Description

Technical Field

[0001] The present application relates to the technical field of classifiers, and in particular to a high-torque-resistance transition component and a 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] The existing grading wheel structures are mostly integrated grading wheels and split grading wheels. The ceramic body used for grading is a whole circle. The stress of the whole circle ceramic body is relatively concentrated during the sintering process, and the torque generated during the working process is mainly borne by the ceramic body. Once cracking occurs, the ceramic body can no longer be used. The cost and safety aspects need to be improved.

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

[0031] 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.

[0032] The existing grading wheel structures are roughly divided into two types: one is an integrated grading wheel, and the other is a split grading wheel. Both the integrated grading wheel and the split grading wheel use a full circle of grading ceramic as the ceramic body. The torque generated by the grading wheel during operation is borne by the ceramic. Once cracking occurs, the entire ceramic can no longer be used. The cost and safety aspects need to be improved.

[0033] In view of this, the embodiments of the present application aim to solve the above-mentioned technical problems, and therefore provide a high-torque-resistant transition component and a grading wheel. The high-torque-resistant transition component is applied to the grading wheel, which can withstand the torque acting on the grading ceramics at high speed, reduce the pressure on the grading ceramics, avoid ceramic cracking, and extend its service life.

[0034] For details, please refer to 1 and Figure 2 The present invention provides a high-torque-resistant adapter component for use in a classifying wheel. The adapter component comprises a cylindrical adapter body 1 configured as a thermally expandable body. The classifying wheel is provided with a mounting hole 51 for accommodating the adapter body 1. When the classifying wheel rotates, the adapter body 1 withstands the torque of the classifying wheel. This arrangement reduces the torque pressure on the classifying wheel's grading ceramics 5, preventing cracking, extending their service life, and reducing replacement costs.

[0035] In an optional example, the adapter body 1 is constructed of an iron-nickel-cobalt constant expansion ceramic sealing alloy (4J33) or an aluminum alloy. The thermal expansion coefficients of the iron-nickel-cobalt constant expansion ceramic sealing alloy and the aluminum alloy are almost the same as the thermal expansion coefficient of ceramics, and the two are more compatible, reducing the risk of assembly extrusion.

[0036] In an optional example, the adapter body 1 is constructed of metal stainless steel. When the adapter body 1 is constructed of metal stainless steel, a gap is reserved between the adapter body 1 and the mounting hole 51. It should be noted that because the thermal expansion coefficients of metal stainless steel and ceramics are different, the thermal expansion value of metal stainless steel is greater. In order to prevent excessive heat during operation from causing the adapter body 1 to expand excessively and squeeze the ceramic, the gap is reserved as a safeguard.

[0037] In another optional example, the adapter body 1 is constructed of austenitic stainless steel. When the adapter body is constructed of austenitic stainless steel, a gap is reserved between the adapter body 1 and the mounting hole 51. It should be noted that because austenitic stainless steel and ceramic have different thermal expansion coefficients, with austenitic stainless steel having a greater thermal expansion value, the gap is reserved as a safeguard to prevent excessive heat during operation from causing the adapter body 1 to expand excessively and squeeze the ceramic.

[0038] In addition, austenitic stainless steel is more corrosion-resistant and heat-resistant than metallic stainless steel. Those skilled in the art can select the material of the adapter body 1 according to actual needs.

[0039] In an alternative example, Figure 2 As shown, the high-torque-resistant adapter provided in the embodiment of the present application further includes fasteners 2, which are provided at both ends of the adapter body 1 to lock the adapter body 1 to the grading wheel. The fasteners 2 can be provided at the upper and lower ends of the adapter body 1, thereby locking the entire adapter body 1 into the mounting hole 51 of the grading wheel.

[0040] According to the high-torque-resistant adapter component provided in the embodiment of the present application, by constructing the adapter body 1 as a thermal expansion body and applying it to the grading wheel, when the grading wheel is working, it bears the high-speed torque of the grading ceramic 5, thereby reducing the risk of cracking of the ceramic, reducing the cost of using the ceramic, and extending its service life.

[0041] The embodiment of the present application further provides a grading wheel based on the above-mentioned high torque resistance transition component, such as Figure 1 and Figure 2 As shown, the grading wheel includes a fixing ring 4, a top cover 3, a grading ceramic 5, and the above-mentioned high-torque-resistant adapter component. The lower end of the grading ceramic 5 is set on the fixing ring 4, and the upper end cover of the grading ceramic 5 is provided with a top cover 3. The grading ceramic 5 is provided with a mounting hole 51. The adapter body 1 of the high-torque-resistant adapter component is set in the mounting hole 51, and the fastener 2 of the high-torque-resistant adapter component locks the adapter body 1 in the mounting hole 51. When the grading wheel is working, the power generated by the motor shaft drives the frame composed of the top cover 3 and the fixing ring 4 to rotate. Since the grading ceramic 5, which serves as the intermediate connecting part, is added with the high-torque-resistant adapter component, the torque transmitted thereto is borne by the high-torque-resistant adapter component, which reduces the torque pressure of the grading ceramic 5, prevents the grading ceramic 5 from cracking, extends its service life, and reduces replacement costs.

[0042] It should be noted that the number of adapter bodies 1 and mounting holes 51 needs to be set correspondingly, preferably 10. Ten adapter bodies 1 are set in 10 mounting holes 51 to ensure that they can sufficiently withstand the torque caused by rotation.

[0043] In one optional example, the end surface of the adapter body 1 near the top cover 3 is higher than the end surface of the mounting hole 51. That is, the upper end of the adapter body 1 is slightly higher than the upper end surface of the grading ceramic 5, and the connecting force of the grading ceramic 5 is borne by the adapter body 1. The majority of the torque generated during operation is borne by the adapter body 1, reducing the force on the ceramic, effectively improving the service life and safety of the grading wheel.

[0044] In an alternative example, Figure 3 As shown, the grading wheel provided in the embodiment of the present application further includes a patch 6 , which is arranged at one end of the adapter body 1 close to the fixing ring 4 to seal the adapter body 1 .

[0045] Furthermore, the patch 6 is L-shaped; the patch 6 is provided with a first stop 61 on the vertically arranged side, and the first stop 61 is connected to the side wall of the fastener 2; the patch 6 is provided with a second stop 62 on the horizontally arranged side, and the second stop 62 is connected to the fixing ring 4.

[0046] In an alternative example, Figure 2 As shown, the grading wheel provided in the embodiment of the present application also includes a first bottom ring ceramic 7 and a second bottom ring ceramic 8. The first bottom ring ceramic 7 is arranged on the upper end surface of the fixed ring 4, and the second bottom ring ceramic 8 is arranged on the lower end surface of the fixed ring 4. The first bottom ring ceramic 7 and the second bottom ring ceramic 8 are arranged correspondingly.

[0047] It should be noted that the first bottom ring ceramic 7 can prevent the second bottom ring ceramic 8 from moving upward, thereby playing the role of blocking materials.

[0048] The embodiment of the present application further provides a grading wheel based on the above-mentioned high-torque-resistant transition component. Since it includes the above-mentioned high-torque-resistant transition component, it has all the technical effects of the above-mentioned high-torque-resistant transition component. Compared with the grading wheel before the improvement, the grading wheel provided by the embodiment of the present application solves the technical problem that the whole-circle ceramic of the grading wheel is prone to cracking due to the high torque, which affects its service life and has high replacement costs.
