Description

Technical Field

[0001] The present invention relates to a grinding and mixing device, in particular to a raw material grinding and mixing device for ceramic product processing, which is applied in the field of ceramic product processing. Background Art

[0002] When processing ceramic products, multiple raw materials need to be ground and mixed to a certain extent so that the multiple raw materials can be ground into the required size, and then the multiple ground raw materials are mixed and stirred.

[0003] When a conventional raw material grinding and mixing device for ceramic product processing is used, the raw materials are ground by the combination of a grinding box and a grinding plate. However, the combination of the grinding box and the grinding plate results in a short grinding time for the raw materials, and the raw materials cannot be fully and evenly ground. That is, the grinding effect of the raw materials by the device is poor, making it inconvenient to carry out subsequent processing steps.

[0004] To solve the above problems, the specification of Chinese patent CN220879043U discloses a raw material grinding and mixing device for ceramic product processing, which relates to ceramic raw material processing, including a processing seat, a grinding assembly and a shock assembly, wherein: a semicircular grinding groove is opened on the top of the processing seat; the grinding assembly includes a fixed cylinder, a movable rod and a grinding roller, a bearing bracket is arranged on the processing seat, and a horizontally arranged moving rod is movably arranged on the bearing bracket. The raw material grinding and mixing device for ceramic product processing is provided with the grinding assembly. In the process that the moving rod drives the fixed cylinder and the movable rod to rotate back and forth, the grinding groove can grind a variety of raw materials inside the semicircular grinding groove, and the grinding time can be determined according to the reciprocating time of the moving rod; at the same time, by adjusting the elastic action of the spring, the pressing force of the grinding roller on the inner side wall of the semicircular grinding groove can be larger, and in the subsequent rotation process of the grinding roller, a better grinding effect can be produced on the raw material.

[0005] In the above-mentioned prior art, the raw materials are only crushed back and forth by the grinding roller, and the single grinding effect is poor. Multiple reciprocating motions are required to achieve the ideal grinding effect. Therefore, the grinding efficiency within a certain unit time is relatively low. Although the grinding can be accelerated by changing the reciprocating speed, when the speed is too fast, the wear of the grinding roller will inevitably increase, which will reduce the service life of the equipment and cannot give a good balance between processing efficiency and the service life of the device. Summary of the invention

[0006] In view of the above-mentioned prior art, the technical problem to be solved by the present invention is how to design a raw material grinding and mixing device for ceramic product processing which can achieve high grinding efficiency under the premise of ensuring low equipment loss.

[0007] In order to solve the above problems, the present invention provides a raw material grinding and mixing device for ceramic product processing, comprising a processing box and a vibrating mechanism, wherein two vibrating mechanisms are provided and are respectively located on both sides of the processing box, a driving rod is fixed between the two vibrating mechanisms, a swing rod is installed in the middle of the driving rod, and a grinding roller located in the processing box is installed at the lower end of the swing rod, and the grinding roller is used to grind the raw materials for ceramic product processing;

[0008] An upper arc partition and a lower arc partition are fixed in the processing box, and a feed hole is opened in the middle of the upper arc partition, and discharge holes are opened at both ends of the lower arc partition. The feed hole and the discharge hole are both rotatably connected with a baffle plate that can be automatically reset, and a trigger opening and closing structure is installed on the baffle plate;

[0009] The grinding roller includes a grinding shell and a grinding core. There is a gap between the inner peripheral wall of the grinding shell and the peripheral side wall of the grinding core. Both the inner peripheral wall of the grinding shell and the peripheral side wall of the grinding core are provided with protrusions for grinding. A connecting shaft is fixed in the middle of the grinding core. The end of the connecting shaft movably passes through the side walls at the front and rear ends of the processing box and is fixed to the lower end of the swing rod. The grinding shell is rotatably sleeved on the connecting shaft of the grinding core through a bearing.

[0010] An opening for feeding is provided at one end of the grinding shell, and a movable sealing group is installed on the opening of the grinding shell. The movable sealing group is adapted to the trigger opening and closing structure. The upper and lower ends of the grinding shell respectively roll and fit with the bottom surface of the upper arc-shaped partition and the upper surface of the lower arc-shaped partition. When the grinding shell rolls to the bottom of the feed hole and the top of the discharge hole, the movable sealing group is opened by the trigger opening and closing structure on the material blocking plate.

[0011] In the raw material grinding and mixing device for ceramic product processing, an external reciprocating linear driving mechanism is used to synchronously drive the driving rod and the vibrating mechanism, so that the vibrating mechanism hits both sides of the processing box during linear reciprocating movement, causing the processing box to vibrate to a certain extent, which is beneficial to the aggregation of the raw materials in the processing box and facilitates grinding;

[0012] At the same time, the driving rod drives the swing rod to swing, so that the grinding roller at the lower end of the swing rod swings accordingly. During the reciprocating swing of the grinding roller, the grinding shell and the grinding core rotate relative to each other, that is, the grinding shell rotates due to friction with the upper surface of the lower arc-shaped partition, while the grinding core does not rotate.

[0013] When the grinding roller moves to the position directly below the feed hole, the opening on the grinding shell corresponds to the position of the feed hole. At this time, the trigger opening and closing structure is triggered, so that the movable sealing group and the baffle plate in the feed hole are opened at the same time, so that the ceramic raw material to be ground above the upper arc-shaped partition falls into the gap between the grinding shell and the grinding core. When the grinding roller continues to move, it disengages from the trigger opening and closing structure, so that the movable sealing group and the baffle plate in the feed hole are closed at the same time, so that the ceramic raw material to be ground remains in the grinding roller. Furthermore, the ceramic raw material is ground when the grinding shell and the grinding core rotate relative to each other. Since there is a protrusion for grinding between the two, the grinding roller has a better grinding effect on the ceramic raw material, and during the rotation of the grinding shell, multiple grindings of the ceramic raw material have been completed, and the grinding efficiency is also higher.

[0014] Afterwards, when the grinding roller moves to above the discharge hole, the opening on the grinding shell corresponds to the position of the discharge hole. At this time, the trigger opening and closing structure at the discharge hole is triggered, so that the discharge hole and the opening on the grinding shell are opened at the same time, so that the ground ceramic raw material in the grinding roller is discharged from the discharge hole, completing the grinding operation of the ceramic raw material. After that, the grinding roller moves in the direction and performs the next feeding, grinding and discharging.

[0015] Such reciprocating movement can complete two complete grinding operations in one reciprocating stroke between one end of the processing box and the other end of the processing box, so as to achieve the effect of using a shorter stroke and less time to complete the grinding operation. At the same time, it improves the uniformity of the ceramic raw materials after grinding, which is more conducive to the subsequent processing of the ceramic raw materials, and realizes the effect of achieving higher grinding efficiency while ensuring less equipment loss.

[0016] As a further supplement to the present application, the trigger opening and closing structure includes a movable ball, the movable ball of the baffle plate installed on the upper arc-shaped partition is located below the baffle plate, and the movable ball of the baffle plate installed on the lower arc-shaped partition is located above the baffle plate, and the movable ball is movably connected to the baffle plate through a movable limiting connection structure;

[0017] During the rolling process, the grinding shell makes the opening on the grinding shell correspond to the position of the baffle plate on the upper arc partition and the baffle plate on the lower arc partition. At this time, the movable ball pushes open the movable sealing group and the baffle plate respectively, so that the opening on the grinding shell is connected with the feed hole or the discharge hole.

[0018] As a further supplement to the present application, the limiting connection structure includes a connecting rod and a limiting plate, the connecting rod is fixed on the movable ball, the connecting rod movably passes through the middle of the baffle plate, the limiting plate is fixed to one end of the connecting rod away from the movable ball, and the diameter of the limiting plate is greater than the diameter of the connecting rod;

[0019] A notch is arranged in the middle of the baffle plate, and when the baffle plate is closed, the connecting rod moves through the notch.

[0020] As a further supplement to the present application, the limiting connection structure also includes a first spring and a fixed plate. The first spring is fixed to the side of the limiting plate at the discharge hole away from the movable ball. The fixed plate is fixed to the inner side walls at the front and rear ends of the processing box, and one side of the fixed plate is fixed to the end of the first spring away from the limiting plate.

[0021] As a further supplement to the present application, the movable sealing group includes a fixed ring, a movable block and a slide rail. The fixed ring is fixed in the opening of the grinding shell. The slide rail is fixed to the inner wall of the fixed ring. The slide rail is arranged parallel to the radial direction of the grinding shell. The movable block is slidably connected to the fixed ring through the slide rail. When the movable block contacts the movable ball, the movable block is separated from the fixed ring and a gap is exposed, and there is a gap between the movable block and the protrusion on the grinding core.

[0022] As a further supplement to the present application, a slide groove is provided on one side of the slide rail close to the movable block, and ear blocks slidably connected to the slide groove are integrally formed on both sides of the movable block;

[0023] A second spring is fixed on one side of the ear block close to the grinding core, and the other end of the second spring is fixed to the inner wall of one end of the slide groove close to the grinding core.

[0024] As a further supplement to the present application, an elastic sealing piece is fixed to the inner wall of one end of the slide away from the grinding core, and the other end of the elastic sealing piece is fixed to the side of the ear block away from the second spring. When the elastic sealing piece is extended and deformed, it always seals the opening between the slide groove and one side of the ear block.

[0025] As a further supplement to the present application, both sides of the processing box are provided with vibration grooves that cooperate with the vibration mechanism;

[0026] The lower end of the processing box is fixed and connected with a discharge pipe, and the middle part of the lower arc-shaped partition is fixed and connected with a recovery pipe. The recovery pipe is located directly below the feed hole. The inner diameter of the upper end of the recovery pipe is larger than the maximum length of the feed hole, and the lower end of the recovery pipe is fixed and passes through the bottom wall of the processing box.

[0027] As another improvement of the present application, the outer peripheral side wall of the grinding shell is integrally formed with tooth blocks distributed along the circumference of the central axis of the grinding shell, and the upper surface of the lower arc-shaped partition is also integrally formed with a plurality of tooth blocks evenly distributed and meshing with the tooth blocks on the grinding shell.

[0028] In summary, the driving rod and the vibrating mechanism are synchronously driven by an external reciprocating linear driving mechanism, so that the vibrating mechanism hits both sides of the processing box in a linear reciprocating motion, causing the processing box to vibrate to a certain extent, which is beneficial to the aggregation of the raw materials in the processing box and facilitates grinding;

[0029] At the same time, the driving rod drives the swing rod to swing, so that the grinding roller at the lower end of the swing rod swings accordingly. During the reciprocating swing of the grinding roller, the grinding shell and the grinding core rotate relative to each other, that is, the grinding shell rotates due to friction with the upper surface of the lower arc-shaped partition, while the grinding core does not rotate.

[0030] When the grinding roller moves to the position directly below the feed hole, the opening on the grinding shell corresponds to the position of the feed hole. At this time, the trigger opening and closing structure is triggered, so that the movable sealing group and the baffle plate in the feed hole are opened at the same time, so that the ceramic raw material to be ground above the upper arc-shaped partition falls into the gap between the grinding shell and the grinding core. When the grinding roller continues to move, it disengages from the trigger opening and closing structure, so that the movable sealing group and the baffle plate in the feed hole are closed at the same time, so that the ceramic raw material to be ground remains in the grinding roller. Furthermore, the ceramic raw material is ground when the grinding shell and the grinding core rotate relative to each other. Since there is a protrusion for grinding between the two, the grinding roller has a better grinding effect on the ceramic raw material, and during the rotation of the grinding shell, multiple grindings of the ceramic raw material have been completed, and the grinding efficiency is also higher.

[0031] Afterwards, when the grinding roller moves to above the discharge hole, the opening on the grinding shell corresponds to the position of the discharge hole. At this time, the trigger opening and closing structure at the discharge hole is triggered, so that the discharge hole and the opening on the grinding shell are opened at the same time, so that the ground ceramic raw material in the grinding roller is discharged from the discharge hole, completing the grinding operation of the ceramic raw material. After that, the grinding roller moves in the direction and performs the next feeding, grinding and discharging.

[0032] Such reciprocating movement can complete two complete grinding operations in one reciprocating stroke between one end of the processing box and the other end of the processing box, so as to achieve the effect of using a shorter stroke and less time to complete the grinding operation. At the same time, it improves the uniformity of the ceramic raw materials after grinding, which is more conducive to the subsequent processing of the ceramic raw materials, and realizes the effect of achieving higher grinding efficiency while ensuring less equipment loss.

DETAILED DESCRIPTION

[0044] The first implementation method:

[0046] An upper arc partition 11 and a lower arc partition 12 are fixedly arranged in the processing box 1, and a feed hole 111 is opened in the middle of the upper arc partition 11, and discharge holes 121 are opened at both ends of the lower arc partition 12. The feed hole 111 and the discharge hole 121 are both rotatably connected with a baffle plate 7 that can be automatically reset, and a trigger opening and closing structure is installed on the baffle plate 7;

[0047] A disturbance structure is also provided above the upper arc-shaped partition 11, and the disturbance structure also swings with the swing of the swing rod 4, so as to pre-mix the ceramic raw materials above the upper arc-shaped partition 11, so as to facilitate the subsequent mixing and grinding of the ceramic raw materials;

[0048] The grinding roller 5 includes a grinding shell 51 and a grinding core 52. There is a gap between the inner peripheral wall of the grinding shell 51 and the peripheral side wall of the grinding core 52. Both the inner peripheral wall of the grinding shell 51 and the peripheral side wall of the grinding core 52 are provided with protrusions for grinding. A connecting shaft is fixed in the middle of the grinding core 52. The end of the connecting shaft movably passes through the side walls at the front and rear ends of the processing box 1 and is fixed to the lower end of the swing rod 4. The grinding shell 51 is rotatably sleeved on the connecting shaft of the grinding core 52 through a bearing 53.

[0049] The front and rear ends of the processing box 1 are also provided with arc-shaped through holes to facilitate the extension of the connecting shaft, thereby meeting the connection requirements of the connecting shaft and the swing rod 4;

[0050] An opening for feeding is provided at one end of the grinding shell 51, and a movable sealing group 8 is installed on the opening of the grinding shell 51. The movable sealing group 8 is adapted to the trigger opening and closing structure. The upper and lower ends of the grinding shell 51 roll and fit with the bottom surface of the upper arc-shaped partition 11 and the upper surface of the lower arc-shaped partition 12 respectively. When the grinding shell 51 rolls to the bottom of the feed hole 111 and the top of the discharge hole 121, the movable sealing group 8 is opened by the trigger opening and closing structure on the baffle plate 7.

[0051] Based on the above structure, an external reciprocating linear driving mechanism (such as a hydraulic cylinder, a pneumatic cylinder) is used to synchronously drive the driving rod 3 and the vibrating mechanism 2, so that the vibrating mechanism 2 hits both sides of the processing box 1 during the linear reciprocating movement, so that the processing box 1 generates a certain vibration, which is beneficial to the aggregation of the raw materials in the processing box 1 and is convenient for grinding;

[0052] At the same time, the driving rod 3 drives the swing rod 4 to swing, so that the grinding roller 5 at the lower end of the swing rod 4 swings accordingly. During the reciprocating swinging process of the grinding roller 5, the grinding shell 51 and the grinding core 52 rotate relative to each other, that is, the grinding shell 51 rotates due to friction with the upper surface of the lower arc-shaped partition 12, while the grinding core 52 does not rotate.

[0053] When the grinding roller 5 moves to the position directly below the feed hole 111, the opening on the grinding shell 51 corresponds to the position of the feed hole 111. At this time, the trigger opening and closing structure is triggered, so that the movable sealing group 8 and the baffle plate 7 in the feed hole 111 are opened at the same time, so that the ceramic raw material to be ground above the upper arc-shaped partition 11 falls into the gap between the grinding shell 51 and the grinding core 52. When the grinding roller 5 continues to move, it disengages from the trigger opening and closing structure, so that the movable sealing group 8 and the baffle plate 7 in the feed hole 111 are closed at the same time, so that the ceramic raw material to be ground remains in the grinding roller 5. Furthermore, when the grinding shell 51 and the grinding core 52 rotate relative to each other, the ceramic raw material is ground. Since there is a protrusion for grinding between the two, the grinding roller 5 has a better grinding effect on the ceramic raw material, and during the rotation of the grinding shell 51, multiple grindings of the ceramic raw material have been completed, and the grinding efficiency is also higher.

[0054] Afterwards, when the grinding roller 5 moves to above the discharge hole 121, the opening on the grinding shell 51 corresponds to the position of the discharge hole 121. At this time, the trigger opening and closing structure at the discharge hole 121 is triggered, so that the discharge hole 121 and the opening on the grinding shell 51 are opened at the same time, so that the ground ceramic raw material in the grinding roller 5 is discharged from the discharge hole 121, and the grinding operation of the ceramic raw material is completed. After that, the grinding roller 5 generates a reverse movement and performs the next feeding, grinding and discharging.

[0055] Such reciprocating movement can complete two complete grinding operations in one reciprocating stroke between one end of the processing box 1 and the other end of the processing box 1, so as to achieve the effect of using a shorter stroke and less time to complete the grinding operation, and at the same time improve the uniformity of the ceramic raw materials after grinding, which is more conducive to the subsequent processing of the ceramic raw materials, and realizes the effect of achieving higher grinding efficiency while ensuring less equipment loss.

[0056] Figure 3-Figure 4 The trigger opening and closing structure includes a movable ball 6, the movable ball 6 of the baffle plate 7 mounted on the upper arc partition 11 is located below the baffle plate 7, and the movable ball 6 of the baffle plate 7 mounted on the lower arc partition 12 is located above the baffle plate 7, and the movable ball 6 is movably connected to the baffle plate 7 through a movable limiting connection structure;

[0057] During the rolling process, the grinding shell 51 makes the opening on the grinding shell 51 correspond to the position of the baffle plate 7 on the upper arc partition 11 and the baffle plate 7 on the lower arc partition 12. At this time, the movable ball 6 pushes open the movable sealing group 8 and the baffle plate 7 respectively, so that the opening on the grinding shell 51 is connected to the feed hole 111 or the discharge hole 121.

[0058] Through the setting of the movable ball 6, when the grinding shell 51 rolls to the position where the opening corresponds to the feed hole 111 or the discharge hole 121, extrusion is generated between the movable sealing group 8 and the movable ball 6, as well as between the movable ball 6 and the baffle plate 7, so that the movable sealing group 8 and the baffle plate 7 are both opened, thereby connecting the opening to the feed hole 111 or the discharge hole 121, so that the grinding roller 5 can automatically complete operations such as feeding and discharging when moving to the corresponding position, thereby realizing the effect of automatic feeding and discharging, and no additional control and power mechanism are required, which is convenient to use and reduces equipment cost.

[0059] Figure 3 The limiting connection structure includes a connecting rod 61 and a limiting plate 62. The connecting rod 61 is fixed on the movable ball 6. The connecting rod 61 movably passes through the middle of the baffle plate 7. The limiting plate 62 is fixed to one end of the connecting rod 61 away from the movable ball 6. The diameter of the limiting plate 62 is greater than the diameter of the connecting rod 61.

[0060] A notch 71 is provided in the middle of the baffle plate 7 . When the baffle plate 7 is closed, the connecting rod 61 moves through the notch 71 .

[0061] By setting the connecting rod 61 and the limit plate 62, the movable ball 6 can be movably installed on the baffle plate 7, so that the movable ball 6 can play the role of opening the baffle plate 7 and can not be separated from the baffle plate 7. The structure is simple and the movable ball 6 is easy to move and use.

[0062] Figure 4 The limiting connection structure shown also includes a first spring 63 and a fixed plate 64. The first spring 63 is fixed to the side of the limiting plate 62 at the discharge hole 121 away from the movable ball 6. The fixed plate 64 is fixed to the inner side walls of the front and rear ends of the processing box 1, and one side of the fixed plate 64 is fixed to the end of the first spring 63 away from the limiting plate 62.

[0063] A first spring 63 and a fixed plate 64 are arranged in the limiting connection structure at the feed hole 121, which can ensure that the movable ball 6 will not move downward a large distance under the influence of the squeezing pressure of the movable sealing group 8, causing the movable ball 6 to pass through the feed hole 121 and separate from the material blocking plate 7. At the same time, it can also ensure that the movable ball 6 can be supported by the elastic force of the first spring 63 when not affected by the squeezing pressure of the movable sealing group 8, thereby preventing the movable ball 6 from exerting pressure on the material blocking plate 7 in the feed hole 121, causing the material blocking plate 7 to open.

[0064] Figure 3-Figure 6 It is shown that the movable sealing group 8 includes a fixed ring 81, a movable block 82 and a slide rail 83. The fixed ring 81 is fixed in the opening of the grinding shell 51. The slide rail 83 is fixed to the inner wall of the fixed ring 81. The slide rail 83 is arranged parallel to the radial direction of the grinding shell 51. The movable block 82 is slidably connected to the fixed ring 81 through the slide rail 83. When the movable block 82 contacts the movable ball 6, the movable block 82 is separated from the fixed ring 81 and a gap is exposed, and there is a gap between the movable block 82 and the protrusion on the grinding core 52.

[0065] When the opening on the grinding shell 51 corresponds to the position of the feed hole 111 or the discharge hole 121, the movable block 82 is squeezed by the movable ball 6 and moves downward along the slide rail 83, so that the movable block 82 is separated from the fixed ring 81 and a gap is exposed. At this time, the opening of the grinding shell 51 is in an open state, so that the feed hole 111 or the discharge hole 121 is connected to the opening of the grinding shell 51.

[0066] It should be noted that in order to meet the requirement that the opening of the grinding shell 51 will be immediately closed after the movable ball 6 is separated from the movable block 82, the inner hole diameter of the fixed ring 81 is larger than the diameter of the movable ball 6, and the condition that the fixed ring 81 will not come into contact with the movable ball 6 when the grinding shell 51 continues to move is met, thereby avoiding the phenomenon that the movable ball 6 is lifted up by the fixed ring 81 after being separated from the movable block 82.

[0067] Figure 7 It is shown that a slide groove 831 is provided on one side of the slide rail 83 close to the movable block 82, and ear blocks 821 slidably connected to the slide groove 831 are integrally formed on both sides of the movable block 82;

[0068] A second spring 84 is fixed to one side of the ear block 821 close to the grinding core 52 , and the other end of the second spring 84 is fixed to the inner wall of one end of the slide groove 831 close to the grinding core 52 .

[0069] By setting the second spring 84, after the movable block 82 is separated from the movable ball 6, it will immediately return to its original position under the influence of the elastic force of the second spring 84, and cooperate with the fixing ring 81 to close the opening of the grinding shell 51, thereby preventing the ceramic raw material from leaking from the opening during the rolling process of the grinding shell 51.

[0070] Figure 7 It is shown that an elastic sealing piece 85 is fixed to the inner wall of one end of the slide groove 831 away from the grinding core 52, and the other end of the elastic sealing piece 85 is fixed to the side of the ear block 821 away from the second spring 84. When the elastic sealing piece 85 is stretched and deformed, it always seals the opening between the slide groove 831 and one side of the ear block 821.

[0071] The elastic sealing piece 85 can be provided to prevent the ceramic raw material from entering the slide groove 831 and causing blockage in the slide groove 831 , so that the ear block 821 can slide smoothly in the slide groove 831 .

[0072] Figure 1-Figure 2 It is shown that both sides of the processing box 1 are provided with vibration grooves 13 cooperating with the vibration mechanism 2;

[0073] A discharge pipe 14 is fixed and connected to the lower end of the processing box 1, and a recovery pipe 15 is fixed and connected to the middle part of the lower arc-shaped partition 12. The recovery pipe 15 is located directly below the feed hole 111. The inner diameter of the upper end of the recovery pipe 15 is larger than the maximum length of the feed hole 111. The lower end of the recovery pipe 15 is fixed and passes through the bottom wall of the processing box 1, so as to facilitate the collection of a very small amount of ceramic raw material that falls from the feed hole 111 during the closing process of the baffle plate 7, and to facilitate the guidance and discharge of a very small amount of ceramic raw material that falls on the lower arc-shaped partition 12 to avoid affecting the movement of the grinding roller 5 and facilitate subsequent recycling.

[0074] Second implementation method:

[0075] In order to make the rotation of the grinding shell 51 more stable and prevent the grinding shell 51 from being affected by the internal ceramic and causing rotation jamming, tooth blocks distributed along the circumference of the center axis of the grinding shell 51 are integrally formed on the outer peripheral side wall of the grinding shell 51, and a plurality of tooth blocks evenly distributed and meshing with the tooth blocks on the grinding shell 51 are also integrally formed on the upper surface of the lower arc-shaped partition plate 12, so that the grinding shell 51 can produce stable and reliable rotation during the reciprocating swing process, thereby ensuring the effective grinding of the ceramic raw material.

[0076] In view of current practical needs, the above-mentioned implementation mode adopted in this application is not limited to the scope of protection. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the scope of protection of the present invention.
