[0002] Magnesium oxide is an important chemical raw material, which is widely used in the manufacture of pharmaceuticals, ceramics, building materials, rubber products and other industries. Magnesium oxide calcining rotary kiln is a kind of equipment used to process magnesium oxide to improve the quality and efficacy of magnesium oxide particles.

[0003] At present, when a magnesium oxide calcining rotary kiln is in use, the raw materials and the combustion gas interact under high temperature and high pressure to form oxides and water vapor. During the combustion process, impurities such as particulate matter, dust and exhaust gas are generated. A vacuum cleaner is often installed on the top of the smoke chamber to speed up the discharge of smoke. However, due to the generation of particulate matter, the filter needs to be cleaned regularly to prevent the vacuum cleaner from being blocked. However, when the filter is disassembled, the vacuum cleaner needs to be disassembled as a whole, which is cumbersome and time-consuming. Moreover, for some larger particulate matter, it is impossible to collect them by relying solely on a vacuum cleaner. The operator needs to disassemble the smoke chamber as a whole to clean the large particles, which is time-consuming and labor-intensive. Therefore, a magnesium oxide calcining rotary kiln is urgently needed to solve the above problems.

The collecting cloth 52 and the driving strip 53 are both located inside the smoke chamber 2 and located at the bottom of the filter plate 61 and the dust hood 4. A groove adapted to the driving strip 53 is opened inside the smoke chamber 2, which can facilitate the collecting cloth 52 to be completely located at the bottom of the filter plate 61. The driving rod 54 is used to push the collecting cloth 52 to move toward the other side of the smoke chamber 2, so that the collecting cloth 52 is unfolded to facilitate the collection of large particles.

[0039] The bottom of the sealing strip 51 is fixedly connected to a connecting plate 58, which is located on the surface of the smoke chamber 2. One end of the connecting plate 58, which is away from the smoke chamber 2, is fixedly connected to a locking rod 59. A locking block 591 is movably sleeved inside the locking rod 59. The other end of the locking block 591, which is away from the locking rod 59, is circular and has a diameter larger than the locking rod 59, so that it can lock the hinged plate 57 and simultaneously achieve the purpose of positioning the driving rod 54. In addition, the locking rod 59 and the locking block 591 are snap-connected.

[0040] A slider 531 is fixedly connected to the top of the driving bar 53, and guide blocks 532 are fixedly connected to both sides of the collecting cloth 52 and located on the outside of the driving rod 54.

[0042] The disassembly part 6 includes a sealing plate 62 fixed to one end of the filter plate 61. The sealing plate 62 is located on one side of the smoke chamber 2 and on the top of the sealing strip 51. A magnetic block 63 is installed at the other end of the filter plate 61 and away from the sealing plate 62. The magnetic block 63 is located inside the dust hood 4. The sealing plate 62 can improve the sealing performance between the smoke chamber 2 and the inside of the dust hood 4. A handle is fixedly connected to one end of the sealing plate 62 and away from the filter plate 61 to facilitate the removal of the filter plate 61.

[0043] The disassembly part 6 also includes an iron block 64 installed on the inner side of the dust hood 4. The magnetic block 63 is located on one side of the iron block 64 and the two are magnetically connected.

[0045] During use, the vacuum cleaner 3 is started to absorb the dust and impurities inside the smoke chamber 2. Due to the suction force of the vacuum cleaner 3, large particles of impurities will be intercepted at the bottom of the filter plate 61. When collecting large particles, the driving rod 54 is directly pushed to push the collecting cloth 52 and the driving strip 53 along the inside of the sealing strip 51 toward the inside of the smoke chamber 2. During this process, the guide block 532 will slide along the inside of the smoke chamber 2, and the slider 531 will slide along the inside of the slide groove 533 at the bottom of the dust cover 4 until the other side of the driving strip 53 fits with the groove inside the smoke chamber 2. At this time, When the collecting cloth 52 is fully unfolded, the hinge plate 57 can be pulled to slowly rise with one end of the connecting rod 56 as the center, so that it is located on the surface of the locking rod 59, and then the locking block 591 is inserted into the locking rod 59. Since the circular diameter of one end of the locking block 591 is larger than the locking rod 59, the locking operation can be completed. Then, the vacuum cleaner 3 is turned off to cancel the suction force, and the large particles will directly fall onto the surface of the collecting cloth 52. Then, the bolts fixing the sealing strip 51 are removed, and the collecting piece 5 can be directly pulled out to process the large particles, which further achieves the purpose of simple operation.

[0046] When removing the filter plate 61, simply pull the handle to drive the sealing plate 62 and the magnetic block 63 to move toward the outside of the smoke chamber 2. When pulling, the magnetic block 63 and the iron block 64 can be disconnected, and then the filter plate 61 will move along the inside of the installation groove 65 toward the outside of the smoke chamber 2, thereby completing the purpose of removing the filter plate 61. When installing, the operation is the same, further achieving the purpose of simplicity and speed.
