Description

Technical Field

[0001] This utility model relates to the field of molybdenum oxide roasting technology, specifically to a raw material preheating device for a molybdenum oxide roasting furnace. Background Technology

[0002] In existing technologies, the drying, combustion, and subsequent processing of raw materials often present numerous problems. First, the drying and combustion processes are usually separate, requiring additional equipment or steps to transfer the dried raw materials to the combustion chamber. This not only increases operational complexity but may also lead to loss or contamination of the raw materials during the transfer process.

[0003] Secondly, the smoke produced during combustion often contains harmful gases, and direct emission of these gases pollutes the environment. Furthermore, the heat contained in the smoke is not fully utilized, resulting in energy waste. Traditional smoke treatment methods often simply involve emission or filtration, lacking effective recycling and utilization mechanisms.

[0004] Furthermore, during the mixing reaction, the raw materials and fumes are often not mixed evenly, resulting in low reaction efficiency. Traditional stirring methods often rely on mechanical stirrers, which have limited stirring effect and are easily affected by equipment limitations.

[0005] Furthermore, existing equipment often lacks an effective preheating mechanism, resulting in insufficient preheating of raw materials before they enter the drying chamber or combustion chamber, thus affecting subsequent processing efficiency and effectiveness. Simultaneously, the equipment has a low degree of automation, requiring significant manual operation, increasing labor intensity and production costs. While existing technologies may already offer solutions to these problems, this application aims to provide an alternative or replacement technical solution. Utility Model Content

[0006] To achieve the above objectives, this utility model provides the following technical solution: a preheating device for raw materials in a molybdenum oxide roasting furnace, comprising: a drying chamber, a combustion chamber, and a smoke filtration and heat conduction structure. The drying chamber is installed on the top of the combustion chamber, and the smoke filtration and heat conduction structure is connected to the drying chamber and the combustion chamber. The smoke filtration and heat conduction structure includes: a diversion pipe, a spider web diversion pipe, several siphon discharge pipes, a mixing reaction inner chamber, a raw material box, a quantitative feeding valve, an exhaust pipe, an inner stirring ring, an outer stirring ring, several conductive magnets, a drive gear rack, a drive gear, a stirring drive motor, a limiting ring support, several conductive metal blocks, and auxiliary stirring components.

[0007] The mixing reaction chamber is installed inside the drying chamber. The drainage pipe is inserted into the drying chamber, the combustion chamber, and the mixing reaction chamber. The spider web diversion pipe is installed on the drainage pipe and inside the mixing reaction chamber. Several siphon discharge pipes are evenly installed on the spider web diversion pipe. The raw material box is installed on the drying chamber. The quantitative feeding valve is connected to the mixing reaction chamber and the raw material box. The exhaust pipe is inserted into the drying chamber and the mixing reaction chamber. The limiting ring bracket is installed at the top of the drying chamber. The inner stirring ring and the outer stirring ring are mounted on the limiting ring bracket via bearings. Several conductive magnets are respectively mounted on the inner stirring ring, the outer stirring ring, and the auxiliary stirring assembly. The drive gear rack is mounted on the outer stirring ring. The stirring drive is mounted on the outside of the drying chamber. The drive gear is mounted on the drive end of the stirring drive, and the drive gear meshes with the drive gear rack. Several conductive metal blocks are evenly inserted into the limiting ring bracket, the drying chamber, and the mixing reaction inner chamber.

[0008] It should be noted that, as described above, the raw materials are guided to the inside of the drying chamber by the current feeding valve on the raw material tank. The dried raw materials fall into the inside of the combustion chamber. The smoke generated inside the combustion chamber is guided to the inside of the spider web diversion pipe through the diversion pipe. Several siphon exhaust pipes on the spider web diversion pipe guide the smoke to the inside of the mixing reaction tank. The stirring drive motor runs, driving the drive gear on the drive end of the stirring drive motor to rotate. The drive gear drives the drive rack meshing with it to rotate stably. The drive rack drives the outer stirring ring on it. The outer stirring ring drives the conductive magnet on it, which in turn transmits its magnetism to another conductive magnet through a conductive metal block. This conductive magnet drives the inner stirring ring, which in turn drives the auxiliary stirring component through its conductive magnet. This auxiliary stirring component then stirs the inside of the mixing reaction chamber and the drying chamber. Through the stirring in the mixing reaction chamber, the smoke and neutralized liquid are mixed, thereby converting harmful gases. At the same time, the smoke and heat generated by the chemical reaction are conducted to the inside of the raw material box for preheating.

[0009] Preferably, the auxiliary stirring assembly includes: a pair of annular support blocks, a pair of annular rotating inner blocks, several rotating blades, several metal conductive strips, several conductive magnet strips, several concave arc blocks, several convex annular blocks, several fitted annular racks, an external drive motor, an external loop block, an external drive shaft, and several external drive gears.

A pair of circular rotating inner blocks are mounted on the inner side of the mixing reaction chamber via bearings. Several rotating blades are respectively connected to the pair of circular support blocks and the pair of circular rotating inner blocks on both sides. Several metal conductive strips are evenly inserted into the drying oven and the mixing reaction chamber. Several conductive magnet strips are respectively mounted on several rotating blades. Several concave arc blocks are evenly installed on the inner side of the drying oven. Several convex circular blocks are movably inserted into several...

The outer drive shaft is inserted into the outer ring block through a bearing. The drive end of the outer drive motor is connected to the outer drive shaft. Several drive gears are evenly installed on the outer drive shaft, and the several drive gears mesh with several sets of ring racks. Several conductive magnets are respectively installed on several convex ring blocks, a pair of ring support blocks, and a pair of ring rotating inner blocks.

[0011] It should be noted that, as described above, the operation of the external drive motor drives the external drive shaft inside the outer ring block to rotate stably. The external drive shaft drives several external drive gears to rotate, which in turn drive the set ring rack meshing with the gears. The set ring rack drives the convex ring block on it, causing the convex ring block to rotate stably horizontally along the inner side of the concave arc block. The convex ring block drives the conductive magnet strip on it, and through the cooperation of the metal conductive strip, magnetic conduction is carried out on the rotating inner block. Similarly, magnetic conduction is carried out on the ring support block. Through the operation of several rotating blades, the drying oven and the mixing reaction chamber are stirred.

[0016] This utility model provides a preheating device for raw materials in a molybdenum oxide roasting furnace. It offers the following advantages compared to existing technologies: First, the raw material is precisely guided to the drying chamber via an electric feeding valve, and after drying, it automatically falls into the combustion chamber, achieving automation and continuity in raw material processing. The smoke generated in the combustion chamber is efficiently guided to the mixing reaction chamber through a diversion pipe and a spider web-like distribution pipe, ensuring full utilization of the smoke. The stirring drive motor drives the inner and outer stirring rings to rotate via a gear transmission system. Utilizing the magnetic transmission of a conductive magnet and a metal block, the auxiliary stirring components are magnetically driven, resulting in uniform and efficient stirring, improving the mixing effect of smoke and neutralized liquid in the mixing reaction chamber, and effectively converting harmful gases. Simultaneously, the external drive motor drives the external drive shaft to rotate, which, through gear meshing, drives the convex ring block to rotate stably horizontally, further enhancing the stirring effect and ensuring thorough mixing of the raw material and smoke. Furthermore, the device is equipped with a pressure relief valve, a pH sensor, a gas detector, a temperature sensor, and an auxiliary electric heater, improving the safety and controllability of the device and ensuring the smooth progress of the preheating process and the preheating effect of the raw material.

[0024] According to the appendix Figure 1-3First, the raw materials are precisely guided to the inside of the drying chamber 1 via the current feeding valve on the raw material box 7. After drying, the raw materials smoothly fall into the inside of the combustion chamber 2 for further processing. The smoke generated in the combustion chamber 2 is cleverly guided to the inside of the spider web diversion pipe 4 through the diversion pipe 3. Several siphon exhaust pipes 9 on the spider web diversion pipe 4, like a precise pipeline network, evenly guide the smoke to the inside of the mixing reaction chamber 6. At this time, the stirring drive 15 starts, driving the drive gear 14 on its drive end to rotate. The drive gear 14 meshes with the drive rack 13, making the drive rack 13 rotate stably. As the drive rack 13 rotates, the outer stirring ring 11 on it also rotates, thereby driving the conducting magnet 12 on the outer stirring ring 11. The conducting magnet 12 transmits its magnetism to another conducting magnet 12 through the conducting metal block 17, thereby driving the inner stirring ring 10 to rotate. The conducting magnet 12 on the inner stirring ring 10 further assists the magnetic drive of the auxiliary stirring component; under the synergistic effect of the auxiliary stirring component, the raw materials and fumes inside the mixing reaction chamber 6 and the drying chamber 1 are fully stirred. The fumes and neutralizing liquid inside the mixing reaction chamber 6 are fully mixed, and harmful gases are effectively converted. At the same time, the heat generated by the fumes and chemical reaction is transferred to the inside of the raw material box 7 through a clever conduction mechanism to preheat the raw materials; in addition, the operation of the external drive motor 26 also plays a key role. It drives the external drive shaft 28 inside the outer ring block 27 to rotate stably, thereby driving several external drive gears 29 on it to rotate. The gear meshing between the external drive gears 29 and the set ring rack 25 causes the set ring rack 25 to drive the convex ring block 24 on it to rotate stably horizontally along the inner side of the concave arc block 23. The 12 conductive magnets on the convex annular block 24, in conjunction with the metal conductive strips 21, magnetically conduct magnetically to the rotating inner block, and similarly to the annular support block 18. Ultimately, through the operation of several rotating blades 20, the drying oven 1 and the mixing reaction chamber 6 are thoroughly stirred, ensuring the smooth progress of the entire preheating process.
