Description

Technical Field

[0001] The utility model relates to the technical field of molybdenum oxide roasting, in particular to a rotary kiln for molybdenum oxide roasting. Background Art

[0002] The rotary kiln is a widely used equipment in the field of material processing and heat treatment. The rotary kiln is mainly composed of a cylinder, a support, a transmission device, a heating device and an exhaust gas treatment system. The cylinder is the main body of the rotary kiln, usually welded from heat-resistant steel plates, and has a certain inclination angle. The support is used to support the cylinder and allow it to rotate, and the transmission device drives the cylinder to rotate slowly through gears or chains. The rotary kiln for molybdenum oxide roasting usually adopts an external heating method, that is, a flame furnace is built outside the cylinder, and high temperature is generated by burning coal, natural gas and other fuels to heat the material in the cylinder.

[0003] For example, the Chinese patent "A Rotary Furnace for Calcination of Molybdenum Oxide" with publication number CN218821728U includes a rotary furnace body, and a cleaning structure is arranged in the rotary furnace body; the cleaning structure includes a cleaning ring which is slidably arranged in the rotary furnace body and matches the inner wall of the rotary furnace body, a screw rod is spirally penetrated through the upper end of the cleaning ring, and connecting seats are rotatably installed on the left and right ends of the screw rod, and the connecting seat is detachably installed on the rotary furnace body, a first gear is fixedly sleeved on the right end of the screw rod, a second gear is meshingly connected to the upper end of the first gear, a motor is connected to the upper wall of the second gear, and the motor is installed on the upper wall of the rotary furnace body.

[0004] Although the above-mentioned prior art can realize the roasting of molybdenum oxide, in actual use, on the one hand, the steps for removing molybdenum oxide are cumbersome. After the molybdenum oxide is roasted, the operator needs to use tools to remove the molybdenum oxide from the rotary kiln, which makes the steps for removing the molybdenum oxide inconvenient, thereby reducing the efficiency of the roasting operation. On the other hand, when the rotary kiln is roasting, the molybdenum oxide is easy to fall out from both ends of the rotary kiln. During roasting, the rotary kiln is in a rotating state. When the rotary kiln rotates, the molybdenum oxide is easy to fall out from the openings at both ends of the rotary kiln, thereby affecting the roasting of molybdenum oxide. Therefore, it does not meet the existing needs. In this regard, we propose a rotary kiln for roasting molybdenum oxide. Utility Model Content

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] 1. The utility model can rotate the rotating table together with the furnace body through the hydraulic telescopic device and the first fixed rod. Before roasting, the hydraulic telescopic device is turned on, and the rotating table is tilted by extending the telescopic end of the hydraulic telescopic device. According to the extension state of the hydraulic telescopic device, the connecting seat and the second rotating rod are rotated, and the first rotating rod is rotated on the first fixed rod at the same time, until the furnace body is rotated to a suitable angle to put in molybdenum oxide and adjust the furnace body to a horizontal state.

When molybdenum oxide is put into the furnace body, the furnace body is in a tilted state and the cover plate in the feed pipe is kept parallel to the furnace body until all the molybdenum oxide is put into the furnace body. At this time, the rotating motor is turned on to make the output shaft of the rotating motor drive the cover plate to rotate until the cover plate is rotated to be perpendicular to the furnace body. At this time, the feed pipe and the discharge pipe are respectively blocked by the cover plate to prevent the molybdenum oxide from falling out during roasting. At the same time, the cover plate is set to a mesh structure to maintain air circulation between the inside of the furnace body and the outside, thereby improving the roasting efficiency.

[0018] 3. The utility model can reduce the residual molybdenum oxide inside the furnace body through the guide bars and through holes. When the molybdenum oxide is roasted, the furnace body is in a rotating and tilted state. At this time, the molybdenum oxide inside the furnace body moves along the direction of the guide bars inside the furnace body until the molybdenum oxide is discharged from the furnace body through the discharge pipe. The through holes designed to penetrate the guide bars can reduce the adhesion of molybdenum oxide, thereby preventing molybdenum oxide from remaining inside the furnace body. At the same time, the guide bars can speed up the discharge of molybdenum oxide. BRIEF DESCRIPTION OF THE DRAWINGS
