the telescopic connecting block 20, the nuts can be loosened to adjust the position of the telescopic connecting block 20. After the position of the telescopic connecting 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 that of the first wall 311 and the second wall 312, which can significantly improve the locking strength of the fastener 32, thereby improving the stability of the connection between the telescopic connecting rod 22 and the cavity.

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

[0063] In addition, the support member 31 of the embedded 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] Further, please refer to Figure 4 As shown, the top plate 11 has a first notch 111 corresponding to the position of the embedded adjustment member 30. The first notch 111 is provided to facilitate the adjustment of the position of the telescopic connecting block 20.

[0065] Please see Figure 9 and combined Figure 2 , Figure 3 and Figure 7 As shown, the fixed plate 100 also includes a stop-fixed plate adjustment member 40. The stop-fixed plate adjustment member 40 is disposed within the receiving cavity 15 and is located near the slider end 21. That is, the stop-fixed plate adjustment member 40 is disposed in a one-to-one correspondence with the telescopic connecting block 20. This arrangement improves the structural stability of the telescopic connecting block 20 while reducing the weight of the fixed plate 100, reducing material consumption, and lowering costs.

[0066] The stop plate adjustment member 40 includes a stepped first part 41 and a second part 42. The thickness of the first part 41 is greater than the thickness of the second part 42. A receiving groove 43 is provided between the first part 41 and the second part 42 to accommodate the slider end 21. By providing the receiving groove 43, the slider end 21 can be easily retracted into the receiving cavity 15, facilitating the installation of the stop plate 100. Simultaneously, the retraction position of the slider end 21 is limited, preventing excessive retraction or dislodgement.

[0067] Furthermore, the first portion 41 is disposed above the slider end 21 and abuts against the top surface of the slider end 21. The first portion 41 is provided with a fixing hole 411 for a fastener to pass through. Optionally, the fixing hole 411 is a threaded hole. Fasteners (e.g., bolts) can pass through the fixing hole 411 to fix the first portion 41 to the slider end 21, thereby limiting and fixing the slider end 21 in the thickness direction, further improving the connection strength and stability between the telescopic connecting block 20 and the cavity.

[0068] Furthermore, the first portion 41 has a limiting protrusion 44 on its side facing the outer side plate 13 for limiting the outer side plate 13. The limiting protrusion 44 clamps the outer side plate 13 between the first portion 41 and the slider end 21, improving the stability of the overall structure. Simultaneously, since the slider end 21 is clamped between the outer side plate 13 and the bottom plate 12, the connection strength and stability between the telescopic connecting block 20 and the cavity are improved.

[0069] Furthermore, the second part 42 is located between the slider end 21 and the embedded adjustment member 30. Also, the second part 42 has a clearance hole 421 corresponding to the position of the connecting rod 22. By providing the second part 42, the top plate 11 and the bottom plate 12 can be effectively supported, improving the structural strength of the fixed plate 100. By providing the clearance hole 421 on the second part 42 to support the connecting rod 22, the structural stability of the telescopic connecting block 20 is improved.

[0070] Further, as shown in Figure 4, the top plate 11 has a second notch 112 corresponding to the position of the stop plate adjustment member 40. By providing the second notch 112, it is convenient to fix the telescopic connecting rod 22 with fasteners after the telescopic connecting block 20 is in the installation position, thereby improving the ease of operation.

[0071] When the fixed plate 100 needs to be installed in the gap of the rotor, the fixing member 32 can be loosened, and the slider end 21 can be retracted into the receiving groove 43, so that the outermost part of the slider end 21 is flush with the outer wall, or does not extend beyond the outer wall, thereby making the overall volume of the fixed plate 100 smaller, which can facilitate the installation of the fixed plate 100 in the gap of the rotor. After the fixed plate 100 is installed into the cavity, the working space is the interval on the circumference of each impeller from the front end of the rotor impeller. Using a special long-arm tool, the fixing member 32 embedded in the adjustment block is tightened and adjusted. Since the fixed plate 100 is lighter, the nut operation is relatively easy. All 6 slider ends 21 can be unscrewed until the positioning protrusion 211 on the slider end 21 is engaged in the positioning groove. Then, the fixing member 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 stationary plate 100 can serve as a separator. By setting several telescopic connecting blocks 20, the load-bearing capacity of the stationary plate 100 can be increased by 2 times, and the connection between the stationary plate 100 and the cavity can be made firm, the gaps around the circumference can be uniform, and the gaps can be reduced to 50% of the original size.

[0072] In summary, the present invention provides a fixed plate 100 and a fiber separator having the fixed plate 100. By providing a hollow receiving cavity 15 on the fixed plate 100, the amount of material used in the fixed plate 100 is reduced, thereby reducing the overall weight of the fixed plate 100, lowering manufacturing costs, reducing the operating burden of the fiber separator, and improving the energy efficiency of the fiber separator. By providing a plurality of telescopic connecting blocks 20 in the receiving cavity 15, the telescopic connecting blocks 20 can pass through the clearance openings 131 on the outer side plate 13 and 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 provision of telescopic connecting blocks 20 allows the telescopic connecting blocks 20 to be retracted into the receiving cavity 15 and flush with the outer side wall during installation, thereby facilitating the installation of the fixed plate 100 in the gap of the rotor. Furthermore, the provision of telescopic connecting blocks 20 allows for a certain degree of fine adjustment to accommodate different cavities, improving the adaptability and reliability of the fixed plate 100. Furthermore, the telescopic connecting block 20 can pass through the specially designed clearance opening 131 on the outer side plate 13 and abut against the cavity. This design helps improve the sealing performance between the fixed plate 100 and the cavity. Good sealing performance can prevent 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, the dynamic balance of the fiber separator is improved, vibration and noise during operation are reduced, the stability and safety of equipment operation are improved, maintenance costs and replacement frequency are reduced, and the service life of the fiber separator is extended.

[0073] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
