Description

Technical Field

[0001] The present application relates to the technical field of classifiers, and particularly to a classified ceramic and a classifier wheel including the classified ceramic. Background Art

[0002] The main function of the classifier wheel is to separate the coarse and fine particles in the material by the strong centrifugal force generated by high-speed rotation. During operation, the motor drives the classifier wheel to rotate at high speed in the classifier housing, forming a strong centrifugal force. The air-powder mixture entering the classifier first enters the inside of the classifier wheel. Under the action of the centrifugal force, the large or heavy particles are thrown to the periphery of the classifier wheel to the side wall of the classifier, and then naturally fall for further processing or collection; while the small or light materials are affected by a smaller centrifugal force and hover inside the classifier wheel to form a classification process.

[0003] The existing classifier wheel structures mostly adopt split classifier wheels. The ceramic main body is a complete circle. The stress is relatively concentrated during the sintering process of the complete circle ceramic main body, and the torque generated during the working process is mainly borne by the ceramic main body. Once cracking occurs, the entire ceramic main body cannot be used anymore, and there is still room for improvement in terms of cost and safety.

[0004] Therefore, a new technical solution is needed in this field to solve the above technical problems. Summary of the Utility Model

By assembling a plurality of ceramic monomers into a complete circle ceramic main body, if a cracking problem occurs, only the cracked ceramic can be replaced, and the disassembly and maintenance are convenient.

[0029] To make the objectives, technical solutions, and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Apparently, the described embodiments are some, but not all, of the embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts shall fall within the protection scope of the present application.

[0030] The existing grading wheel structures are generally divided into two types: one is an integrated grading wheel, and the other is a split grading wheel. Whether it is an integrated grading wheel or a split grading wheel, a whole-round grading ceramic is used as the ceramic main body, and the torque generated during the working process of the grading wheel is borne by the ceramic. Once cracking occurs, the entire ceramic cannot be used anymore, and there is still room for improvement in terms of cost and safety.

[0031] In view of this, the embodiments of the present application aim to solve at least one of the above technical problems. Therefore, a grading ceramic and a grading wheel including the grading ceramic are provided. By assembling a plurality of ceramic monomers into a whole-round ceramic main body, if a cracking problem occurs, only the cracked ceramic can be replaced, and disassembly and maintenance are convenient.

[0032] Specifically, please refer to Figure 1 and Figure 2, embodiments of the present application provide a hierarchical ceramic, which is applied to a grading wheel and includes a plurality of ceramic monomers 1. Each ceramic monomer 1 is in an arc structure, and the plurality of ceramic monomers 1 are connected end to end in sequence to form a ceramic body, and the ceramic body is in a hollow cylindrical structure.

[0033] It should be noted that the ceramic monomer 1 provided in the embodiments of the present application is in a tile-shaped arc structure, and it forms a ceramic body in a complete circular structure by connecting end to end in sequence. The ceramic body is in a hollow cylindrical structure (ring-shaped columnar). To ensure the assembled complete circular ceramic body, the ceramic monomers 1 can be connected by a strong bonding method or a splicing method that ensures strength. The embodiments of the present application do not specifically describe the connection method of the ceramic monomers 1.

[0034] In an optional example, the radian of each ceramic monomer 1 is 2π / n, where n is an integer greater than or equal to 3. That is, in the embodiments of the present application, there are at least 3 ceramic monomers 1. To ensure that the assembled ceramic body is in a complete circular structure, it is necessary to set the radian of each ceramic monomer 1 according to the above structural formula. Exemplarily, when the number of ceramic monomers 1 is 3, the radian of each ceramic monomer 1 is 2π / 3, that is, 120°.

[0035] It should be noted that in practical applications, those skilled in the art can adjust the number of ceramic monomers 1 according to the actual situation, which can be 4, 5, etc. The embodiments of the present application do not specifically limit the number of ceramic monomers 1, but such adjustments and changes to the number of ceramic monomers 1 do not deviate from the principle and scope of the present application and should be limited within the protection scope of the present application.

[0036] In an optional example, as Figure 1 shown, each of the ceramic monomers 1 is provided with a reinforcing portion 11, and the reinforcing portion 11 is configured to reinforce the structure of the ceramic body. For the structure of the tile-shaped ceramic monomer 1 as described above, in order to ensure the structural strength of the hierarchical ceramic, each ceramic monomer 1 is provided with a reinforcing portion 11. The width of the reinforcing portion 11 is relatively large. After being connected into a complete circular ceramic body, the structure is relatively stable and can remain stable at high speeds without deformation.

[0037] Further, each of the ceramic monomers 1 is provided with a grading mesh opening 12, and the grading mesh openings 12 are arranged at equal intervals along the extending direction of the radian of the ceramic monomer 1.

[0038] Still further, two rows of the grading mesh openings 12 are provided on the ceramic monomer 1.

[0039] It should be noted that the hierarchical network interface 12 is arranged on one side of the strengthening part 11, and is arranged in two rows vertically on the ceramic structure, separated by a relatively long horizontal bar in the middle, which can strengthen the structural strength of the ceramic while ensuring effective classification of the material, and further ensure that it does not break during the working state.

[0040] In an optional example, as Figure 1 shown, a connection hole 13 penetrating through the ceramic monomer 1 is arranged on the side edge of each ceramic monomer 1, and the connection hole 13 is used to install a connecting piece that can share the torque.

[0041] It should be noted that the hierarchical ceramic provided by the embodiment of the present application is applied to the classification wheel. To ensure the structural strength of the hierarchical ceramic and extend its service life, and further increase the service life of the classification wheel, the embodiment of the present application adds a connecting piece that can share the torque to the hierarchical ceramic. The connecting piece is a metal piece. During the classification rotation process, the rotational force generated by the rotation drives the hierarchical ceramic to rotate to classify the material, and the torque generated by the rotational force is borne by the metal connecting piece, further ensuring the structural stability of the hierarchical ceramic.

[0042] In an optional example, as Figure 1 shown, annular grooves 14 are arranged on the upper and lower sides of each ceramic monomer 1, and the annular grooves 14 are used to install the ceramic main body onto the classification wheel. The installation method of the annular grooves 14 will be introduced below.

[0043] According to the hierarchical ceramic provided by the embodiment of the present application, it is assembled by a plurality of ceramic monomers 1 into a ceramic main body. Compared with the integral round ceramic main body formed by sintering, the ceramic main body of this hierarchical ceramic is easier to sinter and manufacture. And during the classification work of the hierarchical ceramic, if a cracking problem occurs, only the cracked ceramic piece needs to be replaced, and the disassembly and maintenance are more convenient.

[0044] On the basis of the above hierarchical ceramic, the embodiment of the present application further provides a classification wheel, as Figure 2 and Figure 3 shown, including: a fixed ring 2, a top cover 3, and the above-mentioned hierarchical ceramic. The lower end of the hierarchical ceramic is arranged on the fixed ring 2, and the upper end of the hierarchical ceramic covers the top cover 3.

[0045] As described above, an annular groove is arranged on the inner circle of the fixed ring 2, and annular grooves 14 are arranged on the upper and lower sides of each ceramic monomer 1. Each hierarchical ceramic is inserted into the annular groove for fixation. On the basis of ensuring the connection, the hierarchical ceramic can also be well positioned to prevent the entire assembled hierarchical ceramic structure from being misaligned.

[0046] Furthermore, an annular groove is also provided at the edge of the top cover 3 for clamping with the upper edge of the grading ceramic. Then, through the annular grooves of the above-mentioned fixing ring 2 and the annular groove of the top cover 3, the grading ceramic is clamped and fixed between the two to ensure the stability of the grading wheel structure.

[0047] In a possible implementation manner, the grading wheel provided by the embodiment of the present application further includes a sleeve 4. The sleeve 4 is disposed in the connection hole 13 of the grading ceramic for sharing the torque during rotation. Corresponding to the above-mentioned grading ceramic structure, the sleeve 4 is a metal connecting piece. The sleeve 4 is slightly higher than the upper end face of the grading ceramic, and the connecting force of the fixing ring 2 is borne by the sleeve 4. Most of the forces generated during the working process are borne by the sleeve 4, and the ceramic is less stressed, effectively improving the service life and safety of the grading wheel.

[0048] In a possible implementation manner, as Figure 4 shown, the grading wheel provided by the embodiment of the present application further includes a patch 5. The patch 5 is disposed at the connection part between the grading ceramic and the fixing ring 2 for sealing the connection part between the grading ceramic and the fixing ring 2. The patch 5 is L-shaped; a first stop 51 is provided on the vertically arranged side of the patch 5. The first stop 51 is located in the middle of the vertically arranged side, and the first stop 51 is embedded and connected with the side wall of the fastener at the bottom end of the sleeve 4; a second stop 52 is provided on the horizontally arranged side of the patch 5. The second stop 52 is located at the edge of the horizontally arranged side, and the second stop 52 is embedded and connected with the fixing ring 2. It should be noted that the fixing ring 2 is also provided with an annular groove on the outer circle of the bottom to facilitate the second stop 52 to be embedded and clamped in the annular groove.

[0049] The grading wheel further provided by the embodiment of the present application on the basis of the above-mentioned grading ceramic includes the above-mentioned grading ceramic, and thus has all the technical effects of the above-mentioned grading ceramic. Compared with the grading wheel before improvement, the grading wheel provided by the embodiment of the present application solves the technical problems of high sintering difficulty and high replacement cost caused by the complex structure of the integral grading wheel or the whole-round ceramic.
