[0002] Reactors are widely used in the fields of petroleum, chemical industry, rubber, pesticide, dye, medicine, food, etc. They are pressure vessels used to complete processes such as vulcanization, nitration, hydrogenation, polymerization, condensation, etc. The heat transfer form of infrared rays is radiation heat transfer, which transfers energy by electromagnetic waves. When far infrared rays irradiate the heated object, part of the rays are reflected back and part are penetrated. When the wavelength of the emitted far infrared rays is consistent with the absorption wavelength of the heated object, the heated object absorbs the far infrared rays, causing the molecules and atoms inside the object to "resonate", generating strong vibration and rotation, and the vibration and rotation increase the temperature of the object, achieving the purpose of heating.

The fastening groove 313 and the fastening column 203 are provided to improve the stability of the connection between the far-infrared heating sleeve 2 and the fixing plate 306.

[0033] When in use, the far-infrared heating sleeve 2 is placed in the installation groove 312 on the fixing plate 306. During the placement process, the fastening column 203 at the bottom of the limiting ring 202 is aligned with the fastening groove 313 on the fixing plate 306 and plugged in, so that the threaded fastening rod 204 at the bottom of the fastening column 203 is located at the bottom of the fixing plate 306, and the fastening nut 205 is screwed on the threaded fastening rod 204 for fixation, so that the bottom end face of the limiting ring 202 is in contact with the top end face of the fixing plate 306.

[0041] The working principle of the utility model is:

[0042] When installing the far-infrared heating sleeve 2, pull the fixing plate 306 out of the support plate 305 so that the mounting groove 312 on the fixing plate 306 is exposed to the outside, so that the installation space of the far-infrared heating sleeve 2 is larger, pull the second reinforcing column 307 in the first reinforcing column 320 so that its bottom is in contact with the ground, insert the reinforcing bolt 319 into the first reinforcing hole 321 and the second reinforcing hole 322 for fixing, so as to support the bottom of the fixing plate 306 pulled out of the support plate 305, insert the fastening column 203 on the far-infrared heating sleeve 2 into the fastening groove 313 on the fixing plate 306 one by one, screw the fastening nut 205 on the threaded fastening rod 204 and tighten it to fix the far-infrared heating sleeve 2 on the fixing plate 306 After the first reinforcing hole 321 and the second reinforcing hole 322 are fixed, the connection between the reinforcing bolt 319 and the first reinforcing hole 321 and the second reinforcing hole 322 is released, the second reinforcing column 307 is retracted into the first reinforcing column 320, the fixing plate 306 is pushed to drive the far-infrared heating sleeve 2 to move to the bottom of the reactor body 1, the hook 318 on the supporting plate 305 is rotated to engage with the clamping column 316 on the fixing plate 306 to prevent the fixing plate 306 from moving. Then, the two lifting cylinders 303 are started to drive the connecting plate 308 to drive the fixing plate 306 and the far-infrared heating sleeve 2 in the supporting plate 305 to move upward, so that the dustproof groove 201 in the far-infrared heating sleeve 2 is engaged with the dustproof clamping ring on the supporting plate 301, thereby ensuring the dustproof effect at the connection between the far-infrared heating sleeve 2 and the reactor body 1.

[0043] When disassembling and repairing the far-infrared heating sleeve 2, perform the above steps in reverse order to release the connection between the far-infrared heating sleeve 2 and the reactor body 1. It should be noted that when repairing the far-infrared heating sleeve 2, it is not necessary to release the connection between the far-infrared heating sleeve 2 and the fixed plate 306. The bottom of the fixed plate 306 pulled out of the support plate 305 is supported by the first reinforcing column 320 and the second reinforcing column 307, thereby improving the convenience of repairing the far-infrared heating sleeve 2.
