Description

Technical Field

[0001] The present application relates to the technical field of classifiers, and in particular to a split classifying wheel. Background Art

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

[0003] Most of the existing grading wheels are integrated grading wheels, which are very expensive and have stress concentration at each corner during the sintering process. During operation, the rotational force of the motor shaft is directly transmitted to the grading wheel, and all torque is borne by the ceramic. The ceramic is prone to cracking during operation, and replacing the ceramic requires replacing the entire grading wheel, which increases the production cost.

[0004] Therefore, this field needs a new technical solution to solve the above technical problems. Utility Model Content

[0035] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0036] Most of the existing grading wheels are integrated grading wheels, which are very expensive and have stress concentration at each corner during the sintering process. During operation, the rotational force of the motor shaft is directly transmitted to the grading wheel, and all torque is borne by the ceramic. The ceramic is prone to cracking during operation, and replacing the ceramic requires replacing the entire grading wheel, which increases the production cost.

[0037] In view of this, the embodiments of the present application aim to solve the above-mentioned technical problems, and therefore provide a split grading wheel, which is assembled to form an integral grading wheel structure, which is convenient for disassembly. When a component of the grading wheel fails due to work, it is sufficient to replace one of the components in a targeted manner without replacing the entire grading wheel, thereby saving production costs.

[0038] For details, please refer to Figure 1 and Figure 4 The embodiment of the present application provides a split-type grading wheel, which includes: a fixed ring 6, a grading ceramic 3 and a top cover 1. The fixed ring 6 is a circular ring, the grading ceramic 3 is arranged on the outer edge of the fixed ring 6, and the top cover 1 is arranged on the grading ceramic 3; wherein, during the grading operation, the rotating shaft of the motor drives the top cover 1 to rotate, thereby driving the grading ceramic 3 and the fixed ring 6 to rotate to classify the material.

[0039] It should be noted that the top cover 1 is provided with a shaft hole for connecting to the motor shaft. The rotational force of the motor shaft acts on the top cover 1, thereby driving the grading ceramic 3 and the fixed ring 6 connected to the top cover 1 to rotate, thereby grading the material. Because the fixed ring 6, top cover 1, and grading ceramic 3 are manufactured separately, the sintering difficulty of each component is greatly reduced. Moreover, because the grading wheel is formed by assembly and is removable, if a component is damaged, only the damaged component needs to be replaced, without replacing the entire grading wheel, which reduces production costs.

[0040] In an alternative example, Figure 6 As shown, the graded ceramic 3 comprises several ceramic units evenly arranged along the circumference of the fixing ring 6. These units are connected end-to-end to form a ceramic body. This arrangement further disassembles the graded ceramic 3 into a composite of multiple ceramic units. If the graded ceramic 3 is damaged, only the damaged ceramic unit needs to be replaced, further reducing production costs.

[0041] Furthermore, each ceramic unit is provided with a reinforcement portion 31, and grading mesh openings 32 are evenly arranged between each adjacent reinforcement portion 31. In terms of shape, the grading ceramic 3 provided in the embodiment of the present application is composed of ceramic units, each of which is tile-shaped. To ensure the structural strength of the grading ceramic 3, each grading ceramic 3 is provided with a reinforcement portion 31. The reinforcement portion 31 is relatively wide. When the grading ceramic 3 is connected to form a full circle, the structure is relatively stable and can remain stable and non-deformed at high speeds. In addition, the grading mesh openings 32 ensure the grading effect of large particles.

[0042] In an alternative example, Figure 2 Shown and Figure 6 As shown, a first annular groove 11 is provided on the circumference of the top cover 1 , and a second annular groove 33 adapted to the first annular groove 11 is provided on one end of the graded ceramic 3 connected to the top cover 1 .

[0043] Further, such as Figure 3 and Figure 6 As shown, a third annular groove 61 is provided on the circumference of the fixing ring 6 , and a fourth annular groove 34 adapted to the third annular groove 61 is provided on one end of the graded ceramic 3 connected to the fixing ring 6 .

[0044] For example, the edge of the top cover 1 is provided with a first annular groove 11 for engaging with the second annular groove 33 of the grading ceramic 3. This secures the grading ceramic 3 to the top cover 1, thereby ensuring the stability of the grading wheel structure. Furthermore, a third annular groove 61 is provided on the inner circumference of the fixing ring 6. The fourth annular groove 34 of each grading ceramic 3 is inserted into the third annular groove 61 for securement. While ensuring connection, the grading ceramic 3 can also be well positioned to prevent misalignment of the entire assembled grading ceramic 3 structure.

[0045] In an alternative example, Figure 5 and Figure 7 As shown, a sealing air channel is provided at the connection portion between the fixed ring 6 and the grading ceramic 3; a plurality of separation protrusions 62 are provided along the inner side of the fixed ring 6, and the plurality of separation protrusions 62 are provided along the inner circumference of the fixed ring 6 with equal arcs. When the grading wheel rotates in a grading manner, centrifugal force is generated by the rotation of the separation protrusions 62 to prevent the material from entering the grading wheel through the sealing air channel. Furthermore, as shown in FIG..., the ends of the plurality of separation protrusions 62 are tilted, and the tilt direction and tilt angle are adjustable to ensure consistency. Through the above-mentioned setting of the fixed ring 6, the grading wheel provided in the embodiment of the present application can also form an outward centrifugal force at the bottom to prevent the material from entering the grading wheel through the sealing air channel, thereby ensuring the quality of the material.

[0046] In an alternative example, Figure 8As shown, the split-type grading wheel provided in the embodiment of the present application further includes a patch 5 , which is provided at the connection portion between the grading ceramic 3 and the fixing ring 6 and is used to seal the sealing air channel.

[0047] For example, the patch 5 is L-shaped; the patch 5 is provided with a first stop 51 on the vertical side, the first stop 51 is located in the middle of the vertical side, and the first stop 51 is embedded in the side wall of the graded ceramic 3; the patch 5 is provided with a second stop 52 on the horizontal side, the second stop 52 is located at the edge of the horizontal side, and the second stop 52 is connected and embedded in the fixing ring 6. It should be noted that the fixing ring 6 is provided with an annular groove on the outer circle of the bottom to facilitate the second stop 52 to be embedded and engaged in the annular groove. Through such a setting, during operation, the two stop structures prevent the patch 5 from being thrown out due to the action of centrifugal force, and effectively block the internal contact of the graded ceramic 3 with the material, while preventing the material from entering the interior through the sealed air channel, thereby ensuring the quality of the material.

[0048] In an alternative example, Figure 1 and Figure 4 As shown, the split grading wheel provided in the embodiment of the present application further includes a plurality of sleeves 2. The grading ceramic 3 is provided with a plurality of through holes 8, and the sleeves 2 are correspondingly arranged in the through holes 8. The sleeves 2 can share the rotation torque of the grading ceramic 3 to prevent the grading ceramic 3 from cracking.

[0049] In an alternative example, Figure 4 As shown, the split grading wheel provided in the embodiment of the present application further includes a first bottom ring ceramic 4, which is arranged on the upper end surface of the fixing ring 6, and the first bottom ring ceramic 4 is detachably connected to the fixing ring 6.

[0050] Furthermore, the split grading wheel provided in the embodiment of the present application also includes a second bottom ring ceramic 7, which is arranged on the lower end surface of the fixed ring 6, and the second bottom ring ceramic 7 is detachably connected to the fixed ring 6, and the first bottom ring ceramic 4 and the second bottom ring ceramic 7 are correspondingly arranged.

[0051] It should be noted that the first bottom ring ceramic 4 can prevent the second bottom ring ceramic 7 from moving upward, thereby playing the role of blocking materials.

[0052] According to the split classifying wheel provided in the embodiment of the present application, the integrated classifying wheel is disassembled into the split classifying wheel, and the classifying wheel body is formed by assembling the various components, thereby reducing the difficulty of sintering the classifying wheel. In addition, since the split classifying wheel is a detachable structure, the components therein can be disassembled at any time for repair and replacement. When the classifying wheel fails, there is no need to replace the entire classifying wheel, thereby reducing the production cost.
