Description

Technical Field

[0001] The present invention relates to the technical field of roasting, and in particular to a roasting device for an environmentally friendly and energy-saving rare earth catalyst. Background Art

[0002] Rare earth is the general term for seventeen metallic elements including lanthanide elements, scandium, and yttrium in the periodic table. There are 250 kinds of rare earth ores in nature.

[0003] In the prior art, such as a roasting device for an environmentally friendly and energy-saving rare earth catalyst with a high conversion rate, the Chinese patent number is: CN 214183134 U. It includes a box body. A feed pipe penetrates through the upper right end of the box body. A first motor is arranged at the upper end of the box body. The lower end of the first motor extends with a motor shaft, and one end of the motor shaft is fixedly connected with a rotating rod. A roasting cylinder is arranged inside the box body. The rotating rod extends into the roasting cylinder. A plurality of stirring blades are fixedly connected to the side surface of the rotating rod at equal intervals inside the roasting cylinder. Heating devices are fixedly connected to both inner walls of the box body. A collection box is fixedly connected to the right side of the box body, which can effectively achieve environmentally friendly and energy-saving use and can effectively improve the conversion rate of rare earth catalysts.

[0004] Although the above solution has the above advantages, the disadvantage of the above solution is that a large amount of materials are piled up together. Although the materials are turned over by stirring, because the amount of materials is too large, it takes a long time to turn them evenly, so the roasting time becomes longer, the speed becomes slower, and the efficiency is not high. Moreover, the prior art needs to filter through a suction fan and multiple filter meshes, and the use costs of the filter meshes and the suction fan are also relatively high. For this reason, we propose a roasting device for an environmentally friendly and energy-saving rare earth catalyst. Summary of the Invention

[0043] Embodiment 2

[0044] Refer to Figures 2-6 : This embodiment provides a technical solution on the basis of Embodiment 1:

[0045] The rotating mechanism 5 includes a second rotating shaft 56. The second rotating shaft 56 is rotatably connected inside the first heating cavity 601 and the second heating cavity 605.

[0046] The uppermost second air outlet 614 is communicated with the air collecting box 72, and one end of the elbow pipe 73 is located in the water.

[0047] Working principle:

[0048] Add materials into the interior of the barrel 2, and then start the forward rotation of the motor 31 to drive the first gear 32, the one-way first gear 42, and the reciprocating screw 41 to rotate, so that the moving plate 613 moves downward along the reciprocating screw 41 and the guide rod 43. At the same time, it drives the heating mechanism 6 and the filtering mechanism 7 to move downward and insert into the interior of the barrel 2, so that one side of the third gear 54 meshes with the second gear 52. Then, reverse the rotation of the motor 31 to drive the first gear 32 to drive the one-way second gear 59, the first rotating shaft 51, and the second gear 52 to rotate. The second gear 52 drives the third gear 54, the third rotating shaft 53, the first pulley 55, the belt 58, the second pulley 57, and the second rotating shaft 56 to rotate. The rotation of the second rotating shaft 56 drives the stirring cover one 603 and the stirring cover two 606 fixed thereto to rotate. The stirring cover one 603 drives the stirring rod one 604 to rotate, and the rotation of the stirring cover two 606 drives the stirring rod two 607 to rotate. During the slow insertion of the heating mechanism 6, the materials will be sleeved inside the first heating cavity 601, the second heating cavity 605, the third heating cavity 608, the stirring cover one 603, and the stirring cover two 606, dividing a large portion of the materials into multiple small portions of materials. Then, start the nozzle 610 to spray fire to heat the walls of the first heating cavity 601, the second heating cavity 605, and the third heating cavity 608. The hot air rising upward will cause the temperature at the top of the heating cavity to rise. Then, the heating cavity transfers the temperature to each portion of the materials to bake them. Dividing the large portion of the materials into several small portions of materials can bake all the materials faster and improve the baking efficiency. When the stirring cover one 603, the stirring rod one 604, the stirring cover two 606, and the stirring rod two 607 rotate, they stir the materials to make the baking of the materials more uniform and improve the baking speed. The gas generated during baking and the hot air in the heating cavity enter the gas collecting box 72 through the first air hole 609 and the second air hole 614, and then enter the water in the filtering box 71 through the elbow 73. The water filters the impurities in the gas, and then the gas rises. The filter net 74 filters the gas for the second time. The purpose of using water for primary filtration is to extend the service life of the filter net 74, and double filtration is cleaner.

[0049] As described above, it is only the preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present invention.
