Description

Technical Field

[0001] This utility model relates to the field of chemical production technology, and in particular to a composite sealing device for a rotary kiln for calcining titanium dioxide. Background Technology

[0002] As the core equipment for titanium dioxide calcination, the rotary kiln needs to operate under specific temperature, pressure and atmosphere conditions to ensure the crystal transformation and quality stability of titanium dioxide. During the titanium dioxide calcination process, the sealing components are in a harsh environment of high temperature, high dust and strong corrosion for a long time, and the wear and aging rate is relatively fast, requiring regular inspection, maintenance or replacement.

[0003] Traditional sealing devices often use bolts or welding for fastening, requiring various tools for assembly and disassembly. Furthermore, some connection points are prone to corrosion and jamming due to prolonged high-temperature baking and dust accumulation. This not only increases maintenance time and labor intensity but may also cause additional damage to the kiln body or sealing device, affecting the overall service life of the equipment. Utility Model Content

[0004] In view of the technical problems in existing technologies, traditional sealing devices mostly use bolt fastening and welding fixing methods. Disassembly and assembly require the use of multiple tools, and some connection parts are prone to corrosion and jamming due to long-term high temperature baking and dust accumulation. This not only increases maintenance time and labor intensity, but may also cause additional damage to the kiln body or sealing device, affecting the overall service life of the equipment. This utility model provides a composite sealing device for a titanium dioxide calcining rotary kiln.

[0005] The technical solution adopted in this utility model is: a composite sealing device for a rotary kiln for titanium dioxide calcination, comprising a kiln body and a composite sealing plate. The composite sealing plate is installed on one side of the kiln body. A disassembly and assembly assembly for quick disassembly and assembly of the composite sealing plate is installed on the surface of the kiln body. The disassembly and assembly assembly includes a fixing frame fixedly installed on the surface of the kiln body. Four mounting rods arranged in a rectangular array are fixedly installed on one side of the composite sealing plate. Four mounting grooves that fit with the mounting rods are formed on the surface of the fixing frame. The mating structure of the fixing frame, mounting rods, and mounting grooves provides a basic framework for the quick disassembly and assembly of the composite sealing plate. The rectangular array of mounting rods and mounting grooves ensures accurate alignment during installation of the composite sealing plate, avoiding impact on the sealing effect due to installation misalignment. It also simplifies the initial positioning operation and improves disassembly and assembly efficiency.

[0006] Furthermore, each of the four mounting slots is provided with a snap-fit ​​rod on one side. The snap-fit ​​rod passes through one side surface of the fixing frame and is slidably connected to the fixing frame. A first sliding plate is fixedly installed on one side of the snap-fit ​​rod. The first sliding plate is slidably connected inside the fixing frame. A first spring is fixedly installed on one side of the first sliding plate. A slot that matches the snap-fit ​​rod is opened on one side of the mounting rod. The elastic force of the first spring can push the snap-fit ​​rod to automatically snap into the slot. Initial fixing can be completed without additional tools, making the operation convenient.

[0007] Furthermore, a first limiting rod is provided on the other side of the mounting groove. A second sliding plate is fixedly installed on one side of the first limiting rod. The second sliding plate is slidably connected inside the fixed frame. A second spring is fixedly installed on one side of the second sliding plate. A first limiting groove that matches the first limiting rod is opened on one side of the snap-fit ​​rod. During disassembly, the first limiting rod snaps into the first limiting groove, which can effectively limit the snap-fit ​​rod from resetting itself under the action of the first spring force, and prevent the snap-fit ​​rod from accidentally snapping back into the slot during disassembly.

[0008] Furthermore, two symmetrical fixing plates are fixedly installed on both the upper and lower sides of the fixing frame. A sliding rod is provided inside the fixing plate, which passes through the fixing plate and is slidably connected to it. A second limiting rod is fixedly installed on one side of the sliding rod, and a second limiting groove that matches the second limiting rod is also provided on one side of the snap-fit ​​rod. A third spring is fixedly installed on the surface of the sliding rod. After the snap-fit ​​rod is initially fixed, the second limiting rod automatically snaps into the second limiting groove under the elastic force of the third spring, further restricting its displacement from the direction perpendicular to the snap-fit ​​rod, which significantly enhances the stability of the snap-fit ​​structure.

[0009] Furthermore, both the first and second limiting rods are perpendicular to the locking rod, which improves the comprehensiveness and reliability of the limiting and ensures that the locking rod can maintain a stable state under various working conditions.

[0010] Furthermore, handles are fixedly installed on one side of the locking rod, the first limiting rod, and the second limiting rod, which makes it easier to operate and reduces the difficulty of operation.

[0011] Furthermore, a sealing column with a slightly smaller diameter than the kiln body is fixedly installed inside the composite sealing plate. Sealing gaskets are fixedly installed on both the inner surface of the composite sealing plate and the outer surface of the sealing column. One end of the kiln body is installed between the composite sealing plate and the sealing column, forming a multi-layered sealing structure. The sealing column is adapted to the inner diameter of the kiln body, and together with the sealing gaskets on the inner surface of the composite sealing plate and the outer surface of the sealing column, it can tightly fill the gap between the kiln body and the sealing plate.

[0012] The beneficial effects of this utility model are: This invention, through its modular design, allows for the rapid installation and removal of the composite sealing plate, facilitating its replacement. It solves the problem of traditional sealing devices relying on bolts and welding, which require multiple tools for assembly and disassembly. Furthermore, these methods often lead to corrosion and jamming at connection points due to prolonged high-temperature baking and dust accumulation. This not only increases maintenance time and labor intensity but can also cause additional damage to the kiln body or sealing device, affecting the overall lifespan of the equipment.

[0017] The following is in conjunction with the appendix Figures 1-4The present invention will be further described below.

[0018] In order to solve the problems existing in the background technology, this application proposes the following technical solution: a composite sealing device for a rotary kiln for calcining titanium dioxide.

[0019] The specific technical solution includes a kiln body 1 and a composite sealing plate 2. The composite sealing plate 2 is installed on one side of the kiln body 1. A disassembly and assembly assembly 3 is installed on the surface of the kiln body 1 to facilitate quick assembly and disassembly of the composite sealing plate 2. The disassembly and assembly assembly 3 includes a fixing frame 301 fixedly installed on the surface of the kiln body 1. Four mounting rods 302 arranged in a rectangular array are fixedly installed on one side of the composite sealing plate 2. The surface of the fixing frame 301 has four mounting grooves 303 that fit with the mounting rods 302. The mating structure of the fixing frame 301, the mounting rods 302, and the mounting grooves 303 provides a basic framework for the quick assembly and disassembly of the composite sealing plate 2. The rectangular array of mounting rods 302 and mounting grooves 303 ensures the accuracy of the alignment during installation of the composite sealing plate 2, avoiding any impact on the sealing effect due to installation misalignment. It also simplifies the initial positioning operation and improves the efficiency of assembly and disassembly.

[0020] Reference Figures 1 to 4 As shown, each of the four mounting slots 303 has a locking rod 304 on one side. The locking rod 304 passes through one side surface of the fixing frame 301 and is slidably connected to the fixing frame 301. A first sliding plate 305 is fixedly installed on one side of the locking rod 304. The first sliding plate 305 is slidably connected inside the fixing frame 301. A first spring 306 is fixedly installed on one side of the first sliding plate 305. A locking groove 307 that matches the locking rod 304 is opened on one side of the mounting rod 302. A first limiting rod 308 is also provided on the other side of the mounting slot 303. A second sliding plate 309 is fixedly installed on one side of the first limiting rod 308. The second sliding plate 309 is slidably connected to the fixing frame 301. Inside the fixed frame 301, a second spring 310 is fixedly installed on one side of the second sliding plate 309. A first limiting groove 311 that matches the first limiting rod 308 is opened on one side of the snap-fit ​​rod 304. The four mounting rods 302 on one side of the composite sealing plate 2 are aligned with the four mounting grooves 303 on the surface of the fixed frame 301 and inserted. The first limiting rod 308 is pulled outward, which drives the second sliding plate 309 to move. The second spring 310 is compressed. When the first limiting rod 308 is disengaged from the first limiting groove 311, the snap-fit ​​rod 304 is snapped into the slot 307 on one side of the mounting rod 302 by the elastic force of the first spring 306, thus completing the initial fixation.

[0021] Reference Figures 1 to 4As shown, two symmetrical fixing plates 312 are fixedly installed on both the upper and lower sides of the fixing frame 301. A sliding rod 313 is provided inside the fixing plate 312, passing through and slidably connecting with it. A second limiting rod 314 is fixedly installed on one side of the sliding rod 313. A second limiting groove 315 that matches the second limiting rod 314 is also provided on one side of the locking rod 304. A third spring 316 is fixedly installed on the surface of the sliding rod 313. The first limiting rod 308 and the second... The limiting rods 314 are all perpendicular to the locking rods 304. A handle 317 is fixedly installed on one side of the locking rods 304, the first limiting rod 308, and the second limiting rod 314. When the locking rod 304 is inserted into the slot 307 of the mounting rod 302, the second limiting groove 315 on one side of the locking rod 304 moves to the second limiting rod 314. The second limiting rod 314 moves towards the second limiting groove 315 by the elastic force of the third spring 316, thereby locking the locking rod 304 and further enhancing the stability during fixation.

[0022] Reference Figure 1 and Figure 2 As shown, a sealing column 4 with a slightly smaller inner diameter than the kiln body 1 is also fixedly installed inside the composite sealing plate 2. Sealing gaskets 5 are fixedly installed on the inner surface of the composite sealing plate 2 and the outer surface of the sealing column 4. One end of the kiln body 1 is installed between the composite sealing plate 2 and the sealing column 4. Sealing gaskets 5 are fixedly installed on the inner surface of the composite sealing plate 2 and the outer surface of the sealing column 4. The sealing gaskets 5 are in close contact with the surface of the kiln body 1, further filling the gap and effectively blocking the exchange of gases, dust and other substances inside and outside the kiln body 1, ensuring a sealed environment during the calcination process and ensuring the stable progress of the titanium dioxide calcination reaction.

[0023] To ensure that those skilled in the art can fully understand the technical solution, this application provides the following overall overview: In use, accurately align the four mounting rods 302 on one side of the composite sealing plate 2 with the four mounting grooves 303 on the surface of the fixing frame 301, and slowly insert the mounting rods 302 into the mounting grooves 303 until the inner surface of the composite sealing plate 2 is close to the end of the kiln body 1. At this time, one end of the kiln body 1 is initially between the composite sealing plate 2 and the sealing column 4. Pull the multiple first limiting rods 308 outwards respectively, causing the second sliding plate 309 to slide inside the fixing frame 301, and the second spring 310 is compressed and contracted. Continue pulling until the first limiting rod 308 is completely disengaged from the first limiting groove 311 on one side of the locking rod 304. After the first limiting rod 308 is disengaged from the first limiting groove 311, the first sliding plate 305, under the elastic force of the first spring 306, drives the locking rod 304 to move towards the mounting rod 302, so that the locking rod 304 is engaged in the locking groove 307 on one side of the mounting rod 302, thus achieving the initial fixation of the composite sealing plate 2. After the locking rod 304 is engaged in the locking groove 307, the second limiting groove 315 on one side of the locking rod 304 moves exactly to the second limiting rod 314. At this time, under the elastic force of the third spring 316, the second limiting rod 314 slides within the fixed plate 312 via the sliding rod 313, moves towards the second limiting groove 315 and engages therein, further limiting the engagement rod 304 and enhancing the stability of the fixation. If it is necessary to disassemble the composite sealing plate 2, pull the sliding rod 313 outward, causing the second limiting rod 314 to disengage from the second limiting groove 315 on one side of the engagement rod 304. Pull the engagement rod 304 outward, causing the first sliding plate 305 to slide inside the fixed frame 301, and the first spring 306 is stretched. Continue pulling until the engagement rod 304 is completely disengaged from the slot 307 on one side of the mounting rod 302. At this time, the first limiting groove 311 moves to the first limiting rod 308, and the first limiting rod 308 engages within the first limiting groove 311 by the elastic force of the second spring 310, thus limiting the engagement rod 304 and completing the disassembly of the composite sealing plate 2.
