Description

Technical Field

[0001] The present invention relates to the technical field of ceramic firing equipment, and specifically relates to a firing equipment for aluminum nitride ceramic grinding balls. Background Art

[0002] Aluminum nitride ceramic grinding balls are made through processes such as batching, grinding, powder making, forming, drying, and firing. They are mainly spherical stones widely used as grinding media. Firing is a very important step, which will directly determine the strength and wear resistance of the grinding balls. However, there are still some problems in the existing firing equipment during use, specifically as follows:

[0003] When the existing firing equipment fires grinding balls, a certain number of grinding balls need to be placed in the firing equipment. However, the existing bearing structures for placing grinding balls in the firing equipment are simple trays. The grinding balls are stacked in the firing space of the firing equipment, and then the grinding balls are fired centrally. In this way, since the internal grinding balls cannot rotate during the firing process, the grinding balls are unevenly heated during firing. The side facing the heat source is heated quickly, and the other side is heated slowly. As a result, it is very likely that the grinding balls will crack due to uneven heating during the firing process. In addition, the stacked grinding balls will cause indentations or firing adhesion due to the long-term stacking force at the contact parts of adjacent grinding balls during the firing process, which will greatly reduce the firing quality and the finished product rate of the grinding balls. For this reason, we propose a firing equipment for aluminum nitride ceramic grinding balls. Summary of the Invention

[0034] The technical solutions in the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the present invention. In addition, the forms of each structure described in the following embodiments are only examples. The firing equipment for aluminum nitride ceramic grinding balls involved in the present invention is not limited to the structures described in the following embodiments. All other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present invention.

[0035] Please refer to Figure 1-2 , a firing equipment for aluminum nitride ceramic grinding balls, comprising an outer housing 1, a sealing door 2 is movably installed on one side of the outer housing 1, an air outlet pipe is connected through the bottom end on the other side of the outer housing 1, an intake pipe 3 is movably installed on the top end of the outer housing 1, a driving device 4 is fixedly installed on one side of the outer housing 1, a transmission component 5 is movably installed on one side of the outer housing 1, a limiting groove 6 is opened on one side inside the outer housing 1, an inner housing assembly 7 is movably installed inside the outer housing 1, a separated combustion module 8 is fixedly installed inside the inner housing assembly 7, a containing assembly 9 is arranged and installed inside the inner housing assembly 7, a linkage component 10 is movably installed on one side of the inner housing assembly 7, and a lifting component 11 is fixedly installed on one side of the top end of the outer housing 1;

[0036] Compared with the prior art, in the present application, a containing component 9 for placing grinding balls is provided, and the grinding balls are not placed in a stacked state therein, so that the bonding of the grinding balls during the sintering process and the indentation caused by pressing contact can be avoided, and the integrity of the grinding balls during the firing process is ensured to the greatest extent. At the same time, after the inner shell component 7 is placed inside the outer shell body 1, it can still swing slightly, so that the grinding balls can roll inside the containing component 9, enabling the grinding balls to be heated more evenly during the firing process, thereby improving the firing quality of the grinding balls. At the same time, by providing a lifting component 11, the driving of the lifting component 11 can drive the linkage component 10 to move up and down, and then drive the containing component 9 to rotate self - sufficiently. In this way, combined with the slight swing of the inner shell component 7, the grinding balls can rotate axially inside the containing component 9 and also roll inside the containing component 9 along with the swing of the inner shell component 7. This can avoid the situation where the grinding balls are always fired in one place, thereby avoiding the bonding of the grinding balls during firing and the indentation generated between the grinding balls during long - term stacking and firing, and further improving the firing quality of the grinding balls.

[0037] Please refer to Figure 1-2 , a firing device for aluminum nitride ceramic grinding balls, including an air inlet pipe 3. One end of the air inlet pipe 3 is connected in a through - connection manner with an external gas supply device, and the other end of the air inlet pipe 3 is threadedly and hermetically connected to the top end of the inner shell component 7, and this connection end is of a hose structure;

[0038] In this embodiment, it should be noted that during the firing process of the grinding balls placed inside the inner shell component 7, the slight swing of the inner shell component 7 ensures the gas supply stability of the air inlet pipe 3, and thus ensures the combustion stability.

[0039] Please refer to Figure 1-4 , a firing device for aluminum nitride ceramic grinding balls, including a partitioned combustion module 8. The partitioned combustion module 8 and the containing component 9 are alternately installed inside the inner shell component 7. The partitioned combustion module 8 is fixedly installed in a through - connection manner with the top end of the inner shell component 7, and combustion ports are provided on the partitioned combustion module 8 at each height where the inner shell component 7 is located;

[0040] In this embodiment, it should be noted that this can ensure that the flame generated by combustion can directly fire the grinding balls at the position where each grinding ball is located, thereby ensuring the direct conduction of heat during firing and ensuring the firing effect. And because the interval between each adjacent partitioned combustion module 8 is small, the heat of the combustion flame ejected from the partitioned combustion module 8 can be well concentrated near the grinding balls, ensuring the full utilization of heat.

[0041] Please refer to Figure 1-7, A firing device for aluminum nitride ceramic grinding balls, including a transmission component 5. The transmission component 5 includes a central rod 51. One end of the central rod 51 is fixedly installed with a driven gear 52. The other end of the central rod 51 is provided with a straight groove 53. An inner channel is provided between the straight groove 53 and the outer side surface of the driven gear 52, and a locking push rod 54 is movably installed in the inner channel;

[0042] In this embodiment, it should be noted that the driving device 4 is composed of a driving motor and a driving gear. The driven gear 52 meshes with the driving gear. The straight grooves 53 are evenly spaced in layers and have the same position and size as the limiting grooves 6. The locking push rod 54 is slidably arranged in the inner channel. The end of the locking push rod 54 on the side where the straight groove 53 is located is provided with an inclined surface structure. The central rod 51 passes through the top of the inner channel of the driven gear 52 and is flush with the lower surface of the middle straight groove 53. In this way, the engagement between the inner shell component 7 and the transmission component 5 can be controlled by controlling the sliding of the locking push rod 54 in the inner channel. When the driving device 4 is pulled outwards, the inner shell component 7 is engaged with the transmission component 5. In this way, when the transmission component 5 rotates, it can drive the inner shell component 7 to rotate, that is, to realize a small swing of the inner shell component 7, so as to drive the horizontal rolling of the grinding balls in the inner loading component 9, ensuring the firing effect.

[0043] Please refer to Figure 1-9 , A firing device for aluminum nitride ceramic grinding balls, including an inner shell component 7. The inner shell component 7 includes an inner shell body 71. One side of the top end of the inner shell body 71 is provided with a docking thread groove 72. The bottom end of the inner shell body 71 is fixedly installed with a bottom support 73. One side of the inner shell body 71 is fixedly installed with a clamping structure 74. Two side grooves 75 are symmetrically provided on one side of the top end of the inner shell body 71. An upper guiding structure 76 is fixedly installed above one side of the inner shell body 71. A lower guiding structure 77 is fixedly installed below one side of the inner shell body 71;

[0044] In this embodiment, it should be noted that the docking thread groove 72 can be threadedly connected to the air inlet pipe 3. The top end of the inner shell body 71 is hollow and is connected to the partition combustion module 8 in a through manner. The other side of the top end of the inner shell body 71 is provided with an inclined surface, and the vertical projection area of the inclined surface perpendicular to the bottom support 73 is greater than or equal to the vertical projection area of the remaining part of the top end of the inner shell body 71 on the bottom support 73. A grid is provided on the bottom support 73 at the vertical position between two adjacent partition combustion modules 8. The top end of the linkage component 10 is movably arranged in the side groove 75. In this way, the inner shell body 71 can carry the loading component 9, and then the grinding balls are separated and arranged therein. And with the multi-burner setting of the partition combustion module 8, the grinding balls can be fired quickly and fully, improving the firing effect and also the firing efficiency.

[0045] Please refer to Figure 4-5, A firing device for aluminum nitride ceramic grinding balls, including a clamping structure 74. The clamping structure 74 includes a clamping bar 741. An inner groove 742 is formed on the clamping bar 741, and a clamping head 743 is movably installed inside the inner groove 742;

[0046] In this embodiment, it should be noted that the clamping bar 741 is fixedly arranged in the middle of one side of the inner housing 71 and is arranged at intervals in multiple numbers. It can be movably inserted and slidably arranged in the limiting groove 6 and the straight groove 53. The inner groove 742 is formed below the middle clamping bar 741. The clamping head 743 is installed in an inverted hook shape and can rotate. After the inner housing 71 is completely placed inside the outer housing 1, the locking push rod 54 can be pulled out to make the clamping head 743 automatically rotate downward into the inner groove of the central rod 51 for clamping and limiting. Thus, the whole inner housing assembly 7 and the transmission assembly 5 will not have relative sliding, and the transmission assembly 5 can drive the inner housing assembly 7 to swing slightly, so that the grinding balls inside can be rolled for comprehensive firing, ensuring the firing effect.

[0047] Please refer to Figure 3-9 , A firing device for aluminum nitride ceramic grinding balls, including an upper guiding structure 76 and a lower guiding structure 77. The upper guiding structure 76 includes an upper cross bar 761. A plurality of upper guiding blocks 762 are evenly fixedly installed on one side of the upper cross bar 761. The lower guiding structure 77 includes a lower cross bar 771. A plurality of lower guiding blocks 772 are evenly fixedly installed on one side of the lower cross bar 771. The upper guiding blocks 762 and the lower guiding blocks 772 are arranged in a staggered manner at corresponding positions, and inclined plane structures with opposite opening directions are formed on their opposite sides, and rollers are embedded and movably installed on the inclined planes;

[0048] In this embodiment, it should be noted that under the drive of the lifting assembly 11, the up and down movement of the linkage assembly 10 will realize the lateral movement and change the position in the vertical direction under the limiting and guiding action of the upper guiding block 762 and the lower guiding block 772. Thus, the linkage assembly 10 can drive the containing assembly 9 to rotate only in the vertical single direction, so as to ensure that the containing assembly 9 can continuously rotate in one direction to ensure the uniform heating and firing of the grinding balls inside.

[0049] Please refer to Figure 1-6 , A firing device for aluminum nitride ceramic grinding balls, including a containing assembly 9. The containing assembly 9 includes a bracket 91. A supporting frame 92 is movably sleeved on the bracket 91. A rotating gear 93 is fixedly installed at one end of the supporting frame 92;

[0050] In this embodiment, it should be noted that the bracket 91 is fixedly installed on the inner shell assembly 7 and the partition combustion module 8. The supporting frame 92 is of a cage-like structure and is horizontally provided with a reinforcing rib ring. Grinding balls are placed inside the supporting frame 92. The rotating gear 93 is meshed with the linkage assembly 10. In this way, when the inner shell assembly 7 swings slightly, it can drive the grinding balls inside the supporting frame 92 to roll, and when the linkage assembly 10 moves up and down, it can drive the rotating gear 93 to rotate. The combination of the two can achieve the comprehensive firing effect of the grinding balls.

[0051] Please refer to Figure 3-8 , a firing device for aluminum nitride ceramic grinding balls, including a linkage assembly 10. The linkage assembly 10 includes a straight rod 101. A docking hanging block 102 is fixedly installed at the top end of the straight rod 101. Suspension rods 103 are evenly and movably installed at the bottom end of the straight rod 101. A rack 104 is fixedly installed at the bottom end of the suspension rod 103. A lower guide block 105 is fixedly installed at the bottom end of the rack 104. An upper guide block 106 is fixedly installed at the top end of the rack 104.

[0052] In this embodiment, it should be noted that the docking hanging block 102 is L-shaped and a notch is opened at one end of the top end facing the outside of the outer shell 1. The bottom end of the lifting assembly 11 can be inserted into the notch. The suspension rod 103 is slidably arranged outside the inner shell 71. The suspension rod 103 is slidably installed at the bottom end of the straight rod 101. The rack 104 is meshed with the rotating gear 93. Both the lower guide block 105 and the upper guide block 106 are of inclined block structures. In this way, during the up and down movement of the straight rod 101, the lower guide block 105 and the upper guide block 106 can be used to laterally push the suspension rod 103, thereby controlling whether the rack 104 is meshed with the rotating gear 93, and then driving the supporting frame 92 to rotate, and further realizing the full and comprehensive firing of the grinding balls.

[0053] Please refer to Figure 2-10 , a firing device for aluminum nitride ceramic grinding balls, including a lifting assembly 11. The lifting assembly 11 includes an electric push rod 111. A cantilever 112 is fixedly installed at the top end of the electric push rod 111. A pull rod 113 is movably installed at the bottom end of the cantilever 112. A limiting short board 114 is fixedly installed at the lower end of one side of the pull rod 113. A supporting block 115 is movably installed at the lower end of one side of the pull rod 113.

[0054] In this embodiment, it should be noted that the pull rod 113 is rotatably arranged between the cantilever 112. The limiting short plate 114 limits the one-way rotation of the supporting block 115. The supporting block 115 can be inserted into the notch of the docking hanging block 102 for supporting. In this way, under the driving action of the electric push rod 111, the supporting block 115 can pull the linkage assembly 10 upward as a whole through the limitation of the limiting short plate 114, thereby driving the supporting frame 92 and the grinding ball to rotate. When it is necessary to take out or put in the inner shell assembly 7, the rotatable arrangement of the pull rod 113 and the rotatable arrangement of the supporting block 115 can ensure that there is no locking between the structures, so as to ensure the applicability of the device.

[0055] Working principle: Put the grinding ball into the inside of the supporting frame 92, and then send the inner shell assembly 7 as a whole into the outer shell 1 for placement. Pull out the locking push rod 54 outward. When the clamping joint 743 moves to the position of the locking push rod 54, turn it downward and clamp it into the inner channel of the central rod 51 to complete the locking connection between the inner shell assembly 7 and the transmission assembly 5. Close the closing door 2, and then dock the air inlet pipe 3 with the docking thread groove 72. Introduce and ignite the combustible gas. During the firing process, the drive motor of the driving device 4 rotates intermittently forward and backward, thereby driving the transmission assembly 5 to rotate forward and backward. In this way, the inner shell assembly 7 as a whole swings slightly continuously inside the outer shell 1, and the grinding balls inside the supporting frame 92 roll therein. The lifting assembly 11 will also be activated when the inner shell assembly 7 swings to a horizontal state. The docking hanging block 102 is lifted by the supporting block 115, thereby driving the rack 104 to move up and down. Under the mutual limiting and guiding action of the lower guide block 105 and the lower guide block 772 and the upper guide block 106 and the upper guide block 762, the rack 104 moves in one direction to drive the rotating gear 93 to rotate, thereby realizing the rotation of the grinding balls inside the supporting frame 92 and realizing the full firing of the grinding balls.

[0056] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
